Description

Technical Field

[0001] This utility model relates to the field of safety rope technology, specifically to a high-strength safety rope. Background Technology

[0002] In scenarios such as high-altitude operations, outdoor rescue, and construction, safety ropes are core equipment for ensuring personnel safety, and their structural stability, load-bearing strength, and reliability directly affect operational safety. Currently available safety rope products are gradually revealing several shortcomings in practical applications:

[0003] Traditional safety rope connection designs have inherent flaws. Most safety ropes are secured using simple buckles, knots, or metal connectors. These methods either loosen or slip after prolonged stress, or the contact points between the metal connectors and the rope lack cushioning. During repeated pulling or vibration, the sharp edges of the metal connectors can easily wear down the rope, reducing its strength and creating safety hazards. Especially when segmenting or adjusting the position of the safety rope, the installation and removal of existing connectors are complex, and it's difficult to ensure consistent tightening force after each connection, further reducing safety.

[0004] The structural strength of existing safety ropes needs improvement. Most existing safety ropes use a single core with an outer sheath, resulting in poor bonding between the core and sheath. Under impact or prolonged tension, the sheath easily slips relative to the core, affecting the overall load-bearing capacity of the rope and potentially causing sheath breakage due to uneven stress. This exposes the core directly to the external environment, accelerating its aging and wear. Furthermore, some safety ropes lack sufficient anti-slip properties. The smooth surface of the outer sheath significantly reduces friction between the worker's hands or equipment and the rope in wet or oily environments, increasing the risk of slippage and operational risks. Utility Model Content

[0005] Technical problems to be solved

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a high-strength safety rope that can effectively solve the problems in the existing technology.

[0007] Technical solution

[0008] This utility model provides a high-strength safety rope, including a safety rope and a locking structure. The locking structure includes two sets of frames rotatably connected by hinges. Each set of frames has two sets of arc-shaped docking grooves on its inner side, and a contact tube is attached to the outer side of each set of docking grooves. One set of frames has two sets of grooves, and the other set of frames has a circular hole on its inner side. The two sets of frames are fixedly connected by locking bolts set in the grooves and the circular hole. The safety rope is placed in the docking groove. The safety rope has a sheath, a reinforcing rope, and a rope core arranged in sequence from the outside to the inside.

[0009] Furthermore, the two sets of docking grooves on both sides can be merged into a circular groove, and the contact tube is a hollow "I" structure, the size of the contact tube being adapted to the size of the docking groove.

[0010] Furthermore, both sets of the grooves are straight groove structures, and the locking bolts are fixed to the inner side of the grooves and locked in place by nuts.

[0011] Furthermore, the reinforcing rope is wound and fixed on the outside of the rope core, and multiple sets are provided. The sheath is sleeved on the outside of the reinforcing rope, and epoxy resin is filled in the gap between the sheath and the reinforcing rope.

[0012] Furthermore, the outer side of the sheath is wrapped with anti-slip grooves.

[0013] Furthermore, each set of contact tubes is made of soft plastic, and multiple sets of protruding structures are longitudinally fixed on its inner wall.

[0014] Beneficial effects

[0015] In this invention, the locking structure of the high-strength safety rope employs a frame with two hinged rotating connections. The arc-shaped docking grooves on the inner side of the frame can be merged into a complete circular groove, allowing for a tight fit with the safety rope body and effectively preventing the rope from swaying or shifting at the connection point. Simultaneously, the soft plastic contact tube adhered to the outside of the docking groove not only precisely fits the docking groove through its "I"-shaped hollow structure, achieving complete wrapping of the rope, but also utilizes the properties of the soft material to reduce rigid friction and compression between the frame and the rope, preventing damage to the rope due to localized stress concentration. Furthermore, the locking bolts and nuts inside the circular holes, secured by the groove (straight groove structure), ensure stable locking force and facilitate installation and disassembly, guaranteeing structural reliability after each connection and significantly reducing the risk of loosening or slippage at the connection point.

