Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): the utility model provides an elevator retinue cable, as shown in fig. 1 and fig. 2, include cable inner core 1 and locate the outer core 2 of cable outer of cable inner core 1, cable inner core 1 is equipped with a plurality of cable chambeies 10, the equipment of elevator retinue cable is realized to producer's wiring selection combination according to the difference, inner wall at cable chamber 10 all is equipped with fire-retardant grid piece 11, can realize the effective fire-retardant protection effect to 1 part cable of cable inner core, it has a plurality of pottery limit material to fill in cable inner core 1 simultaneously, because of this material self has the quality light, advantage that fire resistance is good, can effectively promote elevator retinue cable's light and fire resistance.

Outer core 2 of cable locates fire-retardant piece 3 and the outer insulating protective sheath 4 of cable inner core 1 including a pair of fire-retardant piece 3 and the cover of locating 1 both sides of cable inner core, one side that fire-retardant piece 3 and cable inner core 1 were contradicted is equipped with V-arrangement draw-in groove 13, the both ends of cable inner core 1 are equipped with the spacing fixture block 14 with V-arrangement draw-in groove 13 block, it is spacing to the centre gripping of cable inner core 1 that a pair of fire-retardant piece 3 realization is to guarantee that cable inner core 1 follows the stability of elevator lift in-process, can realize the cladding effect to 1 fire prevention protective screen of cable inner. Still wear to be equipped with in fire-retardant piece 3 and strengthen cable 15, can strengthen retinue cable's tensile and stability, reduce retinue cable's the activity of squinting by a wide margin.

Flame-retardant plates 5 are rotatably connected on two sides of the flame-retardant block 3, a separation plate 6 is arranged between the flame-retardant plates 5 on the same side on the opposite flame-retardant block 3, two ends of the separation plate 6 are respectively rotatably connected with the flame-retardant plates 5 on the two sides, the separation plate 6 comprises an isolation sleeve block 7 and an isolation insert block 8 which are mutually inserted, a compression spring 9 is also arranged between the isolation insert block 8 and the inner wall of the isolation sleeve block 7, under the normal state, a producer can keep the isolation insert block 8 inserted into the isolation sleeve block 7 by utilizing the pressure of the insulation protective sleeve 4 in the sleeving state of the insulation protective sleeve 4, and can extrude the compression spring 9, the separation plate 6 and the flame-retardant plates 5 are attached to the surfaces of the flame-retardant block 3 and the cable inner core 1, the further isolation and fire protection of the cable inner core 1 can be realized by utilizing the flame-retardant plates 5 and the separation plate 6, metal fire-retardant plate layers 12 are, the metal fire-resistant sheet layer 12 can not only enhance the shape and the posture stability of the fire-resistant plate 5 and the isolation plate 6, but also enhance the high-temperature resistance and the fire resistance under a large fire condition, is beneficial to increasing the difficulty of the continuous development of the fire condition to the inside of the cable core, and can effectively delay the fire condition and even block the spread of the fire condition to the cable inner core 1; after the condition of a fire takes place, in case the flame ripples and insulating protective sheath 4 part, cause insulating protective sheath 4 to take place to burn out, when the meltdown, because insulating protective sheath 4 disappears to inside annular pressure, can drive the extension of relative length between isolation sleeve 7 and the isolation picture peg under the effect of compression spring 9 elastic potential energy, because 6 both sides of division board are connected with fire-retardant board 5 rotation, thereby drive fire-retardant board 5 for the rotation of fire-retardant piece 3, finally become stable fire-retardant fender in cable inner core 1 appearance, and keep with the separation on cable inner core 1 surface, through the direct contact of the burning things which can get into and cable inner core 1 of restriction delay the stretching of the condition of a fire, improve the fire-resistant reliability of sustainable stable work of cable inner core 1 under emergency. And by utilizing the popping action of the flame retardant plate 5 and the isolation plate 6, the ignited insulating protective sleeve 4 can be stripped, the continuous adhesion of the burning objects on the surface of the cable is reduced, and the further spread of the fire is favorably reduced. In order to ensure the quick peeling action of the insulating protective sleeve 4 after similar ignition, the insulating protective sleeve 4 is provided with a plurality of sections, and the phenomenon that the ignition source is not easily and quickly cut off and possibly occurs in the integrated surface layer protective sleeve is solved.

Because insulating protective sheath 4 locates outermost top layer, in order effectively to reduce and promote the fire-resistant effect of cable under the condition of a fire takes place, be equipped with fire-resistant coating 16 on insulating protective sheath 4's surface, can realize the first protection to elevator retinue cable, inside the quick entering cable of reduction flame etc..

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
