[0026] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0027] The utility model proposes a ball mill hydraulic intelligent gear alignment system, such as Figure 1-4 As shown, it comprises a ball mill body 1, a slow drive device 7 is arranged at one end of the cylinder of the ball mill body 1, a power output end of the slow drive device 7 is connected to a drive shaft 8, the drive shaft 8 is placed inside the cylinder of the ball mill body 1, a driven shaft 10 is movably sleeved on the outer wall of the drive shaft 8, a drive gear 13 is arranged at the end of the driven shaft 10, the drive gear 13 is located at the other end of the cylinder of the ball mill body 1, and a limit ring 12 is fixed to the outer wall of the driven shaft 10;

[0028] A hydraulic cylinder 2 is provided on the side of the ball mill body 1, and a push plate 3 is connected to one end of the hydraulic cylinder 2 close to the driving gear 13, a push ring 6 is fixed to the middle of the push plate 3, and the push ring 6 is rotatably connected to the outer wall of the driven shaft 10, and the limit ring 12 is located between the push ring 6 and the driving gear 13. Fixed rods 4 with an inner cavity for setting an identification camera 5 are installed on both side plates of the push plate 3, and the identification camera 5 is aimed at the driving gear 13;

[0029] The identification signal output end of the identification camera 5 is connected to the signal input end of the controller, and the signal output end of the controller is respectively connected to the signal input end of the hydraulic station and the signal input end of the slow drive device 7, and the signal output end of the hydraulic station is connected to the signal input end of the hydraulic cylinder 2.

[0030] During the use of the system of the present invention, when it is necessary to drive the ball mill slowly, the tooth profile on the outer wall of the driving gear 13 and the tooth profile on the outer wall of the main shaft (the main shaft refers to the rotating shaft that rotates inside the ball mill for grinding) are first scanned and identified by the identification camera 5. When the tooth profiles correspond, the hydraulic station can be driven by the controller, so that the hydraulic cylinder 2 is extended and retracted, and the push plate 3 is pushed outward. At this time, the driven shaft 10 will move outward under the action of the pushing ring 6 and the limit ring 12. In the process of the equipment moving outward, the outer wall of the driving gear 13 will dock with the main shaft. When the docking is completed, the slow driving device 7 can be started by the controller, so that the slow driving device 7 drives the main shaft to rotate slowly; if it is found that the teeth on the outer wall of the driving gear 13 do not correspond to the teeth on the main shaft under the scanning and identification of the identification camera 5, the hydraulic cylinder 2 will not start at this time, and it is necessary to adjust the angle of the driving gear 13 under the action of the slow driving device 7. After the adjustment is completed, the hydraulic cylinder 2 can be started after scanning and identification again, and the driving gear 13 can be pushed to move and dock.

[0031] In the preferred embodiment of the ball mill hydraulic intelligent gear alignment system described in the utility model, Figure 5 As shown, a driving groove 9 is opened on the outer wall of the driving shaft 8, and a driving plate 11 is fixed to the inner wall of the driven shaft 10. The positions of the driving groove 9 and the driving plate 11 correspond one to one, and the width of the driving groove 9 is equal to the width of the driving plate 11, and the length of the driving groove 9 is greater than the length of the driving plate 11.

[0032] By opening a driving groove 9 on the outer wall of the driving shaft 8 and fixing a driving plate 11 on the inner wall of the driven shaft 10, when the driven shaft 10 is on the outer wall of the driving shaft 8, the driving plate 11 will slide in the inner cavity of the driving groove 9, so that the driven shaft 10 can move from the outer wall of the driving shaft 8, and under the action of the driving plate 11 and the driving groove 9, when the driving shaft 8 rotates, the driven shaft 10 can be driven to rotate, so that the driven shaft 10 can rotate under the drive of the driving shaft 8, thereby driving the main shaft to rotate under the action of the driving gear 13.

[0033] In the specific implementation of the ball mill hydraulic intelligent gear alignment system described in the utility model, a limit ring 12 is provided on the outer wall of the driven shaft 10, the inner diameter of the limit ring 12 is equal to the outer diameter of the driven shaft 10, and the push ring 6 is located between the limit ring 12 and the driving gear 13.

[0034] The push plate 3 can be pushed forward by the hydraulic cylinder 2. In the process of the push plate 3 moving forward, the driven shaft 10 can be driven to move outward by the push ring 6 and the limit ring 12, so as to adjust the position of the driven shaft 10 so as to better contact the driving gear 13 with the main shaft teeth.

