TECHNICAL FIELD
[0001] The present application relates to the technical field of blade transportation, in particular to a protective wind power blade loading tool easy to assemble and disassemble. BACKGROUND
[0002] As an important part of clean energy, the development scale of wind power generation is expanding day by day. With the continuous improvement of the single machine capacity of wind turbines, the length of wind power blades has also increased significantly, and currently, super-long blades of more than 100 meters are not uncommon.
[0003] At present, the traditional transportation fixing scheme in the industry mainly relies on binding and fastening at the preset hoisting points (usually located near the root and the center of gravity) of the blade, and placing V-shaped or saddle-shaped supports under the blade to provide support; since the blade itself is a composite material thin-walled structural part with characteristics such as large volume, long length, poor rigidity, etc., the whole blade is streamline-shaped, the root part is solid, and the tip part gradually becomes light, fragile and poor in mechanical properties; during long-distance road transportation, the transportation vehicle will inevitably pass through rough and bumpy sections, and the jolting, vibration and other working conditions of the vehicle will be transmitted to the blade, causing the blade, especially the overhanging tail, to produce a large amount of up-and-down swinging and shaking, and the swinging amplitude can sometimes reach several meters; when the swinging amplitude exceeds the safety margin of the transportation support, the tail of the blade is prone to collide or rub with the ground, causing irreversible structural damage such as cracking, internal core crushing, etc., resulting in huge economic losses; if rigid binding or support is forcibly applied to the tail fragile area in order to suppress the tail swinging, the huge fastening force and local concentrated stress are easy to crush the surface skin or internal light core of the blade shell, which will also cause damage.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0017] Please refer to Figures 1-8 The present application provides a technical solution: an easily assembled and disassembled protective wind power blade shipping tool, comprising a base 1, further comprising a support frame 2, a block one 3, a locking block one 4, a block two 5, a locking block two 6, a plate 11, a supporting rod 12, a telescopic connecting rod 13, a locking unit and an adjusting unit; the support frame 2 is elastically and slidably connected with the base 1 in the vertical direction; the block one 3 is fixedly connected with the support frame 2 and is arranged in the form of an incomplete circular ring; the locking block one 4 is hingedly connected with the block one 3 and can be combined with the block one 3 to form a complete circular ring; the block two 5 is fixedly connected with the support frame 2; the locking block two 6 is hingedly connected with the block two 5 and can form a raindrop-shaped cavity after being combined with the block two 5; the plate 11 is arranged on the side of the block two 5 away from the block one 3; one end of the supporting rod 12 is fixedly connected with the plate 11, and the other end is hingedly connected with the block two 5; one end of the telescopic connecting rod 13 is hingedly connected with the supporting rod 12, and the other end is hingedly connected with a fixed plate 14 which is fixedly connected with the base 1; a spring two 15 for resetting the telescopic connecting rod 13 is sleeved on the telescopic connecting rod 13; the locking unit is arranged on the base 1 and is used for opening and closing the locking block one 4 and the locking block two 6; the adjusting unit is arranged on the side edge of the block one 3 and is used for adjusting the height of the plate 11 when the support frame 2 is inclined.
