Description

Technical Field

[0001] This invention relates to the field of wind turbine blade handling technology, and more particularly to a wind turbine blade demolding vacuum adsorption handling device with adaptive attitude adjustment. Background Technology

[0002] Wind turbine blades are the core components of wind turbine generators. Their internal structure typically consists of a shell and a web for support and load-bearing. The web is often made of glass fiber / carbon fiber composite material and formed in a mold using a vacuum injection process. Since the initial strength of the web after demolding is only 60% to 70% of its final strength, it exhibits high brittleness and extremely poor impact resistance. Therefore, the demolding and handling process places extremely high demands on the safety, stability, and intelligence level of the equipment.

[0003] In existing technologies, the demolding and handling of wind turbine blade webs mainly relies on manual labor in conjunction with simple lifting equipment or general handling fixtures, which has the following drawbacks: First, the width adjustment mechanism of existing handling equipment mostly adopts simple gear and rack rigid transmission. When adjusting the spacing to adapt to the width of the wind turbine blade web, a huge rigid impact force is generated when the support reaches the limit position or touches the wind turbine blade web. Since the newly demolded wind turbine blade web is extremely fragile, this uncontrollable impact can easily cause hidden cracks or even direct breakage of the wind turbine blade web, resulting in serious quality accidents and economic losses. Second, the wind turbine blade web mold has a curved layout with a wide root and a narrow tip, and there are obstacles such as vacuum tubes and cables densely distributed below the mold. If traditional equipment uses large-diameter wheels to improve obstacle crossing ability, it will result in an excessively high center of gravity and poor stability. If small wheels are used, it will be unable to pass through obstacles. Furthermore, when existing equipment crosses obstacles, the rigid impact during the lifting process is large, and the vibration is easily transmitted to the already adsorbed wind turbine blade, affecting its internal structural integrity. Summary of the Invention

[0004] To address the problems mentioned in the background section, the present invention adopts the following technical solution:

[0005] The wind turbine blade demolding vacuum adsorption and handling device with adaptive attitude adjustment includes a crossbeam, a left support and a right support, and a width adjustment mechanism.

[0015] Preferably, the damage prevention component further includes buffer cylinders symmetrically fixedly connected to the side walls of the left and right supports. A sliding plate is slidably connected to the inner wall of the buffer cylinder, and a crossbar is fixedly connected to the side wall of the sliding plate. One end of the crossbar passes through the side wall of the buffer cylinder and is fixedly connected to a buffer plate. A second spring is sleeved on the side wall of the crossbar. The two ends of the second spring are fixedly connected to the side wall of the sliding plate and the inner wall of the buffer cylinder, respectively. The buffer cylinder is connected to the sealed cavity through a connecting pipe. Both the buffer cylinder and the sealed cavity are filled with hydraulic oil.

[0016] Preferably, a speed sensor is fixedly connected to the side wall of the disk, and the speed sensor is electrically connected to the servo steering wheel through a PLC control circuit.

[0017] Preferably, the pulley assembly includes a mounting frame, an upper pulley, a side pulley, and an auxiliary pulley. The mounting frame is slidably sleeved on the side wall of the crossbeam, and the lower left support and the upper right support of the mounting frame are fixedly connected. The upper pulley is rotatably connected to the inner wall of the mounting frame, and the upper pulley rolls against the upper end of the crossbeam. The side pulley and the auxiliary pulley are both rotatably connected to the inner wall of the mounting frame.

[0018] Preferably, the side wall of the crossbeam is provided with a sliding groove, the side pulley is rolled and engaged in the sliding groove, and the auxiliary pulley rolls and fits against the side wall of the crossbeam.

[0019] Preferably, a lubrication assembly is installed on the mounting base. The lubrication assembly includes an oil pump cylinder fixedly connected to the lower end of the mounting base. A sliding plug is slidably connected to the inner wall of the oil pump cylinder. A one-way oil inlet pipe is fixedly connected to the lower end of the oil pump cylinder. The oil pump cylinder is connected to the slide groove through the one-way oil supply pipe.

[0020] Preferably, the lubrication assembly further includes a slider slidably connected to the inner wall of the oil pump cylinder, two vertical rods are fixedly connected to the lower end of the slider, and the lower ends of the two vertical rods are fixedly connected to the slide plug. A reciprocating screw is rotatably connected to the top of the oil pump cylinder, the side wall of the reciprocating screw is threadedly connected to the slider, and the lower end of the rotating shaft passes through the upper end of the oil pump cylinder and is fixedly connected to the reciprocating screw.

