Rotatable open type height limiting frame for intelligent traffic

Abstract

The invention relates to the technical field of height limiting frames, and discloses a rotatable opening type height limiting frame for intelligent traffic, which comprises a fixed plate, a movable plate is arranged in the fixed plate, the outer surface of the movable plate makes contact with the side wall of an inner cavity of the fixed plate, an adjusting device is arranged in the fixed plate,and a fixed shaft is fixedly connected to the upper surface of the movable plate. The top end and the bottom end of the outer side wall of the fixing shaft are fixedly connected with ball bearings, and the outer side walls of the ball bearings (5) are fixedly connected with connecting rings. According to the rotatable open type height limiting frame for intelligent traffic, through the cooperationeffect of a first servo motor, a rotating shaft, a stabilizing plate, a gear, a rack, a fixed plate and a movable plate, the height of the height limiting frame can be adjusted; and through the cooperation of a second servo motor, a transmission shaft, a first chain wheel, a second chain wheel, a chain, an auxiliary ring, a connecting ring, a ball bearing, a fixing shaft and a fixing block, the height limiting frame can be controlled to rotate by a certain angle, and the adaptability is improved.

Description

technical field [0001] The invention relates to the technical field of overhead limiters, in particular to a rotatable open type overhead limiter for intelligent transportation. Background technique [0002] At present, the limited viaduct is mainly used for the portal frame 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. It is suggested to the vehicle that the existing smart traffic overhead limit can not be adjusted in height, which increases the limitation of the use of the overhead limit. [0003] In China Patent Publication No. CN107724286A, an adjustable road overhead limiter for road construction is disclosed. The adjustable road overhead limiter for road construction needs to adjust the height of the overhead limiter by controlling the driving mechanism manually, but this method There are great defects: the device requires a certain amount of labor to adjust ...
