Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine gearbox processing equipment, and in particular to an assembly platform for wind turbine gearboxes. Background Technology

[0002] The wind turbine gearbox is used to transmit the power generated by the wind turbine under the action of wind to the generator and enable it to achieve the corresponding speed. It is an important component in the wind turbine generator set. When assembling the wind turbine gearbox, the wind turbine gearbox needs to be fixed on the assembly platform, and then the internal parts are hoisted into the wind turbine gearbox and assembled manually by workers.

[0003] However, wind turbine gearboxes contain gears with gear shafts, which are incompatible with commonly used gear lifting tools. During assembly, the lifting tools need to be changed frequently depending on the type of gear.

[0004] Meanwhile, after the lifting device is moved above the wind turbine gearbox, it will sway due to inertia. The staff needs to wait for the sway to decrease before they can continue to operate the crane to lower the lifting device, resulting in low assembly efficiency.

[0005] To address these issues, an assembly platform for wind turbine gearboxes is proposed. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the existing wind turbine gearbox processing equipment that require frequent changes of lifting tools and waiting for the shaking to decrease before continuing operation, and proposes a wind turbine gearbox assembly platform.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An assembly platform for a wind turbine gearbox includes a base with a fixed groove at its center. Support columns are fixedly installed at both ends of the base. A limiting rod and a lead screw are provided between the support columns. The limiting rod is located below the lead screw and is fixedly connected to the support column. The lead screw is rotatably connected to the support column. A moving motor is connected to the lead screw through the support column. A moving disk is connected to the outer wall of the limiting rod and the lead screw. A lifting assembly is provided at the bottom of the moving disk. A sway suppression assembly is provided inside the moving disk. The sway suppression assembly includes a synchronous drive mechanism and a clamping mechanism, which are equidistantly arranged around the center of the moving disk.

[0009] The two sides of the movable disk are slidably connected to the limiting rod, and the two sides of the movable disk are threadedly connected to the lead screw.

[0010] Preferably, the shape of the fixing groove matches the wind turbine gearbox, and a positioning column is fixedly connected inside the fixing groove.

[0011] Preferably, the hoisting assembly includes a crane, a hoisting platform is fixedly connected to the bottom of the crane, a through hole is opened in the center of the hoisting platform, and four electromagnets are fixedly connected to the bottom of the hoisting platform.

[0012] Preferably, the four electromagnets are arranged around and away from the through hole.

[0013] Preferably, the synchronous drive mechanism includes a ring-shaped rotating seat, in which a synchronous gear ring and a lifting gear ring are rotatably connected from top to bottom. The synchronous gear ring is engaged with a clamping motor, and the lifting gear ring is engaged with a lifting motor.

[0014] Preferably, the clamping mechanism includes a clamping spline hub and a lifting spline hub. The outer walls of both the clamping spline hub and the lifting spline hub are provided with tooth blocks. The clamping spline hub is engaged with a synchronous toothed ring, and the lifting spline hub is engaged with a lifting toothed ring.

[0015] Preferably, the clamping spline hub and the lifting spline hub are keyed together with ball splines, and the bottom of the ball splines is fixedly connected with a suppressing clamp.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model, by setting up a hoisting assembly, uses an electromagnet to attract the required accessories inside the wind turbine gearbox. When hoisting a gear with a gear shaft, the gear shaft can pass through the through hole opened in the center of the hoisting plate, so that there is no need to change the hoisting tool when hoisting this kind of gear, thus realizing the function of hoisting different parts.

[0018] 2. This utility model, by setting up a sway suppression component, uses a lifting motor to drive a lifting gear ring to rotate the lifting spline hub counterclockwise. The lifting spline hub then drives the ball spline to descend vertically to a suitable position. Next, a clamping motor drives a synchronous gear ring to rotate the clamping spline hub synchronously counterclockwise. The clamping spline hub then drives the ball spline to rotate synchronously, which in turn drives the suppression clamping plate to rotate synchronously. The suppression clamping plate clamps the hanging plate from all sides, thereby suppressing the swaying of the hanging plate caused by inertia before assembly. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1-6 An assembly platform for a wind turbine gearbox includes a base 1, a fixing groove 2 at the center of the base 1, and support columns 3 fixedly installed at both ends of the base 1. A limiting rod 4 and a lead screw 5 are provided between the support columns 3. The limiting rod 4 is located below the lead screw 5 and is fixedly connected to the support column 3. The lead screw 5 is rotatably connected to the support column 3. The lead screw 5 passes through the support column 3 and is connected to a moving motor 6. A moving disk 7 is connected to the outer wall of the limiting rod 4 and the lead screw 5. A hoisting assembly is provided at the bottom of the moving disk 7. A sway suppression assembly is provided inside the moving disk 7. The sway suppression assembly includes a synchronous drive mechanism and a clamping mechanism. The clamping mechanism is equidistantly arranged around the center of the moving disk 7.

[0028] The two sides of the movable disk 7 are slidably connected to the limiting rod 4, and the two sides of the movable disk 7 are threadedly connected to the lead screw 5.

