Abstract

The invention relates to a serialized multi-type small-size manned lifter arranged in a V-shaped cat ladder of a wind generator tower drum. The wind tower lifter can be directly arranged at the inner side of the V-shaped cat ladder of the wind generator tower drum, and a main engine is arranged between two sets of guide rails. A chain or a wire rope hanging on the top of the V-shaped cat ladder is tensioned downward through a traction wheel set in a case, so that the main engine is enabled to hang at the inner side of the V-shaped cat ladder. An electromotor in the case is started, the operation of the traction wheel sets are slowed down by a worm reduction gear; the main engine can run up and down along the guide rails by traction of the chain or the wire rope, or two sets of gear racks, gear bands or chains, which are with the same teeth spaces, are arranged; two wheel gears or two chain wheels, which are with the same number of teeth, arranged at the two ends of an output shaft of the worm reduction gear, are identical with the two sets of gear racks, gear bands or chains; the main engine is arranged at the inner side of the V-shaped cat ladder, The electromotor in the case is started, and the main engine is driven to run up and down along the guide rails by the operation of the two wheel gears or chain wheels at the two ends of the output shaft of the worm reduction gear.

Description

Wind tower elevator

Technical field:

The present invention relates to a kind of small-sized man-engine being arranged on seriation multi-model in wind-driven generator tower People's Bank of China cat ladder.

Background technology:

The unit generating capacity of current aerogenerator improves constantly, and the height of tower cylinder also progressively increases, usual most of wind Ta Neizhipei People's Bank of China's cat ladder or install climb-aiding device additional on People's Bank of China's cat ladder, and daily repair and maintenance personnel rely on manpower climbing up and down completely.The control technology of climb-aiding device is still immature, must join staff on duty to ensure to climb personal security, as mismate easily causes casualties accident during use.

Summary of the invention:

For strengthening the daily attention of aerogenerator, reduce repair and maintenance personnel labor intensity, guarantee repair and maintenance personnel personal safety, improve repair and maintenance work efficiency, the invention provides a kind of installation simple, it is convenient to control, safe and practical aerogenerator special small man-engine.This elevator can be directly installed in wind-driven generator tower People's Bank of China cat ladder, without the need to doing any change to existing facility in tower cylinder.

The technical solution adopted for the present invention to solve the technical problems is:

On 1: two group of guide rails assembling, two standpipes inside People's Bank of China's cat ladder, lower leading wheel is installed in the L-type main frame both sides of cabinet platform and frame composition, and main frame is arranged between two groups of guide rails.The chain or the steel rope that are suspended on People's Bank of China's cat ladder top are strained vertically downward by the traction wheels in cabinet, and main frame is hung on inside People's Bank of China's cat ladder.Start the electrical motor in cabinet, slow down through worm reduction gear and draw wheels running, main frame relies on chain or rope traction to run up and down along guide rail.

2: on the guide rail of technical scheme 1, install the tooth bar of two groups of identical tooth pitches, cingulum or chain, matched with it by two gears of the same number of teeth at the worm reduction gear output shaft two ends in cabinet or sprocket wheel, main frame is arranged on inside People's Bank of China's cat ladder.Start the electrical motor in cabinet, two gears at worm reduction gear output shaft two ends or sprocket wheel running, drive main frame to run up and down along guide rail.

The invention has the beneficial effects as follows that structure is simple, manipulation is convenient, do not need staff on duty to ensure to climb personal security.Main frame is smooth running in People's Bank of China's cat ladder, can stop optional position, the safety of effective guarantee wind tower repair and maintenance personnel, reduces labour intensity.And install simple, quick, do not need to do any change to existing facility in wind tower.
