Gas pipeline construction device

Abstract

This invention discloses a gas pipeline construction device, including a base plate; a first fixing plate is fixedly installed at one top end of the base plate, and a second fixing plate is fixedly installed at the other top end of the base plate. Both the first and second fixing plates have horizontally arranged placement holes at their centers. A clamping assembly is installed at the upper end of the placement hole. In use, when the lead screw rotates, it engages with the threaded structure of the first fixing plate, causing the lead screw to move away from the transmission cavity. This movement of the lead screw causes the clamping plate to move away from the transmission cavity, thereby bringing the clamping plate into contact with and clamping the gas pipeline placed in the placement hole. Furthermore, with the assistance of the auxiliary assembly, the end of the gas pipeline closest to the auxiliary assembly is kept horizontal, preventing the gas pipeline from tilting and causing unevenness when two sets of gas pipelines are joined, resulting in low welding quality or even failure to weld.

Description

Technical Field

[0001] This invention relates to the field of gas pipeline construction technology, specifically a gas pipeline construction device. Background Technology

[0002] When laying and installing gas pipelines, if the length of a single gas pipeline is insufficient, it is necessary to weld two adjacent gas pipelines. During the welding process, a welding device is required to connect the gas pipelines to be welded.

[0003] Chinese Patent Publication No. CN216830592U discloses a pipeline docking and positioning device for municipal gas pipeline construction, including a fixing ring, a plurality of fixing rods inside the fixing ring, threads on the outer wall of the fixing rods, a threaded groove in the fixing ring that mates with the threads, a rotating shaft at the bottom of the fixing rods, a fixing part at the bottom of the rotating shaft, a guide ring on one side of the fixing ring, the rotating shaft being rotatably connected to the fixing rods, and the rotating shaft being fixedly connected to the fixing part.

[0004] The aforementioned device uses a combination of fixing parts, fixing rods, threads, grooves, and a rotating shaft to fix the pipe within a fixing ring. During use, multiple fixing rods, threads, grooves, and a rotating shaft need to be manually rotated to clamp the pipe. Then, another set of pipes is placed through a guide ring and connected to the pipe clamped by the fixing rods. However, in actual use, manual operation can easily result in inconsistent travel distances of the fixing rods, causing inconsistencies in the height between the bottom of the clamped pipe and the bottom of the guide ring. This leads to deviations when placing another set of pipes on the guide ring for connection.

[0030] Please see Figures 1-11In this embodiment of the invention, a gas pipeline construction device includes a base plate 1. Preferably, a first fixing plate 2 is fixedly installed at one top end of the base plate 1, and a second fixing plate 12 is fixedly installed at the other top end of the base plate 1. Placement holes 3 are horizontally provided at the centers of both the first fixing plate 2 and the second fixing plate 12. An extension plate is provided on the side of the first fixing plate 2 and the second fixing plate 12 that is relatively far apart, facilitating the placement of the gas pipeline. A clamping component is provided at the upper end of the placement hole 3. An auxiliary component is provided on the side of the first fixing plate 2 near the second fixing plate 12. The auxiliary component is slidably connected to the top of the base plate 1. In the initial state, the clamping component in the placement hole 3 is at the top position within the placement hole 3. At this time, the two sets of gas pipelines to be welded are sequentially... The gas pipe is placed in the placement holes 3 on the first fixing plate 2 and the second fixing plate 12, and then pushed towards the auxiliary component. Under the action of the auxiliary component, the end of the gas pipe near the auxiliary component is kept horizontal, avoiding the possible tilting of the gas pipe, which could cause unevenness when the two sets of gas pipes are connected, resulting in low welding quality or failure to weld. When the auxiliary component moves towards the second fixing plate 12, the auxiliary component drives the clamping component in the first fixing plate 2 to move relative to the base plate 1 to clamp the gas pipe in the first fixing plate 2. When the auxiliary component moves to both sides of the base plate 1, the auxiliary component drives the clamping component in the second fixing plate 12 to move towards the base plate 1 to clamp the gas pipe in the second fixing plate 12.

