Description

Technical Field

[0001] This utility model relates to the field of protective device technology, specifically to a road slope anti-collapse safety protection device. Background Technology

[0002] Slope collapse prevention safety protection devices are safety systems specifically designed to protect roadside slopes created through excavation. They aim to prevent soil erosion by rainwater, which could lead to slope collapse. These devices are typically made of high-strength materials and include components such as anchoring systems, drainage facilities, and reinforcing mesh. They effectively distribute soil pressure and enhance slope stability. Through scientific layout and installation, these devices can significantly improve the long-term safety of roadside slopes, reduce the impact of natural disasters on traffic, and ensure the safety of vehicles and pedestrians. They are an indispensable safety measure in modern road construction.

[0003] Chinese patent CN214194567U discloses a retaining structure for foundation pits, comprising a retaining plate, multiple extension plates mounted on the retaining plate, and a connecting assembly for connecting the retaining plate and the extension plates. The retaining plate is fixedly installed in the foundation pit and arranged along the perimeter of the pit. The extension plates are adapted to the retaining plate and can move along the retaining plate, and are detachably connected to the retaining plate through the connecting assembly. This retaining structure for foundation pits reduces the risk of collapse due to unmanaged soil piles outside the sheet piles during construction, which can easily occur due to rain or excessively high soil piles.

[0004] The retaining structure for foundation pits described in the aforementioned patent documents consists of multiple sets of base plates combined together, with an extendable plate at the top of the base plates, allowing for adjustment of the overall height of the retaining structure. A support frame is then inclined on one side of the extendable plate to support it. Existing support frames only allow adjustment of the extendable plate's height by adjusting the tilt angle. In actual use, the weight of the soil and rocks acts directly on the center of the retaining structure, causing deformation or even fracture due to pressure from the soil and rocks. Therefore, a road slope collapse prevention safety protection device is proposed. Utility Model Content

[0005] To address the aforementioned problems, a road slope collapse prevention safety protection device is provided. The device utilizes the rotation of a lead screw to drive a longitudinally moving frame, allowing the frame to adjust its support position on the modular retaining wall according to actual usage requirements. A support mechanism is hinged to one side of the base, enabling not only adjustment based on the frame's position but also effective support. This solves the problem of modular retaining walls easily bending, deforming, or even being damaged by soil and rock impacts.

[0006] To address the existing technical problems, this application provides a road slope anti-collapse safety protection device, including a base, a frame disposed on the upper surface of one side of the base, a combined retaining plate disposed inside the frame for retaining soil, a movable frame disposed inside the frame that can move longitudinally, and a support mechanism disposed on one side of the base for supporting the movable frame. The support mechanism includes an installation tube with its bottom hinged to the side of the base away from the frame, and a retractable rod that can move along its central axis is installed inside the installation tube. The extension end of the retractable rod is hinged to the movable frame.

[0007] The outer surface of the mounting tube away from the base is provided with a tightening block for clamping the retractable rod;

[0008] The end of the mounting tube furthest from the base is fitted with a tightening nut that can engage with the threaded tightening block;

[0009] The upright frame is also equipped with a lead screw installed longitudinally inside for driving the moving frame to move longitudinally, and the moving frame is threadedly connected to the lead screw.

[0010] As one technical solution of this application, the inner side of the upright is symmetrically provided with sliding grooves for limiting the position; the two ends of the movable frame are symmetrically provided with sliders that can slide and cooperate with the sliding grooves.

[0011] As a technical solution of this application, the upper end face of the base away from the support frame is provided with a number of longitudinally arranged columns, and the columns are provided with threaded holes in the longitudinal direction.

[0012] The threaded hole is equipped with a threaded rod that can position the base. The threaded rod is threadedly connected to the threaded hole and can move longitudinally along the central axis of the threaded hole.

[0013] As a technical solution of this application, a fixing plate capable of fixing the top of the combined retaining plate is horizontally provided on one side of the top of the support frame, and threaded rods are symmetrically provided on the side of the fixing plate near the support frame.

[0014] The top of the support frame is horizontally provided with a number of mounting seats corresponding to the number of threaded rods on the side away from the fixed plate, and the threaded rods are movably disposed inside the mounting seats;

[0015] The mounting base is provided with a rotating nut that can rotate around the central axis of the mounting base at one end away from the upright. The threaded rod can pass through the rotating nut and can be threadedly connected to the rotating nut.

[0016] As one technical solution of this application, the bottom of the base is provided with a slot on the side near the upright for fixing and limiting the bottom of the combined retaining plate, and the bottom of the combined retaining plate is inserted into the slot.

