[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In the prior art, there is a protective netting release device for stabilizing open-pit coal mine slopes, including a frame, with multiple casters at the bottom of the frame, and also including: Positioning components are used to fix the frame. The positioning components include: a fixing rod, which is slidably mounted on the frame and has a pointed bottom end.

Quick-release parts are used to engage locking mechanisms to secure the lid and storage compartment. Quick-release parts include: The push plate is mounted on the limit seat via a return spring. The push rod is mounted on the push plate and is in sliding fit with the limit seat. The push rod extends into the interior of the limit groove and contacts the limit block. The traction mechanism is used to pull and deploy the protective netting within the storage assembly. The traction mechanism includes: The tracked running gear structure has two tracks. Support plates are installed on top of the tracked walking structure, and connecting springs are installed between the two support plates. Clamping assembly, used to clamp the edge of the protective netting, includes: A movable plate, which can be movably mounted on a support plate; Clamping plate, the clamping plate is set on the movable plate; The pressure plate is adjustable and can be mounted on a movable plate. The braking mechanism, used to secure the safety net, includes: The placement board is set on the frame, and the top of the protective netting contacts the top of the placement board; The brake plate is adjustable and mounted on the storage box, and is located above the placement plate.

[0021] To cut the protective netting, a cutting mechanism is also included. This cutting mechanism and a braking mechanism work together to cut the protective netting. The cutting mechanism includes: The movable seat has a cutting groove on the placement plate, and the movable seat can be moved and set inside the cutting groove. The cutting pliers have one handle mounted on a movable base and the other handle mounted on a drive plate, with the top of the drive plate in contact with the bottom of the brake plate.

[0022] To ensure the cutting stability of the cutting pliers, a clamping assembly is also included, which includes: A clamping seat is located at the bottom of the drive plate via a clamping spring and a telescopic rod; The pressure roller is rotatably mounted on the pressure seat and contacts the top of the placement plate.

[0023] To facilitate the recycling of the tracked walking structure, a recycling mechanism is also included, which includes: A winding shaft is rotatably mounted on the frame, and a pull rope is wound around the winding shaft. The pull rope is connected to a support plate.

[0024] To improve the traction stability of the protective net, multiple insert rods are provided at the bottom of the pressure plate, and multiple slots matching the insert rods are provided on the clamp plate.

[0025] The above solution can reduce the obstruction caused by ground protrusions to the laying of protective netting, and has a higher laying accuracy, solving the problem of low laying accuracy caused by the existing throwing and releasing method.

[0026] Reference Figures 1-6 This invention provides a protective netting release device for stabilizing open-pit coal mine slopes, comprising: Bottom traveling vehicle 1 travels on the road at the bottom of the slope. Slide rails 5 are hinged to both sides of the bottom traveling vehicle 1. A paving frame 4 is slidably connected to the slide rails 5. A driving component for driving the paving frame 4 to move along the slide rails 5 is provided between the paving frame 4 and the bottom traveling vehicle 1. A protective net clamping component and a protective net cutting component are provided on the paving frame 4. Top traveling vehicle 2 travels on the road at the top of the slope. A roller 3 is horizontally rotatably connected to the top traveling vehicle 2. The axis of the roller 3 is set perpendicular to the slide rail 5. A protective net is wound around the roller 3. The end of the slide rail 5 away from the bottom traveling vehicle 1 is detachably connected to the top traveling vehicle 2.

[0027] The main function of the bottom traveling vehicle 1 is to move the slide rail 5 and the laying frame 4 in the open-pit coal mine; the main function of the top traveling vehicle 2 is to move the rolled protective netting in the open-pit coal mine; the bottom traveling vehicle 1 is located on the road below the slope, and the top traveling vehicle 2 is located on the road above the slope, so that when the slide rail 5 is connected between the bottom traveling vehicle 1 and the top traveling vehicle 2, the slide rail 5 can be in a state parallel to the slope surface; the main function of the slide rail 5 is to allow the laying frame 4 to move up and down along the coal mine slope, which facilitates the laying of the protective netting; the main function of the protective netting clamping component is to fix the free end of the protective netting to the laying frame 4, so that when the laying frame 4 moves down, the protective netting is pulled out from the roll 3 and laid flat on the slope; the main function of the protective netting cutting component is to automatically cut the laid protective netting from the roll 3 after the laying is completed; the slide rail 5 and the top traveling vehicle 2 are detachably connected, allowing the bottom traveling vehicle 1 and the top traveling vehicle 2 to be moved independently, improving the convenience of movement. Overall, this invention avoids the need for manual, high-intensity net-laying operations on slopes, resulting in a high degree of mechanization, high laying efficiency, and good laying effect. Furthermore, by setting up independently movable bottom and top traveling vehicles, it allows for more flexible relocation in open-pit coal mines. The connection between the sliding rail and the top traveling vehicle allows the protective net release device to be quickly put into working position, making it more adaptable to the working environment of open-pit coal mines.

