[0043] Working principle:

[0044] When using the anti-falling wind turbine tower maintenance platform, the monitoring range of the speed detector 9 is set in advance through the control terminal 6, and when the value detected by the speed detector 9 is greater than the pre-set range, the control terminal 6 will immediately drive the two electric telescopic rods 815 to immediately retract to the limit position to limit the two limiting plates 806;

[0045] When the anti-falling wind turbine tower maintenance platform is needed, the winch 3 is first operated through the control terminal 6, the winch 3 is operated to drive the steel cable to be wound, thereby driving the U-shaped plate 4 to rise, the U-shaped plate 4 is driven to rise, the platform body 5 is driven to move, the multiple extension plates 701 are driven to move, and the multiple pulleys 702 are driven to move in the multiple vertical grooves 7, thereby ensuring that the platform body 5 stably rises;

[0046] When the platform body 5 rises, the two limiting plates 806 are driven to move upwards, one end of the top surface of the two limiting plates 806 is in an inclined state and is parallel to the top inner wall surface of the plurality of limiting grooves 801, the limiting plate 806 is pushed by the limiting groove 801 when rising, so that the two limiting plates 806 move towards each other, and the movement of the two limiting plates 806 will squeeze the plurality of springs 805, so that the plurality of springs 805 are compressed under stress, when the two limiting plates 806 move to one side of the upper two limiting grooves 801, the rebound force of the plurality of springs 805 will make the two limiting plates 806 reinserted in the corresponding two limiting grooves 801, when the cable breaks, the two limiting plates 806 will hinder the platform from falling, ensuring the safety of the maintenance personnel;

[0047] When the platform body 5 needs to be lowered after the maintenance is completed, the control terminal 6 is operated to run the two electric telescopic rods 815, the output end of the two electric telescopic rods 815 is elongated, so as to drive the two cross plates 816 to move, the plurality of hinged plates 813 are moved by the movement of the two cross plates 816, the plurality of movable blocks 812 are moved by the movement of the plurality of hinged plates 813, since one side surface of the plurality of movable blocks 812 abuts against one side inner wall surface of the plurality of grooves 810, the plurality of movable blocks 812 are moved to drive the two long plates 809 to move, so that the two limiting plates 806 are separated from the inside of the corresponding two limiting grooves 801, and then the winch 3 is operated to lower;

[0048] When the cable breaks when the platform body 5 is lowered, the platform body 5 falls rapidly, the value detected by the speed detector 9 is greater than the pre-set range, the control terminal 6 immediately operates the two electric telescopic rods 815, so that the two electric telescopic rods 815 are retracted to the extreme position, so as to drive the plurality of hinged plates 813 to move, the plurality of movable blocks 812 are moved by the movement of the plurality of hinged plates 813, the two long plates 809 are pushed by the movement of the plurality of movable blocks 812, the two long plates 809 are moved to drive the two limiting plates 806 to move, so that the two limiting plates 806 are immediately inserted into the corresponding limiting grooves 801, preventing the platform body 5 from falling, ensuring the safety of the maintenance personnel;

[0049] Through the cooperation of the above structure, the limiting plate 806 and the limiting groove 801 cooperate, the platform body 5 is provided with anti-falling treatment when rising or falling, avoiding the rapid falling of the maintenance platform when the cable breaks, and avoiding safety accidents.

[0050] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
