DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rail lubrication device for an elevator that refuels a guide rail for guiding the traveling of a moving body such as a car or a counterweight.

[0002]

2. Description of the Related 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. The guide rail lubrication device that supplies lubricating oil to the fitting surface between the guide rail and the engagement device is
As described in Japanese Utility Model Application Laid-Open No. 62-132084, it is constituted by a case of an engaging device attached to a moving body and an oil-impregnated member housed in the case. Then, the lubricating oil in the oil-impregnated member is supplied to the guide rail.

[0003]

In the conventional guide rail lubrication device described above, the oil-impregnated member is attached to the case by the vertical stopper and the fixing screw. It had to be removed, and the work was complicated and time consuming.

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

[0005]

In order to achieve the above object, the present invention engages an engaging device attached to a moving body with a sliding surface of a guide rail, and moves the moving body along the guide rail. Then, in the guide rail lubrication device of the elevator, in which the oil-impregnated member unit is detachably provided in the case of the engagement device, and the oil-impregnated member unit is used to supply oil to the sliding surface of the guide rail,
The oil-impregnated member unit includes a oil-impregnated member in contact with the sliding surface to support the oil-impregnated member from behind, to the case
And a supporting member having a planar U-shape when stored, and the case of the engaging device projects inward at a lower end of the case, and a lower support that directly supports a lower portion of the oil-containing member, It is composed of an upper presser inserted from the back into a collar formed at the upper end of the case.

[0006]

[Function] As described above, the lower end of the case is projected inward to serve as a lower support, and the upper end is a plug-in type upper presser that is inserted into the collar from the rear side. When pulled out to the back side, it can be taken out from the oil-impregnated member case, and can be easily replaced or inspected.

[0007]

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

FIG . 1 shows an elevator guide rail according to the present invention.
FIG. 2 is a perspective view showing an embodiment of a lubricating device, and FIG.
Fig. 3 is a plan view of the guide rail lubricator, and Fig. 4 is a plan view.
It is an expansion perspective view of an oil member unit. Shown in FIG. 3 and FIG.
As described above, the lubricating device in contact with the sliding surface of the guide rail 1 is composed of the engaging device 2 having a function of holding the oil-impregnated member unit 10 and the oil-impregnated member unit 10.
The engagement device 2 is composed of a mounting portion 3 bent at a right angle by a reinforcing member 11 and a case 4 having a U-shaped cross section 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 into the recess of the case 4, and is fixed by retaining mechanisms formed at the upper and lower ends of the case 4. The retaining mechanism, FIG. 1, as shown in FIG. 2, is formed by bending a lower end of the case 4 inward, containing
Lower support 5 for directly supporting the lower part of the oil member unit 10
And an upper presser 6 formed with a groove 6A that fits into the collar 4A at the upper end of the case 4 and is inserted horizontally from behind. In addition, the upper presser 6 has a retaining claw 6
It has a disengagement piece 6C between B and the collar 4A.

[0009] containing oil section unit 10, as shown in FIG. 4,
The oil-impregnated member 7 and the oil-impregnated member 7 are supported from behind by
A support body that has a U-shaped plan when it is stored in
And other words plate frame 9 is integrally bonded. 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 in 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 this embodiment, when a maintenance person enters the hoistway of the elevator and sees the lubricating condition of the sliding surface of the guide rail 1 and determines that the lubricating oil needs to be replenished or replaced, a new oil impregnation is required. The member unit 10 is prepared and the upper presser 6
6C of the disengagement piece of Kapock fiber forming the oil-impregnated member 7
Against the elasticity of the above, the retaining claws 6B are pushed downward by lowering them, and the upper retainer 6 is moved to the rear side (rightward in the figure) and pulled out from the collar 4A. Next, the old oil-impregnated member unit 10 is pulled out from the case 4, a new unit 10 is mounted, and then the collar 4A and the groove 6A of the upper presser 6 are engaged with each other and moved from the rear side to the left. As a result, the new unit 10 is fixed to the case 4. The newly installed 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.

As described above, according to this embodiment, the oil-impregnated member unit 10 can be replaced very easily and in a short time, and the oil-impregnated member unit 1 of the guide rail lubricating device can be replaced.
Since the detachable oil-impregnated member unit 10 is used for the case 4 of the engagement device 2 that holds 0, it is possible to prevent excessive oil supply to the guide rail surface, and reduce the consumption of lubricating oil and the labor of maintenance personnel. Can be reduced. It is also possible to prevent contamination of the inside of the elevator car and the clothes of the elevator user.

[0012]

As described above, according to the present invention, the lower end of the case is inwardly projected to serve as a lower support, and the upper end is a plug-type upper retainer which is inserted into the collar from the rear side. For replacement and inspection, the oil retaining member can be taken out from the case by pulling out the upper presser to the rear side, and replacement and inspection work can be performed easily and in a short time.
