Problems solved by technology

[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, full-casing full-rotary drilling rigs have appeared at home and abroad. The clamping method of the casing clamping device has small clamping force, poor alignment, complex diameter-changing mechanism, and inconvenient disassembly and assembly, etc., which affect the construction progress.

Embodiment Construction

[0009] Such as figure 1 , 2 As shown, the working column structure of the full-turn drilling rig includes a guide column 4 and a sliding column 2 arranged outside the guide column 4 . One end of the sliding column 2 is provided with a first nylon sleeve 3 , and the other end is provided with another first nylon sleeve 5 for buffering between the guide column 4 and the sliding column 2 to reduce friction and vibration. The outer end of the sliding column 4 close to the first nylon sleeve 3 is also covered with a second nylon sleeve 1, which is used to reduce the friction and collision vibration between the column structure of the full-turn drilling rig and the surrounding components or the box after installation. Both the first nylon sheath (3, 5) and the second nylon sheath 1 are made of nylon, the cost is relatively low, and the processing and manufacturing are relatively convenient.

Abstract

The invention relates to an upright post structure for operation of a fully slewing drilling machine. The upright post structure for the operation of the fully slewing drilling machine comprises a guide post and a sliding upright post arranged outside the guide post. The upright post structure for the operation of the fully slewing drilling machine also comprises a first nylon sleeve arranged between the guide post and the sliding upright post. In the working process, the first nylon sleeve achieves the protective effects of damping, reducing friction and the like, is convenient to process and manufacture, and is low in cost.

Description

technical field [0001] The invention relates to a column structure, in particular to a column structure for a fully 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, full-casing full-rotary drilling rigs have appeared at home and abroad. The clamping method of the casing clamping device has small clamping force, poor alignment, complex diameter-changing mechanism, and inconvenient disassembly and assembly, etc., which affect the construction progress. Contents of the invention [0003] ...
