Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade support technology, and in particular to a wind turbine blade lifting device. Background Technology

[0002] Wind turbine blades are key components used in wind turbine generator sets. They capture wind energy and convert it into mechanical energy, which then drives the generator to produce electricity. During the production process of wind turbine blades, they need to be placed inside the factory and then transferred to vehicles during transportation. In order to effectively avoid damage to the wind turbine blades, a support and lifting structure is needed to support them. Most existing wind turbine blade lifting devices are simple clamping structures. Although they have a good fixing and lifting effect, they have low flexibility and poor applicability. They cannot adjust the clamping state according to different blade sizes. Therefore, this application is made. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a wind turbine blade lifting device, which has the characteristics of wide applicability and simple and convenient operation.

[0004] The technical solution adopted by this utility model is as follows: It includes a blade end fixing seat and a blade tail fixing seat. A cable reel is provided on the side wall of the blade end fixing seat. The blade tail fixing seat is connected to the cable reel via a connecting cable. Lateral telescopic rods are symmetrically arranged on both sides of the blade end fixing seat and the blade tail fixing seat. A longitudinal telescopic rod is connected to the telescopic end of the lateral telescopic rod via an L-shaped rod. A roller is fixedly installed at the bottom of the longitudinal telescopic rod. Through the arrangement of the lateral and longitudinal telescopic rods, the height of the blade end fixing seat and the space below it can be adjusted to facilitate lifting and placing the wind turbine blade placed on the ground. Inside the transport vehicle, both the blade end fixing seat and the blade tail fixing seat have mounting slots on their tops. A bidirectional synchronous drive is installed in the mounting slot. Two annular adaptive clamping components are connected to the bidirectional synchronous drive in the blade end fixing seat, and two binding components are connected to the bidirectional synchronous drive in the blade tail fixing seat. The two bidirectional synchronous drive controls the synchronous movement of the annular adaptive clamping components and the binding components, respectively. The two annular adaptive clamping components are used to fix the blade end in an annular shape, and the two binding components are used to bind and fix the blade tail. Both are adaptive structures and can be used to fix wind turbine blades of different sizes.

[0005] Preferably, the bidirectional synchronous drive consists of a first motor and a bidirectional lead screw fixed in the mounting groove. One end of the bidirectional lead screw is fixed on the output shaft of the first motor, and the other end is rotatably connected to the inner wall of the mounting groove. The first motor controls the rotation of the bidirectional lead screw, and the two opposite threads on the bidirectional lead screw control the movement of the annular adaptive clamping component or binding assembly.

[0006] Preferably, a limit post is provided at the center of the bidirectional lead screw to prevent the annular adaptive clamping component or the binding assembly from getting too close.

[0007] Preferably, the annular adaptive clamping member includes a sliding seat slidably disposed in the mounting groove and an arc-shaped clamping plate fixedly disposed on the top of the sliding seat by a connecting piece. The sliding seat is threadedly connected to a bidirectional lead screw, so that the bidirectional lead screw can drive the sliding seat to move laterally in the mounting groove when rotating.

[0008] Preferably, the arc-shaped clamping plate is provided with a rotating extrusion column with an elliptical cross-section. The outer wall of the rotating extrusion column is provided with an anti-slip pad. The elliptical rotating extrusion column can adjust the position of its major and minor axes when rotating, so as to adaptively clamp the ends of blades of different diameters.

[0009] Preferably, a second motor is fixedly installed on the side wall of the arc-shaped clamping plate. The output shaft of the second motor is fixedly connected to the side wall axis of the rotating extrusion column. The rotating extrusion column is rotated and adjusted by the second motor. In actual application, both the first motor and the second motor are servo motors with a self-locking structure to ensure the stability of the structure.

[0010] Preferably, the binding assembly includes a movable seat slidably disposed in the mounting groove, an outer expansion plate fixedly disposed on the top of the movable seat, and a storage tube fixed at one end of the outer expansion plate. The movable seat is threadedly connected to a bidirectional lead screw. The rotation of the bidirectional lead screw controls the movable seat to slide in the mounting groove, thereby adjusting the position of the storage tube above. This makes it easy to retract the storage tube when not in use and to move it outward when in use, facilitating the fixing of blades of different sizes.

[0011] Preferably, the binding assembly further includes a winding cylinder, in which a winding rod is rotatably disposed. Several binding straps are wound inside the storage cylinder via a rotating roller. One end of each binding strap is inserted into the winding cylinder and fixed to the winding rod. In actual use, a drive hole is provided at one end of the winding rod. By inserting an external drive component to control the rotation of the winding rod, the binding straps can be wound up, thereby binding and fixing the blade located in the middle of the binding straps. After binding and fixing, the winding rod is fixed to prevent it from rotating.

[0012] The beneficial effects of this utility model are as follows: This utility model controls the synchronous movement of the annular adaptive clamping component and the binding component by two bidirectional synchronous driving components respectively. The two annular adaptive clamping components are used to fix the end of the blade in an annular shape, and the two binding components are used to bind and fix the tail of the blade. Both are adaptive structures, which can be applied to the fixing of wind turbine blades of different sizes. The operation is simple and convenient, and it has high applicability and high practical value.

