Abstract

The utility model relates to a filling structure for mobile-type flexible cables and general rubber flexible cables used in coal mines. By extruding the periphery of a tensile element as a reinforcement composition and vulcanizing a rubber material, a rubber strip 1, a rubber strip 2 and a rubber strip 3 are shaped, form a combined filling structure in cables, and are intertwisted together with cable insulated cores on cabling equipment to form cabling cores. A round cable is formed by extruding an outer jacke. The advantages are that: gaps between the insulated cores are filled by the low-cost rubber strips, and thus the cable structure is allowed to be round and compact, and the application amount of expensive sheath rubber is saved; the rubber strips at the centers of the cores can serve mechanical cushion functions, and thus anti-shock and anti-extrusion performances of the cables are improved, product quality is improve, and preferable economic benefits and social benefits are realized.

Description

A kind of colliery is with the interstitital texture that moves type flexible cable and general rubber sleeve flexible cable

Technical field

The utility model relates to a kind of colliery with the interstitital texture that moves type flexible cable and general rubber sleeve flexible cable, belongs to the cable element field, relates in particular to the colliery with the structure of the filling of moving type flexible cable and general rubber sleeve flexible cable with material.

Background technology

At present; In the cable core stranded stranding process of colliery with mobile type flexible cable and general rubber sleeve flexible cable; Become cable core center and peripheral the filling to adopt circular rubber bar interstitital texture or do not use interstitital texture, not rounding of cable core occurs, be expressed in the space between the insulated wire cores at next procedure sheath rubber; The structural unreasonable sheath rubber that makes is wasted greatly; Doing filling with the high sheath rubber of valency of fine quality is the huge consumption to resource, causes cable cost high, and can be because the not rounding of cable core make the inconsistent mass defect that causes off-centre of jacket thickness.

Summary of the invention

The present invention designs in order to address the above problem.

The purpose of the utility model be achieved in that it by rubber bar 1, rubber bar 2, rubber bar 3, tensile elements, supporter, fan-shaped inside radian, fan-shaped outside radian, cable insulation core, become cable core, extrude outer jacket and form.

The utility model solves the technical scheme that its technical problem adopted: when the utility model was applied to cable, rubber bar 1, rubber bar 3 and 4 cable insulation cores twisted together, and rubber bar 1, rubber bar 3 form the combination interstitital texture; Rubber bar 2,

rubber bar

3 and 3 cable insulation cores twist together, and rubber bar 2, rubber bar 3 form the combination interstitital texture; Rubber bar 1, rubber bar 3 and 4 cable insulation cores stranded together stranding core that becomes on stranding equipment extrude outer jacket and form round cable, and rubber bar 1, rubber bar 3 form the combination interstitital texture in cable; Rubber bar 2,

rubber bar

3 and 3 cable insulation cores stranded together stranding core that becomes on stranding equipment extrude outer jacket 10 circular cables, and rubber bar 2, rubber bar 3 form the combination interstitital texture in cable.

The utility model has the advantages that: the space between the insulated wire cores is filled by the low rubber bar of cost; Make construction of cable rounding, compactness, can practice thrift the use amount of the high sheath rubber of price, thereby reduced the cost of cable; The rubber bar that is positioned at the cable core center can also play the mechanical damping effect; Improve the performance of cable shock resistance extruding, improved product quality, have favorable economic benefit and social benefit.
