Abstract
The utility model relates to a bracket fixture for highway tunnel laying of cabling. The bracket fixture comprises a carriage and a clamping block used for clamping a cable on the carriage, wherein the carriage is provided with a semi-circular groove matched with the external diameter of the cable; and the clamping block is in a semi-circular arch bridge shape matched with the semi-circular groove on the carriage. Compared with the prior art, the bracket fixture provided by the utility model has the advantages of high space utilization, wide application range, convenience in installation and the like.
Description
Technical field
The utility model relates to a kind of bridge cable cleat, especially relates to a kind of vcehicular tunnel cabling and uses stent holder.
Background technology
What at present, cable laying was mainly taked is patterns such as direct-burried, comb, cable trough and electric power tunnel.
Directly buried installation is the cable laying mode that adopts the earliest, the remarkable advantage with reduced investment.But directly buried installation suffers the topography and geomorphology restriction more, needs the repetition excavated pavement, and suffers outside destroy easily.At present, in Shanghai Power Network, directly buried installation mainly adopts in relatively low 10kV of importance and following power distribution network.Comb lays and is applicable to that the cable loop number is more, and the location of heavy duties such as motor vehicle is arranged.Comb lays and can cooperate road construction, and accelerating construction progress is invested moderately, can prevent the infringement of outside destroy and termite effectively.The position of area, Shanghai cable line is usually placed on the bicycle lane and pavement of road or its both sides; The comb access hole that has only the active well place in the whole piece path that is laid in exposes on the ground; Very little to traffic impact, be the most frequently used cable laying mode of Shanghai Power Network therefore.But because comb adopts the structure of reinforced concrete protective layer parcel, the radiating condition of cable will cause current-carrying capacity of cable sharply to descend under multiloop situation than the direct-burried time difference.
Cable trough refers to closed no thoroughfare but the openable cable structures of cover plate, and it is arranged with about terrace perhaps has mutually together slightly.Cable trough can be used as many telegrams in reply cable and lays passage, and construction is simple, and cable arrangements and troubleshooting are convenient, but waterproof hidden danger is bigger.Its Open architecture also makes the antitheft of cable and anti-damage ability not strong, in Shanghai is mainly used in transformer station, uses at present.
Lay with respect to direct-burried, comb and cable trough, power cable tunnel mainly contains following two aspect advantages.
At first, power cable tunnel can significantly improve the circuit conveying capacity.Because tunnel internal is an open type, cable directly dispels the heat to air; And direct-burried and comb are embedded in the soil, and cable dispels the heat to soil.The air thermal resistance is significantly less than the soil thermal resistance.Therefore, under the square one, tunnel cabling transmission capacity lays greater than direct-burried and comb.
Secondly, power cable tunnel economizes the land resource.Land resource in the city no longer is confined to land resource on the ground now, and underground land resource is also more and more valuable.Power cable tunnel can be arranged tens telegram in reply cable roads simultaneously, and can avoid overlapping construction for the Future Development headspace in a little relatively space.By contrast, directly buried installation often needs the repetition excavated pavement, receives outside destroy easily.Comb lays and limited by the transmission capacity requirement, often in same comb, can not lay too much return cable.
Along with the fast development in city, the increase of electricity needs, the power transmission network of city part will develop to the underground space, and the application of high-power transformer and electric cable with large cross-section has also proposed very high requirement to underground cable laying environment simultaneously.Number of cables and transmission capacity increase substantially the demand that makes original direct-burried, comb, cable trough mode be difficult to adapt to electric power development, building electric power tunnel is efficient ways.
Summary of the invention
The purpose of the utility model is exactly to provide a kind of utilance height, vcehicular tunnel cabling applied widely, easy for installation to use stent holder for the defective that overcomes above-mentioned prior art existence.
The purpose of the utility model can realize through following technical scheme: a kind of vcehicular tunnel cabling is used stent holder; It is characterized in that; These anchor clamps comprise bracing frame; And cable clip is located at the fixture block on the bracing frame, and described bracing frame is provided with the semi-circular recesses that is complementary with the outside diameter of cable, and described fixture block is the semicircle arch bridge shape that is complementary with bracing frame upper semi-circle connected in star.
Described bracing frame upper semi-circle connected in star is connected through bolt with the fixture block of semicircle arch bridge shape, constitutes the annulus that is complementary with the outside diameter of cable.
Described bracing frame is the square frame shape, and described semi-circular recesses is arranged on the last edge of square frame.
Described semi-circular recesses is provided with 1～5, and described fixture block is provided with the quantity identical with semi-circular recesses.
Be the arch bridge shape in the middle of the described fixture block, the arch bridge both sides are provided with fixed edge, are equipped with fixing hole on each fixed edge, and described bracing frame is provided with and the corresponding connecting hole of fixing hole.
Compared with prior art; The utility model is used same clamps with the cable of many horizontal layings, makes the space availability ratio in the tunnel cross-section high, can be according to the requirement of cable laying in the different use occasions; Be applicable to that occasions such as long highway section, worker's well section, climbing section, cable joint section, gateway section play the effect of supporting cable and protection cable; It is big to be fit to be applied to the clamping cross section, and ampacity is big, and weight is big; Unbending electric cable with large cross-section has directive significance to the use of anchor clamps in the cable work.Between utilance high, applied widely, easy for installation.
