Description

Technical Field

[0001] The present invention belongs to the field of slope repair, and specifically relates to a device and method for repairing mine slopes. Background Technique

[0002] The formation of mine slopes is an inevitable result in the process of open-pit mine mining. Open-pit mine mining usually divides ore and rock into horizontal layers of a certain thickness and mines them layer by layer from top to bottom. As mining progresses, the ore body is gradually stripped, forming a stepped bench structure. The slope parts of these benches are the mine slopes.

[0003] The stability control and ecological restoration of mine slopes are important links in mine safety production and environmental protection. In the treatment of mine slopes, wire meshing can be combined with reinforcement measures such as anchor rods and cables. By fixing the metal mesh on the slope surface, the overall stability of the slope is enhanced; the wire mesh can effectively prevent floating stones and crushed stones on the slope surface from rolling down, avoiding potential safety hazards caused by falling stones; the technology of spraying vegetation substrate after wire meshing is an important means for ecological restoration of mine slopes. By spraying vegetation substrate after wire meshing, vegetation growth is promoted and the slope ecological environment is improved.

[0004] In the traditional process of repairing mine slopes, if the method of wire mesh repair is used, the wire mesh needs to be laid on the slope first, and the operator needs to fix the wire mesh one by one on the slope. During the whole work process, safety ropes are required to protect the operator. This not only has a high risk, but also the dangerous operation will reduce work efficiency and waste a lot of labor costs.

[0005] Therefore, the present invention provides a device and method for repairing mine slopes. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background technique.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A device for repairing mine slopes according to the present invention includes a slope mesh, which is composed of multiple flexible slide rails. Adjacent flexible slide rails are connected by a plurality of covering mesh covers, and adjacent covering mesh covers are connected end to end. Fixing nails are arranged on the top surface of the covering mesh cover. The device further includes a first driving vehicle and a second driving vehicle. A horizontal platform is connected between the first driving vehicle and the second driving vehicle. A vertically arranged electric hammer is installed in the middle of the horizontal platform. A top plate for straightening the fixing nails is arranged outside the second driving vehicle. In the traditional process of repairing mine slopes, if the method of wire mesh repair is used, the wire mesh needs to be laid on the slope first, and the operator needs to fix the wire mesh one by one on the slope. During the whole work process, safety ropes are required to protect the operator. This not only has a high risk, but also the dangerous operation will reduce work efficiency and waste a lot of labor costs; The slope net is initially in a wound state. The slope net is thrown downward from the top of the slope so that the slope net covers the inclined slope. It is necessary to pull the slope net from the bottom and the top to ensure that the slope net is laid flat on the slope, and the distance between adjacent slope nets should not be too large. The slopes of mines are often relatively hard, and although the slopes of mines are relatively steep, the inclined surfaces are often relatively flat. The uneven parts need to be leveled in advance. Place the first driving vehicle and the second driving vehicle on two adjacent flexible slide rails. Pulley fasteners are installed at the bottoms of the first driving vehicle and the second driving vehicle to be stuck on the flexible slide rails, enabling the first driving vehicle and the second driving vehicle to move along the flexible slide rails. At the same time, start the first driving vehicle and the second driving vehicle to move on the flexible slide rails. The moving method can be from top to bottom or from bottom to top. Regardless of the moving method, the first driving vehicle and the second driving vehicle will pull the slope net downward, further ensuring that the slope net is laid flat on the slope. When the first driving vehicle and the second driving vehicle move to the fixing nails, use the top plate to straighten the fixing nails from one side of the fixing nails, and then use an electric hammer. The electric hammer can quickly and powerfully strike downward, and a cylinder structure or a hydraulic structure can be adopted. Thus, the fixing nails are passed through the covering net cover and fixed to the slope. As the first driving vehicle and the second driving vehicle continue to move, all the fixing nails can be driven into the slope, thereby fixing the slope net on the slope. After the slope net is laid, it can not only reinforce the slope soil body, reduce the damage and loss of the slope, but also the hung slope net can facilitate the later spraying of soil and plant seeds on the slope, quickly restore the slope vegetation, and form an ecological slope protection, which is both beautiful and environmentally friendly. Through this setting, not only the work of quickly fixing the slope net is realized, but also multiple first driving vehicles and second driving vehicles can be placed for synchronous operation to improve work efficiency. Moreover, since the fixing work is completed by machinery, it greatly reduces the problem of various potential safety hazards that are likely to occur when manual work is carried out on the slope due to the large slope inclination.

