Description

Technical Field

[0001] This utility model relates to the technical field of jute rope core, specifically to a pressure-resistant composite jute rope core. Background Technology

[0002] Jute rope core refers to the core part of a rope made primarily of natural hemp fibers such as jute, flax, and sisal, through weaving, twisting, or composite processes. It is typically used to enhance the rope's flexibility and shock absorption. Jute rope core can be used alone or combined with other materials such as synthetic fibers, metal wires, or resins to improve mechanical properties and environmental adaptability.

[0003] The shortcomings of existing technology: When the aforementioned jute rope core is used in ship mooring lines, it comes into contact with the dock and experiences sliding or rolling friction under the influence of wind and waves. Due to the unevenness of the dock surface, the jute rope core is compressed. Under high pressure, the jute fibers inside the rope core slide laterally along the axis perpendicular to the rope core, thereby damaging the weaving structure of the jute fibers inside the rope core. This makes the jute rope core prone to breakage, thus affecting its service life. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-resistant composite jute rope core to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A pressure-resistant composite jute rope core includes a rope core body, in which reinforcing ribs are coaxially arranged. A support sleeve and a support mechanism are provided on the outer side wall of the rope core body. The inner side wall of the support sleeve is connected to the outer side wall of the rope core body. The support mechanism includes a connecting sleeve, which is sleeved on the support sleeve and rotatably connected to the support sleeve. The outer side wall of the connecting sleeve is used to contact the surface of the dock.

[0006] Preferably, the support mechanism further includes a fixing sleeve and a limiting member. The fixing sleeve is sleeved on the end of the support sleeve and connected to the support sleeve. The fixing sleeve has a fixing groove for the end of the connecting sleeve to be inserted. The limiting member is located in the fixing groove and is connected to the connecting sleeve and used to limit the position of the connecting sleeve.

[0007] Preferably, a transmission groove is horizontally formed on the side wall of the fixed groove, and a rotation groove is formed on the side wall of the transmission groove. The rotation groove is annular and communicates with the transmission groove. A plurality of limiting grooves are formed on the side of the rotation groove near the transmission groove. The plurality of limiting grooves are evenly distributed along the circumference of the fixed sleeve. The limiting member includes a limiting block. One side of the limiting block is connected to the outer side wall of the connecting sleeve, and the other side of the limiting block is used for sliding connection with the side walls of the transmission groove, the rotation groove and the limiting groove.

[0008] Preferably, the support sleeve has multiple connecting grooves on its side wall, and the connecting sleeve contains a number of connecting lines and multiple oil guide lines. The multiple oil guide lines are evenly distributed along the axial direction of the rope core body. One side of each oil guide line is connected to the side wall of the rope core body, and the other side of each connecting line is integrally formed with the oil guide line. The multiple oil guide lines correspond one-to-one with the multiple connecting grooves. The end of each oil guide line away from the connecting line extends into the connecting groove and connects to the side wall of the connecting groove.

[0009] Preferably, each of the connecting lines is spiral-shaped.

[0010] Preferably, the oil guide is made of oleophilic fiber tape.

[0011] Preferably, the connecting wire is a cotton yarn lead wire.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This type of pressure-resistant composite jute rope core, through the setting of reinforcing ribs, support sleeves and support mechanisms on the rope core body, the rigidity of the reinforcing ribs is higher than that of the jute rope core, thus forming an internal support column in the jute rope core, directly resisting external radial pressure. When the rope core body is compressed, the reinforcing ribs bear most of the compressive force, reducing the lateral displacement of the jute fibers in the jute rope core, thus making it less likely to damage the weaving structure of the jute fibers in the jute rope core, making the rope core body less likely to break when compressed. At the same time, through the connecting sleeve slidably connected on the support sleeve, when the jute rope core contacts the dock, the connecting sleeve contacts the dock surface, thus causing the dock surface to wear down the connecting sleeve first. When the connecting sleeve is damaged, the workers can disassemble and replace the damaged connecting sleeve and install a new connecting sleeve, thereby protecting the rope core body and further extending the service life of the rope core body; 2. This type of pressure-resistant composite jute rope core, by setting a fixing sleeve and a limiting component, has the side wall of the connecting sleeve in contact with the dock surface. When the contact part between the connecting sleeve and the dock surface is damaged, the worker rotates the connecting sleeve to a set angle so that the other side of the connecting sleeve is then limited by the limiting component, so that the intact side wall of the connecting sleeve is in contact with the dock surface. When the intact side wall of the connecting sleeve is damaged again, the worker rotates the connecting sleeve again until the connecting sleeve is completely damaged and unusable. The worker then disassembles and replaces the connecting sleeve, thus reusing the connecting sleeve multiple times and saving resources. Attached Figure Description

