Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator guide rail lubrication device for supplying oil to a sliding surface of a guide rail.

[0002]

[Prior art]

 Generally, an elevator connects a guide shoe to a moving body such as a car or a counterweight, and engages the guide shoe with a guide rail fixed to a hoistway wall to guide the moving body along the guide rail. Is configured. Further, a guide rail lubrication device for supplying lubricating oil is provided on the engagement surface between the guide rail and the guide shoe, and this guide rail lubrication device is disclosed, for example, in Japanese Utility Model Laid-Open No. 62-132084. The oil-impregnated member was housed in a case attached to the moving body, and this oil-impregnated member was fixed to the case by a fixing screw.

[0003]

[Problems to be solved by the device]

 However, in the conventional elevator guide rail lubrication system, the oil-impregnated member housed in the case is fixed to the case by the fixing screw as described above, so the fixing screw must be removed each time the oil-impregnated member is replaced or inspected. However, this work was complicated and required a lot of time.

An object of the present invention is to provide an elevator guide rail lubrication device that can easily replace an oil-containing member in a short time.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a moving body having a guide shoe engaged with a guide rail fixed to a hoistway wall, in which a sliding surface of the guide rail is provided with an oil-impregnated member for supplying oil. In the elevator guide rail lubrication device to be installed, the case has a receiving portion for the oil-impregnated member formed below, and an outward flange formed at an upper end, and is rotatably attached to the flange. A stopper for holding the oil-impregnated member inside the case is provided, and the minimum facing distance between the stopper and the sliding surface of the guide rail is set to be larger than the distance between the guide rail and the guide shoe. And

[0006]

[Action]

 The guide rail lubrication device for an elevator according to the present invention holds the oil-impregnated member in the case as described above. Therefore, when inspecting and replacing the oil-impregnated member, the oil-impregnated member should be removed upward from the case by rotating the stopper. Further, even after the oil-impregnated member is housed, the stopper can be prevented and held by simply rotating the stopper, and the oil-impregnated member can be replaced easily and in a short time.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 3 is a perspective view of a case, which is a main part of an elevator guide rail lubricating device according to an embodiment of the present invention. The case 6 has a U-shaped cross-section excluding the side facing the guide rail, a lower end thereof is provided with a receiving portion 8 formed of an inward flange, and an upper end thereof is formed outward. It has a brim 6A. The collar 6A is provided with at least one pair of rotatable stoppers 9 by rivets 6B. The stoppers 9 can be stored on the collar 6A as shown in the drawing, and the tip of the collar 9 can be rotated by the rotation. It can be made to project more than the inner edge of 6A.

1 and 2 are a plan view and a side view of a guide rail lubricating device for an elevator according to an embodiment of the present invention using the case 6 described above. A guide shoe fixed to a moving body such as a car or a counterweight is engaged with the guide rail 1 fixed to the hoistway wall, and the moving body travels along the guide rail 1 by this engagement. The lubricating device that lubricates the sliding surface of the guide rail 1 fixes the above-mentioned case 6 to the moving body side by a mounting portion 5 bent at a substantially right angle and a reinforcing member 4 that reinforces the mounting portion 5. The oil-impregnated member 2 having the plate frame 7 is housed in the interior 6. The lower end of the case 6 has an inwardly short brim 8 so that the guide rail 1 can be arranged. The oil-impregnated member 2 inserted from above the case 6 is placed on the brim 8 and as shown in FIG. The oil-impregnated member 2 is in contact with the sliding surface of 1. The upper part of the oil-impregnated member 2 is pressed by rotating the stopper 9 rotatably attached to the collar 6A so that the free end of the stopper 9 protrudes beyond the inner edge of the collar 6A. In this way, the oil impregnating member 2 is held in the case 6. At this time, the distance between the free end of the stopper 9 and the guide rail 1 becomes the minimum, and this minimum facing distance is made smaller than the distance between the guide rail 1 and the guide shoe, so that the distal end of the stopper 9 becomes smaller. Does not contact the guide rail 1.

When a maintenance worker looks at the lubricating state of the sliding surface of the guide rail 1 and determines that the oil-impregnated member 2 needs to be replaced, the stopper 9 is rotated to be stored in the plane of the collar 6A. Then, the oil-impregnated member 2 is pulled out upward from the case 6. Next, a new oil-impregnated member 2 is inserted from above the case 6 and mounted in the case 6, and the stopper 9 is rotated again to the state shown in FIG. 1 to move the oil-impregnated member 2 from above the case 6 while the elevator is traveling. Prevent getting out. When the oil-impregnated member 2 needs to be replaced in this way, it can be taken out simply by rotating the stopper 9, and the work can be performed easily and in a short time, and the structure is simple and inexpensive to manufacture. can do.

[0010]

[Effect of device]

 As described above, the guide rail lubrication device for an elevator according to the present invention forms the receiving portion below the case to support the oil-impregnated member, and the upper end of the case forms an outward flange, which is pivoted to this flange. Since the oil-impregnated member is held by the stopper that can be attached, the oil-impregnated member can be easily and easily removed from the case by simply rotating the stopper when exchanging.
