Description

Technical Field

[0001] This invention relates to the field of nacelle cover transportation technology, and in particular to a wind turbine nacelle cover transportation system. Background Technology

[0002] As a crucial outer shell protecting the core components of a wind turbine generator (such as the generator and gearbox), the nacelle cover is typically characterized by its large size, heavy weight, and irregular shape (often curved or irregularly shaped). During transportation, the nacelle cover needs to be secured to the transport vehicle using specialized securing devices to prevent damage caused by road bumps, sudden braking, or cornering, which could result in shaking or collisions. Therefore, the reliability, stability, and compatibility of the securing devices directly affect the transportation safety of the nacelle cover.

[0003] Existing aircraft canopy transport securing devices mostly use traditional strapping tape in conjunction with manual or semi-automatic tightening devices for fixation, which has the following technical drawbacks:

[0004] 1. Traditional strapping tapes (such as nylon tapes and polyester tapes) are prone to permanent stretching or slippage and shortening under long-term stress or vibration, which causes the binding force to gradually decrease and the binding to loosen. Once the binding is loose, it cannot tighten automatically. Over time, this may lead to binding failure, which may result in surface scratches or even structural deformation or complete detachment, posing a serious safety hazard.

[0005] 2. Anti-return mechanisms (such as pawl-ratchet mechanisms) are mostly fixed installations and cannot be adjusted synchronously with the downward cushioning movement of the cabin cover. When the cabin cover jumps downward, the strapping may loosen instantly and then slide in the opposite direction, resulting in increased strapping force and increased binding force on the cabin cover, which may lead to damage.

[0006] 3. The surface of the nacelle canopy is mostly an irregular curved surface (such as raised, recessed or inclined areas). The fixing points of traditional binding devices are rigid structures, which cannot adapt to the different shapes of the nacelle canopy surface. During binding, local stress concentration is likely to occur, which will cause the surface of the nacelle canopy to be damaged due to excessive pressure. At the same time, the rigid fixing points cannot always be in contact with the surface of the nacelle canopy during vibration, which further aggravates the loosening of the binding and local wear.

[0007] Therefore, it is necessary to invent a wind turbine nacelle transport system to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide a wind turbine nacelle cover transportation system to solve the problem mentioned in the background art that traditional strapping tapes (such as nylon tapes and polyester tapes) are prone to permanent stretching under long-term stress or vibration, which leads to a gradual decrease in strapping strength and loosening of the strapping. Once the strapping is loose, it cannot be tightened automatically, and long-term accumulation may lead to strapping failure, which may result in surface scratches or even structural deformation or even complete detachment, posing serious safety hazards.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a wind turbine nacelle transport system, comprising:

[0010] Supporting devices are used to support the fuselage canopy;

[0011] A strapping assembly consisting of strapping tape, a check lock device, a tightening device, and an outer frame;

[0012] Cable ties are used in conjunction with check locks and tightening devices to secure the nacelle cover.

[0013] A check lock device is used to tighten and prevent the strapping from slipping back.

[0014] The tightening device includes an installation structure and a winding structure. The winding structure is installed on the vehicle body through the installation structure. The movable end of the strapping strap passes through the anti-return locking device and is connected to the winding structure. The winding structure is used to automatically rotate and drive the strapping strap to wrap around the winding structure located on the inner side below the engine compartment cover when the strapping strap on the engine compartment cover becomes loose. This, in conjunction with the anti-return locking device, tightens the strapping strap accordingly.

[0015] The outer frame is mounted on the vehicle body and is used to limit the height and horizontal sliding of the mounting and winding structures.

[0016] Optionally, the winding structure consists of a rotating device and a power storage device;

[0017] The rotating device includes a rotating column, a strapping limit structure installed on the outer end of the rotating column, and a positioning ring coaxially sleeved on the outer side of the rotating column. A guide slide is provided on the outer circumference of the rotating column, and a guide column that is slidably disposed in the guide slide is fixedly connected to the inner wall of the positioning ring.

