[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0022] The embodiment of the present application provides an air duct docking device for pipeline repair, which solves the problem that traditional air duct docking devices are usually fixed in size, inconvenient to support on the ground, easily form gaps during use, and are inconvenient to install air ducts when the size and model vary greatly.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] The utility model discloses an air duct docking device for pipeline repair. Figure 1-4 As shown, it includes a docking platform 1, on which a ground overhead bracket 101 is provided. The device is designed with the ground overhead bracket 101 so that the docking platform 1 can be easily supported and suspended on the ground, thereby facilitating quick docking of the air duct.

[0025] A fixed pipe head 2 is provided on the top of the docking platform 1, and a movable pipe head 3 is movably connected to the bottom of the docking platform 1. A first anti-slip ring 201 is provided on the fixed pipe head 2, and a second anti-slip ring 301 is provided on the movable pipe head 3. The device utilizes the design of the fixed pipe head 2 and the movable pipe head 3 to facilitate docking of two sets of air ducts. The fixed pipe head 2 is used to dock the blower equipment end. Usually, the air duct model of the blower equipment end is fixed, so the size of the fixed pipe head 2 is fixed. The movable pipe head 3 is used to fix the air duct at the pipeline repair end. The movable pipe head 3 is easy to replace on the docking platform 1, so it is suitable for fixing air ducts at the pipeline repair end of different models. The design of the first anti-slip ring 201 and the second anti-slip ring 301 makes it difficult for the air duct to slip when fixed, and has good stability.

[0026] A replacement mechanism is provided between the docking platform 1 and the movable pipe head 3. The replacement mechanism includes a docking base 4 provided on the docking platform 1 and a clamping block 5 provided on the movable pipe head 3. The clamping block 5 is movably clamped in the interior of the docking base 4.

[0027] A locking hole 501 is provided on the clamping block 5, and a locking pin 6 is movably inserted into the interior of the docking base 4, and the locking pin 6 is movably clamped in the locking hole 501. In this device, the replacement mechanism has a simple structure, and it is easy to quickly replace the movable tube head 3 on the docking platform 1. When installing the movable tube head 3, the operation is convenient. The clamping block 5 is clamped into the interior of the docking base 4 and the locking pin 6 is inserted into the locking hole 501 to lock it.

[0028] A guide rod 601 is fixedly connected to the side wall of the docking base 4, and an adjustment platform 602 for providing support for the locking pin 6 is slidably connected to the guide rod 601. A baffle 603 is fixedly connected to the guide rod 601, and a screw rod 604 is threadedly connected to the baffle 603. The screw rod 604 is rotatably connected to the adjustment platform 602, and a rotating handle 605 is provided on the screw rod 604.

[0029] The position of the locking pin 6 is easy to adjust. When adjusting the position of the locking pin 6, the screw rod 604 can be directly rotated. The screw rod 604 can be used to conveniently drive the adjustment platform 602 to move along the guide rod 601, and then the locking pin 6 is driven to move through the adjustment platform 602, so that the connection and locking between the docking base 4 and the block 5 are convenient, and the subsequent disassembly is convenient, thereby making the disassembly and assembly of the movable pipe head 3 convenient.

[0030] A rubber pad 7 is movably connected between the docking base 4 and the clamping block 5. When the docking base 4 and the clamping block 5 are docked, the rubber pad 7 is squeezed to achieve interface sealing, ensuring good sealing of the air duct docking position.
