Description

Technical Field

[0001] This utility model belongs to the field of marine oil engineering, and in particular relates to a welding anti-deformation device for small-diameter pipe fitting protective plates. Background Technology

[0002] During the onshore construction of offshore oil platforms, numerous pipelines need to be prefabricated and welded, and many small-diameter pipe fittings require welded protective plates. Because the protective plate welding is carried out during the prefabrication stage, the welding sites are relatively concentrated.

[0003] Because the protective plate requires welding in all positions, and small-diameter pipes have small diameters and thin walls, the heat is concentrated, making it very easy for welding the protective plate to cause deformation of the small-diameter pipes; deformation of small-diameter pipes will have a significant impact on their performance and quality.

[0004] Therefore, there is an urgent need to design a deformation prevention device for welding protective plates of small-diameter pipe fittings to solve the deformation problem of welding protective plates of small-diameter pipe fittings mentioned above. Utility Model Content

[0005] To address the technical problem mentioned in the background art, where small-diameter pipes have small diameters, thin walls, and concentrated heat, making them prone to deformation during welding of protective plates, a device for preventing deformation during welding of protective plates for small-diameter pipes is provided to solve the problem of deformation during welding of protective plates for small-diameter pipes.

[0006] To achieve the above objectives, the specific technical solution of the small-diameter pipe fitting protective plate welding anti-deformation device of this utility model is as follows:

[0007] A device for preventing deformation during welding of a small-diameter pipe fitting protective plate includes an operating platform. A first angle steel is connected to the operating platform, and a small-diameter pipe fitting is mounted on the first angle steel. A first fastening bolt is connected to the operating platform, fixing the small-diameter pipe fitting to the first angle steel. A channel steel is connected to the first angle steel, and a second angle steel is connected to the channel steel. The end of the small-diameter pipe fitting away from the first angle steel abuts against the second angle steel. A slide rail is connected to the channel steel, and a third angle steel is inserted into the slide rail. The third angle steel is connected to a shear jack, and a horizontal plate is connected to the shear jack. Second fastening bolts are spaced apart on the horizontal plate, and two second fastening bolts abut against the outer wall of the small-diameter pipe fitting at intervals to weld a protective plate onto the outer wall of the small-diameter pipe fitting between the two second fastening bolts.

[0008] Furthermore, the first angle steel is connected along the center line of the operating platform.

[0009] Furthermore, two first fastening bolts are connected to the operating platform, and the two first fastening bolts are located on both sides of the first angle steel.

[0010] Furthermore, each of the two first fastening bolts is hinged with a first washer plate. The first fastening bolts are adjusted so that the first washer plate abuts against the small-diameter pipe fitting.

[0011] Furthermore, a channel steel is connected along the center line of the operating platform, and a second angle steel is connected along the length of the channel steel, with the second angle steel having the same height as the first angle steel.

[0012] Furthermore, a slide is connected below the channel steel, and a third angle steel is inserted into the end of the slide away from the channel steel. The third angle steel slides along the length of the slide.

[0013] Furthermore, a shear jack is vertically connected below the third angle steel.

[0014] Furthermore, a horizontal plate is connected to the end of the shear jack furthest from the third angle steel, and second fastening bolts are symmetrically connected to the horizontal plate.

[0016] Furthermore, a second washer is hinged to the second fastening bolt. The second fastening bolt is adjusted so that the second washer abuts against the small-diameter pipe fitting.

[0017] The anti-deformation device for welding small-diameter pipe fitting protective plates of this utility model has the following advantages:

[0018] One end of the small-diameter pipe fitting is clamped to the first angle steel by the first fastening bolt, thus fixing the small-diameter pipe fitting. The other end of the small-diameter pipe fitting is fixed by the second fastening bolt.

Furthermore, by adjusting the second fastening bolts 6 and the shear jack 9, the welded part of the small-diameter pipe fitting 15 can be quickly fixed. This method is applicable to various pipe diameters and is convenient for construction personnel to operate.

[0032] Furthermore, such as Figure 1 As shown, a channel steel 7 is connected along the center line of the operating platform 1, and a second angle steel 3 is connected along the length of the channel steel 7.

Preferably, the channel steel 7 is welded to the operating platform 1 and located at one end of the first angle steel 2. A second angle steel 3 is welded inside the channel steel 7. The second angle steel 3 is at the same height as the first angle steel 2 so that the small-diameter pipe fitting 15 is placed horizontally on the first angle steel 2 and the second angle steel 3.

[0034] A slide rail 8 is welded to the lower end of the channel steel 7. The slide rail 8 is located on the same straight line as the channel steel 7. A third angle steel 4 is slidably inserted at the end of the slide rail 8 away from the channel steel 7. The third angle steel 4 is slidably set along the length of the slide rail, and a shear jack 9 is vertically welded below the third angle steel 4. Preferably, the first angle steel 2, the second angle steel 3 and the third angle steel 4 are all V-shaped.

[0035] Furthermore, such as Figure 1 and Figure 3 As shown, the shear jack 9 is connected to a horizontal plate 10 at the end away from the third angle steel 4. The horizontal plate 10 is symmetrically connected to a second fastening bolt 6. Two screws 13 are symmetrically connected to the horizontal plate 10. A connecting rod 14 is screwed onto the screw 13. The end of the connecting rod 14 away from the screw 13 is connected to the second fastening bolt 6. A second pad 12 is hinged to the second fastening bolt 6. The second fastening bolt 6 is adjusted so that the second pad 12 abuts against the small-diameter pipe fitting 15.

[0042] Based on the anti-deformation device for welding the protective plate of small-diameter pipe fitting 15, this utility model uses a first fastening bolt 5 to clamp one end of the small-diameter pipe fitting 15 onto the first angle steel 2, thus fixing the small-diameter pipe fitting 15. The other end of the small-diameter pipe fitting 15 is fixed by a second fastening bolt 6.

This device is applicable to various pipe diameters and is easy for construction personnel to operate. This application is easy to assemble and disassemble, and fine adjustments can be made through the fastening bolts to ensure that the pipe fitting is subjected to uniform and reasonable force.
