Rope coring and arranging winch with heavy hook falling freely

Abstract

The invention relates to a rope coring and arranging winch with a heavy hook falling freely. The rope coring and arranging winch comprises a coiling block assembly, a brake, a change gear speed regulating chain, a gear shaft bracket, a left support plate, a right support plate, a base and a rope arranger, wherein the coiling block assembly is in a built-in structure; a servo motor, a planetary reducer and a clutch are embedded in a winch drum; the coiling block assembly is fixed on the base by the left support plate and the right support plate; the left end of the coiling block assembly is connected with the brake; the left end of an output shaft of the brake is connected with the change gear speed regulating chain; a bi-directional screw of the rope arranger is arranged at an output end of the change gear speed regulating chain; when the winch drum rotates for a cycle, the rope arranger moves for one rope width in an axial direction of a guide shaft; the rope arranger makes counter motion when reaching the edge of the winch drum; and the rope arranger makes back-and-forth motion to fulfill a purpose of uniformly and orderly arranging a rope. The winch has the advantages of compact structure, convenience in starting, safe and reliable operation, energy source saving, and the like, and is suitable for tasks of fishing coring drilling tools in deep hole and complex formation coring drilling construction.

Description

technical field [0001] The invention relates to a drilling auxiliary equipment, in particular to a heavy hook free-falling rope core-taking winch. Background technique [0002] Due to its lifting and traction characteristics, the winch is widely used in various industrial machinery and equipment such as lifting transportation, construction, port terminals and geological exploration. Judging from the development status of geological exploration technology at home and abroad, there is no geological exploration technology that can replace core (sample) drilling technology, and can finally accurately determine a series of physical and chemical parameters such as the grade, burial depth, and reserves of underground mineral resources. Therefore, core (sample) drilling technology still plays an irreplaceable role in future geological prospecting. [0003] Due to the high drilling efficiency, long life of the drill bit, the labor intensity of workers is greatly reduced, and the acc...

AI Technical Summary

Problems solved by technology

[0005] 1. Power is required for both lifting and lowering, and it does not have the function of lowering the heavy hook

[0006] 2. The wire rope is unevenly wound on the winch drum, and the rope arrangement is disordered, which makes the wire rope easy to cause plastic deformation and scratches on the surface of the drum, which not only shortens the service life of the wire rope, but also lays the groundwork for broken rope, dropped drill or even greater safety accidents.
