Description

Technical Field

[0001] This invention relates to the field of slope protection technology, specifically to a netting device and method for steep slopes. Background Technology

[0002] Highway greening slopes refer to functional greening projects that combine planting, engineering protection, and ecological restoration on the slopes on both sides of the highway subgrade to stabilize the slopes, prevent soil erosion, and beautify the roadside environment. It has two core values: protection and ecological function.

[0003] For sections with steep slopes or poor soil and rock stability, it is necessary to combine engineering protection slope netting with greening operations to form a composite system of "engineering protection + plant protection". The slope netting is mostly made of synthetic materials for protection.

[0004] Currently, the installation of mesh on steep slopes is mostly carried out by erecting scaffolds. The overall slope mesh installation cycle is long, the installation cost is high, and there are certain safety hazards. It requires the coordinated work of staff and cannot be quickly adapted to different steep slope environments, resulting in poor adaptability and high investment costs, which is not conducive to the efficient implementation of the overall mesh installation work. Summary of the Invention

[0005] The purpose of this invention is to provide a netting device and method for steep slopes to solve the above-mentioned technical problems.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0007] This invention relates to a netting device for steep slopes, comprising a frame consisting of two opposing vertical plates, characterized in that it further includes:

[0008] Two counterweights are symmetrically arranged on both sides of the front end of the frame to maintain the stability of the frame when it is tilted.

[0009] The release roller is rotatably mounted on the frame. Two take-up reels are symmetrically mounted on both sides of the frame. Steel ropes are wound on the two take-up reels. A drive motor connected to the release roller is mounted on one side of the frame via a bracket.

[0010] Two pressing rollers are symmetrically arranged at the bottom of both sides of the frame. The continuous pressing action of the slope net is completed by the two pressing rollers.

[0011] The unfolding mechanism, mounted on the frame, is used for unfolding the slope netting.

[0012] The dynamic tensioning mechanism is mounted on the frame and linked with the unfolding mechanism. The dynamic tensioning control of the slope net is achieved through the dynamic tensioning mechanism.

[0013] Furthermore, it also includes:

[0014] Two guide rollers are symmetrically rotated and positioned at the bottom of both sides of the frame to guide the steel rope;

[0015] Two guide wheels are symmetrically mounted on both sides of the frame via a bracket, and each guide wheel is positioned on one side of a guide roller. The rotation of the steel rope is guided by the cooperation of the guide wheels and the guide rollers.

[0016] Furthermore, each pressing roller includes:

[0017] Two vertical rods are symmetrically slidably installed on the frame, and each vertical rod has a threaded area on the outside.

[0018] Two threaded baffles are screwed onto the top of each vertical rod;

[0019] Two limit springs are respectively sleeved on the outside of the two vertical rods, and each limit spring is respectively set between the threaded baffle and the frame.

[0020] Furthermore, each pressing roller also includes:

[0021] The positioning roller is rotatably positioned between two vertical rods. The positioning roller is used to press the slope netting. Multiple strip-shaped components are arranged in a circular array on the outer surface of the positioning roller.

[0022] Furthermore, the deploying organization includes:

[0023] Two No. 1 gears are correspondingly driven and sleeved on both sides of the release roller;

[0024] Two No. 2 gears are symmetrically rotated and arranged on both sides of the frame and respectively mesh with two No. 1 gears;

[0025] The control shaft is rotatably mounted inside the frame. At both ends of the control shaft, there are No. 3 gears that mesh with the two No. 2 gears. Two spiral components are symmetrically arranged on the control shaft. The slope net is controlled to unfold to both sides by rotating the two spiral components.

[0026] Furthermore, the organization also includes:

[0027] Two No. 1 slides are symmetrically opened on both sides of the frame, and a No. 1 slider is slidably engaged in each No. 1 slide.

[0028] The extrusion shaft is rotatably mounted on two sliders No. 1 via a bracket, and the extrusion shaft is set parallel to the control shaft;

[0029] Two springs, each numbered 1, are respectively installed in two grooves and connected to the slider number 1.

[0030] Furthermore, the dynamic tensioning mechanism includes:

[0031] Two No. 2 slides are symmetrically opened on the frame, and a No. 2 slider is slidably engaged in each No. 2 slide.

[0032] Two No. 2 springs are respectively set in the two No. 2 slide grooves and connected to the No. 2 slider;

[0033] Two flexible components are respectively set on two second sliders, and a tension roller is rotatably installed between the two flexible components.

