Abstract

The invention relates to an emergency bridge installed with an excavator. The bridge comprises a foot-column mechanism, a double-hinge structure, a main bridge, a front auxiliary bridge and a rear auxiliary bridge. A leg mechanism is instal at that lower side of the four corners of the main bridge frame. A walking device consist of a nut block, a screw rod, a screw rod head, a wheel fork and wheels arranged on that side of the leg post. Wheel are height adjustable. When the bridge is opened to traffic, the legs touched the ground and the wheels were raised. When the bridge was pulled away, thewheels touched the ground and the legs were raised. When installing, use excavator bucket of construction site to lift the main bridge frame and place it on the ditch and slag ridge in road construction. Use the excavator bucket to lower the rear auxiliary bridge frame and the front auxiliary bridge frame from the main bridge frame and place one end on the ground respectively, so that the vehiclecan be opened to traffic. When folding, use excavator bucket to lift the front and rear auxiliary axle frames and place them on the main axle frame to be towed away by trailer. The emergency bridge frame is used for installing the temporary bridge frame of the excavator when the road construction cannot be opened to traffic, so as to facilitate the passage of vehicles.

Description

technical field [0001] The invention belongs to the field of construction equipment, in particular to an emergency bridge installed by an excavator. Background technique [0002] In the present road installation pipeline construction, a ditch is often dug horizontally on streets and highways, and concrete and earth slag blocks are piled up into a slag ridge on the side of the ditch, making it impossible for vehicles to pass through. A large number of vehicles had to go around. Bring a lot of inconvenience to passing vehicle. Although some construction sites temporarily put a bridge frame on the ditch, there is difficulty in crossing obstacles above the ground, and it is inconvenient to retract and move the bridge frame. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of vehicles being impassable in the existing road construction, and provide a new type of bridge equipment, especially an emergency bridge installed by...
