Description

Technical Field

[0001] The utility model relates to the technical field of pipeline welding, in particular to a small-diameter pipeline welding butt-joint auxiliary device. Background Art

[0002] Welding is a technology that combines metals by heating, high temperature or high pressure. In the modern construction industry, welding is required for various pipelines used in construction projects to extend the transmission length of various materials. Small-diameter pipelines such as natural gas and metal water pipes cannot be processed too long due to their slenderness to avoid breaking during transportation. Therefore, they need to be welded on site. There are many types of welding equipment and auxiliary tools for small-diameter pipelines, and their functions are constantly being improved to make them more convenient to use.

[0003] In view of this, Chinese Patent No. CN217551531U proposes a small-diameter pipe welding butt auxiliary device, which is provided with pliers, positioning plates a, positioning plates b, screw rods a, ring plates a, ring plates b, screw rings, positioning plates c, positioning plates d and screw rods b, and utilizes the mutual cooperation of ring plates a and b on the pliers to enable the pipe to be firmly fixed between ring plates a and b, thereby avoiding the cumbersome process of welders manually supporting pipe welding. However, most of the above-mentioned technical schemes and existing welding auxiliary tools can only be fixed in the interface area during use to align them to prevent displacement. However, during the docking process, if no force is applied to tightly fit the two pipes together, the gap at the connection is large, resulting in the need for more welding materials to weld them closed during welding. Some of them may crack due to the large welding gap during long-term use, resulting in pipe leakage and increasing safety hazards. Therefore, a small-diameter pipe welding butt auxiliary device is proposed in this design scheme. Utility Model Content

[0024] The docking mechanism 2 includes support frames 201 inserted at both ends of the support base 1, and the inner walls of the two support frames 201 are interspersed with bidirectional screw rods 202. One end of the two support frames 201 is fixed with a holder 203, and both sides of the top of the two holders 203 are fixed with electric telescopic rods 204. Two clamping rings 205 are fixed at the output ends of the four electric telescopic rods 204. A motor 206 is fixed at one side of the support base 1. The outer wall of the bidirectional screw rod 202 and the output end of the motor 206 are fixed with pulleys 207, and a belt strip 208 is transmitted between the outer walls of the two pulleys 207. The inner walls of the two holders 203 and the inner walls of the two clamping rings 205 are fixed with anti-slip pads 209, and the inner wall height of the holders 203 on the two support frames 201 is consistent with the inner wall height of the docking groove 6, so that when the pipe is placed on the holder 203, the bottom of the other end thereof is also in contact with the inner wall of the docking groove 6;

[0025] Furthermore, the outer walls at both ends of the bidirectional screw rod 202 are respectively threadedly connected to the inner walls on one side of the two support frames 201, the inner wall of the support base 1 is provided with a limiting groove 3, and the outer walls of the two support frames 201 are respectively interlaced and connected with the inner walls at both ends of the limiting groove 3, and the support frame 201 is limited by the limiting groove 3 when moving, so that it remains relatively stable during the movement, and the pipes can be pushed to align and fit.

[0026] A support block 4 is fixedly provided at the middle position of the inner wall of the limiting groove 3, and the outer walls at both ends of the bidirectional screw rod 202 are rotatably connected to the inner walls of the two support blocks 4 respectively.

[0027] A docking groove 6 is provided in the middle of the top of the support base 1, and a slide groove 7 is provided at the outer edge of the inner wall of the docking groove 6 on the top of the support base 1.

It is not easy to crack in the later use, which reduces the safety hazard of pipe use. After welding, slide the bellows 801 in the slide groove 7 to adjust the position of the cooling mechanism 8 so that the air outlet slot 805 on one side of the bellows 801 faces the welding area, and start the fan 803 to discharge air, so that the welding area can be quickly cooled after welding, and the staff can use the pipe for connection as quickly as possible, thereby improving the efficiency of pipe welding.
