Embodiment 1, please refer to Figures 1-5 The present application provides a technical solution: a propeller assembly hoisting tool is described as follows.

[0021] It comprises a mounting plate 1, the top of which is provided with a hook 2; An adjusting mechanism 3 is arranged at the bottom of the mounting plate 1; A binding mechanism 4 is symmetrically arranged at the bottom of the adjusting mechanism 3; A protective belt 5 is arranged at the bottom of the binding mechanism 4; In use, the worker will blade of one blade in the binding mechanism 4, will be in the adjacent two blades of the blade on the protective belt 5, make the propeller blade in cross state, place the upper vertical blade in the hoisting equipment, the hook 2 is connected with the crane, move the hook 2 blade through external force, the adjusting mechanism 3 is convenient, adjust the angle of the blade after the blade is lifted and adjust the tightness of the binding mechanism 4, the protective belt 5 further protects the binding mechanism 4, avoids that the blade will directly fall off when falling off.

[0022] The adjusting mechanism 3 comprises: The telescopic rod 301 is uniformly arranged at the bottom of the mounting plate 1; The push plate 302 is installed at the bottom of the telescopic rod 301, and the top of the push plate 302 is rotatably connected with the bottom of the mounting plate 1; The rotating assembly 303 is installed at the bottom of the push plate 302.

[0023] The adjusting mechanism 3 further comprises: The lifting rope 304 is arranged at the bottom of the mounting plate 1, and the lifting rope 304 is symmetrically provided with two, and the bottom of the lifting rope 304 is provided with the mounting block 305, and the mounting block 305 is connected with the top of the binding mechanism 4.

[0024] When the blade is bound, the telescopic rod 301 drives the push plate 302 to move downward, so that the rotating assembly 303 wraps the lifting rope 304, thereby reducing the space between the lifting rope 304 and the restraint belt 404, so as to form a triangular binding state between the lifting rope 304 and the restraint belt 404, when the telescopic rod 301 drives the adjusting assembly to move downward, the free length of the lifting rope 304 is shortened, so that the lifting rope 304 is pulled tight by the rotating assembly 303 close to the blade, and is clamped on the surface of the blade, so as to strengthen the stability of the blade in the moving process, and when necessary, the rotation angle of the blade is further controlled by controlling the rotation of the lifting rope 304, and the flexibility of the blade installation is improved.

[0025] The binding mechanism 4 comprises; The clamping block 401 is symmetrically provided with two, and the clamping block 401 is installed at the bottom of the adjusting mechanism 3; The tightening assembly 402 is installed on the outer wall of the clamping block 401; The anti-skid assembly 403 is installed on the opposite side of the clamping block 401.

[0026] The binding mechanism 4 further comprises: The connecting shaft 405 is arranged on the outer wall of the clamping block 401 away from the tightening assembly 402, and the connecting shaft 405 is rotatably connected with the clamping block 401; The restraint belt 404 is connected to the inner wall of the tightening assembly 402 at one end, and connected to the outer wall of the connecting shaft 405 at the other end.

[0027] At the initial stage, the staff manually moves the clamping block 401 to the two ends of the propeller blade placed on the ground, so that the anti-skid assembly 403 in the clamping block 401 is clamped on the two sides of the blade. At this time, the restraint belt 404 is in a relaxed state, and the tightening assembly can freely adjust the length of the restraint belt 404. When the staff clamps the anti-skid assembly 403 at the narrow part of the blade close to the bearing end, the restraint belt 404 is wound around the blade, and then the tightening assembly 402 tightens the restraint belt 404 to fix the clamping block 401 on the blade. The restraint belt 404 automatically winds and tightens the blade, and cooperates with the lifting rope 304 to form a triangular rope buckle to clamp the blade in the rope buckle, and then the crane is used to lift the propeller. By adjusting the distance of the anti-skid assembly 403, propellers of different models can be lifted without manual winding. The propeller is clamped on the restraint belt 404 by automatic tightening, which speeds up the operation efficiency of the equipment. The anti-skid assembly 403 increases the friction between the blade and the restraint belt 404, and the pressure between the anti-skid assemblies 403 is increased by the tightening assembly 402, which further protects the blade and prevents it from falling off.

[0028] Embodiment 2, please refer to Figures 1-9 The present application provides a technical solution: on the basis of embodiment 1, the rotating assembly 303 comprises: The sleeve 3031 is installed on the inner wall of the push plate 302, and the outer wall of the sleeve 3031 is provided with a protrusion 3032 at the bottom. The connecting rod 3033 is symmetrically arranged at the bottom of the sleeve 3031.

[0029] The rotating assembly 303 further comprises: The limiting block 3034 is installed at the bottom of the connecting rod 3033, and the bottom of the limiting block 3034 is symmetrically provided with a sleeve hole 3035. The inner wall of the limiting block 3034 is sleeved with the outer wall of the lifting rope 304.

[0030] In use, the telescopic rod 301 drives the push plate 302 to move downward, so that the sleeve 3031 moves downward and stores the lifting rope 304 in the sleeve 3031, and at the same time, the lifting rope 304 is sleeved in the limiting block 3034, so that the top ends of the lifting rope 304 are close to each other, thereby forming a triangle between the lifting rope 304 and the restraint belt 404, and clamping on the surface of the blade. Through the connection of the limiting block 3034 and the lifting rope 304, when it is necessary to adjust the direction of the propeller, an external force is applied close to the protrusion 3032 on the outer wall of the sleeve 3031, so as to clamp and rotate, so that the limiting block 3034 drives the lifting rope 304 to rotate, thereby achieving the adjustment of the propeller.

