[0002] High-frequency welded pipe is a steel pipe manufacturing process that uses the skin effect and proximity effect of high-frequency current for welding. This welding method heats the welding area of the steel pipe through the resistance heat generated by high-frequency current, causing local melting of the metal, and realizing the connection between metals under the application of pressure. After retrieval, the patent with the authorization number of CN220575969U in China discloses a clamping device for high-frequency welded pipes, including a hollow column and a clamping mechanism installed on one side of the hollow column. The clamping mechanism includes a braking component and a clamping component. The braking component includes a first support plate, a hydraulic rod, a first slider, a first slide rail, and a first fixing plate. A first support plate is installed on one side of the hollow column, and a hydraulic rod is installed on the top side of the first support plate; this clamping device for high-frequency welded pipes is provided with a hydraulic rod. Through the telescopic movement of the hydraulic rod, the first slider can be driven to slide on the first slide rail. After a series of transmission effects, finally, two U-shaped plates will form a clamping effect. And the U-shaped plates can be replaced through threaded nails, and different U-shaped plates can clamp pipes of different thicknesses, avoiding the situation that transporting pipes is often done manually or manually moving the pipes onto mobile tools, which is time-consuming and laborious, and there will also be a series of dangers for heavier pipes.

[0024] Refer to Figures 1 - 5, A clamping device for high-frequency welded pipes, including a moving table 1. At the rear end of the top of the moving table 1, a vertical frame 2 is fixedly connected. Inside the vertical frame 2, a lifting plate 204 is slidably connected. At the front end of the bottom of the lifting plate 204, a T-shaped block 302 is fixedly connected. At both ends of the T-shaped block 302, rotating rods 303 are slidably sleeved. At both ends of the T-shaped block 302, round holes adapted to the rotating rods 303 are opened. At the front ends of both rotating rods 303, L-shaped rods 305 are fixedly connected. At the front ends of both L-shaped rods 305, rotating plates 4 are fixedly connected. On the side where the bottoms of both rotating plates 4 are close to each other, a clamping mechanism 5 is provided. The clamping mechanism 5 includes a U-shaped plate 503 fixedly connected to the inner side of the bottom of the rotating plate 4. Between the two ends of the inner side of the U-shaped plate 503, two limiting rods 504 are fixedly connected. At the same end of both limiting rods 504, the same sliding plate 505 is slidably sleeved. On both sliding plates 505, two round holes adapted to the limiting rods 504 are opened. On the tops of both sliding plates 505, first inclined holes 506 are opened. On the sides of both sliding plates 505 away from the rotating plate 4, arc-shaped clamping plates 507 are fixedly connected by bolts. At the bottom of both rotating plates 4, strip-shaped holes 401 are opened. The clamping mechanism 5 further includes a moving plate 508 slidably connected in the strip-shaped hole 401. Between the top and the bottom of the strip-shaped hole 401, the same round rod 509 is fixedly connected. The round rod 509 slidably penetrates through the moving plate 508. On the moving plate 508, a round hole adapted to the round rod 509 is opened. At the position where the round rod 509 is located at the top of the moving plate 508, a spring 510 is sleeved.

[0025] In this embodiment, the clamping mechanism 5 further includes a cross bar 511 fixedly connected to the inner bottom of the moving plate 508. At both ends of the cross bar 511 close to the first inclined hole 506, convex blocks 512 are fixedly connected.

At the end of the moving plate 508 away from the arc-shaped clamping plate 507, a pull rod 501 is fixedly connected. At the top of the pull rod 501, a pull hole 502 is opened.

