The power hydraulic unit 5 can also be implemented by other hydraulic structures. The hydraulic structure belongs to the common knowledge of technicians in this field. The technicians can select the appropriate hydraulic structure according to the actual situation. The power hydraulic unit 5 includes an engine, a hydraulic pump, a motor, a control valve group, a fuel tank, etc., and an oil filter is installed on the oil suction and return pipelines to purify the hydraulic oil. The oil filter can effectively minimize the impurities in the hydraulic oil, thereby improving the reliability and service life of the operation.

A hydraulic motor and a reducer are installed on the driving wheel. The crawler walking unit 4 is driven by a hydraulic motor. The structure of the crawler walking unit 4 can also adopt the structure of an existing crawler vehicle. The two crawler walking units 4 are respectively located on both sides of the frame 1, and the frame 1 is slidably connected to the left and right crawler walking units 4. The operator can realize crawler walking, jacking and transverse movement and other functions by operating the controller; the frame 1, the left and right crawler walking units 4, the jacking unit 2, the transverse movement unit 6 and the power hydraulic unit 5 form a crawler trolley. The crawler trolley uses four sets of jacking units 2 to adjust the height direction of the pipe parts 12 to be connected. The four sets of transverse movement units 3 drive the frame 1 to slide on the crawler walking unit 4 to adjust the left and right directions of the pipe parts 12 to be connected. The crawler trolley can also have a collision warning function;The frame 1 is provided with a stabilizing unit 6, which includes two conveying components 601 and two filling components 602. The two conveying components 601 and the two filling components 602 are respectively located on both sides of the frame 1.

The electric hydraulic push rods 60202 extend to drive the push plate 60201 to push the soil 13 to the bottom and both sides of the pipe fitting 12 to be connected. As the soil 13 at the bottom and both sides of the pipe fitting 12 to be connected accumulates, the accumulated soil 13 stabilizes the pipe fitting 12 to be connected, avoiding the pipe fitting 12 to be connected from moving after the jacking unit 2 is separated from the pipe fitting 12 to cause the connection failure, thereby improving the connection success rate and the installation success rate of the PCCP pipeline;When in use, first, the operator mechanically places the pipe component to be butted 12 between the jacking units 2, and then the operator uses the controller to make the crawler walking unit 4 carry the pipe component to be butted 12 to move toward the end of the butted pipe component, and make the pipe component to be butted 12 close to the butted pipe component, and stop the movement of the crawler walking unit 4 through the controller, and then the operator controls the transverse moving unit 3 through the controller to adjust the left and right positions between the pipe component to be butted 12 and the butted pipe component, so that the left and right positions of the pipe component to be butted 12 and the butted pipe component are aligned, and then the operator controls the jacking unit 2 through the controller to adjust The upper and lower positions of the butt joint pipe parts 12 and the butt joint pipe parts are adjusted to align the upper and lower positions of the butt joint pipe parts 12 and the butt joint pipe parts. After that, the operator controls the crawler walking unit 4 to move toward the butt joint pipe parts end through the controller, and at the same time controls the lifting unit 2 and the lateral moving unit 3 through the controller to fine-tune the left and right and upper and lower positions between the butt joint pipe parts 12 and the butt joint pipe parts, and inserts the butt joint pipe parts 12 into the butt joint pipe parts. The operator stops the crawler walking unit 4 through the controller, and then the operator starts the conveying assembly 601, and the conveying assembly 601 conveys the soil 13 to The two sides of the pipe member 12 to be butted are arranged, and the soil 13 is located between the filling assembly 602 and the pipe member 12 to be butted. After that, the operator stops the conveying assembly 601, starts the filling assembly 602, and the electric hydraulic push rod 60202 makes the push plate 60201 push the soil 13 to the bottom and both sides of the pipe member 12 to be butted. The electric hydraulic push rod 60202 contracts to make the push plate 60201 close to the frame 1. After that, the conveying assembly 601 is repeatedly started to make the conveying assembly 601 convey the soil 13, and the filling assembly 602 is repeatedly started to make the soil 13 accumulate at the bottom of the butted pipe member 12. and both sides to fix the pipe fittings 12 to be butted. After that, the operator shrinks the lifting unit 2 through the controller to separate the pipe fittings to be butted from the lifting unit 2. Finally, the operator drives the crawler walking unit 4 to drive the frame 1 away from the pipe fittings to be butted 12 through the controller to complete the butt joint of the pipe fittings 12 to be butted and the butt joint pipe fittings, that is, to complete the installation of the PCCP pipeline. The crawler-type PCCP pipeline installation trolley can also be used for the installation of small-diameter PCCP pipelines.
