Elevator fault diagnosis and protection system

Abstract

The invention discloses an elevator fault diagnosis and protection system. The elevator fault diagnosis and protection system comprises a control center of an elevator system, wherein the control center is provided with an elevator car positioning module which is used for tracking and positioning an elevator car. The system also comprises a diagnosis controller, a detection module, an extendable connection structure and a guide rail quick fixing device, wherein the diagnosis controller, the detection module, the extendable connection structure and the guide rail quick fixing device are arranged below the elevator car; the guide rail quick fixing device is connected with the bottom of the elevator car through the extendable connection structure; the diagnosis controller and the detection module are mounted at the bottom of the elevator car; the guide rail quick fixing device comprises a sliding carrier which is connected with an elevator guide rail in a sliding manner, an electromagnetic claw which is mounted on the sliding carrier, a fasting tool, a position sensor and a fixing device control module. According to the elevator fault diagnosis and protection system disclosed by the invention, the elevator guide rail is detected in an elevator operation process, temporary strengthening of the elevator guide rail is realized in an elevator operation process so as to ensure the security; and meanwhile, adjustment can be performed according to the operation speed of the elevator so as to avoid influencing the stability of the elevator.

Description

technical field [0001] The invention belongs to the technical field of elevator safety control systems, and relates to an elevator fault diagnosis and protection system. 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 wa...
