Technical Field

[0001] The utility model relates to the technical field of pipeline welding, in particular to an auxiliary welding device for long-distance pipelines. Background Art

[0002] With the continuous development of my country's cities and the continuous transfer of population to cities, the supply of urban drinking water will be a social livelihood issue faced by every urban development. The production capacity of existing water plants cannot meet the demand, but the water sources are often located in areas far away from cities, with less industrial and living pollution and good ecological environment. The contradiction between the demand and supply of drinking water is becoming increasingly intensified, which requires long-distance pipelines to transport water to thousands of households.

[0003] Due to the long length of long-distance pipelines, they need to be butt-jointed and installed by welding. In order to prevent the long-distance pipelines from breaking at the welding joints during welding, butt-jointing is required. The existing method is to lift and fix them manually or by crane. There are situations where the heights of the pipes to be welded are different, and the gap between the pipe joints is not easy to adjust due to the lifting. At the same time, the shaking of the pipes makes it difficult to control the gap between the joints, which affects the welding efficiency and quality of the pipelines by the construction personnel. Summary of the invention

[0016] The beneficial effect is that since the bottom plate and the fixed block lift the pipeline, there is a height difference between the pipeline and the end that is not in contact with the fixed block.

DETAILED DESCRIPTION

[0027] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0028] like Figure 1-3As shown, a long-distance pipeline auxiliary welding device includes a base plate 1. In this embodiment, the base plate 1 is a rectangular block with a certain thickness. A fixed block 3, a sliding block 4, a connecting plate 6 and a power piece 8 are sequentially installed along the length direction of the base plate 1. The fixed block 3 and the connecting plate 6 are both fixedly installed on the base plate 1, and the sliding block 4 is slidingly installed on the base plate 1. The upper surface of the fixed block 3 is at the same height as the upper surface of the sliding block 4. The heights of the connecting plate 6 and the power piece 8 are less than the height of the fixed block 3. A threaded rod 7 is rotatably installed on the connecting plate 6. The length direction of the screw rod is parallel to the length direction of the base plate 1. The end of the threaded rod 7 that is away from the connecting plate 6 in the length direction is rotatably connected to the fixed block 3. The threaded rod 7 passes through the sliding block 4. A threaded hole is opened in the sliding block 4. The length direction of the threaded hole is parallel to the length direction of the screw rod. The threaded rod 7 is threadedly connected to the threaded hole. The end of the threaded rod 7 that is away from the fixed block 3 in the length direction is connected to the power piece 8 The output end of the power piece 8 is fixedly connected to the threaded rod 7, and the power piece 8 uses a motor. The motor drives the threaded rod 7 to rotate so that the sliding block 4 slides along the length direction of the threaded rod 7; a clamping ring 5 is fixedly connected to the end of the fixed block 3 and the sliding block 4 away from the bottom plate 1. The clamping ring 5 is used to clamp the pipe 0. When the pipe 0 needs to be welded, the two ends of the pipe 0 to be welded are respectively clamped in the clamping ring 5. The sliding block 4 rotates along the threaded rod 7 under the driving action of the motor so that the clamped pipe 0 slides along the length direction of the screw rod, thereby making the joint between the pipes 0 tighter. At the same time, the fixed block 3 and the sliding block 4 have the same height direction, which facilitates the alignment of the pipe 0 so that its center is in the same straight line, thereby improving the welding accuracy; a level bubble 2 is installed on the bottom plate 1. The level bubble 2 is used to detect whether the bottom plate 1 is in a horizontal state, thereby reducing the influence of the uneven heights of the two ends of the butt-jointed pipes on the welding quality.

[0029] Reference Figure 1 The clamping ring 5 includes an upper clamping ring 51 and a lower clamping ring 52. The lower clamping ring 52 is fixedly connected to the surface of the fixing block 3. The upper clamping ring 51 is installed above the lower clamping ring 52. The upper clamping ring 51 and the lower clamping ring 52 are both shells with a semicircular shape. The size of the shell matches the size of the pipe 0. The upper clamping ring 51 and the lower clamping ring 52 are fixedly installed with a clamping block 10. The clamping block 10 is installed at the opening of the upper clamping ring 51 and the lower clamping ring 52. A mounting hole is opened in the height direction of the clamping block 10, and a bolt is installed in the mounting hole 11. Bolt 11 fixes the upper clamping ring 51 and the lower clamping ring 52 through the connecting clamp block 10. After the pipe 0 is placed on the lower clamping ring 52, the pipe 0 is fixed through the connecting clamp block 10. Rubber pads 12 are installed on the inner walls of the upper clamping ring 51 and the lower clamping ring 52. Due to its high elasticity, the rubber pads 12 make the pipe 0 squeeze the rubber pads 12 when the clamp block 10 is connected. The rubber pads 12 are deformed to increase the friction strength between the pipe 0 and the clamping ring 5, thereby improving the connection strength between the clamping ring 5 and the pipe 0.