[0018] The power storage device includes a drive device and an elastic device that move along the axial direction of the rotating column. The fixed end of the drive device is connected to the mounting structure, and the movable end of the drive device is connected to the outer circumference of the positioning ring. The inner end of the rotating column is rotatably equipped with an elastic device mounting plate, and the elastic device is sleeved on the outer side of the rotating column between the elastic device mounting plate and the positioning ring. The outer end of the rotating column is connected to the strapping.

[0019] Optionally, the outer end of the rotating column is provided with a winding part, and the winding part is provided with a through hole through which the strapping tape can pass.

[0020] Optionally, the elastic device mounting plate is polygonal and has a correspondingly shaped directional cylinder on the outside. The directional cylinder is fixed to the mounting structure and has a guide channel for the drive device to pass through.

[0021] Optionally, the guide slide consists of a spiral slide and a horizontal slide. Both the inner and outer ends of the spiral slide and the horizontal slide are provided with guide ramps. When the guide column slides to the outer end of the spiral slide, the guide ramps guide the guide column into the horizontal slide. When the guide column slides to the inner end of the horizontal slide, the guide ramps guide the guide column into the spiral slide.

[0022] Optionally, a clamping plate is installed on the drive unit, and a check lock device is set on the upper part of the clamping plate and clamped on both sides of the cabin cover. The check lock device and the clamping plate move synchronously with the cabin cover.

[0023] Optionally, an elastic pad is installed at the lower inner end of the outer frame, which contacts the clamping plate and the lower surface of the mounting structure.

[0024] Optionally, two symmetrically arranged rotating rollers are rotatably installed at the opening of the strapping limit structure, and two symmetrically arranged frustum columns are rotatably installed inside the strapping limit structure.

[0025] Optionally, it may also include an anti-slip device, which includes;

[0026] Base plate;

[0027] Telescopic structures, which are provided in multiples and installed on the base plate and detached from the cabin cover, are used to limit the slippage of the straps;

[0028] The strapping plate, which is hinged to the top of the base plate, is used to pass through the straps and always keep the straps horizontal.

[0029] Optional, the telescopic structure includes:

[0030] The guide cylinder is fixedly installed at the bottom of the base plate;

[0031] An extension rod is inserted downward into the interior of the guide cylinder, and a compression spring is installed between the top of the extension rod and the inner top wall of the guide cylinder.

[0032] A rubber pad, hinged to the bottom of the extension rod, contacts the cabin canopy.

[0033] The technical effects and advantages of this invention are as follows:

[0034] 1. The winding structure of this invention can drive the strapping to tighten and bind the cabin cover. When the strapping undergoes permanent tensile deformation or the binding of the cabin cover becomes loose or fails to secure due to slippage of the strapping, the winding structure automatically rotates and winds the strapping, effectively maintaining the binding force of the strapping. This avoids the cabin cover from shaking and being damaged during transportation due to loose binding, and reduces manual intervention, thus improving the safety and convenience of transportation.

[0035] 2. The anti-return locking device of the present invention can follow the movement of the cabin cover and completely lock the strapping tape when the anti-return locking device follows the movement of the cabin cover, so as to prevent the strapping tape between the two anti-return locking devices from tightening due to loosening during the movement of the cabin cover, and to prevent the strapping tape between the two anti-return locking devices from exerting excessive binding force on the cabin cover when the two anti-return locking devices move with the cabin cover, which would cause damage to the cabin cover.

[0036] 3. The anti-slip device of the present invention comes into contact with the upper surface of the cabin cover under the compression of the strapping. It can also adapt to different shapes of cabin covers by stretching and contracting, so that the strapping fits the cabin cover better and improves the fixing effect. At the same time, it can also avoid damage to the cabin cover due to excessive local stress caused by the irregular shape of the cabin cover. When the cabin cover jumps downward, it always stays in close contact with the cabin cover and keeps the strapping taut, preventing the strapping from slipping and shortening the distance due to loosening.

[0056] 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.

