Height limiting frame for road overload control

Abstract

The invention discloses a height limiting frame for road overload control, which comprises stand columns and a height limiting rod, an outer sliding groove is formed in the outer side of the interior of each stand column, an inner sliding groove is formed in the inner side of each outer sliding groove, an outer sliding rod is arranged in each outer sliding groove, an inner sliding rod is arranged in each inner sliding groove, and a pressure sensor is arranged at the upper end of each outer sliding groove. Connecting ends are arranged on the inner sides of the stand columns, through holes are formed in the connecting ends, sleeve rods are arranged in the through holes, upper springs are arranged on the surfaces of the upper ends of the sleeve rods, lower springs are arranged on the lower sides of the upper springs, limiting blocks are arranged at the lower ends of the lower springs, and contact guide blocks are arranged on the surfaces of the height limiting rods. A warning board is arranged on the inner sides of the contact guide blocks, and a connecting block is arranged on the rear sides of the contact guide blocks. According to the height limiting frame for road overload control, an early warning device and a warning device are additionally arranged, and the probability of traffic accidents caused by the fact that a driver does not estimate the height of a self-driving vehicle accurately is effectively reduced.

Description

technical field [0001] The invention relates to the related technical field of road treatment devices, in particular to a restricted elevated roadway for road treatment overload. Background technique [0002] Elevation-limiting viaducts are generally used in bridges, tunnels, roads and other places where the height of vehicles is limited. Its function is to prevent the passage of super-high vehicles, thereby avoiding damage to bridges and tunnels. The traditional elevation-limiting overpass has a single function and lacks early warning And the warning function, the driver sometimes underestimates the height of his own vehicle, which will cause the top of the vehicle to scratch the height limit device, resulting in damage to the vehicle or goods, and in severe cases, casualties; For this reason, it is often impossible to pay attention to the height limit rack in time, resulting in accidental injury, and it cannot be intercepted in time. When the driver does not notice the hei...
