[0002] Height limiters, as an effective device for limiting vehicle height, are currently widely used on roads and along bridges, tunnels, culverts, and other areas where height restrictions are imposed. Generally speaking, a height limiter consists of two supporting columns and a crossbeam placed horizontally above the road, forming a portal structure. The column height is designed according to bridge height restrictions. Once installed, the crossbeam is fixed, and the height limiter forms a single, integrated structure.
[0003] When the height of the height limit frame is fixed, it is necessary to manually remove the height limit frame for sections of road where height-restricted vehicles need to pass in different time periods, which greatly increases the workload of traffic control personnel. Especially when special vehicles pass through, it is very troublesome, time-consuming and labor-intensive to remove the height limit frame.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] like Figures 1-6 As shown, the technical solution adopted by the utility model is as follows: a height limiting device for roads and bridges, comprising a first column 1 and a second column 2 respectively arranged on both sides of the road, a first beam 3 respectively installed on the first column 1 and a second beam 4 installed on the second column 2, the first beam 3 and the second beam 4 are both installed on the corresponding first column 1 and the second column 2 through an adjusting component, and the adjusting component can adjust the height or angle of the first beam 3 and the second beam 4 simultaneously or separately.
[0024] In this embodiment, the first and second columns 1 and 2 are constructed of the same material. They serve as the support structure for the height-limiting device, providing stable support. Each of the first and second columns 1 and 2 has integrally formed connecting flanges. The bottoms of the first and second columns 1 and 2 are secured to the ground using connecting bolts. The first and second columns 1 and 2 work together to form the height-limiting frame structure.
[0025] In this embodiment, the adjustment assembly includes a mounting frame 5, a longitudinal adjustment member 6 disposed within the mounting frame 5, and a rotary adjustment member 7 installed between the longitudinal adjustment member 6 and the first crossbeam 3 or the second crossbeam 4. The first crossbeam 3 and its corresponding longitudinal adjustment member 6 are installed with a rotary adjustment member 7, and the second crossbeam 4 and its corresponding longitudinal adjustment member 6 are installed with a rotary adjustment member 7. It should be noted that the longitudinal adjustment member 6 is used to adjust the height of the first crossbeam 3 and the second crossbeam 4, thereby adjusting the height limit. The rotary adjustment member 7 is used to adjust the horizontal angle of the first crossbeam 3 and the second crossbeam 4, removing the height limit and allowing special vehicles to pass.
[0026] In this embodiment, a connecting flange is integrally formed at the bottom of the mounting frame 5. When the mounting frame 5 is installed on the first column 1 and the second column 2, the connecting flange of the mounting frame 5 cooperates with the connecting flanges of the first column 1 and the second column 2 and is fastened by connecting bolts.
[0027] In this embodiment, a longitudinal slot is defined within the mounting frame 5. A connecting slot is defined on one side of the mounting frame 5, communicating with the longitudinal slot. A limit slot is defined longitudinally on the inner wall of the mounting frame 5. The longitudinal adjustment member 6 includes an adjustment motor 61, an adjustment screw 62 coaxially fixed to the adjustment motor 61, and a slider 63 mounted within the longitudinal slot. The slider 63 has a threaded hole defined longitudinally that mates with the adjustment screw 62.
[0028] It should be noted that a limit block is mounted on the side wall of the slider 63, and the limit block slides within the limit slot. The adjustment motor 61 rotates the adjustment screw 62, which drives the slider 63 to move longitudinally within the longitudinal slot, thereby driving the longitudinal movement of the first crossbeam 3 or the second crossbeam 4.
[0029] In this embodiment, the rotary adjustment member 7 includes a first rotary seat 71 and a second rotary seat 72 rotatably adapted to the first rotary seat 71. The first rotary seat 71 is fixed to the slider 63 via connecting bolts. One of the second rotary seats 72 is integrally formed with the first crossbeam 3, and one of the second rotary seats 72 is integrally formed with the second crossbeam 4. The first crossbeam 3 or the second crossbeam 4 can be horizontally rotated by the rotary adjustment member 7.
[0030] In this embodiment, a first locking member 8 is provided between the second rotating seat 72 and the first beam 3 or the second beam 4. Specifically, a locking hole is provided on the second rotating seat 72, and a threaded hole corresponding to the locking hole is provided on the first beam 3 or the second beam 4. The first locking member 8 is a first locking bolt, which is screwed into the corresponding threaded hole through the locking hole, thereby limiting the first beam 3 or the second beam 4.
[0031] In this embodiment, a second locking member 9 is provided between the first crossbeam 3 and the second crossbeam 4. Specifically, a locking flange is integrally formed at the proximal ends of the first crossbeam 3 and the second crossbeam 4, and the two locking flanges are fixedly connected by the second locking member 9. The second locking member 9 is a second locking bolt, and the locking flange has a threaded hole that is compatible with the second locking bolt.
[0032] In this embodiment, a mounting slot is defined at the top of the mounting frame 5, within which a displacement sensor 10 is mounted. A controller and battery are also installed within the mounting frame 5, and a display screen 11 is mounted on the first crossbeam 3 and / or the second crossbeam 4. The displacement sensor 10, controller, battery, and display screen 11 are electrically connected. When the first and second crossbeams 3 and 4 are adjusted longitudinally using the adjustment assembly, the displacement sensor 10 displays the limit height in real time on the display screen 11.
[0033] In this embodiment, the first column 1 and the second column 2 are both welded with reinforcement columns to improve the overall stability of the height limiting device.
[0034] When the device is in use, in its initial state, the first crossbeam 3 and the second crossbeam 4 are fixedly connected by the second locking member 9, forming a single crossbeam. The longitudinal adjustment members 6 mounted on the first and second uprights 1 and 2 operate synchronously to change the height of the first and second crossbeams 3 and 4, thereby adjusting the height limit. When a special vehicle needs to pass, the first and second locking members 8 and 9 are released, causing the first and second crossbeams 3 and 4 to rotate horizontally, releasing the height limit and allowing the special vehicle to pass.
[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
