locking unit I on coupling push mechanism 3-1 opens: the piston rod of the locking hydraulic cylinder 3-1-7 extends out, the locking state is eliminated, the piston rod of the locking arm hydraulic cylinder 3-1-3 at one side with the locking hydraulic cylinder retracts to drive the locking arm 3-1-4 to rotate around a hinge point and open, then the piston rod of the locking arm hydraulic cylinder 3-1-3 at the other side retracts to drive the locking arm 3-1-4 at the other side to rotate around the hinge point and open, the pipe joint locking device on the pipe joint supporting mechanism is opened by adopting the same method, and the opening of the locking device is realized in the whole process as shown in figure 10; the pipe joint is placed on a moving seat 3-1-2 of a pipe joint pushing mechanism 3-1, and the whole pipe joint is supported by the pipe joint pushing mechanism 3-1 and a pipe joint supporting mechanism 3-3; the pipe joint is locked by a locking unit I on the pipe joint pushing mechanism 3-1: a piston rod of a hydraulic cylinder 3-1-3 of a locking arm at one side with a groove 3-1-4a extends out, the locking arm is pushed to rotate around a hinge point of the locking arm to embrace the pipe joint, the piston rod of the hydraulic cylinder at the other side extends out, the locking arm at the other side is pushed to rotate around the hinge point of the locking arm to embrace the pipe joint, the piston rod of the hydraulic cylinder 3-1-7 falls into the groove 3-1-4a on the locking arm, the piston rod of the hydraulic cylinder is retracted to embrace the pipe joint with certain pressure, and a lock head 3-1-7b is clamped in the groove 3-1-4a to lock the pipe joint; after the pipe joint is locked, the pipeline transportation engineering truck transports the pipe joint to the front of a butt-joint engineering truck, and the pipe joint is a pipe joint to be welded.
The process of delivering the pipe sections from the pipe conveying vehicle to the pipe aligning vehicle is as follows:
the pipeline transportation engineering truck with the to-be-welded pipe joint arrives at the front end of the pipeline aligning engineering truck, and the to-be-welded pipe joint on the moving seat 3-1-2 is conveyed to the pipeline aligning engineering truck through the extension of a piston rod of a pushing hydraulic cylinder 3-1-1 in a pipe joint pushing mechanism 3-1; when the pipe joint to be welded cannot be conveyed to a moving seat of a pipe joint pushing mechanism of the pipeline opposite-opening engineering truck in one-time conveying, the pipe joint pushing mechanism 3-1 on the pipeline transportation engineering truck needs to convey for multiple times; the specific method for multiple conveying comprises the following steps: the pipe joint to be welded is arranged on the movable seat 3-1-2 and locked by the locking unit I on the movable seat, and the piston rod of the propulsion hydraulic cylinder 3-1-1 extends out to complete the first conveying of the pipe joint to be welded; then, a supporting hydraulic cylinder 3-2-1 of a pipe joint supporting mechanism 3-2 acts to support two groups of supporting seats 3-2-2, when the supporting seats 3-2-2 contact the pipe joints, the supporting hydraulic cylinder 3-2-1 stops acting, a locking device on the supporting seat 3-2-2 is locked, a locking device on a moving seat 3-1-2 is opened, a pushing hydraulic cylinder 3-1-1 of the pipe joint supporting mechanism 3-2 and a hydraulic cylinder 3-3-5 of a pipe joint supporting mechanism 3-3 act simultaneously to lift the pipe joints, and at the moment, the pipe joints are separated from the moving seat 3-1-2; then a piston rod of a pushing hydraulic cylinder 3-1-1 in the pipe joint pushing mechanism 3-1 retracts to drive the moving seat 3-1-2 to retreat to the original position. Then, under the action of a pushing hydraulic cylinder 3-1-1, the pipe joint supporting mechanism 3-2 and the pipe joint bearing mechanism 3-3 drive the pipe joint to fall down; when the pipe joint falls back to the movable seat 3-1-2, the locking unit I on the pipe joint pushing mechanism 3-1 is locked, the locking unit II on the pipe joint supporting mechanism 3-2 is unlocked, and the pipe joint supporting mechanism 3-2 continuously falls back to the original position under the action of the supporting hydraulic cylinder 3-2-1, so that the circulation of conveying the pipe joint is completed. The pipe joint conveying process of the pipeline transportation engineering truck is stopped until the pipe joint to be welded on the pipeline transportation engineering truck is conveyed to the moving seat of the pipe joint pushing mechanism on the pipeline butt-joint engineering truck and the locking device on the pipe joint pushing mechanism can lock the pipe joint. When the pipe joint pushing mechanism of the pipeline opposite-opening engineering truck locks the pipe joint to be welded, the locking device on the pipeline transportation engineering truck is completely opened, the pipe joint supporting mechanism 3-3 supports the pipe joint part remained on the pipeline transportation engineering truck, and the pipeline opposite-opening engineering truck completes the conveying of the next pipe joint.

