Elevator safety protection device with self-diagnosis function

Abstract

The invention discloses an elevator safety protection device with a self-diagnosis function. The elevator safety protection device comprises a protection device controller and a mounting bracket which are mounted at the bottom of an elevator car, wherein a detection module and an extensible connecting structure capable of being automatically folded are mounted on the mounting bracket; the extending end of the extensible connecting structure is connected with a guide rail quick fixing device; and after a locking fixing mechanism is locked and fixed with an elevator guide rail, time required for injecting a quick fixing nail into the side wall of an elevator shaft to fix the elevator guide rail by a nail injector is shorter than time required for completely unfolding the extensible connecting structure when the elevator car normally ascends. According to the elevator safety protection device disclosed by the invention, the elevator guide rail is detected in an elevator operation process, so that a loosened, broken or dropped bolt is found in the operation process; and after a problem is found, the elevator guide rail can be immediately subjected to emergency fixing treatment by injecting the quick fixing nail, so that elevator operation safety is greatly improved.

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...
