Description

Technical Field

[0001] This utility model relates to the field of wire rope technology, specifically a wear-resistant and corrosion-resistant pressed wire rope. Background Technology

[0002] A wire rope is a type of rope made of multiple twisted steel wires, primarily made of steel wire, typically carbon steel or alloy steel. These wires are twisted together using a special process and following specific rules. Wire ropes possess advantages such as high strength, light weight, stable operation, and resistance to sudden breakage. Therefore, they are widely used in many fields, including cranes for lifting heavy objects in construction, elevators for suspending the car and ensuring safe lifting, and mine hoisting equipment.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN222226920U) discloses a steel wire rope, comprising a first rope body and a second rope body. The first rope body has multiple strands that are circumferentially wound around the outside of the second rope body. The ends of the multiple first rope bodies are fixed to a fastening device. The fastening device has threads on its inner diameter, which engage with the threads on the outer circumference of the extension of the second rope body. By rotating the fastening device, the first rope bodies circumferentially wound around the outside of the second rope body can be made more secure, avoiding the reduction in the toughness of the steel wire rope due to the loosening of the first rope body. Furthermore, the arrangement of multiple rope bodies allows the second rope body to bear the load in the event of a breakage of the first rope body, reducing the risk of steel wire rope breakage.

[0004] Although the aforementioned patent improves the rope's friction by using a rotating tightening device and its internal threads, and by having the extended end of the second rope engage with the threads in the tightening device to prevent the rope from loosening and reducing the toughness of the wire rope, and by using the first and second ropes to prevent the load from falling due to the breakage of a single rope, during the use of the wire rope, frequent lifting often causes the internal strands to rub against each other. When this friction is frequent, it can easily cause the wire rope to break. Furthermore, during frequent lifting, the wire rope is frequently tensioned, making it more prone to fatigue damage and accelerating wear. When lifting heavy objects, the wire rope is subjected to the pulling force of gravity, making it more likely to break due to tension, which is detrimental to improving the service life of the wire rope.

[0005] Therefore, this utility model provides a wear-resistant and corrosion-resistant pressed steel wire rope to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a wear-resistant and corrosion-resistant pressed steel wire rope, aiming to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A wear-resistant and corrosion-resistant pressed steel wire rope includes a rope body, a rope clip fixedly sleeved on the outer wall of the rope body, and a rope core assembly disposed inside the rope body.

[0011] The rope core assembly includes a placement groove inside the rope body, a prestressing tendon is fixedly connected inside the placement groove, a plurality of friction grooves are formed on the outer wall of the prestressing tendon, a reserved groove is formed inside the prestressing tendon, and a plurality of steel balls are filled inside the reserved groove.

[0012] As a preferred technical solution of this application, a plurality of rope strands are fixedly connected to the outer wall of the rope, and the plurality of rope strands are tightly wound around the outer wall of the rope, and the outer wall of the rope strands is coated with lubricating oil.

[0013] As a preferred technical solution of this application, the end of the rope body is fixedly connected to a reinforcing rope segment inside the rope clamp, and the outer wall of the reinforcing rope segment is coated with an anti-corrosion and wear-resistant coating.

[0014] As a preferred technical solution of this application, the outer wall of the rope strand is fixedly sleeved with a plurality of rope binding sleeves to improve the tightness of the wire rope, and the inner wall of the rope binding sleeves is concave and convex.

[0015] As a preferred technical solution of this application, an oil storage groove is provided on the side of the rope strand close to the prestressing tendon, and the inner wall of the oil storage groove is filled with fiber material.

[0016] As a preferred technical solution of this application, the end of the rope is fixedly sleeved with an abutment plate, the end of the abutment plate is provided with a plurality of rope-locking grooves, the ends of the rope strands are locked in the rope-locking grooves, and the outer wall of the abutment plate is coated with a waterproof coating.

[0017] (III) Beneficial Effects

[0018] By setting up a rope core assembly, the impact of the tension of heavy objects on the wire rope can be reduced. Through the pre-set prestressing tendons, prestress is applied in advance, creating an inward pulling force inside the rope core. When lifting heavy objects, the tension can be maintained by multiple strands at the outer end of the wire rope, while the inward prestressing can offset part of the gravity. The friction grooves opened on the outer wall of the prestressing tendons will increase the friction between the rope and the outer wall when lifting heavy objects, further reducing the wear of the wire rope and increasing its service life.

[0027] 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.

