Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding device for straight columns of iron towers. Background Technology

[0002] The vertical columns of the iron tower are the core vertical components that make up the main support structure of various iron towers. They are usually made of steel and assembled by welding, bolting and other methods. They stand vertically on the foundation at the bottom of the iron tower and are the key part that bears the overall weight of the iron tower, wind load, snow load and the weight of the upper equipment.

[0003] In the prior art, a Chinese utility model patent with publication number "CN213105069U" and patent name "A Welding Device for Straight Columns of Iron Towers" describes a device that includes "a fixed base plate, a movable base plate, a Y-shaped bracket, a lead screw, an adjusting wheel, a pressure roller mechanism, a flange positioning frame, and a welding torch mechanism; a rectangular slide rod is fixedly connected to one end of the movable base plate; the rectangular slide rod is slidably connected to the slide rod groove of the fixed base plate; a Y-shaped bracket and a pressure roller mechanism are respectively connected to the top of the fixed base plate and the top of the movable base plate; two..." A Y-shaped bracket is located in the middle of the inner sides of the two pressure roller mechanisms; the other end of the movable seat plate is fixedly connected to a flange positioning frame; the welding gun mechanism is movably connected to the inner side of the flange positioning frame; one end of the lead screw is fixedly connected to the adjusting wheel; the middle of the lead screw is rotatably connected to the middle of the movable seat plate; the other end of the lead screw is threaded into the internal threaded through hole of the fixed seat plate; a vertical frame is fixedly connected to each side of the bottom end of the fixed seat plate; a traveling wheel is rotatably connected to each side of the bottom end of the movable seat plate, etc.

[0004] Although this technical solution replaces traditional manual welding with mechanical structure, it improves the efficiency and accuracy of single-end welding to a certain extent and reduces the intensity of manual labor;

[0005] However, in actual production applications, because it only has one set of flange positioning frame and welding gun mechanism, it can only perform welding operations on one end of the tower column. Both ends of the tower column need to be welded with flanges to meet assembly requirements. Therefore, after the welding of the flange at one end of the column is completed, the operator needs to remove the tower column from the device as a whole, turn it 180 degrees and then re-hoist or place it on the Y-shaped bracket so that the unwelded end is aligned with the flange positioning frame and welding gun mechanism before welding the flange at the other end can be carried out. This operation method is not only cumbersome and time-consuming, but also reduces the overall production efficiency.

[0006] Therefore, in order to solve the above-mentioned technical problems, this utility model proposes a welding device for straight columns of iron towers. Utility Model Content

Each lifting plate is independently equipped with an L-shaped plate pushing mechanism driven by a first cylinder, a lateral movement mechanism controlled by a second cylinder, and a welding gun, forming a dual-station synchronous operation system. This structural layout allows the device to simultaneously perform flange positioning and welding operations on both ends of the tower column, completely solving the technical defects of the prior art that requires repeated disassembly and reassembly of the tower column. In actual production, operators only need to hoist the tower column onto the adjustable welding roller frame once, adjust the distance between the flange seats on both sides to complete the positioning, and then start the dual-station welding system to simultaneously complete the flange welding at both ends of the tower column.

[0030] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0031] like Figure 1 - Figure 6 As shown, a welding device for a straight column of a steel tower includes a base 1;

[0032] The base 1 has several adjustable welded roller frames 2 on its top. Two columns 3 are fixedly connected to the top two sides of the base 1. A crossbeam 4 is fixedly connected between adjacent columns 3. Two lifting plates 17 are provided above the base 1. A movable plate 11 is provided above the lifting plates 17. An adjusting component for controlling the two movable plates 11 to move in opposite directions is installed between the crossbeams 4.

[0033] The top of the movable plate 11 is equipped with a lifting component for realizing the vertical movement of the lifting plate 17;

[0034] A rotating disk 22 is rotatably connected to the opposite surfaces of the two lifting plates 17, and a flange seat 24 is fixedly connected to the side of the rotating disk 22 away from the lifting plate 17. A fixed plate 26 is fixedly connected to one side of the lifting plate 17 and above the flange seat 24. An L-shaped plate 29 is provided below the fixed plate 26, and a pusher for driving the L-shaped plate 29 to move downward is installed on the top of the fixed plate 26.

