The motor 231 drives the driven gear 233 to rotate through the driving gear 232. This structure is simpler, and many parts are externally mounted and fixed to improve assembly efficiency.

In the actual working process, after the entire structure is assembled, the walking assembly 1010 moves, the base 11 is lifted, the truck is aligned and reversed, so that the truck's carrying plate is at the bottom of the entire structure, the height of the walking assembly 1010 is lowered, and the entire structure is in place to the truck After the wellhead is centered, the oil pollution box is removed from the base 11 to complete the collection of oil pollution, and the oil tube box 40 is opened and laid flat for easy operation. After receiving the oil pipe, the turning motor 60 is activated to make the boom 30 rotate to a vertical state, and then the cantilever crane assembly 20 is activated to hoist the engineering room 50 to the designated position, and then the top drive device moves downward under the traction of the hoist, and the hoist Set on the side of the boom 30 close to the base 11, the hoist moves up and down through the fixed pulley on the upper end of the boom 30 to pull the top drive device. Common equipment in the mining process, under the premise of wellhead centering, the top drive device can grab the oil pipe, and then move up and lift the oil pipe under the action of the hoist. At this time, the shackle device at the wellhead shackles the oil pipe, which is a shackle device It is a common equipment in the process of oil and gas well operations. It is a device that can freely move the oil pipe after detaching it. After the above is completed, the manipulator grabs the oil pipe through the grabbing part 42 and places it on the oil pipe box 40. During the whole operation process, the oil pollution box can be removed. The collection of sewage is completed. After the operation is completed, the sewage is transported away, and the oil pipe is hoisted and transported away by the cantilever crane assembly 20. After the operation is completed, the boom 30 is rotated to be filled horizontally, the oil pipe box 40 is folded into a vertical state, and the oil pollution box and the base are 11. Lock setting, then the upper and lower outrigger assemblies are extended, the base 11 is raised upward, and the truck is aligned, so that the truck's carrying plate is at the bottom of the entire structure, and then the upper and lower outrigger assemblies are retracted, the horizontal outrigger assemblies are retracted, and leave the job The whole device is mechanically driven, with high safety, compact structure and small footprint.
