Description
Technical field
The present invention relates to a kind of ladder, specifically a kind of integral multifunctional ladder used for field medicine belongs to medical
Vehicle arts field.
Background technique
For field medical team during execution task, personnel diagnose vehicle, field operation vehicle or transport vehicle in upper and lower field X-ray
It is needed when compartment afterwards using ladder, there are mainly two types of the ladders that army allots at present: one is the "-" type pedal ladder of fixed shape,
Another kind is folding pedal ladder."-" type pedal ladder sound construction, it is easy to operate, but its function is more single, and volume is big,
Occupied space is more when storage, and while encountering the uneven road surface in field is not adjustable level, influences the flat of personnel's ladder up and down
Weighing apparatus property.Folding pedal ladder is in a plane when collapsing substantially, saves parking space, but inconvenient when its expansion and gathering,
It is easy to happen the non-combat casualty accident that operator's finger is crushed by ladder, and its function is more single.Furthermore both ladders
Son all lacks protection handrail, when the handicapped sick and wounded walk on both ladders, need it is meticulous, to prevent from ladder
It is fallen on son, causes secondary injury.
In addition, equipment of field medical team when outgoing can simplify as far as possible, generally since field medicine requires mobility strong
It is not equipped with auxiliary handling instrument individually, when medical material is carried transport vehicle up and down, pickaback hand is lifted using more people substantially at present
Traditional approach, it is not only laborious but also time-consuming, when such as encountering bulky, overweight goods and materials, be easy to happen goods and materials and slide and injure people's by a crashing object
Accident.
Thus, it is therefore desirable to be able to develop it is a kind of used for field medicine integral multifunctional ladder, it is not only easy to carry,
Expansion and gathering rapidly, and can be applicable in various complex landform environment, take action, can also be used to convenient for medical staff and the sick and wounded
