Shield machine is a kind of special engineering machinery of tunnel piercing, modern shield excavation machine light harvesting, mechanical, electrical, liquid, sensing, information technology are in one, have functions such as the excavation cutting soil body, conveying soil quarrel, assembly unit tunnel-liner, the correction of measurement guiding, relate to multi-door subject technologies such as geology, building, machinery, mechanics, hydraulic pressure, electric, control, measurement, and to carry out manufacturing and designing of " cutting the garment according to the figure " formula according to different geology, reliability requirement is high.Shield excavation machine has been widely used in Tunnel Engineering such as subway, railway, highway, municipal administration, water power.
Carry out that tunnel construction has the automaticity height, saves manpower, speed of application is fast, may command ground sedimentation when cavitation, weatherproof, excavation, reduce the influence of above ground structure and do not influence characteristics such as water surface traffic when excavating under water with shield machine, under the situation long at tunnel hole line, that buried depth is bigger, with more economical rationality of shield machine construction.
The disclosed a kind of shield machine cable of Chinese patent CN201170962, comprise master core, core, packed layer and sheath.Along with development of technology and development, shield machine has comprised that information transmits and control system.The cable of single structure can not satisfy the needs of shield machine development.Shield machine is except the needs power cable but also need control system with cable and transmission signals optical cable.Domesticly power cable, control cable and optical cable are made three different cables respectively always, both uneconomical, dangerous again, but also need frequent the replacing, bring very big inconvenience can for user installation and use.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of and on tensile strength properties, satisfy instructions for use, and make power cable and the compound stranding of control cable overlap the tension flexible cable with the composite high pressure rubber with the shield machine that improves degree easy to install and use.
The utility model technical solution problem adopts following technical scheme:
The utility model shield machine with the design feature of composite high pressure rubber cover tension flexible cable is: with optical cable core centering, place the periphery to be twisted into compound cable core jointly with three power cores and a control core; Set gradually from inside to outside at the skin of described compound cable core and to be rubber inner sheath, tension reinforced layer and rubber oversheath.
The utility model shield machine also is with the design feature of composite high pressure rubber cover tension flexible cable:
Described optical cable core is that the outer setting at fiber bundle has the fiber optic protection layer.
Described control core is to be provided with control core rubber coating layer with the stranded back of each root control line skin, and described control line is in control line conductor appearance the control line insulating barrier to be set.
It is the power line core conductor that described power core adopts the 5th kind of zinc-plated soft copper conductor, and what set gradually at the skin of described power line core conductor is that the copper wire of conductive rubber internal shield, the high pressure resistant second third insulation rubber layer, conductive rubber outer shielding layer and double as ground wire adds the fibrage layer.
Compared with the prior art warp, the utility model beneficial effect is embodied in:
1, the utility model has strengthened cable feature with optical cable core centering, control core and the common stranded formation composite cable of moving wire core, is very easy to the installation and the use of cable.
2, the utility model adopts the 8-10 times of stranded lay ratio of stranding, can effectively improve the bending property and the softness of cable, the crooked needs when satisfying work.
3, the utility model can be set to steel wire braid by the tension reinforced layer, increases the tensile property of cable greatly.
