Integrated retarding device capable of degrading for use when failure occurs

Abstract

Provided is an integrated retarding device capable of degrading for use when failure occurs. The integrated retarding device mainly includes a clutch, a sun gear, peripheral gears and retarder units. The integrated retarding device solves the problems that an existing damping device has poor function integration, is not easy to install and use, has poor compatibility with existing elevator products, and fails completely when single point failure occurs. When partial retarding units fail, the whole performance of the integrated retarding device declines, but the function of the integrated retarding device is not completely lost, and therefore the integrated retarding device has the advantages of being safe, reliable, compact in structure, high in integration, optional in multi-function, wide in range of application and the like.

Description

technical field [0001] The present invention relates to the field of machinery, in particular to the speed limiting protection of mechanical rotary motion, especially after it is connected to the drive system of a traction elevator, it can reliably control the running speed of the elevator car within the set range, thereby realizing the limit protection of the car. run at high speed. Background technique [0002] With the increase in the number of high-rise buildings, the number of traction elevators has increased rapidly, but the problem of evacuation of people in high-rise buildings in emergencies such as fires has become increasingly prominent. ZL201210346849.5 "an elevator with self-running life-saving function in case of power failure in case of fire", which has been published, proposes a solution to realize the speed-limited operation of the car through the damping device, and can also simultaneously solve the problem of accidental stalling and falling of the car . ...

AI Technical Summary

Problems solved by technology

[0003] However, there are still many problems in directly adopting the existing damping device, such as one of which is the problem of poor functional integration of the damping device: either it does not have a clutch function, or an external control device must be added if it has a clutch function, etc., which will make The assembly structure is complex, requiring many operations, and the structure size is too large, and it is limited by the limited installation space of the existing elevator system, or it is difficult to install; for example, the damping device generally has a single point of failure, which leads to overall failure. Therefore, when used in emergency situations involving personal safety, it is necessary to improve its safety, so that even if there is a partial failure, it can be degraded and used to ensure safety; for example, the performance of the damping device is difficult to match the existing The problem of matching elevator products with different models and performances: If damping devices with corresponding performances are developed for each type of elevator, and tedious damping characteristic tests are carried out, there will be a long development cycle, poor economy, and Difficult to guarantee reliability and other issues will definitely affect the promotion and use of products
