Description

A kind of rig

Technical field

The utility model is related to a kind of rig.

Background technology

Rig is geological drilling and engineering construction probing Core equipment, is widely used in engineering investigation, geological prospecting, geology Hazard management, hydrology and water well drilling and engineering construction.All using manually handle, existing rig major defect is existing rig: The high labor intensive of workmen, work under bad environment, construction is strong to the technology dependence of operating personnel；

Wherein drill power head is mainly used in top drive churn provides drilling power, and existing driven by power is vertical machine Direct drive, its shortcoming is: produces larger axial dimension, the flushing liquid injection system of rig is arranged on below unit head, knot Structure is complicated, is easily damaged.

Existing geological prospecting and engineering construction drill the connection of drilling rod all using thread connection, need by high pressure in drilling rod Flushing liquor, so two junctions need sealing very well, be primarily present following shortcoming: the stress that (1) thread connection produces Concentrate the intensity weakening tool joint, tool joint fracture accident often occurs；(2) need in the application using pipe wrench or Free pliers disconnect, on construction ground narrow place or be difficult to the instrument of putting to good use during work high above the ground, disconnect very difficult, using twisting It is high that pipe machinery disconnects equipment cost.

The unit head lifting of existing power head drilling machine adopts slide formula guiding mechanism mostly, and its shortcoming is guide material Require to select special material, need to be heat-treated and machining, need in unit head running to lubricate, guiding trestle matter Amount is heavy, it is quick detachable not allow, and manufacturing cost is high.

Existing power head drilling machine generally is implemented to carry to draw to stacks using its power transmission shaft, and dismantles docking by fork mode Thread connection, and lower for dismounting drilling rod is vertically stood on boring tower or manually takes off placement it is impossible to traction drilling rod is from the surface water Prosposition is put rising or is placed into horizontal level from vertical position decline.For need high-altitude dismounting and need to be by drilling rod horizontal positioned Or the situation from horizontal level lifting, the lifting of drilling rod can only separately be made a trip using independent hoist engine, increased and apply Frock is standby.

Clamper be in drilling process drilling rod or sleeve pipe lift or under fashionable holding drilling rod or sleeve pipe grip Clamping device in aperture or clamping machinery.Existing clamper includes fork, wooden horse clamper, gravity clamper, hydraulic pressure Clamper etc., species is various；Wherein in addition to fork, mostly adopt the work of axial stretching method of clamping, the axial dimension of clamper Greatly, it is clamped drilling rod or the clamping dimension scope of sleeve pipe is little, typically a kind of clamping range of gripper block is less than 10mm (include change clamping fixture block), and can not holding drill pipe and sleeve pipe simultaneously；And wooden horse clamper and gravity clamper etc. Also exist complex operation, holding capability is poor, drilling rod easily glide etc. " run bore " accident the shortcomings of.

Twisting machine is that drilling project makes a trip the important Aided Machine of process mechanism, and existing twisting machine adopts liquid mostly Pressure clamping and oil motor drive rotation mode manufacture, have that axial dimension is big, manufacturing cost is high, operating cost is big, mechanical breakdown The high defect of rate.

The main lifting feed mechanism of existing power head drilling machine specifically includes that the Chain conveyer liter of oil cylinder traction or oil motor Fall feed mechanism, rack pinion lifting feed mechanism etc..The former have feed steady lifting force big the features such as, all-hydraulic Rig is extensively applied, and its shortcoming is to need the support of hydraulic system, and such as the non-hydraulic drill rig possessing hydraulic system needs to apply When hydraulic system set up high cost.The latter is mainly used in the feed of small-power rig, and stationarity is poor, is used mostly manually operated Feed, need to be driven using variable-frequency motor when being fed using motor.
