[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 In order to solve the problem that the existing cross-linked polyethylene cable insulation surface is generally polished by manual sandpaper or sanding belt, the polishing depth and the roundness of the insulation layer are difficult to control, sufficient polishing operation experience is required for polishing and finishing, and it is time-consuming and labor-intensive, the following preferred technical solutions are provided:

[0022] A cross-linked polyethylene cable insulation surface polishing tool includes a first connecting frame 1 and a second connecting frame 2. A positioning platform 11 is provided at one end of the second connecting frame 2 away from the first connecting frame 1. A power body 3 is installed on the outer wall of one side of the first connecting frame 1. The outer wall axis of the first connecting frame 1 is connected to a movable frame 4. The output end of the power body 3 is rotatably connected to a driving wheel 5. The outer wall of the movable frame 4 is rotatably connected to a first transmission wheel 6. The outer wall of the second connecting frame 2 is rotatably connected to a second transmission wheel 7. The driving wheel 5, the first transmission wheel 6 and the second transmission wheel 7 are transmission-connected to a polishing belt 8. The outer wall of the second connecting frame 2 is fixedly connected to an outer rod body 9. The inner wall of the outer rod body 9 is slidably connected to an inner rod body 10.

[0023] One end of the inner rod body 10 away from the outer rod body 9 is connected to the second connecting frame 2, and the outer wall axis of the first connecting frame 1 away from the outer rod body 9 is connected to the electric push rod 12, and the output end of the electric push rod 12 is connected to the movable frame 4 axis.

[0024] A fixed channel 13 is provided on the outer wall of the inner rod body 10, and a reinforcement assembly 14 is provided on the outer wall of the outer rod body 9. The reinforcement assembly 14 includes a control block 141 overlapped on the outer wall of the outer rod body 9, and one end of the control block 141 is fixedly connected to a middle connecting rod 142. The middle connecting rod 142 passes through the outer wall of the outer rod body 9, and the end of the middle connecting rod 142 away from the control block 141 is fixedly connected to a reinforcement block 143. The reinforcement block 143 is buckled with the inner wall of the fixed channel 13, and an elastic element 144 is fixedly connected to the opening of the outer wall of the outer rod body 9. One end of the elastic element 144 is fixedly connected to the control block 141. When the control block 141 is attached to the outer wall of the outer rod body 9, the elastic element 144 is in a relaxed state.

[0025] After the paving is completed, the driving wheel 5 is automatically turned to the driving wheel 5, and the driving wheel 5, the first transmission wheel 6 and the second transmission wheel 7 are turned to the driving wheel 5. The second transmission wheel 6 and the second transmission wheel 7 can be turned to the second driving wheel 8. The second transmission wheel 6 can be turned to the second driving wheel 8, so that the paving wheel 5 can be turned to the second driving wheel 8. The second transmission wheel 6 can be turned to the second driving wheel 8, so that the paving wheel 5 can be turned to the second driving wheel 8. The second transmission wheel 6 can be turned to the second driving wheel 8, so that the paving wheel 5 can be turned to the second driving wheel 8.

[0026] When driving the inner rod body 10 to move along the inner wall of the outer rod body 9, it is necessary to first pull the control block 141 outward. The control block 141 will drive the middle connecting rod 142 to move outward, so that the middle connecting rod 142 drives the reinforcing block 143 to separate from the inner wall of the fixed channel 13, and the elastic element 144 is also tightened. At this time, the inner rod body 10 can move along the inner wall of the outer rod body 9. After the movement is completed, the control block 141 is released. At this time, the reinforcing block 143 will be driven by the elastic element 144 to snap into the inner wall of the fixed channel 13. At this time, the inner rod body 10 cannot move along the inner wall of the outer rod body 9, which can avoid the phenomenon of accidental touch.
