An elevator safety protection device with self-diagnosis function

Abstract

The invention discloses an elevator safety protection device with a self-diagnosis function, which comprises a protection device controller installed at the bottom of the elevator car and a mounting bracket. A detection module and an automatically retractable extendable connection are installed on the mounting bracket. structure, the protruding end of the extensible connection structure is connected with a guide rail fast fixing device, and after the locking and fixing mechanism is locked and fixed with the elevator guide rail, the nail shooter shoots the quick fixing nails into the side wall of the elevator shaft The time required to secure the elevator guide rails is less than the time required for the extendable connection structure to fully deploy during normal ascent of the elevator car. The invention detects the elevator guide rails during the operation of the elevator, so that loose, broken or falling bolts are found during the operation. After the problem is found, the elevator guide rails can be quickly fixed by injecting fast fixing nails, which greatly improves the safety of the elevator. security of operation.

Description

technical field [0001] The invention belongs to the technical field of elevator safety control systems, and relates to an elevator safety protection device with self-diagnosis function. 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 fixe...
