Description

Technical Field

[0001] This invention relates to the field of geological disaster prevention and control technology, specifically to a slope protection net laying device and method for geological disaster prevention and control. Background Technology

[0002] In geological disaster prevention and control, the laying of slope protection nets is a key measure, which can effectively prevent damage to slopes from disasters such as rockfalls and landslides. At present, the laying of slope protection nets mostly relies on manual labor or semi-mechanized equipment, which has problems such as low efficiency, high labor intensity and insufficient laying accuracy.

[0003] Manual installation is not only labor-intensive and inefficient, but existing semi-mechanized equipment is often limited in function, typically only able to unroll the protective netting. The length measurement, cutting, and pulling of the netting still require manual assistance, resulting in a cumbersome construction process and low overall efficiency. Furthermore, these devices are inadequate in terms of material storage, failing to provide convenient storage and quick replacement of the protective netting rolls, further hindering the construction progress.

[0004] Therefore, the present invention provides a slope protection net laying device and method for geological disaster prevention and control. Summary of the Invention

The lifting plate is fixed at the center of the bottom of the storage bin.

[0020] Each of the lifting seats has a drive screw threaded through its center, and guide rods slidably pass through both ends of the lifting seat. A drive motor is installed at the upper end of the movable base corresponding to the bottom end of the drive screw. The output end of the drive motor is fixed to the bottom end of the drive screw. The top end of the drive screw is rotatably connected to the protective plate at the upper end of the movable base. The two guide rods are fixed on the movable base.

[0021] As a further technical solution of the present invention, a limiting component for limiting the unwinding frame is provided at both ends of the protective net roll on the rear side. The limiting component includes roller grooves symmetrically opened on the inner wall of the rear end of the unwinding frame, and the rollers at both ends of the roller roll roll in the roller grooves.

[0022] The limiting component also includes a fixing plate symmetrically installed at the top of the rear end of the unwinding frame. An electric push rod is installed at the upper end of the fixing plate. The telescopic end of the electric push rod passes through the fixing plate and is connected to a baffle. The baffle is slidably disposed on the rear end face of the unwinding frame.

[0023] As a further technical solution of the present invention, the traction component includes a movable frame and a universal self-locking wheel provided at the bottom of the movable frame. A handle is symmetrically installed at the top of the movable frame, and a rotating disk is rotatably connected to the top of the movable frame. A second drive screw extending into the handle is threadedly connected to the middle of the rotating disk. The handle has a hollow structure inside, and the rotating disk and the second drive screw are threadedly connected.

[0024] A fixing rod is vertically installed at the top of the second drive screw. Both ends of the fixing rod are hinged to a lower bracket. The upper end of the lower bracket is connected to an upper bracket via a hinge. The surface of the lower bracket is evenly distributed with slots, and the lower surface of the upper bracket is evenly distributed with teeth. When the upper bracket is engaged with the lower bracket, the teeth are inserted into the slots.

[0025] The upper surface of the lower bracket is symmetrically provided with positioning screw holes on one side. Two positioning screws are rotatably connected to the two symmetrical positioning screw holes on the upper bracket, and the lower end of the positioning screws is screwed into the positioning screw holes.

[0026] As a further technical solution of the present invention, a traction frame is welded to the rear end of the mobile base, a PLC control cabinet is installed on one side of the mobile base, a power supply cabinet is installed on the other side of the mobile base, and wheels with brake discs are installed at the four corners of the bottom of the mobile base.

[0027] A method for laying a slope protection netting device for geological disaster prevention, the method specifically includes the following steps:

[0028] Step 1: Move the device to the slope construction area by traction equipment, fix the device by the brake disc of the wheel at the bottom of the moving base, connect the power supply, and set parameters such as the length of the protective netting to be laid through the PLC control cabinet;

[0029] Step 2: If there is no protective netting roll in the storage bin, adjust the storage bin to a suitable height using the lifting assembly, place the protective netting roll into the chamber of the storage bin one by one, and insert a baffle to block it;

[0030] Step 3: When loading the protective net roll onto the unwinding frame, first pull out the baffle at the bottom of the storage silo chamber, slide a protective net roll near the unwinding frame in the upper chamber toward the unwinding frame, and let the roller wheels at both ends of its roller shaft enter the roller wheel groove. The baffle is pushed by the electric push rod of the limiting component to limit the protective net roll.

