The invention discloses pre-assembly equipment for a steel box girder jig frame, which comprises a fixed top plate, two hoisting cables are symmetrically arranged at the bottom of the fixed top plate, a clamp is fixed at the tail end of each hoisting cable, two mounting covers are symmetrically fixed at the bottom of the fixed top plate, and two limiting rollers are symmetrically arranged in each mounting cover. A limiting groove is formed in the outer side wall of each limiting roller, and two lubricating assemblies are symmetrically arranged in each mounting cover; when the steel box girder hoisting device is used, the limiting grooves in the two limiting rolling wheels just hold the corresponding hoisting cables, the shaking amplitude of the hoisting cables during downward releasing is reduced, and therefore the shaking amplitude of a middle transverse partition plate between the two clamps in the downward placing process is reduced, and the positioning difficulty between the middle transverse partition plate and a bottom plate of a steel box girder is reduced.

    本发明公开了一种钢箱梁胎架用预拼装设备,包括固定顶板,固定顶板的底部对称设置有两个吊装缆绳,每个吊装缆绳的末端均固定有夹具,固定顶板的底部对称固定有两个安装罩,每个安装罩内均对称设置有两个限位滚轮,每个限位滚轮的外侧壁上均开设有限位凹槽,每个安装罩内还对称设置有两个润滑组件;本发明在使用时,两个限位滚轮上的限位凹槽正好抱合对应的吊装缆绳,降低吊装缆绳向下释放时的抖动幅度,从而减少两个夹具之间的中间横隔板在向下放置过程中的抖动幅度,减少中间横隔板与钢箱梁的底板之间的定位难度。
