Abstract

Disclosed is a safety platform in a large-scale wind turbine tower barrel, which is technically characterized in that in the tower barrel, a safety platform is disposed by every certain height, simultaneously each layer of safety platform is designed with a corresponding goods passage and a walking passage, the passages run through from up to down, after mounting a winch in a chamber of a wind-driven generator, the safety platform can effectively guard against work personnel from high altitude falling and high altitude precipitation, and simultaneously brings convenience for the work personnel to convey relatively heavy goods to required places.

Description

Security platform in a kind of large fan tower tube

Technical field

The utility model belongs to wind power generation field, is specifically related to the internal structure of large fan tower tube, and multistage safe half space is provided, and provides more careful protection to staff's life safety.

Technical background

Present wind-driven generator generally is made up of several parts such as generator, cabin, hub, blade, tower tube, column foot and switch board rooms, and highly substantially all about 60m or higher, tower tube diameter is between 2--4m than the tower tube of relatively large wind-driven generator.But present domestic most of unit is not all installed special-purpose lift, usually the staff climbs to the cabin of cat head by the ladder of tower tube inside, though in tower tube inside, but too high height makes the danger that this work is still compared, consequence is hardly imaginable in case the staff falls, and perhaps the bob thing in high-altitude also can bring great danger to the staff.

At this hidden danger at present mostly blower fan tower barrel all be the way that adopts safety strip that staff and ladder are connected together, this method has reduced the risk that personnel fall to a certain extent, but does not but still have enough strick precautions for falling object from high altitude.

Summary of the invention

Sign in present the deficiencies in the prior art, the object of the present invention is to provide the security platform in a kind of large fan tower tube, effectively the prevention work personal height falls and is subjected to the risk of falling object from high altitude, makes things convenient for the heavy article of staff to be transported to the place that needs simultaneously.

For achieving the above object, the security platform in a kind of large fan tower tube of the present invention, its technological scheme is achieved in that

In the inner every rising certain height of tower tube a security platform just is set, even the staff slips to fall in the process of climbing and also can not drop to bottommost so always, and stair platform can also make the staff when climbing a place of having a rest and stopping can be arranged, and has effectively got rid of simultaneously in the tower tube because the potential faults that falling object from high altitude brings staff's safety; While each layer platform all designs corresponding article passage and personnel go up lower channel, and passage up/down perforation, after in the cabin of wind-driven generator capstan winch being installed, the workmen that is convenient to operation will compare heavy device and lift in the cat head cabin by the cabin capstan winch.

Description of drawings

Figure 1 shows that the blower fan tower barrel partial schematic diagram, comprised a security platform.

Figure 2 shows that the schematic representation of whole tower tube, expressed the arrangement and the relevant information of security platform.

Among the figure: 1, tower tube; 2, ladder; 3, Huo Dong door; 4, opening a; 5, security platform; 6, opening b; 7 cabins; 8, air blade; 9, capstan winch; 10, hoist cable.

Embodiment

Shown in accompanying drawing 2, by every rising one segment distance of base portion a security platform 5 is set in tower tube 1 inside, leave two opening a,

b

4,6 on each security platform 5, wherein the opening a4 at ladder 2 places passes through for people's climbing, and the door 3 that a fan activity is arranged, whenever the staff bars up corresponding movable door 3 by such security platform 5 backs, open door when that is to say except the staff by opening a 4, it is to close that other times all keep door, if throw so because of carelessness on the security platform 5 that will drop on the below, can not fall always; Another opening b 6 is with the passage of pulley toward the article of hanging oneself, and article passage up/down perforation can lift article to cat head cabin 7 by hoist cable 10 by the capstan winch 9 that install in cabin 7.

Claims

1, the security platform in a kind of large fan tower tube is characterized in that: in the tower tube, upwards every a segment distance stair platform is set from column foot, leaves two openings on each platform, ladder is by one of them hole.

2, the security platform in a kind of large fan tower tube according to claim 1, it is characterized in that having on the opening that ladder passes through one can folding door.

3, the security platform in a kind of large fan tower tube according to claim 1 is characterized in that tower tube top is equipped with a capstan winch.
