1 绪论

矿山提升机是矿山大型固定机械之一,矿山提升机从最初的蒸汽机拖动的单绳缠绕式提升机发展到今天的交——交变频直接拖动的多绳摩擦式提升机和双绳缠绕式提升机已经历了170多年的发展历史,它是矿山井下生产系统和地面工业广场相连接的枢纽,被喻为矿山运输的咽喉。因此矿山提升设备在矿山生产的全过程占有重要的地位。

一个现代化的矿井在提升设备的选型上尤为重要。因为提升设备选型的合理与否,直接关系到矿井的安全和经济性,因此确定合理的提升系统时,必须经过多方面的技术经济比较,结合矿井的具体条件选择合适的设备。

根据矿井提升机工作原理和结构的不同,可分为缠绕式提升机和摩擦式提升机。单绳缠绕式提升机是较早出现的一种,它工作可靠,结构简单,但是仅适用于浅井及中等深度的矿井,而对于井深超过300米的矿井,宜选用多绳摩擦式绞车。在国内外,多绳摩擦式绞车飞跃发展,其发展速度远远超过单绳缠绕式提升机,这是因为它有着许多单绳缠绕式提升机无法比拟的优点,如提升钢丝绳直径较小,主导轮直径及整个机器的尺寸都相应缩小了,设备重量也减轻了,不需要设置防坠器等。下面是我针对不同的矿井的地质、煤层等情况,进行综合计算分析后,本着安全、经济等原则对这两种提升设备系统进行的选型设计。

目前我国煤炭95%是以井下方式开采,需要通过提升设备提升到地面以实现其使用价值和经济、社会效益。提升作为重要的一个环节,在一定程度上制约着煤炭生产能力。提升设备的合理结构及设计,安全经济运行和科学管理维护,直接关系到矿井生产能力及技术经济指标。现代采矿业的发展对提升设备在机械结构、工艺、设计理论和方法及安全检测等方面都有明确的要求。矿井提升设备的功能特点及生产的基本环节,提升设备的合理结构及设计、安全经济运行和科学管理维护直接关系到矿井生产能力及经济技术指标。国家将在“十一五”期间对有发展潜力的小煤矿进行改造提升以满足我国目前能源供应紧张的局面,更好的为全面建设社会主义小康社会提供“动力”支持。

目前我国中小型煤矿作为我国煤炭生产的重要部分其提升设备同大型煤矿及世界先进水平相比,仍有很大差距,主要表现在:

(1)提升设备的自动化水平较低,提升设备自动控制化控制较国内与国外大型和先进煤矿提升系统落后;

(2)提升设备的配套产品(钢丝绳、大型电机、减速器等)的质量安全性能尚不能满足要求,在一定程度上制约了提升设备的总体水平;

(3)矿井提升的监、检手段落后、制动系统的可靠性明显不足,有待进一步提高。

近几年煤炭开采与提升技术的发展速度很快,对提升机的要求必然随着先进技术的进步而不断发展,其发展趋势是:

(1)向适用型发展。

(2)向高耐久性,高可靠性方向发展。

(3)向智能化自动化方向发展。提升系统采用PLC控制监测系统等,并可根据要求调节,信号用声、光、影像来传送。

(4)向标准化、规范化方向发展。提升机零部件普遍标准化,规范化,保证设计、加工质量和水平。

(5)向高适应性发展。适应不同工作环境。

因此,研究制造自己的高效提升机是为经济发展和社会进步的长远考虑。本文首先综合比较了各种类型提升机的特点,根据经济效益和最大程度利用原则的实际情况选用了单绳缠绕式提升机的设计。然后,对多绳摩擦式提升机进行了总体结构设计并对其可靠性和可行性进行了分析。对提升机的主轴装置、联轴器、减速器、制动器等主要部件进行了技术分析和结构设计,完成了多绳摩擦式提升机的整体设计。此次设计的提升机主轴装置、减速器与制动系统是配套专用产品,电动机的选择可以灵活运用。这样可以使提升机的应用、维护、保养、检测等方面系统进行,有效提高提升机的工作效率。多绳摩擦提升机具有体积小、质量轻、安全可靠、提升能力强等优点,适用于较深的矿井提升。