[0022] 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. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example: A high-strength safety rope, see attached diagram. Figure 1 - Appendix Figure 4The system includes a safety rope 1 and a locking structure 2. The locking structure 2 includes two sets of frames 21 rotatably connected by hinges 23. Each set of frames 21 has two sets of arc-shaped docking grooves 22 on its inner side, and a contact tube 24 is attached to the outer side of each set of docking grooves 22. One set of frames 21 has two sets of grooves 211, and the other set of frames 21 has a round hole on its inner side. The two sets of frames 21 are fixedly connected by locking bolts 25 set in the grooves 211 and the round hole. The safety rope 1 is placed in the docking groove 22. The safety rope 1 is arranged in the following order from the outside to the inside: sheath 11, reinforcing rope 12, and rope core 13. The locking structure 2 of the high-strength safety rope 1 uses two sets of frames 21 rotatably connected by hinges 23. The arc-shaped docking grooves 22 on the inner side of the frames 21 can be merged into a complete round groove, which can fit tightly with the body of the safety rope 1, effectively preventing the rope from shaking or shifting at the connection point. Meanwhile, the soft plastic contact tube 24 adhered to the outside of the docking groove 22 not only precisely fits the docking groove 22 through its "I"-shaped hollow structure to achieve complete wrapping of the rope, but also utilizes the properties of the soft material to reduce rigid friction and compression between the frame 21 and the rope, preventing damage to the rope due to localized stress concentration. Furthermore, the groove 211 (straight groove structure) is fixed by the locking bolt 25 in the round hole with a nut, ensuring stable locking force and facilitating installation and disassembly. This ensures structural reliability after each connection and significantly reduces the risk of loosening or slippage at the connection point.

[0025] The two sets of docking grooves 22 on both sides can be combined into a circular groove, and the contact tube 24 is a hollow "I" structure. The size of the contact tube 24 is adapted to the size of the docking groove 22. Both sets of grooves 211 are straight groove structures, and the locking bolts 25 are fixed inside the grooves 211 and locked with nuts. The safety rope 1 adopts a three-layer structure design of "sheath 11 + reinforcing rope 12 + rope core 13". The reinforcing rope 12 is wrapped and fixed outside the rope core 13 and multiple sets are set, which can significantly improve the overall load-bearing strength of the rope. When the rope is subjected to external tension or impact, the force can be distributed by multiple sets of reinforcing ropes 12, avoiding excessive local force and breakage. At the same time, the epoxy resin filling the gap between the sheath 11 and the reinforcing rope 12 can tightly bond the sheath 11, the reinforcing rope 12 and the rope core 13 into one, effectively preventing relative slippage between the three, ensuring the uniformity of the rope's force, and avoiding sheath breakage or rope core 13 wear caused by local slippage. In addition, epoxy resin can also act as a sealant, reducing the entry of external moisture, dust and other impurities into the rope body, slowing down the aging rate of reinforcing rope 12 and rope core 13, and extending the service life of safety rope 1.

[0026] The reinforcing rope 12 is wound and fixed on the outside of the rope core 13, and multiple sets are provided. The sheath 11 is sleeved on the outside of the reinforcing rope 12, and epoxy resin is filled in the gap between the sheath 11 and the reinforcing rope 12. Anti-slip grooves are wound on the outside of the sheath 11.

[0027] Each contact tube 24 is made of soft plastic, and its inner wall has multiple sets of raised structures fixed longitudinally. The anti-slip grooves wrapped around the outer side of the sheath 11 can significantly increase the friction of the rope surface, ensuring reliable contact between the operator's hands or equipment and the rope even in harsh environments such as wetness and oil, effectively preventing slippage. This design is particularly suitable for scenarios where personnel hold the rope or equipment works with the rope in high-altitude operations, providing additional protection for operational safety. The contact tube 24 is made of soft plastic, and its inner wall has multiple sets of raised structures fixed longitudinally. On the one hand, the soft material can form a flexible buffer layer between the rope and the frame 21, reducing the wear and compression of the rope caused by rigid contact. On the other hand, the raised structures on the inner side can further enhance the friction between the contact tube 24 and the rope, preventing the rope from sliding in the docking groove 22. At the same time, it can also provide a certain massage-like protection for the rope surface, avoiding local indentations or damage caused by long-term contact, further ensuring the structural integrity and safety of the rope.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
