[0002] A long-distance pipeline refers to a pipeline used for transporting commercial media between a production area, a storage depot, and a user unit. During the construction of the long-distance pipeline infrastructure, it is mostly necessary to butt the pipelines and then perform subsequent welding and sealing.

[0003] In the Chinese patent with the publication number CN220636852U, a butt joint device for natural gas long-distance pipeline welding is disclosed. In this technical solution, the second hydraulic rod drives the clamping plate to move downward until the clamping plate contacts the outer side of the pipeline, and the pipeline is fixed by pressing the clamping plate, so as to avoid the pipeline from tilting up and affecting the welding process.

[0004] The butt joint device in the above comparative patent cannot generate a lateral thrust. When the device clamps and fixes the pipeline, it is necessary to manually align the two pipelines first and then fix the pipeline. This method of butt joint is more troublesome and prone to errors, resulting in gaps in subsequent welding or uneven thickness of the weld layer, thus affecting the service performance of the long-distance pipeline. Therefore, a butt joint device for long-distance pipeline welding is proposed to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The principles and features of the present utility model will be described below with reference to the drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0025] Embodiment: As shown in Figure 1 、 2 、FIG. 3, the long - distance pipeline welding and butt - joint device of this embodiment includes a liftable base 1, two groups of clamping assemblies 2 and a translation mechanism. Among them, the above - mentioned clamping assembly 2 is installed at one end of the upper part of the above - mentioned base 1, and the other group of the above - mentioned clamping assemblies 2 is arranged at the other end of the upper part of the above - mentioned base 1. The above - mentioned translation mechanism is installed on the upper part of the above - mentioned base 1 and is connected to the other group of the above - mentioned clamping assemblies 2 for driving this group of clamping assemblies 2 to translate closer to or farther away from one of the above - mentioned clamping assemblies 2.

[0026] When the long-distance pipeline welding and butt-jointing device of this embodiment is in use, the end of one long-distance pipeline is clamped in one set of clamping components 2, and the end of the other long-distance pipeline is clamped in another set of clamping components 2. Then, the translation mechanism drives the other set of clamping components 2 and the long-distance pipeline to move closer to the long-distance pipeline clamped in one set of clamping components 2, so that the ports of the two long-distance pipelines are coaxially butted. Then, welding can be carried out by using a welding tool. Overall, the structural design is simple and reasonable. The two pipelines are clamped by two sets of clamping components, and then the coaxial butt-jointing is realized through the translation mechanism, which improves the stability and accuracy of welding and butt-jointing and avoids errors caused by manual butt-jointing.

[0027] In this embodiment, the above-mentioned base 1 includes a bottom plate 11, a mounting plate 12 and a lifting component. The above-mentioned bottom plate 11 is horizontally arranged, the above-mentioned mounting plate 12 is horizontally arranged above the above-mentioned bottom plate 11, and the above-mentioned lifting component is connected between the above-mentioned bottom plate 11 and the mounting plate 12. The height of the mounting plate 12 relative to the bottom plate 11 is adjusted by the lifting component, so as to achieve the purpose of adjusting the clamping height matching between the two sets of clamping components 2 and the two long-distance pipelines, which is convenient for subsequent clamping and moving butt-jointing.

[0028] As a preferred implementation manner, connecting pieces 17 are respectively arranged at positions near both ends on both sides of the above-mentioned bottom plate 11. Bolts 18 threadedly connected with the connecting pieces 17 penetrate through the connecting pieces 17, and a support disk 19 is fixedly installed at the lower end of the above-mentioned bolts 18.

[0029] In the above-mentioned implementation scheme, during use, the bolt 18 can be operated to drive the support disk 19 to rotate and finely adjust the height up and down, so that the support disk 19 stably supports on the ground, thereby ensuring that the base 1 can stably support on the ground, which is beneficial to subsequent clamping and welding operations.

[0030] As a preferred implementation manner, the above-mentioned lifting component includes a bidirectional internal threaded tube 13 and two threaded straight rods 14. The inner wall of the above-mentioned bidirectional internal threaded tube 13 is provided with threads with opposite spiral directions at both ends from the middle to both ends. The two above-mentioned threaded straight rods 14 are respectively vertically fixed in the middle of the upper end of the above-mentioned bottom plate 11 and the middle of the lower end of the above-mentioned mounting plate 12. The above-mentioned bidirectional internal threaded tube 13 is vertically arranged, and its two ends are respectively screwed with the two above-mentioned threaded straight rods 14.

[0031] In the above-mentioned implementation scheme, by rotating the bidirectional internal threaded tube 13, the bidirectional internal threaded tube 13 can be screwed into the two threaded straight rods 14. When screwing in, since the thread directions at both ends of the bidirectional internal threaded tube 13 are opposite, when operating the bidirectional internal threaded tube 13, the two threaded straight rods 14 approach or move away from each other relatively, so as to achieve the purpose of adjusting the distance or height between the mounting plate 12 and the bottom plate 11, and the operation is relatively convenient.

[0032] In this embodiment, an operating rod or handrail for facilitating the rotation of the double - internal - thread pipe 13 can be designed on the outer surface of the double - internal - thread pipe 13.

