具有防翻转功能爬楼小车的设计与性能研究

摘要

设计一款具有防翻转功能的爬楼小车，将传统的端面棘轮机构进行了巧妙的变形设计，应用于爬楼小车爬行中防翻转的单方向制动装置，由手动操纵线闸完成。通过运动仿真，针对小车爬楼梯过程进行了受力分析和运动学分析，优化了爬楼小车的结构，对提高爬楼小车的安全性具有应用价值。%This paper designs an upstairs cart with anti-reverse-rotation. Its modified design is derived from the traditional facing ratchet-wheel organization. It is applied to the unidirectional brake system which is used to prevent the upstairs cart from rol ing back. This device is operated by the manual cal iper brake. The upstairs cart structure is optimized through the motion simulation and the a-nalysis of motion and force. It is very important to improve its safety performance.
