Abstract

The invention discloses a device and a method for detecting and evaluating defects of an elevator composite steel belt. The device comprises an armature connected with a handle, two permanent magnets, a guide wheel, a clamping tool and a magnetic flux leakage testing sensor, wherein the permanent magnets are connected with the side faces, close to a traction steel belt of a detected elevator, at two ends of the armature respectively so that a closed loop is formed in a magnetic field, and the permanent magnets are connected with pole shoes; the guide wheel is connected with the armature, a guide groove matched with the traction steel belt of the detected elevator is formed in the guide wheel, and limiting is formed by the left and right side walls of the guide groove and two sides of the traction steel belt of the detected elevator; the clamping tool is connected with the armature, and is fixed to a surrounding rail during detection; and the magnetic flux leakage testing sensor is connected with the armature, and is used for receiving a leakage magnetic field generated when metal steel wires inside the traction steel belt of the detected elevator are lost or broken. The detection device is carried through the handle and is handheld for detection, and inspection of front-line operators in elevator inspection organizations and elevator maintenance units for the traction steel belt is facilitated.

Description

Technical field [0001] The invention relates to elevator detection technology, in particular to elevator traction steel belt detection technology. Background technique [0002] The traction steel belt is one of the most important parts of the elevator traction system. It carries all the weight of the car and the counterweight. It drives the elevator car up and down by friction with the traction sheave groove. It is a very important part of the elevator. Therefore, the safety of traction steel belt is an important guarantee for elevator safety. [0003] As a new elevator traction medium, the main function of composite steel belt is to replace the work of traction steel rope. Because of its innovative design and good energy-saving effect, it has been recognized by more and more users, and its market share has increased rapidly. As an important part of the elevator load and drive, the composite steel belt directly affects the safe operation of the elevator. Therefore, it needs to be...
