Abstract
The utility model discloses a drilling liner hanger for repair and reconstruction of a casing damage well shaft, and relates to the field of drilling liner hangers, the drilling liner hanger comprises a hanger main body, the hanger main body comprises a mounting pipe, the outer surface of the mounting pipe is provided with a plurality of uniformly distributed placing grooves, and clamping parts are rotatably mounted in the placing grooves. The clamping component comprises a first supporting arm, a second supporting arm is slidably clamped in the first supporting arm, a plurality of evenly-distributed spherical grooves are formed in the first supporting arm, and a placement groove is formed in the end, close to the first supporting arm, of the second supporting arm. When the hanger is used, the second supporting arm can be taken out only by dragging the second supporting arm to the maximum position, then rotating the second supporting arm to the maximum position, pushing the second supporting arm and then rotating the second supporting arm for a small circle, replacement of quick-wear parts of the hanger can be achieved without a tedious disassembly process, operation is easy, and the use cost of the hanger is reduced.
