Description

Technical Field

[0001] The present invention belongs to the field of slope repair, in particular to a mine slope repair device and method. Background Art

[0002] The formation of mine slopes is an inevitable result of open-pit mining. Open-pit mining usually divides the ore 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 away, forming a stepped step structure. The slope part of these steps is the mine slope.

[0003] Mine slope stability management and ecological restoration are crucial components of mine safety and environmental protection. In mine slope management, mesh can be used in conjunction with reinforcement measures such as anchor rods and cables. By securing the metal mesh to the slope, the overall stability of the slope is enhanced. The mesh can effectively prevent floating rocks and gravel from rolling off the slope, thus avoiding potential safety hazards caused by rockfall. The mesh-based ecological greening technology is an important method for mine slope ecological restoration. By spraying vegetation substrate after mesh installation, vegetation growth is promoted and the slope's ecological environment is improved.

[0004] In the traditional mine slope repair process, if the hanging net repair method is used, the hanging net needs to be laid on the slope first, and the operator needs to fix the hanging nets one by one on the slope. A safety rope needs to be used to protect the operator throughout the entire work process. This is not only highly dangerous, but also dangerous operations will reduce work efficiency and waste a lot of manpower costs.

[0005] To this end, the present invention provides a mine slope repairing device and method. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: the mine slope repair device described in the present invention includes a slope net, the slope net is composed of a plurality of flexible slide rails, adjacent flexible slide rails are connected by a plurality of covering mesh covers, adjacent covering mesh covers are connected end to end, and fixing nails are provided on the top surface of the covering mesh covers. The device also 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 vertical electric hammer is installed in the middle of the horizontal platform, and a top plate for straightening the fixing nails is provided on the outer side of the second driving vehicle;

[0008] In the traditional mine slope repair process, if the hanging net repair method is used, the hanging net must be laid on the slope first, and the operator must fix the hanging net one by one on the slope. The entire process requires the use of a safety rope to protect the operator. This is not only highly dangerous, but also reduces work efficiency and wastes a lot of manpower costs.

[0009] The slope net is initially in a rolled-up state, and the slope net is thrown downward from the top of the slope to cover the inclined slope. The slope net needs to be pulled from the bottom and the top to ensure that the slope net is laid flat on the slope, and the spacing between adjacent slope nets needs to be not 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, and the uneven parts need to be leveled in advance; the driving car one and the driving car two are placed on two adjacent flexible slide rails, and the bottoms of the driving car one and the driving car two are equipped with pulley clamps for clamping on the flexible slide rails, so that the driving car one and the driving car two can move along the flexible slide rails, and the driving car one and the driving car two are started at the same time to move on the flexible slide rails. The movement mode can be from top to bottom or from bottom to top. No matter which movement mode is used, the driving car one and the driving car two will pull the slope net downward to further ensure that the slope net is laid flat on the slope. After the vehicle 2 moves to the fixing nail, the top plate is used to straighten the fixing nail from one side of the fixing nail, and then an electric hammer is used. The electric hammer can strike downward quickly and forcefully, and a cylinder structure or a hydraulic structure can be used; thereby, the fixing nail is fixed to the slope through the covering mesh cover. As the driving vehicle 1 and the driving vehicle 2 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 and reduce the damage and loss of the slope, but also facilitate the subsequent spraying of soil and plant seeds on the slope, which can quickly restore the slope vegetation and form an ecological slope protection, which is both beautiful and environmentally friendly. Through this arrangement, not only the work of quickly fixing the slope net is achieved, but also multiple driving vehicles 1 and 2 can be placed at the same time for synchronous operation, thereby improving work efficiency. Moreover, since the fixing work is completed by machinery, the problem of various safety hazards that may occur easily due to the large inclination of the slope when manual work is carried out on the slope is greatly reduced.