[0031] Further, preferably, the clamping assembly includes a clamping plate 8; the clamping plate 8 is symmetrically arranged along the center of the top of the placement hole 3, and a lead screw 7 is rotatably connected to the end of the clamping plate 8 away from the base plate 1. The lead screw 7 is rotatably connected to the inner wall of the first fixing plate 2. A transmission cavity 14 communicating with the placement hole 3 is provided in the side wall of the top of the first fixing plate 2 and the second fixing plate 12. The end of the lead screw 7 away from the clamping plate 8 extends into the transmission cavity 14. The clamping plate 8 has an arc-shaped structure, and the lead screw 7 is diagonally arranged at the top of the placement hole 3. The side wall and the side wall of the first fixed plate 2 are rotatably connected by a threaded structure. In the initial state, the lead screw 7 is retracted to the lowest position in the transmission cavity 14, so that the clamping plate 8 is as close as possible to the transmission cavity 14. When the lead screw 7 rotates, the lead screw 7 moves away from the transmission cavity 14 through the threaded structure of the first fixed plate 2. The movement of the lead screw 7 causes the clamping plate 8 to move away from the transmission cavity 14, so that the clamping plate 8 contacts and clamps the gas pipe placed in the placement hole 3.

[0032] Preferably, a telescopic rod is fixedly provided between the side of the clamping plate 8 near the transmission cavity 14 and the placement hole 3. The telescopic rod keeps the clamping plate 8 in a fixed state when the screw 7 rotates, thus preventing the clamping plate 8 from rotating and causing it to fail to fit and conform to the outer periphery of the gas pipeline.

[0033] Please see Figure 2 , Figure 5 , Figure 6 Preferably, a driven gear 20 is fixedly connected to the end of the lead screw 7 away from the clamping plate 8. A drive gear 16 is driven and engaged on one side of the driven gear 20. A first coil 23 is fixedly connected to the end of the drive gear 16 away from the clamping plate 8. A first pull rope 21 is wound on the first coil 23. The end of the first pull rope 21 away from the first coil 23 slides through the side wall of the first fixed plate 2 and is fixedly connected to the auxiliary component. A base 22 is rotatably provided at the bottom end of the drive gear 16, and a torsion spring is provided between the base 22 and the drive gear 16. The torsion spring allows the drive gear 16 to automatically rotate and reset when no force is applied. The base 22 and the side of the transmission cavity 14 near the base plate 1 are elastically connected by a spring. In use, in the initial state, the auxiliary component is in contact with the first fixed plate 2. When the gas pipe is inserted through the placement hole 3 on the first fixed plate 2 and the gas pipe is in contact with the auxiliary component, the auxiliary component can keep the gas pipe horizontal. The gas pipe can be pushed towards the second fixed plate 12, so that the auxiliary component can rotate and reset. The auxiliary component moves towards the second fixed plate 12, thereby pulling the first pull rope 21, causing it to spread out on the first coil 23. This causes the first coil 23 to rotate, driving the drive gear 16 to rotate. The drive gear 16 then drives the driven gear 20 to rotate, which in turn drives the lead screw 7 to rotate. The rotation of the lead screw 7, through its threaded engagement with the side wall of the first fixed plate 2, moves the lead screw 7 towards the gas pipe, pushing the clamping plate 8 to contact the gas pipe and clamping and positioning it. Then, another set of gas pipes is inserted through the placement hole 3 in the second fixed plate 12 and pushed towards the auxiliary component, causing the other set of gas pipes to contact and engage with the auxiliary component. This allows the auxiliary component to move towards both sides of the base plate 1. At this time, the movement of the auxiliary component causes the clamping component in the second fixed plate 12 to move towards the gas pipes on the second fixed plate 12 and clamp and position them. Through the cooperation of the auxiliary component and the clamping component, the opposite ends of the two sets of gas pipes are kept in a horizontally aligned state, thus facilitating their welding.

