Description
Technical field
The present invention relates to a kind of geological drilling equipment, specifically a kind of double-walled axle rock core drilling machine unit head.
Background technology
In the seabottom geology exploration, gas hydrates are surveyed, the exploration of seabed crustal stability property, and the seabed earth's crust changes, and aspects such as seabed mine locating and geologic climate research all need off-shore boring's technology, and the sea bed churn is widely used in off-shore boring.In off-shore boring, adopt usually drilling equipment is placed on the sea bed at present, the operator then carries out Long-distance Control aboard ship.Therefore in off-shore boring, except the requirement that will reach the peer-level land rig, also high requirement is proposed for the automaticity of rig, Long-distance Control performance, sealing performance, reliability etc.
But existing domestic core-drill(ing) machine automaticity is generally not high, and is stronger to artificial back work dependence, causes operating efficiency lower.Also there is following problem in the rock core drilling machine unit head of domestic off-shore boring:
1. probing is not high with the coring automaticity, uses wire line coring need let openings earlier, thus the difficulty increase that Long-distance Control and automation is bored dig.
2. when the traditional power head is got core, need be with water tap unloading and removing on unit head or the drilling tool, operation is many, and service working time is long.
3. the waterproof sealing performance is bad, and it is perishable to work under the hyperbaric environment under water.
Summary of the invention
The objective of the invention is for the deficiency that solves above-mentioned prior art provides a kind of compact conformation, reliable operation, the double-walled axle rock core drilling machine unit head of good airproof performance can be realized creeping into and the wire line coring operation under the situation of openings need not letting; Need not the unloading water tap simultaneously, in the whole drilling process flushing liquor can be provided at any time as required, accomplish at the bottom of the flushing hole; Carry rock dust, cools reamer head, lubricated drilling tool; The protection hole wall, press on control ground, operations such as protection rock ore deposit core.
To achieve these goals; The technical scheme that the present invention taked is: a kind of double-walled axle rock core drilling machine unit head is provided; Comprise outer case, actuating unit, transmission system, axle and sealing unit; Described outer case is made up of casing assembly and upper box lid, and the casing assembly is connected by the alignment pin location and with screw with upper box lid; Actuating unit is hydraulic motor or motor; Transmission system is made up of driving gear shaft and driven gear; Described axle is the double-walled axle; Constitute by pipe in axle outer tube and the axle; Swivel sub and the weldering of axle outer tube are one; When creeping into flushing liquor outside water tap, axle in pipe through-hole and the double-walled axle pipe pass through with annular space between the axle outer tube, creep into that sampler is stored in the interior tube chamber of axle when getting core; The axle outer tube is connected through spline with driven gear, is connected by rolling bearing between axle outer tube, driving gear shaft and casing assembly, the upper box lid, and driving gear shaft is reserved with axis hole and is used to be connected hydraulic motor or motor with keyway; The axle outer tube is threaded on the axle joint through axle joint jointed rod; Described sealing unit has movable sealing and static seal, is made up of between center roller and the casing axle upper end cover, axle bottom end cover and gland and implements movable sealing, has used the static seal sealing between each parts.
Actuating unit of the present invention is hydraulic motor or motor, can select hydraulic motor or motor as requested for use, when unit head is used for rock-core borer probing under water, then uses the motor of hydraulic motor or waterproof.
Have equally distributed six flushing liquor through holes between two groups of dynamic seal rings that two gland center rollers that the axle outer tube top of double-walled axle of the present invention is adjacent at the axle upper end cover and casing form; The middle part of axle outer tube is provided with provides gear-driven spline, between axle outer tube and the axle joint with being threaded.
Pipe directly upwards is welded with three iron blocks of even distribution in the axle of double-walled axle of the present invention in its underpart, and axle outer tube and axle joint position and fix through pipe in the said three iron block center rollers.
The upper end of described axle outer tube is equipped with the axle upper end cover, and the lower end is equipped with the axle bottom end cover, has a water tap water inlet on the axle upper end cover, and aperture place's swivel sub and the weldering of axle outer tube are one.The design of the integrated structure for water tap of the height of this uniqueness, when unit head was connected with water tap, unit head need let the openings This move when having avoided wire line coring, has improved operating efficiency; And need not the unloading water tap when getting core, creep into overall process and can carry flushing liquor as required at any time, accomplish at the bottom of the flushing hole; Carry rock dust, cools reamer head, lubricated drilling tool; The protection hole wall, press on control ground, operations such as protection rock ore deposit core.
Implementing movable sealing between center roller of the present invention and the casing is between two glands that the axle upper end cover is adjacent, to form two groups of ring recess; Also form two groups of ring recess between two glands that the axle bottom end cover is adjacent, realize implementing movable sealing between center roller and the casing through dynamic seal ring is installed in upper and lower two groups of ring recess.
Used the static seal sealing between casing assembly of the present invention, upper box lid, upper end cover, axle upper end cover, the axle bottom end cover.The static seal of using between the described parts is fluid sealant or O RunddichtringO.The sealing of use static seal guarantees that casing does not have extraneous seawater and gets at these bonding surface places.
When unit head of the present invention uses and double-wall drill pipe be used; Moment of torsion and the axial compression transmitted when utilization is crept into are carried out fractured rock; Simultaneously, the movable sealing mode that when creeping at a high speed, adopts has guaranteed that unit head can be suitable for carrying out operation in the hyperbaric environment under water.
A kind of double-walled axle of the present invention rock core drilling machine unit head compared with prior art has following advantage:
1, power head structure compact of the present invention, the design of double-walled axle makes sampler can in axle, manage storage; Solved in traditional wire line coring course of work; Unit head needs laterally to move or rig is whole moves the problem of openings that lets, thereby helps the Long-distance Control and control automatically of rock-core borer under water, has improved drilling efficiency; Practice thrift the time, reduced cost.
2, unit head of the present invention is an one with swivel sub and the weldering of axle outer tube, constitutes highly integrated structure for water tap, and is simple in structure; Improved the reliability and maintainability of work, and flushing liquor is to carry through the through hole that is uniformly distributed with on the axle outer tube circumferencial direction and through the annular space between double-walled axle inner and outer pipes, and this design has realized the function of traditional water tap; Need not the unloading water tap when getting core, in the whole drilling process flushing liquor can be provided at any time as required, accomplish at the bottom of the flushing hole; Carry rock dust, cools reamer head, lubricated drilling tool; The protection hole wall, press on control ground, operations such as protection rock ore deposit core.
3, unit head design of Sealing Structure of the present invention is reasonable, and the waterproof sealing performance is good, and long service life is applicable to rock-core borer under water, also can be applicable to the land core drilling.
