Emergency Bridge Frame in Construction

Abstract

The invention relates to an emergency bridge under construction.The emergency bridge under construction includes a foot column sleeve,a foot column, a wheel lifting mechanism, a hydraulic cylinder, amain bridge frame, a front auxiliary bridge frame, a rear auxiliary bridge frame and ra etracting mechanism. At that low side of the four corners of the main bridge frame, foot post sleeve are installed. The foot post and the hydraulic cylinder are installed in the foot post sleeve. The foot board under the foot post is connected with the wheel lifting mechanism, so that the foot post touches theground when the bridge is open to traffic; When the bridge is moved, the wheels land and the legs are raised. The rear auxiliary bridge frame is hinged at the rear end of the main bridge frame, and the front auxiliary bridge frame is hung at the front end of the main bridge frame. Remove the front auxiliary bridge frame, pull up the front of the main bridge frame with the motor of the retracting and releasing mechanism, twisting wheels and pulling ropes, push the rear foot pillar of the main bridge frame to the side of the obstacle, and the front foot pillar crosses the obstacle and falls. Hang on to the front sub-axle frame and you can open to traffic. When folding, turn the rear auxiliary bridge frame onto the main bridge frame and put the front auxiliary bridge frame on the top of the main bridge frame so that the frame can be pulled away by trailer.

Description

technical field [0001] The invention belongs to the field of construction equipment, in particular to an emergency bridge during construction. 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 during existing road construction, and provide a new type of bridge equipment, especially an emergency bridge during constructio...
