Tonnage Bridge Erector.
Background technique
Line for Passenger Transportation and high speed railway construction initial stage in China, the location of big multi-line are that economy is more flourishing coastal
Plains region, geographical conditions are preferable, are substantially all to bridge sweep in 5000m or more, and country's 900t box beam bridge formation
Machine is usually designed manufacture according to the adaptability of maximum conditions 2000m sweep.But with city track traffic engineering
Iterative method, inter-city passenger rail construction is maked rapid progress, due to being limited by objective condition, such as landform, urban road and building
Limitation reduces investment and reduces limitation of removing, while the modern design of beam type designed by city track traffic engineering, pier type,
Beauty, beam type is light, and the construction load that can be born is small, and plane curve is also smaller and smaller, and construction difficulty is increasing, therefore right
More stringent requirements are proposed for the technical performance of setting up girder.
So far, domestic 900t grades of railway whole opening box girder there is no the successful elder generation of the erection construction on 500m sharp radius curve
Example, railway whole opening box girder on 500m sharp radius curve is not satisfied in the technical performance of existing 900t grade transportation rack device both at home and abroad
It sets up and requires.Therefore, it is necessary to undergo technological transformation to meet the erection of railway whole opening box girder on sharp radius curve to transportation rack device,
Wherein, following technical problem is solved:
(1) it is asynchronous on the different tracks there are angle that rear support leg and auxiliary leg when Bridge Erector contraposition traveling are solved
Operation problem avoids or reduces to gnaw rail, derailment occurring；
(2) after solving guide girder machine via hole, front end, which can not be successfully, places problem in place；
(3) solution beam car feeding beam is carried asynchronous operation of the beam trolley on the different tracks there are angle on the back and is asked when around
Topic, avoids or reduces occur gnawing rail, derailment occurring；
(4) solve the problems, such as that carrying beam trolley on the back generates relatively larger transverse power by beam car and guide girder machine track linkage section.
