Abstract

The utility model relates to a kind of wear-resisting elevator cables, it includes conductor, and insulating layer is equipped with outside the conductor, they form conductor element, and more conductor elements form core, and more cores abut one group of cable core of composition side by side, the setting of several groups cable core spacing side by side, is equipped with oversheath outside cable core.The large and medium-sized heavy duty equipment of the utility model effective guarantee runs well safely, can satisfy the jacking system of various equipment.

Description

A kind of wear-resisting elevator cable

Technical field

The utility model relates to a kind of cables, and in particular to a kind of flexibility applied to large and medium-sized heavy duty equipment is mobile It is electrically connected cable.

Background technique

Since the working condition and frequent operation of crane, elevator etc. determine that matched cable must have brilliance Mechanicalness, flexibility, and the anti-characteristic for being frequently bended and winding.In this field, the external import cable of famous brand name Dominate the high-end port electric cable market in China always for a long time.This kind of import cable is by feat of excellent quality characteristic and phase To longer service life, have cable compared with high added value, their product almost monopolizes China's Port Machineries private cable Market.So that domestic cables manufacturing industry wishes to break this technology, price fixing as early as possible, recapturing that market price power becomes must Right trend.

Summary of the invention

Goal of the invention: the purpose of this utility model is to overcome deficiencies in the prior art, provide a kind of effective guarantee Large and medium-sized heavy duty equipment runs well safely, can satisfy the jacking system cable of various equipment.

Technical solution: in order to solve the above-mentioned technical problem, a kind of wear-resisting elevator cable described in the utility model, it is wrapped Conductor is included, insulating layer is equipped with outside the conductor, they form conductor element, and more conductor elements form core, more lines Core abuts one group of cable core of composition side by side, and the setting of several groups cable core spacing side by side is equipped with oversheath outside cable core.

The conductor is soft structure copper conductor.

The insulating layer is ethylene-propylene rubber layer.

The oversheath is polyurethane elastomer layer.

The nominal section of the conductor is in 25mm²And when following, the 6th kind of copper or tinned copper conductor, the conductor are used Nominal section in 35mm²Or more when use the 5th kind of copper or tinned copper conductor.

The core is 12 cores or more, and every 3 or 4 cores are twisted into one group of cable core.

The core grouping is twisted, and multiple groups cable core is simultaneously expelled from.

Tensile elements are equipped in the oversheath.

This product is widely used in the equipment frequently moved, is completed movement of taking down the exhibits with the operating of equipment, is large and medium-sized The powerful guarantee that heavy duty equipment runs well safely can satisfy the requirement of the jacking system cable of various equipment.

The utility model has the advantages that the utility model is compared with prior art, remarkable advantage is: the setting of the utility model overall structure Rationally, there is good flexibility, fatigue resistance, resistance to bend(ing), resistance to corrosion seawater, twisted, multiple groups cable is grouped using core Core and the mode being expelled from greatly improve the flexibility and resistance to bend(ing) of cable, reduce the probability of cable core break, anti-by being arranged Element is drawn, cable tensile property is promoted, is further reduced the probability that cable use process interrupts core.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

The utility model is further described with reference to the accompanying drawings and examples.

As shown in Figure 1, a kind of wear-resisting elevator cable described in the utility model, it includes conductor 1, is soft structure copper Conductor, the nominal section of the conductor 1 is in 25mm²And when following, the 6th kind of copper or tinned copper conductor are used, the conductor 1 Nominal section is in 35mm²Or more when use the 5th kind of copper or tinned copper conductor, outside the conductor 1 be equipped with insulating layer 2, For ethylene-propylene rubber layer, they form conductor element 3, and more conductor elements 3 form core 4, and more cores 4 are side by side against composition one Group cable core 5, the setting of 5 spacing side by side of several groups cable core, the core 4 is 12 cores or more, and every 3 or 4 cores are twisted into one group Cable core 5, the grouping of core 4 is twisted, and multiple groups cable core 5 is simultaneously expelled from, and oversheath 6 is equipped with outside cable core 5, is polyurethane bullet Property body layer, in the oversheath 6 be equipped with tensile elements (not marked in figure).The setting of the utility model overall structure rationally, has There are good flexibility, fatigue resistance, resistance to bend(ing), resistance to corrosion seawater, is grouped and is twisted using core, multiple groups cable core simultaneously squeezes Mode out greatly improves the flexibility and resistance to bend(ing) of cable, reduces the probability of cable core break, by the way that tensile elements are arranged, Cable tensile property is promoted, the probability that cable use process interrupts core is further reduced.

The utility model provides a kind of thinking and method, and there are many method and the approach for implementing the technical solution, with It is only preferred embodiments of the present invention described in upper, it is noted that for those skilled in the art, Without departing from the principle of this utility model, several improvements and modifications can also be made, these improvements and modifications should also regard For the protection scope of the utility model, all undefined components in this embodiment can be implemented in the prior art.
