Description
Technical Field
The utility model belongs to the technical field of the drilling rod, concretely relates to colliery is drilling tool in pit salvages construction and uses drilling rod.
Background
Receive the complicated or drilling tool quality influence of coal seam condition, can appear sticking the brill in drilling process inevitable, embrace and bore or bore downthehole accidents such as disconnected, directional drilling machine hole bottom motor and drilling rod expense are high, cause huge loss, pass through the screw thread with fishing rod now often, salvage the drill bit, but the drill bit is in underground depths, the condition underground is not seen to the manual work, the while is to the unable operation of underground structure, the unable accurate butt joint of screw thread of fishing rod and drill bit, let the fishing degree of difficulty increase.
SUMMERY OF THE UTILITY MODEL
The utility model provides a colliery is drilling tool in pit salvages construction and uses drilling rod, lets salvage butt joint convenience more, and more accuracy has improved the speed and the efficiency of salvaging.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model provides a colliery is drilling tool in pit and is salvaged drilling rod for construction, including the salvage section, the salvage section is vertical to be arranged, salvage section bottom is equipped with the interlude, interlude bottom is equipped with the drill bit, drill bit top relative position is equipped with the drill bit internal thread, the relative position in interlude bottom is equipped with the interlude external thread, interlude top relative position is equipped with the interlude internal thread, salvage section bottom relative position is equipped with salvage section external thread, salvage section inside is equipped with a plurality of gas circuits, the gas circuit is vertical to be arranged, a plurality of gas circuit circumference evenly distributed are inside the salvage section, all be equipped with a plurality of gas pockets on every gas.
Further, the air holes are arranged obliquely downward.
Furthermore, the external thread of the fishing section is matched with the internal thread of the middle section, and the external thread of the middle section is matched with the internal thread of the drill bit.
Furthermore, the diameters of the fishing section, the middle section and the drill bit are equal.
Further, the top of the air path is communicated with an air pump.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses in, through setting up a plurality of gas circuits and gas pocket, let the inside blowout high-pressure gas of gas pocket, gas pocket spun gas impact drilling inner wall lets the section of salvaging be located the central point of drilling and puts to let the central line of salvaging the section align with the central line of well festival, let the butt joint convenience more of salvaging section and well festival, more accuracy has improved the speed and the efficiency of butt joint.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view of the fishing section.
In the figure: 1. the fishing tool comprises a fishing section, 2 parts of a middle section, 3 parts of a drill bit, 4 parts of drill bit internal threads, 5 parts of middle section external threads, 6 parts of middle section internal threads, 7 parts of fishing section external threads, 8 parts of a gas circuit and 9 parts of a gas hole.
Detailed Description
Example (b): as shown in fig. 1 and 2, the fishing tool comprises a fishing section 1, the fishing section 1 is vertically arranged, the bottom of the fishing section 1 is provided with a middle section 2, the bottom of the middle section 2 is provided with a drill bit 3, the top relative position of the drill bit 3 is provided with a drill bit internal thread 4, the bottom relative position of the middle section 2 is provided with a middle section external thread 5, the top relative position of the middle section 2 is provided with a middle section internal thread 6, the bottom relative position of the fishing section 1 is provided with a fishing section external thread 7, the fishing section 1 is internally provided with a plurality of gas paths 8, the gas paths 8 are vertically arranged, the plurality of gas paths 8 are circumferentially and uniformly distributed inside the fishing section 1, each gas path 8 is provided with a plurality of gas holes 9, and. The air hole 9 is obliquely and downwards arranged, the fishing section external thread 7 is matched with the middle section internal thread 6, the middle section external thread 5 is matched with the drill bit internal thread 4, the diameters of the fishing section 1, the middle section 2 and the drill bit 3 are equal, and the top of the air path 8 is communicated with the air pump.
The working process is as follows: before drilling, earlier with middle section 2 and 3 fixed connection of drill bit, when needs salvage the drill bit, will salvage section 1 and go deep into drilling, then with gas circuit 8, be connected with the air pump that corresponds, when 1 bottom of salvage section contacts with middle section 2 tops, start the air pump, the air pump is with inside air input gas circuit 8, finally spout through gas pocket 9, the even distribution of gas pocket 9 is on salvage section 1 surface, gas pocket 9 spun gas strikes the drilling inner wall, let salvage section 1 be located the central point of drilling and put, middle section 2 should also be located the central point of drilling and put, rotatory salvage section 1 downwards this moment, salvage section 1 and middle section 2 just can accomplish the butt joint.
