[0001] The utility model relates to the technical field of horizontal hangers, in particular to a horizontal hanger for wind turbine blades. Background Art

[0002] A sling is a device used to lift heavy objects in a lifting machine. The most commonly used slings for lifting finished objects are hooks and slings. Others include lifting rings, lifting suction cups, clamps, and forks. They are widely used in the lifting and hoisting industry.

[0003] For lifting of wind turbine blades, vertical hoists are usually used for lifting operations. However, traditional vertical heavy hoists can only simply lift wind turbine blades, which is very cumbersome when fixing wind turbine blades of different models, and has poor stability.

[0004] For this purpose, we provide a horizontal lifting device for wind turbine blades. Utility Model Content

[0006] The utility model provides the following technical solution: a horizontal hanger for wind turbine blades, comprising a horizontal frame, the inner wall of the horizontal frame is fixedly connected to an inner frame, the top of the inner frame is fixedly installed with a connecting seat, both ends of the horizontal frame are fixedly connected to side plates, the interior of the horizontal frame is slidably clamped with a clamping block, the bottom end of the clamping block is fixedly connected to a hanger, the inner wall of the hanger is provided with a frame clamping strip, the side of the frame clamping strip is fixedly connected with a sliding rod 1, and the sliding rod 1 is slidably plugged with the side wall of the hanger.

[0007] Preferably, the bottom ends of both sides of the block are rotatably connected to rollers, the bottom end of the horizontal frame is fixedly connected to an inner edge strip, and the bottom ends of the rollers abut against the upper surface of the inner edge strip.

[0008] Preferably, a dual-axis motor is fixedly connected inside the inner frame, threaded rods are fixedly connected to both ends of the dual-axis motor, and the clamping block is threadedly sleeved on the surface of the threaded rod.

[0009] Preferably, an electric telescopic rod is fixedly connected to the side of the hanger, and one end of the electric telescopic rod is fixedly connected to the side of the frame clamp.

[0012] Preferably, a plug rod is slidably inserted into the side of the frame clamp, one end of the plug rod is fixedly connected to an end plate, and a threaded locking bolt is threadedly connected to the surface of the frame clamp, and the end of the threaded locking bolt fits with the surface of the plug rod.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By providing a double-axis motor, when hoisting the wind turbine blades, after starting the double-axis motor, the threaded rods at both ends of the double-axis motor will be driven to rotate, thereby driving the block to move inside the horizontal frame, and at the same time, the roller will slide on the upper surface of the inner edge strip, thereby driving the hanger to move accordingly. Since the two hangers move in different directions, the distance between the two hangers is consistent with the model of the wind turbine blades. Then the electric telescopic rod is started to drive the frame clamp to move. After the two frame clamps move in different directions, the wind turbine blades can be clamped and fixed, so that the wind turbine blades can be hoisted.

[0015] 2. By providing an end plate, when the device clamps and fixes the wind turbine blade, the insertion rod can be inserted into the side of the frame clamp, and the insertion rod can be slid inside the frame clamp so that the inner wall of the end plate abuts against the end of the wind turbine blade. After the inner wall of the end plate abuts against the end of the wind turbine blade, the threaded locking bolt is tightened so that the end of the threaded locking bolt fits with the surface of the insertion rod, increasing the friction with the surface of the insertion rod, thereby fixing the position of the end plate, thereby further fixing the position of the wind turbine blade, and effectively preventing the wind turbine blade from slipping.

[0022] The bottom ends of both sides of the clamping block 8 are rotatably connected to rollers 9 , the bottom end of the horizontal frame 1 is fixedly connected to an inner edge strip 7 , and the bottom ends of the rollers 9 abut against the upper surface of the inner edge strip 7 .

[0023] Among them, a dual-axis motor 5 is fixedly connected to the inside of the inner frame 2, and threaded rods 6 are fixedly connected to both ends of the dual-axis motor 5. The clamping block 8 is threadedly sleeved on the surface of the threaded rod 6. After starting the dual-axis motor 5, the threaded rods 6 at both ends of the dual-axis motor 5 will be driven to rotate, thereby driving the clamping block 8 to move inside the horizontal frame 1. At the same time, the roller 9 will slide on the upper surface of the inner edge strip 7, thereby driving the hanger 10 to move accordingly. Since the two hangers 10 move in different directions, the distance between the two hangers 10 is consistent with the model of the wind turbine blade.

[0024] Among them, an electric telescopic rod 14 is fixedly connected to the side of the hanger 10, and one end of the electric telescopic rod 14 is fixedly connected to the side of the frame clamp 12. The electric telescopic rod 14 is started to drive the frame clamp 12 to move. After the two frame clamps 12 move in different directions, the wind turbine blades can be clamped and fixed.

[0025] The bottom end of the frame clamp 12 is fixedly connected to a tether rod 16 , and a rope can be tied to the surface of the tether rod 16 , and the wind turbine blade can be held by the rope.

[0026] Among them, both sides of the upper surface of the hanger 10 are fixedly connected with a lifting ring 11, the inner wall of the side plate 4 is fixedly connected with a sliding rod 19, and the lifting ring 11 is slidably sleeved on the surface of the sliding rod 19, which greatly improves the stability of the hanger 10 when moving.

[0027] Among them, a rod 17 is slidably inserted into the side of the frame clamp 12, one end of the rod 17 is fixedly connected to an end plate 18, and a threaded locking bolt 15 is threadedly connected to the surface of the frame clamp 12, and the end of the threaded locking bolt 15 fits with the surface of the rod 17. The rod 17 is inserted into the side of the frame clamp 12, and the rod 17 is slid into the position inside the frame clamp 12 so that the inner wall of the end plate 18 abuts against the end of the wind turbine blade. After the inner wall of the end plate 18 abuts against the end of the wind turbine blade, the threaded locking bolt 15 is tightened so that the end of the threaded locking bolt 15 fits with the surface of the rod 17, thereby increasing the friction with the surface of the rod 17, thereby fixing the position of the end plate 18.

[0028] Working principle: when the device is in use, when the wind turbine blade is hoisted, after starting the double-axis motor 5, the threaded rods 6 at both ends of the double-axis motor 5 will be driven to rotate, thereby driving the block 8 to move inside the horizontal frame 1, and at the same time, the roller 9 will slide on the upper surface of the inner edge strip 7, thereby driving the hanger 10 to move accordingly. Since the two hangers 10 move in different directions, the distance between the two hangers 10 is consistent with the model of the wind turbine blade, and then the electric telescopic rod 14 is started to drive the frame clamp 12 to move, and the two frame clamps 12 are moved. After moving in different directions, the wind turbine blades can be clamped and fixed, so that the wind turbine blades can be lifted. After the device clamps and fixes the wind turbine blades, the plug rod 17 can be inserted into the side of the frame clamp 12, and the plug rod 17 can be slid inside the frame clamp 12 so that the inner wall of the end plate 18 abuts against the end of the wind turbine blade. After the inner wall of the end plate 18 abuts against the end of the wind turbine blade, the threaded locking bolt 15 is tightened so that the end of the threaded locking bolt 15 fits against the surface of the plug rod 17, thereby increasing the friction with the surface of the plug rod 17, thereby fixing the position of the end plate 18.
