Description

Technical Field

[0001] The present invention relates to the technical field of wind blade grinding, and particularly relates to an automatic grinding device for a wind turbine blade. Background Art

[0002] The wind turbine blade is one of the core components of a wind turbine. The wind turbine blade has high requirements for materials. It not only needs to have a light weight, but also needs to have high strength, corrosion resistance, and fatigue resistance. Therefore, current wind turbine manufacturers widely use composite materials to manufacture wind turbine blades. The proportion of composite materials in the entire wind turbine blade is even as high as 90%. The blade manufacturing materials have evolved from the initial linen cloth covering a wooden board to steel, aluminum alloy, and until the current composite materials. The blade shell often uses glass fiber reinforced resin, and the blade tip and the main blade beam use carbon fiber with higher strength. The leading edge, trailing edge, and shear web parts often use sandwich structure composite materials. However, during the grinding process, the grinding position is prone to overheating and debris accumulation, which makes the debris easily cause damage to the blade at the grinding position, thereby increasing the error of the blade during grinding by the device and reducing the precision of blade grinding.

[0003] In summary, during the grinding process, the grinding position is prone to overheating and debris accumulation, which makes the debris easily cause damage to the blade at the grinding position, thereby increasing the error of the blade during grinding by the device and reducing the precision of blade grinding. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: An automatic grinding device for a wind turbine blade of the present invention includes a processing box. The processing box body is provided with an alarm, and a flipping box door is arranged at the top of the front of the processing box. Both sides of the bottom of the flipping box door are rotatably connected with stretching rods. The ends of the stretching rods away from the flipping box door are rotatably connected to the processing box. Two purifiers are fixedly connected to the outer walls on both sides of the processing box. The stretching rods can support the flipping box door as it moves on the processing box, thereby increasing the stability of the flipping box door during flipping and preventing the flipping box door from falling when the flipping stops. And two purifiers are arranged on the processing box, which is convenient for using the purifiers to remove the peculiar smell inside the processing box, thereby avoiding the occurrence of peculiar smell inside the processing box during the grinding process. Frame, the frame has support columns, and a grinding frame arranged at the top of the frame. On both sides of the bottom of the front of the grinding frame, detection light curtains are fixedly connected. The bottom of the detection light curtain is fixedly connected to the frame. The bottom of the outer walls on both sides of the grinding frame is fixedly connected to a processing box. By placing the detection light curtains opposite to each other on the frame, a detection area can be generated after the detection light curtains are placed opposite to each other. Thus, when a worker reaches into the interior of the processing box through the detection area during the grinding process, the grinding process of the equipment stops, thereby avoiding the situation of damaging the worker during grinding. Along with the cooperation of the processing box and the flipping box door to limit the flying debris during grinding, the grinding frame includes: Energy box, the energy box has a storage battery, and a balance bracket arranged at the bottom of the energy box. At the middle position of the bottom of the balance bracket, a grinding disc is fixedly connected. At a position of the balance bracket close to the grinding disc, a spraying pipe is fixedly connected. Both ends of the spraying pipe extend to the outside of the balance bracket; Processing table, the processing table has a screening plate, and a collection box arranged at the bottom of the processing table. The bottom of the collection box is fixedly connected to the frame. The bottom of the collection box extends to the inside of the frame. At a position on the inner cavity bottom of the processing table adapted to the grinding disc, a partition seat is fixedly connected. By using the spraying pipe to cool the position where the grinding disc grinds with the water flow inside the collection box, and at the same time, the flow of the water flow on the fan blades can wash away the debris, thereby ensuring the cleanliness of the grinding position of the fan blades and preventing the situation that the debris accumulates at the grinding position of the fan blades and scratches the fan blades, further improving the integrity during the grinding process of the fan blades. The screening plate of the processing table can filter the water flow and facilitate the circulation of the water flow, preventing the situation that the water flow accumulates on the processing table, thereby ensuring the accuracy of the equipment for grinding the fan blades. The processing table can block some debris with low splash. The bottom of both sides of the balance bracket is fixedly connected to the processing table. One end of the spraying pipe far from the balance bracket is communicated with the collection box. The middle position at the top of the collection box penetrates through the processing table and extends to the inside of the processing table. The bottom position of the partition seat penetrates through the processing table and extends to the inside of the processing table.

