1. To vertebra wedge auto-lock wire rope piecing devices, its characterized in that:

  • the device consists of an external aligning vertebral sleeve (1), an A self-locking vertebral inner sleeve (2), an A rope multi-claw locking snap spring (3), a B self-locking vertebral inner sleeve (4), a B rope multi-claw locking snap spring (5) and 5 machine fittings in total;

    the vertebra aligning outer sleeve (1) is a two inner vertebra sleeve connecting piece, the small ends of the two inner vertebra sleeves are oppositely arranged, strand embedding rope grooves of each inner vertebra sleeve and the clamp spring claws of the multi-claw locking clamp spring are equal to the number of steel wire rope strands, the strand embedding rope grooves are uniformly distributed along the bus direction of the vertebra aligning outer sleeve (1) and are staggered with clamp spring claw embedding holes of the multi-claw locking clamp spring according to an equal-angle space of 180 degrees/n, wherein n is the number of the steel wire rope strands, the space between the strand embedding rope grooves is staggered by 180 degrees/n on the left inner vertebra sleeve and the right inner vertebra sleeve, the diameter of the strand embedding rope grooves is slightly larger than the diameter of the strand-dividing single strands of the steel wire rope, but the sectional area is only about 70 percent of the net area of the strand dividing single strands of the steel wire rope, and the inner groove surface of each strand embedding rope groove and the outer surface of the corresponding self-locking vertebra inner sleeve are rough surfaces with large friction coefficients;

    A. b, the end stranded single ropes of the two steel wire ropes are crossed in a staggered mode, the two steel wire ropes are embedded into the strand embedding rope grooves on the opposite side, the steel wire ropes are respectively locked in an extruding mode through self-locking vertebral inner sleeve pipes on the opposite side, and the steel wire ropes are initially locked in a limiting mode through multi-claw locking snap springs;

    the specific joint operation process is as follows;

    two multi-claw locking snap springs and self-locking vertebral inner sleeves with the same specification are taken respectively, grouped according to the forward direction of the big end and respectively inserted and sleeved on the A steel wire rope head (6) and the B steel wire rope head (7), and then a vertebral outer sleeve (1) is taken and inserted and sleeved on the A steel wire rope head (6) or the B steel wire rope head (7);

    pulling out an A steel wire rope head (6) and a B steel wire rope head (7) with proper lengths, splitting the A steel wire rope head and the B steel wire rope head into split ropes a1, a2 and a3... an, B1, B2 and b3... bn respectively along the rope head direction, then approaching the split section points of the A steel wire rope head (6) and the B steel wire rope head (7) respectively, and enabling the split section points to be crossed according to a1, B1, a2, B2, a3 and b3... an and bn;

    gathering the a1, a2 and a3... an which are penetrated with the cross strand rope group corresponding to the end of the vertebra external sleeve (1) at the steel wire rope B, sliding the middle part of the vertebra external sleeve (1) towards the steel wire rope A at the intersection point of the two strand ropes, and enabling the a1, a2 and a3... an to pass through the vertebra external sleeve (1);

    or B1, B2 and b3... bn of the crossed strand rope group corresponding to the end of the vertebra external sleeve (1) is gathered on the steel wire rope A, the middle part of the vertebra external sleeve (1) slides towards the steel wire rope B at the intersection point of the two strand ropes, and the B1, B2 and b3... bn penetrates through the vertebra external sleeve (1);

    clamping and fixing the vertebra aligning outer sleeve (1), straightening each strand of rope a1, a2, a3.. an, B1, B2, b3.. bn while respectively pushing and pressing the A self-locking vertebra inner sleeve (2) and the B self-locking vertebra inner sleeve (4) on the two rope head ends to the middle of the vertebra aligning outer sleeve (1), enabling the rope to enter into the respective embedded strand groove, respectively pressurizing and extruding the A self-locking vertebra inner sleeve (2) and the B self-locking vertebra inner sleeve (4) to a specified position after checking that the positions are accurate, and finally respectively extruding and locking the A rope multi-claw locking snap spring (3) and the B rope multi-strand claw locking snap spring (5), wherein a plurality of snap spring claws of the A rope are dislocated with a plurality of branch rope head ends (8) at equal angles and are free and do not interfere;

    trimming and aligning the joints of the wire rope heads a1, a2, a3... an, B1, B2, b3... bn of all strands of wire rope heads, namely the wire rope head A (6) and the wire rope head B (7).