[0008] Preferably, a plurality of hollow holes are formed on the surface of the covering mesh, a fixing hole is formed in the middle of the covering mesh, a connecting ring is fixedly connected between the tip of the fixing nail and the covering mesh, and the cap end of the fixing nail is adhesively bonded to the covering mesh. The fixing nail is directly fixed on the covering mesh, which can not only increase the weight of the slope net, making it easier to unfold when the slope net unfolds and rolls downward, and the greater the gravity, the better the effect of unfolding and paving on the slope. At the same time, during the process of driving vehicle 1 and driving vehicle 2 driving nails, there is no need to carry fixing nails by themselves, and just straighten the fixing nails on the covering mesh. The cap end of the fixing nail is adhesively bonded to the covering mesh with glue. During the process of straightening the top plate, the adhesive part will break, ensuring that the fixing nail can be normally straightened. During the process of rolling up the slope net, the fixing nail is flush with the covering mesh, facilitating the normal storage of the fixing nail. The setting of the connecting ring enables the tip of the fixing nail to face the fixing hole when the tip is straightened, ensuring the accurate position when the fixing nail is inserted, and the connecting ring will break during the hammering process.

[0009] Preferably, inner grooves are formed on the opposite sides of driving vehicle 1 and driving vehicle 2, the top plate is located in the inner grooves, a driving motor for driving the top plate to rotate is installed on the top of driving vehicle 2, and a horizontally arranged trigger plate is rotatably connected to the bottom of the top plate. When driving vehicle 2 moves to the position of the fixing nail, the nail cap of the fixing nail will squeeze the trigger plate to rotate upward. A sensor is arranged between the trigger plate and the top plate, which can monitor the rotation state of the trigger plate, so as to know that driving vehicle 2 has moved above the fixing nail at this time. Then start the driving motor to drive the top plate to rotate. The rotation makes the top plate squeeze the surface of the nail cap of the fixing nail, rotating the fixing nail to a horizontal state, thus realizing the functions of accurately knowing the position of the fixing nail and straightening the fixing nail. The top plate is foldable. After the fixing nail is straightened, the top plate is bent and folded, so as not to interfere with the work of the electric hammer hitting the fixing nail.

[0010] Preferably, a horizontally arranged sliding groove is formed in the inner groove, an electric telescopic rod is fixedly connected in the sliding groove, and a fixing arm is fixedly connected to the end of the electric telescopic rod. When the fixing nail is half-lifted by the top plate, start the electric telescopic rod to push the fixing arm outwards. The two fixing arms approach each other and fix the fixing nail in the middle position to ensure the vertical state of the fixing nail. The fixing arm is made of flexible material and does not need to fit too tightly with the fixing nail during straightening, so that the fixing nail can be normally combined with the slope under hammering.

[0011] Preferably, the top plate is provided in sections. The two sections of the top plate are rotatably connected by a hinge. A locking valve is installed between the ends of the two sections of the top plate. An electric winding roller is fixedly connected to the outer side of the top plate near the top. A plurality of steel cables are fixedly connected to the outer side of the electric winding roller. The end of the steel cable is fixedly connected to the surface of the other section of the top plate. After the top plate semi-lifts the fixing nail, the two fixing arms extend outwards to straighten the fixing nail. At the same time, the locking valve of the top plate is released. At the same time, the electric winding roller winds the steel cable to fold the top plate. In this way, the top plate will not interfere with the electric hammer when rotating to the horizontal position. After the electric hammer hammers multiple times, the fixing arms and the top plate are sequentially retracted and reset, waiting for the next straightening operation.

