In order to improve work efficiency and save the physical strength of the staff, a special elevator for the wind turbine tower (patent application number is CN201610243353.3) is specially designed. It learns from the conventional elevator structure and needs to reserve a certain vertical space in the wind turbine tower. Space, and the vertical guide rails for elevator hoisting are arranged around this vertical space, resulting in a large amount of space in the tower

The invention provides a spiral rail elevator and a wind turbine generator system. The spiral rail elevator comprises a spiral rail and a car; the car is provided with a walking mechanism and a driving mechanism; the walking mechanism comprises a bracket, a driving wheel in rolling connection with a rail surface of the spiral rail, and guide wheels clamped on two sides of the spiral rail; the driving wheel and the guide wheels are mounted on the bracket; the bracket is mounted on the car; and the driving mechanism drives the driving wheel, so that the walking mechanism walks along the spiral rail. In the spiral rail elevator and the wind turbine generator system, the elevator, upwards ascended and downwards descended, is arranged along the spiral rail in a tower tube; the elevator can be driven to upwards ascend and downwards descend more stably under the load condition; and the elevator can be used for conveying maintenance equipment and maintained and replaced parts to the top of thetower tube for maintenance of a cabin.
Description
technical field [0001] The invention relates to the technical field of wind power generation, in particular to a spiral track elevator and a wind power generating set. Background technique [0002] Wind turbines are usually tens of meters or even hundreds of meters high. During installation and maintenance of wind turbines, workers have to climb to the nacelle on the top of the wind turbine through a ladder installed in the tower. Climbing to a height of tens of meters or even hundreds of meters puts great demands on the physical strength of the staff. When it is necessary to carry some replacement parts to the engine room, it is necessary to use an additional lifting mechanism to avoid adding extra weight to the staff. load. In order to improve work efficiency and save the physical strength of the staff, a special elevator for the wind turbine tower (patent application number is CN201610243353.3) is specially designed. It learns from the conventional elevator structure and...
