Abstract

The invention relates to the technical field of bridge frame changing, and particularly relates to a beam changing method with a foldable beam changing machine. The method comprises the steps that 1,a first beam conveying special train, a guide beam with a lifting function and a second beam conveying special train enter an area in sequence, a containing part is arranged on the guide beam, and a lifting hydraulic rod is hinged into the containing part; 2, the lifting hydraulic rod is controlled to extend so as to jack the guide beam; 3, the lifting hydraulic rod is controlled to contract, andthe lifting hydraulic rod is stored in the containing part again; 4, an old beam is hoisted to the first beam conveying special train by utilizing a pair of beam hoisting trolleys matched with two beam carrying trolleys on the first beam conveying special train; and 5, the pair of two beam hoisting trolleys is used for being matched with the two beam carrying trolleys on the second beam conveyingspecial train to lift a new beam to a to-be-replaced frame hole position. Rapid switching of the working states of the guide beam can be achieved through the lifting hydraulic rod and the containing part so that the construction efficiency is effectively improved, and the investment of mechanical equipment is effectively reduced.

Description

technical field [0001] The present disclosure relates to the technical field of bridge frame replacement, in particular to a beam replacement method with a foldable beam replacement machine. Background technique [0002] At present, with the rapid development of my country's transportation, the load capacity and speed of trains running on railways and cars running on roads have increased, the operating hours of railways and roads have increased, and the problem of aging bridges on existing lines has become increasingly prominent. In order to meet the normal operation of railways and highways and solve the problems of increased load capacity and limited speed of trains, it is necessary to replace bridges on existing lines. [0003] The beam changing methods of existing lines in my country at present include: using bridge erecting machines, gantry cranes to change beams and brackets to move beams laterally. Use the bridge erecting machine to change the girder, and the girder ...
