Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade hoisting technology, specifically a wind turbine blade hoisting and adjustment device. Background Technology

[0002] Wind turbine blades are the core components of wind turbines, converting natural wind energy into electrical energy. They are also a primary indicator of a wind turbine's design and technological level. Supporting infrastructure includes power collection lines, turbine foundations, on-site roads, and intelligent monitoring systems, and are constructed concurrently with the photovoltaic project.

[0003] With the completion of photovoltaic construction, the narrow construction area for wind power projects and the limited equipment transportation channels increase the difficulty of scheduling. In the project area, there are an average of 25-30 days of strong winds in spring (March-May), with gusts reaching 10-14.6 m / s, far exceeding the conventional wind speed limit for wind turbine hoisting (≤6 m / s). Strong winds can easily cause the crane boom to sway and components to swing and deviate, which not only affects the installation accuracy (tower verticality deviation ≤1‰) but may also collide with surrounding photovoltaic facilities. Furthermore, sandstorms can reduce the braking sensitivity of the equipment, further increasing the construction risk. To address these issues, we have proposed a wind turbine blade hoisting adjustment device. Utility Model Content

[0004] The purpose of this utility model is to provide a wind turbine blade hoisting and adjustment device to solve the problem mentioned in the background art that strong winds can easily cause the crane boom to sway and the components to swing and deviate, which not only affects the installation accuracy but may also collide with surrounding photovoltaic facilities, further increasing the construction risk.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind turbine blade hoisting and adjustment device, comprising a hoisting device connected to the top of a tower, a fixing frame connected to the bottom of the hoisting device, a clamping mechanism installed inside the fixing frame, a wind turbine blade being clamped inside the clamping mechanism, an electronic level and an inclination sensor installed inside the fixing frame, a correction mechanism provided on the outside of the fixing frame, and a balancing mechanism provided inside the fixing frame.

[0006] Preferably, the correction mechanism includes hooks, a servo motor, a winding reel, and a windproof cable. Hooks are connected to the four corners of the fixing frame, and a windproof cable is connected to the outside of the hooks. The other end of the windproof cable is connected to a winding reel, which is mounted on the servo motor. The servo motor is located on the outside of the crane tower.

[0007] Preferably, the balancing mechanism includes an electric telescopic rod, a connecting frame, and a counterweight. The electric telescopic rod is symmetrically installed inside the fixed frame, the output end of the electric telescopic rod is connected to the connecting frame, and the counterweight is provided on the outside of the connecting frame.

[0008] Preferably, the servo motor is mounted on the drive vehicle, and a track is provided on the outside of the crane tower, with the drive vehicle mounted on the track.

[0009] Preferably, a screw is fixedly connected to the center of the connecting frame, a limit ring is threaded to the outer side of the screw, and the counterweight is movably sleeved on the screw.

[0010] Preferably, the fixing frame has a sliding groove inside, and the inner diameter of the sliding groove is adapted to the connecting frame and the counterweight.

[0011] Preferably, the electronic level is fixedly installed at the center of the mounting frame, and the output end of the electronic level is located on both sides of the mounting frame.

[0012] Preferably, the tilt sensor is fixedly installed at the four corners of the mounting bracket, and the tilt sensor is located on the outside of the slide groove.

[0013] Preferably, the hooks are provided in eight sets and are symmetrically installed at the four corners of the fixing frame.

[0014] Preferably, the electronic level and tilt sensor are electrically connected and share data information with the servo motor.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a correction mechanism, addresses the tilting of the fixed frame caused by swaying in strong winds. The internal electronic level and tilt sensor detect the tilt of the four corners of the fixed frame. Based on the tilt of the four corners, the corresponding servo motor is activated to pull the windproof cable to correct the fixed frame. Furthermore, under the restraint of the windproof cable, the position of the servo motor is adjusted by the drive vehicle, which limits the range of motion of the wind turbine blades, preventing them from swaying and colliding with surrounding photovoltaic facilities, thus improving the protective effect.

[0016] 2. By setting up a balancing mechanism, this utility model can achieve the balancing effect when the lifting point does not coincide with the center of gravity of the wind turbine blade. The position of the counterweight can be changed after lifting, so that the lifting device can move in the air without other force points, thereby enabling the blade to adjust autonomously when aligning with the hole and improving the blade installation efficiency.

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.

[0021] Please see Figure 1-5 The present invention provides an embodiment of a wind turbine blade hoisting and adjustment device, comprising a hoisting device 2 connected to the top of a pylon 1, a fixing frame 3 connected to the bottom of the hoisting device 2, a clamping mechanism 4 installed inside the fixing frame 3, a wind turbine blade 5 clamped inside the clamping mechanism 4, an electronic level 6 and an inclination sensor 7 installed inside the fixing frame 3, the electronic level 6 being a VLM series horizontal tilt angle sensor, the inclination sensor 7 being a VL E5S high precision level, a correction mechanism 8 provided on the outside of the fixing frame 3, and a balancing mechanism 9 provided inside the fixing frame 3; This device, through its internal electronic level 6 and tilt sensor 7, along with the correction mechanism 8 and balancing mechanism 9, solves the problem that strong winds can easily cause the crane boom to sway and components to swing and shift, which not only affects installation accuracy but may also collide with surrounding photovoltaic facilities, further increasing construction risks.

