[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0026] Please refer to Figures 1-7, an embodiment provided by the present utility model: a tensile steel wire rope, including a steel wire rope main body 1, a rope core 6 and steel wire strands 7 are arranged inside the steel wire rope main body 1. The rope core 6 is a metal strand core to improve the tensile capacity of the steel wire rope. There are multiple steel wire strands 7, and the multiple steel wire strands 7 are wound around the outer side of the rope core 6. A winding cloth tape 8 is wound around the outer side of the steel wire strands 7, and a silica gel sleeve 9 is arranged on the outer side of the winding cloth tape 8. The silica gel sleeve 9 is made of self-seeping oil silica gel material to facilitate the seepage of lubricating oil. A rubber sleeve 13 is arranged on the outer side of the rope core 6. Multiple oil storage cavities are arranged inside the rubber sleeve 13, and the multiple oil storage cavities are arranged in a circular pattern. An oil storage cotton 1301 is arranged inside the oil storage cavity. Lubricating oil is absorbed inside the oil storage cotton 1301, and the lubricating oil is silicone oil. Multiple lubricating holes 1302 are arranged along the outer side of the oil storage cavity inside the rubber sleeve 13.

[0027] During use, during the dynamic use of the steel wire rope, under the action of shaking, the steel wire strands 7 will press the rubber sleeve 13 on the outer side of the rope core 6, causing the oil storage cotton 1301 to be pressed and thus squeezing out the lubricating oil, which is discharged outward through the lubricating holes 1302. Through the flow and penetration of the oil liquid, it can flow to the surface of the silica gel sleeve 9, automatically lubricating the surface of the steel wire rope main body 1, thereby realizing the automatic lubrication and wear reduction of the steel wire rope during use, reducing the friction and wear of the steel wire rope during use, and improving the tensile performance and service life of the steel wire rope.

[0028] Furthermore, a wear-resistant sleeve 10 is arranged on the outer side of the steel wire strands 7 to improve the protection of the steel wire strands. A rubber column one 11 is arranged on the outer side between adjacent two steel wire strands 7, and a rubber column two 12 is arranged on the inner side between adjacent two steel wire strands 7. By arranging the rubber column two 12 and the rubber column one 11, the gap between adjacent two steel wire strands 7 can be filled, increasing the tightness inside the steel wire rope, and through the elastic buffering effect of the rubber column, it is beneficial to buffer the vibration of the steel wire strands.

[0029] Furthermore, a connecting block one 2 is fixedly installed at one end of the steel wire rope main body 1, a connecting column 3 is fixedly installed on one side of the connecting block one 2, a connecting block two 4 is fixedly installed at the other end of the steel wire rope main body 1, and a plug 5 is installed on one side of the connecting block two 4. By inserting the plug 5 into the inside of the connecting column 3, the convenient connection of two steel wire ropes is facilitated, increasing the practicality.

[0030] Furthermore, a round hole 301 is arranged on one side inside the connecting column 3, three insertion arc grooves 302 are arranged on the outer side of the round hole 301, the round hole 301 and the insertion arc grooves 302 are communicated, the three insertion arc grooves 302 are arranged in a circular pattern, a limiting arc groove 303 is arranged along one side of the insertion arc grooves 302 at one end of the outer side of the round hole 301, and the insertion arc grooves 302 and the round hole 301 are both communicated with the limiting arc groove 303.

[0031] Further, on the other side inside the connecting column 3, there is a spring chamber 304. The spring chamber 304 communicates with the round hole 301. Inside the spring chamber 304, there is a compression spring 15. The compression spring 15 is made of high-strength steel. On one side of the compression spring 15, there is a movable plate 16 fixedly installed. On one side of the movable plate 16, there are three convex arc plates 17 fixedly installed. The three convex arc plates 17 are arranged in a ring. The convex arc plates 17 correspond to the positions of the insertion arc grooves 302, and the convex arc plates 17 extend into the insertion arc grooves 302. The side projection size of the convex arc plates 17 matches the side projection sizes of the insertion arc grooves 302 and the limiting arc grooves 303. When the plug 5 and the connecting column 3 are plugged in, the convex arc plates 17 can elastically press the limiting arc plate 503 stably, increasing the practicability.

[0032] Further, the plug 5 includes a mounting plate 501, a plug post 502, and a limiting arc plate 503. The mounting plate 501 is fixedly connected to the second connecting block 4. The plug post 502 is fixedly installed on one side of the mounting plate 501. There are three limiting arc plates 503, and the three limiting arc plates 503 are arranged in a ring on the outside of the plug post 502. The diameter of the plug post 502 matches the inner diameter size of the round hole 301.

[0033] Further, there is a limiting hole 5031 inside the limiting arc plate 503, and a limiting post 14 inside the limiting arc groove 303. The limiting post 14 is fixedly connected to the connecting column 3. Then, during the plugging process of the plug 5 and the connecting column 3, after the limiting arc plate 503 rotates into the limiting arc groove 303, by moving the plug 5 outwards, the limiting post 14 is inserted into the limiting hole 5031 of the limiting arc plate 503, which can ensure the stability of the connection between the plug 5 and the connecting column 3.

[0034] Working principle: When in use, during the dynamic use of the wire rope, under the action of shaking, the wire strand rope 7 will press the rubber sleeve 13 outside the rope core 6, causing the oil storage cotton 1301 to be compressed and thus extruding lubricating oil, which is discharged outward through the lubricating holes 1302. Through the flow and penetration of the oil fluid, it can flow to the surface of the silica gel sleeve 9 to automatically lubricate the surface of the wire rope main body 1, enabling the wire rope to be automatically lubricated during use. At the same time, when the length of the wire rope is insufficient during use and two wire ropes need to be connected, hold the plug 5 of one wire rope, align the plug post 502 and the limiting arc plate 503 of the plug 5 with the round hole 301 and the insertion arc groove 302 on the connecting post 3 of the other wire rope respectively, then insert the plug 5 into the connecting post 3. Then the end of the plug post 502 will contact the movable plate 16. As the plug 5 is continuously pushed in, the plug post 502 will push the movable plate 16 to move, and the compression spring 15 is compressed. The convex arc plate 17 disengages from the inside of the insertion arc groove 302. Then rotate the plug 5 to move one end of the limiting hole 5031 of the limiting arc plate 503 into the limiting arc groove 303. Then release the plug 5. Through the elastic tension of the compression spring 15, the movable plate 16 drives the convex arc plate 17 to push the plug post 502 and the limiting arc plate 503 to move. Then the limiting post 14 in the limiting arc groove 303 is inserted into the limiting hole 5031 of the limiting arc plate 503 to achieve stable limitation of the limiting arc plate 503, and the connecting post 3 and the plug 5 are stably connected, facilitating the convenient connection of two wire ropes.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