[0013] This invention, through the setting of horizontal and vertical telescopic rods, can adjust the height of the blade end fixing seat and the blade tail fixing seat as well as the space below, enabling the wind turbine blades placed on the ground to be quickly and easily lifted and placed into the transport vehicle.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-5As shown, this embodiment provides a wind turbine blade lifting device, including a blade end fixing seat 1 and a blade tail fixing seat 2. A cable reel 10 is provided on the side wall of the blade end fixing seat 1. The blade tail fixing seat 2 is connected to the cable reel 10 via a connecting cable 11. The cable reel 10 controls the winding and unwinding of the connecting cable 11, allowing for flexible adjustment of the distance between the blade end fixing seat 1 and the blade tail fixing seat 2 according to the blade length and the length of the transport vehicle to meet different usage requirements. Lateral telescopic rods 7 are symmetrically arranged on both sides of the blade end fixing seat 1 and the blade tail fixing seat 2. A longitudinal telescopic rod 8 is connected to the telescopic end of the lateral telescopic rod 7 via an L-shaped rod. A roller 9 is fixedly installed at the bottom of the longitudinal telescopic rod 8. By setting the horizontal telescopic rod 7 and the vertical telescopic rod 8, the height of the blade end fixing seat 1 and the blade tail fixing seat 2 and the space below can be adjusted. This structural design makes it easy to lift the wind turbine blades placed on the ground and put them into the transport vehicle. The specific operation is as follows: control the horizontal telescopic rod 7 and the vertical telescopic rod 8 to extend at the same time, lift the blade end fixing seat 1 and the blade tail fixing seat 2 to a high position, and at the same time make a large space below. At this time, drive the transport vehicle to the lower position, then control the horizontal telescopic rod 7 and the vertical telescopic rod 8 to retract, so that the blade end fixing seat 1 and the blade tail fixing seat 2 are lowered onto the transport vehicle. At the same time, the telescopic rods are retracted to prevent scratches. Finally, the blade end fixing seat 1 and the blade tail fixing seat 2 are fixed on the vehicle.

[0022] Both the blade end fixing seat 1 and the blade tail fixing seat 2 have mounting grooves 3 on their tops. A bidirectional synchronous drive 4 is installed in the mounting groove 3. Two annular adaptive clamping parts 5 are connected to the bidirectional synchronous drive 4 in the blade end fixing seat 1, and two binding components 6 are connected to the bidirectional synchronous drive 4 in the blade tail fixing seat 2. The two bidirectional synchronous drive 4 control the synchronous movement of the annular adaptive clamping parts 5 and the binding components 6 respectively. The two annular adaptive clamping parts 5 are used to fix the blade end in an annular shape, and the two binding components 6 are used to bind and fix the blade tail. Both are adaptive structures, which can be used to fix wind turbine blades of different sizes. They are simple and convenient to operate and have high applicability and practical value.

[0023] The bidirectional synchronous drive component 4 consists of a first motor 401 fixed in the mounting groove 3 and a bidirectional lead screw 402. One end of the bidirectional lead screw 402 is fixed on the output shaft of the first motor 401, and the other end is rotatably connected to the inner wall of the mounting groove 3. The first motor 401 controls the rotation of the bidirectional lead screw 402. The two opposite threads on the bidirectional lead screw 402 control the movement of the annular adaptive clamping component 5 or the binding assembly 6. A limit post 403 is provided at the center of the bidirectional lead screw 402 to prevent the annular adaptive clamping component 5 or the binding assembly 6 from getting too close.

[0024] The annular adaptive clamping component 5 includes a sliding seat 501 slidably disposed in the mounting groove 3 and an arc-shaped clamping plate 503 fixedly disposed on the top of the sliding seat 501 via a connecting piece 502. The sliding seat 501 is threadedly connected to a bidirectional lead screw 402, so that the bidirectional lead screw 402 can drive the sliding seat 501 to move laterally in the mounting groove 3 when rotating. An elliptical rotating extrusion column 504 is disposed in the arc-shaped clamping plate 503. An anti-slip pad 505 is disposed on the outer wall of the rotating extrusion column 504. The elliptical rotating extrusion column 504 can adjust the position of its major and minor axes when rotating, so as to adaptively clamp the ends of blades of different diameters. A second motor 506 is fixedly installed on the side wall of the arc-shaped clamping plate 503. The output shaft of the second motor 506 is fixedly connected to the axis of the side wall of the rotating extrusion column 504. The rotating extrusion column 504 is rotated and adjusted by the second motor 506. In actual application, both the first motor 401 and the second motor 506 are servo motors with a self-locking structure to ensure the stability of the structure.

[0025] The binding assembly 6 includes a movable base 601 slidably disposed within the mounting groove 3, an outer expansion plate 602 fixedly disposed on the top of the movable base 601, and a storage cylinder 603 fixed at one end of the outer expansion plate 602. The movable base 601 is threadedly connected to a bidirectional lead screw 402. The rotation of the bidirectional lead screw 402 controls the sliding of the movable base 601 within the mounting groove 3, thereby adjusting the position of the storage cylinder 603 above. This allows the storage cylinder 603 to be retracted when not in use and moved outwards when in use, facilitating the fixing of blades of different sizes. The binding assembly 6 also... The device includes a winding drum 605, inside which a winding rod 606 is rotatably mounted. Several binding straps 604 are wound inside a storage drum 603 via a rotating roller. One end of each binding strap 604 is inserted into the winding drum 605 and fixed to the winding rod 606. In actual use, a drive hole is provided at one end of the winding rod 606. By inserting an external drive component to control the rotation of the winding rod 606, the binding straps 604 can be wound up, thereby binding and fixing the blades located in the middle of the binding straps 604. After binding and fixing, the winding rod 606 is fixed to prevent it from rotating.
