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, seabed crustal stability exploration, 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 and coring automaticity are not high, use wire line coring need get out of the way the aperture earlier, thereby the difficulty that makes Long-distance Control and automation bore pick increases.
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 provides a kind of compact conformation for solving above-mentioned the deficiencies in the prior art, reliable operation, the double-walled axle rock core drilling machine unit head of good airproof performance; can under the situation that need not get out of the way the aperture, realize creeping into and the wire line coring operation; need not the unloading water tap simultaneously, can provide flushing liquor as required at any time in the whole drilling process, finish at the bottom of the flushing hole; carry rock dust; the cooling drill bit, lubricated drilling tool, protection hole wall; press on control ground, operations such as protection rock ore deposit core.
To achieve these goals, the technical solution used in the present invention 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 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 by 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 shaft coupling by the shaft coupling 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.
The axle outer tube top of double-walled axle of the present invention has equally distributed six flushing liquor through holes between two groups of sealing rings, 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 by pipe in the described 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 structure for water tap design that the height of this uniqueness is integrated, when unit head was connected with water tap, unit head need get out of the way the aperture This move when having avoided wire line coring; 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, finish at the bottom of the flushing hole; carry rock dust; the cooling drill bit, lubricated drilling tool, 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 to form two groups of ring recess between two glands that the axle upper end cover is adjacent, 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 by 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 enters 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 adopts when creeping into has at a high speed 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 of the present invention is simply compact, the design of double-walled axle, make 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 getting out of the way the aperture, thereby helps the Long-distance Control and the control automatically of rock-core borer under water, has improved drilling efficiency, save the time, reduced cost.