[0021] Preferably, two spring wheels are fixedly connected to the lower ends of both the left and right supports, and a lift is fixedly connected to both ends of both the left and right supports. Electric walking wheels and swivel wheels are fixedly connected to the lower ends of both the left and right supports, and the electric walking wheels and swivel wheels are all driven by the lift for lifting.

[0022] Preferably, an electric hoist is fixedly connected to the lower end of both the left and right supports, and a vacuum adsorption plate is suspended from the lower end of the electric hoist.

[0023] The present invention has the following beneficial effects:

[0024] 1. By designing the anti-damage component, the physical quantity of gear rotation is converted into a protection signal. When the buffer plate contacts the web of the wind turbine blade, hydraulic oil is squeezed into the sealing cavity, pushing the friction plate to press against the disk that rotates synchronously with the shaft, instantly increasing the rotational resistance. The speed sensor detects the sudden drop in disk speed and immediately feeds back to the PLC to control the servo steering wheel to stop urgently. This mechanism transforms the rigid collision at the end of the damping into a controllable flexible contact, reducing the impact force and avoiding damage to the web of the wind turbine blade due to misoperation or control delay, thus solving the long-standing pain point of hard contact in the industry.

[0025] 2. By using a single gear to simultaneously mesh with the racks on both sides, the mechanical structure forces the absolute synchronous movement of the left and right supports, avoiding the cumulative error and jamming risk that may occur if electrical synchronization is relied upon alone. At the same time, the rotation of the gear is linked to the clamping force of the friction plate, so that the damping feeling at the end of the width adjustment increases with the contact depth, achieving a force feedback effect similar to a clutch, and achieving smooth control without the need for complex force sensors.

[0026] 3. Using the width adjustment drive shaft as a power source, the reciprocating screw drives the sliding plug to reciprocate in the oil pump cylinder, realizing the function of width adjustment and lubrication. While the pulley assembly slides, lubricating oil is automatically and quantitatively delivered to the slide groove to precisely lubricate the side pulleys. This not only greatly reduces sliding resistance and ensures the smoothness of width adjustment, but also avoids the accumulation of contaminants such as release agents in the guide rail, extending the equipment maintenance cycle.

[0027] 4. By integrating servo steering wheels, spring wheels, electric walking wheels, omnidirectional wheels, and a lift, a multi-modal walking system was constructed. Under normal conditions, the low center of gravity of the servo steering wheels and spring wheels enables stable and rapid walking. When encountering obstacles, the lift switches the support mode, raises the chassis, and allows the obstacle-crossing wheel set to cross the obstacle, thus solving the contradiction between high passability and high stability. Moreover, the lifting process is smooth, avoiding the transmission of vibration to the web of the wind turbine blade. Attached Figure Description

[0036] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Reference Figures 1-7 The wind turbine blade demolding vacuum adsorption and handling device with adaptive attitude adjustment includes a crossbeam 1, a left support 2 and a right support 3, and also includes a width adjustment mechanism.

[0038] The width adjustment mechanism includes:

[0039] Four pulley assemblies 4 are slidably mounted on the crossbeam 1;

[0040] Two servo steering wheels 5 are fixedly connected to the lower ends of the left bracket 2 and the right bracket 3 respectively. The servo steering wheels 5 have ±90° steering function, 0° and 90° positioning function, and also have slow (1 m / min) and fast (40 m / min) walking modes.

[0041] Mounting base 6 is fixedly connected to the lower end of crossbeam 1;

[0042] The rotating shaft 7 is rotatably connected to the inner wall of the mounting base 6;

[0043] Gear 8 is fixedly connected to the side wall of shaft 7;

[0044] Two racks 9 are fixedly connected to the side walls of the left bracket 2 and the right bracket 3 respectively, and are meshed with the gear 8;

[0045] The damage prevention component, which is mounted on the mounting base 6, is used to prevent damage to the web of the wind turbine blades when the left support 2 and the right support 3 are adjusted.

[0046] Electric hoists 38 are fixedly connected to the lower ends of both the left support 2 and the right support 3, and vacuum adsorption plates 39 are suspended from the lower ends of the electric hoists 38.

