Description

Technical Field

[0001] This application relates to the field of reinforcing the connection between goods and the vehicle body in the transportation loading field, and specifically to a steel wire rope quick tightening connector. Background Technology

[0002] According to the national logistics development plan, the optimization of the transportation structure and the continuous advancement of the "road-to-rail" model for bulk commodity transportation will bring great development opportunities to railway transportation.

[0003] The requirements for loading and securing goods in railway transportation are extremely stringent. A cargo transshipment and securing plan must be developed based on the specific goods being transported, and this plan must be strictly followed during the loading process. In particular, when loading large-tonnage goods onto railway flatcars, steel cables are often used to secure the goods to the carriages. According to railway transportation agreements, loading and securing operations must be completed within four hours.

[0004] Currently, the common method for securing goods involves using steel wire ropes with traditional wire rope clamps. This involves first fixing one end of the wire rope, then temporarily securing the other end with a wire rope clamp using a loop. A chain hoist is then used to pull this end, tightening it, and finally securing the two different wire ropes with at least three wire rope clamps. The rope used for the loop is then cut off. In practice, this method is not only cumbersome, time-consuming, and labor-intensive, but it is also limited by the length of the wire rope, restricting its effectiveness in certain locations. Furthermore, the waste of cutting off the wire rope used for the loop is also a problem. Summary of the Invention

[0005] This application provides a quick-tightening connector for steel wire ropes, which can solve the problems of cumbersome, time-consuming, and labor-intensive operation of binding and reinforcing goods with steel wire ropes in the prior art, and the easy waste of steel wire ropes.

[0006] This application provides a quick-tightening connector for steel wire rope, comprising: a main body having a first through hole along its length for a steel wire rope to pass through, and a plurality of second through holes communicating with the first through hole evenly formed on one side wall of the main body, the plurality of second through holes being arranged along the length of the main body, and fasteners for fastening the steel wire rope being provided in the second through holes; and a retaining ring for locking a loop of another steel wire rope, the retaining ring being located at one end of the first through hole and being held in place by two opposite outer side walls of the main body, wherein the two outer side walls are not provided with second through holes.

[0007] In some embodiments, the fastener is threadedly connected to the second through hole.

[0008] In some embodiments, a boss extends outward from the side wall of the main body at the port of the second through hole, the fastener has an external thread, and the boss has an internal thread hole that mates with the thread of the fastener.

[0009] In some embodiments, the fastener is a high-strength bolt.

[0010] In some embodiments, both the second through hole and the internal threaded hole are filled with lubricating oil.

[0011] In some embodiments, a gasket is provided between the fastener and the port of the boss.

[0012] In some embodiments, the retaining ring is a U-shaped structure, with its two arms fixed to opposite sidewalls of the main body, and the retaining ring is positioned close to the second through hole.

[0013] In some embodiments, the body and the retaining ring are fixed by welding.

[0014] In some embodiments, the surfaces of the body, the fastener, and the retaining ring are all coated with an anti-corrosion coating.

[0015] In some embodiments, the inner wall of the first through hole that contacts the wire rope is provided with an anti-slip layer.

[0016] The beneficial effects of the technical solutions provided in this application include: In this application, the wire rope quick-tightening connector is mainly used for binding and reinforcing goods. The rope sleeve of one wire rope passes through the shackle and is fixed to the main body of the wire rope quick-tightening connector. The end of the other wire rope passes through the first through hole. The goods are bound by continuously tightening the wire rope in the first through hole. After ensuring that the goods are bound tightly, fasteners are used to continuously squeeze and fix the wire rope in the second through hole through the second through hole, so that the wire rope is firmly fixed in the first through hole.

[0017] By evenly opening several second through holes communicating with the first through hole on one side wall of the main body, and arranging the several second through holes along the length of the main body, and providing fasteners for fastening the wire rope in the second through holes, the wire rope can be tightened quickly, saving the length of the wire rope used and reducing costs.

