Abstract
An adjustable vehicle width-limiting device comprises a width-limiting pier. A cavity communicated with the exterior is formed in the width-limiting pier. A moving block is arranged in the cavity and can move to the exterior of the width-limiting pier along the cavity. A screw transmission mechanism is arranged in the width-limiting pier, and a transmission component in the screw transmission mechanism is connected with the moving block. In the use process, the adjustable vehicle width-limiting device and an existing width-limiting pier are oppositely installed on the entry of a levee crown road at an interval. When a large lorry is approved to enter the levee crown road, a starting device is started, the screw transmission mechanism moves the moving block into the cavity of the width-limiting pier, and therefore the large lorry can pass through the levee crown road. According to the adjustable vehicle width-limiting device, the width-limiting distance can be easily changed, it only needs to retract the moving block into the width-limiting pier without disassembling the adjustable vehicle width-limiting device when the large lorry needs to pass through the levee crown road, and therefore management is convenient, the workload of management personnel is relieved, and the cost is lowered. The adjustable vehicle width-limiting device is simple in structure and convenient to use.
