Description

Technical Field

[0001] This utility model relates to the field of road barrier machine technology, and in particular to a folding hydraulic road barrier machine. Background Technology

[0002] A road barrier system (or vehicle access control barrier) is a retractable, movable, or deployable physical barrier device primarily used to control vehicle traffic and enhance area security. Unlike fixed road bollards or speed bumps, it can quickly change its state (raise / lower, deploy / retract) as needed, thus achieving flexible and dynamic traffic control and safety management. The main functions of a road barrier system include: ① Vehicle traffic control: When lowered or retracted, the road surface is flat, allowing vehicles to pass normally; when raised or deployed, it forms a solid physical barrier, forcibly preventing unauthorized vehicles from entering or passing through a specific area; it can be integrated with license plate recognition, card swiping, and remote control systems to allow only authorized vehicles to pass. ② Security and Deterrence: Its main function is to resist malicious or accidental collisions with vehicles (such as anti-terrorism, anti-robbery, and prevention of intrusion into important facilities). High-level roadblocks can withstand the violent impact of high-speed vehicles, protecting personnel, buildings, facilities, or sensitive areas behind them; when needed, they can quickly form physical barriers to delineate safe or restricted areas; the visible roadblocks themselves are a powerful deterrent to potential illegal intruders. Common types of roadblocks include: Lifting roadblocks, where the main structure is buried underground and the column or platform rises from the ground to form an obstacle; Flip-up roadblocks, where a sturdy metal plate is connected to the base via hinges, and during operation, a hydraulic cylinder or motor drives the flip-up plate from a horizontal (allowing passage) state to a vertical or tilted (blocking) state. The structure is relatively simple, and the obstacle height is obvious when raised, providing strong visual deterrence; Spike / Tire-puncturing roadblocks, usually hidden under the road surface, where a row of sharp steel spikes or blades pops out at a certain angle when raised, specifically designed to puncture the tires of vehicles that forcibly enter, quickly paralyzing them, but usually not causing more dangerous situations such as vehicle rollover; and Mobile roadblocks, which do not require pre-installation and can be temporarily deployed and moved, such as heavy-duty crash barriers and pushable concrete barriers. They offer high flexibility but usually require manual operation and have a slower response time than automatic lifting roadblocks.

[0003] However, existing roadblock machines have technical problems such as occupying a large space above the ground when in transit, insufficient concealment, and low integration, resulting in poor applicability to some specific application scenarios. Utility Model Content

[0004] Therefore, it is necessary to provide a folding hydraulic roadblock machine to address the technical problems of existing roadblock machines occupying a large space above ground and lacking concealment when in operation.

[0005] A folding hydraulic roadblock machine includes a main frame, a sub-frame, an adjustable base plate, and a flip plate. The adjustable base plate is set on a preset installation ground, and the main frame and sub-frame are respectively set at both ends of the adjustable base plate. The flip plate is set on the top side of the adjustable base plate. The main frame and sub-frame are connected by a drive and drive the flip plate to control the undulation of the flip plate. Based on this, the flip plate can rise and fall with the coordinated drive of the main frame and sub-frame, thereby forming a folding roadblock mechanism.

[0006] The main frame is equipped with a controller, a hydraulic power unit, and a first hydraulic cylinder, all of which are housed inside the main frame. The output of the controller is electrically connected to the input of the hydraulic power unit and the input of the first hydraulic cylinder, enabling the controller to drive and control the hydraulic power unit and the first hydraulic cylinder. The output of the hydraulic power unit is connected to the input of the first hydraulic cylinder, and the output of the first hydraulic cylinder drives and connects to the flap. Thus, the hydraulic power unit and the first hydraulic cylinder form a hydraulic drive mechanism that outputs power to the flap, lifting the flap to form a roadblock.

[0007] In one embodiment, the sub-frame is provided with a second hydraulic cylinder, which is housed and installed inside the sub-frame. The input end of the second hydraulic cylinder is connected to the output end of the controller and the output end of the hydraulic power unit, respectively. The output end of the second hydraulic cylinder drives the connecting flap.

