Auxiliary construction tool for longitudinal and transverse sliding of steel box girder

YANG XUEBIAO

The invention relates to the technical field of constructional engineering, and discloses a steel box girder longitudinal and transverse sliding auxiliary construction tool which comprises a switching mechanism, the switching mechanism comprises a hoisting motor, the output end of the hoisting motor is fixedly connected with a switching rotating disc, and a gyroscope positioning seat is fixedly arranged on the inner side of the switching rotating disc; an upper intermittent lifting mechanism and a lower intermittent lifting mechanism are arranged on the inner side of the switching mechanism, and each intermittent lifting mechanism comprises a front lifting motor and a rear lifting motor; through mutual cooperation of the hydraulic supporting mechanism, the intermittent lifting mechanism, the hydraulic rolling mechanism and the hydraulic pushing mechanism, sliding friction of the bottom side of the steel box girder can be changed into rolling friction while the steel box girder is lifted, and the hydraulic pushing mechanism can push the steel box girder to move in a hydraulic mode; damage to the steel box girder caused by sliding friction can be avoided, thrust can be provided for movement of the steel box girder, and energy consumption and the damage rate of the steel box girder are greatly reduced.

本发明涉及建筑工程技术领域，且公开了一种钢箱梁纵横向滑移辅助施工工具，包括切换机构，所述切换机构包括起重电机，所述起重电机输出端固定连接有切换转盘，所述切换转盘内侧固定设置有陀螺定位座，所述切换机构内侧设置有上下两个间歇抬升机构，所述间歇抬升机构包括前后两个起重电动机，通过液压支撑机构、间歇抬升机构、液压滚动机构和液压顶推机构的相互配合下能够在抬起钢箱梁的同时将钢箱梁底侧滑动摩擦改变为滚动摩擦，并且能够利用液压方式时液压顶推机构推动钢箱梁移动，既能够避免滑动摩擦给钢箱梁带来的损害，还能够为钢箱梁的移动提供推力，大幅降低能耗和钢箱梁的损坏率。
