Description

Technical Field

[0001] This disclosure relates to the technical field of auxiliary equipment for blade production, and particularly to an auxiliary material removal device and a moving device. Background Technology

[0002] In the field of wind turbine blade manufacturing, after the blade is cast, auxiliary materials such as vacuum film, guide net, and flow channel adhering to its surface need to be removed. Currently, this step mostly relies on manual removal. However, there is a large adhesive force between the auxiliary materials and the blade, which means that multiple workers are needed and a lot of force is required to tear them off, which is time-consuming and labor-intensive, and consumes a lot of manpower and time costs. Utility Model Content

[0003] The purpose of this disclosure is to provide an auxiliary material removal device and a moving device that can automatically remove auxiliary materials, thereby improving production efficiency and reducing production costs.

[0004] According to one aspect of this disclosure, an auxiliary material removal device is provided, the auxiliary material removal device having a forward direction, the auxiliary material removal device comprising:

[0005] The movable body has a peeling part at its front end along the forward direction, and the top surface of the peeling part is inclined downward along the forward direction;

[0006] A traction assembly is disposed on the mobile body. The traction assembly includes a first rotating member and a second rotating member arranged vertically. The first rotating member and the second rotating member clamp the sheet-like auxiliary material and rotate it to drive the auxiliary material removal device to move along the forward direction.

[0007] The technical solution provided in this disclosure employs a structure that uses two rotating wheels to clamp sheet-like auxiliary materials. The sheet-like auxiliary materials are held between the two wheels, and the rotation of the rotating wheels directly applies traction force to the sheet-like auxiliary materials, driving the entire auxiliary material removal device forward. This method completely eliminates the reliance on friction from the inner wall of the blade half-shell, making it particularly suitable for situations where the inner wall of the wind turbine blade half-shell has a certain curvature and the auxiliary material removal device is lightweight, resulting in low contact friction with the inner wall of the blade half-shell. This achieves stable and controllable autonomous movement. Simultaneously, the two rotating wheels clamping and rotating the sheet-like auxiliary materials also provide traction and pulling, effectively peeling them off. Furthermore, it also provides tension to the sheet-like auxiliary materials, working in conjunction with the peeling section as the moving body moves to lift and peel the sheet-like auxiliary materials from the product. No additional tensioning structure is required, reducing costs and minimizing manual intervention, achieving automated removal of auxiliary materials, improving production efficiency, and lowering production costs.

[0008] Optionally, the traction assembly has two components, which are respectively disposed adjacent to opposite sides of the mobile body.

[0009] The above scheme ensures that the traction components have sufficient traction force on both the auxiliary material removal equipment and the sheet-like auxiliary materials, meeting the requirements for material stripping. Simultaneously, the two traction components are positioned adjacent to opposite sides of the moving body, ensuring a more balanced force on both sides of the auxiliary material removal equipment and guaranteeing its smooth movement.

[0010] Optionally, the auxiliary material removal device further includes a cutting blade, which is positioned above the mobile body and between the two traction components.

[0011] With the above scheme, when the traction component pulls the sheet-like auxiliary material backward relative to the moving body, the sheet-like auxiliary material is first cut into two pieces by the cutting blade. Each piece is then pulled backward by a traction component, thereby dividing a whole sheet-like auxiliary material into two pieces, reducing the weight of a single piece of auxiliary material and facilitating subsequent cleaning operations.

[0012] Optionally, a support portion is provided above the movable body, and the cutting blade is located at the front end of the support portion along the forward direction; the first rotating member is located above the second rotating member, and the first rotating member is connected to the support portion.

[0013] By providing a support above the mobile body and connecting the first rotating component to the support, the structure can be simplified, production costs reduced, and the structure of the auxiliary material removal equipment can be made simpler, improving the overall aesthetics.

[0014] Optionally, the side of the mobile body is provided with a peeling component, the peeling component includes a peeling block, the peeling block is provided with peeling holes, and the peeling holes penetrate through the opposite ends of the peeling block along the forward direction.

[0015] Through the above scheme, not only sheet-like auxiliary materials can be peeled off and removed during a single movement of the mobile body, but also tubular auxiliary materials can be peeled off and removed, further improving the production efficiency of the blade shell.

[0016] Optionally, the peeling assembly further includes a separating blade disposed adjacent to the inlet edge of the peeling hole; there are two separating blades, which are respectively located on the side of the peeling hole adjacent to the moving body and on the side of the peeling hole away from the moving body.

[0017] The above method can be used to remove other components adhering to the tubular auxiliary material by using a separating blade, avoiding the tubular auxiliary material from getting stuck at the peeling hole, improving the smoothness of peeling, and ensuring the stable operation of the equipment.

