[0028] An adjusting mechanism is movably connected to the outer side of the T-type push rod 17. When the grinding film 6 contacts the inner wall of the tube to be polished under the elastic force of the first spring 33, in order to make the groups of grinding films 6 fit more closely to the inner wall of the tube to be polished, the moving distance of the T-type push rod 17 is finely adjusted by the adjusting mechanism.

After the adjusting mechanism enters the internal threaded hole 26, the adjusting mechanism is locked by the locking mechanism, so that the T-type push rod 17 is limited and fixed, so as to prevent the grinding film 6 from being unable to fit closely to the inner wall of the tube to be polished due to the hydraulic oil flowing back into the storage chamber 11 during the grinding process.

[0029] The outer side of the rotating shaft 1 is movably connected to the supporting plate 20, and the supporting plate 20 is fixedly installed on the upper end of the bottom plate 13.

The transmission mechanism includes a motor 14, and the motor 14 is fixedly installed on the upper end of the bottom plate 13. The motor 14 can select a suitable size and model according to the actual usage. The output end of the motor 14 is fixedly connected to the pulley 15, and the pulley 15 is connected to the belt groove 31 through the belt 16. By turning on the motor 14, the pulley 15 connected to its output end starts to rotate, and the pulley 15 drives the rotating shaft 1 to start rotating through the belt 16. The rotating rotating shaft 1 drives several groups of polishing films 6 to polish the inner wall of the polishing tube.

[0030] Embodiment 2:

[0031] On the basis of Example 1, in order to make several groups of grinding films 6 fit with the inner walls of pipes with different diameters, the grinding mechanism includes several groups of grinding films 6, several groups of grinding films 6 are arranged on the outside of the rotating shaft 1 in a fit with each other, the grinding films 6 are fixedly connected to several groups of adjustment blocks 5 on the side close to the rotating shaft 1, and the several groups of adjustment blocks 5 are movably connected to each other, and the adjustment blocks 5 are movably connected to the T-shaped slider 3 on the side close to the rotating shaft 1, and the T-shaped slider 3 is movably connected to the ball 7 on the side close to the rotating shaft 1, and the T-shaped slider 3 is connected to the ball 7 on the side close to the rotating shaft 1. The arrangement of the ball 7 enables the movement of the T-bar 2 to drive the adjustment block 5 to move. The end of the ball 7 away from the T-sliding block 3 is fixedly connected to the T-bar 2. Under the elastic force of the first spring 33, the T-bar 2 moves upward, and the movement of the T-bar 2 drives the adjustment block 5 to move synchronously. Several groups of adjustment blocks 5 move outward synchronously to contact the inner wall of the tube to be polished. According to the shape of the inner wall of the tube to be polished, several groups of adjustment blocks 5 will bend into corresponding shapes, so that several groups of polishing films 6 fit the inner wall of the tube.

[0032] The end of the T-shaped rod 2 away from the ball 7 is slidably connected to the connection box 8, and the connection box 8 is slidably connected to the connection cavity 9. The connection cavity 9 is opened in the rotating shaft 1. The lower end of the connection box 8 is fixedly connected to the liquid guiding hose 10, and the liquid guiding hose 10 is fixedly installed in the rotating shaft 1. The end of the liquid guiding hose 10 away from the connection box 8 is connected to the storage cavity 11. During the upward movement of the T-shaped rod 2, the hydraulic oil in the storage cavity 11 will enter the connection box 8 through the liquid guiding hose 10. During the movement of the hydraulic oil, the extrusion plate 25 slidably connected to the storage cavity 11 will move inward, and the movement of the extrusion plate 25 drives the T-shaped push rod 17 to move synchronously;

[0033] A first spring 33 is fixedly connected in the connection box 8, and the other end of the first spring 33 is fixedly connected to the T-bar 2. A second spring 12 is fixedly connected in the connection cavity 9, and the other end of the second spring 12 is fixedly connected to the connection box 8. The elastic force of the second spring 12 is greater than the elastic force of the first spring 33. By setting the second spring 12, when a bulge appears on the inner wall of the pipeline, the grinding film 6 at the corresponding position can move inward. When the movement is completed, under the elastic force of the second spring 12, the grinding film 6 returns to its original position, and the T-slider 3 is slidably connected to the T-slot 4, and the T-slot 4 is provided in the adjustment block 5.

