The invention relates to a suspension lifting device for bridge construction. The suspension lifting device comprises a lifting platform, two lifting devices, a driving motor, a first transmission belt and a supporting frame; the two lifting devices are distributed at the front side and the rear side of the lifting platform in a parallel center mode, and each lifting device comprises a transmission shaft and auxiliary boxes arranged at the two ends of the transmission shaft; a driven wheel is arranged on each transmission shaft, a hydraulic cylinder is arranged between the lifting platform and each auxiliary box, winding wheels and circular-truncated-cone-shaped driving energy storage wheels are fixed to the positions, inside the auxiliary boxes, of the transmission shafts, lifting ropes are wound around the winding wheels, and a safety lock disc and three energy storage shafts annularly distributed around the corresponding transmission shaft are arranged inside each auxiliary box; and a driven energy storage wheel and an energy release wheel are fixed to each energy storage shaft. On one hand, the rotating speed of the transmission shafts is doubly limited through the counter-acting force of lock rods and tightening energy storage elastic pieces, so that the safety protection effect is achieved; and on the other hand, energy stored when the lifting platform descends is utilized, so that the workload of the driving motor when the lifting platform ascends is reduced.

    本发明涉及一种用于桥梁施工的悬吊提升装置,包括升降平台、两个升降装置、驱动电机、第一传动带和支撑架,两个升降装置平心分布在升降平台的前后两侧,升降装置包括一个传动轴以及设置在传动轴两端的辅助箱,传动轴上设置有从动轮,升降平台与辅助箱之间设置有液压缸,辅助箱内部的传动轴部位固定有收卷轮和圆台形的主动蓄能轮,收卷轮上缠绕有升降绳,辅助箱内部设置一个安全锁盘和三个围绕传动轴环形分布的蓄能轴,蓄能轴上固定有从动蓄能轮和释能轮,一方面,利用锁杆和收紧蓄能弹片的反作用力对传动轴的转速进行双重限定,起到安全防护作用;另一方面利用升降平台下降时所蓄的能,减小升降平台上升时驱动电机的工作负担。