[0005] Preferably, the balance bracket includes a displacement block, and adjusting force arms are uniformly and slidably connected to the outer walls on both sides of the displacement block. A lifting driver is fixedly connected to the bottom of the displacement block, and the top end of the lifting driver is slidably connected to the adjusting force arms on both sides of the displacement block. The power received by the displacement block on the adjusting force arms can drive the lifting driver to move in the horizontal direction, facilitating the adjustment of the position where the lifting driver drives the grinding disc to grind. And the displacement block is inside the adjusting force arms, which can support the lifting driver, thereby increasing the contact area of the lifting driver. Moreover, the lifting driver provides power for the rotation of the grinding disc, enabling the grinding disc to grind the wind blade when rotating, thus ensuring the grinding strength of the grinding disc on the wind blade. A support member is rotatably connected to the middle of the outer surface of the lifting driver, and a mounting pipe rack is fixedly connected to the bottom of the support member close to the lifting driver. By connecting the mounting pipe rack with the support member, the mounting pipe rack can fix the spraying pipe, and the mounting pipe rack is kept horizontal with the fixation of the support member, thereby avoiding the situation of offset when the mounting pipe rack connects the spraying pipe to convey water flow.

[0006] Preferably, the partition seat includes a load-bearing arm, and a limit disc is fixedly connected to the middle position of the top of the load-bearing arm. A mounting frame is fixedly connected to the top of the limit disc. By connecting the load-bearing arm with the limit disc, the load-bearing arm can support the limit disc, facilitating the fixation of the limit disc when the load-bearing arm is in a horizontal state, thereby increasing the stability of the mounting position of the limit disc. At the same time, the load-bearing arm can play a role in partitioning on the processing table, enabling it to partition the space on the processing table, facilitating the limit disc and the mounting frame to have an activity space for component installation. A turntable is rotatably connected to the middle position of the top of the mounting frame, and clamping frames are rotatably connected to both sides of the bottom of the turntable. The bottom of the clamping frame is fixedly connected to the mounting frame. By driving the turntable to rotate by a motor on the mounting frame, the turntable can adjust the position of the placed wind blade during rotation. And the turntable contacts the clamping frame, enabling the clamping frame to reinforce the turntable on the mounting frame, thereby avoiding the situation of tilting during the rotation of the turntable. The groove on the turntable can drain the water flow and debris on its surface, further accelerating the dropping of the debris.

[0007] Preferably, the collection box includes a box body. The left side of the inner cavity bottom of the box body is fixedly connected with a conveying box. The bottom of the right outer wall of the conveying box is communicated with an inner circulation pipe. The outer surface of the inner circulation pipe is fixedly connected with the box body. By connecting the inner circulation pipe with the conveying box, the water pump inside the conveying box conveys water flow to the inside of the spraying pipe through the inner circulation pipe, which is convenient for ensuring that the spraying pipe continuously sprays the leakage, avoiding the sudden interruption of the water flow during the spraying process of the spraying pipe, and further improving the overall processing efficiency of the equipment. The middle parts of the two inner side walls of the box body are slidably connected with a screening rack. The top of the right outer wall of the box body is communicated with a water injection pipe. The left end of the water injection pipe penetrates through the box body. By placing activated carbon inside the box body, it is convenient for the activated carbon to purify with the water flow inside the box body, so that the water flow is not likely to produce peculiar smell during the placement process. The water injection pipe on the box body can add water flow from the outside, and a water outlet pipe is arranged at a position opposite to the water injection pipe, which can discharge the water flow inside the box body after long-term use of the water flow, and can discharge the debris collected inside the box body together during the process of discharging the water flow, thereby improving the cleanliness inside the box body and further using the water flow to achieve the effect of cooling.

