Specific implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 7As shown in the figure, a slope protection device with a warning function for open-pit mining includes a plurality of cement piers 7. At the top of each of the plurality of cement piers 7, a connecting plate 6 is fixedly connected. The connecting plate 6 is fixedly connected to the bottom end of a steel column 1. One side of the steel column 1 is fixedly connected to a clamping plate 2 by a bolt 9. A wire rope net 3 is abutted between the steel column 1 and the clamping plate 2. A plurality of first guide rods 4 are equidistantly arranged on the steel column 1. The ends of the plurality of first guide rods 4 are engaged in the clamping plate 2. The first guide rods 4 are slidably connected to the wire rope net 3. A warning structure 8 is installed at the top end of one of the steel columns 1. The steel column 1 is installed on the cement pier 7, and then the wire rope net 3 is passed through the first guide rods 4, so that the first guide rods 4 play a role in initially fixing the wire rope net 3. Then, the clamping plate 2 is aligned with the steel column 1, and the clamping plate 2 is moved towards the steel column 1 until the clamping plate 2 abuts tightly against the wire rope net 3. At the same time, the clamping plate 2 is engaged with the ends of the first guide rods 4, so that the clamping plate 2 is initially fixed. Then, the bolt 9 is used to further fix the steel column 1 and the clamping plate 2, so that the steel column 1 and the clamping plate 2 clamp the wire rope net 3, making the wire rope net 3 unable to slip off, increasing the contact area between the steel column 1 and the wire rope net 3, and thus improving the stability of the fixation of the wire rope net 3. When the wire rope net 3 is damaged or the length is insufficient, the two ends of a newly added piece of wire rope net 3 can be directly clamped and fixed by the steel column 1 and the clamping plate 2, without using a sewing rope for sewing, and the operation is simple and flexible, improving the construction efficiency.

[0024] As a technical optimization scheme of the present utility model, the cross-section of the steel column 1 is in an "I" - shaped structure, and the end of the first guide rod 4 is in a conical structure. The conical structure of the end of the first guide rod 4 has a guiding effect on the clamping plate 2, facilitating the positioning of the clamping plate 2 and facilitating the use of the bolt 9 to fix the clamping plate 2.

[0025] As a technical optimization scheme of the present utility model, a second rubber pad 11 is installed on one side of the steel column 1 facing the wire rope net 3, and a first rubber pad 10 is installed on one side of the clamping plate 2 facing the wire rope net 3. Both the first rubber pad 10 and the second rubber pad 11 are abutted against the wire rope net 3. When the bolt 9 is used to fix the steel column 1 and the clamping plate 2 after the clamping plate 2 abuts tightly against the wire rope net 3, the first rubber pad 10 and the second rubber pad 11 abut against the wire rope net 3 from both sides of the wire rope net 3 towards the middle of the wire rope net 3. The first rubber pad 10 and the second rubber pad 11 can increase the friction between the steel column 1 and the clamping plate 2 and the wire rope net 3, making the fixation of the steel column 1 and the clamping plate 2 on the wire rope net 3 more firm and increasing the stability of the wire rope net 3.

[0026] As a technical optimization scheme of the present utility model, two identical cross plates 12 are connected between every three steel columns 1, and the two cross plates 12 are linearly distributed up and down. The installation of the cross plates 12 effectively increases the stability of the steel columns 1, thereby making the entire slope protection device more stable.

