Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a guide rail lubricating device for lubricating an engagement device that guides a moving body along a guide rail.

[Conventional technology]

Generally, a moving body such as an elevator is configured by providing an engaging device on the moving body and movably fitting the engaging device to a guide rail to guide the moving body along the guide rail. The guide rail lubricating device for supplying lubricating oil to the fitting surfaces of the guide rail and the engagement device has been constructed of a case and a cover as described in Japanese Patent Application Laid-open No. 147347/1983. The lubricating oil in the case is supplied to the guide rail by capillary action via an oil-absorbing, oil-absorbing member made of fibrous material such as felt.

This type of lubricating system consumes a large amount of wasted oil because lubricating oil is continuously supplied from the lubricating system from the previous day's stop of the elevator to the next day's start, or even during a fairly long interval. To compensate for this, lubricating oil had to be continuously supplied to the replenishment oil storage case.

[Problem that the invention attempts to solve]

In the conventional guide rail lubricating device described above, oil is supplied without considering the supply and demand balance, so that excessive oil adheres to the guide rail surface. As a result, the engaged device of the activated elevator car scrapes up this excess oil and scatters the oil onto the hoistway portion other than the guide rail, with some of the oil splashing onto the car. Due to its seepage and diffusion properties, the oil spilled onto the car could seep into the car interior through gaps in the walls that make up the car, staining the inside of the car and the clothes of elevator users.

Furthermore, since the amount of lubricating oil consumed was large, maintenance personnel were required to put in a lot of effort to replenish the lubricating oil.

The present invention is intended to eliminate the above-mentioned drawbacks, and its purpose is to provide a guide rail lubricating device that maintains an appropriate balance between supply and demand of lubricating oil and saves the labor of maintenance personnel.

[Means for solving problems]

In order to achieve the above object, the present invention includes an oil-impregnated member unit supported from behind by a plate frame, which is removably attached to the engagement device, and which is attached to the sliding surface of the guide rail. The guide rail lubrication device is configured to supply oil.

[Effect]

Since the guide rail lubricating device according to the present invention is constructed as described above, the sliding surface of the guide rail is kept in a proper lubricated state by the oil-impregnated member unit impregnated with a predetermined amount of lubricating oil in advance, and the oil-impregnated member is kept in an appropriate lubricated state. When the amount becomes low, the unit can be easily removed and replaced, so there is no need to continuously replenish lubricating oil as in the past, and a great deal of labor on the part of maintenance personnel can be saved.

〔Example〕

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

1 and 2 are a plan view and a side view of a guide rail lubricating device. and oil-impregnated member unit 1
It is composed of 0. The engagement device 2 consists of a mounting portion 3 bent at right angles by a reinforcing member 11, and an engagement portion 4 provided on one side outside of the mounting portion 3 and having a U-shaped cross section. And this engaging part 4
An oil-impregnated member unit 10 having a U-shaped cross section and supported from behind by a plate frame 9 is fitted into the recess, and is fixed by a retainer 5 and a set screw 6 provided at both ends of the engaging portion 4. has been done.

FIG. 3 is an enlarged perspective view of the oil-impregnating member unit 10, in which the oil-impregnating member 7 and the plate frame 9 are bonded together and constitute the unit.

The material of the plate frame 9 of the oil-impregnated member unit 10 is as follows:
Any solid material may be used as long as it has the effect of imparting a U-shape to the oil-impregnated member 7 and has relatively high deformation resistance. Additionally, kapoku fiber or the like may be used as the material for the oil-impregnated member 7.

Next, the operation will be explained. When a maintenance worker enters the elevator hoistway and determines that it is necessary to replenish the lubricating oil by checking the lubrication state of the sliding surface of the guide rail 1, he prepares a new oil-containing member unit 10 and tightens the stopper of the engaging part 4. The screw 6 is loosened, the retainer 5 is removed, the old oil-impregnating member unit 10 is pulled out from the engaging part 4, the new unit 10 is fitted, and the retainer 5 and set screw 6 are used to fix the new unit 10. The newly installed oil-impregnating member unit 10 is in contact with the sliding surface of the guide rail 1, and as the movable body 8 moves, the sliding surface is supplied with oil.

As described above, according to this embodiment, since the removable and replaceable oil-impregnated member unit 10 is used in the engagement portion 4 of the engagement device 2 that holds the oil-impregnated member unit 10 of the guide rail lubricating device, the guide rail Excessive lubrication of surfaces can be prevented, reducing lubricant consumption and maintenance personnel's labor. It also prevents staining of the interior of the elevator car and the clothes of elevator users.

[Effect of idea]

As explained above, the present invention is a guide rail lubricating device equipped with an oil-containing member unit that can be attached to and replaced with an engaging device attached to a moving body. Compared to the case where the lubricant is supplied with lubricant and maintenance personnel continuously replenish the lubricant, the lubricant supply and demand balance can be maintained appropriately and maintainability can be improved.
