Description

Tram's pedestrian safety protection mechanism that passes through

Technical Field

The utility model belongs to the tram field, more specifically relates to a tram's pedestrian safety protection mechanism that passes.

Background

Trams are light rail transit vehicles that are electrically driven and travel on rails. The tramcar is a public transport means, also called road tramcar, short for tramcar, belong to a kind of light railway, the tramcar generally does not exceed five sections, its existing density of bus station, can have the specialized orbit of the train too, guaranteed certain transport capacity at the same time, and avoid rationally in the place that may hinder the pedestrian traffic, and have not high cost, mainly have the following advantages:

1) and (4) safety. Due to the constraint of the track, the probability of serious accidents caused by misoperation of drivers is lower than that of vehicles without the track, and particularly, the probability of passenger casualty accidents is not much lower than that of vehicles with the track. The probability of injury to the passenger is low even in collisions with other vehicles.

2) Environmental protection and zero emission. Even with only the transfer of pollutants, it is far better to discharge the pollutants directly into populated areas, on the breathing zone of pedestrians (especially children). And the zero emission vehicle is more suitable for running in the tunnel. In addition, the energy consumption of the wheel-rail vehicle is lower than that of a rubber-tyred vehicle.

3) The operation cost is low. The electricity consumption is cheaper than oil burning, and the maintenance of the vehicle is simpler than that of the automobile. Although the vehicle purchase cost is high, the service life is far longer than that of a bus. Compared with a pure electric bus using batteries, the method saves expensive battery cost and does not need to build a charging station.

4) Compared with an automobile, the automobile has good acceleration, deceleration and climbing performances. The series excited direct current motor or the variable frequency alternating current motor has good traction characteristics, does not need a gearbox, and has higher efficiency under the conditions of different speeds and different loads. The brake can realize regenerative braking, save energy, reduce the abrasion of the brake pad and ensure that the vehicle runs more stably and comfortably. Therefore, the tramcar is particularly suitable for the working conditions of frequent start and stop and multi-ramp, and the efficiency and the emission of the car are high under the working conditions.

Tramcars are currently used in many cities in China. However, as the tramcar runs on the city street and occupies the road space, the tramcar track inevitably intersects with the city road, and at some intersected intersections, security personnel are arranged at the intersections of many cities to perform security prevention and control manually at present, so that safety accidents caused by the fact that pedestrians or vehicles pass through the tramcar track when the tramcar arrives are prevented. When a wider road intersects with a tramcar track, due to the fact that the width of the wider road is larger, a plurality of safety personnel are often required to be arranged for prevention and control, the operation cost of the tramcar is undoubtedly increased, all pedestrians and vehicles are difficult to prevent, safety risks still exist, and particularly under the condition that the sight is poor or the safety personnel are tired at night, the safety risks are higher. If the traditional rotatable and liftable railings are arranged on a wider road, the railings need to be longer, and the opening and closing of the railings are slow, so that the passing of people and vehicles on the wider road is seriously influenced.

SUMMERY OF THE UTILITY MODEL

To the above defect of prior art or improve the demand, the utility model provides a tram's pedestrian safety protection mechanism that passes through, it is through setting up photoelectric protector on the road, can prevent effectively that when the tram stops a station, the pedestrian passes the tram track to the security has been improved.

In order to achieve the above purpose, according to the utility model, a pedestrian passing safety protection mechanism of a tramcar is provided, which is characterized in that the mechanism comprises a track circuit, two photoelectric protectors, two portal frames and two groups of loudspeaker, wherein,

the tramcar track is positioned between the two photoelectric protectors;

each photoelectric protector comprises a light emitter and a light receiver, and light emitted by the light emitter is directly emitted to the light receiver to form a protective light curtain;

each portal frame comprises two upright posts and a cross beam jointly borne by the two upright posts;

each portal frame is provided with one photoelectric protector, and a light emitter and a light receiver of each photoelectric protector are arranged on one upright post respectively;

and a group of sound amplifying horns are respectively arranged on the beam of each portal frame.

Preferably, the portal frame is made of stainless steel.

Preferably, a protective cover is arranged on the periphery of each photoelectric protector, and the protective cover is installed on the portal frame.

Preferably, each loudspeaker's periphery all is provided with the protection casing, the protection casing is installed on the portal frame.

Preferably, the public address horn is a waterproof horn.

Preferably, an alarm is arranged on the cross beam of each portal frame and used for giving out warning sound.

Generally, through the utility model discloses above technical scheme who conceives compares with prior art, can gain following beneficial effect: the track circuit of the utility model can detect whether the position of the tramcar corresponding to the platform is occupied by the tramcar, thereby controlling the opening and closing of the photoelectric protector, opening the photoelectric protector when occupied, and closing the photoelectric protector when not occupied; and the utility model discloses a two photoelectric protector sets up respectively in the orbital both sides of tram, can prevent effectively that pedestrian and vehicle from crossing the tram track. Whether this region has pedestrian and vehicle is surveyed to the protection light curtain that photoelectric protector formed, has guaranteed personnel's safety and the driving safety of crossing department, and public address loudspeaker also can send the warning words in addition and warn the pedestrian, has further ensured the safety of pedestrian and vehicle.
