[0021] In order to enable those skilled in the art to better understand the solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Refer to Figure 3 As shown, the present utility model includes an outer jacket for detachably mounting on the cylindrical belt body 1, which includes an outer jacket body 21 made of a flexible material.

[0023] Specifically, the outer jacket body 21 is composed of fiber filaments arranged in a stepless parallel manner and is made by twisting single-strand fiber filaments. A flame-retardant and anti-corrosion protection sleeve 22 and a wear-resistant and tensile protection sleeve 23 are sequentially and fixedly sleeved on the outer surface of the outer jacket body 21. The flame-retardant and anti-corrosion protection sleeve 22 is adhesively sleeved on the outside of the outer jacket body, and the wear-resistant and tensile protection sleeve 23 is adhesively sleeved on the outside of the flame-retardant and anti-corrosion protection sleeve 22.

[0024] The flame-retardant and anti-corrosion sheath 22 includes an anti-corrosion layer 221 and a flame-retardant layer 222 arranged in sequence from inside to outside. The anti-corrosion layer 221 and the flame-retardant layer 222 are adhesively connected, and the anti-corrosion layer 221 is a polyurethane coating; the flame-retardant layer 222 is a fiberglass flame-retardant mesh layer. The polyurethane coating as the anti-corrosion layer 221 can effectively resist the erosion of various chemical substances, prevent the outer sheath 2 from being damaged due to external corrosion, and is beneficial to extending the service life of the outer sheath 2. The fiberglass flame-retardant mesh layer as the flame-retardant layer 222 provides excellent flame-retardant performance, can protect the outer sheath 2 from the threat of fire spread in case of emergencies such as fires, improves the overall safety; at the same time, it can improve the overall structural stability of the outer sheath 2.

[0025] The wear-resistant and tensile-resistant sheath 23 is formed by the floating interweaving of warp threads 231 and weft threads 232. The warp threads 231 are polyester fiber filaments, and the weft threads 232 are nylon fiber filaments, and the warp threads 231 and the weft threads 232 are interwoven into a herringbone pattern.

[0026] Specifically, both polyester fiber and nylon fiber have excellent wear-resistant and tensile-resistant properties. After being woven into the outer sheath 3, the outer sheath 3 has extremely high strength and tensile properties while maintaining light weight. At the same time, it can further enhance the wear resistance of the cylindrical belt body on which the outer sheath 1 is installed, can help the cylindrical belt body 1 reduce more friction and wear, and extend its service life.

[0027] Reference Figure 4 As shown, in this embodiment, the herringbone pattern is formed by the interweaving of six warp threads 231 and six weft threads 232. The six warp threads 231 of the herringbone pattern are all in a three-up-three-down structure at the positions where they overlap with each weft thread 232, and the six weft threads 232 of the herringbone pattern are also all in a three-up-three-down structure at the positions where they overlap with each warp thread 231, and the overlapping positions where the warp threads 231 are on top are warp tissue points. Specifically, the warp threads in the first column are warp tissue points at the overlapping positions with the weft threads in the fourth, fifth, and sixth rows; the warp threads in the second column are warp tissue points at the overlapping positions with the weft threads in the first, fifth, and sixth rows; the warp threads in the third column are warp tissue points at the overlapping positions with the weft threads in the first, second, and sixth rows; the warp threads in the fourth column are warp tissue points at the overlapping positions with the weft threads in the third, fourth, and fifth rows; the warp threads in the fifth column are warp tissue points at the overlapping positions with the weft threads in the second, third, and fourth rows; the warp threads in the sixth column are warp tissue points at the overlapping positions with the weft threads in the first, second, and third rows; through the design of the herringbone pattern, it helps to enhance the durability and anti-tensile properties of the outer sheath 2.

[0028] A number of hook surfaces of Velcro 7 are fixedly installed on the cylindrical belt body 1. Corresponding to the inner surface of the wear-resistant and tensile-resistant sheath 23, a number of loop surfaces of Velcro are provided. The wear-resistant and tensile-resistant sheath 23 is detachably connected to the hook surfaces of Velcro 7 on the cylindrical belt body 1 through the loop surfaces of Velcro, which is convenient for replacing the worn outer sheath 2, helps to maintain the performance of the cylindrical belt and extend its service life.

