Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See Figures 1 to 4 In an embodiment of the present utility model, a wind turbine blade lifting device includes a bracket 1, a mounting bracket 9 is fixedly connected to the bottom of the bracket 1, slide rails 8 are fixedly connected to both sides of the top of the bracket 1, a sliding seat 10 is slidably connected to the slide rail 8, a mobile frame 11 is fixedly connected to the sliding seat 10, a rotating frame 12 is rotatably connected to the mobile frame 11, and a first connecting frame 13 and a second connecting frame 14 are fixedly connected to the two sets of rotating frames 12 respectively. The first connecting frame 13 and the second connecting frame 14 are embedded with each other, a bolt 27 is slidably installed in the first connecting frame 13, and a sliding installation groove 15 is provided in the second connecting frame 14, and the bolt 27 and the sliding installation groove 15 slide with each other;

[0022] The bracket 1 is fixedly connected to a fixed cylinder 3, and a first sliding telescopic rod 4 is slidably connected to the fixed cylinder 3. A bottom support plate 5 is fixedly connected to the first sliding telescopic rod 4. A first spring 6 is provided between the bottom support plate 5 and the bracket 1 and is sleeved on the first sliding telescopic rod 4.

[0023] A second sliding telescopic rod 18 is slidably connected to the mobile frame 11, one end of the second sliding telescopic rod 18 is fixedly connected to a clamping plate 19, and the other end of the second sliding telescopic rod 18 is fixedly connected to a third connecting frame 20, and a positioning cylinder 21 is fixedly connected to the third connecting frame 20, and a positioning rod 24 is fixedly connected to the third connecting frame 20, and a sliding frame 25 is slidably connected to the positioning rod 24, and a first driving cylinder 23 is fixedly connected to the sliding frame 25. A first screw 22 is rotatably connected to the mobile frame 11, and the first screw 22 passes through the positioning cylinder 21 and is threadedly connected to the first driving cylinder 23. The first screw 22 slides relative to the positioning cylinder 21. A first spring 6 sleeved on the first screw 22 is provided between the positioning cylinder 21 and the first driving cylinder 23, and a first knob 26 is fixedly connected to the first screw 22;

[0024] Drive components for driving the sliding seat 10 to move are installed on both sides of the bracket 1;

[0025] The bottom of the bracket 1 is fixedly connected to a mounting bracket 9. The utility model fixes the equipment to the transfer equipment by setting the mounting bracket 9, and then the bolts 27 are taken out from the first connecting frame 12 and the second connecting frame 12, so that the first connecting frame 12 and the second connecting frame 12 are rotated and unfolded, and then the blades are placed between the first connecting frame 12 and the second connecting frame 12 on the bottom support plate 5. At this time, the bottom support plate 5 elastically supports and fixes the blades through the setting of the first spring 6, and then the sliding seat 10 is driven to move by the driving component, and the sliding seat 10 drives the moving frame 11 to move, thereby controlling the two groups of moving frames 11 to retract and close. At this time, the moving frame 11 drives the two groups of clamping plates 19 to close each other, so that the two groups of clamping plates 19 are used to clamp the blades laterally. At the same time, the two groups of clamping plates 19 are used to drive the blades. The first screw 22 is rotated by turning the first knob 26, and the first screw 22 drives the first driving cylinder 23 to move up and down through the threaded connection with the first driving cylinder 23. The first driving cylinder 23 drives the sliding frame 25 to slide and move up and down along the positioning rod 24, and as the first driving cylinder 23 is lifted and lowered, the relative distance between the first driving cylinder 23 and the positioning cylinder 21 changes, thereby compressing the second spring 31. The compression force received by the second spring 31 is then transmitted to the clamping plate 19 through the second sliding telescopic rod 18, and then the blade is elastically clamped and fixed by the setting of the two groups of clamping plates 19. After that, the first connecting frame 13 and the second connecting frame 14 are rotated and closed, and fastened together by the bolts 27, thereby completing the elastic support and fixation of the blade.

[0026] In one embodiment of this invention, see Figures 1 to 4The first connecting frame 13 is fixedly connected to the inner wall with an engaging tooth 17, and the second connecting frame 14 is provided with an engaging groove 16 on both sides. The engaging teeth 17 and the engaging groove 16 cooperate with each other. The utility model fastens the first connecting frame 13 and the second connecting frame 14 through the setting of the engaging teeth 17 and the engaging groove 16, thereby achieving fixed clamping of the top of the blade.

[0027] In one embodiment of this invention, see Figures 1 to 4 A buffer gas rod 7 is installed at the bottom of the bracket 1, and the input end of the buffer gas rod 7 is connected to the bottom support plate 5. The utility model enhances the side weighing capacity and buffering capacity of the bottom support plate 5 through the setting of the buffer gas rod 7.

[0028] In one embodiment of this invention, see Figures 1 to 4 The driving assembly includes a fixed frame 9 fixedly connected to both sides of the bracket 1, a second driving cylinder 28 is fixedly connected to the fixed frame 9, a second screw 29 is threadedly connected to the second driving cylinder 28, one end of the second screw 29 is rotatably connected to the movable frame 11, and the other end of the second screw 29 is fixedly connected to the second knob 30. The driving assembly drives the second screw 29 to rotate by tightening the second knob 30. The second screw 29 is threadedly connected to the second driving cylinder 28, thereby converting the rotational motion of the second screw 29 into the linear motion of the second screw 29, and then driving the movable frame 11 to move through the second screw 29.

[0029] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