[0017] As one technical solution of this application, the mobile frame is provided with a longitudinal clearance groove for installing the combined retaining plate.

[0018] As one technical solution of this application, a fixing frame is installed longitudinally on one side of the column, and a remote monitoring controller capable of sharing data with an external monitoring center is installed longitudinally inside the fixing frame. Several water level monitoring sensors for monitoring water level are arranged longitudinally and equidistantly on one side of the remote monitoring controller.

[0019] As one technical solution of this application, a mounting plate is longitudinally arranged on the outer side of the base adjacent to the fixing frame, and a grid is installed inside the mounting plate.

[0020] The advantages of this utility model compared to the prior art are:

[0021] This application utilizes the rotation of a lead screw to drive the longitudinal movement of a movable frame, enabling the movable frame to adjust its support position on the combined retaining wall according to actual usage requirements. An installation pipe is hinged to one side of the base, and a retraction rod is installed at one end of the installation pipe. A tightening nut is installed at the end of the tightening block near the retraction rod, allowing the tightening nut to fix the retraction rod via the tightening block. This ensures that the support mechanism can not only be adjusted according to the position of the movable frame but also effectively support the movable frame, solving the problem of the combined retaining wall easily bending, deforming, or even being damaged when subjected to soil and rock impacts.

Detailed Implementation

[0029] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0030] See Figures 1-6 As shown, a road slope anti-collapse safety protection device includes a base 2, a frame 1 set on the upper surface of one side of the base 2, a combined retaining plate 3 set inside the frame 1 for retaining soil, a movable frame 17 set inside the frame 1 that can move longitudinally, and a support mechanism 4 set on one side of the base 2 for supporting the movable frame 17. The support mechanism 4 includes an installation tube 41 with its bottom hinged to the side of the base 2 away from the frame 1. A retractable rod 44 that can move along its central axis is installed inside the installation tube 41. The extended end of the retractable rod 44 is hinged to the movable frame 17.

[0031] A tightening block 42 for clamping the retractable rod 44 is provided on the outer surface of the mounting tube 41 away from the base 2;

[0032] A tightening nut 43 that can engage with the threaded tightening block 42 is installed at the end of the mounting tube 41 away from the base 2;

[0033] The interior of the upright frame 1 is also longitudinally installed with a lead screw 16 for driving the moving frame 17 to move longitudinally, and the moving frame 17 is threadedly connected to the lead screw 16.

[0034] A drive motor 15 for driving the lead screw 16 to rotate is also installed on the top of the support frame 1. The top end of the lead screw 16 is fixedly connected to the output end of the drive motor 15. When the drive motor 15 starts, the output end of the drive motor 15 can drive the lead screw 16 to rotate synchronously. At this time, the rotation of the lead screw 16 will drive the movable frame 17 connected to its external thread to move longitudinally. At the same time, the movable frame 17 can drive the top of the retractable rod 44 hinged on one side to move longitudinally synchronously. When the top of the retractable rod 44 moves, the end of the retractable rod 44 away from the movable frame 17 can move along the central axis of the mounting tube 41, so that the overall length of the support mechanism 4 can be adjusted synchronously according to the position change of the movable frame 17, thereby making the support mechanism 4 more applicable. Then, by rotating the tightening nut 43, the tightening nut 43 can engage with the tightening block 42 threadedly, and at the same time, the tightening nut 43 can move along the central axis of the mounting tube 41. When the tightening nut 43 rotates and gradually approaches the retracting rod 44, it will gradually tighten the tightening block 42, so that the inner wall of the tightening block 42 can make close contact with the outer surface of the retracting rod 44, thereby fixing the retracting rod 44 and preventing the retracting rod 44 from loosening when supporting the moving frame 17, thus making the support strength of the support mechanism 4 better.

[0035] See Figure 3 As shown, the inner side of the upright frame 1 is symmetrically provided with sliding grooves 11 for limiting the position; the two ends of the movable frame 17 are symmetrically provided with sliders 172 that can slide and cooperate with the sliding grooves 11.

[0036] To ensure the stability of the movable frame 17, sliders 172 that can slide and engage with the slide groove 11 are respectively provided at both ends of the movable frame 17. When the lead screw 16 drives the movable frame 17 to move longitudinally, the movable frame 17 slides along the inside of the slide groove 11 through the sliders 172, preventing the movable frame 17 from rotating while moving, thus effectively ensuring the stability of the movable frame 17.

[0037] See Figure 3 and Figure 6 As shown, on the upper end of the base 2 away from the support frame 1, there are several longitudinally arranged columns 22, and the inside of the columns 22 is provided with threaded holes 221.