[0029] In this embodiment, the hook surfaces of Velcro 7 and the loop surfaces of Velcro are respectively sewn to the outer surface of the cylindrical belt body 1 and the inner cavity surface of the wear-resistant and tensile-resistant sheath 23 through cross-shaped sewing threads. When the sewing threads sew the hook surfaces of Velcro 7 and the loop surfaces of Velcro, so that they are fixedly connected to the outer surface of the cylindrical belt body 1 and the inner cavity surface of the wear-resistant and tensile-resistant sheath 23 respectively, the structural stability of the cylindrical belt body 1 and the wear-resistant and tensile-resistant sheath 23 can be further enhanced.

[0030] Reference Figure 1 As shown, the present utility model also provides a high-strength wear-resistant cylindrical belt, which can be used for hoisting operations. It includes a cylindrical belt body 1 and an outer sheath 2 detachably arranged on the outer periphery of the cylindrical belt body 1 as described above.

[0031] Specifically, hoisting components (not marked in the figure) are arranged at both ends of the cylindrical belt body 1. The hoisting components include fixing parts 3 fixedly arranged at both ends of the cylindrical belt body 1. A connecting part 4 is arranged at the upper end of the fixing part 3, and a lifting ring 5 is arranged on the connecting part 4; and the lifting ring 5 is rotatably connected to the fixing part 3 through the connecting part 4, which is convenient for the cylindrical belt body 1 not to twist in shape when the cylindrical belt body 1 is suspended, and improves the use stability of the cylindrical belt.

[0032] Among them, anti-slip sleeves 6 are sleeved on the lifting rings 5, and anti-slip convex lines (not marked in the figure) are arranged on the anti-slip sleeves 6. By arranging the anti-slip sleeves 6 on the lifting rings 5, the friction between the lifting rings 5 and the hoisting equipment can be enhanced. At the same time, the anti-slip convex lines are arranged to further increase the friction coefficient of the contact surface, effectively preventing the occurrence of slipping during hoisting, and improving the safety and reliability of the hoisting process.

[0033] Reference Figure 2 As shown, the cylindrical belt body 1 includes a load-bearing core 11 and a first strand 12 and a second strand 13 spirally and alternately wound outside the load-bearing core 11.

[0034] By spirally and alternately winding the first rope strand 12 and the second rope strand 13 around the outside of the load-bearing core 11, a stable structure of the cylindrical belt body 1 is formed, enhancing the structural stability of the cylindrical belt body. At the same time, wear-resistant coatings 8 are provided on the outer surfaces of the first rope strand 12 and the second rope strand 13, and tensile wires 14 are used to fill the gaps between the first rope strand 12 and the second rope strand 13, significantly improving the tensile and wear-resistant properties of the cylindrical belt and being beneficial to the extension of the service life.

[0035] The first rope strand 12 is twisted from a number of high-strength carbon fiber filaments, and the second rope strand 13 is twisted from a number of aramid fiber filaments. Due to the high strength and high modulus of the carbon fiber filaments, the first rope strand 12 has excellent tensile strength and stiffness. And the aramid fiber filaments also have excellent mechanical properties, providing good strength support for the second rope strand 13. Both carbon fiber and aramid fiber have good corrosion resistance and high-temperature resistance, and can adapt to various use environments.

[0036] Preferably, a waterproof coating (not shown in the figure) is provided on the outer surfaces of both the cylindrical belt body 1 and the outer sleeve 2. The main function of the waterproof coating is to prevent moisture from penetrating into the inside of the cylindrical belt body 1 and the outer sleeve 2, and can effectively avoid damage or performance degradation of the cylindrical belt body 1 and the outer sleeve 2 caused by moisture intrusion.

[0037] Reflective strips 9 and fluorescent strips 10 for warning during night operations are alternately arranged on the cylindrical belt body 1, which can enhance the visibility of the cylindrical belt in the night or low-light environment and improve the safety of night operations. The reflective strips 9 can reflect light under the illumination of light sources such as vehicle lights, forming an obvious warning effect; while the fluorescent strips 10 can absorb and emit visible light in the absence of light sources, playing a continuous warning role.
