Road and bridge vehicle height limit detection device

Abstract

The invention provides a vehicle height limit detection device for roads and bridges, which comprises fixing frames, a 4G module and a cloud end. There are two fixing frames. A touch sensor is electrically connected with a microprocessor. The invention can exert a fixing function on the one hand by the arrangement of the spring A, and prevents the windblown limit plate from swaying in the windy weather, causing the limit plate swaying over contact with the touch sensor to cause an error signal. On the other hand, the resetting effect can be exerted. When the vehicle height exceeds the limit height, the vehicle pushes the height limit plate to rotate, and the spring A can push the height limit plate to reset after the vehicle passes. Through the matching arrangement of the hook and the latch, on the one hand, because the hook is rotatably connected with the cylindrical crossbar, the vehicle exceeding the height limit can push the height limit plate to rotate along the cylindrical crossbar to prevent the device from being damaged; on the other hand, the latch on the hook is convenient to disassemble and install the height limit plate, thus reducing the complexity of maintenance and replacement.

Description

technical field [0001] The invention belongs to the technical field of road supporting equipment, and more specifically relates to a height limit detection device for road bridge vehicles. Background technique [0002] The height limit pole can better ensure traffic safety, and it plays a good role in preventing vehicles from being super high and protecting road facilities. It is installed on many roads, but it often occurs that vehicles will damage the height limit pole, causing vehicles And the height limit pole is damaged, which also affects the traffic. The reason is that the traditional height limit pole has a single function and cannot be detected and warned in advance, resulting in the driver not observing carefully or erroneously estimating the height of the vehicle, which often leads to accidents. [0003] Based on the inventor’s discovery above, the main disadvantages of the existing vehicle height limiting devices are that the structure is relatively fixed, easil...
