Description

Technical Field

[0001] This invention relates to the field of wind turbine ring rolling technology, and in particular to a wind turbine ring rolling equipment and its operating method for preventing edge collapse. Background Technology

[0002] Regarding the rolling forming of rings, in the prior art, Chinese patent with publication number CN102489638B discloses a method for axial rolling forming of a large inner stepped ring, including the following steps: (1) billet preparation: hot forging, upsetting, punching, and punching the connecting skin of the bar stock to make a ring blank for rolling; (2) rolling pass design: the rolling pass size is determined according to the rolling line speed, equipment parameters, rolling deformation conditions, and ring blank size, and the axial rolling pass size is determined by the rolling line speed, equipment parameters, ring blank and ring size; (3) rolling forming: the prepared ring blank is placed on a ring rolling mill for rolling, and the upper and lower tapered rollers are controlled to retreat in real time during the rolling process so that the bottom end always keeps in contact with the outer diameter of the upper and lower end faces of the ring. The rolling process is controlled by reasonably allocating the feed speed and feed amount according to the three stages of pre-rolling, main rolling and shaping rolling. When the measured outer diameter of the ring reaches the predetermined value, the rolling process ends.

[0003] While the aforementioned patents have solved the problems of low production efficiency, high costs, and poor product quality, they still have the following drawbacks;

[0004] 1. Before rolling, the ring blank needs to be raised and fitted onto the main roll and core roll, which requires the addition of mechanical equipment to control the rise or fall of the wind turbine ring, thus increasing equipment costs.

[0005] 2. During rolling, the main roll and the mandrel are controlled by separate power sources. The movement of the main roll and the mandrel is controlled by different programs, which increases the requirements for program control. Summary of the Invention

[0006] The purpose of this invention is to provide a rolling equipment and operating method for anti-collapse wind turbine ring components to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rolling device for anti-collapse wind turbine ring components, comprising a rolling box installed on a support platform, a rolling platform installed at the top opening of the rolling box, and a hollow cavity formed inside the rolling box and the rolling platform;

[0008] The rolling platform has a rolling hole at its center that communicates with the chamber, and the limiting component is embedded in the rolling hole.

[0009] The rolling mill is equipped with a lifting power component that extends into the limiting component. The rotating component connected to the lifting power component is located inside the limiting component. The claw component movably connected to the rotating component moves up and down at the top of the limiting component. The claw component is used to change the inner and outer diameters of the wind turbine ring.

[0010] The rolling platform is equipped with a pressure roller assembly on its top surface outside the rolling hole, which is used to adjust the thickness of the wind turbine ring component.

[0011] Furthermore, the limiting assembly includes a limiting shell, a support frame, a battery, and a control box. The limiting shell is embedded in the rolling hole, and the bottom end of the limiting shell extends into the cavity. Several support frames are provided and fixed to the bottom wall of the rolling platform along the radial direction of the limiting shell.

[0012] The battery and control box are installed inside the rolling mill, which also has a double door on the front.

[0013] Furthermore, the lifting power assembly includes a lower cylinder, a lifting rod, a support plate, a guide ring, and a guide rod. The lower cylinder is installed on the bottom wall of the rolling mill. One end of the lifting rod is connected to the piston rod of the lower cylinder, and the other end of the lifting rod is inserted into the limiting shell and fixed to the bottom wall of the support plate. Several guide rings are fixed on the edge of the support plate. The guide rings are sleeved on the guide rod, and the guide rod is fixed to the bottom wall of the rolling mill.

[0014] Furthermore, the rotating assembly includes a turntable, a helical track, a gear ring, and a rotary motor. The turntable and the support plate are movably connected by a slewing bearing. The turntable has helical tracks distributed on it, and a gear ring is fitted on the side circumference of the helical tracks. The rotary motor is mounted on the bottom wall of the support plate, and a gear that meshes with the gear ring is mounted on the shaft of the rotary motor that passes through the support plate.

[0015] Furthermore, the top surface of the limiting shell is provided with equally spaced sliding channels, and the sliding channels are connected to the interior of the limiting shell.

[0016] Furthermore, the chuck assembly includes a chuck clamp, an arc plate, an inner rotating shaft, an outer rotating shaft, a longitudinal motor, a slider, and a lead screw. The chuck clamp is inserted into the sliding groove, and the arc plate connected to the bottom of the chuck clamp is inserted into the spiral track.