[0030] Reference Figure 1 and Figure 2 A plurality of lifting rods 14 are evenly installed at one end of the bottom plate 1 away from the fixed block 3. In the present embodiment, two groups of lifting rods 14 are installed, and the two groups of lifting rods 14 are arranged in parallel. Since the pipeline 0 has a certain weight, a hydraulic lifting rod 14 with a strong load-bearing capacity is used in the present embodiment; a mounting plate 16 is fixedly connected to one end of the lifting rod 14 facing the bottom plate 1, and a mounting hole is opened on the mounting plate. A mounting connecting bolt 17 is installed in the mounting hole. The lifting rod 14 and the bottom plate 1 are detachably connected by installing the connecting bolt 17, which is convenient for disassembly of the lifting rod 14 and reduces the space occupied during transportation; a mounting seat 15 is fixedly installed at one end of the lifting rod 14 away from the bottom plate 1. In the present embodiment, the mounting seat 15 uses a rectangular plate with a certain thickness. The mounting seat 15 increases the contact area between the lifting rod 14 and the ground, improves the stability of the lifting rod 14, and improves the overall stability of the welding device.

[0031] During the welding process of the pipeline 0, the laid pipeline 0 has a certain height due to the setting of the pier or other supporting devices, and whether the height of the bottom plate 1 matches the supporting height of the pipeline 0 will affect whether the pipeline 0 is in a horizontal state after the clamping ring 5 is clamped, thereby affecting the welding effect; in order to make the welding device and the pipeline 0 height uniform, refer to Figure 1 A laser pen 13 is installed at one end of the fixed block 3 facing away from the sliding block 4 and at one end of the sliding block 4 facing away from the fixed block 3. The laser pen 13 is set horizontally. The height of the welding device is calibrated by the laser emitted by the laser pen 13, and then the height of the lifting rod 14 is adjusted so that the overall height of the welding device matches the height of the pipe 0 to be welded.

[0032] In the present invention, before welding the pipe 0, it is determined whether the lifting rod 14 is needed. If the height of the bottom plate 1 can meet the welding height of the pipe 0 without the need for a lifting plate, the lifting rod 14 does not need to be installed. If the height of the bottom plate 1 itself cannot meet the welding requirements, the lifting rod 14 is installed on the bottom plate 1 and the welding device is placed in the welding position so that the lower clamping ring 525 is opposite to the pipe 0, and the height of the bottom plate 1 is lifted by the lifting rod 14 until the height of the welding device matches the height of the pipe 0 to be welded, and the laser emitted by the laser pen 13 is used for judgment, and then the level bubble 2 is used to judge whether the bottom plate 1 is horizontal, and the height of the lifting rod 14 is adjusted according to the display of the level bubble 2 so that the bottom plate 1 is in a horizontal state; after the overall height of the welding device and the level of the bottom plate 1 are adjusted, the pipe 0 is placed on the lower clamping ring 52, the upper clamping ring 51 is installed, and the pipe is connected by bolts 11. 0 is clamped and fixed; then the motor is started so that the sliding block 4 slides along the threaded rod 7 under the rotation of the threaded rod 7 so that the pipe 0 connected thereto slides until the pipes 0 to be welded are aligned with each other, and then the construction personnel weld the joint position of the pipe 0. Since the threaded rod 7 has a corresponding length, a certain distance is left between the sliding block 4 and the fixed block 3, which will not affect the welding of the construction personnel; after the welding is completed, the connection between the upper clamping ring 51 and the lower clamping ring 52 is removed, and the lifting rod 14 is adjusted so that the contact between the pipe 0 and the lower clamping ring 51 disappears, and then the welding device is transferred to the next welding position for welding, and the overall height of the welding device is adjusted to the level of the bottom plate 1, and the pipe 0 is clamped to continue welding; after the welding of all the pipes 0 is completed, the lifting rod 14 is removed for storage, the upper clamping ring 51 is removed for storage, and the bottom plate 1 is stored, waiting for the next use.
