Single-side horizontal braking type elevator safety protection device

Abstract

The invention discloses a single-side horizontal braking type elevator safety protection device which comprises a shell fixed to a vertical moving object. A guide rail groove matched with a guide railis 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 installed in the shell. A locking and supporting rod extending in the horizontal direction is fixed to the shell, and comprises a fixed rod and a horizontal supporting rod. The fixed rod is fixed to the shell. The suspended end of thefixed rod is connected with one end of the horizontal supporting rod. The other end of the horizontal supporting rod is pivoted to the horizontal section of an L-shaped thumbing block. The connectingends of the horizontal supporting rod and the fixed rod are provided with a first shaft and a second shaft. The plane where the axis of the first shaft is located and the plane where the axis of the second shaft is located are in a horizontal state. The distance between the axis of the first shaft and the guide rail is smaller than the distance between the axis of the second shaft and the guide rail. Shaft holes matched with the first shaft and the second shaft are formed in the fixed rod. One end of a cranking rod is riveted to a trigger push rod. The other end of the cranking rod is rivetedto the second shaft.

Description

[0001] The present invention is a divisional application of the invention patent with the application date of December 22, 2016, the application number: 2016112012992, and the invention name "Single-side Horizontal Braking Elevator Safety Protection Device". 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 ...

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
