[0022] As Figure 1 , Figure 2 and Figure 3 indicated, a steel pipe burr polishing device, comprising: device support 1, the lifting assembly 2 located on both sides of the device support 1 through the sliding slot formed on the device support 1 and the device support 1 sliding connection, and the polishing assembly 3 also with the device support 1 through the sliding slot sliding connection and located between the two lifting assemblies 2;Specifically, the lifting assembly 2 includes: hydraulic pump 21, lifting rod 23 arranged at the output end of the hydraulic pump 21, hand lever 22 for applying mechanical kinetic energy to the hydraulic pump 21, and first support 24 fixedly connected at the end of lifting rod 23 away from the hydraulic pump 21;Specifically, the polishing assembly 3 includes: rotary motor 31, polishing piece 32 arranged at the output end of the rotary motor 31, and fixing piece arranged at the end of rotary motor 31 away from the polishing piece 32;The synchronous rod 221 matched with the inner diameter of the connecting ring is detachably connected between the hand levers 22 of the two lifting assemblies 2 through the connecting ring, and the synchronous rod 221 is used for ensuring that the same force is applied to the two lifting assemblies 2 at the same time.

[0023] Based on the above setting, the first support 24 can be used to extend into the hollow of the steel pipe from both sides, then the synchronous rod 221 is used to apply force to the hand lever 22 in the two lifting assemblies 2 at the same time, the liquid pressure generated by the hydraulic pump 21 is used to lift the lifting rod 23, the first support 24 fixedly welded with the lifting rod 23 is used to lift the steel pipe away from the ground, then the grinding assembly 3 connected with the device support 1 is used to grind the burrs on the outer side of the steel pipe, and the lifting assembly 2 is used to suspend the steel pipe in the air, which is convenient for the rotation of the steel pipe during grinding, and the operator can operate more labor-saving.

[0024] Further, the first support 24 comprises a first connecting rod 241 fixedly welded with the lifting rod 23, a first support wheel 242 rotationally connected with the first connecting rod 241, and a second support connected with the first connecting rod 241 through threads and capable of adjusting the connection position; specifically, the second support comprises a threaded rod 243 connected with the first connecting rod 241 through threads, a second connecting rod 244 rotationally connected with the threaded rod 243, and a second support wheel 245 rotationally connected with the connecting rod, the diameter of the first support wheel 242 is greater than the diameter of the first connecting rod 241, the diameter of the second support wheel 245 is greater than the diameter of the second connecting rod 244, and rubber pads are bonded on the outer sides of the first support wheel 242 and the second support wheel 245.

[0025] Based on the above setting, after the first supporting wheel 242 and the second supporting wheel 245 are simultaneously inserted into the hollow part of the steel pipe, the distance between the second supporting wheel 245 and the first supporting wheel 242 can be changed by rotating the threaded rod 243, so that the first supporting wheel 242 abuts against the upper part of the hollow part of the steel pipe, and the second supporting wheel 245 abuts against the lower part of the hollow part of the steel pipe, thereby keeping the steel pipe stable during lifting; through the setting of the threaded rod 243, the distance between the first supporting wheel 242 and the second supporting wheel 245 can be adjusted arbitrarily, thereby adapting to steel pipes of different diameters and increasing the application range of the utility model; the setting that the first supporting wheel 242 and the second supporting wheel 245 are respectively rotationally connected with the first connecting rod 241 and the second connecting rod 244 can realize that the first supporting wheel 242 and the second supporting wheel 245 rotate simultaneously with the rotation of the steel pipe, thereby reducing the abrasion of the lifting assembly 2 when the steel pipe rotates; the setting that the second connecting rod 244 is rotationally connected with the threaded rod 243 ensures that after the threaded rod 243 is rotated arbitrarily, the second supporting wheel 245 can still face the steel pipe by rotating the second connecting rod 244, so that the central axes of the first supporting wheel 242 and the second supporting wheel 245 are parallel to each other, thereby ensuring the strong and stable supporting effect on the steel pipe and the rationality of the device structure; the design of the rubber pad increases the friction force between the first supporting wheel 242 and the second supporting wheel 245 and the steel pipe, which is beneficial to improving the stability of the lifting of the steel pipe.