[0010] Preferably, the surface of the covering mesh cover is provided with a plurality of hollow holes, the middle part of the covering mesh cover is provided with a fixing hole, a connecting ring is fixedly connected between the tip of the fixing nail and the covering mesh cover, and the cap end of the fixing nail is bonded to the covering mesh cover, so that the fixing nail is directly fixed to the covering mesh cover. This not only increases the weight of the slope net, but also makes it easier to unfold the slope net when it is unfolded and rolled down. Moreover, the greater the gravity, the better the effect of flattening it on the slope. At the same time, in the process of nailing by driving vehicle one and driving vehicle two, there is no need to carry the fixing nails themselves, and the fixing nails on the covering mesh cover can be directly straightened; the cap end of the fixing nail is bonded to the covering mesh cover by glue, and during the process of straightening the top plate, the adhesion will be broken, ensuring that the fixing nail can be normally straightened, and during the process of rolling up the slope net, the fixing nail is flush with the covering mesh cover, which is convenient for normal storage of the fixing nail, and the setting of the connecting ring ensures that the tip of the fixing nail can face the fixing hole when it is straightened again, ensuring the accurate position of the fixing nail when inserted, and the connecting ring will break during the hammering process.

[0011] Preferably, an inner groove is provided on the opposite side of the driving cart one and the driving cart two, and the top plate is located in the inner groove. A driving motor for driving the top plate to rotate is installed on the top of the driving cart two, and the bottom of the top plate is rotatably connected to a horizontally arranged trigger plate. When the driving cart two moves to the position of the fixed nail, the nail cap of the fixed nail will squeeze the trigger plate and rotate upward. A sensor is provided between the trigger plate and the top plate, which can monitor the rotation state of the trigger plate, so as to know that the driving cart two has moved above the fixed nail at this time, and then 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 fixed nail and rotate the fixed nail to a horizontal state, thereby realizing the accurate knowledge of the fixed nail position and the function of straightening the fixed nail. The top plate is foldable. When the fixed nail is straightened, the top plate bends and folds, so as not to hinder the work of the electric hammer to strike the fixed nail.

[0012] Preferably, a horizontally arranged slide groove is provided in the inner groove, an electric telescopic rod is fixed in the slide groove, and a fixed arm is fixed at the end of the electric telescopic rod. When the fixing nail is half-lifted by the top plate, the electric telescopic rod is started to push the fixed arm outward, and the two fixed arms are close to each other, fixing 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 be too tight with the fixing nail when straightening, so that the fixing nail can be normally combined with the slope under hammering.

[0013] Preferably, the top plate is arranged in sections, and the two sections of the top plate are rotatably connected by hinges, and a locking valve is installed between the ends of the two sections of the top plate. An electric winding roller is fixed to the top of the outer side of the top plate, and multiple steel cables are fixed to the outer side of the electric winding roller. The ends of the steel cables are fixed to the surface of the other section of the top plate. When the top plate half-lifts the fixing nail, the two fixed arms extend outward 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. In this way, the top plate will not hinder the electric hammer when it is rotated to the horizontal. When the electric hammer strikes multiple times, the fixed arms and the top plate are successively recovered and returned to their positions until the next straightening work.

[0014] Preferably, a tilted camera is fixedly connected to the outer side of the horizontal platform, the camera end of the camera faces downward, a spirit level is fixedly connected to the top of the horizontal platform, and a motor box for adjusting the horizontal platform is fixedly connected to the top of the driving vehicle one. The position of the fixing nail is observed through the camera to ensure that the electric hammer can correctly hammer the fixing nail. At the same time, the spirit 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, there is a height difference between the driving vehicle one and the driving vehicle two, which will cause the electric hammer to be not perpendicular to the fixing nail, which may easily cause problems in the hammering process. At this time, the motor box is started to drive the horizontal platform to rotate, so that the spirit level returns to its previous inclination; the inclination of the slope is often consistent, and it is adjusted when the data changes. It can also be adjusted according to the observation of the camera, so as to ensure that the electric hammer can stably hammer the fixing nail into the slope.

[0015] Preferably, the output end of the motor box is fixedly connected with a connecting block 1, the end of the connecting block 1 is fixedly connected to the horizontal platform, and the end of the horizontal platform and the driving vehicle 2 are fixedly connected with a connecting block 2. The connecting block 1 and the connecting block 2 are both made of elastic materials. Since it is difficult to ensure that the driving vehicle 1 and the driving vehicle 2 are completely synchronized, the horizontal platform is supported by the elastic connecting block 1 and the connecting block 2. In this way, when the driving vehicle 1 and the driving vehicle 2 are misaligned, the connecting block 1 and the connecting block 2 will be deformed, and can still stably support the horizontal platform, and the elastic support can be twisted in any direction to adapt to complex slope environments.