[0018] By locking the loop of the other wire rope with a snap ring, the wire rope can be quickly tightened, and the tightening position can be fixed without restriction, offering greater flexibility. By placing the snap ring at one end of the first through hole, the force direction of both wire ropes is ensured to be consistent. The snap ring is held in place on two opposite outer walls of the main body, and these outer walls do not have second through holes. This ensures that the wire rope located in the first through hole is not affected by the snap ring during tightening. In summary, this embodiment solves the problems of cumbersome, time-consuming, and labor-intensive wire rope binding and reinforcement operations in existing technologies, which also easily lead to wire rope waste.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0023] This application provides a quick-tightening connector for steel wire ropes, which can solve the problems of cumbersome, time-consuming, and labor-intensive operation of binding and reinforcing goods with steel wire ropes in the prior art, and the easy waste of steel wire ropes.

[0024] See Figure 1 , Figure 1 This is a schematic diagram of a quick-tightening connector for a wire rope in an embodiment of this application. Figure 1As shown, in one embodiment, the wire rope quick-tightening connector includes a main body 1 and a retaining ring 3. The retaining ring 3 is fixedly connected to the main body 1. The main body 1 and the retaining ring 3 respectively fix two different wire ropes. The wire rope fixed by the main body 1 can be adjusted in its fixed position, while the wire rope fixed by the retaining ring 3 cannot be adjusted in its fixed position. Specifically, the main body 1 can be a rectangular tube or a round tube. A first through hole 11 is provided along the length of the main body 1, through which the wire rope can pass. Several second through holes 12 communicating with the first through hole 11 are evenly provided on one side wall of the main body 1. The several second through holes 12 are arranged along the length of the main body 1. If there are two second through holes 12, the two second through holes 12 are located at the two ends of the main body 1 respectively. If there are three or more second through holes 12, a certain distance is maintained between each second through hole 12, and they are evenly arranged along the length of the main body 1. It should be noted that the number of second through holes 12 needs to be reasonably set according to the length of the main body 1. A fastener 2 is provided inside the second through hole 12. When the wire rope passes through the first through hole 11 and its position needs to be fixed, the fastener 2 can be used to fix the wire rope inside the first through hole 11. The retaining ring 3 is a ring structure, mainly used to fix the loop of another wire rope. The retaining ring 3 is located at one end of the first through hole 11 and is held in place by two opposite side walls of the main body 1. These two outer side walls do not have the second through hole 12. The retaining ring 3 is tightly fixed to the main body 1 to ensure that it will not suddenly disconnect during use.

[0025] In this embodiment, the wire rope quick-tightening connector is mainly used for binding and reinforcing goods. The rope sleeve of one wire rope passes through the shackle 3 and is fixed to the main body 1 of the wire rope quick-tightening connector. The end of the other wire rope passes through the first through hole 11. The wire rope is tightened by a chain hoist or a hand chain hoist to bind the goods. After ensuring that the goods are tightly bound, the fastener 2 passes through the second through hole 12 and continuously squeezes the wire rope in the second through hole 12, so that the wire rope is firmly fixed in the first through hole 11.

[0026] By uniformly opening a number of second through holes 12 that communicate with the first through hole 11 on one side wall of the main body 1, and the number of second through holes 12 arranged along the length of the main body 1, and the second through holes 12 are provided with fasteners 2 for fastening the wire rope, the wire rope can be tightened quickly, saving the length of the wire rope used and reducing costs.

[0027] By locking the loop of the other wire rope with the retaining ring 3, the wire rope can be quickly tightened, and the tightening position of the joint can be fixed without restriction, which is more flexible. By placing the retaining ring 3 at one end of the first through hole 11, it is ensured that the force direction of the two wire ropes is consistent, and the retaining ring 3 is held in place on the two opposite outer walls of the main body 1, and the two outer walls do not have second through holes 12. In this way, the wire rope located in the first through hole 11 will not be affected by the retaining ring 3 during the tightening process. In summary, this embodiment can solve the problems of cumbersome, time-consuming, and labor-intensive operation of binding and reinforcing goods with wire ropes in the prior art, and the easy waste of wire ropes.

[0028] Furthermore, in one embodiment, such as Figure 1 As shown, the fastener 2 is threadedly connected to the second through hole 12. In this embodiment, the threaded connection provides greater friction and tightening force, making it difficult for the fastener 2 to loosen or fall out within the second through hole 12. When it is necessary to tighten the wire rope, by rotating the fastener 2, its threads engage with the threads of the second through hole 12, generating sufficient axial force to firmly fix the wire rope in place. This ensures that the wire rope will not move or slip due to force during use, guaranteeing overall stability and safety. Furthermore, installing and removing the wire rope is also relatively convenient.