[0033] As a preferred embodiment, it further includes multiple groups of guiding components. The guiding components include a guiding sleeve 15 and a guiding straight rod 16 which are respectively arranged vertically. The guiding sleeve 15 is fixed to the upper end of the bottom plate 11, the guiding straight rod 16 is fixed to the lower end of the mounting plate 12, the lower end of the guiding straight rod 16 is inserted into the upper - end interior of the guiding sleeve 15, and multiple groups of the guiding components are respectively distributed at intervals.

[0034] In the above - mentioned embodiment, multiple groups of guiding components are connected between the mounting plate 12 and the bottom plate 11. During the process of the double - internal - thread pipe 13 rotating to make the mounting plate 12 move up and down relative to the bottom plate 11, the guiding straight rod 16 will move up and down relative to the guiding sleeve 15, ensuring that the mounting plate 12 will not be skewed during the up - and - down movement, remaining straight up and down and not rotating horizontally.

[0035] As a preferred embodiment, the clamping component 2 includes a rectangular frame body, an arc - shaped cushion block 21, two side - surface screws 22 and a top screw 23. The frame body is arranged vertically. The top screw 23 vertically penetrates the top wall of the frame body and is threadedly connected to each other. The two side - surface screws 22 respectively horizontally penetrate the two side walls of the frame body and are respectively threadedly connected to the side walls of the frame body. The arc - shaped cushion block 21 is installed at the upper end of the bottom wall of the frame body, and its arc - shaped opening faces upward. Clamping blocks 24 are respectively fixed to the mutually - approaching ends of the top screw 23 and the two side - surface screws 22.

[0036] In the above - mentioned embodiment, during clamping, one end of the long - distance pipeline passes through the frame body. The lower surface of the pipeline port is supported on the upper arc surface of the arc - shaped cushion block 21. The top screw 23 is screwed downward, so that the clamping block 24 at its lower end presses the upper part of the pipeline port. The two side - surface screws 22 rotate relatively closer, so that the clamping blocks 24 connected to them clamp the two sides of the long - distance pipeline port from both sides. In this way, the port of the long - distance pipeline is firmly clamped in the frame body. The centers of the frame bodies of the two groups of clamping components 2 are located on the same horizontal line and are parallel to the translation track (the straight line where it is located) of another group of clamping components 2.

[0037] It should be added that: the specifications of the two clamping components 2 are the same.

[0038] As a preferred embodiment, the above-mentioned translation mechanism includes a lead screw 32 and a slider 33. The lead screw 32 is horizontally arranged, and both ends thereof extend towards the two sets of clamping components 2 respectively. Both ends of the lead screw 32 are respectively assembled on the upper end of the base 1 through seat blocks 31 rotatably connected thereto. A nut is provided inside the slider 33. The lead screw 32 passes through the nut and is screwed with each other. The other set of clamping components 2 is installed on the upper end of the slider 33.

[0039] In the above-mentioned implementation, by operating the rotation of the lead screw 32, the slider 33 can be moved relative to the longitudinal axis direction of the lead screw 32 (the bottom of the slider 33 approaches the mounting plate 12 or the upper end of the base 1, so that the slider 33 will not rotate along with the lead screw 32), thereby driving the clamping component 2 at the upper end of the slider 33 to move along the length direction of the lead screw 32 to approach or move away from one of the clamping components 2, realizing the movement and docking of another long-distance pipeline to one of the long-distance pipelines. The structure design of the translation mechanism is simple, the operation is relatively simple and convenient, and the operation is also relatively stable.

[0040] In this embodiment, on both sides of the lower end of the frame body of one of the clamping components 2, connecting plates one 4 are respectively provided at intervals, and are installed on the upper end of the base 1 through the connecting plates one 4. On both sides of the lower end of the frame body of the other clamping component 2, connecting plates two 5 are respectively provided at intervals. A sliding plate 6 is provided at the lower end of the slider 33. The two connecting plates two 5 are respectively connected and fixed to the upper end of the sliding plate 6. Both ends of the lead screw 32 respectively pass through the area between the connecting plates one 4 and the area between the two connecting plates two 5. The design of the connecting plates one 4 makes one set of clamping components 2 suspended above the upper end of the base 1, and the design of the connecting plates two 5 makes the other set of clamping components 2 suspended above the upper end of the base 1. The hollow areas between the two connecting plates one 4 and between the two connecting plates two 5 can enable both ends of the lead screw 32 to pass through. The whole structure enables the translation mechanism to maintain a compact installation layout with the two sets of clamping components 2, and will not affect the clamping and translation of the long-distance pipeline, and the space utilization is good.

[0041] In this embodiment, a guide block 61 is provided at the upper end of the sliding plate 6. A guide rod 62 parallel to the lead screw 32 is horizontally penetrated in the guide block 61. Both ends of the guide rod 62 are respectively connected and fixed to the upper end of the base 1 through connecting blocks 63. Among them, the design of the guide block 61 and the guide rod 62 enables the slider 33 to move along the guide rod 62, ensuring that the running track of the slider 33 is relatively stable, and finally realizing the coaxial docking of the ports of the two long-distance pipelines, effectively improving the stability and accuracy of the welding docking, and reducing the subsequent welding error.

[0042] In this embodiment, there are two sets of guide rods 62 and guide blocks 61, and the two sets of guide rods 62 are distributed on both sides of the lead screw 32.

[0043] In this embodiment, knobs 34 are respectively provided at both ends of the lead screw 32. By operating the knobs 34 to rotate, the lead screw 32 can be driven to rotate, and the operation is simple and convenient.
