[0040] Example:

[0041] based on Figures 1 to 4 As shown, this embodiment provides an innovative device for transporting injured persons, comprising: a walking assembly, a loading assembly, and an auxiliary assembly. The walking assembly is located on both sides of the loading assembly and is used to provide traction. The walking assembly includes: a traction winch 11, two sets of walking tracks 12, and a pressure sensor 13. The traction winch 11 is installed on the loading assembly and is used to provide traction and guide direction; the two sets of walking tracks 12 are located on both sides of the loading assembly; the pressure sensor 13 is in communication with the two sets of walking tracks 12 and is used to control the travel speed of the walking tracks 12 by actively applying pressure; the auxiliary assembly includes: a plurality of fixed clamps 31, a clamping ring 33, and a locking buckle 34. The plurality of fixed clamps 31 are installed on the loading assembly and are provided with a rotation groove 32; the clamping ring 33 is rotatably installed in the rotation groove 32 and is used to clamp a stretcher; the locking buckle 34 is installed on the fixed clamp 31 and is used to abut the clamping ring 33 to fix the clamping ring 33.

[0042] In this embodiment, if Figures 1 to 4 As shown, four stretcher fixing buckles are connected to the walking track 12 of the transport device through the base. The upper end of the stretcher fixing buckle is connected to the stretcher by fixing the stretcher side tube. For the 68-II type stretcher, the inner diameter of the fixing buckle is reasonably designed. The stretcher plane is fixed vertically and horizontally to prevent the stretcher from falling out. A semi-closed design is adopted to ensure that the stretcher can be smoothly connected and fixed when it is deformed while carrying the injured. At the same time, a mechanical structure is designed for locking to prevent the stretcher tube wall from falling out during transportation and causing personal injury. The fixing buckle is controlled by a torsion spring and is locked and unlocked by pressing.

[0043] The optimized design of the manufacturing process, materials and structure of the device makes the device miniaturized, lightweight and modular. The alloy components used in the device are made of high-strength lightweight materials such as magnesium alloy and aluminum alloy. At the same time, carbon fiber tubes are used to replace some alloy components to achieve lightweight equipment and reduce energy consumption. By comparing the weight with common equipment, the weight of the equipment is reduced by more than 20kg. The positions of various modules of the device are reasonably allocated, the device space is compressed, and the overall size of the device is reduced from 1650mm×500mm×800mm to 1015mm×500mm×197mm, and the weight is reduced from 70kg to 23kg, achieving miniaturization and lightweight of the device. At the same time, the buckles used to fix the stretcher are modular The design is adapted to the widely used 68-II stretcher. The fixing clips can be replaced as needed to adapt to new stretchers. The traction winch 11 ensures that the device runs smoothly when the track slips: a clutch mechanism is set to achieve separation and closure with the drive motor, and the coil spring structure is used to enable the rope of the traction winch 11 to be quickly recovered and reused. During the actual rescue process, there will be a large amount of water accumulated on the ladder, and the walking track 12 will slip, causing the device to fail to operate normally. The control system based on the traction winch 11 can serve as a backup safety system. When the device slips and falls due to an accident, the traction winch 11 can pull the entire device to prevent the device from slipping and causing harm to the injured and operators, thereby ensuring the stability and safety of the device.

[0044] Furthermore, in some implementations of this embodiment, Figures 1 to 4 As shown, the auxiliary assembly also includes: multiple support blocks 35, stop blocks 37, and omnidirectional wheels 38. The multiple support blocks 35 are mounted on the loading assembly and have slide slots 36; the stop blocks 37 are mounted on the support blocks 35; and the omnidirectional wheels 38 are rotatably mounted in the slide slots 36 to assist the device in reversing.

[0045] In this embodiment, if Figures 1 to 4 As shown, an auxiliary device composed of a series of omnidirectional wheels 38 components is used to achieve flat ground movement and platform steering. Compared with the use of a stretcher wheel set, the stretcher can be automatically locked when standing up and can also move laterally, which improves the convenience of using the device. The omnidirectional wheels 38 can move directly in any specified direction on a plane and can move forward or backward along the direction of rotation of the wheel hub like ordinary directional wheels. The ball structure arranged around the circumference of the wheel hub of the omnidirectional wheel 38 allows the omnidirectional wheels 38 to move laterally in a fixed installation mode. When the device is equipped with a stretcher and a wounded person for flat ground transfer operation, the omnidirectional wheels 38 automatically move to the frictionless side along the slide 36, and the operator can pull the device to transport the wounded person; when turning at a narrow corner in the warehouse or turning the platform, two operators can stand up the device. At this time, the omnidirectional wheels 38 are locked under the action of gravity to prevent slipping, facilitate steering operations, and improve the convenience of using the device.

[0046] Furthermore, in some implementations of this embodiment, Figures 1 to 4 As shown, the loading assembly includes: a mounting frame 21, a cover plate 22, and an extended push rod 23. The mounting frame 21 has a mounting cavity, with two sets of crawler tracks 12 located on either side of the mounting frame 21, and the traction winch 11 mounted on the mounting frame 21; the cover plate 22 is mounted on the mounting frame 21, and the fixed base 31 is fixedly mounted on the cover plate 22; the extended push rod 23 is fixedly mounted on the mounting frame 21, and the pressure sensor 13 is arranged to abut the extended push rod 23.

