Curve steel box girder pushing equipment
The invention discloses curved steel box girder pushing equipment which comprises a box body, a moving block is arranged at the bottom of an inner cavity of the box body, upper sliding rails are arranged between the front side and the rear side of the inner wall of the box body, and a first lead screw pair used for driving the moving block to move longitudinally is slidably connected between the tops of the two upper sliding rails. Lower sliding rails are arranged between the left side and the right side of the inner wall of the box body, a second lead screw pair which is the same as the first lead screw pair in structure is arranged between the tops of the two lower sliding rails, an ejector block is arranged between the tops of the two jacking oil cylinders, a containing cavity is formed in the ejector block, and when balls in sliding blocks stretch out of the ejector block, the balls in the sliding blocks can be placed in the containing cavity. At the moment, the balls make contact with the steel box girder, and when the position of the movable block is corrected, the balls can roll at the bottom of the steel box girder, so that the moving resistance during correction is reduced, and damage to the steel box girder and the jacking oil cylinder caused by friction force is reduced.
本发明公开曲线钢箱梁顶推设备，包括箱体，所述箱体内腔的底部设置有移动块，所述箱体内壁的前、后两侧之间设置有上滑轨，两个所述上滑轨的顶部之间滑动连接有用于带动移动块纵向移动的第一丝杆副，所述箱体内壁的左、右两侧之间设置有下滑轨，两个所述下滑轨的顶部之间设置有与第一丝杆副结构相同的第二丝杆副，通过在两个顶升油缸的顶部之间设置顶块，并在顶块的内部开设放置腔，当滑块的内的滚珠伸出顶块的外部时，此时滚珠与钢箱梁相接触，此时在对移动块的位置进行纠偏时，滚珠能够在钢箱梁的底部进行滚动，从而减小纠偏时的移动阻力，减小摩擦力对钢箱梁以及顶升油缸带来的损害。
