Description
Technical field
The utility model relates to a kind of clamping booster, is that a kind of wire line coring drilling rod is used the aperture clamping device, belongs to mechanical core drilling outfit field.
Background technology
A kind of aperture clamper commonly used of wire line coring probing at present is the deadweight type clamper, has characteristics simple in structure, easy for installation, particularly when hole depth; Because the effect of drill string weight, grip is obvious, and this kind clamper structure is like Fig. 3, shown in 4; Slips moves to the center under ramp effect, the chucking drilling rod, and drilling tool is heavy more; Frictional force between drilling rod and the slips is big more, and this power is ordered about slips and moved down apart from big more, and it is also big more then to add the power of holding to the center.But this clamper is in boring when the initial stage, hole depth was more shallow; Because drilling tool weight is lighter, the frictional force between drilling rod and the slips is little, as making of this clamper by pincers unloading drilling rod; Owing to do not tighten; Can't turn on drilling rod rapidly, simultaneously drilling rod rotates in dovetail slip and by hard slips injured surface, thereby has a strong impact on drilling life of drill pipe.
The utility model content
The utility model is a kind of aperture hydraulic pressure clamping booster that provides for the deficiency that overcomes prior art, has solved hole depth when more shallow, because drilling tool weight is lighter, adds the power of a holding difficult problem less than normal, has both guaranteed clamping safety, can satisfy the unloading requirement again.
The technical scheme that the utility model adopts:
A kind of aperture hydraulic pressure clamping booster, it comprises hollow clamping body, clamping body cavity is provided with slip spider; Be provided with slips in the slip spider, slips and slip spider fitting face are lozenges, and lozenges is provided with rolling element; Respectively be provided with pin-and-hole about the clamping body, be provided with bearing pin in the pin-and-hole, the bearing pin two ends are positioned at the cramping body outside and all are hinged with connecting rod; Be provided with hydraulic cylinder between the bottom of homonymy connecting rod before and after the clamping body; Hydraulic cylinder comprises cylinder sleeve, piston and piston rod, and an end cylinder sleeve of hydraulic cylinder all is connected through pin with connecting rod with connecting rod, other end piston rod, and cylinder sleeve inner carrier one side is provided with spring; The cylinder body of piston opposite side is provided with oil-in, and the top of connecting rod is connected with described slips.
The top of above-mentioned connecting rod is connected with slips through latch.
The technique effect that the utility model is obtained:
1, the utility model is simple in structure, and easy installation and removal is with low cost;
2, use this device, can solve deadweight clamper hole when shallow,, add the power of a holding difficult problem less than normal, both guaranteed clamping safety, can satisfy the unloading requirement again because drilling tool weight is lighter.

The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further explanation.
Referring to Fig. 1-4, a kind of aperture hydraulic pressure clamping booster, it comprises hollow clamping body 1; Clamping body cavity is provided with slip spider 2, is provided with slips 4 in the slip spider, and slips and slip spider fitting face are lozenges; Lozenges is provided with rolling element 3, respectively is provided with pin-and-hole about the clamping body, is provided with bearing pin 7 in the pin-and-hole; The bearing pin two ends are positioned at the cramping body outside and all are hinged with connecting rod 6, are provided with hydraulic cylinder between the bottom of homonymy connecting rod before and after the clamping body, and hydraulic cylinder comprises cylinder sleeve 10, piston 12 and piston rod 8; One end cylinder sleeve of hydraulic cylinder all is connected through pin with connecting rod with connecting rod, other end piston rod; Cylinder sleeve inner carrier one side is provided with spring 9, and the cylinder body of piston opposite side is provided with oil-in 11, and the top of connecting rod is connected with described slips.The top of described connecting rod is connected with slips through latch 5, and latch extends in both sides, clamper front and back.
The utility model is the clamping booster of a kind of mechanical type deadweight type aperture clamper, is the linkage of a cover hydraulic control, and the linkage of a cover hydraulic control is installed on two surveys before and after the deadweight type clamper; Hydraulic cylinder adopts spring to tighten up, and the open mode of hydraulic pressure is behind the logical pressure oil of hydraulic cylinder; Under the pressure oil effect, piston rod and cylinder sleeve oppositely move, and drive latch through linkage and turn an angle; Compress slips, force it to move down, under the effect of slips voussoir along clamper; Slips moves to the center, can more effectively clamp drilling rod in the centre bore.This system piston rod and cylinder sleeve oppositely move; Left and right sides slips is stressed identical; Under Machining of Connecting Rod and installation accuracy assurance, make that left and right sides slips is stressed and displacement is even, more can effectively clamp drilling rod; Increase and to add the power of holding, it is in light weight and cause tightening the problem of drilling rod better to solve shallow bore hole stage drilling tool.This structure is easy to existing machinery formula deadweight aperture clamper is retrofited; Only need will have now about the clamper opsition dependent requirement of aperture respectively to bore a hole, hydraulic clamping device is installed on it to get final product, when boring is dark; As do not need the hydraulic pressure servicing unit; Need only take apart and have strong market potential, whole device can be taken down, and clamper can use by original structure.The forward and reverse active force that adds the power of holding all imposes on latch, and the power utilization rate is high.When the off-load of system pressure oil, under spring action, the oil cylinder retraction drives latch through connecting rod and opens, and at this moment, clamper can use by Purely mechanical, and can be easy to propose slips, makes things convenient for drilling tool lifting, transfers.This installs simple installation, and is easy to maintenance.
The protection domain of the utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from the scope and the spirit of the utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, then the intention of the utility model also comprises these changes and is out of shape interior.
