[0002] With the continuous development of modern urban construction, elevators have become an indispensable means of transportation in people's lives. Elevators refer to permanent transportation equipment that serves several specific floors in a building and whose cars run on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. When the elevator is in operation, the wire rope connects the traction box and the car, and is wound around the guide wheel and the traction wheel respectively. The motor drives the traction wheel to rotate through the speed change of the reducer, and the lifting and lowering movement of the counterweight and the car is completed through the friction between the traction wheel and the wire rope. The wire rope may be damaged when the elevator is used for a long time. It is necessary to use flaw detection equipment to detect it.
[0003] The elevator steel bar flaw detector is an instrument used to detect elevator steel bar damage. Its working principle is to quantitatively detect surface or internal broken wires in the wire rope and changes in the total metal cross-sectional area in the wire rope cross section caused by wear, rust, rope diameter, etc. through the weak magnetic principle. When inspecting the steel bar, only damage on the steel bar can be detected, and the approximate damage location is displayed through the data, and the specific damage location needs to be found by the staff.
