Hand-lift portable aerial operation platform

Abstract

The invention discloses a hand-lift portable aerial operation platform, which comprises a base, idler wheels, an operation platform, a support rack group and an elevating mechanism, wherein idler wheels are respectively arranged at four corners of the bottom of the base; the support rack group is composed of a bottom support rack, a middle support rack and a top support rack, which are vertically arranged in parallel and are arranged from outside to inside; the operation platform is fixedly arranged at the top of the support rack group; the elevating mechanism is composed of a jacking mechanism and a middle elevating mechanism; and the base is composed of two base sleeve pipe shafts, four lock sleeves, two base beams and four idler wheel brackets. According to the hand-lift portable aerial operation platform, the support rack group can be rapidly and synchronously elevated only by hand cranking without other power; the hand-lift portable aerial operation platform can be rapidly disassembled and assembled on the scene, and can be rapidly evacuated in emergency circumstances; and the hand-lift portable aerial operation platform has the advantages of being convenient to carry, light in weight, flexible and convenient, is a novel railway and common pavement operation platform, and is especially suitable for field operation in electric circuits of railways.

Description

technical field [0001] The invention relates to an aerial work platform, in particular to a hand-cranked lift-type portable aerial work platform that can work without electricity, and is especially suitable for the erection and maintenance of railway or subway lines. Background technique [0002] At present, the liftable aerial work platforms are all composed of an integrated base, a telescopic or cross-type support frame and a work platform. Rollers are installed at the bottom four corners of the base, and an electric motor or hydraulic cylinder or other power is installed on the base. For equipment, the support frame fixed on the base is composed of more than two layers of support frames stacked up and down, and a working platform is fixed on the top of the support frame. When working, the staff turns on the power, and realizes the up and down lift of the working platform through the electric motor or hydraulic cylinder or other power equipment. Because these power device...

AI Technical Summary

Problems solved by technology

Because these power devices are too bulky, they cannot be disassembled and assembled on site, so the use occasions are subject to great constraints and restrictions. In some occasions where power cannot be provided or the handling is not convenient, it cannot be used or cannot be conveniently and quickly Lifting and moving, affecting work efficiency

[0003] When the staff work in the field, especially in caves, the construction will occupy the rails or the road surface. In case of emergency, the aerial work platform is too heavy for the staff to disassemble and disassemble the aerial work platform in a short time. Only forcibly lift or push the aerial work platform out of the rail or road, otherwise it will cause unnecessary economic losses and casualties
