Description

Technical Field

[0001] This invention relates to the field of wind turbine blade production equipment technology, specifically to a web plate transfer vehicle and an anti-tipping device. Background Technology

[0002] In the field of wind turbine blade manufacturing, the web, as the core load-bearing component of the blade, directly affects the overall structural strength and operational safety of the blade. During the blade production process, the prefabricated web needs to be transferred from the storage station to the main forming station. Currently, vertical web transfer carts are commonly used for this transfer.

[0003] To facilitate the hoisting and placement of the web plates, existing web plate transport vehicles typically reserve a gap of approximately 100mm based on the width of the web plate's PS (polystyrene) flange. This results in a significant installation gap between the web plate and the transport vehicle's support frame. During transport, the web plate is prone to swaying, shifting, or even tipping along the chord direction, frequently colliding and being squeezed against the transport vehicle's side columns, causing defects such as delamination, material shortages, and surface damage. These defects not only require time-consuming and labor-intensive repairs, increasing production costs, but also reduce the structural integrity of the web plate, affecting the overall quality and service life of the wind turbine blades.

[0004] A search revealed that existing technologies lack dedicated anti-swaying and anti-tipping clamping and fixing mechanisms for the vertical transfer of the web plate, thus failing to fundamentally solve the technical problems of web plate chordal swaying and easy damage during transfer. Summary of the Invention

[0005] The purpose of this invention is to provide a web plate transfer vehicle and an anti-tipping device to overcome the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a web plate transfer vehicle and an anti-tipping device, comprising a transfer vehicle, a web plate storage bracket on the transfer vehicle, a web plate body placed in the middle of the web plate storage bracket, and a clamping device provided between the two. The web plate storage support includes columns on both sides of the web plate body, and a clamping device is installed on the columns. The clamping device includes a second guide rail fixed to one side of the column. One side of the second guide rail is connected to a conformal plate via a lifting pin. A connecting rod is provided at the upper end of the lifting pin, and one end of the connecting rod is connected to a chord wheel assembly. The chord wheel assembly is connected to the column via a pneumatic rotating shaft.

[0007] In the above-mentioned process, the web plate storage bracket provides the installation base, and the clamping device, guide rail 2, lifting pin, conformal plate, connecting rod, chord wheel assembly and pneumatic rotating shaft cooperate to clamp and fix the web plate body, preventing the web plate body from tipping over and chordally swaying during transportation.

[0008] In a web plate transfer vehicle and anti-tipping device according to an embodiment of the present invention, the middle part of the guide rail two is provided with an adjustment hole adapted to the lifting pin; the upper and lower ends of the adjustment hole are both semi-circular structures; and a guide rail one adapted to the connecting rod is provided on one side of the guide rail two.

[0009] In the above description, the adjustment hole is used to adjust the height of the lifting pin and the conformal plate; the semi-circular end facilitates the smooth sliding of the lifting pin; the guide rail is used to guide the connecting rod and ensure the stable movement of the connecting rod.

[0010] In a web plate transfer vehicle and anti-tipping device according to an embodiment of the present invention, the top of the conforming plate is provided with an auxiliary clamping assembly and an anti-slip layer; the anti-slip layer is made of rubber, and a plurality of anti-slip strips are provided on the top of the anti-slip layer; the top of the anti-slip layer is parallel to the top of the conforming plate.

[0011] In the above, the anti-slip layer is used to increase the friction between the conformal plate and the web body to prevent the web body from slipping; the auxiliary clamping assembly is used to further limit the web body and improve clamping stability.

[0012] In a web plate transfer vehicle and anti-tipping device according to an embodiment of the present invention, the top of the conformal plate is parallel to the bottom of the web plate body.

[0013] The above-mentioned measures ensure that the conformal plate fits snugly against the bottom surface of the main body of the web plate, thereby ensuring that the main body of the web plate is subjected to uniform force and preventing the bottom of the main body of the web plate from being suspended and deformed.