[0008] Preferably, the adjusting force arm includes a screw rod. The left end of the screw rod is rotatably connected with a bearing frame. The middle position of the top of the bearing frame is slidably connected with an increasing contact frame. By rotatably connecting the screw rod with a displacement block, the screw rod drives the displacement block to move as the displacement motor rotates, and the displacement block drives the increasing contact frame to move when moving, which is convenient for protecting the displacement block when the increasing contact frame moves, thereby increasing the bearing capacity of the displacement block and avoiding the situation of slipping or shaking during the movement of the displacement block. At the same time, the sliding of the increasing contact frame on the bearing frame can limit the movement of the displacement block. The two outer side walls of the bearing frame are fixedly connected with assembly plates. The bottom of the assembly plates is fixedly connected with fixing plates. The fixing plates are fixedly connected with the bearing frame near the assembly plates. By connecting the fixing plates with the assembly plates, the fixing plates fix the height between the bearing frame and the processing table, thereby avoiding the situation that the bearing frame tilts on the fixing plates, resulting in the grinding disc not being able to fully contact the wind blade during subsequent grinding, and the reinforcement of the bearing frame by the fixing plates and the assembly plates can ensure that the bearing frame is in a balanced state.

[0009] Preferably, the clamping frame includes a guiding plate, a moving frame is slidably connected to the top of the guiding plate, the bottom of the moving frame penetrates through the guiding plate and extends into the interior of the guiding plate, a fine-tuning block is fixedly connected to the top of the guiding plate, and an elastic arc plate is slidably connected to the top of the side of the fine-tuning block close to the moving frame. When the elastic arc plate contacts the wind blade on the fine-tuning block, the elastic arc plate is gradually pressured by the wind blade and moves into the interior of the fine-tuning block, facilitating the adjustment of the clamping range of the elastic arc plate on the wind blade, thereby increasing the strength of the waste liquid height. Moreover, the contact surface of the elastic arc plate has elasticity, avoiding damage or breakage when the elastic arc plate contacts the wind blade, further improving the integrity of the wind blade itself. It is possible to clean the debris at the installation position of the wind blade by using water flow. A hydraulic rod is fixedly connected to the bottom of the side of the moving frame close to the elastic arc plate. The moving frame moves on the guiding plate driven by the hydraulic rod, so that the movement of the moving frame adjusts the position of the fine-tuning block thereon, and when the moving frame moves, it can clean the debris falling on the guiding plate, avoiding the situation that the movement of the moving frame is stuck due to debris adhering to the guiding plate.

[0010] Preferably, the screening frame includes a reinforcing plate, stabilizing plates are fixedly connected to both sides of the bottom of the reinforcing plate, a rotary roller frame is fixedly connected to the middle position of the bottom of the stabilizing plates, and a diversion arc plate is rotatably connected to the outer surface of the rotary roller frame. When the diversion arc plate is pressured by the filtered water flow on the rotary roller frame, it can tilt, thereby increasing the space for the water flow to drop on the diversion arc plate. Moreover, the rotary roller frame is installed on the stabilizing plates, making the stabilizing plates have good stability in the box body, avoiding the problem of the stabilizing plates sliding down from the box body. The position of the diversion arc plate close to the rotary roller frame is rotatably connected to the stabilizing plates. Filter mesh plates are rotatably connected to the outer walls on both sides of the reinforcing plate. When the filter mesh plates are pressured by the water flow dropping on the stabilizing plates, they gradually tilt, generating a movable space between them and the box body while filtering the water flow, facilitating the subsequent collection of water flow with less debris residue, thereby avoiding the situation that debris circulates with the water flow during subsequent water flow use, further reducing the blockage of the inner circulation pipe during use. Moreover, the filter mesh plates can automatically return to the initial position when the pressure is lost, thereby ensuring the filtering effect during re-use.

[0011] The present invention provides an automatic grinding device for a fan blade. It has the following beneficial effects: 1. The automatic grinding device for the fan blades is provided with a detection light curtain, a frame, a spraying pipe, and a processing table. The detection light curtains are placed opposite to each other on the frame in pairs, so that a detection area can be generated after the detection light curtains are placed opposite to each other. Thus, when the staff reaches into the interior of the processing box through the detection area during the grinding process, the grinding process of the equipment stops. The spraying pipe uses the water flow inside the collection box to cool the position where the grinding disc grinds. At the same time, the flow of water on the fan blades can wash away the debris, thereby ensuring the cleanliness of the grinding position of the fan blades. The screening plate of the processing table can filter the water flow and facilitate the flow of water, preventing the water flow from gathering on the processing table, and further ensuring the accuracy of the equipment for grinding the fan blades. The processing table can block some debris with low splash.

