Abstract
The utility model belongs to the wire frame technical field and relates to an anti-interference bridge frame which is used for protecting or mounting optical cables, power cables or wires. The anti-interference bridge frame is characterized in that the anti-interference bridge frame comprises a bridge frame main body and a cover plate; three porous U-shaped steel bars are spliced parallelly so as to form the bridge frame main body; side plates of the U-shaped steel bar located at the middle of the bridge frame main body are separated from each other by 5 to 45 cm; side plates at the external sides of the U-shaped steel bars at two wings of the bridge frame main body are provided with bent edges which are bent inwards; the cover plate is a metal plate made of the same material with the bridge frame main body; the cover plate covers over the bridge frame main body; and the cover plate is fixed on the bridge frame main body through hasps. The anti-electromagnetic interference groove type closed bridge frame of the utility model is of a three-grid structure, and the U-shaped steel bar arranged at the middle can shield electromagnetic radiation and dissipate heat. According to the anti-electromagnetic interference groove type closed bridge frame, a horizontal suspending supporting arm installation mode and an adjustable mounting mode can be adopted, and at the same time, a ground direct laying mode can be adopted. The anti-electromagnetic interference groove type closed bridge frame can bear heavy load, and has concise appearance.
Description
Technical field
The utility model relates to coil holder technical field, is specially a kind of airtight crane span structure of anti-electromagnetic interference grooved for the protection of optical cable, telecommunication cable or power cable are installed.
Background technology
Conventional type cable testing bridge is an auxiliary equipment of laying protection cable, is applicable to lay the control cables of computer cable, telecommunication cable, thermocouple cable and other Highly Sensitive Systems etc.But in actual job environment strong and weak electricity electric wire cable intersect frequently, relatively intensive, but cannot solve the problem that closely causes mutually electromagnetic interference between cabling.
Summary of the invention
In order to solve existing cable crane span structure, there is the problem of poor anti jamming capability, the utility model proposes the airtight crane span structure of a kind of anti-electromagnetic interference grooved.
The airtight crane span structure of anti-electromagnetic interference grooved of the present utility model, it is characterized in that comprising crane span structure main body and cover plate, crane span structure main body is U-shaped steel, on base plate in crane span structure main body, be vertically installed with two dividing plates, the side plate of crane span structure main body and dividing plate top are provided with the bending edge bending inwards, and crane span structure main body side plate two ends are provided with U-shaped hole; Crane span structure main body top arranges cover plate, and cover plate adopts band steel or U-shaped steel, and cover plate is fixed in crane span structure main body by hasp, makes crane span structure in complete air-tight state,
Two described clapboard spacings are specially 5-45 centimetre.Clapboard spacing determines according to the factors such as electric current, voltage of putting into anti-interference crane span structure.5 centimetres for clapboard spacing be jamproof minimum range; Although adopt larger baffle interval distance anti-jamming effectiveness better, area occupied causes more greatly impracticable.
Further, the airtight crane span structure of described anti-electromagnetic interference grooved adopts metallic plate to process.
The size of the airtight crane span structure of anti-electromagnetic interference grooved is determined according to machine room actual conditions, is utilized if desired connector by U-shaped hole, several anti-interference crane span structures to be linked together.During operation, respectively strong and weak electricity cable is placed in to crane span structure main body both wings; Can to the specification requirement of water proof and dust proof, install cover plate additional according to operating environment.
The airtight crane span structure of this anti-electromagnetic interference grooved can adopt single or multiple lift to install, and need not punch, need not specific purpose tool, can installation of ceiling, and ground supports is installed, and also can be used as cat ladder and uses.
The features such as the airtight crane span structure of this anti-electromagnetic interference grooved has the built on stilts corbel type mounting means of level, also can adopt and adjust dress formula mounting means, can adopt the straight application mode in ground simultaneously, has supporting power large, and appearance looks elegant is succinct.
Accompanying drawing explanation
Fig. 1 is the sectional view of the airtight crane span structure of the anti-electromagnetic interference grooved of the utility model.
Wherein, crane span structure main body 1, cover plate 2, hasp 3.
Embodiment
