Abstract

The invention provides a ladder pedal mechanism and engineering machinery. The ladder pedal mechanism is applied to a chassis of a car body of the engineering machinery, and comprises a ladder frame, fixed pedals and a folding pedal, wherein the ladder frame extends downwards from the chassis; the fixed pedals are arranged on the ladder frame; the folding pedal is arranged on the bottommost fixed pedal of the ladder frame, and the folding pedal can be unfolded downwards and folded upwards. The ladder pedal mechanism disclosed by the invention has a folding function, i.e., the ladder pedal mechanism can be unfolded downwards as required, so that the distance between a ladder and the ground is shortened, thereby facilitating that workers get on a car through the ladder, and the ladder pedal mechanism can be folded upwards, so that the original safe distance between the ladder and the ground is kept, thereby avoiding that the ladder is damaged because of knocking against the ground or other objects.

Description

technical field [0001] The invention relates to the field of building construction equipment, more specifically, to a ladder pedal mechanism and a construction machine. Background technique [0002] In the prior art, vehicle personnel generally go up and down construction machinery such as pump trucks and cranes through fixed ladders or pedals. The ladders or pedals of the above construction machinery cannot be contracted, and are fixed on the outside of the chassis of the vehicle body by welding or bolting. In order to prevent the ladder from being damaged due to collision with the ground or other objects during vehicle assembly, the ladder should be installed as close as possible to the top, and the safe distance between the bottom end of the ladder and the ground is about 0.5m. When the hydraulic outriggers of the vehicle extend downward to support and fix the chassis of the vehicle body, the height of the chassis of the vehicle will rise, and the distance between the ped...
