Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine blade processing, and in particular to a supporting device for processing and forming wind turbine blades. Background Art

[0002] In the current production process of wind turbine blades, glass fiber is usually laid throughout the mold and filled with resin. During the filling process, the blade mold is driven to deflect by a clamping device to accelerate the flow of resin, making the resin filling more uniform and rapid. In the manufacturing process of 100-meter-class blades, due to the long length of the blade mold, the clamping device is used to clamp and deflect the blade end, which causes excessive force on the distal blade, and the internal structure is easily deformed, so it is not convenient to assist the flow of resin by deflection; and the 100-meter-class blades are long and thick, so they need to be lifted to a certain height during the manufacturing process, making it inconvenient for operators to operate the manual working platforms on both sides of the mold, and when manufacturing extra-long blades, after the mold is deflected, the up and down displacement of the two ends is large, and the manual platform cannot follow the operation. If the platform follows the deflection, a slope is formed, which is also inconvenient for operators to operate.

[0003] Therefore, the present application designs a support device for wind turbine blade processing and forming that can deflect and lift the membrane mold and simultaneously drive the membrane mold to rise or fall by switching, and the accompanying artificial platform can be modularly stepped. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0035] like Figures 1 to 12As shown, the present application proposes a support device for wind turbine blade processing and forming, comprising an array support mechanism 1, an array lifting mechanism 2, and a modular artificial platform 3 that can be synchronously deformed in a step-like manner with the inclination of the array lifting mechanism 2; the support mechanism 1 is arranged vertically along the same horizontal direction, the lower end of the support mechanism 1 is connected to the ground with bolts, the lifting mechanism 2 is arranged in the middle of the support mechanism 1, the upper end of the support mechanism 1 is clamped with the blade mold, the lower end of the modular artificial platform 3 is connected to the ground with bolts, and the two ends of the modular artificial platform 3 are connected to the support mechanism 1 at both ends with limited rotation; the array lifting mechanism 2 lifts or lowers the upper part of the support mechanism 1 differently through its own relative displacement to make the blade mold tilt;

[0036] A telescopic electromagnetic pin 4 is provided in the lifting mechanism 2. The telescopic electromagnetic pin 4 is extended and retracted through electromagnetic triggering to switch and drive different gears, so that the array lifting mechanism 2 is switched to a synchronous lifting or lowering form to change the overall height of the blade mold. The modular artificial platform 3 is deformed in a step-like manner through the inclination caused by the array lifting mechanism 2 to adapt to the inclination angle of the blade mold.

[0037] As another example, Figures 2 to 9 As shown, the support mechanism 1 includes a fixed lower plate 11, an upper plate 12 and an arc-shaped support plate 13. The lower end of the fixed lower plate 11 is connected to the ground bolts, the upper end of the fixed lower plate 11 is connected to the lower end of the lifting mechanism 2 with a damped rotation through a triangular plate, and the lower part of the upper plate 12 is connected to the upper end of the lifting mechanism 2 with a damped rotation; the two ends of the upper plate 12 are connected to the two sides of the arc-shaped support plate 13 with a damped rotation, and the upper end of the arc-shaped support plate 13 is slidably engaged with the blade mold.

[0038] In the initial state, the upper end of the support mechanism 1, i.e., the arc-shaped support plate 13, is in the same horizontal plane. After the blade mold is installed on the arc-shaped support plate 13, the manufacturing construction of the wind turbine blade can be carried out. When the blade mold needs to be offset to assist the resin flow, the lifting mechanism 2 on one side rises and the lifting mechanism 2 on the other side falls with the center point of the blade mold as the boundary. The displacement distance of the lifting mechanisms 2 at both ends is the longest, and the displacement distance of the lifting mechanisms 2 gradually decreases as they are closer to the middle of the blade mold, so that the blade mold presents a slight circular rotation trend with the middle as the axis. The arc-shaped support plate 13 naturally rotates relative to the upper plate 12 as the blade mold deflects to adapt to the shape of the blade mold. The sliding engagement between the blade mold and the arc-shaped support plate 13 can adapt to the slight displacement of the blade mold during deflection.

[0039] The size and style of the arc-shaped slots of the arc-shaped support plate 13 match the shape of the blade mold at the supporting position.

