Description

Technical Field

[0001] This utility model relates to the technical field of composite rope cores, specifically a high-strength composite rope core. Background Technology

[0002] Composite rope cores are core components of ropes made by combining two or more high-performance materials such as synthetic fibers, metal wires, and polymer matrices through specific processes.

At this time, the composite rope core is prone to breakage due to insufficient strength, causing the workpiece to detach from the composite rope core, which may lead to safety hazards such as workpiece injuring workers. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength composite rope core to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This high-strength composite rope core, through the support mechanism and heat shrink sleeve set on the composite rope core body, when using the composite rope core to lift or raise workpieces in high-risk environments such as bridge, building construction, and ship operations, the heat shrink sleeve contacts the metal wire, thereby supporting and limiting the metal wire.

[0028] Please see Figure 1-6 As shown, this utility model provides a high-strength composite rope core technical solution:

[0029] A high-strength composite rope core includes a composite rope core body 1, on which a support mechanism 2 is installed. The support mechanism 2 includes several metal wires 21 and a support sleeve 22. The several metal wires 21 are evenly distributed circumferentially along the composite rope core body 1. Each metal wire 21 bears the main tensile load. Each metal wire 21 is made of galvanized high-carbon steel, which is low in cost and has high tensile strength. Each metal wire 21 is twisted, and the twisting angle does not exceed 5 degrees. The twisting angle within 5 degrees makes the metal wire 21 almost parallel to the rope core axis, ensuring that the strength utilization rate of the metal wire 21 under tensile load exceeds 95%. However, the high twist of the metal wire 21 can significantly reduce the axial load-bearing efficiency of the metal wire 21. Furthermore, the slight twist makes the stress distribution of the metal wire 21 more uniform during dynamic bending, making the single plane of the metal wire 21 less prone to fatigue fracture after repeated bending. Each metal wire 21 has a support groove 31 on its sidewall. The support groove 31 is spiral-shaped, and the sidewall of each support groove 31 abuts against the sidewall of the composite rope core body 1. The support groove 31 forms a mechanical interlocking structure with the composite rope core body 1. Each metal wire 21 is pre-tensioned, and the pretension of each metal wire 21 is higher than that of the composite rope core body 1. When the pretension of the metal wire 21 is greater than that of the composite rope core body 1, the metal wire 21 will bear more load during use. The metal wire 21 shares the stress of the composite rope core body 1, reduces the tensile deformation of the composite rope core body 1, makes the composite rope core body 1 less prone to fatigue failure, and extends the service life of the composite rope core body 1.

[0030] The support sleeve 22 is made of aramid spiral weave. Through the support sleeve 22, the structural stability and tensile strength of the composite rope core 1 and the metal wire 21 are enhanced. The aramid spiral woven support sleeve 22 has good toughness, high temperature resistance, and corrosion resistance. By covering the outer wall of the composite rope, the aramid spiral weave effectively protects the composite rope core 1, preventing damage caused by external tensile forces or wear during use. Furthermore, the support sleeve 22 improves the fatigue resistance of the composite rope, extends its service life, and enhances the performance of the composite rope core 1 in harsh environments.

[0031] Several heat-shrink sleeves 4 are installed on the outer wall of the support sleeve 22. The heat-shrink sleeves 4 are distributed along the length of the support sleeve 22. A limiting sleeve 5 and a limiting member are installed between two adjacent heat-shrink sleeves 4. The inner wall of the limiting sleeve 5 is provided with a threaded groove, so that the limiting sleeve 5 is not easy to slide relative to the support sleeve 22, thereby improving the stability of the support sleeve 22. Each limiting sleeve 5 has a horizontally opened transmission groove 51 at both ends. The length direction of the transmission groove 51 is consistent with the length direction of the limiting sleeve 5. The side wall of each transmission groove 51 is inserted into the side wall of the heat-shrink sleeve 4. A limiting cavity 6 is horizontally opened on the side wall of each transmission groove 51. The limiting cavity 6 is U-shaped. Specifically, the limiting cavity 6 includes a horizontal groove 61 and two vertical grooves 62. The two vertical grooves 62 are located at both ends of the horizontal groove 61 and are connected to the horizontal groove 61. The limiting component includes a transmission block 7, which is located on the circumferential wall of the heat shrink sleeve 4 and is fixedly connected to the heat shrink sleeve 4. The side wall of the transmission block 7 is slidably connected to the side wall of the vertical groove 62 and the horizontal groove 61 in sequence until the transmission block 7 is transmitted to the set position in the limiting cavity 6, and then the transmission block 7 is limited, thereby limiting the heat shrink sleeve 4 and improving the stability of the heat shrink sleeve 4.

