[0046] Specifically, the linkage block 316 is rotatably connected to the adjustment ball 315, so that one end of the self-locking telescopic rod 326 is in a rotatable state, and the other end of the self-locking telescopic rod 326 is in a rotatable state by using the first hinge seat 325, so that the pipe jacket 321 can freely clamp the first pipe 1 and the second pipe 2 near the port in the staggered position during use;

After the two groups of adjustment balls 315 coincide with the central axis of the reset ring 311, the ports of the first pipe 1 and the second pipe 2 are docked;

[0048] When the hand wheel 336 is rotated by the construction personnel, the screw rod 335 is driven to rotate synchronously, so that the linkage disk 333 moves upward along the radial direction of the screw rod 335 and is clamped on the top of the self-locking telescopic rod 326 by the locking groove 334. First, the end of the self-locking telescopic rod 326 is limited, and then the linkage disk 333 continues to rise to pry one end of the self-locking telescopic rod 326, so that the two groups of self-locking telescopic rods 326 use the pipe jacket 321 to bring the ports of the first pipe 1 and the second pipe 2 closer to each other, so as to be used for displacement and docking of the pipe ports in the misaligned state;

[0053] The working principle of the pipeline connection device for laying lines on a construction site proposed in the embodiment of the present invention is as follows:

[0054] When the linkage block 316 is rotatably connected to the adjusting ball 315, one end of the self-locking telescopic rod 326 is in a rotatable state, and the other end of the self-locking telescopic rod 326 is in a rotatable state by using the first hinge seat 325, so that the pipe jacket 321 can freely clamp the first pipe 1 and the second pipe 2 near the port in the staggered position during use;

[0055] After the screw 42 is loosened, the telescopic rod 41 is in a state where the length can be freely adjusted, and the pipe opening clamp 43 is clamped on the other side of the port of the first pipe 1 or the second pipe 2, and after the screw 42 is tightened, the stability of the clamping of the pipe jacket 321 and the first pipe 1 or the second pipe 2 is improved to prevent the pipe jacket 321 from falling off from the pipe during the stretching process;

[0056] The storage drum 318 is driven to rotate by the output end of the servo motor 319, so that the steel wire rope is stretched during the process of winding with the storage drum 318, and the linkage column 314 is stretched. In the process of resetting the position of the adjustment ball 315, the two groups of adjustment balls 315 are made to coincide with the central axis of the reset ring 311, and the ports of the first pipe 1 and the second pipe 2 are docked;

[0057] When the hand wheel 336 is rotated by the construction personnel, the screw rod 335 is driven to rotate synchronously, so that the linkage disk 333 moves upward along the radial direction of the screw rod 335 and is clamped on the top of the self-locking telescopic rod 326 by the locking groove 334. First, the end of the self-locking telescopic rod 326 is limited, and then the continuous rise of the linkage disk 333 pries one end of the self-locking telescopic rod 326, so that the two groups of self-locking telescopic rods 326 use the pipe jacket 321 to bring the ports of the first pipe 1 and the second pipe 2 closer to each other, which is used for displacement and docking of the pipe ports in the misaligned state;

[0058] The output end of the dual-axis motor 342 drives the screw 343 to rotate, so that the two sets of adjustment blocks 344 move up or down synchronously, which is used to drive the lifting and lowering of the two sets of inclined rods 347, so that the intersection of the two sets of inclined rods 347 can be used to locate the connection of pipes with different diameters, which is convenient for construction personnel to perform sealing construction on the located pipe interfaces.
