Its weight accounts for about 40% of the total weight of all equipment in the rolling mill workshop and is the most used equipment in the rolling mill workshop. The work of rolled pieces entering and leaving the heating furnace, reciprocating rolling on the rolling mill, and being transported to the finishing process after rolling are all completed by the roller table. The heating furnace discharging roller table is a key equipment for billets to enter the rolling mill and directly affects the production rhythm of the entire workshop to a large extent. In the actual use process of the existing discharging roller table, the bearing seats of the roller table at the discharging door are baked by high temperature for a long time, and the lubricating grease added is consumed too fast, unable to normally meet the lubrication requirements of the bearing seats, resulting in the phenomena of bearing seat jamming and seizure of the roller table, seriously affecting the production rhythm. Therefore, it is necessary to develop a lubrication device for a heating furnace discharging roller table to ensure the lubrication requirements of the bearing seats and solve the problems of bearing seat jamming and seizure of the roller table.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The present utility model will be further described below with reference to the drawings, but the present utility model is not limited in any way. Any change or improvement made based on the teachings of the present utility model falls within the protection scope of the present utility model.

[0015] As Figures 1 to 4 shown, the utility model includes a bearing seat and a roller 15. The bearing seat is composed of a base 1, a bearing housing 2, balls 3 and a roller shaft 4. The roller shaft 4 is integrally formed with the roller 15. A cavity 5 is provided on the outer side surface of the bearing housing 2 parallel to the roller shaft 4. The outer side surface of the bearing housing 2 parallel to the roller shaft 4 is seamlessly connected to the cavity 5. The cavity 5 is connected with a cooling water pipe 9. One end of the cooling water pipe 9 is connected with a cooling water pump 10, and the other end is connected with a cooling water return pool 11. The cooling water pump 10 pumps cold water into the cavity 5 on the outer surface of the bearing housing 2. After the cooling water exchanges heat with the bearing seat, it flows into the cooling water return pool 11. By the continuous flow of the cooling water, the bearing seat is cooled. On the two side surfaces of the bearing seat perpendicular to the roller shaft 4, annular oil storage pipes 7 are respectively provided. The annular oil storage pipes 7 are welded to the bearing housing 2. Nozzles 71 are provided on the side of the annular oil storage pipes 7 close to the bearing seat. The annular oil storage pipes 7 are connected with an oil supply pipe 6. The oil supply pipe 6 is connected with a lubricating oil pump 13. The lubricating oil pump 13 pumps lubricating oil into the annular oil storage pipes 7 through the oil supply pipe 6. By the continuous pumping of the lubricating oil pump 13, the pressure in the annular oil storage pipes 7 continuously increases. When the pressure reaches a certain pressure value, the lubricating oil in the annular oil storage pipes 7 is sprayed onto the balls 3 of the bearing seat through the nozzles 71. And annular oil storage pipes 7 are respectively provided on the two side surfaces of the bearing seat perpendicular to the roller shaft 4. The lubricating oil in the annular oil storage pipes 7 on the two side surfaces is sprayed out simultaneously, and the lubricating oil is sprayed without dead corners, ensuring the lubrication effect.

[0016] A through hole is provided at the bottom of the bearing housing 2. An excess oil recovery pipe 8 is provided below the through hole at the bottom of the bearing housing 2. The excess oil recovery pipe 8 is connected with an excess oil recovery pool 12. The excess lubricating oil sprayed onto the balls 3 of the bearing seat by the nozzles 71 flows along the bearing housing 2 or the balls 3 to the bottom of the bearing housing 2, then flows into the excess oil recovery pipe 8 through the through hole at the bottom of the bearing housing 2, and finally flows into the excess oil recovery pool 12 for recycling.

[0017] The lubricating oil pump 13 is connected with a timing switch 14. The time from starting the lubricating oil pump 13 to spraying the lubricating oil onto the balls 3 of the bearing seat is fixed. The time for spraying the lubricating oil onto the balls 3 is also fixed, and the interval time between each spraying is also controllable. By setting the corresponding time through the timing switch 14, the automatic lubrication of the roller way lubrication device can be realized, reducing the labor intensity of personnel.

[0018] The annular oil storage pipe 7 is circular. The inner diameter of the annular oil storage pipe 7 is equal to the diameter of the roller shaft 4. One side of the annular oil storage pipe 7 close to the bearing housing is a plane. The nozzle 71 is arranged on the plane of the annular oil storage pipe 7 close to the bearing housing. The annular oil storage pipe 7 is perpendicular to the bearing housing and is seamlessly connected to the two side surfaces of the roller shaft 4, preventing foreign matters such as dust and particulate matters from entering the bearing housing. Moreover, the sprayed lubricating oil is sealed in the bearing housing and will not pollute the surrounding environment. The nozzles 71 are evenly distributed at the inner or outer edge of the plane of the annular oil storage pipe 7. The position of the nozzle 71 corresponds to the gap of the ball 3. The ball 3 is a spherical body, and a plurality of balls 3 enclose a circle along the inner side of the bearing housing 2. The balls 3 are in spherical contact with each other. The gap between the maximum diameter and the minimum diameter of the enclosed circle is the largest. The nozzles 71 are evenly distributed at the inner or outer edge of the plane of the annular oil storage pipe 7 and just correspond to the gap between the balls 3. When the lubricating oil is sprayed out from the nozzle 71, it can not only be sprayed into the gap between the balls 3, but also be sprayed on the spherical surface of the ball 3, further ensuring the lubrication effect.

[0019] During use, set the timing switch 14 to a certain time, and at the same time start the cooling water pump 10. The cooling water pump 10 pumps cold water into the cooling water pipe 9. The cold water flows into the cavity 5 along the cooling water pipe 9. After the cooling water exchanges heat with the bearing housing in the cavity 5, it then flows into the cooling water return pool 11 through the cooling water pipe 9. When the timing switch 14 reaches the set time, the lubricating oil pump 13 is automatically started. The lubricating oil pump 13 pumps the lubricating oil into the oil supply pipe 6. The lubricating oil enters the annular oil storage pipe 7 along the oil supply pipe 6. As the lubricating oil is continuously pumped in, the pressure in the annular oil storage pipe 7 becomes higher and higher. When it reaches a certain pressure value, the lubricating oil in the annular oil storage pipe 7 is sprayed from the nozzle 71 onto the balls 3 of the bearing housing. When the spraying time ends, the timing switch automatically closes, the lubricating oil pump 13 stops, the pressure in the annular oil storage pipe 7 decreases, and the lubricating oil spraying stops. The excess sprayed lubricating oil flows along the bearing housing 2 or the balls 3 to the bottom of the bearing housing 2, and then flows into the surplus oil recovery pipe 8 through the through hole at the bottom of the bearing housing 2, and finally flows into the surplus oil recovery pool 12 for recycling.
