Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0033] Such as figure 1 As shown, a wind power tower structure with high safety includes a vertical tower 1, and a lift 3, a vertical ladder 2, and a power transmission cable 4 are arranged inside the tower, and the lift is mainly used for materials Of course, it can also be used for the lifting of personnel; while the human climbing ladder is used for the operation and maintenance personnel to climb up and down. Similar to the prior art, the elevator includes a lifting guide rail 31, a car 32 that can move up and down on the lifting guide rail, a driving device (not shown) arranged on the top of the lifting guide rail, and the driving device is driven by a wire rope 34 The car moves up and down, and the lifting guide rail includes two vertical slide rails 311, some reinforcing links 312 transversely connected between the two slide rails. Sin...

The invention discloses a high-safety wind power tower drum structure. The tower drum structure comprises a tower drum, a lifting guide rail used for supporting a lift car, a person ladder stand and a power transmission cable, wherein a driving device drives the lift car to move up and down through a steel wire rope, a fixed support is arranged in the tower drum and fixedly connected with the person ladder stand and the lifting guide rail, a cable fixing block is arranged between the person ladder stand and the lifting guide rail, the power transmission cable is connected to the cable fixing block, the driving device comprises a traction machine and a synchronous motor, a winding drum provided with the steel wire rope in a winding mode and a worm gear are arranged on an output shaft of the traction machine, a worm meshed with the worm gear is arranged on an output shaft of the synchronous motor, the transmission ratio of the worm to the worm gear is w, the rotating speed of the traction machine and the rotating speed of the synchronous motor are n1 and n2, and the rotating speed ratio of the traction machine to the synchronous motor is controlled within the following range: 1 / 1.1w<=n1 / n2<=1 / w. According to the tower drum structure, the safety of workers during assembling, overhaul and maintenance can be remarkably improved, and the power transmission cable is convenient to overhaul and maintain.
Description
technical field [0001] The invention relates to the technical field of wind power generators, in particular to a wind power tower structure with high safety. Background technique [0002] With the continuous enhancement of people's awareness of environmental protection, the popularity of wind power generation is getting higher and higher, and accordingly, wind power generators have also developed rapidly. The current wind power generator usually includes a vertical tower and wind blades arranged on the top of the tower. When the wind blades are rotated by a sharp action, electric energy can be generated. It is understandable that we need to arrange corresponding power transmission cables inside the tower. In addition, in order to facilitate assembly and later maintenance, it is also necessary to set up a ladder and an elevator on the tower. The ladder is used for maintenance personnel to go up and down the tower for assembly or maintenance, and the elevator is mainly used f...
