[0039] Working principle: first push the handrail 304 to drive the mobile frame 100 to move to the work site, then rotate the wheel to drive the screw 201 to rotate, and drive the two connecting sleeves 202 to move toward each other to adjust the distance between the two connecting sleeves 202, and then adjust the distance between the two plug plates 218, so as to adapt to the clamping and placement of wellbores of different diameters. After adjusting to the appropriate distance, press the foot pedal 225 to control the extension and retraction of the hydraulic cylinder 221, and adjust the height of the two plug plates 218, so as to unload the wellbores stacked at different heights.

[0040] Then the cylinder 219 is driven to drive the support plate 220 to move forward, and then the two plug plates 218 are moved to insert into the bottom end of the shaft to be unloaded, so that the shaft is inserted on the two plug plates 218. After the two plug plates 218 are fully inserted into the bottom end of the shaft, the shaft will fall into the two connecting frames 204 along the two unloading platforms 217 and the limit seats 215 using the arc-shaped protrusions on the upper ends of the plug plates 218. The rear end of the shaft will first lean against the front end of the support plate 220, and the support plate 220 will be used to provide preliminary support for the shaft to prevent the shaft from tipping over.

[0041] The gravity of the wellbore itself will press the pressure plate 205 downward, and the downward movement of the pressure plate 205 will squeeze the hydraulic oil in the first oil cylinder 206 downward, and the hydraulic oil in the first oil cylinder 206 will be pressed into the second oil cylinder 208 through the connecting pipe 207, thereby pushing the piston plate 210 in the second oil cylinder 208 to move upward, driving the top plate 209 at the upper end of the piston plate 210 to move upward, and the upward movement of the top plate 209 will press the upper arc plate 211 upward, driving the arc plate 211 to move toward the wellbore, and then the arc plates 211 on both sides drive the fixed plates 213 on both sides to move toward each other, driving The clamping plate 214 on the fixed plate 213 clamps and fixes the wellbore, thereby converting the pressing amount of the pressure plate 205 into the displacement of the two fixed plates 213 approaching each other, so that the clamping plate 214 is used to firmly clamp and limit the wellbore. The greater the gravity of the wellbore itself, the greater the clamping force of the clamping plate 214 on the wellbore, which improves the clamping effect of wellbores of different weights and enhances the stability of wellbores of different weights when clamping and fixing. Therefore, when transporting wellbores of different weights, the clamping force of the wellbore is increased, the stability of wellbore transportation is improved, shaking is prevented, and the practicality of the device is improved.