[0034] Furthermore, this dynamic tensioning mechanism also includes:

[0035] Two cam components are fixedly sleeved on both ends of the control shaft;

[0036] Two contact wheels are mounted on two second sliders via brackets, and each contact wheel contacts the corresponding cam component.

[0037] Furthermore, each flexible component includes:

[0038] A sliding seat is set on the second slider. A sliding plate is slidably engaged in the sliding seat. The sliding plates of the two flexible parts are rotatably connected to both ends of the tension roller.

[0039] A tension spring is installed between the sliding seat and the slide plate, and the movement of the tension roller is controlled by the tension spring.

[0040] This invention also provides a method for using netting on steep slopes, which specifically includes the following steps:

[0041] Step 1: First, temporarily store the slope net on the release roller. Then, transfer the net hanging device to the waiting area at the top of the slope. After that, fix the steel ropes of the two take-up reels on the frame to the top of the slope.

[0042] Step 2: Then start the drive motor to control the release roller and the slope net on it to release. At the same time, rotate the two take-up reels to release the steel rope. When releasing the slope net, the overall position of the frame is moved and traveled simultaneously to carry out the self-propelled slope net laying work.

[0043] Step 3: During operation, the slope net is expanded to both sides using the unfolding mechanism to ensure the flatness of the slope net;

[0044] Step 4: The dynamic tensioning mechanism in operation can control the tension of the slope net, so that the slope net is laid with a certain tension, avoiding the situation of wrinkles in the laid slope net.

[0045] Compared with the prior art, the beneficial effects of the present invention are:

[0046] 1. This invention utilizes a release roller and two take-up reels. When the release roller releases the slope netting onto the slope, the take-up reels rotate synchronously to release the steel rope. The frame moves automatically on the slope under its own weight, thus completing the automatic slope netting laying work, reducing laying costs and improving construction efficiency. At the same time, two spaced positioning rollers continuously move and press the slope netting, ensuring that the laid slope netting can stably adhere to the soil without subsequent adjustments, saving time and labor.

[0047] 2. This invention features an unfolding mechanism. When the release roller rotates, it drives the control shaft and two No. 3 gears to rotate. Since the control shaft is equipped with a spiral component, the slope net can be expanded by the spiral component during the rotation of the control shaft, thus unfolding the slope net and avoiding the problem of wrinkles. Furthermore, with the cooperation of the extrusion shaft, the slope net can be stably and dynamically attached to the control shaft, ensuring the unfolding effect of the slope net and facilitating the overall laying work.

[0048] 3. This invention features a dynamic tensioning mechanism. Under normal conditions, the contact tension spring controls the tension of the slope net. Simultaneously, as the control shaft rotates, a pre-set cam on it follows the rotation. During a single rotation, the cam contacts the contact wheel, forcing the second slider and the tension roller to move further, increasing the movement distance of the tension roller. This allows for intermittent tension control during slope net laying, dynamically controlling the tension of the slope net, ensuring a good laying condition, and improving construction quality.

[0049] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0060] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0061] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0062] Example 1: The present invention provides a technical solution: such as Figures 1 to 5 As shown, a netting device and method for steep slopes includes a frame 1, which consists of two opposing vertical plates. Two reinforcing rods are symmetrically installed at the bottom between the two vertical plates. The device also includes:

[0063] Two counterweights 2 are symmetrically arranged on both sides of the front end of the frame 1 to keep the frame 1 stable in the tilted state.

[0064] Release roller 3 is rotatably mounted on frame 1. Two blocking circular plates are symmetrically arranged on release roller 3, forming a winding space on release roller 3 for winding and storing slope netting. Two take-up reels 4 are symmetrically rotatably mounted on both sides of frame 1, with steel rope 5 wound on the two take-up reels 4. A drive motor 6 connected to release roller 3 is mounted on one side of frame 1 via a bracket. A battery compartment that provides power to drive motor 6 is also mounted on one side of frame 1.

[0065] Two pressing rollers are symmetrically arranged at the bottom of both sides of the frame 1. The continuous pressing action of the slope net is completed by the two pressing rollers.

[0066] The unfolding mechanism, mounted on frame 1, is used for unfolding the slope netting.

[0067] The dynamic tensioning mechanism is set on the frame 1 and linked with the unfolding mechanism. The dynamic tensioning control of the slope net is completed through the dynamic tensioning mechanism.

