限速器—安全钳系统是在电梯发生下行超速和断绳时起保护作用的安全装置,其动作正常与否不仅关系到电梯的运行安全,更关系到人们的生命及财产的安全。因此检验机构必须加强对电梯的限速器—安全钳系统进行细致检查与试验,从而保证电梯安全、高效地运行。1限速器—安全钳联动失效现象在我们大量检验工作中,发现有的限速器—安全钳联动试验失效的现象,试验时未能实现安全钳夹紧导轨以致曳引钢丝绳打滑或者松弛,在机房表现为限速器绳轮与钢丝绳之间发生打滑。经多次观察限速器—安全钳联动试验失效的故障多数不在限速器上,而是出自安全钳传动环节上。在限速器—安全钳联动试验中(短接限速器和
Speed limiter - The safety gear system is a safety device that plays a protective role in the event of an overspeed and breakage of an elevator. Its normal operation is not only related to the safe operation of the elevator, but also to people’s lives and property. Therefore, the inspection agency must strengthen the detailed inspection and test of the elevator speed limiter-safety clamp system so as to ensure the safe and efficient operation of the elevator. 1 Speed limiter - safety pliers linkage failure phenomenon In our large number of inspections, we found that some speed limiter - safety pliers linkage test failure phenomenon, the test failed to achieve the safety pliers to clamp the guide rails so that the traction rope slipping or slack, In the engine room, slip occurs between the speed governor sheave and the wire rope. After many observations, the failure of the speed limiter-safety gear linkage test is mostly not on the speed limiter, but is from the safety gear transmission link. In the speed limiter-safety force linkage test (short-circuiting the speed limiter and