[0034] The adjusting mechanism includes a connecting ring 21, an outer thread 19 is provided on the outer side of the connecting ring 21, two groups of guide blocks 27 are fixedly connected to the inner side of the connecting ring 21, the guide blocks 27 are slidably connected to the guide groove 22, the guide groove 22 is provided on the outer side of the T-shaped push rod 17, a plurality of groups of screw grooves 23 are provided in the lower end of the upper guide groove 22, a screw rod 18 is movably connected to the upper end of the connecting ring 21, and the lower end of the screw rod 18 extends into the guide groove 22, and a clamping hole 32 is provided in the upper and lower sides of the connecting ring 21, and the connecting ring 21 is moved to the inner threaded hole 26, and the connecting ring 21 is located in the connecting ring. When the external thread 19 opened on the outer side of 21 moves to the position of the internal thread hole 26, the screw rod 18 is rotated to make its lower end clamped into the screw connection groove 23. After the clamping is completed, the external thread 19 is screwed into the internal thread hole 26 by rotating the connecting ring 21. At this time, as the connecting ring 21 moves, the T-type push rod 17 will be driven to move inward, and the movement of the T-type push rod 17 drives the extrusion plate 25 to move synchronously. The movement of the extrusion plate 25 will make part of the hydraulic oil enter the connection box 8 again, so that the grinding film 6 and the inner wall of the pipe to be polished are more closely attached;

[0035] The locking mechanism includes a cross-shaped clamping rod 28, which is slidably connected in a sliding cavity 29, and the sliding cavity 29 is opened in the rotating shaft 1. A connecting spring 30 is sleeved on the outer side of the cross-shaped clamping rod 28, one end of the connecting spring 30 is fixedly connected to the sliding cavity 29, and the other end is fixedly connected to the cross-shaped clamping rod 28. The upper end of the cross-shaped clamping rod 28 extends into the external environment and is fixedly connected to the knob 24, and the lower end of the cross-shaped clamping rod 28 extends into the internal threaded hole 26. When the connecting ring 21 moves along the internal threaded hole 26, the cross-shaped clamping rod 28 will be pushed to move. When the cross-shaped clamping rod 28 moves to the position of the clamping hole 32, under the elastic force of the connecting spring 30, the lower end of the cross-shaped clamping rod 28 will be clamped into the clamping hole 32, so that the connecting ring 21 cannot move again.

[0036] Working principle: when in use, the base plate 13 is installed together with the moving device of the grinding device, and the tube to be polished is fixed on the grinding device. After the fixing is completed, the rotating shaft 1 is sent into the tube to be polished by the moving device. After the sending is completed, the knob 24 is pulled upward to drive the cross-shaped clamping rod 28 to disengage from the clamping hole 32. After the disengagement is completed, the screw rod 18 is rotated to disengage its lower end from the screw groove 23, and the connecting ring 21 is screwed out of the internal threaded hole 26 and moved to the right side of the T-shaped push rod 17. At this time, the T-shaped push rod 17 is in a movable state;

[0037] Under the elastic force of the first spring 33, the T-bar 2 moves upward, and the movement of the T-bar 2 drives the adjusting block 5 to move synchronously. Several groups of adjusting blocks 5 move outward synchronously to contact the inner wall of the tube to be polished. According to the shape of the inner wall of the tube to be polished, several groups of adjusting blocks 5 will bend into corresponding shapes. During the upward movement of the T-bar 2, the hydraulic oil in the storage chamber 11 will enter the connection box 8 through the liquid guide hose 10. During the movement of the hydraulic oil, the extrusion plate 25 slidably connected to the storage chamber 11 will move inward. The movement of the extrusion plate 25 drives the T-type push rod 17 to move synchronously. When several groups of polishing films 6 are in contact with the inner wall of the tube to be polished, the T-type push rod 17 will no longer move.

[0038] The connecting ring 21 is moved into the internal threaded hole 26. When the external thread 19 provided on the outer side of the connecting ring 21 moves to the position of the internal threaded hole 26, the screw rod 18 is rotated to make its lower end snap into the screw connection groove 23. After the snap connection is completed, the connecting ring 21 is rotated to make the external thread 19 screwed into the internal threaded hole 26. At this time, as the connecting ring 21 moves, the T-type push rod 17 will be driven to move inwards. The movement of the T-type push rod 17 drives the extrusion plate 25 to move synchronously. The movement of the extrusion plate 25 will allow part of the hydraulic oil to enter the connecting box 8 again, so that the polishing film 6 and the inner wall of the pipe to be polished are more closely attached. When the cross-shaped clamping rod 28 moves to the position of the clamping hole 32, under the elastic force of the connecting spring 30, the lower end of the cross-shaped clamping rod 28 will be snapped into the clamping hole 32, so that the connecting ring 21 cannot be moved again.

[0039] The motor 14 is turned on to drive the pulley 15 connected to its output end to start rotating, and the pulley 15 drives the rotating shaft 1 to start rotating through the belt 16. The rotating rotating shaft 1 drives several groups of polishing films 6 to polish the inner wall of the tube to be polished.
