An elevator protection device with anti-drop effect

Abstract

The invention discloses an elevator protection device with an anti-falling effect, comprising an automatically retractable extendable connection structure, a supporting component, and a quick fixing device for a guide rail. The quick fixing device for the guide rail shoots a quick fixing nail toward the guide rail of the elevator to fix the guide rail of the elevator , the guide rail fast fixing device is used to clamp the elevator guide rail through the locking and fixing mechanism, and the extendable connection structure connects the bottom of the elevator car and the guide rail quick fixing device, including the upper arm and the lower arm that are hinged to each other, and the supporting component is installed on the connection On the assembly, when the elevator car falls down, the elevator car is pressed against the support plate, and the lower arm is obliquely supported between the fixed fixture main body and the support assembly. The present invention can promptly carry out emergency treatment on the elevator guide rails with loose bolts during the operation of the elevator, and strengthens the fixed support effect of the elevator car during the emergency stop and anti-drop process, and avoids excessive impact on local areas of the elevator guide rails.

Description

technical field [0001] The invention belongs to the technical field of elevator safety control systems, and relates to an elevator protection device with anti-drop effect. Background technique [0002] In the van elevator system, elevator guide rails that are consistent with the running direction of the elevator are installed in the elevator shaft. The function of the elevator guide rails is to guide the elevator running and ensure the stability of the elevator car. , the elevator car will activate the anti-falling device at the bottom of itself, and the anti-falling device realizes the emergency anti-falling fixation of the elevator car by clamping the elevator guide rail. Therefore, the reliability of the elevator guide rail installation directly affects the stability of the elevator operation and the Whether the fall arrest device can guarantee the safety of personnel when the danger of falling occurs. [0003] In most cases, the elevator guide rail is fixed to the side ...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide an elevator protection device with anti-falling effect, so as to solve the problem that the existing technology cannot timely deal with the elevator guide rails with loose bolts during the operation of the elevator, and the problem of the existing anti-fall device and elevator guide rails. The technical problem that the fixed structure is easy to damage the connecting structure of the elevator guide rail during the emergency stop locking process
