[0002] During the maintenance of wind turbine towers, which are usually quite tall, maintenance personnel need to be transported to the top of the tower using internal climbing equipment to carry out maintenance work. Current maintenance equipment, such as non-climbing devices, is mostly driven by traction, which does not allow for proper monitoring of the personnel's condition and poses some safety risks.

[0003] A search revealed Chinese patent application CN202211564125.8, which discloses a non-climbing device, including a non-climbing device body and a foot pedal. The edge of the foot pedal or the edge of the non-climbing device body is provided with a first connecting member for detachable connection to a toolbox. The patent also discloses a toolbox, including a toolbox body, with a second connecting member on the edge of the toolbox body for detachable connection to the non-climbing device body or the foot pedal. The patent further discloses a connection structure between the non-climbing device and the toolbox, including the aforementioned non-climbing device and the aforementioned toolbox. The largest side of the toolbox contacts the upper surface of the foot pedal in the non-climbing device and rests on the foot pedal. The first connecting member on the edge of the foot pedal or the edge of the non-climbing device body is detachably connected to the second connecting member on the edge of the toolbox body. The non-climbing device in the above-mentioned document has the following shortcomings: although it can meet certain usage requirements, it cannot effectively monitor the specific situation of personnel and needs further improvement. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a climbing device for the maintenance of wind power generation equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A climbing device for maintaining wind power equipment includes a climbing frame body, which is installed inside the wind power tower via a fixing frame. A climbing mechanism is mounted on the climbing frame body, and the climbing mechanism includes:

[0007] The slide rail is fixed to the main body of the climbing frame;

[0008] The slide block is slidably connected to the outer wall of the slide rail, and connecting brackets are fixed on both sides of the slide block.

[0009] The traction drive assembly is based on a steel wire rope connected to a connecting frame and is used to drive the slide to move up and down.

[0010] The upright frame is fixed to the outer wall of one side of the slide block, and a lifting platform is fixed to the bottom of one side of the upright frame.

[0011] The slide block has a mounting base fixed to one side of its outer wall, sleeves fixed to both ends of the mounting base, end seats fixed to both ends of the sleeves, and a rotating wheel rotatably mounted on the outer side of the end seat. An annular rubber sleeve is fixed to the outer wall of the rotating wheel. A friction strip is fixed on the main body of the climbing frame, and the rotating wheel with the annular rubber sleeve rolls on the surface of the friction strip.

[0012] The inner side of the rotating wheel is provided with protruding teeth, and the end side wall of the sleeve is slidably connected with a toothed seat. The toothed seat is connected to the sleeve through a first spring. One end of the toothed seat is equipped with a one-way toothed seat through a built-in spring. The one-way toothed seat and the protruding teeth cooperate to form a one-way limiting structure. The inner side of the rotating wheel is provided with a groove. The one-way toothed seat does not initially contact the protruding teeth.

[0013] The mounting base is equipped with a control rod, which has two symmetrical second protrusions. A sliding column is slidably connected inside the sleeve. One end of the sliding column has a first protrusion, and the other end of the first protrusion has a guide post. The guide post is initially located between the two tooth seats. An arc-shaped wedge is fixed to the other end of the sliding column. The arc-shaped wedge is connected to the inner wall of the sleeve by a third spring and is initially located between the two second protrusions. When the control rod moves up and down, the second protrusions press the sliding column to both sides, and then the first protrusions press the tooth seats and one-way teeth outward, so that the one-way teeth are located on the movement path of the protrusions, or even locked into the slots.

[0014] The mounting base is equipped with a position detection component and an alarm component for detecting the position of the control lever. The position detection component and the alarm component are connected to the same control system as the traction drive component. When the control lever deviates from the initial position by a set distance, the control system controls the traction drive component to stop working and the alarm component will sound an alarm.

[0015] The control rod is connected to the protective assembly via a connecting rope.

[0016] As a preferred embodiment of the present invention: a pulley is installed on the top of the upright frame via a pulley bracket, a guide frame is fixed on the top of the upright frame, the top of the guide frame has a ring structure, and the inner side of the ring structure of the guide frame is an arc surface, and the connecting rope is connected to the protective component after passing through the pulley and the guide frame.

[0017] As a preferred embodiment of the present invention, the protective component includes:

[0018] The straps have a safety rope attached to one side.

[0019] The hook is fixed to one end of the safety rope, and the safety rope is detachably connected to one end of the connecting rope through the hook.

[0020] As a preferred embodiment of the present invention, the strap is provided with an adjusting buckle for adjusting the tightness.