[0047] Furthermore, when transporting the wind turbine blade web, the width between the left support 2 and the right support 3 is first adjusted to facilitate the vacuum adsorption plate 39 to adsorb and transport the wind turbine blade web. By starting the servo steering wheel 5, the servo steering wheel 5 will roll on the ground, driving the left support 2 and the right support 3 to move closer to each other, thus adjusting the width between the two supports. When the left support 2 and the right support 3 move, they will synchronously drive the rack 9 to move, thereby driving the gear 8 to rotate. Due to the meshing transmission between the rack 9 and the gear 8 on both sides, the synchronous movement of the left support 2 and the right support 3 can be guaranteed.

[0048] The damage prevention component includes a sealing cavity 10 opened in the mounting base 6. A sealing plate 11 is slidably connected to the inner wall of the sealing cavity 10. Two connecting rods 12 are symmetrically fixedly connected to the lower end of the sealing plate 11. The lower ends of the two connecting rods 12 extend into the mounting base 6 and are jointly fixedly connected to a friction plate 13. Multiple springs 14 are fixedly connected between the bottom of the sealing cavity 10 and the sealing plate 11. A disk 131 is slidably embedded in the side wall of the rotating shaft 7, and the rotating shaft 7 is made of magnetic material.

[0049] The damage prevention component also includes a buffer cylinder 15 symmetrically fixedly connected to the side walls of the left support 2 and the right support 3. A sliding plate 16 is slidably connected to the inner wall of the buffer cylinder 15. A crossbar 17 is fixedly connected to the side wall of the sliding plate 16. One end of the crossbar 17 passes through the side wall of the buffer cylinder 15 and is fixedly connected to a buffer plate 18. A second spring 19 is sleeved on the side wall of the crossbar 17. The two ends of the second spring 19 are fixedly connected to the side wall of the sliding plate 16 and the inner wall of the buffer cylinder 15, respectively. The buffer cylinder 15 is connected to the sealing cavity 10 through a connecting pipe 20. Both the buffer cylinder 15 and the sealing cavity 10 are filled with hydraulic oil.

[0050] A speed sensor 21 is fixedly connected to the side wall of disk 131. The speed sensor 21 is electrically connected to the servo steering wheel 5 through a PLC control circuit.

[0051] Furthermore, the rotation of gear 8 synchronously drives the rotation of shaft 7. Due to the magnetic attraction between disk 131 and shaft 7, disk 131 will rotate synchronously with shaft 7. When left support 2 and right support 3 approach each other, buffer plate 18 will first contact the web of the wind turbine blade. Buffer plate 18 will then drive crossbar 17 to move, pushing slide plate 16 and stretching spring 19, thus providing impact cushioning and preventing damage to the web of the wind turbine blade from rigid impact. The movement of slide plate 16 will also force hydraulic oil from buffer cylinder 15 into sealing cavity 10 through connecting pipe 20, thereby pushing sealing plate 11 downwards, causing connecting rod 12 to move downwards. The friction plate 13 moves downward, making it contact the upper surface of the disk 131 and apply pressure. This causes the rotational resistance of the disk 131 to increase instantaneously, resulting in a sudden decrease in the disk 131's rotational speed. The speed sensor 21 detects this instantaneous decrease in the disk 131's rotational speed and sends a signal. This signal is then sent to the PLC control circuit to immediately stop the servo steering wheel 5, thereby halting the movement of the left support 2 and the right support 3. By using the change in the disk 131's rotational speed as a distance warning signal between the left support 2 and the right support 3, the left support 2 and the right support 3 collide with the wind turbine blade web during the width adjustment process, causing damage to the wind turbine blade web.

[0052] The pulley assembly 4 includes a mounting frame 22, an upper pulley 23, a side pulley 24, and an auxiliary pulley 25. The mounting frame 22 is slidably sleeved on the side wall of the crossbeam 1, and the lower left support 2 and the upper right support 3 of the mounting frame 22 are fixedly connected. The upper pulley 23 is rotatably connected to the inner wall of the mounting frame 22, and the upper pulley 23 rolls against the upper end of the crossbeam 1. The side pulley 24 and the auxiliary pulley 25 are both rotatably connected to the inner wall of the mounting frame 22.

[0053] A groove 26 is provided on the side wall of the crossbeam 1, and the side pulley 24 is rolled and engaged in the groove 26, and the auxiliary pulley 25 rolls and fits against the side wall of the crossbeam 1.

