Description

Technical Field

[0001] The invention relates to drilling holes in a generator nacelle, in particular to a wind turbine nacelle processing device. Background Art

[0002] The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of wind, converting the kinetic energy of the wind into mechanical energy of the wind rotor shaft. The generator rotates and generates electricity driven by the wind rotor shaft.

[0003] Usually, the cabin cover of a wind turbine, also known as the wind turbine nacelle, is usually a cylindrical structure during production. After production, it is fixed to the pillar with bolts through the fixing holes. However, the fixing holes on the wind turbine nacelle are mostly distributed in a circle. However, when drilling holes in a circular distribution, it is easy to have inconsistent spacing between adjacent fixing holes. In addition, when drilling holes in a circular distribution, a rotating rod is usually used to drive the drill bit to rotate with the other end of the rotating rod as the center of the circle to perform circular distribution drilling on the casing. However, it is difficult to accurately place the wind turbine nacelle and one end of the center of the rotating rod coaxially, resulting in asymmetric drilling. Summary of the invention

[0007] Preferably, the center positioning assembly includes a sliding assembly and a traction and rotation assembly, the sliding assembly is arranged on the placement assembly, and the traction and rotation assembly is arranged on the sliding assembly.

[0008] Preferably, the sliding assembly includes a plurality of support rods arranged on the extrusion plate, ball bearings rotatably arranged on the top ends of the support rods, and a placement plate abutting against the ball bearings. A limiting groove abutting against the ball bearings is provided on the lower side of the placement plate, and the generator compartment cover is placed on the placement plate.

[0009] Preferably, the traction and rotation group includes a first fixed rod that slides through the placement plate and the extrusion plate and is connected to the base, a plurality of telescopic rods fixed at edge positions of the first fixed rod, and an extrusion block connected to one end of the telescopic rod.

[0010] Preferably, a rotating ring is provided on the outer side of the first fixed rod through a bearing sleeve, a traction ring is connected to the outer side of the rotating ring through multiple third fixed rods, a limit rod is connected to the movable end of the telescopic rod, and a limit hole is provided on the traction ring on the outer side of the limit rod, so that the traction ring can synchronously drive the multiple telescopic rods to contract or separate when the traction ring rotates, a traction rod is connected to the lower end of the traction ring through a universal joint, and the other end of the traction rod is connected to the extrusion plate through a universal joint.

[0011] Preferably, the rotary drilling assembly includes a hydraulic cylinder embedded in the top of a first fixed rod, a rotating tube arranged at the top of the hydraulic cylinder through a bearing, and a rotating plate sleeved and fixed on the outside of the rotating tube, a first driving motor is provided at the other end of the rotating plate, and a drill bit is connected to the rotating plate that rotates through the output end of the first driving motor.

[0012] Preferably, one end of the hydraulic cylinder is connected to a second drive motor, an output end of the second drive motor is connected to a bevel gear 1, and one end of the rotating tube is connected to a bevel gear 2 meshing with the bevel gear 1.

[0013] Preferably, the rotation positioning assembly includes a fixing ring connected to the first fixing rod via a second fixing rod, a plurality of sliding rods slidingly passing through the fixing ring, and a rotating rod connected to the bottom end of the rotating tube.

[0014] Preferably, the bottom end of the sliding rod is connected to a first electromagnet, the outer side of the sliding rod is sleeved with a spring respectively connected to the first electromagnet and a fixed ring, the fixed end of the hydraulic cylinder is connected to a second electromagnet sleeved on the outside of the telescopic end of the hydraulic cylinder, the top end of the sliding rod is connected to a fan-shaped plate that can resist the rotating rod, and a plurality of the fan-shaped plates are arranged in a circular array.

[0015] The advantages of the present invention compared with the prior art are:

[0016] When the wind turbine generator cabin cover is placed on the placement plate, the placement plate can be driven downward by the deadweight of the generator cabin cover, thereby driving the compression of the elastic telescopic rod, and then the traction of the traction ring by the traction rod is used to rotate the traction ring, and slide on the outside of the limit rod through the limit hole, thereby driving the limit rods on the multiple telescopic rods to slide synchronously away from each other, so that the multiple extrusion blocks are synchronously against the wind turbine generator cabin cover, so that the generator cabin cover and the placement plate slide at the same time, so that the center of the generator cabin cover is coaxial with the first fixed rod, and the rotating end of the rotating plate is coaxial with the center of the generator cabin cover, so as to facilitate automatic adjustment of the generator cabin cover after placement, and facilitate to improve the position of the fixed hole drilling on the generator cabin cover to be more accurate and symmetrical;

[0017] When drilling a fixed hole on the generator compartment cover by rotating the rotating plate, when the rotating rod rotates and abuts against the fan-shaped plate, as the rotating rod moves downward, the drill bit moves downward steadily to drill a hole. After the rotating tube moves downward to push the sliding rod downward, the first electromagnet and the second electromagnet are fixed, so that the sliding rod moves downward and is fixed. After a single hole is drilled, the rotating rod is moved upward to rotate. Since the sliding rod has been moved downward and fixed, the rotating rod can continue to rotate and abut against another fan-shaped plate, so that the distance between adjacent holes is limited, avoiding the situation where the distances between adjacent holes are different, and the operation of the drill bit moving downward and rotating can automatically limit and cancel the limit.