[0008] The flip plate includes a first drive plate and a second drive plate; the two sides of the first drive plate are respectively set as a rotating side and a flipping side, wherein the two ends of the rotating side of the first drive plate are respectively rotatably connected to the main frame and the sub-frame; the two sides of the second drive plate are respectively set as a driven side and a sliding side, the driven side is movably connected to the flipping side, and the two ends of the sliding side are respectively slidably connected to the main frame and the sub-frame, and the first hydraulic cylinder and the second hydraulic cylinder drive the sliding side.

[0009] The flip plate also includes a hinge, which is located between the first drive plate and the second drive plate. The flip side of the first drive plate is hinged to the driven side of the second drive plate through the hinge, thereby realizing the linkage between the first drive plate and the second drive plate.

[0010] The flap also includes a first rotating shaft and a second rotating shaft. The first rotating shaft is located on the rotating side of the first drive plate, and its two ends are connected to the main frame and the sub-frame, respectively. The second rotating shaft is located on the sliding side of the second drive plate, and its two ends are connected to the first hydraulic cylinder and the second hydraulic cylinder, respectively.

[0011] In one embodiment, the main frame and the sub-frame are respectively provided with grooves at the ends of the second rotating shaft, and each groove is arranged parallel to each other along a preset ground plane.

[0012] In one embodiment, the two ends of the second rotating shaft are respectively slidably engaged with the corresponding end of the sliding groove, thereby achieving stable sliding of the sliding side of the second drive plate.

[0013] In one embodiment, the flap further includes a plurality of first support tubes disposed on the bottom surface of the first drive plate, and each first support tube extends along the length direction of the first drive plate.

[0014] In one embodiment, the flap further includes a plurality of second support tubes disposed on the bottom surface of the second drive plate, and each second support tube extends along the length direction of the second drive plate.

[0015] In one embodiment, the first drive plate and the second drive plate are both made of 10mm steel plate and 3mm lentil-patterned steel plate stacked together.

[0016] In one embodiment, both the first support tube and the second support tube are made of steel pipe of a preset size.

[0017] In one embodiment, the overall dimensions of the aforementioned folding hydraulic roadblock machine are set to 3520mm (length) * 1470mm (depth) * 880mm (width).

[0018] In one embodiment, the aforementioned flap lifting dimensions are set to 3000mm (length) * 338mm (height).

[0019] In one embodiment, the main frame is further provided with a traffic indicator light, an open status detection unit, and a vehicle passage detection unit. The traffic indicator light is located on the top of the main frame, and the open status detection unit and the vehicle passage detection unit are located inside the main frame. They detect the open status of the roadblock and the vehicle passage through a preset sensor array, respectively.

[0020] The aforementioned folding hydraulic road barrier machine adjusts the undulation of the base plate through the main / sub-frame drive, thereby raising and lowering the flap, achieving the "folding" and unfolding of the road barrier. In the blocking state, the flap stands upright to form an obstacle; in the releasing state, the flap descends with the base plate, minimizing its occupation of above-ground space and allowing it to be completely retracted to a position flush or nearly flush with the ground. This significantly reduces visual interference and physical obstruction when the equipment is not in operation, improving road aesthetics and traffic flow; it also reduces the requirement for underground foundation depth (compared to integral rising bollards). Furthermore, the hydraulic drive provides powerful and reliable performance, ensuring the flap can rise quickly, smoothly, and forcefully, possessing high impact resistance. The hydraulic transmission itself has overload protection characteristics; when the system pressure reaches a set value, the overflow valve activates to protect system components. The flap is directly driven by the first hydraulic cylinder, achieving effective force transmission and synchronous movement (the main and sub-frames work together), ensuring the flap's overall smooth raising and lowering, avoiding jamming or twisting.