[0031] The tightening assembly 402 comprises: A winding box 4021 installed on the outer wall of the clamping block 401 away from the connecting shaft 405, and connected with the binding belt 404; A sleeve 4022 installed on the outer wall of the winding box 4021; A telescopic column 4023 installed on the outer wall of the sleeve 4022 away from the clamping block 401.

[0032] The tightening assembly 402 further comprises: A pressing plate 4024 installed on the other end of the telescopic column 4023; A support rod 4025 uniformly arranged on the end of the pressing plate 4024 close to the sleeve 4022, and the outer wall of the support rod 4025 is sleeved with the inner wall of the sleeve 4022.

[0033] The tightening assembly 402 further comprises: A movable plate 4026 symmetrically arranged on the inner wall of the sleeve 4022, one end of the movable plate 4026 is rotationally connected with the inner wall of the sleeve 4022, the support rod 4025 is in contact with the movable plate 4026 on one side, and the movable plate 4026 is arranged in two rows in an inclined manner, and the binding belt 404 is wound into the winding box 4021 through the gap between the movable plates 4026; A spring 4027 arranged on the inner wall of the sleeve 4022 away from the support rod 4025, and the other end of the spring 4027 is connected with the outer wall of the movable plate 4026.

[0034] After the clamping block 401 sleeves the binding belt 404 on both ends of the blade, the motor drives the binding belt 404 to tighten and wind in the winding box 4021, the binding belt 404 contacts the movable plate 4026 during winding, the telescopic column 4023 drives the pressing plate 4024 to move away from the movable plate 4026, at this time, the movable plate 4026 is in a relaxed state to the binding belt 404, when the winding is completed, the telescopic column 4023 drives the support rod 4025 on the pressing plate 4024 to move close to and press the movable plate 4026, so that the two rows of movable plates 4026 move close to each other and press the binding belt 404, forming a clamping state, thereby further clamping the binding belt 404 to avoid its tripping.

[0035] The anti-skid assembly 403 comprises: A hydraulic column 4031 uniformly arranged on the inner wall of the clamping block 401; An arc-shaped rod 4032, the outer wall of the arc-shaped rod 4032 is connected with one end of the hydraulic column 4031, and one end of the arc-shaped rod 4032 is rotationally connected with the inner wall of the clamping block 401; The anti-skid plate 4033 is installed on the inner wall of the clamping block 401, and the outer wall of the anti-skid plate 4033 is in contact with the other end of the arc-shaped rod 4032.

[0036] When the clamping block 401 is in contact with the edges of the two ends of the spiral blade, the edges of the blade are in contact with the anti-skid plate 4033, which is made of rubber and deforms the edges of the blade to protect the edges of the blade from being deformed due to the heavy weight of the spiral blade. The anti-skid plate 4033 also increases the anti-skid property of the blade for the binding belt 404. The tighter the binding belt 404 is tightened by the tightening assembly 402, the greater the friction between the anti-skid plate 4033 and the blade. After the binding belt 404 is tightened, the hydraulic column 4031 extends to drive the arc-shaped rod 4032 to approach the outer wall of the anti-skid plate 4033, so that the anti-skid plate 4033 deforms and is more closely attached to the blade, increasing the contact area between the anti-skid plate 4033 and the blade, thereby increasing the friction and improving the safety of hoisting.

[0037] The specific working process is as follows: At the beginning, the staff manually moves the clamping block 401 to the two ends of the propeller blade placed on the ground, so that the anti-skid assembly 403 in the clamping block 401 is clamped on the two sides of the blade. At this time, the binding belt 404 is in a relaxed state, and the tightening assembly can freely adjust the length of the binding belt 404. When the staff clamps the anti-skid assembly 403 on the narrow part of the blade close to the bearing end, the binding belt 404 is wrapped around the blade, and then the tightening assembly 402 tightens the binding belt 404 to fix the clamping block 401 on the blade. The binding belt 404 automatically wraps and tightens the blade, and the binding belt 404 cooperates with the lifting rope 304 to form a triangular rope buckle to clamp the blade in the rope buckle, and then the crane is used to lift the propeller; When the blade is bound, the telescopic rod 301 drives the push plate 302 to move downward, so that the rotating assembly 303 wraps the lifting rope 304, thereby reducing the space between the lifting rope 304 and the binding belt 404, and forming a triangular binding state between the lifting rope 304 and the binding belt 404. When the telescopic rod 301 drives the adjusting assembly to move downward, the free length of the lifting rope 304 is shortened, so that the lifting rope 304 is tightened by the rotating assembly 303 close to the blade, and is clamped on the surface of the blade, thereby strengthening the stability of the blade during movement. When necessary, the rotation angle of the blade is further controlled by controlling the rotation of the lifting rope 304, thereby improving the flexibility of the blade installation. The protective belt 5 further protects the binding mechanism 4 to prevent the blade from falling directly when it falls off.

[0038] Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art and related fields without creative labor should belong to the protection scope of the present application.
