Description

Technical Field

[0001] The invention belongs to the technical field of wind turbine generators, and in particular relates to a blade and hub combination auxiliary device. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. A wind turbine generally consists of a wind wheel, a generator (including a device), a direction regulator (tail wing), a tower, a speed limiting safety mechanism, and an energy storage device. For a wind turbine, the rotor blades are the most important key equipment. By capturing the wind, the wind force can be transmitted to the rotor axis, and the blades are assembled on the hub when in use.

[0003] The assembly of the blades and hub of a wind turbine generally requires the use of a crane. The blades are suspended to one side of the hub interface by means of the crane and straps, so that the end of the blades gradually approaches the hub interface, and finally the connecting rod of the blades is combined with the annular plug of the hub. In this process, due to the external environment, such as wind interference, manpower is generally required to assist the docking of the blades and the hub. In order to maintain stability, the blades are wrapped with ropes on both sides of the blades, and the two sides are pulled by manpower to keep the front end of the blades as stable as possible in the left and right directions. Therefore, more manpower is consumed. Summary of the invention

When the wind blade 2 is assembled, the wind blade 2 is lifted as a whole by a crane combined with a binding strap, so that the front end plug of the wind blade 2 is close to the interface of the wind hub 1 and finally combined. When the mounting base plate 4 is in use, it needs to be placed in front of the interface of the wind wheel hub 1. The connection between the two sets of mounting side plates 5 and the mounting base plate 4 is provided with a side plate rotation shaft 7, and the mounting side plates 5 can be rotated by the side plate rotation shaft 7. In the initial state, the two sets of mounting side plates 5 are attached to the side surfaces of the mounting base plate 4. When they need to be used, the two sets of mounting side plates 5 are rotated to the unfolded state. The unfolded two sets clamp the wind wheel hub 1 inside, and the length of the mounting side plates 5 is greater than the length of the mounting base plate 4, so that the front end of the mounting base plate 4 is as close to the bottom of the wind wheel hub 1 as possible, and a side plate extension plate is fixed at the end of the mounting side plate 5. 8. At the same time, a bottom plate extension plate 6 distributed up and down is fixed at the end of the installation bottom plate 4, so that the side plate extension plate 8 extends between the bottom plate extension plates 6, and an extension plate positioning hole 9 is opened on the surface of the bottom plate extension plate 6, and an opening adapted to the extension plate positioning hole 9 is opened on the surface of the side plate extension plate 8. When the side plate extension plate 8 is rotated by an angle, the insertion rod can be inserted into the extension plate positioning hole 9 and the side plate extension plate 8 to fix the side plate extension plate 8, and the extension plate positioning holes 9 are arranged in multiple groups in an arc shape. The side plate extension plate 8 is rotated to the bottom of the corresponding extension plate positioning hole 9, so as to change the rotation angle of the installation side plate 5.

[0041] The upper binding rope 27 is attached to the end surface of the blade outer ring plate 3 close to the end of the wind blade 2, and the lower binding rope 28 is placed under the wind blade 2. The end of the lower binding rope 28 is connected to the upper binding rope 27, which can be wrapped around the outside of the wind blade 2 and attached to the side of the blade outer ring plate 3. The two ends of the lower binding rope 28 are connected to the binding rope connecting rod 29 of the cylindrical structure through the rotating shaft, and a binding rope connecting block 31 is fixed at the end of the upper binding rope 27, and a binding rope insertion hole 32 is opened on the surface of the binding rope connecting block 31 to allow the binding rope connecting rod 29 to slide through. The inner movement of the binding rope insertion hole 32 can adjust the clamping strength of the lower binding rope 28 and the upper binding rope 27 on the outer wall of the wind blade 2, and a long strip groove is provided on the surface of the connecting rod side plate 30, and a plurality of connecting rod side plates 30 are fixedly arranged at intervals in the groove, and a connecting block side hole 33 is provided on the side of the binding rope connecting block 31, and a sliding protrusion 34 is slidably connected in the hole of the connecting block side hole 33, and one end of the sliding protrusion 34 extends into the synchronization plug-in 42, and the other end passes through the connecting block side hole 33 and extends to the outside of the binding rope connecting block 31, and the bending portion of the sliding protrusion 34 The second spring part 35 is connected, and the other end of the second spring part 35 is connected to the outside of the rope connection block 31, and a stopper is fixed to the front end of the sliding protrusion 34 extending into the rope insertion hole 32, and a side hole allowing the stopper to hide is opened on the side of the rope insertion hole 32. In the initial state, the side hole 33 of the connecting block extends into the hole of the rope insertion hole 32. When the rope connecting rod 29 extends into the rope insertion hole 32, the connecting rod side plate 30 will lift the sliding protrusion 34 to compress the second spring part 35, and the upper rope 27 and the lower rope 28 will tightly bind the outside of the wind blade 2. The elastic action of the second spring part 35 allows the block at the front end of the sliding protrusion 34 to extend into the gap between the two adjacent groups of connecting rod side plates 30, and the block is used to limit the connecting rod side plates 30, so that the connecting rod side plates 30 cannot move back. Therefore, the upper binding rope 27 and the lower binding rope 28 can complete the surrounding locking of the wind blade 2. When it needs to be removed, it is only necessary to pull the sliding protrusion 34 outward to pull the block in front of the sliding protrusion 34 away from the inner side of the connecting rod side plate 30, and the binding rope connecting rod 29 can be pulled out of the hole in the binding rope insertion hole 32.