[0057] This invention provides, for example Figure 1-11 A wind turbine nacelle transport system is shown, comprising:

[0058] Support device 100 is used to support the nacelle cover. Support device 100 can be made of elastic materials such as rubber or elastic fibers. Traditional support devices 100 typically use hardwood boards or elastic support boards with cushioning functions. The functions and application scenarios of these two different support materials are also different: elastic support boards with cushioning functions are mainly used in harsh road conditions, frequent vibrations, or when long-term protection of the nacelle cover is required. They absorb and disperse vibrations and impacts during transportation, protecting the nacelle cover from damage. Hardwood boards are mainly used for transportation on flat roads where cost is sensitive, or when a temporary support structure needs to be quickly erected; hardwood boards are more economical. However, wind turbines are usually located in mountainous and rural plains, where harsh road conditions are common during transportation. Using hardwood boards may cause collisions and damage to the nacelle cover or scratches on the nacelle cover. Using elastic support boards is more advantageous, as they prevent damage when the transport vehicle travels on harsh road conditions. When the nacelle sways downwards, the support device 100 can cushion the downward sway of the nacelle. The nacelle (usually referring to the fiberglass shell of a wind turbine) is a large, thin-walled structure, which is prone to local damage due to external impacts on bumpy roads. If the elasticity of the support device 100 is small, the vibration and impact energy generated during transportation cannot be effectively absorbed and dissipated by the pad. The unabsorbed impact force will be transmitted between components (nacelle - pad - transport frame). The huge impact force will not only damage the nacelle, but may also cause the binding structure to be over-tightened or even break, or damage the transport frame itself. The elastic pad with a large compression range can better absorb and dissipate the huge impact force. It can also adaptively adjust the support force at each point through its own deformation, so that the support force at each point is always uniform. This avoids a certain support point being subjected to excessive force at a moment due to bumps. It cannot cushion the impact force through deformation, which would cause damage to the nacelle.

[0059] A strapping assembly consisting of strapping tape 200, anti-return locking device 500, tightening device 400, and outer frame 300;

[0060] The strapping 200 is used in conjunction with the anti-return locking device 500 and the tightening device 400 to secure the nacelle cover. The strapping 200 can be made of nylon webbing or high-strength polyester webbing, which has the characteristics of high strength, wear resistance and tensile strength, and is suitable for fixing needs in various complex environments.

[0061] The anti-return locking device 500 is used to tighten and prevent the cable tie 200 from sliding, thereby limiting the sliding direction of the cable tie 200. For example, existing rope tensioners limit the sliding of the cable tie 200. The anti-return locking device 500 also works in conjunction with the winding structure 420. During the tightening process of the tightening device 400, the cable tie 200 will not move in the opposite direction, ensuring real-time tightening adjustment of the cable tie 200.

[0062] The tightening device 400 includes a mounting structure 410 and a winding structure 420. The winding structure 420 is installed inside the outer frame 300 through the mounting structure 410 to ensure its stability. The movable end of the strapping 200 passes through the anti-return locking device 500 and is connected to the winding structure 420 to form a complete strapping system. The winding structure 420 is used to automatically rotate and drive the strapping 200 to wrap around the winding structure 420 when the strapping 200 on the cabin cover becomes loose, and cooperate with the anti-return locking device 500 to tighten the strapping 200 accordingly.

[0063] The winding structure 420 can drive the strapping 200 to tighten and effectively secure the cabin cover. When the strapping 200 undergoes permanent tensile deformation or the strapping 200 slips, causing the cabin cover to become loose or the fastening to fail, the winding structure 420 automatically rotates and winds the strapping 200, so that the strapping 200 is tightened in real time to maintain the strapping force of the strapping 200 on the cabin cover. This avoids the cabin cover from shaking and being damaged during transportation due to loose strapping, and reduces the number of manual interventions, thus improving the safety and convenience of transportation.

