Vertical elevator for wind turbine tower

Abstract

The invention relates to a vertical elevator for a wind turbine tower, which comprises a cage, a power unit, a lifting-point crossbeam and a rigid guide rail, wherein the upper, middle and lower parts of the cage are provided with guide limiting devices; the cage has multiple safety control functions such as double safety lock protection, guide limiting protection, manual descent, escape from the top, alarming and the like; an electric control device and an electric climbing hoist drive the power unit, so that the cage vertically moves along the fixed rigid guide rail to safely, easily and conveniently convey people and objects to an appointed position; and mechanization replaces the traditional manual climb, the labor intensity is reduced, and the work efficiency and safety are improved. The vertical elevator has a compact structure, is suitable for a narrow space, particularly the wind turbine tower, and also can be widely applied to places requiring vertical loading and transportation, such as wind turbine towers, high-rise buildings, towers in the field of military science, large gantry cranes, deep mines, anemometer towers, testing observation towers and the like.

Description

technical field [0001] The invention belongs to the field of lifting equipment, and relates to a vertical lift in a fan tower. Background technique [0002] Due to global warming and energy crisis, countries all over the world are stepping up the development and utilization of environmentally friendly new energy. As a clean, efficient, green and renewable new energy, wind energy has been paid more and more attention by people. my country also regards wind energy as one of the new energy sources for important development. [0003] With the maturity and continuous innovation of wind power generation technology, wind power generating units are gradually developing towards large-scale. In order to obtain a large and stable wind speed, the height of the fan tower is required to be higher and higher, often reaching 80 meters or even higher. This also increases the difficulty of fan maintenance and repair, which is extremely unfavorable to the work intensity and personal safety ...

AI Technical Summary

Problems solved by technology

The former method has low work efficiency, high labor intensity for maintenance personnel, and great potential safety hazards

Although the latter saves some effort for maintenance personnel during the climbing process, it still does not fundamentally solve the climbing problem

And the old-fashioned wind turbine tower does not have enough space to install the existing lifting equipment
