Description

Technical Field

[0001] This utility model relates to the field of pipeline welding construction technology, and specifically to an auxiliary tool for pipeline hot melt welding. Background Technology

[0002] During pipe hot-melt welding, it is necessary to maintain the stability and precision of the pipe joint. Existing technology includes hot-melt butt welding machines to help align the pipe ends, improving the precision of the joint and the quality of the hot-melt weld. However, the main problems with current hot-melt butt welding machines include:

[0003] 1. It can only be applied to the connection of horizontal pipes. In actual construction, there is a great need for the connection of vertical pipes. The connection of vertical pipes is still done manually, which cannot guarantee the accuracy of the connection or the quality of subsequent welding.

[0004] 2. Current hot melt butt welding machines have a bulky overall structure and large size, making them inflexible in use. They include two load-bearing bases with guide rods between them to assist in horizontal butt welding, but this results in a complex overall structure and limited flexibility in use.

[0005] It is evident that current pipe fusion welding solutions still have room for improvement and should be optimized to enable the application of fusion welding machines on vertical pipes, improve compatibility, and simplify the structure of the machines for greater flexibility and ease of operation. Therefore, a more reasonable technical solution is needed to address the existing technical problems. Utility Model Content

[0006] To overcome at least one of the aforementioned defects, this utility model proposes an auxiliary tool for pipe hot-melt welding. By improving the structure of the hot-melt welding machine, it can be applied to the welding and butt joint of vertical pipes. At the same time, the structure is simplified, and the ease of use of the auxiliary tool is improved while ensuring the butt joint accuracy.

[0007] To achieve the above objectives, the auxiliary tool disclosed in this utility model can adopt the following technical solution:

[0008] An auxiliary tool for pipe hot-melt welding includes two clamping mechanisms for holding the pipe, and a guide mechanism is provided between the two clamping mechanisms to guide the clamping mechanisms to slide closer or further apart; each clamping mechanism includes a clamping seat with a clamping cavity formed thereon and a clamping liner provided inside the clamping cavity; the guide mechanism includes at least two guide holes provided on the clamping seat and a guide rod provided at each guide hole.

[0009] The aforementioned auxiliary tool uses a clamping mechanism to clamp the pipes to be connected and then connects them along a guide mechanism. Since the guide mechanism and the clamping seat are directly matched, it can be used for connecting vertical pipes, which can improve the flexibility of use, avoid manual connection operations, and improve the precision and reliability of pipe hot melt welding.

[0010] Furthermore, the clamping seat can adopt various designs, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the clamping seat includes a first clamping block and a second clamping block. One end of the first clamping block and the second clamping block are hinged together, and the other end of the first clamping block and the second clamping block are connected and locked or unlocked by a fastening mechanism. When adopting the above design, the first clamping block and the second clamping block can be constructed in a semi-circular shape, forming a semi-circular clamping cavity inside. The clamping liner inside the clamping cavity forms a groove for accommodating the pipe. When the first clamping block and the second clamping block are engaged, the groove clamps the steel pipe. The hinged design at one end of the first clamping block and the second clamping block facilitates clamping the pipe after opening and closing, while the other end is engaged by a fastening mechanism. After the first clamping block and the second clamping block clamp the pipe, the mechanism locks the pipe, and the locking is released after docking is completed.

[0011] Furthermore, the locking of the first and second clamping blocks can be achieved using various methods, and its structure is not limited to a single one. Here, we optimize the design and propose one feasible option: Locking holes are correspondingly provided between the first and second clamping blocks, and the tightening mechanism includes a locking bolt and a locking nut that fit into the locking holes. When using this method, the locking bolt passes through both the first and second clamping blocks, and the locking nut fits onto the locking bolt, with an anti-loosening structure provided. The anti-loosening structure can be achieved by using multiple locking nuts, or by using high-carbon anti-slip nuts.

[0012] Furthermore, the cooperation between the first and second clamping blocks can be used not only for the thermal fusion butt welding of longitudinal pipes but also for the thermal fusion butt welding of horizontal pipes. When used for horizontal pipes, a corresponding base needs to be connected. The specific solution is not limited to one option. Here, an optimization is proposed, and one feasible choice is suggested: the first or second clamping block is provided with an extension connecting part, which is used to connect a detachable horizontal support. When the above solution is adopted, the horizontal support and the extension connecting part are inserted into each other and can be disassembled to facilitate switching between vertical and horizontal pipes.

[0013] Furthermore, the extended connection can be constructed in various forms, and its structure is not uniquely limited. Here, we optimize and propose one feasible option: the extended connection includes a connecting pin. When using the above solution, the number of connecting pins on a single clamping mechanism is at least two.

