Abstract
The utility model relates to a wear resistant belt welding device for a drill rod joint in the petroleum drilling technology, which is composed of a drill rod 2, a power supply 5, a welding wire 6, a wire feeder 7, a welding torch 10, etc. One terminal of the power supply 5 is connected with the welding torch 10, the other terminal is connected with a working piece, the wire feeder 7 is hung above an adjusting column 9, the wire feeder 7 is connected with a welding chamber 10 through an electric bundle wire 8, the wire feeder 7 is provided with the welding wire 6, the wear resistant belt of the drill rod joint welded by the medicine core air protecting automatic welding torch has the advantages of medium hardness, good wear resistance, low friction coefficient, good power property, stable electric arc and large welding depth, no preheating is needed before welding, no heat preservation is needed after welding, the rotation of a clamping disk can be regulated according to the width and thickness of the wear resistant belt, and according to the electric arc and the surface condition of the wear resistant belt when the wear resistant belt is welded, the parameters, such as height, angle, etc. of the welding torch and the working piece can be adjusted.
Description
The utility model relates to the wear-resisting tape welding system new equipment of tool joint of protecting tool joint, sleeve pipe not to be crossed quick-wearing in the petroleum drilling technology.
In the Process of Oil Well Drilling, drilling rod will rotary drilling in rock or sleeve pipe, because tool joint is bigger than drill pipe diameter, so at first be worn, when may wear to a certain degree, tool joint will be scrapped, and cause drilling rod overhaul (replacing joint).Creep in sleeve pipe, sleeve pipe also can be worn, and the wearing and tearing between drilling rod and joint and rock, the sleeve pipe also cause the loss of drilling well power, increases the consumption of fuel.
Current domestic petroleum system extensively adopts the wear-resisting band of method weldering system tool joint of plasma spray iron alloy powder, its shortcoming is that to creep into service life in rock shorter, in sleeve pipe, creep into, bigger to casing wear, coefficient of friction between this wear-resisting band and the sleeve pipe is bigger simultaneously, cause power loss bigger, and plasma spray can cause radioactive pollution, the weldering control equipment is comparatively complicated.
The purpose of this utility model be to provide a kind of reduce the wearing and tearing of tool joint, sleeve pipe and improve do not have the wear-resisting tape welding system new equipment of alpha-contamination tool joint its service life.
The utility model is achieved in that by roller 1, drilling rod 2, joint 3, chuck 4, power supply 5, welding wire 6, wire-feed motor 7, electricity forms line 8, adjusting column 9, welding gun 10, regulating arm 11, drilling rod 2 is arranged on the roller 1, joint 3 is enclosed within on the drilling rod 1, chuck 4 is arranged on the drilling rod, power supply 5 one ends are connected with welding gun 10, the other end is connected with workpiece, wire-feed motor 7 hangs over the top of regulating column 9, wire-feed motor 7 is connected line 8 by electricity with weldering chamber 10, welding wire 6 is arranged on the wire-feed motor 7, and there is regulating arm 11 top of regulating column 9.
The utility model also is achieved by the following scheme: power supply 5 selects for use NBC500 direct current gas to protect semi-automatic power supply.
The positive pole of power supply 5 connects workpiece, and negative pole connects welding gun 10.
It is protective gas that power supply 5 adopts argon gas.
In the welding gun 10 flux-cored wire is arranged.
Advantage of the present utility model is: used welding gun is that medicine core gas is protected automatic welding gun, the hardness of the wear-resisting band of tool joint that welds out moderate (HRC50-55), wearability is good, coefficient of friction is little, owing to adopt high-power, direct current hardware features gas is protected automatic welding power supply and corresponding wire feed system, this power supply characteristic is good, arc stability, fusion penetration is bigger, and workpiece can not preheating before weldering, postwelding can not be incubated, it is qualified that its wear-resisting band crackle can guarantee, can be according to the width of wear-resisting band, thickness is adjusted the chuck revolution, electric arc in the time of can making wear-resisting band according to weldering, wear-resisting belt surface situation is adjusted welding gun and workpiece height, parameters such as angle.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described further:
By roller 1, drilling rod 2, joint 3, chuck 4, power supply 5, welding wire 6, wire-feed motor 7, electricity line 8, adjusting column 9, welding gun 10, regulating arm 11 are formed, drilling rod 2 is arranged on the roller 1, joint 3 is enclosed within on the drilling rod 1, chuck 4 is arranged on the drilling rod, and power supply 5 one ends are connected with welding gun 10, and the other end is connected with workpiece, wire-feed motor 7 hangs over the top of regulating column 9, wire-feed motor 7 is connected line 8 by electricity with weldering chamber 10, welding wire 6 is arranged on the wire-feed motor 7, and there is regulating arm 11 top of regulating column 9.
Power supply 5 selects for use NBC500 direct current gas to protect semi-automatic power supply.
The positive pole of power supply 5 connects workpiece, and negative pole connects welding gun 10.
It is protective gas that power supply 5 adopts argon gas.
In the welding gun 10 flux-cored wire is arranged.
Select for use NBC500 direct current gas to protect the minor arc of semi-automatic power supply replacement plasma spray, pay two power supplys of arc, make arc stability.
Used NBC500 wire-feed motor, electrode holder line, welding gun adapt to the needs of novel φ 2.0mm flux-cored wire.Automatically the weldering welding gun is fixed on the fork of former plasma spray welding gun, and wire-feed motor hangs over the top of regulating the column back of the body.