 由于水平有限,难免出现错误,请指导老师和专家给予批评和指正。

Six Nordic laboratories performed fatigue tests on steel specimens. The laboratories also reported their results concerning uncertainty of measurement and how they calculated it. The results show large differences in the way the uncertainties of measurement were calculated and reported. No laboratory included the most significant uncertainty source, bending stress (due to misalignment of the testing machine, “incorrect” specimens and/or incorrectly mounted specimens), when calculating the uncertainty of measurement. Several laboratories did not calculate the uncertainty of measurement in accordance with the Guide to the Expression of Uncertainty in Measurement (GUM) 1.Keyword: Uncertainty of measurement, Calculation, Report, Fatigue test, Laboratory intercomparisonDefinitions :R Stress ratio Fmin/Fmax F Force (nektons) A and B Fatigue strength parameters s and S Stress (megapascals) N Number of cycles. IntroductionThe correct or best method of calculating and reporting uncertainty of measurement in testing has been the subject of discussion for many years. The issue became even more relevant in connection with the introduction of ISO standards, e.g. ISO17025 2. The discussion, as well as implementation of the uncertainty of measurement concept, has often been concentrated on which equation to use or on administrative handling of the issue. There has been less interest in the technical problem and how to handle uncertainty of measurement in the actual experimental situation, and how to learn from the uncertainty of measurement calculation when improving the experimental technique. One reason for this may be that the accreditation bodies have concentrated on the very existence of uncertainty of measurement calculations for an accredited test method, instead of on whether the calculations are performed in a sound technical way. The present investigation emphasizes the need for a more technical focus.One testing area where it is difficult to do uncertainty of measurement calculations is fatigue testing. However, there is guidance on how to perform such calculations, e.g. in Refs. 3, 4. To investigate how uncertainty of measurement calculations are performed for fatigue tests in real life, UTMIS (the Swedish fatigue network) started an interlaboratory comparison where one 4of the most essential parts was to calculate and report the uncertainty of measurement of a typical fatigue test that could have been ordered by a customer of the participating laboratories. For cost reasons, customers often ask for a limited number of test specimens but, at the same time, they request a lot of information about a large portion of the possible stress-life area from few cycles (high stresses) to millions of cycles (low stresses) and even run-outs. The way the calculation was made should also be reported. The outcome concerning the uncertainty of measurement from the project is reported in this article.ParticipantsSix Nordic laboratories participated in the interlaboratory comparison: one industrial laboratory, two research institutes, two university laboratories and one laboratory in a consultancy company. Two of the laboratories are accredited for fatigue testing, and a third laboratory is accredited for other tests. Each participant was randomly assigned a number between 1 and 6, and this notification will be used in the rest of this paper.Experimental procedureThe participants received information about the test specimens (without material data), together with instructions on the way to perform the test and how to report the results.The instructions were that tests should be performed as constant load amplitude tests, with R=0.1 at three different stress levels, 460, 430 and 400 Map, with four specimens at each stress level, at a test frequency between 10 and 30 Hz, with a run-out limit at cycles and in a 6510normal laboratory climate ( and relative humidity). This was considered as a 023C51%typical customer ordered test.The test results were to be used to calculate estimates of the two fatigue strength parameters, A and B, according to linear regression of the logs and long variables, i.e. . loglogABNThe reported result should include both the estimated parameters A and B and the uncertainties in them due to measurement errors. The report should also include the considerations and calculations behind the results, especially those concerning uncertainty of measurement.Several properties were to be reported for each specimen. The most important one was the number of cycles until fracture or if the specimen was a run-out (i.e. survived for cycles).6510The tests were to be performed in accordance with ASTM E-46696 5 and ISO5725-2 6. ASTM E-466-96 does not take uncertainty of measurement into account;However, ASTM E-466-96 mentions that the bending stress introduced owing to misalignment must not exceed 5% of the greater of the range, maximum or minimum stresses. There are also requirements for the accuracy of the dimensional measurement of the test specimen.All participants used hydraulic testing machines. The test specimens were made of steel (yield stress 375390 Map, and tensile strength 670690 Map, tabulated values). The test specimens were distributed to the participants by the organizer.ResultsThe primary laboratory results that should be compared are the estimated Whaler curves. In 5order to present all results in the same way, the organizer transformed some of the results. The Whaler curves reported by the participants are shown in Fig. 1.It can be seen that there are considerable differences between laboratories. An approximate statistical