Abstract
The invention discloses a cable bridge, and the cable bridge is characterized in that the cable bridge comprises a bridge main body and a bridge cover plate; the bridge main body and the bridge cover plate are in plugging connection with each other; the bridge main body comprises a bridge bottom plate and bridge side plates; the bridge bottom plate and the bridge side plates are respectively provided with reinforcing ribs, and are also provided with thermal expansion parts. The thermal expansion parts are quickly expanded and foamed to block air holes under the action of heat, and achieve the fire retardance and isolation. The cable bridge greatly improves the fireproof performance through a fireproof paint layer, enables a cable to work for a long time during fire, can meet the demands of emergency, reduces the loss caused by fire, meets the requirements for a fire protection level electrically, and effectively blocks the transfer of heat.
Description
Technical field
The present invention relates to a kind of erection and the cable laying device of protection cable, more particularly to a kind of intensity cable testing bridge high, multi-functional.
Background technology
Cable testing bridge is extensive in sector applications such as oil, chemical industry, electric power, light industry, telecommunications, was mainly used in empty power cable, controls cable, illuminating line, the laying of telecommunication cable.The obturator that the cable testing bridge that people commonly use at present is made up of main body and cover plate grafting, owing to the heat produced when cable works long hours can not distribute in time, reduces the current-carrying capacity of cable to a great extent, and is susceptible to fire.
Summary of the invention
It is an object of the invention to overcome the deficiency of above-mentioned prior art, it is provided that a kind of intensity height, convenient transportation, a kind of cable testing bridge that using effect is good.
Technical scheme is as follows: a kind of cable testing bridge, it is characterized in that, including crane span structure main body and bridge cover plate, described crane span structure main body and bridge cover plate are mutually inserted, and described crane span structure main body includes that crane span structure base plate and crane span structure side plate, described crane span structure base plate and crane span structure side plate are provided with reinforcement, described crane span structure base plate and bridge cover plate are provided with heat bulge, described heat bulge expands rapidly under heat effect, foams and is blocked by air-vent, plays back-fire relief isolation effect.
Further, described heat bulge is to be made up of expansible graphite or made coating by the goods comprising expansible graphite.Expansible graphite has the characteristic of heat rapid expanding, can expand rapidly several times to tens times when meeting fire, can expand rapidly formation refuge floor, stops propagation of flame.
Further, described reinforcement cross section is trapezoidal or oval, the most internally protrudes, and by the setting of reinforcement, can strengthen intensity and bearing capacity that cable is built bridge.
Further, the outer surface of described crane span structure base plate, crane span structure side plate and bridge cover plate all scribbles fire prevention enamelled coating.By fire prevention enamelled coating, substantially increase the fire resistance of cable testing bridge, when fire occurs, maintain cable longevity of service, it is ensured that emergency requirement, reduce the loss that fire causes, meet the requirement to fire-protection rating in electrically, effectively prevent the conduction of heat.
Further, described crane span structure base plate and crane span structure side plate are provided with some vents, it is simple to ventilate.
Further, described vent is generally circular in shape or rectangle.
The beneficial effect that the present invention is reached: a kind of cable testing bridge of the present invention is expanded rapidly under heat effect by described heat bulge, foams and is blocked by air-vent, plays back-fire relief isolation effect；Described a kind of cable testing bridge, by fire prevention enamelled coating, substantially increases the fire resistance of cable testing bridge, when fire occurs, maintain cable longevity of service, it is ensured that emergency requirement, reduce the loss that fire causes, meet the requirement to fire-protection rating in electrically, effectively prevent the conduction of heat.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of bridge cover plate of the present invention.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
nullAs shown in Figure 1，A kind of cable testing bridge，It is characterized in that，Including crane span structure main body and bridge cover plate 2,Described crane span structure main body and bridge cover plate 2 are mutually inserted，Described crane span structure main body includes crane span structure base plate 3 and crane span structure side plate 1，Described crane span structure base plate 3 and crane span structure side plate 1 are provided with reinforcement 4，Described crane span structure base plate 3 and bridge cover plate 2 are provided with heat bulge，Described heat bulge 5 is the coating be made up of expansible graphite or be made up of the goods comprising expansible graphite，Described reinforcement cross section is trapezoidal，The most internally protrude，By the setting of reinforcement，Intensity and bearing capacity that cable is built bridge can be strengthened，Described crane span structure base plate、The outer surface of crane span structure side plate and bridge cover plate all scribbles fire prevention enamelled coating 6，Described crane span structure base plate and crane span structure side plate are provided with some vents，It is easy to ventilate，Described vent is generally circular in shape.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, on the premise of without departing from the technology of the present invention principle; can also make some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention.
