Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Embodiment 1:

[0030] A clamp for hoisting water conservancy equipment, in order to facilitate the fixation of water conservancy equipment components of different shapes, such as Figures 1 to 5As shown, it includes a hanging frame 1, a lifting assembly is fixed at the bottom of the sliding holes 18 opened on both sides of the hanging frame 1, a clamping assembly is fixed between the two lifting assemblies, the clamping assembly includes a driving block 6 and a driving shaft 11, the two driving shafts 11 are rotatably connected to the bottom of the two driving blocks 6, and the top and bottom of the driving shaft 11 are rotatably connected to two groups of clamping arms 7, and the two opposite clamping arms 7 are rotatably connected through a connecting shaft 10;

[0031] When it is necessary to fix the hydraulic equipment element, the hydraulic equipment element is placed in the gap enclosed by multiple clamping arms 7. By adjusting the straight-line distance between the two drive shafts 11, the shape of the diamond structure of the multiple clamping arms 7 can be adjusted. When it is necessary to fix cylindrical or square hydraulic equipment elements, such as pipe joints and building templates, the diamond structure formed by multiple clamping arms 7 can be used to make the surface of each clamping arm 7 fit the outer wall of the cylindrical or square hydraulic equipment element, thereby achieving clamping and fixation of hydraulic equipment elements of different shapes.

[0032] In order to facilitate the lifting of hydraulic equipment components, such as Figures 1 to 5 As shown, the lifting assembly includes an intermediate plate 3 and an electric telescopic rod 16, the electric telescopic rod 16 is fixed to the bottom of the lifting frame 1 by bolts, and the intermediate plate 3 is fixed to the output end of the electric telescopic rod 16 by bolts, and the lifting assembly also includes an electric telescopic rod 2 17, the electric telescopic rod 2 17 is fixed to the outer wall of one side of the intermediate plate 3 by bolts, and the output end of the electric telescopic rod 2 17 is fixed to the outer wall of one side of the driving block 6;

[0033] By providing an electric telescopic rod 16, the middle plate 3 can be driven to move in the vertical direction, and the electric telescopic rod 2 17 can be used to drive the driving block 6 to move in the horizontal direction. In this embodiment, the number of electric telescopic rods 2 17 is preferably two groups. When the output ends of the two groups of electric telescopic rods 2 17 maintain synchronous extension and retraction, the diamond structure formed by the multiple groups of clamping arms 7 clamps and fixes the components of the water conservancy equipment.

[0034] In order to facilitate the support of the bottom of the hydraulic equipment components, such as Figures 1 to 5 As shown, the outer walls of both sides of the hanging frame 1 are fixed with sliding frames 9 by bolts, and the outer walls of the two sliding frames 9 are slidably connected with supporting members, and the supporting members include rollers 2, sliders 8 and support frames 12, the sliders 8 are slidably connected to the outer walls of the sliding frames 9, and the support frames 12 are fixed to the side walls of the sliders 8 by bolts, and the rollers 2 are rotatably connected between the inner walls of the two sides of the support frames 12;

[0035] When it is necessary to clamp and fix the water conservancy equipment components, first place the water conservancy equipment components on the ground. When the two support frames 12 are moved to both sides along the sliding frame 9 through the slider 8, the lifting frame 1 can be moved to the top of the water conservancy equipment components through the hook to cover the water conservancy equipment components. After the water conservancy equipment components are clamped and fixed by the clamping assembly, the electric telescopic rod 16 is used to drive the middle plate 3 to rise, so that the water conservancy equipment components clamped by the clamping assembly rise a certain distance and then separate from the ground. When the bottom of the water conservancy equipment component moves to the top of the support frame 12, the two support frames 12 are moved relative to each other. After the two support frames 12 are closed, the water conservancy equipment components are placed on the top of multiple rollers 2 using the electric telescopic rod 16. The rollers 2 can be used to support the bottom of the water conservancy equipment components to prevent the water conservancy equipment components from falling during the lifting process.

[0036] In order to facilitate the lifting of the hoisting frame 1, Figure 1 to Figure 2 As shown, a lifting lug 4 is welded on the top outer wall of the lifting frame 1, and a lifting hole 5 is opened on the surface of the lifting lug 4;

[0037] During lifting, the lifting hole 5 and the lifting hook are connected by a steel wire rope, so that the lifting frame 1 can be lifted by the lifting hook.

[0038] In order to facilitate the positioning of the two support frames 12, Figures 1 to 5 As shown, a pressing frame 14 is fixed to the bottom of the middle plate 3 by bolts, and a positioning column 15 is welded to the bottom of the pressing frame 14, and a limiting groove 13 matching the outer diameter of the positioning column 15 is opened on the top of the support frame 12;

[0039] When the two support frames 12 are closed, in order to ensure the stability between the two, when the electric telescopic rod 16 drives the middle plate 3 to move downward, the positioning column 15 fixed at the bottom of the pressing frame 14 is inserted into the inner wall of the limiting groove 13 opened at the top of the support frame 12, so as to limit the position between the two support frames 12 and avoid shaking of the two support frames 12 during the lifting process.

[0040] Working principle: when it is necessary to hoist the water conservancy equipment components, first place the water conservancy equipment components on the ground or on a carrier, then connect the lifting hole 5 and the hook with a wire rope, and use the hook to move the lifting frame 1 above the water conservancy equipment components, then pull the two support frames 12 to both sides, and the lifting frame 1 moves downward so that the water conservancy equipment components are placed inside the clamping assembly, and then use the electric telescopic rod 2 17 to drive the driving block 6 to move horizontally, so that the clamping assembly clamps and fixes the water conservancy equipment components, and then use the electric telescopic rod 1 16 to drive the middle plate 3 to move up a certain distance. When the bottom of the water conservancy equipment component moves above the support frame 12, the two support frames 12 are moved relative to each other and closed. Finally, the electric telescopic rod 1 16 drives the middle plate 3 to move downward again so that the water conservancy equipment components are moved onto multiple rollers 2, and at this time the positioning column 15 is inserted into the inner wall of the limit groove 13, so that the positioning column 15 is used to limit the position between the two support frames 12.

[0041] Embodiment 2:

[0042] A clamp for hoisting water conservancy equipment, such as Figure 6 As shown, in order to facilitate the movement of the support frame 12, this embodiment makes the following supplements on the basis of embodiment 1: the top outer wall of the support frame 12 is fixed with a limit frame 19 by bolts, and a pulling hole 20 is opened on the top of the limit frame 19;

[0043] When the two support frames 12 are closed, in order to ensure that the limit groove 13 and the positioning column 15 are in a vertically opposite position, the limit frame 19 can be used to limit the maximum distance that the support frame 12 can move inward, and the support frame 12 can be easily pulled or pushed through the pulling hole 20 and the limit frame 19.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