[0032] The worker transfers the heat shrink sleeve 4 and the limiting sleeve 5 to the support sleeve 22 at intervals. The limiting sleeve 5 is limited by the threaded groove on the limiting sleeve 5, which improves the stability of the limiting sleeve 5. At the same time, the worker moves two adjacent heat shrink sleeves 4 on both sides of the limiting sleeve 5 so that the end of the heat shrink sleeve 4 is inserted into the transfer groove 51 on the limiting sleeve 5. Meanwhile, the transfer block 7 on the side wall of the heat shrink sleeve 4 is slidably connected to the side wall of the vertical groove 62. When the side wall of the transfer block 7 is transferred to the point where the vertical groove 62 and the horizontal groove 61 are connected, the worker rotates the heat shrink sleeve 4, thereby driving the transfer block 7 to rotate synchronously until the transfer block 7 is rotated to the point where the horizontal groove 61 is connected to another vertical groove 62. At this time, the worker pulls the heat shrink sleeve 4 again, so that the heat shrink sleeve 4 moves away from the limiting sleeve 5, thereby transferring the transfer block 7 into another vertical groove 62, thus limiting the heat shrink sleeve 4. Furthermore, the spaced heat shrink sleeves 4 and limiting sleeves 5 protect the support sleeve 22 and extend the service life of the support sleeve 22 and the composite rope core. In addition, when the heat shrink sleeve 4 is damaged due to long-term use, the operator can rotate the damaged heat shrink sleeve 4 and separate the transmission block 7 and the heat shrink sleeve 4 from the limiting sleeve 5 through the limiting cavity 6. This makes it convenient for the operator to disassemble and replace the damaged heat shrink sleeve 4, thus preventing the damage to the mushroom heat shrink sleeve 4 from spreading to all heat shrink sleeves 4. This makes it convenient for the operator to disassemble and replace the damaged heat shrink sleeve 4 and saves costs.

[0033] The working principle of this utility model is as follows:

[0034] In this embodiment, a high-strength composite rope core is used by workers who transfer several metal wires 21 onto the composite rope core body 1. The strength of the composite rope core body 1 is increased by twisting and applying pretension. The strength of the metal wires 21 is further enhanced by the support grooves 31 on their sidewalls, thus improving the strength of both the composite rope core body 1 and the metal wires 21. Simultaneously, the strength of the composite rope core body 1 is further enhanced by a support sleeve 22 made of aramid spiral braid. Furthermore, the support sleeve 22, metal wires 21, and composite rope core body 1 are protected by a limiting sleeve 5 and a heat-shrink sleeve 4, extending their service life. Ultimately, this makes the composite rope core body 1 less prone to breakage due to insufficient strength, thereby reducing safety hazards.

[0035] When the heat shrink sleeve 4 is damaged, the worker rotates the heat shrink sleeve 4, which drives the transmission block 7 to rotate synchronously. This allows the transmission block 7 to be transferred from the vertical groove 62 to the horizontal groove 61, until it reaches the connection point between the horizontal groove 61 and another vertical groove 62. The worker then pulls the damaged heat shrink sleeve 4 away from the limiting sleeve 5, causing the heat shrink sleeve 4 to move and move the transmission block 7 into another vertical groove 62, until the transmission block 7 disengages from the other vertical groove 62. This facilitates the worker's disassembly and replacement of the damaged heat shrink sleeve 4. Then, the worker transfers the new heat shrink sleeve 4 and the transmission block 7 to the corresponding limiting sleeve 5, allowing the new heat shrink sleeve 4 to be inserted into the transmission groove 51. After the transmission block 7 on the new heat shrink sleeve 4 is slidably connected to the vertical groove 62, the worker rotates the heat shrink sleeve 4 again, causing the transmission block 7 to be transferred into the horizontal groove 61 and then into another vertical groove 62, thus limiting the new heat shrink sleeve 4 and facilitating the worker's disassembly and replacement.
