Description

Technical Field

[0001] The invention relates to the technical field of web bonding and hoisting, and in particular to an integrated hoisting device for bonding a small web of a wind turbine blade SS surface. Background Art

[0002] Wind power generation refers to the process of using wind energy to drive wind turbines to rotate, converting the kinetic energy of wind into mechanical energy, and then converting mechanical energy into electrical energy. In simple terms, it is to use wind to generate electricity. Specifically, wind blows through the blades of wind turbines, generating lift and drag, driving the blades to rotate. The rotation of the blades drives the rotor inside the generator to rotate, converting the kinetic energy of wind into mechanical energy. The rotation of the rotor cuts the magnetic lines of force, generates induced current, and converts mechanical energy into electrical energy. The existence of blades is crucial in wind power generation. Wind turbine blades are key components for converting wind energy into mechanical energy. Their design, manufacture and performance are crucial to the efficiency and reliability of wind power generation. The web in the wind turbine blade is a key structural component inside the blade. It mainly plays the role of bearing shear force, increasing blade stiffness, transferring loads and dividing internal space.

[0003] The webs in wind turbine blades are installed by lifting them to the bonding position in the blades with large lifting equipment. In order to avoid interference between the bottom of the web and the inner surface of the blade during lifting, the existing lifting equipment has no supporting structure at the bottom of the web, and only relies on a clamping and positioning mechanism to clamp and lift the two sides of the web. During the lifting process, if there is looseness and slippage between the web surface and the clamping and positioning mechanism, it will directly cause the web to fall and be damaged. In addition, if the lifting equipment as a whole accidentally falls during the lifting process, it will cause certain damage to the overall equipment and the web. Summary of the invention

If there is looseness and slippage between the belly plate surface and the clamping and positioning mechanism during the lifting process, it will directly cause the belly plate to fall and be damaged.

[0032] like Figure 1-8As shown, the security component 6 is arranged on the outside of the lifting truss 1, and the security component 6 includes a buffer for preventing the frame from being damaged when the lifting truss 1 falls suddenly. The buffer includes a plurality of hollow limit frames 61 fixed on the top of the lifting truss 1 and a plurality of hollow tubes 62 fixed on the outside of the lifting truss 1. The plurality of hollow limit frames 61 and the plurality of hollow tubes 62 are arranged in two rows, and each hollow tube 62 corresponds to a hollow limit frame 61, respectively. A plurality of air holes 63 are opened on the outside of the plurality of hollow tubes 62, and the air holes 63 are close to the lower end of the hollow tube 62 for the inlet and outlet of air flow. A piston 64 is arranged inside the plurality of hollow tubes 62, and a rubber layer is arranged on the periphery of the piston 64. Connecting rods 65 are fixed on the top of the plurality of pistons 64. Multi-layer support frames 66 are fixed on the outside of the plurality of hollow limit frames 61, and a plurality of multi-layer support frames 66 are arranged between the inner sides. A lifting connection piece is provided, and temporary suspension pieces are provided on the outside of the multiple hollow cylinders 62. A rubber bottom plate 67 is provided under the temporary suspension pieces. The lifting connection piece includes multiple driving frames 68 and multiple lifting rings 69 that slide between the inner sides of the multiple multi-layer support frames 66. The multiple driving frames 68 are arranged vertically. Among the multiple driving frames 68, there is a part that is particularly long in different layers of the multi-layer support frames 66. The two ends of this longer part are respectively fixedly connected to one end of two connecting rods 65 located below it. The multiple lifting rings 69 are fixed above the driving frame 68 at the bottom. The driving frame 68 at the bottom is connected to one end of the connecting rod 65 in the longest hollow cylinder 62. The longest hollow cylinder 62 is set at the position with the largest web size. And so on, the driving frame 68 is fixedly connected to one end of the connecting rod 65 in the remaining hollow cylinders 62.

[0033] like Figure 1-8 As shown, the temporary suspension member includes a fixing ring 610 fixed to the outside of the hollow cylinder 62 and a plurality of connecting plates 611 fixed to the outside of the hollow cylinder 62. The plurality of connecting plates 611 are all located at one end close to the hollow cylinder 62, and a pull rod 612 is penetrated inside the connecting plates 611. A round piece with a diameter slightly larger than the rod body diameter of the pull rod 612 is provided at one end of the pull rod 612. A connecting piece 613 is fixed between one end of the plurality of pull rods 612. The lower part of the connecting piece 613 is connected to the hollow cylinder 62 by rotating the connecting head. The rubber bottom plate 67 is connected, and the rubber bottom plate 67 can be flexibly rotated 360 degrees to change its angle with the connecting piece 613. A plurality of through holes 614 are opened inside the fixing ring 610, and the through holes 614 correspond to a section of the pull-out rod 612, and the size of the through holes 614 is adapted to the size of the disc at one end of the pull-out rod 612, so as to facilitate the passage of the pull-out rod 612. A plurality of first springs 615 are fixed below the fixing ring 610, and one end of each of the plurality of first springs 615 is fixed above the rubber bottom plate 67.

