Unidirectional travel limiting device for roads and bridges

Abstract

The invention discloses a unidirectional travel limiting device for roads and bridges, comprising a base; A protective plate is nested around the chassis; A plurality of flow holes are symmetrically arranged on the left and right sides of the protection plate; Welding the fixture on the right side of the upper surface of the base; The fixing seat is connected with a limiting plate through a rotating shaft; The left side of the limiting plate is fixed with a second magnet, and the lower surface of the second magnet is fixed with a telescopic rod; A low end of that telescopic rod is nested in the sleeve; A baffle plate is transversely installed in the sleeve; A telescopic rod is fix above that baffle plate, and a second spring is arrange below the baffle plate; a first spring is fixed on a lower surface of the sleeve;a fixing bolt is installed on the surface of the protective plate; The fixing bolt penetrates the protective plate and is connected with the main arm; The right end of the driving arm is fixed with a driven arm through a connecting shaft; The left side of the protection plate is fixed with the lower frame; a first magnet is fixed on the right side wall of the lower frame; The invention has the advantages of simple structure and convenient operation, the vehicle is prevented effectively from traveling backwards, safe driving of the vehicle is ensured.

Description

technical field [0001] The invention relates to a road bridge device, in particular to a one-way traffic restriction device for a road bridge. Background technique [0002] In modern urban road planning, some one-way streets are often set up according to the needs of the actual situation. As the name implies, these one-way streets only allow vehicles to drive in one direction, and do not allow vehicles to drive in opposite directions. The design of the one-way street is conducive to ensuring traffic flow Smooth flow and traffic safety. [0003] In practice, observing the one-way street rules depends on the supervision of traffic staff or the good quality of the drivers. It does not rule out that some drivers who are in a hurry or do not understand the traffic rules go against the one-way street. At present, there is no good solution for this situation. The solution is to rely on supervision and electronic photography. Fines, but these methods can only be dealt with after t...

Problems solved by technology

Fines, but these methods can only be dealt with after the event. Only violations or even traffic accidents can be dealt with according to the law. The symptoms are not cured. If you want to stop it fundamentally, you must prevent it in advance to prevent the occurrence of one-way vehicles that violate regulations. Therefore, it is necessary to design One-way traffic restriction device for road bridge
