Description

Technical Field

[0001] This utility model relates to the field of steel wire rope splicing technology, and in particular to a steel wire rope that is easy to splice. Background Technology

[0002] Steel cables are subjected to alternating loads during use, and their performance is mainly determined by the mechanical properties, surface condition, and structure of the cable. The cable material includes carbon steel or alloy steel, produced by cold drawing or cold rolling. The cross-section of the cable can be circular or irregular (T-shaped, S-shaped, Z-shaped). Irregularly shaped cross-section cables are mainly used in the production of sealed steel cables, possessing higher tensile strength and toughness. Appropriate surface treatments are then applied to the cables to meet the requirements of different operating environments.

[0003] The existing patent publication number CN202220096442.0 discloses a splicable steel cable, including a connecting post and a nut. One end of the connecting post is fixedly connected to a bolt C, and the other end is fixedly connected to a connecting box A. A baffle A is movably connected to the top of the connecting box A. A bolt A is fixedly connected inside the connecting box A, and a nut A is threaded onto the outside of the bolt A. One end of the connecting box A has a slot A, and a first steel cable is movably connected inside the slot A. One end of the nut has internal threads, and the other end is fixedly connected to a connecting box B. One end of the connecting box B has a slot B, and a second steel cable is movably connected inside the slot B. The first steel cable is movably connected inside the connecting box A, facilitating the interconnection of multiple steel cables and increasing the flexibility of the cable connection. The bolt C and nut ensure a tighter connection between the steel cables, preventing safety hazards caused by breaks or loose connections at the cable joints.

[0004] Currently, the connection process exhibits instability. At the splicing points, under complex operating conditions such as vibration and stress concentration, the connecting components are prone to loosening. This loosening leads to uneven load distribution at the steel cable connection points during operation, subjecting them to repeated additional alternating stress. Prolonged exposure to this abnormal stress state causes cumulative damage to the microstructure of the metal material at the steel cable connection points, accelerating the initiation and propagation of fatigue cracks, significantly reducing the fatigue life of the steel cable connection points, and seriously affecting the reliability and safety of the overall structure. Therefore, we propose an easily spliced ​​steel wire rope to address the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this invention is to provide an easily spliced ​​steel wire rope that solves the problem of poor stability in current connection links. At the splicing points, due to complex working conditions such as vibration and stress concentration, the connecting components are prone to loosening. This loosening at the splice leads to uneven load distribution at the steel cable connection points during operation, subjecting them to repeated additional alternating stress. Prolonged exposure to this abnormal stress state causes cumulative damage to the microstructure of the metal material at the steel cable connection points, accelerating the initiation and propagation of fatigue cracks, significantly reducing the fatigue life of the steel cable connection points, and seriously affecting the reliability and safety of the overall structure. Therefore, we propose an easily spliced ​​steel wire rope to solve the aforementioned problems.

[0007] To solve the above-mentioned technical problems, this utility model provides an easy-to-assemble steel wire rope, which adopts the following technical solution: it includes two steel wire rope bodies, and a snap-fit ​​structure is provided between the two steel wire rope bodies. The snap-fit ​​structure is also provided with a fixing structure at both ends.

[0008] The fixing structure includes a first slot plate, with a steel wire rope body inserted at one end of the first slot plate away from the snap-fit ​​structure. Threaded holes are provided at the top and bottom of the first slot plate, and a positioning screw is threadedly connected inside each of the two threaded holes. The bottom end of the positioning screw passes through the threaded hole and abuts against the surface of the steel wire rope body.

[0009] The snap-fit ​​structure includes a second fixed post, a movable connecting post, and a third fixed post. The second fixed post is fixedly installed at the end of the first slot plate away from the wire rope body. The third fixed post is fixedly installed at the end of the second fixed post away from the first slot plate. A movable connecting post is also slidably arranged outside the second fixed post. The movable connecting post and the second fixed post have the same structure, and the movable connecting post and the second fixed post are distributed in a mirror image on the surface of the second fixed post.

[0010] Optionally, the snap-fit ​​structure further includes a connecting sleeve, with snap-fit ​​posts inserted into the upper and lower sides of both ends of the connecting sleeve, and a limit plate fixedly provided at the end of each snap-fit ​​post away from the connecting sleeve.

[0011] Optionally, each of the slot posts has a snap-fit ​​plate fixedly installed at one end inside the connecting sleeve, and each of the slot posts is fitted with a spring, which is located between the snap-fit ​​plate and the inner wall of the connecting sleeve.

[0012] Optionally, the first slot plate has a groove that matches the shape of the wire rope body, and the wire rope body is fixed inside the groove by a positioning screw.

[0013] Optionally, the spring is a stainless steel compression spring.

[0014] Optionally, the snap-fit ​​structure is made of aluminum alloy.

