Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 、 Figure 3 and Figure 4 The utility model provides an embodiment of a pipeline positioning device for welding pipelines, comprising an outer plate 1, the left and right sides of the inner wall of the outer plate 1 are fixedly connected to the limit blocks 4, the left and right sides of the inner wall of the outer plate 1 are provided with a movable plate 3, the adjacent sides of the two movable plates 3 are fixedly connected to a movable block 6, the top of the movable block 6 is provided with a groove 9, the groove 9 is slidably connected with the limit block 4, the groove 9 and the limit block 4 can limit the movement range and direction of the movable block 6; the front and rear sides of the outer wall of the movable plate 3 are rotatably connected to the expansion column 5, the expansion column 5 can increase the contact area with the ground; the front and rear sides of the top of the movable plate 3 are provided with a limit column 7, the outer wall of the limit column 7 passes through the movable plate 3 and the expansion column 5 and is fixedly connected to the support plate 8, the limit column 7 and the support plate 8 can adjust the height of the movable plate 3; a plurality of hanging rings 10 are fixedly connected to the middle of the bottom side of the outer wall of the outer plate 1, and the hanging ring 10 can be connected to the lifting rope; a lifting clamping mechanism 2 is provided on the top of the movable plate 3, and the lifting clamping mechanism 2 is used to fix and adjust the height of the device;

[0033] Specifically, when using the device, since part of the pipeline is buried underground, the surrounding soil needs to be excavated during welding. When the pipelines on both sides need to be hung, the movable plate 3 is pulled out, thereby driving the movable block 6 to be pulled out from the outer plate 1. Due to the limitation of the limit block 4, the movable block 6 cannot be completely pulled out from the outer plate 1. Subsequently, the expansion columns 5 on both sides of the movable plate 3 are pulled to increase the contact area of ​​the movable plate 3, so that the device is placed above the excavated tunnel. The length of the movable block 6 pulled out from the outer plate 1 can be adjusted according to the width of the tunnel. Subsequently, the connecting rope is fixed by the hanging ring 10 to fix the pipelines on both sides. The device can also be placed at the bottom of the two pipelines. By adjusting the position of the limit columns 7 on both sides, the height of the device can be changed to complete the fixing of the top.

[0034] Reference Figure 1 、 Figure 4 and Figure 5The lifting and lowering engaging mechanism 2 includes a plurality of limiting slots 201, and the plurality of limiting slots 201 are opened on the outside of the limiting column 7. The top and rear sides of the movable plate 3 are slidably connected with a card plate 202, and the card plate 202 is engaged with the limiting slot 201. The engagement of the card plate 202 with the limiting slot 201 can fix the position of the limiting column 7; the adjacent sides of the two card plates 202 are rotatably connected with a rotating bar 203, and the adjacent bottom sides of the two card plates 202 are fixedly connected with a spring 204, and the spring 2 One side of 04 is fixedly connected to the moving plate 3, and the adjacent side of the two rotating bars 203 is rotatably connected to the rotating plate 206. The top of the moving plate 3 is fixedly connected to the U-shaped cover plate 207. The top of the U-shaped cover plate 207 is provided with a T-shaped rotating column 205. The outer wall of the T-shaped rotating column 205 passes through the U-shaped cover plate 207 and is fixedly connected to the rotating plate 206. The rotation of the T-shaped rotating column 205 will drive the rotating plate 206 to rotate, and at the same time drive the rotating bar 203 to move, and then drive the clamping plate 202 to move;

[0035] Specifically, when it is necessary to adjust the position of the limit columns 7 on both sides, the T-shaped rotating column 205 is rotated, which will then drive the rotating plate 206 to rotate, thereby pulling the rotating bars 203 on both sides to move relative to each other, thereby pulling the card plate 202 to move, so that the card plate 202 and the limit slot 201 are disengaged. Then, after adjusting the position of the limit column 7, the rotation of the T-shaped rotating column 205 is released. At this time, under the reset of the spring 204, the card plate 202 is engaged with the limit slot 201, thereby completing the fixation of the adjusted position.

