Description

Technical Field

[0001] The invention relates to the technical field of wind power generation group installation equipment, and specifically proposes a wind power generation group automatic hoisting device and a hoisting method. Background Art

[0002] Wind turbines usually refer to wind generators, which are mainly composed of a tower, a nacelle, a wind rotor and blades. The tower is installed on the foundation, and the wind rotor and blades need to be assembled on the nacelle, which needs to be assembled and fixed on the top of the tower. The height of the tower is usually at least one hundred meters, and can even reach more than two hundred meters. When installing the wind generator, it is inevitable to hoist the nacelle, the wind rotor and the blades one by one. The nacelle is the main structure for converting wind energy into electrical energy. In addition to the outer shell, the nacelle is usually equipped with core mechanical components including a transmission system, a generator, a braking system, a cooling system and a control system. Before hoisting, the mechanical components in the nacelle are usually pre-assembled in the nacelle, and the overall mass is relatively large.

[0003] Under the existing technology, corresponding professional lifting equipment is generally designed for lifting the cabin, and the existing lifting equipment is basically lifted by the cooperation of multiple lifting ropes. The lifting of the cabin is a high-altitude lifting operation. When there is wind in the air during the lifting process, the existing lifting equipment structure will inevitably cause the cabin to swing with the wind. The stronger the wind, the greater the amplitude of the swing. The swinging of the cabin during the lifting process will at least cause the following problems: (1) The swinging with the wind will pose a greater hoisting safety hazard, which may cause the cabin to collide with the tower or other structures during the lifting process, causing equipment damage and casualties, and prolonging the lifting time and operation risks.

[0004] (2) The swing of the nacelle will increase the difficulty of docking and fixing the nacelle to the tower, affecting the installation accuracy.

[0005] (3) The swinging of the cabin may cause collision and friction between the cabin and the suspension ropes, resulting in deformation and damage to the cabin structure, and also accelerate the structural damage of the suspension ropes.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] like Figure 1 , Figure 2 and Figure 7 As shown, an automatic hoisting device for a wind turbine generator set is used to hoist a nacelle 5 in a wind turbine generator set, and the device comprises a hanger 1, four hoisting ropes 2 detachably mounted on the hanger 1, four umbrella support members 3 correspondingly mounted on the four hoisting ropes 2, and two pressing mechanisms 4 for driving the umbrella support members 3. The device is used to cooperate with and dock with the lifting end of an existing crane, and is used to hoist the nacelle 5 to the top of the wind turbine generator tower.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the hanger 1 includes a main hanger beam 11 and two groups of side hanger beams 12 distributed along the length direction of the main hanger beam 11. The number of side hanger beams 12 in each group is two, and the two side hanger beams 12 in each group are symmetrically welded on both sides of the main hanger beam 11; a guide plate 111 is welded on the top of the main hanger beam 11, and a plurality of hanging holes 112 distributed along its length are opened on the guide plate 111; and two hanging hole seats 121 are welded on each side hanger beam 12. The four side hanger beams 12 are all equipped with hanging ropes 2. In addition, two hanging ropes 2 for docking with the lifting end of the crane are also equipped on the guide plate 111. The hanging ropes 2 on the guide plate 111 are not shown in the drawings. Both ends of the hanging ropes 2 are equipped with hanging rings 21 for easy disassembly. In this embodiment, the two hanging ropes 2 on the guide plate 111 are respectively hooked on Figure 3 The second and fourth hanging holes 112 from left to right in the middle, and the hanging ropes 2 located on the side hanging beams 12 are all hooked on the hanging hole seats 121 near the outer ends.

[0038] like Figure 7 Shown is a nacelle 5 of a wind turbine generator set, in which the top cover of the nacelle 5 shell is not assembled. To facilitate hoisting, two groups of avoidance holes 51 of different sizes are provided on the nacelle 5 shell, with two avoidance holes 51 in each group distributed on both sides of the axis of the nacelle 5 shell. In addition, four suspension seats are fixed inside the nacelle 5 shell, which are vertically opposite to the four avoidance holes 51. The suspension seat structure is similar to the suspension hole seat 121, and the suspension seat is not shown in the accompanying drawings.

[0039] During hoisting, the four hoisting ropes 2 are passed vertically through the four avoidance holes 51 one by one and extended into the shell of the cabin 5. The hoisting staff can enter the cabin 5 and hook the hoisting ring 21 at the lower end of each hoisting rope 2 on the corresponding hoisting seat. Figure 8 As shown in the figure, four suspension ropes 2 are correspondingly extended vertically into the avoidance holes.

[0040] like Figure 1 and Figure 4 As shown, the suspension rope 2 on each side suspension beam 12 is equipped with an umbrella support member 3; the umbrella support member 3 includes an inner support frame slidably mounted on the suspension rope 2 and four flexible clamps 34 detachably mounted on the inner support frame; the inner support frame includes a sliding sleeve 31 slidably mounted on the suspension rope 2, and hinge seat ends 311 are welded at both the upper and lower ends of the sliding sleeve 31, and four frame plates 32 are hingedly connected to the hinge seat end 311 near the bottom of the sliding sleeve 31; the four frame plates 32 are evenly distributed around the sliding sleeve 31 in the circumferential direction. A diagonal brace 33 is connected between each frame plate 32 and the sliding sleeve 31. Slide grooves 322 extending along the length direction are opened on both sides of the frame plate 32. The diagonal brace 33 includes a sliding seat 331 slidably mounted between the slide grooves 322 on both sides of the frame plate 32. Two springs 332 are welded on the sliding seat 331. A serial pin 333 is welded between the other ends of the two springs 332. The two springs 332 are hinged to the hinge seat end 311 on the sliding sleeve 31 near the top position through the serial pin 333.

