[0002] With the continuous acceleration of my country's infrastructure construction, more and more constructions are being carried out in various complex geological environments such as plateaus, mountains, hills, beaches, rivers, lakes and tidal flats. During on-site construction, quicksand, karst caves, rock formations, etc. are often encountered underground. Various complex geological conditions, traditional excavation tools and construction methods are difficult to construct
In recent years, there have been full-casing full-rotary drilling rigs at home and abroad, which are a new type of pile engineering machinery. However, the rotary cone used on the machine has a split structure connected by bolts to the ring gear and the cone. After high-load work, it is easy to cause the bolts to loosen or be damaged, and the fit between the ring gear and the cone will also become loose
The looseness of the rotary cone has a serious impact on the transmission and clamping of the machine
Especially when the machine is under high-strength construction, this defect is particularly prominent

[0013] A rotary cone for a full-casing full-rotary drilling machine includes a rotating part 1 and a gear part 2 . The rotating part 1 and the gear part 2 are integrated. The rotating part 1 is roughly ring-shaped. The gear part 2 is formed on the outside of the rotating part 2 and is a ring gear made by processing, which is used to mesh with the external gear to drive the rotating part 1 to rotate. When working, the hydraulic motor 3 starts to drive the reducer 4 to rotate. The reducer 4 drives the driving gear 5 to rotate through the output shaft. The driving gear 5 meshes with the idler 6 to drive the idler 6 to rotate. It drives the entire rotary cone to rotate, and then clamps the casing rotation operation of the full-casing full-rotary drilling rig.
[0014] The rotary cone of the present invention is processed outside the rotating part 1 to form the gear part 2 of the ring gear structure. Structurally, the rotating part 1 and the gear part 2 are integrated without any c...

Disclosed is a rotary cone for an all-casing full-rotating drilling machine. The rotary cone comprises a rotary portion and a gear portion disposed on the outer wall of the rotary portion. The rotary portion and the gear portion are in an integral structure, and the gear portion is used for being meshed with an external gear to drive the rotary portion to rotate. According to the rotary cone for the all-casing full-rotating drilling machine, the rotary portion and the gear portion are in the integral structure, so that loosing of the rotary cone between the rotary portion and the gear portion due to loosing or damage of bolts of a separated structure connected through the bolts can be prevented, and the operational reliability is high.
Description
technical field [0001] The invention relates to a rotary cone, in particular to a rotary cone used on a full casing full rotary drilling rig. Background technique [0002] With the continuous acceleration of my country's infrastructure construction, more and more constructions are being carried out in various complex geological environments such as plateaus, mountains, hills, beaches, rivers, lakes and tidal flats. During on-site construction, quicksand, karst caves, rock formations, etc. are often encountered underground. Various complex geological conditions, traditional excavating tools and construction methods are difficult to construct. In recent years, there have been full-casing full-rotary drilling rigs at home and abroad, which are a new type of pile engineering machinery.
