Abstract
The utility model discloses a two-way drilling plug-type drill pipe, which relates to the field of drill rods for gas drainage, effectively overcomes the drill pipe accidents caused by of the sticking and propping of a drill due to the dislocation of the drill pipe, and is characterized in that the drill pipe and a joint are pressed into a whole body by heating, and drill pipes are assembled by connecting bolts; and the drill pipe and the joint are in a hollow structure, and are in a three-edge arc convex edge hollow shape or a hollow oval shape. The utility model can quickly discharge slag, quickly butt and disassemble, and has simple processing and long service life.
Description
Technical field
The utility model relate to a kind of can the positive and negative two-way plug-in type drilling rod that creeps into.
Background technology
The domestic drilling rod that carries out gas drainage under suction has following several at present:
1. round bur bar, because in the process of creeping into, the deslagging performance is bad, it is stuck drilling rod often to occur, bending is twisted into two parts, and can not pull out phenomenon, has to restart, and has a strong impact on production.
2. auger stem has installed the sheet that screw type rises exactly additional on the basis of round bur bar, has improved deslagging ability, but processed complex, resistance is big during rod boring, and the dismounting difficulty can not be beaten deep hole, and production efficiency is also had very big influence.
3. China's utility model patent discloses a kind of circular arc fin gas drainage under suction drilling rod, and the patent No. is 200720306879.8., has promoted the connectivity problem of deslagging and drilling rod and rig.But because the circular cone screw thread that is connected to of drilling rod is connected, (1) can only rotate single direction forward or backwards and creep into, and can not realize that same drilling rod can creep into also and can oppositely creep into by forward.(2) in the drilling process of reality under the effect of resistance, the phenomenon that the junction of drilling rod and drilling rod can occur misplacing, three ribs of a last drilling rod misplace with three ribs that are attached thereto next the root drilling rod that connects. have a strong impact on deslagging. and also increase the resistance that proposes drilling rod and caused the phenomenon of breaking drilling rod. influence production efficiency.(3) owing to the increase of mine rig power, to the requirement of strength increase of drilling rod, screw mandrel male joint fracture often appears in the drilling rod of screw thread bridging mode, the wearing and tearing of screw head cause drilling rod to come off, leave over drilling rod in the hole, cause boring to scrap, have a strong impact on and produce the wasting manpower and material resources.(4) owing to be the mode that screw thread is connected, the butt joint of drilling rod and dismounting difficulty need clamp, and manpower equipment such as fork run out of space the workman's, have a strong impact on the healthy of coal miner. and wasted a large amount of time, influence is produced.
4. because drilling rod can only one-directional rotation, do not have two-way drilling rod deslagging exhaust of creeping into fast, and the two-way drilling rod that creeps into can the bit freezing bar, crown drill bar, longer service life.
The utility model content
Provide a kind of energy quick deslagging, exhaust, the drilling rod of rapid abutting joint and dismounting.
To achieve these goals, the technical scheme that present technique adopts is: a kind of two-way plug-in type drilling rod that creeps into comprises: 1. hollow drill pipe body, 2. hollow inserted sleeve, 3. caging bolt, 4. special spanner four parts.
The beneficial effects of the utility model are:
1. adopt the hollow inserted sleeve: creep into work but realized that drilling rod Direct/Reverse is two-way, guaranteed the whole uniformity that drilling rod connects, eradicated the inconsistent phenomenon of drilling rod between drilling rod, guarantee the quick exhaust of drilling rod, deslagging, two-way rate of penetration is faster, plug-in type platform joint butt joint and dismounting are more laborsaving quicker, and the root of joint stays a step to be used for airtight hollow drill pipe, can not leak gas or water.
2. caging bolt is used for jointed rod, and it is convenient especially to connect dismounting, and the workman just can finish with a hand.
Since two of bolt with company drilling rod two faces must flush, so the special spanner of needs connect dismounting fast.
The utility model technology, simple in structure, easily manufactured, effectively overcome the stick of tool that causes because of drilling rod dislocation, crown drill and the drilling rod accident that causes.
The beneficial effects of the utility model are the two-way deslagginves fast that creep into, rapid abutting joint and dismounting, and processing is simple, long service life.
Below in conjunction with accompanying drawing the utility model is described in further detail.
The A scheme: drilling rod body one (1) is a triangular circular arc type fin hollow drill pipe, and joint one (2) is a triangular circular arc type fin hollow joint, connecting bolt (3).
The B scheme: drilling rod body two (5) is the oval drilling rod of hollow, and joint two (6) is the oval joint of hollow, connecting bolt (3), and drilling rod body two (5) and joint two (6) all have the connecting bolt hole, when assembling between drilling rod, connect by connecting bolt (3).

The specific embodiment
Further specify the utility model below in conjunction with the embodiment schematic diagram.
Embodiment one: the drilling rod body one (1) of A scheme triangular circular arc type fin hollow drill pipe and joint one (2) the hot pressing one of triangular circular arc type fin hollow joint, T is the hot binding face among Fig. 2, drilling rod body one (1) and joint one (2) all have connecting bolt hole (4), when assembling between drilling rod, connect by connecting bolt (3), promptly become the utility model such as Fig. 2.
B scheme drilling rod body two (5) is the oval drilling rod of hollow, and joint two (6) is the oval joint of hollow, connecting bolt (3), and drilling rod body two (5) and joint two (6) all have connecting bolt hole (4), when assembling between drilling rod, connect by connecting bolt (3).
Further specify the utility model B scheme below in conjunction with the embodiment schematic diagram.
Embodiment two: the drilling rod body two (5) of the oval drilling rod of hollow and joint two (6) the hot pressing one of the oval joint of hollow, T is the hot binding face among the figure, drilling rod body two (5) and joint two (6) have connecting bolt hole (4), when assembling between drilling rod, connect by connecting bolt (3).
