Folding walking support

Abstract

The invention belongs to the technical field of highway maintenance and construction, and particularly relates to a folding walking support, which comprises a scaling ladder part, a hanging mechanismand a walking mechanism; the scaling ladder part is provided with a platform for the maintenance personnel to stand; the hanging mechanism can form a limit fit with the guardrail of an overpass. The lower end of the hanging mechanism is connected with the scaling ladder part for hanging the scaling ladder part on the outer side of the guardrail of the overpass; the scaling ladder part is rotatablyarranged along the vertical axis relative to the hanging mechanism. According to the invention, the scaling ladder part is arranged along the vertical axis relative to the hanging mechanism, so thatthe scaling ladder part can be folded to the same side of the trolley to facilitate storage and transportation, the weight of the scaling ladder part is carried by the cooperation of a T-shaped blockand a T-shaped groove. The scaling ladder part can be ensured to rotate and the integral bearing capacity of the scaling ladder part is improved.

Description

technical field [0001] The invention belongs to the technical field of highway maintenance and construction, and in particular relates to a foldable walking support. Background technique [0002] With the continuous improvement of people's living standards and the increasing number of cars, traditional ground transportation has been unable to meet people's daily traffic needs. Therefore, in recent years, many large and medium-sized cities have vigorously developed the construction of viaduct roads. The increasingly onerous maintenance of the viaduct. One of the difficulties in the maintenance of viaducts is the maintenance of the facilities on the outer side walls of the bridge deck, such as the maintenance of wall lamps, drainage pipes and other facilities, as well as the maintenance of bridge deck joints. In the prior art, when maintaining the above-mentioned facilities, a specially customized cloud ladder is generally first clamped on the viaduct guardrail, and then the ...

AI Technical Summary

Problems solved by technology

The defect of this construction method is that most of the aerial ladders in the prior art can only be relatively fixed with the guardrail of the viaduct, that is to say, the construction personnel need to return to the bridge deck every time they complete the maintenance of a facility, and after readjusting the position of the aerial ladder Going down to the ladder again for construction, this kind of work efficiency is extremely low

In addition, although there are some aerial ladders with walking wheels in the prior art, this kind of aerial ladder requires other construction workers to push and pull on the bridge deck to realize the walking action, and the coordination between the aerial ladder and the guardrail is poor, not only walking is laborious , and it is difficult to ensure that the ladder and the guardrail are reliably fixed during the maintenance and construction process
