Self-walking column type overhead operation platform

Abstract

The present invention relates to aloft work machinery, and is especially mast type aloft work platform comprising chassis, mast with aloft work stage in the top, controller, hydraulic station and mast elevating hydraulic cylinder. The mast type aloft work platform features the dispersed walking wheels driven with hydraulic motor obtaining pressure medium from the hydraulic station and the steering wheel driven with the steering oil cylinder obtaining pressure medium from the hydraulic station. The mast type aloft work platform can move easily during aloft work and has small covered area, less aloft work ready time and auxiliary work time, and high work efficiency.

Description

technical field [0001] The invention relates to a high-altitude operation machine, in particular to a self-propelled mast type high-altitude operation platform capable of moving during work. Background technique [0002] Existing aerial work platforms for high-altitude operations, such as the four-mast aerial work platform described in the utility model patent with the notification number CN 2304648Y, include a chassis on which a motor, a hydraulic station, and a hydraulic control unit are arranged. , electrical control device, walking power device and working ladder, there are four anti-tilt outriggers and four screw rod leveling outriggers at the corners around the chassis. When in use, first move the aerial work platform to a working position, prop up the anti-tilt outriggers and screw leveling outriggers to the ground, and then expand the mast to lift the work platform to high altitude. [0003] The aerial work platform with this structure needs to prop the legs on the ...

AI Technical Summary

Problems solved by technology

[0004] 1. When working, the outriggers are extended to the ground, and the whole machine is fixed at a specific position to work, so that the whole machine cannot walk when it is in the working state (that is, the mast is in the unfolded state). If you want to change the working position, you must retract the whole machine In this way, there are problems such as long preparation time and auxiliary work time, and low work efficiency.

[0005] 2. Since the outriggers are extended to the ground during work, the floor area is relatively large, and it is easy to be disturbed by some factors during use, making it difficult to make the workbench close to the ideal working position. For example, it is difficult to make some workbenches work against the wall

[0006] 3. The chassis is light, which makes the center of gravity of the whole machine relatively high, and there are potential safety hazards that are easy to tilt or overturn