[0018] Optionally, there are two peeling components, which are located on opposite sides of the mobile body.

[0019] The above method allows for the simultaneous stripping of two tubular auxiliary materials using two stripping components, thereby improving stripping efficiency.

[0020] Optionally, the auxiliary material removal device further includes a cutting assembly located at the rear end of the peeling block along the forward direction, the cutting assembly being adapted to cut the tubular auxiliary material extending from the peeling hole in a direction perpendicular to the forward direction.

[0021] The above method involves using a cutting component to cut the tubular auxiliary material extending from the peeling hole, thereby cutting the tubular auxiliary material into multiple segments to facilitate subsequent cleaning and transportation.

[0022] Optionally, both the first rotating member and the second rotating member are driving wheels; or, one of the first rotating member and the second rotating member is a driving wheel, and the other is a pressure wheel.

[0023] Optionally, the bottom surface of the peeling portion is inclined upward along the forward direction.

[0024] The above method allows the front end of the mobile unit to be raised, making it easier to overcome obstacles of a certain height and improving obstacle-crossing ability.

[0025] According to another aspect of this disclosure, a mobile device is also provided, the mobile device comprising:

[0026] The movable body is used to move on the inner wall surface of the blade half-shell;

[0027] A traction assembly is disposed on the mobile body. The traction assembly includes a first rotating member and a second rotating member arranged vertically. The first rotating member and the second rotating member clamp the traction member and rotate to drive the mobile device to move in the forward direction. Attached Figure Description

[0040] In the production of wind turbine blades, the blade is typically divided into two parts: a pressure-side semi-shell and a suction-side semi-shell. These two semi-shells are cast separately and then joined together to form a whole. Before casting each semi-shell, core material, a guide net, and injection channels need to be laid on the mold. After casting, these auxiliary materials are peeled off from the semi-shell. Currently, the peeling of the guide net and injection channels relies heavily on manual removal. However, both the guide net and injection channels have significant adhesion to the blade semi-shell, requiring multiple workers and considerable force to remove them, resulting in a time-consuming and labor-intensive process with substantial manpower and time costs.

[0041] To address this, this disclosure attempted to use a moving device to drive the stripping device, thereby automatically stripping and removing the auxiliary materials. However, on the one hand, due to the considerable flexibility of the guide net, a tensioning structure is required to keep the guide net taut before the stripping operation can be performed, increasing the overall equipment cost. On the other hand, because the overall equipment is relatively lightweight, the friction between the moving device and the inner wall of the blade half-shell is small, which cannot meet the forward traction force required for stripping. Furthermore, the inner wall of the blade half-shell has a certain degree of curvature, making it impossible to increase the traction force by increasing the contact area between the moving wheels of the moving device and the blade half-shell. As a result, the overall equipment frequently slips, making it impossible to complete the normal stripping and removal operation.

[0042] Based on this, this disclosure further modifies the driving method of the mobile device by installing two rotating wheels on top of the mobile device. These two rotating wheels clamp the guide net and rotate to generate a traction force that drives the mobile device forward, thus meeting the mobile device's movement requirements. Simultaneously, the two rotating wheels clamping and rotating the guide net also tension the net, facilitating the peeling operation without requiring an additional tensioning structure, thereby reducing costs.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this disclosure, but not all embodiments.

[0044] This disclosure provides an auxiliary material removal device, which is at least used for self-moving separation and removal of auxiliary materials from the product, simplifying labor costs and improving production efficiency, thereby optimizing the production operation of blades. Specifically, as... Figure 1 and Figure 2 As shown, the auxiliary material removal device has a forward direction and moves along this direction. The auxiliary material removal device includes a moving body 100, which serves as the main supporting component, primarily supporting and / or protecting other components. The moving body 100 has a peeling section 110 at its front end along the forward direction. The top surface of the peeling section 110 is inclined downwards along the forward direction, thus forming a pointed structure. In this way, as the moving body 100 moves, the peeling section 110 can not only use its top surface to lift and peel the sheet-like auxiliary material 10 attached to the product (e.g., a wind turbine blade shell) from the product, but also use its top surface to distribute stress, reducing stress concentration between the sheet-like auxiliary material 10 and the moving body 100, facilitating the movement of the sheet-like auxiliary material 10 in the opposite direction to the forward direction.