[0021] As a preferred embodiment of the present invention: the upright frame is fixed with handles on both sides, the handles are L-shaped, and a control button is provided at the top of the handles, the control button being connected to the control system of the traction drive assembly.

[0022] As a preferred embodiment of the present invention, the outer side of the grip is provided with an anti-slip sleeve.

[0023] As a preferred embodiment of the present invention: arc-shaped plates are fixed on both sides of the upright frame, and arc-shaped baffles are slidably connected inside the arc-shaped plates, and fixing components for fixing the arc-shaped baffles are provided on the arc-shaped plates.

[0024] As a preferred embodiment of the present invention, the fixing component includes:

[0025] The fixing pin has multiple pin holes on the arc-shaped stop, and the fixing pin is slidably connected to the inner wall of the arc-shaped plate. The fixing pin is compatible with the arc-shaped stop.

[0026] The second spring has one end fixed to the top of the arc-shaped plate and the other end fixed to the top of the fixing pin.

[0027] Pull ring, the pull ring is fixed to the outer wall of the top of the fixing pin.

[0028] As a preferred embodiment of the present invention: the upper and lower sides of the fixing frame are provided with evenly distributed mounting plates, a protective rope is provided between the two fixing frames, and the two ends of the protective rope are provided with protective rope fixing parts, and the protective rope is installed on the mounting plate through the protective rope fixing parts.

[0029] As a preferred embodiment of the present invention, the protective rope fixing part includes:

[0030] Sleeve, the sleeve is mounted on the mounting plate;

[0031] The slide tube is movably installed inside the sleeve;

[0032] The slide rod is located inside the slide cylinder. One end of the slide rod is equipped with a spherical head, the diameter of which is smaller than the inner diameter of the sleeve. A protective rope is fixed to one end of the slide rod.

[0033] The elastic claw has one end fixed to one end of the slide tube. Multiple elastic claws are arranged in a circular pattern. The middle part of the elastic claw has an arc-shaped structure. The multiple elastic claws have a cage-like structure. One end of the elastic claw is provided with a guide part. The guide parts of the multiple elastic claws cooperate to form a trumpet-shaped structure. When the elastic claw is not deformed, the size of its cage-like structure is smaller than the inner diameter of the sleeve. When the spherical head is inserted into the middle of the elastic claw, the elastic claw expands outward and cannot pass through the sleeve.

[0034] There is sufficient friction between the sleeve and the slide, which is greater than the resistance of the spherical head when it is inserted into the elastic claw.

[0035] The beneficial effects of this invention are as follows:

[0036] 1. This invention, by setting up a climbing mechanism, enables the traction drive assembly to work, driving the slide to rise, and then transporting maintenance personnel via a lifting platform. During the transport process, when the maintenance personnel's position deviates, the protective assembly pulls the control rod. As the control rod moves up and down, the second protrusion squeezes the slide column to both sides, and the first protrusion squeezes the locking tooth seat and one-way locking tooth outward. If the deviation is small, the one-way locking tooth extends into the movement path of the protrusion tooth, which will not obstruct the upward rolling of the wheel. The warning assembly alarms, prompting the personnel to adjust their position in time. When the maintenance personnel's position deviates too much, and the control rod is pulled a large distance, the control system controls the traction drive assembly to stop working based on the detection component. As the one-way locking tooth extends outward, it engages in the locking groove during the rotation of the wheel, preventing the wheel from continuing to rotate. Based on the friction between the wheel and the friction strip, a braking effect is achieved. This invention has high reliability and strong practicality.

[0037] 2. By setting pulleys and guide frames, the present invention can guide the connecting rope to avoid structural jamming and improve reliability; by setting grip handles, control buttons and other structures, the working state of the traction drive component can be controlled by the control buttons, thereby facilitating the control of the slide lifting and lowering and improving reliability.

[0038] 3. By setting up structures such as arc-shaped baffles, the present invention can adjust the position of the arc-shaped baffles on the outside of the lifting platform and fix them with fixing pins. During transportation, the arc-shaped baffles provide protection, thereby improving safety.

[0039] 4. By setting up a protective rope and a protective rope fixing part, the present invention can provide effective protection on the outside of the lifting platform. When the protective rope is pulled, the ball head first gets stuck in the middle of the elastic claw, the elastic claw expands, causing the slide cylinder to be unable to get out of the sleeve. When disassembly is required, the ball head is pushed out of the elastic claw by the slide rod and the slide cylinder is pulled out of the sleeve, thus achieving convenient disassembly.