[0038] A threaded rod 25 capable of positioning the base 2 is installed inside the threaded hole 221. The threaded rod 25 is threadedly connected to the threaded hole 221 and can move longitudinally along the central axis of the threaded hole 221.

[0039] To ensure the stability of the base 2, a threaded rod 25 is installed inside the threaded hole 221. When the threaded rod 25 is rotated, it moves longitudinally along the central axis of the threaded hole 221. When the threaded rod 25 moves downward, its bottom end can insert into the foundation, thereby fixing the base 2. This effectively prevents the combined retaining plate 3 from pushing the support frame 1 and the base 2 when it is squeezed by soil, thus effectively ensuring the stability of the base 2.

[0040] See Figure 1 , Figure 3 and Figure 5 As shown, a fixing plate 14 is horizontally provided on one side of the top of the frame 1, which can fix the top of the combined retaining plate 3. Threaded rods 142 are symmetrically provided on the side of the fixing plate 14 near the frame 1.

[0041] The top of the support frame 1 is horizontally provided with a number of mounting seats 18 corresponding to the number of threaded rods 142 on the side away from the fixed plate 14, and the threaded rods 142 are movably disposed inside the mounting seats 18;

[0042] The mounting base 18 is provided with a rotating nut 181 that can rotate around the central axis of the mounting base 18 at one end away from the upright 1. A threaded rod 142 can pass through the rotating nut 181 and can be threadedly connected to the rotating nut 181.

[0043] To ensure the stability of the top of the combined retaining wall 3, a threaded rod 142 is installed inside the mounting base 18, and a rotating nut 181 is rotatably installed at one end of the mounting base 18. The threaded rod 142 is then inserted into the center of the rotating nut 181. When the rotating nut 181 rotates, it drives the threaded rod 142 to move horizontally. Simultaneously, the threaded rod 142 moves the fixing plate 14 closer to or away from the support frame 1. When the fixing plate 14 approaches the support frame 1, it gradually applies a clamping force to the combined retaining wall 3, causing the fixing plate 14 and the support frame 1 to cooperate in clamping the top of the combined retaining wall 3, preventing misalignment at the joint of the top of the combined retaining wall 3, and effectively ensuring the stability of the top of the combined retaining wall 3.

[0044] See Figure 3 As shown, a slot 13 is longitudinally provided on the bottom of the base 2 near the side of the upright 1 for fixing and limiting the bottom of the combined retaining plate 3, and the bottom of the combined retaining plate 3 is inserted into the slot 13.

[0045] By inserting the bottom of the combined retaining plate 3 into the slot 13, the combined retaining plate 3 can be inserted downward into the soil along the central axis of the slot 13 during installation. This ensures that the combined retaining plate 3 can descend vertically when inserted into the soil, effectively preventing the combined retaining plate 3 from tilting.

[0046] See Figure 3 As shown, the mobile frame 17 has a longitudinally provided clearance groove 171 for installing the combined retaining plate 3.

[0047] By providing a clearance groove 171 longitudinally on the mobile frame 17, when the mobile frame 17 moves longitudinally, it moves longitudinally along the outside of the combined retaining plate 3 through the clearance groove 171, thereby ensuring that the mobile frame 17 can move longitudinally without being obstructed.

[0048] See Figure 6 As shown, a fixing frame 24 is installed longitudinally on one side of the column 22. A remote monitoring controller 241 capable of sharing data with an external monitoring center is installed longitudinally inside the fixing frame 24. Several water level monitoring sensors 242 for monitoring water level are arranged longitudinally and equidistantly on one side of the remote monitoring controller 241.

[0049] The remote monitoring controller 241 is preferably a Siemens S7-1500 or a Schneider M340. The remote monitoring controller 241 is installed inside the mounting bracket 24, which is fixed to one side of the base 2. Several water level monitoring sensors 242 are equidistantly arranged on one side of the remote monitoring controller 241. When the water level reaches the corresponding water level monitoring sensor 242, the sensor transmits the data to the remote monitoring controller 241, which then remotely transmits the information to an external monitoring center. This allows the external monitoring center to effectively monitor water level changes in real time, ensuring that the high-protection device can monitor the water level and effectively reduce the risk of disasters.

[0050] See Figure 6 As shown, a mounting plate 222 is longitudinally arranged on the side of the base 2 adjacent to the fixing frame 24, and a grille 23 is installed inside the mounting plate 222.

[0051] By installing the grating 23 inside the mounting plate 222, the grating 23 can eliminate the impact of water waves, effectively preventing the combined retaining plate 3 from being damaged due to structural fatigue under repeated water flow impact.
