[0013] Compared with the prior art, the advantages and positive effects of the utility model are:
[0014] 1. According to the utility model, when it is necessary to fix the steel pipe, the steel pipe is first placed on the surface of the two electric push rods, and the two electric push rods are operated by the control terminal. The two electric push rods move to push the steel pipe. When the steel pipe is level with the two fixed components, the steel pipe is pushed so that one of the fixed components is completely located inside the steel pipe. At this time, the first motor is operated by the control terminal. The operation of the first motor drives the first threaded rod to rotate. The rotation of the first threaded rod drives the movable plate to move on the surface of the cross bar. The movement of the movable plate on the surface of the cross bar drives another fixed component to move. When the two fixed components are completely located inside the steel pipe, the operation of the first motor is stopped and the two T-shaped slides are pulled.

The rotation of the two rotating rods drives multiple transmission gears to rotate. The rotation of the multiple transmission gears drives and engages with multiple racks, thereby causing multiple T-shaped slides to move. The movement of multiple T-shaped slides drives multiple arc-shaped fixed plates to move. When the multiple arc-shaped fixed plates can firmly support the inner wall of the column steel pipe, the two T-shaped slides are released at this time, and the rebound force of the two springs is used to make the two limit rods reinsert into the corresponding limit blocks, so as to limit the rotation of the rotating plate, and then complete the fixation of the inner wall of the steel pipe. Through the cooperation of the above structure, multiple arc-shaped fixed plates can support and fix the inner wall of the steel pipe, which is convenient for comprehensive grinding of the surface of the steel pipe, avoids the need to readjust the fixed position of the steel pipe, and greatly improves the efficiency of grinding the surface of the steel pipe.
[0015] 2. In the utility model, when it is necessary to grind the surface of the steel pipe in an all-round manner, firstly, two cylinders are operated through the control terminal, and the operation of the two cylinders drives the two cross blocks to move inside the two cross grooves, and the movement of the two cross blocks inside the two cross grooves drives the movement of multiple support plates, and the movement of multiple support plates drives the movement of two grinding rollers. When the two grinding rollers move to a suitable distance, the operation of the two cylinders is stopped through the control terminal, and two third motors and two fourth motors are operated. The operation of the two third motors drives the two second threaded rods to rotate, and the rotation of the two second threaded rods drives the two L-shaped plates to move, and the movement of the two L-shaped plates drives the two grinding rollers to move. At the same time, the operation of the fourth motor drives the belt roller to rotate, and each of the multiple belt rollers is a group of two, and a transmission belt is connected between them, so that The two grinding rollers rotate, and the two third motors are run forward and backward to make the two grinding rollers grind the surface of the steel pipe.

The operation of the two cylinders 907 drives the two cross blocks 906 to move inside the two cross grooves 905. The movement of the two cross blocks 906 inside the two cross grooves 905 drives the multiple support plates 908 to move. The movement of the multiple support plates 908 drives the two grinding rollers 909 to move. When the two grinding rollers 909 move to a suitable distance, the operation of the two cylinders 907 is stopped through the control terminal 3 and the two third motors 903 and the two fourth motors 910 are operated. The operation of the two third motors 903 drives the two second threaded rods 902 to rotate. The rotation of the two second threaded rods 902 drives the two L-shaped plates 904 to move.

The two rotating shafts 703 drive the two gears 705 to rotate. The two gears 705 rotate and mesh with the two gear rings 701, so that the two rotating columns 7 rotate. The rotation of the two rotating columns 7 drives the two fixed components 8 to rotate. The rotation of the two fixed components 8 drives the steel pipe to rotate, and then the surface of the steel pipe is fully grinded. Through the cooperation of the above structure, the distance between the two grinding rollers 909 can be adjusted according to the diameter of the steel pipe, and can move around the steel pipe at the same time. The two second motors 704 drive the steel pipe to rotate, so that the two grinding rollers 909 can fully grind the surface of the steel pipe. ;
