Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-5This utility model provides a technical solution: an adjustable highway traffic height restriction device, including a support frame 100; a limiting structure is connected to the support frame 100, the limiting structure is used to limit the height of vehicles passing through, a rotating shaft 204 and a connecting rod 300 are connected to the limiting structure, an adjustment structure is connected to the rotating shaft 204, the adjustment structure is used to adjust the height of the limiting structure to adapt to different road conditions, an alarm structure is connected to the connecting rod 300, the alarm structure is used to issue an alarm when a vehicle exceeds the height limit, and a blocking structure is connected inside the support frame 100, the blocking structure is used to block the vehicle in front of it when it exceeds the height limit.

[0025] Furthermore, the limiting structure includes a height limiting rod 200, which is slidably mounted on a support frame 100. A connecting shaft 201 is rotatably mounted inside the support frame 100. A take-up and release roller 202 is fixedly sleeved on the connecting shaft 201. One end of a connecting rope 203 is mounted on the take-up and release roller 202. The other end of the connecting rope 203 passes through the support frame 100 and is mounted on the height limiting rod 200. The connecting rope 203 is wound around the take-up and release roller 202. The height limiting rod 200 can be used to limit the height of vehicles. When the connecting shaft 201 rotates, it can drive the take-up and release roller 202 to rotate. The take-up and release roller 202 can take up and release the connecting rope 203. When the connecting rope 203 is taken up, it can pull the height limiting rod 200 up. When the take-up and release roller 202 releases the taken-up connecting rope 203, the height limiting rod 200 will descend under its own weight.

[0026] Furthermore, the adjustment structure includes two transmission wheels 205, which are respectively fixedly sleeved on the connecting shaft 201 and the rotating shaft 204. The rotating shaft 204 is rotatably installed inside the support frame 100. The same transmission belt 206 is driven and installed on the two transmission wheels 205. A worm gear 207 is fixedly sleeved on the rotating shaft 204. A worm 208 is rotatably installed inside the support frame 100, and the worm 208 meshes with the worm gear 207. A motor 209 is installed on one side of the support frame 100. The output end of the motor 209 is installed on the worm 208. Turning on the motor 209 can control the rotation of the worm 208. The rotating worm 208 can drive the rotating shaft 204 to rotate through meshing with the worm gear 207, thereby causing the rotating shaft 204 to drive one of the transmission wheels 205 to rotate. This transmission wheel 205 can drive the other transmission wheel 205 to rotate through the transmission engagement with the transmission belt 206, thereby causing it to drive the connecting shaft 201 to rotate.

[0027] Furthermore, guide grooves 210 are provided on both inner walls of the support frame 100, and guide blocks 211 are slidably installed in both guide grooves 210. The two guide blocks 211 are respectively installed on both sides of the height limit bar 200. During the movement of the height limit bar 200, the guide blocks 211 will slide in the corresponding guide grooves 210, thereby restricting the vertical movement of the height limit bar 200 and preventing it from deviating.

[0028] Example 2: As Figure 1-5 To promptly alert the driver to stop and check when a vehicle exceeds the height limit, an alarm structure is installed. This structure includes two laser sensors 301, each mounted between two connecting rods 300. Both connecting rods 300 are mounted on one side of the height limit bar 200, with the laser sensors 301 corresponding to each other. An alarm 302 is mounted above the support frame 100, and the alarm 302 is connected to the same control module as the two laser sensors 301. Two L-shaped support frames 303 are mounted on one side of the support frame 100, each with a vertical groove 304 inside. The two vertical grooves 304 allow for the sliding of... The vehicle is equipped with two vertical sliders 305, which are respectively installed on one side of the two connecting rods 300. Several speed bumps 306 are installed on the two L-shaped support frames 303. By setting multiple speed bumps 306 on the two L-shaped support frames 303, the driver can be forced to slow down. When the height limit bar 200 is raised and lowered, it will drive the corresponding connecting rod 300 and laser sensor 301 to rise and fall. When the vehicle height is higher than the height of the height limit bar 200, it will block the two laser sensors 301 and block the signal. The laser sensor 301 will transmit a signal to the control module to control the alarm 302 to sound an alarm and promptly remind the driver that the vehicle is too high. The remaining features are the same as in Embodiment 1.

[0029] Example 3: As Figure 1-3 In order to restrict the passage of oversized vehicles and reduce the occurrence of accidents, a blocking structure is arranged. The blocking structure includes a limiting baffle 400, which is slidably installed inside the support frame 100. A connecting plate 401 is installed on one side of the limiting baffle 400. An electric push rod 402 is installed inside the support frame 100. The telescopic end of the electric push rod 402 is installed below the connecting plate 401. The electric push rod 402 is connected to the control module. While the signals of the two laser sensors 301 are blocked, the control module can send a signal to the electric push rod 402 to control its operation. The telescopic end of the electric push rod 402 extends and pushes the corresponding connecting plate 401 and the limiting baffle 400 to rise, blocking the vehicle in front. The remaining features are the same as in Embodiment 2.

[0030] The working principle is as follows: By turning on the motor 209, the worm gear 208 can be controlled to rotate. The rotating worm gear 208 can drive the rotating shaft 204 to rotate through meshing with the worm wheel 207. In turn, the rotating shaft 204 drives one of the transmission wheels 205 to rotate. This transmission wheel 205 can drive the other transmission wheel 205 to rotate through the transmission belt 206. In turn, it drives the connecting shaft 201 and the take-up and unwind roller 202 to rotate. The rotating take-up and unwind roller 202 can take in and unwind the connecting rope 203. When the connecting rope 203 is wound up, it can pull the height limit bar 200 to rise. The take-up and unwind roller 202 will take in the connected rope. When the connecting rope 203 is released, the height restriction bar 200 will descend under its own weight, thereby adjusting the height of the height restriction bar 200. As the height restriction bar 200 rises and falls, it will drive the corresponding connecting rod 300 to rise and fall, so that the connecting rod 300 can drive the vertical slider 305 to slide within the vertical slide groove 304, thereby restricting the vertical movement of the connecting rod 300. As the connecting rod 300 moves, it will drive the laser sensor 301 to move, so that the laser sensor 301 can rise and fall with the movement of the height restriction bar 200. The height restriction bar 200 can be adjusted to a suitable height to restrict vehicle passage according to the road environment.

[0031] When a vehicle is traveling, it can pass between the two L-shaped support frames 303. By setting multiple speed bumps 306 on the two L-shaped support frames 303, the driver can be forced to slow down. When the vehicle height is higher than the height limit bar 200, it will be blocked between the two laser sensors 301. The two laser sensors 301 are the transmitter and receiver of the sensor, respectively. When the vehicle blocks the signal of the two laser sensors 301, the laser sensors 301 will transmit a signal to the control module, which is a PLC controller, to control the alarm 302 to sound an alarm and promptly remind the driver that the vehicle is too high. At the same time, the control module sends a signal to the electric push rod 402 to control the operation of the electric push rod 402. The telescopic end of the electric push rod 402 extends and pushes the corresponding connecting plate 401 and the limiting baffle 400 to rise, blocking the vehicle in front and restricting the vehicle's passage.
