Description

Technical Field

[0001] The invention relates to the technical field of cooling bed lubrication, in particular to an automatic lubrication device for an eccentric wheel of a cooling bed. Background Art

[0002] In the production process of straight bar products, the bars are usually cooled by a walking cooling bed, and the eccentric wheels in the walking cooling bed are mostly lubricated by an oil pool.

[0003] In the related art, a Chinese patent with authorization announcement number CN214699133U provides an automatic lubrication device for a coking eccentric wheel, which includes a lubrication groove, a lubricating medium in the lubrication groove, an eccentric wheel outer seat above the lubrication groove, an eccentric wheel rotating in the eccentric wheel outer seat, and a part of the eccentric wheel is located in the lubrication groove. When the eccentric wheel rotates, the outer wall of the eccentric wheel contacts the lubricating medium in the lubrication groove, thereby lubricating the eccentric wheel.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology: since the lubrication groove is installed below the rack surface of the cooling bed, when the cooling bed is working, the operators are prohibited from entering this area to add lubricating medium into the lubrication groove, so the lubrication effect of the eccentric wheel is easily deteriorated. When the cooling bed is not in operation, the operators check the lubrication grooves one by one and add lubricating medium. Due to the large number of lubrication grooves and the high temperature under the cooling bed, the labor intensity of the operators is increased. Summary of the invention

[0005] In order to facilitate the addition of lubricating oil into the lubrication groove and reduce the labor intensity of operators, the present application provides an automatic lubrication device for the eccentric wheel of a cooling bed.

[0006] The present application provides an automatic lubrication device for the eccentric wheel of a cooling bed, which adopts the following technical solution:

[0007] An automatic lubrication device for an eccentric wheel of a cooling bed comprises a plurality of lubrication grooves, wherein an upper cavity, a middle cavity and a lower cavity are arranged in the lubrication groove, the upper cavity, the middle cavity and the lower cavity are connected to each other, the upper cavity is located above the middle cavity, the middle cavity is located above the lower cavity, an oil supply branch pipe is arranged on the lubrication groove, one end of the oil supply branch pipe is connected to the lower cavity, the other end of the oil supply branch pipe is connected to an oil supply main pipe, an oil supply tank is connected to the oil supply main pipe, the inner wall of the oil supply main pipe is flush with the inner bottom wall of the oil supply tank, and an oil inlet pipe is connected to the top of the oil supply tank.

[0008] By adopting the above technical scheme, the bottom of the eccentric wheel is located in the middle cavity of the lubrication groove. During the rotation of the eccentric wheel, the outer wall of the eccentric wheel contacts the lubricating oil in the lubrication groove, and then the lubricating oil adheres to the outer wall of the eccentric wheel to achieve the lubrication effect of the eccentric wheel. Since the oil supply tank and the lower cavity of the lubrication groove are interconnected through the oil supply branch pipe and the oil supply main pipe, the lubricating oil in the oil supply tank and the lubrication groove are at the same liquid level. When the lubricating oil in the lubrication groove needs to be replenished, the lubricating oil is injected into the oil supply tank through the oil inlet pipe, and the lubricating oil in the oil supply tank flows into the lubrication groove through the oil supply main pipe and the oil supply branch pipe. In the above manner, the operator can replenish the lubricating oil to the lubrication groove during the operation of the cooling bed, and reduce the situation where the operator adds lubricating oil to the lubrication groove one by one, thereby achieving the effect of facilitating the addition of lubricating oil to the lubrication groove and reducing the labor intensity of the operator.

[0009] Preferably, a group of oil baffle side plates and a group of oil baffle end plates are fixedly arranged on the top of the lubrication groove, the oil baffle side plates are arranged opposite to each other, the oil baffle end plates are arranged opposite to each other, the side walls of adjacent oil baffle side plates and oil baffle end plates are tightly fitted, the bottom of the oil baffle side plate and the bottom of the oil baffle end plate jointly form a lower opening, the top of the oil baffle side plate and the top of the oil baffle end plate jointly form an upper opening, and the diameter of the upper opening is larger than the diameter of the lower opening.

[0010] By adopting the above technical solution, the oil-blocking side plate and the oil-blocking end plate form a shield around the eccentric wheel, thereby preventing the lubricating oil in the lubrication groove from dripping to the outside.

