Novel middle supporting device of large-tonnage bridge girder erection machine
The invention provides a novel middle supporting device of a large-tonnage bridge girder erection machine. The novel middle supporting device comprises a front supporting leg and a rear supporting leg located behind the front supporting leg. The front supporting leg comprises a front supporting leg upper beam. The left side and the right side of the bottom face of the front supporting leg upper beam are each connected with a supporting piece in a rotating mode through a corresponding front hinge. The left side and the right side of the top face of the front supporting leg upper beam are each provided with a front sliding way in the left-right direction. The front sliding ways are internally connected with front trays in a sliding mode. The front supporting leg upper beam is provided with front transverse moving drive oil cylinders for driving the front trays to slide along the corresponding front sliding ways, and the front trays are provided with front carrier roller supporting mechanisms. The novel middle supporting device can meet the erection requirement of camber beams, can meet the special working condition of double-amplitude box girder center distance change and can meet the extremely special working condition that a bridge face on one side is supported, and a pier on one side is supported as well. The application range of the bridge girder erection machine is greatly expanded, various girder erection requirements can be better met, meanwhile the overall weight of the bridge girder erection machine is reduced, and the manufacturing cost and the investment cost of equipment are saved.
