Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator guide rail lubrication system, and more particularly to an elevator guide rail lubrication system that uses a flexible oil-impregnating member to supply oil.

[Conventional technology]

For elevators configured to guide the movement of elevating objects such as elevator cars and counterweights by sliding on guide rails, an appropriate amount of lubricant should be supplied to the sliding parts to ensure smooth sliding. ing.
In order to supply lubricating oil to a smaller and simpler lubricating device, a system has been developed in which a flexible oil-impregnated member impregnated with lubricating oil is pressed against the sliding surface of the guide rail (Japanese Patent Laid-Open No. 61-150977).

[Problem that the invention seeks to solve]

According to the above-mentioned lubricating device, there is no need to provide a special oil tank, and the entire device has the advantage of being small and simple. , the initial shape cannot be maintained and the deformation occurs, and the deformation may instantly slip out of the small gap between the holding body and the guide rail when the elevating body is raised and lowered.

The present invention has been made in view of the above points, and its purpose is to provide a reliable elevator guide rail lubrication device that can hold a flexible oil-impregnated member in a fixed position within a holder for a long period of time. There is a particular thing.

[Means to solve the problem]

The above object is to attach the flexible oil-impregnated member to a reinforcing body having rigidity in the sliding direction, and to provide a holder that holds the flexible oil-impregnated member with a locking part that locks with the reinforcing body in the sliding direction. This is achieved by

[Effect]

With the above configuration, even if the flexible oil-impregnated member tries to deform, the flexible oil-impregnated member is maintained in a shape close to its initial state by the reinforcing material, and the reinforcing material is prevented from moving in the sliding direction between the reinforcing material and the holding material. Because there are
The flexible oil-impregnating member can be held in a fixed position within the holding body for a long period of time.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. An elevator car 1 is broadly divided into a suspension frame 1 and a car chamber 6. The hanging frame 1 has a lower beam 2, an upper beam 4, vertical 3A, 3B.
The car compartment 6 is supported on the lower beam 2 via a vibration isolating member 5. A guide shoe 7 is provided on the extension line of the vertical frames 3A, 3B of the hanging frame 1 configured in this way, and is engaged with the fixed guide rails 8A, 8B to slide, thereby raising and lowering the car 1. I'm trying to guide you. Then, this guide shoe 7 is placed near the upper guide shoe 7 on the guide rail 8.
Lubricating device 9 that supplies lubricating oil to the sliding surfaces of A and 8B
is provided. This lubricating oil 9 is
As shown in the figure, the U-shaped groove surface 1 is formed in a U-shape.
4 and a holding body 13 consisting of flanges 15A and 15B provided on the inside of the U-shape at both ends of the U-shaped groove 14, and mounting for attaching this holding body 13 onto the guide shoe 7 of the car 1. 16. Then, the refueling tool 10 is installed in the U-shaped groove 14 of the holding body 13, and the refueling tool 10 is made of a net-like holding member on the surface of a nonwoven mat made of fibers such as Kapok fiber or a polymeric material. It is composed of a flexible oil-impregnated member 11 that is covered with a flexible oil-impregnated member 11, and a reinforcing thin plate 12 made of, for example, an aluminum thin plate, a thin steel plate, or a synthetic resin plate. Specifically, the flexible oil-impregnated member 11 is pasted and integrated with one side of the reinforcing thin plate 12 made of a single plate using an adhesive, and this is attached to the sliding surface of the guide rails 8A and 8B with the flexible oil-impregnated member 11 inside. It is folded into a U-shape so as to cover it from three directions. Then, the bent refueling tool 10 is inserted into the U-shaped groove 14 of the holder 13.
installed inside. At this time, the reinforcing thin plate 12
It is important to make the size so that a large gap does not occur between it and the U-shaped groove 14, and the length should be approximately the same as the dimension between the flanges 15A and 15B provided at both ends of the U-shaped groove 14. have. The holding body 1 is
When installed in the U-shaped groove 14 of No. 3, both U-shaped leg ends 12E come into contact with the holder 13 with pressure, and at the same time, both longitudinal ends of the reinforcing thin plate 12 contact the flange 15A of the holder 13. , 15B, so it will not fall during the installation process. If it is difficult to bend the reinforcing thin plate 12 into the same U-shape as the U-shaped groove 14 of the holder 13, cut a groove in advance at the position where it should be bent or cut a perforation. It may be made easier to bend by inserting a Furthermore, the reinforcing thin plate 12 needs to have enough rigidity to hold the flexible oil-impregnated member 11 over the entire length of the holder 13 even if the flexible oil-impregnated member 11 is repeatedly slid against the guide rails 8A and 8B. It is.

Since the lubricating device according to the embodiment of the present invention is constructed as described above, the flexible oil-impregnating member 11 is connected to the guide rails 8A, 8
Even if it tries to deform due to repeated sliding with B,
Since the back surface is supported by the reinforcing thin plate 12, the initial state can be maintained for a long period of time, and the flexible oil-impregnated member is prevented from shifting due to deformation and the holder 13
There will be no way out. In addition, the refueling tool 10
represents the longitudinal end of the flexible oil-impregnated member 10 and the reinforcing thin plate 1
1 and the flange 15A of the holding body 13, 1
5B, there is no displacement of the flexible oil-impregnating member compared to a case where the flexible oil-impregnating member is locked only. This is because the reaction force of the bending of the reinforcing thin plate 12 causes the locking position with the flanges 15A and 15B to always span the entire width of the flanges, and as in the conventional case, the locking relationship gradually becomes shallower due to the deformation of the flexible oil-impregnated member. This is because it cannot be said that it will eventually be displaced.

On the other hand, by bending the reinforcing thin plate 12 into a U-shape, the buckling strength of the reinforcing thin plate itself can be improved, so that it is possible to make the reinforcing thin plate that much thinner.

Furthermore, by using the reinforcing thin plate 12,
The flexible oil-impregnating member 11 can be easily attached to and detached from the holder 13, which has the effect of shortening the working time.

By the way, in the above embodiment, a flexible oil-impregnating member is attached to a reinforcing thin plate and this reinforcing thin plate is held in a holder, but instead of bending and using the single reinforcing thin plate, a thick strip-shaped plate is used. The flexible oil-impregnating member may be attached across the three plates by using three plates, and it is also possible to use not only the plate but also a rod-shaped reinforcing body.

〔Effect of the invention〕

As explained above, since the flexible oil-impregnated member can be held in a fixed position within the holder for a long period of time, the oil supply to the guide rail sliding surface is stable, and as a result, a reliable elevator guide rail lubrication device can be obtained. I can do it.