test shows a significant laboratory effect. Material scatter alone cannot explain the differences in the Whaler curves. In order to investigate if the laboratory effect was solely caused by the modeling uncertainty, we estimated new parameters from the raw data with a common algorithm. We then chose to use only the failed specimens and to make the minimization in the logarithmic life direction. The results are shown in Fig. 2. A formal statistical significance test was then made, and the result of such a test shows that the differences between the laboratories shown in Fig. 1 could be attributed only to modeling.Uncertainty of measurement calculationsOne of the most important objectives with this investigation was to compare the observed differences between laboratory test results with their estimated uncertainties of measurement. The intention was to analyze the uncertainty analyses as such, and to compare them to the standard procedure recommended in the ISO guide: Guide to the Expression of Uncertainty in Measurement (GUM) 1.The laboratories identified different sources of uncertainty and treated them in different ways. These sources are the load measurement, the load control, the superimposed bending stresses because of misalignment and the dimensional measurements. Implicitly, laboratory temperature and humidity, specimen temperature and corrosion effects are also considered. In addition, the results show a modeling effect. The different laboratory treatments of these sources are summarized in Table 1.Specific comments on the different laboratoriesAll laboratories gave their laboratory temperature and humidity, but did not consider these values as sources of uncertainty, i.e. the influence of temperature and humidity was neglected. This conclusion is reasonable for steel in the temperature range and humidity range in question 7.Laboratory 1. The uncertainty due to the applied stress was determined taking load cell and dimensional uncertainties into account. The mathematical evaluation was made in accordance with the GUM. Specimen temperature was measured, but was implicitly neglected. The modeling problem was mentioned, but not considered as an uncertainty source. Laboratory 2. The report contains no uncertainty evaluation. The uncertainties in the load cell and the micrometer are considered, but neglected with reference to the large material scatter. Specimen temperature was measured. Modeling problems are mentioned by a comment regarding the choice of load levels.Laboratory 3. The report contains no uncertainty evaluation. However, the accuracy of the machine is given and the load was controlled during the tests to be within specified limits. The 6bending stresses were measured on one specimen, but their influence on the fatigue result was not taken into consideration. Laboratory 4. The uncertainties in the load cell and the dimensional measurements are considered in an evaluation of stress uncertainty. The method for the evaluation is not in accordance with the GUM method, but was performed by adding absolute errors. The bending stress influence and the control system deviations are considered, but not included in the uncertainty evaluation. The failure criterion is mentioned and regarded as negligible, and corrosion is mentioned as a possible source of uncertainty. Laboratory 5. Uncertainties in the load cell and the load control were considered, and the laboratory stated in the report that the evaluation of the load uncertainty was performed according to the CIPM method. Laboratory 6. No report was provided, but only experimental results and a Whaler curve estimate.No laboratory reported the uncertainty in the estimated material properties, the Whaler parameters, but at most the uncertainty in the applied stress. The overall picture of the uncertainty considerations is that only uncertainty sources that are possible to estimate from calibration reports were taken into account in the final evaluation.Fig. 1 All experimental results and estimated Whole curves from the different laboratoriesNumber of cycles to failureOne important source that several laboratories mentioned is the bending stresses induced by misalignment in the testing machine, incorrectly mounted test specimens or “incorrect” specimens. The amount of bending stress was also estimated in some cases, but its influence on the uncertainty in the final Whole curve was not investigated.7The results from this experimental investigation show that there are different ways of determining the Whole curve from the experimental result. One problem is the surviving specimens, the run-out results. Four laboratories used only the failed specimens results for the curve-fit, one laboratory neglected all results at the lowest level, and one laboratory included the run-outs in the estimation. Another problem is the mathematical procedure for estimating the curve. Common practice, and the recommendation in the ASTM standard, is that the curve should be estimated by minimizing the squared errors in log life, i.e. the statistical model is, (1)logllogNabSWhere e is a random error, assumed to have constant variance, and where log stands for the logarithm with base 10. E can be interpreted as the combination of at least two types of errors: namely (1) a random error due to the scatter in the material properties, and (2) a measurement error due to uncertainties in the measurement procedures.Fig. 2 All experimental results and estimated Whole curves using the common procedureNumber of cycles to failureTable 1 Sources of uncertainty and laboratory treatment8C The laboratory report considers the source explicitly or