The invention relates to the technical field of bridge construction, and discloses a hoisting device for viaduct steel-concrete composite beam construction, which comprises a main body and a sliding chute, the sliding chute is formed in the right side of the main body, the hoisting device further comprises an expansion mechanism, the expansion mechanism is arranged in the sliding chute, the expansion mechanism comprises an expansion plate, and the expansion plate is slidably connected in the sliding chute; an abutting plate is fixedly connected to the left side of the expansion plate, and two air cylinders are fixedly connected to the side, away from the expansion plate, of the abutting plate and symmetrically distributed with the abutting plate as the center. When the size of the telescopic frame is large and the hoisting weight is large, the phenomenon that the device collapses forwards is avoided, by extending the size of the expansion plate towards the front of the main body, when the weight exceeds the proportion of the size to the weight of the hoisting machine, the mode that the load behind the hoisting machine is additionally increased is replaced, and the hoisting efficiency is improved. Therefore, manpower and material resources are reduced, use is convenient, and the practicability of the device is improved.
本发明涉及桥梁施工技术领域,且公开了一种高架桥钢混组合梁施工用吊装装置,包括主体和滑槽,滑槽开设在主体右侧,还包括扩展机构,扩展机构设置在滑槽内部,扩展机构包括有扩展板,扩展板滑动连接在滑槽内部,扩展板左侧固定连接有抵板,抵板远离扩展板的一侧固定连接有两个气缸,两个气缸以抵板为中心对称分布。本发明当伸缩架的尺寸伸的较长同时吊装的重量较大时避免导致该装置发生向前倒塌的现象,通过延伸扩展板向主体前方的尺寸,当遇到重量超过吊装机尺寸与重量的比例时,代替了外额外增加吊装机后方的负重的方式,从而降低了人力与物力,并且使用起来较方便,从而提高了该装置的实用性。
