Impact-resistant steel wire rope for pile driver

Abstract

The invention relates to an impact-resistant steel wire rope for a pile driver. The impact-resistant steel wire rope is characterized by comprising a steel wire rope core strand, an inner-layer steelwire strand, a filling fiber strand and an outer-layer steel wire strand, wherein the steel wire rope core strand, the inner-layer steel wire strand, the filling fiber strand and the outer-layer steelwire strand are sequentially arranged from inside to outside; the steel wire rope core strand adopts the single high-elasticity shear-resistant fiber strand, and the filling fiber strand is arrangedbetween the inner-layer steel wire strand and the outer-layer steel wire strand, so that a gap between the middle strands of the steel wire rope is greatly reduced, the effective area of the steel wire rope is increased, the compactness of the steel wire rope is improved, the breaking force of the whole steel wire rope is not influenced, the service life is also prolonged, the fatigue resistance is further improved due to the increase of the oil storage capacity, the inter-strand friction buffering impact force can be effectively reduced by filling the fiber strand, the breaking force of the whole steel wire rope is improved, the contact area between each steel wire in the steel wire rope and equipment is increased, and the purpose of prolonging the service life of the steel wire rope is achieved.

Description

technical field [0001] The invention relates to the technical field of steel wire ropes, in particular to an impact-resistant steel wire rope for pile drivers. Background technique [0002] Steel wire rope is a widely used metal product. The steel wire rope is twisted into strands by multi-layer steel wires, and then centered on the rope core, a certain number of strands are twisted into a helical rope. Wire rope has a wide range of applications, and its quality is directly related to industrial production and personal safety. [0003] At present, the wire contact wire ropes used for pile drivers in China, such as 6×19S+IWR, 6×29FI+IWR, 6×36SW+IWR, 6×36SW+IWR, etc., have poor wear resistance and weak extrusion resistance. The characteristics of short service life, the national standard requires that the breaking force coefficient of the wire rope is only 0.356, but the bearing capacity required by the actual use is far greater than the range specified in the standard, resul...

Problems solved by technology

[0003] At present, the wire contact wire ropes used for pile drivers in China, such as 6×19S+IWR, 6×29FI+IWR, 6×36SW+IWR, 6×36SW+IWR, etc., have poor wear resistance and weak extrusion resistance. The characteristics of short service life, the national standard requires that the breaking force coefficient of the wire rope is only 0.356, but the bearing capacity required by the actual use is far greater than the range specified in the standard, resulting in frequent replacement of the wire rope by the user, which increases the cost of the user. If the steel wire rope with the above structure is required to carry a large minimum breaking force, it is necessary to increase the diameter of the steel wire rope to achieve it, which increases the cost of mechanical equipment, which is neither scientific nor economical.
