Manned lifting platform for operation and maintenance of transformer substation

Abstract

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.

Description

technical field [0001] The invention belongs to the field of lifting platforms, in particular to a manned lifting platform for substation operation and maintenance. Background technique [0002] Manned lifting platforms are widely used in mid-to-high-altitude operations, especially in the operation and maintenance of substations. Lifting platforms are often used, but the existing lifting platforms are cumbersome to use and operate. The supporting legs need to be fully opened manually, and the opening distance of the supporting legs cannot be adjusted according to the lift Adjust the height (the higher the lifting platform rises, the longer the supporting legs extend outward, thereby increasing the supporting area), and manually retract the supporting legs after use, which brings a lot of inconvenience to the use of the lifting platform and cannot meet the actual needs , so we invented a manned lifting platform for substation operation and maintenance.