[0031] Step 4: Pull out the free end of the protective net roll, and pass it through the guide roller, below the measuring wheel, between the feed rollers, and the front pressure roller in sequence, until the end of the protective net extends out of the front end of the unwinding frame;

[0032] Step 5: Move the two traction components to both sides of the end of the protective net, adjust their height so that both ends of the protective net are placed on the lower brackets of the two traction components respectively, close the upper brackets and fix them with the positioning screws to complete the clamping of both ends of the protective net;

[0033] Step Six: Start the device. The feed roller, driven by the drive motor, conveys the protective net forward. At the same time, the traction component moves along the slope with manual assistance, pulling out the protective net and laying it on the slope. The measuring mechanism monitors the length of the protective net in real time and transmits the data to the PLC control cabinet.

[0034] Step 7: When the length of the protective net reaches the preset value, the PLC control cabinet controls the feed roller to stop working, and at the same time controls the hydraulic cylinder of the cutting mechanism to extend, driving the cutter to move downward to cut the protective net.

[0035] Step 8: After the cutting is completed, release the clamp of the traction component on the end of the protective net and fix it on the slope. Then, the traction component returns to the front end of the unwinding frame and repeats steps 4 to 7 above to lay the next section of the protective net.

[0036] Furthermore, if the protective netting rolls in the upper chamber of the storage silo are used up, the storage silo can be raised using the lifting component, so that the protective netting rolls in the lower chamber can be raised to the upper chamber, and then step 3 can be repeated for feeding.

[0037] This invention provides a slope protection net laying device and method for geological disaster prevention and control, which has the following advantages compared with the prior art:

[0038] 1. A slope protection net laying device and method for geological disaster prevention and control, which realizes automatic unwinding of the protection net through the coordinated action of the unwinding frame, the feeding roller and the traction component. The feeding roller realizes automatic feeding of the protection net under the drive of the drive motor, which reduces the intensity of manual labor. At the same time, with the help of manual traction, the accuracy of the protection net laying process can be improved and the laying efficiency can be increased.

[0039] 2. A slope protection net laying device and method for geological disaster prevention and control. During the laying process, the measuring wheel in the measuring mechanism works with the electronic encoder to monitor the length of the protective net in real time, ensuring the accuracy of the laying length and ensuring that the laying length meets the construction requirements. At the same time, with the cooperation of the cutting mechanism, the protective net can be quickly cut by the hydraulic cylinder driven by the cutter after a certain length is unrolled, without the need for manual cutting.

[0040] 3. A slope protection net laying device and method for geological disaster prevention and control, which can store multiple protective net rolls at the same time by adding a storage bin, reducing the frequency of replacing net rolls and improving construction efficiency. Secondly, the lifting component can adjust the height of the storage bin, which facilitates better replacement of protective net rolls during the laying process, saving time and effort. At the same time, with the cooperation of the limiting component, the protective net rolls after replacement on the unwinding frame can be limited, improving the stability of the unwinding.

[0059] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] Please see Figure 1-2This invention provides a technical solution for a slope protection net laying device for geological disaster prevention: A slope protection net laying device for geological disaster prevention includes a mobile base 1, a traction frame 11 welded to the rear end of the mobile base 1, a PLC control cabinet 12 installed on one side of the mobile base 1, a power cabinet 13 installed on the other side of the mobile base 1, wheels with brake discs installed at the four corners of the bottom of the mobile base 1, the traction frame 11 at the rear end can be connected to an external traction device to realize the overall movement of the device, the PLC control cabinet 12 installed on the mobile base 1 is used to control the operation of the entire device, and the power cabinet 13 provides power support for the device;

[0061] like Figure 5 As shown, it also includes a storage bin 2, which is installed on the upper rear side of the mobile base 1. The inner side of the storage bin 2 is divided into two chambers by a bearing plate. Each chamber can store multiple protective net rolls 6. The bottom front end of each chamber is provided with a slot 21, and a baffle 22 for blocking the protective net rolls 6 is inserted into the slot 21. The storage bin 2 is open at the rear end of the unwinding frame 3.