[0064] The outer frame 300 is mounted on the vehicle body and is used to restrict the vertical and horizontal positions of the mounting structure 410 and the winding structure 420. In the initial state, the upper surfaces of the mounting structure 410 and the winding structure 420 are in contact with the inner top wall of the outer frame 300, thereby preventing the mounting structure 410 and the winding structure 420 from rising. At the same time, the outer frame 300 is provided with a limiting block inside to restrict the horizontal sliding of the mounting structure 410, so as to prevent the mounting structure 410 and the winding structure 420 from detaching from the outer frame 300 under the pull of the strapping 200.

[0065] The working principle of this embodiment is as follows:

[0066] The mounting structure 410 is installed inside the outer frame 300, and then the outer frame 300 is installed on the vehicle body. Two sets of tightening devices 400 are symmetrically arranged on the left and right sides of the transport vehicle. Then, the strapping 200 is wrapped around the outside of the cabin cover and passes through the anti-return locking device 500 and the winding structure 420. Then, the strapping 200 is manually tightened to effectively bind and secure the cabin cover. The anti-return locking device 500 prevents the strapping 200 from retracting. Then, the strapping 200 is tied to the winding structure 420. Finally, the winding structure 420 is adjusted to the initial position.

[0067] During operation, if the strapping 200 becomes longer due to permanent stretching deformation, or if the strapping 200 slips, causing the fuselage cover to loosen or become unsecured, the winding structure 420 will automatically rotate to wrap the strapping 200, whose end is fixed to the winding structure 420, around the circumference of the winding structure 420, thereby achieving real-time tightening of the strapping 200 and ensuring the binding force of the strapping 200.

[0068] In this invention, the winding structure 420 can be implemented by a motor drive; the anti-reverse locking device 500 can be an existing anti-reverse structure (such as a rope tensioner); the above-mentioned existing equipment can achieve the basic effect of this invention.

[0069] Existing technologies mostly employ motor-driven winding structures 420. However, motor-driven winding structures 420 also have certain drawbacks. For example, they require the cooperation of various sensors and motor anti-backlash mechanisms (such as motor brakes), resulting in higher costs and inconvenient maintenance. Their stability is particularly problematic in harsh environments during long-distance transportation. If the motor-driven winding structure 420 fails, the engine cover may slide during transportation, causing minor impacts or even falling off, posing a safety hazard.

[0070] Therefore, the winding structure 420 with the following special structure adopted in this invention can automatically complete the real-time tightening of the strapping 200 through a simple and stable mechanical structure with low cost and high stability, ensuring the effective binding and fastening of the strapping 200 to the cabin cover.

[0071] In some embodiments of the present invention, reference is made to... Figure 2-9 As shown, the winding structure 420 consists of a rotating device 421 and a power storage device 422;

[0072] The rotating device 421 includes a rotating column 4211, a strapping limit structure 4216 installed on the outer end of the rotating column 4211, and a positioning ring 4212 coaxially sleeved on the outer side of the rotating column 4211. The positioning ring 4212 is connected to the power storage device 422. A guide slide 4213 is provided on the outer circumference of the rotating column 4211. A guide column 4214 is fixedly connected to the inner wall of the positioning ring 4212 and slidably disposed in the guide slide 4213. The guide slide 4213 is used to guide the guide column. 4214 slides, and when the guide post 4214 slides along the guide slide 4213, it drives the rotating post 4211 to rotate; the cross-section of the strapping tape limiting structure 4216 is a U-shaped opening with the horizontal opening inward, that is, it forms a cylindrical structure with one end open, ensuring that the strapping tape 200 will not come off the rotating post 4211 under the pull of external force. It not only guides the strapping tape 200, but also ensures that the strapping tape 200 remains neat and orderly during the winding process, ensuring the tightness and firmness of the strapping effect;

[0073] The rotating column 4211 and the positioning ring 4212 are matched to ensure that the rotating column 4211 can move stably along the predetermined trajectory and prevent the rotating column 4211 from deviating during sliding rotation.

[0074] Since the positioning ring 4212 is connected to the power storage device 422, the positioning ring 4212 is restricted from rotating and moving by the power storage device 422. When the rotating column 4211 is pushed by the power storage device 422, the guide column 4214 slides along the guide slide 4213, and the rotating column 4211 is driven to rotate when the guide column 4214 slides, so that the rotating column 4211 wraps the strapping 200 around the circumference of the winding structure 420 during the rotation.

