BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for improving the workability of an elevator main wire rope refueling jig, particularly in the work of refueling a main wire rope for suspending an elevator car with a spray type refueling device. Elevator main wire rope lubrication jig.

[0002]

2. Description of the Related Art A main wire rope for suspending an elevator car is driven to be wound around with load applied to both ends thereof as described later. Therefore, in order to operate the elevator smoothly and maintain the durability of the main wire rope, it is necessary to refuel the main wire rope with regular maintenance work. Conventionally, this refueling work is performed by a method of injecting oil using a spray type refueling device and spraying the oil onto the main wire rope. The lubrication work of this main wire rope will be described in detail below. 14 is a schematic diagram showing an outline of an elevator and a conventional main wire rope refueling work, and FIG. 15 is an enlarged view showing a portion of a worker in the refueling work of FIG.

First, the construction and operation of the elevator will be outlined. As shown in FIG. 14, an elevator car 1 on which an occupant rides or loads is located in a hoistway 2. The elevator car 1 is suspended by a main wire rope 3 having one end attached to the ceiling of the car. The main wire rope 3 is hung on an elevator drive device 4 provided at the top of the hoistway 2. At the other end of the main wire rope 3, a counterweight 5 is hung so as to maintain balance with the elevator car 1. When the elevator drive device 4 is driven, the main wire rope 3 is wound and driven, and the elevator car 1 suspended by the main wire rope 3 moves up and down.

As described above, the main wire rope 3 is hung and driven by the elevator drive device 4 in a state where the elevator car 1 and the counterweight 5 are hung and the load is received. In order to maintain the durability of the wire rope 3, it is necessary to refuel the main wire rope 3 with regular maintenance work. The refueling work using the conventional refueling spray will be described below.

As shown in FIG. 14, the worker 6 stands on the elevator car 1 to work. The worker 6 extends his hand from this position, brings the refueling spray 7 held in his hand close to the main wire rope 3 as shown in FIG.
The injection button 8 is pressed down to inject oil, and the main wire rope 3 is sprayed with oil to supply oil. By this work, the part of the main wire rope 3 within the reach of the worker 6 is refueled. Next, the worker 6 moves the elevator car 1 and stops it at a position where the unfilled portion above or below the filled portion can be filled, and the same filling operation as described above is performed. By repeating these operations, refueling is performed over the entire length of the main wire rope 3.

[0006]

The conventional lubrication work of the main wire rope as described above has the following problems.

That is, there is a problem in that the oil injected from the oil supply spray is scattered around the main wire rope and is scattered around and adheres to various parts of the elevator, causing dirt and malfunction. For example, in the case of a view elevator, if the sprayed oil is scattered around and adheres to the glass on the wall surface of the hoistway, passengers of the elevator cannot see the outside well, impairing the function of the view elevator.

Further, as described above, the worker refuels within the reach of the stopped elevator car, but depending on the vertical relationship between the worker and the part of the main wire rope to be refueled, the main wire The amount of oil adhered varies in the length direction of the rope. As a result, there is a problem that the amount of oil supply is insufficient in a portion of the main wire rope, smooth operation of the elevator cannot be ensured, and durability of the main wire rope is reduced. Furthermore, there is a problem that the amount of oil supplied is too large in a portion of the main wire rope, and the oil is wasted.

Further, as described above, since the worker extends his hand from above the elevator car to refuel, the direction in which the refueling spray can approach the main wire rope is limited to the side where the worker is. To be As a result, the rear part of the main wire rope is not sufficiently lubricated when viewed from the operator's position, and due to this insufficient lubrication amount, smooth operation of the elevator cannot be ensured, and the durability of the main wire rope is reduced. There is a problem that

Here, in order to cope with the problem that the oil cannot be sufficiently and uniformly supplied to the main wire rope as described above, a brush or the like is used to apply the oil uniformly over the entire circumference and in the longitudinal direction. It can be extended. However, in this case, such work is added and workability is deteriorated.

Further, in the conventional refueling work, there is a problem that the work takes a long time because the elevator car is moved in small increments and stopped and the main wire rope is refueled as described above.

The present invention has been made to solve the above problems, and the objects of the present invention are as follows.

Still another object of the present invention is to remove the oil sprayed from the oil supply spray and adhering to the main wire rope,
Without increasing the man-hours, it is possible to apply it evenly over the entire circumference of the main wire rope and in the lengthwise direction, and it is possible to sufficiently lubricate the rear part of the main wire rope as seen from the operator's position. To provide a main wire rope refueling jig.

Still another object of the present invention is to move the elevator car over a long distance at a time, rather than repeating the small movement and stop of the elevator car at the time of refueling work as in the conventional case, and carry out this movement. An object of the present invention is to provide a main wire rope lubrication jig capable of shortening work time by performing lubrication in the meantime.

Still another object of the present invention is that when the elevator car is moved, the main wire rope refueling jig is automatically moved, and the main wire rope is automatically refueled. An object of the present invention is to provide a main wire rope lubrication jig capable of improving the oil supply.

That is, the injection button operating lever provided on the elevator car and the jig body during the fueling operation is connected by the pulling wire. When the elevator car is stopped, the elevator main wire rope refueling jig is stopped and the injection button operating lever is not operated. Here, when the elevator car moves down, the elevator main wire rope refueling jig is pulled downward through the pulling wire and moves. At the same time, the traction wire rotates the injection button operation lever so as to pull it down, and the operation lever depresses the oil injection button to inject oil. Next, when the elevator car stops, the elevator main wire rope fueling jig also stops being pulled and stopped. Further, the stopping of the elevator car weakens the force with which the pulling wire pulls down the injection button operating lever. As a result, the oil injection button pushes up the injection button operating lever by the reaction force of the button itself and returns to the original position, and thus the oil injection is stopped.