implicitly, N the laboratory report neglects the source, A the laboratory report takes the source into account in the uncertainty of measurement calculationWhere e is a random error, assumed to have constant variance, and where log stands for the logarithm with base 10. E can be interpreted as the combination of at least two types of errors: namely (1) a random error due to the scatter in the material properties, and (2) a measurement error due to uncertainties in the measurement procedures. Stress was minimized, which led to a model discrepancy as discussed in the following.DiscussionExperimental resultsMost laboratories performed estimations of the Whaler curve parameters. Visual comparison of their estimated curves suggests differences, and a statistical test verified the conclusion that there is a statistically significant laboratory effect. A closer study of each participants procedure for determining the Whaler curve shows that the differences seem to be caused by different modeling of the curve.Since the test was intended to simulate a customer ordered test, some specific problems occurred. First, the number of test specimens is limited and therefore one should be careful when drawing conclusions from the results, since the scatter is considerable in fatigue and the number of specimens are limited.Another problem that occurred was that, since run-outs were wanted, two different failure criteria (failure mechanisms) were used to halt the test: fracture of the test specimen or 6510cycles. In the latter case, the use of the equation may cause problems, see loglogABNlater.The investigator then looked at whether any laboratory differences remained after excluding the model interpretation effects. This was accomplished in two ways:Namely, firstly by direct comparison of the experimental fatigue lives obtained, and secondly by using the same estimating procedure on all data sets. This therefore tested whether any laboratory differences remained or not. The first comparison was done on the two higher load levels. For these, no statistically significant differences were found. The second comparison, which included the failuresOn the lowest level, verified the result. Since the variation between laboratories is larger than the variation within a laboratory no statistically significant variation within a laboratory can be distinguished from the totalVariation in material.The conclusion is that no systematic errors in measurements were detected, but different modeling techniques give significant differences in the results. This in fact indicates that when different fitting models are used different quantities are measured even though they have the same name. Before any agreement is reached about the way of reporting fatigue data, it is of 9utmost importance that the modeling procedure is clearly defined in the test report. It is very important for the laboratories customers to be aware of this fact and, when requesting a test, to ask for a preferred modeling procedure as well as to be aware of the modeling procedure used by the laboratory when using fatigue data in design.Uncertainty evaluationAll laboratories made some considerations regarding the uncertainties of measurement. However, none of them evaluated uncertainties for the resulting Whole parameters, but only for the applied stress. However, none of the measurement uncertainties reported are unrealistic considering the factors taken into account, this is based inexperience. Since the specimens were destroyed during the tests it is not possible to separate the material variation from the repeatability. An estimate of the combined measurement uncertainty and the variation in material isAbout 30% of the lifetime and the major contribution are from the material variation and therefore one conclusion is that the measurement uncertainty in this test could be neglected during this test. This is not true for all fatigue tests and it is therefore anyhow interesting to study how the participants treated measurement uncertainty.Only one participant used the method recommended by the ISO guide GUM. This is surprising, since European accreditation authorities have recommended the GUM for several years. Among the uncertainty sources that were identified by the laboratories, only load cell measurement uncertainties and dimensional measurement uncertainties were taken into account. Important sources such as misalignment and load control were identified by some participants but were not included in the evaluation of stress uncertainty. Apparently only calibrated devices were considered for the overall uncertainty, and other sources, more difficult to evaluate, were excluded. No motivation for these exclusions can be found in the reports. One participant rejected the uncertainty evaluation with reference to the large scatter in fatigue lives. Our overall conclusion from the laboratory comparisons, that there are no detectable systematic effects, may be seen as verification of this rejection, but it is questionable if this was an obvious result beforehand. In contrast, for instance, uncertainties due to misalignment are not obviously negligible in comparison with the material scatter, and should be considered in an uncertainty analysis. This investigation, together with other observations 8, 9, shows problems with the introduction of the ISO17025 requirement for uncertainty of measurement statements. The reasons for this may be that the uncertainty of measurement discussion during recent years has concentrated very much on which equation to use and on administrative aspects, e.g. whether the uncertainty of measurement should alwa