[0075] When the strapping 200 is wrapped around the rotating column 4211, since the rotating column 4211 is located inside the lower part of the cabin cover, the strapping 200 wrapped around the rotating column 4211 will exert an outward pulling force on the rotating column 4211.

[0076] The power storage device 422 includes a drive device 4221 and an elastic device 4222, which are arranged parallel to the rotating column 4211 and move along the axial direction of the rotating column 4211. The fixed end of the drive device 4221 is connected to the mounting structure 410 to ensure its stability and reliability. The movable end of the drive device 4221 is connected to the outer circumference of the positioning ring 4212 to achieve precise transmission and positioning functions. The inner end of the rotating column 4211 is rotatably provided with an elastic device mounting plate 4223 for supporting and fixing the elastic device 4222. The elastic device 4222 is sleeved on the elastic device. The outer side of the rotating column 4211 between the mounting plate 4223 and the positioning ring 4212 ensures that the elastic device 4222 will not shift or be damaged during operation. The mounting plate 4223 of the elastic device is equipped with balls to reduce the friction between the mounting plate 4223 of the elastic device and the rotating column 4211. The elastic device 4222 provides the necessary energy storage and release functions through elastic deformation. The outer end of the rotating column 4211 is connected to the strapping 200 to ensure the coordinated operation and high efficiency of the entire system, while improving the overall durability and ease of operation of the system.

[0077] In this embodiment, the drive device 4221 can be implemented using various existing technologies such as linear motors, hydraulic rods, or electric push rods;

[0078] In this embodiment, the elastic device 4222 can be implemented using various existing structures such as springs, disc springs, and shape memory metals;

[0079] The working principle of this embodiment is as follows:

[0080] Start the drive device 4221, causing the drive device 4221 to drive the positioning ring 4212 to slide inward. When the positioning ring 4212 slides, it squeezes the elastic device 4222, causing the elastic device 4222 to compress and store force, and drive the rotating column 4211 to slide to the initial position. After the rotating column 4211 slides to the initial position, the pushing force applied by the elastic device 4222 to the rotating column 4211 is always balanced with or slightly greater than the outward pulling force applied by the strapping 200 to the rotating column 4211.

[0081] If the strapping 200 becomes longer due to permanent tensile deformation, or if the strapping 200 slips, causing the cabin cover to loosen or become unsecured, the pulling force of the strapping 200 on the rotating column 4211 will decrease, and the elastic force of the elastic device 4222 will be released. This will cause the elastic device 4222 to push the rotating column 4211 to move inward relative to the positioning ring 4212. This will cause the guide column 4214 inside the positioning ring 4212 to slide outward along the guide slide 4213 on the rotating column 4211. When the rotating column 4211 slides along the guide slide 4213, it will drive the rotating column 4211 to rotate. When rotating, the rotating column 4211 will wrap around the circumference of the winding structure 420, so that the strapping 200 maintains the binding force on the cabin cover.

[0082] In some embodiments of the present invention, in order to properly guide the sliding of the guide post 4214 and drive the rotating post 4211 to rotate when the guide post 4214 slides along the guide slide 4213, refer to Figure 6 As shown, the guide slide 4213 consists of a spiral slide 4218 and a horizontal slide 4217. Both the inner and outer ends of the spiral slide 4218 and the horizontal slide 4217 are provided with guide ramps 4219. The guide ramps 4219 are designed to facilitate the movement of the guide post 4214 between the spiral slide 4218 and the horizontal slide 4217. When the guide post 4214 slides to the outer end of the horizontal slide 4217, it contacts the outer guide ramp 4219. 4219 guides the guide post 4214 into the spiral slide 4218. When the guide post 4214 slides to the inner end of the spiral slide 4218, it contacts the inner end guide ramp 4219. The guide ramp 4219 guides the guide post 4214 into the horizontal slide 4217. The corners on both sides of the guide ramp 4219 are staggered, so that the guide post 4214 can smoothly pass the corresponding corners under the action of the ramp, avoiding jamming or collision, thereby achieving a smooth sliding transition.

