The invention discloses an anti-skid device for a climbing-free device for a wind turbine generator and a design method thereof. The anti-skid device for the climbing-free device for the wind turbinegenerator comprises a power box, driving wheels, driven wheels, a steel rope and a pre-tightening spring; the driving wheels and the driven wheels are installed in the power box; at least two drivingwheels are arranged; the steel rope passes through the power box and sequentially bypasses the driving wheels and the driven wheels; the power box is internally provided with a guide groove; at leasttwo driven wheels are floating wheels; a wheel shaft of each floating wheel is installed inside the guide groove; and the wheel shafts of the floating wheels are connected through the pre-tightening spring. According to the anti-skid device disclosed by the invention, a plurality of small-diameter driving wheels are used to replace a single large-diameter driving wheel in the existing design; thecontact length between the driving wheels and the steel rope is increased; reliable running of a transmission system is guaranteed; the transmission capability of the driving wheels is also improved;and the skid resistance of the climbing-free device under extremely severe working conditions is improved.
Description
technical field [0001] The invention relates to the field of maintenance equipment for wind turbines, in particular to an anti-skid device for a climb-free device of a wind turbine and a design method thereof. Background technique [0002] With the increase of the power of a single wind turbine unit, the height of the tower is also increased. The standard climbing aids previously equipped with the unit can no longer meet the needs of personnel getting on and off the cabin. More and more complete machine manufacturers will use the climbing aids As a standard configuration for units with a power level of 2MW and above. The current working mode of the unit climbing device is: the motor drives the driving wheel, and the driving wheel transmits the driving force to the steel wire rope through sliding friction. Cooperating with the fixed pulley arranged on the ladder, the steel wire rope drives the part of the manned platform to realize the lifting function. [0003] The existing...
