[Prior art]

 2. Description of the Related Art Conventionally, there is known an oil coating device as shown in FIG. 6 which supplies a predetermined required amount of oil to prevent friction of a crane device (see Japanese Utility Model Laid-Open No. 57-111771). In the oil coating device of FIG. 6, a fixed amount of liquid oil is transferred to a tank 3, and this oil is sucked up by an oil-absorbing oil-conducting medium 4 such as felt by a capillary suction phenomenon to separate it. The roller 7 is brought to a position and the end of the felt 4 is brought into contact with the oil-painting roller 7 to slightly lubricate the roller 7, while the roller 7 is brought into contact with the side of the rail R to adhere to the roller 7. The applied oil is transferred, whereby the minimum required amount of oil is applied to the rail R and the wheel surface in contact with the rail R. This oiling device is particularly characterized in that the amount of oil supply is limited by utilizing the capillary suction phenomenon of felt.

[Problems to be solved by the device]

 However, in the conventional oil coating device as shown in FIG. 6, since the liquid oil is supplied to the rail R via the felt 4 and the roller 7, the liquid oil is scattered during the oil coating process. Then, there was a problem that the surroundings became dirty with oil. Further, in such a conventional oil coating device, there is a problem that the structure is complicated and the manufacturing cost is increased because it is necessary to interpose the oil absorbing medium 4 such as felt. The present invention has been made by paying attention to such conventional problems, and in the process of applying the lubricant, the lubricant does not scatter and the surroundings are contaminated, and the structure is simple and the cost is low. An object of the present invention is to provide a lubricant coating device that can be manufactured.

[0005]

[Action]

 As described above, in the lubricant applying device according to the present invention, a viscous lubricant is stored in the lubricant container, the lubricant is exposed from the opening of the container, and the exposed lubricant is rotated. It is transferred to the body, and then it is moved to frictional parts such as rails through this rotating body. Therefore, since the lubricant is viscous, there is no risk that the lubricant will scatter around during application, and the inconvenience of being contaminated with scattered oil or the like as in the conventional case is eliminated. Further, unlike the conventional case, it is not necessary to provide a member such as felt for moving and transmitting the liquid oil to the roller that comes into contact with the rail, so that the number of parts can be reduced and the configuration can be simplified. The manufacturing cost can be reduced. Further, by providing the lubricant container with an outflow prevention member such as a felt sheet above the opening, the outflow of the lubricant from the opening can be effectively prevented. Further, particularly in the present invention, the rotating body is supported by an overhead crane in a factory, and the rotating body is interposed between the lubricant container and the rail for the moving wheel. It is possible to avoid problems such as the problem that the lubricating oil is scattered below the cab mobile crane in the factory and the products and parts below are contaminated.

【Example】

 The present invention will be described below based on the illustrated embodiments. FIG. 1 is a perspective view showing a lubricant applying device according to an embodiment of the present invention. This lubricant coating device is mounted on an overhead crane as shown in FIGS. 2 and 3, for example. First, the cab-movable ceiling crane traveling in a steel factory or the like shown in FIGS. 2 and 3 will be described. As shown in FIG. 2, this overhead crane traverses a traverse rail 15 running in a factory along the traverse rail 15 (while being guided by a guide rail 18). Further, as shown in FIG. 3, in this ceiling crane 11, the operator enters into the cab 12 from the stairs 13, and the operator operates the crane 11 while looking down from the cab 12. It has become. The overhead crane 11 is moved by wheels 16 traveling on the traverse rail 15. Reference numeral 19 is a saddle.

Since such a traverse overhead crane 11 generally has a very high operating rate, the traverse rail 15 and the flange portions of the wheels 16 are highly worn, and a traverse current collector of a cable bear type is particularly used. In such a crane, only one side on the side pulled by the club is extremely worn, so that it is particularly required to reduce the frictional resistance between the traverse rail 15 and the side surface of the wheel flange. Next, with reference to FIG. 1, the lubricant applying device of this embodiment will be described. In FIG. 1, reference numeral 15 indicates the traverse rail described above in FIG. 2 and the like, and reference numeral 16 indicates a wheel. In this embodiment, the upper end of the spring 21 is fixed to the overhead crane 11 by bolting or the like. On the other hand, the application roller 22 is fixed to the lower end of the spring 21. Therefore, the application roller 22 is suspended and supported by the spring 21 so as to be freely rotatable with respect to the overhead crane 11. Further, as will be described later in detail with reference to FIG. 5, the coating roller 22 is rotatably mounted on a base 23, and a tank 24 containing grease is fixed to the base 23. Therefore, the coating roller 22 is rotatably provided to the tank 24 via the base 23.

