Technical Field

[0001] This utility model relates to the field of slope anti-skid technology, and in particular to a highway subgrade slope anti-skid device. Background Technology

[0002] With the rapid development of highway construction, landslides on roadbed slopes have become a serious threat to road safety.

[0003] Chinese Patent Publication No. CN217399463U discloses a highway subgrade slope anti-skid device, including a subgrade body. Two mounting plates are symmetrically arranged on the upper surface of the subgrade body, and both mounting plates are detachably connected to the subgrade body via first bolts. Mounting rods are connected to the upper surfaces of both mounting plates. A mounting frame is detachably connected to the rear side wall of the mounting rod via second bolts, and a protective net is installed inside the mounting frame. Protective blocks are installed on the slope of the subgrade body via first fixing bolts. A set of clamping plates is evenly spaced on the lower side of the protective blocks, and the clamping plates are detachably connected to the subgrade body via second fixing bolts. This utility model, through the mounting frame and protective net, can intercept falling rocks, preventing them from sliding onto the road surface and improving safety performance. The third bolts facilitate the replacement of damaged protective nets, allowing for continuous use. Furthermore, the reinforcing frame increases strength, further improving safety performance.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: some existing highway subgrade slope anti-skid devices have only one protective function, which is not only insufficient to protect against the impact of gravel, but also insufficient to protect the bottom of the slope. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of insufficient protection of highway subgrade slope anti-skid devices. Therefore, we propose a highway subgrade slope anti-skid device with good protection.

[0006] To achieve the above objectives, this application adopts the following technical solution: a roadbed slope anti-skid device, comprising: a roadbed slope body, and an installation plate installed on the upper surface of the roadbed slope body by anti-loosening screws, an inclined plate welded to one side of the installation plate, the inclined plate being fixed to the slope surface of the roadbed slope body by screws and anti-loosening screws, a bottom plate welded to one end of the inclined plate, the bottom of the bottom plate being fixed to the bottom of the slope of the roadbed slope body by anti-loosening screws, and an anti-skid component for increasing protection being provided on one side of the roadbed slope body;

[0007] The anti-slip assembly includes a connecting plate fixedly mounted on the upper surface of the mounting plate, and a protective plate hinged to the upper surface of the connecting plate via a hinge shaft. A spring telescopic rod is hinged to the upper surface of the connecting plate, and the telescopic end of the spring telescopic rod is hinged to one side of the protective plate. A support rod is fixedly mounted on the upper surface of the mounting plate, and a damping spring is provided between the support rod and the protective plate. A buffer plate is hinged to one side of the base plate via a reset hinge. There are two sets of buffer plates, and one side of each set of buffer plates extends out of the base plate.

[0008] Preferably, each set of buffer plates has a rubber pad on its outer surface.

[0009] Preferably, the outer surface of the protective plate is riveted with an aluminum alloy mesh frame arranged in a mesh pattern.

[0010] Preferably, a limit block is provided on the upper surface of the connecting plate.

[0011] Preferably, the outer surfaces of the mounting plate, the inclined plate, and the base plate are all coated with a graphene composite coating.

[0012] Preferably, one side of the inclined plate is provided with crisscrossing guide channels, and the end of the guide channels is connected to the drainage ditch inside the roadbed slope body.

[0013] Preferably, a maintenance ladder is fixed to one side of the inclined plate by screws.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] In this invention, the device is fixed to the mounting plate via a connecting plate, and the protective plate is hinged to the connecting plate via a hinge shaft. Therefore, when soil and rock fall on the slope, the spring telescopic rod absorbs part of the impact force. At the same time, the damping spring can further reduce the swaying of the protective plate. After the impact force weakens, the damping spring, relying on its own elastic restoring force, pushes the protective plate to rotate around the hinge shaft to reset, returning it to the initial protective position to cope with the next possible impact. In addition, the two sets of buffer plates located at the bottom of the slope, which are hinged by a reset hinge, can further buffer the remaining impact. After being subjected to force, the buffer plates automatically reset with the help of the reset hinge, and can continuously play a protective role. Attached Figure Description

[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Reference Figure 1 As shown, this utility model provides a technical solution: a roadbed slope anti-skid device, comprising: a roadbed slope body 1, and an installation plate 2 installed on the upper surface of the roadbed slope body 1 by anti-loosening screws. An inclined plate 3 is welded to one side of the installation plate 2. The inclined plate 3 is fixed to the slope surface of the roadbed slope body 1 by anti-loosening screws. A bottom plate 4 is welded to one end of the inclined plate 3. The bottom of the bottom plate 4 is fixed to the bottom of the slope of the roadbed slope body 1 by anti-loosening screws. An anti-skid component 5 for increasing protection is provided on one side of the roadbed slope body 1.

