Abstract
The utility model relates to a cable bridge frame, which is a cable-laying device for erecting and protecting cables. The utility model is composed of a U-shaped main body and a cover plate, wherein the top of the U-shaoed main body is covered by the cover plate, the bottom surface of the U-shaped main body is provided with grooves arranged in parallel with the length direction of the main body, the bottom surfaces of the grooves stretch upwards to form one or more than one protrusions and the top surfaces of the protrusions are provided with openings. By installing grooves on the bottom surface of the U-shaped main body and the protrusions on the grooves, the bending resistant modulus of the U-shaped main body of the bridge frame can be increased, and by arranging openings on the protrusions, the weight of the bridge frame is reduced. The weight of the bridge frame is reduced by the utility model, and meanwhile, the strength of the bridge frameis increased.
Description
Technical field:
The utility model cable testing bridge relates to a kind of cable-laying gear that is used to set up and protect elastic cable paper, particularly relates to a kind of intensity height, cable testing bridge that cost is low.
Technical background:
Existing " U " cable testing bridge is for guaranteeing its bearing capacity, usually use thicker steel to process, therefore the crane span structure weight of producing is bigger, transportation, cost of production is higher, labor strength is big during installation, heavy phenomenon in use also appears pressing easily, be head it off, occurred that perforate reduces crane span structure weight on " U " shape frame, perhaps at " U " shape frame stiffening rib is set, the corresponding crane span structure that reduces thickness of steel product is though this kind crane span structure corresponding having reduced " U " frame weight under the condition of proof strength, but it is complicated that working process becomes, and fail fundamentally to reduce the weight of crane span structure.
Summary of the invention:
For avoiding the deficiencies in the prior art part the utility model that a kind of intensity height, in light weight is provided, process simple cable testing bridge.
The utility model cable testing bridge is realized by following technical measures: it is made up of " U " shape main body and cover plate two-part, cover plate covers at " U " shape main body top, bottom surface in " U " shape main body is provided with the groove that is arranged in parallel along the principal length direction, groove floor upwards stretches, form one or more projection, the utility model uses thin board making to form, and the projection in groove and the groove forms with the compacting of " U " shape main body one.The utility model can increase the composite bending modulus of crane span structure " U " shape main body by groove being set and projection is set in " U " shape main body bottom surface in groove, improved the intensity of crane span structure.
The utility model is provided with opening at the end face of projection, and opening is an opening circular, square or oval, long waist shaped.By the weight that opening can alleviate crane span structure is set, also can play draught effect.
The utility model is provided with one or more opening at the end face of projection.
Groove described in the utility model is located at main body inner bottom surface or main body outer bottom.
The height of projection described in the utility model is less than or equal to the degree of depth of groove.
More than one projection described in the utility model evenly distributes along the groove major axis.
The cross section of groove described in the utility model is circular arc, U-shaped or trapezoidal.
The cross section of projection described in the utility model is circular arc, the U-shaped or trapezoidal of end face opening.
The shape of projection described in the utility model is identical with the shape of groove.
The utility model is provided with the groove that is arranged in parallel along the principal length direction in the side of " U " shape main body.Groove is located at main body inner side surface or main body outer side surface.
The utility model is a kind of in light weight, cable testing bridge that intensity is high.It also has, and cost is low, the processing characteristic of simple.
Description of drawings:
Accompanying drawing 1 is the utility model " U " shape main body stereogram.
Accompanying drawing 2 is the utility model " U " shape main body worm's eye view.
Accompanying drawing 3 is the utility model accompanying drawing 2A-A sectional view.
Below in conjunction with accompanying drawing the utility model is further specified.
Specific embodiment:
As accompanying drawing 1, shown in accompanying drawing 2 and the accompanying drawing 3, the main body 1 of the utility model cable testing bridge is " U " shape main body, on " U " shape main body cover plate is housed also, outer bottom in " U " shape main body is provided with the groove 2 that equidistantly is arranged in parallel along the principal length direction, the cross section of groove is trapezoidal, be provided with three projectioies 3 in the groove, projection is upwards to be stretched by the bottom surface of groove to form, three projectioies evenly distribute along the length direction of groove, the profile of projection is a long waist shaped, the cross section of projection is the trapezoid cross section, on the end face of projection, be located at the long waist shaped opening, the height of projection is less than or equal to the degree of depth of groove, and the projection during making in groove and the groove forms with the compacting of " U " shape main body one.Two outer side surfaces in " U " shape main body are provided with groove 5, and the bottom surface of groove has through hole 6.