[0040] See also Figures 2 to 4The lifting mechanism 2 includes two groups of parallel arranged diamond lifters 21; the lower end of the diamond lifter 21 is connected to the fixed lower plate 11 with a damped rotation through a triangular plate, and the upper end of the diamond lifter 21 is connected to the lower end of the upper plate 12 with a damped rotation; a threaded drive rod 211 is provided in the middle of the diamond lifter 21, and a hinge pin 212 is provided at the hinge of the diamond lifter 21, and an internal thread is provided in the hinge pin 212. The threaded drive rod 211 is threadedly connected to the hinge pin 212, and the threaded drive rod 211 passes through the two groups of diamond lifters 21.

[0041] When the blade mold needs to be deflected or lifted and lowered as a whole, the threaded drive rod 211 rotates, causing the hinge pin 212 threadedly connected to it to move horizontally relative to the blade mold, thereby driving the diamond lifter 21 to expand or contract, driving the upper plate 12 and the arc-shaped support plate 13 at the upper end to rise or fall. The two groups of diamond lifters 21 are provided to enhance the structural strength and prevent the center of gravity from shifting.

[0042] Among them, it is very critical that the internal threads of the two groups of hinge pins 212 are in opposite directions, four sections of threads are arranged on the threaded drive rod 211, and the thread directions of the two groups of adjacent threads are in opposite directions; the threads in the lifting mechanisms 2 at both ends are in opposite directions and the thread spacing is the largest, and the thread spacing of the lifting mechanisms 2 closer to the middle gradually decreases; the internal threads of the two symmetrical groups of lifting mechanisms 2 are in opposite directions.

[0043] Taking 6 groups of lifting mechanisms 2 as an example, the thread directions of the three groups of threaded drive rods 211 and hinge pins 212 on the left are opposite to those of the three groups of threaded drive rods 211 and hinge pins 212 on the right. The thread spacing of the three groups of threaded drive rods 211 and hinge pins 212 on the left decreases from left to right, and the thread spacing of the three groups of threaded drive rods 211 and hinge pins 212 on the right decreases from right to left, so that when all the threaded drive rods 211 rotate at the same speed, the movement directions of the two symmetrical groups of lifting mechanisms 2 are opposite, and the displacement of the blade mold by each group of lifting mechanisms 2 is different, so that the blade mold shows a movement trend of circular motion with the center point as the axis to assist the flow of resin.

[0044] See also Figure 2 as well as Figure 5The lifting mechanism 2 also includes a motor 22, a worm 23, a worm wheel 24, a telescopic rotating rod 25, a universal joint 26, a driving component A27 and a driving component B28; the motor 22 is connected to the ground bolt, the output end of the motor 22 is plugged into the worm 23, the worm 23 passes through all the fixed lower plates 11 and is rotatably connected to the fixed lower plates 11, the lower end of the worm wheel 24 is rotatably connected to the inner wall of the fixed lower plate 11, the worm 23 is meshed with the worm wheel 24, one end of the universal joint 26 is plugged into the end of the threaded driving rod 211, the other end of the universal joint 26 is plugged into the upper end of the telescopic rotating rod 25, the lower ends of all the telescopic rotating rods 25 of the lifting mechanism 2 on one side are plugged into the driving component A27, the lower ends of all the telescopic rotating rods 25 of the lifting mechanism 2 on the other side are plugged into the driving component B28, and the lower end of the telescopic electromagnetic pin 4 is plugged into the worm wheel 24.

[0045] Among them, the driving component A27 is entirely used for the lifting mechanism 2 on one side. The function of the driving component A27 is to reverse the rotation of the telescopic rotating rod 25 and accelerate or decelerate after starting the telescopic electromagnetic pin 4. The degree of acceleration or deceleration depends on the size of the intermediate wheel A273. The function of the driving component B28 is to only accelerate or decelerate the telescopic rotating rod 25 without changing the rotation direction, so that the lifting mechanism 2 on one side has the same displacement direction as the lifting mechanism 2 on the other side.