[0017] Each of the outer and inner rotating shafts is inserted into a slider. The inner rotating shaft is connected to a servo motor for driving. The slider is locked in a groove at the top of the jaw clamp. The longitudinal motor is set in a groove in the jaw clamp. The shaft of the longitudinal motor is connected to one end of a lead screw. The lead screw has symmetrical threads on both sides. The symmetrical threads on both sides of the lead screw respectively mesh with the sliders of the outer and inner rotating shafts, for the outer and inner rotating shafts to move towards each other or in opposite directions.

[0018] Furthermore, the inner wall of the spiral track is provided with a T-shaped groove, and the groove block on the side of the arc plate is inserted into the T-shaped groove, so that the spiral track and the chuck clamp rise or fall synchronously.

[0019] Furthermore, the pressure roller assembly includes a pressure roller, a first cylinder, and a second cylinder. The first cylinder is mounted on the rolling platform, and the second cylinder is connected to the piston rod of the first cylinder. The piston rod of the second cylinder is connected to the pressure roller for adjusting the position of the pressure roller.

[0020] Another technical solution proposed in this invention includes an operation method for an anti-collapse edge wind turbine ring rolling equipment, comprising the following steps:

[0021] S1: Before production, the lower cylinder drives the support plate to descend until the top surfaces of the inner and outer rotating shafts are aligned with the top surface of the rolling platform. The longitudinal motor drives the lead screw to rotate until the inner and outer rotating shafts move to their maximum positions in opposite directions and then stops. The pressure roller is also adjusted to its highest position.

[0022] S2: The wind turbine ring is placed on the rolling platform. The inner rotating shaft is located directly below the central through hole of the wind turbine ring. The lower cylinder drives the support plate to rise. The wind turbine ring was originally located between the inner and outer rotating shafts. The longitudinal motor drives the lead screw to rotate in the opposite direction. The inner and outer rotating shafts move in opposite directions and clamp the inner and outer sides of the wind turbine ring. The pressure roller moves to press on the wind turbine ring.

[0023] S3: The rotary motor drives the gear to rotate, which in turn drives the spiral track to rotate. Multiple sets of chucks move outward synchronously. The inner rotating shaft also rotates, which drives the wind turbine ring component to rotate. The inner and outer rotating shafts slowly move outward to change the inner and outer diameters of the wind turbine ring component. The pressure roller follows the rotation of the wind turbine ring component, and the thickness of the wind turbine ring component is changed by the degree of descent of the pressure roller.

[0024] S4: The inner and outer rotating shafts change the width of the wind turbine ring by moving in opposite directions or in opposite directions;

[0025] S5: When the inner and outer diameters and thickness of the wind turbine ring reach the set values, rolling stops and the support plate descends, allowing the wind turbine ring to be directly removed.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. In the present invention, when the rolling platform is in a horizontal state before rolling, the wind turbine ring can be directly pushed onto the top of the claw assembly, avoiding the need to add equipment that can clamp and lift the wind turbine ring, thus avoiding the increase in equipment cost.

[0028] 2. The inner and outer rotating shafts of this invention can move synchronously outward or inward with the chucks, or they can move relative to each other, thus providing a wider range of adjustment. Compared with existing methods that only move outward or inward through a single axis, this invention offers a higher degree of control. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] To address the issue in existing technologies where the ring blank needs to be raised and fitted onto the main roll and core roll before rolling, which requires additional mechanical equipment to control the raising or lowering of the wind turbine ring and increases equipment costs, the following technical solution is provided. Please refer to [link / reference]. Figure 1-7 ;

[0039] A wind turbine ring rolling device for preventing edge collapse includes a rolling box 2 installed on a support platform 1, a rolling platform 3 installed at the top opening of the rolling box 2, and a hollow chamber formed inside the rolling box 2 and the rolling platform 3.

[0040] A rolling hole 31 communicating with the chamber is provided at the center of the rolling platform 3, and the limiting component 4 is embedded in the rolling hole 31.

[0041] The rolling box 2 is provided with a lifting power component 5 extending into the limiting component 4. The rotating component 6 connected to the lifting power component 5 is located inside the limiting component 4. The claw component 7 movably connected to the rotating component 6 moves up and down at the top of the limiting component 4. The claw component 7 is used to change the inner diameter and outer diameter of the wind turbine ring.

[0042] A pressure roller assembly 8 is installed on the top surface of the rolling platform 3 outside the rolling hole 31, which is used to adjust the thickness of the wind turbine ring component.

