Description
The present invention is the divisional application of a kind of patent of invention " method of suing and labouring of the rescue aid of three hand folding bridge-types ", former
The applying date of application is on May 30th, 2016, and the application number of original application is 2016103648369, the innovation and creation name of original application
Title is " a kind of method of suing and labouring of the rescue aid of three hand folding bridge-types ".
Technical field
The present invention relates to a kind of method of suing and labouring of the rescue aid of three hand folding bridge-types, more particularly to one kind has telescopic rod
Hand-rail type jack top have three sections of foldable platforms automobile rescue energy load-bearing quickly support emergency management and rescue dress
It puts.
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
The method of suing and labouring of device, quickly support three sections of foldable platforms the purpose of the present invention is to provide a kind of hand-rail type rescue dress
It puts, which can be rescued by independent operation to realize self, manpower, financial resources and time be greatly saved, which passes through
Three sections of foldable platforms on jack support the wheel of vehicle, adjust the direction in length and breadth of three sections of foldable platforms to complete certainly
I succour, vehicle by three sections of foldable platforms can with longitudinal translation and transverse translation, realize safe operation, it is laborsaving, reach just
In the purpose of operation, practicability is big.
The present invention is achieved through the following technical solutions：A kind of side of suing and labouring of the rescue aid of three hand folding bridge-types
