Load-bearing cables are often used in construction operations such as petrochemical engineering, oil and gas field exploration and development, ocean exploration, mining machinery and the like. The load-bearing cable has good mechanical property and electrical property and is expensive. The inner and outer two-layer cable armor of the load-bearing cable is made of high-quality steel wires through special process treatment, and has better toughness and corrosion resistance. The winding directions of the inner and outer layer armored steel wires are opposite, so that the rotation of the load bearing cable under stress and the change of the length are reduced. The cable core wire is wound by a plurality of layers of copper wires and is added with a water plugging agent. The cable core of the load-bearing cable is completely wrapped in the shielding layer. In a complex use environment, load-bearing cables with lengths of thousands of meters or even thousands of meters can cause local performance degradation and faults, and are not usable. The cable with the fault section needs to be cut off and spliced again for use. In the process of splicing the load-bearing cable, the longer armored steel wire needs to be opened and restored, and the armored steel wire can meet the requirement only after being restored to be flat. Otherwise, the indexes such as belt-pressure sealing, length measurement and mechanical performance in the construction process are affected.

The working process of the recovery device of this embodiment is specifically as follows:

when the recovery device is used, the 7J46RX load-bearing cable is laid down for about 35 meters, 24 armor steel wires on the outer layer of the load-bearing cable are divided into three strands (8 steel wires per strand) and opened for about 1.5 meters, the armor and the cable core on the inner layer are fixed at a height of about 1.5 meters, a certain tension of 5-10KN is given to the cable, and the cable of the armor section needing to be opened is straightened and is not less than 1.1 meters away from the ground. The armor restorer 1 is arranged outside the armor of the inner layer of the cable, and one end of the armor restorer 1, which is provided with armor teeth 13, is close to the opening position of the armor of the outer layer. Three strands of outer sheathed steel wire are placed between the three sheathed teeth 13 and the three restorer handles 12 (i.e. through the space between the sheathed teeth 13 and the restorer handles 12). The armor rotator 2 is arranged outside the armor of the inner layer of the load-bearing cable and is about 0.5 m away from the end of the cable. The end of the three strands of outer armor steel wires is placed in the armor positioning block 23 and fixed, the armor rotator 2 is properly pulled by hands, the three strands of outer armor steel wires are in a straight state, the armor restorer 1 and the armor rotator 2 are synchronously rotated according to the opening direction, the armor restorer 1 is close to the outer steel wires and is opened and rotated to move forward, and the armor rotator 2 keeps rotating at a relative fixed position. The outer layer armor steel wire is divided into three strands to be opened together, and when the outer layer armor steel wire is opened for a long time, the installation armor rotator 2 is additionally arranged. The rotating three-strand steel wire is ensured not to collide with the inner armor.

The opened outer armor steel wires are reserved according to one end (defined as A) of the spliced cable, and a section of the cable (defined as B) to be spliced is opened and cut off in the same way as the method. And disassembling the armor restorer 1 and the armor rotator 2, and placing the reserved opened outer armor steel wires for standby. After the cable cores and the inner layers of the two parts of the cables are spliced, the cables are given a certain pulling force of 5-10KN, and the cables of the armor sections needing to be spliced are straightened and are not less than 1.1 m away from the ground. The armored restorer 1 and the corresponding number of armored rotators 2 are installed in an armored opening mode. The armor restorer 1 and the armor rotator 2 synchronously rotate according to requirements, and the three strands of outer armor steel wires are restored to the inner armor. When the general outer layer armor steel wire is not deformed and the thread pitch is not changed, the outer layer armor steel wire can be better recovered on the inner layer armor. If the overlapping and non-uniform condition of the armor recovery steel wires is found, the armor steel wire with the gap generated on one side is overlapped and the other side is the steel wire with abnormal screw pitch. At this time, the end of the wire with abnormal pitch is mounted with the armored pitch changer 3, and the armored pitch changer 3 is rotated as required to restore the pitch of the wire with abnormal pitch to normal.

And continuing to perform armor recovery on the rest strand of steel wire, and opening the section B corresponding to 8 outer layer steel wires as a strand. And the section B outer layer armored steel wire is opened, and the section A outer layer armored steel wire is restored to the groove opened by the section B steel wire. If the strand of steel wire is recovered, one end of the steel wire is superposed with the B section of outer layer armor steel wire, and a gap is generated between one end of the steel wire and the outer layer armor steel wire. The pitch of the cable at the section A is changed by using the armor pitch changer 3 to be the same as that of the outer armor steel wire at the section B, so that the outer armor steel wire is restored to be flat. When the steel wire of the section B is opened for a long time, the armored rotator 2 is installed to fix the end of the steel wire, and the armored restorer 1 and the armored rotator 2 synchronously rotate. The strand of outer armor wires of segment a is returned to the designated position. The steel wire that B section was opened cuts a steel wire and its reservation in the primary importance, and a corresponding steel wire that A section corresponds cuts, and this group of steel wire gap that corresponds is less than 3 mm. And removing the truncated steel wire in the section A, continuing to recover the strand of steel wire for 6 pitches, cutting off one steel wire opened in the section B and keeping the same at the original position, cutting off the corresponding steel wire in the section A, and enabling the gap of the corresponding group of steel wires to be smaller than 3 mm. The remaining steel wires are spliced by adopting the method. And fixing the ends of the steel wires at the gaps of each group of steel wires by using thin stainless steel sheets. By adopting the splicing method of one strand of outer-layer armor steel wire at the A section and one strand of outer-layer armor steel wire at the B section, the remaining two pairs of the outer-layer armor steel wires at the A section and the outer-layer armor steel wires at the B section are spliced. After splicing is completed, the armored pitch changer 3, the armored restorer 1 and the armored rotator 2 are disassembled.
