Description
Technical field
The present invention relates to mechanical field, specifically a kind of flexible chain saw barrier-breaking deliverance apparatus of apery formula.
Background technology
China is that an earthquake is frequently national, and for the skyscraper of reinforced concrete structure, majority is after it caves in
Concrete frame and shear wall structure.And after earthquake disaster occurs, whether rescue efficiency is successful to rescue action extremely to weigh
Will.Rescue actual with reference to recent domestic earthquake barrier-breaking, be traditionally used for the portable equipment of rescuing and barrier-breaking concrete structure
Mainly have：Expander, rock drill, toothless saw and chain saw etc..These current rescue modes are all by rescue team member's hand-held tool
Remove live barrier-breaking concrete wall, so since rescue team member easily fatigue, barrier-breaking rescue efficiency it is low and easily secondary cave in make
Into life danger.
In the prior art, there is also some robot type chain saw cutting equipments, such as application number US20170066155A1's
A kind of cutter device of utilization motor transmission driving chain saw of U.S. Patent Publication, is characterized in that the device of the cutting timber exists
The durability of chain saw is improved during cutting and the energy loss in cutting process is reduced.The cutting side of the timber device
Method, although the cutting of robot type is realized in timber cutting process, can be in eminence cutting lumbering, make artificial work
Intensity decreases, reduce danger coefficient, strengthen mechanical operation, but have a problem that simultaneously：The cutter device is only intended to
Efficiently lumbering, it is impossible to which concrete shear force wall is cut into square hole to succour trapped personnel.
In addition, the Chinese patent of application number 201520163122.2 discloses a kind of chain saw cut-off machine testing stand, its feature
It is a kind of testing stand for being used to carry out armored concrete chain saw cut-off machine concrete cutting.Chain saw cut-off machine testing stand can facilitate
Cutting performance experiment efficiently is carried out to armored concrete chain saw cut-off machine and matched diamond saw chain.Although the invention
Relatively simple for structure, cost is relatively low, and automaticity increases, and cutting accuracy also increases, and improves trial cut efficiency, but
Have the disadvantage that：1st, when cutting concrete, when running into the reinforcing bar or hard particles of the inside, cutting force becomes big suddenly, easily goes out
Existing machine shake, it is possible to scrapping cutting tool；2nd, because the device is the cutting test platform of chain saw, mobile coagulation is passed through
Soil block is cut, it is impossible to cut into square hole, automaticity is restricted, it is impossible to used in earthquake field.
