Description

Technical Field

[0001] This utility model relates to the field of dangerous rock treatment technology, specifically a dangerous rock reinforcement and protection device. Background Technology

[0002] As a common geological hazard, unstable rock formations are closely related to various factors such as geological structure, strata lithology, rock mass structure, and groundwater activity. In mountainous areas, canyons, and engineering construction zones, the presence of unstable rock formations seriously threatens the lives of surrounding residents, the stable operation of infrastructure, and the balance of the ecological environment.

[0003] Currently, the management of unstable rock masses involves either removal or reinforcement. However, for large-scale unstable rock masses with limited safety space below and close proximity to the protected object, removal is difficult and may trigger secondary disasters. Therefore, reinforcement and protective measures are more effective for the management of unstable rock masses. Utility Model Content

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] like Figure 1-5 As shown, a rock reinforcement and protection device includes multiple sets of fixed anchor rods 1. The anchor rods are hollow inside, and a main shaft 2 is rotatably connected inside the anchor rods. The upper side of the main shaft 2 extends from the upper side of the anchor rods. Gears 3 are provided on both the upper and lower sides of the main shaft 2. Gear racks 4 are meshed on both the front and rear sides of the gears 3. Openings corresponding to the racks 4 are opened on both sides of the fixed anchor rods 1. A connecting block 5 with a through opening is connected to one side of the rack 4.

[0021] The fixed anchor rod 1 has a bearing block 6 inside, and a guide groove 7 is provided on the upper side of the bearing block 6. The rack 4 is slidably connected to the guide groove 7. A hexagonal block 8 is fixed on the upper side of the main shaft 2. The hexagonal block is designed as a wrench clamping point to facilitate the rotation of the main shaft 2 with a wrench. A bearing plate 9 is installed on the upper side of the hexagonal block, and the upper side of the main shaft 2 is provided with external threads.

[0022] A rope 10 is connected to the upper side of the main shaft 2. A connecting hook 11 is provided at one end of the rope 10, and a reinforcing net 12 is connected to the connecting hook 11. A connecting component is provided on one side of the connecting block 5. The reinforcing net 12 is used to cover the dangerous rock to further prevent the dangerous rock and soil from falling and causing danger.

[0023] The connecting assembly includes a protrusion 13 on one side of the connecting block 5, with a threaded hole on the protrusion 13. A connecting shell 14 is inserted into the protrusion 13. A vertical plate 15 is provided on one side of the connecting shell 14, and a connecting bolt corresponding to the threaded hole is inserted into one side of the connecting shell 14. The connecting bolt is screwed into the threaded hole from the side of the connecting shell 14 to achieve a fixed connection between the connecting shell 14 and the connecting block 5.

[0024] Operators can drill holes near the rock mass and insert reinforcing anchor rods into the holes. Then, operators can use tools to rotate hexagonal block 8, thereby driving spindle 2 and gear 3 to rotate.

[0025] Gear 3, in conjunction with rack 4, drives connecting block 5 to extend, and through protrusion 13 and connecting shell 14, drives vertical plate 15 to move, so that vertical plate 15 is tightly attached to the inner wall of the opening and the reinforcing anchor is in the center of the opening. Then, concrete is poured into the opening to increase the connection strength between the reinforcing anchor and the opening. After the reinforcing anchor is fixed, rope 10 is inserted into the cross notch on the upper side of main shaft 2. Then, locking nut 19 is threaded to the upper side of main shaft 2 and fixed with bearing plate 9. The connecting hook 11 is used in conjunction with reinforcing net 12 to reinforce the rock mass.

[0026] like Figure 5 As shown, since there may be a large area of ​​soft soil around the rock mass, concrete pouring cannot achieve the reinforcement effect. At this time, the operator can remove and replace the vertical plate 15, and use the connecting shell 14 to connect the insert 16 and the connecting block 5. After inserting the reinforcing anchor into the soil, the main shaft 2 is rotated again using a tool. Through the cooperation of the gear 3, rack 4, and connecting block 5, the insert 16 extends into the soil, increasing the contact area between the reinforcing anchor and the soil. At the same time, inclined blocks 17 are set on both the upper and lower sides of the insert 16 to further increase the contact area between the insert 16 and the soil, thereby increasing the fixing effect between the reinforcing anchor and the soil.

[0027] A tapered head 18 is provided on the lower side of the fixed anchor rod 1 to facilitate the insertion of the anchor rod into the soil.

[0028] A cross notch is provided on the upper side of the main shaft 2, and a locking nut 19 is threaded onto the upper side of the main shaft 2 for connecting the rope 10 to the reinforcing anchor rod.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
