Description

Technical Field

[0001] This utility model relates to the field of climbing aid equipment technology, and more specifically, to a wind power operation and maintenance climbing aid. Background Technology

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source. Utilizing wind power is very environmentally friendly, and the reserves of wind energy are enormous, thus it is receiving increasing attention from countries around the world.

[0003] Wind turbines typically consist of two main parts: the tower base and the generator body. To ensure power generation efficiency, the generator body is usually located on the upper part of the tower base. When maintenance personnel need to maintain the generator body, they climb to the top of the wind turbine via a straight staircase inside the tower. With technological advancements, newly built wind turbines often have climbing aids installed on the straight staircases inside, allowing maintenance personnel to easily and quickly reach the top of the tower and complete maintenance work. While existing climbing aids have basic climbing functions, they often lack guardrails. Since the straight staircases are perpendicular to the ground from top to bottom, and wind turbine towers are generally tall, maintenance personnel cannot be adequately protected when using the climbing aids, posing a certain risk of falling. Therefore, improvements are needed. Utility Model Content

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0034] like Figures 1 to 8 As shown, this utility model provides a wind power operation and maintenance climbing aid, comprising:

[0035] Lifting platform 1, a control box 2 is fixedly installed at the rear of the top of lifting platform 1, and a fixed guardrail 3 is fixedly installed at the front of the top of lifting platform 1.

[0036] The drive mechanism is located on the outer surface of the fixed guardrail 3;

[0037] The protective mechanism is located on the left and right sides in front of the top of the lifting seat 1;

[0038] The protective mechanism includes a column 4, the bottom of which is fixedly connected to the left and right sides of the top front of the lifting seat 1. A rotating guardrail 5 is movably sleeved inside the column 4. A rotating gear 6 is fixedly sleeved on the outer surface of the rotating guardrail 5. A toothed plate 7 is meshed with the outer surface of the rotating gear 6. A fixing ring 8 is fixedly sleeved on the top of the outer surface of the column 4. A limit block 9 is fixedly installed on the top of the fixing ring 8. The outer surface of the limit block 9 is movably connected to the bottom of the toothed plate 7.

[0039] Due to the design of the two limiting blocks 9, the movement of the two toothed plates 7 will be limited. When the two toothed plates 7 move towards each other under the limitation of the two limiting blocks 9, since the two toothed plates 7 are respectively meshed with the two rotating gears 6, the two toothed plates 7 will drive the two rotating gears 6 to rotate in the opposite direction. Then, the two rotating gears 6 will drive the two rotating guardrails 5 to rotate in the opposite direction around the movable connection point with the two columns 4. When the two rotating guardrails 5 come into contact with the outer surface of the lifting seat 1 during rotation, the top of the lifting seat 1 will be in a closed state with the cooperation of the fixed guardrail 3 and the two rotating guardrails 5. At this time, the fixed guardrail 3 and the two rotating guardrails 5 will be able to protect the maintenance personnel located at the top of the lifting seat 1.

[0040] The drive mechanism includes:

[0041] The fixing sleeve 10 is fixedly connected to the outer surface of the fixing guardrail 3.

[0042] The dual-axis motor 11 has its outer surface fixedly connected to the inside of the fixed sleeve 10. The other end of the output shaft of the dual-axis motor 11 is fixedly connected to a screw 12, and the outer surface of the screw 12 is connected to the internal thread of the toothed plate 7.

[0043] When the dual-axis motor 11 is running, since the two screws 12 are threadedly connected to the two toothed plates 7 respectively, the two screws 12 will drive the two toothed plates 7 to move in opposite directions during rotation.

[0044] The lifting seat 1 has a connecting rod 13 fixedly installed on its outer surface. A fixed shaft 14 is fixedly sleeved inside the connecting rod 13. A roller 15 is movably sleeved on the outer surface of the fixed shaft 14. A stair 16 is movably connected to the outer surface of the roller 15. A reinforcing rod 17 is fixedly installed on the back of the stair 16.

