Description

Technical Field

[0001] The utility model belongs to the technical field of pipe welding, and in particular relates to a pipe rapid welding device used in pipeline engineering. Background Art

[0002] Pipeline engineering is the construction of pipelines for transporting oil, natural gas and solid slurry, including pipeline line engineering, station engineering and pipeline ancillary engineering. Pipeline engineering also includes the supply of equipment and facilities in a broad sense. Pipes are the materials used to make pipe fittings. Different pipe fittings require different pipes. The quality of pipes directly determines the quality of pipe fittings. Construction projects, power plants, chemical plants, etc. use such pipes. In pipeline construction, the medium is transported through pipes. Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. There are many sources of energy for welding, including gas flame, arc, laser, electron beam, friction and ultrasonic. In addition to being used in factories, welding can also be carried out in a variety of environments, such as outdoors, underwater and in space. When pipes are used in pipeline construction, the transportation distance is not enough, so it is necessary to increase the length of the pipes for welding.

Since the pipes need to be rotated for welding, the pipes are currently mostly flipped by welding operators, which can easily lead to deviations in the docking after the pipes are flipped, thereby affecting the accuracy of pipe welding and causing leakage in the pipes.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0038] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0039] like Figures 1 to 6 As shown, a pipe rapid welding device for pipeline engineering provided by an embodiment of the utility model comprises a welding gun, and the device further comprises:

[0040] A fixed base 1, on which a dynamic support assembly 3 and a static support assembly 5 are mounted, and the dynamic support assembly 3 slides relative to the fixed base 1 through the adjustment assembly 2;

[0041] The flip assembly 4 is arranged on the dynamic support assembly 3, and the flip assembly 4 includes:

[0042] A bidirectional cylinder 41, a positioning plate 42 is fixedly mounted on the output shaft of the bidirectional cylinder 41, and the bidirectional cylinder 41 is fixedly mounted in the flip column 48 through a column;

[0043] A positioning block 44, the positioning block 44 is movably connected to the positioning plate 42 through a positioning plate 43;

[0044] The fixing block 45 is fixedly mounted in the flip column 48, and the positioning block 44 is slidably matched with the fixing block 45;

[0045] The rubber block 47 is connected to the fixing rod 46, and the fixing rod 46 is hinged to the positioning block 44;

[0046] The shaft end of the turning column 48 is connected to the turning motor 49 through a power shaft.

[0047] In the embodiment of the utility model, in actual application, the pipe is sleeved on the flip column 48, the two-way cylinder 41 drives the positioning disk 42 to rotate the positioning plate 43, and the positioning block 44 is moved by the force and pushes the rubber block 47 through the fixing rod 46, and the rubber block 47 is made to fit with the inner wall surfaces of the two pipes to support them. When the welding position of the pipe needs to be changed, the flip motor 49 is energized and the flip column 48 is rotated through the power shaft. Due to the force of the rubber block 47 fitting with the two pipes, the two pipes will rotate synchronously, thereby increasing the stability of the pipe when it is flipped, making it convenient for welders to weld the pipe.

[0048] By setting the flip assembly 4, the inner wall surfaces of the two welded pipes can be supported at the same time, so that the stability during welding is good, and the two welded pipes can be rotated synchronously, which is convenient for welding other positions of the pipes. The problem of deviation in pipe docking caused by workers flipping the pipes can be reduced, thereby reducing the probability of leakage after pipe welding and increasing the safety of pipes used in pipeline engineering construction.

[0049] like Figure 1 and Figure 6 As shown, as a further embodiment of the present invention, the adjustment component 2 includes:

[0050] The adjusting screw rod 22 is installed in the fixed base 1. The adjusting screw rod 22 and the adjusting nut 23 form a spiral pair transmission.

Due to the limitation of the positioning groove 451, the stability of the positioning block 44 during movement can be increased, and the effect of fitting the rubber block 47 to the inner wall surfaces of the two pipes is better.

[0061] like Figure 1 and Figure 6 As shown, the device also includes an auxiliary support assembly 7, and the auxiliary support assembly 7 includes:

[0062] A support nut 71, the support nut 71 and the adjusting screw rod 22 form a spiral pair transmission, and the support nut 71 is arranged in the long hole 12 opened on the fixed base 1;

[0067] In the embodiment of the utility model, in actual application, when the adjusting screw rod 22 is driven, the supporting nut 71 can also be moved, and then the stability of the pipe clamped by the dynamic supporting assembly 3 during movement can be increased by the auxiliary wheel 75.

[0068] like Figure 1 and Figure 6 As shown, the device further comprises an auxiliary support assembly 8 , which comprises a second hydraulic column 81 fixedly mounted on the fixed base 1 , and a welding seat 82 is fixedly mounted on the output shaft of the second hydraulic column 81 .
