Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, an auxiliary docking device for pre-buried pipelines in water conservancy projects includes: a hoisting support sleeve 1, with sliding conductors 2 slidably fitted at both ends of the hoisting support sleeve 1, and a hydraulic pull-type docking mechanism 3 fitted at the bottom of the sliding conductors 2 at both ends;

[0025] The hydraulic pull-type docking mechanism 3 includes a special-shaped plate 31, with grippers 6 movably fitted at both ends of the bottom of the special-shaped plate 31, and a hydraulic cylinder 7 fitted between the special-shaped plate 31 and the grippers 6.

[0026] Among them, a bidirectional hydraulic cylinder 4 is fixedly installed at the bottom of the hoisting support sliding sleeve 1. Both ends of the bidirectional hydraulic cylinder 4 are equipped with push rods, and the ends of the push rods are fixedly equipped with end plates 5. The bidirectional hydraulic cylinder 4 is fixedly equipped with the irregular plate 31 through the end plates 5.

[0027] Furthermore, the telescopic movement of the bidirectional hydraulic cylinder 4 enables the corresponding movement of the hydraulic pull-type docking mechanism 3, thereby achieving auxiliary docking of the pipeline. The bidirectional hydraulic cylinder 4 can be replaced by a unidirectional hydraulic cylinder to deal with situations where one end of the pipeline cannot be moved.

[0028] The irregular plate 31 has an integral first lug 32 at both ends of its top, and an integral second lug 61 on the outer wall of the gripper 6. The hydraulic cylinder 7 is movably engaged with the first lug 32 and the second lug 61 at both ends.

[0029] Furthermore, the irregular plate 31 and the gripper 6 are respectively provided with an integrated first lug 32 and a second lug 6, which, in cooperation with the hydraulic cylinder 7, ensures the stability of the connection and improves the docking accuracy.

[0030] The hydraulic cylinder 7 includes a housing and a piston rod. A shaft plate 71 is provided at the end of the housing away from the piston rod and at the end of the piston rod. A second shaft 72 is fitted on the shaft plate 71. Both ends of the hydraulic cylinder 7 are movably fitted with the first lug 32 and the second lug 61 through the second shaft 72.

A first shaft 33 is provided near the bottom end of the irregular plate 31. The gripper 6 has a first shaft hole 63 corresponding to the first shaft 33.

[0034] In use, the lifting support sleeve 1 needs to be coordinated with the lifting equipment to be lifted and placed between the pipes to be connected. Then, the extension movement of the hydraulic cylinder 7 causes its gripper 6 to firmly clamp the main body of the pipe. Then, the reset movement of the bidirectional hydraulic cylinder 4 causes its hydraulic pull-type docking mechanism 3 to move accordingly to achieve auxiliary docking of the pipes.