Detailed Implementation

[0049] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0050] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0051] Example 1:

[0052] A climbing device for maintaining wind power equipment, such as Figure 1-8 As shown, the system includes a climbing frame body 1, which is installed inside the wind turbine tower via a fixing frame 3. A climbing mechanism is mounted on the climbing frame body 1, and the climbing mechanism includes:

[0053] Slide rail 6, slide rail 6 is fixed on the main body 1 of the climbing frame;

[0054] Slide 32 is slidably connected to the outer wall of slide rail 6, and connecting brackets 11 are fixed on both sides of slide 32;

[0055] The traction drive assembly (not shown in the figure) is connected to the connecting frame 11 based on the wire rope 12 and is used to drive the slide 32 to move up and down.

[0056] The upright frame 10 is fixed to the outer wall of one side of the slide block 32, and a lifting platform 5 is fixed to the bottom of one side of the upright frame 10.

[0057] The slide block 32 has a mounting base 30 fixed on one side of its outer wall, and sleeves 31 fixed at both ends of the mounting base 30. End seats 27 are fixed at both ends of the sleeves 31. A rotating wheel 39 is rotatably mounted on the outer side of the end seat 27. An annular rubber sleeve 29 is fixed on the outer wall of the rotating wheel 39. A friction strip 7 is fixed on the climbing frame body 1, and the rotating wheel 39 with the annular rubber sleeve 29 rolls on the surface of the friction strip 7.

[0058] The inner side of the rotating wheel 39 is integrally provided with a tooth 40, and the end side wall of the sleeve 31 is slidably connected with a tooth seat 43. The tooth seat 43 is connected to the sleeve 31 through a first spring 44. One end of the tooth seat 43 is equipped with a one-way tooth 42 through a built-in spring. The one-way tooth 42 and the tooth 40 cooperate to form a one-way limiting structure. The inner side of the rotating wheel 39 is provided with a groove 41. The one-way tooth 42 does not initially contact the tooth 40.

[0059] The mounting base 30 is provided with a control rod 16, which has two symmetrical second protrusions 34. A sliding column 36 is slidably connected inside the sleeve 31. One end of the sliding column 36 is provided with a first protrusion 37, and one end of the first protrusion 37 is provided with a guide post 38. The guide post 38 is initially located between two tooth seats 43. An arc-shaped wedge 33 is fixed to the other end of the sliding column 36. The arc-shaped wedge 33 is connected to the inner wall of the sleeve 31 by a third spring 35 and is initially located between the two second protrusions 34. When the control rod 16 moves up and down, the second protrusions 34 press the sliding column 36 to both sides, and then the first protrusions 37 press the tooth seats 43 and the one-way tooth 42 outward, so that the one-way tooth 42 is located on the moving path of the protrusion 40, or even inserted into the slot 41.

[0060] The mounting base 30 is equipped with a position detection component and an alarm component for detecting the position of the control lever 16. The position detection component and the alarm component are connected to the same control system as the traction drive component. When the control lever 16 deviates from the initial position by a set distance, the control system controls the traction drive component to stop working and the alarm component will sound an alarm.

[0061] The control rod 16 is connected to the protective component via a connecting rope 28, and the protective component is worn on the human body;

[0062] By setting up a climbing mechanism, the traction drive component can work to drive the slide 32 to rise, and then transport maintenance personnel through the lifting platform 5. During the transport process, when the position of the maintenance personnel deviates, the control rod 16 is pulled based on the protective component. When the control rod 16 moves up and down, the second protrusion 34 presses the slide column 36 to both sides, and then the first protrusion 37 presses the tooth seat 43 and the one-way tooth 42 outward. If the deviation is not much, the one-way tooth 42 extends into the movement path of the protrusion 40. At this time, it will not obstruct the upward rolling of the wheel 39. The warning component alarms to remind the personnel to adjust their position in time.

[0063] When the position of the maintenance personnel deviates too much, or when the control lever 16 is pulled and moved a large distance, the control system controls the traction drive component to stop working based on the detection of the detection component. As the one-way tooth 42 extends outward, it is locked into the slot 41 during the rotation of the wheel 39, preventing the wheel 39 from continuing to rotate. Based on the friction between the wheel 39 and the friction strip 7, the braking effect is achieved. It has high reliability and strong practicality.

[0064] The detection component can be a ranging sensor, etc., and is not limited in this embodiment.

[0065] To improve reliability; such as Figure 4 As shown, the top of the upright frame 10 is equipped with a pulley 17 via a pulley bracket, and a guide frame 18 is fixed to the top of the upright frame 10. The top of the guide frame 18 has a ring structure, and the inner side of the ring structure of the guide frame 18 is an arc surface. The connecting rope 28 is connected to the protective component via the pulley 17 and the guide frame 18.

[0066] By setting pulley 17 and guide frame 18, the connecting rope 28 can be guided to avoid structural jamming and improve reliability.

