Background technology
Along with the construction energetically of China's infrastructure such as speedway, train, high ferro in recent years, rotary drilling rig obtains very fast development and applies widely.Conventional rotary drilling rig is in work progress, because drilling pipe stack shell is elongated, there is slag dumping difficult problem, especially in clay, mud or boulder bed work progress because clay or mud are bonded on barrel, make drilling pipe especially difficult when slag dumping, even often there is the time that the drilling pipe slag dumping time creeps into underground activities than drilling pipe also long, cause efficiency of construction low.For solving the problems of the technologies described above, someone invents a kind of opposite opened rotary drill tools, is made up of opposite opened brill top and opposite opened drilling pipe, slag dumping is convenient, but this drilling pipe is operationally, soil layer unexpected thinning dredge or the too fast situation of churning driven rotating speed under, due to the effect of centrifugal force, barrel opens suddenly, make to revolve and dig radius change greatly, the quality of digging operation is revolved in impact, even causes landslide, make to revolve and dig operation and cannot proceed, have a strong impact on production operation.
Summary of the invention
For above-mentioned background technology Problems existing, the utility model provides a kind of opposite opened to lock rotary drill tools, and slag dumping is convenient, the slag dumping time is short, revolving in the process of digging the situation that there will not be barrel to open suddenly, thus avoiding the phenomenon occurring landslide, increasing work efficiency.
To achieve these goals, a kind of opposite opened locking of the utility model rotary drill tools, comprise opposite opened drilling pipe, opposite opened bores top, bearing pin block, bearing pin and square toes connecting box, described opposite opened bores top and is fixed on above opposite opened drilling pipe, described bearing pin block is fixed on opposite opened and bores top, top, described square toes connecting box is fixed on above bearing pin block, described bearing pin block both sides respectively correspondence are provided with two pin sleeves, described bearing pin block offers the through hole of the pin sleeve being communicated with bearing pin block both sides, pin sleeve and bearing pin block link together through the through hole on bearing pin block by described bearing pin, described opposite opened bores top solder on pin sleeve, also comprise locking device, described bearing pin and pin sleeve are provided with the matching used keeper with locking device, described locking device inserts keeper.
Preferably, locking device comprises check lock lever and is located at the locking groove of keeper inwall, described check lock lever upper end is cylindrical, end profile is provided with and the projection of locking fit depressions, described locking groove is made up of horizontal groove and perpendicular groove, and horizontal, vertical groove communicates, described perpendicular groove upper end is located at keeper open top and is flushed.
Preferably, locking device is locking pin.
Preferably, locking device comprises locking nut and is located at the locking screw matched with locking nut in keeper.
Preferably, locking device and keeper are provided with four groups altogether.
Further, also comprise wear-resistant block, gusset and bucket tooth, described wear-resistant block is symmetricly set in opposite opened drilling pipe side, and described gusset is symmetricly set in opposite opened drilling pipe bottom, and described bucket tooth is fixed on gusset bottom.
Compared with prior art, the utility model is by guide, bearing pin block and bearing pin, opposite opened drilling pipe is connected, locking device is inserted keeper, barrel cannot freely be opened, when carrying out digging operation, even if soil layer unexpected thinning dredge or the too fast situation of churning driven rotating speed under, barrel also can not open suddenly in the effect of centrifugal force, avoids the generation of landslide phenomenon.When drilling tool proposes ground, can locking device be extracted, open drilling pipe, thus carry out slag dumping very easily, greatly improve efficiency of construction.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of opposite opened locking rotary drill tools, comprise opposite opened drilling pipe 1, opposite opened bores top 2, bearing pin block 3, bearing pin 5 and square toes connecting box 9, described opposite opened bores top 2 and is fixed on above opposite opened drilling pipe 1, described bearing pin block 3 is fixed on opposite opened and bores above top 2, described square toes connecting box 9 is fixed on above bearing pin block 3, described square toes connecting box 9 top jointed rod, drilling rod connects the dynamical system of drilling tool, described bearing pin block 3 both sides respectively correspondence are provided with two pin sleeves 4, described bearing pin block 3 offers the through hole of the pin sleeve 4 being communicated with bearing pin block 3 both sides, pin sleeve 4 and bearing pin block 3 link together through the through hole on bearing pin block 3 by described bearing pin 5, described opposite opened bores top 2 and is welded on pin sleeve 4, also comprise locking device 10, described bearing pin 5 is provided with the matching used keeper 11 with locking device 10 with pin sleeve 4, described locking device 10 inserts keeper 11.Here locking device 10, plays fixing and locking to bearing pin 5 and pin sleeve 4, and opposite opened drilling pipe 1 operationally cannot freely be rotated.
As shown in Figure 3 and Figure 4, as first preferred embodiment of the utility model to technique scheme, described locking device 10 comprises check lock lever 10-1 and is located at the locking groove of keeper 11 inwall, described check lock lever 11-1 upper end is cylindrical, end profile is provided with and the protruding 10-2 locking fit depressions, described locking groove is made up of horizontal groove 11-3 and perpendicular groove 11-2, and horizontal, vertical groove 11-3,11-2 communicate, and described perpendicular groove 11-2 upper end is located at keeper 11 open top and is flushed.When needing locking, the protruding 10-2 of check lock lever 10-1 is aimed at the perpendicular groove 11-2 of keeper 11 inwall, and along perpendicular groove 11-2 slide downward, slide into not slidable position, now this protruding 10-2 is in the junction of perpendicular groove 11-2 and horizontal groove 11-3, rotation lock bar 10-1, and protruding 10-2 is slided along horizontal groove 11-3, thus avoid perpendicular groove 11-2, reach the effect of locking.This preferred embodiment structure is simple, is easy to manufacture, and cost is low, and locking effect is good.
As second preferred embodiment of the utility model to technique scheme, described locking device 10 is locking pin, and locking effect is better.