[0047] In this embodiment, if Figures 1 to 4 As shown, an electric control system is also provided in the installation cavity, and the electric control system consists of a motor, a battery, and an STM32 single-chip microcomputer; the battery provides power for the entire system and is hot-swappable; the motor speed is adaptively adjusted by extending the push rod 23 and the pressure sensor 13. During the process of climbing stairs, as the speed and movement of the rear personnel increase, the force applied to the extended push rod 23 increases, and the motor speed increases; during the process of descending stairs, when the speed slows down or the force increases, the force applied to the extended push rod 23 increases, and the motor speed slows down. When the descent speed is too fast or the swing amplitude is large, the motor can be controlled to brake automatically by controlling the angle or the inertial sensor to reduce the risk of slipping.

[0048] The operating extension push rod is located at the rear of the entire device and is operated by the rear operator during the ladder climbing process. During the ladder climbing process, if the rear operator can ensure their own safety and stability on the ladder, they can push the extension push rod with force, and the pressure sensor 13 will be squeezed and increased, sending a signal back to the control panel, which will increase the motor speed, thereby increasing the climbing speed of the transport device. If the operator cannot ensure their own safety and stability, the squeezing of the extension push rod will be reduced, and the climbing speed of the device will be reduced. When the ladder descends, if the rear operator can stably control the device, the squeezing of the extension push rod can be reduced, the motor speed can be increased, and the descent of the device on the ladder will be accelerated. When the device descends too quickly, the operator needs to increase the force on the extension push rod to reduce its descent speed. When the extension push rod is not under force, the entire device stops moving. The entire operation process conforms to the operating habits of the personnel on the ladder, and this design enables the rear operator to control it. During the transport process, the rear operator is responsible for monitoring and adjusting the operating status of the drive track module so that the transport device can move forward stably on the ladder. The purpose of carrying the device up and down the stairs is achieved by controlling the motor of the drive crawler module to start, rotate forward and reverse.

[0049] Furthermore, in some implementations of this embodiment, Figures 1 to 4As shown, there is an offset angle between the extension direction of the slide groove 36 and the distribution direction of the cover plate 22 , and the contact surface between the stop block 37 and the omnidirectional wheel 38 is perpendicular to the extension direction of the slide groove 36 .

[0050] In this embodiment, if Figures 1 to 4 As shown, after the omnidirectional wheel 38 module is installed, it can be dragged freely when moving on the flat ground, and automatically locked when standing up to a larger angle, realizing automatic switching between the locked and unlocked states.

[0051] This embodiment also provides a method of use, comprising the following steps:

[0052] S1. Fix the stretcher. Align the stretcher with the clamping ring 33 and lower it. Press the locking buckle 34 to fix the relative position between the stretcher tube wall and the fixed clamping seat 31.

[0053] S2. Transporting on flat ground: After the stretcher is connected to the transport device, the front person lifts and pulls the front of the stretcher with the help of the stretcher straps and the extended push rod, and the rear person can use the omnidirectional wheels 38 or the stretcher straps to transport and move the stretcher;

[0054] S3. Turning movement: The front operator lifts the front end of the transport device to form an angle, while the rear operator holds both sides of the stretcher to ensure the stability of the transport device. The stretcher and the device are erected, and the omnidirectional wheels 38 are driven to slide along the slide grooves 36 until they abut against the stop blocks 37. The two omnidirectional wheels 38 are locked and released by tilting the stretcher, thereby completing the turning and aligning the device with the corridor.

[0055] S4. Climb or go down the stairs.

[0056] Furthermore, in some implementations of this embodiment, Figures 1 to 4 As shown, S4 includes the following steps:

[0057] S41. On the ladder, the rear personnel pulls the extended push rod to control the motor and start the climbing operation. The front personnel pulls the front of the stretcher to control the forward direction.

[0058] S42. At the end of the ladder climbing, the rear personnel stop the motor, hold the tail of the device, and lift the transport device onto the platform with the front personnel;

[0059] S43. After the climb is completed, the two operators unlock the fixing buckles and lift the stretcher to continue transporting the injured.

[0060] Furthermore, in some implementations of this embodiment, Figures 1 to 4 As shown, S4 further includes the following steps:

[0061] S44, on the ladder, the rear personnel control the motor by pulling the extended push rod and start the descent operation;

[0062] S45. When the ladder is finally lowered, the rear personnel stop the motor, hold the upper part of the device, and use the stretcher wheels to support the transport device and evacuate the ladder with the rear personnel;

[0063] S46. After completing the descent, the two operators unfastened the securing belts and lifted the stretcher to continue transporting the injured.

[0064] In summary, an innovative casualty transport device and method of use is used. By using an adaptive electric control module, it conforms to the operating habits of personnel on the ladder; by using omnidirectional wheels 38, it can assist two personnel to realize the flat movement of the device and stretcher and the platform steering operation process; by using carbon fiber materials and magnesium alloy materials, the overall weight is light, the size is small, and the multi-module structural design has a high matching performance with the stretcher, which is more suitable for ship environmental conditions.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope of the present invention should be included within the scope of protection of the present invention.
