Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1, given by Figures 1-4 The present utility model relates to a support device for steel pipe welding, including two support tables 1. A moving groove 2 is opened at the top of the support table 1, and a support assembly 3 is installed above the support table 1;

[0025] The support assembly 3 includes two support rollers 303 symmetrically arranged above the support table 1. Below the support rollers 303, there is an installation table 301. Between the two installation tables 301, there is a pressing assembly 4. At the bottom end of the installation table 301, a moving seat 305 is installed. The moving seats 305 at the bottom ends of the two installation tables 301 are both slidably installed inside the moving groove 2. Inside the moving groove 2, a double-headed screw 306 is rotatably installed. The two moving seats 305 are respectively threadedly connected to two threaded grooves with opposite opening directions on the double-headed screw 306. One end of the double-headed screw 306 is fixedly connected to the output shaft of the second motor 307. The second motor 307 is fixedly installed on the support table 1. At the top end of the installation table 301, side plates 302 are symmetrically installed. The two ends of the support roller 303 are respectively rotatably connected to the two side plates 302. One end of the support roller 303 is fixedly connected to the output shaft of the first motor 304. The first motor 304 is fixedly installed on the side plate 302. Above the support table 1, two support rollers 303 are provided. When the two support rollers 303 approach each other, a support space can be formed between the two support rollers 303. The two support rollers 303 support the steel pipe, facilitating the support of steel pipes with different diameters. At the same time, the support rollers 303 can rotate, facilitating the rotational adjustment of the steel pipe.

[0026] The pressing assembly 4 includes a sliding groove 401 opened on the installation table 301. At one end of the installation table 301, an installation frame 402 is installed. The installation frame 402 is located at one end of the installation tables 301 on the two support tables 1 that are far away from each other. On the installation frame 402, a cylinder 403 is installed. The output end of the cylinder 403 is located inside the sliding groove 401. Between the two installation tables 301, there is a push plate 405. At the bottom end of the push plate 405, a sliding plate 404 is fixedly installed. The two ends of the sliding plate 404 are located inside the sliding groove 401. At the two ends of the sliding plate 404, limit plates 406 are symmetrically installed. The two limit plates 406 are respectively located on the sides of the two installation tables 301 that are far away from each other. At the top end of the sliding plate 404, contact blocks 408 are symmetrically provided. On the side of the contact block 408 close to the push plate 405, a spring 409 is installed. One end of the spring 409 is fixedly connected to the side wall of the push plate 405. The other side of the contact block 408 contacts the side wall of the installation table 301. The contact block 408 is slidably installed on the sliding groove 407. The sliding grooves 407 are symmetrically opened at the top end of the sliding plate 404. Between the two installation tables 301, a push plate 405 is provided. The two push plates 405 are respectively arranged on the sides of the two steel pipes that are far away from each other. The two push plates 405 approach each other, pushing the two steel pipes closer to each other until the close ends of the two steel pipes are in close contact, facilitating the fixation of the steel pipes and improving the welding effect. On both sides of the push plate 405, springs 409 are symmetrically provided. The contact blocks 408 at the ends of the springs 409 contact the side wall of the installation table 301. When the two support rollers 303 approach each other, under the action of the springs 409 on both sides, the push plate 405 is located on the axis of symmetry of the two support rollers 303, enabling the push plate 405 to keep the position corresponding to the steel pipe.

[0027] Working principle: During operation, first place the two steel pipes to be welded above the two support platforms 1 respectively. Start the second motor 307 to drive the double-headed screw 306, thereby driving the two support rollers 303 above the support platform 1 to approach each other, forming a support space between the two support rollers 303. Then place the steel pipes between the two support rollers 303 to support the steel pipes. When the steel pipes need to be rotated, start the first motor 304 to make the support rollers 303 rotate. Under the action of friction, the steel pipes are driven to rotate;

[0028] After the steel pipes are placed, control the output end of the cylinder 403 to extend, pushing the slide plate 404 to move along the chute 401. The two push plates 405 are respectively located at one end of the two steel pipes away from each other. The two push plates 405 approach each other to push the two steel pipes closer to each other, so that the ends of the two steel pipes in contact are in contact and close to each other, and then the contact ends of the two steel pipes are welded;

[0029] Since the springs 409 are symmetrically arranged on both sides of the push plate 405, and the contact blocks 408 at the ends of the springs 409 are in contact with the side wall of the mounting table 301, when the two support rollers 303 approach each other, under the action of the springs 409 on both sides, the push plate 405 is located on the axis of symmetry of the two support rollers 303, so that the push plate 405 can keep the position of the steel pipe corresponding.
