Description

Technical Field

[0001] This utility model relates to the field of lifting belt technology, and in particular to a tear-resistant and deformation-resistant steel wire lifting belt. Background Technology

[0002] Steel wire conveyor belts are commonly used for transporting grain, goods, machinery, chemical products, or chemical materials. Their structure includes a core rubber, steel wire rope, cover rubber, and edge rubber. Existing steel wire conveyor belts have the following problems in practical applications: (1) The cover rubber of the steel wire conveyor belt is prone to aging and deformation due to the influence of temperature, light, and humidity, which affects the service life of the conveyor belt; (2) The rigidity and strength of the conveyor belt are insufficient. When the material distribution on the conveyor belt is uneven, the steel wire rope is subjected to different forces, which can lead to steel wire rope breakage and increase the risk of conveying. Therefore, it is necessary to develop a tear-resistant and deformation-resistant steel wire conveyor belt to address the above problems. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tear-resistant and deformation-resistant steel wire lifting belt to address the shortcomings of the existing technology. This lifting belt can prevent the steel wire rope from breaking and reduce the risk of conveying. It also greatly improves the anti-aging properties of the covering rubber and extends its service life.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A tear-resistant and deformation-resistant steel wire lifting belt includes a lifting belt body. The lifting belt body includes a lower cover rubber, a first reinforcing layer on the upper part of the lower cover rubber, a first core rubber layer on the upper part of the first reinforcing layer, a first steel wire rope layer longitudinally arranged inside the first core rubber layer, a second reinforcing layer on the upper part of the first core rubber layer, a second core rubber layer on the upper part of the second reinforcing layer, a second steel wire rope layer transversely arranged inside the second core rubber layer, a third reinforcing layer on the upper part of the second core rubber layer, an upper cover rubber on the upper part of the third reinforcing layer, a waterproof coating on the upper part of the upper cover rubber, and an anti-aging coating on the upper part of the waterproof coating.

[0006] As an improved technical solution, the first reinforcing layer is a steel wire mesh layer.

[0007] As an improved technical solution, the second reinforcing layer is an aramid fiber layer.

[0008] As an improved technical solution, the third reinforcing layer is a polyester fiber layer.

[0009] As an improved technical solution, each wire rope in the first wire rope layer and the second wire rope layer is provided with a fabric wrapping layer on the outside.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are:

[0011] The tear-resistant and deformation-resistant lifting belt includes a lifting belt body, which comprises a lower cover rubber, a first reinforcing layer on top of the lower cover rubber, a first core rubber layer on top of the first reinforcing layer, a first steel wire rope layer longitudinally arranged inside the first core rubber layer, a second reinforcing layer on top of the first core rubber layer, a second core rubber layer on top of the second reinforcing layer, a second steel wire rope layer transversely arranged inside the second core rubber layer, a third reinforcing layer on top of the second core rubber layer, an upper cover rubber on top of the third reinforcing layer, a waterproof coating on top of the upper cover rubber, and an anti-aging coating on top of the waterproof coating. The lifting belt incorporates the first, second, and third reinforcing layers, which work synergistically to further improve the strength and rigidity of the lifting belt. The longitudinal arrangement of the first steel wire rope layer and the transverse arrangement of the second steel wire rope layer help the lifting belt maintain better shape stability during operation, reducing deformation and twisting caused by uneven stress or external factors, resulting in smoother operation. The waterproof coating on the upper cover rubber prevents moisture damage to the lifting belt, and the anti-aging coating reduces the damage caused by sunlight. The above-mentioned structure has a reasonable design for the lifting belt, which greatly improves the strength and load-bearing capacity of the lifting belt, effectively solves the problems of wire rope breakage when the force is uneven and the aging and damage of the lifting belt, and greatly extends the service life of the lifting belt.

[0012] Because the first reinforcing layer is a steel wire mesh layer, this design acts as a skeleton support, capable of bearing the weight of the material and increasing the tension during belt operation, preventing the belt from breaking under large tensile forces.

[0013] Because the second reinforcing layer is an aramid fiber layer, it has extremely high strength and modulus, several times stronger than steel wire. It can maintain stable performance in high-temperature environments, and also has good flame retardancy and chemical corrosion resistance, extending the service life of the lifting belt.

[0014] Because the third reinforcing layer is a polyester fiber layer, it has high strength and modulus, good wear resistance, excellent tensile properties, and can withstand large loads, greatly improving the strength of the conveyor belt and extending its service life.

[0015] Because each wire rope in the first and second wire rope layers is covered with a fabric layer, the high strength and load-bearing capacity of the wire rope can be utilized, while the fabric layer can improve the surface wear resistance and corrosion resistance of the hoisting belt.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] A tear-resistant and deformation-resistant steel wire lifting belt, such as Figure 1 As shown, the conveyor belt includes a lifting belt body 1, which includes a lower cover rubber 10. The upper part of the lower cover rubber 10 is provided with a first reinforcing layer 11 (steel wire mesh layer). The upper part of the first reinforcing layer 11 is provided with a first core rubber layer 12. The interior of the first core rubber layer 12 is provided with a first steel wire rope layer 13 longitudinally. The upper part of the first core rubber layer 12 is provided with a second reinforcing layer 14 (aramid fiber layer). The upper part of the second reinforcing layer 13 is provided with a second core rubber layer 15. The interior of the second core rubber layer 15 is provided with a second steel wire rope layer 16 transversely. The upper part of the second core rubber layer 15 is provided with a third reinforcing layer 17 (polyester fiber layer). The upper part of the third reinforcing layer 16 is provided with a rubber upper cover rubber 18. The upper part of the upper cover rubber 18 is provided with a waterproof coating 180 (organic silicone coating layer). The upper part of the waterproof coating 180 is provided with an anti-aging coating 181 (composed of a mixture of ultraviolet absorber, antioxidant and acrylic resin).

[0020] The conveyor belt comprises a first reinforcing layer (a steel wire mesh layer, acting as a skeleton to support the material and withstand the tension of the conveyor belt during operation, preventing breakage under high tensile forces), a second reinforcing layer (an aramid fiber layer, possessing extremely high strength and modulus, several times stronger than steel wire, maintaining stable performance at high temperatures, and also exhibiting good flame retardancy and chemical corrosion resistance), and a third reinforcing layer (a polyester fiber layer, possessing high strength and modulus, good wear resistance, and excellent tensile strength, capable of withstanding large loads, significantly improving the strength of the conveyor belt). The synergistic effect of these three reinforcing layers further enhances the strength and rigidity of the conveyor belt. The first steel wire rope layer is arranged longitudinally, and the second steel wire rope layer is arranged transversely, helping the conveyor belt maintain better shape stability during operation, reducing deformation and twisting caused by uneven stress or external factors, resulting in smoother operation. A waterproof coating on the top cover protects the conveyor belt from moisture damage, while an anti-aging coating reduces the damage caused by sunlight. The above-mentioned structure has a reasonable design for the lifting belt, which greatly improves the strength and load-bearing capacity of the lifting belt, effectively solves the problems of wire rope breakage when the force is uneven and the aging and damage of the lifting belt, and greatly extends the service life of the lifting belt.

[0021] Each wire rope in the first wire rope layer 13 and the second wire rope layer 16 is provided with a fabric wrapping layer 19 (composed of metal wires and glass fiber). By providing the fabric wrapping layer, the high strength and load-bearing capacity of the wire rope can be utilized, while the surface wear resistance and corrosion resistance of the hoisting belt can be improved through the fabric layer.

[0022] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
