Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically a lifting and hoisting device for the installation of wind power generation equipment. Background Technology

[0002] The lifting and hoisting devices for wind power equipment installation need to be adapted to high-altitude and complex environments. Their technological development focuses on intelligence, unmanned operation and green technology to meet the installation needs of onshore wind power expansion into mountainous areas.

[0003] However, existing technologies still have many defects in some similar structures when used in practice. For example, the tower, nacelle, blades and other components of wind turbines need to be connected according to the design height. Insufficient height will lead to connection errors of various components. At the same time, when there is a power failure or power outage, if the wind power generation equipment falls due to the failure of the safety mechanism, it will cause a series of serious consequences and safety accidents.

[0004] To address the aforementioned problems, the inventors have proposed a lifting and hoisting device for installing wind power generation equipment. Utility Model Content

[0005] To address the issues of inconvenience in hoisting wind power equipment to designated heights and the risk of the equipment falling during power outages or malfunctions, this invention aims to provide a lifting and hoisting device for installing wind power equipment.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a lifting and hoisting device for installing wind power generation equipment, comprising a base plate, a limiting component provided on one side of the top surface of the base plate, a lifting component fixedly connected to the top surface of the base plate, the lifting component comprising a base, two first fixing plates fixedly connected to the top of the base, one end of the opposite surfaces of the two first fixing plates being rotatably connected to a first rotating shaft, a motor fixedly connected to one end of one of the first fixing plates, the output end of the motor passing through one of the first fixing plates and fixed to one end of the first rotating shaft. The base is connected to a support frame fixedly on both sides of its top end. Two second fixing plates are fixedly connected to the upper part of one end of the support frame. The opposite ends of the two second fixing plates are rotatably connected to the inner walls of both sides of the support frame via second rotating shafts. Limiting plates are slidably connected to the inner walls of both sides of the support frame. Two connecting plates are fixedly connected to one end of the limiting plates. A hook is fixedly connected to one end of the two connecting plates. Rollers are movably sleeved on the inner walls of both sides of the hook and the outer surfaces of the two second rotating shafts. A cable is wound around the three rollers and the outer surface of the first rotating shaft.

[0007] As a preferred technical solution of this application, the limiting component includes a protective shell, one side of which is fixedly connected to one of the first fixing plates. A third rotating shaft is rotatably connected to the inner wall of one side of the protective shell. The end of the third rotating shaft extends into the first fixing plate and is fixedly connected to the first rotating shaft. A ratchet is fixedly sleeved on the outer surface of the third rotating shaft. A plurality of fourth rotating shafts arranged in a rectangular array are rotatably connected to the inner wall of one side of the protective shell. A pawl for cooperating with the ratchet is fixedly connected to the end of the fourth rotating shaft. A spring is fixedly connected to one side of the pawl. The end of the spring is fixedly connected to the inner wall of one side of the protective shell. A lever is fixedly connected to one side of the pawl.

[0008] With the above technical solution, when the first shaft rotates, the ratchet rotates with the third shaft inside the protective shell. The pawl is hinged to the inner wall of the protective shell through the fourth shaft and is pushed by a spring to engage the pawl in the ratchet tooth groove, forming a one-way lock. By moving the lever, the pawl overcomes the spring force and disengages from the ratchet, releasing the lock. After the operation is completed, the lever is released and the pawl automatically resets. When the hoisting is raised, the ratchet rotates clockwise and the pawl slides on the back of the teeth, which does not affect normal operation. If the motor fails or the power is cut off, the ratchet rotates counterclockwise due to the weight of the load, and the pawl immediately engages the tooth groove to prevent the cable from sliding down, thus preventing the wind power generation equipment from falling when there is a power failure or power outage.

[0009] As a preferred technical solution of this application, both ends of the limiting plate are fixedly connected to sliders, and the inner walls of both sides of the support frame are provided with sliding grooves. The outer surface of the slider is in contact with the inner wall of the sliding groove, and both the slider and the sliding groove are T-shaped.

[0010] Through the above technical solution, the limiting plate moves downward, causing the two sliders to slide in the inner wall of the groove respectively.

