The invention discloses a crane for subway construction, and belongs to the technical field of cranes, the crane comprises two lifting frames, the upper parts of the two lifting frames are horizontally and rotatably connected with sliding seats respectively, the two sliding seats are jointly connected with a guide rail in a front-back sliding manner, the guide rail is connected with a monorail crane in a sliding manner, and the two sliding seats are respectively provided with an upper walking mechanism matched with the guide rail; lower walking mechanisms are installed at the bottoms of the two lifting frames respectively. Through mutual cooperation of the lifting frames, the sliding seats, the upper walking mechanisms and the guide rails, the front-back distance between the two lifting frames can be shortened, and therefore the lifting device can adapt to the narrow construction environment and space; by overturning the lower walking mechanism, friction rolling between the track wheels and the subway track or friction rolling between the supporting wheels and the ground can be utilized, and then indirect driving of the speed reduction motor to the track wheels and the supporting wheels is utilized, so that track walking and road walking are achieved; and the hair brushes rotating along with the supporting wheels can clean attached crops on the upper surface of the subway track.

    本发明公开了一种地铁施工用起重机,属于起重机技术领域,包括两个托举架,两托举架上部分别水平转动连接有滑动座,两滑动座共同前后滑动连接有导轨,导轨滑动连接有单轨吊,两滑动座分别安装有与导轨配合的上行走机构,两托举架底部分别安装有下行走机构。本发明通过托举架、滑动座、上行走机构和导轨的相互配合,能够缩短两托举架之间的前后距离,从而能够适应较窄的施工环境和空间;通过对下行走机构进行翻转,能够利用轨道轮与地铁轨道摩擦滚动,或者利用支撑轮与地面进行摩擦滚动,然后再利用减速电机对轨道轮和支撑轮的间接带动,从而兼备轨道行走和路面行走,而跟随支撑轮转动的毛刷能够对地铁轨道上表面的附作物进行清理。