[0016] Preferably, the cap end of the fixing nail is fixed with a nail head plate, the middle part of the covering mesh is fixed with two binding ropes, a sleeve ring is fixed between the ends of the two binding ropes, the sleeve ring is fixed to the nail head plate, and the middle part of the fixing nail is fixed with multiple barb plates; the nail head plate is used to increase the force-bearing surface of the fixing nail, so that the top plate can flip the fixing nail upward, and the binding rope will restrain the fixing nail, so that the fixing nail can only move on one plane during the straightening process, and will not fall to the left and right, further ensuring that the fixing nail can be accurately nailed into the slope.

[0017] A mine slope repair method, the method specifically comprising:

[0018] S1: Throw the slope net downward from the top of the slope to cover the inclined slope, place the driving cart 1 and the driving cart 2 on two adjacent flexible slide rails, and install pulley clamps on the bottom of the driving cart 1 and the driving cart 2 to clamp on the flexible slide rails, so that the driving cart 1 and the driving cart 2 can move along the flexible slide rails;

[0019] S2: When the second driving vehicle moves to the position of the fixed nail, the nail cap of the fixed nail will squeeze the trigger plate to rotate upward, indicating that the second driving vehicle has moved above the fixed nail;

[0020] S3: After driving car 1 and driving car 2 move to the fixing nail, use the top plate and fixing arm to straighten the fixing nail from one side of the fixing nail, and then use the electric hammer, which can hit downward quickly and forcefully, so that the fixing nail passes through the covering net and is fixed to the slope. As driving car 1 and driving car 2 continue to move, all the fixing nails can be driven into the slope, thereby fixing the slope net on the slope.

[0021] The specific method for the top plate and the fixed arm in S to straighten the fixed nails is:

[0022] Q1: Start the drive motor to rotate the top plate, which presses against the surface of the nail cap to rotate the nail to a horizontal position. When the nail is half-lifted by the top plate, start the electric telescopic rod to push the fixing arm outward. The two fixing arms move closer to each other and fix the nail in the middle position.

[0023] Q2: When the top plate half-lifts the fixing nails, the two fixing arms extend outward to straighten the fixing nails. At the same time, the locking valve of the top plate is released, and the electric winding roller reels the steel cable to fold the top plate. In this way, the top plate will not interfere with the electric hammer when it rotates to the horizontal position.

[0024] The beneficial effects of the present invention are as follows:

[0025] 1. The mine slope repair device and method described in the present invention, through the arrangement of the covering mesh, the flexible slide rail, the driving vehicle one and the driving vehicle two, the driving vehicle one and the driving vehicle two can move along the flexible slide rail, and at the same time, the driving vehicle one and the driving vehicle two are started to move on the flexible slide rail. The movement mode can be from top to bottom or from bottom to top. Regardless of the movement mode, the driving vehicle one and the driving vehicle two will pull the slope net downward to further ensure that the slope net is laid flat on the slope. After the driving vehicle one and the driving vehicle two move to the fixed nail, the top plate is used to straighten the fixed nail from one side of the fixed nail, and then an electric hammer is used. The electric hammer can strike downward quickly and forcefully, and a cylinder structure or a hydraulic structure can be used; thereby, the fixed nail passes through the covering mesh. The cover is fixed to the slope, and as the driving vehicle one and the driving vehicle two 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 and reduce the damage and loss of the slope, but also the hanging slope net can facilitate the spraying of soil and plant seeds on the slope in the later stage, which can 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 achieved, but also multiple driving vehicles one and two can be placed at the same time for synchronous operation, thereby improving work efficiency. Moreover, since the fixing work is completed by machinery, the problem of various safety hazards that may occur easily due to the large inclination of the slope when manual work is carried out on the slope is greatly reduced.