[0046] See also Figure 6 and Figure 7 The driving assembly A27 includes a driving wheel A271, a driven wheel A272, an intermediate wheel A273 and a housing A274; the driving wheel A271, the driven wheel A272 and the intermediate wheel A273 are all bevel gears, and the driving wheel A271, the driven wheel A272 and the intermediate wheel A273 are all rotatably connected to the inside of the housing A274, the driving wheel A271 is meshed with the intermediate wheel A273, and the intermediate wheel A273 is meshed with the driven wheel A272; the driving wheel A271 and the driven wheel A272 are both provided with a toothed slot, and a gear ring is provided on the surface of the telescopic electromagnetic pin 4. The telescopic electromagnetic pin 4 passes through the outer shell A274 and the driving wheel A271 and the driven wheel A272 are connected through the gear ring. The telescopic electromagnetic pin 4 is slidably connected to the inner wall of the outer shell A274, and the outer shell A274 is plugged into the fixed lower plate 11. The end of the telescopic rotating rod 25 away from the universal joint 26 passes through the fixed lower plate 11 and the outer shell A274 and is plugged into the driven wheel A272.

[0047] When the blade mold needs to be deflected, the telescopic electromagnetic pin 4 meshes with the driven wheel A272, the motor 22 drives the worm 23 to rotate, and then drives the worm wheel 24 to rotate, the rotation of the worm wheel 24 drives the telescopic electromagnetic pin 4 to rotate, and then directly drives the driven wheel A272 to rotate, and then drives the telescopic rotating rod 25 to rotate, and the rotation is transmitted to the threaded driving rod 211 through the universal joint 26, and finally the threads with different directions and spacings are used to make each rhombus lifter 21 expand or contract to different degrees, driving the blade mold to deflect;

[0048] When the blade mold needs to be lifted or lowered as a whole, the telescopic electromagnetic pin 4 is started to shrink, disengage from the driven wheel A272, and engage with the driving wheel A271. The telescopic electromagnetic pin 4 drives the driving wheel A271 to rotate, and then transmits the rotation to the driven wheel A272 through the intermediate wheel A273, so that the driven wheel A272 produces an acceleration or deceleration rotation in the opposite direction compared to the normal state, thereby driving the telescopic rotating rod 25 to rotate. By setting different sizes of the intermediate wheel A273, the threads of different pitches are compensated, so that all the diamond lifters 21 are synchronously expanded or contracted, thereby driving the blade mold to be lifted or lowered as a whole. The switching between lifting and lowering can be achieved by rotating the motor 22 in opposite directions.

[0049] Among them, inclined teeth can be set on the upper and lower sides of the gear ring on the telescopic electromagnetic pin 4 to facilitate the switching of the telescopic electromagnetic pin 4 between the driving wheel A271 and the driven wheel A272. The lower end of the telescopic electromagnetic pin 4 is connected to the outer shell A274 with a limited rotation. It adopts a double-layer pin structure and uses the upper outer layer for telescopic switching.

[0050] See also Figure 8 The driving assembly B28 includes a driving wheel B281, a driven wheel B282, an intermediate wheel B283 and a shell B284; the driving wheel B281, the driven wheel B282 and the intermediate wheel B283 are all rotatably connected to the inside of the shell B284, the upper part of the intermediate wheel B283 is meshed with the driven wheel B282, and the lower part of the intermediate wheel B283 is meshed with the driving wheel B281; the driving wheel B281 and the driven wheel B282 are both provided with a toothed slot, the telescopic electromagnetic pin 4 passes through the shell B284 and the driving wheel B281 and the driven wheel B282 are clamped by a gear ring, the telescopic electromagnetic pin 4 is slidably connected to the inner wall of the shell B284, the shell B284 is plugged into the fixed lower plate 11, and the end of the telescopic rotating rod 25 away from the universal joint 26 passes through the fixed lower plate 11 and is plugged into the shell B284 and the driven wheel B282.

[0051] Among them, the diameters of the driving wheel B281 and the driven wheel B282 are different, and the diameters of the upper and lower ends of the intermediate wheel B283 are different. When the blade mold needs to be deflected, the telescopic electromagnetic pin 4 directly engages with the driven wheel B282, and directly drives the telescopic rotating rod 25 to rotate through the driven wheel B282. When the overall lifting and lowering is performed, the telescopic electromagnetic pin 4 engages with the driving wheel B281, and transmits the rotation to the driven wheel B282 through the intermediate wheel B283. The rotation speed is changed by changing the intermediate wheels B283 of different sizes, so that the diamond lifter 21 can be expanded and contracted to the same extent. The difference between the driving component A27 and the driving component B28 is that different gear sets are used. The driving component A27 uses bevel gears and the intermediate wheels are perpendicular to the driving wheel and the driven wheel, so that the rotation is accelerated or decelerated while being reversed. The driving component B28 uses gears and the intermediate wheels are parallel to the driving wheel and the driven wheel, so that the rotation is only accelerated or decelerated, thereby making the lifting mechanisms 2 on both sides expand or contract at the same time.