[0043] The limiting assembly 4 includes a limiting shell 41, a support frame 42, a battery 43, and a control box 44. The limiting shell 41 is embedded in the rolling hole 31, and the bottom end of the limiting shell 41 penetrates into the cavity. Several support frames 42 are provided and are fixed on the bottom wall of the rolling platform 3 along the radial direction of the limiting shell 41.

[0044] The storage battery 43 and the control box 44 are installed inside the rolling mill 2, and the front of the rolling mill 2 is also provided with a double door.

[0045] The lifting power assembly 5 includes a lower cylinder 51, a lifting rod 52, a support plate 53, a guide ring 54, and a guide rod 55. The lower cylinder 51 is installed on the bottom wall of the rolling mill 2. One end of the lifting rod 52 is connected to the piston rod of the lower cylinder 51, and the other end of the lifting rod 52 is inserted into the limiting shell 41 and fixed to the bottom wall of the support plate 53. Several guide rings 54 are fixed on the edge of the support plate 53. The guide rings 54 are sleeved on the guide rods 55, and the guide rods 55 are fixed to the bottom wall of the rolling mill 2.

[0046] The rotating assembly 6 includes a turntable 61, a spiral track 62, a gear ring 63, and a rotary motor 64. The turntable 61 is movably connected to the support plate 53 via a slewing bearing. The spiral track 62 is distributed on the turntable 61, and the gear ring 63 is fitted on the side circumference of the spiral track 62. The rotary motor 64 is mounted on the bottom wall of the support plate 53, and a gear that meshes with the gear ring 63 is mounted on the shaft of the rotary motor 64 that passes through the support plate 53.

[0047] The top surface of the limiting shell 41 is provided with equally spaced sliding channels, and the sliding channels are connected to the interior of the limiting shell 41.

[0048] Specifically, before assembly, the lower cylinder 51 drives the support plate 53 to descend along the guide rod 55. During the descent of the support plate 53, the spiral track 62 has a T-slot on its inner wall. The slot block on the side of the arc plate 72 is inserted into the T-slot. The spiral track 62 and the claw clamp 71 rise or fall synchronously. This allows the top ends of the inner rotating shaft 73 and the outer rotating shaft 74 to retract into the rolling platform 3 when not in rolling, so that the top surface of the rolling platform 3 is in a horizontal state. The wind turbine ring can then be directly pushed onto the claw assembly 7, avoiding the need for additional equipment to hold the wind turbine ring and lift it, which would increase the cost of the equipment, as required by the existing technology that only allows the wind turbine ring to be placed on the rotating shaft from top to bottom.

[0049] Furthermore, this equipment utilizes the structure of the guide ring 54 and the guide rod 55 to ensure that the support plate 53 remains stable during the lifting process. At the same time, the guide rod 55 shares the pressure of the lifting rod 52, preventing the lifting rod 52 from bending during long-term use.

[0050] In order to address the problem that in the existing technology, the main roll and the mandrel are controlled by separate power during rolling, and the movement of the main roll and the mandrel is controlled by different programs, which increases the control requirements of the programs, the following technical solution is proposed.

[0051] The claw assembly 7 includes a claw clamp 71, an arc plate 72, an inner rotating shaft 73, an outer rotating shaft 74, a longitudinal motor 75, a slider 76, and a lead screw 77. The claw clamp 71 is inserted into the sliding groove, and the arc plate 72 connected to the bottom of the claw clamp 71 is inserted into the spiral track 62.

[0052] An outer rotating shaft 74 and an inner rotating shaft 73 each insert a slider 76. The inner rotating shaft 73 is connected to a servo motor with a drive mechanism. The slider 76 is locked in a groove at the top of the jaw clamp 71. A longitudinal motor 75 is set in a groove in the jaw clamp 71. The shaft of the longitudinal motor 75 is connected to one end of a lead screw 77. The lead screw 77 has symmetrical threads on both sides. The symmetrical threads on both sides of the lead screw 77 mesh with the sliders 76 of the outer rotating shaft 74 and the inner rotating shaft 73, respectively, for the outer rotating shaft 74 and the inner rotating shaft 73 to move towards each other or in opposite directions.

