Description

Technical Field

[0001] This invention relates to the field of road pothole and cover plate equipment, specifically a road deep pothole control system with an upper cover plate. Background Technology

[0002] In modern transportation systems, roads are critical infrastructure, and their condition directly affects the efficiency and safety of transportation. Potholes are a common road defect, causing numerous negative impacts on traffic and road infrastructure itself.

[0003] When road surfaces are damaged, potholes of various shapes and sizes are formed, posing a significant hazard to transportation. To better simulate the shape, dynamic appearance, and disappearance of potholes, and to assess and test the impact of deep potholes on transportation, a controllable road deep pothole control system needs to be designed. The core of this system lies in precisely controllable flap technology. Summary of the Invention

[0004] This invention aims to dynamically simulate pothole characteristics by programmatically adjusting the movement of road surface covers and changing their shape in real time. It has good concealment and sudden change characteristics, and can achieve rapid switching and reuse, providing a solution for efficiently and realistically reproducing complex road conditions.

[0005] This invention is achieved through the following technical solutions: A road surface deep pothole control system with an upper cover plate mainly includes a cover plate mechanism A, a hoisting mechanism B, a hydraulic control mechanism C, and a steel frame structure D; specifically, it includes a circular cover plate, a truss, irregularly shaped connecting rods; a hoist; U-shaped overlapping fasteners; a steel frame; and hinged supports. The control system is highly adaptable to its surrounding environment, making it challenging to detect.

[0006] The cover plate mechanism A has high strength, ensuring it will not be damaged during vehicle operation. A truss is arranged beneath the road cover plate, forming a distributed structure to distribute the force on the circular cover plate; the irregularly shaped connecting rod is welded to the lower part of the truss, and all three are controlled synchronously as a whole. A load-bearing support is provided at the lower part of the cover plate mechanism A, one side of which is hinged to the steel frame, and the other side is connected to a U-shaped lap fastener fixed to the steel frame. The winch mechanism B connects to the irregularly shaped connecting rod, and guides the cable to lift the cover plate mechanism A via a remote-controlled winch.

[0007] The winch mechanism B consists of a winch and a fixed pulley. The winch is connected to a special-shaped connecting rod to realize the lifting function of the cover plate mechanism A. After the winch lifts the cover plate mechanism A to a specified height, the winch starts to idle and disconnects the control of the cover plate mechanism A.

[0008] The hydraulic control mechanism C consists of a hydraulic cylinder and a U-shaped overlapping fastener. The U-shaped overlapping fastener is arranged on the upper crossbeam of the steel frame, and its extension and retraction are controlled by the hydraulic cylinder. When the cover plate mechanism A is rolled up to the designated position, the U-shaped overlapping fastener extends to form an overlapping platform for placing the cover plate mechanism A. The potholes in the road surface are closed by the upper cover plate mechanism A, forming a complete road surface.

[0009] When the U-shaped overlapping fastener extends, the lower winch mechanism B switches to idle mode, and the cover plate mechanism A is not subject to traction. After the U-shaped overlapping fastener retracts, the cover plate mechanism A becomes unbalanced and quickly flips downward, achieving the effect of rapidly generating deep pits on the road surface.

[0010] The irregularly shaped connecting rod has a welded pull ring at its bottom and is connected to a cable. It is controlled by a winch via a fixed pulley to achieve the lifting of the cover plate mechanism A. In the lifting mechanism, the irregularly shaped connecting rod, cable, fixed pulley, and winch are on the same longitudinal plane. In the winch mechanism B, the fixed pulley is arranged below the U-shaped overlapping fastener, and the winch is placed directly below the fixed pulley.

[0011] When the winch mechanism B pulls up the cover plate mechanism A, the U-shaped overlapping fastener extends, and the cover plate mechanism A rests on top of it, forming an effective connection. After this connection, the upper surfaces of the cover plate mechanism A and the steel frame structure D are flush with the ground. At this point, the cover plate mechanism A is raised to its limit, the winch idles, and the cable disconnects from the control of the irregular connecting rod. The U-shaped overlapping fastener is retracted, and the overlapping end of the cover plate loses support and detaches, thus quickly creating a deep pit in the road.