[0014] In a web plate transfer vehicle and anti-tipping device according to an embodiment of the present invention, the auxiliary clamping assembly includes a movable hole opened on the top of the conformal plate, and a clamping claw is adapted to be connected inside the movable hole. The top of the clamping claw has a clamping part that is bent toward the web plate body.

[0015] In the above description, the movable hole provides the clamping claw with a space to move; the clamping claw is used to hold the edge of the web body and limit the chordal displacement of the web body.

[0016] In a web plate transfer vehicle and anti-tipping device according to an embodiment of the present invention, a limiting slider is fixedly connected to the middle of the clamping claw, and the end of the limiting slider is provided with a rounded corner; a limiting groove adapted to the limiting slider is opened inside the moving hole.

[0017] In the above, the limiting slider and the limiting groove cooperate to limit the movement trajectory of the clamping claw and prevent the clamping claw from deflecting; the rounded corners reduce the frictional resistance when the limiting slider slides.

[0018] In a web plate transfer vehicle and anti-tipping device according to an embodiment of the present invention, a support spring is fixedly connected between the limiting groove and the limiting slider.

[0019] In the above description, the support spring provides elastic thrust to the limiting slider and the clamping claw, enabling the clamping claw to adaptively grip the web body and maintain a stable clamping state.

[0020] In a web plate transfer vehicle and anti-tipping device according to an embodiment of the present invention, the chord wheel assembly includes a bracket and a chord wheel, and the orientation of the chord wheel is perpendicular to the axial direction of the web plate body.

[0021] In the above description, the chord wheel assembly is arranged perpendicular to the axial direction of the web body and is used to limit the chord direction of the web body, thereby suppressing chord swaying and tipping of the web body during transportation.

[0022] In a web plate transfer vehicle and anti-tipping device according to an embodiment of the present invention, the first guide rail is a U-shaped round-headed guide rail, and the opening of the first guide rail is arranged facing the connecting rod.

[0023] As mentioned above, the U-shaped round head structure can reduce the friction of the connecting rod movement, avoid jamming, and improve the smoothness of the clamping device's operation and service life.

[0024] In a web plate transfer vehicle and anti-tipping device according to an embodiment of the present invention, the clamping device has a symmetrical structure and is respectively provided on the columns on both sides of the web plate body, and the chord wheel assemblies on both sides simultaneously clamp the web plate body.

[0025] In the above, the symmetrical arrangement ensures that the main body of the web plate is subjected to balanced forces, achieves centered positioning, and further improves the anti-tipping and anti-swaying effect during transportation.

[0026] Compared with the prior art, the beneficial effects of the present invention are: a web plate transfer vehicle and an anti-tipping device: 1. By forming a double clamping and positioning mechanism between the chord wheel assembly and the conformal plate, the web plate is stably constrained from both sides, completely eliminating the problems of chord swaying, offset and tipping of the web plate during transportation, and significantly improving transportation safety.

[0027] 2. The web plate is made of nylon chord wheel and rubber anti-slip layer in flexible contact, and is combined with elastic self-adaptive clamping structure. There is no rigid compression or scratches, which avoids defects such as web plate delamination, bumps and indentations from the root and reduces maintenance costs.

[0028] 3. With the cooperation of guide rail one and guide rail two and adjustment hole, it can be adapted to clamp web plates of different thicknesses and curvatures; the pneumatic rotary shaft drive ensures smooth operation and enables quick clamping and loosening, adapting to the needs of transporting multiple types of web plates.

[0030] 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.

[0031] Example: Figure 1-7 As shown, a web plate transfer vehicle and anti-tipping device include a transfer vehicle body. The transfer vehicle body is a segmented splicing structure with a single segment length of no more than 6m. The segments are evenly distributed and can effectively disperse the load of the web plate body 3 and the clamping device 2, avoid local stress concentration, and meet the load-bearing requirements of long-distance, large-size vertical transfer of wind turbine blade web plates.

[0032] Among them, the web plate storage bracket 1 is fixedly installed on the transfer vehicle. The web plate storage bracket 1 is evenly arranged along the axis of the transfer vehicle, and the distance between adjacent brackets is no more than 5m. While realizing load distribution, it provides a stable welding and installation support foundation for the clamping device 2.

