but current city ground railway bridge is at the in-process that uses, and both sides lack protection machanism, lead to the rubble at railway top to splash easily, influence the driving safety of below, and the railway in-process of traveling, the noise on the below road surface is great, influences driver's normal driving, consequently, the utility model provides a problem that exists in order to solve prior art in city ground railway bridge.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims at providing a city ground railway bridge to solve the problem that can't protect the railway bridge among the prior art.

The purpose of the utility model can be achieved by adopting the following technical scheme:

the utility model provides a city ground railway bridge, includes the pier, the top of pier is provided with the bridgeplate, and the inboard at bridgeplate top is fixed with the crane span structure, rotate between crane span structure top and the bridgeplate and install the bull stick, and all be fixed with the baffle on the bull stick, the one end symmetry of bridgeplate is provided with the control box, and the internally mounted of control box has the motor, the driving gear is installed to the output of motor, driven gear is evenly installed to the inside both sides of bridgeplate, driven gear and bull stick fixed connection, the outside meshing of driving gear and driven gear has the rack, the intermediate position department at bridgeplate top is provided with the rail.

Preferably: and a rubber cushion block is fixed between the top of the pier and the bridge plate.

Preferably: fixed blocks are fixed on the outer sides of the piers, and springs are arranged between the tops of the fixed blocks and the bridge plates.

Preferably: the partition board is made of a sound insulation board.

Preferably: sealing strips are arranged on two sides of the partition board.

Preferably: the driving gear and the driven gear are the same in size.

The utility model has the advantages that:

the utility model provides a pair of city ground railway bridge, the setting of the inside motor of control box, the cooperation driving gear, the rack, driven gear and bull stick, the baffle uses, make the railway bridge at the in-process that uses, the protection to the railway bridge has been improved, and the rotation that can control the baffle wantonly, the convenience falls and rubble check keeps off at the in-process that the train travel, the security of railway bridge has been improved, in addition when the train is obstructed, the rotation of control baffle, can make things convenient for the inside ventilation of railway bridge, the practicality has been improved, the setting of pier bottom spring and rubber cushion, can improve the damping performance of railway bridge and to reduce the impact force to the pier, the practicality is higher.
