Description

Automatic lifting roadblock for preventing overload hazard

Technical Field

The invention belongs to the technical field of municipal facilities, and particularly relates to an automatic lifting roadblock for preventing overload hazards.

Background

In urban construction, for some ancient bridges with milestone significance and local customs culture correlation, governments usually repair and protect the ancient bridges without blasting and disassembling the ancient bridges. Although these ancient bridges can be used for traffic, the bearable vehicle weight is not as high as that of newly constructed bridges due to the fact that the number of years is too high. Once an overweight cart drives into an ancient bridge, the ancient bridge is damaged due to the fact that the weight of the ancient bridge exceeds a bearing limit, a bridge road collapses if the ancient bridge is light, and the ancient bridge is broken and collapses if the ancient bridge is heavy, so that the damage of municipal facilities, the consumption of government financial resources, the jam of traffic states, the damage of vehicles, the casualties of people, the damage of environments and the like are caused by direct consequences.

Therefore, we must restrict the drive of the overweight cart into the old bridge. Usually, a traffic bureau can erect a mark at a bridge entrance and mark the value of the upper limit of the load of the ancient bridge.

However, in actual life, a part of the large trucks drive into the old bridge to approach the road, or the load capacity is increased to reduce the transportation cost, so that the old bridge bears the weight exceeding the upper limit of the load capacity, and the road of the old bridge is damaged.

There are also owners of large vehicles carrying goods, who are not aware of the weight of the carried goods of the driven vehicles, and who unintentionally carry too heavy goods into the old bridge, which causes damage to the old bridge.

In order to avoid the situations in some areas, automatic side-weighing devices and road-blocking railings are built at the entrances of ancient bridges by cutting once, so that normal vehicles need to be on side to enter and exit, and are blocked by the road-blocking railings, and the passing efficiency is reduced; and in severe cases, traffic jam can be caused.
