Abstract
A kind of LLSR structures special type hawser, it is made of around a locked coil wire rope twisting six roots of sensation steel wire rope, six roots of sensation steel cord structure is 6 × 19S+6 × 7+1 × 7, it is made of 1 × 7 structure centre stock core, 1 × 7 structure strand of the internal layer six roots of sensation and the outer layer six roots of sensation 1 × 19S structure strand primary twistings, locked coil wire rope seals steel wire by two to six layers of Z-type and is constituted around a central strand twisting, middle core strand structure is 1 × 37WS, the Z-type sealing steel wire is no less than 44, the cable diameter of the present invention is big, close structure, fill factor and rupture pull force are big, and fatigue performance is good.
Description
Technical field
The present invention relates to a kind of LLSR structures special type hawsers, belong to metal product technical field.
Background technology
Existing bridge is mainly the products such as straight Shu Gangsi or steel strand wires with hawser, and the rigidity of cable is big, and elasticity modulus is high,
Poor fatigue properties, fluctuating load load test do not reach requirement, and when use twisting wire rope hawser, cable diameter is small, generally
Diameter in 100mm hereinafter, and there are elasticity modulus low, poor fatigue properties, structural stretch it is big and other issues, bridge can not be met
The requirement of beam construction.
Invention content
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of LLSR structures special type hawser, solve special
Major diameter, elasticity modulus is low, the technical problems such as poor fatigue properties, meets the needs of bridge construction is using hawser.
The LLSR structure special type hawsers of the present invention are made of six roots of sensation steel wire rope around a locked coil wire rope twisting.
The six roots of sensation steel cord structure of the present invention is 6 × 19S+6 × 7+1 × 7, it is by 1 × 7 structure centre stock core, interior
Layer 1 × 7 structure strand of the six roots of sensation and the outer layer six roots of sensation 1 × 19S structure strand primary twistings are constituted, between internal layer strand and outer strands
In line contact condition, laid construction is closely stablized, and cable fill factor and rupture pull force are big, and fatigue performance is good.The present invention's
Six roots of sensation steel wire rope is not traditional layering twisting technology that uses, and is first twisting internal layer rope in tradition, is then twisted in internal layer rope outsourcing
Outer layer strand twisting is constituted, and the steel wire rope of this twisting method production is in point contact state, twists between internal layer strand and outer strands
Close structure processed is unstable, and cable fill factor and rupture pull force are smaller, and fatigue performance is poor.
The locked coil wire rope of the present invention seals steel wire by two to six layers of Z-type and is constituted around a central strand twisting, middle core strand
Structure is 1 × 37WS, is made of 37 steel wire primary twistings, and Z-type sealing steel wire is no less than 44, sealing of the invention
When twisting wire rope, first layer and second layer Z-type sealing steel wire and middle core strand using primary twisting composition, twisting third layer and with
When the Z-type sealing steel wire on upper layer, using one layer of one twisting, i.e. the method for layering twisting, twisting method using the present invention is more general
Logical twisting method effect is preferable, and locked coil wire rope structure is more stable, improves elasticity modulus, and fatigue performance is more preferable.
Beneficial effects of the present invention：
1, cable diameter of the present invention is big, diameter can reach 280 mm or more, and tensile strength is high, improves the carrying energy of steel wire rope
Power.
2, hawser elasticity modulus is big, fatigue performance is good, and fluctuating load load test reaches requirement, solves large diameter
Hawser is in the application technology problem in bridge construction field, and fill the domestic gaps this.
Description of the drawings
Fig. 1 is a kind of LLSR structures special type hawser cross section structure schematic diagram of the present invention.
In figure：In 1- steel wire ropes, 11- central strands core, 12- internal layers strand, 13- outer strands, 2- locked coil wire ropes, 21-
Heart stock, 22-Z types seal steel wire.
Specific implementation mode
A kind of LLSR structures special type hawser of the present invention is described in further detail below in conjunction with attached drawing：
In Fig. 1, it is made of six roots of sensation steel wire rope 1 around 2 twisting of locked coil wire rope.
1 structure of six roots of sensation steel wire rope is 6 × 19S+6 × 7+1 × 7, it is by 1 × 7 structure centre stock core 11, six
1 × 7 construction interior strand 12 of root and 13 primary twisting of the six roots of sensation 1 × 19S structural outside layers strand are constituted, internal layer strand 12 and outer layer strand
It is in line contact condition between rope 13, laid construction is closely stablized, and hawser fill factor and rupture pull force are big.
The locked coil wire rope 2 seals steel wire 22 by two to six layers of Z-type and is constituted around 21 twisting of central strand, core
21 structures of stock are 1 × 37WS, are made of 37 steel wire primary twistings, and the Z-type seals steel wire 22 and is no less than 44.
When described 2 twisting of locked coil wire rope, first layer and second layer Z-type sealing steel wire 22 are with middle core strand 21 using primary
Twisting is constituted, twisting third layer and when sealing steel wire 22 with the Z-type on upper layer, using one layer of one twisting, that is, the method that is layered twisting.
