DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0020] Embodiment 1 A modular installation device for a wind turbine tower, according to Figure 1-Figure 6 As shown, it includes a first module 1; a plurality of first modules 1 are sequentially connected to each other to form a circular ring structure, all the first modules 1 are distributed in a circular array as a whole, and each first module 1 is provided with a rechargeable battery; It also includes an adapter 2, a second module 3, a moving component and a winding component; each first module 1 has an adapter 2 hinged on the rotating upper part; a torsion spring is provided between each adapter 2 and the corresponding first module 1; each adapter 2 has a second module 3 fixedly connected to the upper part; the first module 1 and the second module 3 are each connected to a moving component; each two adjacent first modules 1 are connected to a winding component; and each two adjacent second modules 3 are also connected to a winding component.

[0021] The moving component includes an electric actuator 7, electric walking wheels 8, and electric telescopic support feet 9; several electric actuators 7 are respectively installed on each of the 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 foot 9 is installed on each electric walking wheel 8.

[0022] All the electric actuators 7 on the same first module 1 are distributed in a "pin" shape as a whole, which is used to maintain the stability of the first module 1 during walking.

[0023] The winding component includes a first motor 10, a wire wheel 11, and a steel cable 12; among every two adjacent first modules 1, a first motor 10 and a wire wheel 11 are installed on one of the first modules 1, 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.

[0024] 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 second module 3.

[0025] The working steps of the above embodiment are as follows: First, the external crane lifts the bottom layer of the lower tower 001 and fixes it on the preset pile foundation. At this time, the equipment can be assembled, and the first module 1 is arranged in a circular ring around the lower tower 001, and the fixed wheel 111 fixed with the steel cable 12 is fixed to the corresponding first module 1 and the second module 3 by bolts, so that the first module 1, the second module 3, the steel cable 12 and the corresponding parts form a circular ring around the outside of the lower tower 001, and the electric running wheel 8 and the electric telescopic support leg 9 are in contact with the lower tower 001, and then all the electric actuators 7 are controlled to extend, and the corresponding electric running wheels 8 and the electric telescopic support legs 9 are synchronously driven to move in the direction close to the lower tower 001 until the steel cable 12 does not contact the lower tower 001, and then the control All the first motors 10 are controlled to start, and the corresponding wire wheels 11 are synchronously driven to rotate, so that the wire wheels 11 reel in the steel cables 12, thereby moving the first module 1, the second module 3 and the corresponding components toward the lower tower 001, until all the electric running wheels 8 are in contact with the lower tower 001, and the electric telescopic legs 9 are in a retracted state, and all the electric telescopic legs 9 are not in contact with the lower tower 001. At this time, all the steel cables 12 are in a taut state, and the torsion springs between the adapter 2 and the first module 1 are deformed, and all the electric running wheels 8 are pressed against the surface of the lower tower 001. Then all the electric running wheels 8 are controlled to start rotating, and the electric actuator 7 and the corresponding components are synchronously driven to move upward, taking into account that some wind turbine towers are conical, thick at the bottom and thin at the top. Figure 2 As shown, when the device moves on the lower tower 001, it is also necessary to synchronously control the winding of the steel cable 12 by each wire wheel 11 to make the steel cable 12 taut, thereby realizing the fully automatic walking of the device outside the lower tower 001.

[0026] When the equipment moves to the top of the lower tower 001, the three electric running wheels 8 on the first module 1 are still in contact with the lower tower 001, so that the equipment can move upward stably. When the electric running wheels 8 of the second module 3 have passed the top of the lower tower 001, all the electric running wheels 8 are controlled to stop, and the electric telescopic legs 9 on the first module 1 are synchronously controlled to extend. The electric telescopic legs 9 and the electric running wheels 8 support each first module 1, and the first motor 10 on the second module 3 is controlled to reverse. At this time, the torsion spring between the adapter 2 and the first module 1 is restored, and the wire wheel 11 on the second module 3 unwinds the steel cable 12. The adapter 2 drives the second module 3 to rotate to the side away from the lower tower 001, like a blooming flower, and then The external crane is controlled to lift the upper tower 002 and transfer it to the top of the lower tower 001. Generally, the wind turbine tower is connected through a flange. Several guide columns are set on the upper part of the wind turbine tower, and pin holes are set on the lower part of the wind turbine tower to cooperate with the guide columns. Then the wind turbine tower is fixed by bolts. After the upper tower 002 is transferred to the top of the lower tower 001 by the external crane, the guide columns of the lower tower 001 need to be matched with the pin holes of the upper tower 002. During the matching process, even if there is a laser positioning structure on the external crane, so that the wind turbine tower can be perfectly matched, the external crane only lifts the upper part of the upper tower 002. The external motor is lifting and transferring the upper tower 002 and the influence of the airflow in the high altitude makes the upper tower The lower part of 002 is prone to shaking, which prolongs the pairing time of the upper tower 002 and the lower tower 001, thereby affecting the installation efficiency of the wind turbine tower. Therefore, after the upper tower 002 is slowly transferred to the top of the lower tower 001 through the laser positioning on the external crane, the guide column on the lower tower 001 has not yet entered the pin hole below the upper tower 002. At this time, the first motor 10 of the second module 3 is controlled to start, so that the corresponding wire wheel 11 reels the steel cable 12, thereby shortening the distance between adjacent wire wheels 11, and at the same time, the torsion spring between the adapter 2 and the first module 1 is deformed, so that the electric telescopic support leg 9 on the second module 3 moves towards the upper tower 002, until part of the electric telescopic support leg 9 contacts the outer wall of the upper tower 002, and the electric telescopic support leg 9 is moved to the upper tower 002. This limits the lower part of the upper tower 002 to reduce the shaking of the lower part of the upper tower 002, and then drives the upper tower 002 to rotate through the adjustment unit on the external crane, thereby adjusting the angle of the upper tower 002, and then as the wire wheel 11 continues to reel in the steel cable 12, the electric telescopic legs 9 move towards each other, and finally all the electric telescopic legs 9 are pressed against the upper tower 002. At this time, the axial positioning of the upper tower 002 and the lower tower 001 is completed, and the upper tower 002 is located directly above the lower tower 001. Then the external crane is controlled to lower the upper tower 002, and at the same time, the electric telescopic legs 9 on the second module 3 are controlled to retract, so that the electric walking wheels 8 of the second module 3 are reversed to guide the lowering of the upper tower 002.Until the guide column of the lower tower 001 is inserted into the pin hole of the upper tower 002, the staff can then bolt the lower tower 001 and the upper tower 002, which effectively reduces the coordination time between wind turbine towers and improves the efficiency of modular installation of wind turbine towers.

