Description

Technical Field

[0001] This utility model relates to the field of roadbed technology, specifically to a roadbed slope protection device. Background Technology

[0002] Slopes are prone to collapse due to long-term erosion by rainwater, weathering, and gravity. Roadbed slope protection devices are important engineering facilities to prevent slope soil slippage and erosion. They are widely used in the construction of infrastructure such as highways and railways. By stabilizing the surface soil, they effectively reduce soil erosion and ensure the stability of the roadbed and driving safety.

[0003] Traditional roadbed slope protection often uses metal mesh protective netting. During installation, the metal mesh protective netting is laid on the slope surface, relying on the mesh structure to disperse stress and prevent rockfall.

[0004] However, existing roadbed slope protection devices have certain limitations in use. Because the protective netting is laid directly on the slope surface and in close contact with it, it is easy to roll up pollutants such as mud, sand, and fallen leaves from the slope surface during the retraction process. This results in the storage space of the protective netting being occupied by a large amount of impurities, affecting the cleanliness and efficiency of the device. Moreover, these pollutants, if attached for a long time, can corrode the protective netting, reducing its service life and affecting its subsequent use. In addition, traditional metal mesh protective netting is mostly a single piece of structure, which cannot be adaptively adjusted according to changes in slope geological conditions, lacking flexibility in use. Therefore, a roadbed slope protection device is proposed to solve the above problems. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a roadbed slope protection device that effectively solves the problems of existing protective nets, which, during the retraction process, engulf the slope surface with pollutants such as mud, sand, and fallen leaves, resulting in the storage space of the protective net being occupied by a large amount of impurities, affecting the cleanliness and efficiency of the device. Moreover, these pollutants, if attached for a long time, can corrode the protective net, reducing its service life and affecting its subsequent use. Furthermore, traditional metal mesh protective nets are mostly monolithic structures, unable to adapt to changes in slope geological conditions, and lacking flexibility in use.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] See attached document Figure 1-9 A roadbed slope protection device, comprising: The protective net 1 serves to prevent slope soil slippage and rockfall. A first support rod 2 and a second support rod 3 are respectively installed at both ends of the protective net 1. The first support rod 2 is fixedly connected to one end of the protective net 1, providing fixed support for one end of the net 1 and ensuring stable installation of the net 1 on the slope. The outer wall of the second support rod 3 has a transmission port 301, and the protective net 1 is movably installed in the inner cavity of the second support rod 3 through a winding structure. This not only provides support for the other end of the net 1 but also accommodates the winding structure and other components. Through the fixation of the two support rods, the protective net 1 is stably laid on the slope surface, fulfilling its protective function. A cleaning component is installed on the outer wall of the second support rod 3, which includes: The movable groove 302 formed on the outer wall of the second support rod 3 provides space for the rotation of the connecting rod 501; The striking block 5 is fixedly connected to the connecting rod 501. The connecting rod 501 is rotatably connected to the moving groove 302 through a pin. The moving of the connecting rod 501 drives the striking block 5 to move, so that the striking block 5 continuously collides with the protective net 1, thereby causing the dust and debris on the protective net 1 to fall off, thus playing the role of cleaning the protective net 1.

[0021] The winding structure includes a rotating shaft 4 and a winding drum 401. The rotating shaft 4 is rotatably connected in the inner cavity of the second support rod 3, and the winding drum 401 is fixedly installed on the outer wall of the rotating shaft 4. The other end of the protective net 1 is fixedly connected to the outer wall of the rotating shaft 4 by bolts. In use, the rotating shaft 4 is rotated to drive the winding drum 401 to rotate, thereby realizing the winding and unwinding of the protective net 1.

[0022] A connecting plate 503 is fixedly installed on the outer wall of the rotating shaft 4, and a sliding block 504 is fixedly installed at the bottom of the connecting plate 503. A transverse sliding groove 502 is opened through the outer wall of the connecting rod 501, and the sliding block 504 is movably engaged in the sliding groove 502. In use, the rotating shaft 4 drives the connecting plate 503 to rotate, which in turn drives the sliding block 504 to rotate. The connecting plate 503 rotates with the rotating shaft 4, and the sliding block 504 moves in the sliding groove 502 of the connecting rod 501, forcing the connecting rod 501 to rotate around the pin, thereby driving the beating block 5 to beat the protective net 1, causing dust and debris to fall off the protective net 1.

