Description

Cable testing bridge

Technical field

The utility model relates to a kind of crane span structure, relates in particular to a kind of cable testing bridge that the cable aspect is installed in engineering construction that is used in.

Background technique

Along with China's development of economic construction, cable testing bridge is widely used, it makes the equipment of electric wire, cable, optical cable possess standardization, seriation, generalization level, aspect the installation of use crane span structure, existing technology uses fabricated metals and glass fiber reinforced plastics product to make mostly, its Heavy Weight, easily get rusty, the cost height, aspect construction, the joint of each crane span structure all is to link to each other by screw with iron plate, like this in installation process and complicated, the mounting cost height is not easy to the maintenance in later stage.

The model utility content

For addressing the above problem, the utility model provide a kind of in light weight, the life-span long, with low cost, non-conductive, cable testing bridge simple, easy-maintaining is installed.

In order to solve the problems of the technologies described above, the utility model is to realize like this.

The employed material of the utility model all is that the PVC material is made, form by straight type crane span structure and connection fittings, described straight type crane span structure is made of rectangular or foursquare base plate and panel, and two slots are arranged on the described base plate, and described panel has two inserted sheets of corresponding backplane slot.

Inserted sheet on the described panel can be in the slot slides within the effect of external force.

There is draw-in groove described slot inside, on the described inserted sheet card article is arranged, and card article just in time is placed in draw-in groove inside, make that the inserted sheet on the panel can be from landing on the slot, thereby panel can not separate with base plate.

Described connection fittings comprise that two lead to and connect accessory, threeway connection fittings, four-way connection fittings.

The turning of described connection fittings all is provided with a buffering angle, mainly is the effect of playing the buffering of turning in the process that electric wire passes.

The big circle of the connection mouth of the straight type crane span structure of the relative aperture of each connection mouth in the described connection fittings, guarantee that straight type crane span structure just in time interts in connection fittings inside, in connection procedure, connection fittings inside is applied glue, then straight type crane span structure is inserted the connection mouth of connection fittings, make connection fittings fixedly connected with straight type crane span structure.

Described connection fittings all are provided with notch, the installation that guarantees electric wire with lay.

Described panel, can cover by the notch that will connect on the crane span structure that slides with after connection fittings link to each other at straight type crane span structure, and the assurance electric wire all is in sealing state.

The utility model compared with prior art has following remarkable advantages and beneficial effect:

1, in light weight, be easy to install and transportation.

2, adopt the PVC material to make, cheap, non-conductive,

3, for ease of maintenaince.

4, long service life.

5, linkage structure is simple.
