Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1-7 As shown, this utility model provides a wind power equipment maintenance and repair platform, including a base plate 1, with four base plates 1 in close contact on their sides; protective components 2 are provided on both sides of the upper surface of the four base plates 1 to protect maintenance personnel; two mounting columns 3 can be detachably installed on one side of the upper surface of the four base plates 1 to store the protective net 32; two fixing columns 4 can be detachably installed on the side of the upper surface of the four base plates 1 away from the mounting columns 3 to limit the movement of the protective net 32. The protective net 32 ​​covers the gaps in the guardrail, preventing maintenance personnel's tools from falling through the gaps in the guardrail; a winding rod 31 is rotatably installed inside the mounting column 3; the protective net 32 ​​is fixedly installed on the outer surface of the winding rod 31; an installation strip 33 is fixedly installed on the end of the protective net 32 ​​away from the winding rod 31, and the end of the installation strip 33 away from the winding rod 31 is movably inserted into the fixed column 4.

[0022] The protective component 2 includes a movable base 201, which is slidably disposed inside the base plate 1. Four movable bases 201 and two movable bases 201 are slidably installed on both sides of the base plate 1, respectively. Two connecting bars 202 are rotatably installed on both sides of the movable base 201. A horizontal plate 203 is rotatably connected to the end of the connecting bar 202 away from the movable base 201. The lower surface of the horizontal plate 203 is in contact with the upper surface of the base plate 1 to drive the horizontal plate 203 to move. In use, the movement of the movable base 201 drives the connecting bar 202 to swing, and the swing of the connecting bar 202 drives the horizontal plate 203 to move, so that the horizontal plate 203 moves upward.

[0023] By adopting the above technical solution, the movable seat 201 can drive the horizontal plate 203 to move.

[0024] Two bidirectional screws 14 are rotatably installed on one side of the base plate 1, and both ends of the bidirectional screws 14 are threadedly connected to a movable seat 201. Two drive screws 13 are rotatably installed on the side of the base plate 1 away from the bidirectional screws 14, and the movable seat 201 is threadedly connected to the drive screws 13 to drive the movable seat 201 to move. In use, the movable seat 201 is moved by the rotation of the bidirectional screws 14 and the drive screws 13.

[0025] By adopting the above technical solution, the bidirectional screw 14 and the drive screw 13 can drive the moving seat 201 to move.

[0026] Two opposing bidirectional screws 14 and drive screws 13 are each fixedly mounted with a first bevel gear 15 at their closest ends. A drive rod 16 is rotatably mounted in the middle of the four base plates 1. A second bevel gear 17 is fixedly mounted at both ends of the drive rod 16, and the second bevel gear 17 meshes with the first bevel gear 15 to drive the bidirectional screws 14 and drive screws 13 to rotate. In use, rotating the drive rod 16 drives the second bevel gear 17 to rotate, which in turn drives the first bevel gear 15 to rotate, which in turn drives either the bidirectional screw 14 or the drive screw 13 to rotate.

[0027] By adopting the above technical solution, the drive rod 16 can drive the bidirectional screw 14 and the drive screw 13 to rotate.

[0028] Both ends of the take-up rod 31 are fixedly installed with a No. 1 spring 34, and the end of the No. 1 spring 34 away from the take-up rod 31 is fixedly connected to the inside of the mounting column 3 to drive the take-up rod 31 to rotate. When in use, when the No. 1 spring 34 releases the deformation force, the take-up rod 31 is driven to rotate through the No. 1 spring 34.

[0029] By adopting the above technical solution, the No. 1 spring 34 can drive the winding rod 31 to rotate.

[0030] A trapezoidal block 45 is slidably installed inside the top of the fixed column 4, and the bottom end of the trapezoidal block 45 is movably locked inside the mounting strip 33. A second spring 46 is fixedly installed on the upper surface of the trapezoidal block 45, and the top end of the second spring 46 is fixedly connected inside the fixed column 4. A pull rod 47 is fixedly installed on the upper surface of the trapezoidal block 45, and the top end of the pull rod 47 moves through the interior of the fixed column 4 to limit the mounting strip 33. In use, when the bottom end of the trapezoidal block 45 is locked inside the mounting strip 33, the mounting strip 33 is limited by the trapezoidal block 45, and the trapezoidal block 45 can be moved by the pull rod 47 to disengage from the interior of the mounting strip 33.

[0031] By adopting the above technical solution, the trapezoidal block 45 can drive the mounting strip 33 to be limited.

[0032] A fixing screw 43 is movably inserted into the side of the fixing post 4, and one end of the fixing screw 43 movably passes through the fixing post 4 and the mounting strip 33. An octagonal nut 44 is threaded to one end of the fixing screw 43, and the side of the octagonal nut 44 is in contact with the fixing post 4 to limit the mounting strip 33. In use, the fixing screw 43 is inserted so that one end of the fixing screw 43 passes through the fixing post 4 and the mounting strip 33. At this time, the octagonal nut 44 is screwed on so that the side of the octagonal nut 44 is in contact with the fixing post 4 to limit the mounting strip 33.

[0033] By adopting the above technical solution, the fixing screw 43 and the octagonal nut 44 can limit the installation strip 33.