[0083] The working principle of this embodiment is as follows:

[0084] When the guide post 4214 slides along the horizontal slide rail 4217 to the outer end, it will contact the guide ramp 4219 located at the outer end. The outer end guide ramp 4219 is inclined into the spiral slide rail 4218, so that the guide post 4214 is guided into the spiral slide rail 4218 under the action of the guide ramp 4219. The outer end guide ramp 4219 can also restrict the guide post 4214 from entering the horizontal slide rail 4217, and drive the rotating post 4211 to rotate when sliding in the horizontal slide rail 4217, and wrap the strapping 200 during the rotation of the rotating post 4211.

[0085] When the guide post 4214 slides to the inner end of the spiral slide 4218, it will contact the inner guide ramp 4219. The inner guide ramp 4219 is inclined into the horizontal slide 4217. Guided by the guide ramp 4219, the guide post 4214 enters the interior of the horizontal slide 4217. The inner guide ramp 4219 can also restrict the guide post 4214 from entering the spiral slide 4218.

[0086] When the guide column 4214 slides to or near the outer end of the horizontal slide rail 4217, the driver can drive the rotating column 4211 and the positioning ring 4212 to slide to the position where the strapping 200 is not tightened through the drive device 4221, and then repeat the initial binding operation.

[0087] In some embodiments of the present invention, for wrapping and binding the strapping 200, refer to Figure 8 As shown, the outer end of the rotating column 4211 is configured as a detachable winding part 4215. The winding part 4215 passes radially through the strapping tape limiting structure 4216 and is rotatably connected to the strapping tape limiting structure 4216. The winding part 4215 is cylindrical, and its diameter can be adjusted according to actual needs. The winding part 4215 is provided with a through hole through which the strapping tape 200 can pass. When the rotating column 4211 rotates, it drives the strapping tape 200 to wrap around the circumference of the winding part 4215.

[0088] In some embodiments of the present invention, in order to guide the elastic device mounting plate 4223 and limit the rotation of the elastic device mounting plate 4223, refer to Figure 3 and Figure 4 As shown, the elastic device mounting plate 4223 is polygonal and has a correspondingly shaped guide tube 4225 on its outer side. The guide tube 4225 not only guides and restricts the rotation of the elastic device mounting plate 4223, but also prevents the elastic device 4222 from interfering with the rotating column 4211. The guide tube 4225 is fixed on the mounting structure 410 and has a guide channel 4226 for the drive device 4221 to pass through.

[0089] In some embodiments of the present invention, reference is made to... Figure 5 As shown, a clamping plate 4227 is installed on the drive unit 4221. The clamping plate 4227 provides an additional support surface, which helps to improve the clamping force and the safety of operation. The check lock device 500 is located on the upper end of the clamping plate 4227 and clamps on both sides of the cabin cover. The check lock device 500 and the clamping plate 4227 move synchronously with the cabin cover.

[0090] When the drive device 4221 is started, it drives the clamping plate 4227 to slide. When the clamping plate 4227 slides, it drives the anti-return locking device 500 to contact the nacelle cover. Under the action of the clamping plate 4227, the nacelle cover is clamped and fixed. The clamping plate 4227 also guides the anti-return locking device 500 to prevent the anti-return locking device 500 from deviating when sliding downward.

[0091] The anti-return locking device 500 and tightening device 400, which move synchronously with the cabin cover, can drive the strapping 200 to descend synchronously with the cabin cover during its descent due to turbulence. This prevents the strapping 200 between the two anti-return locking devices 500 from loosening during the downward movement of the cabin cover, thus preventing the strapping 200 from tightening due to the automatic rotation and winding of the winding structure 420. This also prevents the strapping 200 between the two anti-return locking devices 500 from being tightened by the automatic rotation of the winding structure 420 during the downward movement of the cabin cover, which could cause excessive binding force on the cabin cover and damage to the cabin cover.

