架空乘人楔形钢丝绳断绳抓捕装置的设计与仿真分析

Design and Simulation Analysis of an Overhead Rider Wedge Rope Breakage Catching Device

为进一步提升架空乘人装置的安全性,针对其钢丝绳失速、超限问题,设计了楔形钢丝绳断绳抓捕装置。其机械部件以楔形制动为主保证抓捕力,液压系统以差动结构为主保证装置的快速响应特性。经仿真分析表明,所设计的断绳抓捕装置可对架空乘人装置钢丝绳的失速、超限问题进行有效解决。

In order to further improve the safety of the overhead passenger device,a wedge-shaped rope breakage catching device is designed for its wire rope stall overrun problem.The simulation analysis shows that the designed rope breakage catching device can effectively solve the problem of stall speed over limit of wire rope of overhead passenger device.
