Description

TECHNICAL FIELD

[0002] In the inner wall detection and maintenance operation of a wind power mixed tower (a concrete-steel mixed tower drum), the existing technology relies on a manual basket or a wall-climbing robot based on a guide rail. The manual basket operation has high safety risks and low efficiency, and is significantly affected by environmental factors. Although the traditional guide rail type or wheel type wall-climbing robot realizes automation to a certain extent, it still has the following outstanding technical bottlenecks: The space passability and wall surface adaptability are insufficient. The inner wall of the wind power mixed tower is not an ideal smooth cylindrical surface, and often has concrete joints, embedded parts, reinforcing steel bars, cable supports and other protruding obstacles. The traditional equipment mostly adopts a rigid structure or a simple joint arm, and has limited adjustment capability, so it is difficult to smoothly and reliably avoid such complex obstacles during lifting, and is prone to jamming or collision, which not only affects the normal operation of the equipment, but also may cause damage to the concrete inner wall. It is particularly worth noting that, in order to facilitate maintenance operation, multiple internal platforms are usually arranged at intervals in the mixed tower, which seriously hinder the continuous automatic detection process. The existing equipment must be interrupted when reaching the platform, and the mechanism must be disassembled, repositioned or rely on manual intervention to cross, which leads to discontinuous detection process, low operation efficiency and difficulty in realizing seamless operation.

5. The wind power hybrid tower maintenance equipment as described in claim 1, characterized in that, The first Z-direction drive device is a drive device composed of a servo motor and a sprocket chain.

6. The wind power hybrid tower maintenance equipment as described in claim 1, characterized in that, The second Z-direction drive device is a drive device composed of a servo motor and a lead screw.

7. The wind power hybrid tower maintenance equipment as described in claim 1, characterized in that, A locking device is also provided on the side or rear of the first working platform to lock the first working platform.

8. The method for performing maintenance on the inner wall of a wind turbine tower using the aforementioned wind turbine tower maintenance equipment as described in any one of claims 1-7, characterized in that, Specifically as follows: The wind turbine tower maintenance equipment is placed inside the tower; then, the X-direction drive device moves the first working platform back and forth, moving it from the underside of the first tower track frame to the docking position. Then, the first Z-direction drive device raises the first working platform to a designated height. At this moment, the second working platform is located at the center of the working platform. The clamping device then moves to lock the working frame. When scanning at the height of the first tower track frame, the first working platform locks. After height alignment, the clamping device moves the second working platform. At this time, the main drive wheel of the track rotates. Both ends of the first tower track frame are straight sections. As the main drive wheel enters the interior of the first tower track frame, the auxiliary support wheel also engages with the groove of the first tower track frame. Then, the portion of the second working platform enters the interior of the first tower track frame and rotates. During rotation, the second Z-direction drive device drives the second working platform to rise and fall between the first tower top platform and the second tower top platform, so as to perform close-range scanning or operation on the side wall between the first tower top platform and the second tower top platform. After completing the maintenance work on this level, the section where the second work platform is located will return along the predetermined track. Guided by the end straight track, the second work platform will detach from the first tower track frame and return to the first work platform, completing all maintenance on the first level. Then, the first Z-direction drive device moves the first working platform to the center of the tower, and then descends to the next level. The above operation is repeated to achieve a comprehensive overhaul of the tower's interior.

9. A wind turbine tower maintenance equipment, used for maintenance of the outer wall of the tower, characterized in that, The system includes a main frame, on which a ring-shaped drive device is mounted. A first Z-direction drive device is mounted on the ring-shaped drive device. A first working platform is mounted on the first Z-direction drive device. A Y-direction drive device and a working frame are mounted on the first working platform. The Y-direction drive device drives a clamping device to clamp the working frame and move it in the Y direction. A second Z-direction drive device is fixed on the working frame and drives a second working platform to move up and down. A working device and an image acquisition device are mounted on the second working platform. Auxiliary support wheels and a main track drive wheel are mounted on the top of the working frame.

10. The wind power hybrid tower maintenance equipment as described in claim 9, characterized in that, The aforementioned annular direction drive device is a drive device composed of a servo motor and a gear rack.
