Description
Technical field
The utility model belongs to oil, natural gas drilling equipment technical field.
Background technology
At present, the aluminium drill pipe that oil and exploration industry use is buy from Russia, the U.S., Japan and other countries substantially, the elastic conjunction of external aluminium drill pipe and steel joint is adopt hot charge practice substantially, heat by steel joint, its size heat is risen, then be equipped with aluminium drill pipe, after cooling, realize elastic conjunction.Because steel joint needs to be heated to about 400 DEG C, and the annealing temperature of aluminum alloy materials only has 250 DEG C, the annealing phenomena of aluminium drill pipe is easily there is in this assembly method in assembling process, aluminium drill pipe is once annealing, just can not re-use, whole drilling rod and the steel joint assembled all will be scrapped, and for preventing aluminium drill pipe from annealing, need supporting aluminium drill pipe water cooling equipment, the circulatory system and temperature control system.A large amount of corollary equipments not only adds cost and takes up an area space, operationally also very loaded down with trivial details.Even but employ water cooling equipment, be also only the body of rod cooling aluminium drill pipe, the screw thread of elastic conjunction position is difficult to be cooled in time, and then has influence on the use of product.
Summary of the invention
The purpose of this utility model is: provide a kind of aluminium drill pipe and steel junction to close assembling device, it carries out elastic conjunction by cold and hot method of carrying out simultaneously, reduces the heating-up temperature of steel joint, and does not need aluminium drill pipe cooling device and the circulatory system.
The technical solution of the utility model is: be made up of aluminium drill pipe cooling device, steel joint firing equipment and support precession equipment.
In cooling device, seal washer is coated on two surfaces of cooling chamber inner chamber respectively, prevents liquid nitrogen from overflowing, and thermometric galvanic couple is arranged on two places up and down of cooling chamber respectively, digital display is connected with thermometric galvanic couple, and the liquid nitrogen gas bomb air inlet of insulating tube with cooling chamber end face is connected.When cooling aluminium drill pipe, being controlled the flow of liquid nitrogen by the wearing flow valve of liquid nitrogen gas bomb, after reaching chilling temperature, reducing liquid nitrogen flow, making cooling chamber remain on design temperature.In the body water-cooling equipment of firing equipment, cyclic control system, stove, temperature measuring equipment and body of heater are integrated on firing equipment, and feedback temperature control display system is integrated on console.Support bracket fastened pressure strip two bearing pins and matrix are fixed, and the threaded rod on rotary pressure plate carrys out clamping work pieces.Mobile adjustable support adjusts upper end locating piece height by regulating the nut on matrix four studs, and the positioning guide rail of mobile matrix lower end can adjust the right position of upper end locating piece.After aluminium drill pipe and steel joint reach temperature retention time, steel joint is released from heating furnace, transfer on mobile adjustable support, rapidly steel joint is docked with aluminium drill pipe, start torsion motor, after steel joint and aluminium drill pipe screw and cool, reversion torsion motor, is separated steel joint with torsion motor profiling threaded post.
The beneficial effects of the utility model are: adopt cold and hot assembly method of simultaneously carrying out, not only reduce the heating-up temperature of steel joint, eliminate the cooling device of aluminium drill pipe, also fundamentally avoiding the annealing risk of aluminium drill pipe, while reducing costs, improve yield rate, decrease and take up an area space and operating procedure.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Fig. 1-1,1-2,2-1,2-2,1 be bearing pin, 2 are threaded rods, 3 are pressing plates, 4 are locating pieces, 5 is swingles, 6 are the rest body, 7 that are fixed and clamped are screw thread columns, 8 are rollers, 9 are lifting platforms, 10 are nuts, 11 are mobile adjustable support matrixes, 12 are position-limited wheels, 13 is limit guide rail.
As shown in Figure 3,14 are aluminium drill pipes, 15 are cooling chambers, 16 thermometric galvanic couples, 17 are power frequency heating furnaces, 18 are torsion motors.
As shown in Figure 6,19 are steel joints, 20 are profiling threaded post, 21 are drive links, 22 are shaft couplings, 23 are fastening bolts, 24 are keys, 25 is traversing carriages.
By conventionally by magnitude of interference steel joint being heated to higher temperature generation, instead by cooling aluminium drill pipe and producing the magnitude of interference by being heated to lower temperature to steel joint.Aluminium drill pipe is cooled to subzero less than 100 DEG C; steel joint is heated to 200 DEG C; like this when elastic conjunction; steel joint only has 200 DEG C; and aluminium drill pipe is subzero less than 100 DEG C; do not reach the annealing temperature of aluminium alloy far away, effectively achieve the protection of butt joint position aluminium drill pipe screw thread.
Cooling device is made up of cooling chamber, thermometric galvanic couple, digital display, liquid nitrogen gas bomb, seal washer, insulating tube.
Firing equipment is made up of temperature measuring equipment, feedback temperature control display system in Medium Frequency Induction Heating Furnace, body water-cooling equipment, cyclic control system, stove.
Support precession equipment to be made up of the support that is fixed and clamped, movable supporting frame, mobile adjustable support, torsion motor.
In cooling device, seal washer is coated on two surfaces of cooling chamber inner chamber respectively, prevents liquid nitrogen from overflowing, and two places being up and down arranged on cooling chamber differentiated by thermometric galvanic couple, digital display is connected with thermometric galvanic couple, and the liquid nitrogen gas bomb air inlet of insulating tube with cooling chamber end face is connected.During cooling aluminium drill pipe, controlled the flow of liquid nitrogen by the wearing flow valve of liquid nitrogen gas bomb, after reaching chilling temperature, reduce liquid nitrogen flow, make cooling chamber remain on design temperature.In the body water-cooling equipment of firing equipment, cyclic control system, stove, temperature measuring equipment and body of heater are integrated on firing equipment, and feedback temperature control display system is integrated on console.
Support bracket fastened pressure strip two bearing pins and matrix are fixed, and the threaded rod on rotary pressure plate carrys out clamping work pieces.Mobile adjustable support adjusts upper end locating piece height by regulating the nut on matrix four studs, and the positioning guide rail of mobile matrix lower end can adjust the right position of upper end locating piece.After aluminium drill pipe and steel joint reach temperature retention time, steel joint is released from heating furnace, transfer on mobile adjustable support, rapidly steel joint is docked with aluminium drill pipe, start torsion motor, after steel joint and aluminium drill pipe screw and cool, reversion torsion motor, is separated steel joint with torsion motor profiling threaded post.