[0022] Furthermore, the calibration mechanism 8 includes hooks 801, a servo motor 802, a winding reel 803, and a windproof cable 804. Hooks 801 are connected to the four corners of the fixing frame 3. The windproof cable 804 is connected to the outer side of the hooks 801, and the other end of the windproof cable 804 is connected to the winding reel 803. The winding reel 803 is mounted on the servo motor 802, which is located on the outer side of the crane tower 1. Figure 3 As shown, this structure is used to activate the corresponding servo motor 802 when one corner of the fixed frame 3 is tilted, which drives the winding wheel 803 to rotate, so that the windproof cable 804 is wound around the surface of the winding wheel 803 and pulled. At the same time, several other servo motors 802 perform a cable release operation on the windproof cable 804, thereby correcting the tilt angle of the fixed frame 3.

[0023] Furthermore, the balancing mechanism 9 includes an electric telescopic rod 901, a connecting frame 903, and a counterweight 904. The electric telescopic rod 901 is symmetrically installed inside the fixed frame 3. The output end of the electric telescopic rod 901 is connected to the connecting frame 903, and the counterweight 904 is provided on the outer side of the connecting frame 903. For example... Figure 4 As shown, this structure is used to activate the corresponding electric telescopic rod 901 based on the data information detected by the electronic level 6 and the balancing mechanism 9, thereby driving the connecting frame 903 and the counterweight 904 to move to the corresponding position and make the fixed frame 3 reach the balance point.

[0024] Furthermore, each set of servo motors 802 can be individually mounted on a set of drive vehicles 806, and a track 805 is provided on the outside of the crane tower 1, with the drive vehicle 806 mounted on the track 805. For example... Figure 5 As shown, this structure is used to adjust the position of the windproof cable 804 by moving the drive vehicle 806 along the track 805, thereby controlling the range of motion of the fixing frame 3.

[0025] Furthermore, a screw 905 is fixedly connected to the center of the connecting bracket 903, and a limit ring 906 is threadedly connected to the outer side of the screw 905. A counterweight 904 is movably sleeved on the screw 905. Figure 4 As shown, this structure is used to connect to the screw 905 via a limit ring 906, making it convenient to add or remove the counterweight 904.

[0026] Furthermore, the fixing frame 3 has a sliding groove 902 inside, and the inner diameter of the sliding groove 902 is adapted to the connecting frame 903 and the counterweight 904. Figure 4 As shown, this structure is used to allow the connecting frame 903 and the counterweight 904 to move stably within the sliding groove 902 through the setting of the sliding groove 902.

[0027] Furthermore, the electronic level 6 is fixedly installed at the center of the mounting bracket 3, with the output ends of the electronic level 6 located on both sides of the mounting bracket 3. For example... Figure 4 As shown, this structure is used to inspect both sides of the fixture 3 by using an electronic level 6 located at the center.

[0028] Furthermore, the tilt sensor 7 is fixedly installed at the four corners of the mounting bracket 3, and the tilt sensor 7 is located on the outside of the slide groove 902. For example... Figure 4 As shown, this structure is used to detect the tilt of the four corners of the fixing frame 3 using the tilt sensor 7.

[0029] Furthermore, eight sets of hooks 801 are provided and symmetrically installed at the four corners of the fixing frame 3. For example... Figure 3 As shown, this structure is used to connect to the four corners of the fixed frame 3 via eight sets of hooks 801, which makes it convenient to connect different hooks 801 according to different positions and make adjustments.

[0030] Furthermore, the electronic level 6 and the tilt sensor 7 are electrically connected and share data information with the servo motor 802. For example... Figure 3 As shown, this structure is used to electrically connect to the servo motor 802 via the electronic level 6 and the tilt sensor 7, and to synchronize data information with the servo motor 802 for easy calibration.

[0031] Working principle: When using, such as Figure 1 As shown, move the crane 1 to the designated position, activate the clamping mechanism 4 to clamp the wind turbine blade 5, and simultaneously, as... Figure 3 and Figure 5 As shown, according to the installation location, the windproof cable 804 is connected to the corresponding hook 801, and the drive vehicle 806 is started. The drive vehicle 806 moves along the track 805 to adjust the position of the windproof cable 804, thereby controlling the range of motion of the fixing frame 3. Figure 1 and Figure 3 As shown, the crane 1 is started for lifting and lowering. During the lifting and lowering process, the internal electronic level 6 and tilt sensor 7 detect the tilt of the two sides and four corners of the fixed frame 3, and synchronize the data information with the servo motor 802. When one corner of the fixed frame 3 tilts, the corresponding servo motor 802 is activated, driving the winding wheel 803 to rotate, so that the windproof cable 804 is wound around the surface of the winding wheel 803, pulling the windproof cable 804. At the same time, several other sets of servo motors 802 perform the windproof cable 804 unwinding operation, thereby correcting the tilt angle of the fixed frame 3. Meanwhile, as... Figure 4 As shown, starting the corresponding electric telescopic rod 901 drives the connecting frame 903 and the counterweight 904 to move to the corresponding position, so that the fixed frame 3 reaches the balance point. The above is the complete working principle of this utility model.