[0045] The auxiliary material removal device also includes a traction assembly 200, which is mounted on the mobile body 100. The traction assembly 200 includes a first rotating member 210 and a second rotating member 220 arranged vertically. The first rotating member 210 and the second rotating member 220 clamp the sheet-like auxiliary material 10. The clamping contact area of ​​the first rotating member 210 and the second rotating member 220 is located above the mobile body 100. The first rotating member 210 and the second rotating member 220 pull the sheet-like auxiliary material 10 in the direction of rotation by rotating, and simultaneously, the reaction force drives the auxiliary material removal device to move in the forward direction. Thus, by using a structure where two rotating wheels clamp the sheet-like auxiliary material 10, the sheet-like auxiliary material 10 is held between the two wheels, and the rotation of the rotating wheels directly applies traction force to the sheet-like auxiliary material 10, driving the entire auxiliary material removal device forward. This method completely eliminates the reliance on the friction force of the inner wall of the blade half-shell, and is especially suitable for situations where the inner wall of the wind turbine blade half-shell has a certain curvature and the auxiliary material removal equipment is relatively light, resulting in low contact friction with the inner wall of the blade half-shell, thus achieving stable and controllable autonomous movement.

[0046] Simultaneously, the two rotating wheels clamp and rotate the sheet-like auxiliary material 10, which can also pull and tug on the sheet-like auxiliary material 10 to peel it off. Furthermore, it can also tension the sheet-like auxiliary material 10, and together with the peeling part 110 moving with the moving body 100, it lifts and peels the sheet-like auxiliary material 10 from the product. No additional tensioning structure is needed, reducing costs, and automatic removal of auxiliary materials can be achieved, optimizing blade production operations.

[0047] For example, both the first rotating member 210 and the second rotating member 220 can be circular wheel structures. To increase the friction between the first rotating member 210 and the second rotating member 220, flexible sleeves such as rubber sleeves can also be fitted onto the first rotating member 210 and the second rotating member 220. Of course, the first rotating member 210 and the second rotating member 220 can also be gears or tracked rotating members with an elliptical cross-section.

[0048] Furthermore, the bottom surface of the peeling section 110 is inclined upward along the forward direction, thereby causing the front end of the moving body 100 to be raised, which can facilitate the crossing of obstacles of a certain height and improve the obstacle crossing ability.

[0049] In some embodiments, the bottom of the movable body 100 may be provided with a movable wheel 101, and the movable body 100 is supported on the product by the movable wheel 101. The movable wheel 101 can be used as a driven wheel. When the first rotating member 210 and the second rotating member 220 drive the auxiliary material removal device to move in the forward direction by rotation, the movable wheel 101 rotates along with the movement of the auxiliary material removal device.

[0050] In some other embodiments, the movable wheel 101 can also be used as the driving wheel. That is, the movable body 100 has a motor that drives the movable wheel 101 to rotate, so that the movable body 100 moves actively. Thus, the auxiliary material removal device is driven to move in the forward direction by the traction component 200 and the movable wheel 101.

[0051] The aforementioned traction component 200 may be a single unit, and the traction component 200 may be located directly above or on any side of the mobile body 100.

[0052] The aforementioned traction assembly 200 may also have two components, with each traction assembly 200 positioned adjacent to opposite sides of the moving body 100. This ensures that the traction assembly 200 provides sufficient traction force to both the auxiliary material removal device and the sheet-like auxiliary material 10, meeting the requirements for auxiliary material peeling. Simultaneously, the placement of the two traction assemblies adjacent to opposite sides of the moving body 100 allows for a more balanced force distribution on both sides of the auxiliary material removal device, ensuring smooth movement of the device.

[0053] In some embodiments, the auxiliary material removal device further includes a cutting blade 300, which is located above the movable body 100 and between the two traction components 200, with the cutting blade 300 positioned in front of the traction components 200 in the forward direction. Thus, when the traction components 200 pull the sheet-like auxiliary material 10 backward relative to the movable body 100, the sheet-like auxiliary material 10 is first cut into two pieces by the cutting blade 300, and each piece is then pulled backward by a separate traction component 200, thereby dividing a single sheet-like auxiliary material 10 into two pieces, reducing the weight of a single piece and facilitating subsequent cleaning operations.

[0054] In this embodiment, the side of the mobile body 100 may be provided with a connecting rod to connect the upper rotating parts of the two traction components 200, and the lower rotating parts of the traction components 200 are directly connected to the mobile body 100.

[0055] Alternatively, a support portion 120 can be provided above the mobile body 100, connecting the upper rotating parts of the two traction components 200. Specifically, the cutting blade 300 is located at the front end of the support portion 120 along the forward direction, the first rotating part 210 is located above the second rotating part 220, the first rotating part 210 is connected to the support portion 120, and the second rotating part 220 is connected to the side of the mobile body 100, thereby simplifying the structure, reducing production costs, and making the structure of the auxiliary material removal equipment more concise and improving the overall aesthetics. For example, the width of the cutting blade 300 can gradually expand in the opposite direction to the forward direction, so that the two sides of the cutting blade 300 smoothly engage with the two sides of the support portion 120, avoiding the pulling and jamming of the sheet-like auxiliary material 10 after cutting, and ensuring the smooth traction of the sheet-like auxiliary material 10.

