Ladder assembly of aerial work platform

Abstract

The ladder assembly of the aerial work platform comprises a large arm, a small arm is movably arranged at the upper end of the large arm through a rotating shaft, a first fixing block is fixedly arranged at the lower end of the outer side surface of the large arm, a first hydraulic cylinder is movably arranged in the first fixing block through a rotating shaft, and a second fixing block is fixedly arranged on one side of the lower end of the small arm. And the shaft end of a telescopic rod of the first hydraulic cylinder is movably connected with the second fixing block through a rotating shaft, an operation platform body is fixedly arranged at the end, away from the large arm, of the small arm, and an expansion mechanism is arranged between the operation platform body and the small arm. The working platform is good in use effect, the overall range of the working platform body can be automatically increased and expanded through the expansion mechanism when needed, construction workers can work conveniently, meanwhile, the working platform can be rapidly contracted and folded, and inconvenience caused by large occupied space during transportation can be prevented.

Description

technical field [0001] The invention relates to the technical field of aerial work platforms, in particular to a ladder frame of aerial work platforms. Background technique [0002] Aerial work platforms are mainly used for the load-bearing function of workers working at heights. However, when such aerial work platforms currently used are working, the space of the workers' work area at the upper end is generally fixed, lacking the function of space expansion, and cannot Expand a larger space for workers' activities when needed, and fold up for easy transportation when moving or transporting. The current aerial work platform lacks this function. Contents of the invention [0003] The object of the present invention is to provide a ladder frame of an aerial work platform to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a ladder frame of ...