The mine slope repair device and method described in the present invention fix the fixing nails directly on the covering mesh cover, which not only increases the weight of the slope mesh and makes it easier to unfold the slope mesh while rolling downward, but also the greater the gravity, the better the effect of unfolding and laying it flat on the slope. At the same time, during the nailing process of driving vehicle one and driving vehicle two, there is no need to carry the fixing nails themselves, and the fixing nails on the covering mesh cover can be directly straightened; the cap end of the fixing nail is bonded to the covering mesh cover by glue, and during the process of straightening the top plate, the adhesion will be broken, ensuring that the fixing nail can be straightened normally, and during the winding process of the slope mesh, the fixing nail is flush with the covering mesh cover, which is convenient for the normal storage of the fixing nail, and the setting of the connecting ring ensures that the tip of the fixing nail can face the fixing hole when it is straightened again, ensuring the accurate position of the fixing nail when inserted.

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0037] like Figures 1 to 7 As shown, a mine slope repair device according to an embodiment of the present invention includes a slope net 1, wherein the slope net 1 is composed of a plurality of flexible slide rails 6, adjacent flexible slide rails 6 are connected by a plurality of covering mesh covers 4, adjacent covering mesh covers 4 are connected end to end, and fixing nails 5 are provided on the top surface of the covering mesh covers 4. The device also includes a driving vehicle 2 and a driving vehicle 3, wherein a horizontal platform 15 is connected between the driving vehicle 2 and the driving vehicle 3, a vertical electric hammer 7 is installed in the middle of the horizontal platform 15, and a top plate 16 for straightening the fixing nails 5 is provided on the outer side of the driving vehicle 3;

[0038] The slope net 1 is initially in a rolled-up state. The slope net 1 is thrown downward from the top of the slope to cover the inclined slope. The slope net 1 needs to be pulled from the bottom and the top to ensure that the slope net 1 is laid flat on the slope. The spacing between adjacent slope nets 1 should not be too large. The slopes of mines are often hard, and although the slopes of mines are steep, the inclined surfaces are often flat. Uneven parts need to be flattened in advance. Place the driving vehicle 1 2 and the driving vehicle 2 3 on two adjacent On the flexible slide rail 6, the bottom of the driving car 1 2 and the driving car 2 3 are both installed with pulley clamps for clamping on the flexible slide rail 6, so that the driving car 1 2 and the driving car 2 3 can move along the flexible slide rail 6, and at the same time, the driving car 1 2 and the driving car 2 3 are started to move on the flexible slide rail 6. The movement mode can be from top to bottom or from bottom to top. No matter which movement mode, the driving car 1 2 and the driving car 2 3 will pull the slope net 1 downward to further ensure that the slope net 1 is laid flat on the slope. When the driving car 1 2 and After driving car 2 3 moves to fixing nail 5, top plate 16 is used to straighten fixing nail 5 from one side of fixing nail 5, and then electric hammer 7 is used, and electric hammer 7 can strike downward quickly and forcefully, and cylinder structure or hydraulic structure can be adopted; thereby fixing nail 5 is passed through covering mesh cover 4 and fixed to the side slope, and as driving car 1 2 and driving car 2 3 continue to move, all fixing nails 5 can be driven into the side slope, thereby fixing side slope net 1 on the side slope, after side slope net 1 is laid, not only can side slope soil be reinforced, and damage and loss of side slope be reduced, but also the hanging side slope net 1 can be convenient for spraying soil and plant seeds on side slope later, and side slope vegetation can be quickly restored to form ecological slope protection, which is both beautiful and environmentally friendly; through this arrangement, not only the work of fast fixing side slope net 1 is realized, but also multiple driving cars 1 2 and driving cars 2 3 can be placed at the same time for synchronous operation, thereby improving work efficiency; and because the fixing work is completed by machinery, the problem of various safety hazards easily occurring due to the large slope inclination when manual operation is carried out on the side slope is greatly reduced.