[0027] As a technical optimization solution of the utility model, three warning strips 5 are installed on the clamp plate 2, and the three warning strips 5 are linearly distributed up and down. The warning structure 8 includes a slot 803, and a slot 803 is opened at the top of one of the steel columns 1. A block 802 is engaged in the slot 803, and the block 802 is installed at the bottom of the solar warning light 801. A limited block 804 is slidably connected to the steel column 1, and a limited slot 805 is opened on the block 802. The limit block 804 is engaged in the limit slot 805. The end of the block 802 facing the outside of the steel column 1 is fixedly connected with a pull plate 806, and the side of the pull plate 806 facing the steel column 1 is fixedly connected with a tension spring 807, and the other end of the tension spring 807 is fixedly connected to the steel column 1, and the steel column 1 is fixedly connected with a second guide rod 808, and the pull plate 806 is slidably connected to the second guide rod 808, and the tension spring 807 is sleeved on the outside of the second guide rod 808; when installing the solar warning light 801, hold the solar warning light 801 and align the block 802 at its bottom with the The card slot 803 at the top of the steel column 1, and then the solar warning light 801 is pressed downward. After the card block 802 enters the card slot 803, the card block 802 resists the limit block 804 and slides toward the outside of the steel column 1. The limit block 804 drives the pull plate 806 to slide on the second guide rod 808 in the direction away from the steel column 1. At the same time, the pull plate 806 drives the tension spring 807 to extend, and the card block 802 is continuously pressed until the limit slot 805 on the card block 802 is aligned with the limit block 804, the resistance is lost, and the tension spring 807 is reset, driving the pull plate 806 to the steel column 1, and at the same time, the pull plate 806 drives the limit block 804 to slide toward the inside of the steel column 1 until the limit block 804 is engaged in the limit groove 805, thereby quickly completing the installation of the solar warning light 801. The operation is simple and convenient, and when the solar warning light 801 is damaged, it is convenient to disassemble and repair, thereby improving the efficiency of installing and disassembling the solar warning light 801. The setting of the solar warning light 801 and the warning strip 5 can serve as a warning reminder to the miners, making them more cautious when working on the slope during open-pit mining production.

[0028] When the utility model is in use, the steel column 1 is installed on the cement pier 7, and then the wire rope net 3 is penetrated through the first guide rod 4, so that the first guide rod 4 plays a role in initially fixing the wire rope net 3. Then, the clamping plate 2 is aligned with the steel column 1, and the clamping plate 2 is moved towards the steel column 1 until the clamping plate 2 abuts against the wire rope net 3. At the same time, the clamping plate 2 is engaged with the end of the first guide rod 4, so that the clamping plate 2 is initially fixed. Then, the steel column 1 and the clamping plate 2 are further fixed by using bolts 9, so that the steel column 1 and the clamping plate 2 clamp the wire rope net 3, preventing the wire rope net 3 from slipping off, increasing the contact area between the steel column 1 and the wire rope net 3, and thus improving the stability of the fixation of the wire rope net 3. When the wire rope net 3 is damaged or its length is insufficient, it can be directly clamped and fixed at both ends of a newly added piece of wire rope net 3 through the steel column 1 and the clamping plate 2 without using a sewing rope for sewing, with simple and flexible operation and improved construction efficiency; when the steel column 1 and the clamping plate 2 are fixed by using bolts 9 after the clamping plate 2 abuts against the wire rope net 3, the first rubber pad 10 and the second rubber pad 11 abut against the wire rope net 3 from both sides of the wire rope net 3 towards the middle of the wire rope net 3. The first rubber pad 10 and the second rubber pad 11 can increase the friction force between the steel column 1 and the clamping plate 2 and the wire rope net 3, making the fixation of the steel column 1 and the clamping plate 2 on the wire rope net 3 more firm and increasing the stability of the wire rope net 3; when installing the solar warning light 801, hold the solar warning light 801, align the block 802 at its bottom end with the slot 803 at the top end of the steel column 1, and then press the solar warning light 801 downward. After the block 802 enters the slot 803, the block 802 abuts against the limiting block 804 and slides outward of the steel column 1. The limiting block 804 drives the pull plate 806 to slide away from the steel column 1 on the second guide rod 808. At the same time, the pull plate 806 drives the tension spring 807 to elongate. Continuously press the block 802 until the limiting slot 805 on the block 802 aligns with the limiting block 804, then the abutting force is lost, the tension spring 807 resets, drives the pull plate 806 to move towards the steel column 1, and at the same time, the pull plate 806 drives the limiting block 804 to slide towards the inside of the steel column 1 until the limiting block 804 is engaged in the limiting slot 805, thus quickly completing the installation of the solar warning light 801, with simple and convenient operation. And when the solar warning light 801 is damaged, it is convenient to disassemble and repair, thus improving the efficiency of installing and disassembling the solar warning light 801; the installation of the cross plate 12 effectively increases the stability of the steel column 1, making the entire slope protection device more stable.
