Technical Field

[0001] The utility model relates to the technical field of slope reinforcement, in particular to a road slope anchoring device. Background Technique

[0002] Slope reinforcement refers to the measures to improve the stability of open-pit mine slopes. It improves the slope stability by setting slope angle retaining walls under the slope angle of the slope fracture zone, setting anti-slide piles in local fracture zones or on slopes, and grouting into rock strata with open joints and fissures. These measures are not only beneficial to safety but also can increase the slope angle and reduce the stripping work volume.

[0026] The positioning assembly 7 includes a connecting frame 72 fixed on the top of the edge of the hole 8, a limiting assembly 73 and a stabilizing assembly 74 are arranged on the outer wall of the connecting frame 72, the limiting assembly 73 is located at both ends of the connecting frame 72, the stabilizing assembly 74 is arranged on both sides of the connecting frame 72, and the structure of the stabilizing assembly 74 is the same as that of the limiting assembly 73;

[0027] The limit component 73 includes an adjustment screw rod 732 threadedly connected to the connecting frame 72. One end of the adjustment screw rod 732 is provided with a limit support block 731. The limit support block 731 is in an arc structure. The inner side of the limit support block 731 is attached to the outer wall of the anchor rod 4. The outer wall of the limit support block 731 and the adjustment screw rod 732 are rotationally connected through a rotating shaft. The limit support block 731 of the limit component 73 with this structure can play a role in positioning, limiting, and lifting the anchor rod 4. By rotating the adjustment screw rod 732, the limit support block 731 can be pushed to move linearly. The limit support block 731 is located inside the connecting frame 72, and a measurement component 71 is arranged on the top side of the connecting frame 72. The measurement component 71 further includes a box body 711 fixed to the top side of the connecting frame 72. An opening is provided at one end of the box body 711.