[0039] The surface of the cover mesh 4 is provided with a plurality of hollow holes, the middle portion of the cover mesh 4 is provided with a fixing hole 19, a connecting ring 20 is fixed between the tip of the fixing nail 5 and the cover mesh 4, and the cap end of the fixing nail 5 is bonded to the cover mesh 4;

[0040] When working, the fixing nail 5 is directly fixed on the covering mesh cover 4, which not only increases the weight of the slope net 1, but also makes the slope net 1 more convenient to unfold when it is unfolded and rolled down. The greater the gravity, the better the effect of paving the slope when it is unfolded. At the same time, in the process of nailing by driving vehicle 1 2 and driving vehicle 2 3, there is no need to carry the fixing nail 5 by themselves, and the fixing nail 5 on the covering mesh cover 4 can be directly straightened; the cap end of the fixing nail 5 is bonded to the covering mesh cover 4 by glue, and the adhesion will be broken during the straightening process of the top plate 16, ensuring that the fixing nail 5 can be normally straightened, and in the process of rolling up the slope net 1, the fixing nail 5 is flush with the covering mesh cover 4, which is convenient for the normal storage of the fixing nail 5, and the setting of the connecting ring 20 makes it possible for the tip of the fixing nail 5 to face the fixing hole 19 when it is straightened again, ensuring the accurate position of the fixing nail 5 when inserted, and the connecting ring 20 will break during the hammering process.

[0041] An inner groove 17 is formed on opposite sides of the driving vehicle 1 2 and the driving vehicle 2 3 . The top plate 16 is located in the inner groove 17 . A driving motor for rotating the top plate 16 is installed on the top of the driving vehicle 2 3 . The bottom of the top plate 16 is rotatably connected to a trigger plate 18 arranged horizontally.

[0042] During operation, 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 and rotate upward. 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 2 3 has moved to the top of the fixing nail 5 at this time, and then starting 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, and rotate the fixing nail 5 to a horizontal state, thereby realizing the accurate knowledge of the position of the fixing nail 5 and the function of straightening the fixing nail 5. The top plate 16 is foldable. When the fixing nail 5 is straightened, the top plate 16 bends and folds, so that it will not hinder the work of the electric hammer 7 to strike the fixing nail 5.

[0043] A horizontally arranged chute is provided in the inner groove 17, an electric telescopic rod is fixedly connected to the chute, and a fixed arm 13 is fixedly connected to the end of the electric telescopic rod;

[0044] 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 outward, and the two fixing arms 13 are close to each other, fixing 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 and does not need to be too tight with the fixing nail 5 when straightening, so that the fixing nail 5 can be normally combined with the slope under hammering.

[0045] The top plate 16 is provided in sections, and the two sections of the top plate 16 are rotatably connected by hinges. 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 top of the outer side of the top plate 16. A plurality of steel cables 24 are fixedly connected to the outer side of the electric winding roller. The ends of the steel cables 24 are fixedly connected to the surface of the other section of the top plate 16.

[0046] During operation, after the top plate 16 half-lifts 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 reels the steel cable 24 to fold the top plate 16. In this way, the top plate 16 will not hinder the electric hammer 7 when it is rotated to the horizontal position. After the electric hammer 7 has hammered several times, the fixing arms 13 and the top plate 16 are retracted and returned to their positions in turn, waiting for the next straightening work.

[0047] A tilted camera 10 is fixedly connected to the outside of the horizontal platform 15, with the camera end of the camera 10 facing downward. 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 2.

[0048] During operation, the position of the fixing nail 5 is observed through the camera 10 to ensure that the electric hammer 7 can hammer the fixing nail 5 correctly. At the same time, the spirit 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, there is a height difference between the driving vehicle 1 2 and the driving vehicle 2 3, which will cause the electric hammer 7 to be not perpendicular to the fixing nail 5, which may easily cause problems in the hammering process. At this time, the motor box 8 is started to drive the horizontal platform 15 to rotate, so that the spirit level 11 returns to the previous inclination; the inclination of the slope is often consistent, and it is adjusted when the data changes. It can also be adjusted according to the observation of the camera 10 to ensure that the electric hammer 7 can stably hammer the fixing nail 5 into the slope.

[0049] The output end of the motor box 8 is fixedly connected to a connecting block 19, the end of the connecting block 19 is fixedly connected to a horizontal platform 15, and the horizontal platform 15 and the end of the driving vehicle 2 3 are fixedly connected to a connecting block 2 12, and both the connecting block 19 and the connecting block 2 12 are made of elastic material;

[0050] During operation, since it is difficult to ensure that driving vehicle 1 2 and driving vehicle 2 3 are completely synchronized, the horizontal platform 15 is supported by elastic connecting blocks 1 9 and 2 12. In this way, when driving vehicle 1 2 and driving vehicle 2 3 are misaligned, connecting blocks 1 9 and 2 12 will deform and can still stably support the horizontal platform 15. The elastic support can be twisted in any direction to adapt to complex slope environments.

