Description

Technical Field

[0001] The utility model belongs to the technical field of elevator maintenance, and particularly relates to an elevator wire rope lubrication device. Background Art

[0002] Elevator wire rope is a tool that transmits power by friction. It works frequently and runs at a high speed, which requires good friction between the wire rope and the traction wheel. Since the wire rope is composed of multiple wires, under working conditions, wire rope grease can reduce the friction between the wires while ensuring the friction between the wire rope and the traction wheel, effectively extending the service life of the wire rope. Therefore, it is necessary to lubricate and maintain the wire rope.

[0003] The Chinese patent with the publication number CN214141136U discloses a lubrication device for elevator wire ropes. The lubrication assembly on the base is slid to the wire rope position. When the lubrication assembly moves to the appropriate position, the lubrication tube wraps the wire rope. The wire rope rubs against the buffer layer during operation, and the lubricating oil on the buffer layer lubricates the wire rope to achieve the lubrication effect. It can be lubricated during the operation of the elevator. However, during the lubrication process of the wire rope, the grease on the wire rope may form sludge on the wire rope. On the other hand, when the wire rope is too grease, it may also cause brake failure and other phenomena. Therefore, during lubrication, it is necessary to lubricate the wire rope and avoid excessive contact between the lubricating oil and the wire rope. Utility Model Content

[0004] The utility model aims to overcome the defect of excessive lubrication of steel wire ropes in the prior art and provide a steel wire rope lubrication device for elevators.

[0005] The utility model provides an elevator wire rope lubrication device, comprising a mounting back plate, which is fixedly connected to the inner wall of the elevator shaft by bolts, two sets of triangular brackets are symmetrically arranged on the side of the mounting back plate, a slide rail is arranged on the top of the triangular bracket, a lubrication box is arranged on the top of the slide rail, the lubrication box is provided with a slide groove, the slide groove is slidably connected to the slide rail, and the wire rope runs through the lubrication box;

[0006] The lubrication box is provided with an oil storage tank for storing lubricating oil, a lubricating brush is also provided inside the lubrication box, a rotating shaft is provided on one side of the lubricating brush, a motor box is provided on one side of the lubrication box, a motor is provided inside the motor box, the motor is connected to the rotating shaft, and is used to drive the rotating shaft and the lubricating brush to rotate. When the lubricating brush rotates to a vertical downward state, the lubricating brush contacts the lubricating oil for wetting the lubricating brush, and when the lubricating brush rotates to a horizontal state and faces the wire rope, the lubricating brush contacts the wire rope for lubricating the wire rope.

[0007] A further solution is that the oil storage tank is located at the bottom of the lubrication box, and an oil filling hole and an oil drain hole are opened on the side wall of the lubrication box, and the oil filling hole and the oil drain hole are both connected to the oil storage tank.

[0008] A further solution is that the lubricating brush includes a brush row and bristles; the bristles are evenly and densely distributed on one side of the brush row, and a side of the brush row away from the bristles is fixedly connected to the rotating shaft.

[0009] A further solution is that when the lubricating brush rotates to a vertically downward position, the bristles come into contact with the lubricating oil.

[0010] A further solution is that an oil drain plate is also provided inside the lubrication box;

[0011] One side of the oil drain plate is connected to the side wall of the lubrication box, and the other side of the oil drain plate is provided with a plurality of oil drain teeth, and two adjacent oil drain teeth form an oil drain groove.

[0012] A further solution is that when the lubricating brush rotates at an angle, the bristles contact the oil drain groove to drain excess lubricating oil from the bristles.

[0013] A further solution is that the oil drain plate is at the same height as the rotating shaft and is connected to the side wall of the lubrication box away from the wire rope. When the lubrication brush rotates to a horizontal state and away from the wire rope, the bristles contact the oil drain groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model provides a lubrication brush and an oil storage tank in the lubrication box, and the lubrication brush is driven by a motor to rotate clockwise, so that the lubrication brush lubricates the wire rope after being moistened in the oil storage tank, thereby avoiding direct contact between the wire rope and the oil storage tank, and avoiding brake failure caused by excessive lubrication of the wire rope while ensuring the lubrication effect.

[0016] The utility model also provides an oil drain plate in the lubrication box. When the lubrication brush rotates, the bristles contact with and pass through the oil drain groove, and excess lubricating oil on the bristles is drained into the oil storage tank, further avoiding the phenomenon of excessive grease on the wire rope.
