Description

Technical Field

[0001] This invention relates to the field of ultra-high voltage steel pipe tower processing technology, specifically to a mobile device for welding steel pipes in ultra-high voltage steel pipe towers. Background Technology

[0002] At the steel pipe tower installation site, steel pipes need to be welded together. However, when unloaded from the transport vehicle, the steel pipes are usually placed side by side. Before welding, these steel pipes to be welded need to be moved to the welding point or a convenient welding location. The existing common methods are to use forklifts or manual labor for handling. Using forklifts for handling is costly, difficult to operate, easily restricted by the site environment, and inconvenient to move. Handling steel pipes entirely by manual labor consumes a lot of manpower, has low construction efficiency, high construction risk, and is inconvenient to operate, which causes many inconveniences to the relevant construction procedures.

[0003] For example, in the existing Chinese patent, publication (announcement) number: CN110550318A, although a steel pipe mobile trolley is used to achieve a labor-saving transportation method, the structure of the jack and bearing rod passing through the connecting pipe and fixed by bolts still requires manual operation, resulting in low on-site welding and installation efficiency and requiring more personnel to participate.

[0004] Therefore, a mobile device for welding steel pipes of ultra-high voltage steel pipe towers is needed. Summary of the Invention

Gear 1 is meshed between toothed plate 1 and toothed plate 2. Gear 1 is connected to servo motor 1 through a rotating shaft. Servo motor 1 is fixedly connected to fixed plate 2. Positioning rails are symmetrically arranged at the bottom of fixed plate 2. The positioning rails are symmetrically arranged with respect to the center line of slot 1. Both sides of clamping plate component 1 and clamping plate component 2 are connected to the positioning rails. Arc-shaped clamping plate components are arranged on the bottom surfaces of clamping plate component 1 and clamping plate component 2.

[0007] Preferably, the clamping plate assembly two is arranged in an "L" shaped plate shape, and the upper part of the clamping plate assembly two is provided as a toothed plate three. The upper part of the toothed plate three is meshed with at least two sets of gear seat assemblies. The gear seat assembly includes a fixed base and a rolling gear. The fixed base is fixedly connected to the bottom of the fixed plate one, and the bottom shaft of the fixed base is rotatably connected to the rolling gear. The rolling gear is meshed with the toothed plate three.

[0008] Preferably, the arc-shaped clamping plate assembly includes a fixed clamping plate and an adjustable clamping plate. The clamping plate assembly one is arranged in an "L" shape. The fixed clamping plate is fixedly connected to the bottom of both the clamping plate assembly one and the clamping plate assembly two, and the adjustable mounting clamping plate is fixedly connected to the top. The bottom surfaces of the clamping plate assembly one and the clamping plate assembly two are opened with at least two mounting holes. The back of the adjustable clamping plate is fixedly connected to a drive plate one that passes through the mounting holes. The bottom surface of the drive plate one that passes through the mounting holes is fixedly connected to a telescopic rod two. The fixed rod of the telescopic rod two is fixedly connected to a support plate one. The support plate one is fixedly connected to the clamping plate assembly one and the clamping plate assembly two respectively.

[0009] Preferably, the mounting hole is symmetrically connected to a slide rail, and the protrusions on both sides of the drive plate are slidably connected to the inside of the slide rail. The protrusions are slidably connected to the slide rail to ensure that the displacement guidance adjustment of the adjustment clamp is stable.

[0010] Preferably, the transportation platform assembly includes a platform plate one and a fixed plate three. The upper part of the platform plate one is equipped with a UPS power supply box and an intelligent control box. The four bottom corners of the platform plate one are connected to the fixed plate three by fixing rods. The bottom of the fixed plate three is equipped with electric wheel assemblies.

[0011] Preferably, the electric wheel assembly includes an active drive wheel and a secondary drive wheel, with the active drive wheel mounted on the bottom of the two fixed plates on the same side and the secondary drive wheel mounted on the other side.

[0014] By adjusting the adjustable structure of the clamping plates and coordinating the movement of clamping plate assembly one and clamping plate assembly two, which can move away from or closer to each other, the steel pipes of different diameters in the steel pipe tower can be transported.

[0016] The invention will now be further described with reference to the accompanying drawings.

[0017] like Figures 1 to 4 As shown: To achieve a labor-saving method for handling and welding steel pipes in ultra-high voltage steel pipe towers, and to eliminate the need for manpower in loading and unloading operations, this invention provides a mobile device for welding steel pipes in ultra-high voltage steel pipe towers. The components used are as follows: the electric wheel assembly adopts the domestic heavy-duty vertical steering wheel from Yikongtec; the first telescopic rod adopts the DC multi-section push rod from Zhejiang Chemming Transmission Technology Co., Ltd.; the second telescopic rod adopts the 12V / 24V DC industrial-grade electric push rod; the core configuration of the intelligent control box adopts the AB433L + S7 series PLC; and the UPS power supply box preferably adopts an online UPS with a capacity of 2000VA or above to ensure stable and uninterrupted power support for the wireless control system in complex industrial environments.

