[0026] 1. The camshaft is connected to the support frame of the second frame by means of the guide rail, and the guide rail is provided with a plurality of connecting rods and a plurality of connecting rods, wherein the plurality of connecting rods have the plurality of connecting rods and a plurality of connecting rods. DETAILED DESCRIPTION

[0027] The following is combined with Figure 1-9 This application is described in further detail.

[0028] Please refer to Figure 1 and Figure 3The support frame 1 is provided with a plurality of support members 3, and the support members 3 are connected to each other by a plurality of connecting members 3. The support members 3 are connected to the support frame 1 and the support member 1 are connected to the support frame 1.

[0029] Specifically, first, the connecting component 3 can be used to adapt and adjust according to the length of the placed wind turbine blade. Then, after the wind turbine blade is placed, the pressure-adjusting rod 4 is operated to keep the first-level bearing seat 5 completely in contact with the surface of the wind turbine blade. During the adjustment process, the hinged rod 6 can assist in supporting the clamping seat 7. After fitting, the outer side of the wind turbine blade is continued to be clamped and fixed through the clamping component 8 to prevent it from moving in the longitudinal direction. When it needs to be moved later, the rolling component 9 can be used to assist in the movement.

[0030] See Figure 1 and Figure 7 , a secondary bearing seat 51 is commonly provided on the two clamping seats 7 on the primary bearing seat 5, and the secondary bearing seat 51 is rotatably connected to one of the clamping seats 7 through an ear plate and a pin shaft, and a locking assembly 10 is connected between the secondary bearing seat 51 and the other clamping seat 7; a rubber pad is also provided on the bearing surface of the secondary bearing seat 51, and two limiting grooves are also provided through the interior of the secondary bearing seat 51, and the two limiting grooves inside the secondary bearing seat 51 are also commonly provided with a clamping assembly 8 for clamping and fixing the generator blades supported inside; the secondary bearing seat 51 is provided to support multiple wind turbine blades in a stacked manner at the same time, and the use of longitudinal stacking can save floor space, and by setting the secondary bearing seat 51 in a flippable manner, it can effectively avoid affecting the access of the wind turbine blades on the primary bearing seat 5.

[0031] See Figure 1 and Figure 4The pressure-regulating rod 4 includes an upper fixing rod 41 fixedly arranged at the center position of the lower end of the first-level bearing seat 5, the middle outer wall of the upper fixing rod 41 is provided with an annular protrusion, and the outer wall of the upper fixing rod 41 is movably sleeved with a threaded sleeve 42, the upper end of the threaded sleeve 42 is located above the annular protrusion, and the lower end of the threaded sleeve 42 is threadedly connected to the lower fixing rod 43. The upper and lower fixing rods 41 and the lower fixing rods 43 are provided with a mounting groove 44 at the opposite ends. A pressure-regulating spring is connected together in the two opposite mounting grooves 44, and the pressure-regulating spring is located inside the threaded sleeve 42; the outer wall of the threaded sleeve 42 is fixedly provided with an adjusting cylinder 45 perpendicular to its own axis; when the wind turbine blade is placed on the surface of the first-level bearing seat 5 or the second-level bearing seat 51 and cannot be fully fitted, the external rod can be inserted into the interior of the adjusting cylinder 45 to drive the threaded sleeve 42 to rotate, so that the threaded sleeve 42 drives the upper fixing rod 41 to move up, thereby controlling the first-level bearing seat 5 or the second-level bearing seat 51 to rise and fit the outer wall of the wind turbine blade.

[0032] See Figure 8 The inner side wall of the limit groove is provided with a guide groove 511, and the clamping assembly 8 includes two inverted L-shaped clamping parts 81 symmetrically arranged inside the guide groove 511. The side of the inverted L-shaped clamping part 81 that is in contact with the wind turbine blade is provided with a rubber layer. The opposite ends of the two inverted L-shaped clamping parts 81 are both wedge surfaces, and rollers 82 are provided through the inside of the inverted L-shaped clamping parts 81, and the rollers 82 are rollingly arranged in the guide groove 511. The guide groove 511 includes an arc segment and two transverse segments connected to the arc segment.

[0033] See Figure 3 The vertical sections of the two inverted L-shaped clamping parts 81 inside the same guide groove 511 are commonly penetrated by a rectangular frame 83, and the two rectangular frames 83 corresponding to the same first-level bearing seat 5 are opened on the opposite sides with movable through grooves, and two cross bars 84 are slidingly arranged inside the movable through grooves, and both ends of the cross bars 84 are slidingly connected to the vertical sections of the adjacent inverted L-shaped clamping parts 81; an operating screw rod 85 is commonly threadedly connected between the two cross bars 84, and the operating screw rod 85 is provided with a bidirectional thread.

