Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing:

[0013] A household elevator steel wire rope, comprising a metal core (1), an inner strand (2) and an outer strand (3); the outer strand (3) is divided into an inner layer and an outer layer, and is of Valington type; the inner strand The 6 thick steel wires of the layer wrap and twist the central steel wire symmetrically and in line contact; the outer layer includes 6 outer layer steel wires (4) and 6 PPC nylon wires (5).

[0014] Further, the number of the outer layer strands (3) and the inner layer strands (2) is 8.

[0015] Further, the diameter of the PPC nylon wire (5) of the outer layer is smaller than that of the outer steel wire (4), and the outer layer consists of 6 outer layer steel wires (4) embedded in two adjacent inner layers in line contact In the concave part of the steel wire, the 6 PPC nylon wires (5) are respectively wrapped and twisted in the convex par...

Abstract

The invention provides a home elevator steel wire rope which comprises a metal core, an inner-layer strand and an outer-layer strand. The outer-layer strand is divided into an inner layer and an outer layer and is in Walintun type, six thick steel wires of the inner layer symmetrically wraps a central steel wire in a line contact manner, and the outer layer comprises six outer-layer steel wires and six PPC nylon wires. The home elevator steel wire rope has the advantages that the home elevator steel wire is formed by wrapping a central strand with eight single strands (the inner-layer strand) and twisting, and each single strand is formed by symmetrically wrapping the central steel wire with six steel wires in a line contact manner, so that compared with a hemp-core steel wire rope, breaking force of the steel wire rope and uniformity of a rope diameter cleaning rod are improved greatly; a PPC nylon core has high stability, and oil is contained in the PPC nylon core which is high in strength and resistant to pressure, so that lubricating effect of the steel wire rope can be retained for a longer time, wear of the steel wire rope is reduced, fatigue resistance of the steel wire rope is improved, and the home elevator steel wire rope is suitable for home small elevators.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a household elevator wire rope. Background technique [0002] With the continuous progress of society, multi-storey homes are increasing, and small household elevators are becoming popular. The steel wire ropes required are small in size, have better uniformity in diameter, higher breaking force, and better fatigue resistance. This puts forward very high requirements on the steel wire rope, requiring the diameter of the steel wire rope to be thinner and thinner, and the bearing capacity to be higher and higher. At present, steel wire ropes for elevators are mostly 8*19S+NF structural steel wire ropes. This type of steel wire rope has poor windability, poor bearing capacity and fatigue resistance, and short service life. Contents of the invention [0003] The invention provides a domestic elevator wire rope. [0004] In order to solve the above technical problems, the presen...
