Description

Technical Field

[0001] This utility model belongs to the field of pipeline welding technology, and in particular relates to a semi-circular pipe jacket welding device. Background Technology

[0002] In recent years, the demand for complex piping technology in the industrial sector has been increasing. Traditional semi-circular pipe welding technology usually requires a lot of manual operation, which is time-consuming, inefficient and costly. The existing semi-circular pipe jacket welding device not only improves the semi-circular pipe welding process, but also greatly improves the welding effect.

[0003] However, traditional semi-circular pipe jacket welding devices require the use of different diameter clamping heads depending on the scenario. This means that each time the clamping head is changed, the machine needs to be stopped for disassembly and replacement, which increases the downtime of the semi-circular pipe jacket welding device and reduces its welding efficiency. Utility Model Content

[0004] This invention addresses the problem in existing technologies where different diameter clamping heads need to be replaced depending on the scenario. This necessitates downtime for disassembly and replacement each time a clamping head is changed, increasing downtime and reducing welding efficiency of the semi-circular pipe jacket welding device. The following technical solution is proposed:

[0005] A semi-circular pipe jacket welding device includes: a welding machine, both ends of which are fixedly connected to a housing, wherein a plurality of limiting rods are fixedly connected inside the housing at one end, and two clamping blocks are slidably connected to the outer surface of the limiting rods, and bolts are rotatably connected to the surfaces of the two clamping blocks, and a swivel handle is fixedly connected to the other end of the bolts, and baffles are threadedly connected to the outer surfaces of the two bolts, and the two baffles are respectively fixed at the top and bottom edges of the limiting rods.

[0006] As a preferred embodiment of the above technical solution, the number of the limiting rods is set to four, and the four limiting rods are respectively located at the two side edges of the clamping block.

[0007] As a preferred embodiment of the above technical solution, rubber pads are attached to the adjacent end faces of the two clamping blocks.

[0008] As a preferred embodiment of the above technical solution, a water pipe is snapped into the inner part of the outer shell at the other end, and multiple fan-shaped plates are attached to the outer surface of the water pipe. A groove is opened inside the welding machine, and a protrusion is slidably connected inside the groove. The protrusion is fixedly connected to the fan-shaped plate, and a spring is fixedly connected to one end face of the protrusion. The spring is fixedly connected inside the welding machine.

[0009] As a preferred embodiment of the above technical solution, the number of the sector plates is set to four, and the four sector plates are arranged in a circular array with the center of one end face of the water pipe.

[0010] As a preferred embodiment of the above technical solution, the inner wall of the groove is in contact with the outer surface of the protrusion.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) The distance between the two clamping blocks can be adjusted by rotating the plum blossom handle, which avoids the need to replace the clamping blocks when multiple round tubes have different diameters, thereby improving the clamping process of the clamping blocks clamping the round tubes.

[0013] (2) By using fan-shaped plates, protrusions and springs to limit the water pipe from multiple angles, the problem of water pipe displacement when the welding machine is turned off is avoided, thus making the water pipe installation process on the welding machine more stable.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example 1

[0022] This utility model provides a semi-circular pipe jacket welding device, such as Figures 1 to 5As shown, the welding machine includes a welding machine 1, with a housing 2 fixedly connected to both ends of the welding machine 1. Multiple limiting rods 3 are fixedly connected inside one end of the housing 2. Two clamping blocks 4 are slidably connected to the outer surface of the limiting rods 3. Bolts 5 are rotatably connected to the surfaces of the two clamping blocks 4. A plum blossom handle 6 is fixedly connected to the other end of the bolts 5. Baffles 7 are threadedly connected to the outer surfaces of the two bolts 5. The two baffles 7 are fixed at the top and bottom edges of the limiting rods 3, respectively. The welding machine 1 is composed of two parts, and the two parts of the welding machine 1 are rotatably connected to each other.

[0023] like Figure 2 and Figure 4 As shown, there are four limiting rods 3 in total. The four limiting rods 3 are located at the two side edges of the clamping block 4. When the clamping block 4 moves, it is limited by the limiting rods 3, which makes the movement of the clamping block 4 more stable and avoids the problem of the clamping block 4 deviating when it moves, thereby improving the stability of the movement process of the clamping block 4.