[0062] like Figure 4-6 As shown, a lifting assembly 4 is installed between the storage silo 2 and the movable base 1. The storage silo 2 is positioned on the upper part of the movable base 1 via the lifting assembly 4. The lifting assembly 4 includes lifting seats 41 symmetrically installed on the lower ends of both sides of the storage silo 2. A lifting plate 42 is connected between the two lifting seats 41. The lifting plate 42 is fixed at the bottom center of the storage silo 2. A drive screw 45 is threaded through the middle of each lifting seat 41, and guide rods 44 slide through both ends of the lifting seat 41. A drive motor 43 is installed at the upper end of the movable base 1 corresponding to the bottom end of the drive screw 45. The output end of the drive motor 43 is fixed to the bottom end of the drive screw 45. The top end of the drive screw 45 is rotatably connected to the protective plate at the upper end of the movable base 1. The two guide rods 44 are fixed on the movable base 1. When the protective net roll 6 of the upper chamber of the storage silo 2 is laid, it is necessary to... Replace the protective net roll 6 in the lower chamber onto the unwinding frame 3. At this time, the PLC control cabinet 12 will synchronously control the two drive motors 43 to rotate synchronously, thereby synchronously driving the two drive screws 45 to rotate. Then, under the guidance of their respective guide slides 44, the two lifting seats 41 together drive the storage bin 2 to move up and down through the lifting plate 42, thereby adjusting the height of the storage bin 2, so that the protective net roll 6 in the lower chamber rises to the upper chamber (i.e., the original position of the upper chamber). When replacement is needed, pull out the baffle 22 on the slot 21, and manually roll the protective net roll 6 to the unwinding frame 3. Before this, the limiting component 7 should be opened, and then manually roll the protective net roll 6 to the inside of the unwinding frame 3, so that the rollers 62 on both sides of the protective net roll 6 move into the roller grooves 74. Then, the limiting component 7 is used to limit the movement, and the replacement can be achieved.

[0063] like Figure 7-8 As shown, it also includes an unwinding frame 3, which is installed on the upper end of the movable base 1 corresponding to one side of the storage bin 2, and is used to unwind and lay the protective net. The front side of the unwinding frame 3 is equipped with a front pressure roller 31 through a bracket. The inner side of the unwinding frame 3 is equipped with three guide rollers 34 located directly below the measuring wheel 332 and on one side thereof. Two of the guide rollers 34 are symmetrical in the vertical direction, and the other guide roller 34 is symmetrical with the measuring wheel 332. After the protective net is unwound from the protective net roll 6, it passes through the guide rollers 34 for guidance, the measuring wheel 332 for measurement, and the feed rollers 35 for conveying in sequence. The guide rollers 34 play a guiding and tensioning role for the protective net, ensuring that the protective net is conveyed smoothly.

[0064] like Figure 8 As shown, two feed rollers 35 are symmetrically and rotatably installed on the inner side of the unwinding frame 3 near the guide roller 34. One end of each feed roller 35 is fixed with a gear 36, and the two gears 36 mesh with each other. A drive motor 37 is installed on the outer side of the unwinding frame 3 via a bracket. The output end of the drive motor 37 is fixed to one end of one of the gears 36. A reducer is provided at the output end of the drive motor 37, so that the feed rollers 35 can achieve synchronous reverse rotation under the drive of the drive motor 37 through the two meshing gears 36, thus conveying the protective net forward. In addition, the surface of the feed rollers 35 is not smooth, ensuring feeding efficiency.

