Description

Technical Field

[0001] The utility model relates to the technical field of thermal pipeline installation, in particular to a thermal pipeline welding alignment device. Background Art

[0002] Thermal pipes are generally used to transport steam or hot water. When the medium is steam, its temperature can be as high as 200 degrees. When the medium is hot water, its temperature will generally not be lower than 95 degrees. Therefore, the medium transported by thermal pipes has certain safety risks due to high heat. If the pipeline leaks, it is easy to cause harm to people and objects around it, and it will also cause heat loss. Therefore, the quality of laying, docking and installation of thermal pipes needs to be strictly controlled to avoid leakage due to loose docking at the docking parts.

[0003] At present, the joints of thermal pipes are connected by welding, so the pipe mouth alignment before welding of thermal pipes needs to be strictly controlled within the design range to ensure that the joints are tightly connected without leakage. However, in order to meet the carrying capacity, conventional thermal pipes have larger pipe specifications, and the pipe mouth diameter is generally 30cm-50vm. The pipe is mainly seamless steel pipe, and the surface is wrapped with polyurethane rigid foam as insulation material. A single pipe is generally more than 6m, so the weight of the thermal pipe is very large, and it is laborious to manually align the pipe before welding, and the pipe alignment needs to be kept stable during the welding process.

[0004] Therefore, in order to address the problems that the thermal pipeline is heavy, it is difficult to use manual labor to align and stabilize the state during welding, and the manpower consumption is high, a thermal pipeline welding auxiliary alignment device can be designed to eliminate manual alignment work and reduce the difficulty of welding. Utility Model Content

[0005] In order to overcome the heavy weight of thermal pipelines, it is difficult to use manpower to align and stabilize the state during welding, which results in high manpower consumption.

[0006] The technical solution of the utility model is: a thermal pipeline welding alignment device, including a thermal pipeline composed of a seamless steel pipe and an insulation layer, a supporting component, an adjusting component, an alignment guide rod, and a locking component; the supporting component has a quarter-circle arc-shaped recess adapted to the outer wall of the seamless steel pipe and the outer wall of the port of the seamless steel pipe is tightly attached to the surface of the recess, two groups of supporting components are radially symmetrically arranged at the port of the same seamless steel pipe, an adjusting component is arranged between two transversely adjacent groups of supporting components on the seamless steel pipes with opposite ports, an alignment guide rod is inserted between the transversely adjacent supporting components, and a locking component is arranged between two radially adjacent groups of supporting components.

[0007] Preferably, the supporting assembly supports the portion of the thermal pipe port that is not covered by the insulation layer, and is used in conjunction with the alignment guide rod to accurately align the two adjacent pipe ports. The adjusting assembly can adjust the distance between two laterally adjacent supporting assemblies according to the size of the welding equipment or the needs of the working space. The locking assembly locks the supporting assembly after the lateral spacing is adjusted and fixes it to the soil layer of the pipe groove.

[0008] Preferably, the supporting assembly includes a supporting ring, a support, and a base plate; the supporting ring is an arc-shaped structure of a quarter circle, and two radially adjacent groups of supporting rings enclose an arc-shaped structure of a half circle that matches the seamless steel pipe. The lower end of the supporting ring is integrally connected with the support, and the lower end of the support is integrally connected with the base plate that is tightly attached to the bottom wall of the pipe groove. The two radially adjacent groups of supporting rings support the portion of the port of the seamless steel pipe that is not covered by the insulation layer, and stabilize the load by supporting the base plate and the support on the soil surface of the pipe groove, ensuring that there is sufficient working space below the pipeline interface for welding operations.

[0009] Preferably, the supporting assembly further comprises a cantilever frame and a primary alignment hole; a triangular cantilever frame extending outward is fixedly connected to the outer wall of the supporting ring, a primary alignment hole is provided in the cantilever frame, and an alignment guide rod is inserted between the inner sides of two laterally adjacent groups of primary alignment holes. After the alignment guide rod is inserted into the primary alignment hole, the laterally adjacent supporting assemblies are locked so that the two cannot slide relative to each other, thereby ensuring that the ports of the supported thermal pipes are in precisely aligned positions.

[0010] Preferably, the supporting assembly also includes a secondary alignment hole and a clamp; a secondary alignment hole adapted to the alignment guide rod is opened at the top of the supporting ring, and a clamp adapted to the alignment guide rod is fixedly mounted on the bottom plate, and the clamp is a tough stainless steel metal ring structure. When welding a general ordinary steel pipe, because there is no obstruction of the insulation layer, the alignment guide rod can be directly inserted into the secondary alignment hole, which also has the effect of locking the laterally adjacent supporting assemblies. When the supporting assembly is not in use, the alignment guide rod is clamped into the laterally adjacent clamp for storage.

