Description

Technical Field

[0001] The invention belongs to the field of welding tools, and in particular relates to an auxiliary welding device for a steel pipe tower. Background Art

[0002] As an important supporting structure for modern overhead transmission lines, steel pipe towers play an indispensable role in the construction of power facilities. This type of tower is mainly composed of steel pipes as the main load-bearing components, supplemented by a lattice structure composed of other materials such as steel sections. It not only ensures the stability and safety of the transmission line, but also effectively meets the distance requirements between the conductor and the ground and objects, and can withstand the weight and external forces from the conductor, lightning rod and the tower itself.

[0003] However, welding has always been a critical and complex link in the manufacturing process of steel pipe towers. Especially when welding reinforcing plates and flanges at both ends of the steel pipes, the welding quality of these components is not only directly related to the overall structural strength of the steel pipe tower, but also has an important impact on its subsequent installation, operation and maintenance. Due to the large size of the steel pipe tower, the traditional welding method usually relies on large lifting equipment such as cranes or cranes to lift the steel pipes, and then workers manually align the flanges for welding. This operation method is not only inefficient, but also has high construction costs.

[0004] What is even more difficult is that in order to ensure the quality of the weld between the flange and the steel pipe, the steel pipe tower needs to be constantly rotated during the welding process to achieve uniform welding of the annular weld. When the steel pipe is lifted for welding by hoisting equipment, each rotation of the steel pipe requires the steel pipe to be dropped first, adjusted and lifted again. This is not only cumbersome, time-consuming and laborious, but also the frequent lifting and dropping can easily cause the flange to deform, especially in the early stage of welding, when the weld has not yet been fully solidified and the connection between the flange and the steel pipe is not yet firm. At this time, if the steel pipe tower falls, the lower end of the flange will be under great pressure, which is very likely to cause deformation, thus affecting the welding quality and the stability of the overall structure.

[0005] In order to solve the above problems, the operators have tried to introduce roller racks as auxiliary tools. The roller rack can greatly simplify the welding process of the annular weld and improve the welding efficiency by driving the weldment to rotate. However, since most steel pipe towers are multi-faceted pipe structures, such as Figure 1 As shown, the outer surface of the steel pipe tower has multiple side edges. When the side edges rotate on the roller frame, vibration is very likely to occur, which not only affects the welding accuracy, but also may cause potential damage to the structure of the steel pipe tower. In addition, the lower end of the prismatic steel pipe tower is large and the upper end is small. When the roller frame is used for welding, it is not easy to determine the position of the flange, which further increases the difficulty of rotating the steel pipe tower. Summary of the invention

[0019] 1) The present invention places a steel pipe tower with a polygonal pipe structure inside a semicircular roller with a cylindrical structure on the outside, and uses a tightening bolt to tighten the polygonal pipe, thereby realizing rotational welding of the polygonal pipe and the flange, avoiding the problem of low welding efficiency and easy deformation of the flange caused by repeated lifting of the lifting tool, as well as the problem of the bumpy vibration of the polygonal pipe caused by the rotation of the traditional roller frame affecting the welding accuracy of the flange.

[0020] 2) By arranging a motor on one side of the support seat to drive the support roller and the semicircular roller to rotate automatically, manual rotation of the semicircular roller is avoided, and the labor intensity of the operators is reduced; in addition, by arranging gears on both sides of the support roller and arranging gear rings meshing with the gears on both sides of the semicircular roller, slipping is avoided when the semicircular roller rotates.

[0021] 3) A lifting mechanism is set on the U-shaped base to realize the lifting of the support seat, which is not only convenient for adjusting the horizontality of the two ends of the polygonal tube, but also convenient for operators with different heights and working habits.

[0025] 7) By setting up a rib plate clamp and using it to clamp the rib plate during rib plate welding, the risk of burns to workers caused by high temperature during hand-held rib plate welding is avoided, while ensuring the stability of the rib plate during welding.