[0028] Please see Figures 1 to 4This utility model discloses a folding hydraulic roadblock machine 1, which includes a main frame 10, a secondary frame 20, an adjustable base plate 30, and a flip plate 40. The adjustable base plate 30 is set on a preset installation ground, the main frame 10 and the secondary frame 20 are respectively set at both ends of the adjustable base plate 30, and the flip plate 40 is set on the top side of the adjustable base plate 30. The main frame 10 and the secondary frame 20 are connected by a transmission and drive the flip plate 40 to control the undulation of the flip plate 40. Based on this, the flip plate 40 can rise and fall with the coordinated drive of the main frame 10 and the secondary frame 20, thereby forming a folding roadblock mechanism. Specifically, the main frame 10 is equipped with a controller 11, a hydraulic power unit 12, and a first hydraulic cylinder 13. The controller 11, the hydraulic power unit 12, and the first hydraulic cylinder 13 are all housed and installed inside the main frame 10. The output end of the controller 11 is electrically connected to the input end of the hydraulic power unit 12 and the input end of the first hydraulic cylinder 13, thereby enabling the controller 11 to drive and control the hydraulic power unit 12 and the first hydraulic cylinder 13. The output end of the hydraulic power unit 12 is connected to the input end of the first hydraulic cylinder 13, and the output end of the first hydraulic cylinder 13 drives and connects to the flap 40. Thus, the hydraulic power unit 12 and the first hydraulic cylinder 13 form a hydraulic drive mechanism to output power to the flap 40, thereby lifting the flap 40 to form a roadblock. Based on the above configuration, the folding hydraulic roadblock machine 1 of this utility model drives the adjustment of the base plate 30 through the main frame 10 / sub-frame 20, thereby driving the flap 40 to rise and fall, realizing the "folding" and unfolding of the roadblock. In the blocking state, the flap 40 stands upright to form an obstacle; in the releasing state, the flap 40 descends with the base plate, minimizing the occupation of the space above ground and being completely retracted to a position flush or nearly flush with the ground. This significantly reduces visual interference and physical obstruction of the equipment when not in operation, improving road aesthetics and traffic flow; and reduces the requirement for underground foundation depth (compared to integral rising bollards). Furthermore, the hydraulic drive provides strong power and reliability, ensuring that the flap 40 can rise quickly, smoothly, and powerfully, possessing high impact resistance. The hydraulic transmission itself has overload protection characteristics; when the system pressure reaches the set value, the overflow valve operates to protect system components. The flap 40 is directly driven by the first hydraulic cylinder 13, which realizes the effective transmission of force and the synchronization of movement (the main and auxiliary frames 20 work together), ensuring that the flap 40 rises and falls smoothly as a whole, and avoiding jamming or twisting.

[0029] Furthermore, the sub-frame 20 is equipped with a second hydraulic cylinder 21, which is housed inside the sub-frame 20. The input end of the second hydraulic cylinder 21 is connected to the output end of the controller 11 and the output end of the hydraulic power unit 12, respectively. The output end of the second hydraulic cylinder 21 drives the flap 40. Based on this, the main frame 10 and the sub-frame 20 are located at both ends of the adjusting base plate 30, respectively, and are connected by transmission to jointly drive the flap 40 to rise and fall. This symmetrical or distributed support structure can significantly improve the structural rigidity and stability of the entire roadblock mechanism in the raised state, especially resisting the lateral force or torsion generated during vehicle impact, preventing the flap 40 from overturning or deforming, and improving the overall impact resistance and service life.

[0030] Furthermore, the flip plate 40 includes a first drive plate 41 and a second drive plate 42; the two sides of the first drive plate 41 are respectively configured as a rotating side 411 and a flipping side 412, wherein the two ends of the rotating side 411 of the first drive plate 41 are respectively rotatably connected to the main frame 10 and the sub-frame 20, so that the first drive plate 41 can flip up and fall back relative to the bottom surface with the rotating side 411 as the axis; the two sides of the second drive plate 42 are respectively configured as a driven side 421 and a sliding side 422, the driven side 421 is movably connected to the flipping side 412, and the two ends of the sliding side 422 are respectively slidably connected to the main frame 10 and the sub-frame 20. Based on this, when the roadblock is in the passage state, the first hydraulic cylinder 13 and the second hydraulic cylinder 21 respectively drive the two ends of the sliding side 422 connected to the second drive plate 42. Thus, the first hydraulic cylinder 13 and the second hydraulic cylinder 21 can drive the sliding side 422 towards the first drive plate 41 through cooperation, causing the second drive plate 42 to flip up. The driven side 421 of the second drive plate 42 is linked to the flipped side 412 of the first drive plate 41, which in turn causes the rotating side 411 of the first drive plate 41 to rotate relative to the main frame 10 and the sub-frame 20. At this time, the first drive plate 41 and the second drive plate 42 form a raised structure to form the blocking state of the roadblock.

