[0002] Over-limit means that the length, width, height and load mass of a freight vehicle exceed the prescribed limits. When a vehicle exceeds this standard, it is called over-limit.

[0003] To prevent traffic accidents caused by vehicles exceeding the limit, overload detection and warning devices are installed on roads. For example, in the prior art patent application with publication number CN 216809686 U, a gantry structure is installed on the top of the base, and an anti-collision warning structure is installed on the top of the gantry structure. The anti-collision warning structure includes two sound and light alarms fixedly installed on the top of the gantry structure. The top of the gantry structure is fixedly connected to a first fixed box, the inner bottom wall of the first fixed box is fixedly connected to a battery, and the inner bottom wall of the first fixed box is fixedly connected to a solar controller. The top of the gantry structure is fixedly connected to a second fixed box, and the inner bottom wall of the second fixed box is fixedly connected to a control device.

[0030] The sensor 6 is fixedly mounted on the top of the top plate 5 . Warning lights 62 are fixedly mounted on both ends of the top of the top plate 5 . A display screen 61 is fixedly mounted on the front of the top plate 5 .

[0031] A disc 12 is fixedly mounted on the top of the fixing rod 1 , and a plurality of positioning holes 13 are formed inside the disc 12 .

[0032] A side plate 14 is fixedly mounted on the bottom of the side of the support rod 11 , and a positioning screw 15 is connected to the inner thread of the side plate 14 .

[0033] A control box 2 is fixedly mounted on the side of the fixing rod 1 , and the control box 2 is electrically connected to the driving motor 56 .

[0034] The sensor 6 is electrically connected to the warning light 62 and the display screen 61 respectively.

[0035] The sensor 6 is an infrared sensor. When in use, the infrared sensor measures the height of the vehicle. When the height exceeds the limit, the warning light 62 sounds an alarm. At the same time, the content on the display 61 can give the driver a second warning to increase the warning intensity.

[0036] The worm gear 58 is driven by the worm 57 to rotate, and after the mounting frame 51 and the top plate 5 are moved to the appropriate position, they can be self-locked;

[0037] A controller is provided on the inner side of the control box 2 . When in use, the controller can be used to control the driving motor 56 to rotate forward and reverse, thereby adjusting the height of the top plate 5 and the mounting frame 51 .

[0038] The working principle of the highway vehicle overload detection and warning device provided by the utility model is as follows:

[0039] During use, when it is necessary to maintain other electronic equipment such as the sensor 6, display screen 61 and warning light 62, the user can first rotate the positioning screw 15 to move the bottom of the positioning screw 15 out from the inner side of the positioning hole 13, and then rotate the support rod 11, so that the support rod 11 drives the top of the cross bar 3 to move to the top of the roadside, and then controls the drive motor 56 to rotate through the control box 2, so that the drive motor 56 drives the worm 57 and the worm gear 58 to engage, and then the worm gear 58 drives the two winding wheels 54 to rotate through the rotating shaft 53, thereby releasing the pull rope 55 and moving the top plate 5 and the mounting frame 51 to the ground. This makes it convenient for the staff to maintain other electronic equipment such as the sensor 6, display screen 61 and warning light 62.

[0040] Compared with related technologies, the highway vehicle overload detection and warning device provided by the present invention has the following beneficial effects:

[0041] By driving the motor 56 to engage the worm 57 and the worm wheel 58, the rotating shaft 53 drives the winding wheel 54 to release the pull rope 55 wrapped around the outside, so that the top plate 5 and the mounting frame 51 can drive the sensor 6, display screen 61, warning light 62 and other electronic equipment to move to the ground. In this way, there is no need to use other tools to climb up to maintain the electronic equipment, which not only facilitates the operation of the staff, but also reduces the risk.

[0042] Second embodiment

[0045] The spring telescopic rod 71 is disposed at the bottom of the display screen 61 .

[0046] The working principle of the highway vehicle overload detection and warning device provided by the utility model is as follows:

[0047] When in use, the two connecting rods 7 are installed at the bottom of the mounting frame 51, and then the two spring telescopic rods 71 ​​are installed on the front of the two connecting rods 7, and then the anti-collision rod 72 is installed on the front of the two spring telescopic rods 71, so that the anti-collision rod 72 is in the front of the bottom of the display screen 61. When it is hit, the anti-collision rod 72 can first contact the impact object, thereby protecting the display screen 61.
