[0019] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the implementation mode of the present invention is further described in detail below with reference to the accompanying drawings.

[0020] like Figures 1 to 3As shown, the transport and hoisting device for laying pipelines of water conservancy and hydropower projects includes a hanger 1, a lifting ring 2 is centrally arranged on the top of the hanger 1, two symmetrical side brackets 4 are slidably arranged on the bottom of the hanger 1, and a clamping plate 3 is arranged on the corresponding side of the two side brackets 4. The clamping plate 3 is an arc-shaped plate structure, and a driving component for driving the two side brackets 4 to move closer or farther away is arranged at the bottom of the hanger 1; in this embodiment, the hook of the lifting equipment is hung on the top of the lifting ring 2 to lift and move the hanger 1, the driving component drives the two side brackets 4 to move away from each other to open the clamping plate 3, and then the hanger 1 is moved to make the clamping plate 3 correspond to the two sides of the middle part of the pipeline, and the driving component drives the two side brackets 4 to move closer to clamp the clamping plate 3 on the outside of the pipeline. At this time, the lifting equipment can lift and move the hanger 1 to lift the pipeline.

[0021] Among them, two groups of clamps 3 are clamped and fixed on both sides of the pipeline, which can stably clamp the pipeline and prevent it from slipping, thereby ensuring the safety of the lifting process; the clamps 3 can be directly clamped on both sides of the pipeline placed on the ground or in the transport vehicle bucket, and then the pipeline is lifted by lifting the hanger 1. There is no need to manually lift the pipeline to fix the pipeline, which reduces labor expenses and improves construction efficiency.

[0022] like Figure 1 and 2 As shown, the driving assembly 6 has a reducer 62 fixedly arranged at the bottom of the hanger 1, and the interior of the reducer 62 is equipped with a bidirectional lead screw 61 with two ends corresponding to the tops of the two side brackets 4 respectively, and the two ends of the bidirectional lead screw 61 have external threads with opposite spiral directions. The reducer 62 is equipped with a brake motor 63 for driving the bidirectional lead screw 61 to rotate, and the top of the side bracket 4 has an internal thread drive block 44 threadedly connected to the bidirectional lead screw 61, wherein the brake motor 63 outputs power to drive the bidirectional lead screw 61 to rotate through the reducer 62, and the bidirectional lead screw 61 drives the side bracket 4 to slide at the bottom of the hanger 1 through the threaded structure between the bidirectional lead screw 61 and the internal thread drive block 44. Since the two ends of the bidirectional lead screw 61 have external threads with opposite spiral directions, rotating the bidirectional lead screw 61 can drive the two side brackets 4 to move closer or farther away, thereby achieving clamping or releasing the pipeline.

[0023] A slide 43 is fixedly provided on the top of the side bracket 4, and a guide rod 13 is slidably provided inside the slide 43.
