Abstract

The invention provides a middle support bracket system of a bridge girder erection machine, which is mounted in the middle of the bridge girder erection machine and comprises a middle support leg joist, a main beam longitudinal movement driving mechanism and a transverse walking mechanism, and the main beam longitudinal movement driving mechanism and the transverse walking mechanism are respectively arranged on the upper side and the lower side of the middle support leg joist. The girder longitudinal movement driving mechanism is arranged at the bottom of the girder of the bridge girder erection machine and used for driving the girder to move longitudinally, and the transverse walking wheel box is connected with the middle supporting leg joist and can be used for driving the middle supporting leg joist to move in the transverse bridge direction. The middle of the main beam moves in the transverse bridge direction through the transverse walking mechanism, and the purpose of adjusting the transverse position of the main beam can be achieved. In addition, the position of the front end of the main beam can be limited, the main beam can rotate around the front end of the main beam, the middle of the main beam is pushed through the transverse walking mechanism so that the main beam can rotate around the front end of the main beam, then the angle of the main beam is adjusted, and the construction requirement of the oblique crossing bridge is met.

Description

technical field [0001] The present application relates to the field of bridge construction, in particular to a center support system of a bridge erecting machine. Background technique [0002] The bridge erecting machine lifts the girders, then transports them to the position and puts them down. It is a bridge construction machine that travels on roads and railway tracks and is used to erect small span girders across the entire span. Its fuselage is huge and exceeds the limit of railway transportation, so it must be disassembled and transported, and then assembled and used after arriving at the construction site. [0003] The high-speed railway passenger dedicated line passes through mostly mountains and rivers with complex terrain, and there are many bridge-tunnel connecting sections, and the traveling angle of the bridge erecting machine needs to be changed between the connected sections to adapt to the complex terrain, but now bridge erection Changing the angle of the ma...