[0024] Reference Figures 1-4As shown in this embodiment: the anti-slip component 5 includes a connecting plate 51 fixedly installed on the upper surface of the mounting plate 2, and a protective plate 52 hinged to the upper surface of the connecting plate 51 via a hinge shaft. A spring telescopic rod 53 is hinged to the upper surface of the connecting plate 51, and the telescopic end of the spring telescopic rod 53 is hinged to one side of the protective plate 52. A support rod 54 is fixedly installed on the upper surface of the mounting plate 2, and a damping spring 55 is provided between the support rod 54 and the protective plate 52. A buffer plate 56 is hinged to one side of the base plate 4 via a reset hinge. Two sets of buffer plates 56 are provided, and one side of each set of buffer plates 56 extends out of the base plate 4. Since the connecting plate 51 is fixed on the mounting plate 2... The protective plate 52 is hinged to the connecting plate 51 via a hinge shaft. Therefore, when the slope is impacted by falling rocks, the spring telescopic rod 53 absorbs part of the impact force. At the same time, the damping spring 55 can further reduce the swaying of the protective plate 52. After the impact force weakens, the damping spring 55 uses its own elastic restoring force to push the protective plate 52 to rotate around the hinge shaft and reset, so that it returns to the initial protective position to cope with the next possible impact. In addition, the two sets of buffer plates 56 located at the bottom of the slope and hinged to each other via a reset hinge can further buffer the remaining impact. After being subjected to force, the buffer plates 56 automatically reset with the help of the reset hinge, so as to continuously play a protective role.

[0025] Each set of buffer plates 56 has a rubber pad 57 on its outer surface to increase the ability to absorb impact force, thereby reducing rigid damage caused by impact.

[0026] The outer surface of the protective plate 52 is riveted with an aluminum alloy mesh frame 58 in a mesh pattern, which can disperse the impact force.

[0027] A limit block 59 is provided on the upper surface of the connecting plate 51 to prevent the protective plate 52 from rotating excessively, so that it can remain vertical in a static state.

[0028] The outer surfaces of mounting plate 2, inclined plate 3, and base plate 4 are all coated with graphene composite coating, which increases corrosion resistance and extends service life.

[0029] One side of the inclined plate 3 is provided with crisscrossing guide channels 31. The end of the guide channel 31 is connected to the drainage ditch inside the roadbed slope body 1, guiding the rainwater on the slope to collect into the drainage ditch inside the slope, so that it can be discharged quickly and avoid softening the slope soil.

[0030] A maintenance ladder 6 is fixedly installed on one side of the inclined plate 3 with screws, which facilitates later maintenance and inspection. The steps on the maintenance ladder 6 are provided with anti-slip texture.

[0031] Working principle: Mounting plate 2, inclined plate 3, and base plate 4 are all fixed to the roadbed slope body 1 with anti-loosening screws, forming a stable support, thereby effectively dispersing and resisting the sliding force of the slope soil. Furthermore, since the outer surfaces of mounting plate 2, inclined plate 3, and base plate 4 are all coated with graphene composite coating, corrosion resistance is increased, extending service life. Because connecting plate 51 is fixed to mounting plate 2, and protective plate 52 is hinged to connecting plate 51 via a hinge shaft, when soil and rock fall impacts the slope, spring extension rod 53 absorbs part of the impact force. Simultaneously, damping spring 55 further reduces the swaying of protective plate 52, reducing the impact damage to the structure. After the impact force weakens, the damping spring... 55 relies on its own elastic restoring force to push the protective plate 52 to rotate around the hinge axis and reset it, so that it returns to the initial protective position in order to cope with the next possible impact. In addition, the two sets of buffer plates 56, which are located at the bottom of the slope and are hinged by the reset hinge, and combined with the rubber pad 57 on their outer surface, can further buffer the remaining impact. After being subjected to force, the buffer plate 56 automatically resets with the help of the reset hinge, and can continue to play a protective role. Since the outer surface of the protective plate 52 is provided with an aluminum alloy mesh frame 58, it can disperse the impact force and enhance the protective effect. In addition, since the upper surface of the connecting plate 51 is provided with a limit block 59, it can prevent the protective plate 52 from rotating excessively, so that it can maintain a vertical state in a static state. In addition, since the inclined plate 3 has crisscrossing diversion channels 31 on one side, and the end of the diversion channel 31 is connected to the drainage ditch inside the roadbed slope body 1, rainwater on the slope can be guided to collect into the drainage ditch inside the slope, so that it can be discharged quickly and avoid softening the slope soil. Furthermore, since the inclined plate 3 has a maintenance ladder 6 fixedly installed on one side by screws, it is convenient for later maintenance and inspection. The steps on the maintenance ladder 6 are provided with anti-slip texture.

[0032] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
