Lifting platform for bridge construction
The invention discloses a lifting platform for bridge construction, and relates to the technical field of lifting platforms. Comprising a sliding rail and a lifting table, a cavity is formed in the lifting table, a braking assembly and a driven assembly are arranged in the cavity, the braking assembly comprises a fixing rod, the fixing rod is fixed to the inner wall of the cavity, and the fixing rod penetrates through a rack and is in sliding connection with the rack. When the lifting platform is used, the whole device breaks down, the lifting platform drops suddenly, the pulley rotates rapidly on the sliding rail, under the action of centrifugal force, the L-shaped striking rod rotates and opens with the position, hinged to the rotating wheel, of the L-shaped striking rod as the circle center, and the L-shaped striking rod abuts against the L-shaped driven rod to drive the gear to rotate; the rack drives the L-shaped connecting rod and the arc-shaped clamping plate to move towards the side close to the pulley, so that the pulley is clamped and cannot rotate, the friction force between the pulley and the sliding rail is increased, the descending speed of the lifting table is slowed down, and the personal safety of workers is further guaranteed.
本发明公开了一种桥梁施工用升降式平台，涉及升降式平台技术领域。包括滑轨和升降台，所述升降台的内部开设有空腔，所述空腔的内部设置有刹停组件和从动组件，所述刹停组件包括固定杆，所述固定杆固定在空腔的内壁上，所述固定杆贯穿齿条且与齿条滑动连接。当升降台在使用时，装置整体发生故障，造成升降台骤降，滑轮在滑轨上快速转动，在离心力的作用下，L型打击杆以和转轮铰接的位置为圆心转动张开，L型打击杆抵在L型从动杆上带动齿轮旋转，齿条带着L型连杆和弧形卡板向靠近滑轮的一侧移动，将滑轮卡住，使得滑轮不能旋转，进而增大与滑轨之间的摩擦力，减缓升降台下降的速度，进一步的保障工作人员的人身安全。
