小型立体车库设计 The Graduatio

n for Bachelor's Degree 摘要 在我国汽车保有量越来越大、停车问题越来越严重的情况下，开发适合我国国情的立体车库，是解决停车问题的有效途径。车辆无处停放的问题是城市的社会、经济、交通发展到一定程度产生的结果，我国也于90年代初开始研究开发机械立体停车设备，距今已有近二十年的历程。由于很多新建小区内住户与车位的配比为1:1，为了解决停车位占地面积与住户商用面积的矛盾，立体停车设备以其平均单车占地面积小的独特特性，已被广大用户接受。 在此设计中，通过利用杠杆和链传动曳引活动梁实现对汽车的二层存取。 在完成确保双层车辆均可自由存取的总体框架的设计后，对链传动存取车辆装置及其零部件、活动梁及停车梁等主要结构及其零部件进行计算校核。 该立体车库结构简单，操作方便，成本低廉，比较适合于家庭用户。 关键词：立体车库；杠杆；链传动;曳引；校核 ABSTRACT I
