[0080] As an embodiment of the present application, please refer to Figure 1 、 Figure 2 、 Figures 4 to 8 The rotating assembly 52 comprises:

[0081] The rotating sleeve 521 is connected with the fixed arc plate 42;

[0082] The rotating rod 522 is rotationally connected with the rotating sleeve 521 and connected with the connecting plate 53;

[0083] The arc groove 523 is arranged on the rotating rod 522, and the central angle of the arc groove 523 is 90 degrees;

[0084] The folding rod two 524 is connected with the rotating sleeve 521 at one end and rotationally connected with the arc groove 523 at the other end.

[0085] In the initial state, as shown in Figure 8 , the connecting plate 53 and the rotating plate 514 are at 90 degrees, and the overall length of the device is short, which is convenient for storage. Figure 1

[0086] When the pipe body 1 needs to be butt-jointed, the worker rotates the connecting plate 53 around the center axis of the rotating sleeve 521 by 90 degrees (i.e., to the state shown in Figure 1 During the rotation, the arc groove 523 moves along the folding rod two 524, which limits the maximum rotation angle of the connecting plate 53, and when the connecting plate 53 is rotated to the horizontal state, the folding rod two 524 supports and positions the connecting plate 53, avoiding continuous rotation of the connecting plate 53.

[0087] In this embodiment, the folding rod one 513 and the folding rod two 524 are made of high-strength materials and will not deform due to the gravity of the pipe body 1, such as high-strength steel, alloy steel, etc.

[0088] As an embodiment of the present application, please refer to Figure 1 , Figure 2 , Figures 4 to 6 The limiting component 56 comprises:

[0089] The fixed cylinder 561 is connected with the fixed arc 2, and the fixed cylinder 561 contains liquid.

[0090] The folding rod three 562 is connected with the abutting arc plate 512 at one end and is located inside the fixed cylinder 561 and is in sliding connection with the inner wall thereof, and the other end of the folding rod three 562 is provided with a piston ring one.

[0091] The hose 564 is in communication with the inside of the fixed cylinder 561 at one end.

[0092] The connecting pipe 565 is in communication with the inside of the other end of the hose 564.

[0093] The folding rod four 566 is connected with the fixed arc 2 at one end and is rotatably connected with the connecting pipe 565 at the other end.

[0094] The sliding rod four 563 is connected with the rotating plate 514 and is in sliding connection with the other end of the connecting pipe 565, and the other end of the sliding rod four 563 is provided with a piston ring two.

[0095] ​The abutting arc plate 512 drives the bending rod 562 to move. The bending rod 562 moves inside the fixed cylinder 561, squeezing the liquid inside the fixed cylinder 561. This causes the liquid inside the fixed cylinder 561 to enter the connecting pipe 565 through the hose 564. The change in the volume of the liquid inside the connecting pipe 565 causes the sliding rod 563 to move. The sliding rod 563 moves synchronously with the rotating plate 514. When the abutting arc plate 512 moves to abut against the outer wall of the horizontal pipe end of the pipe body 1, the rotating plate 514 and the sliding rod 563 stop moving synchronously. Since the liquid is incompressible, when the pipe body 1 to be installed is placed on the support roller 55, the sliding rod 563 can position and support the rotating plate 514, preventing the rotating plate 514 from moving under the gravity of the pipe body 1.

[0096] The force required to compress water depends on the degree of compression. Based on the compressibility of fluids, compressing 1% of water requires approximately 3120 psi (pounds per square inch), meaning that water is almost incompressible under normal conditions and requires very high pressure to significantly reduce its volume. In this embodiment, the pressure applied by the pipe body 1 is far less than the force required to compress water; therefore, the liquid used in this application is water, which is considered incompressible.

[0097] In this embodiment, the rotatable connection between the fourth folding rod 566 and the connecting pipe 565, the rotatable connection between the rotating plate 514 and the first folding rod 513, and the central axis of the rotating rod 522 are coaxially arranged.

