[0031] Embodiment 1

[0032] See also Figure 1-Figure 5 As shown in the figure, a steel pipe cross arm welding clamping device includes a device body 100 and a first clamp 200, and a second clamp 300 is installed on the side of the device body 100;

[0033] A support assembly 500 is provided on the side of the first clamp 200. The support assembly 500 includes a gas chamber 501 and a torsion spring rod 504. An air bag 502 is fixedly connected to one end of the gas chamber 501, and a clamp rod 503 is slidably connected to the other end of the gas chamber 501. The steel pipe rod is placed between the first clamp 200 and the second clamp 300, and the position of the first clamp 200 is adjusted. When the steel pipe rod squeezes the air bag 502 on the first clamp 200, the gas in the air bag 502 is passed into the gas chamber 501 fixedly connected thereto, so that the pressure in the gas chamber 501 increases, driving the clamp rod 503 slidably connected to the gas chamber 501 to move. A slot 505 is provided at the top of the torsion spring rod 504, and the slot 505 is located at the bottom of the rod 503. The cross-sectional shape of the slot 505 matches the rod 503. A support plate 506 is fixedly connected to the side of the torsion spring rod 504. Two support plates 506 are provided, and the two support plates 506 are symmetrically distributed about the air pressure chamber 501. A friction rubber pad 507 is fixedly connected to the support plate 506. When the rod 503 moves and moves out of the slot 505, the torsion spring rod 504 loses its restriction, and the support plate 506 fixedly connected thereto is driven to rotate under its own action, so as to support the steel pipe rod and automatically complete the preliminary clamping of the steel pipe rod. At this time, the first clamp 200 is clamped on the steel pipe rod through the support assembly 500, and then the first clamp 200 and the second clamp 300 can be installed by bolts, making the whole process more convenient.

[0034] When in use, the steel tube rod is placed between the first clamp 200 and the second clamp 300, and the position of the first clamp 200 is adjusted. When the steel tube rod squeezes the airbag 502 on the first clamp 200, the gas in the airbag 502 is passed into the air pressure chamber 501 fixedly connected thereto, so that the pressure in the air pressure chamber 501 increases, driving the clamping rod 503 slidingly connected to the air pressure chamber 501 to move, and the clamping rod 503 is immediately moved out of the clamping groove 505, so that the torsion spring rod 504 loses its restriction, and under its own action, drives the support plate 506 fixedly connected thereto to rotate, thereby completing the support of the steel tube rod.

[0035] To adjust the distance between the two clamps in multiple stages, see Figure 1-Figure 5As shown in the figure, an adjustment assembly 400 is arranged between the first clamp 200 and the second clamp 300. The adjustment assembly 400 includes a fixing plate 401. An arc groove 402 is provided on the first clamp 200. A transmission rod 403 is slidably connected inside the arc groove 402. The side of the transmission rod 403 is fixed to the support assembly 500. When fixing steel pipe rods with different inner diameters, the first clamp 200 is moved toward the steel pipe rod, and the transmission rod 403 on the first clamp 200 moves toward the steel pipe rod. The steel pipe rod squeezes the support assembly 500. Since the transmission rod 403 is slidably connected to the arc groove 402, the support assembly 500 drives the transmission rod 403 fixedly connected thereto to move sideways. A spring 1 405 is fixedly connected to the side of the transmission rod 403, a limiting groove 406 is provided on the side of the transmission rod 403, and a clamping block 408 is connected to the side of the fixed plate 401 via a spring 2 407. The side of the clamping block 408 is arc-shaped, and the cross-sectional shape of the clamping block 408 is adapted to the limiting groove 406. When the support assembly 500 drives the transmission rod 403 fixedly connected thereto to move sideways, during the movement, the transmission rod 403 squeezes the block 408, so that the block 408 squeezes the spring 2 407 fixedly connected thereto and moves toward the fixed plate 401. When the transmission rod 403 moves to the block 408 with the limiting groove 406 thereon, the block 408 loses its restriction and moves into the limiting groove 406 under the action of the spring 2 407 to be clamped. Because the block 408 is arc-shaped on one side close to the first clamp 200, the block 408 can limit the transmission rod 403 so that it can only move to the left but not to the right. In this way, the distance between the support assembly 500 and the second clamp 300 can be adjusted in turn to adapt to the steel pipe rod with the corresponding inner diameter, so that the device can perform corresponding clamping operations on the steel pipe rods with different inner diameters, reducing the possibility of affecting subsequent welding operations. The top of the first clamp 200 is fixedly connected with a hydraulic bin 409, one end of which is slidably connected with a round rod 410, which is located at the side of the block 408, and is fixed between the round rod 410 and the block 408, and the other end of the hydraulic bin 409 is slidably connected with an operating handle 411. After welding is completed, when it needs to be disassembled, the operating handle 411 is moved upward to cooperate with the hydraulic bin 409 slidably connected to the operating handle 411, so that the pressure in the hydraulic bin 409 is reduced, and the round rod 410 slidably connected to the hydraulic bin 409 is driven to move, and the round rod 410 then drives the block 408 fixedly connected thereto to move away from the limiting groove 406, and the restriction is released, so that the welded object can be taken out for subsequent operations.

[0036] When in use, when fixing steel pipe rods with different inner diameters, the first clamp 200 is moved toward the steel pipe rod, and the transmission rod 403 on the first clamp 200 moves toward the steel pipe rod, and the steel pipe rod squeezes the support assembly 500. Since the transmission rod 403 is slidably connected with the arc groove 402, the support assembly 500 drives the transmission rod 403 fixedly connected thereto to move sideways. During the movement, the transmission rod 403 squeezes the block 408, so that the block 408 squeezes the spring 2 407 fixedly connected thereto and moves toward the fixed plate 401. When the transmission rod 403 moves to the block 408 with the limiting groove 406 thereon, the block 408 loses its restriction and moves to the limiting groove 406 under the action of the spring 2 407. 06, clamp it, and because the side of the clamping block 408 close to the first clamping hoop 200 is arc-shaped, the clamping block 408 can limit the transmission rod 403, so that it can only move to the left and cannot move to the right, so that the distance between the support assembly 500 and the second clamping hoop 300 can be adjusted in turn to adapt to the steel pipe rod of the corresponding inner diameter; after welding is completed, when it needs to be disassembled, the operating handle 411 is moved upward, cooperating with the hydraulic warehouse 409 slidably connected to the operating handle 411, so that the pressure in the hydraulic warehouse 409 is reduced, driving the round rod 410 slidably connected to the hydraulic warehouse 409 to move, and the round rod 410 then drives the clamping block 408 fixedly connected to it to move away from the limit groove 406, thereby releasing the restriction.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
