SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome prior art's shortcoming and not enough, provide a novel cat ladder strutting arrangement of large-scale wind generating set that simple structure is reliable, can make cat ladder free end support on cabin or tower section of thick bamboo surface through the device, solve the people and rock the problem when climbing on the cat ladder, make the cat ladder bear more weight, ensure personnel and cat ladder safety.

In order to achieve the above object, the present invention provides a technical solution: the utility model provides a novel cat ladder strutting arrangement of large-scale wind generating set, includes base, rubber pad, nut, gasket and screw rod, wherein, the base designs into a terminal surface big, the little structure of another terminal surface, and the cooperation department of its big terminal surface and rubber pad designs into the wedge for prevent the rubber pad landing, the rubber pad leans on external force to crowd into chucking in the base from big terminal surface to there is one part to stretch out big terminal surface outward, supports on wind generating set's cabin wall or tower section of thick bamboo wall through the rubber pad, can reduce strutting arrangement to cabin wall or tower section of thick bamboo wall surface paint and metallic structure's destruction, the one end welding of screw rod is at the little terminal surface of base, and its other end is equipped with two at least nuts, cliies the cat ladder through these two nuts to it has the gasket to press from both sides between nut and the cat ladder.

Compared with the prior art, the utility model, have following advantage and beneficial effect:

the utility model provides a strutting arrangement simple structure, simple to operate can install in the workshop, also can install in the air at the wind field. Whole strutting arrangement passes through the fixed cat ladder of nut, and its pedestal mounting has the rubber pad, leans on cabin or tower wall through the rubber pad, and when the staff climbed the cat ladder, strutting arrangement supports on tower wall or cabin wall, can prevent that the cat ladder from swaying and rock. In a word, the utility model discloses need not drill or weld on cabin or tower section of thick bamboo wall, when effectively protecting a tower section of thick bamboo and cabin, also solved the inconvenient drilling of cabin wall and welded problem and cat ladder free end and rock the problem.

Detailed Description

The present invention will be further described with reference to the following specific embodiments.

As shown in fig. 2 to 5, the novel ladder stand supporting device for a large wind generating set provided by this embodiment includes a base 1, a rubber pad 2, a nut 3, a gasket 4 and a screw rod 5, wherein the base 1 is designed to have a structure with a large end surface and a small end surface, the large end surface can increase the stress area, the small end surface can reduce the weight, the matching part of the large end surface of the base 1 and the rubber pad 2 is designed to be wedge-shaped, the rubber pad 2 can be prevented from slipping off, the rubber pad 2 is squeezed into the base 1 from the large end surface by external force to be clamped, and has a part extending out of the large end surface, and leans against the cabin 6 wall or the tower 7 wall of the wind generating set by the rubber pad 2, so as to reduce the damage of the supporting device to the paint and the metal structure on the cabin 6 wall or the tower 7 wall, one end of the screw rod 5 is welded on the small end surface of the base 1, and connected by welding process, so as to be safe and reliable, and the other end thereof is equipped with two nuts 3, the crawling ladder 8 can be firmly clamped by rotating the two nuts 3, and a gasket 4 is clamped between the nuts 3 and the crawling ladder 8. When the staff climbed cat ladder 8, strutting arrangement can support on 6 walls in cabin or tower section of thick bamboo 7 walls to prevent cat ladder 8 and sway and rock, as shown in fig. 5, adopted two strutting arrangement A, B, one of them strutting arrangement A supports on 6 walls in cabin, and another strutting arrangement B then supports on 7 walls of tower section of thick bamboo, through the multiple spot support like this, can reduce the cat ladder 8 atress position arm of force, and then reduce the moment of torsion, improve cat ladder 8 life-span, ensure climbing personnel safety.

The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that all the changes made according to the shape and principle of the present invention should be covered within the protection scope of the present invention.
