Description

Technical Field

[0001] This invention relates to the field of wind turbine hoisting technology, specifically to a hoisting device for wind power generation equipment. Background Technology

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Wind is a pollution-free energy source, making wind power generation very environmentally friendly, and it can generate a huge amount of electricity. Therefore, more and more countries are paying more attention to wind power generation and vigorously developing wind energy and other renewable energy sources as an important means to seize the commanding heights of future industries. The use of wind energy requires wind turbine equipment, and the installation of wind turbine equipment requires hoisting equipment to lift and install the fan blades on the top of the wind tower.

[0003] Existing hoisting equipment generally uses hoisting slings for hoisting. Due to the excessive length of the fan blades, multiple measurements are required during hoisting to find the center of gravity of the fan blades before installation. This process wastes a lot of time. Furthermore, while installers usually visually inspect the fan blades to ensure proper installation, environmental or human factors can affect the visual inspection, leading to inadequate checks and resulting in non-compliant installation and damage to the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a hoisting device for wind power generation equipment, in order to solve the problem mentioned in the background art that it is necessary to take multiple measurements to find the center of gravity of the fan blades, which may be affected by environmental or human factors, resulting in inadequate visual inspection and thus non-compliant installation of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hoisting device for wind power generation equipment, comprising: a hoisting frame,

[0018] The present invention has at least the following beneficial effects: through the tension mechanism, the tension sensor detects the tension of the steel cables on both sides, and transmits the detection data to the control device through an electrical signal. The control device starts the first electric rod on the corresponding side of the steel cable. The first electric rod pushes the first extension plate to extend outward, thereby fine-tuning the center of gravity between the hoisting equipment and the fan blade. If the tension of the steel cables at both ends is still different when the first extension plate moves to the maximum position, the control device will drive the fixed motor of the corresponding steel cable. The fixed motor drives the placement roller to rotate, retracting and tightening the steel cable so that the tension of all steel cables is exactly the same.

[0019] With the protective mechanism in place, the weight of the fan blades is distributed to the air duct through the bolts during installation. Once the fan blades are fully installed, the hoisting equipment will no longer be subjected to the weight of the fan blades. If, after the fan blades are installed, the moving rod does not return to the corresponding slot and contact the electrode plate, it indicates that the fan blades are not installed correctly. In this case, contact between the electrode plate and the electrode plate will cause the corresponding indicator light to flash, thus reminding the installer of the fan blade installation status.

The bumper 20 can protect the fan blades, thereby reducing the probability of damage to the fan blades.

[0044] The following is a further introduction to the specific working method, as detailed below: Specifically, when the hoisting equipment for wind power generation is in operation / use: the fan blades are placed on the hanger 1, the upper and lower clamps 212 are activated to bring them into contact with the fan blades, and the hoisting equipment is moved upwards. The tension sensor 205, which is attached to the surface of the steel cable 204, detects the tension of the steel cables 204 on both sides and transmits the detection data to the control device 14 via an electrical signal. The control device 14 then controls the first electric motor on the corresponding side of the steel cable 204. When the lever 213 is activated, the first electric lever 213 pushes the first extension plate 214 to extend outward, thereby fine-tuning the center of gravity between the hoisting equipment and the fan blades and reducing the problem of tipping over due to misalignment of the center of gravity. If the tension of the steel cables 204 at both ends is still different when the first extension plate 214 moves to the maximum position, the control device 14 will drive the fixed motor 208 of the corresponding steel cable 204. The fixed motor 208 drives the placement roller 207 to rotate, thereby retracting and tightening the steel cable 204 so that the tension of all steel cables 204 is exactly the same.

[0045] Once the hoisting equipment and the fan blade's center of gravity are stable, the fan blade is lifted upwards. The fan blade will compress the lower clamping plate 212. As the lower clamping plate 212 moves downwards, it will compress the airbag 301, forcing the air inside the airbag 301 into the air collection tank 303 through the inflation pipe 302. The air entering the air collection tank 303 pushes the sliding rod 304 inside the air collection tank 303, thereby moving the moving part 306 and the electrode plate 308. After the fan blade is installed, the fan blade's own weight will be distributed through the bolts to... On the air duct, the hoisting equipment will no longer be subjected to the weight of the fan blades. At this time, the spring steel is no longer under force and the clamping plate 212 will reset. The airbag 301, which is no longer compressed, will no longer squeeze the gas inside. The fixed spring 305, which is no longer compressed, will drive the moving rod 304 to reset inside the gas collection tank 303. The moving rod 304 will drive the moving part 306 and the electrode plate 307 to move. When the gas inside the gas collection tank 303 returns to the airbag 301 through the inflation pipe 302, the electrode plate 307 will not contact the electrode plate 308.

[0046] If the moving rod 304 does not return to the corresponding slot and contact the electrode plate 308 after the fan blade is installed, it means that the lower clamping plate 212 is still under the pressure of the fan blade. It is very likely that the fan blade was not installed properly. At this time, the contact between the electrode plate 307 and the corresponding electrode plate 308 will cause the corresponding indicator light 309 to flash, thereby reminding the installer of the installation status of the fan blade.

[0047] All of the above electronic devices are powered by internal batteries (not shown) or external wires (not shown).
