Abstract

PROBLEM TO BE SOLVED: To replace a flexible oil-contained member only by loosening a bolt by forming a bolt hole of a holder fixed to an elevating body in such a way as to press the flexible oil-contained member to the sliding face of a guide rail, as an oblong hole allowing the movement of the support in the direction of being separated from the guide rail. SOLUTION: A base part 6 of a holder 5 for holding a kapok member 4 is provided with a hole for inserting a bolt for fixing the holder 5 to a car, that is, an oblong hole 10 allowing the movement of the holder 5 in the direction of being separated from a guide rail. At the time of replacing the kapok member 4 with new one, the bolt is loosened to move the holder 5 in the direction of being separated from the guide rail. A clearance is formed between the guide rail and the holder 5, and the kapok member 4 enclosed in the holder 5 can be pulled out from this clearance. The raw kapok member 4 can be enclosed in the holder 5 from this clearance. The holder 5 with the kapok member 4 enclosed therein is sufficiently pushed out toward the guide rail, and then the bolt is fastened to complete replacement work.

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 for supplying lubricating oil to a sliding surface of a guide rail.

[0002]

2. Description of the Related Art FIG. 4 is an exploded perspective view showing a conventional guide rail lubrication device for an elevator, and FIG. 5 is a side view showing a state where the guide rail lubrication device shown in FIG. 4 is installed. As this kind of prior art, there is one disclosed in Japanese Patent Application Laid-Open No. 63-315482.

In FIG. 5, 1 is an elevator car,
2 is a guide rail for slidingly guiding the car 1, and 3 is a conventional guide rail lubrication device. As shown in FIG. 4, the guide rail lubricating device 3 includes a soft oil-impregnated member that supplies lubricating oil to the sliding surface of the guide rail 2, for example, a kapok material 4 formed into a fibrous body, and the kapok material 4. And a holding body 5 for holding the sliding surface of the guide rail 2 so as to press it. The base 6 of the holder 5 includes
A hole into which a bolt 7 for fixing the holder 5 is inserted, that is, a round hole 8 is provided in an upper part of the car 1.

[0004] The guide rail lubricating apparatus 3 described above is similar to that of FIG.
In the state where the kapok material 4 shown in FIG.
The gap portion 9 of the kapok material 4 is disposed on the guide rail 2 so as to sandwich the sliding surface of the guide rail 2, and as shown in FIG. Fixed to For example, the lubricating oil is impregnated into the kapok material 4 in such a state.

When the car 1 is raised and lowered, the lubricating oil that has soaked into the kapok material 4 is applied to the sliding surface of the guide rail 2. Thereby, the car 1 can be smoothly operated along the guide rail 2.

[0006]

In the conventional guide rail lubricating apparatus 3 shown in FIGS. 4 and 5, when the kapok material 4 needs to be replaced due to abrasion, breakage, or the like, the bolt 7 must be removed once every time. Therefore, there is a problem that the replacement work of the kapok material 4 becomes complicated.

Further, since the holding member 5 is fixed at a position uniquely determined by the round hole 8, there is a slight displacement between the guide rail 2 and the kapok member 4 mounted on the holding member 5. Cannot be dealt with even if it occurs.

[0008] Even with such a slight displacement, if the car 1 repeatedly moves up and down, the wear of the kapok material 4 is promoted and the life of the kapok material 4 is reduced.

The present invention has been made in view of the above circumstances in the prior art, and a first object of the present invention is to replace a flexible oil-impregnated member without completely removing a bolt, that is, simply by loosening the bolt. It is an object of the present invention to provide a guide rail lubrication device for an elevator.

It is a second object of the present invention to provide an elevator guide rail lubrication device capable of suppressing wear of a soft oil-impregnated member during use.

[0011]

In order to achieve the first object, the invention according to the first aspect of the present invention is directed to a lifting / lowering body slidably guided on a guide rail via a bolt. A flexible oil-impregnated member that is fixed and supplies lubricating oil to the sliding surface of the guide rail; and a holder that holds the flexible oil-impregnated member against the sliding surface of the guide rail so as to be pressed. In an elevator guide rail lubrication device having a hole into which the bolt is inserted, the hole is formed of an elongated hole that allows the holding body to move in a direction away from the guide rail.

According to the first aspect of the present invention, when the flexible oil-impregnated member is replaced, if the bolt fixing the holding body is loosened, the relationship between the bolt and the elongated hole is obtained.
The holding body can be moved away from the guide rail, whereby a gap can be formed between the guide rail and the holding body, and the flexible oil-impregnated member can be removed from the gap. Also, a new flexible oil-impregnated member can be inserted from the above-mentioned gap and attached to the holder, and in this state, the holder is moved in the guide rail direction, and the bolt is tightened, so that the guide rail can be lubricated. be able to.

In order to achieve the above-mentioned second object, the invention according to claim 2 of the present invention provides another aspect of the present invention, wherein the holder is connected to the elongated hole to allow the holder to move in the lateral direction. It has a configuration in which a horizontal hole composed of a long hole is provided.

According to the second aspect of the present invention, the holding body can be moved back and forth and right and left with respect to the bolt for fixing the holding body through the elongated hole and the lateral hole. The positional relationship between the rail and the flexible oil-impregnated member can be set optimally. Therefore, wear of the soft oil-impregnated member during use can be suppressed.

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an elevator guide rail lubricating apparatus according to the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing one embodiment of the present invention, FIG. 2 is a side view showing an installation state of the embodiment shown in FIG. 1, and FIG. 3 is prepared for the embodiment shown in FIG. FIG. 7 is a side view showing a state when a flexible oil-impregnated member is replaced.
