Description

Technical Field

[0001] The present invention relates to the technical field of slope treatment, and particularly to an open-pit mine slope reinforcement device with danger warning and a reinforcement method. Background Art

[0002] An open-pit mine strips the overlying soil and surrounding rock above and around the ore body, transports the waste rock to the waste dump, and directly extracts the ore from the exposed ore body. When the ore body is buried shallowly or outcrops on the surface, open-pit mining is superior to underground mining. With the exploitation of open-pit mines, the soft rock slopes of open-pit mines need to be artificially reinforced and maintained; Chinese Patent Publication No. CN219586756U discloses "an open-pit mine soft rock slope treatment and reinforcement device, including a bracket and a bolt. An adjustment and fixing component is installed on the side wall of the bracket. The adjustment and fixing component includes a plurality of fixing plates. The fixing plates slide on the lower side wall of the bracket. A connection port is opened on the surface of the fixing plate. The bolt passes through the connection port. The lower side wall of the bracket is rotatably connected with a protection plate through a shaft; in this utility model, the fixing plate can be adjusted according to the position of the bolt, reducing the requirement for distance accuracy during bolt installation. A threaded ring is installed above the bolt to prevent the bolt from detaching from the bracket and facilitating later disassembly. And the bracket is positioned by rotating the threaded telescopic rod to insert into the positioning groove to prevent the bracket from shaking." However, the above patent still has the following defects: For example, the state of the buffer structure cannot be monitored in real time. When the buffer structure is deformed or damaged due to slope deformation or impact, the lack of an alarm device means that these changes cannot be sensed in real time, resulting in managers being unable to judge in time whether the buffer structure has failed. And the deformation of the soft rock slope is often progressive, and the change in the force on the buffer structure may be a precursor to slope instability. Without an alarm device, manual inspections are required, which may delay the discovery of potential risks such as landslides and collapses.

[0003] Therefore, it is urgent to improve the reinforcement structure to solve the above problems. Summary of the Invention

A second gear meshes with the outside of the second rack; The loading shell includes a shell body, a drainage plate fixed inside the shell body, and a baffle plate rotating inside the shell body. The first transmission shaft extends into the loading shell and is fixed to one side of the baffle plate.

[0009] Preferably, the inside of the loading shell is hollowly arranged, and its bottom side is communicated with the outside.

[0014] Another technical problem to be solved by the present invention is to provide an open-pit mine slope reinforcement method with danger warning, comprising the following steps: S1. Active buffer reinforcement: A combination of rigid support and flexible buffer is formed through the L-shaped bottom plate, anchor rods and buffer parts such as buffer plates, buffer rods and buffer springs to disperse the slope stress; The buffer spring absorbs the deformation energy of the slope, and the buffer rod transmits the displacement to the driving mechanism; S2. Dynamic warning trigger: The deformation of the slope pushes the buffer plate and the buffer rod, and the displacement of the buffer rod abuts the driving mechanism to make it work, triggering the transportation of steel balls through mechanical transmission, and generating sound and light alarms through the magnetic structure and knocking structure.

[0015] The present invention has at least the following beneficial effects: 1. The present invention utilizes magnetic attraction to accelerate and trigger an early warning. When the steel ball is transferred from the inside of the loading shell into the conveying rack, it will be magnetically attracted and accelerated forward, enhancing the impact force under a great acceleration. The impact on the trigger plate triggers the early warning. By using the method of magnetic attraction acceleration, not only can the early warning mechanism be effectively triggered, but also the steel ball can obtain a large kinetic energy through the magnetic attraction effect, ensuring that a signal with sufficient intensity can be generated when the trigger plate is impacted, improving the accuracy and reliability of the early warning. The first gear drives the linkage gear through the synchronous pulley and synchronous belt, drives the lever to rotate the rotating sleeve, and makes the knocking ball periodically impact the loading shell, amplifying the mechanical alarm sound and further enhancing the effect of the acoustic early warning, ensuring that the early warning information can be clearly conveyed even in a noisy environment.

