Abstract
The invention relates to a compaction-strand steel wire rope for an elevator, consisting of an outer-layer strand and a central strand. The outer-layer strand consists of outer-layer steel wires and inner-layer steel wires which are in staggered arrangement along the circumference direction. The outer-layer strand consists of eight strands, and each strand consists of nine outer-layer steel wires, nine inner-layer steel wires and one central steel wire, wherein each outer-layer steel wire and the central steel wire have the same diameter and are thick steel wires, and the diameter of each inner-layer steel wires is much less than that of each outer-layer steel wires and the central steel wire. In the surface contact steel wire rope, the compression ratio of the outer-layer strand is 11.7 percent, thereby the cross sectional area of the steel wire rope is improved by 10 percent, the breaking force of the whole steel rope is improved by 9.5 percent, the steel wire rope after compaction is compact in structure and uniform in thickness, and the service life of the product is multipled.
Description
Technical field
This patent relates to the steel wire rope of new structure, is suitable at a high speed and special elevator car traction main transmission elevating mechanism.
Background technology
At present, the steel wire rope that is adopted on the lift car traction main transmission elevating mechanism, it all is made up of outer layer strand, internal layer thigh and central strand or outer layer strand and hemp core wire rope core, and outer layer strand generally adopts Xi Lushi or the various line contact structures of watt woods, adopts the round wire twisting of different-diameter to form.
When elevator uses, because steel wire rope and traction sheave and composition lifting transmissions such as directive wheel and car roof wheel drive lift car lifting work.
Because the frequent lifting of elevator is used, and makes that the steel wire of steel wire rope outer layer strand is easy to wear, cause fracture of wire and disconnected thigh, shorten the service life of steel wire rope, and bring harm for elevator safety.
Summary of the invention
The purpose of this invention is to provide a kind of compaction-strand steel wire rope for elevator, the steel wire rope that solution is commonly used causes fracture of wire and disconnected thigh, the problem that shortens the service life of steel wire rope because the steel wire of steel wire rope outer layer strand is easy to wear.
The objective of the invention is to be achieved through the following technical solutions:
The problem to be solved in the present invention provides the compacting steel wire rope that is suitable for high speed or special elevator use.
For addressing the above problem, by the following technical solutions:
A kind of compaction-strand steel wire rope for elevator, form by outer layer strand and central strand, outer layer strand is per share through the compacting aftershaping, cover wire, steel wire of internal layer and core wire become special-shaped well-regulated steel wire by circle through roll-in, die drawing, promptly agree with mutually at each other contact-making surface, form the compacting thigh, described central strand is formed by three strands, and per share central strand forms by hemp core filament twisting.
Described outer layer strand has 8 strands.
Described cover wire and steel wire of internal layer are respectively 9.
Central strand is the hemp core wire rope core, forms by three strands, per sharely is equipped with 5～9 hard sisal hemps according to wirerope diameter is different, and twisted becomes the hemp core wire rope core.
Outer layer strand adopts roll-in or die drawing moulding process to process, and makes steel cord structure become facial-contracted wire rope.
Take such scheme, have the following advantages:
Because it is 11.7% that the facial-contracted wire rope of this patent makes the outer layer strand compression ratio, make the cross-sectional area of rope improve 10%, the whole rope rupture pull force of steel wire rope improves 9.5%, and strand wire structure after compacting is tight, and poker is even, and prolongs product service life at double.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is a kind of structure chart of compaction-strand steel wire rope for elevator.
Among the figure: 1, outer layer strand; 2, central strand; 11, cover wire; 12, steel wire of internal layer; 13, core wire.
The specific embodiment
As shown in Figure 1, a kind of compaction-strand steel wire rope for elevator, form by outer layer strand 1 and central strand 2, outer layer strand 1 is per share through the compacting aftershaping, cover wire 11, steel wire of internal layer 12 and core wire 13 become special-shaped well-regulated steel wire by circle through roll-in, die drawing, promptly agree with mutually at each other contact-making surface, form the compacting thigh, described central strand 2 is formed by three strands, and per share central strand 2 forms by hard sisal hemp twisting.
Described outer layer strand 1 has 8 strands.
Described cover wire 11 and steel wire of internal layer 12 are respectively 9.
