Description
The present invention is the divisional application of the patent of invention equipment of rescue " a kind of fluid pressure type cross slide ", the application of original application
Day is on May 30th, 2016, and the application number of original application is 2016103643543, and the invention and created name of original application is a kind of " liquid
The equipment of pressure type cross slide rescue ".
Technical field
The present invention relates to a kind of fluid pressure type cross slide rescue aid, more particularly to a kind of hydraulic jack for having telescopic rod
Top have cross slide automobile rescue energy load-bearing the emergency and rescue equipment quickly supported.
Background technology
In vehicle driving process, one of wheel can be run into 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.
Such as：Granted patent " turns jack in vehicular rescue original place "（CN204588591U）There are above-mentioned technological deficiency.When road surface and
Ditch, bank bottom drop are more than very heavy heights of roofs, cause support platform and wheel to contact, it is impossible to normal use.If in " car
Rescue original place turn jack " bottom or top pinner block, not only rescue speed it is slow, be also absolutely unsafe.
Especially in the wild, the situation of the independent self-driving of driver, in situation about helping without other people, occurs above-mentioned thing
Therefore driver is more difficult to save oneself.
Pinner block, sandy soil, plank or vehicle etc. is promoted 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 wheel
The uncompacted situation of under-filler, during automobile self-rescue, safety guarantee is difficult, does not often reach the effect of anticipation, at present
Neither one can complete the emergency and rescue equipment that vehicle is saved oneself with field handled by itself.
The content of the invention
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