[0026] 8) A plug rod inserted into the through hole of the flange is provided on one side of the fixed plate, and the position of the plug rod can be adjusted according to the position of the through hole of the flange, which not only ensures the stability of the connection between the rib plate clamp and the flange, but also effectively prevents welding slag from splashing into the through hole of the flange during rib plate welding.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0040] like Figure 2 As shown, a steel pipe tower auxiliary welding device includes at least two support seats 2, and multiple support seats 2 are supported at multiple positions of the polygonal tube 1 to ensure the stability of the support seats 2 supporting the polygonal tube 1. Figure 3 As shown, support rollers 21 are rotatably mounted on both sides of the support seat 2, and a rotating roller is arranged between the support rollers 21 on both sides. The rotating roller is formed by connecting two semicircular rollers 24, and a plurality of tightening bolts 25 are threadedly connected to the semicircular rollers 24. Figure 4As shown, a ball joint 251 is provided at the lower end of the tightening bolt 25, and a tightening plate 252 is connected to one end of the ball joint 251. One side of the tightening plate 252 presses the outer wall of the polygonal tube 1. The ball joint 251 can adapt to the taper of the polygonal tube 1 to ensure the tightness of the tightening plate 252 and the polygonal tube 1, thereby ensuring the stability of the support seat 2 clamping the polygonal tube 1; a movable seat 3 is provided at the lower part of the support seat 2, and the movable seat 3 includes a U-shaped base 31. A movable wheel 32 is provided at the lower part of the U-shaped base 31 to facilitate the movement of the support seat 2.

[0041] In the present technical solution, the polygonal tube 1 is placed in a semicircular roller 24, two semicircular rollers 24 are connected to form a cylindrical roller, and the tightening bolts 25 are used to tighten the polygonal tube 1, so that the polygonal tube 1 is stably clamped inside the semicircular roller 24; when welding the flange 11, it is only necessary to rotate the semicircular roller 24 to realize the rotation of the polygonal tube 1, thereby satisfying the rotational welding of the polygonal tube 1 and the flange 11, avoiding the problem of low welding efficiency caused by repeated lifting of lifting tools, and the problem of deformation of the flange 11, as well as the problem of the bumpy vibration of the polygonal tube 1 caused by the rotation of the traditional roller frame affecting the welding accuracy of the flange 11.

[0042] like Figure 3 As shown, a motor 23 is provided on one side of at least one support seat 2. In the present embodiment, in order to ensure the smooth rotation of the polygonal tube 1, motors 23 are provided on one side of the support seats 2 at both ends of the polygonal tube 1. The motor 23 is connected to one of the support rollers 21 in the support seat 2. When the flange 11 is welded, the motor 23 drives the support roller 21 to rotate, thereby driving the semicircular roller 24 to rotate, avoiding manual rotation of the semicircular roller 24 and reducing the labor intensity of the operators.

[0043] like Figure 3 As shown, gears 22 are provided on both sides of the support roller 21, and semicircular gear rings 29 are provided on both sides of the semicircular roller 24, and the gears 22 are meshed with the semicircular gear rings 29; due to the heavy weight of the steel pipe tower, by arranging gears 22 on both sides of the support roller 21 and arranging gears meshed with them on both sides of the semicircular roller 24, the phenomenon of slipping when the support roller 21 drives the semicircular roller 24 to rotate, especially in the initial stage of rotation, is avoided, thereby ensuring the consistency and stability of the rotation welding of the polygonal tube 1 and the flange 11.

[0044] like Figure 3 As shown, a positioning hole 241 is provided on one end face of the semicircular roller 24, and a positioning pin 242 is provided on the other end face of the semicircular roller 24. The positioning holes 241 and the positioning pins 242 of the two semicircular rollers 24 are arranged alternately. When the two semicircular rollers 24 are connected, the positioning pins 242 are inserted into the positioning holes 241, thereby realizing rapid positioning of the semicircular rollers 24 and avoiding axial displacement after the two semicircular rollers 24 are connected, thereby enhancing the stability of the connection of the semicircular rollers 24.

[0045] The upper part of the U-shaped base 31 is provided with a lifting mechanism. Figure 7 As shown, the lifting mechanism includes a scissor frame 33, a U-shaped top plate 34 is provided on the upper part of the scissor frame 33, and the U-shaped base 31 and the U-shaped top plate 34 are fixedly connected with a first guide rod 37, wherein an upper slide 35 is slidably installed on the first guide rod 37 installed on the U-shaped top plate 34, and a lower slide seat 36 is slidably installed on the first guide rod 37 installed on the U-shaped base 31, one side of the scissor frame 33 is pivotally connected to the U-shaped top plate 34 and the U-shaped base 31, and the other side of the scissor frame 33 is connected to the upper slide seat 35 and the lower slide seat 36 respectively; one side of the U-shaped top plate 34 is rotatably connected to a first screw rod 38, and the first screw rod 38 is threadedly connected to the upper slide seat 35.

