Abstract
The utility model discloses a trough like corrosion-proof and shielding cable bridge, comprising a bridge cover and a bridge trough body. Shielding metal wire nets are arranged inside the bridge and the bridge trough body, and corrosion-proof layers are arranged outside the bridge cover and the bridge trough body. The metal wire nets arranged inside the bridge cover and the bridge trough body are connected with each other by metal hook locks, and each group of trough body is combined with each other through inner and outer connecting plates by bolts. The conductive resistance of the utility model is less than 0.09 omega, and the shielding and corrosion-proof properties of the utility model is favorable.
Description
The utility model relates to a kind of cable testing bridge, the anticorrosion shielded type cable crane span structure of particularly a kind of slot type.
At present, the shielded type cable crane span structure is mainly realized shielding with steel construction, outside zinc-plated or spraying corrosion resistant coating is realized anticorrosion, but its antiseptic effect is all undesirable, and when each crane span structure connects since anticorrosive coat very easily cause connect between the screen unreal, cause conducting resistance very big, and be difficult to reach shield effectiveness preferably.
The purpose of this utility model just is to overcome weak point of the prior art, provides a kind of simple in structure, antiseptic property, the anticorrosion shielded type cable crane span structure of the slot type that shield effectiveness is good.
The purpose of this utility model is to realize like this, it comprises: crane span structure lid, crane span structure cell body, establish the shielded metal silk screen in crane span structure lid, the crane span structure cell body, crane span structure lid, crane span structure cell body peripheral hardware anticorrosive coat, woven wire in crane span structure lid, the crane span structure cell body links together by the metal hook lock, and each organizes cell body by inside and outside connecting plate with bolt combination together.
The purpose of this utility model can realize that also the metal hook lock is shaped as J-shaped by following technical measures, and the connecting portion of interior connecting plate, crane span structure cell body is provided with woven wire.
Compared to existing technology, the utlity model has simple in structurely, antiseptic property, shield effectiveness are good, advantage such as easy to use.