[0035] A mounting base 33 is slidably connected to the lower part of the L-shaped plate 29. A welding gun 35 is fixedly connected to one side of the mounting base 33. A side pusher for controlling the horizontal movement of the mounting base 33 is installed on one side of the L-shaped plate 29.

[0036] like Figure 3 - Figure 5 As shown, the adjusting component includes a protective shell 5, a bidirectional lead screw 7, a drive motor 9, and a limiting slide rod 10. A rotating hole 6 is provided on one side of the crossbeam 4. Rotating rods 8 are fixedly connected to both ends of the bidirectional lead screw 7, and the rotating rods 8 are rotatably connected to the rotating hole 6. The drive motor 9 is fixedly connected to the outer wall of one side of the crossbeam 4, and the output end of the drive motor 9 is fixedly connected to the rotating rod 8 at the opposite end of the bidirectional lead screw 7 through a coupling. A limiting slide rod 10 is fixedly connected between the crossbeams 4 and on one side of the bidirectional lead screw 7. Protective shells 5 are fixedly connected between the crossbeams 4 and outside the bidirectional lead screw 7 and the limiting slide rod 10. Two connecting seats 12 are fixedly connected to the bottom of the two movable plates 11. A sliding hole 13 is provided on the side wall of one connecting seat 12 to slide with the limiting slide rod 10, and a screw hole 14 is provided on the side wall of the other connecting seat 12 to thread with the bidirectional lead screw 7.

[0037] When the drive motor 9 starts, its output end drives the rotating rods 8 at both ends of the double-acting screw 7 through the coupling to rotate in the rotating hole 6 on one side of the crossbeam 4. When the double-acting screw 7 rotates under the drive of the rotating rod 8, the connecting seat 12 at the bottom of the two movable plates 11 forms a threaded transmission with the double-acting screw 7 through the side wall screw hole 14. At the same time, the connecting seat 12 on the other side forms a sliding fit with the limiting slide rod 10 between the crossbeam 4 through the sliding hole 13, which restricts the rotational freedom of the movable plate 11 and only allows it to move in opposite directions along the axial direction of the double-acting screw 7 and the limiting slide rod 10, so as to ensure that the flange on the flange seat 24 can be tightly connected to both ends of the iron tower column and adapt to iron tower columns of different lengths.

[0038] Furthermore, the protective shell 5 is installed outside the bidirectional lead screw 7 and the limiting slide bar 10, which can prevent the intrusion of impurities generated during welding and prevent them from affecting normal use;

[0039] like Figure 5 As shown, the lifting component includes a hydraulic cylinder 16, a connecting plate 18, and a first guide rod 19. The hydraulic cylinder 16 is fixedly connected to the top of the movable plate 11. The connecting plate 18 is fixedly connected to the side of the lifting plate 17 away from the rotating disk 22, and the connecting plate 18 is fixedly connected to the output end of the hydraulic cylinder 16. Two first guide rods 19 are fixedly connected to the top of the connecting plate 18, and the first guide rods 19 are inserted and installed through the corresponding first guide holes 15 opened on the top of the movable plate 11.

[0040] The hydraulic cylinder 16 is fixed on the top of the movable plate 11. When its output end extends or retracts, it directly drives the connecting plate 18 on one side of the lifting plate 17 to move vertically. The two first guide rods 19 on the top of the connecting plate 18 form an interlocking fit with the first guide hole 15 on the top of the movable plate 11, which restricts the horizontal offset of the connecting plate 18 and ensures that the direction of movement is always vertical.

[0041] Furthermore, through the stable driving force of the hydraulic cylinder 16, the hydraulic cylinder 16 is driven by the existing hydraulic drive system to realize the vertical height adjustment of the lifting plate 17, so that the rotating disk 22 and flange seat 24 on the lifting plate 17 can be precisely aligned with the end height of the iron tower columns of different diameters.

