Abstract
The utility model provides a ladder edge of a ladder frame specially used for nuclear power. The ladder edge comprises a ladder edge body, wherein a longitudinal groove is arranged on the side surface of the ladder edge body. As the longitudinal groove is arranged on the side surface of the ladder edge body, the strength and the rigidity of the ladder edge are improved, so that the ladder edge with the shape has the characteristics of high loading capacity and high shock strength, the overall strength of the ladder frame is improved, the bearing capacity is high, the protection level of the ladder frame reaches IP66, and the safety performance of the ladder frame is greatly improved; and the ladder edge has a simple structure and is convenient to process.
Description
Technical field
The utility model relates to a kind of terraced limit of crane span structure, belongs to the technical field of cable testing bridge parts.
Background technique
Cable testing bridge is extensive in sector applications such as oil, chemical industry, electric power, light industry, telecommunications, is mainly used in laying of empty power cable, actuating cable, illuminating line, telecommunication cable, has relatively high expectations for intensity, the bearing capacity of crane span structure.Crane span structure comprises terraced limit, terraced Guang, and described terraced limit and described terraced Guang are fixed into one, adopts the sectional shape that changes cable bridge ladder limit section bar usually, improves intensity, bearing capacity and the bending resistance of crane span structure.
The terraced limit of traditional cable crane span structure is to adopt the compacting of individual layer steel plate to form, and the cross section of crane span structure ladder limit section bar mostly is] shape, but the crane span structure intensity of this structure is low, bearing capacity is relatively poor; In order to improve the intensity of crane span structure, in recent years, adopt the special-shaped aluminum-magnesium alloy material of I-shaped to make on the terraced limit of crane span structure, and the corresponding convolution in the both sides, top of I-shaped become two " L " shape sulculuses, the corresponding convolution in following both sides becomes " U " shape sulculus, support concavo-convex line in the I-shaped vertical surface substantially horizontal two wave-wave types that are made into, make whole cross section change wave mode into by straight line, the crane span structure section bar of this structure, improved the intensity of crane span structure, bearing capacity and resistance to tension, but the crane span structure profile structure complexity of this structure, process loaded down with trivial details and waste material, increased the cost of production of enterprise greatly.
The content of model utility
Technical problem to be solved in the utility model provides the terraced limit of a kind of intensity height, bridge frame dedicated for nuclear power simple in structure, and the bearing capacity of crane span structure has been improved on this ladder limit greatly.
In order to solve the problems of the technologies described above, the terraced limit of a kind of bridge frame dedicated for nuclear power of the utility model comprises terraced limit body, and wherein, the side of described terraced limit body is provided with longitudinal fluting.
The terraced limit of above-mentioned a kind of bridge frame dedicated for nuclear power, wherein, described terraced limit body is a L shaped plate body, body upper end in described terraced limit is a hook end.
The utility model can be realized following beneficial effect:
1, because the side of described terraced limit body is provided with longitudinal fluting, intensity, the rigidity on terraced limit have been improved, make the terraced limit of this shape have the advantages that load-carrying ability is strong, shock strength is high, thereby the bulk strength and the bearing capacity that have improved crane span structure are strong, make the security level of crane span structure reach IP66, improved the Safety performance of crane span structure greatly; And the utility model is simple in structure, easy to process.
2, because described terraced limit body is a L shaped plate body, body upper end in described terraced limit is a hook end, and when being connected with the terraced Guang of crane span structure, the transverse slat of body lower end, terraced limit wraps in below the terraced Guang, can play certain picking-up effect to terraced Guang, makes the connection of crane span structure more firm; The hook end of upper end can tightly block the cover plate of crane span structure, plays certain dustproof effect, can protect cable, therefore, improved whole crane span structure Safety performance, prolonged working life of cable.

Fig. 1 is a structural representation of the present utility model
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, in order to solve the problems of the technologies described above the terraced limit of a kind of bridge frame dedicated for nuclear power of the utility model, comprise terraced limit body 1, wherein, the side of described terraced limit body 1 is provided with longitudinal fluting 2, and the shape of longitudinal fluting 2 is unrestricted, can be square groove, also can be the groove of circular arc, and the quantity of longitudinal fluting 2 is unrestricted, can designs according to actual needs, can be one, also can be a plurality of; Because the side of described terraced limit body 1 is provided with longitudinal fluting 2, intensity, the rigidity on terraced limit have been improved, make the terraced limit of this shape have the advantages that load-carrying ability is strong, shock strength is high, thereby the bulk strength and the bearing capacity that have improved crane span structure are strong, make the security level of crane span structure reach IP66, improved the Safety performance of crane span structure greatly; And the utility model is simple in structure, easy to process.
The shape of ladder limit body is unrestricted, can be the bar shaped tabular component, also can be] the shape member, in the present embodiment,, preferably described terraced limit body 1 is designed to a L shaped plate body in order to improve the Safety performance of crane span structure integral body, body 1 upper end, described terraced limit is a hook end 11.
In sum, the utility model compared with prior art has the intensity height, advantage of simple structure, and use of the present utility model has improved the bearing capacity of crane span structure integral body, anti-seismic performance greatly.
Here description of the invention and application is illustrative, is not to want that therefore, the present invention is not subjected to the restriction of present embodiment with scope restriction of the present invention in the above-described embodiments, and the technological scheme that any employing equivalence replacement obtains is all in the scope of protection of the invention.
Claims (2)
1. the terraced limit of a bridge frame dedicated for nuclear power comprises terraced limit body, it is characterized in that, the side of described terraced limit body is provided with longitudinal fluting.
2. a kind of terraced limit of bridge frame dedicated for nuclear power according to claim 1 is characterized in that described terraced limit body is a L shaped plate body, and body upper end in described terraced limit is a hook end.