[0012] 2. The automatic grinding device for the fan blades, when the filter screen plate is under the pressure of the water flow dropping on the stabilizing plate, gradually tilts, so that while filtering the water flow, a moving space is generated between it and the box body, facilitating that there is no easy residue of debris in the subsequently collected water flow. And when the filter screen plate loses pressure, it can automatically return to the initial position, thus ensuring the filtering effect when used again. The guiding arc plate can tilt when under the pressure of the filtered water flow on the rotary roller frame, thereby increasing the space for the water flow to drop on the guiding arc plate.

[0013] 3. The automatic grinding device for the fan blades, when the elastic arc plate contacts the fan blade on the fine-tuning block, the elastic arc plate is gradually pressured by the fan blade and moves into the interior of the fine-tuning block, facilitating the adjustment of the clamping range of the elastic arc plate for the fan blade, thereby increasing the intensity of the waste liquid height. It can use the water flow to clean the debris at the installation position of the fan blade. The moving frame moves on the guiding plate driven by the hydraulic rod, so that the movement of the moving frame adjusts the position of the fine-tuning block on it.

[0014] 4. The automatic grinding device for the fan blades, the screw is rotationally connected to the same displacement block, so that the screw drives the displacement block to move as the displacement motor rotates, avoiding the situation of slipping or shaking during the movement of the displacement block. At the same time, the sliding of the additional contact frame on the bearing frame can limit the movement of the displacement block. The fixed plate is connected to the assembly plate, so that the fixed plate fixes the height between the bearing frame and the processing table, thereby preventing the bearing frame from tilting on the fixed plate.

[0015] 5. The automatic grinding device for the fan blades, activated carbon is placed inside the box body, facilitating the purification of the activated carbon with the water flow inside the box body, so that the water flow is not likely to generate peculiar smell during the placement process, thereby improving the cleanliness inside the box body. Further, the water flow is used to achieve the cooling effect. The internal circulation pipe is connected to the delivery box, so that the water pump inside the delivery box transports the water flow to the inside of the spraying pipe through the internal circulation pipe, facilitating ensuring the continuous spraying of the spraying pipe for leakage, and further improving the overall processing efficiency of the equipment.

[0016] 6. The automatic grinding device for the fan blades is connected to the limit disc through the load-bearing arm, enabling the load-bearing arm to support the limit disc, facilitating the fixation of the limit disc when the load-bearing arm is in a horizontal state, thereby increasing the stability of the installation position of the limit disc. The turntable rotates driven by the motor on the mounting frame, enabling the turntable to adjust the position of the placed fan blades during rotation, thereby avoiding the situation of tilting during the rotation of the turntable and further accelerating the fall of debris.

[0017] 7. The automatic grinding device for the fan blades can drive the lifting actuator to move horizontally by the displacement block receiving power on the adjusting force arm, facilitating the adjustment of the position where the lifting actuator drives the grinding disc to grind. And the displacement block inside the adjusting force arm can support the lifting actuator, thereby increasing the contact area of the lifting actuator. The installation pipe rack is connected to the support member, enabling the installation pipe rack to fix the spraying pipe, thereby avoiding the situation of deviation when the installation pipe rack connects the spraying pipe to convey water.

And the displacement block 524 is inside the adjusting force arms 525, which can support the lifting driver 523, thereby increasing the contact area of the lifting driver 523. Moreover, the lifting driver 523 provides power for the rotation of the grinding disc 54, enabling the grinding disc 54 to grind the wind blades during rotation, thus ensuring the grinding intensity of the grinding disc 54 on the wind blades.

And the turntable 554 contacts the clamping brackets 555, enabling the clamping brackets 555 to reinforce the turntable 554 on the installation rack 553, thereby avoiding the situation of the turntable 554 tilting during rotation. The groove on the turntable 554 can drain the water flow and debris on its surface, further accelerating the falling of the debris.

[0025] Among them, the collection box 56 includes a box body 561. On the left side of the inner cavity bottom of the box body 561, a conveying box 562 is fixedly connected. At the bottom of the right outer wall of the conveying box 562, an inner circulation pipe 563 is communicated.

