A manned lifting platform for substation operation and maintenance

Abstract

A manned lifting platform for substation operation and maintenance, which belongs to the field of lifting platforms, includes a base, and vertically arranged shafts are installed on the front, rear, left, and right sides of the outer periphery of the base, and incomplete gears are fixedly installed on the lower ends of the shafts. Worm, the worm is rotated and installed on the base, the lower end of the worm is fixedly equipped with gears, the gears can mesh with the corresponding incomplete gears respectively, one side of the worm is meshed with a worm wheel, the inner periphery of the worm wheel is fixedly connected to the outer periphery of the nut, and the thread The female internal thread installs the screw rod, the inner side of the screw nut is connected to the outer end of the horizontal tube by bearing rotation, the inner end of the screw rod can only move inward and outward in the horizontal tube, and the horizontal tube is fixedly connected with the base. The invention has simple structure and ingenious conception, the supporting legs do not need to be retracted, and the supporting legs can automatically adjust the distance that the supporting legs protrude according to the height of the lifting platform, so that the supporting area can be increased with the 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.
