[0002] Stretchers are a common tool for transporting the injured. Currently, long-distance stretcher transport often involves centralized transport on trains. Previously, moving a stretcher onto a train required two people to lift it to the appropriate position and height within the carriage before securing it. Typically, the stretcher is securely connected to a seat on the train to maintain its stability and protect the patient. However, limited operating space on trains requires two people to maneuver left and right, making this operation inconvenient and labor-intensive, as well as prone to collisions and unsafe conditions. Utility Model Content

[0003] In order to solve the above problems, the utility model discloses an electric lifting stretcher transfer vehicle, which adopts a unique structural design and cooperates with motor operation to electrically lift the height of the transfer vehicle and can adapt to the narrow space on the train.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the present utility model is as follows:

[0005] An electric lifting stretcher transfer vehicle comprises a transfer vehicle body, a supporting platform fixed on the top of the transfer vehicle body, and a left support assembly and a right support assembly respectively connected to both sides of the transfer vehicle body, the support assemblies on both sides respectively comprise two transverse support frames and a longitudinal support frame, the inner sides of the two transverse support frames are respectively connected to the transfer vehicle body through rotating shafts, and the outer sides of the two transverse support frames are respectively connected to the longitudinal support frames through rotating shafts, the left support assembly and the right support assembly are respectively connected to the supporting platform through a telescopic rod, one end of the telescopic rod is connected to the longitudinal support frame, and the other end is connected to the supporting platform, and universal wheels are respectively provided at the bottom of the left support assembly and the right support assembly.

DETAILED DESCRIPTION

[0021] The technical solutions provided by the present invention will be described in detail below in conjunction with specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0022] like Figure 1 、 Figure 2 As shown, the electric lifting stretcher transfer vehicle provided by the present invention includes a transfer vehicle body 1, a supporting platform 2, and a left support assembly 3 and a right support assembly 4 respectively arranged on both sides of the transfer vehicle body. The transfer vehicle body is in the shape of a rectangular parallelepiped and is located in the center of the transfer vehicle. It is used to connect various components, accommodate electrical equipment control boxes and be used as storage. The supporting platform is flat as a whole and is used to support the stretcher. Fixed protrusions 5 are provided on both sides thereof. The fixed protrusions protrude a certain height from the supporting platform, and the distance between the two fixed protrusions is adapted to the width of the stretcher. Two fixing plates 6 are provided on the inner side of the fixed protrusion on one side, and a total of 4 fixing plates are provided on the entire supporting platform. The fixing plate 6 is movably connected to the fixed protrusion 5 (through a rotating shaft or rivets), so that it can rotate under the action of external force. There is a certain gap between the fixing plate and the fixed protrusion, which can clamp the side edge of the stretcher. The end area of ​​the fixing plate is large, which can play a good fixing role. The left support assembly 3 and the right support assembly 4 are symmetrically distributed and have the same structure. Figure 1 The left side support assembly is used as an example for explanation. The left side support assembly includes two transverse support frames 7 and a longitudinal support frame 8. The four corners of the transverse support frame are connected with a rotating shaft 9. The inner side of the transverse support frame is connected to the main body of the transfer vehicle through two rotating shafts, and the outer side is connected to the longitudinal support frame through two rotating shafts. The two transverse support frames are arranged in parallel at the top and bottom. Figure 3As shown, more specifically, each transverse support frame includes two transverse support rods 10 and a longitudinal support rod 11 fixed between the two transverse support rods, and a rotating shaft 9 is connected to each end of the transverse support rod. The longitudinal support frame includes two longitudinal support rods 11 and a transverse support rod 10 fixed between the two longitudinal support rods. The higher transverse support rod in the longitudinal support frame, which is closer to the supporting platform, is connected to the supporting platform 2 via a telescopic rod 12. The left support assembly and the right support assembly are each connected to the supporting platform via a telescopic rod 12. The two telescopic rods operate synchronously, and the telescopic rods use electric telescopic hydraulic rods. An equipment control box 14 is provided in the transfer vehicle body 1, which is equipped with batteries and connection lines for powering the electric telescopic hydraulic rods. The power supply, up and down buttons of the electric telescopic hydraulic rods are all set on the surface of the equipment control box. The equipment control box door is set on the side of the transfer vehicle body 1 for easy operation. The synchronization structure of the two telescopic rods and the button settings of the control box are all part of the existing public technology. By operating the telescopic rod 12 to extend or retract, the connection angles of the lateral support frames and the longitudinal support frames in the support assemblies on both sides can be changed, thereby causing the transfer vehicle body 1 and the supporting platform 2 to rise or fall, and the electric lift stretcher transfer vehicle as a whole to be widened or narrowed. There is also extra space in the transfer vehicle body 1 to accommodate other sundries, and a storage box can be set opposite to the control box. Two universal wheels are connected to the bottom of the left support assembly, and the two universal wheels are respectively fixed to the bottom of the two longitudinal support rods of the longitudinal support frame. Similarly, two universal wheels 13 are connected to the bottom of the right support assembly. The universal wheels should preferably be of a type that can be fixed by stepping on, which is safer.

[0023] As a further improvement, the supporting platform 2 is connected to an infusion stand to facilitate infusion of the wounded during transportation.

[0024] When using the electric lifting stretcher transport vehicle provided by the present invention, the supporting platform 2 is set at a suitable height by operating the telescopic rod, usually Figure 1 The state shown is that the transverse support frame and the longitudinal support frame in the two support assemblies are connected vertically. At this time, the telescopic rod is shortened to the shortest, and the supporting platform 2 is at a lower position, which makes it convenient to lift the stretcher onto the supporting platform and fix it. The two support assemblies are opened at a large angle and are relatively stable, which makes it convenient to transport the wounded at stations and platforms. When the stretcher is set on the supporting platform, it is just stuck between the two fixed protrusions of the platform. It is preferred to use a fixing plate to clamp the edge of the stretcher. At the same time, the wounded on the stretcher should be further fixed by a fixing belt for protection. When the electric lifting stretcher transfer vehicle is transported onto the train, due to the narrow passage and the low height of the stretcher, it is easy to hit the train seat during transportation. At this time, the supporting platform 2 should be raised to above the top of the seat by operating the telescopic rod to extend, as shown in FIG. Figure 2As shown, the distance between the longitudinal support frames of the two support assemblies is narrowed, allowing the electrically operated stretcher transport cart to more easily fit between the seats. If transport carts are available, the stretcher can be left on and transported together with the transport cart. If transport carts are insufficient, the stretcher can be removed and secured to the seats, and the transport cart can be pushed off the train to transport other patients.

[0025] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, they can make several improvements and modifications without departing from the principles of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
