Sensing interval adjustable type elevator falling protector

Abstract

The invention discloses a sensing interval adjustable type elevator falling protector. The elevator falling protector is characterized by comprising a shell fixed to a vertical moving object, a guiderail groove matched with a guide rail is formed in the shell, guide wheels matched with the surface of the guide rail in shape and located at the left end and the right end of the guide rail groove are arranged in the shell, a locking supporting rod extending in the horizontal direction is fixed to the shell, the suspended end of the locking supporting rod is hinged to one end of a thumbing block,a threaded section of a lead screw is in screw-thread fit with a balancing weight, a trigger spring is installed between the thumbing block and the locking supporting rod, when one end of the triggerspring is installed on the upper side of the locking supporting rod, the trigger spring is in a stretched state in the initial state, and when one end of the trigger spring is installed on the lowerside of the locking supporting rod, the trigger spring is in a compressed state in the initial state. The elevator falling protector can be repeatedly used and is convenient to detach manually; no destructive influences can be caused to the falling protector in the detaching process, and the detaching safety is improved.

Description

[0001] The present invention is a divisional application of an invention patent with an application date of December 22, 2016, an application number of 2016112012992, and an invention title of "Single-side push type fall arrester". technical field [0002] The invention relates to a mechanical fall arrester. Background technique [0003] The anti-fall device is mainly used in the safety protection of elevators and elevators to avoid damage to personnel and equipment caused by the rapid decline of elevators and elevators. [0004] The applicant retrieved the patent fall arrester (application number: 2006201040581) issued by Yiwu Shuanglin Lifting Equipment Installation Engineering Co., Ltd. on May 29, 2006. It is an existing conventional fall arrester structure, which adopts a wedge-shaped structure Double-sided clamping is fixed and locked. [0005] The general disadvantages of the existing fall arresters are: (1) they can only be used once, once they are triggered and work...

AI Technical Summary

Problems solved by technology

[0005] The general disadvantages of the existing fall arresters are: (1) they can only be used once, once they are triggered and work, the huge impact force will damage the internal structure, and they cannot be recycled or used multiple times; (2) they are stuck and difficult to disassemble, Because it adopts the wedge-shaped slot structure for double-sided clamping, the tight engagement between the wedge-shaped slider and the wedge-shaped slot makes it difficult for the operator to disassemble; (3) Safety issues during the disassembly process, the disassembly process will damage the fall arrester structure and cause it not to work properly, once it is loose, it may cause the car to fall rapidly
