Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings.
[0025] Such as Figure 1-3 As shown, a counterweight traction sheave of an elevator includes a wheel body 1, and the wheel body 1 is provided with a plurality of rims 2 symmetrical along the center line of the wheel body 1, and a rim 2 is formed between two adjacent rims 2. The rope groove 3, the wheel body 1 is provided with a number of displacement blocks 4 that can reciprocate along a straight line and pass through the rim 2, and the displacement block 4 is provided with a straight line that can be made close to or far from the rope groove 3. The reciprocating anti-slip wear-resistant sleeve assembly 5, the anti-slip wear-resistant sleeve assembly 5 corresponds to the position of the rope groove 3, the described wheel rim 2 is provided with a wear-resistant sleeve drive member 6, and the described wear-resistant sleeve The driving member 6 is connected with the ant...

The invention belongs to the technical field of traction wheels, and particularly relates to an elevator counterweight traction wheel. The elevator counterweight traction wheel comprises a wheel body, the wheel body is provided with a plurality of wheel rims which are symmetrical along the center line of the wheel body, a rope groove is formed between every two adjacent wheel rims, and a plurality of displacement blocks which can do reciprocating motion along the straight line and penetrate through the wheel rims are arranged in the wheel body. Each displacement block is provided with an anti-skid wear-resistant sleeve assembly capable of doing linear reciprocating motion along the end close to or away from the rope groove, each anti-skid wear-resistant sleeve assembly corresponds to the rope groove in position, and the wheel rims are provided with wear-resistant sleeve driving pieces. By arranging the detachable anti-skid wear-resistant ring and the wear-resistant sleeve base, a steel wire rope and the detachable anti-skid wear-resistant ring are wound in a contact mode, it is guaranteed that in the operation process of the steel wire rope, deformation of the groove profile of the traction wheel is avoided, wear to the groove profile is reduced, and the service life of the traction wheel is prolonged. Meanwhile, maintenance personnel can conveniently check the losses of the detachable anti-skid wear-resistant ring, and the detachable anti-skid wear-resistant ring can be replaced in time.
Description
technical field [0001] The invention belongs to the technical field of traction wheels, and relates to an elevator counterweight traction wheel. Background technique [0002] As a common vertical lifting tool, traction elevators are widely used in large commercial buildings or office buildings. Compared with hydraulic elevators, traction elevators have the advantages of high transmission height, high acceleration, and rapid lifting. The use range of traction elevators is also very large. widely. As an important part of the elevator, the traction sheave is also called the traction sheave or the driving sheave; it is the device for the elevator to transmit the traction power. During the operation of the traction sheave, the groove of the traction sheave will wear more seriously with the increase of the service time, which is easy to cause deformation, and the service life of the traction sheave is shorter. [0003] In order to overcome the deficiencies of the existing techno...
