Description

A kind of mine car trailing cable

Technical field

The utility model is related to a kind of mine car trailing cables.

Background technology

Mine car connects trailing cable, is powered for mine car by trailing cable, trailing cable is moved with mine car, and cable needs to grow Time frequently moves back and forth, it is easy to cause core tired, since every core stress is not quite identical, the core having be caused to exist It is extremely easily broken off in frequent reciprocating movement.

Utility model content

The applicant is directed to disadvantage mentioned above, has carried out Improvement, provides a kind of mine car trailing cable.

Technical solution used by the utility model is as follows：

A kind of mine car trailing cable, including core, band and oversheath, the core twisted synthesizing cable, the twisted section of core Away from being 10~12 times, and insulating layer being wrapped up on the outside of core, core is formed by wire stranding, and the twisting pitch of the conducting wire is 8~ 10 times, the conducting wire is made of thin copper wire, and the band wraps up twisted core and filler, and the oversheath squeezes entirely It is pressed on the outside of band.

The beneficial effects of the utility model are as follows：The mine car trailing cable uses thin copper wire, cross-sectional area of conductor not to become feelings Increase copper wire radical under condition, while increasing the twisting pitch of conducting wire and core, improves the tensile strength of mine car trailing cable, and outer Sheath is extruded in entirely on the outside of band, so that oversheath and stranding cable is bonded completely, can also be increased mine car trailing cable tensile strength, The service life of cable is improved, it is cost-effective, it improves work efficiency, reduces security risk.

Description of the drawings

Fig. 1 is the sectional view of mine car trailing cable provided by the utility model.

In figure：1, core；2, band；3, oversheath；4, insulating layer；5, conducting wire；6, filler.

Specific implementation mode

Below in conjunction with the accompanying drawings, illustrate specific embodiment of the present utility model.

As shown in Figure 1, the mine car trailing cable of the present embodiment, including core 1, band 2 and oversheath 3, core 1 are twisted into The twisting pitch of cable, core 1 is 10~12 times, and insulating layer 4 is wrapped up in 1 outside of core, and core 1 is twisted by conducting wire 5, conducting wire 5 twisting pitch is 8~10 times, and conducting wire 5 is made of thin copper wire, and band 2 wraps up twisted core 1 and filler 6, outside Sheath 3 is extruded in 2 outside of band entirely.

The mine car trailing cable increases copper wire radical in the case of using thin copper wire, cross-sectional area of conductor not to become, and increases simultaneously The twisting pitch of conducting wire 5 and core 1 improves the tensile strength of mine car trailing cable, and when use is not easy to break, and substantially prolonging makes It is cost-effective with the service life, while repair time is shut down after also saving cable fracture, it improves work efficiency, and can avoid The electric leakage hidden danger that cable fracture generates.

Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape The modification of formula.
