[0002] With the rapid development of wind power generation technology, the height of wind turbine towers is constantly increasing. Maintenance personnel need to safely and efficiently reach designated locations inside the tower to carry out maintenance work using climb-free equipment. Climb-free equipment is a key personnel-carrying device.

[0003] In actual operation scenarios, maintenance personnel need to manually deploy the pedals before starting the climber and manually retract them after the operation is completed. For example, when the climber descends unloaded or returns to its initial position, if the pedals are not retracted in time, their protruding parts may interfere with the cover plates, cable supports, or other structures on the inner wall of the tower as the climber moves. Although the operation manual clearly requires maintenance personnel to check the status of the pedals, in high-frequency and high-intensity operation environments, manual operation is prone to oversights due to fatigue, distraction, or confusion of operation priorities. In addition, the narrow space and insufficient lighting inside the tower further increase the risk of human error. Utility Model Content

[0030] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0031] Reference Figures 1-10 This embodiment provides an automatically opening and closing fan climbing device pedal, including a pedal body 100; and,

[0032] The flipping assembly 200 includes a crank 201 and a short rod 202 disposed on one side of the crank 201; wherein,

[0033] When the pedal body 100 is subjected to force and rotates, the crank 201 will rotate accordingly. When the pedal body 100 is no longer subjected to force, the crank 201 will push the pedal body 100 back to its original position.

[0034] The outer wall of the pedal body 100 is connected to a moving component 300. The moving component 300 includes a housing 301 and a first rotating shaft 302 disposed on one side of the housing 301. The housing 301 is the main body of the non-climbing device, and various devices for realizing the non-climbing device function are installed inside it.

[0035] There are two first rotating shafts 302, which are respectively set on the bottom sides of the housing 301. The first rotating shafts 302 are connected to the housing 301 by welding.

[0036] The outer wall of the pedal body 100 is provided with a connecting assembly 400. The connecting assembly 400 includes a support rod 401 and a connecting sleeve 402 disposed on one side of the support rod 401. The pedal body 100, the support rod 401 and the connecting sleeve 402 are all connected to each other by welding.

[0037] The outer wall of the crank 201 is connected to the bottom of the pedal body 100. The outer wall of the short rod 202 is provided with a limiting sleeve 203. The outer wall of the limiting sleeve 203 is rotatably connected to the end of the first rotating shaft 302. A nut 204 is connected to one side of the limiting sleeve 203. A first elastic element 205 is connected to the outer wall of the nut 204. The end of the first elastic element 205 is connected to the inner wall of the first rotating shaft 302. When the pedal body 100 is rotated, the crank 201 will rotate with the pedal body 100. When the worker stands on the pedal body 100, it will press down on the pedal body 100 and the crank 201. When the worker leaves the pedal body 100, the first elastic element 205 will drive the short rod 202 to rotate. At this time, the pedal body 100 and the crank 201 will rotate 90 degrees, so that the pedal body 100 rotates to fit against the housing 301.

[0038] The first elastic element 205 uses a torsion spring.

[0039] A baffle 303 is provided on the outer wall of the housing 301. The outer wall of the first rotating shaft 302 is rotatably connected to the outer wall of the connecting sleeve 402. When the pedal body 100 rotates to be perpendicular to the housing 301, the baffle 303 will abut against the support rod 401, so that the support rod 401 cannot continue to rotate.

[0040] A handle 304 is provided on one side of the housing 301, a button 305 is provided on the top of the housing 301, and a remote lever 306 is provided on the outer wall of the housing 301 at a position parallel to the button 305. When using the climbing device, after the worker stands on the pedal body 100, he needs to hold the handle 304 and press the button 305 to start the climbing device, so that the climbing device can lift or lower the worker.

[0041] Other safety features can be installed on the non-climbing device to ensure worker safety.

[0042] As an alternative embodiment, this embodiment provides another flipping mechanism, which can also provide sufficient support for the pedal body 100, thereby increasing the load-bearing limit of the climb-free device.

[0043] The outer wall of the housing 301 is provided with a limiting groove 501. A second rotating shaft 502 is slidably connected to the inner wall of the limiting groove 501. A first sleeve 503 is rotatably connected to the outer wall of the second rotating shaft 502. A receiving tube 504 is provided on the outer wall of the first sleeve 503. An extension rod 505 is slidably connected to the inner wall of the receiving tube 504. A second sleeve 506 is provided on one side of the extension rod 505. A third rotating shaft 507 is rotatably connected to the inner wall of the second sleeve 506. The outer wall of the third rotating shaft 507 is connected to the bottom of the pedal body 100. When the pedal body 100 rotates, it will pull the third rotating shaft 507 forward. As the pedal body 100 moves, the third rotating shaft 507 will drive the second rotating shaft 502, the first sleeve 503, the storage tube 504, and the extension rod 505 to move. The second rotating shaft 502 will move downward within the limiting groove 501. When the second rotating shaft 502 moves to the bottom, the extension rod 505 will be gradually pulled out of the storage tube 504 until the pedal body 100 is fully extended. The storage tube 504 and the extension rod 505 will hold the pedal body 100, providing a certain support force for the pedal body 100. At the same time, they can also block the two sides of the pedal body 100 to provide safety for the non-climbing device.

[0044] The inner wall of the storage tube 504 is provided with a sliding channel 508. One end of the extension rod 505 is located in the sliding channel 508, and a second elastic element 509 is sleeved on one side of the extension rod 505 in the sliding channel 508. When no one is standing on the pedal body 100, the second elastic element 509 will push the extension rod 505, causing the extension rod 505 to move towards the top of the sliding channel 508. At this time, the pedal body 100 will gradually retract. When it is retracted to a certain extent, the second rotating shaft 502 will slide upward towards the limiting groove 501 until the pedal body 100 is in contact with the housing 301.

[0045] The second elastic element 509 uses a high-pressure spring.

[0046] As an optional embodiment, this embodiment provides another flipping mechanism, which can save more space, reduce additional load, reduce the weight of the non-climbing device, and make it easier for the power components of the non-climbing device to move the non-climbing device, thereby extending its service life.

[0047] A first gear 601 is provided on the outer wall of the first rotating shaft 302. A second gear 602 meshes with the outer wall of the first gear 601. A limit rod 603 is connected to the inner wall of the second gear 602. The limit rod 603 is connected to the outer wall of the housing 301. When the pedal body 100 rotates, the first gear 601 will drive the second gear 602 to rotate and move by an angle. When the pedal body 100 rotates to a position perpendicular to the housing 301, it will be stopped by the baffle 303 and then stop moving.

[0048] The second gear 602 has a placement groove 604 on the side near the housing 301. The limiting rod 603 is connected to the outer wall and a push plate 605 is provided. The outer wall of the push plate 605 is provided with a third elastic member 606. The third elastic member 606 is connected to the inner wall of the placement groove 604. When there is no one on the pedal body 100, the third elastic member 606 will push the second gear 602 to rotate, which will then cause the first gear 601 to rotate, thus driving the pedal body 100 to fit against the outer wall of the housing 301.

[0049] The third elastic element 606 is a spring with an arc.

[0050] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
