The invention provides a single-stage efficient emergency cutting tool and an assembling method thereof. The single-stage efficient emergency cutting tool comprises a first part, a starting device, a second part, an emergency cutting device, a third part and a safety device. One end of the starting device is connected with the emergency cutting device and the other end is connected with the hand pump; the starting device is used for compressing a disc spring in the emergency cutting device of the second part, and elastic potential energy is provided for well descending cutting of a cutting tool in the emergency cutting device through the disc spring. The emergency cutting device adopts a disc spring mechanical energy storage and release principle to quickly cut a steel wire or a cable through a cutting tool; the safety device is installed at the front end of the emergency cutting device, plays a role in safety protection in the assembling process and plays a role in misoperation prevention before cutting. According to the invention, steel wires or cables can be safely and efficiently cut in a high-viscosity fluid well and an inclined well, and a solid guarantee is provided for the success rate and reliability of operation.

The utility model discloses intelligent module hoisting equipment, and relates to the technical field of hoisting equipment. The device comprises a mounting base and a connecting disc, a mounting block is fixedly connected to the center of the side end of the mounting base, a containing cavity is formed in the position, close to the top end, of the interior of the mounting block, a plurality of taking and placing grooves are formed in the position, close to one side, of the top end of the mounting block, connecting shafts are arranged in the taking and placing grooves, and a disc is fixedly connected to the top end of each connecting shaft. A circular groove is formed in the center of the top end of the disc, a first mounting groove is formed in the center of the bottom end of the circular groove, and a first magnet is arranged at the position, located at the first mounting groove, of the bottom end of the circular groove; when the electric hoist is used, the electric hoist body is moved to drive the connecting disc to move to the position above a needed clamp disc and be clamped, then the electromagnet is started to attract the disc, and finally the disc is taken out of the taking and placing groove, the whole operation process is simple and smooth, taking of a clamp can be rapidly completed, and the preparation efficiency of hoisting operation is improved.