[0067] To improve reliability; such as Figure 3 As shown, the protective component includes:

[0068] Strap 8, with a safety rope 25 attached to one side of strap 8;

[0069] Hook 19 is fixed to one end of safety rope 25, and safety rope 25 is detachably connected to one end of connecting rope 28 via hook 19.

[0070] To improve practicality; such as Figure 3 As shown, the strap 8 is provided with an adjustment buckle 15 for adjusting the tightness.

[0071] For ease of controlling lifting; such as Figure 4As shown, the upright frame 10 is fixed with handles 22 on both sides. The handles 22 are L-shaped and a control button 20 is provided at the top of the handles 22. The control button 20 is connected to the control system of the traction drive assembly.

[0072] By setting up structures such as the handle 22 and the control button 20, the working state of the traction drive component can be controlled through the control button 20, thereby facilitating the control of the lifting and lowering of the slide 32 and improving reliability.

[0073] To improve practicality; such as Figure 4 As shown, an anti-slip sleeve 21 is provided on the outer side of the handle 22.

[0074] To improve the protective effect; such as Figure 3 , Figure 4 As shown, arc-shaped plates 9 are fixed on both sides of the upright frame 10, and arc-shaped baffles 14 are slidably connected inside the arc-shaped plates 9. Fixing components for fixing the arc-shaped baffles 14 are provided on the arc-shaped plates 9.

[0075] To facilitate fixing the curved baffle 14; such as Figure 3 , Figure 4 As shown, the fixing component includes:

[0076] The fixing pin 26 is provided with multiple pin holes 24 on the arc-shaped stop 14. The fixing pin 26 is slidably connected to the inner wall of the arc-shaped plate 9 and is adapted to the arc-shaped stop 14.

[0077] The second spring 23 has one end fixed to the top of the arc plate 9 and the other end fixed to the top of the fixing pin 26.

[0078] Pull ring 13, the pull ring 13 is fixed to the outer wall of the top end of the fixing pin 26;

[0079] By setting up structures such as the arc-shaped baffle 14, the position of the arc-shaped baffle 14 on the outside of the lifting platform 5 can be adjusted and fixed by the fixing pin 26. During transportation, the arc-shaped baffle 14 is used for protection, which improves safety.

[0080] Example 2:

[0081] A climbing device for maintaining wind power equipment, such as Figure 1-8 As shown, in order to improve the protective effect, this embodiment makes the following improvements based on embodiment 1: the upper and lower sides of the fixing frame 3 are provided with evenly distributed mounting plates 4, the two fixing frames 3 are provided with a protective rope 2, the two ends of the protective rope 2 are provided with protective rope fixing parts, and the protective rope 2 is installed on the mounting plate 4 through the protective rope fixing parts.

[0082] For ease of disassembly and assembly; such as Figure 8 As shown, the protective rope fixing part includes:

[0083] Sleeve 46, sleeve 46 is mounted on mounting plate 4;

[0084] The slide is movably installed inside the sleeve 46;

[0085] The slide rod 45 is located inside the slide cylinder. One end of the slide rod 45 is integrally provided with a spherical head 47. The diameter of the spherical head 47 is smaller than the inner diameter of the sleeve 46. The protective rope 2 is fixed to one end of the slide rod 45.

[0086] The elastic claw 49 is fixed at one end to one end of the slide cylinder. Multiple elastic claws 49 are arranged in a circular pattern. The middle part of the elastic claw 49 has an arc-shaped structure. The multiple elastic claws 49 have a cage-like structure. One end of the elastic claw 49 is integrally provided with a guide part 48. The guide parts 48 of the multiple elastic claws 49 cooperate to form a trumpet-shaped structure. When the elastic claw 49 is not deformed, the size of its cage-like structure is smaller than the inner diameter of the sleeve 46. When the spherical head 47 is inserted into the middle of the elastic claw 49, the elastic claw 49 expands outward and cannot pass through the sleeve 46.

[0087] There is sufficient friction between the sleeve 46 and the slide, which is greater than the resistance of the spherical head 47 when it is engaged in the elastic claw 49;

[0088] By setting up the protective rope 2 and the protective rope fixing part, effective protection can be provided on the outside of the lifting platform 5. When the protective rope 2 is pulled, the ball head 47 first gets into the middle of the elastic claw 49, the elastic claw 49 expands, causing the slide cylinder to be unable to get out of the sleeve 46. When disassembly is required, the ball head 47 is pushed out of the elastic claw 49 by the slide rod 45, and the slide cylinder is pulled out of the sleeve 46, so that disassembly can be easily achieved.

[0089] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
