The bridge includes four columns, and an overbridge plate which is fixed in the middle of the four columns, a platform plate which is mounted at the top of the columns. A roller wheel is mounted at the bottom of each column. The lower parts of the two columns on the same side of the street is connected by a crossbeam. The lifting jacks are fixed on the both sides of the crossbeam. The support devices are provided among the overbridge plate, the crossbeam and the lower parts of the two columns on the same side of the street. They are also provided among the overbridge plate, the platform plate and the upper parts of the columns. A power equipment is mounted on the crossbeam. The power equipment includes a motor, and a gearbox is connected with the motor by an output shaft of the motor. The output shaft of the gearbox is connected with the roller wheels by a chain drive. A control unit is connected with the motor. The control unit includes a data processing unit, and a video capture device and a data acquisition and analysis unit which are connected to the data processing unit respectively. The overbridge system can be moved automatically. The overbridge system can be moved to the crossing as required, thus significantly alleviating the traffic pressure. |