[0011] As a preferred technical solution of this application, one end of the cable is fixedly connected to a fixing frame, and the top two sides of the fixing frame are respectively fixedly connected to the bottom end of the second fixing plate.

[0012] Through the above technical solution, the bottom of the fixing frame firmly holds the cable.

[0013] As a preferred technical solution of this application, the inner walls of the three rollers are all in contact with the outer surface of the cable.

[0014] With the above technical solution, the cable slides on the outer surface of the three rollers when it is being reeled in.

[0015] As a preferred technical solution of this application, the cable is made of alloy carbon steel.

[0016] Through the above technical solutions, the cables made of alloy carbon steel are more robust.

[0017] As a preferred technical solution of this application, a groove for use with a lever is provided on one side of the protective shell.

[0018] Using the above technical solution, the lever will slide within the groove.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model can release the cable by rotating the first rotating shaft. When the cable is released, it drives three rollers to rotate in sequence. The bottom end of the fixed frame firmly holds the cable. The lower roller slowly rises, and the lower roller drives the hook to rise. The rise of the hook drives the two connecting plates to rise. The rise of the two connecting plates together drives the limit plate to rise. The rise of the limit plate drives the two sliders to rise in the inner wall of the slide groove, thereby achieving the purpose of hoisting the wind power generation equipment to the specified height.

[0021] 2. This utility model can drive the pawl to overcome the spring force and disengage from the ratchet by moving the lever, thus releasing the locked state. After the operation is completed, the lever is released and the pawl automatically resets. When the hoisting is raised, the ratchet rotates clockwise and the pawl slides on the back of the teeth, which does not affect normal operation. If the motor fails or the power is cut off, the ratchet will rotate counterclockwise due to the weight of the load, and the pawl will immediately lock into the tooth groove to prevent the cable from sliding down. This achieves the purpose of preventing the wind power generation equipment from falling when there is a power failure or power outage. Attached Figure Description

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.

[0029] Example: Figure 1-4 As shown, this utility model provides a lifting and hoisting device for installing wind power generation equipment, including a base plate 1, a limiting component 2 provided on one side of the top surface of the base plate 1, and a lifting component 3 fixedly connected to the top surface of the base plate 1.

[0030] The lifting assembly 3 includes a base 301. Two first fixing plates 302 are fixedly connected to the top of the base 301. A first rotating shaft 303 is rotatably connected to one end of the opposing surfaces of the two first fixing plates 302. A motor 304 is fixedly connected to one end of one of the first fixing plates 302. The output end of the motor 304 passes through one of the first fixing plates 302 and is fixedly connected to one end of the first rotating shaft 303. Support frames 305 are fixedly connected to both sides of the top of the base 301. Two second fixing plates 3 are fixedly connected to the upper part of one end of each support frame 305. 06. One end of the opposite face of the two second fixed plates 306 is rotatably connected to the inner walls of both sides of the support frame 305 with a second rotating shaft 307. The inner walls of both sides of the support frame 305 are slidably connected to a limit plate 308. One end of the limit plate 308 is fixedly connected to two connecting plates 309. One end of the two connecting plates 309 is fixedly connected to a hook 310. The inner walls of both sides of the hook 310 and the outer surfaces of the two second rotating shafts 307 are movably sleeved with rollers 311. The three rollers 311 and the outer surface of the first rotating shaft 303 are together wound with a cable 312.

[0031] The inner walls of the three rollers 311 are all in contact with the outer surface of the cable 312, which is made of alloy carbon steel. The two ends of the limiting plate 308 are fixedly connected to sliders 313. The inner walls of both sides of the support frame 305 are provided with grooves 314. The outer surface of the slider 313 is in contact with the inner wall of the groove 314. Both the slider 313 and the groove 314 are T-shaped. One end of the cable 312 is fixedly connected to a fixing frame 315. The top two sides of the fixing frame 315 are fixedly connected to the bottom end of the second fixing plate 306 respectively.

[0032] The two connecting plates 309 rise together, driving the limiting plate 308 to rise. The rising of the limiting plate 308 drives the two sliders 313 to rise in the inner wall of the slide groove 314, which can achieve the specified height for hoisting the wind power generation equipment.