[0015] In summary, this utility model has at least one of the following beneficial effects: 1. The fixing structure, through the cooperation of the first slot plate and the positioning screw, firmly fixes the wire rope body, preventing displacement at the splicing point. In the snap-fit ​​structure, the second fixing post, the movable connecting post, and the third fixing post cooperate with each other, along with the connecting sleeve, the slot post, and other components, forming multiple stable connections. This effectively resists complex working conditions such as vibration and stress concentration, prevents loosening of connecting components, makes the load distribution at the splicing point more uniform, greatly reduces the risk of fatigue cracks, and significantly improves the fatigue life of the wire rope splicing point as well as the reliability and safety of the overall structure.

[0016] 2. The snap-fit ​​structure is made of aluminum alloy, which is lightweight and corrosion-resistant, and can maintain stable performance in a variety of harsh environments; the spring is made of stainless steel compression spring, which has good corrosion resistance and elasticity, ensuring long-term stable operation of the snap-fit ​​structure and reducing maintenance and replacement costs caused by component damage.

[0023] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0024] Example 1, refer to Figure 1-4 In this embodiment, to address the current issue of poor stability in the connection links, the connecting components at the splicing points are prone to loosening due to complex working conditions such as vibration and stress concentration. This loosening leads to uneven load distribution at the steel cable connection points during operation, subjecting them to repeated alternating stresses. Prolonged exposure to this abnormal stress state causes cumulative damage to the microstructure of the metal material at the steel cable connection points, accelerating the initiation and propagation of fatigue cracks, significantly reducing the fatigue life of the steel cable connection points, and seriously affecting the reliability and safety of the overall structure. Therefore, we propose an easily spliced ​​steel wire rope to solve the aforementioned problems. This utility model discloses an easily spliced ​​steel wire rope.

[0025] It includes two sections of wire rope body 102, and a snap-fit ​​structure 1 is provided between the two sections of wire rope body 102. The snap-fit ​​structure 1 is also provided with a fixing structure 2 at both ends.

[0026] The fixing structure 2 includes a first slot plate 101. A wire rope body 102 is inserted into one end of the first slot plate 101 away from the snap-fit ​​structure 1. Threaded holes 103 are provided at the top and bottom of the first slot plate 101. Positioning screws 104 are threadedly connected inside the two threaded holes 103. The bottom end of the positioning screws 104 passes through the threaded holes 103 and abuts against the surface of the wire rope body 102.

[0027] The snap-fit ​​structure 1 includes a second fixed post 201, a movable connecting post 202, and a third fixed post 203. The second fixed post 201 is fixedly installed at one end of the first slot plate 101 away from the wire rope body 102. The third fixed post 203 is fixedly installed at the other end of the second fixed post 201 away from the first slot plate 101. The movable connecting post 202 is also slidably arranged on the outside of the second fixed post 201. The movable connecting post 202 and the second fixed post 201 have the same structure, and the movable connecting post 202 and the second fixed post 201 are distributed in a mirror image on the surface of the second fixed post 201.

[0028] Specifically, when it is necessary to fix the wire rope body 102 to the first slot plate 101, first align one end of the wire rope body 102 with the slot opened in the first slot plate 101 and insert it. Then, the operator uses a matching tool, such as a screwdriver, to tighten the positioning screw 104. Since the threaded hole 103 and the positioning screw 104 are connected by threads, as the screw rotates, it moves axially along the threaded hole 103. Until the bottom end of the positioning screw 104 is tightly pressed against the surface of the wire rope body 102, by increasing the friction between the two, the wire rope body 102 is prevented from moving within the first slot plate 101, thereby achieving stable positioning of the wire rope at one end of the fixed structure 2. The second fixing post 201, as the core connecting component, has one end firmly fixedly connected to the first slot plate 101, ensuring reliable connection between the clamping structure 1 and the fixed structure 2. At the other end of the second fixing post 201, the third fixing post 203 is also fixedly installed, forming a stable connection combination with the second fixing post 201. The movable connecting post 202 is sleeved outside the second fixed post 201 and can slide along the axial direction of the second fixed post 201. Because the movable connecting post 202 and the second fixed post 201 have the same structure and are mirror images of each other, they can provide a symmetrical and stable support structure for subsequent connections with other components when they are in contact, thus optimizing the force distribution during splicing.

[0029] The snap-fit ​​structure 1 also includes a connecting sleeve 204. Both ends of the connecting sleeve 204 are provided with slotted posts 205 on the upper and lower sides. Each slotted post 205 is fixedly provided with a limit plate 206 at the end away from the connecting sleeve 204.

[0030] Specifically, the connecting sleeve 204, as a key component of the snap-fit ​​structure 1 for achieving the splicing function, has through holes on both its upper and lower ends for the insertion of the slotted post 205. A limiting plate 206 is fixed to one end of the slotted post 205; the diameter of the limiting plate 206 is larger than the diameter of the through hole on the connecting sleeve 204, preventing the slotted post 205 from falling out of the connecting sleeve 204. During the splicing process, the slotted post 205, using the connecting sleeve 204 as a carrier, can quickly connect with the corresponding external structure, providing guidance and positioning for the splicing of the wire rope.