[0068] Also includes:

[0069] Two guide rollers 7 are symmetrically rotated and positioned at the bottom of both sides of the frame 1 to guide the steel rope 5;

[0070] Two guide wheels 8 are symmetrically rotated on both sides of the frame 1 via a bracket, and the two guide wheels 8 are respectively located on one side of the two guide rollers 7. The rotation of the steel rope 5 is guided by the cooperation of the guide wheels 8 and the guide rollers 7.

[0071] Each pressing roller includes:

[0072] Two vertical rods 9 are symmetrically slidably mounted on the frame 1, and each vertical rod 9 has a threaded area on its exterior.

[0073] Two threaded baffles 10 are screwed onto the top of each vertical rod 9, and each threaded baffle 10 is configured to mate with the threaded area.

[0074] Two limiting springs 11 are respectively sleeved on the outside of the two vertical rods 9, and each limiting spring 11 is respectively set between the threaded baffle 10 and the frame 1;

[0075] Each pressing roller also includes:

[0076] The positioning roller 12 is rotatably set between the two vertical rods 9. The positioning roller 12 completes the pressing work of the slope net. Multiple strip-shaped pieces are arranged in a circular array on the outer surface of the positioning roller 12.

[0077] It is worth noting that during self-propelled paving: since the frame 1 is connected to the top of the slope via steel rope 5, when the release roller 3 releases the slope netting onto it, the take-up reel 4 rotates synchronously to release the steel rope 5. The frame 1, under its own weight, automatically moves along the slope, thus completing the automatic slope netting paving work. This reduces paving costs, safety hazards, and construction efficiency. Two pressing rollers are also provided, and two positioning rollers 12 guide the slope netting. The two spaced positioning rollers 12 continuously press and compress the slope netting, ensuring stable adhesion between the laid slope netting and the soil, eliminating the need for subsequent adjustments and saving time and effort. Furthermore, the positioning rollers 12, through the cooperation of the limit spring 11 and the vertical rod 9, form a flexible force, allowing them to actively move and avoid protrusions, preventing significant changes in the overall shape of the frame 1 and ensuring the stability of the slope netting paving.

[0078] Among them, the drive motor 6 and other electrical components are all connected to switches via wires, and the switches are electrically connected to controllers. The specific structure of the controllers is not limited.

[0079] Example 2: Based on the unfolding mechanism provided in Example 1, this example provides a further technical solution for the unfolding mechanism.

[0080] like Figure 6 and Figure 7 As shown, the deployment mechanism includes:

[0081] Two No. 1 gears 13 are correspondingly driven and sleeved on both sides of the release roller 3;

[0082] Two No. 2 gears 14 are symmetrically rotated and arranged on both sides of the frame 1 and respectively mesh with two No. 1 gears 13;

[0083] The control shaft 15 is rotatably mounted inside the frame 1. At both ends of the control shaft 15, the third gear 16 is driven and connected to the two second gears 14. Two spiral parts 17 are symmetrically arranged on the control shaft 15. The two spiral parts 17 are rotated to control the slope net to unfold to both sides to avoid wrinkles. The spiral direction of the two spiral parts 17 is specifically extended from the center of the control shaft 15 to the two side edges to complete the unfolding of the slope net.

[0084] In this embodiment of the invention, the unfolding mechanism further includes:

[0085] Two No. 1 slide grooves 18 are symmetrically opened on both sides of the frame 1, and a No. 1 slider 19 is slidably engaged in each No. 1 slide groove 18.

[0086] The extrusion shaft 20 is rotatably mounted on two first sliders 19 via a bracket, and the extrusion shaft 20 is arranged parallel to the control shaft 15;

[0087] Two springs 21 are respectively set in two slide grooves 18 and connected to sliders 19. The movement of sliders 19 within slide grooves 18 is controlled by the springs 21.

[0088] It is worth noting that when unfolding the slope net: an unfolding mechanism is provided. When the release roller 3 rotates, it drives the two No. 1 gears 13 to rotate. Through the transmission of the No. 2 gear 14, the control shaft 15 and the two No. 3 gears 16 are driven to rotate. Since the control shaft 15 is equipped with a spiral component 17, the slope net can be expanded with the help of the spiral component 17 during the rotation of the control shaft 15, so that the slope net unfolds and avoids the problem of wrinkles. In addition, with the cooperation of the extrusion shaft 20, the No. 1 spring 21 limits the extrusion shaft 20, so that the slope net can be stably and dynamically attached to the control shaft 15, ensuring the unfolding effect of the slope net and facilitating the overall laying work.

[0089] Example 3: Based on the dynamic tensioning mechanism provided in Example 1, this example provides a further technical solution for the dynamic tensioning mechanism.