[0054] Furthermore, when the left support 2 and the right support 3 move, the pulley assembly 4 will slide on the crossbeam 1. At this time, the upper pulley 23, the side pulley 24 and the auxiliary pulley 25 will all roll, which can reduce the sliding resistance and make the left support 2 and the right support 3 move more smoothly.

[0055] A lubrication assembly is installed on the mounting base 6. The lubrication assembly includes an oil pump cylinder 27 fixedly connected to the lower end of the mounting base 6. A sliding plug 28 is slidably connected to the inner wall of the oil pump cylinder 27. A one-way oil inlet pipe 29 is fixedly connected to the lower end of the oil pump cylinder 27. The other end of the one-way oil inlet pipe 29 is connected to an external container storing lubricating oil. The one-way oil inlet pipe 29 only allows lubricating oil to enter the oil pump cylinder 27. The oil pump cylinder 27 is connected to the slide groove 26 through a one-way oil supply pipe 30. The one-way oil supply pipe 30 only allows lubricating oil to enter the slide groove 26 from the oil pump cylinder 27.

[0056] The lubrication assembly also includes a slider 31 that is slidably connected to the inner wall of the oil pump cylinder 27. Two vertical rods 32 are fixedly connected to the lower end of the slider 31. The lower ends of the two vertical rods 32 are fixedly connected to the slide plug 28. A reciprocating screw 33 is rotatably connected to the top of the oil pump cylinder 27. The side wall of the reciprocating screw 33 is threadedly connected to the slider 31. The lower end of the rotating shaft 7 passes through the upper end of the oil pump cylinder 27 and is fixedly connected to the reciprocating screw 33.

[0057] Furthermore, the rotation of the rotating shaft 7 will also synchronously drive the reciprocating screw 33 to rotate, thereby causing the slider 31 to slide up and down the oil pump cylinder 27. The slider 31 will drive the sliding plug 28 to slide up and down in a sealing manner through the vertical rod 32. Under the action of the sliding plug 28, the external lubricating oil will be drawn into the oil pump cylinder 27 through the one-way oil inlet pipe 29. Then, the lubricating oil in the oil pump cylinder 27 will be squeezed into the slide groove 26 through the one-way oil supply pipe 30. As a result, the side pulley 24 will be lubricated by the lubricating oil when sliding in the slide groove 26, reducing the sliding resistance and thus reducing the movement jamming of the left support 2 and the right support 3. At the same time, it can also reduce the frequency of daily maintenance.

[0058] Two spring wheels 34 are fixedly connected to the lower ends of both the left support 2 and the right support 3. A lifting platform 35 is fixedly connected to both ends of both the left support 2 and the right support 3. Electric walking wheels 36 and swivel wheels 37 are fixedly connected to the lower ends of both the left support 2 and the right support 3. The electric walking wheels 36 and swivel wheels 37 are all driven by the lifting platform 35 to lift.

[0059] Furthermore, by activating the electric hoist 38, the vacuum adsorption plate 39 is lowered. Once the vacuum adsorption plate 39 is firmly adsorbed onto the surface of the wind turbine blade web, the electric hoist 38 is activated again to pull the vacuum adsorption plate 39 upward, thereby lifting the wind turbine blade web and detaching it from the mold. Then, the servo steering wheel 5 and spring wheel 34 can be activated to move the left support 2, the right support 3, and the crossbeam 1 (at this time, the casters 37 and the electric travel wheels 36 are in the retracted state and do not touch the ground), thereby moving the adsorbed wind turbine blade web and transporting it. Because the wind turbine blade web mold has a curved layout (wide at the root and narrow at the tip), and there are obstacles such as vacuum tubes and cables below the mold, this process is challenging. Therefore, when encountering an obstacle, four lifts 35 are activated, two sets of casters 37 and electric wheels 36 descend to contact the ground, and the left support 2 and right support 3 rise, so that the height of the spring wheel 34 and servo wheel 5 is greater than the height of the obstacle. The electric wheels 36 and casters 37 are remotely controlled to drive the left support 2 and right support 3 forward (or backward). After the servo wheel 5 and spring wheel 34 cross the obstacle, the four lifts 35 are remotely controlled to rise simultaneously, so that the height of the electric wheels 36 and casters 37 is greater than the height of the obstacle. The servo wheel 5 and spring wheel 34 then drive the entire device to move, enabling the entire device to move forward (or backward) to cross the obstacle.

[0060] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
