Abstract
The utility model relates to a dual-wall drill rod for the anti-circulation drilling of a pneumatic hidden-hole hammer. The utility model which is matched with national existing equipment is designed by a premise that a general exploration team can complete the processing of the drilling tool. The drilling tool is a special novel dual-wall drilling tool for the anti-circulation drilling of a pneumatic hidden-hole hammer drilling or a gas-lift type anti-circulation drilling, composed of a lifting type dual-channel gas tap, an assembly type double-wall drill rod, and a bilateral opening commutation split-flow joint. The drilling tool has the advantages of good detachability, simple structure, high strength, good sealability, easy manufacture, and low cost.
Description
The utility model belongs to the geological exploration techniques field, is specifically to be used for carrying out the anti-pneumatic down-hole hammer that circulates of double-wall pipe to get that landwaste creeps into or the special drilling tool of gaslift reverse circulation drilling.
Carrying out the anti-pneumatic down-hole hammer that circulates of double-wall pipe at present abroad, to get that landwaste creeps into all be to adopt unit head or rig.Use wider TH-50-TH-100 type Series Hydraulic unit head rig as the production of the plain blue company of U.S.'s English lattice, the supporting double-wall drill pipe of this rig all is to adopt the inner and outer pipes welding fixing, integral body processes, difficulty of processing is higher, the reparation of can't disintegrating, the binary channels air water tap that it is used, be that hydraulic power head with this rig fits together, and a whole set of drilling tool comprises binary channels air water tap, double-wall drill pipe, commutation tap and down-the-hole hammer all are to drive at drill power head to do up and down and gyration.And the employed rig of domestic each exploration battle line, mostly based on the vertical shaft type hydraulic feed drill, homemade vertical shaft type hydraulic feed drill commonly used is representative with TK series and XY series rig.
The purpose of this utility model will be designed with homemade vertical shaft type hydraulic feed drill supporting exactly, and makes the complexity of its processing and manufacturing adapt to the novel drilling tool of the condition of China geological prospecting part.
Accompanying drawing 1 is a structural representation of the present utility model.
The utility model as shown in Figure 1 by gooseneck 1, carry parts such as drawing formula binary channels air water tap 2, gas inlet rubber tube 3, double-wall drill pipe 4, rig 5, orifice sealing device 6, commutation tap 7, down-hole hammer 8 and form. Carry and draw formula binary channels air water tap 2 and be installed on the upper of this cover drilling tool Section, on connect gooseneck 1, under connect double-wall drill pipe 4, the lower end of double-wall drill pipe 4 connects tap 7 and pneumatic down-hole hammer 8 by special screw thread, its top is passed the vertical shaft through hole of rig 5 and oil pressure chuck and is connected with the lower end connector of air water tap 2, air compressor machine is sent into the sidepiece air admission hole of binary channels air water tap 2 to compressed air by high pressure admission sebific duct 3 and then through the annular gap of the ectonexine pipe of double-wall drill pipe 4, enter again the cylinder of down-hole hammer 8 through the symmetrical arc-shaped sections passage in the both sides of bottom commutation tap 7, driven plunger is impacted up and down work done, makes drill bit produce the effect of the assorted stone of efficiency crushing. The waste gas that down-hole hammer drill bit steam vent is discharged, carrying underground water and the landwaste that is broken in the hole, annular gap through between down-hole hammer and hole wall enters the inner tube centre bore of double-wall drill pipe 4 through commutation tap 7, on the internal layer centre bore of air water tap 2, return gooseneck 1, deslagging sebific duct through connecting is with it discharged the face of land again, sends the landwaste gathering-device of (gas, liquid, solid body) separation function that has three-phase to. So far namely finish one and instead follow the anti-cyclic process that pneumatic down-hole hammer creeps into. So repeatedly constantly carry out, can realize that high-speed and high-efficiency creeps into.
The utility model compares the main distinction with external like product and advantage is: formula binary channels air water tap is drawn in carrying that 1. the utility model is designed, except sending into compressed air to double-wall drill pipe inner and outer pipes annular gap by it, and the air that returns from the shaft bottom that bottom commutation tap imports, landwaste and phreatic mixed flow are on tube hub returns in drilling rod, again by air water tap central tube and gooseneck, scum pipe returns out outside the ground, can also mention and put down a complete set of drilling tool by the bale handle of air water tap, external air water tap then is to fit together with drill power head, and promotes and put down drilling tool by unit head.2. double-wall drill pipe of the present utility model is a fabricated construction, and dismounting is extremely convenient, the two-tube usefulness of Guan Kezuo in packing into, if pipe can be made single tube usefulness in extracting out, thus have the dual-purpose usefulness of a pipe, and handling ease, low cost of manufacture.And external double-wall drill pipe commonly used mostly is inner and outer pipes welding monolithic construction together, and domestic general exploration crew even machine factory of general province company do not possess its processing conditions, and the manufacturing cost height.3. commutation tap main feature of the present utility model is big latus rectum, bilateral mouth formula structure, and is simple in structure, divides flow resistance little, processing and manufacturing easily.External commutation tap complex structure commonly used is the porous type runner, and takes into account the outer shroud sealing function, makes relatively difficulty, therefore, the utility model is reasonable in design, and is simple in structure, and effect is big, good seal, processing easily, low cost of manufacture has remarkable economic efficiency.
Claims (1)
1, counter the following of a kind of pneumatic down-hole hammer crept into double-wall drill pipe, it by gooseneck, carry draw formula binary channels air water tap, double-wall drill pipe, rig, aperture sealer, commutation tap, the down-the-hole hammer is formed, it is characterized in that:
A, double-wall drill pipe adopt inside and outside double pipe structure, and certain interval is still arranged between the pipe,
The lower end of b, double-wall drill pipe connects tap and pneumatic down-hole hammer by special screw thread, and the upper end is passed the vertical shaft through hole of rig and oil pressure chuck and connected with the following end joint of air water tap.