[0092] In some embodiments of the present invention, reference is made to... Figure 7 As shown, an elastic pad 310 is installed at the lower inner end of the outer frame 300, which contacts the lower surface of the clamping plate 4227 and the mounting structure 410. When the clamping plate 4227 and the mounting structure 410 descend with the cabin cover, they squeeze the elastic pad 310, causing the elastic pad 310 to compress and store force. When the cabin cover rises, the elastic force of the elastic pad 310 is released, pushing the clamping plate 4227 and the mounting structure 410 to rise synchronously.

[0093] The inner surface of the outer frame 300 is bonded with a cushioning pad to cushion and absorb the impact force between the clamping plate 4227 and the mounting structure 410 and the outer frame 300 during resetting.

[0094] In some embodiments of the present invention, reference is made to... Figure 9 and Figure 8As shown, two symmetrically arranged rotating rollers 700 are rotatably installed at the opening of the strapping limit structure 4216, and two symmetrically arranged frustum columns 800 are rotatably installed inside the strapping limit structure 4216. The sliding direction of the strapping 200 is changed by the cooperation of the rotating rollers 700 and the frustum columns 800. At the same time, the friction of the strapping 200 during sliding is reduced by rotation, and the strapping 200 is unfolded.

[0095] In some embodiments of the present invention, in order to adapt to the curved surfaces of the cabin canopy with different shapes and prevent the strapping straps 200 from slipping, and at the same time to avoid damage to the cabin canopy due to excessive local stress caused by the irregular shape of the cabin canopy, refer to Figure 10 As shown, the anti-slip device 600 includes:

[0096] The base plate 610 serves as the fundamental support for the entire component, ensuring its stability and robustness.

[0097] Multiple telescopic structures 620 are provided and installed at the bottom of the base plate 610 in contact with the nacelle canopy. By telescopically adapting to nacelle canopies of different sizes and shapes, the adaptability and flexibility are improved.

[0098] The strapping plate 630 is hinged to the top of the base plate 610 and is used for the strapping 200 to pass through. It rotates under the pressure of the strapping 200. The rotation of the strapping plate 630 adjusts the strapping 200 to a horizontal position and prevents the strapping 200 from tilting to one side.

[0099] The anti-slip device 600 contacts the upper surface of the cabin cover under the pressure of the strapping 200, and can adapt to the curved surface of the cabin cover of different shapes through the telescopic structure 620. The telescopic structure 620, in conjunction with the rotation of the strapping plate 630, keeps the strapping 200 horizontal, preventing the strapping 200 from tilting and sliding in the tilting direction, making the strapping fit the cabin cover more closely and improving the fixing effect. At the same time, it can also avoid damage to the cabin cover due to excessive local stress caused by the irregular shape of the cabin cover. And when the cabin cover slides down, it always keeps in close contact with the cabin cover and keeps the strapping 200 taut.

[0100] The working principle of this embodiment is as follows:

[0101] The strap plate 630 rotates relative to the base plate 610 under the pressure of the strapping strap 200, keeping the strapping strap 200 horizontal. Then, under the action of the strapping strap 200, the telescopic structure 620 is compressed, causing multiple telescopic structures 620 to extend and retract according to the shape of the cabin canopy.

[0102] In some embodiments of the present invention, reference is made to... Figure 11 As shown, the telescopic structure 620 includes:

[0103] Guide cylinder 621, which is fixedly installed at the bottom of base plate 610;

[0104] An extension rod 622 is slidably inserted into the guide cylinder 621. The extension rod 622 and the guide cylinder 621 work together to achieve the telescopic function. The guide cylinder 621 guides the sliding of the extension rod 622. A compression spring 623 is installed between the top of the extension rod 622 and the inner top wall of the guide cylinder 621. The compression spring 623 provides elastic restoring force, so that the extension rod 622 can automatically return to its original position after being subjected to external force. It also applies a downward squeezing force to the rubber pad 624, so that the rubber pad 624 is always in contact with the cabin cover and restricts the sliding of the anti-slip device 600.

