Description

Technical Field

[0001] This utility model relates to the field of elevator equipment technology, and in particular to a steel wire rope support roller for inclined elevators. Background Technology

[0002] An inclined elevator is a transportation device whose running trajectory is at a certain angle to the horizontal plane, used to transport passengers or goods. The traction steel wire ropes and compensating steel wire ropes of an inclined elevator are arranged at an angle along the running trajectory, and the steel wire ropes sag under their own weight. If the amount of sag is not limited, the steel wire ropes will collide, rub against, or even snag on the shaft components. Therefore, steel wire rope support rollers are usually installed at intervals below the projection of the steel wire ropes.

[0003] The wire rope roller assemblies currently in use are typically made of stainless steel pipes or rubber-coated rollers, with steel baffles on both sides.

[0004] When the roller assembly supports the wire rope, the wire rope will deviate due to the twist of the wire rope and the friction between the wire rope and the roller. This will cause the wire rope to rub against the steel baffle, which will accelerate the wear of the wire rope and the baffle and affect the service life of the wire rope and the roller. Utility Model Content

[0005] The purpose of this utility model is to provide a wire rope support roller for inclined elevators to solve the problem of wear between the wire rope and the baffle plate in existing wire rope support rollers.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a steel wire rope support roller for an inclined elevator, comprising:

[0007] The roller body has symmetrically arranged side protrusions on both sides. The diameter of the roller body gradually decreases from the end face to the middle. The surface of the roller body is a concave arc surface that is high on both sides and low in the middle.

[0008] The roller shaft is located inside the shaft hole of the roller body;

[0009] The bearing is sleeved on the roller shaft and is located in the shaft hole of the roller body.

[0010] As a further description of the above technical solution:

[0011] The roller body includes an inner support tube and a polyurethane wheel body. The roller shaft passes through the inner support tube, and the polyurethane wheel body is fitted onto the surface of the inner support tube.

[0012] As a further description of the above technical solution:

[0013] The inner support tube is made of steel.

[0014] As a further description of the above technical solution:

[0015] The inner wall of the inner support tube is provided with several circumferentially arranged support bars, which have a spiral structure.

[0016] As a further description of the above technical solution:

[0017] A shaft retaining ring is provided on one side of the bearing, and a hole retaining ring is provided on the opposite side. The shaft retaining ring is engaged in the first annular groove on the support roller shaft, and the hole retaining ring is engaged in the second annular groove of the inner support tube.

[0018] As a further description of the above technical solution:

[0019] The retaining ring for the shaft is an elastic retaining ring.

[0020] As a further description of the above technical solution:

[0021] The retaining ring for the hole is an elastic retaining ring.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] 1. In this utility model, the surface of the wire rope support roller is a concave arc surface that is high on both sides and low in the middle. This reduces the deviation of the wire rope caused by the twist of the wire rope and the friction between the wire rope and the support roller, thereby improving the guiding effect of the wire rope and reducing wear. At the same time, the side protrusions symmetrically arranged on both sides of the support roller body prevent the wire rope from coming off.

[0024] 2. In this utility model, the support roller body is made by casting a polyurethane layer onto the outside of a steel inner support tube. The steel inner support tube provides support, ensuring that the support roller body does not cause wear on the wire rope while providing sufficient support strength. Attached Figure Description