[0018] like Figures 2 to 3 As shown: The technical solution of this invention includes a transport platform assembly 1. An electric wheel assembly 2 is installed at the bottom of the transport platform assembly 1 to drive its movement. A telescopic rod 3 is symmetrically fixedly connected to the upper part of the transport platform assembly 1. The drive rod of the telescopic rod 3 passes through the transport platform assembly 1 and is fixedly connected to a fixed plate 4. Fixed plates 5 are fixedly connected to the four corners of the bottom of the fixed plate 4 via connecting rods. A slot 6 is symmetrically opened in the middle of the fixed plate 5. Clamping plate assemblies 7 and 8 are installed in the slots 6 on both sides, with the clamping plate assemblies 8 positioned above the clamping plate assemblies 7. The upper part of clamping plate assembly 7 is provided with toothed plate 9, and the lower part of clamping plate assembly 8 is provided with toothed plate 10. Gear 11 is meshed between toothed plate 9 and toothed plate 10. Gear 11 is connected to servo motor 12 through a rotating shaft. Servo motor 12 is fixedly connected to fixed plate 5. Positioning rails 13 are symmetrically arranged at the bottom of fixed plate 5. Positioning rails 13 are symmetrically arranged with respect to the center line of slot 6. Both sides of clamping plate assembly 7 and clamping plate assembly 8 are connected to positioning rails 13. Arc-shaped clamping plate assemblies 14 are provided on the bottom surfaces of clamping plate assembly 7 and clamping plate assembly 8.

[0019] Specifically: the transport platform component 1 moves to the steel pipe of the steel pipe tower waiting to be transported via the electric wheel component 2. The telescopic rod 3 extends and retracts, causing the fixed plate 4 and fixed plate 5 to move downwards. When the clamping plate component 7 and clamping plate component 2 are placed on both sides of the steel pipe of the steel pipe tower, the servo motor 12 drives the gear 11 to rotate. The gear 11 meshes between the toothed plate 9 and the toothed plate 10. The gear 11 drives the clamping plate component 7 and clamping plate component 2 to move in opposite directions. Slider 1 is distributed on both sides of the lower part of the clamping plate component 7 and clamping plate component 2. The slider 1 is slidably connected to the positioning rail 13. The guide clamping plate assembly 7 and clamping plate assembly 8 slide in the same direction as the steel pipe tower, and provide support for the steel pipes during transport. The plate assembly 7 and clamping plate assembly 8 slide in contact with the fixed plate 25 to provide support and load-bearing function during the transport of the steel pipe tower. An arc-shaped clamping plate assembly 14 is provided on the opposite side of the guide clamping plate assembly 7 and clamping plate assembly 28. The servo motor 12 drives the clamping plate assembly 7 and clamping plate assembly 28 to move and adjust, thereby supporting and fixing the steel pipes of the steel pipe tower. The telescopic rod 13 extends and lifts the steel pipes of the steel pipe tower. The electric wheel assembly 2 is controlled to transport the steel pipes of the steel pipe tower to the welding construction site for welding. The technical solution of this patent enables automated control and adaptable clamping and transportation of steel pipe towers with different diameters, eliminating the need for manual intervention before clamping and transportation and at the construction site, thereby improving the handling efficiency of steel pipe towers and steel pipes.

[0020] like Figure 3 As shown: In at least one embodiment, the clamping plate assembly 2 8 is arranged in an "L" shaped plate shape, and the upper part of the clamping plate assembly 2 8 is provided as a toothed plate 3 15. The upper part of the toothed plate 3 15 is meshed with at least two sets of gear seat assemblies. The gear seat assembly includes a fixed base 16 and a rolling gear 17. The fixed base 16 is fixedly connected to the bottom of the fixed plate 1 4, and the bottom shaft of the fixed base 16 is rotatably connected to the rolling gear 17. The rolling gear 17 is meshed with the toothed plate 3 15.

[0021] Specifically, to further improve the adjustment stability of the clamping plate assembly two and its load-bearing support function for the steel pipes of the steel pipe tower, the clamping plate assembly two is rotated and meshes with gear 11 at its bottom and with rolling gear 17 at its top. This allows the clamping plate assembly two to be slidably adjusted between the two rolling gears 17 and gear 11, enabling directional sliding of the clamping plate assembly two. The two rolling gears 17 and gear 11 also provide meshing support for the clamping plate assembly two, improving its load-bearing support for the steel pipes of the steel pipe tower, enhancing the heavy-load capacity of the transportation equipment, and increasing transportation efficiency.