[0105] The rubber pad 624 is hinged to the bottom of the extension rod 622 and contacts the nacelle cover. The tilt angle and direction angle of the rubber pad 624 can be flexibly adjusted through the hinge point to ensure the best contact surface between the rubber pad 624 and the nacelle cover, thereby improving contact stability and shock absorption effect.

[0106] The working principle of this embodiment is as follows:

[0107] During extension and retraction, the extension rod 622 slides upward along the guide cylinder 621 under the action of the compressive force, and compresses the compression spring 623, causing the compression spring 623 to compress and store force.

[0108] The working method of this invention:

[0109] The mounting structure 410 is installed inside the outer frame 300, and then the outer frame 300 is installed on the vehicle body. Two sets of tightening devices 400 are symmetrically arranged on the left and right sides of the transport vehicle. Then, the strapping 200 is wrapped around the outside of the cabin cover and passes through the anti-return locking device 500 and the winding structure 420. Then, the strapping 200 is manually tightened to effectively bind and secure the cabin cover. The anti-return locking device 500 prevents the strapping 200 from retracting. Then, the strapping 200 is tied to the winding structure 420.

[0110] Start the drive device 4221, causing the drive device 4221 to drive the positioning ring 4212 to slide inward. When the positioning ring 4212 slides, it squeezes the elastic device 4222, causing the elastic device 4222 to compress and store force, and drive the rotating column 4211 to slide to the initial position. After the rotating column 4211 slides to the initial position, the pushing force applied by the elastic device 4222 to the rotating column 4211 is always balanced with or slightly greater than the pulling force applied by the strapping strap 200 to the rotating column 4211. In the strapping state, the elastic device 4222 is always in the stored force state.

[0111] When the strapping 200 undergoes permanent tensile deformation, or when the strapping 200 slips, causing the fuselage cover to loosen or become unsecured, the elastic force of the elastic device 4222 will be released. This will cause the elastic device 4222 to push the rotating column 4211 to move inward relative to the positioning ring 4212. At this time, the guide column 4214 slides along the horizontal slide rail 4217. When the guide column 4214 slides to the outer end along the horizontal slide rail 4217, it will contact the guide ramp 4219 located at the outer end. Upon contact, the outer end guide ramp 4219 is inclined into the spiral slide 4218, so that the guide post 4214 is guided into the spiral slide 4218 under the action of the guide ramp 4219. The outer end guide ramp 4219 can also restrict the guide post 4214 from entering the horizontal slide 4217, and drive the rotating post 4211 to rotate when sliding in the horizontal slide 4217, and wrap the binding tape 200 during the rotation of the rotating post 4211.

[0112] When the guide column 4214 slides to or near the outer end of the horizontal slide rail 4217, the driver can drive the rotating column 4211 and the positioning ring 4212 to slide to the position where the strapping 200 is not tightened through the drive device 4221, and then loosen the strapping 200 by the rotating column 4211. The driver then wraps the strapping 200 around the outside of the rotating column 4211 once, and after wrapping it once, drives the drive device 4221 again, causing the drive device 4221 to drive the positioning ring 4212 to slide back to the initial position. When the positioning ring 4212 slides, it compresses the elastic device 4222, putting the elastic device 4222 into a stored state, and driving the rotating column 4211 to slide back to the initial position. When the rotating column 4211 slides, the guide column 4214 slides along the spiral slide rail 4218 to the inner end of the spiral slide rail 4218, so that the rotating column 4211 applies a tightening force to the strapping 200.

[0113] The strapping plate 630 rotates relative to the base plate 610 under the pressure of the strapping strap 200, keeping the strapping strap 200 horizontal. Then, under the action of the strapping strap 200, the telescopic structure 620 is compressed, causing multiple telescopic structures 620 to extend and retract according to the shape of the cabin canopy. During extension and retraction, the extension rod 622 slides upward along the guide cylinder 621 under the action of compression, and compresses the compression spring 623, causing the compression spring 623 to compress and store force.

[0114] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
