Description

Technical Field

[0001] This application relates to the technical field of mine safety protection, and in particular to a recyclable covering net for use in mines. Background Technology

[0002] Mining activities cause multifaceted environmental damage. In open-pit mines, ore piles and waste heaps are left exposed, easily generating dust under wind erosion. This not only pollutes the surrounding atmosphere and affects air quality but also harms the health of nearby residents. Simultaneously, rainwater runoff can cause harmful substances from ore and waste to seep into soil and water bodies, leading to soil and water pollution. Furthermore, exposed slopes created by mining are prone to soil erosion and rock weathering, potentially triggering landslides and other geological disasters. To mitigate these environmental problems, it is necessary to use covering nets to protect relevant mining areas. Covering nets effectively prevent material scattering, reduce dust pollution, slow down weathering, and also mitigate soil erosion and rockfall hazards to some extent.

[0003] A search revealed Chinese patent publication number CN118959067A, which discloses a recyclable covering net for open-pit mines, comprising a covering net, a rope, and connectors. Multiple connectors are provided on both sides of the covering net, with multiple connectors on one side fitted onto the rope. The connectors are used to lock the rope, and adjacent connectors are detachably connected. Compared to existing technologies, this invention uses the rope to fix the covering net to the ore pile, making the covering net application convenient and quick. The covering net can be recycled multiple times simply by using the rope, reducing operating costs and improving economic efficiency. The maximum unfolded width of the covering net can be adjusted to adapt to different shapes and sizes of ore piles.

[0004] Although the aforementioned patents have solved the problem of poor stability during the use of the cover net, manual fixing is still required during installation, and the installation device used has poor support stability. It is prone to shaking or even tilting during the installation and uninstallation of the cover net, which not only affects the efficiency of net roll installation and uninstallation, but also poses safety hazards due to structural instability. In addition, the excessive friction between the installation and uninstallation device and the net roll will cause severe wear on the surface of the net roll due to frequent installation and uninstallation operations, shortening the service life of the cover net. At the same time, the excessive friction will significantly increase the energy consumption of the equipment and increase the operating costs of the mine. Utility Model Content

[0005] The purpose of this application is to provide a recyclable covering net for mining, which aims to improve the problems of unstable support of the installation pole, which affects the efficiency and safety of net roll winding and unwinding, as well as the serious wear of net rolls, increased equipment energy consumption, and jamming and unsmooth winding and unwinding operations caused by excessive friction.

[0006] This application provides a recyclable covering net for mines, employing the following technical solution: A recyclable covering net for mines includes a net roll, the net roll having an internal winding and unwinding mechanism, and the other end of the net roll having a laying mechanism. The winding and unwinding mechanism includes an installation rod, the installation rod being externally supported inside the net roll, a locking post being fixedly connected to the outside of the installation rod, and support frames being rotatably connected to both ends of the installation rod. A support plate is fixedly connected to the bottom of the support frame, an extension rod is fixedly connected to the outside of the support frame, a fixing rod is fixedly connected to the outside of the support plate, a protective frame is fixedly connected to the outside of the support plate, an adjusting roller is rotatably connected to the other end of the support frame, a docking wheel is rotatably connected inside the support plate, a transmission component is fixedly connected to the outside of the docking wheel, a drive component is fixedly connected to the outside of the docking wheel, and a moving component is fixedly connected to the outside of the extension rod.

[0007] Through the above technical solution: the drive component drives the docking wheel to rotate, and the docking wheel transmits power through the transmission component, enabling the net roll to be unwound and retracted on the mounting rod. The locking post plays a role in positioning the net roll and preventing it from shifting during unwound and retracted operations. The support frame provides stable support in conjunction with the support plate through a rotating connection. The extension rod increases the stability and adaptability of the overall structure. The protective frame protects the internal structure from the harsh environment of the mine. The adjusting roller can adjust the cover net to make its laying more flat. The moving component is installed on the extension rod to facilitate the movement of the entire cover net device in different locations in the mine. The laying mechanism is responsible for unfolding and laying the cover net in the net roll.

[0008] Preferably, the laying mechanism includes a connecting rod, the connecting rod is fixedly connected to the other end of the net roll, a main shaft is fixedly connected to both sides of the connecting rod, a pull rod is fixedly connected to the outside of the main shaft, hooks are rotatably connected to both sides of the pull rod, a support wheel is rotatably connected to the outside of the main shaft, and an adjusting plate is rotatably connected to the outside of the support wheel.