[0034] like Figure 1-8As shown, the security component 6 also includes two belly plate anti-falling parts, which are respectively arranged on the outside of the two groups of hollow cylinders 62 at the edge, and the belly plate anti-falling parts are used to reinforce the stability of the belly plate during lifting. The belly plate anti-falling parts include mounting shells 616 respectively installed on the outside of the two hollow cylinders 62, and the two mounting shells 616 are respectively located below the two rows of hollow limit frames 61. The two mounting shells 616 are arranged opposite to each other, and the insides of the two mounting shells 616 are both slid with inclined sliding columns 617, and one end of the two inclined sliding columns 617 extends to the inside of the two hollow cylinders 62 respectively, and the inclined sliding columns 617 are located above the piston 64. The other end of the inclined sliding column 617 extends to the outside of the two mounting shells 616 respectively. The inclined sliding column 617 is slidably connected at the penetration point. One end of the two inclined sliding columns 617 is fixed with an L-shaped connecting strip 618. A supporting bottom plate 619 is slidably provided under the two L-shaped connecting strips 618. The supporting bottom plate 619 is positioned by means of screws and the L-shaped connecting strip 618. The two supporting bottom plates 619 are fixedly connected to the first web surface positioning member 41 and the second web surface positioning member 42 respectively. Two second springs 620 are fixed inside the two mounting shells 616, and one end of the two second springs 620 is fixed on the inclined sliding column 617.

[0035] When in use, the web is placed above a plurality of web ground storage racks 3, and the two surfaces of the web are clamped and fixed by using the first web surface positioning member 41 and the second web surface positioning member 42. When the web is clamped by the first web surface positioning member 41 and the second web surface positioning member 42, the bottom support plates 619 located on the two surfaces of the web will be close to both sides of the web, and the lifting truss 1 is lifted upward by using the hook and the lifting ring 69. When lifting, the driving frame 68 at the bottom is first pulled upward by the lifting ring 69, and the driving frame 68 then pulls the two connecting rods 65 connected thereto upward, and the two connecting rods 65 then pull the piston 64 connected thereto upward, until the driving frame 68 moves up to the nearest driving frame above it. The movable frame 68 drives the driving frame 68 to move upward, and the driving frame 68 will drive the connecting rod 65 and the piston 64 connected thereto to move upward, and so on, until the top driving frame 68 is pulled upward, at which time all the connecting rods 65 and the piston 64 inside the hollow tube 62 are pulled upward, and the upward movement of the piston 64 draws external air into the hollow tube 62 through the air hole 63, until the piston 64 pushes the inclined sliding column 617 above it to the outside of the hollow tube 62, and the inclined sliding column 617 pushes the supporting plate 619 to the bottom of the web through the L-shaped connecting strip 618 to support the bottom of the web, so as to prevent the web from accidentally falling and being damaged due to improper clamping of the adjustable web limit assembly 4 during lifting.

[0036] When the hoisting truss 1 falls accidentally, the rubber bottom plate 67 will first contact the ground or the inner surface of the blade, and when the hoisting truss 1 continues to fall, the driving frame 68 relies on its own gravity to push the connecting rod 65 and the piston 64 downward inside the hollow tube 62, and the air in the hollow tube 62 is pushed out from the air hole 63. When the piston 64 moves downward quickly due to the impact force of falling to the ground, the air in the hollow tube 62 is compressed, and the compressed air generates a reaction force, which is also transmitted to the hollow tube 62, reducing the impact on the hollow tube 62, reducing the contact impact strength between the hollow tube 62 and the hoisting truss 1 and the ground, and reducing the damage rate of the hoisting truss 1 and the web after buffering the impact of falling to the ground.

[0037] When the web is hoisted to the bonding position, the hoisting truss 1 descends to drop the web inside the wind turbine blade. Before the web contacts the inner surface of the blade, the rubber bottom plate 67 contacts the inner surface of the blade first. When the hoisting truss 1 continues to move downward, the hollow cylinder 62 falls down, and the first spring 615 is compressed under the push of the fixing ring 610, and the pulling rod 612 gradually passes through the through hole 614 until the hollow cylinder 62 cannot move downward. At the same time, under the push of the driving frame 68, the piston 64 moves downward to press the hollow cylinder 62. The air is squeezed out, and the inclined sliding column 617 will slide into the hollow cylinder 62 under the reset of the second spring 620, and pull the L-shaped connecting strip 618 and the supporting base plate 619 to move the supporting base plate 619 away from under the web before the web contacts the inner surface of the blade. Then, the screw fixing the supporting base plate 619 is loosened, and the first web surface positioning member 41 and the second web surface positioning member 42 are moved away from the web. After the supporting base plate 619 is driven away from the web, the lifting truss 1 can be lifted up and moved aside.

[0038] The above description is only a preferred embodiment of the present invention, which is only illustrative and not restrictive of the present invention. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims of the present invention, but all of them will fall within the scope of protection of the present invention.