[0011] Preferably, the adjustment component includes a sleeve and a screw; a sleeve is arranged between two laterally adjacent groups of supporting components, and screws are fixedly connected to the left and right ends of the base plate, and the sleeve is threadedly connected to the corresponding screws on the left and right sides. Before the supporting component is placed in the pipe groove, the sleeve can be turned to adjust the spacing of laterally adjacent supporting components according to the needs of the thermal pipeline welding space, so that they are supported at the appropriate position of the seamless steel pipe port. The spacing of laterally adjacent supporting components is the operating space for the welding operation.

[0012] Preferably, the locking assembly includes a pin hole and a bolt; a pin hole is opened in the support, and the two radially opposite supports are tightened and fixed by bolts inserted into the pin holes. When the supporting assembly needs to be retained in the pipe groove, the bolt is inserted into the pin hole to lock the radially adjacent supporting assemblies into an integral structure, thereby further improving the support stability of the thermal pipeline.

[0013] Preferably, the locking assembly also includes an anchor hole and an anchor rod; a longitudinally through-going anchor hole is opened on the surface of the base plate, and an anchor rod with a sharp bottom end inserted into the soil layer of the pipe groove is inserted into the anchor hole. After the supporting assembly is placed in a suitable position of the pipe groove, the anchor rod is inserted from the anchor hole and sunk into the soil layer by using a tool to lock the supporting assembly in the pipe groove to prevent the supporting assembly from shaking during welding.

[0014] Beneficial effects of the utility model:

[0015] 1. The supporting assembly and the alignment guide rod are used together to support the ports of the thermal pipes in the same way as the traditional pipe seats, while ensuring the accurate alignment of the two adjacent pipe ports and the quality of welding. During the welding process, no manpower is required to support the pipes and stabilize their positions, which is more labor-saving and reduces the difficulty of welding operations. The distance between the two laterally adjacent supporting assemblies can be adjusted according to the size of the welding equipment or the needs of the working space through the adjustment assembly. It is flexible to use. With the help of the locking assembly, the two radially adjacent supporting assemblies can be locked with each other and fixed on the soil layer of the pipe groove, preventing the thermal pipes from sliding during the welding process. After welding, the supporting assembly can be selectively removed or retained according to the actual situation;

[0016] 2. Through the two alignment holes of different heights on the supporting component, not only the thermal pipeline with insulation layer can be aligned, but also other pipelines of the same specification as the thermal pipeline can be aligned. It is flexible to use and has a wide range of applications.

[0017] 3. Use the clamp on the bottom plate to easily fix and store the alignment guide rod when it is not in use to avoid loss of parts. BRIEF DESCRIPTION OF THE DRAWINGS

The supporting component 3 supports the portion of the thermal pipeline port that is not covered by the insulation layer 2, and is used in conjunction with the alignment guide rod 5 to accurately align the two adjacent pipeline ports. The adjustment component 4 can adjust the distance between the two laterally adjacent supporting components 3 according to the size of the welding equipment or the needs of the working space. The locking component 6 locks the supporting component 3 after the lateral spacing is adjusted and fixes it on the soil layer of the pipe groove.

