Abstract

The invention provides a lifting device and method for liftable in-well equipment in an in-situ leaching uranium mining mine. The lifting device comprises a frame, a power device, a lifting device and a pipe coiling device. The lifting device ascends and descends through a hydraulic device, and meanwhile power is provided for a winch. The problems that due to the fact that the gravity center of an in-well equipment lifting device is too high, trafficability is poor, and in-well equipment lifting operation cannot be conducted on complex terrains are solved, the in-well equipment lifting efficiency is improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention belongs to the field of in-situ leaching uranium mining well site process drilling equipment maintenance field, and in particular relates to an in-situ leaching uranium mine lifting device and method for lifting equipment in the well. Background technique [0002] Well equipment lifting technology is CO 2 +O 2 One of the core technologies of the in-situ leaching uranium mining engineering wellsite process is to lift the well pipe, well cable and multi-stage submersible pump through the well equipment lifting device. After the repair by the maintenance personnel, the pipe in the pumping well, the cable in the well and the multi-stage submersible pump are lowered into the borehole through the hoisting device of the equipment in the well. The uranium-containing solution is collected into the centralized control room through submersible pumps, well pipes, and surface pipes. [0003] In the process of production and operation, submersible p...
