The method for transferring the rescue personnel 300 to the plateau emergency ambulance by the field transferring emergency cot 100 provided by the invention is as shown in fig. 1, 2, 3, 4 and 9:

s1, lifting the front part of the field transportation emergency cot 100, pulling the lifting piece 110 to rotate anticlockwise by about 180 degrees, and then lowering the field transportation emergency cot 100 to the front wheel 5 to fall on the ground by the hand-held hook pull rod 114;

s2, placing the person 300 to be saved on the support cloth 10 towards the front longitudinal pipe 124, and fixing the person 300 to be saved by using the protective belt 20;

s3, the transferring personnel 400 hold the hook and pull piece 114 by hand to pull the field transferring emergency cot 100 up until the front wheel 5 leaves the ground, and then the transferring personnel 400 continue to pull the field transferring emergency cot 100 to the plateau emergency ambulance;

s4, when the tail of the plateau type ambulance is reached, the hook pull rod 114 is hung at a baffle protrusion 214 at the tail end of a carriage floor 210 of the plateau type ambulance, then a transfer person 400 walks to the rear end of the field transfer ambulance, the rear longitudinal pipe 123 is lifted by hand, the three-state change-over switch (the mark of 'rising', 'closing', 'falling' can be marked on the three-state change-over switch) is pressed again to start the rotation of the worm output head motor 9, so that the front end of the bedstead 120 ascends along the lifting piece 110, and meanwhile, the transfer person 400 synchronously lifts the rear end of the bedstead 120 to realize that the bedstead 120 is basically parallel to the ground, and when the front end of the bedstead 120 moves up to the end, the three-state change-over switch is adjusted to the closing state;

s5, the transfer personnel 400 pushes the rear longitudinal pipe 123 forwards until the field transfer emergency cot 100 is completely moved onto the carriage floor 210.

When the field transportation emergency cot 100 of the present invention is used to transport a person 300 to be rescued on a slippery, relatively soft ground, the slide plate 70 is turned over under the rear wheel 40 and then transported as described above.

Principle that the worm output head motor 9 drives the front end of the bed frame 120 to rise along the lifting member 110:

when the front vertical tube 124 is positioned at the lower end of the pull-up member 110, the string 60 is connected only between the winding portion 83 and the string fixing hole 115, and is not wound on the winding portion 83; when the worm output head motor 9 is started, the worm 91 rotates to drive the worm wheel 81 to rotate, and the winch shaft 8 rotates to wind the rope 60 around the winding part 83, so that the front end of the bed frame 120 is lifted to the upper end of the lifting member 110 along with the winding of the rope 60 around the winding part 83. When the transfer person 400 pushes the rear vertical pipe 123 forward after the bed frame 120 is lifted to the upper end of the lift member 110, the lift member 110 rotates clockwise with the lower end of the hook pull rod 114 as a fulcrum, and after the front wheel 5 falls on the car floor 210, the link 111 on the lift member 110 rotates to be close to the magnet under the bed frame 120 to be adsorbed and fixed.

When the front end of the bed frame 120 is required to be moved down to the lower end of the lifting member 110, the lower end of the lifting member 110 is pulled away from the magnet, and then the lifting member 110 is rotated anticlockwise until the lifting member 110 is basically perpendicular to the bed frame 120, and then the worm output head motor 9 is started to rotate reversely until the front end of the bed frame 120 is moved down to the lower end of the lifting member 110. The lift element 110 can then be folded clockwise under the frame 120.

Of course, a mechanism such as a tape retracting mechanism may be continuously provided at the string fixing hole 115, so that the string 60 is always in a tightened state, further improving the convenience of the operation of moving the front end of the bed frame 120 of the present invention downward to the lower end of the lifting member 110.

The method for transferring the field transportation emergency cot 100 loaded with the personnel to be saved 300 to the emergency table 211 in the emergency carriage 200 in a labor-saving manner is provided by the invention, and refer to fig. 1, 2, 3, 6, 7, 8 and 10:

s1, moving the field transportation emergency cot 100 to the convex column 2152 on the bed lifting piece 215 can hook the rear side of the hook rod 6;

s2, holding the tail end of the lifting rod 2153 to be lifted clockwise, at this time, the convex column 2152 pulls the rear side of the hook rod 6 and the lower surface of the bedstead 120 to lift the upper part of the field transportation emergency cot 100, and then continuously rotating the lifting rod 2153 until the clamping rod 1242 below the front longitudinal tube 124 falls on the emergency table 211;

s3, holding the rear vertical pipe 123 by hand, lifting the bed frame 120 up to be parallel to the upper surface of the emergency table 211, then pushing the rear vertical pipe 123 to the clamping rod 1242 forward to clamp the clamping groove 2111 on the emergency table 211, and finally screwing the hand screw 2 on the side surface of the clamping rod 1242 to fix the field transportation emergency bed 100 on the emergency table 211.

The above examples of the present invention are merely illustrative of the present invention and are not intended to limit the embodiments of the present invention. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. Not all embodiments are exhaustive. All obvious changes or modifications which come within the spirit of the invention are desired to be protected.
