Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator traction rope detection device. Background technique [0002] The traction rope of the elevator is mainly composed of multiple steel cables. Due to long-term work, the steel cables will inevitably have defects such as disconnection and damage, which will weaken the tensile capacity of the steel cables, thereby affecting the safe operation of the elevator. Therefore, in The elevator traction rope needs to be checked during the daily maintenance of the elevator. At present, the commonly used inspection method is to visually inspect whether each steel cable of the elevator has obvious defects, but this method is prone to omissions, and smaller defects cannot be detected. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elevator traction rope detection device, which can facilitate inspection and improve diagnosis a...
