[0001] The utility model belongs to the technical field of pipeline processing, and in particular relates to an integrated device for automatic pipeline welding detection. Background Art

[0002] During the manufacturing or repair process of metal pipes, the welding surface needs to be welded. The pipes need to be fixed during welding to ensure the accuracy of the welding points. After welding, the welding quality needs to be judged to prevent defects in the welding. Since visual inspection cannot determine the defects, it is necessary to use appropriate testing equipment to detect the welding points.

[0003] The patent specification with publication number CN215573066U discloses an integrated automatic pipeline welding inspection device, including a movable trolley, a traction rope, a detection host, a fixed support, a rotating motor, a movable bracket, and a detection probe.

DETAILED DESCRIPTION

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 4 As shown, an integrated equipment for automatic pipeline welding detection includes a welding part and a detection part. The detection part is used to detect the pipeline welded by the welding part. The welding part includes a base plate 1. A movable rail 2 is installed on one side of the base plate 1. A support frame 3 is installed on the upper part of the movable rail 2. The top of the support frame 3 is rotatably connected to a welding gun clamp 4. A welding gun 5 is clamped on the top of the welding gun clamp 4. Two pipe clamp assemblies 6 are provided on one side of the base plate 1. The two pipe clamp assemblies 6 are symmetrical on the left and right, and multiple pipe pressing pieces 7 are installed on the top. A pipe fitting 8 is clamped between each pipe clamp assembly 6 and each pipe pressing piece 7. The detection part is installed on the inner side of the pipe fitting 8. A control switch 9 is provided on one side of the top of the base plate 1. The control switch 9 is used to control the opening and closing states of the welding part and the detection part in an integrated manner.

[0025] It should be noted that the movable rail 2 includes side plates 21 fixedly connected to both sides of the top of the base plate 1, and two parallel guide rods 22 are fixedly connected between the two side plates 21. The middle of the two guide rods 22 is rotatably connected to a screw 23, and a drive motor 24 is installed at one end of the screw 23. The control switch 9 is electrically connected to the drive motor 24. The bottom of the support frame 3 is adapted to be slidably connected with the two guide rods 22, and the middle of the bottom is threadedly connected to the screw 23. Therefore, when the control switch 9 starts the drive motor 24, the support frame 3 can be driven to move on the movable rail 2, and the welding gun 5 clamped on the welding gun clamp 4 can be moved to the welding position. In particular, since the welding gun clamp 4 is rotatably connected to the support frame 3, the welding gun 5 can be used to weld the outside of pipes 8 of different diameters by rotating the welding gun clamp 4.

[0026] like Figure 1 and Figure 2 As shown, the pipe clamp assembly 6 includes a bottom clamp 61, the top of which is fixedly connected to a top clamp 62. The inner sides of the bottom clamp 61 and the top clamp 62 are U-shaped. The bottom side of the pipe 8 is in contact with the bottom clamps 61 on both sides. The tops of the top clamps 62 on the same side of the pipe 8 are fixedly connected to the cross bar 10. The pipe pressing piece 7 passes through the cross bar 10 and abuts against the top of the pipe 8.

[0027] When the bolt 71 is in the closed position, the bolt 72 is in the closed position, and the locking nut 73 is fixed on the locking nut 73 so that the bolt 72 can be locked.

[0028] It should be noted that, preferably, the bottom clamp 61 and the top clamp 62 are fixed by bolts, and there are three pipe clamp assemblies 6 on both sides of the pipe fitting 8, and they are evenly arranged along the axial center line of the pipe fitting 8, wherein the bottom clamp 61 is used to support the two sides of the bottom of the pipe fitting 8, the top clamp 62 is used to cooperate with the bottom clamp 61 to provide the maximum outer diameter of the clamped pipe fitting 8, and the pipe pressing member 7 is used to clamp the top end of the pipe fitting 8, thereby forming a stable clamping function for pipe fittings 8 of different diameters. When used in conjunction with the adjustable position welding gun 5, accurate welding of pipe fittings 8 of different outer diameters can be achieved under stable clamping.

[0029] like Figure 4 As shown, the detection part includes a central axis 11, a detection probe 12 is installed at one end of the central axis 11, three side rods 13 are rotatably connected on both sides of the central axis 11 along the circumferential side, a moving wheel 14 is installed between two adjacent side rods 13 parallel to the axis of the central axis 11, a driving motor 2 15 is installed on one side of the moving wheel 14, and the driving motor 2 15 is electrically connected to the control switch 9, a diameter adjustment block 16 is installed between each side rod 13 on one side of the central axis 11, a connecting piece 17 is movably connected between the diameter adjustment block 16 and the adjacent side rod 13, and a spring 18 is installed between the side away from the connecting piece 17 and the other side rod 13;

[0030] It should be noted that, since the side rods 13 installed on both sides of the central axis 11 are rotatable along their axial centerline directions, and a diameter adjusting block 16 with a spring 18 is installed on one side, when it is placed in the pipe 8, the three side rods 13 connected to the diameter adjusting block 16 will squeeze the connecting piece 17 to make the diameter adjusting block 16 slide on the central axis 11, thereby adjusting the detection diameter of the detection part to adapt to the detection of pipes 8 with different inner diameters. The moving wheel 14 includes two wheel bodies installed on the side rods 13 on both sides, and a transmission belt is installed between the two wheel bodies. The outer side of the wheel body is rollingly connected to the inner wall of the pipe 8; during detection, the control switch 9 controls each drive motor 15 so that the detection part can move in the pipe 8, which is convenient for the detection probe 12 to perform gap detection on the welding position to ensure the welding quality.

[0031] The control switch 9 includes a detection movement control key electrically connected to the drive motor 2 15, a welding movement control key electrically connected to the drive motor 1 24, and a direction control key for controlling the forward and reverse directions of the two drive motors. When in use, it realizes the control of the movement state of the movable rail 2 and the detection part. In particular, when the movable rail 2 is in the moving state, the detection part does not perform the control operation, and when the detection part moves, the movable rail 2 does not perform the movement control, so as to ensure that the detection is carried out only after the welding is completed, avoiding the high temperature in the welding state during the detection. Damage to the detection part.

[0032] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
