Description

Technical Field

[0001] This utility model relates to the field of elevator traction sheave wear detection technology, and in particular to an elevator traction sheave wear detection device. Background Technology

[0002] The elevator traction sheave is an important component of the elevator system, used to transmit power and lift the elevator car. During use, the traction sheave may experience some wear and malfunctions. In order to slow down the wear of the traction sheave, regular inspection, lubrication and maintenance are required to ensure the reliable operation of the elevator system for a long time.

[0003] A search revealed that patent number "CN220011762U" mentions "an elevator traction sheave wear detection device, including a detection platform, a bracket fixedly connected to the top of the detection platform, a detection component mounted on the surface of the bracket, the detection component including several measuring columns, the measuring columns slidably mounted on the bracket, an annular protrusion fixedly connected to the lower side wall of the measuring column, and a spring sleeved on the outside of the measuring column; this utility model uses an electric telescopic rod to drive a push rod to rise, thereby quickly pulling up the measuring column as a whole. Compared with the prior art, it is convenient to use and improves efficiency." The device boasts high detection efficiency and allows for convenient placement of the traction sheave body on the testing platform. The measuring column, propelled by a spring, is inserted into the groove of the traction sheave body for testing. The depth of the measuring column's descent is read via a graduated groove, thus determining the depth of the groove and the degree of wear. While this device detects wear within the groove through the vertical displacement of the measuring column, it requires direct contact with the groove. During the rotation of the traction sheave, this direct contact can easily cause wear to the inner wall of the groove. Furthermore, the measuring column's detection is incomplete, failing to detect hidden cracks within the traction sheave groove.

[0004] Therefore, we provide an elevator traction sheave wear detection device to solve the above problems. Utility Model Content

Then, the testing begins. First, the electric push rod 5 is moved downward by the control panel 12 until the ultrasonic probe 7 and the drain pipe 82 enter the groove of the elevator traction sheave 3. Second, the first motor 2 is controlled by the control panel 12 to drive the elevator traction sheave 3 to rotate at a constant speed. At the same time, the electric push rod 831 is controlled by the control panel 12 to work, so that the coupling agent inside the loading box 8 is...