[0035] In the preferred embodiment of the ball mill hydraulic intelligent gear alignment system described in the utility model, Figure 3 As shown, there are two limiting rings 12 , and the limiting rings 12 are fixedly mounted on the outer wall of the driven shaft 10 , and the pushing ring 6 is located between the two limiting rings 12 .

[0036] By fixing two limit rings 12 on the outer wall of the driven shaft 10, the push ring 6 is located between the two limit rings 12, so that when the hydraulic cylinder 2 pushes the push plate 3 to move forward, the driven shaft 10 can be driven to move outward under the action of the push plate 3 and the push ring 6.

[0037] In a preferred embodiment of the hydraulic intelligent gear alignment system for a ball mill described in the utility model, the width of the push ring 6 is equal to the distance between the inner rings of the two limit rings 12, so that the outer wall of the push ring can be completely fitted with the limit ring without deviation. Therefore, when the push ring moves a certain distance, the distance moved by the limit ring and the driven shaft is consistent with the distance moved by the push ring, so as to ensure that the driving gear on the outer wall of the driven shaft can be accurately docked with the main shaft of the ball mill.

[0038] In a specific implementation of the ball mill hydraulic intelligent gear alignment system of the utility model, the inner diameter of the push ring 6 is equal to the outer diameter of the driven shaft 10 .

[0039] In a specific embodiment of the ball mill hydraulic intelligent gear alignment system described in the utility model, the length of the driving groove 9 is greater than the maximum extension length of the hydraulic cylinder 2, and the inner wall diameter of the driven shaft 10 is equal to the outer wall diameter of the driving shaft 8.

[0040] Through the driving groove 9 opened on the outer wall of the driving shaft 8, when the driven shaft 10 is sleeved on the outer wall of the driving shaft 8, the driving plate 11 is just located in the inner cavity of the driving groove 9. At this time, if the driving shaft 8 rotates, the driven shaft 10 can be driven to rotate under the action of the driving groove 9 and the driving plate 11, and when the hydraulic cylinder 2 pushes the push plate 3 to move outward, the driving plate 11 will slide in the inner cavity of the driving groove 9, so as to better transmit power to the driven shaft 10.

[0041] In the specific implementation of the ball mill hydraulic intelligent gear alignment system described in the utility model, the fixed rod 4 is L-shaped, wherein the part of the fixed rod 4 perpendicular to the push plate 3 is fixedly connected to the push plate 3, and the outer side of the part of the fixed rod 4 parallel to the push plate 3 is on the same horizontal line with the edge of the driving gear 13.

[0042] By setting a limit ring 12 on the outer wall of the driven shaft 10, when the position of the driven shaft 10 needs to be adjusted, the hydraulic cylinder 2 is started, and the push plate 3 is pushed to move under the action of the hydraulic cylinder 2, so as to adjust the position of the driven shaft 10. Moreover, by setting a fixed rod 4 on the outer wall of the push plate 3 and an identification camera 5 in the inner cavity of the fixed rod 4, the position and angle of the driving gear 13 are identified and scanned in real time under the action of the identification camera 5.

[0043] In a specific embodiment of the ball mill hydraulic intelligent gear alignment system described in the utility model, the system also includes a visual processing device, which is connected to the recognition camera 5, and the signal processing output end of the visual processing device is connected to the signal input end of the controller.

[0044] By means of a controller arranged on the outer wall of the ball mill body 1, the rotation of the slow drive device 7 is controlled under the action of the controller. When the ball mill needs to be driven slowly, the tooth shape of the outer wall of the main shaft and the driving gear 13 is firstly identified by the visual system under the action of the identification camera 5, and the data identified by the camera is transmitted to the server side by using the industrial identification camera 5G network. After processing the data, the server starts the hydraulic station through the controller, and the hydraulic push rod pushes the push plate 3 forward, thereby completing the docking of the driving gear 13 with the main shaft.

[0045] In the preferred embodiment of the ball mill hydraulic intelligent gear alignment system described in the utility model, two hydraulic cylinders 2 are symmetrically arranged on both sides of the ball mill body 1, and one end of the two hydraulic cylinders 2 close to the driving gear 13 is symmetrically connected to the left and right side plates of the push plate 3. Through the two symmetrically arranged hydraulic cylinders 2, the hydraulic cylinders 2 push the push plate 3 to move more smoothly, and the subsequent position adjustment of the driven shaft 10 and the recognition camera 5 to recognize and scan the position and angle of the driving gear 13 in real time are more accurate.
