Emergency traffic light

Abstract

The invention discloses an emergency traffic light, and mainly relates to the field of road traffic facilities. The emergency traffic light comprises a bottom plate, a fixed pipe is arranged at one side of the surface of the bottom plate, and a supporting rod is arranged on the inner bottom surface of the fixed pipe. A screw rod is rotatably arranged at the top end of the supporting rod, a threaded sleeve is in threaded connection with the outside of the screw rod, and a sliding block sleeves one end, positioned in the fixed pipe, of the threaded sleeve. The sliding block is in sliding connection with an inner cavity of the fixed pipe, a driving mechanism is arranged outside the fixed pipe and penetrates through the fixed pipe to control the rotation of the screw, and a signal lamp is arranged at the end, located outside the fixed pipe, of the threaded sleeve. Walking wheels are arranged under the bottom plate, a hydraulic lifting rod is arranged in the middle of the bottom of the bottom plate, and a supporting plate is arranged at the bottom of the hydraulic lifting rod. The emergency traffic light has the beneficial effects that the emergency traffic light can be stably placed after being moved to a designated position, the height is adjustable, and the emergency traffic light is suitable for roads with complex pavements.

Description

technical field [0001] The invention relates to the field of road traffic facilities, in particular to an emergency traffic light. Background technique [0002] There are two kinds of traffic lights, which are called motor vehicle lights for motor vehicles, and usually refer to signal lights that are composed of red, yellow, and green (green is blue-green) three-color lights to direct traffic. When the green light is on, vehicles are allowed to pass. When the yellow light is flashing, vehicles that have crossed the stop line can continue to pass; those who have not passed should slow down to the stop line and stop and wait. When the red light is on, vehicles are prohibited from passing. The ones shown to pedestrians are called crosswalk lights, which usually refer to the signal lights composed of red and green (green is blue-green) two-color lights to direct traffic. The red light stops and the green light goes. [0003] At some road intersections that have just been built,...

AI Technical Summary

Problems solved by technology

[0003] At some road intersections that have just been built, the regular traffic lights have not yet been officially put into use. In order to ensure the orderly driving at this intersection, a temporary emergency traffic light is usually set up to ensure the orderly passage and safety of vehicles at the intersection. At the intersections around the site, some traffic arteries, if closed, will seriously affect the surrounding traffic, so only simple access roads can be opened up, and this kind of intersections, because of the surrounding construction sites, the roads have not yet been fully constructed, so it is impossible to If formal traffic lights are set up, only movable emergency traffic lights can be used. However, the current emergency traffic lights cannot be placed in a fixed position due to the pulleys at the bottom, which will occur during the vibration of passing vehicles. The position is moved, and the height of the existing emergency traffic lights is mostly fixed. For some areas with height differences, the traffic lights with fixed heights are not easy to be observed in the distance, and are prone to danger.