[0042] A locking ring 36 of an annular structure is fixed to the side wall of the rope connection block 31, and the inner side of the locking ring 36 is used for buckling one end of the pull rope. A groove is set at the top of the mounting base plate 4, and a screw rod 23 is installed in the groove. One end of the screw rod 23 is connected to the driving motor 24, and a moving kit 39 is also arranged in the groove, which is engaged and sleeved on the outside of the screw rod 23. The moving kit 39 is driven by the driving motor 24 to move radially along the screw rod 23. A moving plate body 25 is fixed on the top of the moving kit 39, and a plurality of groups of connecting buckle rods 26 distributed at intervals are fixed on the top of the moving plate body 25. Each group of connecting buckle rods 26 is L-shaped, and the connecting buckle rods 26 are used for buckling the other end of the pull rope. A guide plate 12 and a steering pulley 14 are set on the top of the mounting side plate 5, wherein the steering pulley 14 can rotate freely on the inner side of the guide plate 12, wherein one end of the pull rope is combined with the locking ring 36, and the other end of the pull rope is passed through the gap between the steering pulley 14 and the guide plate 12 and then buckled with the connecting buckle rod 26 to form a fixed pulley structure. In this way, when the movable plate body 25 moves, the pull rope transmits the force to the locking ring 36 through the steering pulley 14, so that the locking ring 36 drives the binding rope connecting block 31 and then makes the wind blade 2 clamped by the upper binding rope 27 and the lower binding rope 28 move toward the interface of the wind wheel hub 1. At the same time, the pull ropes on both sides are in a taut state, so they can resist the interference of external wind force to a certain extent, improve the left and right stability of the wind blade 2 in the process of approaching the wind wheel hub 1, thereby improving the effect of connecting the wind blade 2 with the wind wheel hub 1 and reducing manpower.

The outer wall of the mounting column plate 10 is fixed with a column plate positioning convex rod 19 that moves along the convex rod limiting groove 17 and the side slot. When the mounting column plate 10 is longitudinally combined with the column plate jack 16, the column plate positioning convex rod 19 moves downward along the convex rod limiting groove 17. When the column plate positioning convex rod 19 reaches the side of the convex rod limiting groove 17, the convex rod 19 is fixed to the outer wall of the mounting column plate 10. When the column plate 10 is installed in the slot, the column plate 10 can be rotated so that the column plate positioning convex rod 19 enters the side slot. When the column plate positioning convex rod 19 falls into the position of the measuring slot, the positioning push rod 20 moves in the groove of the limiting connecting groove 18 through the elastic action of the spring part 1 21, so that the cover plate 22 moves toward the hole of the convex rod limiting groove 17, so that the cover plate 22 blocks the hole of the convex rod limiting groove 17, so that the column plate positioning convex rod 19 cannot move from the convex rod limiting groove 17. By disengaging upward, the column plate 10 and the column plate socket 16 can be installed and combined. When the column plate 10 needs to be disengaged from the groove of the column plate socket 16, it is only necessary to pull the positioning push rod 20 in the groove of the limiting connecting groove 18 toward the side away from the convex rod limiting groove 17, so that the cover plate 22 can be separated from the hole of the convex rod limiting groove 17, and the column plate positioning convex rod 19 can be moved longitudinally along the groove of the convex rod limiting groove 17 to disengage the column plate 10 from the hole of the column plate socket 16.