[0016] 2. The combined design of the collection pipe and the collection cover of the present invention can effectively collect the materials conveyed from the feeding structure. The outer shape of the collection cover is conical, which can expand the collection range, guide the scattered materials into the collection pipe, and improve the collection efficiency. A valve is rotatably installed inside the collection pipe. When the second gear rotates, it will drive the second transmission shaft and the valve to rotate, thereby changing the opening degree of the valve and adjusting the collection state, and the collection amount or collection speed of the materials can be flexibly controlled according to actual needs.

Detailed implementation manners

[0019] The technical solutions of the present invention will be further described in detail below in conjunction with the specific implementation manners.

[0020] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described by referring to the drawings below are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0021] As Figures 1 - 8As shown in the figure, the open-pit mine slope reinforcement device with danger warning provided in this embodiment includes a reinforcement structure 1 for the mine slope. The reinforcement structure 1 is composed of a bottom plate 101, a bolt 102 fixed on the bottom plate 101, and a buffer member arranged on one side of the bottom plate 101. The buffer member includes a buffer plate 103 arranged on one side of the bottom plate 101, a buffer rod 104 fixed on the side of the buffer plate 103 close to the bottom plate 101, and a buffer spring 105. The buffer rod 104 penetrates the inside of the bottom plate 101, and the other side of the buffer spring 105 is fixed to the outer surface of the bottom plate 101. The number of bottom plates 101 is L-shaped. When the slope undergoes displacement or landslide, the buffer plate 103 is impacted, pushing the buffer rod 104 to move into the inside of the bottom plate 101 and compressing the buffer spring 105. This buffer mechanism can effectively absorb and disperse the impact energy, prevent the device from being damaged due to directly bearing huge impact force, extend the service life of the equipment, and reduce the maintenance cost.

[0022] To achieve slope reinforcement warning, a driving mechanism 2 and a warning mechanism 3 that cooperate with each other are arranged on the bottom plate 101. The driving mechanism 2 uses the impact of the buffer member to drive the warning mechanism 3. The driving mechanism 2 includes a contact plate 201, two sliding seats 202 distributed vertically, a transmission structure 205 and a driving structure respectively arranged on the two sliding seats 202. Specifically, the warning mechanism 3 includes a loading shell 301 arranged above the bottom plate 101, a conveying frame 302, a magnetic structure 303 and a trigger plate 305 arranged on the conveying frame 302. The magnetic structure 303 includes a magnetic block 3031 slidably arranged on the conveying frame 302 and an electric telescopic rod 3032 fixed on the outer surface of the conveying frame 302. A feeding structure 304 and a collecting structure 307 are arranged on the lower surface of the conveying frame 302. Steel balls are arranged on the feeding structure 304, the conveying frame 302 and the loading shell 301. A knocking structure 309 that cooperates with the transmission structure 205 is arranged outside the loading shell 301. The transmission structure 205 and the driving structure are respectively used to drive the feeding structure 304 and the collecting structure 307.

[0023] In this embodiment, two first push arms 204 are hinged between the abutting plate 201 and the two sliding seats 202. The abutting plate 201 is displaced by the abutment of the buffer rod 104, and the two sliding seats 202 are driven to move relatively by the first push arms 204. The sliding seats 202 distributed vertically and horizontally achieve relative movement through the first push arms 204, decomposing the impact force of the slope displacement into bidirectional mechanical drive to ensure that displacements in different directions can trigger early warnings. Limiting brackets 211 are welded on the outer surfaces of the loading shell 301 and the conveying frame 302, and a limiting structure 203 for limiting the two sliding seats 202 is fixed between the two limiting brackets 211. The limiting structure 203 includes a guide rod fixed to the brackets of the two limiting brackets 211 and a protection spring fixed to the opposite sides of the two limiting brackets 211. The opposite ends of the two protection springs are respectively fixed to the upper and lower sides of the two sliding seats 202, and the two protection springs are both wound around the outside of the guide rod. The combination of the guide rod and the protection spring provides guidance and elastic reset when the sliding seat 202 moves, avoiding mechanical overload damage, and at the same time adjusting the trigger threshold through the spring pre-tightening force to adapt to different geological conditions.

