Description

Technical Field

[0001] The utility model relates to the technical field of expressway ramp control, in particular to an expressway ramp control gantry. Background Art

[0002] A ramp, also known as an approach road, is an engineering term that generally refers to a short section of land bridge / incline / approach road connecting vehicles to and from a main road (expressway, elevated road, bridge, tunnel, etc.) and an adjacent auxiliary road, or other main roads, as well as a collector-distributor road. A gantry is required for control at the entrance of an expressway ramp.

[0003] In the current road system, expressway ramp control gantries, as important traffic management facilities, play a key role. These gantries are usually set at a certain height to restrict the passage of overheight vehicles, thereby ensuring road safety and smooth flow. However, although this fixed-height design can limit vehicle height to a certain extent, it still has some limitations. For those vehicles whose height does not reach the gantry limit but is still within the prohibited area, the existing expressway ramp control gantries are often unable to effectively block them, which means that these vehicles may mistakenly enter the expressway ramp, thereby posing certain safety hazards to the driving section. This needs to be optimized and improved. Utility Model Content

[0037] In this embodiment: by arranging two sets of upper and lower gate crank arm rods 4 and connecting components 6 on the inner side of the gantry 1, and cooperating with the detection and analysis of the camera 10, vehicles that are prohibited from passing through the expressway inside the gantry 1 are effectively blocked, reducing the limitations of the existing method of controlling vehicle entry only by height restrictions, and reducing safety hazards in road driving.

[0038] Furthermore, the inner side of the height limiting beam 7 can be plugged in and fixed, which is convenient for disassembly and replacement. The indicating installation component 11 at the front end of the height limiting beam 7 can be elastically positioned by squeezing first and then installed and fixed, thereby improving the convenience of installation.

[0039] Specifically, such as Figure 2 As shown, the gate crank arm 4 includes a rotary motor 401, which is fixedly mounted on the two supporting legs of the gantry 1. The rotary motor 401 is used to directly drive the inner support rod 402 to perform a swinging motion. The inner side of the inner support rod 402 is rotatably connected to a half gear 403, and the outer side of the inner support rod 402 is rotatably connected to an external rotating connector 404, and the inner side of the external rotating connector 404 is rotatably connected to a folding rod 405.

[0040] In this embodiment: the rotating motor 401 drives the inner support rod 402 to rotate, and then the inner support rod 402 and the folding rod 405 are connected by two half gears 403, so that the maximum rotation angle can only reach one hundred and eighty degrees, and the external rotating connecting piece 404 can facilitate the control of the rotation of the inner support rod 402 and the folding rod 405.

[0041] Specifically, such as Figure 2As shown, the connecting assembly 6 includes a connecting rod 601, and the connecting rod 601 is rotatably connected to the inner bottom end of the external rotating connecting member 404, and the inner side of the connecting rod 601 is rotatably connected to a rotating connecting block 602;

[0042] In this embodiment, the connecting rod 601 is connected to the inner bottom end of the external rotating connector 404, and the other end is connected to the bottom end of the rotating motor 401 through the rotating connecting block 602, so as to provide limited rotation support.

[0043] Specifically, such as Figure 3 As shown, the height limiting beam 7 includes a grooved fixing plate 701, and the grooved fixing plate 701 is fixedly installed on the top of the door frame 1, and the inner side of the top wall of the grooved fixing plate 701 is plugged and fixed with a plug-in support column 702, and the outer side of the top end of the plug-in support column 702 is clamped and fixed with a top mounting bracket 703;

[0045] Specifically, such as Figure 4 As shown, the indicator installation assembly 11 includes a passage indicator 1101, and the passage indicator 1101 is fixedly arranged on the left and right sides of the front end of the grooved fixing plate 701. Buffer pads 1102 are bonded to the upper and lower ends of the rear end of the passage indicator 1101, and a sliding clamping block 1103 is slidably connected to the middle part of the rear end of the passage indicator 1101. The inner side of the sliding clamping block 1103 is elastically supported by an elastic support rod 1104.

[0046] In this embodiment: the passage sign 1101 can provide passage indication. During installation, the sliding clamping blocks 1103 at the upper and lower ends are used to squeeze the elastic support rod 1104 toward the middle, and then clamped into the installation groove reserved inside the grooved fixing plate 701. At this time, the buffer pad block 1102 is located between the passage sign 1101 and the grooved fixing plate 701 for support and protection, thereby improving the stability of the installation.

[0047] The specific solution is as follows: first, a road sign 9 is installed at the front end of the top mounting frame 703 for information indication, a camera 10 installed in the middle can monitor the vehicle information on the driving section, and the gate information screen 3 at the front end displays the road traffic information. When encountering a vehicle that needs to be intercepted, the rotating motor 401 drives the inner support rod 402 to rotate, and then the inner support rod 402 and the folding rod 405 are connected by two half gears 403, so that the maximum rotation angle can only reach one hundred and eighty degrees.
