1 绪论

1.1立体车库的概述

我国的汽车行业发展势头迅猛,汽车数量正在逐年上升,对立体车库的需求量越来越大。立体车库有诸多优点,在占地面积相同的情况下,立体车库的停车效率是普通车库的双倍甚至更高,立体车库在管理上也变得很方便。随着经验的积累,立体车库的控制系统也变得越来越智能,操作简单且安全可靠。从另一方面讲,立体车库的发展解放了大量劳动力,从而使他们的时间可以应用到其他方面。总之,立体车库将成为社会发展必不可少的工具。

垂直升降类立体车库在我国的发展比较快,,特别是一些电梯企业,由于垂直升降类立体车库的原理与电梯的工作原理相似,已经开始着手设计。据不完全统计,我国的停车设备公司已经向社会提供了2100多车位的垂直升降类立体车库,占各类机械式立体车库车位数量排名第3位。

垂直升降类立体车库的发展是跟我国的国情相符合的,我国人口众多,私家车众多,人均占地面积少,而垂直升降类立体车库可以建得很高,平面和空间利用率是普通车库的几倍甚至数十倍。垂直升降类立体车库的安全措施也比较齐全,控制系统非常先进,运行平稳,管理人员只需电脑操作就能实现车辆的存取。

本次设计的主要结构包括载车板、车库钢架、升降机构、减速系统。

升降机构通过载车板实现车辆的上升和下降动作,并可以使车辆准确平稳的到达或离开要停放的车库位置。升降机构以钢丝绳加卷筒的形式实现,由电机、减速器、卷筒、滑轮、钢丝绳等构件组成,电机和减速器之间,减速器和卷筒之间用联轴器连接;车库钢架主要用来承受车库自身的重量以及汽车和载车板的重量。车库钢架采用4立柱式,车库钢架的支柱在支撑整体重量的同时作为滑轮的导轨,起到平衡和束缚载车板运动轨迹的作用;载车板最高可以上升到2.5米。

1.2立体车库的研究现状

1.2.1国外立体车库的研究现状

国外的立体车库起步比较早,技术已经非常成熟。以美国、日本、德国为例,70年代末的经济迅速发展,使汽车行业迅速膨胀,停车技术应运而生。停车设备由一开始的家庭式双层停车库发展到后来的停车楼停车塔,车库的种类也从单一的简易升降类变为升降横移类、巷道堆垛类、垂直升降类等,每种类型的立体车库都有其特点。升降横移类立体车库建设周期短,成本低,比较经济。巷道堆垛类立体车库成本比较高,适合车位多的情况下使用。垂直升降类的立体车库高度非常高,对设备的安全性能要求苛刻,但是其比较先进,车位也比较多,效率非常高。随着越来越多的科研力量投入到立体车库的研究中,使立体车库向其他方面发展,立体车库越来越多的融入了如机械、电子、液压、光学、磁控和计算机等各领域的所有成熟先进技术,设备的材料越来越优化,控制方式越来越方便、简单、灵活。设备结构采用新型优质钢材,既提高了设备的强度和刚度,又使设备轻巧美观,载车板采用一次成型技术,表面镀锌,美观、强韧、耐用。控制技术方面,现在发达国家广泛采用可编程控制器和矢量变频变压调速闭环控制技术,使立体车库运行高速平稳,而且节省电力,震动和噪音可趋于最小化。控制形式多种多样,有按钮式、锁匙式、一些商场等采用IC卡式、更高级的有键盘式、触摸屏式。立体车库甚至开始追求美学。在一些建筑里,立体车库成为了必不可少的结构,一些工程师甚至将立体车库当成艺术来设计,在追求实用的同时加入了视觉冲击,或者加入了环保因素。随着时代的变迁,立体车库的设计主题已经变得越来越多样化。
