Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator guide rail lubrication device for guiding an elevating body through a guide shoe.

[0002]

2. Description of the Related Art A conventional device of this type is disclosed in Japanese Patent Laid-Open No.
As described in Japanese Patent No. 375007, a vibration-proof rubber is provided between the outer surface of the shoe support member and a frame supporting the shoe support member, and is constituted by a dogleg-shaped leaf spring that restricts the displacement of the vibration-proof rubber. As described in Japanese Utility Model Laid-Open No. 59-116363, a slider provided on a support frame supporting a shoe via an elastic member, and a body freely attached to a side end of a sliding surface of the slider. There is known a slider guide portion that is elastically held and has a contact surface that comes into pressure contact with the guide rail and is configured to be separable from the guide rail.

[0003]

The conventional guide shoes described above have the following problems. Since the V-shaped leaf spring configured as described above has a natural vibration in the V-shaped leaf spring, the vibration may be amplified when it resonates with the vibration generated during traveling. Also, with a guide shoe with a structure with a slider, in order to prevent wear and vibration of the slider,
More lubricating oil must be supplied than would normally be supplied. Therefore, the pollution of the surroundings of the car, the inside of the tower, and the pits due to the excessively supplied lubricating oil increases.

Further, dust floating in the hoistway adheres to the surface of the engaging portion of the guide rail, and this dust is combined with the lubricating oil film formed on the surface of the guide rail to form a clay-like formation. Since this formation increases the frictional resistance between the guide rail and the guide shoe, the vibration noise increases as a result.

An object of the present invention is to provide an elevator guide rail lubrication device capable of preventing vibration noise and maintaining an appropriate lubricating oil film while cleaning the guide rail portion.

[0006]

The above object is to provide a guide shoe support member fixed to an elevating body, a guide shoe attached to the guide shoe support member, and at least one guide shoe support member above and below the guide shoe support member. A holder member provided in the holder member, and an oil supply member provided in the holder member. The oil supply member is provided with a U-shaped opening that abuts an engaging portion of the guide rail, and an opening inside the holder member. This is achieved by providing a plurality of rod members that hold the oil supply member near the portion.

Since the present invention is configured as described above, since the oil supply member housed in the holder member forms an oil film on the guide rail portion and contacts the oil supply member guide rail with appropriate pressure, the guide Since dust that adheres to the rail surface and causes vibration is removed, the guide rail surface is always kept in a good condition with less vibration.

Further, since the refueling member is constructed with a low density so as not to be in a hypertonic state and is used in a region having no natural vibration, the vibration noise generated from the contact surface between the guide shoe and the rail has a wide range of frequencies. Vibration noise can be absorbed across the belt.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below.
This will be described with reference to FIGS.

In the figure, 1 is a refueling member, 2 is a box-shaped holder member for accommodating the refueling member 1, 2B is a plurality of bar members for holding the position of the refueling member 1, and 2C is a holder member 2.
A detachably attached lid, 3 is a guide shoe support member attached to an elevating body 7 composed of a car or a counterweight, 4 is a guide shoe held by the guide shoe support member 3, and 5 is a guide shoe support. Mounting members for mounting the holder members 2 on the upper and lower parts of the member 3 respectively, and 6 are guide rails supported by a bracket (not shown) on a wall for raising and lowering the elevator. The holder member 2 is made of synthetic resin and has an opening 2A into which the engaging portion 6A of the guide rail 6 is inserted. In the vicinity of the opening 2A inside the holder member 2, three metal rod members 2B are provided upright. The oil supply member 1 is guided by the rod member 2B and is brought into contact with the engaging portion 6A of the guide rail 6 via the reinforcing fiber 1A of the oil supply member 1. 1A is sewn to the guide rail engaging surface 6A of the oil supply member 1 on the U-shaped surface that abuts on the abutting engaging portion 6A with reinforcing fiber such as aramid fiber. The refueling member 1 is
A plurality of plate-shaped Kapok fibers are laminated.

When the lifting / lowering body 7 is moved vertically in this state, the rod member 2B provided in the vicinity of the opening 2A inside the holder member 2 causes the refueling member 1 to properly engage with the engaging portion 6A of the guide rail 6. Since they are in contact with each other with a great pressure, the frictional resistance between the guide shoe 4 and the guide rail 6 or the vibration noise generated from the joint step (not shown) of the guide rail 4 is absorbed by the elasticity of the oil supply member 1.

When the surface of the engaging portion 6A of the guide rail 6 is dried and the amount of lubricating oil becomes insufficient, the lubricating oil retained in the oil supply member 1 is supplied to the insufficient portion. Further, since the lubricating oil that has been over-lubricated in the engaging portion 6A of the guide rail 6 is absorbed by the oil supply member 1, the guide rail 6
The surface of the engaging portion 6A is a thin film of lubricating oil. This film of lubricating oil reduces the frictional resistance between the engaging portion 6A of the guide rail 6 and the guide shoe 4 which guides the lifting body 7, and the lifting body 7 runs smoothly.

Further, the reinforcing fiber 1A for protecting the oil supply member 1 attached above and below the guide shoe 4 has a cleaning effect of wiping the surface of the engaging portion 6A of the guide rail 6 as the lifting body 7 moves up and down. Therefore, the dust floating in the hoistway is combined with the film of the lubricating oil, and the engaging portion 6A of the guide rail 6 and the lifting body 7 are not formed in the engaging portion 6A of the guide rail 6 in the form of clay. Since it is possible to suppress an increase in frictional resistance with the guide shoe 4 for guiding, it is possible to prevent vibration noise from rising.

[0014]

As described above, according to the present invention, it is possible to prevent vibration noise and maintain an appropriate lubricating oil film while cleaning the guide rail portion.
