Description

Technical Field

[0001] The utility model relates to the technical field of steel casting, in particular to a graphite lubrication device for a circular cooling machine. Background Art

[0002] A circle of tracks is connected between the rotating body of the circular cooling machine and the lower part of the trolley. The tracks are in contact with the supporting rollers fixed on the frame. The rotating body and the trolley complete the rotating motion through the rolling friction between the tracks and the supporting rollers. Since the surface of the supporting rollers usually uses an oil groove arranged below the supporting rollers for lubrication, and the rotating tracks usually require the supporting rollers to lubricate them. When the lubrication of the supporting rollers is not in place, it usually causes the problem of large running resistance of the circular cooling machine.

[0003] Patent No. 2017210720417, patent name: A lubrication device for the rotating body and trolley tracks of a rotary frame type circular cooling machine, which uses graphite arranged under the rotating track through a spring for lubrication. Although the track is lubricated, in actual use, it is relatively inconvenient to replace the graphite.

[0004] Therefore, a graphite lubrication device for a circular cooling machine is needed to facilitate the replacement of graphite. Content of the Utility Model

[0005] The purpose of the utility model is to provide a graphite lubrication device for a circular cooling machine, which can conveniently replace the graphite carbon brush, and has a simple structure and is easy to use.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A graphite lubrication device for a circular cooling machine includes:

[0008] A box body, the box body is provided with a through hole, one side of the box body is provided with a fixing frame A for fixing the box body on the mounting frame of the circular cooling machine, and the other side is detachably fixed with an elastic member;

[0009] A graphite carbon brush, the graphite carbon brush is inserted into the through hole, and the elastic member abuts against the lower part of the graphite carbon brush to push it up from bottom to top so that its top passes through the through hole and abuts against the lower surface of the track to be lubricated.

[0010] A further improvement of the utility model is that the elastic member adopts a flat spiral spring.

[0011] A further improvement of the utility model is that a fixing frame B is fixed on the box body, a V-shaped elastic sheet is inserted into the fixing frame, and the elastic member is fixedly connected to one side surface of the V-shaped elastic sheet.

[0012] A further improvement of the present utility model is that a limiting groove is provided on one side of the fixing frame B away from the box body, and a limiting buckle is provided on one side surface of the V-shaped elastic piece away from the elastic member. When the V-shaped elastic piece is inserted into the fixing frame B in place, the limiting buckle is lapped on the limiting groove.

[0013] A further improvement of the present utility model is that a nut is fixed on the fixing frame A. During use, a bolt passes through the installation frame of the annular cooler and is threadedly fixed to the nut on the fixing frame A.

[0014] A further improvement of the present utility model is that the installation position of the nut on the fixing frame A protrudes downward from the box body.

[0015] The beneficial effects of the present utility model are as follows:

[0016] The present utility model fixes the fixing frame A on the installation frame through bolts. When replacing the graphite carbon brush, the V-shaped elastic piece is pinched and pulled out from the fixing frame B, so that the graphite carbon brush can be withdrawn from the bottom or a new carbon brush can be filled in and the old carbon brush can be pushed up to the track lubrication position. By setting the cooperation of the limiting buckle and the limiting groove, the installation position of the elastic member can be conveniently positioned, making the elastic member more stable.

[0018] Figure 2 is a schematic cross-sectional structural diagram of the present utility model. Detailed Embodiments

[0019] The following further clarifies the present utility model in conjunction with the drawings and specific embodiments.

[0020] Combined with Figures 1-2 it can be seen that an annular cooler graphite lubrication device includes a box body 10. The box body 10 is provided with a through hole 104. One side of the box body 10 is provided with a fixing frame A101 for fixing the box body 10 on the installation frame of the annular cooler, and an elastic member 102 is detachably fixed on the other side;

[0021] A graphite carbon brush 20 is inserted into the through hole 104. The elastic member 102 abuts against the lower part of the graphite carbon brush 20 and pushes it up from the bottom so that the top of the graphite carbon brush 20 passes through the through hole 104 and abuts against the lower surface of the track to be lubricated.

[0022] A further improvement of the present utility model is that the elastic member 102 adopts a flat spiral spring.

[0023] A further improvement of the present utility model is that a fixing frame B103 is fixed on the box body 10, a V-shaped elastic sheet 1031 is inserted into the fixing frame B103, and the elastic member 102 is fixedly connected to one side surface of the V-shaped elastic sheet 1031.

[0025] A further improvement of the present utility model is that a nut is fixed on the fixing frame A101. During use, a bolt passes through the installation frame of the annular cooler and is fixedly connected to the nut on the fixing frame A1011 by threading.

[0026] A further improvement of the present utility model is that the installation position of the nut on the fixing frame A101 protrudes downward from the box body 10.

[0027] During use, the fixing frame A is fixed to the installation frame by a bolt. When replacing the graphite carbon brush, the V-shaped elastic sheet is pinched and pulled out from the fixing frame B, so that the graphite carbon brush can be withdrawn from the bottom or a new carbon brush can be filled in and the old carbon brush can be pushed up to the track lubrication position. By setting the cooperation of the limiting buckle and the limiting groove, the installation position of the elastic member can be conveniently positioned, making the fixing of the elastic member more stable.
