Background technique

Currently, wirerope used on the elevating mechanism of elevator door-motor, is all by outer layer strand, internal layer stock and in internal layer stock Central strand composition, wherein outer layer strand, internal layer stock and central strand are formed with steel wire twisting, because wirerope is by steel wire system At, and be to avoid being broken easily, not only wirerope outer diameter can be made thicker, but also flexibility is low, then it, cannot be with cunning when passing through pulley The problem of wheel suits completely, is easy to appear derailing, easily cause safety problem.

Utility model content

The purpose of the utility model is to provide a kind of high-flexibility elevator door machine wirerope, with high flexibility and Advantage not easy to break.

The above-mentioned technical purpose of the utility model has the technical scheme that a kind of high-flexibility elevator Door machine wirerope, including steel wire, steel mesh layer, rubber layer and steel wire, steel mesh layer are socketed in outside steel wire, and rubber layer is socketed in steel mesh Layer is outer, and several steel wire intervals are looped around outside rubber layer, and abrasive rubber is socketed with outside steel wire.

By using above-mentioned technical proposal, supporting wire centered on steel wire provides whole structural strength for wirerope, if It sets steel mesh layer and disperses steel wire pulling force using reticular structure, reduce the risk that steel wire is pulled off, spaced apart steel wire is set, in steel When cord is bent, bending degree can be improved on the inside of wirerope by way of filling up interval, compound rubber layer improves wirerope Flexibility, and the tensile capacity of wirerope can also be improved, setting abrasive rubber reduces the abrasion of wirerope and pulley, further Improve the safety of wirerope.

Further, copper sheet is socketed with outside steel wire.

The pulling force of steel wire can not only be shared, moreover it is possible to improve steel using the high ductibility of copper by using above-mentioned technical proposal The bent degree of silk, skin breakage when preventing steel wire from bending.

Further, it is socketed with alignment layers outside rubber layer, offers slot outside alignment layers, is also provided on abrasive rubber inner wall Slot, copper sheet two sides are respectively embedded into the slot.

By using above-mentioned technical proposal, be arranged alignment layers can positioning wire position, avoid steel wire that larger displacement occurs.

Further, passage room is equipped between alignment layers, copper sheet and abrasive rubber, passage room is hole.

By using above-mentioned technical proposal, in wirerope bending, the steel wire of wirerope bending inside is to rubber layer or so Two sides slight shift then makes to increase the contact area with pulley on the inside of wirerope, improves the cooperation intensity with pulley, avoid the occurrence of The problem of derailing.

Further, several thread grooves are offered outside abrasive rubber.

By using above-mentioned technical proposal, the frictional force that thread groove improves wirerope and pulley is set, avoid wirerope with The problem of being had skidded between pulley.

In conclusion the utility model has the following beneficial effects:

1, by the way that the steel wire being spaced apart is arranged outside steel wire, cooperation steel mesh layer, rubber layer and abrasive rubber improve steel wire The flexibility and tension degree of rope, and then improve the degree of safety of wirerope；

2, it avoids generating larger displacement between steel wire by the way that alignment layers are arranged, and then guarantees the presence of passage room；

3, the frictional force between wirerope and pulley is improved by setting thread groove, prevents from skidding.
