Full-casing full-slewing drilling machine device

Abstract

The embodiment of the invention provides a full-casing full-slewing drilling machine device, and relates to a mechanical equipment technology in a low-clearance construction environment. The full-casing full-slewing drilling machine device comprises a main machine frame, a slewing drilling mechanism and a controller, a casing hole used for being matched with a casing pipe is formed in a bottom plate of the main machine frame; a slewing drilling device is connected to the top of the main machine frame; the slewing drilling mechanism is provided with a drilling assembly, a detection piece and an adjusting assembly. The drilling assembly is used for driving the casing pipe to drill; the adjusting assembly is connected between the drilling assembly and the main machine frame; the detection piece is arranged on the main machine frame; the controller is electrically connected with the detection piece and the adjusting assembly, and the controller is used for controlling the adjusting assembly to adjust the perpendicularity of the casing pipe according to a detection result of the detection piece. According to the full-casing full-slewing drilling machine device, under the low-clearance construction environment, automatic taking and drilling of the casing pipe can be realized, automatic deviation correction of the casing pipe in the casing pipe drilling process is realized, and drilling and soil sampling can be realized at the same time.

Description

technical field [0001] The present application relates to mechanical equipment technology in a low clearance construction environment, in particular to a full-casing full-rotation drilling rig device. Background technique [0002] With the acceleration of the urban construction process and the continuous improvement of the road network, the enclosure structure construction, foundation reinforcement treatment and construction under the condition of limited clearance under the high-speed rail, municipal, bridge and other infrastructure, and can not affect the safety and stability of the infrastructure Operation is a problem that has plagued the construction industry for a long time. [0003] Full-casing full-rotary drilling rig generally refers to a device that uses a full-rotary drilling rig to apply torque and vertical load to the casing to make the casing rotate and pull out while rotating in the formation. Such as figure 1 Shown is the existing full-casing full-rotary dr...

Problems solved by technology

[0004] During the research process, the inventors found that uneven force applied due to changes in geological conditions in the initial stage of casing placement or during drilling can easily lead to casing inclination, which in turn affects the quality of the pile.
