Abstract
The utility model discloses a forged steel wire rope for compensating contact line parts, which mainly comprises a rope core (1), an inner-layer strand (2) and an outer-layer strand (3), wherein the closed round inner-layer strand (2) which consists of a plurality of single strands wraps the outer layer of the rope core (1); and the outer-layer strand (3) consisting of a plurality of single strands wraps the outer layer of the inner-layer strand (2). In the utility model, by forging the steel wire strands or rope, the strands of the steel wire rope undergoes plastic extrusion deformation, so the steel wires contact tightly, the gaps among the steel wires are small, and the inter-steel wire contact stress is reduced; and the structure of the steel wire rope is compact and stable, and compared with common steel wire ropes of the same diameter and strength grade, the steel wire rope has the advantages of larger effective sectional area, higher packing density coefficient, higher bearing capacity and higher transverse deformability, so the breaking force, fatigue durability and stillness of the steel wire rope are improved.
Description
Technical field
The utility model belongs to the steel wire rope technical field, and what relate generally to is a kind of elements of contacting net compensation forge wire rope.Be applicable to contact nets in electrified railways parts compensation steel wire rope.
Background technology
High speed development along with electric railway, requirement to the elements of contacting net compensation arrangement is more and more higher, reasonable cooperation and the single unit system race of considering rope, wheel increase under the little prerequisite, wirerope diameter does not increase substantially, rupture pull force to steel wire rope proposes higher requirement, and existing compensation rope can't satisfy the designing requirement of high-speed railway.
Summary of the invention
The purpose of this utility model is to provide a kind of elements of contacting net compensation forge wire rope.Solve the small dimension that the ordinary student production. art can't satisfy, high-intensity problem reaches that Fracture Force height, ABRASION RESISTANCE are good, endurance, purpose that rotatory is little.
The utility model realizes that the technical scheme that above-mentioned purpose adopts is: a kind of elements of contacting net compensation is made up of wire rope core, internal layer thigh and outer layer strand with forge wire rope, be surrounded by by a plurality of sub-threads being of forming at the skin of described wire rope core and close round internal layer thigh, be surrounded by the outer layer strand of forming by a plurality of sub-threads at the skin of internal layer thigh.
The utility model makes the stock-traders' know-how of steel wire rope be subjected to plasticity crimp by to the forging of steel strand or rope, between each steel wire contact closely, the gap is little, has reduced the compact stress between steel wire; Steel cord structure is closely knit, stable, with same diameter, compare with the ordinary steel rope of intensity level, effective cross sectional area is big, packed density coefficient height, bearing capacity is big, anti-transversely deforming performance is good, to reach the rupture pull force that improves steel wire rope, fatigue durability and non-rotatory.
Description of drawings
Fig. 1 is the structural representation of utility model.
Among the figure: 1, wire rope core, 2, the internal layer thigh, 3, outer layer strand.
The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in Figure 1, forge wire rope is used in a kind of elements of contacting net compensation, and it mainly is made up of wire rope core 1, internal layer thigh 2, outer layer strand 3.Wire rope core 1 can have various ways: can by many steel wires (present embodiment is 1～19) form the thigh; The also core that can form by 4-9 sub-thread (present embodiment is 7 sub-threads); All right fibre core is as wire rope core.Be surrounded by by what a plurality of sub-threads (present embodiment is 4～12) were formed at the skin of wire rope core 1 and be one and close round internal layer thigh 2, each sub-thread of internal layer thigh 2 is made up of 3～19 steel wires.Skin at internal layer thigh 2 is surrounded by the outer layer strand of being made up of a plurality of sub-threads (present embodiment is 6～12) 3, and the steel wire number of forming the sub-thread of each outer layer strand is the 6-29 root.Scribble sealing grease type grease or pitch type grease at the thigh of described steel wire rope and the slotted section between thigh or silk and the silk, reach antirust, lubricated effect.The thigh material therefor of described steel wire rope is: stainless steel or carbon steel or stainless steel add in carbon steel or the carbon steel material and add fibre core/hemp core.