[0028] In a further optimized design, two sets of connecting seats 7 are fixedly connected to the side wall of the top traveling vehicle 2 near the slope. The two connecting seats 7 are located at both ends of the top traveling vehicle 2. A pin 6 is slidably connected to the connecting seat 7. A pin hole is opened at the end of the slide rail 5 away from the bottom traveling vehicle 1. The pin 6 is adapted to the pin hole.

[0029] like Figure 1As shown, the slide rail 5 can be quickly connected to the top traveling vehicle 2 via the pin 6, so that the slide rail 5 can be erected on the slope and the laying of the protective net can begin. When the equipment needs to be moved, the pin 6 can be pulled out from the connecting seat 7 to separate the slide rail 5 from the top traveling vehicle 2. At this time, the bottom traveling vehicle 1 and the top traveling vehicle 2 can be moved to the predetermined positions on the roads at the bottom and top of the slope respectively, and then connected, which reduces the difficulty of relocation and improves the efficiency of relocation.

[0030] The scheme is further optimized. The protective net clamping assembly includes two sets of fixed clamping plates 18 that are fixedly connected to the two opposite side walls inside the laying frame 4, and two sets of movable clamping plates 17 that are vertically slidably connected to the two opposite side walls inside the laying frame 4. The movable clamping plates 17 are located above the fixed clamping plates 18. A telescopic rod 16 for adjusting the distance between the movable clamping plates 17 and the fixed clamping plates 18 is fixedly connected between the movable clamping plates 17 and the top of the laying frame 4.

[0031] In a further optimized design, a fixing rod 33 is fixedly connected to the bottom of the movable clamping plate 17, and a fixing groove 34 is provided on the top of the fixed clamping plate 18, with the fixing rod 33 and the fixing groove 34 being adapted to each other.

[0032] like Figure 2 As shown, after the free end of the protective net is pulled out from the roller 3, both ends are placed on the fixed clamping plate 18 respectively. Then, the telescopic rod 16 is extended to move the movable clamping plate 17 downward, clamping both ends of the protective net between the fixed clamping plate 18 and the movable clamping plate 17, thus connecting the protective net to the laying frame 4. By having the fixed rod 33 pass through the mesh of the protective net and insert it into the fixed groove 34, the stability of the clamping can be improved.

[0033] In this embodiment, the telescopic rod 16 can be a hydraulic telescopic rod.

[0034] The scheme is further optimized. The protective net cutting component includes a moving rail 13 that is horizontally fixedly connected to the laying frame 4. The moving rail 13 is located on the side of the laying frame 4 away from the bottom traveling vehicle 1. A slide block 14 is slidably connected to the moving rail 13. A moving drive component is provided between the moving rail 13 and the slide block 14. A saw blade 15 is rotatably connected to the bottom of the slide block 14. One end of the moving rail 13 is located on the outside of the laying frame 4, so that the slide block 14 and the saw blade 15 are located on the outside of the laying frame 4.

[0035] Further optimize the plan, such as Figure 2 As shown, the moving drive component includes a first motor 12 fixedly connected to the left end of the moving rail 13 and a transmission screw rotatably connected to the moving rail 13. The transmission screw is connected to the slide block 14 via a transmission connection. By rotating the transmission screw driven by the first motor 12, the slide block 14 can be moved along the moving rail 13 via a threaded transmission.

[0036] To further optimize the design, a motor is installed on the slide 14 to drive the rotation of the saw blade 15.

[0037] like Figure 1 and Figure 2 As shown, after the laying frame 4 pulls the protective net downward to lay the protective net, the laying frame 4 moves up to the top along the slide rail 5, and then the first motor 12 drives the slide block 14 to move along the moving rail 13, and rotates the saw blade 15 to cut off the part of the protective net near the roller 3, thus completing the laying of the protective net.