[0012] Preferably, an inclined camera is fixedly connected to the outer side of the horizontal platform. The imaging end of the camera faces downwards. A level is fixedly connected to the top of the horizontal platform. A motor box for adjusting the horizontal platform is fixedly connected to the top of the first driving vehicle. By observing the position of the fixing nail through the camera, it is ensured that the electric hammer can correctly hammer the fixing nail. At the same time, the level can measure the horizontal state of the horizontal platform. The horizontal platform and the electric hammer have the same inclination as the slope. When encountering an uneven area of the slope, a height difference between the first driving vehicle and the second driving vehicle will cause the electric hammer not to be perpendicular to the fixing nail, which is likely to cause problems during the hammering process. At this time, the motor box is started to drive the horizontal platform to rotate, so that the level returns to the previous inclination; the inclination of the slope often remains the same. Adjustment is made when the data changes, or adjustment can also be made according to the observation of the camera, so as to ensure that the electric hammer can stably drive the fixing nail into the slope.

[0013] Preferably, the output end of the motor box is fixedly connected to a first connecting block. The end of the first connecting block is fixedly connected to the horizontal platform. A second connecting block is fixedly connected between the horizontal platform and the end of the second driving vehicle. Both the first connecting block and the second connecting block are made of elastic materials. Since it is difficult to ensure that the first driving vehicle and the second driving vehicle are completely synchronized, the horizontal platform is supported by the elastic first connecting block and second connecting block. In this way, when the first driving vehicle and the second driving vehicle are displaced, the first connecting block and the second connecting block will deform, and still can stably support the horizontal platform. And the elastic support can twist in any direction to adapt to the complex slope environment.

[0014] Preferably, a nail head plate is fixedly connected to the cap end of the fixing nail. Two binding ropes are fixedly connected to the middle of the covering net cover. A socket ring is fixedly connected between the ends of the two binding ropes. The socket ring is fixedly connected to the nail head plate. A plurality of barb plates are fixedly connected to the middle of the fixing nail; the nail head plate is used to increase the stress surface of the fixing nail, facilitating the top plate to turn the fixing nail upwards. The binding ropes bind the fixing nail, so that the fixing nail can only move on one plane during the straightening process and will not fall around, further ensuring that the fixing nail can be accurately driven into the slope.

[0015] A method for repairing a mine slope, specifically: S1: Throw the slope net down from the top of the slope so that the slope net covers the inclined slope. Place the driving vehicle 1 and the driving vehicle 2 on two adjacent flexible slide rails. Pulley fasteners are installed at the bottoms of the driving vehicle 1 and the driving vehicle 2 for clamping on the flexible slide rails, enabling the driving vehicle 1 and the driving vehicle 2 to move along the flexible slide rails; S2: When the driving vehicle 2 moves to the position of the fixing nail, the nail cap of the fixing nail will squeeze the trigger plate to rotate upward, thereby indicating that the driving vehicle 2 has moved above the fixing nail at this time; S3: After the driving vehicle 1 and the driving vehicle 2 move onto the fixing nail, use the top plate and the fixing arm to straighten the fixing nail from one side of the fixing nail. Then use an electric hammer, which can strike downward quickly and powerfully, to drive the fixing nail through the covering mesh and fix it to the slope. As the driving vehicle 1 and the driving vehicle 2 continue to move, all the fixing nails can be driven into the slope, thus fixing the slope net to the slope.

[0016] The specific method for the top plate and the fixing arm in S to straighten the fixing nail is as follows: Q1: Start the driving motor to drive the top plate to rotate. The rotation causes the top plate to squeeze the surface of the nail cap of the fixing nail, rotating the fixing nail to a horizontal state; when the fixing nail is half-lifted by the top plate, start the electric telescopic rod to push the fixing arm outwards. The two fixing arms approach each other and fix the fixing nail at the middle position; Q2: After the top plate half-lifts the fixing nail, the two fixing arms extend outwards to straighten the fixing nail. At the same time, the locking valve of the top plate is released, and the electric winding roller winds up the steel cable to fold the top plate, so that the top plate will not interfere with the electric hammer when rotating to the horizontal position.

