[0030] Example:

[0031] based on Figures 1 to 5 As shown, this embodiment provides a stair transport structure based on pressure regulation and a method of use, which is characterized by including: a mounting frame 10, which is used to install rescue equipment; two sets of walking mechanisms 20, respectively installed on both sides of the mounting frame 10, for assisting in driving the mounting frame 10 to move; a speed control component 30, which is installed on the mounting frame 10 and is transmission-connected to the walking mechanism, and is used to actively adjust the travel speed of the walking mechanism; a pressure control component 40, which is installed on the mounting frame 10 and is electrically connected to the speed control component 30.

[0032] In this embodiment, if Figures 1 to 5 As shown, the walking mechanism consists of a crawler frame, crawler tracks, and a transmission system. The crawler tracks are located at the bottom of the mounting frame 10 and are in direct contact with the inclined surface of the ladder during ladder transportation, providing support and friction. The power of the motor is transmitted through a pair of cylindrical spur gears, and separately designed components are used to fix the transmission shaft to ensure smooth transmission of the two gears.

[0033] Furthermore, in some implementations of this embodiment, Figures 1 to 5 As shown, the pressure control component 40 includes: a pressure sensor 41, which is mounted on the mounting frame 10 and electrically connected to the speed control component 30, and is used to transmit the pressure signal to the speed control component 30; a transmission rod 42, which has a rotation angle, and one end of the transmission rod 42 is mounted on the mounting frame 10, and the transmission rod 42 abuts against the surface of the pressure sensor 41.

[0034] In this embodiment, if Figures 1 to 5 As shown, the motor speed is adaptively adjusted by the transmission rod 42 and the pressure sensor 41. When climbing stairs, as the speed and movement of the person behind increases, the force applied to the transmission rod 42 increases, and the motor speed increases; when descending stairs, the speed decreases or the force increases, the force applied to the transmission rod 42 increases, and the motor speed slows down. If the descent speed is too fast or the swing amplitude is large, the motor can be automatically braked by the angle or inertial sensor to reduce the risk of slipping.

[0035] Furthermore, in some implementations of this embodiment, Figures 1 to 5 As shown, two groups of pressure sensors 41 are provided, symmetrically arranged on the mounting frame 10 , two groups of corresponding transmission rods 42 are provided, and a connecting portion 43 is provided between the two groups of transmission rods 42 .

[0036] In this embodiment, if Figures 1 to 5 As shown, the two groups of transmission rods 42 are connected to the connecting portion 43, which makes it easier to transmit the two groups of transmission rods 42 and improves the accuracy of control.

[0037] Furthermore, in some implementations of this embodiment, Figures 1 to 5 As shown, the rotation angle is 0° to 15°

[0038] In this embodiment, if Figures 1 to 5 As shown,

[0039] Furthermore, in some implementations of this embodiment, Figures 1 to 5 As shown, the speed control component 30 includes: a control center 31, which is connected to the pressure sensor 41 through an electrical signal; a drive motor 32, and the control center 31 is used to control the rotation speed of the drive motor 32, and the drive motor 32 is transmission-connected to the walking mechanism.

[0040] In this embodiment, if Figures 1 to 5 As shown, the control center 31 is composed of a motor, a battery, an STM32 microcontroller, sensors and transmission components; the battery provides power for the entire system and is hot-swappable.

[0041] A method for using a transport structure based on the above device includes the following steps:

[0042] S1. Install the rescue equipment on the main body of the mounting frame 10;

[0043] S2. When the device is ascending the stairway, the rotation angle of the rotating rod is increased by adjusting the rotation angle, thereby controlling the walking mechanism to assist traction on the uphill slope;

[0044] S3. When the device is descending the staircase, the rotation angle of the rotating rod is adjusted to be smaller, thereby controlling the walking mechanism to provide stopping force for the downhill.

[0045] In summary, the transmission rod 42 is located at the rear of the entire device and is operated by the rear operator when the stairway is climbing. When the device is ascending through the stairway, the rear operator pushes the handrail hard, the pressure sensor 41 is squeezed and increased, and the signal is transmitted back to the control center 31. The control center 31 increases the speed of the drive motor 32, thereby increasing the climbing speed of the transport device; if the operator cannot ensure his own safety and stability, the squeezing of the pressure sensor 41 is reduced, and the climbing speed of the device is reduced; when the stairway is descending, when the rear operator can stably control the device, the squeezing of the pressure sensor 41 can be reduced. Increase the speed of the motor to speed up the descent of the device on the stairway. When the device descends too quickly, the operator needs to increase the force on the pressure sensor 41 to reduce its descent speed; when the pressure sensor 41 is not under force, the entire device stops moving. The entire operation process is more in line with the operating habits of personnel on the stairway, which is convenient for rear personnel to control. During the transportation process, the rear personnel are responsible for monitoring and adjusting the operating status of the drive track module so that the transportation device can move stably on the stairway. By controlling the walking mechanism to start, forward and reverse, the transportation device can go up and down the stairway, thereby improving the convenience of the device.

[0046] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. 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. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
