Description

Technical Field

[0001] The present invention relates to the technical field of elevator detection, and more particularly to a convenient measuring device for the wear of an elevator traction wheel. Background Art

[0002] In the prior art, the traction sheave is a rope sheave on a traction machine, also called a traction rope sheave or a driving rope sheave. Figure 1 As shown in the figure, it is a device for transmitting traction power of an elevator, which transmits power by using the friction between the traction wire rope and the rope groove on the traction wheel rim. After the traction wheel is used for a long time, its wheel groove will be worn. When the wear reaches a certain range, the traction wheel needs to be replaced to avoid elevator accidents. However, the existing technology for detecting the wear of the traction wheel has the following shortcomings.

[0003] The traditional traction sheave wear detection device can only detect the wear amount perpendicular to its axial direction. However, due to installation errors or severe wear of the bearings at both ends of the traction sheave, the traction sheave will tilt, causing the steel wire to deviate toward one side wall of the traction ring groove and the bottom surface of the ring groove during the rotation of the traction sheave, resulting in offset wear. The offset wear cannot be detected by the traditional traction sheave wear detection device alone, which poses certain safety hazards.

[0004] Therefore, how to provide a new convenient measuring device for the wear of the elevator traction wheel, which can detect the wear of the traction ring groove and follow the wear trajectory of the traction ring groove, is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In view of this, the present invention provides a convenient measuring device for the wear of an elevator traction wheel, aiming to solve the technical problem that the above-mentioned traditional traction wheel wear detection device can only detect the wear perpendicular to its axial direction, and cannot detect the wear at other positions on the bottom surface of the ring groove caused by the deviation of the steel wire.

[0046] More specifically, the roller 25 includes a circular plate 252 and a ring 251. The circular plate 252 is provided with a rotating hole 253 along its axial direction. The axial surface of the pin 26 is rotatably connected to the rotating hole 253. The ring 251 is a circular ring body with a circular cross-section, which is coaxially arranged with the circular plate 252, and its inner surface is tightly connected to the outer wall of the circular plate 252.

[0047] More specifically, the diameter of the circular cross section of the annular ring 251 is twice the thickness of the circular plate 252 .

[0059] In some embodiments, the second positioning surface 42 contacts and abuts against a side wall surface of the traction ring groove 91 near one end of the traction wheel 9 .

[0060] In other embodiments, both the positioning surface 1 41 and the positioning surface 3 51 are in contact with the traction wheel 9 via a plurality of guide wheels to prevent scratches on the wheel surface of the traction wheel 9 .
