Translational power head of all-hydraulic core drilling machine
Technical field
The utility model relates to the exploration and development technical equipment of industries such as a kind of geology, coal, metallurgy, coloured, nuclear industry to mineral resources, particularly a kind of translational power head of all-hydraulic core drilling machine that is used for SOLID MINERAL RESOURCES exploration and development coring.
Background technology
Major technique equipment---the rig of mineral resources exploration exploitation is experiencing import, imitated, several stages such as research and development manufacturing voluntarily.Now, China's geological prospecting every profession and trade is still also being used traditional rock-core borer of initial stage seventies design in large quantities, the all-hydraulic core drilling rig that grew up in recent years, because of its boring tower collapsible, available oil cylinder rises and falls, with engine, main winch, the rope winch, slush pump, electric, hydraulic pressure and dig the system system, the first-class integral type of power is arranged on the platform, full hydraulic drive, steel crawler travel, the power head length feeds stroke, the big latus rectum of main shaft, all-hydraulic controlling, rate of penetration is fast, high efficiency, the resettlement place is quick, aligns the aperture convenience and can make a call to 45 ° of-90 ° of advantages such as scope inclined hole, and the gesture that replaces traditional rock-core borer is arranged greatly.But the dynamic head main spindle of the type rig or can not break away from drill center, otherwise upset breaks away from drill center, efficiency of construction is low in the time of can not leaving the center, aperture, and operation inconvenience can not be satisfied the requirement of drilling operation operation; When overturning, convertible unit head need very big external force effect to overturn, at mast vertical drilling state, need 2-3 people firmly can realize upset simultaneously, upset is difficult during inclined hole in making a call to 45 ° of-90 ° of scopes, almost can not lean on artificial upset near 45 ° of-60 ° of scopes.So the unit head of overturn structure can not satisfy the center requirement of dynamic head main spindle skew drilling orifice.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of translational power head of all-hydraulic core drilling machine convenient to operation.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of translational power head of all-hydraulic core drilling machine, comprise main spindle box assembly and slide, be characterized in: slide is provided with lateral slide rail, the main spindle box assembly is contained on the lateral slide rail, is provided with the driving mechanism that the main shaft casing laterally moves at the sidepiece of lateral slide rail.
The technical problems to be solved in the utility model can also come by the following technical programs to realize that further described driving mechanism is provided with the travelling gear of fluid motor-driven that the main spindle box assembly is provided with the driving rack of the horizontally set that cooperates with travelling gear.
The technical problems to be solved in the utility model can also come to realize that further described driving rack is provided with two, is arranged side by side between main shaft casing and slide by the following technical programs.
The technical problems to be solved in the utility model can also be come by the following technical programs further to realize, be provided with main shaft casing translation positive stop on slide.
The technical problems to be solved in the utility model can also be come by the following technical programs further to realize, is provided with the working position locking device between main shaft casing and the slide.
The utility model compared with prior art, motor, gear, tooth bar transmission are adopted in the unit head translation, realize that reliably the dynamic head main spindle center can depart from drill center, replace artificial turning operation with hydraulic drive control, greatly alleviate labour intensity, improved the probing operating efficiency effectively; Unit head translation hydraulic control and operation, compact conformation, reliable operation, convenient to operation.

The specific embodiment
A kind of translational power head of all-hydraulic core drilling machine, comprise main spindle box assembly 3 and slide 5, slide 5 is provided with lateral slide rail 7, and main spindle box assembly 3 is contained on the lateral slide rail 7, is provided with the driving mechanism 8 that the main shaft casing laterally moves at the sidepiece of lateral slide rail 7.
Described driving mechanism 8 is provided with the travelling gear 4 of fluid motor-driven, and the main spindle box assembly is provided with the driving rack 6 of the horizontally set that cooperates with travelling gear 4.Described driving rack 6 is provided with two, is arranged side by side between main shaft casing 3 and slide 5.On slide 5, be provided with main shaft casing translation positive stop 2.Be provided with working position locking device 1 between main shaft casing 3 and the slide 5.Guarantee the locking after unit head translation left arrives limiting block iron.
The main shaft casing adopts steel work group welding piece, blank to carry out mechanical roughing, semifinishing, fine finishining after heat treatment normalizing eliminates stress.Carry out hard surfacing after the rail plate assembly fine finishining of symmetric arrangement, match grinding guide pass, match grinding pressing plate guide pass, assembling and setting gap reach slip freely at 0.05-0.15.Double rack adopts equipped group point, should fluent, nothing interference when the unit head translation.Translation transmission and driven unit are taken turns symmetric arrangement, are installed in the slide termination by hydraulic motor, double base bearing support, bidentate, driving moment are provided for the translation of unit head.At two extreme position combo point positive stops of unit head left and right sides translation, moving to left puts in place afterwards compresses locked with two hold-down bolt balances.
Unit head translation stroke should guarantee when main shaft departs from the aperture cord coring drill in the safe space up and down freely, accurately realize the requirement of coring process.Former operating position is returned in the unit head translation, and spindle centerline should be able to overlap with drill center, and its error should be less than 1mm, and when creeping into duty, and unit head must be reliably, locked in the operating position effectively.