[0034] When the wind turbine blade is placed on the primary support seat 5 or the secondary support seat 51, it can be fixed on both sides by the clamping assembly 8 to prevent it from moving longitudinally. Specifically, after the wind turbine blade is fixed on the primary support seat 5 or the secondary support seat 51, the operating screw 85 is operated to rotate. During the rotation, the two cross bars 84 approach each other, further driving the inverted L-shaped clamping parts 81 to approach each other. During the process of the inverted L-shaped clamping parts 81 approaching each other, they will move along the arc section of the guide groove 511. , so that the inverted L-shaped clamping piece 81 gradually moves downward to clamp and fix the side wall of the wind turbine blade; the purpose of providing the horizontal section connected to the arc section on the guide groove 511 is to allow the inverted L-shaped clamping piece 81 to be completely retracted into the guide groove 511 before placing the wind turbine blade, so as to avoid interference with the placement of the wind turbine blade. After the placement is completed, the horizontal section of the inverted L-shaped clamping piece 81 can first extend out of the guide groove 511 during the process of approaching, so that it can be clamped and fixed to the outer wall of the wind turbine blade later.

[0035] See Figure 3 、 Figure 5 and Figure 9 The rolling assembly 9 includes a scissor arm 91 hingedly arranged in the mounting groove, and the lower end of the scissor arm 91 is slidably connected to a rolling member 92. The inside of the scissor arm 91 is threadedly connected to a threaded adjustment rod 93 through a connecting block. The connecting block is slidably connected to the scissor arm 91, and the threaded adjustment rod 93 is rotatably arranged on the No. 1 base 1 and the No. 2 base 2; by operating the threaded adjustment rod 93 to rotate, the rolling member 92 can be controlled to extend or retract into the mounting groove, thereby controlling whether the position transfer of the wind turbine blade can be completed by pushing the bracket.

[0036] See Figure 2 and Figure 6The connecting assembly 3 includes two fixed blocks 31 respectively connected to the opposite surfaces of the No. 1 base 1 and the No. 2 base 2, and the inner wall of the fixed block 31 is provided with a limit rod 32, and a movable block 33 is slidably provided on the outer wall of the limit rod 32, and the outer surface of the limit rod 32 is symmetrically sleeved with a limit spring, and the part connected between the movable block 33 and the limit rod 32 is located between the two limit springs; the external thread of the movable block 33 is connected to a connecting rod 34, and a bidirectional threaded sleeve 35 is connected between the two connecting rods 34; when it is necessary to support wind turbine blades of different lengths through the present invention, the number of connecting rods 34 can be increased to achieve this; the purpose of movably arranging the movable block 33 inside the fixed block 31 in the present invention is to facilitate the operation of rotating the threaded adjustment rod 93 to control the rolling element 92 to extend or retract into the mounting groove, and the up and down displacement during adjustment is supplemented by the relative movement between the movable block 33 and the fixed block 31, so as to avoid damage to the wind turbine blade caused by the displacement when the rolling element 92 is extended or retracted into the mounting groove when the wind turbine blade is carried on the present invention.

[0037] See Figure 1 、 Figure 7 and Figure 8 The lock assembly 10 includes a guide rod 101, and locking blocks 102 are slidingly sleeved at both ends of the guide rod 101. A tightening spring is sleeved on the outer wall of the middle part of the guide rod 101, and the two ends of the tightening spring respectively abut against the locking blocks 102; the outer wall of the secondary bearing seat 51 and the outer wall of one of the card seats 7 are both provided with locking grooves that cooperate with the locking blocks 102; one end surface of the locking block 102 that cooperates with the locking groove is a concave and convex rectangular tooth structure to increase the friction between the locking block 102 and the locking groove and improve the locking strength. The tightening spring is used to pull the two locking blocks 102 against each other and clamp them in the locking groove, and cooperate with the concave and convex structure to increase the friction.

[0038] After placing the wind turbine blades on the primary support seat 5, when continuing to place the wind turbine blades on the secondary support seat 51, first rotate the secondary support seat 51 to a horizontal state, and then fix it through the locking assembly 10. When fixing, pull the two locking blocks 102 respectively and snap them into the two locking grooves; the locking assembly 10 can effectively ensure the stability of the secondary support seat 51, and it is also convenient to flip the secondary support seat 51 to take out the wind turbine blades placed on the primary support seat 5 later.