[0026] In this embodiment, at the front end of the top of the lifting plate 204, a first L-shaped plate 6 is fixedly connected. At the front end of the first L-shaped plate 6, a U-shaped block 7 is fixedly connected. At both ends of the inner side of the U-shaped block 7, T-shaped grooves 701 are opened. In both T-shaped grooves 701, T-shaped sliders 9 are slidably connected. Between the two T-shaped sliders 9, the same square rod 901 is fixedly connected. At both ends of the square rod 901, rectangular blocks 10 are slidably sleeved. On the tops of both rectangular blocks 10, square holes adapted to the square rod 901 are opened. At the ends of the bottoms of both rectangular blocks 10 away from each other, inserting rods 12 are fixedly connected. On both rectangular blocks 10, second inclined holes 11 are opened. Both inserting rods 12 are adapted to the pull hole 502.

[0027] In this embodiment, a second L-shaped plate 8 is fixedly connected to the top of the U-shaped block 7. An electric push rod 801 is fixedly connected to the bottom of the second L-shaped plate 8. Two cross bars 802 are fixedly connected to the bottom of the electric push rod 801. Sliding rods 803 are fixedly connected to both ends of the cross bars 802. The two sliding rods 803 are respectively slidably connected in the adjacent second inclined holes 11. The settings of the T-shaped groove 701 and the T-shaped slider 9 enable the two insertion rods 12 to first insert into the pulling holes 502 and then approach each other when the electric push rod 801 extends.

[0028] In this embodiment, a reduction motor 3 is fixedly connected to the top of the lifting plate 204. The output end of the bottom of the reduction motor 3 penetrates through the lifting plate 204 and is fixedly connected to a worm 301. Worms 304 are fixedly connected to the rear ends of the two rotating rods 303. The two worms 304 are both engaged with the worm 301. The one-way transmission property of the worms 304 and the worm 301 enables the two rotating plates 4 to be in a horizontal state after being unfolded, which is more stable.

[0029] In this embodiment, the same sliding rod 201 is fixedly connected between the top and the bottom of the inner side of the vertical frame 2. The sliding rod 201 slidably penetrates through the lifting plate 204. A round hole adapted to the sliding rod 201 is formed in the lifting plate 204.

[0030] In this embodiment, the same lead screw 202 is rotatably connected between the top and the bottom of the inner side of the vertical frame 2. The lead screw 202 threadedly penetrates through the lifting plate 204. A threaded hole adapted to the lead screw 202 is formed in the lifting plate 204. A driving motor 203 is fixedly connected to the top of the vertical frame 2. The output end of the bottom of the driving motor 203 penetrates through the vertical frame 2 and is fixedly connected to the top of the lead screw 202.

[0031] Working principle: When in use, move it to the working place, start the reduction motor 3 to drive the worm 301 to rotate. Through the arrangement of two worm wheels 304, the two rotating rods 303 drive the L-shaped rod 305 and the rotating plate 4 to rotate in the reverse direction until the two rotating plates 4 are in a horizontal state. Then start the driving motor 203. By controlling the forward and reverse rotation of the driving motor 203, the lifting plate 204 drives the two clamping mechanisms 5 to descend to the position of the welded pipe. In the natural state, due to the arrangement of the two springs 510, the two arc-shaped clamping plates 507 of the clamping mechanisms 5 on both sides are in an open state. When the two arc-shaped clamping plates 507 on both sides are located on both sides of the welded pipe, start the electric push rod 801 to extend. At the initial stage of extension, due to the action of gravity, the T-shaped slider 9 and the square rod 901 drive the two rectangular blocks 10 to descend along the T-shaped groove 701, so that the two inserting rods 12 are inserted into the corresponding pulling holes 502. The electric push rod 801 continues to extend, so that under the action of the second inclined hole 11, the two inserting rods 12 approach each other, and the two pull rods 501 approach each other. Through the arrangement of the pull rod 501, the moving plate 508 and the cross bar 511, the convex block 512 slides in the first inclined hole 506, so that the two arc-shaped clamping plates 507 of the clamping mechanism 5 approach each other to realize the clamping and fixing of the welded pipe. By starting the driving motor 203, the lifting and moving of the welded pipe are realized. The arrangement of the two clamping mechanisms 5 makes the fixing of the welded pipe more stable.