[0029] Furthermore, the shape of the fixing groove 2 matches the wind turbine gearbox, and a positioning column 8 is fixedly connected inside the fixing groove 2 to limit the movement of the wind turbine gearbox.

[0030] Furthermore, the hoisting assembly includes a crane 9, with a hoisting plate 10 fixedly connected to the bottom of the crane 9. The hoisting plate 10 has a through hole in its center, and four electromagnets 11 for adsorbing wind turbine gearbox accessories are fixedly connected to the bottom of the hoisting plate 10. The four electromagnets 11 are arranged around and away from the through hole.

[0031] It should be noted that crane 9 is existing technology and will not be described further below.

[0032] A further advantage of the above is that, during hoisting, the electromagnet 11 attracts the required accessories inside the wind turbine gearbox. When hoisting a gear with a gear shaft, the gear shaft can pass through the through hole in the center of the hoisting plate 10, so that there is no need to change the hoisting tool when hoisting this kind of gear, thus realizing the function of hoisting different parts.

[0033] Furthermore, the synchronous drive mechanism includes a ring-shaped rotating seat 12, in which a synchronous gear ring 13 and a lifting gear ring 14 are rotatably connected from top to bottom. The synchronous gear ring 13 is engaged with a clamping motor 15, and the lifting gear ring 14 is engaged with a lifting motor 16.

[0034] Furthermore, the clamping mechanism includes a clamping spline hub 17 and a lifting spline hub 18. The outer walls of both the clamping spline hub 17 and the lifting spline hub 18 are provided with tooth blocks. The clamping spline hub 17 is meshed with the synchronous toothed ring 13, and the lifting spline hub 18 is meshed with the lifting toothed ring 14. The clamping spline hub 17 and the lifting spline hub 18 are keyed with ball splines 19, and the bottom of the ball splines 19 is fixedly connected with a suppressing clamping plate 20.

[0035] A further advantage of the above is that when the moving plate 7 moves to the appropriate position, the lifting motor 16 drives the lifting gear ring 14 to rotate the lifting spline hub 18 counterclockwise. The lifting spline hub 18 drives the ball spline 19 to descend vertically to the appropriate position. Then, the clamping motor 15 drives the synchronous gear ring 13 to rotate the clamping spline hub 17 synchronously counterclockwise. The clamping spline hub 17 drives the ball spline 19 to rotate synchronously. The ball spline 19 drives the suppressing clamping plate 20 to rotate synchronously. The suppressing clamping plate 20 clamps the hanging plate 10 from all sides, thereby suppressing the shaking of the hanging plate 10 due to inertia before assembly, which facilitates component assembly.

[0036] When this utility model is used, the wind turbine gearbox in the prior art is hoisted into the fixing groove 2, and the limiting rod 4 is inserted into the fixing ear of the wind turbine gearbox. Through the cooperation of the fixing groove 2 and the fixing ear, the wind turbine gearbox is positioned to support the assembly of internal parts.

[0037] During hoisting, the hoisting platform 10 is lowered to near the ground by the crane 9. The workers place the hoisting platform 10 on the upper surface of the part to be assembled. Then, the electromagnet 11 is energized, and the part to be assembled is attracted by magnetic force. When hoisting a gear with a gear shaft, the gear shaft can pass through the through hole opened in the center of the hoisting platform 10. At the same time, the gear body is in close contact with the electromagnet 11. Therefore, when hoisting this kind of gear shaft, there is no need to change the lifting tool, realizing the function of hoisting multiple parts and improving the assembly efficiency.

[0038] During assembly, the hoist 9 pulls the suspended platform 10 up to near the movable platform 7. The movable motor 6 drives the lead screw 5 to rotate, which in turn drives the movable platform 7 to slide along the limit rod 4 to directly above the fixed groove 2, aligning the suspended platform 10 with the wind turbine gearbox in the fixed groove 2. After the movable platform 7 has moved, the lifting motor 16 drives the lifting gear ring 14 to rotate the lifting spline hub 18 counterclockwise. The lifting spline hub 18 drives the ball spline 19 to descend vertically until the inhibiting clamp 20 is aligned with the suspended platform 10. Then, the clamping motor 15 drives the synchronous gear ring 13 to move the clamping spline hub 19. The 7-drive synchronous counterclockwise rotation drives the ball spline 19 to rotate synchronously through the clamping spline hub 17. The ball spline 19 drives the suppressing clamp 20 to rotate synchronously. The suppressing clamp 20 clamps the hanging plate 10 from all sides, thereby suppressing the swaying of the hanging plate 10 due to inertia before assembly. After the hanging plate 10 stops swaying, the clamping motor 15 drives the synchronous gear ring 13 to rotate in the opposite direction, causing the ball spline 19 to drive the suppressing clamp 20 to rotate and unfold. Then, the crane 9 pulls the hanging plate 10 down into the wind turbine gearbox for assembly by workers. This achieves the function of suppressing swaying and further improves the assembly efficiency.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
