[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Through the design of the grip rod, the auxiliary pushing mechanism, the pipe inner wall polishing mechanism and the motor, when polishing the inner wall of the pipe, the staff can hold the outer surface of the grip rod and then push the pipe inner wall polishing mechanism into the pipe, and at the same time, the auxiliary pushing mechanism at the rear end of the pipe inner wall polishing mechanism will be limited by the space of the pipe, so that it can be adapted to the diameter of the pipe.

Then the staff only needs to hold the grip to make the polishing sheet rotate and polish in the pipeline, and apply a pushing force, which can be pushed by the support of the rollers. The set polishing sheet can be pushed by the gas to increase the diameter, so that it can be adapted to pipelines of different diameters, thereby increasing the applicability of this device.

[0027] Through the design of the grip 1, the auxiliary pushing mechanism 2, the pipe inner wall polishing mechanism 3 and the motor 102, when polishing the inner wall of the pipe, the staff can hold the outer surface of the grip 1 and then push the pipe inner wall polishing mechanism 3 into the pipe, and at the same time, the auxiliary pushing mechanism 2 at the rear end of the pipe inner wall polishing mechanism 3 will be limited by the space of the pipe, so that it can be adapted to the diameter of the pipe. The auxiliary pushing mechanism 2 can limit the pipe inner wall polishing mechanism 3 at the center of the pipe. Then the staff can push the grip 1 and start the motor 102 to drive the pipe inner wall polishing mechanism 3 at the center of the pipe to perform a rotational polishing and grinding operation on the inside of the pipe. The device is small in size and can be carried and used by the staff at any time, eliminating the need for the staff to lift and place the pipe, allowing the staff to directly walk to the placement position of the pipe and insert it for use, thereby improving the polishing efficiency of the pipe.

[0028] like Figure 4 As shown, the auxiliary pushing mechanism 2 includes a connecting column 201, which is fixedly installed between the mounting plate 101 and the docking plate 103. A first connecting rod 204 is rotatably installed on the outer surface of the connecting column 201. A slide groove 202 is opened at one end of the connecting column 201. A push plate 207 is slidably installed in the slide groove 202. A second connecting rod 205 is rotatably installed on the outer surface of the push plate 207. A roller 206 is rotatably installed between the other ends of the first connecting rod 204 and the second connecting rod 205.

[0030] The design of the connecting column 201, the roller 206, the sliding column 208, the spring 203, the first connecting rod 204 and the second connecting rod 205 is such that after the staff pushes the pipeline inner wall polishing mechanism 3 into the pipeline, if the second connecting rod 205 with the rear end tilted is larger than the diameter of the pipeline, it will be pressed by the pipe mouth, and the second connecting rod 205 will drive the push plate 207 to slide in the slide groove 202 and touch one end of the spring 203 at the same time, and at the same time, the second connecting rod 205 will also drive the roller 206 to pull the first connecting rod 204 to rotate together, and the spring 203 will apply a push to the second connecting rod 205, which can ensure that the second connecting rod 205 can push the roller 206 to fully touch the inner wall of the pipeline for rolling, and through the three groups of rollers 206 rolling at three angles, an auxiliary support effect can be applied to the grip 1, and the pipeline inner wall polishing mechanism 3 at the front end can be supported in the air at the center of the pipeline for grinding and polishing operations;

[0031] Furthermore, the push plate 207 can slide in the slide groove 202 and pull the second connecting rod 205 and the first connecting rod 204 to slide downward, thereby reducing the diameter of the roller 206 that expands outward, so that it can match pipes of various diameters for supporting operations.

[0032] like Figure 5 As shown, the pipeline inner wall polishing mechanism 3 includes an air pump 301, which is fixedly installed in the sleeve 104 and fixedly installed on one end of the output shaft of the motor 102. A ventilation pipe 304 is fixedly installed at one end of the air port of the air pump 301, and a connecting plate 302 is fixedly installed on the outer surface of the ventilation pipe 304.

[0034] The polishing sheet 306 is inflated into the air passage 303 through the air pump 301 to push the piston rod 305, so that the polishing sheet 306 expands outward.

[0035] Through the design of the air pump 301, the connecting plate 302, the airway 303, the vent pipe 304, the piston rod 305 and the polishing sheet 306, when the three sets of rollers 206 are supported in the pipeline, the staff can start the air pump 301 to inflate the vent pipe 304, and the vent pipe 304 can fill the gas into the airway 303, so that the gas can push the piston rod 305 of the airway 303 to slide outward, so that the piston rod 305 can drive the polishing sheet 306 to expand outward and touch the inner wall of the pipeline, and then the motor 102 can be started to drive the air pump 301 to inflate the vent pipe 304, and the vent pipe 304 can inflate the gas into the airway 303. The pump 301 rotates in the sleeve 104, and the sleeve 104 drives the connecting disk 302 and the polishing sheet 306 to rotate at one end of the docking plate 103 through the vent pipe 304. Then the staff only needs to hold the handle 1 tightly to make the polishing sheet 306 rotate and polish in the pipeline, and apply a pushing force. The polishing sheet 306 can be pushed by the support of the roller 206.

[0036] According to the above technical scheme, the working steps of this scheme are summarized and sorted out: when polishing the inner wall of the pipe, the staff can hold the outer surface of the grip 1 and then push the grip 1 into the pipe. During the pushing process, if the inclined second connecting rod 205 is larger than the diameter of the pipe, it will be pressed by the pipe mouth, and the second connecting rod 205 will drive the push plate 207 to slide in the slide groove 202 and touch one end of the spring 203 at the same time. At the same time, the second connecting rod 205 will also drive the roller 206 to pull the first connecting rod 204 to rotate together, and the spring 203 will exert a push on the second connecting rod 205, which can ensure that the second connecting rod 205 can push the roller 206 to fully touch the inner wall of the pipe for rolling, and through the three groups of rollers 206 rolling at three angles, an auxiliary support effect can be applied to the grip 1, which can The polishing sheet 306 at the front end can be suspended in the center of the pipeline, and then the air pump 301 can be started to inflate the ventilation pipe 304, and the ventilation pipe 304 can fill the gas into the airway 303, so that the gas can push the piston column 305 of the airway 303 to slide outward, so that the piston column 305 can drive the polishing sheet 306 to expand outward and touch the inner wall of the pipeline, and then the motor 102 can be started to drive the air pump 301 to rotate in the sleeve 104, and the sleeve 104 will drive the connecting disk 302 and the polishing sheet 306 to rotate at one end of the docking plate 103 through the ventilation pipe 304, and then the staff only needs to hold the grip 1 tightly to make the polishing sheet 306 rotate and polish in the pipeline, and apply a pushing force, so that the polishing sheet 306 can be pushed by the support of the roller 206, and the purpose of polishing the inner wall of the pipeline is completed.

Moreover, the device is small in size and can be carried and used by staff at any time, eliminating the need for staff to lift and place the pipe, allowing staff to directly walk to the placement of the pipe and insert it for use, thereby improving the polishing efficiency of the pipe.