[0024] like Figure 2 and Figure 4 As shown, rubber pads 8 are attached to the adjacent end faces of the two clamping blocks 4. When the clamping blocks 4 move, they drive the rubber pads 8 to move as well, and the rubber pads 8 come into contact with the round tube. This avoids deformation of the round tube due to excessive clamping force when the clamping blocks 4 come into contact with the round tube, thereby improving the welding quality.

[0025] like Figure 1 , Figure 3 and Figure 5 As shown, a water pipe 9 is snapped into the inner casing 2 at the other end. Multiple fan-shaped plates 10 are attached to the outer surface of the water pipe 9. A groove is opened inside the welding machine 1, and a protrusion 11 is slidably connected inside the groove. The protrusion 11 is fixedly connected to the fan-shaped plates 10. A spring 12 is fixedly connected to one end face of the protrusion 11. The spring 12 is fixedly connected inside the welding machine 1. First, the welding machine 1 is turned on, and then the water pipe 9 is placed between the four fan-shaped plates 10 at the bottom. The fan-shaped plates 10 are used to pre-position the water pipe 9. Then the welding machine 1 is turned off, which avoids the problem of the water pipe 9 shifting when the welding machine 1 is turned off, thus making the process of installing the water pipe 9 in the welding machine 1 more stable.

[0026] like Figure 1 , Figure 3 and Figure 5 As shown, there are four sector plates 10 in total. The four sector plates 10 are arranged in a circular array with the center of one end face of the water pipe 9. The ends of the four sector plates 10 that are in contact with the water pipe 9 are attached with silicone pads. When the water pipe 9 is placed inside the four sector plates 10, the sector plates 10 clamp the water pipe 9, which avoids the problem of the sector plates 10 causing damage to the surface of the water pipe 9 when clamping the water pipe 9, thereby improving the service life of the water pipe 9.

[0027] like Figure 5 As shown, the inner wall of the groove fits against the outer surface of the protrusion 11. When the protrusion 11 moves, the groove limits its movement, making the movement of the protrusion 11 more stable and thus avoiding the problem of the protrusion 11 shifting during movement, thereby improving the stability of the protrusion 11 during movement.

[0028] Working principle: When using this device, the operator first rotates the plum blossom handle 6, which drives the bolt 5 to rotate. The rotation of the bolt 5 causes one of the clamping blocks 4 to move upward and the other clamping block 4 to move downward. When the clamping block 4 moves, it slides on the outer surface of the limiting rod 3. The limiting rod 3 restricts the upward movement of the clamping block 4, making the upward movement of the clamping block 4 more stable. At this time, the two clamping blocks 4 are in an open and closed state. Then, the operator places the open and closed clamping block 4 on the surface of the round tube and rotates the plum blossom handle 6 in the opposite direction. This reverses the above steps, so that the two clamping blocks 4 clamp the round tube, completing the clamping process of the clamping blocks 4 clamping the round tube. The distance between the two clamping blocks 4 can be adjusted by rotating the plum blossom handle 6, avoiding the need to replace the clamping blocks 4 when multiple round tubes have different diameters, thereby improving the clamping process of the clamping blocks 4 clamping the round tube.

[0029] The staff then turned on the welding machine 1 and installed the water pipe 9 between the four sector plates 10. At this time, one end of each of the four sector plates 10 was in contact with the outer surface of the water pipe 9. The water pipe 9 limited the movement of the protrusions 11, which then squeezed the spring 12, causing the spring 12 to deform. When the surface of the sector plate 10 was completely in contact with the outer surface of the water pipe 9, the squeezing of the spring 12 stopped. The spring 12 then returned to its original position and moved the protrusions 11 in the opposite direction. The protrusions 11 then moved the sector plates 10, which squeezed the water pipe 9 as they moved, thus positioning the water pipe 9. The staff then turned off the welding machine 1 and clamped the water pipe 9 in place. This prevented the water pipe 9 from shifting when the welding machine 1 was turned off, making the installation of the water pipe 9 on the welding machine 1 more stable.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
