[0051] The top end of the second threaded rod 15 is connected to a second disc 16, and the fixing block 17 is disposed on the second disc 16. The first disc 13 and the second disc 16 are provided to facilitate the rotation of the first threaded rod 12 and the second threaded rod 15, and to provide enough space for installing the corresponding hook 14 and fixing block 17 structures.

[0052] In this embodiment, when it is necessary to support the slope of the open-pit mine, first, the two second anchor rods 102 are fixedly inserted at specific positions in the top area of ​​the slope, and then the two first anchor rods 101 are fixedly inserted at specific positions at the bottom end of the slope, and then the free end of the wire rope net 11 is pulled to the bottom end area of ​​the slope, and then the hook 14 is used to hook the specific position on the wire rope net, so that the deployment operation of the wire rope net 11 can be completed. When the rock structure of the slope changes, the connection position of the hook 14 and the wire rope net 11 can be changed. When the wire rope net 11 needs to be stored, the lock of the hook 14 on the wire rope net 11 is unlocked, and then the winding roller 20 is rotated, and the wire rope net 11 will be rewound on the winding roller 20 in an orderly manner, and then the first anchor rod 101 and the second anchor rod 102 can be pulled out. Among them, the setting of the first rocker 22 can facilitate the rotation of the transmission rod 19 to unfold or store the wire rope net 11.

[0053] Preferably, a protective tube 18 located outside the winding roller 20 is connected between the two fixing blocks 17 , and a strip-shaped opening 21 is provided on the protective tube 18 for allowing the steel wire rope net 11 to pass through.

[0054] In this embodiment, the protection tube 18 is used to protect the rolled steel wire rope net 11, and the strip opening 21 allows the steel wire rope net 11 to be unfolded or stored in an orderly manner.

[0055] Preferably, a limiting mechanism is also provided on any one of the two fixing blocks 17;

[0056] The limiting mechanism includes a plurality of limiting blocks 901 connected to one end of the rotating rod 19 and arranged in an upward circular manner;

[0057] The limiting mechanism also includes a mounting cover 902 fixedly connected to the fixed block 17, the mounting cover 902 having a notch 1001 extending therethrough, a sliding plate 903 suspended on the inner wall of the side end of the mounting cover 902, the end of the sliding plate 903 being connected to a toggle plate 1002 passing through the notch 1001, a third spring 1003 for supporting the sliding plate 903 being arranged on the inner wall of the bottom end of the mounting cover 902, a triangular block 904 being arranged on the top end of the sliding plate 903, the triangular block 904 having a limiting surface 905 and an inclined surface 906 which can cooperate with the limiting block 901.

[0058] In this embodiment, Figure 1 and Figure 2Taking the right view of as an example, the wire rope net 11 can be pulled out by rotating the rotating rod 19 clockwise. Without external force, when the rotating rod 19 rotates clockwise, the limit block 901 will contact the limit surface 905, so that the triangular block 904 will block the rotation of the rotating rod 19. At this time, external force is applied to move the toggle plate 1002, so that it drives the sliding plate 903 and the triangular block 904 to move downward to release the restriction on the limit block 901. In this way, the wire rope net 11 can be unfolded; when it needs to be stored When the wire rope net 11 is wound, the rotating rod 19 is rotated counterclockwise. At this time, the limit block 901 will contact the inclined surface 906. Under the action of the rotational kinetic energy, the limit block 901 will push the triangular block 904 and the sliding plate 903 to continuously press down the third spring 1003. If an unexpected reaction force (reverse rotation) occurs during the winding process, the limit surface 905 will promptly block the movement of the limit block 901 in this direction. This can effectively prevent the wire rope net 11 from becoming loose or flowing back during storage.

[0059] Preferably, the protective tube 18 is also provided with a cleaning mechanism;

[0060] The cleaning mechanism includes a connecting frame installed on the protective tube 18, on which two cleaning plates 501 are installed opposite to each other. The two cleaning plates 501 are respectively located on the upper and lower sides of the wire rope net 11, and a plurality of bristles 502 are arranged at the working ends of the cleaning plates 501.

[0061] In this embodiment, when the wire rope net 11 is unfolded or stored, the bristles 502 can clean the impurities on the upper and lower end surfaces of the wire rope net 11 to avoid excessive impurities remaining thereon.

[0062] Preferably, the end surface of the other end of the rotating rod 19 is provided with a plurality of cleaning protrusions 702 arranged in an annular manner;

[0063] The cleaning plate 501 can be slidably arranged on the connecting frame;

[0064] The connecting frame includes two groups of connecting plate groups corresponding to the two cleaning plates 501 respectively, each connecting plate group includes two connecting plates 601 respectively located at the two ends of the cleaning plate 501, both ends of the cleaning plate 501 are connected with guide rods 602 passing through the connecting plates 601, the guide rod 602 located at one end of the cleaning plate 501 is connected with an L-shaped plate 603 located on the outside of the connecting plate 601, the L-shaped plate 603 is connected with a pushing plate 701 that can cooperate with the cleaning protrusion 702, and the guide rod 602 located at the other end of the cleaning plate 501 is connected with an anti-slip head 605 located on the outside of the connecting plate 601;

[0065] It also includes a second spring 604 sleeved on the guide rod 602, and two ends of the second spring 604 are respectively abutted against the cleaning plate 501 and the connecting plate 601.

[0066] In this embodiment, when the wire rope net 11 is unfolded or stored, the rotating rod 19 will rotate forward or reverse. Figure 4 and Fig.10 As shown, the cleaning protrusion 702 will continuously push the plate 701 to the left, and then under the reset action of the second spring 604, the cleaning plate 501 will move regularly to the left and right, so that the upper and lower end surfaces of the wire rope net 11 can be cleaned over a large area.

[0067] In order to realize the pushing effect of the cleaning protrusion 702 on the pushing plate 701, the cleaning protrusion 702 can be in a hemispherical shape or a truncated cone shape.

[0068] Preferably, a gear 201 is sleeved on the other end of the rotating rod 19;

[0069] The fixing block 17 is also provided with an adjustment mechanism;

As the third threaded rod 804 moves downward, the rack 205 drives the gear 201 to rotate, thereby driving the rotating rod 19 and the winding roller 20 to rotate slightly in the opposite direction to tighten the wire rope net 11.

When the third threaded rod 804 moves downward to gradually tighten the wire rope net 11, the first spring 303 is gradually compressed, so that the distance between the indicator plate 203 and the mounting plate 204 gradually decreases, so that the operator can know the magnitude of the tensioning force.
