[0032] The alternating loading device includes a gantry 10, which is installed on the top of the mounting plate 5. A first fixed block 12 is fixedly connected to the middle of the inner top of the gantry 10. A first motor 11 is fixedly connected to both sides of the gantry 10. The output shaft of the first motor 11 is fixedly connected to a first shaft rod 13. The first shaft rod 13 is located inside the gantry 10, and the first fixed block 12 is movably connected between the two first shaft rods 13 through a bearing.

The infrared transmitter 19 and the infrared receiver 20 are electrically connected to the first sub-controller 26 respectively. The infrared transmitter 19 transmits infrared rays which are received by the infrared receiver 20. If materials are placed on the storage basket 16, the infrared receiver 20 cannot receive the infrared rays emitted by the infrared transmitter 19, which means that materials are placed on the storage basket 16.

The flange 18 is located directly below the limiting strip 8. A pressure sensor 9 is embedded at the bottom of the limiting strip 8. When the storage basket 16 moves up through the first opening 7 and the bottom of the inner side of the storage basket 16 is at the same height as the upper surface of the mounting plate 5, the flange 18 is located at the bottom of the limiting strip 8 and presses on the pressure sensor 9 at the bottom of the limiting strip 8. At this time, it means that the storage basket 16 has moved up to the specified position.

[0036] A second sub-controller 37 is fixedly connected to the top of the gantry 10, and the first motor 11 and the pressure sensor 9 are electrically connected to the second sub-controller 37 respectively.

[0039] The bottom of the traction rope 14 is split into two ends, and a hook 15 is fixedly connected to each of the two ends of the bottom of the traction rope 14. Two hook holes 17 are respectively provided on the top of both sides of the storage basket 16. The hook 15 passes through the hook hole 17. The traction rope 14 is connected to the storage basket 16 through the hook 15 and the hook hole 17, so that the storage basket 16 is convenient to disassemble for storage, replacement or maintenance.

[0040] A master controller 28 is also installed on the side of the scissor lift 1. The master controller 28 is wirelessly connected to the first sub-controller 26 and the second sub-controller 37 respectively. At the same time, the operation of the scissor lift 1 and the belt conveyor 27 can also be controlled by the master controller 28.

[0041] Embodiment 2, on the basis of embodiment 1, a support mechanism 29 is respectively installed at the four corners of the bottom of the scissor-type lifting platform 1, and the support mechanism 29 includes a connecting sleeve 30, and the connecting sleeve 30 is fixedly connected to the bottom side of the scissor-type lifting platform 1, and a plug block 31 is inserted on one side of the connecting sleeve 30, and a threaded rod 34 is connected through the plug block 31, and the plug block 31 and the threaded rod 34 are threadedly connected, and one end of the threaded rod 34 is movably connected to a top block 35 through a bearing, and the other end of the threaded rod 34 is fixedly connected to a rotating wheel 36, and a pin 33 is inserted at the top of the connecting sleeve 30, and two vertically distributed pin holes 32 are provided on the outer surface of the plug block 31, and the pin 33 passes through one of the pin holes 32. The support mechanism 29 can make the scissor-type lifting platform 1 When used on an uneven ground, it can also quickly adjust the height of the four corners of the scissor-type lifting platform 1 to ensure that the scissor-type lifting platform 1 can adapt to different terrains to maintain a stable state of operation, and has a wider adaptability.

[0042] Working principle:

[0043] When supplying materials to the medical train, the scissor lift 1 can be moved to the side of the window of the medical train. If the ground is uneven, the height of the four corners of the scissor lift 1 can be adjusted through the support mechanisms 29 at the four corners of the scissor lift 1, so that the scissor lift 1 can be used in a balanced manner. When using the support mechanism 29, it is necessary to first pull out the latch 33 and then pull out the plug block 31 from the connecting sleeve 30 and then reinsert it into the connecting sleeve 30 after rotating it ninety degrees. Then, the latch 33 is inserted into the connecting sleeve 30 again so that the plug block 31 is fixed. At this time, the threaded rod 34 is adjusted from a horizontal state to a vertical state, and then the threaded rod 34 is rotated to push the top block 35 against the ground to adjust the height of the four corners of the scissor lift 1.

[0044] Then, the top plate 2 is raised by the scissor lift 1 so that the fixed plate 3 can be at the same height as the window of the sanitary train. When transporting materials, the materials are placed in one of the storage baskets 16. When the infrared receiver 20 cannot receive the infrared rays emitted by the infrared transmitter 19, the first sub-controller 26 will determine that there are materials in the storage basket 16, and the first sub-controller 26 will feed back the information to the main controller 28. Then the main controller 28 will send a signal to the second sub-controller 37, and the second sub-controller 37 will control the first motor 11 to start, and the output shaft of the first motor 11 will drive the first shaft 13 to rotate, and the first shaft 13 will reel the traction rope 14 on the first shaft 13, thereby pulling the storage basket 16 connected below the traction rope 14 upward until the storage basket 16 passes through the first opening 7 and the flange on the side of the storage basket 16 18 contacts the bottom of the limit strip 8, at this time, the pressure sensor 9 detects a pressure signal, and the second sub-controller 37 determines that the position of the storage basket 16 has risen to the specified position, and the second sub-controller 37 feeds back the signal to the main controller 28, and then the main controller 28 sends a signal value to the first sub-controller 26, and the first sub-controller 26 controls the second motor 22 to start, and the output shaft of the second motor 22 drives the second shaft rod 23 to rotate, and the second shaft rod 23 rotates to drive the friction wheel 24 to rotate, and the friction wheel 24 rotates to frictionally push the materials on the storage basket 16 to move quickly above the fixed plate 3 until it moves to the belt conveyor 27 on the fixed plate 3, and then it is transported to the window of the sanitary train through the belt conveyor 27 and carried into the train by personnel, and the two storage baskets 16 transport materials alternately up and down.
