Abstract
The utility model relates to a cable bridge rack which is characterized in that a die which is especially processed and manufactured is used for processing a sliver-shaped ladder stick of which the external shape is an enclosed sliver-shaped tubular structure composed of a circular arc or a plurality of circular arcs. A supporting wall plate is arranged in the sliver-shaped ladder stick, and the centre of the supporting wall plate is provided with a fastening connecting position. The cross section shape of the conventional rectangular ladder stick of an original cable bridge rack is altered by the utility model to cause the cross section shape to become an upward surface or a plurality of surfaces to form a circular arc-shaped structure to reduce the friction damage of cables in the cable bridge rack and edge angles of the rectangular ladder stick in the process of laying construction. A local ageing phenomenon of the cables generated by the cables contacting the edge angles of the ladder stick of the cable bridge rack for a long term is lowered, and the external shape is more beautiful.
Description
Technical field
The utility model relates to cable testing bridge, refers in particular to the ladder-type aluminium alloy cable crane span structure circular arc ladder rod that can significantly reduce the wearing and tearing between the cable and cable testing bridge in the cable discharging work progress.
Background technology
The ladder-type cable testing bridge is that the employing cross section is the terraced rod of rectangle before this mostly, no matter is materials such as aluminium alloy, steel, engineering plastics, is not always the case.Rectangle ladder rod makes cable in discharge process, produce very big friction damage with the edge corner angle of terraced rod, cable is long-term in addition lays on the rectangle ladder rod that is shelved on corner angle, can make the local fatigue aging that produces of cable in the course of time, causes potential safety hazard to a certain extent.
Summary of the invention
The purpose of this utility model is improved at shortcoming that exists in the background technology and problem, and a kind of cable testing bridge circular arc ladder rod is provided.
The technical scheme that realizes the utility model purpose is such: the mould that adopts special processing and fabricating, process strip ladder rod, ladder rod profile is the strip tubular structure of the sealing of a circular arc or multiaspect circular arc composition, be provided with the support wallboard in the ladder rod, the centre of supporting wallboard is provided with and is fastenedly connected the position.
The utility model has changed the rectangle ladder rod cross section moulding of prior cable crane span structure routine, making it to become upwards, one or more surfaces forms arc-shaped structure, damage with the friction of rectangle ladder rod corner angle in the laying construction process to reduce cable in the cable testing bridge, reduce cable because of contacting the local ageing phenomenon that produces with the corner angle of cable bridge ladder rod for a long time, and make its profile more attractive in appearance, the construction and installation cable is more convenient.
Technology of the present utility model is suitable for aluminium alloy, almag, steel equally, or the material of other multiple mischmetal carries out processing and manufacturing, also can be used for high-strength engineering plastic materials and carries out processing and manufacturing.
Cross section structure moulding of the present utility model can be carried out some on this basis and develop, other the Mechanical Builds of deriving.
Description of drawings

Accompanying drawing 2 is Fig. 1 end face enlarged drawings
Embodiment
By Fig. 1,2 as can be known, the utility model ladder rod profile is the strip tubular structure of the sealing of a circular arc or multiaspect circular arc composition, is provided with the support wallboard in the terraced rod, and the centre of supporting wallboard is provided with the securing member link position.
Cable testing bridge circular arc described in the utility model ladder rod is characterized in that described support wallboard (4) can horizontal or vertically set up, also can be vertically and level respectively be built up in the terraced rod.Described securing member link position can be the through hole cylinder (5) of a band opening (6).Riveted joint stays the position that holding screw is screwed into during as terraced rod combine and assemble crane span structure from now on.Described terraced rod profile can with above be made as arc surface (1), arc surface (1) is a plane with two vertical edges (2) for arc transition is connected bottom surface (3).Mechanical Builds of the present utility model can also be processed into side and base plate the geometric modeling structure that has waveform, arc, trapezoidal or convex line etc.Cross section structure moulding of the present utility model can be carried out some on this basis and develop, and other the Mechanical Builds of deriving all belongs to protection range of the present utility model.Technology of the present utility model is suitable for aluminium alloy, almag, steel equally, or the material of other multiple mischmetal carries out processing and manufacturing, also can be used for high-strength engineering plastic materials and carries out processing and manufacturing.The utility model has changed the rectangle ladder rod cross section moulding of prior cable crane span structure routine, making it to become upwards, one or more surfaces forms arc-shaped structure, damage with the friction of rectangle ladder rod corner angle in the laying construction process to reduce cable in the cable testing bridge, reduce cable because of contacting the local ageing phenomenon that produces with the corner angle of cable bridge ladder rod for a long time, and make its profile more attractive in appearance, the construction and installation cable is more convenient.
