Description
Technical field
The present invention relates to a kind of hole drilling device, especially a kind of hollow downhole motor wire line coring drilling dress of combination
It puts, belongs to drilling equipment technical field.
Background technology
Wire line coring drilling is that assembly in drilling tool is put into special cord drill-rod, after coring is crept into, uses rope
Interior assembly is salvaged a kind of geological prospecting borehole construction method of earth's surface acquisition core by rope fisher, since location of the coring procedure is not required to
Hundreds of or thousands of meters of drilling rods in hole are proposed into earth's surface, therefore greatly improve work efficiency.
The outer assembly of drilling tool used in conventional wire line coring drilling method is formed by connecing cord drill-rod on outer tube, interior assembly
Including inner tube, clamp spring and single action suspension assembly, drilling rod and drill bit is driven to turn round detritus by earth's surface rotary motive power.New hair in recent years
The technology of exhibition is to increase Hydro-efflux Hammer, screw rod rotary motor in interior assembly, using Hydro-efflux Hammer wire line coring drilling method or screw rod
Motor+Hydro-efflux Hammer shaft bottom revolution impact wire line coring drilling method, so as to further improve the working efficiency of coring drilling, but
It is that above two wire line coring drilling apparatus is all using screw motor and Hydro-efflux Hammer as assembly in drilling tool, before coring drilling
Put into outer assembly together, it is another after drilling to salvage earth's surface together, especially during deep well drilling, led to by top rod
The outer diameter of the restriction of bore dia, screw motor and Hydro-efflux Hammer is all necessarily less than drilling rod through-hole diameter, therefore, is turned round by screw rod
The rotary torque and be restricted by the ballistic work that Hydro-efflux Hammer generates that motor generates, cannot expire in major diameter core-drilling construction
Foot requirement.
