The electric push rods 21 are shortened to drive the first crawler traction machine 22 to move downward, so that the spacing between the first crawler traction machine 22 and the second crawler traction machine 4 can be adjusted, thereby adapting to the traction operation of water supply pipes of different thicknesses. The four electric push rods 21 are fixedly connected to the supporting frame 1, and the two ends of the traction assembly 2 are fixedly connected to the supporting frame 1. The two sides are fixedly connected with an extrusion assembly 3, and the extrusion assembly 3 includes a connecting plate 31, which is fixedly connected to the first crawler traction machine 22. Two connecting strips 32 are fixedly connected below the connecting plate 31, and the same connecting shaft 33 is fixedly connected below the two connecting strips 32. The connecting shaft 33 slides in the oblique opening 8. The oblique opening 8 is opened to make the connecting shaft 33 move, and the movable plate 7 can be squeezed by the oblique opening 8 to generate movement, thereby changing the direction of the force. The extrusion assembly 3 is slidably connected in the oblique opening 8, and the oblique opening 8 is opened on the movable plate 7. One side of the movable plate 7 is fixedly connected with two support strips 9, and the four support strips 9 are fixed to the same limit assembly 5. The limiting assembly 5 comprises two transmission shafts 51, which are connected by a limiting belt 52. The transmission shaft 51 can rotate smoothly through the bearing to reduce the rotation resistance of the transmission shaft 51, and the transmission shaft 51 can realize the transmission of the limiting belt 52, so that the limiting belt 52 can limit and guide the water supply pipe during the traction process of the water supply pipe to avoid the deviation of the water supply pipe, and the limiting belt 52 can rotate with the traction of the water supply pipe to reduce the wear between the water supply pipe and the water supply pipe. The two transmission shafts 51 are rotatably connected to the support frame 53 through the bearing, and the support frame 53 is fixedly connected to the four support bars 9. The limiting assembly 5 is located between the traction assembly 2 and the first Between the two crawler tractors 4, the first crawler tractor 22 and the second crawler tractor 4 can be operated to transmit the water supply pipe, thereby ensuring the traction operation of the water supply pipe. Four guide assemblies 6 are fixedly connected above the second crawler tractor 4. The guide assembly 6 includes two guide sleeves 61. Each support bar 9 is slidably connected to the corresponding guide sleeve 61. The two guide sleeves 61 are fixedly connected to the support plate 62.

[0025] The working principle of the utility model is as follows: when the water supply pipe is towed, the water supply pipe is placed on the second crawler traction machine 4, and then the electric push rod 21 is controlled to shorten, the electric push rod 21 drives the first crawler traction machine 22 to move downward, so that the first crawler traction machine 22 is pressed on the water supply pipe, and the first crawler traction machine 22 also drives the connecting plate 31 to move downward, the connecting plate 31 drives the connecting strip 32 and the connecting shaft 33 to move downward, the connecting shaft 33 slides on the oblique mouth 8, and the connecting shaft 33 squeezes the movable plate 7 through the oblique mouth 8, so that the movable plate 7 drives the support strip 9 to move, and the support strip 9 drives the support frame 53 to move, so that the two limiting belts 52 are close to each other and fit on the water supply pipe. At this time, the first crawler traction machine 22 and the second crawler traction machine 4 can perform traction operations, and the limiting belt 52 can limit and guide the water supply pipe during the traction process of the water supply pipe.