[0033] The web plate storage bracket 1 has a web plate body 3 to be transported placed in the middle, and a clamping device 2 is set between the web plate body 3 and the web plate storage bracket 1. The web plate storage bracket 1 includes columns located on the left and right sides of the web plate body 3 respectively. The clamping devices 2 are symmetrically installed on the columns on both sides. The two sets of clamping devices 2 move synchronously to achieve symmetrical clamping and centered positioning of the web plate body 3, ensuring balanced force during the transport process.

[0034] In this embodiment, the clamping device 2 includes a guide rail 21 fixedly installed on the inner side of the column. The guide rail 21 provides guidance and limiting constraints in the height direction for the conforming plate 22 and the lifting pin 23, retaining only a single degree of freedom in the vertical direction, ensuring that the conforming plate 22 only moves up and down in the height direction and does not undergo chordal offset.

[0035] In this embodiment, an adjustment hole 211 is provided in the middle of the guide rail 21. The adjustment hole 211 is slidably adapted to the lifting pin 23. The upper and lower ends of the adjustment hole 211 are both set as semi-circular structures. This structure can reduce the frictional resistance when the lifting pin 23 slides, avoid jamming, and facilitate the smooth sliding and stable positioning of the lifting pin 23 in the adjustment hole 211, adapting to web body 3 with different heights and thicknesses.

[0036] In this embodiment, a guide rail 212 is also fixedly provided on one side of the guide rail 21, which is slidably adapted to the connecting rod 24. The guide rail 212 adopts a U-shaped round head structure, which provides stable swing and sliding guidance for the connecting rod 24, constrains the movement trajectory of the connecting rod 24, ensures that the clamping action of the chord wheel assembly 26 is accurate and stable, and improves the reliability of the chord limit.

[0037] In this embodiment, the guide rail 21 is movably connected to the conformal plate 22 through the lifting pin 23. The profile of the conformal plate 22 matches the profile of the web storage bracket 1. The top of the conformal plate 22 is parallel to and closely fits the bottom of the web body 3, which can provide uniform and stable support for the bottom of the web body 3, and avoid deformation and cracking caused by the bottom of the web body 3 being suspended.

[0038] In this embodiment, an auxiliary clamping component 221 and an anti-slip layer 222 are provided on the top of the conformal plate 22; the anti-slip layer 222 is made of rubber, which is soft and will not scratch the surface of the web body 3, while having a high coefficient of friction. Among them, the top of the anti-slip layer 222 is provided with several sets of anti-slip strips. The anti-slip strips can further increase the friction between the anti-slip layer and the web body 3, effectively suppressing the axial movement and slippage of the web body 3 during transportation. The top surface of the anti-slip layer 222 is parallel to the top surface of the conformal plate 22, ensuring full contact with the bottom surface of the web body 3 and uniform force distribution.

[0039] In this embodiment, the auxiliary clamping assembly 221 includes a movable hole 2211 formed on the top of the conformal plate 22. The movable hole 2211 provides installation and movement space for the clamping claw 2212 and limits the horizontal movement stroke of the clamping claw 2212. The clamping claw 2212 is fitted inside the movable hole 2211. The top of the clamping claw 2212 has an integrally formed clamping part that bends towards the web body 3. The clamping part is adapted to the edge contour of the web body 3 and is used to hold the edge of the web, forming a bottom lateral constraint, which further improves the placement stability of the web body 3.

[0040] It should be noted that a limiting slider 2213 is fixedly connected to the middle of the gripper 2212. The end of the limiting slider 2213 is provided with a rounded corner. The rounded corner structure can reduce sliding friction and prevent the limiting slider 2213 from scratching the inner wall of the limiting groove 2214 during movement.

[0041] The moving hole 2211 has a limiting groove 2214 inside that is adapted to the limiting slider 2213. The limiting groove 2214 and the limiting slider 2213 cooperate with each other to limit the movement direction of the clamping claw 2212 and prevent the clamping claw 2212 from deflecting or falling off.

