[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. A detachable wear-resistant mechanism is installed. Through the cooperation of the partition frame, T-shaped reinforcing cylinder, reset slip ring, internal threaded sleeve, arc-shaped pad, and reset spring, the wear-resistant buckle can be quickly and easily spliced ​​into sections on the outside of the wear-resistant inner layer, thus forming a detachable wear-resistant component in the wear-resistant inner layer. After wear occurs, the worn wear-resistant buckle can be quickly removed, allowing for individual replacement without the need for overall disassembly, improving maintenance convenience, ensuring the wear resistance of the cable, and increasing its service life. The reset spring pulls the reset slip ring and internal threaded sleeve to retract, facilitating storage. The combination of the arc-shaped frame and the anti-deviation support rod supports and limits the wear-resistant hook and loop, making it easy to rotate the inner threaded sleeve and connect it with the arc-shaped pad. This improves the stability of the wear-resistant hook and loop when installed on the outside of the cable and ensures the structural strength and tensile strength of the wear-resistant hook and loop after installation. In addition, the combination of filler blocks, C-shaped slots and mating blocks makes it easy to splice two wear-resistant hooks together. Then, the combination of sealing strips and positioning pins further improves the stability of the splicing of the two wear-resistant hooks, and can also seal the gaps at the splicing point, thus improving the sealing performance.

[0015] 2. A convenient docking and anti-loosening mechanism is set up. The internal threaded sleeve is threadedly connected to the connecting cylinder, which is fixed between the two cables. The anti-deviation top rod is embedded in the round hole on the separator frame to effectively prevent the connecting cylinder from rotating. Then, the two arc-shaped sleeves are spliced ​​together with bolts. The inner threaded sleeve is limited by the cooperation of the insert, insert rod and anti-slip pad to prevent the inner threaded sleeve from reversing and to prevent loosening. The conductor connection is elastically clamped by a contraction clamping spring driving the movable ring, rotating frame and arc-shaped clamping plate. Combined with the guide and limit of the telescopic slide and positioning support, the stability of the cable connection and the vibration and loosening resistance are improved.

[0016] In summary, the combination of a detachable wear-resistant mechanism and a convenient docking and anti-loosening mechanism enables segmented assembly of the outer sheath. This ensures the cable's wear resistance while allowing for rapid disassembly and replacement of severely worn sections, reducing maintenance costs. It also ensures the long-term stability of cable connections, preventing loosening and detachment. Furthermore, the internal fire-resistant structure comprehensively enhances the durability, safety, and maintenance efficiency of mining cables, enabling long-term use in harsh environments.

The inner wall of the T-shaped reinforcing cylinder 602 slides against the outside of the reset slip ring 604. The width of the T-shaped reinforcing cylinder 602 is equal to the width of the dividing frame 601.

