Referring to fig. 1-4, the present utility model is described in detail by the following embodiments:

the utility model provides a wind-powered electricity generation tower section of thick bamboo overhauls device of crawling, is equipped with on binding up steel band 4 and crawls the drive and bind up steel band tightening end 2 and crawl drive power supply and carry on end 3, still includes:

the crawling drive overhauling end 1 is driven by a driving system, so that the overhauling system in the crawling drive overhauling end 1 realizes multi-degree-of-freedom overhauling operation on overhauling sections of different parts of the wind turbine blade under the action of a rotating element. The two crawling driving binding steel belt tightening ends 2 are symmetrically arranged on the binding steel belt 4, one crawling driving overhauling end 1, the two crawling driving binding steel belt tightening ends 2 and the crawling driving power supply carrying end 3 are arranged in a four-quadrant point mode on the binding steel belt 4, so that the dead weight of the device can be uniformly distributed on the surface of the tower barrel, and the phenomenon that the load of the tower barrel exceeds standard due to the overweight of the device is prevented, and fatigue and damage are generated.

The crawling drive overhauling end 1 comprises a crawling drive overhauling end body 12 and a magnetic track 13, and the crawling drive overhauling end body 12 is connected with the binding steel belt 4.

The maintenance system is a four-axis mechanical fault maintenance arm 11 and is positioned on a crawling drive maintenance end machine body 12. The driving system is arranged on the inner side of each quadrant point and drives the magnetic caterpillar 13 to move so as to drive the maintenance device to integrally move. The four-axis mechanical trouble shooting arm 11 includes an operation element and a four-axis mechanical trouble shooting arm base 1112, and the four-axis mechanical trouble shooting arm base 1112 is located above the crawling drive overhaul end body 12 for fixed installation of the overhaul system.

The rotating element includes a second cantilever 1107, a first cantilever 1109, and a rotating disk 1111, the rotating disk 1111 being located above a four-axis mechanical troubleshooting arm base 1112 and rotatably adjusting the orientation of the troubleshooting system. The turning element further comprises a third rotational axis 1106, a second rotational axis 1108 and a first rotational axis 1110, the first rotational axis 1110 causing the first cantilever 1109 to turn on the rotating disc 1111, the second rotational axis 1108 causing the second cantilever 1107 to turn on the first cantilever 1109, the third rotational axis 1106 causing the operating assembly to turn on the second cantilever 1107. The first rotation shaft 1110 is fixedly coupled to an upper end of the rotation plate 1111.

The operating components are a high-pressure cleaning water gun 1101, an ultrasonic flaw detector 1102, an ultrasonic couplant 1103, a camera 1104 and an ultrasonic range finder 1105. The ultrasonic flaw detector 1102 and the ultrasonic couplant 1103 are positioned at the same horizontal position, and the camera 1104 and the ultrasonic range finder 1105 are positioned at the same horizontal position.

When the device is in standby, the driving system and the overhauling system are both positioned at the bottom end of the tower cylinder, and the wireless charging receiving end, close to one side of the tower cylinder, of the driving system is butted with the wireless charging coil on the surface of the tower cylinder, so that the wireless charging work of the device is carried out. When the device works, the directional wireless charging system is started first, and remote wireless directional charging is carried out on the directional wireless charging receiving end of the driving system. The device driving system is started, the magnetic caterpillar 13 climbs upwards along the vertical direction, and the magnetic caterpillar moves to the position of the broken height of the wind turbine blade point to stop creeping. The wind turbine is stopped and the blade to be overhauled is controlled to rotate to the angle parallel to the tower. The device driving system is started again, the control motor rotates the magnetic track 13 by 90 degrees along any direction, so that the magnetic track 13 crawls along the horizontal direction, and after the maintenance system is aligned to the blade direction, the control motor rotates the magnetic track 13 by 90 degrees along any direction again, so that the magnetic track 13 rotates back to the vertical direction.