[0065] The unwinding frame 3 has a protective net roll 6 located near the storage bin 2 on its inner rear end. A measuring mechanism 33 for monitoring the length of the protective net roll is also located near the protective net roll 6 on the inner side of the unwinding frame 3. The measuring mechanism 33 includes a horizontal plate 331 installed on the inner side of the unwinding frame 3 above the protective net. A measuring wheel 332 is rotatably mounted on the bottom center of the horizontal plate 331 via a connecting frame. An electronic encoder 333 is installed at the bottom end of the connecting frame corresponding to the axle of the measuring wheel 332. The axle of the measuring wheel 332 is connected to the output end of the electronic encoder 333. When the measuring mechanism 33 is working, the protective net drives the measuring wheel 332 to rotate, and the axle of the measuring wheel 332 drives the electronic encoder 333 to work. The electronic encoder 333 converts the rotation signal into an electrical signal and transmits it to the PLC control cabinet 12, thereby achieving real-time monitoring of the length of the protective net roll.

[0066] like Figure 7As shown, the front end of the unwinding frame 3 is equipped with a cutting mechanism 32 for cutting the protective netting. The cutting mechanism 32 includes a top frame 321 installed above the front end of the unwinding frame 3. A hydraulic cylinder 322 is installed at the top center of the top of the top frame 321. The telescopic end of the hydraulic cylinder 322 extends through the top frame 321 and connects to a cutter 323 on its inner side. A base plate 326 is fixed on the inner side of the front end of the unwinding frame 3, directly below the cutter 323. Slide seats 324 are installed on both sides of the cutter 323. A slide rail 325 is fixed on the inner side of the unwinding frame 3, corresponding to the slide seats 324. The two sides of the cutter 323 slide on the slide rail 325 through the slide seats 324 to ensure the stability of the cutter 323 when it moves down, thereby improving the effective cutting of the protective netting.

[0067] Through the effective cooperation of the cutting mechanism 32 and the measuring mechanism 33, when the length of the protective net reaches the preset value, the PLC control cabinet 12 controls the cutting mechanism 32 to work. The hydraulic cylinder 322 pushes the cutter 323 to move downward along the slide rail 325, and cooperates with the base plate 326 to cut the protective net. The front pressure roller 31 on the front side of the unwinding frame 3 can press the end of the cut protective net, which is convenient for subsequent traction and laying.

[0068] like Figure 7 As shown, a limiting component 7 for limiting the protective net roll 6 is also provided at both ends of the rear side of the unwinding frame 3 near the protective net roll 6. The limiting component 7 includes roller grooves 74 symmetrically opened on the inner wall of the rear end of the unwinding frame 3. A roller 61 is provided through the middle of the protective net roll 6, and roller wheels 62 are rotatably connected to both ends of the roller 61. The roller wheels 62 at both ends of the roller 61 roll in the roller grooves 74. The limiting component 7 also includes a fixing plate 71 symmetrically installed on the top of the rear end of the unwinding frame 3. An electric push rod 72 is installed on the upper end of the fixing plate 71. The telescopic end of the electric push rod 72 passes through the fixing plate 71 and is connected to a baffle 73. The baffle 73 is slidably arranged on the rear end face of the unwinding frame 3. During the unwinding process, the roller wheels 62 at both ends of the roller 61 of the protective net roll 6 on the unwinding frame 3 roll in the roller grooves 74. The electric push rod 72 in the limiting component 7 can push the baffle 73 to move up and down to limit the protective net roll 6 and prevent it from deviating during the unwinding process.

[0069] like Figure 9-10As shown, it also includes two traction components 5, which are symmetrically arranged to clamp and fix the two ends of the protective net released by the unwinding frame 3, and assist the unwinding frame 3 in pulling out the protective net. The traction component 5 includes a movable frame 51 and a universal self-locking wheel 52 at the bottom of the movable frame 51. A handle 53 is symmetrically installed at the top of the movable frame 51, and a rotating disk 54 is rotatably connected to the top of the movable frame 51. A second drive screw 55 extending into the handle 53 is threadedly connected to the middle of the rotating disk 54. The handle 53 has a hollow structure inside. The rotating disk 54 and the second drive screw 55 are threadedly connected. A rotating handle is provided on the outer wall of the rotating disk 54. The rotating disk 54 is rotatably set at the top of the movable frame 51. By rotating the rotating disk 54, the second drive screw 55 can be extended or inserted on the movable frame 51 to realize the height adjustment of the lower card seat 57 and the upper card seat 58.

