Load limiter on roads

Abstract

The invention discloses a load limiter on the roads, comprising a top plate, a load bearing apparatus and a spray apparatus, wherein the top plate is positioned on the upper part of the load bearing apparatus and is in fit connection with the load bearing apparatus against press; the spray apparatus is connected with the load bearing apparatus; the load bearing apparatus consists of a plurality of cylinder bodies arranged vertically; pistons are arranged in and in sliding fit with the cylinder bodies; compression springs are installed between the bottom surfaces of the pistons and the bottoms of the cylinders, the tops of the pistons are in fit connection with the top plate against press. The invention is characterized by reasonable design, simple structure, low cost and good endurance for use, which is used for cautioning that vehicles can not be overloaded, otherwise, serious consequences can be caused. Moreover, without being artificially controlled, the invention can achieve the satisfactory effect of automatically cautioning and punishing the overloaded vehicles as long as the maximum loading capacity is preset, thus having favorable utility value and being easily popularized and applied.

Description

Technical field [0001] The invention belongs to a traffic road protection facility, and in particular relates to a road load limiter for limiting vehicle overload. Background technique [0002] In recent years, with the continuous and in-depth development of economic construction and reform and opening up, my country's transportation industry has also developed by leaps and bounds. However, due to vehicle overloading and rolling and the objective existence of the "tofu dregs project", newly-built roads are as long as three or five years, or as few as one or two years. The rework rate and repair rate are quite high, which is a waste of national funds. It also affects the efficiency of transportation. At present, traffic police often check for overload and overrun problems on some important traffic roads, but due to profit-driven operations, violations of rules and regulations still exist; some roads are also installed with overload inspection facilities, and traffic jams are ofte...

AI Technical Summary

Problems solved by technology

However, due to reasons such as overloaded vehicles and the objective existence of "tofu dregs projects", the newly built roads will be broken into pieces in three to five years at most, and in one or two years at least. The rework and repair rates are quite high, which is a waste of national funds. It also affects the efficiency of transportation

At present, the traffic police often check the problem of overloading and exceeding the limit on some important traffic roads, but due to the drive of interests, illegal operations still exist; some roads have also installed overloading inspection facilities, and traffic jams often occur during the inspection period, which seriously affects the normality of the road However, because of its complex structure, easy damage, and high procurement costs, it is not conducive to large-scale promotion and application.
