Abstract
The present invention discloses one kind of steel cable for high speed lift. The steel cable consists of outer strands, inner strands and central strands, and the outer strands and the inner strands are arranged alternately in the periphery. It features the three central strands, each of which consists of twisted ethylene-propylene copolymer filaments. The steel cable for high speed lift can retain lubricating oil, has high flexibility and long service life, and is suitable for use in the cage elevating mechanism of high speed lift.
Description
Technical field
The present invention relates to a kind of steel wire rope.Specifically, be steel wire rope not easy to wear, that service life is long, be applicable on the car elevating mechanism of express elevator.
Background technology
At present, used steel wire rope on the elevating mechanism of express elevator car, it all is made up of outer layer strand, internal layer thigh and the central strand that is in the internal layer thigh, and except that outer layer strand and internal layer thigh are to pick up system forms with steel wire, central strand also is to pick up system with steel wire to form.Because central strand is to pick up system with steel wire to form, and is difficult to retain lubricating oil, makes outer layer strand easy to wear, service life is not long.Because central strand is to pick up system with steel wire to form, and steel wire rope hardness is higher, flexibility is relatively poor, also can shorten the service life of steel wire rope again.
Summary of the invention
The problem to be solved in the present invention provides a kind of high-velocity elevator wire rope.This high-velocity elevator wire rope can be kept lubricating oil here, flexibility is good, long service life.
For addressing the above problem, take following technical scheme:
High-velocity elevator wire rope of the present invention contains outer layer strand, internal layer thigh and central strand, is staggered circumferential arrangement between outer layer strand and internal layer thigh.Be characterized in that said central strand forms by three strands, per share central strand forms by the poly-third ethene filament twisting.
Wherein per share central strand can be determined according to the diameter of steel wire rope, can be formed by 15 poly-third ethene filament twistings, also can be formed by 23 poly-third ethene filament twistings, is also formed by 41 poly-third ethene filament twistings.
Take such scheme, have the following advantages:
Because its central strand of high-velocity elevator wire rope of the present invention is to form with the poly-third ethene filament twisting, can retain lubricating oil, makes outer layer strand not easy to wear, thereby has prolonged the service life of steel wire rope.
Because central strand is to form with the poly-third ethene filament twisting, make that the hardness of steel wire rope reduces, softness improves again, so also can prolong the service life of steel wire rope.
Description of drawings
Accompanying drawing is a high-velocity elevator wire rope cross sectional representation of the present invention.
The specific embodiment
As shown in drawings, high-velocity elevator wire rope of the present invention comprises outer layer strand 1, and internal layer thigh 2 is arranged in the outer layer strand 1, and 2 on outer layer strand 1 and internal layer thigh along the circumferential direction are staggered layout.Outer layer strand 1 wherein is made up of stereotyped writing, per sharely form by nine cover wires, nine steel wire of internal layer and a core wire again, and just the diameter of silk is identical and be thick wire cover wire and center, and the steel wire of internal layer diameter is more much smaller than cover wire and center diameter just thread.Internal layer thigh 2 is made up of stereotyped writing, and per share have seven steel wire primary twistings to form, and these seven gauges of wire are identical.Wherein, six roots of sensation guiding principle silk is outer, and a steel wire is a core wire.
Said central strand 3 is formed by three strands, and per share central strand 3 forms by the some poly-third ethene filament twistings.The quantity of the per share central strand 3 used poly-third ethene filaments is decided on the diameter of steel wire rope.If the diameter of steel wire rope is 8mm, the quantity of the then per share central strand 3 used poly-third ethene filaments is 15.If the diameter of steel wire rope is 10mm, the quantity of the then per share central strand 3 used poly-third ethene filaments is 23.If the diameter of steel wire rope is 13mm, the quantity of the then per share central strand 3 used poly-third ethene filaments is 41.
Because central strand 3 adopts the poly-third ethene filament twisting to form, lubricant weight after making twisting wire rope finish on the rope is 0.9～1.2% of steel wire rope weight, adopt steel wires to twist with the fingers to know the traditional steel wire rope that forms to compare with central strand 3, lubricant content is higher, thereby make outer layer strand 1 not easy to wear, prolong service life.Because central strand 3 adopts the poly-third ethene filament twisting to form, make the softness of steel wire rope improve again.And softness one height of steel wire rope also can prolong its service life.
