Description

Technical Field

[0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy. Wind is a pollution-free energy source. Using wind power to generate electricity is very environmentally friendly and can generate huge amounts of electricity. Therefore, more and more countries pay more attention to wind power generation and vigorously develop wind energy and other renewable energy as an important means to seize the commanding heights of future industries. The use of wind energy requires wind power equipment, and the installation of wind power equipment requires hoisting equipment. The hoisting equipment needs to lift the fan blades to the top of the wind tower.

The middle part of the bottom of the three-connected plate 19 is fixedly connected with an anti-collision rod 20. The three-connected plate 19 can fix the position of the anti-collision rod 20. The movement of the three-connected plate 19 can drive the anti-collision rod 20 to move. The anti-collision rod 20 can protect the fan blades, thereby reducing the probability of damage to the fan blades.

[0044] The following is a further introduction in conjunction with the specific working method, as described below: Specifically, when the hoisting device for wind power generation equipment is working / in use: the fan blade is placed on the hanger 1, the upper and lower clamping plates 212 are started, so that the upper and lower clamping plates 212 are in contact with the fan blade, and the hoisting device is moved upward. The tension sensor 205 connected to the surface of the steel cable 204 will detect the tension of the steel cables 204 on both sides, and the detection data will be transmitted to the control device 14 through an electrical signal, and the control device 14 will control the first electric motor on the corresponding side of the steel cable 204. The rod 213 is started, and the first electric rod 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 to reduce the rollover problem caused by the wrong 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 corresponding to the steel cable 204, and the fixed motor 208 drives the placement roller 207 to rotate, so as to retract and tighten the steel cable 204, so that the tension of all the steel cables 204 is exactly the same;

[0045] When the center of gravity of the lifting equipment and the fan blades is stable, the fan blades are lifted upward, and the fan blades will squeeze the lower clamping plate 212. When the lower clamping plate 212 moves downward, it will squeeze the airbag 301, and the air inside the airbag 301 will enter the air collecting tank 303 through the inflation tube 302. The air entering the air collecting tank 303 pushes the moving rod 304 sliding inside the air collecting tank 303, so that the moving part 306 and the electrode plate 308 move. After the fan blades are installed, the weight of the fan blades themselves will be dispersed to On the wind tube, the hoisting equipment will no longer be affected by the gravity of the fan blades. At this time, the spring steel is no longer subjected to the force to drive the lower clamping plate 212 to reset. The air bag 301 that has lost its compression will no longer squeeze the gas inside. The fixed spring 305 that has lost its squeezing force drives the moving rod 304 to reset inside the gas collecting tank 303. The moving rod 304 drives the moving part 306 and the electrode sheet 307 to move. When the gas inside the gas collecting tank 303 returns to the inside of the air bag 301 through the inflation tube 302, the electrode sheet 307 will not contact the electrode plate 308.

[0046] If the moving rod 304 does not return to the corresponding empty slot and contact the electrode plate 308 after the fan blades are installed, it means that the lower clamping plate 212 is still under the pressure of the fan blades. It is very likely that the fan blades are not installed properly. At this time, the electrode sheet 307 contacts the corresponding electrode plate 308, causing the corresponding signal light 309 to flash, thereby reminding the installation master of the installation status of the fan blades.

[0047] The above electronic devices are all powered by internal batteries (not shown) or external wires (not shown).