a. when the pipe joint pushing device I of the pipeline transportation engineering truck deflects left and right relative to the pipe joint pushing device I of the pipeline opposite-opening engineering truck, left and right movement of the whole truck is achieved through differential motion of the tracks on the left side and the right side of the pipeline transportation engineering truck.
b. When the pipe joint pushing device I of the pipeline transportation engineering truck vertically deviates relative to the pipe joint pushing device I of the pipeline opposite engineering truck, lifting hydraulic cylinders I2-6 of the front and rear frame adjusting devices of the pipeline transportation engineering truck can be simultaneously actuated, and the pipe joint pushing device I3 can integrally move up and down.
c. When the pipe joint pushing device I3 of the pipeline transportation engineering vehicle is dislocated in a vertical plane relative to the pipe joint pushing device I of the pipeline opposite engineering vehicle, the pipe joint pushing device I3 of the pipeline transportation engineering vehicle needs to pitch back and forth in the vertical plane to adjust the relative position of the pipe joint pushing devices I of the two vehicles; if the pipe joint pushing device I of the pipeline transportation engineering truck is in a forward-pitching state, the extension length of a piston rod of a lifting hydraulic cylinder I2-6 in the front end frame adjusting device can be larger than that of a piston rod of a lifting hydraulic cylinder I2-6 in the rear end frame adjusting device; similarly, if the pipe joint pushing device I of the pipeline transportation engineering truck is in a forward-bending state, the extension length of a piston rod of the lifting hydraulic cylinder I2-6 in the front end frame adjusting device can be smaller than that of a piston rod of the lifting hydraulic cylinder I2-6 in the rear end frame adjusting device.

The working principle and the process of the crawler-type pipeline aligning trolley are as follows:
if the pipe joint to be welded is provided by the pipeline transportation engineering truck: when the pipe joint to be welded is conveyed to a moving seat of a pipe joint pushing device II by a pipeline transportation engineering truck, a locking unit I on the moving seat is locked, and a locking unit II on the pipeline transportation engineering truck is completely unlocked; then, pushing the pipe joint to enable the pipe joint to reach a welding station; the adjusting method is the same as the pipe joint aligning adjusting method described below when the pipe joints to be welded are transferred by the two vehicles and the posture of the pipe joint pushing device II of the pipe joint aligning engineering vehicle is adjusted in a matching manner;

When the pipe joints are pushed, the pipe joint pushing process is the same as the actions of all mechanisms in the pipe joint pushing process of the pipeline transportation engineering truck, and only the number and the positions of the pipe joint supporting mechanisms 3-2 are different.
When the pipe joint to be welded is aligned with the pipeline port, if the pipe joint to be welded needs to move transversely in the horizontal plane, the transverse hydraulic cylinder 29 is controlled to jointly push the two trolley frames to move transversely, and the moving direction and the moving amount are the same, so that the trolley 21 and the pipe joint to be welded on the trolley 21 realize transverse translation; if the pipe joint to be welded needs to deflect in the horizontal plane, the transverse hydraulic cylinder 29 is controlled to respectively push the two small frames to move transversely, the respective moving direction and moving amount are determined according to the dislocation amount of the two pipe orifices, the change amount of two theoretical rotating center distances caused by asynchronous transverse movement of the two small frames is very small, the requirement can be met by the matching clearance of the mechanism, the shaft sleeve II 23 rotates relative to the upper sliding plate 25 due to different transverse positions of the two small frames, and the deflection of the small frame 21 and the pipe joint to be welded on the small frame in the horizontal plane is realized; if the pipe joint to be welded needs to move up and down in the vertical plane, the lifting hydraulic cylinder II 212 on the front side of the trolley and the rear side of the trolley are controlled to jointly stretch, and the stretching direction and the stretching amount are the same, so that the trolley 21 and the pipe joint to be welded on the trolley realize up and down movement; if the pipe joint to be welded needs to pitch back and forth in a vertical plane, the expansion and contraction of the lifting hydraulic cylinder II 212 in the two small vehicle frames are controlled, the expansion and contraction direction and the expansion and contraction amount are determined according to the dislocation amount of the two pipe orifices, the change amount of two theoretical wheelbases caused by the asynchronous height of the front and rear bearing shafts II 24 is very small, the requirement can be met by the fit clearance of the mechanism, the shaft sleeve II 23 rotates relative to the trolley 21 due to the different positions of the front and rear bearing shafts II 24 in the height direction, and the pitching of the trolley 21 and the pipe joint to be welded on the trolley in the vertical plane is realized; if the height of the tail pipeline end of the vehicle needs to be adjusted, a carrier roller lifting hydraulic cylinder II 3-3-5 in a pipe joint supporting mechanism 3-3 at the tail part of the vehicle body II is controlled to stretch, so that the height of the tail pipeline end of the vehicle is adjusted.