[0011] Preferably, a clearance groove is provided on the top of the oil baffle side plate, and the clearance groove runs through the side wall of the oil baffle side plate.

[0012] By adopting the above technical solution, the recess is provided for the drive shaft on the deflection wheel to be inserted.

[0013] Preferably, an overflow branch pipe is arranged on the lubrication groove, one end of the overflow branch pipe is interconnected with the upper cavity, the other end of the overflow branch pipe is connected to an overflow main pipe, and the overflow main pipe is connected to an oil storage tank.

[0014] By adopting the above technical solution, when the lubricating oil in the lubrication groove enters the upper chamber, the lubricating oil in the upper chamber flows into the overflow main pipe through the overflow branch pipe, and the lubricating oil in the overflow main pipe flows into the oil storage tank for storage, thereby reducing the overflow of the lubricating oil in the lubrication groove.

[0015] Preferably, an upper oil chamber, a middle oil chamber and a lower oil chamber are arranged in the oil storage tank, and the upper oil chamber, the middle oil chamber and the lower oil chamber are connected to each other. The upper oil chamber is located above the middle oil chamber, and the middle oil chamber is located above the lower oil chamber. The overflow main pipe is connected to the upper oil chamber, and the lower oil chamber is connected to the oil inlet pipe.

[0016] By adopting the above technical solution, the lubricating oil in the overflow main pipe is injected into the oil storage tank from the upper oil chamber, and the lubricating oil gradually accumulates in the oil storage tank from the lower oil chamber to the upper oil chamber. When the lubricating oil in the lubrication groove is insufficient, the lubricating oil in the oil storage tank flows from the lower oil chamber to the oil inlet pipe, and then the lubricating oil in the oil storage tank is injected into the oil supply tank.

[0017] Preferably, an oil feed pump is fixedly arranged on the oil supply tank, the output end of the oil feed pump is interconnected with the end of the oil feed pipe away from the oil supply tank, the input end of the oil feed pump is connected to a refueling pipe, and the refueling pipe is interconnected with the lower oil chamber.

[0018] By adopting the above technical solution, when the lubricating oil in the lubrication groove is insufficient, the oil inlet pump is started, and the oil inlet pump draws the lubricating oil in the oil storage tank from the lower oil chamber to the filling pipe, and the lubricating oil in the filling pipe is pumped into the oil inlet pipe, and the lubricating oil in the oil inlet pipe flows into the oil supply tank.

[0019] Preferably, an oil delivery hole is opened on the top of the oil storage tank, and the oil delivery hole is interconnected with the upper oil chamber. A second liquid level gauge is commonly arranged in the upper oil chamber, the middle oil chamber and the lower oil chamber, and the second liquid level gauge is used to detect the liquid level inside the oil storage tank.

[0020] By adopting the above technical solution, the second liquid level gauge detects the liquid level inside the oil storage tank. When the second liquid level gauge detects that the liquid level is lower than the set minimum liquid level, the operator injects lubricating oil into the oil storage tank through the oil delivery hole.

[0021] Preferably, a first liquid level gauge is provided in the oil supply tank, and the first liquid level gauge is used to detect the liquid level inside the oil supply tank.