[0024] In this embodiment, the transmission structure 205 includes a first rack 2053 fixed to the outer surface of the top sliding seat 202, a first gear 2052 meshing with the outside of the first rack 2053, and a first transmission shaft 2051 fixed to the outer surface of the first gear 2052. The first transmission shaft 2051 extends into the loading shell 301. The driving structure includes a locking rod 206 reciprocatingly arranged on the bottom limiting bracket 211 and a second push arm 207 hinged between one end of the limiting bracket 211 and the bottom sliding seat 202. A connecting rod 208 is fixed to the outer surface of the end of the locking rod 206 away from the bottom sliding seat 202, and a second rack 209 is fixed to the other end of the connecting rod 208. A second gear 210 meshes with the outside of the second rack 209. To achieve the loading of steel balls, the loading shell 301 includes a shell body 3011, a drainage plate 3012 fixed to the inner side of the shell body 3011, and a baffle plate 3013 rotating inside the shell body 3011. The first transmission shaft 2051 extends into the loading shell 301 and is fixed to one side of the baffle plate 3013. The first rack 2053 is fixed to the outer surface of the top sliding seat 202. When the top sliding seat 202 moves, the first rack 2053 moves accordingly, driving the meshing first gear 2052 to rotate. The first transmission shaft 2051 is fixed to the first gear 2052, and its rotation will drive the baffle plate 3013 in the loading shell 301 to rotate, controlling the angle of the baffle plate 3013, thereby changing the flow path of the steel balls in the loading shell 301; Moreover, the locking lever 206 is reciprocally arranged on the bottom limit bracket 211 and is connected to the bottom slide 202 through the second push arm 207. When the bottom slide 202 moves, it will drive the second push arm 207 to move, and then make the locking lever 206 move. The connecting rod 208 and the second rack 209 on the locking lever 206 move accordingly, driving the second gear 210 to rotate. This linkage mechanism can convert the movement of the bottom slide 202 into the rotational movement of the second gear 210, realizing the coordinated work between different components.

[0025] Specifically, the inside of the loading shell 301 is hollow and its bottom side is in communication with the outside. The loading shell 301 is fixed to the outer surface of the right end of the conveying rack 302. The conveying rack 302 consists of two parts. One part of the conveying rack 302 is horizontally arranged, and the other part of the conveying rack 302 is inclined. The output end of the electric telescopic rod 3032 is fixed to the outer surface of the magnet block 3031, and a perforation adapted to the steel ball is opened inside the magnet block 3031. The installation of the electric telescopic rod 3032 can lift the magnet block 3031 after the equipment is used. At this time, the steel ball can pass through the perforation and enter the other side of the magnet block 3031, and then put down the magnet block 3031 to attract and fix the steel ball by the magnetic force of the magnet block 3031. After being attracted by the magnet block 3031, the steel ball hits the trigger plate 305 at a high speed, and even a tiny slope displacement can generate sufficient impact force, solving the problem of hysteresis in the response of the traditional mechanical system. It should be noted that a shielding cover can be arranged outside the warning mechanism 3 to reduce the erosion of impurities or rainwater. The structure of this application has been subjected to anti-corrosion treatment.

