Abstract
The utility model discloses a cable bridge rack, relating to cable laying equipment for erecting and protecting the cable, which is composed of a U-shaped main body and a cover plate. Strip shaped grooves, which are arranged lengthways in parallel, are installed on the U-shaped main body, and the long axis is vertical to the longitudinal axis of the main body while the grooves can be concave towards the inside of the U-shaped main body or can be convex towards the outside of the U-shaped main body. The grooves can increase the section modulus of the bridge and improve the strength of the bridge, and the utility model relates to the cable bridge rack with high intensity and low cost.
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 cable, 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, production cost 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 " frame, perhaps at " U " frame reinforcement 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 manufacturing 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 novel cable crane span structure.
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 parts, it is characterized in that on " U " shape main body, being provided with groove parallel along the longitudinal, groove is a strip groove, the major axis of groove is vertical with the longitudinal axis of main body, and groove is recessed to be protruded in " U " shape main body or outside " U " shape main body.By the section modulus that groove has increased crane span structure is set, improved the intensity of crane span structure.Groove described in the utility model forms with the compacting of " U " shape main body one.
The cross section of groove described in the utility model is circular arc, U-shaped, trapezoidal or herringbone.
The utility model is provided with groove parallel along the longitudinal in the bottom surface of " U " shape main body.
The utility model is provided with groove parallel along the longitudinal in the side of " U " shape main body.
The utility model is provided with groove parallel along the longitudinal simultaneously in the bottom surface and the side of " U " shape main body.
The utility model is provided with catching groove on " U " shape main body two sides, described catching groove is the triangle teeth groove, be provided with the triangle profile that interlocks with the main body catching groove in the inboard of crane span structure cover plate, the triangle catching groove takies under the condition of principal space in the minimizing of trying one's best, increased the contact area of profile and catching groove, feasible fastening is more firm, makes things convenient for profile to snap in the catching groove smoothly simultaneously.
The inside inflection in end of the utility model " U " shape main body two sides, form a flanging, flanging make " U " shape main body sharp cutting edge stash scratch workman's arm in can avoiding constructing.
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.

Below in conjunction with accompanying drawing the utility model is further specified.
Specific embodiment:
The main body 1 of the utility model cable testing bridge is " U " shape main body shown in accompanying drawing 1, accompanying drawing 2, on " U " shape main body cover plate is housed also, on the base plate of " U " shape main body and biside plate, be provided with the groove 2 that longitudinally equidistantly is arranged in parallel, groove is that two ends are semicircular strip groove, the major axis of strip groove is vertical with the longitudinal axis of main body, and groove is recessed in main body.The cross section of groove is a circular arc.The base plate of " U " shape main body and the groove on the biside plate all are arranged in parallel with equidistant from distance.Three grooves on " U " shape main body base plate and the biside plate relevant position are positioned on the same cross section of " U " shape main body.
The base plate of the utility model " U " shape main body can equate also can not wait with its length of groove on the side plate, decides on the model of crane span structure.
The main body 1 of the utility model cable testing bridge is " U " shape main body shown in accompanying drawing 3, accompanying drawing 4 and accompanying drawing 5, is provided with the groove 2 that longitudinally is arranged in parallel continuously on the base plate of " U " shape main body and biside plate, and the cross section of groove 2 is a herringbone.
The utility model has longitudinally elongated catching groove 3 on the top of " U " shape main body biside plate shown in accompanying drawing 6 and accompanying drawing 7, catching groove is the triangle teeth groove, the triangle teeth groove is formed by base 31 and rib 32, rib 32 is parallel with the bottom surface of main body, rib 32 ends extend upward, form a guide edge that in main body, tilts 4, the end of guide edge 4 horizontal-extending in main body, form top margin 5, the triangle teeth groove takies under the condition of principal space in the minimizing of trying one's best, increased the contact area of profile and catching groove, made that fastening is more firm.Hypotenuse 4 can snap in the catching groove cover plate more easily.
The end of " U " shape main body two sides is top margin 5 inside inflection, formation one flanging 7.Flanging make " U " shape main body sharp cutting edge stash scratch workman's arm in can avoiding constructing.
The utility model also is provided with groove parallel along the longitudinal at the end face of cable bridge entry board 6 shown in accompanying drawing 8 and accompanying drawing 9, and the structure of groove and arrangement mode are identical with groove on the main body.Be provided with the triangle tooth bar that interlocks with the main body catching groove in the inboard of cover plate, the triangle tooth bar that described triangle tooth bar also is made up of hypotenuse 61 and rib 62, its hypotenuse 61 of triangle tooth bar presses downward to along main body guide edge 4, buckles in the catching groove 3.