[0031] Furthermore, the flip plate 40 also includes a hinge 43, which is disposed between the first drive plate 41 and the second drive plate 42. The flip side 412 of the first drive plate 41 is hinged to the driven side 421 of the second drive plate 42 through the hinge 43, thereby realizing the linkage between the first drive plate 41 and the second drive plate 42.

[0032] Furthermore, the flap 40 also includes a first rotating shaft 44 and a second rotating shaft 45. The first rotating shaft 44 is disposed on the rotating side 411 of the first drive plate 41, and its two ends are respectively connected to the main frame 10 and the sub-frame 20. The second rotating shaft 45 is disposed on the sliding side 422 of the second drive plate 42, and its two ends are respectively connected to the first hydraulic cylinder 13 and the second hydraulic cylinder 21.

[0033] Furthermore, the main frame 10 and the sub-frame 20 are respectively provided with sliding grooves a at the ends of the second rotating shaft 45, and each sliding groove a is arranged parallel to each other along a preset ground plane. Based on this, the two ends of the second rotating shaft 45 are respectively slidably engaged with the sliding grooves a at the corresponding ends, thereby realizing the stable sliding of the sliding side 422 of the second drive plate 42.

[0034] Furthermore, the flap 40 also includes a plurality of first support tubes 46, which are disposed on the bottom side surface of the first drive plate 41. Each first support tube 46 extends along the length of the first drive plate 41 to strengthen the mechanical strength of the first drive plate 41 and improve its impact and torsional resistance.

[0035] Furthermore, the flap 40 also includes a plurality of second support tubes 47, which are disposed on the bottom surface of the second drive plate 42. Each second support tube 47 extends along the length of the second drive plate 42 to strengthen the mechanical strength of the second drive plate 42 and improve its impact resistance and torsional resistance.

[0036] Furthermore, in one embodiment, the first drive plate 41 and the second drive plate 42 are both made of 10mm steel plate and 3mm lentil-patterned steel plate stacked together; in another embodiment, the first support tube 46 and the second support tube 47 are both made of steel tubes of a preset size.

[0037] Furthermore, in one embodiment, the overall dimensions of the folding hydraulic roadblock machine 1 are set to 3520mm (length) * 1470mm (depth) * 880mm (width).

[0038] Furthermore, in one embodiment, the lifting dimensions of the flap 40 are set to 3000mm (length) * 338mm (height).

[0039] Furthermore, the main frame 10 is also equipped with a traffic indicator light 50, an open status detection unit (not shown), and a vehicle passage detection unit (not shown). The traffic indicator light 50 is located on the top of the main frame 10, and the open status detection unit and the vehicle passage detection unit are located inside the main frame 10. They detect the open status of the roadblock and the vehicle passage through a preset sensor array, respectively.

[0040] In summary, the folding hydraulic roadblock machine disclosed in this utility model achieves the "folding" and unfolding of the roadblock body by adjusting the undulation of the base plate through the main frame / sub-frame drive, thereby driving the flap to rise and fall. In the blocking state, the flap stands upright to form an obstacle; in the releasing state, the flap descends with the base plate, minimizing the occupation of the space above ground and being able to be completely stored at or near-level with the ground. This significantly reduces visual interference and physical obstruction of the equipment when not in operation, improving road aesthetics and traffic flow; it also reduces the requirements for underground foundation depth (compared to integral rising bollards). Furthermore, the hydraulic drive provides strong power and reliability, ensuring that the flap can be raised quickly, smoothly, and forcefully, possessing high impact resistance. The hydraulic transmission itself has overload protection characteristics; when the system pressure reaches the set value, the overflow valve operates to protect system components. The flap is directly driven by the first hydraulic cylinder, achieving effective force transmission and synchronous movement (the main and sub-frames work together), ensuring the overall smooth lifting and lowering of the flap and avoiding jamming or twisting.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
