[0014] This utility model provides a slope protection device for open-pit mines. By attaching and fixing a protective net and multiple protective plates to the slope, it can protect the slope, thereby reducing the risk of slope collapse. Even if the slope collapses, it can prevent falling rocks and soil from injuring workers at the bottom of the slope. A drive motor rotates the shaft and drum, which winds and stores the protective net. A positioning mechanism positions the device, and positioning plates and multiple first anchor rods fix one end of the protective net to the bottom of the slope. Multiple second anchor rods install multiple protective plates on each step of the slope, thus protecting each step of the slope. An extension opening allows the protective net to extend to the outside of the storage box. The protective netting is guided by guide rollers. Pull rings and multiple sliding rods move the pin block laterally, separating it from the pin groove and releasing the rotational lock on the shaft and drum. Spring return allows the pin block to engage in the pin groove, locking the shaft and drum in place. A dual-axis motor, two transmission rods, and multiple bevel gears drive two screws to rotate. These screws move the lifting plate and multiple spiral rods downwards. A servo motor, multiple double-groove synchronous pulleys, and multiple synchronous belts drive multiple spiral rods to rotate, causing them to screw into the ground and securely mount the base to the top of the slope. Multiple clearance openings allow for clearance between the spiral rods. The device is operated and controlled by a controller. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1-6 ,in, Figure 1 A schematic diagram of a preferred embodiment of the open-pit mine slope protection device provided by this utility model; Figure 2 for Figure 1 A top-view sectional view of the storage box; Figure 3 for Figure 1 An enlarged schematic diagram of part A shown in the image; Figure 4 for Figure 1 An enlarged schematic diagram of part B shown in the image; Figure 5 for Figure 1 An enlarged schematic diagram of section C shown in the image; Figure 6 for Figure 2 The enlarged schematic diagram of part D shown in the figure. The open-pit mine slope protection device includes: a base 1; a storage box 2 fixedly installed on the top of the base 1; a rotating shaft 3 rotatably installed on the inner wall of the storage box 2 and equipped with a drum 4; a drive motor 10 fixedly installed on one side of the inner wall of the storage box 2 and connected to the rotating shaft 3 via a coupling, the drive motor 10 being model HTYPG90S-8; a protective net 5 installed on the drum 4 for protecting the open-pit mine slope; and an installation and positioning mechanism installed on the inner wall of the base 1 for installing and positioning the protection device. The protective net 5 and multiple protective plates 8 attached and fixed to the slope can protect the slope, thereby reducing the risk of slope collapse. Even if the slope collapses, it can prevent falling rocks and soil from injuring workers at the bottom of the slope. The drive motor 10 drives the rotating shaft 3 and the drum 4 to rotate, and the rotation of the drum 4 can wind and store the protective net 5. The installation and positioning mechanism can install and position the device.

[0024] A positioning plate 6 is fixedly installed at one end of the protective net 5. Multiple first anchor rods 7 are provided on the positioning plate 6. Multiple protective plates 8 are provided on the protective net 5. Second anchor rods 9 are provided on each of the multiple protective plates 8. The positioning plate 6 and the multiple first anchor rods 7 can fix one end of the protective net 5 to the bottom of the slope. The multiple second anchor rods 9 can install the multiple protective plates 8 on each step of the slope, so that the protective net 5 can protect each step of the slope.

[0025] The storage box 2 has an extension opening 11 on one side. Two guide rollers 12 are rotatably installed on the inner wall of the extension opening 11. Both guide rollers 12 are slidably connected to the protective net 5. The protective net 5 can be extended to the outside of the storage box 2 through the extension opening 11, and the protective net 5 can be guided by the guide rollers 12.

[0026] The inner wall of the storage box 2 is provided with a locking mechanism, which includes: a sleeve plate 13 fixedly sleeved on the rotating shaft 3 and having multiple pin grooves 14; multiple sliding rods 15 slidably installed on the storage box 2; a pin block 16 fixedly installed on one end of the multiple sliding rods 15 and adapted to the pin grooves 14; multiple springs 17 respectively slidably sleeved on the multiple sliding rods 15; and a pull ring 18 fixedly installed on one end of the multiple sliding rods 15. The pull ring 18 and the multiple sliding rods 15 drive the pin block 16 to move laterally, so that the pin block 16 separates from the pin grooves 14, thereby releasing the rotational locking state of the rotating shaft 3 and the drum 4. The spring 17 rebounds and can make the pin block 16 engage in the pin grooves 14, thereby locking the rotating shaft 3 and the drum 4 in rotation.

