The invention discloses a manned lifting platform for operation and maintenance of a transformer substation, and belongs to the field of lifting platforms. The platform comprises a base, wherein transverse shafts are rotatably arranged on the front, rear, left and right sides of the periphery of the base correspondingly, incomplete gears are fixedly arranged at the lower ends of the transverse shafts, worms are arranged on two sides of the incomplete gears and rotatably arranged on the base, gears are fixedly arranged at the lower ends of the worms, the gears can be meshed and matched with thecorresponding incomplete gears correspondingly, worm gears are arranged on one sides of the worms in a meshed and matched mode, the inner peripheries of the worm gears are fixedly connected with theouter peripheries of nuts, lead screws are arranged in the nuts in a threaded mode, the inner sides of the nuts are rotationally connected with the outer ends of transverse pipes through bearings, theinner ends of the lead screws can only move inwards and outwards in the transverse pipes, the transverse pipes are fixedly connected with the base. The lifting platform is simple in structure and ingenious in conception, supporting legs do not need to be folded and unfolded, the outward extending distance of the supporting legs can be automatically adjusted by the supporting legs according to therising height of the lifting platform, and therefore the supporting area can be increased along with rising of the lifting platform.
一种变电站运维用载人升降平台,属于升降平台领域,包括底座,底座外周的前后左右分别转动安装横轴,横轴的下端固定安装不完全齿轮,不完全齿轮的两侧设有蜗杆,蜗杆转动安装在底座上,蜗杆的下端固定安装齿轮,齿轮能够分别与对应的不完全齿轮啮合配合,蜗杆的一侧啮合配合设有蜗轮,蜗轮的内周固定连接丝母的外周,丝母内螺纹安装丝杆,丝母的内侧通过轴承转动连接横管的外端,丝杆的内端仅能够在横管内向内与向外移动,横管与底座固定连接。本发明结构简单,构思巧妙,支撑腿无需收放,并能够使支撑腿根据升降平台升高的高度自动调节支撑腿向外伸出的距离,从而使支撑面积能够随升降平台的升高而增加。
