The specific embodiment
A kind of device that is used to repair drilling rod 1 comprise base plate 2, tubing storeroom 3, products storage place 4, drill rod rack 5, drilling rod rotor 6, roller support 7, self-propelled dolly 8 and be used for built-up welding drilling rod 1 sleeve part 9 device and be used for the device of built-up welding drilling rod 1 connector portions 10.
Be connected in drilling rod in anodal ("+"), negative pole ("-") is when being connected in welding rod, and the roller support 7 of said drilling rod alives, and is furnished with a copper black lead brush 11 and a soft electric wire 12.
Be used for the sleeve of built-up welding drilling rod 1 and the device of connector portions and be made up of guide rail 13 and automatic resurfacing welding machine 14, automatic resurfacing welding machine 14 comprises power supply 15, the soldering tip 17 that has control panel 16, the mechanism 18 that sends welding rod 19 to, mechanism 20, the mechanism 21 of vibratory horn 17, the device 22 that is used to align bonding wire, the funnel 23 of solder flux 24 and the solder flux feeder that is made up of pipe 25 and funnel 26 of welding rod 19 is installed; At the position down of said drilling rod 1, be provided with from an end and suppress the also solder flux storing apparatus 27 of the form of the plurality of elastic line of flexible fastening on drilling rod 1.
The welding rod 19 of said soldering tip 17 for being arranged in a row at the axis that is parallel to drilling rod 1, so that the spacing of adjustment welding rod and welding rod, and constitute and " summit " deviation from linearity " A " and angular deviation α.The negative pole of said power supply 15 ("-") is connected in welding rod 19.All welding rods that are used for built-up welding tool joint portion are by the first power supply energize, and all welding rods that are used for built-up welding drilling rod sleeve part are by the second source energize.
The walking of welding rod 19 is with to send solder flux 24 to synchronous.
The rotation of drilling rod 1 is to utilize the anchor clamps 28 that are supported in drilling rod 1 inwall to be transmitted by rotor 6.Said device is connected with compressed air source 29 and cools off with 1 discharged air in drilling rod.After built-up welding was accomplished, said device was furnished with the solar heat protection heat-insulating fiber that is used for drilling rod 1 end region temperature adjusting control.In order to cool off drilling rod 1 end and to hold solder flux 24, ring 30 receives the pressure of said end; Do like this, the hollow blank flange that said ring 30 usefulness are threadedly connected on the drilling rod 1 fixes (not shown in the accompanying drawing).
In order to deliver to bonding wire in the built-up welding district, be provided with the mechanism 18 that is used to send to welding rod 19, said mechanism comprise driver with play calibration function send the pinch roller that cylinder compresses bonding wire to reverse.
Aligning bonding wire device 22 comprises the brush of sending to and accepting, and receives and pinch roller, and when bonding wire passed through them, bonding wire was aligned.
The mechanism 20 of installation welding rod 19 can have " summit " deviation from linearity with welding rod 19.In order to realize and " summit " angular deviation that soldering tip 17 is fixed on the installing rack that has axial or spherical annex.
The said device course of work is following:
Drilling rod to be repaired 1 is put in tubing storeroom 3.Utilize 5, drilling rods 1 of drill rod rack to be transferred to the built-up welding station and place on the roller support 7.To carry out: load onto bonding wire; Confirm the position of welding rod 19; The inspection solder flux is sent to; The solder flux injection device is installed; Rotor 6 is installed on drilling rod 1.Said welding rod 19 place with " summit " deviation from linearity 20～30mm and with the mutually antisymmetric horizontal plane of sense of rotation of the drilling rod 1 of 18～26 ° of " summit " angular deviations in.Then, the Oscillation Amplitude of said welding rod 19 and frequency are carried out tuning through vibrating mechanism and are carried out built-up welding trial run or control model.
When repairing drilling rod 1, the moulding of treating bead welding is to accomplish along the bus position of drilling rod 1 at drilling rod 1 vertical section through the arc surfacing machine of the below of the lip-deep solder flux 24 in drilling rod 1 abrading section.("-") is connected in welding rod 19 when negative pole, and anodal ("+") carries out the positive polarity built-up welding when being connected in drilling rod 1.All welding rods 19 that are used for built-up welding tool joint portion are by the first power supply energize, and all welding rods 19 that are used for built-up welding drilling rod sleeve part are by the second source energize.One group of welding rod helps distributing equilibrium to make the impartial fusing of welding rod by the energize of same power supply, promptly balanced consumption.When welding rod 19 is walked along the axis front and back of the drilling rod 1 of rotation, realize vertical section.Select the spacing of 19 of welding rods to equal welding rod 19 in the distance of drilling rod 1 vertical section along the bus walking.Welding rod 19 advance and to send solder flux 24 to synchronous.In overlaying method, in overlaying method, installation copper ring 30 carries out from the end through discharged air in drilling rod with in the end in the drilling rod cooling, and said copper ring 30 also is used for holding solder flux on the surface of drilling rod 1.In order to prevent that the built-up welding district from not cooling off fast and ventilate, before being positioned over the products storage place, the temperature-controlled cabinet of being made by a kind of heat insulation material of asbestos type is installed in the top of each sleeve part and connector portions.
Built-up welding connector portions and sleeve part both can also can separately carry out simultaneously.
The drilling rod of having repaired is transferred to products storage place 4.
With regard to built-up welding, welding rod is a kind of solder wire, for example H
IIThe 30XTCA type, diameter 1.8-2.0mm is through rust cleaning and decontamination, with solvent such as white spirit or the cleaning of A95 type gasoline; φ BT-1 type solder flux, 400 ℃ of temperature lower calcinations 3 hours, perhaps 48-O φ-10 type solder flux; With a kind of cord-like asbestos, diameter 6-8mm.
The wearing and tearing connector portions and the sleeve part that one workpiece junction fraze are reached the drilling rod of 148-150mm carry out built-up welding.In this case, the maximum ga(u)ge of overlay cladding should reach every diameter 16mm and comprise the following process surplus.The width of repair layer is not less than 180mm; The sleeve place is not less than 350mm.Carry out built-up welding with 3 or 4 welding rods simultaneously.Spacing between welding rod is set and is equaled amplitude of fluctuation.
The device that is proposed is used and is allowed the minor diameter thin wall pipe is carried out built-up welding.
