[0018] See also Figures 1 to 3 The present embodiment provides a liftable bracket for steel structure welding, including a fixed plate 1, a support plate 5 is provided directly above the fixed plate 1, mounting seats 4 are provided on both sides of both ends of the support plate 5, a sliding rod 44 is provided in the mounting seat 4, a lifting mechanism 3 is provided at the center of the bottom of the support plate 5, the lifting mechanism 3 includes a scissor-type arm frame 31, the scissor-type arm frame 31 is symmetrically installed on both sides of the bottom of the support plate 5, and hydraulic rods 2 are provided at the center of both ends of the bottom of the support plate 5.
[0019] The mounting seat 4 is fixedly mounted on both sides of the two ends of the support plate 5, a slot 41 is opened at the center of one side of the top of the mounting seat 4, a slide bar 44 is fixedly mounted at the center of the slot 41, and sliders 51 of the same shape and size as the slot 41 and plugged into each other are fixedly mounted on both sides of the two ends of the support plate 5, and the slider 51 is slidably mounted in the slot 41. It should be added that: the length of the sliding rod 44 is equal to the length of the slot 41, a through hole 511 is penetrated at the center of the top of the sliding block 51, and the sliding rod 44 is slidably installed in the through hole 511, and a movable groove 42 communicating with the slot 41 is penetrated near one side of one end of the mounting seat 4, and a vertical plate 512 of the same shape and size as the movable groove 42 and plugged into each other is fixedly installed near one end of one side of the sliding block 51, the vertical plate 512 is slidably installed in the movable groove 42, and one end of the vertical plate 512 is higher than one end of the mounting seat 4, and a horizontal plate 513 is fixedly installed on one side of one end of the vertical plate 512, and a positioning hole 514 is penetrated at the center of the surface of the horizontal plate 513, and a plurality of openings 43 communicating with the slot 41 are penetrated vertically downward at one end of the mounting seat 4, and the positioning holes 514 have the same aperture size as the openings 43, and a positioning rod 45 is slidably installed in the positioning holes 514 and the openings 43.
[0020] The slide bar 44 provides a guiding function when the support plate 5 is lifted and lowered, preventing the support plate 5 from deflecting or tilting during the lifting process. The support plate 5 is used to carry the staff, and its position can be adjusted by the lifting mechanism 3 to meet the welding requirements of different heights.
[0021] The hydraulic rod 2 is fixedly mounted at the centers of both ends of the top of the fixed plate 1, and the piston rods in the two hydraulic rods 2 are respectively fixedly mounted at the centers of both ends of the bottom of the support plate 5. It should be added that the hydraulic rod 2, as a power source, pushes the support plate 5 to move up and down through the extension and contraction of the piston rod, providing accurate and smooth lifting action.
[0022] The limiting brackets 32 are fixedly installed on both sides of the center of the top of the fixed plate 1, and a slide groove 321 is provided at the center of one side of the limiting bracket 32. It should be supplemented that: the scissor-type arm 31 is located between the two limiting brackets 32, and a plurality of threaded holes 322 are provided through the top of the limiting bracket 32 near one side, and a threaded rod 323 is installed in the threaded hole 322. The top diameter of the slide groove 321 is slightly smaller than the diameter of the cylinder 341, so that when the cylinder 341 moves in the slide groove 321, it will not run out of the limiting bracket 32.
[0023] The limiting bracket 32 guides and limits the cylinder 341 through the slide groove 321 to prevent the scissor-type arm frame 31 from deflecting or derailing during the lifting process, while providing support and protection for the lifting mechanism 3.
[0024] The scissor-type arm 31 is composed of a first arm and a second arm. A fixing member 35 is rotatably installed at the intersection of the first arm and the second arm. A fixing rod 33 is fixedly installed between the two first arms and between the two second arms near the bottom center. A rotating shaft 34 is fixedly installed between the two first arms and between the two second arms at the bottom center. Cylinders 341 are fixedly installed at both ends of the rotating shaft 34. The cylinder 341 is slidably engaged in the slide groove 321. It should be supplemented that the fixing member 35 is used to fix the first arm and the second arm. The fixing rod 33 is set to support the two first arms and the two second arms respectively. Make the first arm and the second arm more stable.
[0025] The two ends of the bottom of the support plate 5 are respectively fixedly mounted with hinge seats 36, the tops of the two first arms are rotatably mounted in the hinge seats 36 on both sides of one end of the bottom of the support plate 5 through the first mounting rod, and the tops of the two second arms are rotatably mounted in the hinge seats 36 on both sides of the other end of the bottom of the support plate 5 through the second mounting rod. It should be added that the hinge seats 36 are used to connect the scissor-type arm 31 and the support plate 5, realize the rotational connection between the top of the arm and the support plate 5, and ensure the movement coordination and stability between the lifting mechanism 3 and the support plate 5.
[0026] The specific use of the utility model is that first, the staff stands on the support plate 5 to perform welding operations. According to the height of the steel structure to be welded, the staff opens the hydraulic rod 2 through the controller to extend or retract the piston rod, thereby pushing the support plate 5 up or down. During the lifting process of the support plate 5, the combination of the slide bar 44 and the slide block 51 plays a guiding role to ensure that the support plate 5 is lifted and lowered smoothly without deviation or tilting. As the support plate 5 rises, the angle between the first arm and the second arm will gradually decrease, and the cylinder 341 will slide toward the middle in the slide groove 321 at the same time. When the support plate 5 is lifted to the required height, the threaded rod 323 is used to be threadedly installed in the threaded hole 322 to ensure that the first arm and the second arm will not move to both ends during the welding process of the support plate 5 to maintain stability. After the positioning hole 514 is aligned with the appropriate opening 43, the hydraulic rod 2 is stopped by the controller, and the positioning rod 45 is inserted to pass through the positioning hole 514 and the opening 43, thereby fixing the slider 51 at a certain position in the slot 41 to achieve the positioning of the support plate 5, so that the staff can fine-tune the height at any time as needed during the welding process. After the welding is completed, the threaded rod 323 is first removed from the threaded hole 322 by rotating the inner thread, and then the positioning rod 45 is pulled out from the positioning hole 514 and the opening 43 to release the positioning of the support plate 5, and then the controller of the hydraulic rod 2 is operated to make the support plate 5 drop to the lowest position. The angle between the first arm and the second arm will gradually increase as the support plate 5 drops. When the support plate 5 drops to a certain position, the hydraulic rod 2 stops, so that the staff leaves the support plate 5.
