摘要
电梯对重侧有时会设置安全钳,其作用主要有两种,一是对轿厢和对重之下有人能够到达的地下空间进行防护,二是作为上行超速保护装置。针对这两种不同作用的对重安全钳的区别,从设置目的、发展历史、运行原理和组成、与之配套的限速器的几方面要求对这两种不同作用的对重安全钳进行比较和分析,以供参考。
Some times counterweight safety gear is installed. There are two kinds of safety gears, one kind is to protect the passengers under lift car or counterweight, another one is to prevent over speed of the rising car. In this paper, the purpose, development, operating principle, structure of these two kind counterweight safety gears are introduced, and requirement of relative over speed governors are compaired and analyzed for reference.
