CN101519176A - Simple hand splicing method for wire rope sling - Google Patents

Abstract

The invention discloses a simple hand splicing method for a wire rope sling. The method comprises the following steps that: the tail end of the wire rope is evenly separated into two strands; the rope heart belongs to one side arbitrarily; the divided length is determined according to the size of cleat; the two separated rope strands are twisted according to original lay length of the rope; the two rope strands are twisted together to form the cleat according to the required size of the cleat; and then, the each separated rope is spliced according to a new splicing mode; each strand is spliced for 3 times, and six strands of the wire rope are spliced for 18 times totally; and the splicing length of the cleat on each end is required to be between 150 and 300 mm. While meeting the use requirements of hoisting operation, the method greatly reduces the splicing length, and reduces the splicing difficulty, thereby reducing the weight of the sling and labor intensity of a lifting worker, as well as saving production cost.

Description

A kind of simple hand of wire rope sling is inserted the volume method

Technical field

The simple and easy method that the claim-reduction of volume hoist cable is inserted in volume method, the especially craft of ordinary lay six strand steel wire ropes is inserted in the craft that the present invention relates to a kind of wire rope sling.

Background technology

Needs for the weight lifting, to insert by hand and compile the wire rope sling claim-reduction, usual way is to untie terminal each strand of steel rope at present, go back to the steel rope main body according to the big young pathbreaker's steel rope of claim-reduction end, in the terminal oppositely insertion of rope strand steel rope main body, constitute an annular distance at steel cord ends, the slotting volume length of each end claim-reduction is according to steel cable nominal diameter and hoisting weight, and to reach 600mm～1000mm according to practical experience, all interting should firmly be tightened to consistent by the line of centers of slotting steel rope till.To insert the level and smooth and rounding in the position of compiling in order making, should to use proper implements to carry out shaping, make them enter suitable position.But the slotting volume method of this kind is complicated, inserts and compiles the oversize hoist cable heaviness that causes of length, and crane man labour intensity is big, and productive costs is higher.

Summary of the invention

Long in order to solve the slotting volume of the slotting volume method of tradition length, the hoist cable heaviness, crane man labour intensity is big, the more high deficiency of productive costs, what the invention provides a kind of wire rope sling inserts the volume method than simple hand, and this method can significantly reduce slotting volume length, thereby has alleviated hoist cable weight, also reduce simultaneously the labour intensity of crane man, saved productive costs.

The technical solution adopted for the present invention to solve the technical problems is: with the steel rope end according to being divided into two bundles, wire rope core is included into arbitrarily on one side, length separately is according to the decision of claim-reduction size, with two binding yarn thighs after separating, according to the former lay pitch of rope twist with the fingers to, by required claim-reduction size, two binding yarn thigh twisteds are formed claim-reduction, per share rope after will separating is then inserted volume by the new volume mode of inserting, each strand interts and to reach 3 times and get final product, six strand steel wire ropes intert 18 times altogether, and the slotting volume length of each end claim-reduction should reach the requirement of 150mm～300mm according to actual conditions.

The invention has the beneficial effects as follows, when satisfying the lifting operation operating needs, significantly reduced slotting volume length, reduced slotting volume difficulty, thereby just alleviated hoist cable weight, also reduced the labour intensity of crane man simultaneously, saved productive costs.

Description of drawings

Fig. 1 restraints scheme drawings in the invention steel rope end being divided into two;

Fig. 2 twists with the fingers to mutual twisted scheme drawing according to the former lay pitch of rope for two binding yarn thighs among the present invention;

Fig. 3 is rope strand mark scheme drawing among the present invention;

When Fig. 4 compiles for inserting among the present invention, insert volume method scheme drawing.

The specific embodiment

Consult Fig. 1～Fig. 4, a kind of simple hand of wire rope sling is inserted the volume method, changes method and carries out as follows:

A. at first the steel rope end is divided into two bundles, wire rope core is included into arbitrarily on one side, and the steel cable separately length of section determines according to the claim-reduction size;

B. two binding yarn thighs after will separating, according to the former lay pitch of steel cable twist with the fingers to, by required claim-reduction size, twisted mutually;

C. after two binding yarn twisteds being formed claim-reduction, then separately with every thigh in two binding yarns, and will not separate steel cable and mark every thigh from bottom to up successively by A to F, the last every thigh in one side that wire rope core is not included in two binding yarns after will separating simultaneously marks successively by 1 to 3, another side then marks successively by 4 to 6, and other reaches the state of inserting before compiling;

D. insert volume as follows:

1) will be labeled as 1 rope strand and pass A, B successively, between E, the F;

2) will be labeled as 2 rope strand and pass B, C successively, between A, the F;

3) will be labeled as 3 rope strand and pass C, D successively, between A, the B;

4) will be labeled as 4 rope strand and pass D, E successively, between B, the C;

5) will be labeled as 5 rope strand and pass E, F successively, between C, the D;

6) will be labeled as 6 rope strand and pass A, F successively, between D, the E;

Every thigh is taken advantage of a situation and is interted 3 times;

E. compile slotting back and compile the position shaping to inserting, make it level and smooth, rounding with suitable instrument.

In addition, the slotting length of compiling should reach 150mm～300mm in the gained steps d according to putting into practice.
