Abstract

PURPOSE:To prevent oil from splashing especially to surely recover oil in an oil drop prevention device for elevator guide shoe. CONSTITUTION:An oil drop prevention device for elevator guide shoe is provided with an oil absorbing member 10 located at the underside of a guide shoe 1 and a restriction stand 15 which is fixed to a rail 3 and movable vertically by an elastic body 17. When a car 2 is lowered, the oil absorbing member 10 is compressed to store oil in an oil pan 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil drop preventing device for a guide shoe of an elevator, and more particularly to preventing oil from scattering and reliably collecting oil.

[0002]

2. Description of the Related Art FIG. 6 shows a conventional oil drop prevention device for a guide shoe of an elevator, where 1 is a guide shoe which is attached to a lower portion of a car 2 and slides on a guide rail 3,
Reference numeral 4 is an oil pan provided on the pit floor 6 for receiving the dripping oil 5 of the oil supplied in the guide shoe 1.

Further, as another conventional example, a full-scale shokai 62-
The configuration disclosed in Japanese Patent No. 121261 can be mentioned, which is a configuration in which an oil absorbing member is internally provided in the guide shoe itself.

[0004]

Since the conventional oil drop preventing device for the guide shoe of the elevator is constructed as described above, there have been the following problems. That is, in the case of the configuration of FIG. 6, since no measures against oil drop from the guide shoe and splashes were taken, the lubricating oil supplied to the guide rail during elevator travel is accumulated at the bottom of the guide shoe, increasing the amount of oil. The current situation is that the oil does not enter the oil pan as dripping oil and is scattered on the pit floor. Further, in the case of the conventional configuration disclosed in Japanese Utility Model Laid-Open No. 62-121261, the oil is absorbed by the oil absorbing member of the guide shoe. However, when the oil absorbing capacity of the oil absorbing member is exceeded, the oil is dripping oil. It had fallen to the pit floor.

The present invention has been made to solve the above problems, and particularly provides an oil drop prevention device for an elevator guide shoe that prevents oil from scattering and surely recovers oil. The purpose is to do.

[0006]

Claims according to the present invention
The oil drop prevention device for the guide shoe of the elevator is
A guide shoe provided at the bottom of the car and sliding on the rail, and an oil absorbing member provided at the bottom of the guide shoe,
It is equipped with a diaphragm base fixed to the rail and configured to be movable up and down by an elastic body, and an oil pan located below the diaphragm base, and when the car is lowered, the oil absorbing member is pressed by the diaphragm base. The oil in the oil absorbing member is dropped onto the oil receiving tray.

[0007]

In the oil drop preventing device for an elevator guide shoe according to the first aspect of the present invention, the oil supplied to the guide shoe is sucked by the oil absorbing member provided under the guide shoe, and the car is kept in this state. Is dropped,
The oil absorbing member and the throttle base are in contact with each other, and the oil absorbing member is pressed to squeeze the oil. Since this squeezed oil falls and is collected in the lower oil pan, it is possible to prevent the oil from scattering from the guide shoe and the oil absorbing member. Since this diaphragm base is always urged upward by the elastic body,
When it is joined to the oil absorbing member, it lowers slightly downward, but when the car rises, it automatically returns to its original upper position by the action of this elastic body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of an oil drop preventing device for an elevator guide shoe according to the present invention will be described in detail below 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. Example 1. 1 to 5
Up to this point, the oil drop prevention device for an elevator guide shoe according to the present invention has been constructed. In FIG. 1, 1 is a basket 2
A guide shoe 10 mounted on the lower part of the guide slides on the guide rail 3, and a guide screw 10 is mounted on the lower part of the guide shoe 1 with a mounting screw
An oil absorbing member provided on the mounting plate 1A provided via Aa (shown in FIG. 2), and 11 is a throttle body fixed to the lower portion of the rail 3 for squeezing the oil absorbing member 10.

The throttle body 11 is constructed as shown in FIG. 2 to FIG. 4, and a pair of through bars 13 form a gap a in an elastic body pedestal 12 fixedly provided on the lower portion of the rail 3. The threaded portion 13a formed at the lower portion of the threaded rod 13 is provided with a nut 14 screwed therethrough. In addition, this elastic body support 12
As shown in FIG. 4, the bolt 1 is attached to the elastic base 12.
The rail 3 is clamped by an L-shaped rail fixing clip 12C provided via 2A and a nut 12B so that the rail 3 can be mounted at any mounting position.

A plate-shaped diaphragm base 15 is integrally provided on the upper part of each of the through rods 13, and elastic plate trays 16 and 16A are provided between the elastic body base 12 and the diaphragm base 15, respectively. An elastic body 17 made of a spring is interposed through the elastic body 17 and each elastic body 17 is provided so as to wind the through rod 13. The elastic bodies 17 are not limited to springs, and other elastic members can be used. The nuts 14 are provided in order to keep the amount of expansion of the elastic body 17 within a predetermined range. By freely adjusting the position of the nut 14, the amount of expansion of the elastic body 17 can be set freely. can do.

In the above configuration, the elevator car 2
When the oil is dropped along the rail 3, the oil absorbing member 10 contacts the diaphragm base 15 and is compressed as shown in FIG. 5, so that the oil accumulated in the oil absorbing member 10 via the guide shoe 1 is squeezed and dropped. The oil 5 drops downward and is collected in the oil pan 4 on the pit floor 6.

Next, when the elevator is raised and the car 2 is raised, the contact between the oil absorbing member 10 and the throttle base 15 is released, the compression of the oil absorbing member 10 is lost, and the original shape is restored and the oil absorbing oil is absorbed again. It can be performed. In addition, the diaphragm 1
The mounting and fixing position of 1 is when the elevator is on the lowest floor regular landing,
It is attached to a position where oil can be squeezed by coming into contact with the oil absorbing member 10 or the diaphragm base 15.

[0013]

Since the oil drop preventing device for the guide shoe of the elevator according to the present invention is constructed as described above, the following effects can be obtained. That is, since the oil absorbing member that descends together with the car is compressed by the throttle base that moves up and down by the elastic body, the oil can be squeezed out from the oil absorbing member each time the elevator descends, and the oil from the guide shoe can be completely removed. It is possible to guide toward the oil pan, and it is possible to completely prevent the guide from scattering to the pit floor surface or the like.