[0053] Specifically, the arc plates 72 of multiple sets of jaw clamps 71 are inserted into the spiral track 62. When the rotary motor 64 starts, the spiral track 62 rotates clockwise or counterclockwise with the gear ring 63. As the spiral track 62 rotates, the arc plates 72 slide along the sliding groove, and the multiple sets of jaw clamps 71 also slide along the sliding groove. The distance that the multiple sets of jaw clamps 71 slide outward or inward is the same. Then, the outer rotating shaft 74 and the inner rotating shaft 73 on each jaw clamp 71 move outward or inward with the jaw clamp 71. During the movement, the inner rotating shaft 73 drives the wind turbine component to rotate, and the force of the inner rotating shaft 73 moving outward causes the inner diameter of the wind turbine component to continuously increase. During the rolling process, the outer rotating shaft 74 is used to limit the position of the wind turbine component.

[0054] The inner rotating shaft 73 and the outer rotating shaft 74 can move outward or inward synchronously with the chuck 71, or they can move relative to each other, thus providing a wider range of adjustment. Compared with existing systems that only move outward or inward through a single axis, the degree of control is higher.

[0055] The pressure roller assembly 8 includes a pressure roller 81, a first cylinder 82, and a second cylinder 83. The first cylinder 82 is mounted on the rolling platform 3. The second cylinder 83 is connected to the piston rod of the first cylinder 82. The piston rod of the second cylinder 83 is connected to the pressure roller 81 and is used to adjust the position of the pressure roller 81.

[0056] To better demonstrate the operation process of the anti-collapse wind turbine ring rolling equipment, this embodiment proposes an operation method for the anti-collapse wind turbine ring rolling equipment, including the following steps:

[0057] Step 1: Before production, the lower cylinder 51 drives the support plate 53 to descend until the top surfaces of the inner rotating shaft 73 and the outer rotating shaft 74 are aligned with the top surface of the rolling platform 3. The longitudinal motor 75 drives the lead screw 77 to rotate until the inner rotating shaft 73 and the outer rotating shaft 74 move to their maximum positions in opposite directions and then stop. The pressure roller 81 is also adjusted to its highest position.

[0058] Step 2: The wind turbine ring is placed on the rolling platform 3. The inner rotating shaft 73 is located directly below the central through hole of the wind turbine ring. The lower cylinder 51 drives the support plate 53 to rise. The wind turbine ring is originally located between the inner rotating shaft 73 and the outer rotating shaft 74. The longitudinal motor 75 drives the lead screw 77 to rotate in the opposite direction. The inner rotating shaft 73 and the outer rotating shaft 74 move in opposite directions and clamp the inner and outer sides of the wind turbine ring. The pressure roller 81 moves to press on the wind turbine ring.

[0059] Step 3: The rotary motor 64 drives the gear to rotate, which in turn drives the spiral track 62 to rotate. Multiple sets of chucks 71 move outward synchronously. The inner rotating shaft 73 also rotates, which drives the wind turbine ring component to rotate. The inner rotating shaft 73 and the outer rotating shaft 74 slowly move outward to change the inner and outer diameters of the wind turbine ring component. The pressure roller 81 follows the rotation of the wind turbine ring component. The thickness of the wind turbine ring component is changed by the degree of descent of the pressure roller 81.

[0060] Step 4: The inner rotating shaft 73 and the outer rotating shaft 74 change the width of the wind turbine ring by moving in opposite directions or in opposite directions;

[0061] Step 5: When the inner and outer diameters and thickness of the wind turbine ring reach the set values, rolling is stopped, and the support plate 53 descends, allowing the wind turbine ring to be directly removed.

[0062] In summary, the anti-collapse edge wind turbine ring rolling equipment and its operating method of the present invention, when not rolling, allow the top ends of the inner rotating shaft 73 and the outer rotating shaft 74 to retract into the rolling platform 3, making the top surface of the rolling platform 3 horizontal. This allows the wind turbine ring to be directly pushed onto the claw assembly 7, avoiding the need for additional equipment to hold and lift the wind turbine ring, which increases equipment costs, as required by the prior art where the wind turbine ring can only be placed on the rotating shaft from top to bottom. The arc plates 72 of multiple sets of claw clamps 71 are inserted into the spiral track 62. When the rotating motor 64 starts, the multiple sets of claw clamps 71 slide the same distance outward or inward. The inner rotating shaft 73 and the outer rotating shaft 74 can move synchronously outward or inward with the claw clamps 71, or they can move relative to each other, thus providing a wider adjustment range. Compared to the existing method of moving only a single axis outward or inward, this method offers a higher degree of control.

[0063] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
