The cable rack is made with fireproof composite non-toxic material and has the advantages of insulation, anticorrosion, high strength, convenient installation, easy cable replacing, etc. It is suitable for installation in the wall of different shape tunnels.
Description
Technical field
The present invention relates to the high molecular composite material cable rack that a kind of city rail traffic is used.
Background technique
Before the present invention made, the cable bearer that city rail traffic is used used isotropic metallic material manufacturing of homogeneous usually.But the special operation condition that the wet environment of subway tunnel and employing rail reflux in subway engineering makes the easy corrosion of metallic cable support.Along with the increase of the time of putting into effect, this corrosion situation constantly worsens, and becomes the hidden danger that influences metro operation safety at last.Use polymer composite to replace metallic material to make cable bearer, can be effectively and solve the etching problem that Steel Support brings in the tunnel up hill and dale.
When the semiclosed subway tunnel that composite material cable rack is applied in the city rail traffic, polymer composite must meet the fire prevention of subway engineering, low cigarette, nontoxic requirement; And, the drag force that operator trample because the support in the city rail traffic also must bear, produce during the lay cable, the piston wind impact that produces when vehicle move in the tunnel .... or the like the complicated applied force operating mode, so the high molecular composite material cable rack that city rail traffic is used also must have very high mechanical strength.
Because the difference of construction process, circle, horse shoe shaped, rectangle or the like difformity is not only arranged in the subway tunnel, and the construction error during owing to the tube wall sheet assembly unit of reinforced concrete structure causes surface irregularity, thus the polymer composite support how firmly steadily to be installed on the tube wall also be to need the problem that solves.So the high molecular composite material cable rack that city rail traffic is used must possess good moulding process and structure strict and can ingenious installation simultaneously, just can give full play to composite material cable rack and have the superiority more easy for installation than metallic material cable bearer.
Summary of the invention
The purpose of this invention is to provide the high molecular composite material cable rack that a kind of city rail traffic is used, compared with prior art can conveniently install, cable laying, and have corrosion-resistant, fire prevention, intensity height, long service life, manufacturing efficiency advantages of higher.
The high molecular composite material cable rack that city rail traffic of the present invention is used comprises carrier and some transverse arms; The cross section of carrier and transverse arm is I shape or T font structure form, or the combination of these two kinds of structural types (being existing I-shaped structure You You Xia font structure); The junction of transverse arm and carrier is provided with stiffening rib; Transverse arm is made of supporting plane and following transverse arm stiffening rib thereof, bundle for convenience and attached cable, the both sides of transverse arm supporting plane are or/and the transverse arm stiffening rib is provided with several breach or convex, and this breach or convex can be structural types such as rectangular, triangle, semicircle, circular arc, isosceles trapezoid or waveform; At least be provided with upper and lower two mounting holes on the carrier.
The invention described above composite material cable rack, the outer end of its transverse arm preferably are circular arc and upwarp; It is preferably parallel with horizontal plane or 1 °～10 ° upwarp arranged that cable bearer is installed its transverse arm supporting plane of back.
The invention described above composite material cable rack, the last mounting hole on its carrier is preferably circular port, and following mounting hole is preferably the long-round-shape hole, so that regulate the mounting point.For the ease of the cable bearer connection more than two or two is used, can make the end of mounting hole site in carrier, or/and mounting hole site is in the lower end of carrier down, the movable locking structure of circular arc that can implement to lock connection can be made to last mounting hole site by the mounting hole site place in the upper end of carrier; This locking structure is the upper surface of mounting hole (or lower surface) is made concave arc surface (or convex globoidal) and to constitute.Last mounting hole is located at the upper end of carrier and does movable locking structure in the arc-shaped, the supporting frame lower end connection that so also can be convenient to this cable bearer and evacuation platform is integral.When the mounting hole on the carrier is not positioned at the end of carrier, around mounting hole, be provided with stiffening rib.
Cable bearer of the present invention is the special-shaped component that cooperates the polymer composite of enhancing to make through the mould pressing process global formation with short fibre by long fibre or long fibre fabric shop layer.Strength and stiffness difference that can be required according to the cable bearer different parts during manufacturing adopts long fibre shop layer to cooperate with short fibre to strengthen and uses; Long fibre shop layer can be the long continuously yarn of glasscloth or glass fibre; When machine shaping, lay long fibre shop layer and strengthen, make stressed larger part have enough intensity.
Composite material cable rack of the present invention, its carrier can be designed to have corresponding camber or straight shape structure according to the different situations of circular tunnel, horse-shoe tunnel, rectangle metope; Can be designed to suitable angle according to the situation that metope is installed between carrier and the transverse arm, can be right angle, acute angle or obtuse angle, parallel with horizontal plane or 1 °～10 ° upwarp arranged with the transverse arm supporting plane that guarantees to install the back cable bearer.
Composite material cable rack of the present invention can be made and be applicable to city rail traffic line high voltage cable support, low-voltage cable support or the light current of (comprising tunnel, ground, station etc.) (control, communication) cable bearer.
Cable bearer of the present invention is installed on vertical wall or different shape tube wall, is used for cable laying, and its intensity height utilizes breach or convex on its transverse arm easily to bundle and attached cable, and do not need to carry out a large amount of secondary operations; The transverse arm end has circular arc to upwarp structure, can prevent that cable from skidding off transverse arm.Owing to utilize the strong characteristics of polymer composite designability and adopt the manufacturing of mould pressing process global formation, can rationally utilize material, reduce cost and enhance productivity, be fit to produce in batches.
