Description

Run rail oiling device for cranes {AN APPARATUS FOR OILING RAIL FOR CRANE MOVING}

The present invention relates to a device for oiling the running rail to prevent friction between the traveling rail and the wheel moving the moving portion of the crane for moving the heavy load in the factory, in particular, so as to keep only the side of the rail, driving wheel The invention relates to a crane traveling rail lubrication device which prevents the rail slipping of the traveling portion from being squeezed by the oil-tight portion of the rail and the rail, and prevents the oil-tight portion of the rail and the driving wheel from being contaminated by oil. .

In general, in large factories such as steel mills, ceiling cranes are used to move heavy structures. Such a crane lifts a moving part while moving a moving part on a rail installed at regular intervals on both side beams of the factory. do.

However, in such a overhead crane, a traveling wheel mounted on the crane traveling part is seated on the traveling rail that supports the weight of the crane itself and the load imposed on the crane, and moves forward and backward, as shown in FIG. When the traveling wheel 110 of the crane traveling unit 100 moves along the traveling rail 120, the center portion 120a of the traveling rail 120 is moved by the tolerance between the rail 120 and the wheel 110. Accordingly, the center portion 110b of the driving wheel 110 may not move, and the flange portion 110a of the driving wheel 110 and the side portion 120a of the driving rail 120 are worn while being biased toward one side. In order to prevent wear of the traveling rail and the traveling wheel flange part, although schematically illustrated in FIG. 1, the wheel 110 flange part 110a is used by using an oil lubricator 130 disposed below the crane traveling part 100. Oil).

However, as shown in FIG. 1, when the oiler 130 oils oil on the flange 110a of the traveling wheel 110, excessive oiling occurs easily, so that the crane moves. When the driving wheel 110 is rotated for the central part 110b of the wheel flange 110a and the central part 120a of the running rail 120 while excessively in oil while starting and braking the wheel of the crane traveling part 100. This causes a problem in which slip slip 110 occurs on the rail 120.

As a result, the rail 120 slip of the wheel 110 causes wear of the rail 120 and the cross-section of the wheel 110, as well as slip of the crane traveling part generated when the package moves, and the package collides with the peripheral equipment. There is a high possibility that a damage to the facility is generated, and the safety accidents of workers around.

As a result, in the related art, a worker wipes the oil-contaminated portion of the rail 120 with a rag, or moves along the rail 120, which involves cumbersome work of washing and removing oil by spraying sand. The safety accident of the same worker is concerned.

Therefore, if oil is applied only to the side portions of the rails on which the wheels of the crane traveling portions move, the rail slip phenomenon of the traveling wheels may be prevented while reducing wear of the side contact portions of the traveling rails and the wheels.

The present invention has been made in order to improve the various conventional problems as described above, the purpose of the oil to prevent the wear of the crane traveling wheels moving along the rail in order to keep oil only on the side of the running rail, driving wheel flange portion To prevent the rail slipping of the wheels while preventing contamination of rails and rails, and to prevent collisions of cargo with surrounding equipment by rail slips of cranes and to prevent accidents of workers. will be.

A second spring 72 is connected that provides an intumescent elastic force that facilitates disengagement from the rail 14.

On the other hand, as shown in Figure 2, the wire 66 is connected to the oil pipe 68 is transported in a supported state through a plurality of pulleys 74, the first installed on both sides of the base 22 The pulley 74a, the second pulley 74b installed in the center of the movable block 26, and the third pulley 74c provided at both ends of the movable block 26 toward one side of the second pulley 74b. And a fourth pulley 74d provided inside the rectangular portion of the movable bracket 28, and the wire 66 is finally connected to the movable bracket 28 through an opening 74e formed in the movable bracket 28. It is connected to oil pipe 68.

That is, as shown in FIGS. 2 and 4, the wire 66 pulls or pulls the oil conduit 68 according to the position of the movable plate 28 which moves up and down by the operation of the cylinder 30. While disappearing, the oiling roll 70 connected to the lower side of the oiling pipe 68 is in close contact with or spaced apart from the side portion 14a of the rail 14 as the moving plate 64 moves.

In addition, the oil supply pipe 68 is connected to the feeder 68b for supplying oil with a flexible hose 68c, and the oil supply roll 70 is fixed to the lower connection pipe 68a of the oil pipe 68. It consists of the configuration.