A wear-resistant buckle 609 is sleeved on the outer side of the arc-shaped frame 607, and arc-shaped pads 610 are snapped into both ends of the wear-resistant buckle 609. In order to facilitate the fixing of the wear-resistant buckle 609, grooves are equally spaced on the inner wall of the wear-resistant buckle 609, and one end of the anti-deviation support rod 608 is embedded in the groove. The two arc-shaped pads 610 are tightly fitted at their adjacent ends, and the outer side of the arc-shaped pad 610 is connected to the inner wall of the internal threaded sleeve 605 by threads. Both ends of the two wear-resistant hook-and-loop fasteners 609 are engaged with a limiting frame 611. A filler block 612 is engaged inside the limiting frame 611. C-shaped slots 613 are equidistantly opened at one end of the two opposite filler blocks 612, and mating blocks 614 are equidistantly engaged at one end of the filler blocks 612. In order to improve the tightness of the engagement of the two wear-resistant hook-and-loop fasteners 609, one end of the limiting frame 611 is attached to one end of the arc frame 607. The C-shaped slots 613 and mating blocks 614 on the two opposite filler blocks 612 are equidistantly staggered, and the mating block 614 on one filler block 612 is embedded inside the C-shaped slot 613. The corresponding limiting frame 611 between the two wear-resistant buckles 609 is filled with a sealing strip 615, and the sealing strip 615 is connected with positioning pins 616 at equal intervals by threads. In order to fix the sealing strip 615, the mating block 614 has a positioning hole, and one end of the positioning pin 616 passes through the sealing strip 615 and is connected to the inner wall of the positioning hole by threads. The outer side of the sealing strip 615 is tightly fitted with the inner wall of the limiting frame 611. A convenient docking and anti-loosening mechanism 7 is provided between the inner shielding layers 1. The two convenient docking and anti-loosening mechanisms 7 include a connecting cylinder 701. A connecting cylinder 701 is threadedly connected to the inner side of the corresponding inner threaded sleeve 605 between the two inner shielding layers 1. A bonding plate 702 is symmetrically snapped into the inner wall of the connecting cylinder 701, and an anti-deviation rod 703 is equidistantly snapped into one end of the bonding plate 702. In order to prevent the connecting cylinder 701 from rotating, a circular hole is equidistantly opened at one end of the partition frame 601, and one end of the anti-deviation rod 703 is embedded in the circular hole. The outer side of the connecting cylinder 701 is threadedly connected to the inner wall of the inner threaded sleeve 605. A retaining ring 704 is symmetrically sleeved on the outside of the connecting cylinder 701, and an insert 705 is symmetrically and equidistantly snapped between the two retaining rings 704 on the outside of the connecting cylinder 701. An insert rod 706 is movably connected inside the insert 705, and an arc-shaped sleeve 707 is snapped at the other end of the insert rod 706. Anti-slip pads 708 are symmetrically snapped on the inner wall of the arc-shaped sleeve 707. In order to improve the sealing performance of the connecting cylinder 701, the adjacent ends of the two arc-shaped sleeves 707 are connected by bolts. The outer diameter of the retaining ring 704 is equal to the outer diameter of the internal threaded sleeve 605, and anti-slip texture is opened on the outer side of the internal threaded sleeve 605 corresponding to the inner side of the anti-slip pad 708. Two bonding plates 702 are equidistantly engaged with limiting slide rods 709. The outer side of the limiting slide rods 709 is symmetrically and movably sleeved with movable rings 710, and the outer side of the limiting slide rods 709 is engaged with a retraction clamping spring 711 between the two movable rings 710. Two movable rings 710 are equidistantly rotatably connected to a rotating frame 712 at one end. The other end of the rotating frame 712 is rotatably connected to an arc-shaped clamp 713. One end of the arc-shaped clamp 713 is engaged with a telescopic slide 714. The inner wall of the connecting cylinder 701 is engaged with a positioning support 715 corresponding to the inside of the telescopic slide 714. In order to fix the connection of the conductor 3, the outer side of the movable ring 710 is in contact with the inner wall of the connecting cylinder 701. One end of the positioning support 715 is embedded in the inside of the telescopic slide 714, and both ends of the positioning support 715 are slidably in contact with the inner wall of the telescopic slide 714.

