For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] See also Figure 1The present invention provides a technical solution: a stepped lifting platform, comprising a base plate 1, a first lifting mechanism 2, a second lifting mechanism 4 and a third lifting mechanism 6 are arranged on the top of the base plate 1 along one lateral side, the top of the first lifting mechanism 2 is fixedly connected with the first lifting plate 3, the top of the second lifting mechanism 4 is fixedly connected with the second lifting plate 5, the top of the third lifting mechanism 6 is fixedly connected with the third lifting plate 7, a stretcher 11 is arranged on the top of the first lifting plate 3, the second lifting plate 5 and the third lifting plate 7, and a crawler is fixedly connected to one end of the bottom of the base plate 1; a fixing mechanism 9, the fixing mechanism 9 is used to fix the stretcher, and the fixing mechanism 9 is connected to the third lifting plate 3, the second lifting plate 5 and the first lifting plate 7; a buffer support assembly, the buffer support assembly is used to support the base plate 1, and the buffer support assembly is connected to the base plate 1.

[0030] The present invention improves the existing lifting platform. The existing lifting platform has only one lifting plate, while the present invention is provided with three lifting plates, namely the first lifting plate 3, the second lifting plate 5 and the third lifting plate 7. The three lifting plates are all lifted and lowered by a lifting mechanism. When in use, the lifting platform of the prior art is improved. Three lifting plates are sequentially arranged on the top of the bottom plate in the horizontal direction. When in use, the present invention is placed on the side of the rescue machine, and the three lifting plates are all raised to the highest point. Then the wounded are transferred out of the rescue machine and placed on the stretcher 11 of the first lifting plate 3. Then the first lifting plate 3 is lowered to the lowest point. The wounded and the stretcher 11 can be very conveniently transferred to the ambulance together. During the whole process, the transportation of the wounded is relatively simple, and the wounded will not be aggravated and the life and health of the transporting personnel will not be harmed.

[0031] During use, when there are multiple wounded persons in the rescue aircraft, another group of transfer personnel can retreat from the first lifting platform 3 to the second lifting platform 5, and then transfer the wounded persons by the same method as mentioned above, which can better transfer multiple wounded persons and will not cause the transfer to be complicated due to only one stretcher after transferring multiple wounded persons, thereby affecting the efficiency of transferring the wounded persons.

[0032] At the same time, the height of the rescue machine matches the height of the first lifting mechanism 3. At the same time, in order to better transport multiple wounded persons, there is a certain height difference between the heights of the first lifting mechanism 2 and the second lifting mechanism 4 and the third lifting mechanism 6, in order to facilitate the transportation of multiple wounded persons.

[0033] See also Figure 2The present invention provides a new embodiment, the fixing mechanism 9 includes a placing block 901 fixedly connected to the third lifting plate 7, the second lifting plate 5, and the other two ends of the top of the first lifting plate 3, a first semicircular groove 902 is opened through the top of one end of the placing block 901, and the two first semicircular grooves 902 are respectively used to place two rods of the stretcher 11, and a fixing block 12 is set at both ends of the top of the placing block 901, and a second semicircular groove 1201 is opened through the bottom of one end of the fixing block 12, and the rod of the stretcher 11 is set inside the second semicircular groove 1201.

[0034] Furthermore, the first connecting plates 903 are fixedly connected to both ends of the top of the front side of the placement block 901 , and the second connecting plate 1202 is fixedly connected to the bottom of the front side of the fixing block 12 , and the bottom of the second connecting plate 1202 is in contact with the top of the first connecting plate 903 .

[0035] Furthermore, a fixing opening 904 is formed through the top of the first connecting plate 903 , and a fixing rod 1203 is fixedly connected to the bottom of the second connecting plate 1202 corresponding to the fixing opening 904 , and the fixing rod 1203 is snap-fitted into the fixing opening 904 .

[0036] The stretcher 11 is fixed by a fixing mechanism, and the fixing mechanism can make it very convenient to remove the stretcher 11. After the wounded is placed on the stretcher 11, the stretcher 11 can be very easily removed, and the wounded can be better transported. Specifically, when in use, after the wounded is placed on the top of the stretcher 11, the transporter pulls up the two fixing blocks 12 on the top of the two placement blocks 901. After the fixing blocks 12 are pulled out, the transporter can very easily lift the stretcher 11 and the wounded. After the stretcher 11 is used up, the stretcher 17 is replaced in the first semicircular groove 902, and then the fixing block 12 is replaced above the placement block 901. Specifically, the fixing rod 1203 is inserted into the fixing port 904, so that the stretcher 11 is pressed by the fixing block 12, and the stretcher 11 is detachably installed, which is convenient for the use of the stretcher 11.

