When the middle U-shaped groove 202 is turned upwards, the limiting bolt 213 removes the clamping notch 212, and the left U-shaped groove 2011 and the right U-shaped groove are turned upwards and folded at the upper left part and the upper right part of the middle U-shaped groove 202 by adjusting the position of the adjusting bolt 208119 relative to the arc-shaped guide hole 206. The material stripping transition plate and the abdicating notch 207 are matched, so that not only can the pipe rod be supported and guided on the lower pipe positioning platform when the pipe is arranged, but also the left U-shaped groove 201 and the right U-shaped groove 203 can be better supported when the pipe is folded upwards, and meanwhile, the left U-shaped groove 201, the right U-shaped groove 203 and the middle U-shaped groove 202 are positioned. Upturning folding can be realized through the manual work assistance of crane cooperation, and also can be realized through setting up suitable drive structure, the utility model discloses the emphasis is not in going up to turn over folding through what kind of mode, so do not do the detailed description.

Because the pipe pole is very long, then whole pipe pole conveyer is very long, at the in-process of transportation, wholly can occupy very long space for can't transport through the crane, need dismantle, reduce holistic length, just can transport, have very big inconvenience. By being designed to be foldable, the total length of the pipe conveying trough 2 can be reduced to about one third of the original length. Therefore, when the foldable trolley is required to be carried, the foldable trolley can be directly transported through a crane as long as the foldable trolley is folded, and convenience is brought to carrying.

During pipe feeding, a pipe rod is grabbed through a pipe rod grabbing hand 103 in the pipe feeding turnover mechanism, then the turnover oil cylinder 106 drives the rotating arm 102 to rotate, so that the pipe rod grabbing hand 103 is turned upwards, then the pipe rod falls to the pipe rod conveying groove 2 from the pipe rod grabbing hand 103, one end of the pipe rod is arranged on the pipe conveying trolley 19, and in an initial state, the pipe conveying trolley 19 is located at an initial end. Then, the control device drives the tube conveying driving device to drive the tube conveying trolley 19 to slide towards the terminal along the slide rail 31. When one end of the pipe rod, which is far away from the pipe conveying trolley 19, is abutted against the length positioning plate 9, the length of the pipe rod can be calculated through the movement stroke of the pipe conveying trolley 19 by the control device. After the length measurement of the pipe rod is completed, the pipe lifting oil cylinder 12 works, the piston part of the pipe lifting oil cylinder 12 rises until the arc-shaped placing groove 14 wraps the pipe rod, and the pipe rod is lifted. After the pipe rod is lifted, the pipe conveying trolley 19 continues to move forwards until the pipe rod is erected on the supporting guide wheel 11, and then the pipe lifting oil cylinder 12 retracts to the initial position. After the lifting oil cylinder 16 works to lift the pipe rod conveying groove 2 to incline to a certain angle, the pipe conveying trolley 19 continues to carry the pipe rod to move forwards for a short distance, and the pipe rod is gripped by the elevator. At this time, the driving device of the pipe conveying trolley 19 does not provide power any more, the elevator lifts, the pipe conveying trolley 19 can continue to move forwards because the pipe rod is acting force until the pipe conveying trolley 19 moves to the end position, the elevator lifts continuously, and the pipe rod is separated from the pipe conveying trolley 19, namely completely separated from the pipe rod conveying groove 2. Thus, the pipe installing operation is completed.

During pipe laying operation, the elevator unloads the pipe, the pipe conveying groove 2 is lifted to a certain inclination angle through the lifting oil cylinder 16, the pipe conveying trolley 19 is located at the end part close to the elevator, one end of the pipe is placed on the pipe conveying trolley 19, the pipe below the elevator is backwards moved, after the elevator reaches the lowest point, the pipe is loosened by the elevator, and one end of the pipe, which is far away from the pipe conveying trolley 19, is arranged on the supporting guide wheel 11. Then, the pipe conveying trolley 19 continuously drives the pipe rod to move backwards through the driving mechanism until the pipe rod moves backwards to the end part, the stripping oil cylinder 3 works, the stripping lifting plate 4 lifts the pipe rod, the pipe rod is separated from the pipe conveying trolley 19 and slides downwards along the inclined plane 28 to the stripping transition plate 5, the pipe rod then falls to the pipe rod auxiliary arm 120 through the stripping transition plate 5 and slides downwards along the pipe rod auxiliary arm 120 until the arc-shaped supporting gripper 122 falls into the pipe bent, and pipe laying operation is completed.