[0026] In this embodiment, the material feeding structure 304 includes a material feeding cylinder 3041 bolted to the lower surface of the conveying frame 302, a push block 3042 reciprocatingly arranged inside the material feeding cylinder 3041, a return spring 3043 and a pull rod 3044 fixed to the lower surface of the push block 3042. The bottom side of the return spring 3043 is fixed to the inner bottom wall of the material feeding cylinder 3041. The pull rod 3044 penetrates through the inside of the material feeding cylinder 3041. One end of the locking rod 206 away from the sliding seat 202 extends into the material feeding cylinder 3041 and is inserted into the push block 3042. The locking rod 206 triggers the push block 3042. When the slope displacement pushes the sliding seat 202, the locking rod 206 disengages from the material feeding cylinder 3041. At this time, the push block 3042 pushes the steel balls upward to the conveying frame 302. After the impact, the push block 3042 is pulled back through the pull rod 3044 to prepare for the next transportation, realizing self-circulating feeding. It should be noted that the left side of the conveying frame 302 is open. An installation rod 306 connected to the trigger plate 305 is provided on the outer surface of the left side of the conveying frame 302. A material guiding table 308 for guiding materials is fixed to the outer surface of the trigger plate 305. The material guiding table 308 cooperates with the collection structure 307. The material guiding table 308 attached to the trigger plate 305 guides the steel balls after impact to the collection pipe 3071, preventing the steel balls from scattering and ensuring the closure of the circulation system. Specifically, the collection structure 307 includes a collection pipe 3071 fixed to the outer surface of the material feeding cylinder 3041 and a collection cover 3072 fixed to the other end of the collection pipe 3071. The outer shape of the collection cover 3072 is conical. A valve 3073 is rotatably installed inside the collection pipe 3071. A second transmission shaft 3074 fixed to the second gear 210 is fixed to the side wall of the valve 3073. Drainage holes are provided in the collection pipe 3071. When this embodiment is in use, the combined design of the collection pipe 3071 and the collection cover 3072 can effectively collect the materials conveyed from the material feeding structure 304. The outer shape of the collection cover 3072 is conical, which can expand the collection range, guide the scattered materials into the collection pipe 3071, and improve the collection efficiency. A valve 3073 is rotatably installed inside the collection pipe 3071. When the second gear 210 rotates, it will drive the second transmission shaft 3074 and the valve 3073 to rotate, thereby changing the opening degree of the valve 3073 and adjusting the collection state. The collection amount or collection speed of the materials can be flexibly controlled according to actual needs.

[0027] It should be noted that when the locking rod 206 is working, the feeding structure 304 is feeding, and at this time, the collecting structure 307 is blocked under the action of the driving structure. When the feeding structure 304 is feeding, it cooperates with the unloading of the loading shell 301 to realize the conveying of the steel balls. The feeding channel of the shell 3011 can also be set to the state of placing a single steel ball, that is, the steel ball is placed vertically and individually, which can avoid the situation that the steel ball is stuck. After the feeding structure 304 is finished working, the push block 3042 is moved down by the pull rod 3044, and the locking rod 206 locks the feeding structure 304. At this time, the valve 3073 of the collecting structure 307 is opened, and the steel balls in the collecting tube 3071 are conveyed to the feeding cylinder 3041.

[0028] To further improve the warning effect, the knocking structure 309 includes an installation shaft 3091 fixed to the outside of the shell 3011, a rotating sleeve 3092 rotating on the outer surface of the installation shaft 3091, a linkage gear 3096 rotatably installed on the outside of the shell 3011, a connecting rod 3093 threadedly installed inside the rotating sleeve 3092, and a knocking ball 3094 welded to the other end of the connecting rod 3093 and abutting against the outer surface of the shell 3011. A lever 3095 abutting against the linkage gear 3096 is slidably installed on the lower surface of the rotating sleeve 3092. The connecting rod 3093 is threadedly adjusted to fine-tune the contact distance between the knocking ball 3094 and the loading shell 301, thereby controlling the impact force and avoiding loosening or excessive wear caused by long-term vibration. A synchronous wheel 3097 is fixed between the linkage gear 3096 and the first gear 2052, and a synchronous belt 3098 is connected between the two synchronous wheels 3097. The linkage gear 3096 is connected to the first gear 2052 through the synchronous wheel 3097 and the synchronous belt 3098. When the first gear 2052 rotates with the movement of the top slide 202, the linkage gear 3096 is driven to rotate synchronously. When the linkage gear 3096 rotates, the lever 3095 on it will drive the rotating sleeve 3092 to rotate, thereby causing the connecting rod 3093 to drive the knocking ball 3094 to perform periodic movement, thereby achieving periodic knocking of the housing 3011. This periodic knocking can continuously generate a mechanical alarm sound, thereby enhancing the early warning effect.