[0009] By adopting the above technical solution, when the net roll is unrolled by the winding mechanism, the laying mechanism operates accordingly. The connecting rod serves as the connecting base, driving the main shaft to move synchronously. The pull rod on the main shaft moves accordingly, and the hooks on both sides can rotate flexibly. During the laying process, it can connect to other power sources, so that the net roll maintains stable tension during laying, preventing the net surface from loosening or shifting. The support wheels outside the main shaft roll on the ground, providing support for the laying process, reducing friction, and making the laying smoother. The adjustment plate connected to the outside of the support wheels can be adjusted at an angle according to the terrain or laying requirements, further optimizing the laying effect and ensuring that the net roll can cover the mine surface flat.

[0010] Preferably, a support roller is rotatably connected to the other end of the main shaft, and a backing plate is fixedly connected to the other end of the main shaft. An adjusting bolt is threadedly connected to the more distant side of the backing plate.

[0011] By adopting the above technical solution, when the laying mechanism unfolds the cover net with the net roll, the support roller at the other end of the main shaft rolls on the ground, which further enhances the stability of the laying process, reduces resistance, and makes the laying of the cover net smoother. The abutment plate is fixed on the main shaft, and the distance between the abutment plate and the ground or other support surfaces can be adjusted by rotating the adjusting bolt, thereby adjusting the height and pressure of the support roller.

[0012] Preferably, the adjusting plate is internally slidably connected to the inner outer side of the abutment plate, and the other end of the adjusting bolt is supported inside the adjusting plate;

[0013] By adopting the above technical solution, when the adjusting bolt is rotated, its other end applies a force to the adjusting plate. Since the adjusting plate can slide inside and outside the backing plate, the position of the adjusting plate can be precisely changed by rotating the adjusting bolt in or out.

[0014] Preferably, the movable component includes a rotating shaft, the outside of which is fixedly connected to the inside of the extension rod, and movable wheels are rotatably connected to both sides of the outside of the rotating shaft, and casters are fixedly connected to the bottom of the support plate;

[0015] By adopting the above technical solution, the mobile component assists the covering net device in moving in the mine. The rotating shaft is fixed to the extension rod, and the moving wheels on both sides can rotate flexibly. On the relatively flat ground of the mine, the moving wheels provide the main moving power, which makes it convenient for the device to move in a straight line or a specific direction. The universal wheels at the bottom of the support plate, with their 360-degree rotation characteristics, make the device more flexible and free when turning and fine-tuning its position.

[0016] Preferably, the transmission assembly includes a secondary gear, the secondary gear being internally fixedly connected to the outer side of the mating wheel, a main gear being fixedly connected to the outer side of the mounting rod, and a follower gear being fixedly connected to the outer side of the adjusting roller.

[0017] By adopting the above technical solution, the drive component drives the docking wheel to rotate, and the secondary gear on the docking wheel rotates accordingly. The secondary gear is transmitted to the main gear through the drive component, which transmits power to the mounting rod, so that the net roll on the mounting rod can realize the winding and unwinding action. At the same time, the secondary gear also drives the adjusting roller to rotate through the meshing of the drive component.

[0018] Preferably, the drive assembly includes a control motor, the output end of which is fixedly connected to the outer side of the docking wheel, the outer side of the control motor is fixedly connected to the outer side of a protective frame, a drive belt is slidably connected inside the protective frame, the drive belt is internally meshed with the outer side of the follower gear, the drive belt is internally meshed with the outer side of the main gear, and the drive belt is internally meshed with the outer side of the follower gear.

[0019] By adopting the above technical solution, the control motor starts, and its output end drives the docking wheel to rotate. The docking wheel transmits power to the drive belt through the secondary gear, which drives the main gear and the follower gear, so that the net roll and the adjusting roller on the mounting rod rotate synchronously, realizing the winding and unwinding of the cover net. The protective frame provides protection for the control motor and drive belt, avoiding damage to them from dust, gravel and other objects in the mining environment.

