Description

A cable end drag protection component Technical Field

[0001] This utility model relates to the field of cable protection technology, specifically to a cable end drag protection component. Background Technology

[0002] Dragging cabling is a common construction method in cable laying. Workers typically use manual or mechanical traction devices to drag the cable from one end point to the other along a pre-planned path. During this process, care must be taken to avoid excessive stretching, twisting, or abrasion of the cable (the pulling force on the cable should not exceed 80% of its allowable tension, and the instantaneous maximum pulling force should not exceed 100% of its allowable tension) to ensure the cable's performance and integrity. To prevent damage to the cable during dragging, a traction netting sleeve with a swivel hook should be used at the dragging end to pull the cable.

[0003] The existing traction net sleeve is made of metal, which may damage the cable during the traction process. At the same time, the metal material is heavy, which is not conducive to easy construction. On the other hand, the shrinkable braided wire harness has many accessories, the manufacturing method is too complicated, which is not convenient for production operations. Moreover, the wire harness is only tightened by heat shrink tubing, which poses a risk of falling off during the traction process. Summary of the Invention

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution, including:

[0008] One end of the expandable network tube is fitted with a drag hook rope, which is used to drag the expandable network tube.

[0009] As a further description of the above technical solution, the expandable mesh tube is formed by weaving threads of different diameters, and the expandable mesh tube shrinks towards the center when subjected to force.

[0010] As a further description of the above technical solution, the expansion range of the expandable network pipe is 1.5-2 times the cable pipe diameter.

[0011] As a further description of the above technical solution, one end of the expandable network tube with the pressure connector is folded together to form an O-ring, and the pressure connector presses and fixes the O-ring.

[0012] As a further description of the above technical solution, the crimping joint includes a crimping portion, which is a hollow circular tube.

[0013] As a further description of the above technical solution, the crimping part is provided with a serrated part, which engages and is fixed with the expandable mesh tube.

[0014] As a further description of the above technical solution, the heat shrink tubing includes a rigid heat shrink layer, and an anti-slip adhesive layer is disposed inside the rigid heat shrink layer.

[0015] As a further description of the above technical solution, the heat shrink tubing has a neck at its end, and the diameter of the neck gradually decreases on the side near the towing hook rope.

[0016] As a further description of the above technical solution, the towing hook rope includes a traction hook, which is fitted inside an O-ring of an expandable mesh tube.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0035] As shown in Figures 1-8, in one embodiment, a cable end drag protection component includes: an expandable network tube 1, a crimp connector 2, a heat shrink tubing 3, and a drag hook rope 4.

[0036] Among them, the crimp connector 2 is sleeved on the outside of one end of the expandable network tube 1 and is used to press and fix the expandable network tube 1. It can be understood that the construction personnel can select the appropriate crimp connector 2 according to the specifications of the expandable network tube 1 and use the crimping tool to apply pressure to press the crimp connector 2 to fix the expandable network tube 1.

[0037] Correspondingly, the heat shrink tubing 3 covers the outside of the crimp connector 2 and is used to cover and protect the crimp connector 2 and the expandable mesh tube 1. It can be understood that the heat shrink tubing 3 is made of a special material and will shrink rapidly and fit tightly to cover the outside of the crimp connector 2 when heated by an external heat source.

[0038] In addition, the drag hook rope 4 is threaded inside one end of the expandable network tube 1 and is used to drag the expandable network tube 1 to ensure that it will not easily fall off during the dragging process.

[0039] Please refer to Figures 1-8. In this embodiment, the expandable mesh tube 1 is woven from plastic monofilaments of different diameters to form an all-in-one mesh structure. The combination of different wire diameters has excellent wear resistance and mechanical properties. When the expandable mesh tube 1 is subjected to the traction force of the drag hook rope 4, its structure will tighten towards the center, thereby tightly wrapping the internal cable 5 and providing reliable physical protection for the cable 5, preventing it from being damaged by external pressure, friction and other factors.

[0040] Specifically, the expandable network tube 1 can be expanded to accommodate 1.5-2 times the diameter of the cable 5, and can adapt to various specifications of cables 5. Whether it is a single bundle of cables 5 or a combination of multiple bundles of cables 5, it can achieve self-locking protection.

[0041] It should be explained in detail that one end of the expandable mesh tube 1 with the pressure connector 2 is folded together to form an O-ring 11, and the pressure connector 2 can be tightly engaged with the expandable mesh tube 1 to press and fix the O-ring 11.

[0042] Please refer to Figures 1-8. In this embodiment, the crimp connector 2 includes a crimping part 21, which is a hollow circular tube. This shape is compatible with the structure of the expandable mesh tube 1 and can apply pressure evenly, thus achieving the functions of fastening and preventing detachment.

[0043] Specifically, the crimping part 21 has a serrated part 22, which tightly engages with the expandable mesh tube 1 during the crimping process, further enhancing the fixing effect and ensuring that the expandable mesh tube 1 and the crimping part 2 can maintain a firm connection under various complex construction environments and usage conditions.

[0044] Furthermore, the heat shrink tubing 3 includes a rigid heat shrink layer 31, and an anti-slip adhesive layer 32 is disposed inside the rigid heat shrink layer 31. It is understood that the rigid heat shrink layer 31 has good heat resistance and mechanical strength, and can resist external impact, wear and corrosion; the internal anti-slip adhesive layer 32 softens during the heat shrinking process and tightly bonds with the surfaces of the crimp joint 2 and the expandable mesh tube 1, forming a strong adhesive force, effectively preventing relative sliding between components.

[0045] Specifically, the heat shrink tubing 3 has a neck 33 at its end. The diameter of the neck 33 gradually decreases on the side closer to the towing hook rope 4, so that the heat shrink tubing 3 can provide heat shrink protection for the crimped fastening position after heating, which can play a secondary reinforcement and anti-slip role while preventing the internal metal cable 5 from scratching the operator's hands.

[0046] Please refer to Figures 1-8. In this embodiment, the towing hook rope 4 includes a traction hook 41 with a spring. The traction hook 41 is fitted inside the O-ring 11 of the expandable mesh tube 1 and has good toughness and fatigue resistance, and can withstand repeated pulling forces.

[0047] Furthermore, the towing hook 41 is connected to a towing rope 42, which is looped around the middle of the towing hook 41. It is understood that the towing rope 42 with the spring-loaded towing hook 41 is looped into the O-ring 11 of the expandable mesh tube 1, and the towing rope 42 tightens the expandable mesh tube 1, causing the cable 5 to move.

[0048] Through the above technical solution, the structure of this application is simple and lightweight, with the functions of high tensile strength, wear resistance and anti-slip, and tight connection. It will not fall off or break under dragging and friction conditions, and can effectively realize the dragging and pulling of cables.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
