Abstract

The utility model relates to the technical field of electric wires and cables, in particular to a special rubber flexible cable for a medium and high speed construction elevator, which comprises a plurality of conductor units, a steel wire rope and a sheath used for wrapping the conductor units and the steel wire rope, wherein the steel wire rope is arranged between the conductor units, the conductor units respectively comprise a wire core, an insulating layer coated on the wire core and a fiber braiding layer coated on the insulating layer, the sheath adopts chloroprene rubber mixture, and the bending extension resistance, cold resistance, wear resistance and anti-aging cracking performance of the cable are greatly improved; the outer insulating diameters of the wire cores are the same, so that the force applied to each wire core is the same when the cable is bent and stretched, and the phenomenon that the wire cores of the conductor are subjected to different forces to cause the core breaking of the cable is avoided; the cable does not have a wrapping layer when the cable core is formed, so that the fiber weaving layer outside the sheath and the insulating cable core and the filling strip extruded by the steel wire rope can be combined more tightly, the strength of the cable can be increased when the cable is bent, and the cable core is prevented from being broken.

Description

Rubber jacketed flexible cable for elevator

Technical Field

The utility model relates to a wire and cable technical field especially relates to a special rubber flexible cable of well, high-speed construction lift.

Background

The construction elevator is a manned cargo-carrying construction machine frequently used in buildings, and is mainly used for the interior and exterior decoration of high-rise buildings, the construction of buildings such as bridges and chimneys, and the like. Once the cable of the construction elevator breaks down, the circuit operation of the elevator is affected, and the elevator cannot operate directly, so that potential safety hazards and shutdown loss are caused. With the progress of technology, construction elevators have been developed into three types, low-speed, medium-speed, and high-speed. The cable for the conventional construction elevator has some problems, the construction elevator generally needs to operate for more than 16 hours a day, the common cable for the construction elevator is distorted, deformed, broken to core breaking after being used on the medium and high-speed construction elevators for several months, the service life of the cable is short, and immeasurable loss and potential safety hazard are caused to construction units.

Disclosure of Invention

In order to overcome the technical defects that the elevator is easy to distort, deform and break skin until the core is broken after being used for a long time in the traditional medium and high speed construction elevator, the invention aims to provide the elevator rubber jacketed flexible cable which is resistant to bending extension, cold resistance, wear resistance and aging cracking.

In order to achieve the purpose, the invention is realized by the following technical scheme:

the utility model provides a hoist is with rubber cover flexible cable, includes a plurality of conductor units, wire rope and is used for the parcel the conductor unit with wire rope's sheath, wire rope locates between the conductor unit, the conductor unit includes the sinle silk respectively, the cladding in insulating layer on the sinle silk and cladding in the fibre weaving layer on the insulating layer.

Furthermore, a filling rubber strip is filled between the steel wire rope and the conductor unit.

Furthermore, the wire core is formed by twisting a plurality of strands of anaerobic soft copper wires.

Further, the sheath is a chloroprene rubber sheath.

Furthermore, the insulating layer is an ethylene propylene rubber insulating layer.

Further, the fiber woven layer is an aramid fiber woven layer.

Further, the outer diameters of the plurality of conductor units are the same.

Further, the steel wire rope is a galvanized steel wire and a stainless steel wire of carbon structural steel.

To sum up, the utility model has the advantages that: 1. the sheath is made of chloroprene rubber mixture, so that the bending extension resistance, cold resistance, wear resistance and aging cracking resistance of the cable are greatly improved, and the service life of the cable is prolonged by times compared with that of the cable for a common construction elevator; 2. the outer insulating diameters of the wire cores are the same, so that the force applied to each wire core is the same when the cable is bent and stretched, and the phenomenon that the wire cores of the conductor are subjected to different forces to cause the core breaking of the cable is avoided; 3. the cable core does not have a wrapping layer during cabling, so that the fiber weaving layer outside the sheath and the insulating wire core and the packing strip extruded by the steel wire rope can be combined more tightly, the strength of the cable can be increased when the cable is bent, and the breakage of the wire core caused by the sharp increase of the tension when the cable is started at a high speed is avoided.

Drawings

Fig. 1 is a schematic cross-sectional structure of the present invention;

the cable comprises a sheath 1, a sheath 2, a conductor unit 3, a fiber braided layer 4, an insulating layer 5, a wire core 6, a steel wire rope 7 and a filling rubber strip.

Detailed Description

The invention will be further described with reference to the accompanying drawings and the following detailed description:

as shown in fig. 1, a rubber jacketed flexible cable for an elevator includes a plurality of conductor units 2, a steel wire rope 6, and a jacket 1 for wrapping the conductor units 2 and the steel wire rope 6, wherein the steel wire rope 6 is disposed between the conductor units 2, and each conductor unit 2 includes a wire core 5, an insulating layer 4 wrapped on the wire core 5, and a fiber braid layer 3 wrapped on the insulating layer 4.

Wherein a filling rubber strip 7 is filled between the steel wire rope 6 and the conductor unit 2.

Wherein, the wire core 5 is formed by twisting a plurality of strands of anaerobic soft copper wires.

Wherein, the sheath 1 is a chloroprene rubber sheath.

Wherein the insulating layer 4 is an ethylene propylene rubber insulating layer.

Wherein, the fiber braided layer 3 is an aramid fiber braided layer.