[0018] The base 1 is fixedly installed on the transport vehicle, when the wind power generation blade needs to be shipped, the blade is hoisted to the support frame 2 by the hoisting equipment, the blade root is aligned with the clamping block one 3, the cross section of the clamping block one 3 is in the shape of "U", then the hoisting equipment slowly moves the blade downward, the blade root is clamped into the inside of the clamping block one 3, at this time the middle section of the blade contacts with the clamping block two 5, the clamping block two 5 supports the middle section of the blade; then the hoisting equipment is removed, at this time the locking unit drives the locking block one 4 to rotate to close with the clamping block one 3, the clamping block two 5 closes with the locking block two 6; the clamping block one 3 cooperates with the locking block one 4 to limit the blade root, the clamping block two 5 cooperates with the locking block two 6 to fix and support the middle section of the blade; the tail end of the blade is attached to the supporting plate 11; the supporting rod 12 cooperates with the telescopic connecting rod 13 to support the supporting plate 11, the supporting plate 11 can rotate in the vertical direction within a small range, the supporting plate 11 supports the tail end of the blade; when the transport vehicle runs on the flat road, the supporting plate 11 is in the state shown in Figure 1 , at this time the tail end of the blade is in the free state, the supporting plate 11 does not apply pressure to the tail end of the blade; when the transport vehicle passes through the rugged and bumpy road section, the vehicle produces the bumpy, vibration and sharp turning conditions, the adjusting unit can drive the supporting plate 11 to lift upward through the telescopic connecting rod 13, the supporting plate 11 can drive the tail end of the blade to lift upward synchronously, avoiding the tail end of the blade to swing downward within a large range; thereby avoiding the tail end of the blade to collide with the ground, damaging the blade; when the blade is transported to the destination, the locking unit cancels the fixation of the locking block one 4 and the locking block two 6 first, then the hoisting equipment can hoist the blade upward, the locking block one 4 and the locking block two 6 can automatically open, quickly completing the hoisting work of the blade.
[0019] Specifically, as shown in Figures 1-5 , the locking unit includes the push block one 7 and the push block two 9; the push block one 7 is fixedly connected with the locking block one 4; the side of the push block one 7 is provided with the push plate one 8 which can drive it to rotate, the push plate one 8 is fixedly connected with the base 1; the push block two 9 is fixedly connected with the locking block two 6; the side of the push block two 9 is provided with the push plate two 10 which can drive it to rotate, the push plate two 10 is fixedly connected with the base 1.
[0020] When the hoisting equipment hoists the blade to the support frame 2, the hoisting equipment is removed, the support frame 2 moves downward under the gravity of the blade, since the push plate one 8 and the push plate two 10 are fixed with the base 1, the push block one 7 and the push block two 9 are respectively fixed with the locking block one 4 and the locking block two 6; therefore when the support frame 2 drives the locking block one 4 and the locking block two 6 to move downward, the push plate one 8 pushes the push block one 7, and then drives the locking block one 4 to overturn, the locking block one 4 rotates to the state shown in Figure 3 ; the push plate two 10 pushes the push block two 9, and then drives the locking block two 6 to overturn, the locking block two 6 rotates to the state shown in Figure 5The blade is heavy and the gravity center is close to the blade root, so the blade root is usually in a stable state during transportation, and the possibility of up and down shaking is small, so the fixing of the clamping block 3, the locking block 4, the clamping block 5 and the locking block 6 to the blade can be ensured by relying on the gravity of the blade; when the blade is disassembled, the blade is lifted vertically upward by the lifting equipment, and after the blade is suspended in contact with the support frame 2, the bottom elastic reset element of the support frame 2 can drive the support frame 2 to move upward, the limiting effect of the push plate 8 and the push plate 10 on the locking block 4 and the locking block 6 disappears, the resistance of the blade to move upward disappears, and the assembling and disassembling work of the blade can be quickly completed.
[0021] Specifically, as shown in Figure 1 , Figure 6 and Figure 7 , the adjusting unit comprises a sliding cylinder 18, and the sliding cylinder 18 is fixedly connected with the support frame 2; a steel ball 19 is movably installed in the sliding cylinder 18; two cylinder bodies 16 are arranged on the side of the sliding cylinder 18, and the two cylinder bodies 16 are symmetrically arranged about the sliding cylinder 18 and are slidably installed with pistons 17; the pistons 17 are located in the sliding cylinder 18 away from the cylinder bodies 16; an oil storage cylinder 22 is fixedly installed on the top of the support frame 2, and the cylinder bodies 16 are fixedly communicated with the oil storage cylinder 22 through a hose 21; the oil storage cylinder 22 is also fixedly communicated with a hose 23, and the hose 23 is fixedly connected with the telescopic connecting rod 13 away from the oil storage cylinder 22.