[0042] like Figure 5 As shown, the side wall of the lifting plate 17 is provided with mounting holes 20, and a bearing 21 is fixedly connected in the mounting holes 20. A rotating shaft 23 is fixedly connected to the side of the rotating disk 22 near the lifting plate 17, and the rotating shaft 23 is inserted and fixed to the inner ring of the bearing 21. The flange seat 24 is fixedly connected to the side of the rotating disk 22 away from the rotating shaft 23 by bolts and nuts. On the side of the flange seat 24 away from the rotating shaft 23, pins 25 corresponding to the flange holes on the flange are fixedly connected in a ring array, and the pins 25 are inserted into the flange holes.

[0043] The rotating disk 22 is fixed by the inner ring of the bearing 21 in the mounting hole 20 of the lifting plate 17 through the rotating shaft 23 on one side, so that the rotating disk 22 can rotate flexibly around the rotating shaft 23. The flange seat 24 is fixed to the side of the rotating disk 22 away from the rotating shaft 23 by bolts and nuts. The pins 25 in the annular array on its surface are inserted into the flange hole of the flange to be welded, so as to realize the rapid positioning of the flange. Different flanges can be adapted by replacing the flange seat 24.

[0044] Furthermore, the insertion and engagement of the pin 25 with the flange hole quickly completes the positioning and fixing of the flange on the flange seat 24, preventing the flange from shifting during welding. The bearing 21 reduces the frictional resistance between the rotating shaft 23 and the lifting plate 17, allowing the rotating disk 22 to rotate smoothly and synchronously with the tower column. Combined with the adjustable welding roller frame 2, it enables circumferential welding of the column and the flange, ensuring uniform and continuous weld seam.

[0045] like Figure 5 and Figure 6 As shown, the pusher includes a first cylinder 28 and a second guide rod 30. The first cylinder 28 is fixedly connected to the top of the fixed plate 26. Two second guide rods 30 are fixedly connected to the top of the horizontal part of the L-shaped plate 29. The second guide rods 30 are inserted into the corresponding second guide holes 27 opened on the top of the fixed plate 26. The output end of the first cylinder 28 is fixedly connected to the L-shaped plate 29.

[0046] The first cylinder 28 is fixed to the top of the fixed plate 26. When its output end extends or retracts, it directly drives the L-shaped plate 29 to move vertically. The two second guide rods 30 at the top of the horizontal part of the L-shaped plate 29 form an interlocking fit with the second guide hole 27 at the top of the fixed plate 26, which restricts the horizontal sway of the L-shaped plate 29 and ensures the accuracy of the vertical movement trajectory.

[0047] Furthermore, through the precise drive of the first cylinder 28, which is driven by the existing pneumatic control system, the vertical height of the welding gun 35 below the L-shaped plate 29 is adjusted, so that the welding gun 35 can quickly approach or move away from the butt weld of the column and the flange. The cooperation between the second guide rod 30 and the second guide hole 27 ensures that the L-shaped plate 29 moves smoothly, avoids the welding gun 35 from deviating and causing weld deviation, and improves the welding quality.

[0048] like Figure 5 and Figure 6 As shown, the side pusher includes a T-shaped guide rail 31 and a second cylinder 32. The T-shaped guide rail 31 is fixedly connected to the bottom of the horizontal part of the L-shaped plate 29, and the second cylinder 32 is fixedly connected to the outer wall of the vertical part of the L-shaped plate 29. The output end of the second cylinder 32 is fixedly connected to the mounting base 33, and the mounting base 33 is slidably connected to the T-shaped guide rail 31 through the T-shaped guide groove 34 opened at the top. The welding gun 35 is fixedly connected to the side of the mounting base 33 away from the output end of the second cylinder 32.

[0049] The second cylinder 32 is fixed to the outer wall of the vertical part of the L-shaped plate 29. When its output end extends or retracts, it drives the mounting base 33 to move. The mounting base 33 forms a sliding fit with the T-shaped guide rail 31 at the bottom of the horizontal part of the L-shaped plate 29 through the T-shaped guide groove 34 at the top, which restricts the vertical offset of the mounting base 33 and only allows it to move horizontally along the T-shaped guide rail 31. The welding gun 35 is fixed on the side of the mounting base 33 away from the second cylinder 32 and moves synchronously with the mounting base 33.

