a walking mechanism

Abstract

The invention belongs to the technical field of road maintenance and construction and particularly relates to a travelling mechanism. The travelling mechanism comprises a section of movable track anda sliding trolley which is in sliding fit with the movable track along the length of the movable track; a hanging mechanism is connected with the sliding trolley through a lifting mechanism; and a sliding trolley driving mechanism used for driving the sliding trolley to slide on the movable track is further disposed between the movable track and the sliding trolley and comprises a movable block, apulling rope, a first winding reel and a second winding reel, wherein the first winding reel and the winding reel are coaxially arranged. According to the travelling mechanism, the movable track is introduced on the basis of a traditional traveling type scaling ladder, the travelling resistance of the scaling ladder is greatly reduced, meanwhile the movable block mechanism is adopted to drive thescaling ladder to travel, less effort is needed during operation, the operation difficulty is lowered, and the maintaining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of road maintenance and construction, and in particular relates to a walking mechanism. 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 stuck on the viaduct guardrail, and then construction w...

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