[0017] The beneficial effects of the present invention are as follows: 1. A mine slope repair device and method according to the present invention, through the settings of a covering net, a flexible slide rail, a first driving vehicle and a second driving vehicle, the first driving vehicle and the second driving vehicle can move along the flexible slide rail. At the same time, when the first driving vehicle and the second driving vehicle are started to move on the flexible slide rail, the moving mode can be from top to bottom or from bottom to top. No matter what the moving mode is, the first driving vehicle and the second driving vehicle will pull the slope net downward, further ensuring that the slope net is laid flat on the slope. When the first driving vehicle and the second driving vehicle move to the fixing nails, use the top plate to straighten the fixing nails from one side of the fixing nails, and then use an electric hammer, which can quickly and powerfully strike downward, and a cylinder structure or a hydraulic structure can be adopted; thus, the fixing nails are passed through the covering net and fixed to the slope. As the first driving vehicle and the second driving vehicle continue to move, all the fixing nails can be driven into the slope, so as to fix the slope net on the slope. After the slope net is laid, it can not only reinforce the slope soil body, reduce the damage and loss of the slope, but also the hung slope net can facilitate the later spraying of soil and plant seeds on the slope, quickly restore the slope vegetation, form an ecological slope protection, which is both beautiful and environmentally friendly; through this setting, not only the work of quickly fixing the slope net is realized, but also multiple first driving vehicles and second driving vehicles can be placed for synchronous operation to improve the work efficiency; and because the fixing work is completed by machinery, it greatly reduces the problem of various potential safety hazards that are likely to occur when manual work is carried out on the slope due to the large slope inclination.

[0018] 2. A mine slope repair device and method according to the present invention directly fixes the fixing nails on the covering net. In this way, not only can the weight of the slope net be increased, making it more convenient to unfold while the slope net unfolds and rolls downward, and the greater the gravity, the better the effect of unfolding and paving on the slope. At the same time, in the process of driving the first driving vehicle and the second driving vehicle to drive the nails, there is no need to carry the fixing nails by itself, and just straighten the fixing nails on the covering net; the cap end of the fixing nail is adhesively bonded to the covering net. During the process of straightening the top plate, the adhesive joint will break, ensuring that the fixing nail can be normally straightened. During the process of winding up the slope net, the fixing nail is flush with the covering net, which is convenient for the normal storage of the fixing nail. The setting of the connecting ring makes the tip of the fixing nail face the fixing hole when the tip is straightened, ensuring the accurate position when the fixing nail is inserted.

Specific implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] As Figures 1 to 7 shown, a mine slope repair device described in an embodiment of the present invention includes a slope net 1, the slope net 1 is composed of a plurality of flexible slide rails 6, and adjacent flexible slide rails 6 are connected by a plurality of covering net covers 4, and adjacent covering net covers 4 are connected end to end. Fixing nails 5 are arranged on the top surface of the covering net cover 4. The device further includes a first driving vehicle 2 and a second driving vehicle 3. A horizontal platform 15 is connected between the first driving vehicle 2 and the second driving vehicle 3. A vertically arranged electric hammer 7 is installed in the middle of the horizontal platform 15. A top plate 16 for straightening the fixing nail 5 is arranged outside the second driving vehicle 3; The slope net 1 is initially in a retracted state. The slope net 1 is thrown downward from the top of the slope so that the slope net 1 covers the inclined slope. It is necessary to pull the slope net 1 from the bottom and the top to ensure that the slope net 1 is laid flat on the slope, and the distance between adjacent slope nets 1 should not be too large. The slopes of mines are often relatively hard, and although the slopes of mines are relatively steep, the inclined surfaces are often relatively flat. Uneven parts need to be leveled in advance. Place the first driving vehicle 2 and the second driving vehicle 3 on two adjacent flexible slide rails 6. Pulley fasteners are installed at the bottoms of the first driving vehicle 2 and the second driving vehicle 3 for clamping on the flexible slide rails 6, so that the first driving vehicle 2 and the second driving vehicle 3 can move along the flexible slide rails 6. At the same time, start the first driving vehicle 2 and the second driving vehicle 3 to move on the flexible slide rails 6. The moving method can be from top to bottom or from bottom to top. No matter which moving method, the first driving vehicle 2 and the second driving vehicle 3 will pull the slope net 1 downward, further ensuring that the slope net 1 is laid flat on the slope. When the first driving vehicle 2 and the second driving vehicle 3 move to the fixing nails 5, use the top plate 16 to straighten the fixing nails 5 from one side of the fixing nails 5, and then use the electric hammer 7. The electric hammer 7 can quickly and powerfully strike downward and can adopt a cylinder structure or a hydraulic structure. Thus, the fixing nails 5 are passed through the covering mesh cover 4 and fixed to the slope. As the first driving vehicle 2 and the second driving vehicle 3 continue to move, all the fixing nails 5 can be driven into the slope, thereby fixing the slope net 1 on the slope. After the slope net 1 is laid, it can not only reinforce the slope soil body, reduce the damage and loss of the slope, but also the hung slope net 1 can facilitate the later spraying of soil and plant seeds on the slope, quickly restore the slope vegetation, and form an ecological slope protection, which is both beautiful and environmentally friendly. Through this setting, not only the work of quickly fixing the slope net 1 is realized, but also multiple first driving vehicles 2 and second driving vehicles 3 can be placed for synchronous operation to improve work efficiency. And because the fixing work is completed by machinery, it greatly reduces the problems of various safety hazards that are likely to occur when workers operate on the slope due to the large inclination of the slope.

