DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rail cleaning device for guiding an elevator car and the like.

[0002]

2. Description of the Related Art FIG. 3 is a view showing an installation state of an elevator incorporated in a bridge girder of a bridge connecting a mainland and an island.
As shown in FIG. 3, for example, an elevator 1 that operates on the ninth floor from 1F to 9F is incorporated in a bridge, and the 4F, that is, the 4th floor is formed on the road on which the automobile runs.
Exhaust gas accompanying the traveling of the automobile is emitted to the outside via the hoistway of the elevator 1 as shown by an arrow 5. For this reason, as shown in FIG. 4, the deposits 7 containing components in the exhaust gas are easily attached to the guide rails for guiding the car and the like of the elevator 1. Such deposits 7 cause the car to vibrate when the car is moved up and down, and give passengers of the car a discomfort. Therefore, conventionally, the maintenance staff uses the spatula 8 or the like for the guide rail 6 every predetermined period.
Attachments attached to are manually removed.

[0003]

As described above, conventionally, the deposit 7 containing components in the exhaust gas attached to the guide rail 6 is manually removed. Since the total length is long and high enough to correspond to the total length of the hoistway, for example, the ninth floor, it is difficult to perform the work, and improvement in efficiency cannot be expected. In addition, since the removal work is required at a high place, the work must be performed carefully.

The present invention has been made in view of the above-mentioned circumstances in the prior art, and has as its object to remove deposits containing components in exhaust gas attached to guide rails without requiring manual operation by maintenance personnel. It is an object of the present invention to provide a guide rail cleaning device that can perform the cleaning.

[0005]

In order to achieve this object, the present invention relates to a guide rail cleaning apparatus for cleaning a guide rail for guiding an elevating body which moves up and down in a hoistway. A cleaning tool is provided for cleaning the guide rail in contact with the rail, and the cleaning tool includes an abrasive.

In the present invention thus constructed, when the elevating body, for example, the car, is raised and lowered, the adhering matter on the guide rail can be scraped off by the abrasive of the cleaning tool provided on the elevating body, and maintenance personnel The guide rail can be cleaned without any manual work.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a view showing the overall configuration of an embodiment of the present invention, and FIG. 2 is a perspective view showing a cleaning member included in a cleaning tool provided in this embodiment.

In FIG. 1, reference numeral 11 denotes one of a pair of car guide rails installed in a hoistway, and reference numeral 12 denotes a crosshead located on the roof of the car. Brackets 13 and 14 are fixed to the crosshead 12 by bolts 15 and the like. The bracket 13 holds a roller 16 that rolls in contact with the side surface 17 of the guide rail 11.
A roller 19 that rolls while contacting the front end face 18 of the guide rail 11 is held. The car is raised and lowered by lifting and lowering a rope (not shown).
The guides 6 and 19 are guided by the guide rail 11 so that the ascending and descending can be performed smoothly. Although only one guide rail 11 is illustrated in FIG. 1, similar brackets, rollers, and the like are provided on the other guide rail side.

In FIG. 1, reference numeral 20 denotes a mounting base fixed to the bracket 13, for example, and reference numeral 21 denotes a cleaning tool. In this embodiment, the mounting base 20 and the cleaning tool 21 and the like are used. The mounting base 20 is integrally fastened to the bracket 13 by, for example, bolts 22. The cleaning tool 21 includes a holder 23 and a cleaning member 24. The lower portion of the holder 23 is provided with a flange 25 that extends laterally. This flange 25 is placed on the mounting base 20. A leaf spring 26 is disposed on the flange 25, and the flange 25 is clamped by the leaf spring 26 and the mounting base 20 by tightening a thumb screw 27 that penetrates the leaf spring 26 and is screwed to the mounting base 20. Fixed to Further, as shown in FIG. 2, the cleaning member 24 described above is a nonwoven fabric 2 containing an abrasive.
8 and a sponge rubber 29 disposed on the nonwoven fabric 28
And a rigid support member 30 made of, for example, an aluminum plate and disposed on the sponge rubber 29. These cleaning members 24 are indicated by broken lines 3 in FIG.
At portions 1 and 32, the nonwoven fabric 28 is bent in a U-shape so that the non-woven fabric 28 is on the inside and the support member 30 is on the outside, and fitted into the U-shaped mounting portion 23 of the holder 23 described above. That is, the nonwoven fabric 28 is disposed so as to cover the side surface 17 and the front end surface 18 of the guide rail 11. In addition, the mounting base 20,
A combination of the holder 23, the cleaning member 24, and the like is provided on one side of the crosshead 12 so as to face another guide rail (not shown).

In the present embodiment, in a normal operation state, for example, the thumb screw 27 is loosened and the holder 23 including the cleaning member 24 is removed from the mount 20. That is, the mounting base 20 is fixed to the crosshead 12, and a state where only the leaf spring 26 and the thumb screw 27 are provided on the mounting base 20 is left.

When cleaning the guide rail 11, the holder 23 is arranged so that the nonwoven fabric 28 of the cleaning member 24 contacts the guide rail 11, the flange 25 is sandwiched by the leaf spring 26, and the thumb screw 27 is tightened and fixed. . In this state, for example, the car for one round trip is raised and lowered. As a result, even if the surface of the guide rail 11 has the attached matter 7 containing the components in the exhaust gas, the surface of the guide rail 11 can be cleaned by the abrasive contained in the nonwoven fabric 28, and the surface of the guide rail 11 can be cleaned.

According to the present embodiment, desired attachments 7 can be cleaned simply by mounting the holder 23 including the cleaning member 24 on the mounting base 20 and raising and lowering the car, thereby improving the efficiency of this cleaning operation. be able to.

[0014]

As described above, according to the present invention, it is possible to carry out the cleaning of the deposits containing the desired exhaust gas components without the need for manual operation of a person as the car is raised and lowered. Can be improved.