[0041] like Figure 4 , Figure 6 and Figure 7 As shown, four flexible splints 34 are mounted on four frame plates 32 in a one-to-one correspondence. The flexible splints 34 are made of rubber material. A positioning groove 321 is provided on the frame plate 32 extending from the end away from the hinge in the length direction, and the positioning groove 321 is closed near the hinged end of the frame plate 32; a positioning key 341 is provided on the flexible splint 34 to be plugged into the positioning groove 321. The flexible splint 34 is positioned and installed on the frame plate 32 through the plug-in cooperation between the positioning key 341 and the positioning groove 321. The flexible splint 34 is also integrally formed with two flexible fixing sleeves 342 that are sleeved on the frame plate 32. The four flexible splints 34 are distributed circumferentially around the inner support frame, and the inclined brace 33 keeps the flexible splints 34 in an inclined state. The side clamp radius formed by the four flexible splints 34 gradually decreases from top to bottom, and the bottom position surrounded by the four flexible splints 34 can extend into the avoidance hole 51.

[0042] like Figure 1 , Figure 2 and Figure 4As shown, in order to facilitate the adjustment of the position of the umbrella support member 3 on the hanging rope 2, the hanger 1 is also equipped with two pressing mechanisms 4, the two pressing mechanisms 4 are correspondingly arranged with the two groups of side hanging beams 12, and the pressing mechanisms 4 are connected between the two umbrella support members 3 on the two side hanging beams 12 in the corresponding group; the pressing mechanism 4 includes a slider 41 horizontally slidably mounted on the guide plate 111, and two push-pull rods 43 symmetrically distributed on both sides are horizontally rotatably mounted on the slider 41, and the push-pull rods 43 are L-shaped rods, and the top ends of the sliding sleeves 31 of the two umbrella support members 3 are correspondingly welded with connecting blocks 44, and the other ends of the two push-pull rods 43 The two ends are hinged on the two connecting blocks 44 one by one; the slider 41 is also threadedly connected with a locking screw 42 for locking the slider 41 on the guide plate 111, and the locking screw 42 is vertically penetrated on the slider 41. When the locking screw 42 is pressed against the top of the guide plate 111, the slider 41 is locked. In order to ensure the reliability of the locking of the locking screw 42, the top of the guide plate 111 is evenly processed with a serrated groove along the length direction, and the lower pressing surface of the locking screw 42 is a serrated surface that can engage with the serrated groove. When locked, the locking screw 42 is engaged with the top of the guide plate 111.

[0043] After all four suspension ropes 2 are hooked on the cabin 5, the cabin 5 is slightly lifted from the ground by the crane, the hanger 1 is adjusted to maintain balance, and the four suspension ropes 2 are all in a vertically taut state, and then the two groups of umbrella support members 3 are correspondingly pressed at the two groups of avoidance holes 51 through the two pressing mechanisms 4 in turn. Specifically, the locking screws 42 are loosened, and the two push-pull rods 43 are held to drive the slider 41 to slide, thereby synchronously pushing the two umbrella support members 3 to slide down along the suspension ropes 2 through the push-pull rods 43, so that the umbrella support members 3 are inserted into the corresponding avoidance holes 51 as a whole, and by continuing to press down and adjust, under the common support of the inclined member 33 and the skeleton plate 32 on the flexible splint 34, the four flexible splints 34 are independently and adaptively clamped and contacted at the edge of the avoidance hole 51, and pressed against the outer wall of the cabin 5 shell, and then the locking screws 42 are tightened to lock the slider 41 and fix the position of the umbrella support member 3. By coordinating, positioning and clamping multiple umbrella support members 3 at the avoidance holes 51, the umbrella support members 3 indirectly constitute the support points between the suspension rope 2 and the cabin 5, thereby improving the integrity between the cabin 5 and the lifting equipment and limiting the freedom of the cabin 5 to swing relative to the lifting equipment. In addition, the independent adaptive clamping contact of the multiple flexible splints 34 in the umbrella support member 3 ensures multi-point support, and the umbrella support member 3 has its own damping function, which can absorb the impact force generated during the swinging of the cabin 5 and weaken the swinging amplitude, and constitutes an isolation protection between the cabin 5 and the suspension rope 2 to avoid direct collision and friction between the cabin 5 and the suspension rope 2.

[0044] While the cabin 5 is being assisted in being fixed by the umbrella support member 3, the cabin 5 is hoisted and docked to the top of the tower by a crane. After the cabin 5 is locked and fixed to the top of the tower by professionals, the lifting rope 2 is removed, and the lifting equipment is driven vertically upward by the crane. The clamping force between the umbrella support member 3 and the cabin 5 is naturally released, and the lifting rope 2 moves outward from the avoidance hole 51, thereby completing the separation between the lifting equipment and the cabin 5 and completing the lifting of the cabin 5.

[0045] In addition, if Figure 1-Figure 9 As shown, the present invention also provides a method for automatically hoisting a wind power generation group, comprising the following steps: S1, docking the hoisting equipment at the lifting end of the crane.

[0046] S2. Place the cabin 5 stably on the ground, pass the sling rope 2 vertically through the corresponding avoidance hole 51 on the outer shell of the cabin 5, and extend it into the cabin 5.

[0047] S3, hook the lifting end of the lifting rope 2 to the lifting point position set in the cabin 5.

[0048] S4. Lift the cabin 5 so that the lifting rope 2 is taut.

[0049] S5 , inserting the umbrella support member 3 into the avoidance hole 51 and pressing it tightly through the pressing mechanism 4 .

[0050] S6. Hoist the nacelle 5 to the top of the tower. After the nacelle 5 is fixedly installed, remove the hoisting equipment from the nacelle 5.