[0023] A plurality of hollow holes are formed on the surface of the covering mesh cover 4, a fixing hole 19 is formed in the middle of the covering mesh cover 4, a connecting ring 20 is fixedly connected between the tip of the fixing nail 5 and the covering mesh cover 4, and the cap end of the fixing nail 5 is adhesively bonded to the covering mesh cover 4; During operation, the fixing nail 5 is directly fixed on the covering mesh 4. This not only increases the weight of the slope net 1, making it more convenient to unfold when the slope net 1 unfolds and rolls downwards, and the greater the gravity, the better the effect of unfolding and flattening on the slope. At the same time, during the nail driving process of the driving vehicle one 2 and the driving vehicle two 3, there is no need to carry the fixing nail 5 by itself, and it is only necessary to straighten the fixing nail 5 on the covering mesh 4; the cap end of the fixing nail 5 is adhesively bonded to the covering mesh 4 with glue. During the straightening process of the top plate 16, the adhesive joint will break, ensuring that the fixing nail 5 can be normally straightened. During the winding process of the slope net 1, the fixing nail 5 is flush with the covering mesh 4, facilitating the normal storage of the fixing nail 5. The setting of the connecting ring 20 enables the tip of the fixing nail 5 to face the fixing hole 19 when the tip is straightened, ensuring the accurate position when the fixing nail 5 is inserted, and the connecting ring 20 will break during the hammering process.

[0024] Inner grooves 17 are respectively formed on the opposite sides of the driving vehicle one 2 and the driving vehicle two 3. The top plate 16 is located in the inner groove 17. A driving motor for driving the top plate 16 to rotate is installed on the top of the driving vehicle two 3. The bottom of the top plate 16 is rotatably connected to a horizontally arranged trigger plate 18. During operation, when the driving vehicle two 3 moves to the position of the fixing nail 5, the nail cap of the fixing nail 5 will squeeze the trigger plate 18 to rotate upwards. A sensor is provided between the trigger plate 18 and the top plate 16, which can monitor the rotation state of the trigger plate 18, thereby knowing that the driving vehicle two 3 has moved above the fixing nail 5 at this time. Then, the driving motor is started to drive the top plate 16 to rotate. The rotation causes the top plate 16 to press the surface of the nail cap of the fixing nail 5, rotating the fixing nail 5 to a horizontal state, thus realizing the functions of accurately knowing the position of the fixing nail 5 and straightening the fixing nail 5. The top plate 16 is foldable. After the fixing nail 5 is straightened, the top plate 16 is bent and folded, so as not to interfere with the work of the electric hammer 7 hitting the fixing nail 5.

[0025] A horizontally arranged sliding groove is formed in the inner groove 17. An electric telescopic rod is fixedly connected in the sliding groove, and the end of the electric telescopic rod is fixedly connected with a fixing arm 13. During operation, when the fixing nail 5 is half-lifted by the top plate 16, the electric telescopic rod is started to push the fixing arm 13 outwards. The two fixing arms 13 approach each other and fix the fixing nail 5 at the middle position, ensuring the vertical state of the fixing nail 5. The fixing arm 13 is made of a flexible material, and it is not necessary to fit tightly with the fixing nail 5 during straightening, allowing the fixing nail 5 to be normally combined with the slope under hammering.