[0022] By adopting the above technical scheme, the first liquid level gauge detects the liquid level of the lubricating oil in the oil supply tank. Since the lubricating oil in the oil supply tank and the lubrication groove are at the same liquid level, the liquid level gauge detected by the first liquid level gauge is the liquid level of the lubricating oil in the lubrication groove. When the first liquid level gauge detects that the liquid level is lower than the set minimum liquid level, it means that the lubricating oil in the lubrication groove is insufficient, thereby reducing the situation where the staff observes the liquid level of the lubricating oil in the lubrication groove, so that the staff can replenish the lubricating oil in the lubrication groove in time.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The present application embodiment discloses an automatic lubrication device for an eccentric wheel of a cooling bed. Figures 1 to 4, including a plurality of lubrication grooves 1, wherein an upper cavity 11, a middle cavity 12 and a lower cavity 13 are arranged in the lubrication groove 1. The upper cavity 11, the middle cavity 12 and the lower cavity 13 are interconnected, the upper cavity 11 is located above the middle cavity 12, and the middle cavity 12 is located above the lower cavity 13. An oil supply branch pipe 21 is installed at one end of the lubrication groove 1, one end of the oil supply branch pipe 21 is interconnected with the lower cavity 13, and the other end of the oil supply branch pipe 21 is connected to the oil supply main pipe 2. The oil supply main pipe 2 is connected to the oil supply tank 3, the inner wall of the oil supply main pipe 2 is flush with the inner bottom wall of the oil supply tank 3, and the top of the oil supply tank 3 is connected to the oil inlet pipe 41. The bottom of the eccentric wheel 9 is installed in the middle cavity 12 of the lubrication groove 1. During the rotation of the eccentric wheel 9, the outer wall of the eccentric wheel 9 contacts the lubricating oil in the lubrication groove 1, and then the lubricating oil adheres to the outer wall of the eccentric wheel 9 to achieve the lubrication effect of the eccentric wheel 9. Since the oil supply tank 3 and the lower chamber 13 of the lubrication groove 1 are interconnected through the oil supply branch pipe 21 and the oil supply main pipe 2, the lubricating oil in the oil supply tank 3 and the lubrication groove 1 are at the same liquid level. When the lubricating oil in the lubrication groove 1 needs to be replenished, the lubricating oil is injected into the oil supply tank 3 through the oil inlet pipe 41, and the lubricating oil in the oil supply tank 3 flows into the lubrication groove 1 through the oil supply main pipe 2 and the oil supply branch pipe 21. In the above manner, the operator can replenish the lubricating oil into the lubrication groove 1 during the operation of the cooling bed, and reduce the situation where the operator adds the lubricating oil to the lubrication groove 1 one by one, thereby achieving the effect of facilitating the addition of lubricating oil to the lubrication groove 1 and reducing the labor intensity of the operator.

[0036] In order to prevent the lubricating oil in the lubrication groove 1 from dripping to the outside, refer to Figures 1 to 3 A group of oil-blocking side plates 8 and a group of oil-blocking end plates 81 are installed on the top of the lubrication groove 1. The oil-blocking side plates 8 are arranged opposite to each other, and the oil-blocking end plates 81 are arranged opposite to each other, and the side walls of adjacent oil-blocking side plates 8 and oil-blocking end plates 81 fit tightly. A clearance groove 84 is provided on the top of the oil-blocking side plate 8, and the clearance groove 84 runs through the side wall of the oil-blocking side plate 8. The bottom of the oil-blocking side plate 8 and the bottom of the oil-blocking end plate 81 jointly form a lower opening 83, and the top of the oil-blocking side plate 8 and the top of the oil-blocking end plate 81 jointly form an upper opening 82, and the diameter of the upper opening 82 is larger than that of the lower opening 83. The transmission shaft 91 on the deflection wheel is inserted into the clearance groove 84, and the oil-blocking side plates 8 and the oil-blocking end plates 81 form a shield around the eccentric wheel 9. During the rotation of the eccentric wheel 9, the situation where the eccentric wheel 9 drives the lubricating oil in the lubrication groove 1 to drip to the outside is reduced.

[0037] In order to reduce the overflow of lubricating oil in the lubrication groove 1, refer to Figure 1 and Figure 2An overflow branch pipe 51 is installed on one end of the lubricating groove 1 away from the oil supply branch pipe 21, one end of the overflow branch pipe 51 is connected to the upper chamber 11, and the other end of the overflow branch pipe 51 is connected to the overflow main pipe 5, and the overflow main pipe 5 is connected to the oil storage tank 6. When the lubricating oil in the lubricating groove 1 enters the upper chamber 11, the lubricating oil in the upper chamber 11 flows into the overflow main pipe 5 through the overflow branch pipe 51. The lubricating oil in the overflow main pipe 5 flows to the oil storage tank 6 for storage, thereby reducing the situation where the lubricating oil in the lubricating groove 1 overflows excessively.

