[0003] For existing large wind turbines, generally, the wind power tower is first cast, and then assembled at a designated location. Since wind turbines are generally installed in locations with sufficient wind energy, when installing the wind power tower and the wind turbine blades, the wind energy will also affect the installation process. For example, when the wind power tower is lifted to a high altitude, the crane generally only holds the upper part of the wind power tower, and the wind will blow the wind power tower, causing the lower part of the wind power tower to shake, which in turn leads to the inability to cooperate between the wind power towers, resulting in low installation efficiency of the wind power tower.

Specific Embodiments

[0024] The following further describes the present invention in detail in conjunction with the drawings and specific embodiments, but does not limit the protection scope and application scope of the present invention.

[0025] The 1st Embodiment

[0026] A modular installation device for a wind power tower barrel, according to Figures 1 - 6 shown, includes a first module 1; a plurality of first modules 1 are sequentially connected to each other to form an annular structure, all the first modules 1 are integrally distributed in an annular array, and each first module 1 is internally provided with a rechargeable battery;

[0027] It further includes an adapter 2, a second module 3, a moving component, and a winding component; each first module 1 is rotatably connected to an adapter 2; a torsion spring is provided between each adapter 2 and the corresponding first module 1; a second module 3 is fixedly connected to the upper part of each adapter 2; a moving component is connected to each of the first module 1 and the second module 3; a winding component is connected between every two adjacent first modules 1; a winding component is also connected between every two adjacent second modules 3.

[0028] The moving component includes an electric actuator 7, an electric walking wheel 8, and an electric telescopic support leg 9; several electric actuators 7 are respectively installed on each first module 1 and the second module 3; the electric actuator 7 is an electric push rod; an electric walking wheel 8 is installed on the telescopic part of each electric actuator 7; an electric telescopic support leg 9 is installed on each electric walking wheel 8.

[0029] All the electric actuators 7 on the same first module 1 are integrally distributed in a "pin" shape to maintain the stability of the first module 1 during walking.

[0030] The winding component includes a first motor 10, a wire wheel 11, and a steel cable 12; among every two adjacent first modules 1, one of the first modules 1 is installed with the first motor 10 and the wire wheel 11, and a fixed wheel 111 is installed on the other first module 1; among every two adjacent second modules 3, the first motor 10 and the wire wheel 11 are jointly installed on one of the second modules 3, and the fixed wheel 111 is installed on the other second module 3; the output shaft of the first motor 10 is connected to the wire wheel 11, and a steel cable 12 is wound around the wire wheel 11 and the fixed wheel 111.

[0031] The fixed wheel 111 to which the fixed end of the steel cable 12 is fixedly connected is detachably connected to the corresponding first module 1 and the second module 3.

[0032] The working steps of the above embodiment are as follows:

[0033] First, the external crane lifts the bottom lower tower barrel 001 and fixes it on the preset pile foundation. At this time, the assembly of this equipment can be carried out. Arrange the first modules 1 in a circular ring around the lower tower barrel 001, and fix the fixed wheels 111 with steel cables 12 on the corresponding first modules 1 and second modules 3 through bolts. Thus, the first modules 1, second modules 3, steel cables 12 and the corresponding components form a circular ring surrounding the outside of the lower tower barrel 001, and make the electric walking wheels 8 and electric telescopic supports 9 both contact the lower tower barrel 001. Then, control all the electric actuators 7 to extend, synchronously driving the corresponding electric walking wheels 8 and electric telescopic supports 9 to move towards the direction close to the lower tower barrel 001 until the steel cables 12 do not contact the lower tower barrel 001. Next, control to start all the first motors 10, synchronously driving the corresponding wire wheels 11 to rotate, so that the wire wheels 11 wind up the steel cables 12, and further make the first modules 1, second modules 3 and the corresponding components move towards the direction close to the lower tower barrel 001 until all the electric walking wheels 8 contact the lower tower barrel 001, while the electric telescopic supports 9 are in a contracted state and all the electric telescopic supports 9 do not contact the lower tower barrel 001. At this time, all the steel cables 12 are in a taut state, and the torsion springs between the adapter joints 2 and the first modules 1 are deformed. All the electric walking wheels 8 press tightly on the surface of the lower tower barrel 001. Then, control to start all the electric walking wheels 8 to rotate, synchronously driving the electric actuators 7 and the corresponding components to move upward. Considering that some wind power tower barrels are conical barrels, thicker at the bottom and thinner at the top as Figure 2 shown, therefore, when this equipment moves on the lower tower barrel 001, it is also necessary to synchronously control each wire wheel 11 to wind up the steel cable 12 to make the steel cable 12 taut, thereby realizing the full-automatic walking of this equipment outside the lower tower barrel 001.