[0019] Please see Figure 1-5 As shown, this utility model provides a technical solution for a compression-resistant composite jute rope core: A pressure-resistant composite jute rope core includes a rope core body 1. A reinforcing rib 21 is coaxially installed inside the rope core body 1 and is fixedly connected to the rope core body 1. The reinforcing rib 21 is made of PVC-coated stainless steel wire. A support sleeve 22 and a support mechanism 3 are installed on the outer wall of the rope core body 1. The support sleeve 22 is fitted onto the outer wall of the rope core body 1 and fixedly connected to it. The support mechanism 3 includes a fixing sleeve 32, a connecting sleeve 31, and a limiting member. The fixing sleeve 32 is fitted and fixed to the end of the support sleeve 22, and the fixing sleeve 32 is located at the end of the rope core body 1 closest to the dock surface. A threaded groove is provided on the inner wall of the fixing sleeve 32 to increase the friction between the fixing sleeve 32 and the support sleeve 22, making it difficult for the fixing sleeve 32 to move or rotate freely. A fixing groove 41 is provided on the end of the fixing sleeve 32 away from the dock surface, into which the end of the connecting sleeve 31 can be inserted. A transmission groove 42 is horizontally formed on the side wall of the fixed groove 41. The length direction of the transmission groove 42 is consistent with the length direction of the fixed sleeve 32. A rotating groove 43 is horizontally formed on the side wall of the transmission groove 42. The rotating groove 43 is annular and communicates with the transmission groove 42. Several limiting grooves 44 are horizontally formed on the side wall of the rotating groove 43. The several limiting grooves 44 are all connected to the rotating groove 43. The length direction of each limiting groove 44 is consistent with the length direction of the fixed sleeve 32.

[0020] The connecting sleeve 31 is located at the end of the fixed sleeve 32 away from the dock surface, and the inner sidewall of the connecting sleeve 31 is rotatably connected to the outer sidewall of the support sleeve 22. The outer sidewall of the connecting sleeve 31 abuts against the dock surface. The limiting member includes a limiting block 33, which is fixedly connected to the outer sidewall of the connecting sleeve 31. The sidewall of the limiting block 33 is slidably connected to the sidewall of the transmission groove 42, the sidewall of the rotation groove 43, and the sidewall of the limiting groove 44. The limiting block 33 is ultimately transmitted to one of the several limiting grooves 44, thereby limiting the fiber-accessible connecting sleeve 31.

[0021] First, the reinforcing rib 21 is transferred to the rope core body 1. The reinforcing rib 21 enhances the compressive strength of the rope core body 1. The support sleeve 22 is fitted onto the rope core body 1 and the reinforcing rib 21, providing support and protection. When the rope core body 1 and the support sleeve 22 contact the dock surface, the worker first transfers the fixing sleeve 32 to the set position of the support sleeve 22. The friction between the fixing sleeve 32 and the support sleeve 22 limits the fixing sleeve 32. Then, the worker inserts the end of the connecting sleeve 31 into the fixing groove 41 on the fixing sleeve 32, causing the limiting block 33 on the connecting sleeve 31 to slide within the transfer groove 42. When the limiting block 33 connects the transfer groove 42 and the rotation groove 43, the worker rotates the connecting sleeve 31, causing the limiting block 33 to slide into the rotation groove 43. When the worker rotates to the set angle, the limiting block 33 moves into the limiting groove 44, thus connecting the connecting sleeve 31 with the fixed... The position of sleeve 32 is relatively fixed, so that the outer wall of connecting sleeve 31 abuts against the dock surface. When the contact part between connecting sleeve 31 and dock surface is damaged, the staff adjusts the position of connecting sleeve 31. Through the limiting block 33, limiting groove 44, and rotating groove 43, connecting sleeve 31 is transmitted along the direction of fixed sleeve 32 to a set distance and then rotates to a set angle, so that the damaged part of connecting sleeve 31 is separated from dock surface, and the other side of connecting sleeve 31 abuts against dock surface again. Through several limiting grooves 44, the staff rotates connecting sleeve 31 several times, so that connecting sleeve 31 can protect support sleeve 22 and rope core body 1 multiple times, so that support sleeve 22 and rope core body 1 are not easy to break under the pressure of dock surface, extend the service life of rope core body 1, improve the utilization efficiency of connecting sleeve 31, and make it unnecessary for staff to frequently disassemble and replace connecting sleeve 31, thereby saving resources and making it convenient for staff to disassemble and replace connecting sleeve 31.