[0037] See also Figure 3 and Figure 4 The present invention provides a new embodiment, the buffer support assembly includes a configuration block 8 fixed to the other end of the bottom of the base plate 1, the two ends of both sides of the configuration block 8 are fixedly connected with electric telescopic rods 14, the two electric telescopic rods 14 on the same side are fixedly connected with a mounting plate 13, the bottom center of the mounting plate 13 is fixedly connected with a telescopic support frame 15, the bottom of the telescopic support frame 15 is fixedly connected with a buffer plate 16, the two ends of the bottom of the buffer plate 16 are fixedly connected with a fixed seat 17, a buffer rod 18 is slidably connected in the fixed seat 17, the bottom of the buffer rod 18 is fixedly connected with a first fixed block 20, a fixed rod 21 is fixedly connected in the first fixed block 20 through a damping shaft, and the other end of the fixed rod 21 is fixedly connected with a second fixed block 22 through a damping shaft.

[0038] Furthermore, a support plate 10 is arranged below the buffer plate 16, and a storage bin base 24 is fixedly connected to the top center of the support plate 10, and sliding guide rails 23 are fixedly connected to the centers of the two sides of the top of the support plate 10, and the other end of the sliding guide rail 23 is fixedly connected to the storage bin base 24. A sliding groove 27 is provided at the top of the sliding guide rail 23, and a slide plate 26 is slidably engaged in the sliding groove 27. The top of the slide plate 26 is connected to the second fixed block 22, and the bottom of the second fixed block 22 is in contact with the top of the sliding guide rail 23.

[0039] Furthermore, a placement bin 25 is fixedly connected to the top of the placement bin base 24 , and heavy objects are placed in the placement bin 25 .

[0040] Furthermore, a telescopic rod 28 is fixedly connected to the center of the outer end of the slide groove 27, and a shock-absorbing spring 19 is sleeved on the surface of the telescopic end of the telescopic rod 28. The two ends of the shock-absorbing spring 19 are respectively connected to the slide plate 26 and the fixed end of the telescopic rod 28.

[0041] Before use, start the electric telescopic rod 14. The start of the electric telescopic rod 14 will move the mounting plate 13 and the structure at its bottom to the side, which can better support the present application. Then start the telescopic support frame 15 to move the bottom of the support plate 10 to the top of the ground. During use, when the buffer plate 16 is acted upon by an external force, the fixing seat 17 will move downward along the buffer rod 18, thereby causing the fixing rod 21 to rotate appropriately. During the rotation of the fixing rod 21, the second fixing block 22 will move outward, thereby causing the slide plate 26 to move outward, thereby compressing the telescopic end of the telescopic rod 28, thereby compressing the shock-absorbing spring 19, converting the external force into the elastic force of the shock-absorbing spring 19, and buffering the external force through the shock-absorbing spring 19, making the support of the present invention more stable, and facilitating the transporter to perform simple treatment of the wounded at the lifting plate.

[0042] See also Figure 3 A storage bin base 24 is fixedly connected to the top center of the support plate 10, and a storage bin 25 is fixedly connected to the top of the storage bin base 24. Before use, appropriate weights are placed in the storage bin 25. By setting the weights, appropriate gravity is applied to the top of the buffer support assembly. Because gravity acts on the support plate 10, the support between the support plate 10 and the ground is more stable.

[0043] How it works: See Figure 5 Before use, the present invention is moved to the side of the rescue vehicle by the crawler, and appropriate weights can be placed on the placement bin 25 to better support the present invention.

[0044] The three groups of transport personnel all enter the first lifting platform 3, and then the other two groups appropriately retreat and enter the second lifting platform 5 and the third lifting platform 7 respectively, and then lift the first lifting mechanism 2, the second lifting mechanism 4, and the third lifting mechanism 6, and then transport the wounded from the rescue machine and place them on the stretcher 11. After the transport personnel properly treat the wounded, they pull out the fixing block 12, and then take out the wounded and the stretcher 11 together. After multiple wounded are rescued in the rescue machine, a wounded is placed from the rescue machine to the first lifting platform 3. After going up, the rescue aircraft appropriately lowers its height to be level with the height of the second lifting plate 5, and so on, so that multiple wounded can be better transported. There will not be a situation where the transport of multiple wounded is complicated due to only one stretcher, which in turn affects the efficiency of transporting the wounded. Then the first lifting mechanism 3, the second lifting mechanism 5, and the third lifting mechanism 9 are lowered. Finally, each group of transport personnel transports the wounded together with the stretcher 11 to the ground, and transports the wounded to the ambulance, so that the wounded are transported to the hospital for treatment.

[0045] It should be noted that the crawler, the first lifting mechanism 2, the second lifting mechanism 4, and the third lifting mechanism 6 in the present invention are all prior arts, and their specific internal structures and working principles will not be described in detail here.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
