[0023] like Figure 7 and Figure 8As shown, in one embodiment: the traction structure 8 includes a rotating seat 808 fixed to one side of the bottom end of the mounting plate 603, a first pneumatic telescopic rod 801 rotatably connected to the bottom end of the rotating seat 808, a slide seat 802 fixed to the outside of the first pneumatic telescopic rod 801, a slide groove 807 installed at the bottom end of the mounting plate 603 and slidably connected to the slide seat 802, a rotating seat 806 installed at the telescopic end of the first pneumatic telescopic rod 801, a jacket 803 fixed to one side of the rotating seat 806, a second screw 805 rotatably connected to the inside of the top end of the jacket 803, and a second clamping plate 804 rotatably connected to the bottom end of the second screw 805, and the cleaning structure 18 includes a rotating seat 808 installed at the fixed A first fixed frame 1803 on one side of the positioning arm 601, a second fixed frame 1804 installed on one side of the top end of the cover shell 607, a wire brush 1801 rotatably connected between the second fixed frame 1804 and the first fixed frame 1803, and a cleaning motor 180 installed on one side of the first fixed frame 1803 and with an output shaft connected to the wire brush 1801; by pulling the jacket 803 to move to the outside of the cutting steel plate, and using the jacket 803 and the second clamping plate 804 to clamp the steel plate, the positioning structure 6 positions and guides the steel structure, and then the first pneumatic telescopic rod 801 is started to retract, and the device is quickly pulled toward the steel structure, reducing the time for manual handling and positioning.

[0024] like Figure 3 and Figure 4 As shown, in one embodiment: an outer wall of the screw rod 610 is provided with an external thread, and the interior of the moving block 608 is provided with an internal thread that cooperates with the external thread. Through the engagement of the internal and external threads, the screw rod 610 pushes the moving block 608 to move left and right during the rotation process.

[0025] like Figure 5 and Figure 6 As shown, in one embodiment: when the flip frame 710 contacts the baffle 709, the torsion spring 707 is in a natural state; the rotational force of the fixed ring 706 is transmitted by the torsion spring 707, so that after the connecting frame 708 and the flip frame 710 stop rotating, the fixed ring 706 and the transmission shaft 702 can continue to rotate and move a distance by pushing the torsion spring 707 to twist.

[0026] like Figure 5 and Figure 6 As shown, in one embodiment: the fixing ring 706 is connected to the connecting frame 708 through the torsion spring 707, and a rotating structure is formed between the connecting frame 708 and the transmission shaft 702.

[0027] like Figure 7As shown, in one embodiment: the second screw 805 extends to the interior of the jacket 803 and is connected to the second clamping plate 804, and a sliding structure is formed between the second clamping plate 804 and the jacket 803; by rotating the second screw 805, the second screw 805 pushes the thread to push the second clamping plate 804 to move downward, and at the same time, the second clamping plate 804 slides inside the jacket 803, making it difficult for it to rotate with the second screw 805.

[0028] Specifically, when the steel structure cutting equipment is in use: the pushing device is moved to the processing area, and the sliding sleeve 4 is driven to move along the outer side of the slide rail 2 by activating the second pneumatic telescopic rod 12, and the height of the positioning seat 16 is adjusted to ensure that the groove part of the positioning seat 16 is accurately aligned with the steel structure. The universal wheel 17 is used to move the device so that the steel structure is placed on the inner side of the positioning structure 6, and the traction structure 8 is connected to the steel structure. The positioning structure 6 is used to position the steel structure so that it is parallel to the device. Then, the traction structure 8 is used to shorten the distance between the steel structure and the device until the steel structure contacts the positioning seat 16. At the same time, the fixing structure 7 and the positioning seat 16 work together to clamp and fix the position of the steel structure. After that, the height of the laser cutter 14 is adjusted in the vertical direction by starting the screw slide 11 so that it contacts the steel structure. Then, according to the preset parameters, the movement of the transverse belt slide 13 and the longitudinal belt slide 9 is accurately controlled so that the laser cutting machine 14 cuts according to the predetermined pattern. When the cutting path is completed, the operation of the laser cutter 14 is stopped. The positioning roller 602 is brought into contact with one side of the steel structure by the moving device, and then the driving motor 606 is started to rotate, driving the screw rod 610 to rotate, and then the moving block 608 drives the moving arm 605 to move left and right, and adjusts the position of the guide roller 604, so that the guide roller 604 contacts the steel structure. When the position where the device is placed is offset, only one set of guide rollers 604 of the two sets of guide rollers 604 contacts the steel structure, and the driving motor 606 is started to rotate, so that the guide rollers 604 apply thrust to the steel structure, and the thrust reacts to the device, so that the fixed structure 7 drives the frame 1 to slide around the positioning roller 602, and adjusts the angle and position of the frame 1 so that the two sets of guide rollers 604 contact the device, and the device is parallel to the steel structure. At the same time, the positioning rollers 602 and the guide rollers 604 limit the direction of movement of the device, and the traction structure 8 is contracted to pull the device so that the positioning seat 16 contacts the steel structure to limit the position of the steel structure; The first pneumatic telescopic rod 801 is extended to its maximum length, and then the first pneumatic telescopic rod 801 is pulled to rotate around the rotating seat 808, so that the jacket 803 is located on the outside of the cut steel plate, and the second screw rod 805 is rotated to push the second clamping plate 804 downward, so that the jacket 803 and the second clamping plate 804 clamp the steel plate, so that the positioning structure 6 can position and guide the steel structure and limit the direction of movement of the steel structure, and the first pneumatic telescopic rod 801 is started to contract, and the pulling device moves toward the steel structure, so that the positioning seat 16 contacts the steel structure, and the slide seat 802 slides inside the slide groove 807 to guide the movement of the first pneumatic telescopic rod 801, and the position of the slide seat 802 is limited; During the process of pulling the steel structure, the steel structure moves at the bottom of the wire brush 1801. By starting the cleaning motor 1802 to drive the wire brush 1801 to rotate, the wire brush 1801 cleans the surface of the moving steel structure, effectively removing foreign matter and debris on the surface of the steel structure. The position of the wire brush 1801 is fixed by the first fixing frame 1803 and the second fixing frame 1804. The threads between the first fixing frame 1803 and the positioning arm 601 and between the second fixing frame 1804 and the cover 607 are disassembled, and the cleaning structure 1801 can be disassembled. The first clamping plate 712 is rotated according to the thickness of the steel plate of the steel structure before use, so that the first clamping plate 712 is turned over and just clamped with the positioning seat 16 to fix the position of the steel structure. When the traction structure 8 pulls the device to move toward the steel structure, the steel structure pushes the pressing plate 701 to move backward, and the pressing plate 701 drives the toothed plate 704 to move backward, and the teeth of the toothed plate 704 are used to push the gear 705 to drive the transmission shaft 702 to rotate, and then the transmission shaft 702 drives the connecting frame 708 to rotate through the fixing ring 706 and the torsion spring 707, and the flip frame 710 is flipped over, so that the first clamping plate 712 contacts the steel structure and applies an upward thrust to the steel structure, so that the first clamping plate 712 and the positioning seat 16 clamp the position of the steel structure, so that the steel structure and the device are not easy to separate and shake during the processing. The movement of the toothed plate 704 is guided by the guide sleeve 703, so that the toothed plate 704 and the pressing plate 701 can only move in a straight line.
