A kind of mobile overpass bridge

Technical field

The utility model relates to a kind of mobile overpass bridge.

Background technology

All be provided with traffic lights at present on the crossroad of a lot of roads, vehicle must stop when red light, waits for the green light clearance.In the more big and medium-sized cities of vehicle, vehicle is discharged to next crossing from this crossing, and the speed of a motor vehicle is lower than 5 kilometers, and the traffic congestion phenomenon often takes place, and is if set up nonvolatil cement concrete viaduct cost height at the parting of the ways, long in time limit.Now also there is not a kind of instrument that can solve crossroad traffic congestion phenomenon fast.

The utility model content

The technical problems to be solved in the utility model provides a kind of mobile overpass bridge, uses this mobile overpass bridge to form quick overpass bridge form to solve the traffic congestion phenomenon.

For solving the problems of the technologies described above, the road wheel that the mobile overpass bridge that is provided comprises underframe and is installed on the underframe and driven by power set, its design feature is: the bracing or strutting arrangement that can stretch down is housed on the underframe, the fixed bridge body that column is housed on the underframe and is obliquely installed, this mobile overpass bridge also comprises the slippage pontic that is slidingly mounted on the column and can tilts to be connected as a single entity to same direction with fixed bridge body after the slippage, and the slippage pontic is driven by the slippage drive unit.

After adopting said structure, when the traffic congestion phenomenon takes place at the crossing when, can drive this mobile overpass bridge by power set is in the middle of the crossing, drive the underframe rising by stretching under the bracing or strutting arrangement, driven slippage pontic slippage and made it to be connected as a single entity with fixed bridge body by the slippage drive unit, the place is provided with two this mobile overpass bridges altogether at the crossing, and two move overpass bridge butt joint formation overpass bridge fast, vehicle can be gone up this overpass bridge by the crossing, and vertical current vehicle with this overpass bridge can pass through from the underframe below; After the traffic congestion phenomenon solves, the slippage pontic can be packed up, underframe is removed by power set got final product.In sum, the utility model can form overpass bridge fast, and to solve of short duration traffic congestion phenomenon, cost is low, the duration is short, can handle the traffic congestion phenomenon at different crossings flexibly.

The slideway that is obliquely installed is housed on the column, the travelling carriage that cooperates with slideway is housed on the slippage pontic.

Described fixed bridge body comprises support column that is packed on the underframe and the fixedly bridge plate that is packed on the support column.

Described bracing or strutting arrangement is the oil cylinder that is installed on the underframe.

Described slippage drive unit comprises support cylinder that is installed on the underframe and the drawing oil cylinder that is installed on the column.

The slippage pontic is made as the preceding pontic of slippage forward and two sections of the back pontics of slippage backward altogether.

The front end of the rear and front end of preceding pontic and fixed bridge body and back pontic all is equipped with junction plate, connects by bolt between the two adjacent junction plates.Being provided with of junction plate and bolt is beneficial to fixed bridge body and forward and backward pontic connects as one, and plays the effect of reinforcing.