Through the connection between the screw rod 74 and a displacement block 524, the screw rod 74 drives the displacement block 524 to move along with the rotation of the displacement motor. When the displacement block 524 moves, it drives the contact increasing frame 73 to move, which is convenient for protecting the displacement block 524 when the contact increasing frame 73 moves, thereby increasing the bearing capacity of the displacement block 524 and avoiding the situation of slipping or shaking of the displacement block 524 during the moving process. At the same time, the sliding of the contact increasing frame 73 on the bearing frame 72 can limit the movement of the displacement block 524. On the two outer walls of the bearing frame 72, assembly plates 71 are fixedly connected. At the bottom of the assembly plates 71, fixing plates 75 are fixedly connected. The fixing plates 75 are fixedly connected to the bearing frame 72 at positions close to the assembly plates 71. Through the connection between the fixing plates 75 and the assembly plates 71, the fixing plates 75 fix the height between the bearing frame 72 and the processing table 57, thereby avoiding the inclination of the bearing frame 72 on the fixing plates 75, resulting in the situation that the grinding disc 54 cannot fully contact the fan blade during subsequent grinding, and the reinforcement of the bearing frame 72 by the fixing plates 75 and the assembly plates 71 can ensure that the bearing frame 72 is in a balanced state.

Moreover, the contact surface of the elastic arc plate 83 has elasticity, avoiding damage or breakage when the elastic arc plate 83 contacts the wind blade, further improving the integrity of the wind blade itself. It can utilize the water flow to clean the debris at the installation position of the wind blade. A hydraulic rod 81 is fixedly connected to the bottom of the side of the moving frame 84 close to the elastic arc plate 83. The moving frame 84 moves on the guiding plate 82 driven by the hydraulic rod 81, enabling the movement of the moving frame 84 to adjust the position of the fine-tuning block 85 thereon. And when the moving frame 84 moves, it can clean the debris falling on the guiding plate 82, avoiding the situation where the movement of the moving frame 84 is stuck due to the adhesion of the debris to the guiding plate 82.

[0028] During use, the flipping box door 3 is flipped and opened on the processing box 1, then the stretching rod 4 supports it on the processing box 1. Then the wind blade is placed on the turntable 554 on the processing table 57. At this time, the hydraulic rod 81 on the mounting frame 553 stretches and the moving frame 84 moves on the guiding plate 82, causing the moving frame 84 to drive the fine-tuning block 85 and the elastic arc plate 83 thereon to approach the wind blade when it moves. And when the elastic arc plate 83 contacts the wind blade on the turntable 554 during its movement, it moves slightly into the interior of the fine-tuning block 85 under the pressure of the wind blade. Moreover, the motor on the mounting frame 553 drives the turntable 554 to rotate on the limit disk 552. The detection light curtain 6 is powered on on the machine frame 7 to form a detection area, and the flipping box door 3 and the processing box 1 are closed. The fixed plate 75 and the assembly plate 71 support the bearing frame 72 to maintain balance. And the screw rod 74 rotates driven by the displacement motor, causing the rotation of the screw rod 74 to drive the displacement block 524 to move horizontally on the bearing frame 72. At the same time, the displacement block 524 drives the touch-increasing frame 73 and the lifting driver 523 to move. The lifting driver 523 drives the grinding disk 54 to rotate while adjusting the height at which the grinding disk 54 contacts the wind blade. The spraying pipe 53 sprays water flow at the position where the grinding disk 54 is polished on the support member 522 through the installation pipe rack 521. The water injection pipe 565 on the box body 561 adds water flow to its interior. And the water pump in the conveying box 562 in the box body 561 transports the water flow to the interior of the spraying pipe 53 through the inner circulation pipe 563, so that the debris washed by the water flow enters the interior of the box body 561 through the screening plate on the processing table 57.