[0052] As another example, Figure 1 as well as Figures 10 to 12 As shown, the modular artificial platform 3 includes an array platform 31, a support frame 32, a cross frame 33, a first rotating frame 34 and a second rotating frame 35; the modular artificial platform 3 is provided with two groups positioned on both sides of the support mechanism 1; the lower parts of the two ends of the platform 31 are respectively fixedly connected to the two groups of cross frames 33, the upper end of the support frame 32 is fixedly connected to the cross frame 33, the lower end of the support frame 32 is bolted to the ground, the side of the first rotating frame 34 is rotatably connected to one end of all the cross frames 33, the side of the second rotating frame 35 is rotatably connected to the other end of all the cross frames 33, and the first rotating frame 34 and the second rotating frame 35 close to one side of the arc-shaped support plate 13 are slidably and rotatably connected to the upper plates 12 at both ends.

[0053] When the blade mold is deflected, that is, the upper plates 12 of the support mechanisms 1 on both sides simultaneously move up and down, driving the first rotating frame 34 and the second rotating frame 35 to be displaced, so that the modular artificial platform 3 is unfolded. Under normal conditions, the platforms 31 are in the same horizontal position. After unfolding, the platforms 31 are parallel to each other but form a stepped arrangement tilted along the direction of the upper plate 12 as a whole. By connecting the first rotating frame 34 and the second rotating frame 35 respectively set with the two ends of the cross frame 33, the cross frame 33 is limited so that the cross frame 33 drives the platform 31 to be always horizontal without tilting, thereby making it easier for operators to carry out construction and operation; by the sliding and rotating connection between the first connecting frame, the second connecting frame and the upper plate 12, the modular platform 31 can adapt to the horizontal displacement caused by the offset of the first rotating frame 34 and the second rotating frame 35, and its sliding connection is provided with a large damping, so that operators or manpower cannot make it move, so as to ensure the safety of the modular artificial platform 3.

[0054] Referring to the figure, the horizontal frame 33 is an L-shaped structure, and the lower part of the platform 31 is fixedly overlapped on the upper part of the horizontal frame 33; if necessary, a protective frame can be set on the outer side of the modular artificial platform 3 to avoid the high-altitude fall of personnel or equipment to ensure the safety of the operators.

[0055] See also Figures 9 to 12 The support frame 32 is a telescopic frame, and the support frame 32 is provided with an array, which is respectively arranged at both ends and the middle of the modular artificial platform 3 to enhance the structural stability. The lower ends of the support frames 32 arranged at both ends are provided with lockable slide rails to assist the displacement of the support frames 32.

[0056] It should be noted that the telescopic structure of the support frame 32 is a lockable telescopic structure, which is unlocked only when the blade mold is deflected or displaced as a whole. It is automatically locked when the device is stationary to provide support for the modular artificial platform 3. The modular artificial platform 3 can be firmly supported by the connection between the first rotating frame 34, the second rotating frame 35 and the upper plate 12. The setting of the support frame 32 is only to further improve the support and structural stability.

[0057] Working principle:

[0058] When in use, first slide and snap the blade mold into place with the arc-shaped support plate 13, then the operator climbs onto the modular artificial platform 3 to start normal construction. When the blade mold needs to be deflected, the motor 22 is started, and two different drive components simultaneously drive the telescopic rotating rod 25 to rotate, and transmit the rotation to the spiral drive rod through the universal joint 26. Since the spiral drive rods and the hinge pin 212 of different groups of lifting mechanisms 2 have different thread directions and pitches, the lifting mechanism 2 on one side drives the blade mold to rise, and the other side drives the blade mold to fall, so that the blade mold can be lifted up. The blade mold is deflected to assist the flow of resin. The modular artificial platform 3 is driven by the displacement of the upper plate 12 to unfold and is arranged in a stepped manner along the inclination direction of the blade mold. When the blade mold needs to be lifted or lowered as a whole, the telescopic electromagnetic pin 4 is started and engages with the driving wheel A271 and the driving wheel B281 respectively, driving different groups of driven wheels A272 and driven wheels B282 to accelerate or decelerate in the opposite direction, thereby compensating for the pitch and thread direction, so that all the lifting mechanisms 2 are synchronously unfolded or retracted, driving the blade mold to be lifted or lowered as a whole.