[0034] When the device moves to the top of the lower tower barrel 001, the three electric walking wheels 8 on the first module 1 still contact the lower tower barrel 001, enabling the device to move upward stably. When the electric walking wheels 8 of the second module 3 have passed over the top of the lower tower barrel 001, at this time, control to stop all the electric walking wheels 8, and simultaneously control the electric telescopic support feet 9 on the first module 1 to extend. The electric telescopic support feet 9 and the electric walking wheels 8 support each first module 1. And at this time, control the first motor 10 on the second module 3 to reverse. At this time, the torsion spring between the adapter 2 and the first module 1 recovers, and the wire wheels 11 on the second module 3 unwind the steel cable 12. The adapter 2 drives the second module 3 to rotate away from the lower tower barrel 001, like a blooming flower shape. Then control the external crane to lift the upper tower barrel 002 and transfer it above the lower tower barrel 001. Generally, wind power tower barrels are connected by flanges. Several guiding columns are arranged on the upper part of the wind power tower barrel, and pin holes are arranged on the lower part of the wind power tower barrel to cooperate with the guiding columns. Then the wind power tower barrels are fixed by bolts. After the external crane transfers the upper tower barrel 002 above the lower tower barrel 001, it is necessary to match the guiding columns of the lower tower barrel 001 with the pin holes of the upper tower barrel 002. During the matching process, even if there is a laser positioning structure on the external crane, enabling the perfect matching of the wind power tower barrels, only the upper part of the upper tower barrel 002 is lifted by the external crane. The influence of the external motor on lifting and transferring the upper tower barrel 002 and the airflow at high altitude makes the lower part of the upper tower barrel 002 prone to shaking, resulting in an extended matching time between the upper tower barrel 002 and the lower tower barrel 001, thereby affecting the installation efficiency of the wind power tower barrel. Therefore, after the upper tower barrel 002 is slowly transferred above the lower tower barrel 001 through the laser positioning on the external crane, and the guiding column on the lower tower barrel 001 has not entered the pin hole below the upper tower barrel 002, at this time, control to start the first motor 10 of the second module 3, so that the corresponding wire wheels 11 wind up the steel cable 12, thereby shortening the distance between adjacent wire wheels 11. At the same time, the torsion spring between the adapter 2 and the first module 1 is deformed, so that the electric telescopic support feet 9 on the second module 3 move towards the upper tower barrel 002 until some electric telescopic support feet 9 contact the outer wall of the upper tower barrel 002, thereby limiting the lower part of the upper tower barrel 002 and reducing the shaking of the lower part of the upper tower barrel 002. Then, through the adjustment unit on the external crane, drive the upper tower barrel 002 to rotate, thereby adjusting the angle of the upper tower barrel 002. Then, as the wire wheels 11 continuously wind up the steel cable 12, the electric telescopic support feet 9 move towards each other. Finally, all the electric telescopic support feet 9 are pressed against the upper tower barrel 002. At this time, the axial positioning of the upper tower barrel 002 and the lower tower barrel 001 is completed, and the upper tower barrel 002 is located directly above the lower tower barrel 001. Then control the external crane to lower the upper tower barrel 002, and at the same time control the electric telescopic support feet 9 on the second module 3 to contract, so that the electric walking wheels 8 of the second module 3 reverse, guiding the upper tower barrel 002 to be lowered.Until the guide post of the lower tower barrel 001 is inserted into the pin hole of the upper tower barrel 002, and then the staff can fix the lower tower barrel 001 and the upper tower barrel 002 with bolts, effectively reducing the matching time between the wind power tower barrels and improving the modular installation efficiency of the wind power tower barrels.

