Description

Technical Field

[0001] The present invention relates to the technical field of welding assistance, and specifically to a steel structure welding device. Background Art

[0002] In the welding of a flange and a tubular steel structure, it is necessary to move the tubular body to the position of the central circular hole on the flange plate. However, when welding the two, it is usually necessary to use an external assistance method to preferentially weld the initial connection. After the welding is fixed, the remaining part is welded to ensure that the tubular body does not displace. In most current such welding processes, there are still situations of instability, deviation, and inconvenience during the welding of the flange plate and the tubular body. Therefore, we urgently need a steel structure welding device to solve the above problems. Summary of the Invention

[0003] The object of the present invention is to provide a steel structure welding device, which provides an auxiliary tooling with high stability and accurate positioning, improving the processing efficiency.

[0004] To achieve the above object, the present invention is realized through the following technical solutions: A steel structure welding device includes a bottom plate. At the four corner positions on the upper surface of the bottom plate, linear tracks are fixedly installed, and sliders are slidably connected in the linear tracks. A hydraulic rod I is embedded in the linear track through a placement groove, and the output end of the hydraulic rod I is fixedly installed with the slider. Arc-shaped plates are fixedly installed on all four sliders, and an anti-slip component is arranged on the linear track;

[0005] The anti-slip component includes a circular groove, which is opened in the slider. A lifter is fixedly installed in the circular groove and within the slider, and the top end of the lifter is fixedly installed with the lower surface of the arc-shaped plate. A paste plate is fixedly installed on the upper surface of the linear track, and an anti-slip pad is fixedly installed on the paste plate;

[0006] When the lifter is lifted by an external force, the arc-shaped plate is separated from the anti-slip pad on the linear track. When the lifter is pressed downward by force, the arc-shaped plate comes into contact with the anti-slip pad on the linear track;

[0007] A positioning component I is arranged at the central position on the upper surface of the bottom plate, a positioning component II is arranged on the arc-shaped plate, and a clamping component is arranged inside the arc-shaped plate.

[0008] Through the above technical solutions, while the positioning component I functions to position the tubular body, it also completes the limiting effect. The positioning component II is used to assist the positioning component I to perform secondary positioning on the tubular body. The positioning component I positions the inner side of the tubular body, and the positioning component II positions the outer side of the tubular body. The clamping component functions to clamp the flange plate itself.

[0009] Preferably, the first positioning component includes a support frame fixedly installed at the center of the upper surface of the bottom plate. The top of the support frame is fixedly installed with a first placement plate. The output end of the second hydraulic rod is fixedly installed at the center of the upper surface of the first placement plate. A second placement plate is arranged above the first placement plate. The movable end of the second hydraulic rod is fixedly installed on the corresponding side surface of the second placement plate. An airbag is arranged between the first placement plate and the second placement plate, and the upper and lower ends of the airbag are respectively fixedly installed on the corresponding side surfaces of the first placement plate and the second placement plate. Movable devices are fixedly installed on the outer sides of the first placement plate and the second placement plate.

[0010] Through the above technical solution, the diameters of the first placement plate and the second placement plate are smaller than the diameter of the central through hole of the flange plate.

[0011] Preferably, one end of a movable rod is rotatably connected to the movable device through a bearing. The other end of the movable rod, on the side far from the airbag, is fixedly installed with a mounting plate. When the airbag inflates and expands, the corresponding side surfaces of the two mounting plates come into contact. When the airbag deflates, the opposite side surfaces of the two corresponding mounting plates are in line contact. Arc plates are fixedly installed on the outer sides of the two mounting plates, on the sides far from the airbag. An air inlet pipe is fixedly communicated with the second placement plate. A cylinder is movably installed at the center of the upper surface of the second placement plate. One end of a branch air pipe is fixedly communicated with the cylinder, and the other end of the branch air pipe is movably communicated with the air inlet pipe. A grip is fixedly installed at the top of the cylinder.