[0020] Preferably, the inside of the wire mesh roll is fixedly connected with multiple extension strips, and both sides of the inside of the wire mesh roll are fixedly connected with reinforcing strips;

[0021] By adopting the above technical solution, when the winding mechanism drives the net roll to unfold or wind up the cover net, the multiple extension bands inside the net roll can adaptively extend or contract with the rotation of the net roll, so that the cover net maintains uniform tension during the laying process, avoids damage or wrinkles caused by uneven local stress, and ensures the flatness and integrity of the cover net laying. At the same time, the reinforcing bands on both sides inside the net roll enhance the structural strength of the cover net edge, prevent the edge from being damaged by friction or pulling during the winding and unwinding process, and extend the service life of the cover net.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. In this utility model, the support frame and support plate work together to stably fix the mounting rod, facilitating the winding and unwinding of the net roll. The protective frame protects the drive and transmission components. The coupling wheel and adjusting roller work together with the mounting rod to reduce the friction between the net roll and the device when the net roll rotates. This solves the problems of unstable mounting rod support, which affects the winding and unwinding efficiency and safety of the net roll, and the problems of excessive friction causing severe wear of the net roll, increased energy consumption of the equipment, and jamming and unsmooth winding and unwinding operations.

[0024] 2. In this utility model, the external force pulls the pull rod through the hook lock connection, which in turn pulls the net roll and drives the main shaft to unfold the net roll. At the same time, the external support wheel and support roller share the weight of the covering net. The adjustment plate, together with the adjustment bolt and the abutment plate, adjusts the tilt angle and height of the support wheel, thereby achieving the effect of the covering net closely conforming to different terrains and completing the stable laying effect.

[0030] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0031] Example: A recyclable covering net for mines, see reference. Figures 1 to 3 The system includes a net roll 1, which is a covering net. The net roll 1 is wound up to facilitate transportation, storage and use. The net roll 1 is equipped with a winding and unwinding mechanism 2. The other end of the net roll 1 is equipped with a laying mechanism 8. Multiple extension strips 6 are fixedly connected inside the net roll 1. The extension strips 6 increase the extensibility and flexibility of the covering net, so that the covering net can better adapt to the undulating changes of the complex terrain of the mine. Reinforcing strips 7 are fixedly connected on both sides inside the net roll 1. The reinforcing strips 7 enhance the overall strength and durability of the covering net.

[0032] The winding and unwinding mechanism 2 includes a mounting rod 21, which provides central support for the net roll 1, ensuring its stability during rotation. The external support of the mounting rod 21 is located inside the net roll 1. A locking post 22 is fixedly connected to the outside of the mounting rod 21, restricting the axial displacement of the net roll 1 on the mounting rod 21 to prevent it from shifting during rotation and ensuring stability during winding and unwinding. Support frames 23 are rotatably connected to both ends of the mounting rod 21, supporting the mounting rod 21 and transferring the weight of the net roll 1 and the covering net to the support plate 25. The support plate 25 is fixedly connected to the bottom of the support frame 23, serving as the bottom support structure of the winding and unwinding mechanism 2 and bearing the weight of the entire mechanism and the net roll 1. An extension rod 24 is fixedly connected to the outside of the support frame 23. The extension rod 24 connects the support frame 23 and the moving component 3, increasing the lateral support range of the cover net winding and unwinding mechanism 2. The support plate 25 is externally fixedly connected to a fixing rod 26, which is used to connect the extension rod 24 and the support plate 25. The support plate 25 is externally fixedly connected to a protective frame 29, which protects the drive component 5 and the transmission component 4. The other end of the support frame 23 is rotatably connected to an adjusting roller 28, which adjusts the conveying angle of the net roll 1. The support plate 25 is internally rotatably connected to a docking wheel 27, which transmits the power of the control motor 52 to the transmission component 4, thereby driving the net roll 1 to rotate. The docking wheel 27 is externally fixedly connected to the transmission component 4 and the drive component 5. The extension rod 24 is externally fixedly connected to the moving component 3.

[0033] Specifically, to achieve convenient deployment and stable laying of the mine cover net, the device uses a net roll 1 as the main body, with a deployment mechanism 2 embedded inside and a laying mechanism 8 at the other end. The net roll 1 has multiple extension strips 6 and two side reinforcement strips 7. The former improves the extensibility and flexibility of the cover net to adapt to complex mine terrain, while the latter enhances the overall strength. In the deployment mechanism 2, the mounting rod 21 serves as the central support of the net roll 1 to ensure rotational stability, the locking post 22 restricts the axial displacement of the net roll 1 to prevent it from shifting, the support frame 23 is connected to the support plate 25 at the bottom to transfer the weight downwards, the extension rod 24 on its outside expands the lateral support range, the fixing rod 26 securely connects the extension rod 24 and the support plate 25, the protective frame 29 protects the drive component 5 and the transmission component 4, the adjusting roller 28 can adjust the conveying angle of the net roll 1, and the docking wheel 27 transmits the power of the control motor 52 to the transmission component 4 to drive the net roll 1 to rotate. The moving component 3 on the extension rod 24 facilitates the movement of the entire device, achieving efficient deployment and laying.