[0042] It should be noted that a support spring 2215 is fixedly connected between the limiting slide groove 2214 and the limiting slider 2213. The support spring 2215 is always in a pre-compressed state, which can continuously provide elastic thrust to the gripper 2212 in the direction of the web body 3, so that the gripper 2212 has elastic adaptive gripping capability, can automatically adapt to web body 3 of different thicknesses, and maintain a tight gripping state without external force intervention, thereby improving the safety redundancy of the device.

[0043] In this embodiment, the upper end of the lifting pin 23 is fixedly connected to the connecting rod 24. The connecting rod 24 serves as a transmission component, used to transmit the driving force of the pneumatic rotating shaft 25, and simultaneously control the clamping angle of the chord wheel assembly 26 and the support height of the conformal plate 22, achieving linkage between the upper clamping and the lower support. One end of the connecting rod 24 is connected to the chord wheel assembly 26; the chord wheel assembly 26 is connected to the column via the pneumatic rotating shaft 25 and driven therethrough. The pneumatic rotating shaft 25 is fixedly installed on the side wall of the column, and the installation position is connected by opening holes in the column and fastening bolts. The installation is firm and the transmission is stable, which can drive the connecting rod 24 to complete the rotational swing at a set angle, realizing the automatic clamping and loosening action of the clamping device 2. The operation is convenient and efficient.

[0044] The chord wheel assembly 26 includes a bracket and a chord wheel. The chord wheel is oriented perpendicular to the axial direction of the web body 3 and is used to limit and flexibly clamp the web body 3 in the chord direction, restricting the web body 3 from swaying or shifting in the chord direction during transportation, and fundamentally preventing the web body 3 from colliding with the column of the web storage bracket 1.

[0045] In this embodiment, the chord wheel can be made of nylon. Nylon is flexible and wear-resistant, and it makes flexible rolling contact with the web body 3. It will not cause rigid compression, scratches, indentations or other damage to the surface of the web body 3. At the same time, it can effectively absorb vibration and impact during the transfer process, avoid defects such as delamination and material shortage in the web body 3, and significantly improve the product quality during the web transfer process.

[0046] The working principle of this embodiment is as follows: First, the pneumatic rotating shaft 25, as the core power component, receives external air and generates a rotational motion at a set angle, driving the connecting rod 24 to swing precisely along the guide rail 212. This, in turn, drives the chord wheel assembly 26 to move synchronously toward the web body 3. The two chord wheel assemblies 26 form a symmetrical clamping force, stably limiting the web body 3 to the central position and strictly restricting the chord swaying and tilting tendency of the web body 3 during transportation. The guide rail 212 provides stable guidance for the connecting rod 24, ensuring that the clamping action is linear, precise, and does not deviate.

[0047] Secondly, the guide rail 21 and the lifting pin 23 cooperate with each other to allow the conformal plate 22 to rise and fall adaptively in the vertical direction. The top surface of the conformal plate 22 is always parallel and in contact with the bottom surface of the web body 3, providing uniform support for the bottom of the web body 3 and avoiding uneven deformation of the bottom. The anti-slip layer 222 on the top of the conformal plate 22 increases the friction of the contact surface and prevents the web body 3 from sliding axially. Under the elastic action of the support spring 2215, the auxiliary clamping component 221 automatically hugs the edge of the web body 3 through the clamping claw 2212, forming a lateral elastic constraint at the bottom, which further enhances the positioning stability.

[0048] Finally, the chord wheel assembly 26 is made of nylon and makes flexible contact with the web body 3. With the help of the elastic auxiliary clamping structure, there is no rigid impact or squeezing throughout the process, which can effectively avoid defects such as delamination, scratches and indentations in the web body 3. The upper part is limited by the chord, the lower part is supported and anti-slip, and the sides are elastically clamped to form a three-dimensional protection system. The action is automated, adaptable to multiple specifications of webs, and stable and reliable operation. It completely solves the technical problems of shaking, tipping and easy product damage caused by excessive reserved gaps in traditional web transfer vehicles.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