[0034] Please see Figure 2 , Figure 5Preferably, a square groove is provided on the side of the clamping plate 8 away from the lead screw 7, and a slider 9 is slidably connected in the square groove. The clamping plate 8 and the lead screw 7 are hollow structures, and a first flexible tube 15 is rotatably connected to the end of the lead screw 7 away from the clamping plate 8. The square groove and the first flexible tube 15 are connected. The end of the first flexible tube 15 away from the lead screw 7 passes through the side wall of the first fixed plate 2 and is connected to an airbag 24. A connecting rod 17 is fixedly provided at the top of the airbag 24, and a trigger block 171 is fixedly connected to the bottom of the connecting rod 17 through the airbag 24. The airbag 24 slides against the inner wall of the first fixed plate 2. The trigger block 171 is slidably attached to the transmission cavity 14. An arc-shaped plate is fixedly provided at the end of the base 22 away from the lead screw 7. The arc-shaped plate is slidably engaged with the end of the trigger block 171. The airbag 24 is an elastic telescopic structure. When gas is introduced into the airbag 24, the airbag 24 expands upward. The bottom of the airbag 24 is fixedly connected to the inner wall of the first fixed plate 2. The airbag 24 is a ring structure. When the airbag 24 stops supplying gas, the airbag 24 can elastically contract and reset. The bottom of the trigger block 171 near the arc-shaped plate is provided with an inclined surface facing the clamping plate 8.

[0035] In use, in the initial state, the slider 9 protrudes from the side wall of the clamping plate 8, the airbag 24 contracts, the trigger block 171 protrudes from the placement hole 3, and the end of the trigger block 171 is in contact with the end of the arc plate. The drive gear 16 meshes with the driven gear 20. When the auxiliary component moves towards the second fixed plate 12, the auxiliary component causes the first coil 23 to rotate through the first pull rope 21. The rotation of the first coil 23 drives the drive gear 16 to rotate, which in turn drives the driven gear 20 to rotate. The driven gear 20 then drives the lead screw 7 to rotate, causing the lead screw 7 to move towards the base plate 1 in cooperation with the first fixed plate 2. During the movement of the lead screw 7 and the driven gear 20, the driven gear 20 and the drive gear 16 remain meshed. When the clamping plate 8 moves, causing the slider 9 to contact the gas pipe and be pushed to retract into the clamping plate 8, the slider 9 compresses the gas in the square groove through the clamping plate 8, the lead screw 7, and the first hose 1. 5. Gas is delivered into the airbag 24, causing the airbag 24 to expand upwards. This causes the connecting rod 17 to move upwards, and the movement of the connecting rod 17 causes the trigger block 171 to move upwards and separate from the arc plate. Subsequently, the base 22 moves towards the trigger block 171 under the action of the corresponding spring, causing the drive gear 16 to separate from the driven gear 20. It should be noted that when one set of sliders 9 retracts into the square groove, the corresponding gas delivered into the airbag 24 will push the trigger block 171 to move upwards. However, the distance that the trigger block 171 moves is the position of the inclined surface above the corresponding end of the arc plate. At this time, the drive gear 16 is still meshed with the driven gear 20. When the other set of sliders 9 retracts into the square groove, the trigger block 171 will separate from the arc plate. This ensures that the trigger block 171 will only separate from the arc plate when both sets of sliders 9 retract into the square groove, thereby causing the two sets of drive gears 16 to separate from the driven gear 20 simultaneously.

[0036] Please see Figure 5 Preferably, the slider 9 and the clamping plate 8 are rotatably provided with ball bearings 28 on the side away from the lead screw 7. Multiple sets of ball bearings 28 are arrayed on the clamping plate 8 and the slider 9, and the end of the ball bearing 28 away from the lead screw 7 protrudes from the side wall of the clamping plate 8 and the slider 9. In this way, when the clamping plate 8 moves toward and clamps the gas pipeline, the slider 9 comes into contact with the gas pipeline. After the clamping plate 8 clamps the pipeline, it can also push the pipeline toward the auxiliary component, so that the clamping component can clamp gas pipelines of different sizes. After clamping, it can also push the gas pipeline to move, so that the end of the gas pipeline moves to the center position of the first fixing plate 2 and the second fixing plate 12, thereby facilitating the welding operation of the two sets of gas pipelines.

