Abstract
The invention discloses a method for enhancing knot strength of a connector of an interception rope. The method is characterized by comprising the following steps of: getting a first braided rope to serve as the interception rope; getting a second braided rope, and expanding the second braided rope in the radial direction into a hollow tubular shape to obtain a rope sling; then, enabling the end part of the first braided rope to pass through the rope sling; bending the end part with the rope sling; and then, fixing the end part with the first braided rope in the manner of splicing to form the connector with the rope sling. The method for enhancing the knot strength of the connector of the interception rope has the advantages that the connector is sheathed with the rope sling, and moreover, the rope sling is formed by expanding the second braided rope in the radial direction into the hollow tubular shape, i.e. the braided rope is made into a knot protecting jacket to replace a traditional metallic lantern ring, therefore, the knot strength of the connector under tensile load is enhanced, and meanwhile, the problem that the weight is increased is solved, and proper excellent properties, such as the corrosion resistance, the chemical reagent resistance and the solvent resistance of the interception rope, are also kept.
Description
Technical field
The present invention relates to a kind of blocking apparatus, relate in particular to a kind of method that improves interception rope connector knot strength.
Background technology
Along with the development of China's ocean engineering and traffic engineering, high strength cord (interception rope) has been widely used in trawlnet, the interception protection network.And trawlnet, interception net etc. need hand over knot, woollen yarn knitting to form (as shown in Figure 1) by many ropes each other; But because the interception rope is when docking with an other interception rope each other; An end that needs to tackle rope bends to a connector; Its connector too small radius of curvature when stressed can cause that the fiber in the interception rope obviously damages; The knot strength that causes connector causes connector tubercle place disrumpent feelings under tensile load, thereby makes the utilization rate of material decline to a great extent much smaller than self intensity of interception rope.
In order to improve the knot strength of high strength interception rope connector, have plenty of employing at present connector is fixed on the metal collar, thereby the radius of curvature of connector improves its knot strength when stressed to increase.Though the knot strength that this method can make connector is greater than self intensity of interception rope; But the metal collar can make the weight of connector obviously increase; Especially high-intensity interception netting requires knot strength hundred tons of magnitudes; Make a metal collar just weigh tens kilograms like this; For the interception net that a large amount of tubercles are arranged, weight that this method is brought increases and uses inconvenience normally unacceptable, has also weakened the premium properties such as corrosion-resistant, chemical-resistant reagent and solvent resistance of interception rope simultaneously.
Summary of the invention
Technical problem to be solved by this invention provides a kind of knot strength that can improve connector can solve the method that weight increases the raising interception rope connector knot strength of problem again.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of method that improves interception rope connector knot strength comprises following concrete steps:
(1), gets first sennit as the interception rope;
(2), get one section second sennit, and, obtain rope sling with its tubulose that radially struts into hollow;
(3), rope sling is passed in the end of first sennit, have after the end bending of rope sling to insert and with this and compile the fixing connector that has rope sling that forms with first sennit.
The equal diameters of the diameter of described second sennit and described first sennit, the material of described second sennit is identical with the material of described first sennit.
The length of described rope sling equals the girth of described connector.
The material of described first sennit, second sennit is super high molecular weight high-strength polyethylene fiber (UHMWPE) or polyhexamethylene adipamide (PA66) or other high strength fibre.
Compared with prior art; Advantage of the present invention is owing to socket rope sling on connector; And rope sling obtains radially strutted into the tubulose of hollow by one section second sennit after, promptly makes the tubercle protective sleeve with sennit and has replaced traditional metal collar, has improved the knot strength of connector under tensile load; Solve simultaneously the problem that weight increases again, also kept the premium properties such as corrosion-resistant, chemical-resistant reagent and solvent resistance of interception rope itself.

Fig. 2 passes the pilot process sketch map of rope sling for the end of first sennit of the present invention;
The final structure sketch map of the connector that Fig. 3 obtains for the present invention;
Fig. 4 is two structural representations that the interception rope connects of the present invention.
The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in the figure, a kind of method that improves interception rope connector knot strength comprises following concrete steps:
(1), draw materials be UHMWPE first sennit 1 as the interception rope;
(2), drawing materials is one section second sennit of the equal diameters of UHMWPE, diameter and first sennit 1, and with its tubulose that radially struts into hollow, obtains rope sling 2;
(3), rope sling 2 is passed in the end of first sennit 1, have after the end bending of rope sling 2 to insert and with this and compile the fixing connector 3 that has rope sling 2 that forms with first sennit 1.
In the foregoing description; The length of rope sling 2 equals the girth of connector 3; The material of first sennit 1 and second sennit can use polyhexamethylene adipamide (PA66) or other high strength fibre to substitute, and the material of first sennit 1 and second sennit can be different, diameter can be unequal.
Below be the tensile strength test comparison result (it is super high molecular weight high-strength polyethylene fiber (UHMWPE) rope of Dyneema company production of 12 bursts of braidings of 18 millimeters that test experiments adopts diameter, and adopts the mode of butt joint as shown in Figure 4) of interception rope B who connector 3 is with interception rope A and the no rope sling of rope sling 2:
Experimental result shows that the TENSILE STRENGTH of interception rope A is 30 ton forces, and interception rope the disrumpent feelings of A is not to occur in the tubercle place; The TENSILE STRENGTH of interception rope B is 21 ton forces, and the disrumpent feelings tubercle place that occurs in of interception rope B.