[0070] A fixed rod 56 is vertically installed at the top of the drive screw 55. The two ends of the fixed rod 56 are hinged to a lower bracket 57. The upper end of the lower bracket 57 is connected to an upper bracket 58 via a hinge. The surface of the lower bracket 57 is evenly distributed with slots 510. The lower surface of the upper bracket 58 is evenly distributed with teeth 59. When the upper bracket 58 is engaged with the lower bracket 57, the teeth 59 are inserted into the slots 510. The purpose of the engagement of the teeth 59 and the slots 510 is to tighten the end of the protective net. At the same time, the teeth 59 can be inserted into the mesh of the protective net, further improving the connection and fixation between the protective net and the traction component 5.

[0071] The upper surface of the lower bracket 57 is symmetrically provided with positioning screw holes 511 on one side. Two positioning screws 512 are rotatably connected to the two symmetrical positioning screw holes 511 on the upper bracket 58. The lower end of the positioning screw 512 is screwed into the positioning screw hole 511, and the upper end of the positioning screw 512 is rotatably set on the upper bracket 58. When the upper bracket 58 is locked on the lower bracket 57, the positioning screw 512 is screwed so that its lower end is screwed into the positioning screw hole 511, thereby fixing the two together.

[0072] When the aforementioned traction component 5 is in operation, the manual gripping of the handle 53 pushes the moving frame 51, causing the universal self-locking wheel 52 to move on the slope, thereby driving the protective net to be laid. When it is necessary to adjust the height of the end of the protective net, the rotating disk 54 can be rotated to drive the screw 55 to move the fixing rod 56 up and down, adjusting the height of the lower clamp 57 and the upper clamp 58. Next, when fixing, place both ends of the protective net on the lower clamp 57, close the upper clamp 58, so that the clamping teeth 59 are inserted into the clamping slot 510, and then screw the positioning screw 512 into the positioning screw hole 511 to achieve clamping and fixing of the protective net. Subsequently, the manual pushing of the traction component 5 assists the unwinding frame 3 in pulling out the protective net and laying it on the slope.

[0073] A method for laying a slope protection netting device for geological disaster prevention, the method specifically includes the following steps:

[0074] Step 1: Move the device to the slope construction area by traction equipment, fix the device by the brake disc of the bottom wheel of the movable base 1, connect the power supply, and set parameters such as the length of the protective netting through the PLC control cabinet 12;

[0075] Step 2: If there is no protective net roll 6 in the storage bin 2, adjust the storage bin 2 to a suitable height by lifting component 4, put the protective net roll 6 into the cavity of the storage bin 2 in sequence, and insert baffle 22 to block it;

[0076] Step 3: When loading the protective net roll 6 onto the unwinding frame 3, first pull out the baffle 22 at the bottom of the storage bin 2 chamber, slide one of the protective net rolls 6 near the unwinding frame 3 in the upper chamber toward the unwinding frame 3, and let the roller wheels 62 at both ends of its roller shaft 61 enter the roller wheel groove 74. The electric push rod 72 of the limiting component 7 pushes the baffle 73 to limit the protective net roll 6.

[0077] Step 4: Pull out the free end of the protective net roll 6 and pass it through the guide roller 34, below the measuring wheel 332, between the feed rollers 35 and the front pressure roller 31 in sequence until the end of the protective net extends out of the front end of the unwinding frame 3.

[0078] Step 5: Move the two traction components 5 to both sides of the end of the protective net, adjust their height so that the two ends of the protective net are respectively placed on the lower clamps 57 of the two traction components 5, close the upper clamps 58 and fix them with the positioning screws 512 to complete the clamping of the two ends of the protective net.

[0079] Step 6: Start the device. The feed roller 35, driven by the drive motor 37, conveys the protective net forward. At the same time, the traction component 5 moves along the slope with manual assistance, pulling out the protective net and laying it on the slope. The measuring mechanism 33 monitors the length of the protective net in real time and transmits the data to the PLC control cabinet 12.

[0080] Step 7: When the length of the protective net reaches the preset value, the PLC control cabinet 12 controls the feed roller 35 to stop working, and at the same time controls the hydraulic cylinder 322 of the cutting mechanism 32 to extend, driving the cutter 323 to move downward to cut the protective net.
