Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wire rope, specifically relating to a wire rope with protective function. Background Technology
[0002] Steel wire ropes are widely used in lifting, traction, construction, mining and other fields. However, due to their long-term exposure to complex environments, they are easily damaged by wear, corrosion and impact, which leads to a reduction in service life and even causes safety accidents.
[0003] While wrapping steel wire ropes with rubber, nylon, or metal braided layers can provide some mechanical protection, the sheaths are usually fixed and non-extensible, affecting the flexibility and dynamic performance of the steel wire rope. Ordinary rubber or plastic sheaths are easily damaged under high-intensity friction or impact, and cannot protect the steel wire rope for a long time. They are also prone to aging, cracking, or loss of protective effect in extreme temperature and corrosive environments. Therefore, a steel wire rope with protective functions needs to be designed to overcome the above-mentioned technical defects. Utility Model Content

The steel wire rope with protective function aims to solve the technical problem that although the steel wire rope wrapped with rubber, nylon or metal braided layer can provide a certain mechanical protection, the sheath is usually fixed and cannot be stretched, which affects the flexibility and dynamic performance of the steel wire rope.

[0008] Preferably, the protective component includes an arc-shaped fixing block, which is fixed to the bottom of the wire feeding box. A telescopic protective tube is sleeved on the outside of the arc-shaped fixing block. The telescopic protective tube consists of a first telescopic protective layer, a second telescopic protective layer, a third telescopic protective layer, and a circular protective steel ring.

[0023] This specific embodiment is a steel wire rope with protective function, and its structural diagram is shown below. Figures 1-5 As shown, the protective wire rope includes a wire feeding box 1, a drive motor 2 is bolted to one end of the wire feeding box 1, a feeding roller is provided at the output end of the drive motor 2, a wire is sleeved on the outside of the feeding roller, and a protective component for wire protection is provided at the bottom of the wire feeding box 1.
[0024] The protective component includes an arc-shaped fixing block 4, which is fixed to the bottom of the wire feeding box 1. A telescopic protective tube 3 is sleeved on the outside of the arc-shaped fixing block 4. The telescopic protective tube 3 is composed of a first telescopic protective layer 31, a second telescopic protective layer 32, a third telescopic protective layer 33, and a circular protective steel ring 34. The second telescopic protective layer 32 is provided on the outside of the first telescopic protective layer 31, and the third telescopic protective layer 33 is provided on the inside of the first telescopic protective layer 31. Multiple circular protective steel rings 34 are evenly distributed inside the first telescopic protective layer 31. A binding mechanism is provided at the bottom of the telescopic protective tube 3 for connecting the bottom of the telescopic protective tube 3 to the wire. The circular protective steel rings 34 can withstand external pressure, so that the telescopic protective tube 3 maintains a circular cross-section and prevents the telescopic protective tube 3 from deforming.
[0025] The first telescopic protective layer 31 is made of silicone. Silicone has excellent elasticity and cushioning properties, can absorb severe impact energy, and can convert impact energy into heat energy, thereby improving the protective performance of this device.
[0026] The second stretchable protective layer 32 is made of polytetrafluoroethylene (PTFE). PTFE can resist almost all strong acids, strong alkalis, organic solvents and oxidants. It does not degrade after long-term outdoor exposure, and rainwater can wash away surface pollutants, thus improving its protective performance.
[0027] The third telescopic protective layer 33 is made of Kevlar, a high-performance synthetic fiber known for its ultra-high strength, lightweight and impact resistance. Kevlar fibers disperse energy through fiber delamination deformation and breakage when subjected to impact, thanks to the highly oriented molecular chains and hydrogen bond network. This effectively protects against the impact that occurs when the steel wire breaks.
[0028] The restraint mechanism includes an arc-shaped mounting block 5. One end of the arc-shaped mounting block 5 is rotatably connected to a transverse rotating column 6 via a bearing. One end of the transverse rotating column 6 is fixed with a transverse threaded rod 8. One end of the transverse threaded rod 8 is fixed with a circular rotating knob 9. A longitudinal moving plate 10 is threadedly connected to the outer side of the transverse threaded rod 8. A longitudinal fixing block 7 is rotatably connected to the outer side of the transverse rotating column 6 via a bearing. A circular restraint strap 11 is sleeved on the outer side of the telescopic protective tube 3. The two ends of the circular restraint strap 11 are respectively fixed to the two ends of the longitudinal moving plate 10.
[0029] The interior of the longitudinal fixing block 7 is provided with a rectangular through groove. The circular binding strap 11 is located inside the rectangular through groove and is slidably connected to the longitudinal fixing block 7 through the rectangular through groove. The rectangular through groove allows the circular binding strap 11 to slide inside the longitudinal fixing block 7. The movement of the longitudinal moving plate 10 allows the circular binding strap 11 to bind the outside of the telescopic protective tube 3 so that the telescopic protective tube 3 can be installed on the outside of the steel wire.
[0030] Here, by rotating the circular rotary knob 9, the rotation of the circular rotary knob 9 causes the transverse threaded rod 8 to rotate, the rotation of the transverse threaded rod 8 causes the transverse rotating column 6 to rotate at one end of the arc-shaped mounting block 5, the rotation of the transverse threaded rod 8 causes the longitudinal moving plate 10 to move, and thus the circular restraint strap 11 can move inside the longitudinal fixing block 7, and thus the circular restraint strap 11 can drive the telescopic protective tube 3 to move towards the outside of the steel wire, so that the telescopic protective tube 3 can be fixed to the outside of the steel wire.
[0031] Working principle: When using the protective wire rope of this technical solution, by rotating the circular rotary knob 9, the rotation of the circular rotary knob 9 causes the transverse threaded rod 8 to rotate, the rotation of the transverse threaded rod 8 causes the transverse rotating column 6 to rotate at one end of the arc-shaped mounting block 5, the rotation of the transverse threaded rod 8 causes the longitudinal moving plate 10 to move, and then the circular binding strap 11 can move inside the longitudinal fixing block 7, and then the circular binding strap 11 can drive the telescopic protective tube 3 to move towards the outside of the wire, so that the telescopic protective tube 3 can be fixed to the outside of the wire.
[0032] By employing a first telescopic protective layer 31, a second telescopic protective layer 32, a third telescopic protective layer 33, and a circular protective steel ring 34, the telescopic protective tube 3 can extend or retract synchronously with the raising and lowering of the wire rope. This avoids the rigid constraints of traditional fixed sheaths or the jamming problems of segmented protective covers, prevents the intrusion of external dust, moisture, and corrosive media, reduces the corrosion and wear of the wire rope, and has good impact resistance, cut resistance, and wear resistance. The restraint mechanism can adapt to changes in the diameter of the wire rope, ensuring that there is no relative slippage between the telescopic protective tube 3 and the wire rope.
[0033] All technical features in this embodiment can be freely combined according to actual needs.
[0034] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
