Convenient temporary bridge

Abstract

A convenient temporary bridge comprises legs, walking devices, a main bridge, a front auxiliary bridge, a rear auxiliary bridge and a reeling mechanism. The legs are mounted at lower sides of four corners of the main bridge; the waling devices, each comprising a nut block, a support, a lead screw, a lead screw head, a wheel fork and a wheel,are mounted on the legs respectively; the wheels can be lifted and the legs land on the floor when the temporary bridge is used for transport service; the wheels lands on the floor and the legs are lifted when the temporary bridge moves. The reeling mechanism comprises a motor, a reel, a pull rope and a bracket. The rear auxiliary bridge is hinged to the rear end of the main bridge, the front auxiliary bridge is hung on the front end of the main bridge.After the front auxiliary bridge is detached, the front of the main bridge is pulled by the motor, the reel and the pull rope of the reeling mechanism, the legs in the rear of the main bridge are pushed to the position beside obstacles while the legs in the front of the main bridge span the obstacles and then land on the floor; further, the front auxiliary bridge is connected by hanging; thus, the bridge can be used for transport service. In the process of folding, the rear auxiliary bridge is turned over and placed on the main bridge, the front auxiliary bridge is disposed on the topmost layer of the main bridge, and thus, the temporary bridge is folded and can be carried away by a trailer.

Description

technical field [0001] The invention belongs to the field of construction equipment, in particular to a convenient temporary bridge frame. 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 disadvantages of vehicles being impassable in the existing road construction, and provide a new type of bridge equipment, especially a convenient temporary bridge, hereinafte...