[0034] The moving component 3 includes a rotating shaft 31, which is the rotating shaft of the moving wheel 32, providing support and rotation center for the moving wheel 32. The external of the rotating shaft 31 is fixedly connected to the inside of the extension rod 24. The moving wheels 32 are rotatably connected to the external sides of the rotating shaft 31. The moving wheels 32 are in direct contact with the ground and move the deployment and take-up mechanism 2 by rolling, so that the covering net can be quickly transferred to different working areas in the mine, improving work efficiency. The bottom of the support plate 25 is fixedly connected to a universal wheel 33, which further enhances the mobility of the deployment and take-up mechanism 2, enabling the equipment to move in any direction in narrow spaces or complex terrain.

[0035] The transmission assembly 4 includes a secondary gear 43, which is used to transmit power to the docking wheel 27. The internal part of the secondary gear 43 is fixedly connected to the external side of the docking wheel 27. The external side of the mounting rod 21 is fixedly connected to the main gear 41. The main gear 41 converts the rotational force brought by the drive belt 51 into the rotational power of the net roll 1, which drives the net roll 1 to wind up and unwind the covering net. The external side of the adjusting roller 28 is fixedly connected to the follower gear 42. The follower gear 42 is fixedly connected to the adjusting roller 28 and receives the power transmitted by the drive belt 51.

[0036] The drive assembly 5 includes a control motor 52, which serves as the power source for the netting system, providing power for the net roll 1. By controlling the forward and reverse rotation and speed adjustment of the control motor 52, the netting can be laid and retrieved. The output end of the control motor 52 is fixedly connected to the outside of the docking wheel 27. The outside of the control motor 52 is fixedly connected to the outside of the protective frame 29. The inside of the protective frame 29 is slidably connected to the drive belt 51. The drive belt 51 connects the main gear 41, the follower gear 42, and the auxiliary gear 43. Through meshing with the gears, the power of the control motor 52 is transmitted to the net roll 1, realizing long-distance power transmission and distribution. The inside of the drive belt 51 is meshed with the outside of the follower gear 42, the outside of the main gear 41, and the outside of the follower gear 42.

[0037] Specifically, to meet the needs of mining operations, the moving component 3, the transmission component 4, and the drive component 5 work together. In the moving component 3, the rotating shaft 31 is fixed inside the extension rod 24, providing rotational support for the moving wheels 32 on both sides, enabling them to quickly transfer the take-up and release mechanism 2 to different working areas through rolling. The universal wheels 33 at the bottom of the support plate 25 give the equipment the ability to turn flexibly in narrow spaces or complex terrain. In the transmission component 4, the secondary gear 43 is fixed to the docking wheel 27. After receiving power, it is transmitted to the main gear 41 and the follower gear 42 through the drive belt 51. The main gear 41 drives the mounting rod 21 to rotate to realize the take-up and release of the net roll 1. The follower gear 42 synchronously adjusts the roller 28 to work together. The drive component 5 uses the control motor 52 as the core power source. Its output end is connected to the docking wheel 27. It precisely controls the laying and retrieval of the cover net through forward and reverse rotation and speed adjustment. The drive belt 51 in the protective frame 29 achieves efficient power distribution and long-distance transmission through meshing with the gear set, ensuring the stable operation of the entire take-up and release system.

[0038] Reference Figure 1 , Figure 2 and Figure 4 The laying mechanism 8 includes a connecting rod 81, which transmits the force of the net roll 1 to the laying mechanism 8. The connecting rod 81 is fixedly connected to the other end of the net roll 1. The main shaft 82 is fixedly connected to both sides of the connecting rod 81. The main shaft 82 provides the central shaft for installation and rotation. The pull rod 83 is fixedly connected to the outside of the main shaft 82. During the laying of the cover net, the net roll 1 is unfolded by pulling the pull rod 83. Hook locks 84 are rotatably connected to both sides of the pull rod 83. The hook locks 84 are used to connect the pull rod 83 to external force, so as to fix the cover net on the mine ground. The main shaft 82 is rotatably connected to the outside of the main shaft 82. The support wheel 85 supports the cover net during the laying process, reduces the friction between the cover net and the ground, reduces the wear of the cover net, and at the same time assists in guiding the laying direction of the cover net to ensure that the cover net is laid flat.