[0022] like Figure 4As shown: In at least one embodiment, the arc-shaped clamping plate assembly 14 includes a fixed clamping plate 21 and an adjustable clamping plate 22. The clamping plate assembly 7 is arranged in an "L" shape. The fixed clamping plate 21 is fixedly connected to the bottom of the clamping plate assembly 7 and the adjustable clamping plate 22 at the top. The bottom surfaces of the clamping plate assembly 7 and the clamping plate assembly 8 are provided with at least two mounting holes 23. The back of the adjustable clamping plate 22 is fixedly connected to a drive plate 36 that passes through the mounting hole 23. The drive plate 36 passes through the bottom surface of the mounting hole 23 and is fixedly connected to a telescopic rod 24. The fixed rod of the telescopic rod 24 is fixedly connected to a support plate 25. The support plate 25 is fixedly connected to the clamping plate assembly 7 and the clamping plate assembly 8 respectively.

[0023] Specifically, by adjusting the adjustable structure of the clamping plate 22 and coordinating the displacement adjustment of clamping plate assembly 7 and clamping plate assembly 8 to move away from or towards each other, the steel pipes of different diameters in the steel pipe tower can be transported. The clamping plate assembly 7 and clamping plate assembly 8 distributed on both sides are moved by the servo motor 12 to adapt to the diameter of the steel pipes in the steel pipe tower. As the clamping plate assembly 7 and clamping plate assembly 8 move closer to the steel pipes in the steel pipe tower, the clamping plate 22 is adjusted upward or downward by the lifting action of the telescopic rod 24. After the fixed clamping plate 21 at the bottom clamps and fits with the steel pipes in the steel pipe tower, the telescopic rod 24 drives the adjusting clamping plate 22 to clamp and fit with the steel pipes in the steel pipe tower. The fixed plate 4 is lifted by the telescopic rod 3, so that the steel pipes in the steel pipe tower are lifted off the ground for transportation. The steel pipes in the steel pipe tower are transported to the construction site by controlling the rotation of the electric wheel assembly 2.

[0024] like Figure 4 As shown: In at least one embodiment, in order to achieve stable adjustment and movement of the adjusting clamp 22 and stable clamping and transportation of steel pipes in steel pipe towers, a slide rail 26 is symmetrically connected to the outside of the mounting hole 23. The protrusions connected to both sides of the drive plate 36 are slidably connected to the inside of the slide rail 26. The protrusions are slidably connected to the slide rail 26 to ensure stable displacement guidance of the adjusting clamp 22, so as to achieve smooth lifting and lowering adjustment of the adjusting clamp 22 to adapt to the clamping and transportation of steel pipes in steel pipe towers of different diameters.

[0025] like Figure 2 As shown: In at least one embodiment, the transportation platform assembly 1 includes a platform plate 27 and a fixed plate 31. The upper part of the platform plate 27 is provided with a UPS power box 32 and an intelligent control box 33. The four corners of the bottom of the platform plate 27 are connected to the fixed plate 31 by fixing rods. The bottom of the fixed plate 31 is provided with an electric wheel assembly 2.

[0026] Specifically, the UPS power box 32 provides power to the transport device, such as connecting the intelligent control box 33, telescopic pole 3, servo motor 12, telescopic pole 24 and electric wheel assembly 2 via wires. The intelligent control box 33 controls the operation of the telescopic pole 3, servo motor 12, telescopic pole 24 and electric wheel assembly 2. The intelligent control box 33 has a built-in AB433L wireless Ethernet transmission module, which can wirelessly control the clamping steel pipe of the transport device and the transport steel pipe of the steel pipe tower.

[0027] like Figure 2 As shown: In at least one embodiment, the electric wheel assembly 2 includes an active drive wheel 34 and a secondary drive wheel 35, with the active drive wheel 34 mounted on the bottom of the same side of the two fixed plates 31 and the secondary drive wheel 35 mounted on the other side.

[0028] Specifically, the active drive wheel 34 drives the movement of the transport device, while the secondary drive wheel 35 serves as an auxiliary rolling support and a backup drive wheel, thereby improving the long-term durability of the electric wheel assembly 2, reducing the frequency of failure and maintenance of the electric wheel assembly 2, and improving the efficiency of transportation.

[0029] In at least one embodiment, in order to achieve stable meshing drive between gear 11 and clamping plate assembly 7 and clamping plate assembly 8, and stable rotational connection between gear 11 and servo motor 12, a rotating shaft is rotatably connected between gear 11 and servo motor 12, and the rotating shaft is connected to fixed plate 2 5 through fixed base 16.

Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the scope of protection of this invention.
