[0031] The first clamping seat 104 includes a clamping seat body 111, two clamping plates 112, a clamping cylinder 113 and a triangular push block 114. The two clamping plates 112 are rotatably arranged on both sides of the clamping seat body 111, and the triangular push block 114 is slidably arranged between the control rods of the two clamping plates 112.

Two clamping plates 112 are respectively arranged on both sides of the clamping seat body 111 and can rotate around their respective axes to clamp the steel pipe. The output end of the clamping cylinder 113 is fixedly connected to the triangular push block 114. When the clamping cylinder 113 is actuated, it pushes the triangular push block 114 to move. The triangular push block 114 is slidably arranged between the control rods of the two clamping plates 112.

[0036] Push rod 118 is fixedly connected to the output end of second cylinder 120 for force transmission. Contact plate 119 is rotatably connected to push rod 118 for direct contact with the steel pipe. The action of second cylinder 120 can lift the sliding rod 106 through the reaction force after contact with the steel pipe, thereby lifting the first clamping seat 104 and other structures below, thereby facilitating passage through the connected steel pipe rack.

[0037] The first positioning seat includes a positioning seat body 121, a fixing bolt 122, a positioning plate 123 and an adjusting cylinder 124.

[0039] The first positioning seat and the second positioning seat further have a top limiting rod 125, and the two top limiting rods 125 cooperate to limit the top steel pipe.

[0040] The two top limiting rods 125 are respectively arranged on the first positioning seat and the second positioning seat, and act together on the top steel pipe to be welded to prevent the steel pipe from deflecting during the welding process.

[0041] The first positioning seat further includes a return spring 126 , which is disposed between the positioning plate 123 and the regulating cylinder 124 .

[0046] Second embodiment

[0047] See also Figure 5 The present invention also provides a high-strength steel pipe tower welding process, comprising:

[0048] S201: Fix the first clamping seat 104 to the bottom steel pipe and align the mounting platform 110 with the top of the steel pipe;

[0049] First, the first clamping seat 104 is fixed to the bottom steel pipe to ensure that the clamping seat can firmly clamp the steel pipe. Then, the mounting platform 110 is adjusted to a position aligned with the top of the bottom steel pipe to ensure that subsequent positioning and welding operations can be carried out accurately.

[0050] S202: placing the steel pipes to be welded on the first positioning seat and the second positioning seat respectively for positioning;

[0051] The steel pipes to be welded are placed on the first and second positioning seats. The positions of the steel pipes are adjusted using the positioning plates 123 and adjustment cylinders 124 on the positioning seats to ensure that the steel pipes are accurately positioned in the predetermined position. This step ensures precise alignment between the steel pipes and is the key to welding quality.

[0052] After S203 positioning is completed, the two steel pipes are welded and the top steel pipe is welded;

[0053] After the steel pipes are correctly positioned, welding begins. First, the joint between the two pipes is welded, followed by the joint between the top pipe and the lower pipe. This process requires a high level of skill from the welding operator to ensure weld quality and structural stability.

[0054] After the welding is completed in step S204, the first control cylinder 105 is activated to drive the second clamping seat 108 to rise and connect with the top steel pipe, and then disconnect the first clamping seat 104 from the bottom steel pipe;

[0055] After welding is completed, the first control cylinder 105 is activated, causing the sliding rod 106 to drive the rotating rod 107 and the second clamping seat 108 to rise. The second clamping seat 108 rises until it contacts and connects the top steel pipe. Then, the first clamping seat 104 is separated from the bottom steel pipe, preparing for the next operation.

[0056] S205: When the first control cylinder 105 contracts, it drives the first clamping seat 104 to rise, and rotates the rotating rod 107 so that the first clamping seat 104 can pass around the welded steel pipe;

[0057] The first control cylinder 105 continues to move, shrinking and driving the first clamping seat 104 to lift. At this time, the rotating rod 107 is rotated to make the first clamping seat 104 bypass the welded steel pipe to leave space for the next operation.

[0058] S206: Adjust the position of the first clamping seat 104 so that the mounting platform 110 is aligned with the top of the steel pipe again so that welding can be performed again.

[0059] After the first clamping seat 104 passes around the welded steel pipe, adjust its position so that the mounting platform 110 is aligned with the top steel pipe. At this point, you can repeat the above steps to weld the next section of steel pipe until all steel pipes are correctly connected.

[0060] Through the above steps, the welding process of high-strength steel pipe towers can be completed efficiently and accurately. This process not only improves welding efficiency but also ensures welding quality, making it suitable for large-scale production.

[0061] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of the rights of the present invention.