[0098] As one embodiment of the present invention, please refer to Figures 1 to 6 The fixed arc plate 42 has a slanted arc block 6 on one side near the horizontal pipe end, and the other side of the fixed arc plate 42 has a slanted edge structure.

[0099] The inclined structure and inclined arc block 6 facilitate the fixing of the arc plate 42 to the installation end of the pipe body 1.

[0100] The working principle of this invention is as follows: In the initial state, the connecting plate 53 and the instruction manual are connected. Figure 1 The device is positioned at a 90-degree angle, and its overall length is relatively short, making it easy to store.

[0101] When the pipe body 1 needs to be connected, the fixing arc plate 42 is abutted against the installed end of the pipe body 1 and the fixing arc plate 42 is pressed. Under the squeezing force of the spring 43, the fixing arc plate 42 abuts against the outer wall of the installed end of the pipe body 1, thereby fixing the fixing arc 2 and constraining the pipe body 1 from three directions to ensure that the central axis of the fixing arc 2 and the central axis of the pipe body 1 are on the same horizontal straight line. The support plate 33 abuts against the ground. The worker rotates the fixing bolt 34 so that the fixing bolt 34 abuts against the sliding rod 32, fixing the folding cylinder 31, thereby fixing the fixing arc 2.

[0102] The worker rotates the connecting plate 53 around the central axis of the rotating sleeve 521 by 90 degrees (i.e., to the state shown in FIG. 5B), and in the process of rotation, the arc groove 523 moves along the second folding rod 524, which limits the maximum rotation angle of the connecting plate 53, and when the connecting plate 53 is rotated to the horizontal state, the second folding rod 524 supports and positions the connecting plate 53, avoiding continuous rotation of the connecting plate 53. Figure 1

[0103] The cylinder 511 drives the abutting arc plate 512 to move linearly, so that the abutting arc plate 512 moves to abut against the outer wall of the horizontal pipe end of the pipe body 1, and in the process of movement of the abutting arc plate 512, the first folding rod 513 is synchronously driven to move, and the first folding rod 513 synchronously drives the rotating plate 514 to move, and the rotating plate 514 extrudes one end of the third sliding rod 54, so that the third sliding rod 54 drives the supporting roller 55 to move, and the second spring 515 is deformed, and when the abutting arc plate 512 moves to abut against the outer wall of the horizontal pipe end of the pipe body 1, the cylinder 511 stops working, and the abutting arc plate 512 cannot continue to move, at this time, the distance between the two supporting rollers 55 and the central axis of the pipe body 1 is equal to the outer diameter of the horizontal pipe end of the pipe body 1, that is, when the horizontal pipe end of the pipe body 1 to be installed is placed on the supporting roller 55, the outer wall of the horizontal pipe end of the pipe body 1 to be installed abuts against the supporting roller 55, and the central axis of the pipe body 1 is on the same horizontal line.

[0104] In the process of movement of the abutting arc plate 512, the third folding rod 562 is driven to move, and the third folding rod 562 moves in the fixed cylinder 561 to extrude the liquid in the fixed cylinder 561, so that the liquid in the fixed cylinder 561 enters the connecting pipe 565 through the hose 564, and the volume change of the liquid in the connecting pipe 565 drives the fourth sliding rod 563 to move, and the fourth sliding rod 563 synchronously moves with the rotating plate 514, and when the abutting arc plate 512 moves to abut against the outer wall of the horizontal pipe end of the pipe body 1, the rotating plate 514 and the fourth sliding rod 563 synchronously stop moving.

[0105] The worker uses a crane or the like to lift the pipe body 1 and place it on the supporting roller 55, at this time, the pipe body 1 to be installed is concentric with the installed pipe body 1, and because the liquid is incompressible, after the pipe body 1 to be installed is placed on the supporting roller 55, the fourth sliding rod 563 can support and position the rotating plate 514, avoiding movement of the rotating plate 514 under the action of gravity of the pipe body 1, and then the worker uses an excavator or the like to push the pipe body 1 to be installed, and pushes the horizontal pipe end of the pipe body 1 to be installed into the installation end, so as to install the pipe body 1.
