The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Reference Figures 1 to 4 As shown, the present invention provides a conveying pipeline connecting device for grouting and plugging in long-distance tunnels, comprising: a connecting pipeline 1, a base 2, and a pull rod 3.

[0030] The connecting pipe 1 is coaxially arranged between the two conveying pipes 4 . The diameter of the conveying pipe is adapted to the diameter of the connecting pipe. The pipe opening of the conveying pipe 4 is fitted to the pipe opening of the conveying pipe 4 .

[0031] participate Figure 1As shown, the pipe mouth of the connecting pipe 1 and the pipe mouth of the conveying pipe 4 are respectively formed with a plurality of flanges a. The pipe mouth of the connecting pipe 1 is formed with a plurality of flanges a. A gap is formed between two adjacent flanges on the connecting pipe. The pipe mouth of the conveying pipe 4 is respectively formed with a plurality of flanges a. A gap is formed between two adjacent flanges on the conveying pipe. Moreover, the position of the gap between two adjacent flanges on the connecting pipe corresponds to the position of the gap between two adjacent flanges on the conveying pipe. The plurality of flanges a are spaced apart along the circumferential direction of the pipe mouth. Lock holes are respectively provided at opposite ends of the flanges a.

[0032] The pipe opening of the connecting pipe 1 and the pipe opening of the conveying pipe 4 are respectively formed with four flanges a. The four flanges a are arranged at equal intervals along the circumferential direction of the pipe opening.

[0033] There are multiple bases 2. The number of bases is adapted to the number of gaps between the flanges. The positions of the bases correspond to the positions of the gaps.

[0034] A plurality of bases 2 are arranged along the circumferential direction of the connecting pipe 1. The base is arranged in the middle of the connecting pipe. The base 2 is installed outside the connecting pipe 1. The base 2 is formed with a socket aligned with the gap between the two adjacent flanges a. Push rods 21 are slidably arranged at the opposite ends of the socket. A driving mechanism is installed on the base 2.

[0035] The pull rod 3 is movably arranged in the gap. One end of the pull rod 3 is flipably mounted on the push rod 21. The other end of the pull rod 3 is connected to a pressing plate 31. The opposite ends of the pressing plate 31 are respectively pressed against the side of the two adjacent flanges a of the pipe mouth of the conveying pipe 4 away from the connecting pipe 1. The opposite ends of the pressing plate 31 are respectively formed with locking rods 32. The locking rod 32 is detachably inserted into the locking holes of the flanges a of the conveying pipe 4 and the connecting pipe 1.

[0036] When inspection and maintenance are required, the driving mechanism drives the push rods 21 at the opposite ends of the base 2 to move backwards to push the locking rod 32 out of the locking hole, and then flips the pull rod 3 to separate the pipe opening of the connecting pipe 1 from the pipe opening of the conveying pipe 4.

[0037] When the inspection and maintenance are completed, the connecting pipe is coaxially arranged with the conveying pipe. The pull rod 3 is reversely turned over so that the pull rod is arranged in the gap, thereby aligning the locking rod on the pressing plate with the locking hole.

[0038] The driving mechanism drives the push rods 21 at opposite ends of the base 2 to move toward each other so that the locking rod 32 is inserted into the locking hole, so that the pipe opening of the connecting pipe is tightly pressed against the pipe opening of the conveying pipe.

[0039] As a preferred embodiment, two legs 11 are respectively installed on opposite sides of the connecting pipe 1. The connecting pipe is erected by the legs, which facilitates the installation and removal of the conveying pipe.

[0040] In this embodiment, see Figure 3 and Figure 4 As shown, the driving mechanism includes: a screw 221 , a driven bevel gear 222 , and a driving bevel gear 223 .

[0041] There are two screws. The two screws 221 are coaxially arranged. The two screws 221 are rotatably installed in the socket. A partition is arranged in the socket. The partition is provided with a through hole, and the middle part of the screw is rotatably inserted into the through hole of the partition.

[0042] In this embodiment, the socket is a polygonal hole, and the cross-section of the push rod 21 is adapted to the shape of the socket, so that the push rod can only slide along the axial direction of the socket.

[0043] A threaded hole is provided at one end of the push rod 21. The opposite ends of the two screw rods 221 are respectively screwed into the threaded holes of the two push rods 21. The opposite ends of the two screw rods 221 are respectively coaxially connected with driven bevel gears 222. The base 2 is provided with a through hole connected to the socket. A shaft rod 224 is rotatably passed through the through hole. The driving bevel gear 223 is connected to one end of the shaft rod 224. The opposite sides of the driving bevel gear 223 are respectively meshed with the two driven bevel gears 222.

[0044] In this embodiment, the other end of the shaft 224 extends to the outside of the base 2 and is connected to a first hand wheel 225 .

[0045] See also Figure 1 and Figure 2 As shown, the other end of the push rod 21 is flipably mounted on one end of the pull rod 3 via a hinge shaft 211 .

The front and back sides of the middle part of the connecting pipe, as well as the top and bottom sides are fixedly connected with a base. The setting of the support leg plays a role in supporting the connecting pipe, and the setting of the disassembly device facilitates the disassembly and installation of the flanges, making the inspection and maintenance of the pipeline faster and simpler, reducing the physical exertion and work intensity of the operator, making the maintenance work easier and safer, and at the same time greatly shortening the time of disassembly and installation, and improving the maintenance efficiency.

The rotation of the first hand wheel facilitates the shaft rod to rotate, and the rotation of the shaft rod facilitates the active bevel gear to rotate.

[0050] The surface of the active bevel gear meshes with the driven bevel gear, one side of the driven bevel gear is fixedly connected with a screw rod, and the surface of the screw rod is threadedly connected with a push rod. The rotation of the active bevel gear can easily drive the driven bevel gear to rotate, and the rotation of the driven bevel gear can easily drive the screw rod to rotate, and the rotation of the screw rod can easily drive the push rod to move.
