Maintenance support frame for facilities on outer wall of overpass

Abstract

The invention belongs to the technical field of highway maintenance and construction, and particularly relates to a maintenance support frame for facilities on the outer wall of an overpass. The maintenance support frame comprises an aerial ladder part, a hanging mechanism and a traveling mechanism, wherein the aerial ladder part is provided with a platform for a maintainer to stand on; the hanging mechanism can form position-limiting cooperation with a guardrail of the overpass; the lower end of the hanging mechanism is connected to the aerial ladder part and used for hanging the aerial ladder part on the outside of the guardrail of the overpass; the traveling mechanism is mounted on the hanging mechanism and is opposite to the top surface of the guardrail of the overpass; and the traveling mechanism is used for driving the maintenance support frame to travel along the guardrail of the overpass. The maintenance support frame for the facilities on the outer wall of the overpass can notonly travel along the guardrail of the overpass, but also ingeniously arrange all driving mechanisms on the position that the maintainer can easily touch. Only one maintainer is needed for completinga series of operations such as maintenance, support frame traveling and the like and the maintainer does not need to repeatedly return to a bridge deck in the operation process so as to greatly improve the maintenance and construction efficiency of the overpass.

Description

technical field [0001] The invention belongs to the technical field of road maintenance and construction, and in particular relates to a support for maintenance of facilities on the outer wall of a viaduct. Background technique [0002] With the continuous improvement of people's living standards, the number of cars is also increasing, and the traditional ground transportation can no longer meet people's daily traffic needs. Therefore, in recent years, many large and medium-sized cities are vigorously developing the construction of viaduct roads, followed by Increasingly heavy viaduct maintenance work. One of the difficulties in the maintenance of viaducts lies in the maintenance of the external wall facilities 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, generally a specially customized aerial ladder is stuc...

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
