Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an elevator rope cleaning device.

[Conventional technology]

FIG. 4 is a schematic diagram showing a conventional elevator rope cleaning device disclosed in, for example, Japanese Utility Model Application No. 59-8978. In the figure, 1 is the sheave of the hoist, 2 is the deflection wheel, and 3 is the A rope for suspending a car and a counterweight (both not shown); 4 is a cleaning device for the rope 3; 5 is an electric motor of the cleaning device 4; 6 is a driving sprocket attached to the electric motor 5; 7 is a chain, 8 and 9 are driven sprockets, and 10 is a pair of circular brushes that are rotatably supported by the sprockets 8 and 8 and are arranged to sandwich the rope 3. Figure 5 shows rope 3 and brush 10,
10 is an enlarged view of FIG.

Next, the operation will be explained. The sprocket 6 and chain 7 are driven by the electric motor 5, and the brushes 10, 10 are rotated in the same direction. This cleans the surface of the rope 3. That is, the rope 3 is used for corrosion prevention or to improve flexibility.
The rope is impregnated with oil, and oil oozes out from the rope surface. Therefore, dust in the air adheres to the surface of the rope 3. Particularly in outdoor elevators, dust adheres to the rope surface and causes significant wear on the sheave 1 and the rope 3. However, the rope cleaning device 4 removes the dust to prevent shortening of the life of the sheave 1 and rope 3. ing.

Fig. 6 shows another example of a conventional rope cleaning device, in which reference numeral 11 denotes a mounting base provided on a hoist;
Reference numeral 2 denotes a mount fixed to the mount 11 with bolts 13, and 14 a pair of flat brushes connected to the mount 12 with bolts 15. In such a case, 1
The rope 3 rubs between the pair of flat brushes 14, 14 to remove dirt.

[Problem that the invention seeks to solve]

Since the conventional rope cleaning device is constructed as described above, the brushes 10 and 1 are connected to the rope 3.
The contact area of 4 is constant, and as a result, when a wear groove A is formed in the rope contact area of the brush as shown in Fig. 7, the cleaning ability of the rope decreases significantly and the brush must be replaced with a new one. . In addition, the rope cleaning device shown in FIG. 4 requires a complicated mechanism to drive the brush, resulting in high costs.

Furthermore, in the conventional devices, no consideration was given to moisture adhering to the rope.

This invention was made to solve the above-mentioned problems, and it is possible to extend the service life of the rope without reducing its cleaning ability even when the brush is worn out, and to remove moisture sufficiently. The object of the present invention is to obtain a rope cleaning device according to the present invention.

[Means to solve the problem]

In order to achieve the above object, in this invention, mounting brackets are erected on the mounting base of a hoisting machine, etc., facing each other so as to sandwich the rope passing through the mounting base, and each mounting base is provided with an elastic body. The brush tips of the flat brushes attached through the ropes are brought into elastic sliding contact with the rope, and the plurality of raised bristles of the opposing flat brushes are arranged in a staggered pattern on the left and right sides, and on the top of each of the mounting brackets. It is characterized by having a water cutter made of felt or the like that comes into sliding contact with the rope mentioned above.

[Effect]

According to this invention, as described above, since the flat brush is in elastic sliding contact with the rope surface via the elastic body, the contact with the rope is always flexible and there is little wear and tear, and the raised portions of the brushes are mutually opposed to each other. Because they are arranged in a zigzag pattern, there is no risk of the left and right raised parts coming into contact with each other during wear, making it durable for long-term use.Also, the brush removes foreign matter and the water drainer eliminates moisture adhesion, making it a good rope. The cleaning effect can be demonstrated.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of the rope cleaning device. Reference numeral 16 denotes a pair of U-shaped fittings, which are connected to the hoisting machine's mounting base 11 with bolts 13, and attached to the part of the fittings 16 facing the rope 3. The opening 16a is open.
Reference numeral 17 denotes a brush mount, which is held by a bolt 18 and a nut 19 via a spring 20 which is an elastic body. Reference numeral 21 denotes a flat brush which is supported by the brush mount 17 via a pedestal 21a and whose raised portions are arranged in a staggered pattern alternately on the left and right sides facing each other. ing. Reference numeral 22 denotes a presser foot having teeth 22a at one end, and the other end of the presser foot 22 is fixed to the upper part of the fitting 16 with a bolt 23. 24 is a drainer made of felt or the like, and the teeth 22a of the presser foot 22
This drainer 24 pinches the rope 3 from the left and right sides and closes the gap.

In the rope cleaning device of the present invention configured as described above, dust adhering to the surface of the rope 3 is removed by the brush 21. However, since this brush 21 is automatically fed out to the rope side by the spring force of the spring 20, the rope 3 and the brush 21 are always in contact with each other.
As a result, it can be used for a long period of time without reducing its cleaning ability. Further, in an outdoor elevator, when it rains, rainwater adheres to the rope 3, and water splashes are generated at the brush sliding portion of the rope and scattered into the machine room. Therefore, in this invention, the drainer 24 can prevent the particles from scattering upward.
By using felt etc. as the material for the drainer 24, the rope 3
By pressing it against the surface of the rope, it will naturally deform and come into close contact with the rope surface.

In the above embodiment, the brush 21 is brought into elastic contact with the rope 3 by the spring 20, but as shown in FIG. 2, rubber 25 may be used as the elastic body. In the figure, 26 is a bolt that supports one side of the rubber 25 on the mounting bracket 16, and 27 is a brush 21.
This bolt supports the pedestal 21a on the other side of the rubber 25. By bringing the brush 21 into elastic contact with the rope 3 in such a manner that compressive force is applied to the rubber 25, the brush 21 is fed out against wear, similar to the embodiment described above.

FIG. 3 shows another embodiment. Reference numeral 28 denotes a frame whose lower end is rotatably supported by a pin 29 on the bearing 16b of the mounting bracket 16. The brush 21 is attached to the frame 28 via a pedestal 21a via a bolt 30. It is installed with. Numeral 31 is a bolt that connects the mounting bracket 16 and the upper part of the frame 28 from behind the frame via a spring 32, and the spring force of the spring 32 causes the brush 21 to come into elastic contact with the rope 3. With this configuration, the brush 21 can be fed out toward the rope by the spring force when the brush 21 is worn out.

In the embodiments shown in FIGS. 2 and 3, the water cutter 24 provided on the top of the mounting bracket 16 is not shown.

〔Effect of the invention〕

As described above, according to the present invention, the flat brush always makes flexible and elastic sliding contact with the rope surface, resulting in less wear, and the raised portions are staggered on the left and right sides, so even when worn, the raised portions do not come into contact with each other and can be used for a long period of time. In addition, it can remove moisture along with foreign substances by draining, and has a good cleaning effect.
