Each upper connecting plate 23 is provided with motor bases 25 and 26, and each motor base 25 and 26 is respectively fixed with a motor 27. During work, the three pinion shafts 21, 30 and 32 are driven to rotate by the three motors 27, so that the position adjustment mechanism rotates along the transmission teeth to achieve the purpose of adjusting the circumferential position of the mechanical arm.
 like Figure 8 and Figure 9 As shown, the lifting mechanism is a connecting rod telescopic mechanism, which is used to directly contact the human body and protect the person in the deep well rescue device. The lifting mechanism includes three T-shaped beams 11 with a length of about 1500mm, and one end of each T-shaped beam is connected with the positioning mechanism through a connecting piece 12, and the connecting piece 12 can be a screw or a pin.

A nut is engaged on the leading screw 19, and a slide block 12 is fixed on the nut, and the slide block 12 is sleeved on the T-shaped beam through a through hole thereon. During work, the rotation of the leading screw 19 causes the nut to move up and down along the leading screw 19, so that the slide block moves up and down with the T-shaped beam as the guide rail. A transmission rod assembly is connected to the slide block, and the transmission rod assembly may include two push rods 14 .

 The communication device includes a lighting system, a camera and a communication system, and circuit boards corresponding to the lighting system, the imaging system and the communication system are connected to a computer to obtain information about people trapped underground.
 The working process of the deep well rescue device of the present invention will be described below.
 Tie the rope on the rope fixing ring 45, hang it vertically from the ground into the well, monitor the camera, make the rescuer stop above the trapped person, drive the motor 7 of the positioning mechanism, drive the lead screw 39 to rotate, and the positioning mechanism launches, so that The wheels 42 contact the well wall and do not shake down the well, and the device completes the positioning. The rescuers on the ground observed the posture of the trapped person in the well through the camera, looking for three gaps of about 20mm. After finding a suitable gap, drive the motor 27 of the positioning mechanism to make the positioning mechanism work, and the positioning mechanism adjusts the circumferential positions of the three groups of mechanical arms so that the three groups of mechanical arms are aligned with the gaps found. After the position is adjusted, the rope is slowly lowered, and the rescuer moves down slowly along the well wall, so that each mechanical arm extends under the trapped person, and the mechanical claws of the lifting mechanism are in a contracted state at this time. When the mechanical arm stretched into the position that the fixing part 29 arrived below the trapped person, the leading screw 19 of the lifting mechanism was driven to rotate, so as to push the support rod 17 through the downward movement of the push rod 14 until the upper part of the support rod 17 was close to the level position, so that the mechanical rotation of the lifting mechanism is in the unfolded state, and the trapped person is surrounded by the mechanical claws of the lifting mechanism. Then, the screw 8 that drives the clamping mechanism rotates, and the connecting rods 43, 44, 46 are pushed by the push plate 9 so that the clamping mechanism pivots in the radial direction to clamp the trapped person. Finally, the motor 7 that drives the positioning mechanism puts up the positioning mechanism, and the people and the deep well rescuer are pulled out of the well by the rope, and the rescue task is completed.
