[0034] 2. By designing a flip module, the flip module is used to flip the installation rod. The tubular prefabricated parts are hoisted by a tower crane during loading and unloading. The tubular prefabricated parts can be switched between a horizontal state and a vertical state through the flip module. During loading and unloading, the tubular prefabricated parts are in a vertical state. Compared with horizontal hoisting of tubular prefabricated parts, vertical hoisting can make the tubular prefabricated parts more evenly stressed, especially for thin-walled tubular prefabricated parts with a certain length. Vertical hoisting can avoid asymmetric stress on both ends during horizontal hoisting, resulting in extrusion damage inside the tubular prefabricated parts. After the hoisting is completed, the ladder tubular prefabricated parts are placed in a horizontal state through the flip module, and the ladder tubular prefabricated parts in a horizontal state are convenient for transportation by vehicles.

[0035] 3. By designing an end face restriction module, the end face restriction module is used to restrict the end face of the tubular preform. During transportation, the tubular preform will not shake significantly due to road bumps or turns, which protects the overall structure of the tubular preform. BRIEF DESCRIPTION OF THE DRAWINGS

In this embodiment, the third power member can be an electric telescopic cylinder or a hydraulic cylinder. In this embodiment, a pressure sensor is embedded in the elastic layer. When the electric telescopic cylinder or the hydraulic cylinder retracts to limit the end surface of the tubular preform 2, the pressure sensor detects the pressure change on the elastic layer. When the designed value is reached, the electric telescopic cylinder or the hydraulic cylinder stops retracting. This process can be detected and controlled by a control unit. The control unit can use a single-chip microcomputer or a plc control system. The single-chip microcomputer or the plc control system is used to detect the value of the pressure sensor. When the value of the pressure sensor reaches the set value, the electric telescopic cylinder or the hydraulic cylinder is driven to stop retracting. The relevant control program can be realized by a person skilled in the art through simple programming, which will not be repeated here. The electromagnet is controlled on and off by the same control unit. When powered on, it generates magnetism, adsorbs the limiting protrusion 7131, and causes the limiting protrusion 7131 to shrink to the side of the third clamping member 713, thereby realizing the rotation of the third clamping member 713. After rotating to the required angle, the electromagnet is powered off, and the limiting protrusion 7131 extends out under the elastic force of the spring 12, so that the limiting protrusion 7131 is selectively inserted into the first limiting hole 111 or the second limiting hole 112 to complete the limiting.

[0076] In the initial state, the radial dimensions of the first radial support module 4 and the second radial support module 5 are at the minimum state; the limiting member 71 is in an inclined state, the electromagnet is powered off, the limiting protrusion 7131 extends out and inserts into the second limiting hole 112 under the elastic force of the spring 12, and the second clamping member 712 and the third clamping member 713 are in an extended state;

[0077] The vehicle body 1 is driven to the loading destination of the tubular preform 2, and the tubular preform 2 is tied up with a rope and lifted vertically; the installation rod 3 is transformed from a horizontal state to a vertical state by using the flip module 6; the radial dimensions of the first radial support module 4 and the second radial support module 5 are adjusted to the minimum state so that the tubular preform 2 can be inserted; the tubular preform 2 is slowly released to be inserted into the installation rod 3; after the tubular preform 2 is inserted into the installation rod 3, the radial dimensions of the first radial support module 4 and the second radial support module 5 are adjusted to abut against the inner surface of the tubular preform 2; the end surface of the tubular preform 2 is limited by the end surface limiting module 7; specifically, in the initial state, the limiting member 71 is In the inclined state, the limiting protrusion 7131 is located in the second limiting hole 112, the control electromagnet is energized, the limiting protrusion 7131 overcomes the elastic force of the spring 12 and retracts, at which time the winding mechanism releases the pull rope 72, and the pull rope 72 is slowly released under the action of the torque member 73, and at the same time the limiting member 71 rotates around the hinge, and when it rotates to the horizontal, the control electromagnet is de-energized, the limiting protrusion 7131 extends out and inserts into the first limiting hole 111 under the elastic force of the spring 12, so that the limiting member 71 is limited to a horizontal state, and then the third power member is controlled to retract, so that the first clamping member 711 abuts against the end face of the tubular preform 2; finally, the flip module 6 is used to transform the mounting rod 3 from a vertical state to a horizontal state.

[0078] During unloading, the turning module 6 is used to turn the mounting rod 3 from a horizontal state to a vertical state, the third power member is controlled to extend, and then the electromagnet is controlled to be energized, the limiting protrusion 7131 is retracted, and the winding mechanism tightens the pull rope 72. After the pull rope 72 is tightened, it overcomes the torque member 73 to make the limiting member 71 rotate around the hinge and change from a horizontal state to an inclined state. Finally, the tubular preform 2 is lifted away by the lifting device.
