Abstract

The invention discloses a power head buffering device for a rotary drilling rig. The power head buffering device includes an inner ring, an outer ring slidably connected to the inner ring, and an annular shock absorbing device sleeving the outer ring, the inner wall of the inner ring sleeves the outer wall of the outer ring, the shock absorbing device is arranged between the bottom wall of the inner ring and the bottom wall of the outer ring, the shock absorbing device includes a plurality of shock absorbing modules, each of the shock absorbing modules includes a fixing plate, two baffle blocks, and a shock absorbing spring. When a single shock absorbing spring is damaged and needs to be replaced, only the shock absorbing module where the shock absorbing spring is located needs to be disassembled to complete the replacement, and thus the replacement of the shock absorbing spring is very convenient.

Description

technical field [0001] The invention relates to a buffer device for a power head of a rotary drilling rig, belonging to the technical field of rotary drilling rigs. Background technique [0002] The power head of the rotary drilling rig is the main working part of the rotary drilling rig. It is subjected to a large load and load changes. Therefore, during the construction process of the rotary drilling rig, there are many failures of the power head, and failures occur Finally, it often needs to be shut down for maintenance, which brings great economic losses to the owner. The power head device is the most important working part of the drilling rig, which is composed of a hydraulic motor, a reducer, a power box, a buffer device, a sliding frame, a connecting plate, a pressure plate or a casing driver. The buffer device is mainly used to buffer the vibration impact of the entire working device when the drill pipe is normally drilled and to protect the equipment when abnormal ...
