Description
The present invention is a kind of divisional application of patent of invention " rescue aid of three hand folding bridge-types ", the application of original application
Day is on May 30th, 2016, and the application number of original application is 2016103643651, and the invention and created name of original application is a kind of " hand
The rescue aid of three folding bridge-types shaken.
Technical field
The present invention relates to a kind of rescue aid of three hand folding bridge-types, more particularly to a kind of hand-rail types thousand for having telescopic rod
There is the emergency rescue device quickly supported of the energy load-bearing of the automobile rescue of three sections of foldable platforms on the top on jin top.
Background technology
In vehicle driving process, one of wheel can be encountered or two of which wheel falls into the accident of ditch, bank, even
Wheel uses the accident on road surface, since road surface He Gou, bank bottom drop are more than very heavy heights of roofs, in such case it is difficult to sue and labour.
In situation about helping without other people, above-mentioned thing occurs for the especially in the wild, situation of the independent self-driving of driver
Therefore driver is more difficult to save oneself.
Pinner block, sandy soil, plank or vehicle etc. is pushed currently for above-mentioned accident, below generally use wheel with manpower
Mode is rescued, and in rescue operations, due to lacking auxiliary tool, inconvenience of gathering materials on the spot, often time-consuming, there are wheels
The uncompacted situation of under-filler, during automobile self-rescue, safety guarantee is difficult, the effect of anticipation is often not achieved, at present
Neither one can complete the emergency rescue device that vehicle is saved oneself with field handled by itself.
Invention content
The present invention goal of the invention be:For overcome the prior art without have it is a kind of can load-bearing the emergency management and rescue quickly supported
Device, the purpose of the present invention is to provide a kind of quickly support three sections of foldable platforms deliverance apparatus of hand-rail type, the equipment
