Description

Technical Field

[0001] The invention belongs to the technical field of stretcher transport devices, and in particular relates to an electric lifting stretcher transfer vehicle. Background Art

[0002] Stretchers are commonly used tools for transporting the wounded. At present, when transporting stretchers over long distances, trains are often used for centralized transportation. In the past, moving a stretcher to a train required two people to work together to lift the stretcher to the appropriate position and height in the carriage and then secure it. Usually, the stretcher is fixed to the seat in the train to stabilize the position of the stretcher and ensure the safety of the wounded. However, the operating space on the train is limited, and two people need to move left and right to operate, which is not only inconvenient to operate and consumes a lot of manpower, but is also prone to bumps and collisions, and the safety is worrying. Summary of the invention

[0003] In order to solve the above problems, the present invention 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] To achieve the above object, the technical solution of the present invention is as follows:

DETAILED DESCRIPTION

[0021] The technical solution provided by the present invention will be described in detail below in conjunction with specific embodiments. It should be understood that the following specific implementation methods 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 2As 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 the electrical equipment control box and be used for storage. The supporting platform is flat as a whole and is used to support the stretcher. Fixed protrusions 5 are arranged 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 arranged on the inner side of the fixed protrusion on one side, and a total of four fixing plates are arranged on the entire supporting platform. The fixing plate 6 is movably connected to the fixed protrusion 5 (through a rotating shaft or a rivet), so that it can rotate under the action of an 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 relatively 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. 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 to 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 3 As 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 both ends of the transverse support rods. 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 that is closer to the supporting platform is connected to the supporting platform 2 through a telescopic rod 12. The left support assembly and the right support assembly are respectively connected to the supporting platform through a telescopic rod 12. The two telescopic rods act 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 provided with a battery and a connection line for powering the electric telescopic hydraulic rod. The power supply, rising and falling buttons of the electric telescopic hydraulic rod are all arranged on the surface of the equipment control box. The door of the equipment control box is arranged on the side of the transfer vehicle body 1 for easy operation. The synchronous structure of the two telescopic rods and the button setting of the control box are all in the existing public technology. By operating the telescopic rod 12 to extend and retract, the lateral support frame and the longitudinal support frame in the support assemblies on both sides can change the connection angle, so that the transfer vehicle body 1 and the supporting platform 2 can be raised or lowered, and the electric lifting stretcher transfer vehicle can be widened or narrowed as a whole. There is also extra space in the transfer vehicle body 1 to accommodate other sundries, and a storage box arranged opposite to the control box can be set. 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 wheel should be a model that can be fixed by stepping on it, which is highly safe.

[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 components are vertically connected. 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 supporting components are opened at a large angle and are relatively stable, which is convenient for transporting 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. Preferably, a fixing plate is used 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 to 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 a level above the top of the seat by operating the telescopic rod to extend, such as Figure 2 As shown, the distance between the longitudinal support frames in the two support assemblies becomes narrower, and the electric lift stretcher transport vehicle can be moved between the seats more easily. If there are sufficient transport vehicles, the stretcher can be left on the transport vehicle and the injured can be transported together with the transport vehicle. If there are not sufficient transport vehicles, the stretcher can be removed and fixed on the seat, and the transport vehicle can be pushed off the train to transport other injured.

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