[0002] In today's infrastructure construction field, the laying of water pipeline is very important, with the acceleration of urbanization and the increase of water resource allocation projects in remote areas, the laying range of water pipeline is continuously expanding, more and more projects involve complex terrain environment, and complex terrain environment covers mountainous area, hilly area, gully crisscross area and the like, so large crane is needed to cooperate with hoisting frame to hoist water pipeline.

[0003] The existing large crane hoists water pipeline through hoisting frame, the clamping mechanical arm and clamp of hoisting frame are flexibly stretched and bent in different directions to adapt to the different positions and postures of pipeline in complex terrain, so that the pipeline is clamped and fixed by opening and closing of clamping mechanical arm and clamp, and then the clamped and fixed pipeline can be hoisted to installation position by large crane, but after clamping and fixing the pipeline by mechanical arm and clamp, the position and angle of the pipeline need to be adjusted when two groups of pipelines are connected, and because the pipeline is clamped and fixed, there is great friction when the pipeline is adjusted and rotated due to the close clamping of mechanical arm and clamp, so the mechanical arm and clamp need to be loosened to loosen the pipeline, and in complex terrain environment, the loosened pipeline may be displaced, rolled or even slipped due to its own gravity or external small interference force during hoisting, greatly reducing safety.

[0026] Roller 8, the roller 8 is provided with several groups, and the several rollers 8 are rotatably connected to the surface of the first arc clamping plate 6 and the second arc clamping plate 7 through the rotating shaft.

[0027] The top of the moving block 4 is slidably connected with the sliding slot 10 opened in the adjusting frame 2 through the sliding block 9, the air cylinder 11 is arranged in the moving block 4, and the piston rod of the air cylinder 11 is movably penetrated through the hanging bracket 5 and then connected with the first arc clamping plate 6.

[0028] The guide rod 12 is connected to the bottom of the hanger 5, the first arc-shaped clamping plate 6 is slidably connected to the surface of the guide rod 12 through the slide rod 13, one end of the bottom of the guide rod 12 is connected to the second arc-shaped clamping plate 7, and the guide rod 12 can guide the moving direction of the first arc-shaped clamping plate 6, so that the first arc-shaped clamping plate 6 has good linearity and stability during movement and cannot deviate or shake.

[0029] The first arc-shaped clamping plate 6 and the second arc-shaped clamping plate 7 are provided with protective pads 14 on the surfaces, the protective pads 14 are made of soft and wear-resistant rubber material, and can prevent the water pipeline from being scratched and worn due to excessive clamping force or uneven clamping plate surface.

[0030] The motor 15 is arranged on one side of the surface of the adjusting frame 2, and the output shaft of the motor 15 is rotatably connected with the reversible screw rod 3.

[0031] The lifting lugs 16 are connected to the top of the lifting frame 1, the lifting blocks 18 are connected to the lifting lugs 16 through the cables 17, the lifting blocks 18 are used to be connected with the hooks of the crane, when the hooks of the crane lift the lifting blocks 18, the lifting frame 1 at the bottom of the lifting lugs 16 can be lifted through the cables 17, so that the water pipeline can be moved and lifted.

[0032] When the motor 15 is started, the output shaft of the motor 15 starts to rotate and transmits power to the reversible screw rod 3, the reversible screw rod 3 rotates at a predetermined speed and direction under the drive of the motor 15, the two groups of moving blocks 4 connected with the reversible screw rod 3 through the screw nut transmission are linearly moved in opposite directions under the rotation of the reversible screw rod 3, in this process, the sliding block 9 at the top of the moving block 4 stably and smoothly slides in the sliding groove 10 in the adjusting frame 2, the sliding mode effectively limits the movement track of the moving block 4, ensures that the moving block 4 can only move accurately along the direction of the sliding groove 10, so as to ensure the accuracy and stability of the movement of the moving block 4, and the interval between the two groups of moving blocks 4 can be adjusted to meet the adjustment of the clamping position of the water pipeline.