[0050] Furthermore, through the drive of the second cylinder 32, which is driven by the existing pneumatic control system, and the guidance of the T-shaped guide rail 31 and the T-shaped guide groove 34, the horizontal position of the welding gun 35 can be precisely adjusted, so that the welding gun 35 can be adapted to the weld position of flanges of different specifications.

[0051] like Figure 1 - Figure 3 As shown, the adjustable welding roller frame 2 is fixedly connected to the top of the base 1 in a horizontal array;

[0052] The adjustable welding roller frame 2 is fixed on the top of the base 1 in a horizontal array. The rollers can adjust the spacing according to the diameter of the tower column and fit the outer wall of the column. When the rollers rotate, the column rotates synchronously through friction. The adjustment and driving of the adjustable welding roller frame 2 are existing technologies and will not be described in detail here.

[0053] The working principle of the straight column welding device for the iron tower is as follows:

[0054] Place the tower column on the adjustable welding roller frame 2 at the top of the base 1, ensuring that both ends of the tower column are positioned between adjacent adjustable welding roller frames 2. Then, activate the hydraulic cylinder 16 to drive the output end to push the connecting plate 18 downwards. The first guide rod 19 at the top of the connecting plate 18 will move along the first guide hole 15 at the top of the movable plate 11. The connecting plate 18 will then drive the lifting plate 17 downwards until the rotating disk 22 on one side of the lifting plate 17 is at the same horizontal position as the tower column. Then, use bolts and nuts to fix the flange seat 24, which is compatible with the flange, to the rotating shaft 23. Next, install the flange onto the flange seat 24. During installation, insert the pin 25 on one side of the flange seat 24 into the flange hole on the flange seat 24 to complete the flange installation. After positioning, the drive motor 9 installed on one side of the crossbeam 4 is turned on. The drive motor 9 drives the rotating rods 8 at both ends of the double-acting screw 7 through the coupling to rotate within the rotating holes 6 on one side of the crossbeam 4. The rotating rods 8 drive the double-acting screw 7 to rotate within the protective shell 5. At the same time, the two connecting seats 12 installed at the bottom of the two movable plates 11 will move along the limit sliding rod 10 installed between the double-acting screw 7 and the crossbeam 4 on one side through the sliding holes 13 and screw holes 14 on one side, respectively. The movable plates 11 will move relative to each other, and drive the flange installed on the flange seat 24 below to move synchronously until the flange is tightly against both ends of the tower column. Then, the second cylinder 32 drives the drive output end towards the mounting seat 33, so that the mounting seat... The welding gun 35, mounted on the side of the mounting base 33, slides along the T-shaped guide rail 31 through the T-shaped guide groove 34 at the top until it moves to the welding position between the flange and the end of the tower column. Then, the first cylinder 28 drives the output end to push the L-shaped plate 29 downward. The second guide rod 30 at the top of the L-shaped plate 29 moves along the second guide hole 27 at the top of the fixing plate 26 until the welding gun 35 moves down and approaches the welding position. Then, the welding is performed on the mating surface between the tower column and the flange. Then, during the welding process, the adjustable welding roller frame 2 is opened. The adjustable welding roller frame 2 drives the tower column to rotate slowly. When rotating, it drives the rotating disk 22 to rotate. The rotating shaft 23 on the other side of the rotating disk 22 will be installed in the mounting hole on the side of the lifting plate 17. The bearing 21 installed inside the 20 rotates to achieve synchronous rotation of the tower column and flange. During the rotation, the welding gun 35 performs circumferential welding on the tower column and flange. After welding, the two lifting plates 17 are controlled to move in opposite directions to disengage the flange seat 24 from the flange. Then, the lifting plates 17 are moved upward. Finally, the tower column with flanges welded to both ends is removed, and preparation is made for the next welding operation. Furthermore, the adjustable welding roller frame 2 allows for rotational operation when welding tower columns of different diameters and lengths. The detachable flange seat 24 allows for the installation of flanges of different diameters. The distance and height between the flange seats 24 can be controlled and adjusted to achieve the connection between tower columns of different diameters and lengths and flanges.By adjusting the lateral position and height of the welding gun 35, the flange can be effectively welded to both ends of the straight column of the iron tower.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
