[0065] Specifically, the first cover body 112 and the second cover body 114 can both be semicircular cylindrical structures, and the two ends of the first cover body 112 are respectively connected to the two ends of the second cover body 114 to enclose a cylindrical protective cover 106, wherein the two ends of the first cover body 112 and the two ends of the second cover body 114 can be connected by buckles, and a sealing portion is provided at the connection between the first cover body 112 and the second cover body 114 to prevent the lubricating oil from flowing out of the gap between the first cover body 112 and the second cover body 114. Alternatively, one end of the first cover body 112 is hinged to one end of the second cover body 114 through a hinge, and the other end of the first cover body 112 is connected to the other end of the second cover body 114 through a buckle to achieve the connection between the first cover body 112 and the second cover body 114. Further, the first oil hole 108 can be opened on the first cover body 112, and can also be opened on the second cover body 114.

[0066] By setting the first cover body 112 and the second cover body 114, a detachable connection can be achieved between the protective cover 106 and the transmission shaft 102, so that the staff can remove the protective cover 106 to check the transmission shaft 102 conveniently, and the protective cover 106 can also be removed to facilitate unblocking the first oil hole 108 when it is blocked, thereby improving the convenience of use of the drive device 100.

[0068] In this embodiment, the driving device 100 includes a first driving member 118 and a second driving member 122, wherein the output end of the first driving member 118 is connected to the first transition shaft 116, the output end of the second driving member 122 is connected to the second transition shaft 120, and the first transition shaft 116 and the second transition shaft 120 are respectively connected to the two ends of the transmission shaft 102, that is, when the first driving member 118 rotates, the transmission shaft 102 can be driven to rotate through the first transition shaft 116, and the transmission shaft 102 can also drive the second transition shaft 120 to rotate; when the second driving member 122 rotates, the transmission shaft 102 can be driven to rotate through the second transition shaft 120, and the transmission shaft 102 can also drive the first transition shaft 116 to rotate; when the first driving member 118 and the second driving member 122 rotate at the same time, the transmission shaft 102 can be driven to rotate simultaneously through the first transition shaft 116 and the second transition shaft 120 respectively. That is to say, through the connection between the first transition shaft 116, the second transition shaft 120 and the transmission shaft 102, it is possible to control the first drive member 118 and the second drive member 122 to operate simultaneously, drive the first transition shaft 116, the second transition shaft 120 and the transmission shaft 102 to rotate, so as to achieve power output, and effectively increase the output of driving force and improve the driving effect. When any one of the first drive member 118 and the second drive member 122 is running, it can also drive the first transition shaft 116, the second transition shaft 120 and the transmission shaft 102 to rotate, ensuring that when one of the first drive member 118 and the second drive member 122 fails and cannot operate, or when the drive device 100 needs to provide a smaller driving force, the drive device 100 can still operate stably.

[0069] Specifically, the first driving member 118 and the second driving member 122 can both be electric motors or hydraulic motors. The output end of the first driving member 118 can be connected to the first transition shaft 116 via a key, and the output end of the second driving member 122 can also be connected to the second transition shaft 120 via a key to achieve transmission of driving force.

[0071] Specifically, the driving device 100 may further include a first sprocket 124 and a second sprocket 126, and the first sprocket 124 and the second sprocket 126 may both rotate when the first driving member 118 and / or the second driving member 122 rotates to output the driving force of the driving device 100. Specifically, the first sprocket 124 is sleeved on the first transition shaft 116 and the transmission shaft 102 at the same time, that is, a part of the inner wall of the first sprocket 124 is opposite to the outer wall of the first transition shaft 116, and the other part is opposite to the outer wall of the transmission shaft 102. In addition, the first sprocket 124 is connected to the first transition shaft 116 and the transmission shaft 102 at the same time through a spline, that is, a spline is provided on the inner wall of the first sprocket 124, and a spline is also provided on the first transition shaft 116 and the transmission shaft 102 at the same time, and a part of the spline on the inner wall of the first sprocket 124 matches with the spline on the first transition shaft 116, and the other part of the spline matches with the spline on the transmission shaft 102. Correspondingly, the second sprocket 126 is sleeved on the second transition shaft 120 and the transmission shaft 102 at the same time, that is, a part of the inner wall of the second sprocket 126 is opposite to the outer wall of the second transition shaft 120, and the other part is opposite to the outer wall of the transmission shaft 102.

A part of the splines on the inner wall of the second sprocket 126 matches with the splines on the second transition shaft 120, and another part of the splines matches with the splines on the transmission shaft 102.

[0072] When the first driving member 118 is in operation, the first transition shaft 116 is driven to rotate, the first transition shaft 116 drives the first sprocket 124 to rotate through the spline, the first sprocket 124 drives the transmission shaft 102 to rotate through the spline, and the transmission shaft 102 drives the second sprocket 126 to rotate through the spline, thereby realizing that the first sprocket 124 and the second sprocket 126 are driven to rotate synchronously only through the operation of the first driving member 118. Correspondingly, when the second driving member 122 is in operation, the second transition shaft 120 is driven to rotate, the second transition shaft 120 drives the second sprocket 126 to rotate through the spline, the second sprocket 126 drives the transmission shaft 102 to rotate through the spline, and the transmission shaft 102 drives the first sprocket 124 to rotate through the spline, thereby realizing that the first sprocket 124 and the second sprocket 126 are driven to rotate synchronously only through the operation of the second driving member 122. Furthermore, by controlling the first driving member 118 and the second driving member 122 to run synchronously, it is also possible to drive the first sprocket 124 and the second sprocket 126 to rotate synchronously, and the driving force can be effectively improved.