[0051] The cap end of the fixing nail 5 is fixed with a nail head plate 22, the middle part of the covering mesh 4 is fixed with two restraining ropes 21, the ends of the two restraining ropes 21 are fixed with a sleeve ring, the sleeve ring is fixed with the nail head plate 22, and the middle part of the fixing nail 5 is fixed with a plurality of barb plates 23;

[0052] During operation, the nail head plate 22 is used to increase the force-bearing surface of the fixing nail 5, which makes it easier for the top plate 16 to flip the fixing nail 5 upward, and the binding rope 21 binds the fixing nail 5 so that the fixing nail 5 can only move on one plane during the straightening process and will not fall to the left or right, further ensuring that the fixing nail 5 can be accurately nailed into the slope. A plurality of barbs are fixedly connected to the surface of the hook plate 23 to ensure that the fixing nail 5 can effectively grasp the soil after being inserted into the soil, thereby improving the fixing firmness of the fixing nail 5.

[0053] A mine slope repair method, the method specifically comprising:

[0054] S1: Throw the slope net 1 downward from the top of the slope to cover the inclined slope, place the driving vehicle 1 2 and the driving vehicle 2 3 on two adjacent flexible slide rails 6, and install pulley clamps on the bottom of the driving vehicle 1 2 and the driving vehicle 2 3 for clamping on the flexible slide rail 6, so that the driving vehicle 1 2 and the driving vehicle 2 3 can move along the flexible slide rail 6;

[0055] S2: When the driving vehicle 2 3 moves to the position of the fixing nail 5, the nail cap of the fixing nail 5 presses the trigger plate 18 to rotate upward, thereby indicating that the driving vehicle 2 3 has moved above the fixing nail 5;

[0056] S3: After driving car 1 2 and driving car 2 3 move to 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, and then use the electric hammer 7, which can hit downward quickly and forcefully, so that the fixing nail 5 passes through the covering net cover 4 and is fixed to the slope. As driving car 1 2 and driving car 2 3 continue to move, all the fixing nails 5 can be driven into the slope, thereby fixing the slope net 1 on the slope.

[0057] The specific method for the top plate 16 and the fixing arm 13 to straighten the fixing nail 5 in S3 is:

[0058] Q1: Start the drive motor to rotate the top plate 16. The rotation causes the top plate 16 to press against 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 move closer to each other and fix the fixing nail 5 in the middle position.

[0059] Q2: After the top plate 16 half-lifts 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 reels 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 a horizontal position.

[0060] During operation, the slope net 1 is initially in a rolled-up state. The slope net 1 is thrown downward from the top of the slope to cover the inclined slope. The slope net 1 needs to be pulled from the bottom and the top to ensure that the slope net 1 is laid flat on the slope. The spacing between adjacent slope nets 1 should not be too large. The slopes of mines are often hard, and although the slopes of mines are steep, the inclined surfaces are often flat. Uneven parts need to be flattened in advance. Place the driving vehicle 1 2 and the driving vehicle 2 3 on the two On the adjacent flexible slide rails 6, the bottom of the driving car 1 2 and the driving car 2 3 are both installed with pulley clamps for clamping on the flexible slide rails 6, so that the driving car 1 2 and the driving car 2 3 can move along the flexible slide rails 6, and at the same time, the driving car 1 2 and the driving car 2 3 are started to move on the flexible slide rails 6. The movement mode can be from top to bottom or from bottom to top. No matter which movement mode, the driving car 1 2 and the driving car 2 3 will pull the slope net 1 downward, further ensuring that the slope net 1 is laid flat on the slope. After the trolley 2 and the driving vehicle 2 3 move to the fixing nail 5, the top plate 16 is used to straighten the fixing nail 5 from one side of the fixing nail 5, and then the electric hammer 7 is used, which can quickly and forcefully strike downward, and a cylinder structure or a hydraulic structure can be used; thereby, the fixing nail 5 passes through the covering mesh cover 4 and is fixed to the slope, and as the driving vehicle 1 and the driving vehicle 2 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 and reduce the damage and loss of the slope, but also facilitate the spraying of soil and plant seeds on the slope in the later stage, and can quickly restore the slope vegetation to form an ecological slope protection, which is both beautiful and environmentally friendly; through this arrangement, not only the work of quickly fixing the slope net 1 is achieved, but also multiple driving vehicles 1 and driving vehicles 2 3 can be placed at the same time for synchronous operation, thereby improving work efficiency; and because the fixing work is completed by machinery, the problem of various safety hazards that may occur easily due to the large slope inclination when manual work is carried out on the slope is greatly reduced;

