Abstract

The invention discloses a damage detection method, device, equipment, storage medium and damage detector, comprising: determining that the damage detector is restricted to slide within the specified range of the target steel strip, and the elastic part in the damage detector is in compression within the range state, the target steel belt is used to drag the elevator, and the surface of the target steel belt is covered with a target protective layer; the pressure value generated by the elastic part being squeezed by the target steel belt during the sliding process is collected; the pressure value is detected according to the pressure value pair The location of the target protective layer for damage detection. By obtaining the pressure value generated by the elastic part of the damage detector being squeezed by the target steel belt during the sliding process, and judging the damage of the target protective layer of the target steel belt according to the pressure value, it solves the need for maintenance in the prior art Personnel visually observe the damage of the target protective layer of the elevator traction steel belt, which brings about a large maintenance workload and high cost, and maintenance personnel are likely to miss inspections, resulting in potential safety hazards.

Description

technical field [0001] The embodiment of the present invention relates to elevator safety detection technology, and in particular to a damage detection method, device, equipment, computer-readable storage medium and damage detector. Background technique [0002] With the vigorous development of the elevator industry, more and more elevators use traction steel belts instead of traditional steel wire ropes as the traction medium of the elevator. The traction steel belt is composed of a set of solidified metal skeleton inside and a wear-resistant rubber sleeve densely wrapped outside the metal skeleton. After processing and forming, it can achieve the required composite properties of tensile strength, flexibility and wear resistance. [0003] Existing detection of the traction steel belt is mainly by detecting the metal framework inside the traction steel belt to determine whether the internal metal framework of the traction steel belt is broken. Then, the maintenance personne...