[0056] The auxiliary material removal equipment can not only peel off and remove sheet-like auxiliary materials 10, but also remove tubular auxiliary materials 20. For details, please refer again. Figure 1 and Figure 2 As shown, in some embodiments, the side of the movable body 100 is provided with a peeling component 400. The peeling component 400 includes a peeling block 410, which has peeling holes 411 that extend through opposite ends of the peeling block 410 in the forward direction. This allows one end of the tubular auxiliary material 20 to be inserted into the peeling hole 411 first, and then the tubular auxiliary material 20 adhering to the product to be peeled off as the movable body 100 moves. Exemplarily, the peeling component 400 may be located in front of, behind, or directly below the traction component 200 in the forward direction.

[0057] Furthermore, there may be two peeling components 400, which are located on both sides of the movable body 100 respectively. In this way, two peeling components 400 can be used to peel two tubular auxiliary materials 20 at the same time, thereby improving the peeling efficiency.

[0058] In practical applications, other components adhering to the tubular auxiliary material 20 can be removed using the inlet edge of the peeling hole 411, allowing the tubular auxiliary material 20 to smoothly enter the peeling hole 411. Alternatively, a separating blade 420 can be provided at the inlet edge of the peeling hole 411 to remove other components adhering to the tubular auxiliary material 20. For example, the separating blade 420 can be arranged in a ring around the inlet of the peeling hole 411. Or, as... Figure 2 As shown, there may also be two separating blades 420, with the two separating blades 420 located on the side of the peeling hole 411 adjacent to the moving body 100 and on the side of the peeling hole 411 away from the moving body 100, respectively.

[0059] Considering that the tubular auxiliary material 20 is a pipe with internally solidified resin, its own weight is relatively large, making overall handling difficult. Therefore, in some embodiments, such as Figure 3 and Figure 4 As shown, the auxiliary material removal equipment also includes a cutting component 500, which is located at the rear end of the peeling block 410 along the forward direction. The cutting component 500 is used to cut the tubular auxiliary material 20 extending from the peeling hole 411 in a direction perpendicular to the forward direction, thereby cutting the tubular auxiliary material 20 into multiple segments to facilitate subsequent cleaning and transportation.

[0060] When there are two peeling components 400, there can be two slitting components 500, with each of the two slitting components 500 corresponding to one of the two peeling components 400. For example, each slitting component 500 includes a telescopic component and a cutter driven by the telescopic component.

[0061] When there are two peeling components 400, there can be one slitting component 500. The slitting component 500 is used to cut the tubular auxiliary material 20 extending from the peeling holes 411 of the two peeling components 400. For example, the slitting component 500 includes a cutter 510 and a moving component 520. The moving component 520 drives the cutter 510 to move between the positions of the two peeling holes 411, thereby cutting the tubular auxiliary material 20 extending from the two peeling holes 411. Furthermore, a motor can also be used to drive the cutter 510 to rotate, improving the efficiency of the cutter 510 in cutting the tubular auxiliary material 20.

[0062] In some embodiments, both the first rotating member 210 and the second rotating member 220 are drive wheels. That is, both the first rotating member 210 and the second rotating member 220 are driven to rotate actively by drive components such as motors, which can avoid slippage and improve operational stability.

[0063] In some other embodiments, one of the first rotating member 210 and the second rotating member 220 is a driving wheel, and the other is a pressure wheel. That is, one rotating member is driven by a motor or other driving component to rotate actively, while the other rotating member follows without power. This saves one driving component and reduces production costs. In this embodiment, the distance between the first rotating member 210 and the second rotating member 220 can be adjusted by a spring, cylinder, or screw mechanism to ensure sufficient friction and avoid slippage.

[0064] According to another aspect of this disclosure, a moving device is also provided, which can be used in conjunction with any one of the cutting blade 300, the peeling assembly 400, and the slitting assembly 500 described above. Specifically, the moving device may include a moving body 100 and a traction assembly 200, wherein the moving body 100 is used to move on the inner wall surface of the blade half-shell. The traction assembly 200 is disposed on the moving body 100, and the traction assembly 200 includes a first rotating member 210 and a second rotating member 220 arranged vertically. The first rotating member 210 and the second rotating member 220 clamp and rotate the traction member to drive the moving device to move in the forward direction.

[0065] It should be noted that the traction component held by the first rotating member 210 and the second rotating member 220 can be the aforementioned sheet-like auxiliary material 10, or other ropes or guide plates, etc. For the specific structure of the moving body 100 and the traction assembly 200, please refer to the detailed description in the above embodiments, which will not be repeated here.