[0090] like Figure 8 and Figure 9 As shown, the dynamic tensioning mechanism includes:

[0091] Two slide grooves 22 are symmetrically opened on the frame 1, and a slide block 23 is slidably engaged in each slide groove 22.

[0092] Two second springs 24 are respectively set in two second slide grooves 22 and connected to the second slider 23;

[0093] Two flexible components are respectively set on two second sliders 23, and a tension roller 25 is rotatably installed between the two flexible components;

[0094] In each embodiment of the present invention, the dynamic tensioning mechanism further includes:

[0095] Two cam components 26 are fixedly sleeved on both ends of the control shaft 15;

[0096] Two contact wheels 27 are mounted on two second sliders 23 via brackets, and each contact wheel 27 contacts the corresponding cam component 26.

[0097] Each flexible component includes:

[0098] The sliding seat 28 is set on the second slider 23. The sliding plate 29 is slidably engaged in the sliding seat 28. The two flexible sliding plates 29 are rotatably connected to both ends of the tension roller 25 respectively.

[0099] Tension spring 30 is disposed between sliding seat 28 and slide plate 29, and tension roller 25 is moved by tension spring 30;

[0100] It is worth noting that when dynamically tensioning the slope net, a dynamic tensioning mechanism is installed. Under normal conditions, the tension spring 30 pushes the slide plate 29 to move within the slide block, while the slope net contacts the tension roller 25. The contact tension spring 30 controls the tension of the slope net, ensuring a smooth contact with the slope. Simultaneously, as the control shaft 15 rotates, the pre-set cam 26 on it follows suit. In a single rotation, the cam 26 contacts the contact wheel 27, forcing the second slider 23 and the tension roller 25 to move further, increasing the movement distance of the tension roller 25. This allows for intermittent tension control during the slope net laying process, dynamically controlling the tension of the slope net, ensuring a good laying condition of the slope net, and improving construction quality.

[0101] Example 4: A method for using netting on steep slopes, which specifically includes the following steps:

[0102] Step 1: First, temporarily store the slope net on the release roller 3. Then, transfer the net hanging device to the waiting area at the top of the slope. After that, fix the steel ropes 5 of the two take-up reels 4 on the frame 1 to the top of the slope.

[0103] Step 2: Then start the drive motor 6 to control the release roller 3 and the slope net on it to release. At the same time, rotate the two take-up reels 4 to release the steel rope 5. When releasing the slope net, the frame 1 moves and walks in the same way to carry out the self-walking slope net laying work.

[0104] Step 3: During operation, the slope net is expanded to both sides using the unfolding mechanism to ensure the flatness of the slope net;

[0105] Step 4: The dynamic tensioning mechanism in operation can control the tension of the slope net, so that the slope net is laid with a certain tension, avoiding the situation of wrinkles in the laid slope net.

[0106] This invention provides a netting device and method for steep slopes. The specific working principle is as follows: First, the slope net is temporarily stored on the release roller 3. Then, the netting device is transferred to the waiting area at the top of the slope. Next, the steel ropes 5 of the two take-up reels 4 on the frame 1 are fixed to the top of the slope to ensure the stability of the frame 1 and subsequent release. Specifically, the netting can be fixed to the slope by ground nails and other locking parts. Then, the slope netting is passed around the unfolding mechanism, the dynamic tensioning mechanism and the two pressing rollers, and the top slope netting is fixed to the top of the slope.

[0107] Then, the drive motor 6 is started to control the release roller 3 and the slope net on it to release. As the release roller 3 rotates, the two take-up reels 4 rotate in conjunction to release the steel rope 5. In this way, the overall position of the frame 1 is moved and traveled synchronously when the release roller 3 releases the slope net, which can automatically travel and fall. The two work together effectively without manual operation. The design of two pressing rollers can stably guide the slope net and synchronously press it, so that the slope net can form effective contact with the soil and improve the hanging effect of the slope net.

[0108] By incorporating an unfolding mechanism, the slope net is expanded to both sides during release, preventing wrinkles and ensuring its flatness. Simultaneously, with the assistance of a dynamic tensioning mechanism, the slope net is tensioned and controlled, allowing it to be laid under tension, preventing wrinkles and improving laying efficiency and cost. After laying, the top steel rope 5 is released, and the drive motor 6 is reversed to rewind the slope net onto the winding roller. The steel rope 5 is then retrieved, and the process can be repeated at the desired slope location.