[0023] The working principle and usage process of this invention are as follows: First, the conductor 3 and the reinforcing ribs are wrapped and wrapped by the winding tape 2, which forces the reinforcing ribs to support the conductor 3 and prevent the conductor 3 from being misaligned. Then, the fire resistance of the cable is increased by the combination of the flame-retardant and fire-resistant layer 4 and the wear-resistant inner layer 5. Next, by cooperating with the partition frame 601 on the outer side of the wear-resistant inner layer 5 and the T-shaped reinforcing cylinder 602, it is convenient to install the reset slip ring 604 and the internal thread sleeve 605 equidistantly on the outer side of the wear-resistant inner layer 5. Then, the two wear-resistant buckles 609 are aligned and fitted onto the arc frame 607, and the limiting clip frame 611 on the wear-resistant buckle 609 is embedded between the two arc frames 607. At the same time, the filling blocks 612 at both ends of the two wear-resistant buckles 609 correspond to each other, so that the mating plug 614 can be embedded into the C-shaped slot 613, which improves the tightness of the mating between the two wear-resistant buckles 609 and the two arc pads 610. Subsequently, the positioning pin 616 is rotated to pass through the sealing strip 615 and embed into the positioning hole, thereby filling the sealing strip 615 onto the filling block 612 inside the limit frame 611, sealing the joint of the two wear-resistant buckles 609, improving the sealing performance and preventing gaps. In addition, after the two wear-resistant hooks 609 are aligned and fitted onto the outside of the arc frame 607, the positioning rod 603 on the arc frame 607 is embedded into the groove on the inner wall of the wear-resistant hook 609 to limit the wear-resistant hook 609. This allows the inner threaded sleeve 605 to be rotated and pulled out from between the separator frame 601 and the T-shaped reinforcing cylinder 602, making it easier for the inner threaded sleeve 605 to be threadedly connected to the arc pad 610. This allows the two wear-resistant hooks 609 to be spliced ​​and fixed on the outside of the wear-resistant inner layer 5, which is convenient for protecting the wear-resistant inner layer 5. When the wear-resistant latch 609 of the mining cable is damaged during long-term use and pulling, the inner threaded sleeve 605 is rotated to release the connection with the arc-shaped pad 610. Then, through the contraction characteristic of the return spring 606, the return slip ring 604 and the inner threaded sleeve 605 are pulled to slide and retract between the separator frame 601 and the T-shaped reinforcing cylinder 602, releasing the restriction on the wear-resistant latch 609 and the arc-shaped pad 610. Then, the positioning pin 616 is rotated to remove the sealing strip 615, further releasing the restriction on the two wear-resistant latches 609, making it easy to remove the wear-resistant latches 609 for replacement and re-splicing. This improves maintenance efficiency, ensures the wear resistance of the mining cable, and increases its service life. Furthermore, through the cooperation of the separator frame 601 and the T-shaped reinforcing cylinder 602, the wear-resistant latches 609 are spliced ​​in sections on the outside of the cable, making it convenient to replace only the corresponding positions and improving convenience. Next, when connecting the two cables, the connecting cylinder 701 is placed between the two cables, and then the conductors 3 inside the two cables are connected together. Then, the connecting cylinder 701 is fixed by the engagement of the internal threaded sleeve 605. At the same time, the two anti-deviation top rods 703 on the inner wall of the connecting cylinder 701 are embedded in the round hole on the separator frame 601, which improves the stability of the connecting cylinder 701 between the two cables. Next, through the cooperation of the insert 705 and the insert rod 706, the two arc-shaped sleeves 707 are easily aligned and fitted onto the outside of the connecting cylinder 701. At the same time, the two arc-shaped sleeves 707 are fixedly connected by bolts, which improves the stability of the splicing of the two arc-shaped sleeves 707. When the two arc-shaped sleeves 707 are spliced ​​and fitted, the anti-slip pad 708 is tightly fitted with the anti-slip texture on the outside of the internal thread sleeve 605, which limits the internal thread sleeve 605 and prevents the internal thread sleeve 605 from reversing, ensuring the stability of the connection between the internal thread sleeve 605 and the connecting cylinder 701 and preventing loosening and falling off. Finally, after the connecting cylinder 701 is fixed, the two movable rings 710 slide relative to each other along the limiting slide bar 709 by means of the shrinking clamping spring 711, and push the arc-shaped clamping plate 713 to move through the cooperation of the rotating frame 712, thereby clamping and fixing the connected conductor 3 and improving the stability of the connection. In addition, the arc-shaped clamping plate 713 is limited by the cooperation of the telescopic slide 714 and the positioning support 715, which improves the stability of the arc-shaped clamping plate 713 when sliding, improves the stability of clamping, and reduces shaking.

[0024] After completing the connection of conductor 3 and external clamping and fixing, the arc-shaped sleeve 707 is locked a second time by rotating the retaining ring 704 in conjunction with the axial limiting effect of the insertion rod 706, so that it forms a radial preload with the outer wall of the connecting cylinder 701, thereby further improving the vibration resistance of the overall structure. Meanwhile, when the cable is subjected to external impact or bending, the arc-shaped clamp 713 generates adaptive fine-tuning displacement under the linkage of the rotating frame 712, and with the guiding effect of the limit slide rod 709, it realizes dynamic buffer protection for the connection part of conductor 3, avoiding loosening or damage caused by stress concentration. Furthermore, the friction-enhancing structure between the anti-slip pad 708 and the internal threaded sleeve 605 forms a stable self-locking state during long-term use, thereby maintaining connection tightness and structural reliability under complex working conditions.

[0025] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
