Abstract

The invention discloses the anti-blocking drilling rod of a kind of mine floor anchoring, comprise hollow drill, hollow bushing, be located at the nipple of hollow drill termination, be located at hollow drill external surface, prism-shaped spanner draw-in groove between nose threads joint and tailing screw flight joint, be located at the helical form connecting line between hollow bushing and hollow drill, be located at the water proof slot of hollow bushing afterbody.This equipment not only can be holed to mine floor, can also realize creeping into, clear up, blowdown carries out simultaneously.Its structure is simple, and strong adaptability, easily operates, and blocking-proof result is good, has practicality widely.

Description

The anti-blocking drilling rod of a kind of mine floor anchoring
Technical field
The present invention relates to base plate anchoring device technical field, particularly a kind of mine floor anchoring drilling rod realizing the construction of anti-blocking rapid cleaning.
Background technology
Along with the fast development of China's economic construction, energy demand is very big, and coal resources are difficult to change as the main source of China's energy supply in the future for a long period of time, causes coal industry constantly towards mechanization, automation direction development.The most colliery of China is due to reasons such as coal petrography character, buried depth, geostatic stress, and Floor Heave in Roadway destroys serious, have impact on tunnel use safety, constrains the safety in production of mine, and therefore jacking of floor management task is arduous.
Present stage, China is bolt support for the main means of mine floor Reinforcement.At present, the domestic anchoring device development specially for baseboard of coal mine roadway is little.And the wet method bore mode that typical anchoring device uses now is the hollow drill pipe water under high pressure having fixing water source to provide directly being injected rotation, the mud mixture formed is squeezed out by the gap of drilling rod and coal (rock) layer.There are some technical problems when mine floor carries out operation in this kind of wet method bore mode: first, the mud mixture squeezed out can not be collected with drilling rod splashes, have impact on normal transport and workman's walking in tunnel, floor rocks inundated intenerating exacerbates pucking problem simultaneously; Secondly, traditional bore mode easily causes plug-hole at construction of bottom plates, moves back brill, the work of clear hole is very loaded down with trivial details, had a strong impact on the efficiency of construction of base plate anchoring in drilling process; 3rd, in boring, coal (rock) powder enters tunnel, exacerbates the difficulty of tunnel treating flour dust, and harm workman is healthy.
Therefore, develop a kind of realize safe and simple install, rapid cleaning construction base plate anchoring drilling rod for present stage coal production, there is important use value.
Summary of the invention
The object of the invention is according to prior art Problems existing, provide that a kind of structure is simple, small investment, integrate the anti-blocking drilling rod of mine floor anchoring of boring, clearly hole, dirt eliminating function.
The anti-blocking drilling rod of mine floor anchoring of the present invention, comprise hollow drill, hollow bushing is provided with in described hollow drill, the front end of hollow drill is provided with nose threads joint, rear end is provided with tailing screw flight joint, described hollow bushing is wound with spiral connecting line, and the hand of spiral of connecting line is contrary with drilling rod work rotation direction, and connecting line and hollow drill endoporus form spiral-shaped slits; Hollow bushing afterbody is provided with water proof slot.
Described hollow drill external surface is positioned at nose threads joint and tailing screw flight joint is equipped with spanner draw-in groove; Described spanner draw-in groove is prismatic or square.
Beneficial effect: owing to adopting technique scheme, the present invention not only can carry out efficient drilling to mine floor, can also realize creeping into, clear up, blowdown carries out simultaneously.During drilling rod work, can pressurize to clear water, wash away cleaning by coal (rock) powder of pressurization clear water to boring tip position, and by hollow bushing, termination sewage is extracted out, carry out follow-up focusing on.This equipment effectively ensure that the blocking-proof result of mine floor anchoring drilling rod.Solve traditional bore mode easily causes plug-hole problem at construction of bottom plates, save and move back the very loaded down with trivial details working programme such as brill, clear hole in drilling process, greatly improve the efficiency of construction of base plate anchoring.Its structure is simple, and strong adaptability, easily operates, and has practicality widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is hollow bushing structural representation.
In figure: 1-hollow drill; 2-hollow bushing; 3-spanner draw-in groove; 4-connecting line; 5-nose threads joint; 6-tailing screw flight joint; 7-water proof draw-in groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, one embodiment of the present of invention are further described:
Shown in Fig. 1, Fig. 2, the anti-blocking drilling rod of mine floor anchoring of the present invention, form primarily of hollow drill 1, hollow bushing 2, described hollow bushing 2 is located in hollow drill 1, the front end of hollow drill 1 is provided with nose threads joint 5, rear end is provided with tailing screw flight joint 6, and described hollow drill 1 external surface is positioned at nose threads joint 5 and tailing screw flight joint 6 place is equipped with spanner draw-in groove 3, and spanner draw-in groove 3 is prismatic or square.Described hollow bushing 2 is wound with spiral connecting line 4, and the hand of spiral of connecting line 4 is contrary with drilling rod work rotation direction, and connecting line 4 and hollow drill 1 endoporus form spiral-shaped slits; Hollow bushing 2 afterbody is provided with water proof slot 7.
The course of work: after drilling rod is connected with rig and drill bit, inserts water proof slot 7 by hollow bushing 2, and fastens spanner draw-in groove 3 with spanner and tightened by drilling rod, realizes drilling rod end to end, extension arm.Rig drives drilling rod to rotate by tailing screw flight joint 6, carries out boring work.Simultaneously, pressurization clear water enters drilling rod by the cavity between hollow drill 1 and hollow bushing 2, along with helical form connecting line 4 rotational conveyance between hollow drill 1 and hollow bushing 2 is to drill bit, cleaning boring, helical form connecting line 4 has the effect of well pressurization water guide effect and fixation hollow sleeve pipe 2; Be blowdown channel in hollow bushing 2, in boring cleaning process, by taking out dirty device in rig, by sewage in the hollow bushing 2 of the anti-blocking drilling rod of drill bit suction mine floor anchoring, thus realizing the discharge of sewage.This equipment solves traditional bore mode easily causes plug-hole problem at construction of bottom plates, saves in drilling process, to move back the very loaded down with trivial details working programme such as brill, clear hole, achieves and creeps into, clears up, carries out while blowdown operation.
