Description
Technical field
The invention belongs to cable testing bridge, particularly relate to double ladder limits big span steel cable bridge.
Background technology
Cable testing bridge is divided into slot type, pellet type and the structure such as ladder-type, grid type, by support, trailing arm and installation annex etc.
Composition.Step type cable bridge frame has lightweight, low cost, moulding does not have, easy for installation, heat radiation, the ventilative advantage such as good.He fits
It for being typically relatively large in diameter laying of cable, is suitable for laying of high and low pressure power cable.Tray type cable bridge be oil,
The most widely used one of aspect such as chemical industry, light industry, telecommunication.It has lightweight, load is big, handsome in appearance, simple in construction, peace
The advantages such as dress is convenient.It is i.e. applicable to the installation of power cable, is also suitable for controlling laying of cable.Channel-type cable bridge is one
Plant Totally-enclosed-type cable testing bridge.It is best suited for laying computer cable, communication cable, thermocouple cable and other highly sensitive systems
The control cable etc. of system.Its shielding to control cable disturbs and in heavy corrosion, the protection of environmental cable has preferable effect.
Ladder-type, pellet type, channel-type cable bridge each pluses and minuses: ladder-type bus bar installation casing has a good performance of ventilating, not dust-proof,
Not anti-tampering.Slot type, pellet type bus bar installation casing have performance dust-proof, anti-tampering.
Current large span cable bridge rack is usually and is assembled by pulling and extruding glass fiber section bar, it is adaptable to power cable, control
Cable, light conduits and accessory etc..Compared with iron crane span structure, there is length in service life (be typically designed life-span be 20 years), peace
(proportion is only the 1/4 of carbon steel, and without getting angry in construction, single crane span structure length is up to 8 meters, even more for dress convenience and low cost
Long), cutting is convenient, be not required to the superiority such as maintenance, but cost is very high, and price is 3 times of steel cable bridge.
Content of the invention
It is an object of the invention to: proposition one is easy for installation, structure is reliable, stress performance is excellent, and cost significantly drops
Low big span steel cable bridge.
The object of the invention is realized by following technical proposals:

Offering the reserved opening allowing that trough type bridge frame passes through in crossbeam, two adjacent sections trough type bridge frame connecting portion arranges this reserved opening
In, use steel plate to expose as leveling pad and two ends bottom connecting portion, and in addition anti-skidding crab-bolt is fixed connection and guaranteed surely
Fixed, connecting portion connects piece also by crane span structure and connects grounding copper lenticular wire and shelter post ground connection；
Trough type bridge frame includes cell body and the cover plate of steel, cell body and cover plate by welding cover plate pintle hook lock buckle-type thereon
Fixed closed, the cavity closed between cell body and cover plate is the passage that current supply cable extends；Two cell walls at cell body be respectively equipped with
Cell wall hollow circular-tube structure that is one-body molded and that extend longitudinally with cell wall, the bottom land at cell body also is provided with laterally extending some
The hollow circular-tube structure that parallel interval is arranged.
Alternatively, the reserved opening in each shelter structural beams is positioned on unified absolute altitude and axis.
Alternatively, the hollow circular-tube structure on cell wall is two, and the hollow circular-tube structure on bottom land is equidistantly uniformly divided
Cloth.
Alternatively, reserved opening size than trough type bridge frame wide high each big 20mm.
The main scheme of the aforementioned present invention and each further selection scheme thereof can be this with independent assortment to form multiple scheme
Invention can use and claimed scheme；And the present invention, (each non conflicting selection) select between and and other select between
Also can be with independent assortment.Those skilled in the art can understand have according to prior art and common knowledge after understanding the present invention program
Multiple combination, is the claimed technical scheme of the present invention, does not do at this exhaustive.
Beneficial effects of the present invention: easy for installation, the big span cable bridge of relatively current conventional pulling and extruding glass fiber section bar
Frame, structure is more reliable, stress performance is more excellent, and cost is greatly reduced.

Detailed description of the invention
Following non-limiting examples is used for the present invention is described.
With reference to shown in Fig. 1-4, a kind of station shelter large span crane span structure, including be arranged in below shelter 1 with shelter 1
The crane span structure longitudinally extending, crane span structure is formed by connecting by more piece trough type bridge frame 2, and often saving trough type bridge frame 2 length is 9 meters with shelter span
～12 meters, in shelter 1 structural beams 3, offer the reserved opening 4 allowing that trough type bridge frame 2 passes through, two adjacent sections trough type bridge frame 2
Connecting portion arranges in this reserved opening 4, uses steel plate 5 to expose as leveling pad and two ends bottom connecting portion, and in addition
Anti-skidding crab-bolt 6 is fixed connection and is guaranteed stable, and connecting portion connects piece 7 also by crane span structure and connects grounding copper lenticular wire 8 and shelter post 9
Ground connection；
With reference to Fig. 1, shown in 4, trough type bridge frame 2 includes cell body and the cover plate of steel, cell body and cover plate by welding thereon
Cover plate pintle hook lock buckle-type fixed closed, between cell body and cover plate close cavity be current supply cable extend passage；At cell body
Two cell walls 21 are respectively equipped with hollow circular-tube structure 22 that is one-body molded with cell wall 21 and that extend longitudinally with cell wall 21, at cell body
Bottom land 23 also is provided with the hollow circular-tube structure 22 that laterally extending some parallel interval are arranged.Sky as preferably, on cell wall 21
Heart circular tube structure 22 is two, and the hollow circular-tube structure 22 on bottom land 23 is equidistantly uniformly distributed.
Embodiment 1:
As example, certain engineering uses trough type bridge frame width 150mm, high 100mm, and often saving length is 9 meters with shelter span
～12 meters.In the construction of large span crane span structure, it is desirable to the reserved opening size that shelter wears Liang Chu is unified for wide 170mm, height
Unnecessary gap after crane span structure installation, then is blocked by 120mm；And it is straight in order to ensure that crane span structure is installed, in construction
Before need unwrapping wire to confirm all reserved openings all on unified absolute altitude and axis.The length of large span crane span structure is according to shelter axis of a cylinder