[0046] By rotating the first screw rod 38, the upper slide seat 35 is driven to slide left and right on the first guide rod 37 of the U-shaped top plate 34, and the lifting and lowering of the support seat 2 is realized by utilizing the extension and retraction of the scissor frame 33. This is not only convenient for adjusting the horizontality of the two ends of the polygonal tube 1, but also convenient for operators with different heights and working habits. In addition, by setting up a lifting mechanism, it is also beneficial to adjust the height of each section of the polygonal tube 1 when the multiple sections of the polygonal tube 1 are spliced ​​and welded, so that each section of the polygonal tube 1 is accurately aligned, thereby improving the accuracy and efficiency of the splicing and welding of the multiple sections of the polygonal tube 1.

[0047] like Figure 3 As shown, one side of the semicircular roller 24 is connected to an extension plate 26, and a U-shaped support 27 is provided on the extension plate 26.

[0048] When the polygonal tube 1 is welded with the flange 11, the flange 11 is clamped by the flange clamp 4, and the U-shaped bracket 41 of the flange clamp 4 is installed in the U-shaped support 27. The nut is screwed into the stud 28 to tighten the U-shaped bracket 41 and fix the flange 11 to one end of the polygonal tube 1. This avoids the operator holding the flange 11 for welding, which not only reduces the labor intensity of the operator, but also avoids displacement due to manual shaking or external force interference, thereby improving the welding accuracy and efficiency.

[0049] like Figure 6As shown, an adjustment groove 411 is provided on the upper part of the U-shaped bracket 41, and the stud 28 is slidably installed inside the adjustment groove 411, so as to adjust the telescopic length of the U-shaped bracket 41 according to the distance between the support seat 2 and the end of the polygonal tube 1, which not only improves the adaptability and flexibility of the flange clamp 4, but also ensures that the flange clamp 4 can be accurately positioned at the required position, and ensures the accuracy of welding the flange 11 and the polygonal tube 1; a first slide groove 412 is provided on the side of the U-shaped bracket 41, and a first slider 42 is slidably connected in the first slide groove 412, and the inner clamping plate 44 is fixedly installed on one side of the first slider 42, and a second screw rod 43 is threadedly connected in the middle part of the first slider 42, and the two ends of the second screw rod 43 are rotatably connected to the U-shaped bracket 41; by rotating the second screw rod 43, the first slider 42 is driven to move up and down in the first slide groove 412, so as to adjust the height of the inner clamping plate 44 and the outer clamping plate 45 according to the diameter of the flange 11, and improve the stability and reliability of the flange clamp 4 for clamping flanges 11 of different diameters.

[0050] like Figure 6 As shown, a hanging rod 48 is fixedly connected to the lower end of the inner clamping plate 44, and the hanging rod 48 is inserted into the through hole of the flange 11 to provide stable support and radial positioning for the flange 11, thereby improving the stability of the flange 11 during welding.

[0051] like Fig. 9 , Fig.10 As shown, it also includes a rib plate clamp 5, which includes a fixed plate 51, on which a plurality of support plates 54 are provided, the number of support plates 54 corresponds to the number of rib plates 12, the support plates 54 are fixedly connected to the fixed plate 51, or are detachably connected to the fixed plate 51 through a clamp, a second slide groove 541 is provided on the support plate 54, a third slider 542 is slidably connected in the second slide groove 541, and a fourth screw rod 543 is threadedly connected to the third slider 542; a plurality of swing arms 55 are rotatably connected to one side of the fixed plate 51, a swing pin 544 is rotatably connected to the middle part of the swing arm 55, and the lower end of the fourth screw rod 543 is rotatably connected to the swing pin 544; a third guide rod 57 is connected to one end of the swing arm 55, and side clamps 56 are symmetrically connected on both sides of the third guide rod 57, studs 58 are threadedly connected to the middle parts of the two side clamps 56, and the rib plate 12 is clamped between the two side clamps 56.

[0052] After the welding of the flange 11 is completed, the welding of the rib plate 12 is required. After the flange clamp 4 is removed, the rib plate 12 is clamped between the two side clamps 56, and then the fixing plate 51 is placed on one side of the flange 11, and the stud 58 is rotated to make the side clamp 56 clamp the rib plate 12, and the fourth screw 543 is rotated to drive the lower end of the swing arm 55 to move closer to one side of the flange 11, so that the rib plate 12 is close to the welding position, and the rib plate 12 is fine-tuned so that one side of the rib plate 12 is close to the flange 11, and the other side is close to the polygonal tube 1, and then the rib plate 12 is welded, avoiding the risk of burns to the operator caused by high temperature during the hand-held rib plate 12 welding operation, while ensuring the stability of the rib plate 12 during welding.

[0053] like Figure 8 , Fig. 9 As shown, one side of the fixed plate 51 is provided with a plurality of plug rods 531, and the plug rods 531 are inserted into the through holes of the flange 11.
