Intelligent Highway Elevation Limit

Abstract

The invention discloses an intelligent road height restriction frame. The intelligent road height restriction frame comprises a portal frame, at least one lifting component and at least one electronic control device, wherein at least one lifting component is fixedly arranged on the portal frame; each lifting component comprises a motor, a speed reducer, a converter, a leading screw and nut mechanism, a shearing knife and fork, a lifting rod and a height restriction rod; the motor drives a leading screw of the leading screw and nut mechanism to rotate by virtue of the speed reducer and the converter; the upper end of the shearing knife and fork is connected with a nut of the leading screw and nut mechanism, and the lower end of the shearing knife and fork is connected with the lifting rod through a sleeve; the height restriction rod is connected with the lifting rod; and at least one electronic control device is mutually and electrically connected with at least one lifting component one by one and used for controlling the motor to rotate forward and reversely. The intelligent road height restriction frame disclosed by the invention is simple in structure, the height of the height restriction frame is adjustable, and intelligent adjustment can be realized by virtue of the electronic control device and the motor, so that manpower and material resources which are invested for road control are effectively reduced.

Description

technical field [0001] The invention relates to an intelligent road height limiter. Background technique [0002] The current vehicle restriction can generally be realized through signs, markings, overhead restrictions and manual duty. The first two methods mainly rely on the driver's self-consciousness, and the enforcement is limited. The manual duty method is limited by manpower, time and other conditions. It cannot be realized in important time periods, and it is found by comparison that the method of limiting the height is the most economical and effective. [0003] Elevation-limited overpass is a portal frame used at the entrance of bridges, culverts, and tunnels. It is generally welded by steel structures and plays the role of protecting bridges, culverts, and tunnels; Cue the vehicle. At present, there are mainly three kinds of common height limit racks: fixed height limit racks, manual height limit racks, and electric height limit racks. Nowadays, the elevated via...

Problems solved by technology

[0004] At present, most of the height-limited highways in our country are fixed, and the height-limited height cannot be adjusted. If special circumstances or emergencies require super-high vehicles to pass, or the traffic is controlled by time, the current elevated-limited highway will become an obstacle.
