Problems solved by technology

If the working time at the same working height is long or the construction personnel need to go up and down the platform many times, it is necessary to operate the platform surface multiple times, which prolongs the construction time and reduces the work efficiency

Embodiment Construction

[0013] Below by specific embodiment the present invention is described in further detail:

[0014] Referring to the accompanying drawings, the lift working ladder provided in this embodiment is a ground tool designed for aircraft production and assembly. In order to facilitate the overall movement of the working ladder on the working site, the lifting platform 1 and the working ladder leading to the lifting platform are fixed on the movable frame 8 at the same time. The lifting device 7 provides power for the lifting or falling of the lifting platform 1. There are three fixed steps. The steps are composed of pedals fixed on the mobile frame. Between the fixed steps 2 and the lifting platform 1 are three movable steps 3, and the movable steps 3 are composed of movable pedals 4 and step brackets 5. The step bracket 5 of the movable step is integrally linked with the lifting platform. During implementation, the step bracket can be welded into an integral structure with the liftin...

Abstract

The invention provides a lifting working ladder, a set of movable steps are added between fixed steps and a lifting platform, step supports of the movable steps are in linkage with the lifting platform in a fixed mode, movable footsteps of the movable steps are connected with sliding rails on the two sides in a sliding mode so that the working ladder is lifted to any height within the travel distance, and all the moveable steps can provide continuous stepping so that a constructor can conveniently step on and step down the working platform.

Description

technical field [0001] The invention relates to a general ground equipment, in particular to an elevating work ladder. Background technique [0002] The working ladder is widely used in various work sites, and its purpose is to provide construction personnel with an operating height, so that construction personnel can carry out construction on the working surface that cannot be reached by standing on the ground. Common working ladders are divided into fixed height working ladders and elevating working ladders. The station plane of the lift working ladder can be raised and lowered, has good versatility, and can be applied to the construction of working faces of different heights. At present, the common methods of using the working lift are as follows: when the platform of the working lift is lowered to the lowest position, the construction personnel climb onto the platform through fixed steps, and then the lifting device raises the platform and the construction personnel to ...