[0037] Please see Figures 1-4 , Figure 7-11Preferably, the auxiliary components include a horizontal plate 5; a mounting groove 10 is provided on the top of the base plate 1 and on the side near the first fixed plate 2, and through grooves penetrating the top of the base plate 1 are provided on both sides of the mounting groove 10. A sliding plate 13 is slidably disposed in the mounting groove 10. The horizontal plate 5 is slidably disposed at one end of the sliding plate 13 near the second fixed plate 12, and the horizontal plate 5 is symmetrically disposed along the center of the sliding plate 13. The horizontal plate 5 is slidably attached to the side wall of the first fixed plate 2. An extension groove 11 communicating with the mounting groove 10 is provided at the center of the base plate 1. The end of the first pull rope 21 on the first fixed plate 2 away from the first coil 23 is fixedly connected to the end of the sliding plate 13 away from the second fixed plate 12. The top height of the horizontal plate 5 is flush with the center of the placement hole 3. The sliding plate 13 and the mounting groove 10 are elastically connected by a spring. The extension groove 11 and the mounting groove 10 are perpendicular to each other, and the horizontal plate 5 is slidably attached to the mounting groove 11.

[0038] In use, initially, the slide plate 13 is positioned close to the first fixed plate 2, and the horizontal plate 5 is flush with the side wall of the first fixed plate 2. When welding the gas pipeline, a set of gas pipelines is inserted through the placement holes 3 on the first fixed plate 2 and then pushed towards the second fixed plate 12. This prevents the gas pipelines from tilting under the constraint of the horizontal plate 5. The movement of the gas pipelines under force pushes the horizontal plate 5 towards the second fixed plate 12, which in turn causes the slide plate 13 to move towards the second fixed plate 12. The movement of the slide plate 13 pulls the first pull rope 21, causing the first coil 23 to unwind and rotate. This, in turn, tightens the gripping mechanism on the gas pipeline. When the two sets of sliders 9 move and retract into the square groove, the drive gear 16 and the driven gear 20 separate. At this time, under the action of the ball bearing 28, the gas pipe can be pushed to move in the direction of the extension groove 11. When the horizontal plate 5 moves to the position corresponding to the extension groove 11, it can no longer push the gas pipe to move. Then, another set of gas pipes is inserted into the placement hole 3 of the second fixing plate 12 and pushed in the direction of the horizontal plate 5. When the other set of gas pipes is in contact with the horizontal plate 5, the horizontal plate 5 will slide from the slide plate 13 into the extension groove 11. The sliding of the horizontal plate 5 will cause the clamping component in the second fixing plate 12 to move towards the gas pipe and clamp the gas pipe. Then, the welding work can be carried out.

[0039] Furthermore, preferably, a toothed plate 27 is fixedly provided at the bottom of the horizontal plate 5. The two sets of toothed plates 27 have teeth on opposite sides, and a synchronous gear is connected between the two sets of toothed plates 27. The synchronous gear is located at the center of the toothed plate 27 and is rotatably connected to the slide plate 13. In this way, when one set of toothed plates 27 moves to extend beyond the side wall of the slide plate 13, the synchronous gear causes the other set of toothed plates 27 to move synchronously beyond the side wall of the slide plate 13, thereby causing the two sets of horizontal plates 5 to move synchronously away from the slide plate 13. The two sets of horizontal plates 5 are respectively provided on both sides of the end of the slide plate 13. The toothed plate 27 is slidably adapted to the extension groove 11. When the end of the slide plate 13 moves to correspond with the extension groove 11, the toothed plate 27 corresponds to the extension groove 11, that is, the toothed plate 27 can slide into the extension groove 11, thereby causing the horizontal plate 5 to move into the extension groove 11.

