Abstract
A kind of QQSR structures special type hawser, it is made of seven steel wire ropes around steel cable core twisting, seven steel wire ropes are made of 1 × 7 structure centre stock core, six roots of sensation construction interior strand and seven 1 × 19S structural outside layers strand primary twistings, Steel cord is made of 1 × 7 structure centre stock, 1 × 7 construction interior stock of the six roots of sensation and seven 1 × 19S structural outside layers stock primary twistings, it is in line contact condition between hawser stock and stock, laid construction is closely stablized, and hawser fill factor and rupture pull force are big.Cable diameter of the present invention is big, and flexibility is good, greatly improves hawser bearing capacity, meets the needs of key project construction is to extraordinary hawser.
Description
Technical field
The present invention relates to a kind of QQSR structures special type hawsers, belong to metal product technical field.
Background technology
Existing thick diameter cables diameter is generally more than 60mm, and maximum can reach 190mm, rupture pull force and bearing capacity
It is small, and cable structure is complicated, production difficulty is big, and flexibility is poor, and structural stretch is big, it is impossible to meet key project construction demand, and
Using boundling steel wire, the rigidity of hawser is big, and flexibility is poor, can not meet particular surroundings requirement.
Invention content
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of QQSR structures special type hawser, solve special
Kind cable diameter is small, and the technical problems such as flexibility and poor fatigue properties meet the needs of key project construction is to extraordinary hawser.
A kind of QQSR structures special type hawser of the present invention is made of seven steel wire ropes around steel cable core twisting.
Seven steel cord structures of the present invention are 7 × 19S+6 × 7+1 × 7, it is by 1 × 7 structure centre stock
Core, six roots of sensation construction interior strand and seven 1 × 19S structural outside layers strands primary twistings are formed, internal layer strand and outer strands it
Between in line contact condition, laid construction is closely stablized, and hawser fill factor and rupture pull force are big.
Steel cord structure of the present invention is 7 × 19S+6 × 7+1 × 7, it is by 1 × 7 structure centre stock, six
1 × 7 construction interior stock of root and seven 1 × 19S structural outside layers stocks primary twistings are formed, and are contacted between internal layer stock and outer layer strand in line
State, laid construction are closely stablized, and hawser fill factor and rupture pull force are big.
Beneficial effects of the present invention：
1st, cable diameter is big, and flexibility is good, good compared with same diameter cables or steel tendon flexibility.
2nd, cable diameter is big, diameter can reach 280 more than mm, improves the bearing capacity of steel wire rope, solves current state
The technical issues of inside there is no 280 more than mm extraordinary hawser productions fills the domestic gaps, can meet ocean engineering salvage, anchoring,
The demand of bridge cable and Large-scale Hoisting rigging high bearing capacity.
Description of the drawings
Fig. 1 is a kind of QQSR structures special type hawser cross section structure schematic diagram of the present invention.
In figure：1- steel wire ropes, 11- central strands core, 12- internal layers strand, 13- outer strands, 2- Steel cords, 21- centers
Stock, 22- internal layers stock, 23- outer layer strands.
Specific embodiment
A kind of QQSR structures special type hawser of the present invention is described in further detail below in conjunction with attached drawing：
In Fig. 1, QQSR structure special types hawser of the invention it be made of seven steel wire ropes 1 around 2 twisting of steel cable core.
Seven 1 structures of steel wire rope are 7 × 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 seven 1 × 19S structural outside layers strand, 13 primary twistings are formed, internal layer strand 12 and outer layer strand
Closely stablize in line contact condition, laid construction between rope 13, hawser fill factor and rupture pull force are big.
2 structure of Steel cord is 7 × 19S+6 × 7+1 × 7, it is by 1 × 7 structure centre stock 21, a six roots of sensation 1
× 7 construction interior stocks 22 and seven 1 × 19S structural outside layers stock, 23 primary twistings are formed, and are between internal layer stock 12 and outer layer strand 13
Line contact condition, laid construction are closely stablized, and hawser fill factor and rupture pull force are big.
