Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figure 1 and Figure 2 As shown, a boiler pipeline installation and docking device includes a connecting sleeve 1 and two boiler tubes 2. A positioning ring 3 is fixed inside the connecting sleeve 1. Both ends of the positioning ring 3 are symmetrically provided with installation grooves for installing the boiler tubes 2. A sealing ring 1 4 and a sealing ring 2 5 are provided inside the installation groove. The ends of the boiler tubes 2 are inserted into the installation grooves, and the sealing ring 1 4 and the sealing ring 2 5 are respectively located on the inner side and the outer side of the boiler tube 2. One end of the sealing ring 1 4 is provided with a chamfer.

[0019] The two boiler tubes 2 are installed in the installation grooves, and the sealing ring 1 4 and the sealing ring 2 5 can improve the sealing performance of the connection between the connecting sleeve 1 and the boiler tube 2 to prevent smoke leakage.

[0020] like Figure 1 and Figure 3 As shown, locating members for fixing to the outside of the boiler tube 2 are symmetrically provided at both ends of the connecting sleeve 1, and the locating members include two arc-shaped locating plates 6, and anti-slip pads 9 are provided on the inner sides of the locating plates 6, and a plurality of connecting rods 7 are fixedly connected between the locating plates 6 and the connecting sleeve 1, and ear plates 8 are symmetrically fixedly connected at both ends of the locating plates 6, and a through hole 1 is opened in the middle of the ear plate 8, and a bolt 10 is installed in the through hole 1, and a nut is installed on the bolt 10.

[0021] The bolt 10 is installed in the through hole 1 and the nut is tightened, so that the two ear plates 8 are close to each other, and then the two positioning plates 6 are close to each other, so that the two positioning plates 6 are clamped and fixed on the outside of the boiler tube 2, so as to realize the connection and fixation of the connecting sleeve 1 and the boiler tube 2.

[0022] A fixing block 11 is fixedly connected to the outer side of the positioning plate 6, a fixing block 12 12 corresponding to the position of the fixing block 11 is fixedly connected to the boiler tube 2, a screw rod 13 penetrating through the fixing block 12 is fixedly connected to the side of the fixing block 11 away from the connecting sleeve 1, a through hole 2 adapted to the screw rod 13 is opened on the fixing block 12, and a butterfly nut is connected to one end of the screw rod 13.

[0023] When installing the boiler tube 2 in the installation groove, the screw rod 13 is passed through the second through hole, and then the butterfly nut is gradually tightened, so that the end surface of the boiler tube 2 can abut against the inner bottom surface of the installation groove.

[0024] In specific use, the two boiler tubes 2 are installed in the installation groove, and the screw rod 13 is passed through the second through hole, and then the butterfly nut is gradually tightened so that the end surface of the boiler tube 2 abuts against the inner bottom surface of the installation groove, completing the connection between the connecting sleeve 1 and the boiler tube 2, and the bolt 10 is installed in the first through hole and the nut is tightened so that the two ear plates 8 are close to each other, and then the two positioning plates 6 are close to each other, prompting the two positioning plates 6 to be clamped and fixed on the outside of the boiler tube 2, so as to achieve the connection and fixation of the connecting sleeve 1 and the boiler tube 2.

[0025] When the boiler tube 2 needs to be disassembled, the nut and the butterfly nut are removed to separate the boiler tube 2 from the connecting sleeve 1. The disassembly is simple and convenient for later inspection and maintenance.
