The invention discloses a rear outrigger device of a bridge erecting machine and relates to the technical field of bridge engineering construction equipment. The invention comprises a beam, an outer support leg and an inner support leg, and the outer support leg and the inner support leg are respectively hinged with the cross beam; the outer support leg is provided with an outer folding oil cylinder and an outer support oil cylinder; The support cylinder is equipped with an anti-tipping mechanism at the bottom of the inner outrigger. The present invention is supported on the beam carrier by the outer outriggers, the force is uniform and reasonable, safe and reliable, and the safety and stability of the bridge erecting machine are enhanced; the folding and support of the entire rear outriggers are realized by the oil cylinder, and the operation is simple and can realize erection The fast beam feeding condition at the end of the bridge crane improves the efficiency of the bridge erecting machine during construction; the inner leg is equipped with an anti-tipping mechanism, which increases the safety of the bridge erecting machine; at the same time, the structure is simple and compact, easy to disassemble, transport and install. Maintenance, low cost, conducive to promotion.
Description
technical field [0001] The invention relates to the technical field of bridge engineering construction equipment. Background technique [0002] The bridge erecting machine is the equipment that places the prefabricated girders on the prefabricated bridge piers. Compared with traditional construction methods, bridge erecting machine construction has high construction efficiency, safety and reliability, so it has been widely used in highway and railway bridge construction. Since the main function of the bridge erecting machine is to lift the beam, and then transport it to the position and put it down, it belongs to the category of cranes, but it is very different from the crane in the general sense, because the bridge erecting machine often walks on the beam and other high altitudes Operating conditions, so the requirements for the bridge erecting machine itself are very strict. For the construction of large-tonnage double-line bridges, after considering the construction req...
