[0002] At present, medical trains such as the China Health Express, India Health Express, and the surgical emergency train developed by the Third Military Medical University, which are based on ordinary train carriages, have been used in many aspects. Medical trains have the ability to transport across regions, over long distances, and in large quantities, but ordinary medical trains have many inherent disadvantages such as large vibration, poor air quality, small space, large noise, electromagnetic interference, and uncomfortable rides, which limit the scope of medical treatment of medical trains. High-speed EMU carriages designed with high-tech concepts and manufactured with new materials and processes have the advantages of large space, low noise, smooth operation, closed space, and electromagnetic shielding, and are a good platform for the development of future high-level medical trains.

[0003] Due to the small space inside the carriage, if the wounded and sick are all transported through the carriage door, it may lead to problems such as long transfer time and inconvenience in transfer.

[0004] Therefore, it is considered to transport some of the wounded directly to the beds in the carriage through the window, which can save the time of transporting the wounded. In order to achieve the transportation effect, it is necessary to design a back-hanging platform and cooperate with a multifunctional shovel stretcher to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a back-hanging platform for transporting patients from the window of a high-speed train, so as to solve the problems of long transport time and inconvenience caused by transporting patients through the door of a carriage.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a back-hanging platform for transporting patients from the window of a high-speed train, comprising a back-hanging structure, a load-bearing frame, a foot-operated hydraulic cylinder and a support; The back-hanging structure includes a horizontally arranged bottom platform, two upright posts fixed on one side of the bottom platform, and a connecting plate arranged between the two upright posts. Vertical slide grooves are symmetrically provided on the inner sides of the two upright posts. Hooks are provided on the tops of the upright posts. The bearing frame includes a bearing platform, a slider and a strut; the bearing platform is a horizontally arranged rectangular frame structure, one end of which is symmetrically provided with two sliders that are connected to the inner sliding grooves of the two columns, one end of the slider is provided with a roller, and the other end is a fork structure, which is connected to the strut through the strut rotating shaft, and the other end of the strut is fixed to the bearing platform through the strut mounting shaft; The pedal hydraulic cylinder is vertically arranged on the bottom platform, and the cylinder of the pedal hydraulic cylinder is connected with a supporting plate fixed on the bearing platform through a hydraulic rod connecting shaft; the support is arranged below the bottom platform.

[0007] Furthermore, the support is composed of a base plate and a screw rod vertically fixed on the base plate, and the screw rod is threadedly connected to the bottom platform; two supports are provided, which are symmetrically arranged on both sides below the bottom platform.

[0008] Furthermore, the two sliders are connected to the bearing platform via a rotating shaft.

[0009] Furthermore, a roller assembly is provided in the bearing frame, and the roller assembly is arranged on the bearing platform.

[0010] Furthermore, foldable guardrails are symmetrically provided on both sides of the supporting platform.

[0011] Furthermore, a rib plate is provided between the bottom platform and a connecting plate above the bottom platform.

[0012] The present invention has a simple structural design and is easy to use. The back-hanging structure, the load-bearing frame and the foot-operated hydraulic cylinder are combined to realize the lifting and lowering of the back-hanging structure. The support arranged at the bottom plays a supporting and stabilizing role to ensure that the back-hanging structure is in stable contact with the platform. The present invention can transfer the patient into the carriage through the window of the high-speed train, shorten the patient's transfer time to a certain extent, and improve the transfer efficiency.
