DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] As Figures 1-5As shown, this embodiment provides a heavy-duty pipe welding joint positioning device, including a positioning mechanism 1. The positioning mechanism 1 includes two placement frames 2. A positioning sleeve 202 is installed on the lower surface of the placement frame 2. A support frame 3 is provided on the outer side of the placement frame 2. The support frame 3 includes a T-shaped support plate 301, a second moving roller 302, and an insertion rod 303. The positioning sleeve 202 is installed on the lower surface of the placement frame 2 at the position corresponding to the insertion rod 303. The support frame 3 is movably connected to the positioning sleeve 202 through the insertion rod 303. A moving groove 201 is opened on the upper surface of the placement frame 2. A positive and negative threaded rod 204 is installed inside the moving groove 201. A slider 205 is installed on the outer side of the positive and negative threaded rod 204. The slider 205 is meshed and rotatably connected with the positive and negative threaded rod 204. A pipe limiting rod 4 is installed above the slider 205. The pipe limiting rod 4 is engaged with the slider 205.

[0022] like Figures 2-3 As shown, in this embodiment, first moving rollers 203 are installed on both sides of the positioning sleeve 202 on the lower surface of the placement frame 2. The first moving rollers 203 are movably connected to the placement frame 2. The placement frame 2 is a T-shaped structural component. A crank handle 206 is installed on one end of the positive and negative threaded rod 204 on the outside of the placement frame 2. The crank handle 206 is fixedly connected to the positive and negative threaded rod 204. A rotating bearing is installed on the outside of the positive and negative threaded rod 204 near the end of the crank handle 206.

[0023] The working principle of this utility model is as follows: During use, the support frame 3 inside the two placement racks 2 is pulled outwards. After placing the two pipes to be welded on top of the two placement racks 2, one end of the pipe is aligned with the top of the T-shaped support plate 301. Torque is applied to the crank handles 206 on the outer sides of the two placement racks 2, causing the slider 205 to rotate and engage with the threaded rod 204. The slider 205 moves towards the center of the placement rack 2 within the moving groove 201, thus facilitating the welding of the pipes. After the pipe is used for limiting, the support frame 3 under the two placement frames 2 is moved towards each other by the control. The second moving roller 302 under the support frame 3 can easily drive the pipe to move. The insertion rods 303 at both ends are pushed into the positioning sleeves 202 on the lower surface of the opposite placement frame 2. Then the welding joints of the pipes at both ends will come into contact with each other. Then, the torque is applied to the crank handle 206 again, and the pipe limiting rod 4 is used to clamp and position the pipe in the center of the placement frame 2. Therefore, it can be ensured that the pipe will not move during welding.