[0029] Furthermore, in one embodiment, such as Figure 1 As shown, a boss 13 extends outward from the side wall of the main body 1 at the port of the second through hole 12. The fastener 2 has external threads, and the boss 13 has an internal threaded hole that mates with the fastener 2. In this embodiment, the boss 13 increases the effective length of the threaded connection, thereby increasing the threaded contact area between the fastener 2 and the main body 1. A larger contact area can withstand greater tensile and shear forces, thus improving the strength and load-bearing capacity of the entire connection and ensuring that the fastener 2 will not easily loosen or come off the main body 1 when the wire rope is subjected to greater tension. In addition, when the wire rope is under stress, the force is transmitted to the main body 1 through the fastener 2, and the force is concentrated at the port of the second through hole 12, which can easily lead to stress concentration at this location, thereby causing fatigue failure or crack propagation of the material.

[0030] Furthermore, in one embodiment, such as Figure 1 As shown, fastener 2 is a high-strength bolt. In this embodiment, since high-strength bolts are significantly superior to ordinary bolts in terms of high load bearing capacity, fatigue resistance, corrosion resistance, and structural compactness, using high-strength bolts as fastener 2 can improve the overall safety, durability, and ease of maintenance of the wire rope quick-tightening joint.

[0031] Furthermore, in one embodiment, such as Figure 1As shown, both the second through hole 12 and the internal threaded hole are filled with lubricating oil. In this embodiment, through the above technical solution, when installing the fastener 2, the lubricating oil can reduce the friction between the external and internal threads of the fastener 2, making the fastener 2 easier to screw in. In addition, the lubricating oil can form a protective film on the metal surface, preventing air, moisture and other corrosive substances from contacting the metal, thereby preventing rust on the surfaces of the second through hole 12 and the internal threaded hole, improving the corrosion resistance of the parts, and ensuring good performance under various working environments.

[0032] Furthermore, in one embodiment, such as Figure 1 As shown, a gasket 14 is provided between the fastener 2 and the port of the boss 13. In this embodiment, the gasket 14 can increase the contact area between the fastener 2 and the port of the boss 13. When tightening the fastener 2, the gasket 14 can evenly distribute the tightening force to the surrounding area of ​​the port of the boss 13, avoiding excessive local pressure. This helps to prevent the port of the boss 13 from deforming or being damaged due to excessive pressure, thus extending the service life of the boss 13. In addition, it can reduce stress concentration and lower the risk of cracks or other damage to the boss 13.

[0033] Furthermore, in one embodiment, such as Figure 1 As shown, the retaining ring 3 has a U-shaped structure, with its two arms fixed to opposite sidewalls of the main body 1. The retaining ring 3 is positioned near the second through hole 12. In this embodiment, the above-mentioned technical solution can effectively secure the wire rope with the rope loop. Simultaneously, it also prevents the retaining ring 3 from obstructing the tightening of the wire rope located within the first through hole 11.

[0034] Furthermore, in one embodiment, such as Figure 1 As shown, the main body 1 and the retaining ring 3 are fixed together by welding. In this embodiment, by fixing the main body 1 and the retaining ring 3 by welding, the main body 1 and the retaining ring 3 can withstand greater tensile force, making it less likely to loosen or fall off, thus ensuring the stability of the connection between the main body 1 and the retaining ring 3.

[0035] Furthermore, in one embodiment, such as Figure 1 As shown, the surfaces of the main body 1, fastener 2, and retaining ring 3 are all coated with an anti-corrosion coating. In this embodiment, the anti-corrosion coating separates the metal from air and water, preventing the metal from undergoing an oxidation reaction with oxygen, thereby avoiding rust. For example, in a humid environment, the steel main body 1, fastener 2, and retaining ring 3 without coating protection are prone to developing reddish-brown rust, while the coating protection can effectively delay this process.

[0036] Furthermore, in one embodiment, such as Figure 1As shown, the inner wall of the first through hole 11 in contact with the wire rope is provided with an anti-slip layer. In this embodiment, by providing an anti-slip layer on the inner wall of the first through hole 11 in contact with the wire rope, the friction between the wire rope and the inner wall of the first through hole 11 can be increased, so that the wire rope will not easily come out of the first through hole 11 when subjected to a large tension.