[0028] This utility model provides a wear-resistant and corrosion-resistant pressed steel wire rope, such as... Figures 1-6 As shown, the wear-resistant and corrosion-resistant pressed steel wire rope includes a rope body 1, a rope clip 2 is fixedly sleeved on the outer wall of the rope body 1, and a rope core assembly is provided inside the rope body 1.

[0029] The rope core assembly includes a placement groove 3 inside the rope body 1, a prestressing tendon 4 fixedly connected inside the placement groove 3, a plurality of friction grooves 5 on the outer wall of the prestressing tendon 4, a reserved groove 6 inside the prestressing tendon 4, and a plurality of steel balls 7 filled inside the reserved groove 6.

[0030] Multiple rope strands 8 are fixedly connected to the outer wall of the rope body 1, and the multiple rope strands 8 are tightly wrapped around the outer wall of the rope body 1, and the outer wall of the rope strands 8 is coated with lubricating oil.

[0031] The end of the rope body 1 is fixedly connected to a reinforcing rope segment 9 inside the rope clip 2. The outer wall of the reinforcing rope segment 9 is coated with an anti-corrosion and wear-resistant coating.

[0032] Multiple rope-binding sleeves 10 are fixedly sleeved on the outer wall of the rope strand 8 to improve the tightness of the wire rope. The inner wall of the rope-binding sleeve 10 is concave and convex.

[0033] Specifically, by fixing rope clamps 2 to the outer wall of the rope body 1, the wire rope can be tightly secured, preventing loosening at the connection points during lifting and improving the safety of the wire rope. The rope core assembly, through the cooperation of various components, reduces some of the weight's impact on the wire rope, improving its wear resistance. When the wire rope lifts a heavy object, because the rope core assembly has multiple placement grooves 3, and prestressing tendons 4 are installed inside the grooves 3, the tension of the heavy object on the wire rope will be reduced by the prestressing tendons. The tension rebound force of the rib 4 partially offsets this, and the multiple friction grooves 5 on the outer wall of the prestressed rib 4 enhance the friction with the rope 1 during hoisting, thereby improving the tightness of the connection. The reserved groove 6 inside the rib 4, and the steel balls 7 inside the reserved groove 6, allow the steel balls 7 to move to the bottom of the wire rope by gravity during use. This method pre-straightens the wire rope, preventing damage caused by the sudden straightening of a bent wire rope during use. To reduce its wear resistance, the tightly wound multiple strands 8 on the outer wall of the rope body 1 further improve the tensile strength of the wire rope. The lubricating oil coated on its outer wall reduces the friction of the wire rope during use, and because the lubricating oil coats the wire rope, it can prevent external environmental pollutants from damaging the wire rope, thus improving its corrosion resistance. The reinforcing rope section 9 at the end of the rope body 1 facilitates the attachment of the wire rope to the lifting equipment. The wear-resistant coating on its outer wall further enhances its wear resistance. The high corrosion resistance of the steel wire rope is achieved by using the rope binding sleeve 10 on the outer wall of the strand 8 to secure the steel wire rope, preventing the strand 8 from loosening outward due to tension when lifting heavy objects. The concave-convex inner wall also increases the friction with the strand 8. This component has a simple structure. By setting multiple prestressing ribs 4 inside the rope body 1, the strength of the steel wire rope can be improved, and the prestress of the prestressing ribs 4 can offset part of the tension brought by the weight. It is highly practical and helps to improve the service life of the steel wire rope.

[0034] An oil storage groove 11 is provided on the side of the rope strand 8 close to the prestressing tendon 4, and the inner wall of the oil storage groove 11 is filled with fiber material.

[0035] A stop plate 12 is fixedly sleeved at the end of the rope body 1. Multiple rope-locking grooves 13 are opened at the end of the stop plate 12. The ends of the rope strands 8 are locked in the rope-locking grooves 13. The outer wall of the stop plate 12 is coated with waterproof paint.

[0036] Specifically, the wire rope 8 has an oil storage groove 11 inside, which allows the wire rope to be soaked in lubricating oil before use. The fibrous material inside the oil storage groove 11 fully absorbs the lubricating oil. During later use, the weight of the hoisting forces the lubricating oil in the groove to overflow, thus lubricating the wire rope from the inside and improving its wear resistance. The abutment plate 12 at the end of the rope body 1 provides a limit to the rope body 1 through the rope clamping groove 13 inside the abutment plate 12, preventing the wire rope from loosening during hoisting.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
