Abstract
The utility model discloses a toppling prevention device of a hoisting swivel elevator of a rotary drilling rig, which comprises a steel wire rope connecting end and a drill rod connecting end. One end of the steel wire rope connecting end is provided with a connector, a tubular cavity is disposed inside the connector, a resetting device is mounted in the tubular cavity, a through hole is disposed at one end, which is far away from the steel wire rope connecting end, of the connector, and a cylindrical projection is disposed at one end of the drill rod connecting end, extends into the tubular cavity from the through hole and is rotationally connected with the connector. The toppling prevention device can guarantee that the hoisting swivel elevator is coaxially perpendicular to a drill rod when the drill rod contacts with the bottom of a well even if a steel wire rope is released excessively, prevents early-stage damage to the drill rod due to rotation of the steel wire rope during rotation of the drill rod, and can reduce over-release volume of the steel wire rope due to the fact that an internal extension spring can overcome friction force generated by a sliding pair due to mud while the steel wire rope is tensioned.