[0014] Furthermore, the connection pins on the first and second clamping blocks can be implemented in various ways, and their structures are not limited to a single one. Here, we optimize the design and propose one feasible option: a connecting platform is provided on the first or second clamping block, one end of the connecting pin is fixed to the connecting platform, and the other end is used to engage with the horizontal support base. When the above solution is adopted, the connecting platform is integrally formed with the first or second clamping block.

[0015] Furthermore, to improve the stability of the clamping mechanism's movement along the guide mechanism, the structure at its interface with the guide mechanism can be adjusted. Here, optimization is proposed, and one feasible option is suggested: a guide sleeve is provided on the guide rod, and the guide sleeve is connected to the clamping seat. When adopting the above solution, the guide sleeve can be integrally formed with the clamping seat, or it can be connected to the clamping seat via fasteners.

[0016] Furthermore, the way the clamping seats travel along the drive shaft is not limited to a single method. Here, we propose one feasible option: a drive shaft is positioned between the two clamping seats, with one of the clamping seats connected to an operating wheel. The operating wheel engages with the drive shaft, causing the clamping seat to move along the drive shaft. In this scheme, the operating wheel can be a hand crank.

[0017] Furthermore, the drive shaft can be constructed in various forms, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the drive shaft includes a gear shaft, and the operating wheel meshes with the gear shaft. When adopting the above scheme, the drive shaft can have a polygonal structure.

[0018] Furthermore, various solutions can be adopted when setting the clamping liner. Here, we optimize and propose one feasible option: the clamping cavity is provided with a clamping groove, and the clamping liner is fitted and fixed into the clamping groove. When the above solution is adopted, the clamping liner is embedded in the clamping groove.

[0019] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this utility model include:

[0020] This invention, through structural adjustments, enables both longitudinal and horizontal pipe fusion welding, thereby expanding the tool's application scenarios, improving the efficiency of welding operations, and enhancing the precision of pipe welding. It also avoids the low precision and quality problems caused by manual operation. Attached Figure Description

[0029] Example

[0032] The clamping seat can adopt various designs, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the clamping seat includes a first clamping block 1 and a second clamping block 2. One end of the first clamping block 1 and the second clamping block 2 are hinged, and the other end of the first clamping block 1 and the second clamping block 2 are connected and locked or unlocked by a fastening mechanism. When the above design is adopted, the first clamping block 1 and the second clamping block 2 can be constructed as semicircles, forming a semicircular clamping cavity inside. The clamping liner 3 inside the clamping cavity forms a groove for accommodating the pipe. When the first clamping block 1 and the second clamping block 2 are correspondingly engaged, the groove clamps the steel pipe. The hinged design of one end of the first clamping block 1 and the second clamping block 2 facilitates clamping the pipe after opening and closing, while the other end is engaged by a fastening mechanism.

The anti-loosening structure can be achieved by setting multiple locking nuts 7, or by using high-carbon anti-slip nuts to achieve anti-loosening.

[0034] The cooperation between the first clamping block 1 and the second clamping block 2 can be used not only for the thermal fusion but also for the thermal fusion but also for the thermal fusion of horizontal pipes. When used for horizontal pipes, a corresponding base needs to be connected. The specific solution is not limited to one option. This embodiment optimizes the process and adopts one feasible choice: the first clamping block 1 or the second clamping block 2 is provided with an extension connecting part 5, which is used to connect a detachable horizontal support.

When the above solution is adopted, the connecting platform 9 is integrally formed with the first clamping block 1 or the second clamping block 2.

[0037] To improve the stability of the clamping mechanism as it moves along the guide mechanism, the structure at its interface with the guide mechanism can be adjusted. This embodiment optimizes the process and adopts one feasible option: a guide sleeve is provided on the guide rod 4, and the guide sleeve is connected to the clamping seat. When using the above solution, the guide sleeve can be integrally formed with the clamping seat, or it can be connected to the clamping seat via fasteners.

[0038] The way the clamping seats travel along the drive shaft 10 is not limited to a single method. This embodiment optimizes the process and adopts one feasible option: a drive shaft 10 is provided between the two clamping seats, and an operating wheel 8 is connected and engaged with one of the clamping seats. The operating wheel 8 engages with the drive shaft 10 and moves the clamping seat along the drive shaft 10. When the above solution is adopted, the operating wheel 8 can be a hand crank.

[0039] In some designs, the guide rod 4 can be used as the drive shaft 10.

[0040] The drive shaft 10 can be constructed in various forms, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the drive shaft 10 includes a gear shaft, and the operating wheel 8 cooperates with the gear shaft.