[0038] In order to inject the lubricating oil in the oil storage tank 6 into the oil supply tank 3, refer to Figures 1 to 5 The oil supply tank 3 is provided with an oil feed pump 4, the output end of the oil feed pump 4 is interconnected with the end of the oil feed pipe 41 away from the oil supply tank 3, and the input end of the oil feed pump 4 is connected with a refueling pipe 42. The oil storage tank 6 is provided with an upper oil chamber 71, a middle oil chamber 72 and a lower oil chamber 73, the upper oil chamber 71, the middle oil chamber 72 and the lower oil chamber 73 are interconnected, the upper oil chamber 71 is located above the middle oil chamber 72, and the middle oil chamber 72 is located above the lower oil chamber 73. The upper oil chamber 71 is interconnected with the overflow main pipe 5, and the lower oil chamber 73 is interconnected with the refueling pipe 42. The lubricating oil in the overflow main pipe 5 is injected into the oil storage tank 6 from the upper oil chamber 71, so that the lubricating oil gradually accumulates from the lower oil chamber 73 to the upper oil chamber 71 in the oil storage tank 6. When the lubricating oil in the lubrication groove 1 is insufficient, the oil inlet pump 4 is started, and the oil inlet pump 4 draws the lubricating oil in the oil storage tank 6 from the lower oil chamber 73 to the filling pipe 42. The lubricating oil in the filling pipe 42 is then pumped into the oil inlet pipe 41, and the lubricating oil in the oil inlet pipe 41 flows into the oil supply tank 3.

[0039] In order to inject lubricating oil into the oil tank 6, refer to Figure 6 The top of the oil storage tank 6 is provided with an oil delivery hole 61, which is connected to the upper oil chamber 71. The upper oil chamber 71, the middle oil chamber 72 and the lower oil chamber 73 are equipped with a second liquid level gauge 7, which is used to detect the liquid level inside the oil storage tank 6. When the second liquid level gauge 7 detects that the liquid level is lower than the set minimum liquid level, the operator injects lubricating oil into the oil storage tank 6 through the oil delivery hole 61.

[0040] In order to facilitate the staff to observe the lubricating oil level in the lubrication groove 1, refer to Figures 1 to 4 A first liquid level gauge 31 is installed in the oil supply tank 3, and the first liquid level gauge 31 is used to detect the liquid level inside the oil supply tank 3. Since the lubricating oil in the oil supply tank 3 and the lubricating tank 1 are at the same liquid level, the liquid level height detected by the first liquid level gauge 31 is the liquid level height of the lubricating oil in the lubricating tank 1. When the first liquid level gauge 31 detects that the liquid level height is lower than the set minimum liquid level height, it means that the lubricating oil in the lubricating tank 1 is insufficient. This reduces the need for staff to directly observe the lubricating oil level height in the lubricating tank 1, allowing staff to replenish the lubricating oil in the lubricating tank 1 in a timely manner.

[0041] The implementation principle of the automatic lubrication device for the eccentric wheel 9 of the cooling bed in the embodiment of the present application is as follows: the bottom of the eccentric wheel 9 is installed in the middle cavity 12 of the lubrication groove 1. During the rotation of the eccentric wheel 9, the outer wall of the eccentric wheel 9 contacts the lubricating oil in the lubrication groove 1, and then the lubricating oil adheres to the outer wall of the eccentric wheel 9 to achieve the lubrication effect of the eccentric wheel 9. Since the oil supply tank 3 and the lower cavity 13 of the lubrication groove 1 are interconnected through the oil supply branch pipe 21 and the oil supply main pipe 2, the lubricating oil in the oil supply tank 3 and the lubricating groove 1 are at the same liquid level. When the first liquid level gauge 31 detects that the liquid level is lower than the set minimum liquid level, the lubricating oil in all the lubrication grooves 1 is insufficient, and the oil inlet pump 4 is started. The oil inlet pump 4 draws the lubricating oil in the oil storage tank 6 from the lower oil chamber 73 to the filling pipe 42, and the lubricating oil in the filling pipe 42 is pumped into the oil inlet pipe 41, and the lubricating oil in the oil inlet pipe 41 flows into the oil supply tank 3. When the first liquid level gauge 31 detects that the liquid level has reached the set maximum liquid level, the oil inlet pump 4 stops, and at this time, the middle cavity 12 and the lower cavity 13 in all the lubrication grooves 1 are filled with lubricating oil. In the above manner, the operator can add lubricating oil to the lubrication groove 1 during the cooling bed operation, and the operator can add lubricating oil to the lubrication groove 1 one by one, thereby achieving the effect of facilitating the addition of lubricating oil to the lubrication groove 1 and reducing the labor intensity of the operator.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