[0027] The installation and positioning mechanism includes: two screws 19 rotatably mounted on the inner wall of the base 1; a lifting plate 20 threaded onto the two screws 19; a dual-axis motor 21 fixedly mounted on the top inner wall of the base 1, the model of the dual-axis motor 21 being STP-28D300X; two transmission rods 22 mounted at both ends of the output shaft of the dual-axis motor 21 via couplings; multiple bevel gears 23 respectively fixedly mounted on the two ends of the two transmission rods 22 that are far apart from each other and on the two screws 19 and meshing with each other; multiple spiral rods 24 rotatably mounted on the lifting plate 20; and a drive mechanism mounted on the lifting plate 20, which drives the two screws 19 to rotate via the dual-axis motor 21, the two transmission rods 22, and the multiple bevel gears 23. The rotation of the two screws 19 drives the lifting plate 20 and the multiple spiral rods 24 to move downwards. The multiple spiral rods 24 can be driven to rotate via a servo motor 25, multiple double-groove synchronous pulleys 26, and multiple synchronous belts, thereby causing the multiple rotating spiral rods 24 to screw into the ground.

[0028] The drive mechanism includes: a servo motor 25 fixedly mounted on the lifting plate 20, the servo motor 25 being of model ECMA-C20807RS; multiple double-groove synchronous pulleys 26 respectively fixedly sleeved on the output shaft of the servo motor 25 and on the multiple screw rods 24; and multiple synchronous belts sleeved on the multiple double-groove synchronous pulleys 26, which can drive the multiple screw rods 24 to rotate through the servo motor 25, the multiple double-groove synchronous pulleys 26, and the multiple synchronous belts.

[0029] The base 1 has multiple clearance openings 27 at its bottom, and the storage box 2 is equipped with a controller 28. Multiple spiral rods 24 can be cleared through the clearance openings 27, and the device can be operated and controlled through the controller 28.

[0030] The working principle of the open-pit mine slope protection device provided by this utility model is as follows:

[0031] Place base 1 on the top of the slope and start the dual-axis motor 21. The dual-axis motor 21 drives two screws 19 to rotate through two transmission rods 22 and multiple bevel gears 23. The rotation of the two screws 19 drives the lifting plate 20 and multiple spiral rods 24 to move downwards. Through the servo motor 25, multiple double-groove synchronous pulleys 26 and multiple synchronous belts, the multiple spiral rods 24 can be driven to rotate, thereby causing the multiple rotating spiral rods 24 to screw into the ground, thus firmly installing base 1 on the top of the slope. Pull the pull ring 18 to one side. Through the pull ring 18 and multiple sliding rods 15, the pin block 16 is driven to move laterally, causing the pin block 16 to separate from the pin groove 14, thereby releasing the rotational locking state of the rotating shaft 3 and the drum 4. The protective gear is then secured by the positioning plate 6. One end of the net 5 is pulled towards the bottom of the slope, and the positioning plate 6 is fixed to the bottom of the slope by multiple first anchor rods 7, thereby fixing one end of the protective net 5 to the bottom of the slope. Multiple second anchor rods 9 are used to install multiple protective plates 8 on each step of the slope, so that the protective net 5 can protect each step of the slope. After completion, the pull ring 18 is released, and the spring 17 rebounds, which can make the pin block 16 lock into the pin groove 14, thereby rotating and locking the rotating shaft 3 and the drum 4. In summary, the protective net 5 and multiple protective plates 8 attached and fixed to the slope can protect the slope, thereby reducing the risk of slope collapse. Even if the slope collapses, it can prevent falling rocks and soil from injuring the workers at the bottom of the slope.

[0032] When the protective net 5 needs to be stored, pull the pull ring 18 to one side. The pull ring 18 and multiple sliding rods 15 drive the pin block 16 to move laterally, so that the pin block 16 separates from the pin groove 14, thereby releasing the rotation lock state of the rotating shaft 3 and the drum 4. Start the drive motor 10, and the drive motor 10 drives the rotating shaft 3 and the drum 4 to rotate. The rotation of the drum 4 can be used to wind and store the protective net 5.

Positioning plates 6 and multiple first anchor rods 7 fix one end of the protective netting 5 to the bottom of the slope. Multiple second anchor rods 9 install multiple protective plates 8 on each step of the slope, thus protecting each step of the slope.