[0061] The fixing nail 5 is directly fixed on the covering mesh cover 4, which not only increases the weight of the slope net 1, but also makes the slope net 1 more convenient to unfold when it is unfolded and rolled down. The greater the gravity, the better the effect of paving the slope when it is unfolded. At the same time, in the process of nailing by driving vehicle 1 2 and driving vehicle 2 3, there is no need to carry the fixing nail 5 by themselves, and the fixing nail 5 on the covering mesh cover 4 can be directly straightened; the cap end of the fixing nail 5 is bonded to the covering mesh cover 4 by glue, and the adhesion will be broken during the straightening process of the top plate 16, so that the fixing nail 5 can be properly straightened, and in the process of rolling up the slope net 1, the fixing nail 5 is flush with the covering mesh cover 4, which is convenient for the normal storage of the fixing nail 5, and the setting of the connecting ring 20 makes it possible for the tip of the fixing nail 5 to face the fixing hole 19 when it is straightened again, so as to ensure the accurate position of the fixing nail 5 when inserted, and the connecting ring 20 will break during the hammering process;

[0062] 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 and rotate upward. 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, so as to know that the driving vehicle 2 3 has moved to the top of the fixing nail 5 at this time, and then 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, and rotate the fixing nail 5 to a horizontal state, thereby realizing the accurate knowledge of the position of the fixing nail 5 and the function of straightening the fixing nail 5. The top plate 16 is foldable. When the fixing nail 5 is straightened, the top plate 16 bends and folds, so as not to hinder the work of the electric hammer 7 to strike the fixing nail 5;

[0063] 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 outward, and the two fixing arms 13 are close to each other, fixing 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 and does not need to be too tight with the fixing nail 5 when straightening, so that the fixing nail 5 can be normally combined with the slope under hammering;

[0064] When the top plate 16 half-lifts 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 reels 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 has hammered several times, the fixing arms 13 and the top plate 16 are successively retracted and returned to their positions until the next straightening work.

[0065] The position of the fixing nail 5 is observed by the camera 10 to ensure that the electric hammer 7 can hammer the fixing nail 5 correctly. At the same time, the spirit 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, there is a height difference between the driving vehicle 1 2 and the driving vehicle 2 3, which will cause the electric hammer 7 to be not perpendicular to the fixing nail 5, which may easily cause problems in the hammering process. At this time, the motor box 8 is started to drive the horizontal platform 15 to rotate, so that the spirit level 11 returns to the previous inclination; the inclination of the slope is often consistent, and when the data changes, it is adjusted, or it can be adjusted according to the observation of the camera 10, so as to ensure that the electric hammer 7 can stably hammer the fixing nail 5 into the slope;

[0066] Since it is difficult to ensure that driving vehicle 1 2 and driving vehicle 2 3 are completely synchronized, the horizontal platform 15 is supported by elastic connecting blocks 1 9 and 2 12. In this way, when driving vehicle 1 2 and driving vehicle 2 3 are misaligned, connecting blocks 1 9 and 2 12 will deform and still stably support the horizontal platform 15. The elastic support can be twisted in any direction, thus adapting to complex slope environments.

[0067] The nail head plate 22 is used to increase the force-bearing surface of the fixing nail 5, which is convenient for the top plate 16 to flip the fixing nail 5 upward. The binding rope 21 binds the fixing nail 5 so that the fixing nail 5 can only move on one plane during the straightening process and will not fall to the left or right, further ensuring that the fixing nail 5 can be accurately nailed into the slope. A plurality of barbs are fixed on the surface of the hook plate 23 to ensure that the fixing nail 5 can effectively grasp the soil after being inserted into the soil, thereby improving the fixing firmness of the fixing nail 5.