[0039] An adjusting plate 86 is rotatably connected to the outside of the support wheel 85. The adjusting plate 86 cooperates with the support wheel 85 and changes the tilt angle and height of the support wheel 85 by adjusting its own position to adapt to the needs of laying the cover net under different terrain conditions and ensure that the cover net is tightly attached to the ground. The other end of the main shaft 82 is rotatably connected to a support roller 87, which further assists in supporting the cover net and shares the weight of the cover net during the laying process. The other end of the main shaft 82 is fixedly connected to a back plate 88, which provides an installation and support base for the adjusting plate 86 and the adjusting bolt 89. The adjusting bolt 89 is threadedly connected to the far side of the back plate 88. The adjusting bolt 89 loosens or tightens the back plate 88 by rotating, which causes the adjusting plate 86 to move and thus changes the state of the support wheel 85. The inside of the adjusting plate 86 is slidably connected to the inside and outside of the back plate 88, and the other end of the adjusting bolt 89 is supported inside the adjusting plate 86.

[0040] Specifically, the laying mechanism 8 achieves efficient laying of the cover net on the mine ground through the coordinated operation of multiple components. The connecting rod 81 connects the net roll 1 to the laying mechanism 8 and undertakes the force transmission function. The two main shafts 82 serve as the core rotating shafts 31, and the tie rods 83 fixed on them can be pulled by external force to unfold the net roll 1. The hooks 84 at both ends of the tie rods 83 facilitate the connection of external traction devices to fix the cover net to the ground. During the laying process, the support wheel 85 rotates around the main shaft 82 to support the cover net and reduce its friction with the ground, reducing wear and assisting in guiding the laying direction. The adjusting plate 86 cooperates with the support wheel 85 and adjusts the tilt angle and height of the support wheel 85 by changing its own position to ensure that the cover net conforms to different terrains. In addition, the support roller 87 further shares the weight of the cover net and enhances the support effect. The abutment plate 88 provides basic support for the adjustment structure. When the adjusting bolt 89 is rotated, it pushes the adjusting plate 86 to slide in the abutment plate 88, accurately adjusting the working state of the support wheel 85 and ensuring that the cover net is laid flat and tightly.

[0041] The implementation principle of this application embodiment is as follows: During operation, the control motor 52 is started as a power source, and its output end drives the docking wheel 27 to rotate. The auxiliary gear 43 fixed on one side of the docking wheel 27 rotates accordingly. The auxiliary gear 43 transmits power to the main gear 41 and the follower gear 42 through the drive belt 51. The main gear 41 is fixedly connected to the mounting rod 21. After the power is transmitted to the mounting rod 21, it drives the net roll 1 to rotate, realizing the winding and unwinding of the cover net. At the same time, the follower gear 42 drives the adjusting roller 28 to rotate, adjusting the conveying angle of the net roll 1 and reducing the friction between the net roll 1 and the device. The rotating shaft 31 in the moving component 3 is fixed inside the extension rod 24. The moving wheels 32 on both sides and the universal wheels 33 at the bottom of the support plate 25 cooperate to enable the winding and unwinding mechanism 2 to move flexibly in different areas of the mine. The support frame 23 fixes the mounting rod 21 to the support plate 25 to provide stable support. The extension rod 24 connects to the moving component 3, and the connection is strengthened by the fixing rod 26. The protective frame 29 protects the drive component 5 and the transmission component 4 to ensure the stability and safety of the winding and unwinding process.

[0042] When it is necessary to lay the cover net, the laying mechanism 8 at the other end of the net roll 1 comes into play. The connecting rod 81 pulls the net roll 1, and the hook lock 84 connects to the external force to pull the pull rod 83, which drives the net roll 1 to unfold. The main shaft 82 serves as the rotation center, and the external support wheel 85 supports the ground during the laying process, reducing the friction between the cover net and the ground. The support roller 87 further shares the weight of the cover net, making the laying more stable. The adjusting plate 86 cooperates with the support wheel 85. By adjusting the bolt 89 to rotate the tension plate 88, the position of the adjusting plate 86 is changed, thereby adjusting the tilt angle and height of the support wheel 85, so that the cover net can closely fit different terrains to complete the laying.

[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
