Abstract
The utility model relates to for field of power distribution, a kind of ladder-type bridge frame specifically, comprise biside plate and the several strut rails being connected biside plate lower end, the cross section of strut rail described in each is the narrow isosceles trapezoid in wide lower end, upper end, strut rail described in each is arranged at intervals with along its length the skewed slot that the little lower ending opening of several upper end open is large.Strut rail is designed to isosceles trapezoidal structure by the utility model, and processing is simple on the one hand, and rainwater can be made on the other hand to flow out along trapezoidal inclined-plane, and ponding can not remain on crosspiece; Meanwhile, cable also can directly snap in it by the skewed slot that crosspiece is arranged, and without the need to using wire clamp etc. to limit cable, it is easy for installation.
Description
Technical field
The utility model relates to for field of power distribution, is specially a kind of ladder-type bridge frame.
Background technology
In general, crane span structure is as the device being used for fixed cable for field of power distribution, and its application widely.In the operation process of the circuit such as cable laying, netting twine, often can, because the specification of lay-up, the difference of size, the crane span structure of different size be adopted to meet the demand of laying; Meanwhile, in order to improve bulk strength, making crane span structure can be used in the more severe place of environment, having made a lot of improvement for its structure.But, due to size being restricted, add the finite thickness of metallic plate, at some for installation requirement and the higher occasion of dimensional requirement, be difficult to meet in-site installation requirement, and existing ladder-type bridge frame anti-ponding ability is poor, the needs of the adverse circumstances such as humidity and strenuous vibration that ocean engineering has cannot be adapted to.
Utility model content
For above-mentioned technical problem, the utility model provides the ladder-type bridge frame that a kind of ponding ability easy for installation, anti-is stronger.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of ladder-type bridge frame, comprise biside plate and the several strut rails being connected biside plate lower end, the cross section of strut rail described in each is the narrow isosceles trapezoid in wide lower end, upper end, strut rail described in each is arranged at intervals with along its length the skewed slot that the little lower ending opening of several upper end open is large.
As preferably, side plate described in each forms arc crimp laterally, and crimp has opened osculum.
As preferably, side plate described in each is opened several installing hole.
As can be known from the above technical solutions, strut rail is designed to isosceles trapezoidal structure by the utility model, and processing is simple on the one hand, and rainwater can be made on the other hand to flow out along trapezoidal inclined-plane, and ponding can not remain on crosspiece; Meanwhile, cable also can directly snap in it by the skewed slot that crosspiece is arranged, and without the need to using wire clamp etc. to limit cable, it is easy for installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of optimal way of the utility model.
Fig. 2 is the side schematic view of Fig. 1.
Embodiment
Below in conjunction with Fig. 1, Fig. 2, the utility model is further described:
A kind of ladder-type bridge frame, it comprises biside plate 1 and the several strut rails 2 being connected biside plate lower end, and strut rail can be fixed with plate-side plate welding, and the cross section of strut rail described in each is the narrow isosceles trapezoid in wide lower end, upper end, and ponding can not be remained on strut rail, improves water resistance; Strut rail 2 described in each is arranged at intervals with along its length the skewed slot 21 that the little lower ending opening of several upper end open is large; Skewed slot is adopted to limit cable, easy for installation, avoid using wire clamp, and the little lower ending opening of skewed slot upper end open is large, makes cable not easily depart from skewed slot, when mounted, only cable need be pressed into skewed slot, light, quick.
In implementation process, described in each, side plate 1 forms arc crimp 11 laterally, crimp has been opened osculum 12; The radian of arcuate structure should be greater than 270 degree and be less than 360 degree, can prevent from like this scratching cable, and can ensure that ponding is discharged from osculum; Side plate described in each is opened several installing hole 13, can ensure that crane span structure all has the function that is linked and packed in any position, also made crane span structure have more good thermal diffusivity and windproof simultaneously.
Above-mentioned execution mode is only for illustration of the utility model, and be not to restriction of the present utility model, the those of ordinary skill of relevant technical field, when not departing from the utility model spirit and scope, can also make various change and modification, therefore all equivalent technical schemes also should belong to category of the present utility model.
Claims (3)
1. a ladder-type bridge frame, comprise biside plate and the several strut rails being connected biside plate lower end, it is characterized in that: the cross section of strut rail described in each is the narrow isosceles trapezoid in wide lower end, upper end, strut rail described in each is arranged at intervals with along its length the skewed slot that the little lower ending opening of several upper end open is large.
2. ladder-type bridge frame as claimed in claim 1, is characterized in that: described in each, side plate upper end forms arc crimp laterally, and crimp has opened osculum.
3. ladder-type bridge frame as claimed in claim 1, is characterized in that: side plate described in each has been opened several installing hole.