[0040] Please see Figure 1-Figure 2 Preferably, a gas chamber communicating with the placement hole 3 is provided at the bottom of the first fixing plate 2 near the placement hole 3. An arc-shaped block 4 is slidably arranged in the gas chamber, and a spring is provided between the arc-shaped block 4 and the gas chamber. A second flexible hose 18 is provided between the bottom of the gas chamber and the sliding plate 13. When the gas pipe is placed in the placement hole 3 on the first fixing plate 2, the gas pipe will push the arc-shaped block 4 downward and retract it in the gas chamber, thereby allowing the gas in the gas chamber to be transported into the second flexible hose 18. When the gas pipe is removed from the placement hole 3, the arc-shaped block 4 can move and reset under the action of the spring.

[0041] Please see Figure 1-Figure 2 , Figure 9 A gas storage tank 30 is provided inside the slide plate 13. The end of the second hose 18 away from the arc block 4 is connected to the gas storage tank 30, and the connection between the second hose 18 and the gas storage tank 30 is located on the side of the gas storage tank 30 near the toothed plate 27. A piston plate is elastically provided inside the gas storage tank 30. The piston plate is located on the side of the gas storage tank 30 and the connection between the second hose 18 away from the toothed plate 27. A horizontal plate is fixedly provided on a set of toothed plates 27 near the gas storage tank 30. A telescopic tube 29 is fixedly provided between the horizontal plate and the inner wall of the mounting groove 10. The end of the telescopic tube 29 away from the horizontal plate is connected to the gas storage tank 30. A spring is fixedly provided between the end of the horizontal plate away from the telescopic tube 29 and the mounting groove 10. When a set of gas pipes is placed on the arc block 4, the arc block 4 moves downward, causing the gas storage tank 30 to be filled with gas. This allows the horizontal plate 5 to move into the extension groove 11 and separate from the end of the set of gas pipes after it moves to the extension groove 11, thus facilitating subsequent docking and welding work.

[0042] In practical use, in the initial state, the piston plate is positioned close to the second hose 18, and both sets of toothed plates 27 are within the slide plate 13 under the action of the horizontal plate and the spring, thus causing the horizontal plate 5 to be positioned on both sides of one end of the slide plate 13, and the telescopic tube 29 to be in a retracted state. When the arc-shaped block 4 moves downward and retracts into the air chamber, the gas inside is transported to the air storage tank 30 through the second hose 18. At this time, when the end of the slide plate 13 has not moved to the position of the extension groove 11, that is, when the toothed plate 27 and the horizontal plate 5 are not aligned with the extension groove 11, the gas will push the piston plate to move away from the toothed plate 27. When the horizontal plate 5 and the toothed plate 27 move to the position corresponding to the extension groove 11, the piston plate elastically resets, allowing the gas in the air storage tank 30 to enter the telescopic tube 29, causing the telescopic tube 29 to expand and extend, thereby pushing one set of toothed plates 27 into the extension groove 11 through the horizontal plate, and through the action of the synchronous gear, the other set of toothed plates 27 will also move synchronously into the corresponding extension groove 11.

[0043] Please see Figure 7-Figure 8 Preferably, an auxiliary plate 6 is elastically connected to the side of the horizontal plate 5 near the second fixed plate 12. The top side wall of the mounting groove 10 is provided with a notch 26 for sliding engagement of the auxiliary plate 6. An inclined surface is provided on the two opposite sides. In use, the auxiliary plate 6 protrudes from the horizontal plate 5 and engages with the notch 26. This allows the horizontal plate 5 to continuously block one set of gas pipes when one set is clamped and the other set of gas pipes is not placed, preventing it from moving and causing deviations in subsequent docking. When the other set of gas pipes is placed, it pushes the auxiliary plate 6, causing the auxiliary plate 6 to separate from the notch 26, allowing the horizontal plate 5 to move into the extension groove 11. Then, it pushes the pipes to align the two sets of pipes, ensuring that the two sets of pipes are horizontally aligned. After the horizontal plate 5 moves and resets, the inclined surface allows the auxiliary plate 6 to engage with the notch 26 again for the next use.

