Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a guide rail lubrication device for an elevator that refuels a guide rail that guides traveling of a moving body such as a car or a counterweight.

[0002]

[Prior Art]

 Generally, a moving body such as an elevator car or a counterweight is provided with an engaging device, and the engaging device is fitted to a guide rail to guide the traveling of the moving body along the guide rail. A guide rail lubrication device for supplying lubricating oil to the fitting surface between the guide rail and the engagement device is, as described in Japanese Utility Model Laid-Open No. 62-132084, a case of the engagement device attached to a moving body, It was constituted by an oil-impregnated member housed in this case. Then, the lubricating oil in the oil-impregnated member was supplied to the guide rail.

[0003]

[Problems to be solved by the device]

 In the conventional guide rail lubrication system described above, the oil-impregnated member was attached to the case by the vertical stopper and the fixing screw, so the fixing screw must be removed each time the oil-impregnated member is replaced or inspected, which complicates the work. It also took time.

An object of the present invention is to provide a guide rail lubrication device for an elevator that allows easy replacement and inspection of oil-containing members in a short time.

[0005]

[Means for Solving the Problems]

 For the above purpose, the engaging device attached to the moving body is engaged with the sliding surface of the guide rail, the moving body is moved along the guide rail, and the oil-impregnated member unit can be attached to and detached from the case of the engaging device. In the elevator guide rail lubrication device in which the oil-impregnated member unit is used to supply oil to the sliding surface of the guide rail, the oil-impregnated member unit and the oil-impregnated member that abut against the sliding surface are provided. The oil-impregnated member is formed from a U-shaped plate frame that supports the oil-impregnated member from behind. A lower support for supporting the lid, a lid provided on the upper part of the case and having a bent U-shaped plate end portion for covering the oil-impregnated member unit, and a means for attaching and fixing the lid to the case. It is achieved by.

[0006]

[Action]

 According to the present invention, as described above, the lower end of the case is projected inward to serve as a lower support, and the upper end is provided with a lid for bending the U-shaped plate end that covers the oil-impregnated member unit. For inspection, the upper lid can be pulled up and taken out from the oil-impregnated member case, so replacement and inspection work can be performed easily.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of the guide rail lubricating device, FIG. 4 is a sectional view of the guide rail lubricating device, and FIG. 5 is a side view of FIG. The lubricating device in contact with the sliding surface of the guide rail 1 in the figure comprises an oil-impregnated member unit 10. The engaging device is composed of a mounting portion 3 bent at a right angle by a reinforcing member 11 and a cross-section C-shaped case 4 provided on the outside of one surface of the mounting portion 3. An oil-impregnated member unit 10 having a U-shaped cross section, which is supported from behind by a plate frame 9, is fitted in the recess of the case 4, and is fixed by a lid 6A fitted in the upper part of the case 4. As shown in (A) in the figure, a pawl 13 is provided inside the lid 6A, and a plurality of holes are provided above the case 4 corresponding to the positions of the pawls 13 so that the pawls 13 can be fitted with each other. The engaging device 2 is configured by the above. This pawl 13 prevents the lid 6A from coming off due to the vertical movement of the elevator. However, when the oil impregnating member 10 is replaced, the lid 6A can be easily detached from the case 4 by unfolding the lid 6A to the left and right with an operator's hand. When the lid 6A is attached, the hole 12 and the pawl 13 are fitted by simply aligning the lower surface of the lid 6A with the upper end of the case 4 and sliding the lid 6A as shown by the mark in the figure. 6A is fixed to the case 4. Further, the oil impregnating member 7 and the plate frame 9 are bonded and integrated.

The plate frame 9 of the oil-impregnated member unit 10 may be made of any material as long as it has a relatively large deformation resistance and is effective for imparting a U-shape to the oil-impregnated member 7. Further, Kapok fiber or the like can be used as the material of the oil-containing member 7.

In the present embodiment, when a maintenance person enters the hoistway of the elevator and sees the lubricating state of the sliding surface of the guide rail 1 and determines that the lubricating oil needs to be replenished or replaced, a new The oil-impregnated member unit 10 is prepared, and the lid 6A is removed from the case 4 by the procedure described above. Next, the old oil-impregnated member unit 10 is pulled out from the case 4, a new unit 10 is mounted, and then the lid 6A is slid and fixed to the case 4. The newer unit 10 is fixed to the case 4 by this. The newly attached oil-impregnated member unit 10 is in contact with the sliding surface of the guide rail 1, and supplies oil to the sliding surface as the moving body (car or balance weight) 8 moves.

Next, another embodiment of the present invention will be described.

In another embodiment shown in FIG. 2, a lid 6B having a shape similar to that of the above-described embodiment is rotatably attached to a case 4 by using a hinge 14 to form an engaging device 2. ..

The lid 6B is fixed in the same manner as in the above-described embodiment, and the pawl 13 provided in the lid 6B and the hole 12 provided in the case 4 are fitted to each other so that the oil-impregnated member unit 10 does not come off. Is becoming

Next, the embodiment shown in FIG. 3 will be described.

The lid 6C has an end portion of a U-shaped plate bent, and fixing pieces 16 are provided at the lower part of the bent end portion on both sides centering on the opening of the U-shaped plate. Further, the upper end portion of the case 4 is also provided with a fixing piece 17 similar to the above-mentioned fixing piece 16 at positions facing each other. The lid 6C is rotatably attached to the case 4 by a hinge 14 and constitutes the engaging device 2.

In this embodiment, after the oil-impregnated member unit 10 is mounted on the case 4, the lid 6C is closed and the bolts 15 are passed through the holes provided in the fixing pieces 16 and 17 to fix the oil-impregnated member unit. It goes without saying that the use of the wing nut for the nut used for the bolt 15 makes it easier to replace the oil-containing component unit 10.

As described above, according to the present embodiment, the oil-impregnated member unit 10 can be replaced very easily and in a short time, and since the oil-impregnated member unit 10 of the guide rail lubrication device is used, the guide rail surface is not changed. It is possible to prevent excessive supply of oil, and reduce the consumption of lubricating oil and the labor of maintenance personnel.

[0018]

[Effect of the device]

 As described above, according to the present invention, at the time of replacement or inspection, the upper lid can be pulled up and taken out from the oil-impregnated member case, so that replacement or inspection work can be easily performed. effective.