Further, in the present embodiment, the upper end of the spring 21 is fixed on a vertical line substantially at the center of the rail 15. Further, the coating roller 22 is supported by the spring 21 so as to contact the flange side surface of the rail 15. Therefore, the spring 21 has an elastic force generated in the direction in which the lower end moves toward the rail 15 with the fixed upper end serving as a fulcrum. Therefore, as shown in the front view of FIG. 4, the application roller 22 attached to the lower end of the spring 21 is biased by the spring 21 in the direction of the flange side surface of the rail 15.

Further, FIG. 5 is an exploded perspective view for further illustrating the configuration of the present embodiment. In FIG. 5, the lower end 21a of the spring 21 is fixed to the shaft 28 by welding or the like. Further, in this embodiment, the coating roller 22 uses a ball bearing. The shaft 28 is inserted into and fixed to the inner ring 22a of the coating roller (ball bearing) 22. Further, the lower end 28a of the shaft 28 is fixed to the base 23 with a screw (or a hole may be formed in the base 23 and the shaft 28 may be inserted into the hole and fixed by welding). As described above, the outer ring 22b of the coating roller (ball bearing) 22 faces the opening 24a of the tank 24 fixed to the base 23 and comes into contact with the grease exposed in the opening 24a. Further, in this embodiment, a felt sheet 32 is provided above the opening 24a of the inner wall of the tank 24 containing the grease. The felt sheet 32 prevents grease from flowing out through the opening 24a. Further, in this embodiment, the upper end 21b of the spring 21 is welded and fixed to the iron plate 30, and the iron plate 30 is fixed to the overhead crane 11. As a result, the spring 21, the coating roller 22, the base 23, and the tank 24 are supported by the moving overhead crane 11 in a suspended state.

Next, with reference to FIGS. 1 to 5, the operation of the lubricant application device of this embodiment will be described. First, when the overhead crane 11 as described in FIGS. 2 to 3 moves on the traverse rail 15, the coating roller 22 moves together with the overhead crane 11. Moreover, in this case, the coating roller 22 rotates while contacting the flange side surface of the rail 15 while being biased by the spring 21 toward the rail 15. On the other hand, the grease stored in the tank 24 is gradually guided by its own weight from the inside of the tank 24 to the opening 24a, and the guided grease comes into contact with the outer ring 22b of the rotating coating roller 22, and the An appropriate amount moves to the outer ring 22b. An appropriate amount of the grease that has moved to the outer ring 22b is applied to the flange side surface 15 while the outer ring 22b of the application roller 22 makes contact with the flange side surface of the traverse rail 15 while rotating (for example, a thin thickness of 20 to 30 μm). A film of grease is applied to the side surface 15 of the flange).

Although the present embodiment shows an example in which the crane is mounted on the overhead crane 11 in the factory and grease is applied to the traverse rail, the present invention is not limited to this, and the wheel of a general vehicle is used. Of course, it can also be used to prevent wear on the rails and rails. Further, in this embodiment, the spring 21 is used to urge the coating roller 22 toward the rail 15, but as the spring 21, another urging member such as a leaf spring may be used. Further, in this embodiment, the spring 21, the coating roller 22 and the tank 24 are connected via the base 23, but in the present invention, for example, the shaft 28 inserted into the coating roller 22 is welded to the tank. Thus, the base 23 may be eliminated and the spring and the tank may be directly fixed (not through the base).

[Effect of device]

 As described above, in the lubricant applying device according to the present invention, a viscous lubricant is stored in the lubricant container, the lubricant is exposed from the opening of the container, and the exposed lubricant is removed from the rotary body. Then, it is moved to a rubbing site such as a rail through this rotating body. Therefore, since the lubricant is viscous, there is no risk of the lubricant being scattered around during application, and the inconvenience of being contaminated with scattered oil or the like unlike the conventional case is eliminated. In addition, unlike the conventional method, it is not necessary to provide a member such as felt to move and transfer the liquid oil to the roller that contacts the rail, so the number of parts of the coating device can be reduced and the configuration is simplified. Therefore, the manufacturing cost can be reduced. Further, by providing the lubricant container with an outflow prevention member such as a felt sheet above the opening, the outflow of the lubricant from the opening can be effectively prevented. Further, particularly in the present invention, the rotating body is supported by an overhead crane in a factory, and the rotating body is interposed between the lubricant container and the rail for the moving wheel. It is possible to avoid problems such as the problem that the lubricating oil is scattered below the cab mobile crane in the factory and the products and parts below are contaminated.
