TECHNICAL FIELD
[0001] The utility model relates to the full geologic hole forming and hole expanding field, especially to a drilling machine carrier and hoisting system. BACKGROUND
[0002] The existing large-diameter cast-in-place pile hole forming construction methods all have difficulties that are difficult to overcome:
[0003] 1) Manual hole digging: it is extremely easy to cause casualties in the presence of toxic gas, quicksand, high water level, silt and the like, and it needs to stop work for special treatment in the presence of karst cave and underground river.
[0004] 2) Punch pile machine hole forming: poor hole forming quality, large concrete loss, large environmental pollution, and inability to expand holes, and it needs to stop work for special treatment in the presence of hammer drop and underground river.
[0005] 3) Rotary pile machine hole forming: general hole forming quality, certain concrete loss, and inability to expand holes, and it needs to stop work for special treatment in the presence of inclined rock, hard rock, large karst cave and underground river.
[0006] 4) Sinking pipe rotary pile machine: inability to expand holes, and it needs to stop work for special treatment in the presence of inclined rock, hard rock, large karst cave and underground river.

[0009] 1) The drill bit separation equipment is complex and difficult to operate.
[0010] 2) The hole expanding equipment is fixed on the drill disc, which is easy to damage and difficult to maintain.
[0011] 3) The rotary pipe is easy to bond with concrete, which is not conducive to pipe pulling; the hoisting hole of the rotary pipe is exposed, causing excessive underground water to flow into the rotary pipe, affecting construction.
[0012] 4) When encountering very hard rock layers, the entire pile machine may be lifted.
[0013] 5) pile machine support pair of spin tube lower part is not fixed, causes spin tube to be easy to be off position easily;Pile machine support is separated from the crane, causes hoisting operation to be difficult. Utility model content