[0036] Reference Figure 1 、 Figure 2 and Figure 4 , the bottom of the support plate 8 is fixedly connected with a plurality of fixing blocks 12, and the outer wall of the deployment column 5 is fixedly connected with a plurality of anti-slip blocks 11, the fixing blocks 12 can improve the anti-slip ability of the support plate 8, and the anti-slip blocks 11 can also improve the anti-slip ability of the deployment column 5; the outer side of the deployment column 5 is slidably connected with a pulling handle 13, and a notch 14 is provided on the outer side of the pulling handle 13. The pulling handle 13 can facilitate pulling out the deployment column 5, and the notch 14 on the top can facilitate taking out the pulling handle 13; the top of the outer wall of the outer plate 1 is fixedly connected with a U-shaped concave plate 15, and the inner wall of the U-shaped concave plate 15 is provided with a plurality of anti-slip grooves 16. The U-shaped concave plate 15 can well place the pipeline above the device, and the anti-slip grooves 16 can improve the anti-slip ability of the U-shaped concave plate 15 and the pipeline;

[0037] Specifically, by setting the fixing block 12, the anti-slip performance of the support plate 8 can be significantly enhanced. At the same time, the anti-slip block 11 also improves the anti-slip effect of the unfolding column 5. Pulling the handle 13 makes it convenient to pull out the unfolding column 5, and the notch 14 above the handle makes it easy for the user to easily remove the pulling handle 13. In addition, the U-shaped concave plate 15 provides a stable placement position for the pipeline, and the anti-slip groove 16 further enhances the anti-slip effect between the U-shaped concave plate 15 and the pipeline.

[0038] Reference Figure 1 、 Figure 2 and Figure 3 A fixing plate 17 is fixedly connected to the left side of the front end of the top of the outer wall of the outer panel 1, and a nameplate 18 is fixedly connected to the top of the fixing plate 17. The nameplate 18 can mark the basic information of the device; a spirit level 19 is fixedly connected to the front side of the top of the outer wall of the outer panel 1, and a plurality of scale lines 20 are provided on the top of the spirit level 19. The spirit level 19 can provide feedback on whether the device is in a horizontal state, and the deviation can be known in real time through the scale lines 20; a light board 21 is fixedly connected to the bottom of the outer panel 1, and a plurality of lighting lamps 22 are fixedly connected to the bottom of the light board 21. The light board 21 and the lighting lamps 22 can provide lighting when used at night or in dimly lit areas;

[0039] Specifically, the basic information of the device can be identified through the nameplate 18, the spirit level 19 is used to detect whether the device is level and display the deviation in real time through the scale line 20. In addition, the combination of the light board 21 and the lighting lamp 22 ensures that the device can provide necessary lighting when used at night or in a low-light environment.

[0040] Working principle: Before using the device, first, when operating the equipment, since part of the pipeline is buried underground, the surrounding soil needs to be excavated before welding. When the pipelines on both sides need to be hoisted, the movable plate 3 is pulled out to drive the movable block 6 to be pulled out from the outer plate 1. Due to the constraint of the limit block 4, the movable block 6 cannot be completely separated from the outer plate 1. Then, the expansion columns 5 on both sides of the movable plate 3 are pulled to increase the contact area of ​​the movable plate 3, and the equipment is placed above the excavated trench. According to the width of the trench, the length of the movable block 6 pulled out from the outer plate 1 can be adjusted. Subsequently, the connecting rope is fixed by the hanging ring 10 to achieve stable positioning of the pipelines on both sides. In addition, the device can also be placed at the bottom of the two pipelines. By adjusting the position of the limit columns 7 on both sides, the height of the device can be changed, thereby achieving stable fixation of the top of the pipeline.

[0041] And through the lifting and locking mechanism 2, when the position of the limit column 7 needs to be adjusted, the T-shaped rotating column 205 is rotated to drive the rotation of the rotating plate 206, thereby prompting the rotating bars 203 on both sides to move relative to each other, thereby causing the card plate 202 to move, and then the locking state between the card plate 202 and the limit slot 201 is released. After the adjustment is completed, it is only necessary to release the rotation force on the T-shaped rotating column 205, and the reset force of the spring 204 will prompt the card plate 202 to re-engage with the limit slot 201, thereby achieving a stable fixation of the adjusted position.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
