Description
Technical field
The utility model relates to a kind of cable, particularly a kind of compression-resistant fire cable.
Background technology
Existing cable, generally be layed in subsurface, but accidentally the situation that cable cuts off usually is occurred when being subject to extraneous extruding or construction, the existing construction of cable is often too simple, just simply wrapped up one deck rubber layer, its overall property sheared, shock resistance and fire resistance are poor, and therefore existing cable is not long for useful life, maintenance difficulty, maintenance cost is high.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of shock resistance is good, anti-shearing, fire-resistant, the simple compression-resistant fire cable of structure.
To achieve these goals, the technical solution of the utility model is as follows: a kind of compression-resistant fire cable, comprise three cable cores, described three cable core outer wrapping one deck rubber sleeves, the cylindrical hollow-core construction of described rubber sleeve, be positioned at rubber sleeve and be provided with three cavitys by an elasticity interlayer, described cable core is arranged in each cavity, filling heat insulating wall in cavity, outside three elasticity interlayers, middle forms one and makes a concession chamber, described yielding chamber shape triangular in shape, make a concession inside, chamber in hollow-core construction, described rubber sleeve outer wrap one deck resistance to compression layer, described resistance to compression layer is made up of elastic rubber material, in hollow-core construction in the middle of resistance to compression layer, in the middle of resistance to compression layer, upper and lower side connects a swash plate, swash plate is divided into more than one inflatable chamber by the middle of resistance to compression layer, blanketing gas in described inflatable chamber.
Further, described rubber sleeve outer wrapping one deck is used for fireproof aluminium-foil paper.
Further, form one between described resistance to compression layer and rubber sleeve and to prevent fires separate cavities, in described fire prevention separate cavities, fill full fine sand.
Further, described elasticity interlayer is half-circle-arc shape, and the arc convex surface of three elasticity interlayers is towards middle, and described resistance to compression layer inner transverse lays steel wire.
The beneficial effect of employing technique scheme is: the utility model wraps up three cable cores by elasticity interlayer, play the effect that pressurized is made a concession, and the resistance to compression layer of outermost end can play the effect of antidetonation, interior filling fine sand, play fireproof effect, the utility model structure is simple, and cost of manufacture is low, coefficient of safety is high, long service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is internal structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.
As shown in Figure 1, this uses novel a kind of compression-resistant fire cable, comprise three cable cores 2, described three cable core 2 outer wrapping one deck rubber sleeves 5, the cylindrical hollow-core construction of described rubber sleeve 5, be positioned at rubber sleeve 5 and be provided with three cavitys by an elasticity interlayer 8, described cable core 2 is arranged in each cavity, filling heat insulating wall 7 in cavity, outside three elasticity interlayers 8, middle forms one and makes a concession chamber 6, described yielding chamber 6 shape triangular in shape, make a concession inside, chamber 6 in hollow-core construction, described rubber sleeve 5 outer wrap one deck resistance to compression layer, described resistance to compression layer is made up of elastic rubber material, in hollow-core construction in the middle of resistance to compression layer, in the middle of resistance to compression layer, upper and lower side connects a swash plate 1, swash plate 1 is divided into more than one inflatable chamber 3 by the middle of resistance to compression layer, blanketing gas in described inflatable chamber 3.
Owing to devising inflatable chamber 3, cable itself can play a good resistance to compression shear-stable ability, utilizes inner air to play a bounce, stop force application object continue press down, shock resistance is good, does not affect the normal use of cable.
In the present embodiment, rubber sleeve 5 outer wrapping one deck is used for fireproof aluminium-foil paper, by the effect of this aluminium-foil paper, prevents flame to be burned to cable core inside through fine sand layer, effectively play the effect of isolation flame combustion, and cost is low.
In the present embodiment, form one between resistance to compression layer and rubber sleeve 5 to prevent fires separate cavities, full fine sand 4 is filled in described fire prevention separate cavities, fine sand 4 can play the effect stoping flame combustion, usually fine sand is used to be blocked by burned flame in life, and after fine sand is filled into cable, add stability and the thickness of cable, and fine sand cost is lower.
Further, described elasticity interlayer 8 is in half-circle-arc shape, the arc convex surface of three elasticity interlayers 8 is towards middle, described resistance to compression layer inner transverse lays steel wire (not shown), by the effect of three elasticity interlayers, when cable core is squeezed, make a concession towards centre by elasticity interlayer, prevent cable core to be squeezed and damage, and on the other hand, shock resistance is better.
The beneficial effect of employing technique scheme is: the utility model wraps up three cable cores by elasticity interlayer, play the effect that pressurized is made a concession, and the resistance to compression layer of outermost end can play the effect of antidetonation, interior filling fine sand, play fireproof effect, the utility model structure is simple, and cost of manufacture is low, coefficient of safety is high, long service life.
The beneficial effects of the utility model are: the utility model wraps up three cable cores by elasticity interlayer, play the effect that pressurized is made a concession, and the resistance to compression layer of outermost end can play the effect of antidetonation, interior filling fine sand, play fireproof effect, the utility model structure is simple, and cost of manufacture is low, coefficient of safety is high, long service life.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
