Abstract

The invention provides a track beam emergency repairing and replacing system, by the adoption of the system, a whole set of rapid and efficient emergency response methods can be provided aiming at a damaged track beam. The track beam emergency repairing and replacing system comprises a track beam emergency repairing and replacing command center, a damaged track beam evaluating and removing system, an emergency track beam material storage and optimum selection system, an emergency track beam prefabricating and assembling system, an emergency track beam transporting and erecting system and an emergency track beam operation period monitoring system. The track beam emergency repairing and replacing system can achieve rapid replacing of the damaged track beam, recover operation of single track transportation and reduce the social impacts caused by the damaged track beam to the minimum level.

Description

technical field [0001] The invention relates to a straddle-type monorail traffic system, which is applied to the emergency repair and replacement of damaged track beams in the civil engineering of the straddle-type monorail traffic system, in particular to the emergency repair and replacement system of the straddle-type monorail traffic system. Background technique [0002] The most notable feature of straddle-type monorail traffic is that the vehicle directly rides on the track beam and runs quickly. The track beam is not only a load-bearing structure, but also a guiding structure. It must guide the operation of the train; it must not only meet the structural load-bearing requirements, but also form the track alignment according to the line design requirements during the manufacturing and erection process. As the running track of light rail vehicles, the track beam is directly related to the safety and smoothness of the train during operation, and the requirements for its d...