[0045] The design of the rollers 15 makes the lifting seat 1 more stable when moving up and down, and the design of the reinforcing rods 17 increases the overall structural strength of the staircase 16.

[0046] The top of the staircase 16 is fixedly installed with a top plate 18, and the top of the top plate 18 is fixedly installed with a fixing block 19. The first long shaft 20 and the second long shaft 21 are respectively movably sleeved inside the fixing block 19. The two ends of the first long shaft 20 and the second long shaft 21 are fixedly sleeved with take-up rollers 22. The inside of the take-up rollers 22 is wound with steel wire 23, and the outer surface of the steel wire 23 is fixedly sleeved with the inside of the connecting rod 13.

[0047] Since the interior of the fixed block 19 is movably connected to the first long shaft 20 and the second long shaft 21 respectively, when the first long shaft 20 and the second long shaft 21 rotate around the interior of the fixed block 19, the two sets of take-up rollers 22 will rotate under the drive of the first long shaft 20 and the second long shaft 21. At this time, the two sets of take-up rollers 22 will wind the four steel wires 23, and the four steel wires 23 will pull the four connecting rods 13 as a whole, thereby causing the lifting seat 1 to move upward as a whole.

[0048] Among them, the outer surfaces of the first long shaft 20 and the second long shaft 21 are respectively fixedly sleeved with the first gear 24 and the second gear 25. The outer surface of the first gear 24 and the outer surface of the second gear 25 are meshed and connected. The outer surfaces of the first gear 24 and the second gear 25 are both fixedly connected to the outer surface of the take-up roller 22.

[0049] Since the outer surface of the second gear 25 meshes with the outer surface of the first gear 24, when the second gear 25 rotates, it will drive the first gear 24 to rotate in the opposite direction, thereby causing the first long shaft 20 to rotate in the opposite direction as a whole.

[0050] Among them, a fixing plate 26 is fixedly installed on the top of the top plate 18, a drive motor 27 is fixedly installed on the outer surface of the fixing plate 26, a rotating shaft 28 is fixedly sleeved on the other end of the output shaft of the drive motor 27, a drive gear 29 is fixedly sleeved on the other end of the rotating shaft 28, a driven gear 30 is meshed on the outer surface of the drive gear 29, and the interior of the driven gear 30 is fixedly sleeved on the outer surface of the second long shaft 21.

[0051] When the drive motor 27 is running, the rotating shaft 28 will drive the drive gear 29 to rotate. Since the outer surface of the drive gear 29 is meshed with the outer surface of the driven gear 30, when the drive gear 29 rotates, it will drive the driven gear 30 to rotate. Then the driven gear 30 will drive the second long shaft 21 to rotate as a whole. At this time, the second gear 25 will rotate under the drive of the second long shaft 21.

[0052] The top plate 18 is fixedly installed with a slide rail 31 at the bottom, and a connecting block 32 is fixedly installed on the back of the slide rail 31. The interior of the connecting block 32 is fixedly sleeved with the outer surface of the stair 16.

[0053] Due to the design of the connecting block 32, the slide rail 31 can be more firmly connected to the staircase 16.

[0054] The slide rail 31 has a slider 33 movably connected to its outer surface, a limit rod 34 movably connected inside the slider 33, and a vertical rod 35 fixedly installed on the outer surface of the limit rod 34.

[0055] Due to the design of slider 33, when maintenance personnel connect to slider 33 via a safety rope, slider 33 will cooperate with slide rail 31 to prevent maintenance personnel from falling. Due to the design of limit rod 34, the movement of the two sliders 33 will be limited.

[0056] Among them, a moving block 36 is movably sleeved on the outer surface of the vertical rod 35, the outer surface of the moving block 36 is movably connected to the inside of the slider 33, a moving block 37 is fixedly installed on the front of the moving block 36, a spring 38 is fixedly installed on the outer surface of the moving block 36, and the other end of the spring 38 is fixedly connected to the outer surface of the vertical rod 35.

