Method of repairing a composite sheath

Abstract

The application relates to a repairing method of a replacement complex sheath. The method comprises the following steps: step 1, sleeving the replacement complex sheath on a cable, and moving the replacement complex sheath to a repairing position; step 2, binding and fixing the end part of the damaged complex sheath by using a cable tie, spreading the replacement complex sheath at the repairing position, covering the exposed cable core by the replacement complex sheath, and binding and fixing the replacement complex sheath by using the cable tie at the position close to the end part of the replacement complex sheath; step 3, evenly dividing the several strands of the replacement complex sheath end part into several strand groups with the same number of strands, and binding and fixing the end part of each strand group; step 4, inserting and weaving each strand group along the length direction of the cable into the undamaged complex sheath, and binding and fixing the end part of each strand group after the insertion and weaving; and step 5, binding and fixing the replacement complex sheath by using the cable tie at every interval along the length direction of the replacement complex sheath. The application can perfectly repair the cable with the damaged and broken complex sheath.

Description

Technical Field

[0001] This invention belongs to the field of cable technology, specifically relating to a method for repairing a re-braided sheath. Background Technology

[0002] Synthetic fiber ropes are widely used in ship mooring and towing. Because the ropes come into contact with ship equipment during use, causing surface wear, a sheath made of synthetic fibers is woven into the outside of the rope to extend its service life. During use, the sheath first rubs against the ship's equipment, causing wear, followed by wear on the load-bearing parts inside the rope. When the outer sheath is damaged, it loses its protective function for the load-bearing parts of the rope.

[0003] Discarding cables with only outer sheath damage while the internal load-bearing components remain intact is economical and wasteful of resources. The traditional method for repairing damaged sheaths involves wrapping the damaged area with thin rope. This method is suitable for cables with short damaged sections, but is extremely inconvenient for longer damaged sections. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a method for repairing re-knitted sheaths.

[0005] The technical solution of the repair method for the re-knitted sheath of the present invention is as follows:

[0006] A method for repairing a re-knitted sheath includes the following steps:

[0007] Step 1: Put the replacement re-braided sheath onto the cable and move the replacement re-braided sheath to the repair area;

[0008] Step 2: Use cable ties to secure the end of the damaged re-knitted sheath. Lay the replacement re-knitted sheath out over the repair area so that it covers the exposed rope core. Use cable ties to secure the replacement re-knitted sheath near the end of the replacement sheath.

[0009] Step 3: Divide the several strands at the replacement braided end into several groups of strands with the same number of strands, and tie the ends of each group of strands tightly.

[0010] Step 4: Insert each rope strand group into the undamaged re-braided sheath along the length of the cable, and tie and fix the ends of each rope strand group after insertion;

[0011] Step 5: Secure the replacement re-knitted sheath at intervals along its length using cable ties.

[0012] As a further improvement to the above technical solution, in step 1, the fixing rope is passed from one end of the replacement braided sheath to the other end. One end of the fixing rope is fixed to the external fixing structure, and the other end is fixed to the eye loop of the cable. The replacement braided sheath is put on the eye loop and moved to the repair site along the length of the cable.

[0013] As a further improvement to the above technical solution, in step 2, first use tape to tie the two ends of the damaged re-knitted sheath tightly, then use thin rope to wrap and tie it tightly to the tape, and use tape to wrap and fix several strands of rope at the end of the damaged re-knitted sheath; use cable ties to bind and tie the replacement re-knitted sheath tightly at a distance of 30 cm from the end of the replacement re-knitted sheath.

[0014] As a further improvement to the above technical solution, in step 3, each rope strand group includes 12 rope strands, and the ends of the 12 rope strands are tied tightly with tape.

[0015] As a further improvement to the above technical solution, in step 4, the rope strands are inserted into the undamaged re-knitted sheath using a cutting tool. The insertion distance of the rope strands is at least 30 cm. The tape at the ends of each inserted rope strand is cut off and several rope strands are trimmed. The rope strands are then wrapped and tied to the undamaged re-knitted sheath using tape. Finally, the re-knitted sheath is wrapped and tied with thin rope at a distance of 5 cm from the end of the inserted rope.

[0016] As a further improvement to the above technical solution, in step 5, thin ropes are used to tie the replacement re-knitted sheath every meter.

[0017] This invention provides a method for repairing re-knitted sheaths, which has the following advantages compared to existing technologies:

[0018] The repair method for re-knitted sheaths of this invention is a novel approach. Compared to existing technologies that simply discard damaged or broken cables, this method perfectly repairs damaged or broken cables with re-knitted sheaths, achieving waste utilization and avoiding waste. The repair method is simple to operate, and the repaired re-knitted sheath maintains its strength, making it suitable for widespread use. Attached Figure Description
