[0046] It should be noted that the lower frame 1 is not only used to install the electric cylinder, but also used to install the controller, gyro sensor, camera device, motor, and battery pack. The camera device adopts but is not limited to the existing monocular camera. The above motor, electric cylinder, gyro sensor, and monocular camera are all electrically connected to the controller. When unmanned, the gyro sensor collects the posture information of the transport vehicle and transmits the information to the controller. The monocular camera collects the image information of the position of the transport vehicle and transmits the image information to the controller. The controller recognizes and processes the collected posture information and image information of the transport vehicle, combines the algorithms such as path planning and intelligent obstacle avoidance, realizes the functions such as path planning and intelligent obstacle avoidance, the motor drives the wheel 4 to rotate, and the battery pack supplies power to the controller, gyro sensor, camera device, motor, and electric cylinder. The above devices and algorithms can all be realized by using existing technologies, and the specific connection relationship and implementation scheme are not repeated here.

[0047] Working process:

[0048] When the camera and gyro sensor of the transport vehicle find that the transport vehicle is traveling in a well with a large slope, the controller controls the output shaft of the electric cylinder to extend, and the wheel 4 of the upper frame 3 presses against the upper end surface of the well, and the compression spring 7 is compressed. The compression spring 7 gives the upper frame 3 and the lower frame 1 opposite elastic forces. A pressure sensor is provided between the output shaft of the electric cylinder and the moving platform 2. When the pressure sensor reading reaches a specified value, the electric cylinder stops moving, so that the wheels 4 of the upper frame 3 and the lower frame 1 press against the lower end surface and the upper end surface of the well, respectively, increasing the friction between the wheels 4 and the well wall, so that the transport vehicle can travel in the well with a large slope. ( Fig.18 As shown, the transport is carried out in a vertical shaft); a compression spring 2 403 is provided between the contact block 402 and the rotation. When the surface of the shaft wall is uneven and there are protrusions, the compression spring 2 403 is compressed to offset the influence of the height of the protrusions, thereby ensuring sufficient contact between the other wheels 4 and the shaft wall, and transporting the items to be transported to the designated location.

[0049] When the transport vehicle needs to travel in a pipe with a smooth inner wall, a suction cup 5 is installed on the contact block 402. When the suction cup 5 is subjected to the pressing force of the wheel 4, the suction cup 5 is deformed and the gas inside the suction cup 5 is discharged. As the wheel 4 moves forward, the suction cup 5 is reset, and the gas pressure in the suction cup 5 becomes smaller. Under the action of the external atmospheric pressure, the suction cup 5 sucks the inner wall of the pipe tightly. As the wheel 4 moves, when it is necessary to pull out the suction cup 5, the installation tube 803 moves away from the suction cup 5 and compresses the compression spring three 808. The compression spring three 808 drives the baffle 807 and the air intake pipe 806 to move, and the air vent 80601 contacts the external atmosphere, and the external atmosphere enters the suction cup 5. When the pressure in the suction cup 5 is consistent with the atmospheric pressure, the suction cup 5 can be easily pulled out, reducing the resistance to pulling out the suction cup 5. Therefore, while ensuring that the wheel 4 is sucked tightly to the pipe wall, it can also prevent the suction cup 5 of the wheel 4 from being sucked too tightly to the pipe wall, which causes too much resistance to the rotation of the wheel 4.
