Problems solved by technology

[0003] In order to solve the problem of small drilling caliber in the actual drilling operation, the present invention provides a rotary drilling frame structure for super large caliber drilling rig, which is One of the key components of the ultra-large-diameter drilling rig. This structure can not only install the two major components of the drilling rig, the drilling head structure and the discharge and suction structure, for drilling and discharge operations, but also its water and electricity pipelines and passages. Installed inside, it has simple structure, flexible rotation, large carrying capacity and low energy consumption

Abstract

Rotary Drill Stand Structure of Super Large Diameter Drilling Rig , The drill frame structure has a " ┴ ”-shaped frame, which is composed of a vertical rotating pipe, a horizontal walking track and a load-bearing track. The axial center of the rotating pipe is a hollow channel, and the channel is filled with sludge and hydropower pipelines. And access, on the outer circumference of the rotating pipe, there are spiral lines and axial sliding keyways from top to bottom. Equipped with driving gears to promote the rotation of the rotating pipe; at the lower end of the rotating pipe, the running track and the carrying track are vertically connected horizontally. And discharge and discharge operations, and its water and electricity pipelines and passages are also installed on it. It has a simple structure, flexible rotation, large carrying capacity, and low energy consumption.

Description

technical field [0001] The invention relates to a structure of a super-large-diameter drilling rig, in particular to a structure of a rotary drilling rig of a super-large-diameter drilling rig. Background technique [0002] At present, most of the drilling rigs used for drilling operations have a relatively small drilling diameter, and the drilling depth is not enough. This is very unfavorable to drilling operations, not only can not meet the requirements of drilling, but also wastes too many resources in the drilling operation process, one is that the existing drilling rigs are large in size and difficult to transport, and the other is that they consume a lot of energy, which increases the drilling cost , especially for super-large caliber drilling rigs. The 3rd, the structure of large drilling rig is complicated, and the whole machine is expensive. This is the case, for example, with the pusher drilling rigs used in subway construction. Contents of the invention [00...
