Automobile overload detecting device for bridge

Abstract

The invention discloses an automobile overload detecting device for a bridge. The device comprises a foundation; a groove is formed in the upper surface of the foundation; a device box is installed inthe groove; a mounting hole is formed in the upper surface of the device box; a plurality of springs are evenly mounted on the inner bottom wall of the device box; the the upper ends of the pluralityof springs are jointly welded to a carrying plate; two unidirectional racks are symmetrically welded onto the lower surface of the carrying plate; two first mounting seats and two second mounting seats are symmetrically welded in the device box; each first mounting seat is coaxially provided with a small sprocket and a winding roller; each second mounting seat is coaxially provided with a large sprocket and a straight spur gear; and each large sprocket and the corresponding small sprocket are jointly sleeved with a roller chain. The automobile overload detecting device for the bridge of the invention has the advantages of ingenious structure and convenient use. According to the automobile overload detecting device for the bridge of the invention, the length of a connection rope released by the winding roller can be increased through a simple mechanical structure; and a gate rod can block an overload automobile by means of the gravity of the gate rod itself.

Description

technical field [0001] The invention relates to the technical field of bridge safety, in particular to an automobile overweight detection device for bridges. Background technique [0002] With the development of our country's transportation, the health and maintenance of bridges are increasingly concerned by people. Each bridge is designed to limit the maximum weight of a single vehicle on the bridge, and the damage to the bridge caused by overweight passenger vehicles on the bridge is the primary problem affecting the health and service life of the bridge. The light ones cause internal damage to the bridge body, and the heavy ones Otherwise, it will lead to the collapse of the bridge, causing great economic losses and casualties. [0003] Most of the existing bridges do not have an overweight detection mechanism, so it is difficult to determine whether the vehicle is overweight when it is on the bridge, which is likely to cause bridge safety hazards. [0004] For this rea...
