Abstract

The utility model relates to a heat insulation type cable bridge, which comprises a cover plate, two C-shaped side plates of which two openings are correspondingly formed, and a lower bottom plate which is transversely laid at the lower ends of the two C-shaped side plates, wherein two ends of the lower bottom plate are provided with cushion blocks with the same height; an upper bottom plate is laid on the upper end face of the cushion block; and a closed heat insulation space is formed by the lower end face of the upper bottom plate, two corresponding side faces of the two cushion blocks and the upper end face of the lower bottom plate. Due to the heat insulation space, the influence of external temperature on cables inside the cable bridge can be effectively reduced, particularly the thermal conductivity of the air inside the heat insulation space is far lower than the thermal conductivity of metals during a fire, the time of firing the cables during the fire can be effectively delayed, and more time for fighting fire and rescuing the personnel is obtained for firemen.

Description

A kind of heat insulation type cable testing bridge

Technical field

The utility model relates to a kind of cable-laying gear that is used to set up and protect elastic cable paper, relates in particular to a kind of bigger heat insulation type cable testing bridge of carriage span that is applied in.

Background technique

As everyone knows; Cable testing bridge generally is applicable to the places such as cable laying and marine drilling of major works power transformation, erecting cable, large bridge, the subway of large enterprise, thus cable testing bridge use in the public sphere more, and one of cable testing bridge ubiquity on the market is failed to stop in the scene of fire isolated fully cable or is prevented the problem that cable is burnt easily at least now; Therefore; Often in the scene of fire, because of burning cable testing bridge, the reason that cable heated is affected; Hinder fire personnel's rescue progress greatly, also increased personnel's life safety risk.

Summary of the invention

The purpose of the utility model is to overcome the defective of existing technology, provide a kind of simple in structure, and can effectively improve the heat insulation type cable testing bridge of Safety performance.

For realizing above-mentioned purpose; The utility model adopts a kind of heat insulation type cable testing bridge; Comprise the C type side plate of cover plate, two corresponding placements of opening and laterally be layed in the lower shoe of said two C type side plate lower ends; Wherein said lower shoe both sides such as are provided with at high cushion block, are equipped with upper plate on the said cushion block upper-end surface, and said upper plate lower end surface and corresponding two sides of said two cushion blocks and lower shoe upper-end surface form the insulated space of sealing jointly.

Through the above-mentioned improvement to existing technology, owing between lower shoe and upper plate, be provided with insulated space, the air thermal conductivity in this space is more much smaller than the thermal conductivity of metal bottom; Therefore, when breaking out of fire, flare upwards emits; And contact with the lower shoe of cable testing bridge, and the setting of insulated space has reduced the heat-conductive characteristic of cable testing bridge to a great extent; Make that cable can keep having won the more rescue time to the fireman, therefore below the limit of institute's bearing temperature in the quite a long time; The heat insulation type cable testing bridge of the utility model has not only reached simple in structure, and the also higher effect of Safety performance.

Preferably; Said cable testing bridge also comprises two dividing plates; Said dividing plate lower end is welded on the upper-end surface of said upper plate; This dividing plate upper end is welded on the lower end surface of the supporting portion that has on the said C type side plate, and the upper-end surface of said dividing plate and said C type side plate and upper plate forms the side direction insulated space of sealing jointly.

Further improvement through above-mentioned optimal way; Owing to be provided with the side direction insulated space; On-the-spot at wildfire; Prevented that more further the phenomenon that flare advances cable through the side of cable testing bridge with thermal energy transfer from taking place, made the Safety performance of cable testing bridge of the utility model further improve.

Preferably, said cushion block is an insulation board, and this insulation board is preferably the phenolic resin plate.Because the phenolic resin plate has the premium properties of fire-proof and thermal-insulation, so the cushion block of this kind material more is applicable to the cable testing bridge of the utility model.

Description of drawings

Fig. 1 is the utility model embodiment's a plan view.

Embodiment

As shown in Figure 1; The specific embodiment of the utility model is a kind of heat insulation type cable testing bridge; Comprise the C type side plate 1 of cover plate, two corresponding placements of opening and laterally be layed in the lower shoe 2 of said two C type side plate 1 lower ends; Wherein said lower shoe 2 both sides such as are provided with at high cushion block 3, are equipped with upper plate 4 on said cushion block 3 upper-end surfaces, and said upper plate 4 lower end surfaces and said two cushion blocks 3 corresponding two sides and lower shoe 2 upper-end surfaces form the insulated space 5 of sealing jointly.

Also can know in conjunction with Fig. 1; Said cable testing bridge also comprises two dividing plates 6; These dividing plate 6 lower ends are welded on the upper-end surface of said upper plate 4; These dividing plate 6 upper ends are welded on the lower end surface of the supporting portion 10 that said C type side plate 1 upper end has, and said dividing plate 6 and the upper-end surface of said C type side plate 1 and upper plate 4 form the side direction insulated space 7 of sealing jointly.

In the present embodiment, said cushion block 3 is an insulation board, and this insulation board is preferably the phenolic resin plate.

Obviously, the utility model not only is confined to the protection scheme of the foregoing description, so long as based on the spirit of the utility model amplified out be easy to associate or all fall among the protection domain of the utility model with the improvement that doctrine of equivalents is replaced.
