Abstract
The invention relates to a ladder for a wind power generation tower, and relates to the technical field of manufacturing of ladders in tower tubes. The ladder comprises a tower tube and a ladder body arranged in the tower tube, fixing feet are welded to the inner wall of the tower tube and divide the tower tube into a plurality of tower tube units, the fixing feet are connected with separation supporting layers used for distinguishing the tower tube units, the middle of each separation supporting layer is provided with a through hole allowing the ladder body to pass, and the ladder body is connected with the separation supporting layers. By means of the scheme, the ladder enables the structural strength of the whole power generation tower to be large and enables operators to climb conveniently.
Description
Technical field
The invention belongs to the manufacturing technology field of cat ladder in tower cylinder, particularly a kind of wind power generation stepped cat ladder.
Background technique
Existing cat ladder can affect the structural strength of whole power generation column when manufacturing, the less stable of the pedestal of whole power generation column can be made when being arranged on tower cylinder inner side surface, because the internal stress distribution of whole tower cylinder pedestal can be made when being welded on the side in tower cylinder uneven, easily produce fracture surface when natural disaster.And be unfavorable for the climbing of maintenance man.
Summary of the invention
The object of the invention is to provide one to make whole power generation tower structure intensity comparatively large, and the cat ladder of easy-to-operat personnel climbing.
Above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of wind power generation stepped cat ladder, comprise tower cylinder and be arranged on the cat ladder in described tower cylinder, described tower cylinder inwall is welded with fastening foot, and described tower cylinder is divided into some tower cylinder unit by described fastening foot; Described fastening foot is connected with the separation supporting layer distinguishing described tower cylinder unit; The through hole that described cat ladder is passed through is offered in the middle part of described separation supporting layer; Described cat ladder connects with the described supporting layer that is separated.
As preferably, described separation supporting layer comprises the main support rod welded with described fastening foot, and described main support rod arrangement is in " well " type.
As preferably, between described main support rod, be provided with the barrier supported.
As preferably, described tower cylinder unit described cat ladder when described tower cylinder end is fixed in described fastening foot.
As preferably, the described cat ladder being arranged on described tower cylinder end is provided with guard ring.
As preferably, described guard ring is interwoven by metallic threadlike material.
In sum, present invention achieves and make whole power generation tower structure intensity comparatively large, and the cat ladder of easy-to-operat personnel climbing.Tower cylinder inwall is welded with some fastening foot uniformly and can ensures that the internal stress distribution of whole tower cylinder is even, also ensure that structural strength and the working life of whole tower cylinder.The structure of " well " font can ensure the stability of whole column foot seat, and the through hole of centre can arrange cat ladder, and structure is simple and convenient.Arranging of barrier can make operator well keep in repair.Be in the cat ladder on tower cylinder top because the cross-section area on tower cylinder top is less, so can only be arranged on tower cylinder side, but the fastening foot of fixing cat ladder is still arranged on tower cylinder surrounding uniformly to ensure the structural strength of whole power generation column.Arranging of guard ring can protect maintenance man.
Accompanying drawing explanation
Fig. 1 is side view cutaway drawing of the present invention;
In Fig. 1,1-tower cylinder, 11-tower cylinder unit, 2-cat ladder, 21-guard ring, 3-fastening foot, 4-is separated supporting layer, 41-main support rod.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
A kind of wind power generation stepped cat ladder as shown in Figure 1, the cat ladder 2 comprising tower cylinder 1 and be arranged in tower cylinder 1, tower cylinder 1 inwall is welded with fastening foot 3, and tower cylinder 1 is divided into three tower cylinder unit 11 by fastening foot 3; Fastening foot 3 is connected with the separation supporting layer 4 distinguishing tower cylinder unit 11; Be separated in the middle part of supporting layer 4 and offer the through hole that cat ladder 2 is passed through; Cat ladder 2 be separated supporting layer 4 and weld.Tower cylinder unit 11 cat ladder 2 when tower cylinder 1 end is fixed in described fastening foot 3, and this section of cat ladder 2 is provided with guard ring 21, and guard ring 21 is interwoven by metallic threadlike material.
Be separated supporting layer 4 and comprise the main support rod 41 welded with fastening foot 3, main support rod 41 arranges in " well " type.The barrier supported is provided with between main support rod 41.
This specific embodiment is only explanation of the invention; it is not limitation of the present invention; those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this specification, as long as but be all subject to the protection of Patent Law in right of the present invention.
