Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding device for power transmission towers that is easy to level. Background Technology

[0002] Power transmission towers are tower-shaped structures used for power transmission. Their structural characteristics are that all types of towers are spatial truss structures. The members are mainly composed of single equilateral angle steel or combined angle steel. The members are connected by coarse bolts, which are connected by shear force. The entire tower is composed of angle steel, connecting steel plates and bolts. Some components, such as the tower feet, are made by welding several steel plates into a single assembly.

[0003] When welding two steel plates, the existing fixing method usually involves fixing the two steel plates laterally and then welding them on their welding surfaces. After one side is welded, the two steel plates are reversed by a reversing mechanism. This fixing method means that only one side can be welded at a time, which reduces welding efficiency. In addition, cracks may occur on the two newly welded surfaces during the reversing process. Utility Model Content

[0033] Please see Figure 1-3 This utility model provides a technical solution: a power tower welding device that is easy to level, including a support base plate 1, two dual-axis motors 9 and a steel plate 17. The support base plate 1 has sliding grooves 7 on both the left and right sides. The two dual-axis motors 9 have output ends at the front and rear. The leveling component is set on the support base plate 1.

[0034] The movable fixing device is mounted on two dual-axis motors 9. The movable fixing device includes two threaded rods 10, which are respectively fixedly connected to the front output ends of the two dual-axis motors 9. The front ends of the two threaded rods 10 are rotatably connected to a first fixing plate 5, and the two first fixing plates 5 are fixedly connected to the support base plate 1.

[0035] Among them, the outer walls of the two threaded rods 10 are threaded with movable sleeves 6, and the opposite surfaces of the two movable sleeves 6 are fixedly connected with sliders 11, and the two sliders 11 are slidably connected to the corresponding sliding grooves 7 respectively.

[0036] Furthermore, the mobile fixing device also includes two fixing blocks 12, and a second fixing plate 13 is fixedly connected to the upper surface of the two fixing blocks 12. Two multi-stage telescopic cylinders 14 are fixedly connected to the upper surface of the second fixing plate 13.

[0037] Among them, the output ends of the two multi-segment telescopic cylinders 14 are fixedly connected to a third fixing plate 15, the lower surface of the third fixing plate 15 is fixedly connected to a first concave plate 18, and the top of the first concave plate 18 is fixedly connected to two fixing rubber pads 19.

[0038] Furthermore, the movable fixing device also includes a second concave plate 22, which is fixedly connected to the upper surface of the second fixing plate 13, and mounting plates 3 are fixedly connected to both the left and right sides of the second concave plate 22.

[0039] Both mounting plates 3 are fixedly connected to the second fixed plate 13, and both mounting plates 3 have an electric hydraulic rod 4 fixedly connected to their upper surfaces. The output ends of both electric hydraulic rods 4 slide through the concave part of the second concave plate 22.

[0040] Furthermore, the movable fixing device also includes two fixing plates 21, which are respectively fixedly connected to the output ends of the two electric hydraulic rods 4;

[0041] Among them, two springs 20 are fixedly connected to the opposite surfaces of the two fixed clamping plates 21, and all four springs 20 are fixedly connected to the second concave plate 22.

[0042] The number of mobile fixed devices is two, and the two mobile fixed devices are set up in a front-to-back mirror configuration.

[0043] Furthermore, the leveling component includes a third concave plate 26, which is fixedly connected to the upper surface of the support base plate 1, and a rectangular block 16 is provided on the upper surface of the third concave plate 26.

[0044] Two connecting plates 25 are fixedly connected to both the left and right sides of the rectangular block 16, and all four connecting plates 25 are fixedly installed on the upper surface of the third concave plate 26 by fixing threads.

[0045] Furthermore, a steel plate inlet groove 23 is provided on the rectangular block 16, and the steel plate inlet groove 23 can be provided according to the steel plate of different thicknesses;

[0046] The rectangular block 16 has welding grooves 24 on both its left and right sides that communicate with the steel plate entry groove 23.

[0047] The lower surface of the support base plate 1 is fixedly connected with four support legs 2.

[0048] Furthermore, when fixing the two steel plates 17, the steel plates are placed on the concave part of the second concave plate 22, and the front end of the steel plate 17 is inserted into the steel plate inlet groove 23. The steel plate inlet groove 23 can be selected according to the actual thickness of the steel plate 17 to replace the rectangular block 16. Then, the two electric hydraulic rods 4 are activated to fix the lower side of the steel plate 17 through the two fixing clamps 21. Then, the two multi-stage telescopic cylinders 14 are activated. The two multi-stage telescopic cylinders 14 drive the third fixing plate 15 and the first concave plate 18 to move downward. The concave part of the first concave plate 18 will contact the upper surface of the steel plate 17, and the steel plate 17 will be firmly fixed on the second concave plate 22. The installation method of the two steel plates 17 is the same. Then, the two dual-axis motors 9 are activated. The front and rear output shafts of the two dual-axis motors 9 rotate in opposite directions. The two dual-axis motors 9 drive the four threaded rods 10 to rotate. The four threaded rods 10 drive the two left and right corresponding moving sleeves 6. The two corresponding left and right moving sleeves 6 move to relative positions through the fixed block 12, driving the two second fixed plates 13 to move to relative positions. This causes the two steel plates 17 to move to relative positions through the inner wall of the steel plate entry groove 23. When the opposite surfaces of the two steel plates 17 come into contact, the two welding robots can be started to weld the opposite surfaces of the two steel plates 17 through the two welding grooves 24. By fixing the two steel plates 17 vertically, compared with horizontal fixing, not only can the left and right sides of the two steel plates 17 be welded simultaneously, but it is also not necessary to flip the two steel plates after welding, which improves welding efficiency. By setting the rectangular block 16 and the steel plate entry groove 23, the steel plate entry groove 23 plays an automatic leveling role for the two steel plates 17, preventing positional deviations of the two steel plates 17 during the alignment process, which would result in the two steel plates 17 not being on the same plane after welding, thus improving welding quality.

[0049] Working principle: When fixing the two steel plates 17, the steel plates are placed on the concave part of the second concave plate 22. The front end of the steel plate 17 is then inserted into the steel plate entry groove 23. The steel plate entry groove 23 can be selected according to the actual thickness of the steel plate 17 to replace the rectangular block 16. Then, the two electric hydraulic rods 4 are activated to fix the lower side of the steel plate 17 through the two fixing clamps 21. Then, the two multi-stage telescopic cylinders 14 are activated. The two multi-stage telescopic cylinders 14 drive the third fixing plate 15 and the first concave plate 18 to move downward. The concave part of the first concave plate 18 will contact the upper surface of the steel plate 17, firmly fixing the steel plate 17 on the second concave plate 22. The installation method of each steel plate 17 is the same. Then, two dual-axis motors 9 are started. The front and rear output shafts of the two dual-axis motors 9 rotate in opposite directions. The two dual-axis motors 9 drive four threaded rods 10 to rotate. The four threaded rods 10 drive two left and right corresponding moving sleeves 6 to move to their relative positions. The two left and right corresponding moving sleeves 6 drive two second fixed plates 13 to move to their relative positions through the fixed block 12. This causes the two steel plates 17 to move to their relative positions through the inner wall of the steel plate entry groove 23. When the opposite surfaces of the two steel plates 17 come into contact, two welding robots can be started to weld the opposite surfaces of the two steel plates 17 through the two welding grooves 24.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