[0026] The top plate 16 is arranged in sections. The two sections of the top plate 16 are rotatably connected by a hinge. A locking valve is installed between the ends of the two sections of the top plate 16. An electric winding roller is fixedly connected to the outer side of the top plate 16 near the top. A plurality of steel cables 24 are fixedly connected to the outer side of the electric winding roller. The end of the steel cable 24 is fixedly connected to the surface of the other section of the top plate 16; During operation, when the top plate 16 half-lifts the fixing nail 5, the two fixing arms 13 extend outwards to straighten the fixing nail 5. At the same time, the locking valve of the top plate 16 is released, and the electric winding roller winds up the steel cable 24 to fold the top plate 16. In this way, the top plate 16 will not obstruct the electric hammer 7 when rotating to the horizontal position. After the electric hammer 7 hammers multiple times, the fixing arms 13 and the top plate 16 are sequentially retracted and reset, waiting for the next straightening operation.

[0027] An inclined camera 10 is fixedly connected to the outer side of the horizontal platform 15. The imaging end of the camera 10 faces downwards. A level 11 is fixedly connected to the top of the horizontal platform 15. A motor box 8 for adjusting the horizontal platform 15 is fixedly connected to the top of the driving vehicle one 2; During operation, the position of the fixing nail 5 is observed through the camera 10 to ensure that the electric hammer 7 can correctly hammer the fixing nail 5. At the same time, the level 11 can measure the horizontal state of the horizontal platform 15. Both the horizontal platform 15 and the electric hammer 7 have the same inclination as the slope. When encountering an uneven area of the slope, a height difference between the driving vehicle one 2 and the driving vehicle two 3 will occur, which will cause the electric hammer 7 not to be perpendicular to the fixing nail 5 and easily lead to problems during the hammering process. At this time, the motor box 8 is started to drive the horizontal platform 15 to rotate, so that the level 11 returns to the previous inclination; the inclination of the slope often remains the same. When the data changes, adjustments are made, or adjustments can also be made according to the observation of the camera 10, so as to ensure that the electric hammer 7 can stably drive the fixing nail 5 into the slope.

[0028] The output end of the motor box 8 is fixedly connected to a connecting block one 9. The end of the connecting block one 9 is fixedly connected to the horizontal platform 15. A connecting block two 12 is fixedly connected between the horizontal platform 15 and the end of the driving vehicle two 3. Both the connecting block one 9 and the connecting block two 12 are made of elastic materials; During operation, since it is difficult to ensure that the driving vehicle one 2 and the driving vehicle two 3 are completely synchronized, the horizontal platform 15 is supported by the elastic connecting block one 9 and connecting block two 12. In this way, when the driving vehicle one 2 and the driving vehicle two 3 are offset, the connecting block one 9 and the connecting block two 12 will deform, and still can stably support the horizontal platform 15. Moreover, the elastic support can twist in any direction to adapt to the complex slope environment.

[0029] A nail head plate 22 is fixedly connected to the cap end of the fixing nail 5. Two binding ropes 21 are fixedly connected to the middle of the covering mesh 4. A socket ring is fixedly connected between the ends of the two binding ropes 21. The socket ring is fixedly connected to the nail head plate 22. A plurality of barb plates 23 are fixedly connected to the middle of the fixing nail 5; During operation, the nail head plate 22 is used to increase the force-bearing surface of the fixing nail 5, facilitating the top plate 16 to turn the fixing nail 5 upward. The restraint rope 21 restrains the fixing nail 5, enabling the fixing nail 5 to move only in one plane during the straightening process without wobbling, further ensuring that the fixing nail 5 can be accurately driven into the slope. Multiple barbs are fixedly connected to the surface of the barb plate 23 to ensure that after the fixing nail 5 is inserted into the soil mass, it can effectively grip the soil mass and improve the fixing firmness of the fixing nail 5.

[0030] A method for repairing a mine slope, specifically as follows: S1: Throw the slope net 1 downward from the top of the slope, allowing the slope net 1 to cover the inclined slope. Place the driving vehicle 1 2 and the driving vehicle 2 3 on two adjacent flexible slide rails 6. Pulley fasteners are installed at the bottoms of the driving vehicle 1 2 and the driving vehicle 2 3 for clamping on the flexible slide rails 6, enabling the driving vehicle 1 2 and the driving vehicle 2 3 to move along the flexible slide rails 6; S2: When the driving vehicle 2 3 moves to the position of the fixing nail 5, the nail cap of the fixing nail 5 will squeeze the trigger plate 18 to rotate upward, thereby indicating that the driving vehicle 2 3 has moved above the fixing nail 5 at this time; S3: After the driving vehicle 1 2 and the driving vehicle 2 3 move onto the fixing nail 5, use the top plate 16 and the fixing arm 13 to straighten the fixing nail 5 from one side of the fixing nail 5. Then use the electric hammer 7, which can quickly and powerfully strike downward, thereby driving the fixing nail 5 through the covering mesh 4 and fixing it to the slope. As the driving vehicle 1 2 and the driving vehicle 2 3 continue to move, all the fixing nails 5 can be driven into the slope, thus fixing the slope net 1 on the slope.