[0029] Example 2

[0030] Please refer to Figure 8 Based on Example 1, the present invention provides a technical solution: The screening rack 564 includes a reinforcement plate 92. Both sides of the bottom of the reinforcement plate 92 are fixedly connected with stabilizing plates 94. The middle position of the bottom of the stabilizing plate 94 is fixedly connected with a rotary roller frame 95. The outer surface of the rotary roller frame 95 is rotatably connected with a diversion arc plate 93. When the diversion arc plate 93 is subjected to the pressure of the filtered water flow on the rotary roller frame 95, it can be inclined, thereby increasing the space for the water flow to fall on the diversion arc plate 93. Moreover, the rotary roller frame 95 is installed on the stabilizing plate 94, making the stabilizing plate 94 have good stability in the box body 561, avoiding the problem that the stabilizing plate 94 slides down from the box body 561. The position of the diversion arc plate 93 close to the rotary roller frame 95 is rotatably connected with the stabilizing plate 94. Both outer walls of the reinforcement plate 92 are rotatably connected with a filter mesh plate 91. When the filter mesh plate 91 is subjected to the pressure of the water flow falling on the stabilizing plate 94, it gradually inclines, generating a movable space between it and the box body 561 while filtering the water flow, facilitating the subsequent collection of water flow without leaving debris easily, thereby avoiding the situation where debris circulates with the water flow during subsequent water flow use, further reducing the blockage of the inner circulation pipe 563 during use. And the filter mesh plate 91 can automatically return to the initial position when the pressure is lost, thus ensuring the filtering effect during re - use.

[0031] During use, when the water flow drops into the interior of the box body 561 after flowing through the processing table 57, the reinforcement plate 92 on the stabilizing plate 94 contacts the processing table 57, and the filter mesh plate 91 inclines when it is subjected to the pressure of the water flow on the stabilizing plate 94. At this time, a movable space appears between the filter mesh plate 91 and the box body 561. When the filtered water flow impacts the diversion arc plate 93, the diversion arc plate 93 swings on the rotary roller frame 95, and as the pressure on the filter mesh plate 91 and the diversion arc plate 93 themselves disappears, they can return to the initial position to prepare for the next time.

[0032] Example 3

[0033] Please refer to Figures 1-8 Based on Example 1 and Example 2, the present invention provides a technical solution: A method for using an automatic grinding device for a fan blade. Step 1: After flipping the flip - top box door 3 on the processing box 1, use the stretching rod 4 to support it. Place the blade on the turntable 554. The telescopic movement of the hydraulic rod 81 drives the fine - tuning block 85 to slide on the guiding plate 82 through the moving frame 84, so that the elastic arc plate 83 on the fine - tuning block 85 gradually approaches the blade and fixes it. Step 2: When the elastic arc plate 83 moves onto the turntable 554, the turntable 554 is driven by the motor on the mounting frame 553 to rotate, and the hydraulic rod 81 is placed along with the moving space generated between the mounting frame 553 and the turntable 554. The mounting frame 553 is placed on the load-bearing arm 551 via the limit disc 552; Step 3: After the wind blades are fixed, the box door 3 is flipped and closed with the processing box 1 again. The detection light curtain 6 is powered on and operates on the machine frame 7. Along with the water pump inside the conveying box 562, the water flow inside the box body 561 is transported through the internal circulation pipe 563 into the inside of the spraying pipe 53, so that the spraying pipe 53 flushes the grinding disc 54 on the installation pipe rack 521; Step 4: The screw rod 74 rotates driven by the displacement motor, and the rotating screw rod 74 drives the displacement block 524 to move on the bearing frame 72. When the displacement block 524 moves, it drives the contact-increasing frame 73 and the lifting driver 523 to move, so that the lifting driver 523 drives the grinding disc 54 to rotate and grind the wind blades; Step 5: The water flow sprayed by the spraying pipe 53 flows from the turntable 554 onto the processing table 57, and it enters the inside of the box body 561 through the screening plate on the processing table 57. The processing table 57 supports the bearing frame 72 via the fixing plate 75 and the assembly plate 71; Step 6: The water flow enters the inside of the box body 561 and contacts the filter screen plate 91 on the stabilizing plate 94, so that the impact force of the falling water flow makes the filter screen plate 91 tilt. When the water flow leaves the filter screen plate 91, it drops onto the guiding arc plate 93, causing the guiding arc plate 93 to swing on the rotary roller frame 95 under the pressure of the water flow, creating space for the falling water flow.
