Abstract

The invention relates to an aerial working device. The double-pole climbing aerial working platform comprises two sets of vertical tower assemblies and platform assemblies, wherein two sets of vertical tower assemblies are respectively composed of a top cap and a plurality of standard knots with frame structure; standard knots are in demountable fixed connection, and the standard knots, a connection frame and the top cap are also in demountable fixed connection; one side of the connection frame and one side of the standard knot are respectively provided with racks which are mutually connectedto form a tooth-shaped rail; the platform assembly is fixedly provided with an installation rack; the vertical tower passes through the installation rack which is provided with a roller; the roller sticks to the standard know in a rolling mode; the installation rack is also fixedly provided with a fixed plate; a motor and an anti-dropping safety device are both fixed on the fixed plate; the motoris connected with a drive gear; and the drive gear and the anti-dropping gear of the anti-dropping safety device are respectively meshed with the rack. The invention enlarges the range of the workingtable surface, can add the standard knots without limitation and has the advantages of wider operation range, high lifting height and reliable stability and safety.

Description

technical field [0001] The invention relates to a high-altitude operation device. Background technique [0002] Existing aerial work platforms, such as scissor lift work platforms, mast lift work platforms and telescopic lift work platforms, are generally used for the installation and maintenance of street lights or the handling of high-altitude goods, as well as other heights that are not too high. Aerial work. They generally all have the shortcomings of insufficient lifting height and a small range of worktables. In addition, existing scaffolding needs to be erected during the construction of building walls, which is time-consuming to construct and dismantle, and is not safe enough. Also there is not one that can work in a large area, and the high-altitude operation device with a high lifting height has been publicly reported. [0003] The applicant applied for an invention patent with the patent application number: 200910097374.9 on April 13, 2009. This patent disclos...