[0031] The specific method for the top plate 16 and the fixing arm 13 to straighten the fixing nail 5 in S3 is as follows: Q1: Start the driving motor to drive the top plate 16 to rotate. The rotation causes the top plate 16 to squeeze the surface of the nail cap of the fixing nail 5, rotating the fixing nail 5 to a horizontal state; when the fixing nail 5 is half-lifted by the top plate 16, start the electric telescopic rod to push the fixing arm 13 outward. The two fixing arms 13 approach each other and fix the fixing nail 5 at the middle position; Q2: When the top plate 16 half-raises the fixing nail 5, the two fixing arms 13 extend outward to straighten the fixing nail 5. At the same time, the locking valve of the top plate 16 is released, and the electric winding roller winds up the steel cable 24 to fold the top plate 16, so that the top plate 16 will not interfere with the electric hammer 7 when rotating to the horizontal position.

[0032] During operation, the slope net 1 is initially in a wound state. The slope net 1 is thrown downward from the top of the slope so that the slope net 1 covers the inclined slope. It is necessary to pull the slope net 1 from the bottom and the top to ensure that the slope net 1 is laid flat on the slope, and the distance between adjacent slope nets 1 should not be too large. The slopes of mines are often relatively hard, and although the slopes of mines are relatively steep, the inclined surfaces are often relatively flat. The uneven parts need to be leveled in advance. Place the first driving vehicle 2 and the second driving vehicle 3 on two adjacent flexible slide rails 6. Pulley fasteners are installed at the bottoms of the first driving vehicle 2 and the second driving vehicle 3 for clamping on the flexible slide rails 6, so that the first driving vehicle 2 and the second driving vehicle 3 can move along the flexible slide rails 6. At the same time, start the first driving vehicle 2 and the second driving vehicle 3 to move on the flexible slide rails 6. The moving method can be from top to bottom or from bottom to top. No matter what the moving method is, the first driving vehicle 2 and the second driving vehicle 3 will pull the slope net 1 downward, further ensuring that the slope net 1 is laid flat on the slope. When the first driving vehicle 2 and the second driving vehicle 3 move to the fixing nails 5, use the top plate 16 to straighten the fixing nails 5 from one side of the fixing nails 5, and then use the electric hammer 7. The electric hammer 7 can quickly and powerfully strike downward, and a cylinder structure or a hydraulic structure can be adopted. Thus, the fixing nails 5 are passed through the covering net cover 4 and fixed to the slope. As the first driving vehicle 2 and the second driving vehicle 3 continue to move, all the fixing nails 5 can be driven into the slope, thereby fixing the slope net 1 on the slope. After the slope net 1 is laid, it can not only reinforce the slope soil body, reduce the damage and loss of the slope, but also the hung slope net 1 can facilitate the later spraying of soil and plant seeds on the slope, quickly restore the slope vegetation, and form an ecological slope protection, which is both beautiful and environmentally friendly. Through this setting, not only the work of quickly fixing the slope net 1 is realized, but also multiple first driving vehicles 2 and second driving vehicles 3 can be placed for synchronous operation to improve work efficiency. And because the fixing work is completed by machinery, it greatly reduces the problems of various safety hazards that are likely to occur when workers operate on the slope due to the large slope inclination. The fixing nails 5 are directly fixed on the covering net cover 4. In this way, it can not only increase the weight of the slope net 1, making it more convenient to unfold while the slope net 1 unfolds and rolls downward, and the greater the gravity, the better the effect of unfolding and paving flat on the slope. At the same time, in this way, during the nailing process of the first driving vehicle 2 and the second driving vehicle 3, there is no need to carry the fixing nails 5 by itself, and just straighten the fixing nails 5 on the covering net cover 4. The cap end of the fixing nail 5 and the covering net cover 4 are bonded by glue. During the straightening process of the top plate 16, the bonded part will break, ensuring that the fixing nail 5 can be normally straightened. During the winding process of the slope net 1, the