Description

Lifting type intersection safety protection mechanism

Technical Field

The utility model relates to a protection mechanism specifically says so and installs before the stop line of road, is used for carrying out the over-and-under type crossing safety protection mechanism that protects the pedestrian of crossing zebra crossing.

Background

As is known, in cities, a large number of motor vehicles and non-motor vehicles are kept on a lane, and in order to facilitate pedestrians to pass through the lane, zebra crossings are arranged on the lane.

At present, the zebra crossing on the road is used together with a vehicle stop line and a signal lamp, namely when a red lamp of a lane signal lamp is on and a green lamp of the zebra crossing signal lamp is on, the vehicle stops in front of the lane stop line, and pedestrians can safely pass through the zebra crossing. When the green light of the signal light in the lane is bright and the red light of the zebra crossing signal light is bright, the pedestrian stops in front of the zebra crossing stop line, and the vehicle can normally pass through the zebra crossing. However, the stop line only serves as an indication function, and in actual use, vehicles (particularly non-motor vehicles) still violate regulations, and when the red light of a lane signal lamp is on, the stop line is crossed, so that the personal safety of pedestrians is threatened. Simultaneously, also can have the pedestrian and violate the regulation when in actual use, when the red light of zebra crossing signal lamp is bright, steps on the zebra crossing, influences the normal traffic of vehicle, and causes the traffic hidden danger. In addition, when road blocking inspection is needed, law enforcement personnel need to move the stop posts to be placed on the road to achieve road blocking, and after the road blocking inspection is finished, the stop posts are moved away so that vehicles can pass through the road blocking inspection, and the work efficiency is low.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide an over-and-under type crossing safety protection mechanism, adopt this safety mechanism can eliminate the threat of personal safety, guarantee that the vehicle normally passes, avoid the traffic hidden danger, the work efficiency of checking of blocking the road is higher.

In order to solve the problems, the following technical scheme is provided:

the utility model discloses an over-and-under type crossing safety protection mechanism's characteristics are including the casing, and the top of this casing is uncovered form, has lift platform in the casing, and lift platform's top has vertical arrangement's the pole that blocks, when lift platform is in the extreme low position, blocks that the pole is located the casing, when lift platform is in the highest position, blocks that the pole stretches out outside from the uncovered department of casing.

When the device is used, the protection mechanisms are embedded in the outer sides of the zebra crossing stop line and the lane stop line, the lifting platform is connected with a traffic power box of a road, and the lifting platform is controlled to run by a control unit of a signal lamp on the road. When the red light of a lane signal lamp is on and the green light of a zebra crossing signal lamp is on, the lifting platform of the protection mechanism in the lane is lifted, the blocking rod extends out of the ground and blocks the automobile from passing through, so that the automobile cannot approach or enter the zebra crossing; the lifting platform of the protection mechanism in the zebra crossing descends to block the rod from entering the ground so as to facilitate the passage of pedestrians. When a green light of a lane signal lamp is on and a red light of a zebra crossing signal lamp is on, the lifting platform of the protection mechanism in the lane descends, and the blocking rod enters the ground so that an automobile can pass through the lifting platform; the lifting platform of the protection mechanism in the zebra crossing is lifted, and the blocking rod extends out of the ground to block pedestrians from entering the zebra crossing. Therefore, the safety protection mechanism can prevent vehicles from passing through the stop line and approaching or entering the zebra crossing when the red light of the signal lamp is on and the vehicles violate the regulations, thereby eliminating the safety threat caused by the pedestrians and the vehicles when the pedestrians cross the road, particularly blocking the non-motor vehicles and ensuring that the situation that the pedestrians cross the road when the non-motor vehicles run the red light can not occur. Meanwhile, pedestrians can be prevented from entering the zebra crossing contrary to regulations, vehicles can be guaranteed to normally pass, and traffic hidden troubles are avoided. In addition, when road blocking inspection is needed, law enforcement workers can control the blocking rod to extend out of the ground through the control unit of the signal lamp and block the road, after the road blocking inspection is finished, the control unit of the signal lamp controls the blocking rod to descend to the ground, vehicles can normally pass, and the working efficiency of law enforcement personnel is greatly improved.