[0028] See also Figure 6-7In this embodiment, the supporting assembly 3 includes a supporting ring 301, a support 302, and a bottom plate 303; the supporting ring 301 is a quarter-circle arc structure, and two radially adjacent groups of supporting rings 301 enclose an arc structure of half a circle adapted to the seamless steel pipe 1, the lower end of the supporting ring 301 is integrally connected with the support 302, and the lower end of the support 302 is integrally connected with the bottom plate 303 close to the bottom wall of the pipe groove, and the supporting assembly 3 also includes a cantilever frame 304 and a primary alignment hole 305; a triangular cantilever frame 304 extending outward is fixedly connected to the outer wall of the supporting ring 301, and a primary alignment hole 305 is opened in the cantilever frame 304, and the alignment guide rod 5 is inserted between the inner sides of the two laterally adjacent groups of primary alignment holes 305, and the supporting assembly 3 also includes a secondary alignment hole 306 and a clamp 307; A secondary alignment hole 306 adapted to the alignment guide rod 5 is provided at the top of the support ring 301, and a clamp 307 adapted to the alignment guide rod 5 is fixedly installed on the bottom plate 303, and the clamp 307 is a stainless steel metal ring sheet structure with toughness. The adjustment component 4 includes a screw sleeve 401 and a screw rod 402; a screw sleeve 401 is provided between two groups of support components 3 adjacent to each other in the horizontal direction, and the left and right ends of the bottom plate 303 are fixedly connected with screw rods 402, and the screw sleeve 401 is threadedly connected with the screw rods 402 corresponding to the left and right sides, and the locking component 6 includes a pin hole 601 and a bolt 602; a pin hole 601 is provided in the support 302, and the two radially opposite supports 302 are tightened and fixed by bolts 602 inserted in the pin hole 601, and the locking component 6 also includes an anchor hole 603 and an anchor rod 604;A longitudinally through-going anchor hole 603 is provided on the surface of the bottom plate 303, and an anchor rod 604 with a sharp bottom end inserted into the soil layer of the pipe groove is inserted into the anchor hole 603. The two radially adjacent groups of support rings 301 support the portion of the end of the seamless steel pipe 1 that is not covered by the thermal insulation layer 2, and stably bear the load through the bottom plate 303 and the support 302 supported on the soil surface of the pipe groove, ensuring that there is sufficient working space below the pipeline interface for welding operations. After the alignment guide rod 5 is inserted into the primary alignment hole 305, the laterally adjacent supporting components 3 are locked, so that the two cannot slide relative to each other, ensuring that the port of the supported thermal pipeline is in a precisely aligned position. If welding is performed on a general ordinary steel pipe, because there is no obstruction of the thermal insulation layer 2, the alignment guide rod 5 can be directly inserted into the secondary alignment hole 306, which also serves to lock the laterally adjacent supporting components 3 The effect of the welding operation is determined. When the supporting assembly 3 is not in use, the alignment guide rod 5 is inserted into the laterally adjacent clamp 307 for storage. Before the supporting assembly 3 is placed in the pipe groove, according to the needs of the thermal pipeline welding space, the screw sleeve 401 can be turned to adjust the spacing of the laterally adjacent supporting assemblies 3, so that it is supported at the appropriate position of the end of the seamless steel pipe 1. The spacing of the laterally adjacent supporting assemblies 3 is the operating space for the welding operation. When the supporting assembly 3 needs to be retained in the pipe groove, the bolt 602 is inserted into the pin hole 601 to lock the radially adjacent supporting assemblies 3 into an integral structure, further improving the support stability of the thermal pipeline. After the supporting assembly 3 is placed in the appropriate position of the pipe groove, the anchor rod 604 is inserted from the anchor hole 603, and the tool is used to hit it into the soil layer to lock the supporting assembly 3 in the pipe groove to prevent the supporting assembly 3 from shaking during the welding process. ;

[0029] When working, the operator first turns the screw sleeve 401 to adjust the distance between two groups of laterally adjacent supporting components 3 to a suitable size, and then places the supporting components 3 at a suitable point in the pipe groove, and makes the laterally adjacent supporting components 3 butt to form a semicircular arc-shaped notch;

[0030] Then, the alignment guide rod 5 is inserted into the primary alignment hole 305, and the laterally adjacent support components 3 are locked so that the two cannot slide relative to each other. Then, the two groups of thermal pipes are moved into the pipe groove so that the part of the end of the seamless steel pipe 1 that is not covered by the insulation layer 2 falls into the semicircular arc-shaped recess formed by the support component 3, so that the ports of the two groups of thermal pipes move relative to each other, so that the port spacing meets the welding operation requirements;

[0031] Then, the pipe port is welded using welding equipment. After the welding is completed and the weld has formed sufficient strength, the alignment guide rod 5 is pulled out, and then the support components 3 supported on the port are separated in turn. While separating, the weld part is covered with insulation material. After the covering is completed, the support components 3 are completely removed, and the thermal pipeline falls on the bottom wall of the pipe groove;

[0032] When it is necessary to retain the supporting assembly 3 as the pipe seat structure of the thermal pipeline, first insert the anchor rod 604 from the anchor hole 603, and use a tool to hit it into the soil layer to lock the supporting assembly 3 in the pipe groove, and then insert the bolt 602 into the pin hole 601 to lock the radially adjacent supporting assemblies 3 into an integral structure.

[0033] Through the above steps, the supporting assembly 3 and the alignment guide rod 5 are used in combination to play the same supporting role as the traditional pipe seat for the port of the thermal pipe, while ensuring the accurate alignment of the two adjacent pipe ports to ensure the quality of welding. During the welding process, no manpower is required to support the pipe and stabilize its position, which is more labor-saving and reduces the difficulty of welding operations, so as to solve the problem that the thermal pipe is heavy, it is difficult to use manpower to align and stabilize the state during welding, and the manpower consumption is high.

[0034] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
