Description

Technical Field

[0001] This utility model relates to the technical field of wind turbine generators, and in particular to a wind turbine generator tower inner cylinder reinforcement construction machine. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives a rotor to rotate and ultimately outputs alternating current. It is mainly used in coastal islands, grassland pastoral areas, mountainous areas and plateau regions that are short of water, fuel, and transportation.

[0003] Existing wind turbine tower reinforcement devices, such as the one disclosed in utility model patent application number 202121363239.7, mainly include a tower, which is placed in the middle of the reinforcement device. The shock absorption device is equipped with a spring connected to the reinforcement device, and the spring contacts the tower. In use, the baffle pushes the connecting block backward, and the connecting block applies force to the spring, which can play a certain role in shock absorption. The contact area between the baffle and the tower is large, which plays a certain role in protecting the protective layer on the surface of the tower. When other types of towers need to be reinforced, the tightening parts are loosened, the telescopic rod is adjusted to a suitable position, the tightening parts are tightened, and then the threaded rod fixedly connected to the baffle is screwed into the threaded hole until the inner arc of the baffle fits against the outer wall of the tower.

[0004] However, there is a lack of corresponding construction equipment, the space inside the tower is small, which is not conducive to the entry of large machinery, and the wind turbine towers may have different diameters, making it difficult to meet the installation requirements of towers with different diameters. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a wind turbine tower inner cylinder reinforcement construction machine that not only facilitates the movement of the reinforcing components to the inner cylinder of the tower, thus simplifying construction, but also allows the use of inner cylinders with different diameters, thereby improving the applicability of the device.

[0006] This utility model discloses a wind turbine tower inner cylinder reinforcement construction machine, including a mobile trolley; it also includes a drive mechanism, a lifting mechanism, a rotating mechanism, a support mechanism, and an adsorption mechanism. The drive mechanism is mounted on the mobile trolley, the lifting mechanism is mounted on the drive mechanism and works with the drive mechanism to lift the reinforcement component to a specified height, the rotating mechanism is mounted on the lifting mechanism and drives the reinforcement component to rotate, the support mechanism is mounted on the rotating mechanism and transports the reinforcement component to the inner wall of the tower, and the adsorption mechanism is mounted on the support mechanism and fixes the reinforcement component. The reinforcement component is placed on the rotating mechanism, and the support mechanism and adsorption mechanism work together to fix the reinforcement component. Then, the mobile trolley is moved into the tower, the drive mechanism is activated, the drive mechanism lifts the lifting mechanism and the reinforcement component to a specified height, the rotating mechanism drives the reinforcement component to a specified position, and the rotating mechanism and support mechanism bring the reinforcement component close to the inner wall of the inner cylinder, facilitating the reinforcement of the inner cylinder of the tower.

[0007] Preferably, the mobile trolley includes a body, four sets of wheels, baffles, four sets of threaded rods, and four sets of pads. The trolley body is equipped with relevant controllers and drive components. All four sets of wheels are rotatably mounted on the trolley body. The bottom end of the baffle is connected to the top end of the trolley body. All four sets of threaded rods are rotatably mounted on the bottom end of the trolley body. The four sets of pads are respectively mounted on the bottom ends of the four sets of threaded rods. The operator manipulates the trolley body to rotate and move the four sets of wheels into the wind turbine tower. Then, the trolley body drives the four sets of threaded rods to rotate, causing the four sets of pads to lift the trolley body and lift the four sets of wheels off the ground, thereby enhancing the stability of the device.

[0008] Preferably, the drive mechanism includes a servo motor, two sets of reducers, a drive shaft, two sets of guide rail boxes, two sets of bidirectional lead screws, and four sets of sliding bases. The servo motor is mounted on the baffle. The bottom ends of both sets of reducers are connected to the top of the vehicle body. The drive shaft is rotatably mounted between the two sets of reducers. The bottom ends of both sets of guide rail boxes are connected to the top of the vehicle body. The two sets of bidirectional lead screws are rotatably mounted on the two sets of guide rail boxes and connected to the two sets of reducers respectively. The four sets of sliding bases are slidably mounted on the two sets of bidirectional lead screws respectively. When the servo motor is started, it drives the reducer connected to it. The reducer drives the other set of reducers through the drive shaft. The two sets of reducers drive the two sets of bidirectional lead screws to rotate. The bidirectional lead screws drive the two sets of sliding bases to gradually approach each other.

[0009] Preferably, the lifting mechanism includes four sets of connecting rods, a scissor lift frame, two sets of sliding supports, and a base plate. The four sets of connecting rods are rotatably mounted on the four sets of sliding bases. The scissor lift frame is connected to the four sets of connecting rods. The bottom ends of the two sets of sliding supports are rotatably connected to the top ends of the scissor lift frame. The bottom ends of the base plate are slidably connected to the two sets of sliding supports. The four sets of sliding bases drive the four sets of connecting rods to move closer together, thereby causing the scissor lift frame to rise continuously. The scissor lift frame pushes the two sets of sliding supports to rise. The two sets of sliding supports move closer together and simultaneously push the base plate upward, raising the base plate to a specified height.

[0010] Preferably, the rotating mechanism includes a second servo motor, a turntable, a telescopic rod, and two sets of clamping plates. The top end of the second servo motor is connected to the bottom end of the base plate. The turntable is rotatably mounted on the base plate, and the telescopic rod is mounted on the turntable. The bottom ends of the two sets of clamping plates are connected to the top ends of the telescopic rod. The reinforcement is placed between the two sets of clamping plates and fixed in place. After the base plate is raised to the specified height, the second servo motor is started. The second servo motor drives the turntable to rotate, and the turntable drives the reinforcement to rotate to the specified position. Then the clamping plates extend to make the reinforcement contact the inner wall of the tower.