[0035] The second embodiment

[0036] Based on the first embodiment, according to Figures 1 - 6 As shown, it further includes a U-shaped plate 101, a second motor 102 and an inflatable roller 103; the middle part of the second module 3 is connected with a U-shaped plate 101; a diversion groove 10101 is opened in the U-shaped plate 101; a second motor 102 is installed on the upper part of the U-shaped plate 101; an inflatable roller 103 is fixedly connected to the output shaft of the second motor 102; the inflatable roller 103 is rotatably connected with the U-shaped plate 101; the inflatable roller 103 is rotatably connected with the second module 3.

[0037] The outer surface of the inflatable roller 103 is provided with a wear-resistant rubber cushion layer.

[0038] It further includes an air pump 104; the air pump 104 is installed at the lower part of the diversion groove 10101; the inflatable roller 103 is composed of a middle hollow rotating shaft and an airbag tire, the hollow rotating shaft is communicated with the airbag tire, and a plurality of air holes 10301 are opened at the upper part of the hollow rotating shaft; the diversion groove 10101 is communicated with the corresponding air holes 10301.

[0039] A dust-proof net is arranged at the air inlet of the air pump 104.

[0040] The outer surface of the electric telescopic support leg 9 is provided with a wear-resistant rubber cushion layer for increasing the contact friction between the electric telescopic support leg 9 and the outer walls of the lower tower barrel 001 and the upper tower barrel 002.

[0041] The working steps of the above embodiment are as follows:

[0042] On the basis of the above operations, it should also be considered that the guiding columns of the lower tower barrel 001 need to be fully matched with the pin holes on the upper tower barrel 002 to complete the installation of the wind power tower barrel. However, the staff cannot move the upper tower barrel 002 to adjust the angle of the upper tower barrel 002. The external motor only suspends the upper part of the upper tower barrel 002. To adjust the angle of the upper tower barrel 002, it is necessary to adjust the angle of the upper tower barrel 002 through the rotating mechanism of the external crane. It is easy to rotate the upper tower barrel 002 excessively, resulting in the situation that the upper tower barrel 002 and the lower tower barrel 001 cannot be matched. The adjustment is difficult, resulting in a low assembly efficiency of the wind power tower barrel. Therefore, before the guiding column of the lower tower barrel 001 is inserted into the pin hole on the upper tower barrel 002, the electric telescopic support feet 9 on the second module 3 have completed positioning the upper tower barrel 002 directly above the lower tower barrel 001. At this time, the air pump 104 is controlled to start, and the external air is compressed and enters the diversion groove 10101 and then enters the inflatable roller 103 through the air hole 10301, so that the airbag tires of the inflatable roller 103 expand until all the inflatable rollers 103 are pressed tightly on the upper tower barrel 002. Then, the electric telescopic support feet 9 on the second module 3 are controlled to contract. At this time, the inflatable roller 103 replaces the electric telescopic support feet 9 to position the upper tower barrel 002. Then, the three second motors 102 are controlled to start, and the inflatable rollers 103 are synchronously driven to rotate slowly in the same direction. The inflatable rollers 103 drive the upper tower barrel 002 to rotate through static friction, thereby realizing the angle adjustment of the upper tower barrel 002. After the pin hole on the upper tower barrel 002 is aligned with the guiding column of the lower tower barrel 001, the second motor 102 is controlled to stop, and the electric actuator 7 on the second module 3 is controlled to extend, so that the corresponding electric walking wheels 8 are clamped on the upper tower barrel 002. Then, the air pump 104 pumps out the air in the corresponding inflatable rollers 103, and all the inflatable rollers 103 are separated from the upper tower barrel 002. Then, the external crane cooperates with the electric walking wheels 8 of the first module 1 to lower the upper tower barrel 002 and make the upper tower barrel 002 and the lower tower barrel 001 cooperate precisely and efficiently. After the assembly of this module is completed, then all the electric walking wheels 8 can be controlled to move upward to install the next wind power tower barrel module.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present invention.