[0012] At the connection between the cover plate mechanism A and the U-shaped overlapping fastener, wear-resistant and shock-absorbing pads are provided; steel tie rods are welded between the steel frames to ensure structural stability; the bottom of the steel frame structure D is equipped with a foundation and buried underground, and both the interior and exterior of the structure are waterproofed and moisture-proofed.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments, but it should not be construed as the scope of the present invention being limited to the following embodiments. The structural descriptions in the following text with reference to the accompanying drawings are intended to illustrate and facilitate understanding of this description. The dimensional annotations of the components in the text are only examples in a complete system. Various substitutions and modifications made based on ordinary technical knowledge and common practices in the art without departing from the above-described technical concept of the present invention should be included within the protection scope of the present invention.

[0015] like Figure 1 As shown, the cover plate mechanism A in this invention comprises three types of components, including an upper circular cover plate A1, a middle truss A2, and a lower irregular connecting rod A3.

[0016] In this example, the circular cover plate A1 on the upper part of the road surface is made of UHPC composite plate with a diameter of 2m. The composite plate is 20mm thick and consists of two layers: an upper UHPC plate with a thickness of 15mm and a lower Q235 steel plate with a thickness of 5mm. The upper part of the thin steel plate has uniform protrusions, and pre-installed connectors are provided to overlap with the upper cast-in-place UHPC plate to generate mechanical interlocking force.

[0017] In this example, the central truss A2 serves as a distribution structure responsible for distributing the upper load. It is made of Q345 steel, and the overall dimensions of truss A2 are 1600×1030×90mm. The cross-sectional dimensions of the members are 20×10mm for horizontal members and 20×30mm for vertical members. Detailed dimensions are as follows... Figure 2 As shown.

[0018] The dimensions of the irregular connecting rod A3 at the bottom of the cover plate mechanism A are determined based on the space under the steel frame D1 after the cover plate is flipped. In this example, the irregular connecting rod A3 is made of Q345 steel, with a span of 1600mm, a height of approximately 432mm, and a width of 70mm.

[0019] The cover plate mechanism A is connected to the steel frame D1 via hinge support D201. Figure 3 This is a schematic diagram of hinge support D201. The hinge support D201 has design dimensions of 120×120×96mm and a support plate thickness of 8mm. After positioning, hinge support D201 is welded to the upper crossbeam of steel frame D2.

[0020] In this invention, the hoisting mechanism B includes a winch B1 and a fixed pulley.

[0021] Based on the stress calculations for cover plate mechanism A, the hoisting mechanism B uses a commercially available PA600 electric remote-controlled winch B1 as the hoisting device, fixed in the middle of the steel frame D1. A pulley is installed at the bottom of the upper beam, and the cable pulls the lifting ring on the irregular connecting rod A3 to lift the cover plate mechanism A. When the cover plate is hoisted to the designated position, the winch B1 starts to idle under control, and the control is disconnected.

[0022] Figure 5 The diagram shows a U-shaped overlapping fastener C1 in the hydraulic control system. The fastener contains a HOB heavy-duty hydraulic cylinder, controlled by the hydraulic system to achieve the expansion and contraction of the overlapping joint. The U-shaped overlapping fastener C1 is bolted to the middle of the steel frame D1 crossbeam, and a slide rail is installed below it. The U-shaped overlapping fastener has dimensions of 200×60×100mm and is made of Q345 steel.

[0023] After the hoisting mechanism B raises the cover plate mechanism A to the designated position, the overlapping joint extends and overlaps with the end of the cover plate mechanism A, such as... Figure 6 As shown, the pothole in the road surface has reached a closed state. During the process of the pothole being formed, the hydraulic cylinder controls the U-shaped overlapping fastener to retract, and the upper cover plate mechanism A loses its support and begins to fall freely under its own weight, forming the pothole in the road surface.

[0024] In this invention, the steel frame structure D is constructed by longitudinally and transversely welding Q235 square steel pipes. The square steel section has dimensions of 300×300mm and a wall thickness of 10mm. The steel frame D1 is 1.5m high, 2m wide on one side, and the distance between the two steel frames is 2m, for placing and fixing the road cover plate mechanism A.
