[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In this application, the second hydraulic cylinders on both sides are started. The two second hydraulic cylinders drive the two guide plates to move, thereby driving the two guide rods to move. When the guide rods move, they drive the two second connecting plates to move, so as to drive the swing rod to deflect, and control the multiple support wheels to be parallel during movement, which is convenient for fitting with the inner walls of the grooves on both sides of the H-shaped steel. During movement, the multiple traveling wheels will be attached to the outer surface of the H-shaped steel, so as to attach the fixing frame to the outside of the H-shaped steel. The traveling wheels are driven to rotate by the micro motor installed inside the mounting frame, and then the movement of the fixing frame on the surface of the H-shaped steel is controlled, which is convenient for the welding machine to weld the steel. The movement is convenient, the stability is high, and the working efficiency of welding is improved.

[0017] 2. In this application, when the third guide rail moves up and down, due to the self-weight of the parts above the third guide rail, when the third guide rail rises and falls, the third guide rail drives the articulated plate to rise and fall, so that the articulated plate drives the baffle and the sleeve to rise and fall, so that the sleeve drives the piston shell to slide inside the piston cylinder. Because the piston cylinder is filled with buffer liquid, the buffer liquid flows through the multiple through holes inside the piston shell to form a damping effect. At the same time, when the baffle moves relative to the piston cylinder, the second spring is squeezed or stretched, so as to buffer the third guide rail during the lifting process, so as to improve the stability of the third guide rail driving the welding machine during lifting.

[0018] 3. In this application, the guide head deflects when moving along with the spiral groove, so as to drive the moving sleeve to deflect. When the moving sleeve deflects, it limits the position of the limiting groove through the limiting plate, driving the support shaft to rotate. When the support shaft rotates, it drives the fixed rod and the liquid blocking plate to rotate. When the liquid blocking plate rotates inside the piston shell, the opening size of the through hole is controlled by the relative angle between the liquid blocking plate and the piston shell. When the opening of the through hole is smaller, when the buffer liquid flows through the through hole, the resistance is greater, and vice versa, the resistance is smaller, so as to control the size of the damping effect when the piston shell moves, thereby adjusting the buffering effect on the third guide rail. When the third guide rail only rises and falls, the opening of the through hole is increased to reduce the resistance, which is convenient for rapid movement. When moving during welding, the opening of the through hole is reduced to increase the resistance, thereby improving the damping effect and enhancing the stability of the third guide rail during movement, improving the welding quality of the welding machine, which is beneficial to adjusting the damping effect according to different application scenarios, adapting to different working scenarios, and being convenient for use.

[0040] Both ends of the rear side of the fixing frame 1 are fixedly connected with mounting frames 56. Both ends of the two sides of the two mounting frames 56 are rotatably connected with traveling wheels 57. Both ends of the inside of the mounting frame 56 are provided with micro motors. The plurality of traveling wheels 57 are respectively fixedly connected with the output ends of the plurality of micro motors.

One side of the inside of the fixing frame 1 is fixedly connected with a fourth motor 40. The output end of the fourth motor 40 is fixedly connected with a gear 41. The two toothed plates 39 are respectively meshed with the upper and lower sides of the fourth motor 40. By starting the fourth motor 40 to drive the gear 41 to rotate, the two toothed plates 39 are driven to move in opposite directions. One end of the moving frame 38 is fixedly connected with a fourth motor 40. One side of the fourth motor 40 is fixedly connected with a side plate 42. Both ends of one side of the side plate 42 are fixedly connected with support plates 43. Two swing rods 44 are hinged to one side of the support plates 43.

Both ends of the third spring 52 are respectively fixedly connected with the side plate 42 and the contact plate 50, so that the contact plate 50 is first attached to the steel structure.

