Description
Technical Field
The invention relates to a manufacturing method of a steel wire rope hand-knitted rigging with a horizontal ring buckle, and belongs to the technical field of steel wire rope rigging production.
Background
The steel wire rope rigging is a rope which is processed by using a steel wire rope as a raw material and is mainly used for hoisting, traction, tensioning and bearing, and is called as a steel wire rope rigging. The steel wire rope rigging can be divided into several types according to different processing modes: inserting and weaving a steel wire rope rigging; pressing wire rope rigging, etc. Wherein, the inserting and weaving steel wire rope rigging is processed into a circular ring shape by inserting one end or two ends.
The end part of the traditional inserting and weaving steel wire rope rigging is directly exposed outside, and the exposed steel wire is removed in a general method by adopting an oxygen cutting mode, so that the steel wire rope is damaged, and the service life is shortened; preferably, the exposed wire is removed by mechanical removal, such as by a shear. In the use process of the steel wire rope rigging manufactured by the method, the exposed steel wires can hurt the hands of a user, and certain potential safety hazards are caused.
With the common use of the hand-knitted steel wire rope rigging, the safety performance is continuously improved, and the requirements on the hand-knitted steel wire rope rigging, such as appearance requirements, internal characteristics and technical conditions, are more and more clear, and particularly, clear technical requirements are provided for installation and use. The prior hand-braided steel wire rope rigging is required to be firm after being inserted and braided, the state is random, but the two ends of the hand-braided steel wire rope are not level, so that great hidden dangers are brought to installation and use safety, particularly, the length of the hand-braided steel wire rope is within 2.5 meters, the thicker the diameter of the rope is, the more obvious the rope is, and the larger the angle is, the larger the installation is, the more force is required to be applied to distortion and deformation. When the cable is used, although the cable is not overloaded, the two ends of the hand-knitted rigging of the steel wire rope are not buckled horizontally, stress points are concentrated, a cable body can be injured, the service life is shortened, and meanwhile, the safe load coefficient is reduced, so that certain potential safety hazards are brought.
Conventionally, a first end of a wire rope is inserted and braided to form a first ring buckle, then a second end of the wire rope is inserted and braided to form a second ring buckle, the second ring buckle is qualified semi-finished product if the inclined angle is 10-70 degrees after the insertion and braiding of the second ring buckle are finished, and then the semi-finished product is shaped to form the wire rope hand-braided rigging with the horizontal ring buckle. However, in the actual operation process, due to the difference in the lengths of the steel wire ropes and the difference in the wire diameters of the steel wire ropes, although the second buckles are spliced in the same manner, the inclination angle of the spliced second buckles is not within the qualified range of 10 ° to 70 °, so that a retest needs to be performed, and the steel wire ropes of the second buckles need to be stranded again. Therefore, the manufacturing method of the steel wire rope hand-knitted rigging with the horizontal buckles is sought, strands can be taken quickly and accurately according to the law, follow-up angle fine adjustment can be carried out, and therefore the semi-finished product is guaranteed to have a reasonable inclination angle, the product after final shaping is enabled to have the horizontal buckles, stress points are reduced, concentration is achieved, the service life is prolonged, the safety load coefficient is guaranteed, and potential safety hazards are eliminated.

B. stranding 2, 3 and 4 strands, and stranding 5, 6 and 1 strand;
C. and (3), 4 and 5 strands are stranded, and 6, 1 and 2 strands are stranded.
The strand dividing method B is a strand advancing method relative to the strand dividing method A, and the strand dividing method C is a strand retreating method relative to the strand dividing method A. Similarly, the C stranding method advances one strand compared with the B stranding method, and the A stranding method retreats one strand compared with the B stranding method. The strand dividing method A is a strand advancing method relative to the strand dividing method C, and the strand dividing method B is a strand retreating method relative to the strand dividing method C.
1.2, stranding and sorting the second ends of the steel wire ropes; the stranding method at the moment is consistent with that of the first end;
1.3, clamping the steel wire rope on the vice frame of the tiger platform in order to enable the second buckle of the first sample to be positioned at a reasonable inclination angle as much as possible;
the vice frame comprises a first vice 101 at the front end and a second vice 102 at the rear end, an operator works behind the second vice 102, the opening direction of a clamping opening of the first vice 101 is longitudinal, the opening direction of a clamping opening of the second vice 102 is transverse, and a hook 103 is arranged above the area between the first vice 101 and the second vice 102.
Firstly, hanging the middle section of a steel wire rope on a lifting hook 103, forming a first buckle at the first end of the steel wire rope, wherein the first end of the steel wire rope is positioned on the ground in front of a first vice 101, the front section of the steel wire rope is positioned in a clamping port of the first vice 101, the clamping port of the first vice 101 is not locked at the moment, then adjusting the angle of the first buckle of the steel wire rope to ensure that the first buckle is vertically arranged, namely, the first buckle is positioned at a certain angle beta when viewed from the operation position of an operator, the initial value is set to be 90 degrees, the main body of the steel wire rope correspondingly rotates at a certain angle along with the rotation of the first buckle, then locking the front section of the steel wire rope by the first vice 101, locking the rear end of the steel wire rope by a second vice 102, and positioning the second end of the steel wire rope to be scattered and spliced in an area right above the second vice 102, namely, positioning the connecting head part in an area right below the second vice 102, the loose strand and braid portions are located in the area directly above the second vise 102. The strands are not shown in detail.

Where α is the angle between the oblique direction of the first eye and the positive x-axis. Subsequent angles of β are similarly defined. According to normal standards, the semi-finished product is qualified, subsequent shaping can be directly carried out, and the production is carried out according to the step of manufacturing the first sample in batch production without the following steps. However, in order to improve the quality of the product, after many tests and detection of the performance of the final product, the angle of alpha is expected to be as close to 40 degrees as possible, and various index performances of the finally obtained product are optimal values. After that we need to fine-tune the tilt angle so that a is close to 40.
Therefore, if the alpha is 30-50 degrees, namely close to 40 degrees, the operation is carried out according to the first sample to produce other steel wire rope hand-knitted riggings, and if the alpha is not in the range close to 40 degrees, the first sample needs to be adjusted, namely the second sample needs to be made.