[0027] Second embodiment On the basis of the first embodiment, according to Figure 1-Figure 6 As shown, it also includes a U-shaped plate 101, a second motor 102 and an inflatable roller 103; the U-shaped plate 101 is connected to the middle of the second module 3; a guide groove 10101 is opened in the U-shaped plate 101; the second motor 102 is installed on the upper part of the U-shaped plate 101; each output shaft of the second motor 102 is fixedly connected to an inflatable roller 103; the inflatable roller 103 is rotatably connected to the U-shaped plate 101; the inflatable roller 103 is rotatably connected to the second module 3.

[0028] The outer surface of the inflatable roller 103 is provided with a wear-resistant rubber cushion layer.

[0029] It also includes an air pump 104; the air pump 104 is installed at the lower part of the guide groove 10101; the inflatable roller 103 is composed of a hollow shaft in the middle and an airbag tire, the hollow shaft is connected to the airbag tire, and a plurality of air holes 10301 are opened on the upper part of the hollow shaft; the guide groove 10101 is connected to the corresponding air holes 10301.

[0030] A dustproof net is provided at the air inlet of the air pump 104 .

[0031] The outer surface of the electric telescopic support leg 9 is provided with a wear-resistant rubber cushion layer, which is used to increase the contact friction between the electric telescopic support leg 9 and the outer walls of the lower tower 001 and the upper tower 002.

[0032] The working steps of the above embodiment are: On the basis of the above operations, it is also necessary to consider that the guide column of the lower tower 001 must be fully matched with the pin hole on the upper tower 002 to complete the installation of the wind turbine tower, and the staff cannot move the upper tower 002 to adjust the angle of the upper tower 002, and the external motor only hangs the upper part of the upper tower 002. To adjust the angle of the upper tower 002, it is necessary to adjust the angle of the upper tower 002 through the rotating mechanism of the external crane, which is prone to excessive rotation of the upper tower 002, resulting in the upper tower 002 and the lower tower 002 being out of alignment. 01 cannot match, the adjustment is difficult, resulting in low assembly efficiency of the wind turbine tower. Therefore, before the guide column of the lower tower 001 is inserted into the pin hole of the upper tower 002, the electric telescopic support leg 9 on the second module 3 has completed the positioning of the upper tower 002 to the top of the lower tower 001. At this time, the air pump 104 is controlled to start, and the external air is compressed and enters the guide groove 10101 and then enters the inflatable roller 103 through the air hole 10301, so that the airbag tire of the inflatable roller 103 is inflated until all the inflatable rollers 103 are The electric telescopic legs 9 on the second module 3 are all pressed tightly on the upper tower 002, and then the electric telescopic legs 9 on the second module 3 are controlled to shrink. At this time, the pneumatic rollers 103 replace the electric telescopic legs 9 to position the upper tower 002, and then the three second motors 102 are controlled to start, synchronously driving the pneumatic rollers 103 to rotate slowly in the same direction. The pneumatic rollers 103 drive the upper tower 002 to rotate through static friction, thereby achieving the angle adjustment of the upper tower 002. After the pin hole on the upper tower 002 is aligned with the guide column of the lower tower 001, the second motor 102 is controlled to stop, and the second The electric actuator 7 on the module 3 extends, so that the corresponding electric running wheel 8 is clamped on the upper tower 002, and then the air pump 104 extracts the air in the corresponding inflatable roller 103, and all the inflatable rollers 103 are separated from the upper tower 002. Then the external crane cooperates with the electric running wheel 8 of the first module 1 to lower the upper tower 002 and make the upper tower 002 and the lower tower 001 cooperate accurately and efficiently. After completing the assembly of the module, all the electric running wheels 8 can be controlled to move upward to install the next wind turbine tower module.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
