Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline welding technology, and in particular to a safety welding auxiliary device for vertical shaft pipelines. Background Technology
[0002] The vertical shaft pipeline safety welding auxiliary device aims to improve the efficiency and safety of pipeline welding in vertical shafts. By optimizing the welding operation process, the device can effectively reduce labor costs while improving welding quality.
[0003] In some existing vertical shaft pipeline safety welding auxiliary devices, when users are welding the upper and lower pipes, they first fix the lower pipe to the support platform, then fix the upper pipe in the retaining ring, which is fixed to the wall. When fixing the upper pipe, the position of the retaining ring needs to be adjusted to adjust the welding gap. To adjust the retaining position, a crane is first used to lift the upper pipe, thereby adjusting the welding gap between the upper and lower pipes. After the welding gap is adjusted, the retaining ring is used to fix the upper pipe. After fixing, the upper and lower pipes are welded. Because the welding gap requires high precision, the crane is not stable enough when lifting the upper pipe, making it difficult to ensure stability during adjustment, and thus difficult to control the size of the welding gap, making it difficult to meet the precision requirements of the welding gap.

The adjusting mechanism includes a slide rail, which is fixedly connected to the surface of the connecting plate. A motor is mounted on the surface of the connecting plate. A bidirectional lead screw is rotatably connected inside the slide rail, passing through it. The upper end of the bidirectional lead screw is fixedly connected to the output end of the motor, and the lower end of the bidirectional lead screw is fixedly connected to a friction wheel. Two sliders are slidably connected inside the slide rail, and the bidirectional lead screw passes through and is threadedly connected to the sliders. A fastening ring is fixedly connected to one end of each slider, and a constraint assembly is fixedly connected to the lower end of the slide rail.
[0005] As an improvement to the above technical solution, a spring is wound around the surface of the bidirectional lead screw, and the two ends of the spring are respectively fixedly connected to two sliders.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0017] Please see Figure 1-4 This utility model provides a technical solution: a safety welding auxiliary device for vertical shaft pipelines, including a connecting plate 1, an adjusting mechanism 2 fixedly connected to the surface of the connecting plate 1, and multiple rivets 3 threaded through the surface of the connecting plate 1. The adjusting mechanism 2 includes a slide rail 21, a motor 23 mounted on the surface of the connecting plate 1, a bidirectional lead screw 22 rotatably connected inside the slide rail 21, the upper end of the bidirectional lead screw 22 fixedly connected to the output end of the motor 23, a friction wheel 28 fixedly connected to the lower end of the bidirectional lead screw 22, two sliders 24 slidably connected inside the slide rail 21, the bidirectional lead screw 22 passing through the sliders 24 and threadedly connected to the sliders 24, a fastening ring 25 fixedly connected to one end of the sliders 24, and a constraint component 27 fixedly connected to the lower end of the slide rail 21.
[0018] In this embodiment, the connecting plate 1 is first fixed to the wall vertically using rivets 3. Then, the upper and lower pipes are placed inside the two fastening rings 25 and clamped in place. Then, the motor 23 is driven, causing the output end of the motor 23 to rotate, which in turn drives the bidirectional lead screw 22 and the friction wheel 28 to rotate. As the bidirectional lead screw 22 rotates, it causes the two sliders 24 to move closer to each other. With the help of the fastening rings 25, the upper and lower pipes move closer to each other, thereby adjusting the welding gap. After the welding gap between the pipes is adjusted, the motor 23 is turned off. Then, the friction wheel 28 is frictionally limited by the constraint component 27, which reduces the self-locking load of the motor 23 and extends the service life of the motor 23. Finally, the upper and lower pipes are welded. By setting the adjustment mechanism 2 and using threaded adjustment, the movement of the upper and lower pipes when they move closer to each other can be made more stable, thereby ensuring the stability during adjustment and making it easier to control the size of the welding gap, thus meeting the accuracy requirements of the welding gap.
[0019] Specifically, a spring 26 is wound around the surface of the bidirectional lead screw 22, and the two ends of the spring 26 are fixedly connected to two sliders 24 respectively.
[0020] In this embodiment, when the two sliders 24 approach each other, the spring 26 is compressed. Under the elastic force of the spring 26, the movement of the two sliders 24 becomes more stable, thereby improving the adjustment stability of the mechanism and making it easier to control the size of the welding gap.
[0021] Specifically, the constraint component 27 includes an L-shaped plate 271. The lower end of the slide rail 21 is fixedly connected to the L-shaped plate 271. A threaded rod 272 is threadedly connected to the surface of the L-shaped plate 271. A constraint plate 273 is rotatably connected to one end of the threaded rod 272. A limiting rod 274 is slidably connected to the surface of the L-shaped plate 271. One end of the limiting rod 274 is fixedly connected to the constraint plate 273. The constraint plate 273 is aligned and adapted to the friction wheel 28.
[0022] In this embodiment, when the friction wheel 28 is frictionally limited by the constraint component 27, the threaded rod 272 is rotated first, so that the constraint plate 273 moves. At the same time, the limiting rod 274 slides relative to the L-shaped plate 271. When the constraint plate 273 approaches and fits against the friction wheel 28, the friction wheel 28 can be frictionally limited, thereby frictionally locking the bidirectional lead screw 22. This can share the self-locking load of the motor 23 and extend the service life of the motor 23.
[0023] Specifically, the fastening ring 25 includes a fixing block 251, one end of the slider 24 is fixedly connected to the fixing block 251, one end of the fixing block 251 is fixedly connected to the fixing ring 252, the surface of the fixing ring 252 is threadedly connected to a threaded rod 253 that passes through it, one end of the threaded rod 253 that extends into the interior of the fixing ring 252 is rotatably connected to an arc plate 254, the surface of the fixing ring 252 is slidably connected to a limiting rod 255 that passes through it, one end of the limiting rod 255 that extends into the interior of the fixing ring 252 is fixedly connected to the arc plate 254.
[0024] In this embodiment, when the upper and lower pipes are respectively placed inside the two fastening rings 25 for clamping and fixing, the pipe is first inserted into the inside of the fixing ring 252, and then the threaded rod 253 is rotated, so that the threaded rod 253 and the arc plate 254 rotate relative to each other. Then, in conjunction with the limiting rod 255, the arc plate 254 moves, thereby using the arc plate 254 to clamp and fix the pipe.
[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
