The invention discloses self-lifting equipment for bridge maintenance. The equipment comprises a main body, a speed regulating mechanism, a rotating plate, a connecting shaft, an abutting block, a first rotating plate, a second rotating plate, a connecting belt, a first rotating shaft, a winding disc, a pull rope, a third rotating plate, a fourth rotating plate, a spring, a speed reducing mechanism, a driving motor, a worm, a worm wheel, a second rotating shaft, a first gear, a second gear, a third rotating shaft, a first bevel gear, a second bevel gear, a fourth rotating shaft, a pothook mechanism, and a lifting hook mechanism. The equipment has the beneficial effects that the driving motor is started to drive the worm to be engaged with the worm wheel to rotate, so that the pull rope inthe winding disc starts to be rolled up or released; when the speed needs to be increased, the rotating plates are rotated, the connecting belt on the first rotating shaft expands, and the connectingbelt on the second rotating shaft contracts, so that the pull rope rises and falls more quickly and workers can freely adjust the lifting speed conveniently according to specific conditions on site, so that unnecessary waiting time is avoided, and the working efficiency is improved.
本发明公开了一种桥梁检修用自升降设备,包括主体、调速机构、转盘、连接轴、抵块、第一转盘、第二转盘、连接带、第一转轴、收纳盘、拉绳、第三转盘、第四转盘、弹簧、减速机构、驱动电机、蜗杆、涡轮、第二转轴、第一齿轮、第二齿轮、第三转轴、第一斜齿轮、第二斜齿轮、第四转轴、挂钩机构和吊钩机构。本发明的有益效果是:启动驱动电机带动蜗杆啮合涡轮转动,使得收纳盘内的拉绳开始卷收或释放,当需要提升速度时,转动转盘,第一转轴上的连接带扩张,第二转轴上的连接带收缩,使得拉绳更加快速的实现升降,方便了工作人员根据现场的具体情况来自由调节升降速度,避免了不必要的等待时间,提高了工作效率。
