Abstract

PURPOSE:To collect the oil fed to a guide rail without scattering, by providing an oil drop collecting box to receive the oil dropped to the lower side of a guide shoe, movable up and down. CONSTITUTION:At the lower side of a guide shoe 4, an oil drop collecting box 12 having a roller 10 to slide on a guide rail 3 is provided movable up and down, and an installing arm 15 provided in the guide rail 3 through a fixing clip 14 holds the oil drop collecting box 12 through an operating member 19 which consists of a spring 16 and a pair of tube bodies 17 and 18. In such a constitution, the height of the fixing clip 14 is regulated, so as to make the position of the oil drop collecting box 12 superposed a little with the guide shoe 4, when a cage frame 1 reaches to the floor surface of the lowermost floor. When an elevator is operated up and down after that, the oil drops 7 dropped from the guide shoe 4 are absorbed in an oil absorbing substance in the oil drop collecting box 12, so as to prevent their scattering. When the oil overflows from the collecting box 12, it is collected on an oil pan 5 by moving down along the operating member 16.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil splattering device for refueling a guide rail, and more particularly to recovering the oil spilled on the guide rail without scattering it.

[0002]

2. Description of the Related Art As a conventional oil scattering prevention device in this type of guide rail oil supply, the structure shown in FIG. 6 is generally adopted. That is, in FIG. 6, 1 is a car frame, 2 is a guide shoe mounting bracket for connecting the guide shoe 4 sliding on the guide rail 3 to the car frame 1, and 5 is an oil provided on the pit floor surface 6. It is a saucer.

In the above-mentioned structure, the oil supplied to the guide rail 3 naturally falls along the guide rail 3 and collects in the oil receiving tray 5 below. On the other hand, the oil is transmitted along the contact surface of the guide shoe 4 and the guide shoe 4. 4 gathers in the lower portion 4a and drops as an oil drop 7. In the case described above, when the elevator runs, the oil pressure 7 collected in the lower portion 4a is scattered by the wind pressure, and the car, the hanging weight, the hoistway and the pit are contaminated, and it takes a lot of labor and time to clean them. I was supposed to.

Further, as another conventional example, although not shown, the elevator guide rail lubrication device disclosed in Japanese Utility Model Laid-Open No. 62-121261 can be mentioned. A lubricating oil holding device having an oil absorbing member is provided, and the oil accumulated in the lubricating oil holding device is supposed to be scattered below the pit.

The present invention has been made in order to solve the above problems, and in particular, provides an oil splash prevention device for oil feed to a guide rail that collects the oil fed to the guide rail without scattering. The purpose is to

SUMMARY OF THE INVENTION An oil splash prevention device for refueling a guide rail according to the present invention includes a car frame that moves up and down via a guide shoe that slides on an upright guide rail, and the guide shoe. The configuration is provided with an oil drop dust collecting box located below and for receiving oil falling from the guide shoe, and an operating member for vertically moving the oil drop dust collecting box.

[0007]

In the oil splattering preventive device for refueling the guide rail according to the present invention, the oil replenished on the guide rail is collected in the guide shoe, and the oil drops falling from the guide shoe when the elevator is moved up and down are the oil drop dust collecting box. It is housed in and prevented from scattering. Finally, the oil droplets are guided from the oil droplet collecting box to the oil receiving tray below and stored.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of an oil splash prevention device for refueling a guide rail according to the present invention will now be described in detail with reference to the drawings. It should be noted that the same or equivalent portions as those of the conventional example will be described using the same reference numerals. 1 to 5 show an oil splattering preventive device for refueling a guide rail according to the present invention. FIG. 1 is a block diagram, FIG. 2 is a block diagram showing the operation of essential parts of FIG. 1, and FIG. FIG. 4 is a perspective view showing the operation of the main part, FIG. 4 is a plan view showing the operation of the main part, and FIG. 5 is a plan view showing the operation of the main part.

In FIG. 1, 1 is a car frame, 2 is a guide shoe mounting metal fitting for connecting a guide shoe 4 sliding on a guide rail 3 to this car frame 1, and 5 is provided on a pit floor surface 6. It is an oil pan. Below the guide shoe 4, an oil drop collection box 12 provided on a roller fixing arm 11 having a roller 10 sliding on the guide rail 3 is provided so as to be vertically movable. The dust box 12 is filled with an oil absorbing member 13 (shown in FIG. 3) such as felt.

A mounting arm 15 provided on the guide rail 3 via a fixing clip 14 is provided with an actuating member 19 consisting of a spring 16 and a pair of cylinders 17, 18. The oil drop dust collecting box 12 and the mounting arm 15 are connected to each other, and the cylinders 17 and 18 are fitted to each other via a spring 16 so as to be vertically expandable and contractable. Further, by freely setting the mounting position of the fixing clip 14 on the guide rail 3, the mounting height position of the mounting arm 15 can be freely set.

In the above structure, when the car frame 1 of the elevator is moved up and down, first, the height of the fixing clip 14 is adjusted so that the car frame 1 becomes the bottom floor stop floor as shown in FIG. When it reaches the oil drop collection box 12, the guide shoes 4 and 1
The fixing clip 14 is set and fixed at a position where it overlaps by about 0 mm.

After that, when the elevator is moved up and down, the oil droplets 7 scattered from the guide shoes 4 are collected in the oil droplet dust collecting box 1.
It can be absorbed by the oil absorber 13 in 2 and prevented from scattering. Further, when the oil in the oil absorber 13 becomes saturated, for example, the oil is transmitted through the operating member 16 and falls on the oil receiving tray 5 to be collected. Therefore, it is possible to effectively prevent the oil droplets from scattering during the elevator operation. The above-mentioned actuating member 19 is not limited to a spring, but may be another elastic member.

[0013]

Since the oil splash prevention device for refueling the guide rail according to the present invention is constructed as described above, the oil drops falling from the guide shoes are contained in the oil drop dust collecting box, and are used during elevator operation. It is possible to prevent oil droplets from scattering.
