[0023] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0024] 1. In the present invention, a first support frame, rollers, a second support frame and support rollers are provided. The device can be quickly translated by four rollers, which is convenient for rapid transportation. The overall height of the device can be quickly adjusted by a first hydraulic rod connected to the first support frame to adapt to installation positions of different heights. During use, the second support frame can cooperate with the support rollers to temporarily support the pipes to be connected, and the height of the pipes can be fine-tuned by a third hydraulic rod connected to the second support frame, thereby improving the application range of the device.

[0025] 2. In the present invention, a second movable frame, a movable rod, a spring rod, a limit frame, a slide frame and a rubber wheel are provided. In the initial state, the two second movable frames are separated from each other and the distance between them is relatively large. When docking, two sets of fourth hydraulic rods are used to push two correspondingly connected second movable frames closer to each other. When the two second movable frames are at the minimum distance, the angles between the four movable rods are all maintained at right angles. At this time, the four movable rods are distributed at equal angles with respect to the axis of the pipe clamped between the two second movable frames. Therefore, in conjunction with the four spring rods and the rubber wheels at the ends, the position of the clamped pipe can be corrected. The two sets of second movable frames cooperate with each other to ensure that the two docked pipes are maintained at the same horizontal height during docking, thereby improving the stability during docking.

[0026] 3. In the present invention, an adjusting belt is provided, each adjusting belt is connected to two movable pulleys and a tensioning wheel that can move within a certain range, and each adjusting belt cooperates with a driving wheel driven by a second motor. When the pipelines are docked, after the pipeline is clamped and positioned by the second movable frame, the first movable frame is pushed to translate by the second hydraulic rod. During this process, the adjusting belt will first contact the pipeline between the two first movable frames. When the pulley is continuously subjected to pressure, it will slide to both sides along the first guide groove and pull the adjusting belt to gradually fit the surface of the pipeline. At the same time, the tightened adjusting belt squeezes the tensioning wheel and then pushes the reset spring to compress. The elastic force generated by the compressed reset spring cooperates with the tensioning wheel to ensure the adjustment The joint belt maintains sufficient tension to adapt to pipes of different sizes. At this time, the two sets of adjustment belts relative to each other clamp the pipes. By starting the first motor to drive the adjusting screw to rotate, the slide can be pushed to translate along the guide rod, thereby quickly adjusting the distance between the two pipes. At the same time, when the bolt holes of the flanges of the two pipes need to be docked after the docking is completed, the second motor is started to drive the adjustment belt to rotate slowly, which can drive the pipes to rotate, thereby quickly adjusting the positions of the bolt holes of the flanges on the pipes. During the adjustment process, the rubber wheel rotates with the pipe, and with the freely rotating slide, the rubber wheel can automatically adjust the movement direction according to the movement state of the pipe, thereby reducing the resistance encountered during pipe adjustment.

In this process, the adjusting belt 19 clamps the pipeline and drives the pipeline to start translation synchronously until the two pipelines are docked with each other. When the flange bolt holes of the pipeline need to be adjusted, the second motor 20 is started to drive the driving wheel 18 to start rotating, thereby driving the correspondingly connected adjusting belt 19 to rotate synchronously, and synchronously driving the clamped pipeline to rotate until the flange bolt holes of the two pipelines remain one-to-one corresponding.
