Abstract

PROBLEM TO BE SOLVED: To replace a lubricating member efficiently by attaching one piece of a plate spring part to a bottom face of a hold body and the other piece to a top face of a bracket and fixing and holding the hold body on the bracket by predetermined spring force. SOLUTION: A plate spring part 9 is provided nearer to a guide rail side than a turning support part 10, one piece thereof is attached to a bottom face of a held body 7, and the other piece thereof is attached to a top face of a bracket 5. Spring force of this plate spring part 9 is set in such a manner that it suppresses the tilt of the held body 7 due to the ascent and descent of a car and a worker can turn the held body 7 without any trouble. Consequently, since the held body 7 and the bracket 5 are fixed and held, the held body 7 is not tilted even if impact force generated due to the ascent and descent of the car is applied to the held body 7, lubricating member comes into contact with a guide rail at all times, and lubricating oil is supplied to the guide rail sufficiently.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator guide rail oil supply device for supplying lubricating oil to guide rails.

[0002]

2. Description of the Related Art A conventional guide rail refueling device for an elevator will be described with reference to FIG. FIG. 3 is a perspective view showing a conventional guide rail refueling device for an elevator.

In FIG. 1, a guide rail 1 is provided upright in a hoistway to guide the elevator (not shown) of a car.

The car is guided by the guide rail 1 by engaging a guide shoe 2 attached to the car with the guide rail 1, and moves up and down in the hoistway.

A lubricating device 3 for supplying lubricating oil to the guide rail 1 is provided above the guide shoe 2, and the lubrication allows the car to move up and down smoothly.

The lubricating device 3 includes a bracket 5 fastened to the guide shoe 2 by a fastener 4, a holder 7 fastened to the bracket 5 by a fastener 6, and an inner side of the holder 7. Guide rail 1 to be stored and lubricating oil
And an oil supply member 8 for supplying the oil to the fuel tank.

Since the lubrication member 8 deteriorates as the car moves up and down, it needs to be replaced. At the time of replacement, the lubrication member 8 is inserted between the nut 6a of the fastener 6 and the bracket 5. By using the elastic force of the coil spring 6b, the holding member 7 is tilted to the side opposite to the guide rail 1, and the oil supply member 8 is replaced.

An example of this type of refueling device is disclosed in Japanese Utility Model Laid-Open No.
JP-A-37258 discloses the disclosure.

[0009]

However, in the prior art, the bracket 5 and the holder 7 are sandwiched by applying a spring pressure only to the rear end located on the rear side toward the guide rail 1. Therefore, when an impact force is applied due to friction with the guide rail 1 as the car moves up and down, the holding member 7
However, there was a problem in that the lubricating oil was tilted toward the back side and could not supply a sufficient amount of lubricating oil.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to enable efficient replacement of a lubrication member and to provide lubrication oil for an elevator guide rail lubrication. In providing the device.

[0011]

According to the present invention, a guide shoe engaging with a guide rail is provided.
In an elevator guide rail lubricating apparatus having an bracket fixed to the guide shoe and a holder attached to the bracket and holding an oil supply member for supplying lubricating oil to the guide rail inside the bracket, A rotation support portion rotatably supporting the rear end portion located on the back side toward the guide rail on the bracket, and a rotation support portion provided on the guide rail side from the rotation support portion, and one piece thereof is On the bottom surface of the holder, another piece is attached to the upper surface of the bracket, and a leaf spring portion for fixing and holding the holder to the bracket with a predetermined spring force is provided.

According to the present invention, as described above, the bracket and the holder are fixedly supported by the bracket such that the rear end of the holder is rotatably supported by the bracket, and the guide rail is provided by the rotation support. Side, and is configured to be performed by a plate spring portion that holds the holder to the bracket with a predetermined spring force, so that the plate spring portion suppresses tilting of the holder,
Sufficient lubricating oil can be supplied by the lubricating member.

The leaf spring portion suppresses the tilting of the holding member due to the raising and lowering of the car, and is set at a spring pressure that does not hinder the tilting of the worker. The refueling member can be efficiently exchanged.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a side view of a fueling device showing one embodiment of the present invention, and FIG. 2 is a side view showing a rotating state of the fueling device showing one embodiment of the present invention.

In the figure, a hinge 10 corresponds to a rotation support portion of the present invention for rotatably supporting a rear end portion of the holding member 7 located on the rear side toward the guide rail 1 on the bracket 5. .

The leaf spring 9 is provided on the guide rail 1 side with respect to the rotation supporting portion. One of the leaf springs 9 is attached to the bottom surface of the holder 7 and the other is attached to the upper surface of the bracket 5.

The spring force of the leaf spring portion 9 is set so as to suppress the tilting of the holder 7 due to the raising and lowering of the car and to prevent the worker from rotating the holder 7. I have.

As described above, according to the present embodiment, the holding member 7 and the bracket 5 are fixedly held in a wide range by the hinge 10 exemplifying the rotation supporting portion and the leaf spring portion 9. Even if an impact force due to the raising and lowering of the car is applied to the holder 7, the holder 7 does not tilt. Therefore, the lubricating member 8 always comes into contact with the guide rail 1, and the lubricating oil can be sufficiently supplied to the guide rail 1.

Further, since the leaf spring portion 9 is limited to such a degree that the worker does not hinder the rotation of the holding member 7, when the oil supply member 8 is replaced, as shown in FIG. By rotating the fuel supply 7, the oil supply member 8 can be easily and efficiently replaced.

[0021]

The present invention has the above-described structure,
It is possible to provide an elevator guide rail oil supply device that can efficiently replace an oil supply member and does not hinder the supply of lubricating oil.
