Description

Hairbrush cleaning device for preventing foreign matters on elevator pulley

Technical Field

The utility model relates to a device of foreign matter is prevented to elevator pulley, especially a brush cleaning device of foreign matter is prevented to elevator pulley.

Background

A wire rope used for parts such as a speed governor and a traction main machine of an elevator is used for traction, and the wire rope is guided by a pulley. During the operation of the steel wire rope, lubricating oil is usually added to the steel wire rope before use in order to reduce wear, and during the use, the lubricating oil on the surface of the steel wire rope is adhered and accumulated to form oil sludge due to dust and the like. In the running process of the elevator, dust in a shaft and oil sludge on the surface of a steel wire rope easily enter a rope groove of a pulley, so that the steel wire rope of the elevator jumps radially, and the elevator car vibrates abnormally and is unstable. The existing device for preventing foreign matters from entering the pulley generally adopts single-sided bristles to block, has small contact area with a steel wire rope, not only has a common cleaning effect on the steel wire rope, but also can easily enter a rope groove of the pulley by the cleaned foreign matters and external impurities, and has a common foreign matter prevention effect.

Therefore, the existing device for preventing the foreign matters on the elevator pulley has the problems that the cleaning effect on the steel wire rope is general, and the foreign matters can not be completely prevented from falling into the pulley.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a foreign matter is prevented to elevator pulley brush cleaning device. The utility model has the characteristics of the full aspect prevents that the foreign matter from dropping in the pulley, improving to wire rope's cleaning action, still improve factor of safety.

The technical scheme of the utility model: the utility model provides a foreign matter is prevented to elevator pulley brush cleaning device, includes the relative U-shaped mounting bracket that sets up of a pair of notch, and the side that two mounting brackets are relative all is covered with the brush hair, and one of them mounting bracket passes through the mount and installs in the wheel casing top of pulley, and the wire rope on the pulley passes and contacts with the brush hair from between two mounting brackets.

In the hairbrush cleaning device for preventing foreign matters on the elevator pulley, the end side edges of the two mounting frames are respectively provided with the connecting page, and the two connecting pages are connected through the bolt.

In the above-mentioned brush cleaning device for preventing foreign matters from being removed from the elevator pulley, the length of the brush is consistent with the width of the mounting frame.

In the hairbrush cleaning device for preventing the foreign matters on the elevator pulley, the fixing frame is provided with the long hole, and the length direction of the long hole is perpendicular to the length direction of the steel wire rope.

In the hairbrush cleaning device for preventing the foreign matters on the elevator pulley, the end parts of the hairbrush are wrapped with the wear-resistant ends.

Compared with the prior art, the utility model discloses a mounting bracket of two symmetries is assembled, the full brush hair of equipartition in two mounting brackets, wire rope passes through between two mounting brackets, closely wraps up by the brush hair, can effectively clean wire rope, and prevent rocking of wire rope, improve elevator operating stability, and area of contact is big between brush hair and the wire rope, it is tight to protect, can also prevent foreign matters such as external dust from falling the grooving of rope and pulley in the aspect of the whole aspect, guarantee the cleanliness factor of pulley, guarantee the stability of elevator operation.

And install this device in the top of protection casing, not only play the reinforcement effect to the protection casing, can also prevent that the staff from stretching into inside the pulley by mistake, avoid causing the incident. The elevator has the advantages of simple overall structure, direct installation on the existing elevator, convenient use and low cost.

Therefore, the utility model has the characteristics of the full aspect prevents that the foreign matter from dropping in the pulley, improving to wire rope's cleaning action, still improve factor of safety.

fig. 3 is a schematic view of the construction of a steel cord.

The labels in the figures are: 1. a mounting frame; 2. brushing; 21. a wear end; 31. a fixed mount; 32. a connection page; 33. a long hole; 4. a steel cord.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples

As shown in fig. 1-3, a brush cleaning device for preventing foreign matters on an elevator pulley comprises a pair of U-shaped mounting frames 1 with opposite notches, bristles 2 are fully distributed on opposite side surfaces of the two mounting frames 1, one of the mounting frames 1 is mounted above a wheel cover of the pulley through a fixing frame 31, and a steel wire rope 4 on the pulley passes through the two mounting frames 1 and contacts with the bristles 2.

The end side edges of the two mounting frames 1 are provided with connecting leaves 32, and the two connecting leaves 32 are connected through bolts. The installation and the dismantlement are convenient.

The length of the brush hairs 2 is consistent with the width of the mounting frame 1.

The fixing frame 31 is provided with a long hole 33, and the length direction of the long hole 33 is perpendicular to the length direction of the steel wire rope 4. The setting of long type hole 33 for mounting bracket 1 can be along wire rope 4's radial adjustment, thereby can be 4 wire rope 4's position parcel more comprehensively, improves the guard action to the pulley.

The end parts of the brush hairs 2 are wrapped with wear-resistant ends 21.

The mounting bracket 1 of two symmetries is assembled, and the brush hair 2 is filled to the equipartition in two mounting brackets 1, and wire rope 4 passes through between two mounting brackets 1, is closely wrapped up by brush hair 2, and when the car operation, brush hair 2 takes place relative motion with wire rope 4 and can effectually give wire rope 4 cleanness to block the foreign matter, prevent that the foreign matter from entering into the race, guarantee the cleanliness factor of pulley, guarantee the stability of elevator operation.

Set up wearing end 21 and wire rope 4 contact at the tip of brush hair 2, wearing end 21 can be rubber or nylon materials for when the elevator operation, reduce the noise that wire rope 4 produced with the contact of brush hair 2 when moving, improve wire rope 4's mobility stability, still reduce the wearing and tearing to brush hair 2, if wearing end 21 damages, can sheathe wearing end 21 again, used repeatedly, extension brush hair 2's life.

The part of the utility model not detailed is prior art.