[0041] When this solution is in use, place the fixing frame 1 on one side of the H-shaped steel. Start the fourth motor 40 to drive the gear 41 to rotate. Then, the gear 41 drives the two toothed plates 39 to move relatively. When the two toothed plates 39 move, they drive the two moving frames 38 to move relatively, causing the two moving frames 38 to drive the two side plates 42 to move, and the two side plates 42 to drive the two side support plates 43 to move relatively, so that multiple support wheels 45 are respectively located on both sides of the H-shaped steel. Then, reverse-start the fourth motor 40 to move the side plates 42 on both sides towards the middle, and move the support wheels 45 on both sides into the grooves of the H-shaped steel. At the same time, when the two contact plates 50 move relatively, they first fit with the steel. After the fitting is completed, start the two second hydraulic cylinders 46 on both sides, so that the two second hydraulic cylinders 46 drive the two guide plates 47 to move, thereby driving the two guide rods 49 to move. When the guide rods 49 move, they drive the two second connecting plates 48 to move, so as to drive the swing rod 44 to deflect, controlling the multiple support wheels 45 to be parallel during movement, facilitating fitting with the inner walls of the grooves on both sides of the H-shaped steel. During movement, multiple walking wheels 57 will fit with the outer surface of the H-shaped steel, thereby fitting the fixing frame 1 on the outside of the H-shaped steel. Drive the walking wheels 57 to rotate through the micro-motor installed inside the mounting frame 56, and then control the fixing frame 1 to move on the surface of the H-shaped steel, facilitating the welding machine 7 to weld the steel. The movement is convenient, the stability is high, and the welding work efficiency is improved.

[0042] Start the first motor 35 to drive the first self-locking lead screw 30 to rotate, so that the first mounting block 31 drives the support rail 8 to move. When the support rail 8 moves, it drives the third guide rail 5 and the moving block 6 to move, thereby driving the welding machine 7 to move, which is beneficial to adjusting the horizontal position of the welding machine 7. Start the second motor 36 to drive the second self-locking lead screw 32 to rotate, so that the second self-locking lead screw 32 drives the second mounting block 33 to move. Then, the second mounting block 33 drives the third guide rail 5 and the third guide rail 5 to move up and down to adjust the height of the welding machine 7. Start the third motor 37 to drive the third self-locking lead screw 34 to rotate, and then drive the moving block 6 and the welding machine 7 to move back and forth, facilitating the adjustment of the distance between the welding machine 7 and the steel structure for welding.

[0043] When the third guide rail 5 moves up and down, due to the self-weight of the parts above the third guide rail 5, when the third guide rail 5 ascends and descends, the third guide rail 5 drives the hinge plate 29 to ascend and descend, thereby causing the hinge plate 29 to drive the baffle 13 and the sleeve 12 to ascend and descend, and further causing the sleeve 12 to drive the piston housing 11 to slide inside the piston cylinder 10. Since the piston cylinder 10 is filled with buffer liquid, the buffer liquid flows inside the multiple through holes 25 inside the piston housing 11, forming a damping effect. At the same time, in cooperation with the baffle 13 squeezing or stretching the second spring 28 during the relative movement with the piston cylinder 10, the third guide rail 5 is buffered during the ascending and descending process, so as to improve the stability of the third guide rail 5 driving the welding machine 7 during the ascending and descending process.

[0044] By starting the first hydraulic cylinder 15, the first hydraulic cylinder 15 controls the movement of the moving rod 16, causing the moving rod 16 to drive the first connecting plate 17 to move. When the first connecting plate 17 moves, it drives the moving sleeve 18 to move inside the support sleeve 19. When the moving sleeve 18 moves, the moving sleeve 18 drives the guide head 21 to move inside the spiral groove 20. The guide head 21 is limited by the spiral groove 20, causing the guide head 21 to deflect as it moves along with the spiral groove 20, thereby driving the moving sleeve 18 to deflect. When the moving sleeve 18 deflects, it limits the limit groove 23 through the limiting plate 22, driving the support shaft 55 to rotate. When the support shaft 55 rotates, it drives the fixed rod 26 and the liquid baffle 24 to rotate. When the liquid baffle 24 rotates inside the piston housing 11, the opening size of the through hole 25 is controlled by the relative angle between the liquid baffle 24 and the piston housing 11. When the opening of the through hole 25 is smaller, the resistance is greater when the buffer liquid flows through the through hole 25, and vice versa, the resistance is smaller. In this way, the size of the damping effect when the piston housing 11 moves is controlled, thereby adjusting the buffering effect on the third guide rail 5. When the third guide rail 5 only ascends and descends, the opening of the through hole 25 is increased to reduce the resistance for quick movement. When performing welding movement, the opening of the through hole 25 is reduced to increase the resistance, thereby improving the damping effect, enhancing the stability of the third guide rail 5 during movement, improving the welding quality of the welding machine 7, facilitating the adjustment of the damping effect according to different application scenarios, adapting to different working scenarios, and being convenient to use.