[0033] The limiting component 2 includes a protective shell 21. One side of the protective shell 21 is fixedly connected to one of the first fixing plates 302. A third rotating shaft 22 is rotatably connected to the inner wall of one side of the protective shell 21. The end of the third rotating shaft 22 extends into the first fixing plate 302 and is fixedly connected to the first rotating shaft 303. A ratchet 23 is fixedly sleeved on the outer surface of the third rotating shaft 22. A plurality of fourth rotating shafts 24 arranged in a rectangular array are rotatably connected to the inner wall of one side of the protective shell 21. A pawl 25 for cooperating with the ratchet 23 is fixedly connected to the end of the fourth rotating shaft 24. A spring 26 is fixedly connected to one side of the pawl 25. The end of the spring 26 is fixedly connected to the inner wall of one side of the protective shell 21. A lever 27 is fixedly connected to one side of the pawl 25. A slot 28 for cooperating with the lever 27 is opened on one side of the protective shell 21.

[0034] If the motor 304 malfunctions or loses power, the ratchet 23 will rotate counterclockwise due to the weight of the load, and the pawl 25 will immediately lock into the tooth groove to prevent the cable 312 from sliding down, thus preventing the wind power generation equipment from falling when there is a power failure or power outage.

[0035] The working principle of a lifting and hoisting device for installing wind power equipment according to an embodiment of this application is as follows: First, the wind power equipment to be hoisted is transported to directly below the hook 310. When the wind power equipment needs to be hoisted, the motor 304 in the limiting device 3 is activated. The motor 304 rotates, driving the first rotating shaft 303 to rotate. The first rotating shaft 303 rotates to release the cable 312. When the cable 312 is released, it drives the three rollers 311 to rotate in sequence. The outer surface of the cable 312 slides in the inner wall of the two rollers 311. Since one end of the cable 312 is fixedly connected to the fixed frame 315, as the cable 312 is released more and more, it drives the lower hook 310 to rotate and move downward. The hook 310 drives the two connecting plates 309 to move downward. The two connecting plates 309 together drive the limiting plate 308 to move downward. The downward movement of the limiting plate 308 drives the... Two sliders 313 slide in the inner wall of the chute 314. When the hook 310 descends to the position of the wind power equipment, the hook 310 hooks the cargo, and the motor 304 is turned on again. The rotation of the motor 304 drives the first rotating shaft 303 to rotate. The first rotating shaft 303 will take in the cable 312. When taking in the cable, the cable 312 slides on the outer surface of the three rollers 311. The bottom end of the fixing frame 315 firmly holds the cable 312. The lower roller 311 slowly rises. The lower roller 311 drives the hook 310 to rise. The rise of the hook 310 drives the two connecting plates 309 to rise. The rise of the two connecting plates 309 together drives the limiting plate 308 to rise. The rise of the limiting plate 308 drives the two sliders 313 to rise in the inner wall of the chute 314, thereby achieving the purpose of hoisting the wind power equipment to the specified height.

[0036] When the first shaft 303 rotates, the ratchet 23 rotates with the third shaft 303 inside the protective shell 21. The pawl 25 is hinged to the inner wall of the protective shell 21 through the fourth shaft 24 and is pushed by the spring 26 to engage the pawl 25 in the tooth groove of the ratchet 23, forming a one-way lock. By moving the lever 27, the pawl 25 overcomes the elastic force of the spring 26 and disengages from the ratchet 23, releasing the lock. After the operation is completed, the lever 27 is released, and the pawl 25 automatically resets. When the hoisting is raised, the ratchet 23 rotates clockwise, and the pawl 25 slides on the back of the teeth, which does not affect normal operation. If the motor 304 fails or the power is cut off, the ratchet 23 rotates counterclockwise due to the weight of the load, and the pawl 25 immediately engages the tooth groove, preventing the cable 312 from sliding down. This achieves the purpose of preventing the wind power generation equipment from falling when there is a power failure or power outage.

[0037] 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.
