Description

An internal lifting platform of a wind power generation tower

technical field

The utility model relates to the field of wind power generation equipment, in particular to an internal lifting platform of a wind power generation tower driven by a rack and pinion.

Background technique

As a clean and renewable resource, wind energy has attracted more and more attention from all over the world. The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the rotation speed through the speed increaser to promote the generator to generate electricity. In order to obtain Large and uniform wind force, the height of the tower design is very high. At present, for the convenience of maintenance, the wind power tower is generally equipped with a ladder inside the tower. When the wind power tower fails, the maintenance personnel can climb to the fault location. Carry out timely maintenance, however, due to the high design height of the existing wind power generation tower, the maintenance personnel spend time and physical strength artificially climbing the ladder, the labor intensity is high, and the risk factor increases under the fatigue state of the climbing ladder, threatening the life of the maintenance personnel Safety, while affecting the normal maintenance of the tower, shortening the service life of the tower.

Contents of the invention

In order to overcome the deficiencies of the existing maintenance technology for wind power generation towers, the utility model provides an internal lifting platform of wind power generation towers, which has a high safety factor and can avoid the safety hazards of maintenance personnel climbing ladders, save time and effort, and extend the length of wind power generation towers. shelf life.

The technical solution adopted by the utility model to solve the technical problem is that an internal lifting platform of a wind power generation tower includes a guide rail, a power box and a bearing box, the guide rail is vertically arranged inside the tower, and the top of the guide rail is connected to the The top of the tower is fixed, the guide rail is I-shaped, and the outer walls on both sides are provided with racks. The power box includes a motor, a reducer, a gear and a rotating shaft. The motor drives the rotating shaft to rotate through the reducer, and the middle of the rotating shaft The position is provided with a gear, the gear is meshed with the rack on the guide rail, the two ends of the rotating shaft are installed on the wall of the power box through bearings, the outer side of the bearing is provided with a bearing end cover, and the bearing box is fixed on the power box On the upper side of the body, an entrance is provided on one side of the bearing box to carry the maintenance personnel to the maintenance height.

The beneficial effect of the utility model is that the internal lifting platform of a wind power generation tower can avoid the potential safety hazards of maintenance personnel climbing ladders by setting a power box engaged with gears and racks. The maintenance and repair are convenient, and the service life of the wind power tower is extended.
