Beam replacement equipment support leg and beam replacement equipment

Abstract

The application relates to the technical field of bridge beam replacement, and provides a beam replacement equipment support leg and a beam replacement equipment. The beam replacement equipment support leg comprises a bottom support structure, a bottom cross beam, a telescopic support leg, an upper cross beam, a lifting column system, a rotating system and a telescopic system, the bottom cross beam is rotatably connected to the bottom support structure; the lower end of the telescopic support leg is fixedly connected with the bottom cross beam, and the upper end of the telescopic support leg is fixedly connected with the upper cross beam; the lifting column system is arranged on the upper cross beam, and the upper cross beam is used for being rotatably connected with a main beam through the lifting column system; the rotating system is in transmission connection with the lifting column system or the upper cross beam, and is used for driving the upper cross beam, the telescopic support leg and the bottom cross beam to rotate relative to the bottom support structure; and the telescopic system is in transmission connection with the telescopic support leg, and is used for driving the telescopic support leg to elongate or contract. When the beam replacement equipment needs to be transported, the overall height and width of the beam replacement equipment support leg can be reduced through the telescopic system and the rotating system, so that the whole beam replacement equipment can smoothly pass through a tunnel, and the beam replacement efficiency is improved.
