Background
The rotary drilling rig is a commonly used construction machine in building foundation construction and is mainly used for construction of building pile foundations. The elevator is an important part between a drill rod and a steel wire rope of the rotary drilling rig, an upper joint of the elevator is connected with the steel wire rope, a lower joint of the elevator is connected with the drill rod, the steel wire rope, the elevator and the drill rod are in a straight line during normal operation, and the upper joint and the lower joint of the elevator can rotate relatively. The elevator has two main functions, namely, the elevator transmits the lifting force of a steel wire rope to lift or lower a drill rod; and secondly, the rotation of the drill rod during working is isolated, namely, the steel wire rope is ensured not to rotate along with the rotation of the drill rod, so that the service life of the steel wire rope can be protected and prolonged. In order to realize the functions of the two points of the elevator, the vertical state between the elevator and the drill rod connecting plate is kept when the rotary drilling rig drills; if the elevator inclines relative to the drill rod connecting plate, especially when the upper joint of the elevator leans against the inner wall of the outer section of drill rod, the upper joint and the lower joint of the elevator rotate together along with the drill rod, the isolation rotation function fails, and the drill rod can drive the steel wire rope to rotate together to cause the steel wire rope to be 'stressed' or 'broken' during the drilling work of the rotary drilling rig, so that the steel wire rope is easy to damage. However, in actual operation, the steel wire rope is often longer than the actually required lowering length, so that the elevator leans against the inner wall of the outer section of drill rod by rotating and inclining around the pin shaft of the drill rod connecting plate, thereby causing the function failure of isolation rotation and generating potential safety hazards.
