[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] With the rapid development of the power engineering field, the demand for the construction of long-distance submarine cables and ultra-high-voltage land cables is increasing daily. Due to limitations in the production equipment and transportation of cable manufacturers, the production of long-distance cables must adopt the method of welding intermediate conductor joints. Therefore, the quality of conductor welding directly affects the conductivity, mechanical strength, and long-term operational reliability of the product.

[0004] In existing technologies, the support devices commonly used for welding intermediate conductor joints are mostly fixed or have limited adjustment structures. These are difficult to adapt to conductors of different sizes and cross-sections, requiring frequent fixture changes or complex adjustments, resulting in low efficiency and inability to meet diverse production needs. Furthermore, the lack of effective adjustment and locking mechanisms during welding makes the conductor prone to displacement and wobble due to thermal deformation, vibration, or external forces. This severely affects weld alignment accuracy and fusion quality, leading to defects such as incomplete welds and misaligned welds, damaging the electrical and mechanical properties of the joint. Moreover, existing support devices cannot effectively handle the high heat of welding, are prone to overheating and deformation, increasing the difficulty of the welding operation and exacerbating localized overheating of the conductor, affecting material properties.

One end of the bottom horizontal transmission screw 14 extends beyond the horizontal fixed block 2 and is equipped with a handwheel 3 for manual operation and adjustment of the bottom horizontal transmission screw 14; the other end is flush with the horizontal fixed block 2 to maintain the compactness and alignment of the overall structure.

[0025] At least two sets of upper horizontal transmission components are provided, including upper horizontal transmission screw 13 and upper horizontal guide rod 12. Each set of upper horizontal transmission components is provided with conductor fixing component 1. The upper horizontal transmission screw 13 and the upper horizontal guide rod 12 are installed through the conductor fixing component 1. The conductor fixing component 1 moves horizontally along the front and back direction of the upper horizontal transmission screw 13.

[0026] Specifically, the upper horizontal guide rod 12 is bolted to the upper fixed block 4 to ensure that the guide rod remains in a fixed position when under force, avoiding the influence of vibration; the upper horizontal transmission screw 13 is bolted to the upper fixed block 4 to realize power transmission and reduce transmission loss; the upper horizontal transmission screw 13 is equipped with a handwheel 3 at its end, which allows the operator to make manual adjustments for precise control of transmission speed or fine-tuning of position, improving the overall ease of operation.

[0027] The vertical transmission assembly mainly consists of a vertical guide shaft 5 and an upper fixing block 4. The upper fixing block 4 is tightly fitted onto the vertical guide shaft. Bolts pass through the corresponding holes on the fixing block and the guide shaft, and nuts are used to limit the specific position of the upper fixing block 4 on the vertical guide shaft, ensuring stability and adjustability during the transmission process.

[0028] Specifically, a fastening screw is provided on the upper fixing block 4, and a fastening sleeve 7 and a compression spring 10 are sequentially fitted on the fastening screw. The fastening sleeve 7 is used to apply clamping force, while the compression spring 10 provides elastic support and buffering effect, which together enhance the fixing reliability and operation smoothness of the device.

[0029] The bottom horizontal drive screw 14 and the upper horizontal drive screw 13 are arranged perpendicularly to each other in space. The bottom horizontal guide rod 11 and the upper horizontal guide rod 12 are also arranged perpendicularly in space, which can support independent motion control and ensure the stability of the guiding process. The vertical drive assembly and the bottom horizontal drive screw 14 are connected by a connecting plate. By rotating the bottom horizontal drive screw 14, the vertical drive assembly can move laterally along the bottom horizontal guide rod 11; while by rotating the upper horizontal drive screw 13, the conductor fixing assembly 1 can move horizontally in the front-back direction, thereby completing multi-directional guiding and positioning.

[0030] like Figure 2 As shown, the conductor fixing assembly 1 includes a sliding block 103, a conductor fixing mold 102, and a top cover 101.

[0031] The top of the cover 101 is provided with an adjusting bolt 104, which is used to adjust the distance between the upper and lower ends of the conductor fixing mold 102 to ensure that it can accommodate the assembly of conductors of different sizes.

[0032] The working principle of this utility model: In use, by rotating the handwheel 3 of the bottom horizontal transmission screw 14, the vertical transmission assembly is driven to move laterally along the bottom horizontal guide rod 11, thereby positioning the conductor in the left and right directions; by rotating the handwheel 3 of the upper horizontal transmission screw 13, the conductor fixing assembly 1 is driven to move longitudinally along the upper horizontal guide rod 12, thereby adjusting the front and rear position of the conductor; after loosening the fastening nut 6 and sliding the upper fixing block 4 along the vertical guide shaft 5 to the target height, it is locked by the fastening screw, thereby achieving lifting and lowering positioning in the Z-axis direction.

[0033] The conductor is then placed into the conductor fixing mold 102, the upper cover 101 and the sliding block 103 are closed, and the groove is locked by the fastening bolt 108 to simultaneously fix the ends of the conductors on both sides to prevent welding vibration displacement.

[0034] During the welding process, cooling water is injected into the cooling water channel 106 from the inlet 105, flows through the conductor welding area and is discharged from the outlet 107, continuously dissipating welding heat, reducing the heat-affected zone, and avoiding conductor performance degradation and device thermal deformation.