[0034] Both mounting post 3 and fixing post 4 have two mounting screws 41 fixedly installed on their lower surfaces. The bottom end of the mounting screw 41 movably penetrates the base plate 1. The bottom end of the mounting screw 41 is threadedly connected to a fixing nut 42, and the upper surface of the fixing nut 42 is in contact with the lower surface of the base plate 1. This is used to install the mounting post 3 and fixing post 4. In use, the bottom end of the mounting screw 41 is made to penetrate the base plate 1. Then, the fixing nut 42 is screwed on, so that the upper surface of the fixing nut 42 contacts the lower surface of the base plate 1, thus completing the installation of the mounting post 3 or fixing post 4.

[0035] By adopting the above technical solution, the mounting screw 41 and the fixing nut 42 can realize the installation of the mounting post 3 and the fixing post 4.

[0036] Limiting screws 204 are movably inserted into both sides of the horizontal plate 203. One end of the limiting screw 204 movably passes through the horizontal plate 203 and the mounting post 3 or the fixing post 4. One end of the limiting screw 204 is threadedly connected to a limiting nut 205, and the side of the limiting nut 205 is in movable contact with the side of the horizontal plate 203. This is used to realize the assembly between the mounting post 3 and the fixing post 4 and the horizontal plate 203. In use, the tops of the mounting post 3 and the fixing post 4 are inserted into the horizontal plate 203. At this time, the limiting screw 204 is inserted, so that one end of the limiting screw 204 passes through the horizontal plate 203 and the mounting post 3 or the fixing post 4. Then, the limiting nut 205 is tightened, so that the side of the limiting nut 205 contacts the horizontal plate 203, thus completing the assembly between the mounting post 3 and the fixing post 4 and the horizontal plate 203.

[0037] By adopting the above technical solution, the limiting screw 204 and the limiting nut 205 can realize the assembly between the mounting column 3 and the fixing column 4 and the horizontal plate 203.

[0038] Several long screws 11 are movably inserted into both sides of the base plate 1 on the right side. The far end of the long screw 11 moves through the other two base plates 1 on the same side. One end of the long screw 11 is threaded with a mounting nut 12, and the mounting nut 12 is in contact with the base plate 1 to realize the splicing between the base plates 1. In use, the four base plates 1 are spliced ​​together. At this time, the long screw 11 is inserted so that the long screw 11 passes through three base plates 1. Then the mounting nut 12 is screwed on so that the side of the mounting nut 12 contacts the base plate 1, thus completing the splicing between the base plates 1.

[0039] By adopting the above technical solution, the long screw 11 and the mounting nut 12 can be spliced ​​together between the base plate 1.

[0040] Working principle: First, the mounting screws 41 on the lower surface of the mounting column 3 and the fixing column 4 are inserted through the base plate 1. Then, the fixing nut 42 is tightened so that the upper surface of the fixing nut 42 contacts the lower surface of the base plate 1, thus completing the installation of the mounting column 3 and the fixing column 4 with the base plate 1. Next, rotating the drive rod 16 drives the second bevel gear 17 to rotate. The rotation of the second bevel gear 17 drives the first bevel gear 15 to rotate. The rotation of the first bevel gear 15 drives the bidirectional screw 14 or the drive screw 13 to rotate. The rotation of the bidirectional screw 14 and the drive screw 13 drives the moving seat 201 to move. The movement of the moving seat 201 drives the connecting bar 202 to swing. The swing of the connecting bar 202 drives the horizontal plate 203 to move, causing the horizontal plate 203 to move upward. At this time, the connecting bar 202 and the horizontal plate 203 form a guardrail to protect the maintenance personnel. The limit screw 204 is positioned at both ends of the horizontal plate 203, so that one end of the limit screw 204 passes through the horizontal plate 203 and the mounting post 3 or the fixing post 4. At this time, the limit nut 205 is tightened so that the side of the limit nut 205 contacts the horizontal plate 203, completing the assembly between the mounting post 3 and the fixing post 4 and the horizontal plate 203. Then, pull the mounting strip 33. The movement of the mounting strip 33 drives the protective net 32 ​​to move, which covers the gaps in the guardrail. One end of the mounting strip 33 is inserted into the fixed post 4. When the mounting strip 33 and the trapezoidal block 45 come into contact, the trapezoidal block 45 is pushed upward. When the trapezoidal block 45 and the slot of the mounting strip 33 correspond, the second spring 46 releases the deformation force, pushing the trapezoidal block 45 downward and inserting it into the slot, thus limiting the mounting strip 33. Then, insert the fixing screw 43, so that one end of the fixing screw 43 passes through the fixed post 4 and the mounting strip 33. Then, tighten the octagonal nut 44, so that the side of the octagonal nut 44 comes into contact with the fixed post 4, thus completing the limitation of the mounting strip 33. Finally, bring the four base plates 1 together so that their sides are close to each other, insert the long screw 11 so that the long screw 11 passes through the three base plates 1, and then tighten the mounting nut 12 so that the side of the mounting nut 12 contacts the base plate 1, thus completing the splicing between the base plates 1.

[0041] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
