[0031] Embodiment 1

[0032] See also Figure 1-Figure 4 As shown in the figure, a steel pipe rod joint device includes a support seat 100, a lower clamping seat 200 is fixedly connected inside the support seat 100, a threaded rod 300 is connected to the support seat 100 by threading, and the bottom of the threaded rod 300 is rotatably connected to the upper clamping seat 400, and a steel pipe edge cleaning device 500 is installed inside the support seat 100. The steel pipe is placed on the lower clamping seat 200, and the upper clamping seat 400 rotatably connected to the threaded rod 300 is driven to move downward by rotating the threaded rod 300, so as to cooperate with the lower clamping seat 200 to clamp the steel pipe;

[0033] An adjustment assembly 600 is arranged inside the upper clamping seat 400. The adjustment assembly 600 includes a torsion spring rod 601, which is located at the top of the threaded rod 300. The torsion spring rod 601 is in a rotational connection with the threaded rod 300. A manipulation handle 602 is fixedly connected to one side of the torsion spring rod 601, and a clamping plate 603 is fixedly connected to the other side of the torsion spring rod 601. When the diameter of the steel pipe is small, the manipulation handle 602 is squeezed to cooperate with the torsion spring rod 601 fixedly connected to the manipulation handle 602, and the torsion spring rod 601 and the threaded rod 300 are in a rotational connection state, so that the manipulation handle 602 drives the torsion spring rod 601 to rotate, so that the torsion spring rod 601 drives the clamping plate 603 fixedly connected thereto to rotate sideways. The threaded rod 300 is internally slidably connected to a push rod 604, and a fastening groove 605 is provided on the outer side of the push rod 604. The fastening groove 605 is located on the inner side of the clamping plate 603, and the shape of the fastening groove 605 is adapted to the clamping plate 603. A through groove 606 is provided inside the upper clamping seat 400, and a small clamping seat 607 is rotatably connected to the bottom of the push rod 604. When the clamping plate 603 rotates sideways and away from the fastening groove 605 on the push rod 604, the push rod 604 loses its restriction and is pushed downward, so that the push rod 604 drives the small clamping seat 607 rotatably connected to it to move downward and move out from the through groove 606 of the upper clamping seat 400 to clamp the steel pipe with a smaller diameter; after the clamping is completed, it is then released and the handle 602 is operated, so that the torsion spring rod 601 immediately loses its restriction and resets under its own action, thereby clamping the push rod 604, so that the device can also stably clamp the steel pipe with a smaller diameter, thereby improving the scope of use of the device.

[0034] When in use, place the steel pipe on the lower clamping seat 200, and by rotating the threaded rod 300, drive the upper clamping seat 400 connected with the threaded rod 300 to move downward, and cooperate with the lower clamping seat 200 to clamp the steel pipe. When the diameter of the steel pipe is small, by squeezing the operating handle 602, cooperate with the torsion spring rod 601 fixedly connected to the operating handle 602, and the torsion spring rod 601 and the threaded rod 300 are in a rotationally connected state, so that the operating handle 602 drives the torsion spring rod 601 to rotate, so that the torsion spring rod 601 is brought The clamping plate 603 fixedly connected to it is moved to rotate sideways and away from the fastening groove 605 on the push rod 604. At this time, the push rod 604 loses its restriction and is pushed downward, so that the push rod 604 drives the small clamping seat 607 rotatably connected to it to move downward and move out from the through groove 606 of the upper clamping seat 400 to clamp the steel pipe with a smaller diameter; after the clamping is completed, it is then released and the handle 602 is operated, so that the torsion spring rod 601 immediately loses its restriction and resets under its own action, thereby clamping the push rod 604.

[0035] To prevent the brush head 707 from vibrating and causing the steel tube to dislocate, please refer to Figure 1-Figure 5As shown in the figure, a shock absorbing assembly 700 is arranged inside the steel pipe edge cleaning device 500, and the shock absorbing assembly 700 includes an electric telescopic rod 701, and a shock absorbing bin 702 is installed at the bottom of the electric telescopic rod 701. The shock absorbing bin 702 includes an oil chamber 703 and a spare chamber 704. The oil chamber 703 is filled with matching oil, while the spare chamber 704 is not provided with oil. The bottom of the shock absorbing bin 702 is slidably connected with a connecting rod 706, and the top of the connecting rod 706 is fixedly connected with a spring 705, one end of the spring 705 is connected to the connecting rod 706, and the other end of the spring 705 is connected to the shock absorbing bin 702, the bottom of the connecting rod 706 is equipped with a brush head 707, and the outer side of the spare chamber 704 is fixedly connected with an elastic air bag 708. When the brush head 707 is rotating, if it tends to vibrate due to squeezing the steel pipe, the connecting rod 706 squeezes the spring 705 fixedly connected to it and moves upward, and the connecting rod 706 immediately squeezes the oil in the oil chamber 703 into the empty chamber 704 on the outside, and the air in the empty chamber 704 is immediately pushed into the elastic airbag 708 fixedly connected to it. Due to the damping nature between the oil and the warehouse body, the vibration amplitude formed by the connecting rod 706 and the brush head 707 is reduced, preventing the vibrating brush head 707 from affecting the seam closing effect. At the same time, after completing a shock absorbing operation, the connecting rod 706 immediately resets the brush head 707 under the action of the spring 705 to facilitate the subsequent use of the device.

[0036] During use, when the brush head 707 is rotating, if it tends to vibrate due to the squeezing of the steel pipe, the connecting rod 706 will squeeze the spring 705 fixedly connected to it and move upward. The connecting rod 706 will then squeeze the oil in the oil chamber 703 into the empty chamber 704 on the outside, and the air in the empty chamber 704 will be pushed into the elastic airbag 708 fixedly connected to it. Due to the damping property between the oil and the warehouse body, the vibration amplitude formed by the connecting rod 706 and the brush head 707 is reduced. At the same time, after completing a shock absorbing operation, the connecting rod 706 will immediately reset the brush head 707 under the action of the spring 705.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
