Abstract
The utility model discloses a mining screw thread type polished drill pipe connection guiding device. The mining screw thread type polished drill pipe connection guiding device comprises a sleeve, wherein the sleeve comprises two separated type semicircular flanged sleeve bodies; two sides of each semicircular flanged sleeve body are respectively connected with fixed plates which are integrally connected with the semicircular flanged sleeve body; each fixed plate is provided with a mounting hole; and the semicircular flanged sleeve bodies are connected with each other through the mounting holes so as to form the sleeve. The two semicircular flanged sleeve bodies which have the same structures are fixedly combined, so that the sleeve of which the diameter is matched with the outer diameter of a drill pipe is formed; and the requirement on the coaxiality of two drill pipes is met by a guiding effect of the sleeve, so that a phenomenon that polished drill pipes deviate when drilling in a lithosphere can be effectively prevented.
Description
Technical field
The utility model relates to mechanical field, and especially a kind of mining screw thread type polished rod drilling rod connects guiding device.
Background technology
In coal mining, in the whole world, main producing coal country has become the principal element of impact safety in production to Gas Outburst problem.At present, the effective means of solution Gas Outburst problem is to adopt the punching gas pre-drainage technology of creeping into.And in actual condition, outside coal seam, having variable thickness, the lithosphere that quality is inhomogeneous, at this moment needs to coordinate alloy bit to hole with screwed connection formula polished rod drilling rod.For example, when practical ZDY series rig carries out creeping in lithosphere, motor by pumping plant by transmission of power to unit head, through drilling rod, reach alloy bit, along with unit head is along frame forward impelling, drill bit cutting rock produces chip, chip is along with current are gone out outside hole, wherein, the inclination angle of boring regulates by head tree, but because lithosphere quality is inhomogeneous, when creeping into, easily cause drilling rod sideslip, before and after making, drilling rod coaxiality error increases, and by head tree, is regulated and is also difficult for meeting axiality requirement, and drilling rod connects difficulty.
Summary of the invention
The purpose of this utility model is: provide a kind of mining screw thread type polished rod drilling rod to connect guiding device, it can effectively prevent that polished rod drilling rod from the situation of sideslip occurring when lithosphere creeps into, to overcome the deficiencies in the prior art.
The utility model is achieved in that mining screw thread type polished rod drilling rod connects guiding device, comprise sleeve, sleeve is two split type semicircular flanges sleeves, in the both sides of each semicircular flanges sleeve, be equipped with the stator being connected as a single entity with it, on each stator, be provided with installing hole, semicircular flanges sleeve connects to form sleeve by installing hole.
The installing hole arranging on the stator of every side is more than 2.The quantity of installing hole, according to the length of sleeve and fixing need to selection, its objective is the reliability connecting between two sleeves in order to guarantee.
Owing to having adopted technique scheme, compared with prior art, it is fixing that the utility model utilizes two identical semicircular flanges sleeves of structure to combine, make it form a sleeve matching with drilling rod external diameter, utilize the guide effect of this sleeve to guarantee two sections of axiality requirements between drilling rod, thereby effectively prevent that polished rod drilling rod from the situation of sideslip occurring when lithosphere creeps into.The utility model is simple in structure, with low cost, and result of use is good.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of semicircular flanges sleeve of the present utility model;
Accompanying drawing 3 is the top view of accompanying drawing 2;
Accompanying drawing 4-6 is use procedure schematic diagram of the present utility model.
The specific embodiment
Embodiment of the present utility model: the structure of mining screw thread type polished rod drilling rod connection guiding device as shown in Figure 1, comprise sleeve 1, sleeve 1 be two split type semicircular flanges sleeve 2(as shown in Figure 2), in the both sides of each semicircular flanges sleeve 2, be equipped with the stator 3 being connected as a single entity with it, on each stator 3, be provided with two installing hole 4(as shown in Figure 3), semicircular flanges sleeve 2 connects to form sleeve 1 by installing hole 4.
During concrete use, when being drilled in lithosphere as drilling rod A, as shown in Figure 4, when the coaxiality deviation of drilling rod A and drilling rod B is excessive; First, as shown in Figure 5, two paired semicircular flanges sleeves 2 are placed in to the internal and external threads junction of drilling rod A and drilling rod B; Then adopt successively six common rib screws through corresponding installing hole 4, and with six rib nut screwing clampings, the axiality of drilling rod A and drilling rod B has met connection request under the effect of external force, as shown in Figure 6; Last starter motor, along with the rotation propelling of unit head, under guide effect of the present utility model, drilling rod A is connected smoothly with drilling rod B.
