Description

Technical Field

[0001] This utility model relates to the field of rope technology, specifically a three-layer braided conductive alarm feedback rope. Background Technology

[0002] Existing ropes often use metal wires or carbon fibers for conductivity or antistatic purposes, as described in CN207347814U and CN203575300U. However, these ropes do not form a complete circuit and cannot achieve real-time alarm functionality.

[0003] In addition, CN205975174U uses an inductive sensor to detect displacement changes, which has a complex structure and high cost.

[0004] This invention, through a three-layer braided structure and circuit loop design, directly utilizes the resistance change of conductive materials to achieve status monitoring, thus solving the problems of missing loops and indirect monitoring in existing technologies. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides a three-layer braided conductive alarm feedback rope, which overcomes the shortcomings of the prior art and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a three-layer braided conductive alarm feedback rope. The rope has a three-layer braided structure. The outer layer is a wear-resistant metal wire braided layer, with at least one strand of metal wire conductor (such as 304 stainless steel wire) spirally wrapped around the outer layer. The middle layer is an insulating material braided rope (such as UHMWPE fiber), which has a low torsion angle and high strength utilization rate. The core of the rope is a conductive material whose resistance changes when subjected to force. One end of the rope is connected to the outer metal conductor and the core conductive material, and the other end is connected to an external detection instrument (such as a power supply and alarm device), forming a circuit loop.

[0007] Functionality implementation:

[0008] 1. When the outer layer of the rope wears or is stretched under excessive load, causing the metal conductor or the conductive material of the rope core to break, the circuit is cut off, the alarm device is triggered, and the user can receive the alarm information in a timely manner.

[0009] 2. The resistance of the conductive material in the rope core changes when subjected to force. An external detection instrument outputs an electrical signal to provide feedback on information such as the number of times it has been used and the magnitude of the tensile force.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. By connecting the outer metal wires to the conductive material of the rope core to form a closed circuit, this invention can monitor the integrity of the rope in real time. When any conductive path breaks due to severe wear or overload tension, the circuit will immediately disconnect, triggering the alarm device to sound an alarm. This allows users to receive a warning before the rope completely breaks, giving them ample time to take countermeasures, greatly improving safety and preventing potential personal injury or property damage.

[0012] 2. Utilizing the characteristic that the resistance of the conductive material in the rope core changes under stress, this invention can not only monitor extreme conditions such as "breakage," but also monitor changes in resistance value through an external detection circuit, indirectly providing feedback on the magnitude of the tension and the cumulative number of uses of the rope. This provides users with richer status information, achieving a leap from "passive load-bearing" to "active intelligent monitoring," facilitating preventative maintenance and scientific management.

[0013] 3. The sensing function (metal wire and conductive material) is directly integrated into the three-layer braided structure of the rope, eliminating the need for complex and bulky external sensors. This seamless structure does not affect the rope's flexibility, lightweight properties, or other basic performance characteristics, while avoiding the problems of damage and detachment of external sensors, ensuring the long-term stability and reliability of the monitoring function.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-2A three-layer braided conductive alarm feedback rope is disclosed. The rope employs a three-layer braided structure. The outer braided layer 1 is woven from a mixture of metal wire conductor 4 and high-strength fibers such as polyester or nylon. The metal wire conductor 4 is made of 304 stainless steel wire, and a spiral runs through the entire rope. The middle braided rope 2 is woven from UHMWPE fibers, featuring a low torsion angle to improve the rope's strength and durability. The inner conductor 3 serves as the rope core and is made of conductive materials such as copper alloy or carbon fiber composite materials. Under tensile stress, its cross-sectional area decreases, and its resistance increases.

[0019] At one end of the rope, the outer metal wire conductor 4 is connected to the inner wire 3 by welding or crimping; at the other end, the metal wire conductor 4 and the inner wire 3 are respectively connected to external detection instruments, including a power supply 5 and an alarm device 6. The alarm device 6 can be an audible and visual alarm or a wireless transmission module. The entire rope forms a closed circuit.

[0020] When the rope is in use, wear on the outer layer can cause the metal wire conductor 4 or the rope core to break, breaking the circuit and triggering the alarm device 6. Simultaneously, the resistance of the conductive material in the rope core changes under stress; this resistance value is measured by a testing instrument and converted into usage count or tensile force data for intelligent monitoring.

[0021] Finally, it should be noted that in the description of this utility model, the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
