Abstract
The utility model discloses a cable bridge, characterized by, including crane span structure main part and crane span structure apron, crane span structure main part and crane span structure apron are pegged graft each other, the crane span structure main part includes crane span structure bottom plate and crane span structure curb plate, crane span structure bottom plate and crane span structure curb plate all are provided with the strengthening rib, crane span structure bottom plate and crane span structure apron are provided with the thermal energy portion of meeting, a cable bridge passes through meet thermal energy portion at heat effect inflation rapidly down, foaming and with the bleeder vent shutoff, play back -fire relief isolation effect, a requirement has effectively prevented thermal conduction that cable bridge passes through the flame retardant paint layer, has improved cable bridge's fire resistance greatly, and when the conflagration took place, it was long to maintain cable operating time, can guarantee the emergency requirement, reduces the loss that the conflagration caused, satisfy in electric the fire -protection rating.
Description
Technical field
This utility model 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.
Utility model content
The purpose of this utility model is 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.
The technical solution of the utility model 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 this utility model is reached: a kind of cable testing bridge described in the utility model 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 structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model bridge cover plate.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model 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 preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvement and deformation, these improve and deformation also should be regarded as protection domain of the present utility model.