[0029] In addition, the knocking work of the knocking ball 3094 can generate certain vibrations on the housing 3011, thereby better performing the conveying work. The slidingly mounted lever 3095 also facilitates the reset of the subsequent structure.

[0030] Another technical problem to be solved by the present invention is to provide an open-pit mine slope reinforcement method with danger warning, comprising the following steps: S1. Active buffer reinforcement: A combination of rigid support and flexible buffer is formed by the L-shaped bottom plate 101, anchor rods 102 and buffer members such as buffer plates 103, buffer rods 104 and buffer springs 105 to disperse the slope stress; The buffer spring 105 absorbs the deformation energy of the slope, and the buffer rod 104 transmits the displacement to the driving mechanism 2; S2. Dynamic warning trigger: The deformation of the slope pushes the buffer plate 103 and the buffer rod 104 , and the buffer rod 104 moves to abut against the driving mechanism 2 to make it work, triggering the transportation of the steel ball through mechanical transmission, and generating sound and light alarms through the magnetic structure 303 and the knocking structure 309 .

[0031] like Figures 1 - 8 As shown, the principle of the open-pit mine slope reinforcement device with danger warning provided by this embodiment is as follows: When the slope is displaced or landslides, the buffer plate 103 is impacted, pushing the buffer rod 104 to move toward the inside of the bottom plate 101, compressing the buffer spring 105. The movement of the buffer rod 104 causes the abutment plate 201 to be displaced, and the two slide seats 202 are driven to move relative to each other through the first push arm 204. The movement of the top slide 202 moves the first rack 2053, driving the first gear 2052 and the first transmission shaft 2051 to rotate. The rotation of the first transmission shaft 2051 causes the baffle 3013 to rotate in the loading shell 301, changing the flow path of the steel balls. The movement of the bottom slide 202 causes the locking rod 206 to move, which drives the second rack 209 to move through the connecting rod 208, thereby causing the second gear 210 and the second transmission shaft 3074 to rotate. The rotation of the second transmission shaft 3074 causes the valve 3073 to rotate in the collection pipe 3071, thereby changing the collection state. When the steel ball is transferred from the loading shell 301 to the conveying rack 302, the steel ball is attracted by the magnetism and accelerates forward. At this time, the steel ball contacts the magnetic block 3031, and the impact force is enhanced under the great acceleration, generating thrust, so that the steel ball on the other side of the magnetic block 3031 on the conveying rack 302 moves quickly, and hits the trigger plate 305. When the steel ball collides with the trigger plate 305, vibration noise is generated to form an acoustic warning, and the displacement of the magnetic block 3031 can link the external Hall element electronic sensor to generate a photoelectric alarm signal; In addition, the first gear 2052 drives the linkage gear 3096 through the synchronous wheel 3097 and the synchronous belt 3098, and drives the rotating sleeve 3092 to rotate through the lever 3095, so that the knocking ball 3094 periodically hits the shell 3011, amplifying the mechanical alarm sound.

[0032] As used in the specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in names as a way to distinguish components, but rather use the difference in the functions of the components as the criterion for distinction. As used throughout the specification and claims, "comprising" is an open-ended term and should be interpreted as "including but not limited to". "Substantially" means within an acceptable error range. Those skilled in the art can solve technical problems within a certain error range and basically achieve the technical effect.