[0011] Preferably, the support mechanism includes a column, a tie plate, a hydraulic cylinder, a rib plate, and a connecting plate. The bottom end of the column is connected to the top end of the turntable. The tie plate is installed on the column and connected to the top end of the turntable. The hydraulic cylinder is installed on the column. The rib plate is installed on the hydraulic cylinder and connected to the column. The connecting plate is installed on the hydraulic cylinder, and a groove is provided inside the connecting plate. The hydraulic cylinder pushes the connecting plate, and the connecting plate pushes the adsorption mechanism to assist in fixing the reinforcement. By setting the tie plate and the rib plate, the stability of the column and the hydraulic cylinder is enhanced, allowing the reinforcement to move smoothly.

[0012] Preferably, the adsorption mechanism includes a slider, a suction cup, two sets of shock absorbers, and two sets of springs. The slider is slidably installed in the sliding groove of the connecting plate, the suction cup is installed on the slider, and both sets of shock absorbers are installed in the sliding groove of the connecting plate and connected to the top of the slider. The two sets of springs are respectively fitted onto the two sets of shock absorbers. The suction cup adsorbs the reinforcement. When the reinforcement moves to the inner wall of the tower, the bottom plate drives the clamping plate to descend. The hydraulic cylinder pushes the suction cup through the connecting plate, and the suction cup clamps the reinforcement to the inner wall. At the same time as the bottom plate descends, the connecting plate descends, thereby compressing the shock absorbers and springs, preventing the slider and reinforcement from descending, so that the reinforcement is detached from the clamping plate and fixed to the inner wall of the tower.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the reinforcement is placed on the rotating mechanism, and the support mechanism and the adsorption mechanism work together to fix the reinforcement. Then, the moving trolley is moved into the tower, the drive mechanism is started, the drive mechanism lifts the lifting mechanism and the reinforcement to the specified height, the rotating mechanism drives the reinforcement to the specified position, and the rotating mechanism and the support mechanism bring the reinforcement close to the inner wall of the inner cylinder, so that the reinforcement can reinforce the inner cylinder of the tower.

The bottom ends of the two sets of clamping plates 44 are connected to the top ends of the telescopic rod 43.During operation, the reinforcement component is first placed between two sets of clamping plates 44 to secure it. The operator then manipulates the vehicle body 11 to rotate and move the four sets of wheels 12 into the wind turbine tower. Next, the vehicle body 11 drives the four sets of threaded rods 14 to rotate, causing the four sets of pads 15 to lift the vehicle body 11, thus lifting the four sets of wheels 12 off the ground and enhancing the stability of the device.

The support mechanism 05 includes a column 51, a tie plate 52, a hydraulic cylinder 53, a rib plate 54, and a connecting plate 55. The bottom end of the column 51 is connected to the top end of the turntable 42. The tie plate 52 is installed on the column 51 and connected to the top end of the turntable 42. The hydraulic cylinder 53 is installed on the column 51. The rib plate 54 is installed on the hydraulic cylinder 53 and connected to the column 51. The connecting plate 55 is installed on the hydraulic cylinder 53, and a sliding groove is provided inside the connecting plate 55. The adsorption mechanism 06 includes a slider 61, a suction cup 62, two sets of shock absorbers 63, and two sets of springs 64. 4. The slider 61 is slidably installed in the sliding groove of the connecting plate 55. The suction cup 62 is installed on the slider 61. Both sets of shock absorbers 63 are installed in the sliding groove of the connecting plate 55 and connected to the top of the slider 61. Two sets of springs 64 are respectively fitted onto the two sets of shock absorbers 63. When it is working, the reinforcement is first placed between the two sets of clamping plates 44 to fix the reinforcement. The operator operates the vehicle body 11 to drive the four sets of wheels 12 to rotate and move into the wind power tower. Then the vehicle body 11 drives the four sets of threaded rods 14 to rotate, so that the four sets of pads 15 lift the vehicle body 11, so that the four sets of wheels 12 are off the ground, enhancing the stability of the device. The servo motor is then started. Servo motor 21 drives a connected reducer 22, which in turn drives another reducer 22 via a transmission shaft 23. The two reducers 22 drive two sets of bidirectional lead screws 25 to rotate. The bidirectional lead screws 25 cause two sets of sliding bases 26 to gradually approach each other.

The scissor lift frame 32 pushes two sets of sliding supports 33 upwards. As the two sets of sliding supports 33 approach each other, they simultaneously push the base plate 34 upwards, raising it to a specified height. Servo motor 41 is then activated, driving a turntable 42 to rotate. The turntable 42 then drives an additional... The fastener is rotated to the designated position, and then the clamping plate 44 extends to make the fastener contact the inner wall of the tower. The suction cup 62 picks up the fastener. After the fastener moves to the inner wall of the tower, the base plate 34 drives the clamping plate 44 to descend. The hydraulic cylinder 53 pushes the suction cup 62 through the connecting plate 55. The suction cup 62 clamps the fastener to the inner wall. At the same time as the base plate 34 descends, the connecting plate 55 descends, thereby compressing the shock absorber 63 and the spring 64 to prevent the slider 61 and the fastener from descending. This allows the fastener to detach from the clamping plate 44 and be fixed to the inner wall of the tower. By setting the inclined plate 52 and the rib plate 54, the stability of the column 51 and the hydraulic cylinder 53 is enhanced, allowing the fastener to move smoothly.