[0012] Preferably, a drain pipe is also fixedly communicated with the second placement plate. A drain valve is fixedly installed in the drain pipe on the second placement plate. A toggle rod is fixedly installed on the drain valve. A rectangular through groove is formed at the center position of the arc plate, and a row of wheels is fixedly installed on the inner wall of the rectangular through groove. The second positioning component includes a placer fixedly installed on the upper surface of the arc plate. A first cross bar is rotatably connected to the placer through a bearing. The end of the first cross bar, far from the placer, is fixedly installed with a coupler. A second cross bar is rotatably connected to the coupler through a bearing. A first rotator is fixedly installed on the lower surface of the second cross bar. The output end of the third hydraulic cylinder is rotatably connected to the first rotator. A chute is formed on the side surface of the first cross bar corresponding to the first rotator. A driving block is slidably connected in the chute. A second rotator is fixedly installed on the driving block. The movable end of the third hydraulic cylinder is fixedly installed with the second rotator.

[0013] Through the above technical solution, when the airbag is full, the arc plate is in a state of being in contact with the inner wall of the tubular body. Because when the airbag is in a full-air state, it will maintain an upright state. After the bottom end of the airbag contacts the inner wall of the through hole on the flange plate, the top end of the airbag is in an upright state, which is convenient for the docking of the tubular body and the flange plate.

[0014] Preferably, a positioning plate is fixedly installed at one end of the second cross bar away from the coupler. The clamping assembly includes an arc-shaped groove, which is opened in the arc-shaped plate. A protective pad is fixedly installed on the bottom wall of the arc-shaped groove. A threaded hole is opened on the upper surface of the arc-shaped plate, and a screw rod is threadedly connected in the threaded hole. The bottom end of the screw rod is rotatably connected to a limiting plate through a bearing hole.

[0015] Preferably, a knob is fixedly installed at the top end of the screw rod.

[0016] By adopting the foregoing technical solutions, the beneficial effects of the present invention are as follows:

[0017] In this steel structure welding device, through the mutual cooperation and positioning and limiting effects of the positioning component one and the positioning component two, more accurate docking of the tubular body and the flange is achieved, avoiding the debugging work and the deviation during processing that are required for manual docking or using other auxiliary docking methods, and improving the processing efficiency and welding accuracy.

[0032] Please refer to Figures 1-7 , the present invention provides a technical solution: a steel structure welding device, including a bottom plate 1.

A paste plate 63 is fixedly installed on the upper surface of the linear track 2, and an anti-slip pad 64 is fixedly installed on the paste plate 63;

[0034] When the lifter 62 is lifted by an external force, the arc-shaped plate 5 is separated from the anti-slip pad 64 on the linear track 2. When the lifter 62 is pressed downward by force, the arc-shaped plate 5 contacts the anti-slip pad 64 on the linear track 2;

[0035] A first positioning component 7 is arranged at the central position of the upper surface of the bottom plate 1, a second positioning component 8 is arranged on the arc-shaped plate 5, and a clamping component 9 is arranged within the arc-shaped plate 5;

[0036] While the positioning component 1-7 functions to position the tubular body, it also completes the limiting effect.

The top end of the support frame 71 is fixedly installed with a first placement plate 72. The output end of a second hydraulic rod 73 is fixedly installed at the center position of the upper surface of the first placement plate 72. A second placement plate 74 is arranged above the first placement plate 72. The movable end of the second hydraulic rod 73 is fixedly installed on the corresponding side surface of the second placement plate 74. An airbag 75 is arranged between the first placement plate 72 and the second placement plate 74, and the upper and lower ends of the airbag 75 are respectively fixedly installed on the corresponding side surfaces of the corresponding first placement plate 72 and the second placement plate 74.

Arc plates 78 are fixedly installed on the outer sides of both mounting plates 77, on the side far from the airbag 75. An air inlet pipe 79 is fixedly connected to the second placement plate 74. A cylinder 710 is movably installed at the center position of the upper surface of the second placement plate 74. One end of a branch air pipe 711 is fixedly connected to the cylinder 710, and the other end of the branch air pipe 711 is movably connected to the air inlet pipe 79. A handle 712 is fixedly installed at the top end of the cylinder 710.