[0044] In the initial state, the auxiliary plate 6 and the notch 26 are engaged. At this time, the relative positions of the horizontal plate 5 and the sliding plate 13 are limited. Even if the horizontal plate 5 moves to the position of the corresponding extension groove 11, the gas in the gas storage tank 30 will not be delivered to the telescopic pipe 29 to expand. When another set of gas pipes is inserted into the placement hole 3 on the second fixed plate 12 and pushed to contact the auxiliary plate 6, and pushes the auxiliary plate 6 to move towards the horizontal plate 5 to fit together, the bottom of the auxiliary plate 6 separates from the notch 26. Then the gas in the gas storage tank 30 is delivered to the telescopic pipe 29 to expand, thereby moving the toothed plate 27 and the horizontal plate 5 into the extension groove 11, and then separating the horizontal plate 5 from the pipe, so as not to affect the docking work. Moreover, the cooperation of the horizontal plate 5 and the auxiliary plate 6 ensures that the two sets of pipes are kept horizontally aligned during docking, and there will be no problem of one set of pipes tilting.

[0045] Please see Figures 9-11A transmission disc 31 is rotatably mounted inside the top side wall of the base plate 1. A second coil 25 is engaged with the side of the transmission disc 31 away from the first fixed plate 2. A corresponding first pull rope 21 on the second fixed plate 12 is fixedly connected to the second coil 25. A third coil is fixedly mounted at the top center of the transmission disc 31. A second pull rope is wound on the third coil. A push plate 19 is fixedly mounted at the end of the second pull rope away from the third coil. The push plate 19 is slidably connected to the inner wall of the base plate 1. The end of the push plate 19 away from the second fixed plate 12 slides into the extension groove 11. The transmission disc 31 and the second coil 25 are both located at the top center of the base plate 1. In use, when the toothed plate 27 moves into the extension groove 11, the toothed plate... Plate 27 pushes push plate 19 to move away from transmission plate 31. The movement of push plate 19 pulls the second pull rope, causing it to spread out on the third reel, which makes transmission plate 31 rotate. The rotation of transmission plate 31 drives the second reel 25 to rotate. The rotation of the second reel 25 winds up the corresponding first pull rope 21 on the second fixed plate 12. Then, through the cooperation of the first reel 23, drive gear 16 and driven gear 20, the screw 7 on the second fixed plate 12 rotates and extends into the placement hole 3. The clamping plate 8 completes the clamping work of another set of gas pipes. After the clamping work is completed, the other set of gas pipes is pushed to move towards the first set of gas pipes to align the ends of the two, thereby facilitating the welding work.

[0046] Please see Figures 1-11 Preferably, a vent (not shown in the figure) is provided on the side wall of the first fixed plate 2. The vent is connected to the air chamber and the first hose 15, and a valve is provided in the vent. In the initial state, the valve is closed and the arc block 4 extends into the placement hole 3. In this way, after the arc block 4 moves downward, the gas in the air chamber can be transported to the air storage tank 30. When the welding work is completed, the valve is opened so that the gas in the telescopic tube 29 is discharged through the air storage tank 30, the second hose 18, the air chamber, and the gas in the first hose 15 and the air bag 24. Then, after the toothed plate 27 moves and resets, the first pull rope 21 is no longer under force, and the trigger block 171 moves and resets so that the base 22 moves and resets. At the same time, the drive gear 16 rotates and resets. At this time, the drive gear 16 rotates and drives the driven gear 20 to rotate and reset, which in turn causes the lead screw 7 to rotate and reset, so that the clamping plate 8 and the pipe are separated. Finally, the slide plate 13 moves and resets. After the pipe is removed, the arc block 4, the slider 9, etc. are reset and the valve can be closed for the next use.