[0031] Each slot post 205 has a snap-fit ​​plate 207 fixedly installed at one end inside the connecting sleeve 204, and each slot post 205 is fitted with a spring 208 on the outside, with the spring 208 located between the snap-fit ​​plate 207 and the inner wall of the connecting sleeve 204.

[0032] Specifically, the slotted post 205 is fixedly connected to a snap-fit ​​plate 207 at one end inside the connecting sleeve 204. The snap-fit ​​plate 207 increases the contact area with the spring 208, ensuring the uniform transmission of the force exerted by the spring 208. The spring 208 is sleeved on the outside of the slotted post 205, with its two ends abutting against the snap-fit ​​plate 207 and the inner wall of the connecting sleeve 204, respectively. During the splicing process, when the slotted post 205 is subjected to external compression or tension, the snap-fit ​​plate 207 will move accordingly, compressing or stretching the spring 208. The elastic force generated by the spring 208 will then act in the opposite direction on the snap-fit ​​plate 207, thereby providing a fine-tuning and buffering effect on the position of the slotted post 205, ensuring that the snap-fit ​​structure 1 can always fit tightly with the external structure under different working conditions, maintaining the stability of the wire rope splicing part.

[0033] The first slot plate 101 has a groove 105 that matches the shape of the wire rope body 102, and the wire rope body 102 is fixed inside the groove 105 by a positioning screw 104.

[0034] Specifically, the first slot plate 101 is a rectangular metal plate. On one side surface, a semi-circular groove 105 is machined to perfectly match the diameter and shape of the wire rope body 102. When the wire rope body 102 is placed in the groove 105, it fits tightly, restricting the horizontal displacement of the wire rope. Threaded holes 103 are drilled at the top and bottom of the first slot plate 101, corresponding to the positions of the groove 105. A positioning screw 104 is screwed into the threaded hole 103. When the positioning screw 104 is rotated, its bottom end gradually descends until it presses tightly against the surface of the wire rope body 102, using friction to prevent the wire rope from moving up and down within the groove 105, thus achieving a stable fixation of the wire rope.

[0035] Spring 208 is a stainless steel compression spring 208;

[0036] Specifically, the stainless steel compression spring 208 is made of high-quality stainless steel, which has good corrosion resistance and can be used in harsh environments such as humid and acidic / alkaline conditions, effectively preventing the spring 208 from failing due to corrosion.

[0037] The snap-fit ​​structure 1 is made of aluminum alloy;

[0038] Specifically, the aluminum alloy used in the snap-fit ​​structure 1 is made of aluminum as a base, with appropriate amounts of other alloying elements added. Aluminum alloy is characterized by its low density and light weight, significantly reducing the weight of the entire wire rope splicing device compared to traditional steel, facilitating installation and transportation. At the same time, aluminum alloy possesses excellent mechanical properties; its strength and hardness meet the requirements of the wire rope splicing parts under complex working conditions, and it also has good corrosion resistance and oxidation resistance, extending the service life of the snap-fit ​​structure 1.

[0039] The specific working principle is as follows: When two steel wire ropes need to be spliced, the two steel wire rope bodies 102 are first inserted into the grooves 105 of the two first slot plates 101 respectively. By tightening the positioning screws 104, the steel wire ropes are fixed in the grooves 105, achieving a reliable connection between the steel wire ropes and the first slot plates 101. At this time, the first slot plates 101 with steel wire ropes are connected through the second fixed post 201, the movable connecting post 202, and the third fixed post 203. During the connection process, the slot posts 205 on both sides of the connecting sleeve 204 are subjected to external pressure. The compression spring 208 causes the locking plate 207 to move inward towards the connecting sleeve 204, and the slot posts 205 gradually retract into the connecting sleeve 204. Once the two snap-fit ​​structures 1 are aligned, the snap-fit ​​post 205 extends under the elastic force of the spring 208, and the snap-fit ​​plate 207 locks the mating part, thus achieving a firm connection between the two snap-fit ​​structures 1. During the use of the wire rope, even under complex working conditions such as vibration and stress concentration, the positioning screw 104 always firmly fixes the wire rope in the groove 105 of the first snap-fit ​​plate 101, preventing the wire rope from loosening. At the same time, the spring 208 in the snap-fit ​​structure 1 and the snap-fit ​​plate 207 cooperate with each other to effectively buffer external impacts, so that the load is evenly distributed at the splicing part, avoiding loosening of the connecting parts. Furthermore, the aluminum alloy snap-fit ​​structure 1 and the stainless steel compression spring 208 can adapt to harsh working environments, prevent the structure from being damaged by corrosion, ensure the reliability and safety of the overall structure, and effectively extend the fatigue life of the wire rope connection part.

[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