[0038] The scheme was further optimized by fixing the card holders 11 at both ends of the bottom of the laying frame 4, and the card holders 11 were slidably connected to the slide rail 5. The drive assembly includes two sets of first sprockets 22 rotatably connected within the slide rail 5. The two first sprockets 22 are located at both ends of the slide rail 5, and a drive chain 21 is wound between the two first sprockets 22. Insert rods 19 are vertically slidably connected to both ends of the laying frame 4. The bottom of the insert rods 19 passes through the side wall of the laying frame 4, the card seat 11, and the slide rail 5 in sequence and is inserted into the drive chain 21. A rotation drive mechanism is provided between the two first sprockets 22 near the bottom traveling vehicle 1 and the bottom traveling vehicle 1.

[0039] like Figure 2 As shown, a spring 20 is provided between the top of the insertion rod 19 and the laying frame 4 to ensure that the insertion rod 19 is always inserted into the drive chain 21.

[0040] The scheme is further optimized. The rotation drive mechanism includes two sets of second sprockets 23 rotatably connected inside the bottom traveling vehicle 1. The two second sprockets 23 are respectively connected to the two first sprockets 22 through the drive shaft. The slide rail 5 is hinged to the bottom traveling vehicle 1 through the drive shaft. The bottom traveling vehicle 1 also has two sets of third sprockets 24 rotatably connected inside. The two third sprockets 24 are respectively connected to the two second sprockets 23 through the chain. The two third sprockets 24 are coaxially fixedly connected to each other through the transmission rod 25. A power component is provided between the transmission rod 25 and the bottom traveling vehicle 1.

[0041] The scheme is further optimized. The power components include a second motor 27 fixedly connected inside the bottom traveling vehicle 1 and a gear 26 fixedly sleeved on the transmission rod 25. The second motor 27 and the gear 26 are connected in a transmission connection.

[0042] like Figures 1-2 , Figures 4-5As shown, when the laying frame 4 needs to move downwards along the slide rail 5, the second motor 27 drives the gear 26 to rotate, which in turn drives the two third sprockets 24 to rotate via the transmission rod 25. The third sprockets 24 drive the second sprocket 23 to rotate via the chain, and the second sprocket 23 drives the first sprocket 22 to rotate, causing the drive chain 21 to move in the slide rail 5. This drives the chain 21 to pull the insert rod 19, thus moving the laying frame 4 downwards along the slide rail 5. Similarly, controlling the second motor 27 to rotate in the opposite direction will pull the laying frame 4 upwards.

[0043] like Figure 5 As shown, the drive shaft between the second sprocket 23 and the first sprocket 22 not only serves as a drive mechanism, but also allows the slide rail 5 to rotate relative to the bottom traveling vehicle 1.

[0044] The scheme is further optimized. A fixed frame 8 is fixedly connected to the top traveling carriage 2. The fixed frame 8 is set on the side of the roller 3 near the slide rail 5. A fixed flattening roller 10 is rotatably connected inside the fixed frame 8. A slider 30 is slidably connected to the two opposite side walls of the fixed frame 8. A movable flattening roller 9 is rotatably connected between the two sliders 30. The movable flattening roller 9 is located above the fixed flattening roller 10. Two sets of third motors 28 are fixedly connected inside the fixed frame 8. A lead screw 29 is driven and connected to the two third motors 28 respectively. The two lead screws 29 are driven and connected to the two sliders 30 respectively.

[0045] like Figure 3 As shown, by controlling the third motor 28 to drive the lead screw 29 to rotate, the sliding block 30 can be controlled to lower the moving flattening roller 9, clamping the protective net between the moving flattening roller 9 and the fixed flattening roller 10, so that the protective net can be laid on the slope after being flattened and guided, thus improving the laying effect.

[0046] To further optimize the design, fixed rods 31 are fixedly connected to both sides of the bottom traveling vehicle 1, and limit holes are opened on both sides of the laying frame 4. Connecting pins 32 are inserted into the fixed rods 31, and the connecting pins 32 are inserted into the limit holes to limit the laying frame 4 on the bottom traveling vehicle 1.

[0047] like Figure 6 During the relocation, the slide rail 5 can be flipped and the position of the laying frame 4 can be adjusted so that the limiting hole is aligned with the connecting pin 32 on the fixing rod 31. The connecting pin 32 is then inserted into the limiting hole to fix the laying frame 4 to the fixing rod 31. At this time, the slide rail 5 is detached from the slope and the bottom traveling vehicle 1 can move freely.

[0048] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0049] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