[0023] A worm gear 402 is fixedly installed on the outer wall of the rotating shaft 4, and a worm 403 is rotatably connected to the inner cavity of the second support rod 3. The worm gear 402 and the outer wall of the worm 403 are meshed and connected. The worm gear 402 and the worm 403 play a transmission role, which smoothly transmits the rotation of the adjusting handle 404 to the rotating shaft 4, promoting the stability of the protective net 1 after it is retracted or extended.

[0024] An adjusting handle 404 is movably inserted into the outer wall of the second support rod 3, and the adjusting handle 404 is fixedly connected to the worm gear 403, allowing the operator to manually rotate the worm gear 403 to adjust the winding and unfolding of the protective net 1. A positioning plate 405 is fixedly installed on the outer wall of the adjusting handle 404, and a circular hole is opened through the outer wall of the positioning plate 405. The positioning plate 405 has 6 evenly distributed circular holes, which cooperate with the positioning screw holes 303 to achieve precise positioning in 60° increments. A positioning screw is movably inserted into the inner wall of the circular hole. The second support rod 3 has a positioning screw hole 303 on its outer wall, and the positioning screw is threaded into the positioning screw hole 303. After adjustment, the positioning screw is inserted into the circular hole of the positioning plate 405 and screwed into the positioning screw hole 303 to fix the position of the adjusting handle 404 and the worm gear 403.

[0025] A fixing plate 6 is fixedly installed on the outer wall of the second support rod 3, and a conveying roller 601 is rotatably connected to the front end of the fixing plate 6 via a rotating shaft. The conveying roller 601 is provided in three sets for conveying the protective net 1, reducing the friction between the protective net 1 and the second support rod 3, making the winding and unfolding of the protective net 1 smoother, and also providing support when the protective net 1 is patted.

[0026] The base 201 is rotatably connected to the bottom of the first support rod 2 via a pin, providing stable support for the first support rod 2 and firmly fixing the first support rod 2 to the slope. At the same time, the pin is rotatably connected to the first support rod 2, allowing the first support rod 2 to be adjusted at a certain angle according to the slope, thereby improving the adaptability of the device.

[0027] The inner wall of the moving groove 302 has a groove, and a compression spring 701 is fixedly installed on the inner wall of the groove. A dustproof plate 7 is fixedly installed on the other end of the compression spring 701. In its natural state, the compression spring 701 pushes the dustproof plate 7 to move towards the connecting rod 501. There are two sets of compression springs 701 and dustproof plates 7, which are symmetrically distributed. The pushing force of the compression spring 701 pushes the dustproof plate 7 to move towards the connecting rod 501, so that the dustproof plate 7 is tightly pressed against the outer wall of the connecting rod 501, which can effectively block the moving groove 302 and prevent dust and other impurities from entering the inner cavity of the moving groove 302 and affecting the movement of the sliding block 504.

[0028] Working principle: During use, the user rotates the adjustment handle 404, causing the worm gear 403 to rotate synchronously. The rotating worm gear 403 drives the worm wheel 402 to rotate, which in turn drives the rotating shaft 4 to rotate. The rotating shaft 4 then drives the take-up drum 401 to rotate, pulling the protective net 1. The protective net 1 enters the inner cavity of the second support rod 3 through the transmission port 301 and winds onto the surface of the take-up drum 401. During the movement of the protective net 1, the rotating shaft 4 rotates, and the connecting disc 503 fixed on its outer wall drives the sliding block 504 to make a circular motion. The sliding block 504 slides in the transverse sliding groove 502 of the connecting rod 501, forcing the connecting rod 501 to swing back and forth around the pin. The beating block 5, which is fixed to the connecting rod 501, then produces a periodic beating action, which beats the protective net 1, effectively shaking off the mud and sand on the surface of the protective net 1 and promoting the cleaning of the protective net 1.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
