Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a casing device for a full-rotary drilling rig, mainly to solve the problem that the rotary drum will not collect the broken sand and soil when using the full-rotary drilling rig. Sandstone and soil are compacted with the drilled hole wall, which increases the pressure of the full-turn drilling rig to break the wall again, which affects the use of the full-turn drilling rig

Embodiment 1

[0033] refer to Figure 1-Figure 5 , a cylinder protection device for an azimuth drilling rig, comprising an outer cylinder 1, a plurality of connecting rings 2 are fixed on the circumferential inner wall of the outer cylinder 1 by bolts, and the same inner cylinder is inserted between the circumferential inner walls of the connecting rings 2 3. The double-layer design of the outer cylinder 1 and the inner cylinder 3 can collect the crushed sand and soil in the interlayer between the outer cylinder 1 and the inner cylinder 3, so as to avoid the damage of the outer cylinder 1 and the inner cylinder 3. The rotation will compact the broken sand, gravel and soil against the cave wall, reducing the pressure of the azimuth drilling rig to break the wall again, and improving the practicability of the azimuth drilling rig. The bottom of the outer cylinder 1 and the inner cylinder 3 are provided with multiple The design of the drill 4 and the double-layer drill 4 can increase the rotat...

Embodiment 2

[0037] refer to Figure 6-Figure 7 , a cylinder protection device for an azimuth drilling rig, comprising a plurality of heat dissipation holes 26 on the circumferential outer wall of the outer cylinder body 1, an annular inclined surface cover 27 fixed on the circumferential outer wall of the outer cylindrical body 1 by bolts, and the heat dissipation holes 26 are located in the annular inclined surface cover. Inside 27, the heat dissipation hole 26 can be partitioned by the annular inclined surface cover 27 to prevent the entry of rainwater and dust, which increases the use of the azimuth drilling rig. A heat dissipation ring 29 is fixed on one side by bolts, and the heat dissipation ring 29 is in contact with the circumferential inner wall of the outer cylinder 1. The heat generated by the friction between the outer cylinder 1 and the inner cylinder 3 and the sand and stone can be conducted to the outer cylinder 1 and the inner cylinder 3 through the heat conduction ring 28....

Abstract

The invention relates to the technical field of full-slewing drilling machines, and discloses a pile casing device of a full-slewing drilling machine, which comprises an outer cylinder body, a plurality of connecting rings are fixedly connected to the circumferential inner wall of the outer cylinder body, the same inner cylinder body is inserted between the circumferential inner walls of the connecting rings, and a plurality of drilling tools are arranged at the bottoms of the outer cylinder body and the inner cylinder body. The top ends of the outer barrel and the inner barrel are fixedly connected with the same top ring, the upper surface of the top ring is fixedly connected with an annular shell, the upper surface of the top ring is movably connected with a plurality of sliding rods, the sliding rods penetrate through the connecting ring and the annular shell, and the bottom ends of the sliding rods are fixedly connected with an annular push plate. According to the full-slewing drilling machine, crushed gravel and soil can be collected in an interlayer of the outer barrel and the inner barrel, so that the situation that the crushed gravel and soil are compacted with a hole wall due to rotation of the outer barrel and the inner barrel is avoided, the pressure of wall breaking of the full-slewing drilling machine again is reduced, and the practicability of the full-slewing drilling machine is improved.

Description

technical field [0001] The invention relates to the technical field of full rotary drilling rigs, in particular to a casing protection device for full rotary drilling rigs. Background technique [0002] As we all know, an azimuth drilling rig is a machine that is driven by a power device to rotate a rotary cone, and the rotary cone clamps the sleeve to drive the sleeve to rotate and cut the soil downward. It has been widely used in the field of The azimuth drilling rig includes a base and a rotary driving device. It is found that the existing azimuth drilling rig lacks protection in use. Therefore, a casing protection device for the azimuth drilling rig is provided. [0003] At present, most of the existing azimuth drilling rigs have the following shortcomings: when using the azimuth drilling rig, because the rotating drum cannot collect the broken sand and soil, the rotating drum will mix the sand and soil with the drilled holes. Wall compaction increases the pressure of t...