[0018] 3. By controlling the opening quantity and strength of the first electromagnet, the number of holes punched in the fixing holes is adjusted to facilitate personalized drilling. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In some specific embodiments, the bottom end of the sliding rod 503 is connected to a first electromagnet 504, the outer side of the sliding rod 503 is sleeved with a spring 505 respectively connected to the first electromagnet 504 and the fixing ring 501, the fixed end of the hydraulic cylinder 401 is connected to a second electromagnet 506 sleeved on the outer side of the telescopic end of the hydraulic cylinder 401, and the top end of the sliding rod 503 is connected to a fan-shaped plate 507 that can resist the rotating rod 502, and a plurality of the fan-shaped plates 507 are arranged in a circular array.

[0043] In some specific embodiments, the rotating plate 403 is set as a telescopic structure, specifically including a sleeve plate 4031, an electric push rod 4032 and a sliding plate 4033. The sleeve plate 4031 is sleeved on the outside of the sliding plate 4033, and the electric push rod 4032 is set in the sleeve plate 4031 to enable the sliding of the sliding plate 4033 to enable the rotating plate 403 to realize the telescopic function, which is convenient for extending and retracting the rotating plate 403 when placing or removing the generator compartment cover 1.

[0044] In some specific embodiments, a controller is also provided for controlling various devices in the present application.

[0045] The specific implementation process is as follows:

[0046] In Example 1, when placing the generator compartment cover 1, the drill bit 405 is moved toward the direction of the hydraulic cylinder 401 by extending and retracting the rotating plate 403, and the generator compartment cover 1 that needs to be drilled is lifted and placed on the placement plate 3013 by an external lifting device, so that the center of the generator compartment cover 1 is as coaxial as possible with the first fixing rod 3021 and the hydraulic cylinder 401, and the limiting groove 3014 on the lower side of the placement plate 3013 can slide on the outside of the ball 3012 through the action of the ball 3012, and the placement plate 3013 is driven downward by the dead weight of the generator compartment cover 1, and the elastic telescopic rod 302 is compressed in cooperation with the ball 3012, and then the traction rod 3012 is used to pull the generator compartment cover 1 to the bottom of the placing plate 3013. 027 The traction of the traction ring 3024 causes the traction ring 3024 to rotate outside the first fixing rod 302, slide outside the limiting rod 3025 through the limiting hole 3026, and then drive the limiting rods 3025 on the multiple telescopic rods 3022 to slide synchronously, so that the multiple extrusion blocks 3023 are synchronously abutted against the wind turbine nacelle 1, so that the generator nacelle 1 and the placement plate 3013 slide simultaneously, so that the center of the generator nacelle 1 is coaxial with the first fixing rod 3021, and the rotating end of the rotating plate 403 is coaxial with the center of the generator nacelle 1, so as to facilitate automatic adjustment of the generator nacelle 1 after placement, and facilitate to improve the position of the drilling of the fixing hole 101 on the generator nacelle 1 to be more accurate and symmetrical;

[0047] After the generator compartment cover 1 is placed, the drilling operation begins. The rotating plate 403 is adjusted to be retracted by controlling the electric push rod 4032, and the drill bit 405 is adjusted to a suitable position on the generator compartment cover 1. The drill bit 405 is driven to rotate by turning on the first drive motor 404 to facilitate drilling. The first electromagnet 504 and the second electromagnet 506 are turned on as needed. The first electromagnet 504 is subjected to the attraction and gravity between the first electromagnet 504 and the second electromagnet 506 and the tension of the spring 505. At this time, the force of the first electromagnet 504 is balanced, and the first electromagnet 504 and the second electromagnet 506 are just suspended in the air. By turning on the rotation of the second drive motor 406, the rotating tube 402 is driven to rotate in coordination with the bevel gear 1 and the bevel gear 2, and then the rotating plate 403 and the rotating rod 502 are driven to rotate. The rotating plate 403 is rotated to align the drill bit 405 with the position where drilling is required. When the rotating rod 502 rotates and the fan-shaped plate 507 is abutted to limit, the second drive motor 406 is turned off, and the hydraulic cylinder 4 is controlled to rotate. 01 makes the rotating plate 403 and the rotating rod 502 move downward, and the rotating plate 403 moves downward to make the drill bit 405 move downward to drill a hole in the generator compartment cover 1, and the rotating rod 502 moves downward in the fan-shaped plate 507 to squeeze the sliding rod 503 downward, thereby driving the first electromagnet 504 and the second electromagnet 506 to attract and fix when they are against each other. Since the attraction between the first electromagnet 504 and the second electromagnet 506 is the largest when they are against each other, the pulling force of the spring 505 is overcome. After drilling, as the rotating rod 502 moves upward, The sliding rod 503 will not move upward, and the downwardly moved sector plate 507 will no longer abut against the rotating rod 502. When drilling a hole at the next position, the second driving motor 406 is turned on to drive the rotating rod 502 to rotate and abut against another sector plate 507 that has not moved downward. The above operation is repeated to continue drilling until a circle of holes on the generator compartment cover 1 is drilled. The circular array drilling is achieved by setting a plurality of sliding rods 503 in a circular array, so that the spacing between the fixed holes 101 of the drilling holes is consistent.

[0048] After the drilling is completed, the first electromagnet 504 and the second electromagnet 506 are turned off, so that the first electromagnet 504 and the second electromagnet 506 are separated and reset.

[0049] In Example 2, the first electromagnet 504 has two gears when it is turned on. In the first gear, the magnetic force generated by the first electromagnet 504 is relatively small to implement the solution in Example 1. In the second gear, one or more first electromagnets 504 are individually controlled to generate a larger magnetic field, which can be directly attracted to the second electromagnet 506 and will not be suspended in the air, so that the drill bit 405 corresponding to the corresponding first electromagnet 504 will not drill holes when drilling, so that the number and position of holes to be drilled can be adjusted according to needs.

[0050] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art.