[0057] Due to the design of the vertical rod 35, the movement of the two moving blocks 36 will be limited, allowing them to move only up and down. When the maintenance personnel press the two movable blocks 37, the two movable blocks 37 will drive the two moving blocks 36 to move in opposite directions. At this time, the two springs 38 will be in a compressed state. Due to the elastic force of the two springs 38, the overall movement of the two moving blocks 36 will have a good reset effect.

[0058] The moving block 36 has a first hinge block 39 fixedly installed on both the left and right sides. The first hinge block 39 has a movable rod 40 hinged inside, and the other end of the movable rod 40 has a second hinge block 41 hinged to. The outer surface of the second hinge block 41 is fixedly connected to the inside of the slider 33.

[0059] When the two moving blocks 36 move toward each other, they will drive the two sets of first hinge blocks 39 to move toward each other. Then, the two sets of first hinge blocks 39 will drive the two sets of movable rods 40 to move. Immediately afterwards, the other ends of the two sets of movable rods 40 will press the two sets of second hinge blocks 41, causing the two sets of second hinge blocks 41 to drive the two sliders 33 to move in opposite directions.

[0060] Working principle and usage process of this utility model:

[0061] When maintenance personnel climb to the top of the lifting platform 1, they start the dual-axis motor 11. At this time, the two screws 12 will rotate simultaneously. Since the outer surfaces of the two screws 12 are respectively threaded into the internal threads of the two toothed plates 7, their rotation will drive the two toothed plates 7 to move. Due to the design of the two limit blocks 9, the movement of the two toothed plates 7 will be limited. The two toothed plates 7 will then move towards each other under the limitation of the two limit blocks 9. Since the outer surfaces of the two toothed plates 7 are respectively meshed with the outer surfaces of the two rotating gears 6, when the two toothed plates 7 move towards each other... During the back movement, the two rotating gears 6 will rotate in opposite directions, and then the two rotating gears 6 will drive the two rotating guardrails 5 to rotate. At this time, the two rotating guardrails 5 will rotate in opposite directions around the movable connection point with the two columns 4. When the outer surface of the two rotating guardrails 5 comes into contact with the outer surface of the lifting seat 1 during rotation, the top of the lifting seat 1 will be in a closed state. At this time, the fixed guardrail 3 and the two rotating guardrails 5 can protect the maintenance personnel located at the top of the lifting seat 1, thereby realizing the function of improving the overall safety of the lifting seat 1 during operation.

[0062] Next, the maintenance personnel connect the safety rope to the slider 33. Due to the design of the slider 33 and the slide rail 31, the maintenance personnel are protected from falling. When the maintenance personnel need to disassemble the slider 33, they simultaneously press the two movable blocks 37. At this time, the two movable blocks 37 will drive the two moving blocks 36 to move. Due to the design of the vertical rod 35, the movement of the two moving blocks 36 is limited. The two moving blocks 36 will then move towards each other along the outer surface of the vertical rod 35 under the action of the two movable blocks 37. During this process, the two springs 38 will be compressed, and simultaneously the two moving blocks 36... The two sets of first hinge blocks 39 will be driven to move, and the two sets of first hinge blocks 39 will drive the two sets of movable rods 40 to move. The other ends of the two sets of movable rods 40 will press and push the two sets of second hinge blocks 41, so that the two sets of second hinge blocks 41 will drive the two sliders 33 to move. Due to the design of the two limiting rods 34, the movement of the two sliders 33 will be limited. At this time, the two sliders 33 will move in opposite directions along the outer surface of the two limiting rods 34. During the opposite movement, the two sliders 33 will separate from the outer surface of the slide rail 31, thus realizing the function of conveniently disassembling and assembling the sliders 33 as a whole.
