Abstract

The utility model discloses a novel elevator wire rope, aiming at providing a wire rope with surface contact among steel wires on each layer and the steel wires between the adjacent layers, high wearing resistance, high breaking load and long service life. Each strand of steel wire is a compacted strand structure consisting of nineteen heavy wires and six fine wires, wherein the nineteen heavy wires are divided into three layers in such a way that one heavy wire is arranged on a first layer, six heavy wires are arranged on a second layer and twelve heavy wires are arranged on a third layer; and the six fine wires are uniformly distributed in gaps of adjacent heavy wires between the third layer and the second layer. For the elevator wire rope, a surface contact state is adopted among the steel wires on each layer and the steel wires between the adjacent layers, and the surface contact state is also adopted between each strand of steel wire and a rope core, thereby not only the wearing resistance is improved, but also the traction capacity is improved, the elevator operation is more stable and reliable, and the service life of the elevator to is long. The relative sliding between the steel wires is reduced so as to reduce structural stretch of the wire rope.

Description

The novel elevator steel wire rope

Technical field

The utility model relates to a kind of elevator steel wire rope.

Background technology

In order to adapt to heavy duty, high level, high speed or through the needs of the vertical lift elevator of many rope sheaves wiring, elevator requires to have very high anti-wear performance with steel wire rope, to improve service life.At present, elevator with the construction of wire rope schematic diagram as shown in Figure 1, form by a wire rope core 2 and stereotyped writing strand wire 1, per share strand wire is to divide three layers of arrangement by 19 steel wires by the 1-9-9 mode, between the steel wire in every layer, all be the line contact condition between the adjacent layer steel wire, contact area is little, ABRASION RESISTANCE, service life is difficult to satisfy the requirement of service condition.And, be easy to generate relative slip between steel wire and the steel wire, influence the elevator even running.

The utility model content

The utility model is in order to overcome weak point of the prior art, provides between a kind of every layer of steel wire, all is face contact, ABRASION RESISTANCE height, Breaking load height, the elevator steel wire rope of long service life between the adjacent layer steel wire.

The utility model is achieved through the following technical solutions:

A kind of novel elevator steel wire rope, form by a wire rope core and stereotyped writing strand wire, it is characterized in that, per share strand wire is by 19 thick wires and 6 compacting thigh structures that finer wire is formed, wherein, 19 thick wires are that 1 thick wire, the second layer are that 6 thick wires, the 3rd layer are that the mode of 12 thick wires is divided into three layers according to ground floor, and 6 finer wires are evenly distributed in the space of adjacent thick wire between the 3rd layer and the second layer.

Each layer gauge of wire ratio is in the per share strand wire: 6 finer wires: 1 thick wire of ground floor: 6 thick wires of the second layer: 12 thick wires of the 3rd layer=0.4789: 1.2254: 1.0986: 1.0000.

The section of outermost layer thick wire is fan-shaped.

The utlity model has following technique effect:

1. elevator of the present utility model is a compacting thigh structure with per share strand wire in the steel wire rope, the section of outermost layer thick wire is fan-shaped, make between the steel wire in every layer, the steel wire between the adjacent layer all is surface contact state, and, also be surface contact state between per share strand wire and the wire rope core, not only improved anti-wear performance, also improved traction capacity simultaneously, make the elevator operation stable more, reliable, long service life.

2. compare with steel wire rope with the elevator of ordinary construction, Breaking load improves, and the elevator safety coefficient is improved.For example diameter is the 13mm steel wire rope, is 1770 tensile strength grades equally, and the minimum Breaking load of the steel wire rope of ordinary construction is 87.6kN, and the minimum Breaking load of the steel wire rope of new structure is 98.7kN, has improved 12.7% than ordinary construction.When promoting identical load, only need select the steel wire rope of thin specification for use like this, it is little to make equipment occupy the space.

3. because compacting thigh structure itself, during the steel wire rope bearing load, steel wire reduces with relative slip between the steel wire, makes construction of wire rope elongation reduction.The construction of wire rope percentage elongation of ordinary construction is less than 0.20%, and the construction of wire rope percentage elongation of new structure has reduced by 25% less than 0.15% than ordinary construction.

Description of drawings

Fig. 1 is an elevator construction of wire rope schematic diagram in the prior art;

Fig. 2 is an elevator construction of wire rope schematic diagram in the utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in detail.

Elevator with the construction of wire rope schematic diagram as shown in Figure 2 in the utility model, form by a wire rope core 4 and stereotyped writing strand wire 3, per share strand wire is by 19

thick wires

5 and 6 compacting thigh structures that finer wire 6 is formed, wherein, 19 thick wires are that 1 thick wire, the second layer are that 6 thick wires, the 3rd layer are that the mode of 12 thick wires is divided into three layers according to ground floor, promptly the mode according to 1-6-12 is divided into three layers, and 6 finer wires 6 are evenly distributed in the space of adjacent thick wire between the 3rd layer and the second layer.

Each layer gauge of wire ratio is in the per share strand wire: 6 finer wires: 1 thick wire of ground floor: 6 thick wires of the second layer: 12 thick wires of the 3rd layer=0.4789: 1.2254: 1.0986: 1.0000.The section of outermost layer thick wire is fan-shaped.

During production, earlier raw material is carried out pickling and surface treatment, carry out drawing and heat treatment afterwards.Steel wire after the drawing is twisted with the fingers thigh, oiling, compacting, torsade successively, obtains elevator steel wire rope of the present utility model.Through compacting process, make between the steel wire in every layer, the steel wire between the adjacent layer all is surface contact state, the section of outermost layer thick wire is fan-shaped.

Elevator of the present utility model with steel wire rope be mainly adapt to heavy duty, high-rise, at a high speed or through the vertical lift elevator of many rope sheaves wiring, the anti-wear performance and the service life of steel wire rope have been improved, having reduced structural stretch simultaneously, is the desirable substitute that conventional lift commonly used is now used steel wire rope.

Although relate to a kind of novel elevator and carried out special description disclosed with steel wire rope with reference to embodiment, embodiment described above is illustrative and not restrictive, under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