[0039] An exhaust pipe 713 is also fixedly connected to the second placement plate 74, and an exhaust valve 714 is fixedly installed in the exhaust pipe 713 on the second placement plate 74. A toggle rod 715 is fixedly installed on the exhaust valve 714. A rectangular through groove 716 is formed at the center of the arc plate 78, and a row of wheels 717 is fixedly installed on the inner wall of the rectangular through groove 716. The second positioning component 8 includes a placer 81, and the placer 81 is fixedly installed on the upper surface of the arc plate 5. A first cross bar 82 is rotatably connected in the placer 81 through a bearing. A coupler 83 is fixedly installed at the end of the first cross bar 82 away from the placer 81. A second cross bar 84 is rotatably connected to the coupler 83 through a bearing. A first rotator 85 is fixedly installed on the lower surface of the second cross bar 84. The output end of a third hydraulic cylinder 86 is rotatably connected to the first rotator 85. A chute 810 is formed in the side surface of the first cross bar 82 corresponding to the first rotator 85. A driving block 87 is slidably connected in the chute 810. A second rotator 88 is fixedly installed on the driving block 87. The movable end of the third hydraulic cylinder 86 is fixedly installed with the second rotator 88. When the airbag 75 is fully inflated, the arc plate 78 is in a fitting state with the inner wall of the tubular body. Because the airbag 75 will maintain an upright state when it is fully inflated, after the bottom end of the airbag 75 contacts the inner wall of the through hole on the flange, the top end of the airbag 75 is in an upright state, which is convenient for the docking of the tubular body and the flange.

[0040] A positioning plate 89 is fixedly installed at the end of the second cross bar 84 away from the coupler 83. The clamping component 9 includes an arc groove 91, and the arc groove 91 is formed in the arc plate 5. A protective pad 92 is fixedly installed on the inner bottom wall of the arc groove 91.

The bottom end of the screw 94 is rotatably connected to a limiting plate 95 through a bearing hole. A knob 96 is fixedly installed at the top end of the screw 94.

[0041] When the steel structure welding device is working, place the flange on the bottom plate 1, and the central through-hole of the flange is located on the support 71 of the bottom plate 1. Pick up the flange, move the arc-shaped plate 5 inward through the slider 3 driven by the hydraulic rod 4 in the linear track 2, and make it fit with the outer side of the flange. The bottom wall of the flange contacts the protective pad 92 in the arc-shaped groove 91 of the arc-shaped plate 5, and rotate the knob 96. The screw rod 94 cooperates with the threaded hole 93 to move downward and drive the limiting plate 95 to fit with the surface of the flange to complete the limiting. Also, sleeve the tubular body on the support frame, and the bottom end of the tubular body contacts the surface of the flange. Grab the handle 712 and use the air cylinder 710 to inflate the airbag 75. When the airbag 75 is inflated, the hydraulic rod 2 73 is driven upward by the gas extrusion. The height of the airbag 75 continuously increases and expands outward. The mounting plate 77 is in a straight state under the outward drive of the movable rod 76, and the arc-shaped plate 78 contacts the inner wall of the tubular body. The positioning plate 89 on the cross bar 2 84 is made to fit with the outer wall of the tubular body through the mutual cooperation of the hydraulic cylinder 3 86, the coupler 83, the rotator 1 85, and the rotator 2 88, so as to complete the fixation of the flange itself as a whole. When disassembly is required, just open the clamping assembly 9 in the arc-shaped plate 5, and cooperate with the outward movement of the slider 3 in the linear track 2, and use the row wheel 717 on the arc-shaped plate 78 to take out the welded flange pipe seat upward. When complete disassembly is carried out, repeat the above steps, press the toggle rod 715 to open the air release valve 714, and exhaust the airbag 75.