fixing nail 5 is flush with the covering net cover 4, which is convenient for the normal storage of the fixing nail 5. The setting of the connecting ring 20 enables the tip of the fixing nail 5 to face the fixing hole 19 when the tip is straightened, ensuring the accurate position when the fixing nail 5 is inserted. The connecting ring 20 will break during the hammering process. When the driving vehicle two 3 moves to the position of the fixing nail 5, the nail cap of the fixing nail 5 will squeeze the trigger plate 18 to rotate upward. A sensor is arranged between the trigger plate 18 and the top plate 16, which can monitor the rotation state of the trigger plate 18, so as to know that the driving vehicle two 3 has moved above the fixing nail 5 at this time. Then, the driving motor is started to drive the top plate 16 to rotate. The rotation makes the top plate 16 squeeze the surface of the nail cap of the fixing nail 5, and rotates the fixing nail 5 to a horizontal state, thus realizing the functions of accurately knowing the position of the fixing nail 5 and straightening the fixing nail 5. The top plate 16 is foldable. After the fixing nail 5 is straightened, the top plate 16 bends and folds, so that it will not interfere with the operation of the electric hammer 7 hitting the fixing nail 5; When the fixing nail 5 is half-lifted by the top plate 16, the electric telescopic rod is started to push the fixing arm 13 outwards. The two fixing arms 13 approach each other and fix the fixing nail 5 in the middle position to ensure the vertical state of the fixing nail 5. The fixing arm 13 is made of flexible material. When straightening, it does not need to fit tightly with the fixing nail 5, so that the fixing nail 5 can be normally combined with the slope under hammering; After the top plate 16 half-lifts the fixing nail 5, the two fixing arms 13 extend outwards to straighten the fixing nail 5. At the same time, the locking valve of the top plate 16 is released, and the electric winding roller winds up the steel cable 24 to fold the top plate 16. In this way, the top plate 16 will not interfere with the electric hammer 7 when it rotates to the horizontal position. After the electric hammer 7 hammers many times, the fixing arm 13 and the top plate 16 are recycled and reset in sequence, waiting for the next straightening work; The position of the fixing nail 5 is observed through the camera 10 to ensure that the electric hammer 7 can correctly hammer the fixing nail 5. At the same time, the level 11 can measure the horizontal state of the horizontal platform 15. The horizontal platform 15 and the electric hammer 7 have the same inclination as the slope. When encountering an uneven area of the slope, which causes a height difference between the driving vehicle one 2 and the driving vehicle two 3, it will cause the electric hammer 7 not to be perpendicular to the fixing nail 5, easily resulting in problems during the hammering process. At this time, the motor box 8 is started to drive the horizontal platform 15 to rotate, so that the level 11 returns to the previous inclination; the inclination of the slope is often consistent. When the data changes, it is adjusted, or it can also be adjusted according to the observation of the camera 10, so as to ensure that the electric hammer 7 can stably drive the fixing nail 5 into the slope; Since it is difficult to ensure that the driving vehicle one 2 and the driving vehicle two 3 are completely synchronized, the horizontal platform 15 is supported by the elastic connecting block one 9 and the connecting block two 12. In this way, when the driving vehicle one 2 and the driving vehicle two 3 are offset, the connecting block one 9 and the connecting block two 12 will deform, and still can stably support the horizontal platform 15, and the elastic support can twist in any direction to adapt to the complex slope environment; The nail head plate 22 is used to increase the stress surface of the fixing nail 5, facilitating the top plate 16 to turn the fixing nail 5 upward. The restraint rope 21 restrains the fixing nail 5, enabling the fixing nail 5 to move only in one plane during the righting process without tipping over, further ensuring that the fixing nail 5 can be accurately nailed into the slope. The surface of the barb plate 23 is fixedly connected with a plurality of barbs, which are used to ensure that the fixing nail 5 can effectively grip the soil after being inserted into the soil, improving the fixing firmness of the fixing nail 5.