Referring to the operation and effects of the present invention made in the above configuration in more detail as follows.

At this time, as shown in FIGS. 2 and 3, when only the crane traveling portion 10 is moved, that is, when it is not necessary to oil the rails, the cylinder 30 on the base 22 provided in the traveling body 12 is provided. ) Is in the reverse state so that the moving block 26 connected to the front of the base 22 is kept horizontal with the base 22, and the front of the moving bracket 28 that is bolted to the moving block 26. The cleaning roll 42 installed in the state is separated from the upper surface of the rail 14, and similarly, the lower oil roll 70 of the oil pipe 68 positioned on the side of the moving bracket 28 is the rail 14. It is kept spaced apart from the side portion 14a.

However, when the wheel 13 of the crane traveling unit 10 is slipped when starting and stopping by the contaminated rails 14, the operator operates the control panel not shown in the drawings to operate the cylinder 30. Advance

Accordingly, as shown in FIGS. 2 to 4, the moving block 26 connected to the cylinder 30 and the connector 32 and the moving bracket 28 bolted thereto may lower the pivot 24 about the axis. As a result, as shown in FIG. 4, the cleaning roll 42 installed at the front end of the moving bracket 28 cleans the rail while being in close contact with the upper surface 14b of the moving bracket 28, and at this time, the moving block 26. And a first spring 34 connected to the elongation portion 28b of the movable bracket 28 provide an elastic force for pulling the movable bracket 26 so that the movable bracket 26 is lowered and eventually the cleaning is performed. The roll 42 is brought into closer contact with the upper surface (14b of FIG. 4) of the rail 14.

The wire 66 is connected to the oil pipe 68 through an opening 74e formed in the movable bracket 28.

Therefore, since the length of the wire 66 is constant, when the moving bracket 68 is lowered, the oil conduit 68 is deflected while the moving plate 64 provided with the oil conduit 68 is closed. It moves along the guide block 62 installed on the side of the moving bracket 28, and eventually the oil conduit 68 attached to the moving plate 64 also moves along the guide block 62 integrally.

However, as shown in FIG. 5, a second spring 72 is connected between the oil conduit 68 and the moving block 26, so that the oil pulling tube 68 is no longer pulled by the wire 66. ) Is such that the lower oil roll 70 is easily separated from the side portion 14a of the rail 14.

In addition, the oil supply pipe 68b is connected to the oil supply pipe 68 as a flexible hose 68c, and the oil supplied to the oil supply pipe 68 flows through the oil supply roll 70 along the connection pipe 68a. Oiling of the rail side portion 14a is possible, and as shown in FIG. 4, the oiling roll 70 has its rail side 14a at a fine spacing H at the upper surface 14b of the rail 14. Only oil, which flows into the upper surface 14b of the rail 14 to prevent contamination between the rail 14 and the driving wheel 13, as well as the rail 14 and the driving wheel. (13) It is to prevent the slip phenomenon.

Accordingly, when the crane traveling wheel 13 moves along the rail 14, the cleaning roll 42 descending by the operation of the cylinder 30 cleans while passing through the upper portion 14b of the rail 14 first, Then, oil is inferred only from the rail side portion 14a from the oiling roll 70 in close contact with the side portion 14a of the rail 14, thereby reducing friction between the rail side portion and the wheel flange portion, thereby preventing damage to the equipment due to wear. At the same time, the slip phenomenon that slips on the rail 14 at the start and stop of the driving wheel 13 due to contamination of the upper surface of the rail is effectively prevented.

As described above, according to the traveling rail oiling apparatus of the crane according to the present invention, since oil is inferred only on the side of the rail on which the crane traveling wheel moves, oil is not contaminated between the rail end portion and the flange portion end portion of the wheel, so that the crane starts and stops. It is possible to prevent the driving wheels from slipping on the rails.

Therefore, it is possible to prevent abnormal abrasion of rail and running wheel end surface, and to prevent equipment accidents such as collision between moving loads and surrounding equipment due to slip of crane running part, and to prevent contaminated parts of rail by manual operation. It is to provide an excellent effect to prevent the safety accidents such as stenosis and fall that can occur during removal.
