The implementation principle of the embodiment is as follows: when the wind power generation tower needs to be overhauled, the maintainers enter the lifting cavity 3 from the passing cavity 6. When going to electricity generation room 2 before needing and examining and repair, the maintainer stands on transport plate 11, starts electric block 13, and electric block 13 drives 16 upward movements of couple, thereby 16 pulling conveying chain 17 of couple drive transport plate 11 upward movement in lift slide 9, and then drive the maintainer and go up and down. The transport plate 11 is limited by the translation slide way 10 when rising to the joint of the lifting slide way 9 and the translation slide way 10, and cannot move upwards continuously at the moment until reaching the highest point. The service personnel can now enter the electricity generating chamber 2 for service work by climbing the ladder 51.

When the tower needs to go to the outside of the tower for related maintenance work, the roller motor 15 is started, the roller motor 15 drives the roller 14 to start moving, and the roller 14 is driven by the horizontal movement on the transportation rail 12. The movement of the roller 14 drives the electric hoist 13 to move, and further drives the hook 16 to move, so as to drive the transportation plate 11 to move horizontally in the translation slideway 10. The transport plate 11 moves toward the access door 71 until the opening/closing protrusion 112 of the transport plate 11 is inserted into the opening/closing through groove 181 of the opening/closing slider 18, and then the transport plate 11 pushes the opening/closing slider 18 to move toward the access door 71. In the process that the opening and closing slide block 18 moves towards the access door 71, the opening and closing linkage slide groove 22 moves along with the opening and closing slide block, so that the linkage column 23 on the access door 71 is driven to move, the motion track of the linkage column 23 is in a circular arc shape, and the motion of the linkage column 23 drives the access door 71 to move, so that the door opening action is completed. When the linkage column 23 moves to the end point of the linkage sliding groove 22, the linkage column cannot move continuously, the opening and closing sliding block 18 is locked at the moment and reaches the maximum displacement value, the opening and closing sliding block 18 extends out of the tower body 1 to form a platform, and a maintainer can stand on the opening and closing sliding way to perform maintenance work.

After the maintenance work outside the tower is completed, the maintainer returns to the tower body 1, stands on the transport plate 11, steps on the second locking slide block 20, moves the second locking slide block 20 downwards, pushes the pair of first locking slide blocks 19 to move towards the direction away from each other, the first locking slide blocks 19 extend out from the two sides of the opening and closing protrusion 112, and collide and extrude the inner wall of the opening and closing through groove 181, and the motion of the transport plate 11 can drive the motion of the opening and closing slide block 18 at the moment. At this time, the motor of the start roller 14 drives the transport plate 11 to move away from the access door 71, and further drives the opening and closing slide block 18 to move away from the access door 71. The movement of the opening and closing slide block 18 makes the linkage chute 22 move, and then drives the linkage column 23 to move, and the linkage column 23 drives the access door 71 to move, thereby completing the door closing action. When the access door 71 is closed, the second locking slide 20 is released, and the return spring 21 drives the first locking slide 19 to move in a direction to approach each other, so that the connection between the transport plate 11 and the opening/closing slide 18 is disconnected.

After the maintenance work is accomplished, on control transport plate 11 got back to lift slide 9 again, start electric block 13, drive 16 downstream of couple to drive transport plate 11 downstream, until getting back to the bottom in lift chamber 3, then the maintainer leaves transport plate 11, from current chamber 6 walk out tower body 1 can.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
