The invention discloses a craning trolley for a steel beam bridge-erecting machine. The craning trolley for the steel beam bridge-erecting machine comprises a cross beam, wherein a support rod is arranged at the bottom of the cross beam; a support table is arranged at the top of the cross beam; and first adjustment devices are installed at the two sides of an inner cavity of the support table separately. According to the craning trolley for the steel beam bridge-erecting machine, two first steel wire ropes are arranged on the surface of a fixed sleeve on the support rod, the two first steel wire ropes are adjusted through two first adjustment devices separately, and the relative heights of the two ends of the support rod can be adjusted as needed, so that a steel beam can be greatly erected; and meanwhile, during use of the craning trolley for the steel beam bridge-erecting machine, the support rod is capable of extending towards the two sides, and the length of the support rod is increased, so that steel beams with different dimensions are adapted; and moreover, a movable frame is arranged on the surface of a movable rod on the support rod, the movable frame is hoisted on the cross beam through a second steel wire rope, and when the movable rod extends outwards to increase the length, the movable frame slides along the surface of the movable rod, the movable frame keeps staticin situ, and the tightness of the second steel wire rope does not need to be repeatedly adjusted, so that the time and labor are saved.
本发明公开一种用于钢梁架桥机的起重小车,包括横梁,所述横梁的底部设置有支撑杆,横梁的顶部设置有支撑台,支撑台的内腔两侧均安装有第一调节装置。本发明通过在支撑杆上固定套筒表面设置有两个第一钢丝绳,两个第一钢丝绳分别通过两个第一调节装置进行调节,可以根据需求调节支撑杆两端的相对高度,能够很好的对钢梁进行架设;同时,本发明在使用时,支撑杆可以向两侧延伸,增加支撑杆的长度,从而适应不同尺寸的钢梁,并且在支撑杆上活动杆的表面设置有活动架,活动架通过第二钢丝绳吊于横梁上,在活动杆向外延伸增加长度时,活动架会沿着活动杆的表面滑动,活动架保持原位不动,无需重复调节第二钢丝绳的松紧,省时省力。
