Abstract
The utility model discloses a quickly-disassembling device for a circular-arc bead drill pipe. The quickly-disassembling device comprises a three-edge shaft and a three-side sleeve, wherein the three-edge shaft is divided into a circular section, a spacing disc section, a prism section and an external thread section; the circular section is used to be connected with a drilling machine chuck and carries out circumferential rotation or axial movement along with the chuck; the external thread section is used to be connected with the circular-arc bead drill pipe; and the shape and the size of the section of the prism section are the same with the shape and the size of the section of the circular-arc bead drill pipe. When the disassembling mode of the device disclosed by the utility model is adopted, the three-edge shaft and the three-side sleeve are installed on the drilling machine power head chuck after the drilling construction is finished; the power head chuck is pushed to a drill pipe position; the chuck is forwards rotated to enable the three-edge shaft to be connected with the drill pipe but not to be screwed down; after the drill pipe is dragged to one drill pipe position, the three-side sleeve is slid to the connection position of the three-edge shaft and the drill pipe; a drilling machine gripper is clamped; the drilling machine chuck is reversely rotated; the connection of the first drill pipe and the second drill pipe is opened; manual reverse rotation is carried out; the first drill pipe is taken down; and the above steps are repeated until all drill pipes are taken down. According to the quickly-disassembling device disclosed by the utility model, the potential safety hazard for disassembling is greatly lowered while the drill pipe disassembling efficiency is improved.
Description
Technical field
The utility model relates to the drill rig components of using in the mine production, particularly the provision for disengagement of the circular arc fin drilling rod of the hydraulic drill rig of mine construction extraction borehole use.
Background technology
The hydraulic drill rig extraction borehole of in coal (rock) layer, constructing is mainly adopted in the coal mine gas extraction, and coal-bed gas is carried out release, reaches the purpose of administering gas.For a long time, the main drilling rod that adopts cylindrical cross section of extraction borehole construction, the extraction borehole of constructing often need tens to hundreds of root drilling rod, and main drill power head chuck, the clamper of relying on of drilling rod dismounting adopts the dismounting of rig self power.
In recent years, occurred a kind of circular arc fin drilling rod in the coal rock layer drilling construction, this drilling rod is progressively applied in mine because the deslagging space is big, rate of penetration is fast, the bit freezing number of times is few.But circular arc fin drilling rod section configuration, size and common cylindrical shaped drilling rod difference are big; Drilling rod is in unloading process, and drill power head chuck and circular arc fin drilling rod do not match, and can not adopt the dynamical system of former rig to realize dismounting automatically; Must adopt the dismounting of fork spanner manpower; Unloading process length consuming time, labor strength is big, and security incident takes place frequently.
Summary of the invention
The technical problem that the utility model will solve is: overcome the deficiency that existing circular arc fin drilling rod dismounting exists, the provision for disengagement of a kind of circular arc fin drilling rod is provided, to dismantle circular arc fin drilling rod quickly and safely.
The technical scheme of the utility model is following:
A kind of circular arc fin drilling rod quick-release arrangement comprises tripartite cover and triangular axle, tripartite being enclosed within on the triangular axle, and tripartite cover can be done on triangular axle and endwisely slip, but can not do circumferentially to rotate with respect to triangular axle.
Described triangular axle is divided into four sections of cylindrical sections, position-arresting disk, prismatic section, external thread section, and they connect fixing successively.
The cylindrical section of said triangular axle is connected with chuck of rig, circumferentially rotates or moves axially with chuck of rig, and the external thread section of triangular axle is connected with triangular drilling rod; The prismatic section of triangular axle cross sectional shape, size and circular arc fin drilling rod cross sectional shape, measure-alike.
Described tripartite cover can slide into the screwed connection position at triangular axle with after triangular drilling rod is connected, limits triangular and circular arc fin drilling rod and does relative to circumferentially rotating.
Use the utility model, dismounting circular arc fin drilling rod can use rig self power to accomplish, and technology is simple; Easy to operate; Reduce labor intensive simultaneously, shorten the take-down time greatly, reduce the security risk that adopts the fork spanner artificial unloading, application result shows: adopt the utility model; The circular arc fin drilling rod take-down time reduces by 75% on the basis of former technology, stopped the injured accident in the triangular drilling rod unloading process.The utility model is simple in structure, and processing cost is low, and fault rate is low.

Among the figure, triangular axle 1, tripartite cover 2, chuck of rig 3, circular arc fin drilling rod 4, rig clamper 5, borer frame 6, cylindrical section 2-1, position-arresting disk 2-2, prismatic section 2-3, external thread section 2-4.
The specific embodiment
As depicted in figs. 1 and 2, a kind of circular arc fin drilling rod quick-release arrangement comprises tripartite cover 1 and triangular axle 2, and tripartite cover 1 can be done on triangular axle 2 and endwisely slip, but can not do circumferentially to rotate with respect to triangular axle 2.Triangular axle 2 is divided into four sections of cylindrical section 2-1, position-arresting disk 2-2, prismatic section 2-3, external thread section 2-4, adopts between every section to be welded to connect.
Like Fig. 3, shown in Figure 4; The cylindrical section 2-1 of triangular axle 2 is connected with chuck of rig 3, circumferentially rotates or moves axially with chuck of rig 3, and position-arresting disk 2-2 cooperates with the end face of chuck of rig; Be used for spacingly, the external thread section 2-4 of triangular axle 2 can be connected with circular arc fin drilling rod 4; Prismatic section 2-3 cross sectional shape, size and circular arc fin drilling rod 4 cross sectional shapes, measure-alike of triangular axle 2.Tripartite cover 1 can slide into the screw thread position at triangular axle 2 with after circular arc fin drilling rod 4 is connected, limits triangular 2 and circular arc fin drilling rod 4 simultaneously and does relative to circumferentially rotating.
The mode of occupation of this provision for disengagement is following:
1) creeps into to design attitude; Dismounting water is distinguished axle, and triangular axle 2 and tripartite cover 1 are installed on chuck of rig 3, the cylindrical section 2-1 of the triangular axle 2 of chuck of rig 3 chuckings; And promote comprehensively to circular arc fin drilling rod 4 positions; Chuck of rig 3 is just changeing, and the external thread section 2-4 that makes triangular axle 2 is connected with circular arc fin drilling rod 4 but does not tighten interior 4 to the run of steel positions of circular arc fin drilling rod of tractor hole;
2) slide tripartite cover 1 to triangular axle 2 and circular arc fin drilling rod 4 link positions, chucking rig clamper 5, being connected of first drilling rod and second drilling rod unclamped in chuck of rig 3 counter-rotatings;