[0022] The support sleeve 22 has multiple connecting grooves 5, the length direction of each connecting groove 5 is consistent with the radial direction of the support sleeve 22. Multiple oil guide lines 7 are installed inside the support sleeve 22, and multiple connecting lines 6 are evenly distributed around the circumference of the rope core body 1. Each connecting line 6 is spiral-shaped, one side of each connecting line 6 abuts against the side wall of the rope core body 1, and the other side of each connecting line 6 abuts against the inner side wall of the support sleeve 22. Each connecting line 6 is made of cotton yarn, and multiple oil guide lines 7 are installed on each connecting line 6. One end of each oil guide line 7 is integrally formed with the connecting line 6, and the other end of each oil guide line 7 extends to the outside of the support sleeve 22 after passing through the side wall of the connecting groove 5. The side wall of each oil guide line 7 is connected to the side wall of the connecting groove 5. Each oil guide line 7 is made of oleophilic fiber tape. Through multiple oil guide lines 7 and multiple connecting lines 6, oil is transferred to the hemp fibers inside the rope core body 1, so that the oil on the rope core body 1 is evenly distributed, thereby improving the compressive strength of the rope core body 1.

[0023] Since both the support sleeve 22 and the rope core body 1 are located near the dock, in order to prevent the hemp fibers inside the rope core body 1 from softening due to moisture absorption, which would reduce the compressive strength of the rope core, the workers replenished the rope core body 1 with oil. Through the capillary effect, the oil was guided through the oil guide line 7 and the connecting line 6 to the rope core body 1. Through multiple oil guide lines 7 and multiple connecting lines 6, the oil and the rope core body 1 were in full contact. The oil isolated the moisture, causing the hemp fibers to expand and soften after absorbing moisture, thus improving the compressive strength of the rope core body 1. In addition, the oil penetrated into the gaps between the hemp fibers, reducing the internal friction between the hemp fibers, making the pressure distribution more uniform when the rope core body 1 is under pressure, delaying the fiber breakage caused by friction, and further improving the compressive strength of the rope core body 1.

[0024] The working principle of this utility model is as follows: In this embodiment, when the support sleeve 22 on the core body 1 is brought into contact with the dock surface, reinforcing ribs 21 are installed inside the core body 1 to enhance its compressive strength. The worker first installs the fixing sleeve 32 at a predetermined position on the support sleeve 22. Then, the worker adjusts the position of the connecting sleeve 31 so that the side wall of the connecting sleeve 31 inserts into the fixing groove 41 on the fixing sleeve 32. Simultaneously, the limiting block 33 on the connecting sleeve 31 slides into contact with the side wall of the transmission groove 42 until the end of the connecting sleeve 31 abuts against the side wall of the fixing groove 41, and the limiting block 33 is transferred to the connection point between the transmission groove 42 and the rotating groove 43. The worker then rotates the connecting sleeve 31, causing the limiting block 33 to rotate synchronously. When the limiting block 33 rotates to the set angle, the limiting block 33 is transmitted to the connection between the rotating groove 43 and the limiting groove 44. The operator then adjusts the position of the connecting sleeve 31 so that the connecting sleeve 31 moves away from the fixed sleeve 32, thereby transmitting the limiting block 33 into the limiting groove 44, thus limiting the connecting sleeve 31 and the limiting block 33. This makes it difficult for the connecting sleeve 31 to move freely when it comes into contact with the dock surface. The side wall of the connecting sleeve 31 contacts the dock surface, thereby protecting the rope core body 1 and improving the compressive strength of the rope core body 1. When wear occurs at the contact point between the connecting sleeve 31 and the dock surface, the operator rotates the connecting sleeve 31 to a set angle using the limiting block 33, limiting groove 44, and rotating groove 43, so that the intact part on the side wall of the connecting sleeve 31 abuts against the dock surface. When the intact part on the side wall of the connecting sleeve 31 wears again, the operator continues to adjust the position of the connecting sleeve 31, so that the connecting sleeve 31 continues to rotate to a set angle, so that the new intact part on the side wall of the connecting sleeve 31 contacts the dock surface. This cycle is repeated until the connecting sleeve 31 is completely damaged, at which point the operator disassembles and replaces the connecting sleeve 31. This improves the utilization rate of the connecting sleeve 31, saves costs, and makes the rope core body 1 less prone to breakage, thereby extending the service life of the rope core body 1.

[0025] In addition, oil is transmitted to the rope core body 1 through multiple oil guide lines 7 and multiple connecting lines 6. On the one hand, the oil isolates moisture, so the hemp fibers of the rope core body 1 are less likely to absorb moisture and swell and soften, thereby improving the compressive strength of the rope core body 1. On the other hand, the oil penetrates into the gaps between the hemp fibers, reducing the internal friction between the hemp fibers, so that when the rope core body 1 is subjected to pressure, the pressure distribution is more uniform, making the fibers less likely to break due to friction, further improving the compressive strength of the rope core body 1.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
