Detailed description of the invention
Core of the present invention there is provided a kind of pneumaticly beats boomerang point device, reduces the hand labor intensity of beating boomerang point, improves operating efficiency.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on embodiments of the invention, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope of protection of the invention.
Please refer to Fig. 1-Fig. 6, a kind of pneumatic structural representation beating the coupling assembling of boomerang point device that Fig. 1 provides for the embodiment of the present invention; Fig. 2 is the A-A schematic cross-section in Fig. 1; Fig. 3 is the B-B schematic cross-section in Fig. 1; Fig. 4 is the C-C schematic cross-section in Fig. 1; A kind of pneumatic structural representation beating the turning set of boomerang point device that Fig. 5 provides for the embodiment of the present invention; The pneumatic structural representation beating the coupling assembling of boomerang point device of another kind that Fig. 6 provides for the embodiment of the present invention.
Embodiments provide and a kind of pneumaticly beat boomerang point device, comprise pusher leg drill and coupling assembling, wherein, pusher leg drill is generally applied in mine construction field, but before not used for beating boomerang point, the drill steel 3 of pusher leg drill is connected with boomerang point by coupling assembling, utilizes the power of pusher leg drill to carry out beating boomerang point.
Carry out beating boomerang point owing to have employed pusher leg drill, instead of the mode that existing artificial use sledgehammer carries out beating boomerang point, as long as workman's operation pusher leg drill can complete play the operation of boomerang point, therefore, reduce the hand labor intensity of beating boomerang point, and the power of pusher leg drill is unlimited, and dynamics of beating is larger than manpower, so, the degree of depth of beating boomerang point can be increased to about five meters, even darker, the rock harder for material also can be thrown into, thus improves operating efficiency.Because the degree of depth of beating boomerang point adds, so the construction progress of roadway support is accelerated, reach the safety requirements of supporting requirement, reduce the potential safety hazard of roof fall.
In the present invention one specific embodiment, coupling assembling comprises bit shank sleeve 2 and turning set 1, as Figure 1-Figure 5; Bit shank sleeve 2 is socketed on the drill steel 3 of pusher leg drill, and bit shank sleeve 2 and drill steel 3 axial and circumferential are located, and bit shank sleeve 2 can rotate with drill steel 3 and axial reciprocating moves; Turning set 1 is socketed in the outer ring of bit shank sleeve 2, and the inner ring of turning set 1 has positioning step 102, turning set 1 is enclosed within bit shank sleeve 2 outer ring, and abutted with the end of bit shank sleeve 2 is spacing by positioning step 102, then turning set 1 moves with bit shank sleeve 2 and drill steel 3 axial reciprocating, the end of turning set 1 is provided with beats end 101, beat end 101 directly to contact with the end of boomerang point, for beating boomerang point, drill steel 3 is successively through bit shank sleeve 2 and turning set 1, and stretch out outside turning set 1, the inner ring of the partial insertion boomerang point stretched out, plays the effect of location.
The drill steel 3 of pusher leg drill is connected with boomerang point by above-mentioned coupling assembling, the reciprocating motion of drill steel 3 is passed to boomerang point, achieves pneumatic technology of beating boomerang point.During use, first bit shank sleeve 2 is enclosed within drill steel 3, again turning set 1 is enclosed within bit shank sleeve 2, drill steel 3 stretches out outside turning set 1, in the partial insertion boomerang point afterwards drill steel 3 stretched out, achieve pusher leg drill and be connected with the power of boomerang point, normally start according to the working regulation of pusher leg drill afterwards, the position of adjustment boomerang point and angle, carry out beating boomerang point.
Further optimization, the hammering end 101 in the present embodiment is structure as a whole with turning set 1, convenient processing, and certainly, beating end 101 can be also Split type structure with turning set 1.
Locate with the circumference of drill steel 3 to realize bit shank sleeve 2, then the cross sectional shape of drill steel 3 is regular hexagon, and correspondingly, the inner ring cross sectional shape of bit shank sleeve 2 is also regular hexagon, and coincide with the cross sectional shape of drill steel 3, achieves bit shank sleeve 2 rotation together with drill steel 3.Certainly, the cross sectional shape of drill steel 3 and bit shank sleeve 2 can also be other noncircular cross section, such as quadrangle, octagon etc., if can realize both circumferential positioning instant can, be not specifically limited at this.
The present invention one specific embodiment provides another coupling assembling, and as shown in Figure 6, coupling assembling comprises bit shank sleeve 2 and turning set 4, and bit shank sleeve 2 is socketed on drill steel 3, and bit shank sleeve 2 and drill steel 3 axial and circumferential are all located; One end of turning set 4 and the end abutment of bit shank sleeve 2, the other end of turning set 4 has the hammering end 401 for beating boomerang point, and drill steel 3 stretches out turning set 4 and penetrates in boomerang point inner ring.The bit shank sleeve 2 of this coupling assembling is not socketed in turning set 4 inside, but both directly abut, and can realize the power transmission of pusher leg drill equally to boomerang point.
In addition, coupling assembling can also only include bit shank sleeve, one end of bit shank sleeve and drill steel axial location, the other end directly abuts with boomerang point, for beating boomerang point, as long as bit shank sleeve is enough large with the contact area at the sharp position contacted of boomerang, the transmission of power just can be realized.
As optimization, the boomerang point in the present embodiment is hollow steel pipe, and while weight reduction, having higher intensity, also can be solid steel pipe, just arranges trepanning at the position be connected with drill steel 3.
More preferably, the tip of boomerang point is half pointed structures of 45° angle, both ensure that the structural strength that boomerang point is most advanced and sophisticated, and has been convenient to throw in country rock simultaneously.
Utilize pusher leg drill to carry out playing the top layer supporting that the technology of boomerang point can also be applied to unsteady moisture mud stone, be applied to construction of tunnel field and open mine side slope and dam, mine tailing Kuku and road slope protection field.
In this manual, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