[0022] When the transport vehicle runs on a rugged and bumpy road section, the up and down movement of the transport vehicle head is transmitted to the end of the support frame 2 close to the vehicle head; the support frame 2 is in an inclined state, the steel ball 19 in the sliding cylinder 18 slides to one side under the action of gravity, the gravity of the steel ball 19 drives the piston 17 to slide to the inside of the cylinder body 16, the hydraulic oil in the cylinder body 16 is pressed into the hose 21, and then into the oil storage cylinder 22; the hydraulic oil in the oil storage cylinder 22 enters the telescopic connecting rod 13 through the hose 23 under the action of pressure; as shown in Figure 7 , after the hydraulic oil enters the telescopic connecting rod 13, the hydraulic oil pushes the piston rod of the telescopic connecting rod 13 to make it contract; the output end of the telescopic connecting rod 13 drives the support rod 12 and the supporting plate 11 to lift up, and the supporting plate 11 drives the tail end of the blade to lift up synchronously, preventing the tail end of the blade from shaking downward and colliding with the ground; after the transport vehicle returns to a flat road section, the spring 15 installed on the telescopic connecting rod 13 can drive the supporting plate 11 to return to the initial state, and the supporting plate 11 does not apply pressure to the tail end of the blade, only supporting action; as shown in Figure 6As shown, two cylinders 16 are provided. When the transport vehicle travels on a raised road surface, the front of the vehicle tilts upward, the slide cylinder 18 is lifted upward, and the steel ball 19 drives the right piston 17 to move inward into the cylinder 16. When the transport vehicle travels on a sunken road surface, the front of the vehicle tilts downward, the slide cylinder 18 tilts downward, and the steel ball 19 drives the left piston 17 to move inward into the cylinder 16. Therefore, when the vehicle travels on a bumpy road section, the hydraulic oil in one cylinder 16 is always forced into the telescopic connecting rod 13, thereby enabling the pallet 11 to drive the tail of the blade to lift upward.
[0023] Specifically, such as Figure 6 As shown, a limiting sleeve 20 is fixedly installed inside the cylinder body 16. The limiting sleeve 20 is used to limit the piston 17 to prevent hydraulic oil from entering another cylinder body 16 when the piston 17 moves into the cylinder body 16.
[0024] Specifically, such as Figure 6 As shown, a second spring 24 is fitted on the piston 17 for its reset; the setting of the second spring 24 can make the reset of the piston 17 and the telescopic connecting rod 13 more stable.
[0025] Specifically, such as Figure 3 As shown, a limiting block 25 is fixedly connected to the locking block 3, and a plug rod 26 that can be inserted into the limiting block 25 is slidably installed on the locking block 4. By inserting the plug rod 26 into the limiting block 25, the locking block 3 and the locking block 4 are locked together to prevent the blade root from shaking during transportation. When it is necessary to remove the blade, simply pull out the plug rod 26. The operation is simple and convenient.
[0026] Specifically, such as Figure 1 and Figure 2 As shown, a limiting slider 27 is horizontally slidably mounted on the first block 3. The limiting slider 27 is slidably connected to a second slider 29 in the vertical direction. A hydraulic cylinder 28 is fixedly connected to the second slider 29. The hydraulic cylinder 28 is fixedly connected to the base 1. After the hydraulic cylinder 28 drives the limiting slider 27 to move inward to the first block 3 through the second slider 29, the first block 3 can cooperate with the limiting slider 27 to limit the blade root.
[0027] Specifically, such as Figure 1 and Figure 8 As shown, the support frame 2 consists of a mounting plate 30, a rotating roller 31, and a spring 32; the mounting plate 30 is slidably connected to the base 1 in the vertical direction; the rotating roller 31 is rotatably connected to the mounting plate 30 and is arranged in a plurality of equidistant distributions; when the hydraulic cylinder 28 drives the blade to move and adjust the blade position, the rotating roller 31 enables the blade to move more smoothly, and the spring 32 plays the role of reset and buffer.
[0028] Specifically, such as Figure 4As shown, the support rod 12 is arranged in a telescopic structure; the length of the support rod 12 is adjustable, which can make the tail of the blade better fit the supporting plate 11.
