Embodiment Construction

[0030] The core of the present invention is to provide a lifter for a rotary drilling rig, which can meet the requirements of smoothly delivering high-pressure gas or liquid to the drill bit of the rotary drilling rig, and effectively avoids the Withstand torsional load to ensure the service life of the delivery pipeline. Another core of the present invention is to provide a rotary drilling rig comprising the above-mentioned lifter.

[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Please refer to Figure 2 to Figure 5 , figure 2 It is a schematic cross-sectional view of a specific embodiment of the lifter provided by the present invention; image 3 for figure 2 Schematic side view of the lifter shown; Figure 4 for figure 2 Schematic front view of the lifter show...

Abstract

The invention discloses a hoister, which comprises an upper connector (21), a middle connector (22) and a lower connector (23), wherein the middle connector (22) is fixedly connected to the lower connector (23) and is rotatably connected to the upper connector (21); the upper connector (21) is provided with a first channel (211); the middle connector (22) is provided with a second channel (221); the lower connector (23) is provided with a third channel (231); the extending directions of the three channels are all parallel to the axis of the hoister; the first channel (211) is communicated with the second channel (221) through an annular air storage slot (24) therebetween; and the second channel (221) is communicated with the third channel (231). The hoister of the invention can meet the demand of smoothly transmitting high-pressure air or liquid to a drill of a rotary drilling rig and can efficiently prevent a conveying pipe from bearing the torsion load so as to ensure the service life of the conveying pipe. The invention also discloses a rotary drilling rig of the hoister.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a lifter for a rotary drilling rig. In addition, the present invention also relates to a rotary drilling machine comprising the above-mentioned lifter. Background technique [0002] As a construction machine suitable for hole-forming operations in building foundation projects, rotary drilling rigs are widely used in basic construction projects such as municipal construction, highway bridges, and high-rise buildings. [0003] Due to the advantages of large installed power, large output torque, large axial pressure, flexible maneuverability, high construction efficiency and good hole-forming quality, rotary drilling rigs have been widely used in the field of engineering construction and become the main hole-forming equipment for engineering construction. At the same time, the rotary drilling rig can also be used in dry (cooperate with short auger drill), or wet (coop...
