As shown in Figure 1A-1F, electric welding machine bonding body comprises according to an embodiment of the invention: snap ring 5,For being arranged on pipeline 11(to be welded referring to Fig. 3 and Fig. 4); Bonding 1, is fixed on snap ring 5On; Wire fixture, for by electric welding machine wire 14(referring to Fig. 3 and Fig. 4) be fixed on bonding 1.Because electric welding machine wire 14 is connected to bonding 1, the current loop therefore can utilize bonding 1 to form welding time.
Preferably, on snap ring 5, be provided with the first hole 21, simultaneously at the first hole 21 places,On snap ring 5, be provided with securing member. Securing member can integrally be processed with snap ring 5, also can separately addWork, the present invention is for the ease of processing and strengthen the intensity of securing member, preferably, integral processing. For example,Securing member can comprise the first baffle plate 112 of being arranged on snap ring 5 one end, be fixed on the first baffle plate 112On the second bolt 9, be arranged on the second baffle relative with the first plate washer 112 on snap ring 5 other ends114, be arranged on second baffle 114 and for making through hole that the second bolt 9 passes and with secondThe second nut 10 that the external screw thread of bolt 9 matches. The second bolt 9 on the first plate washer 112 is passedAfter through hole on second baffle 114, then by tightening fastening the first plate washer 112 of the second nut 10 andTwo baffle plates 114, the first hole 21 on closed snap ring 5, makes snap ring 5 hold pipeline tightly.
According to one embodiment of present invention, snap ring 5 can be provided with more greatly and only one by an elasticityThe metallic object of hole (, the first hole 21) forms.
According to another embodiment of the invention, for the ease of snap ring 5 is fixed on to pipeline to be welded 2Upper, preferably, snap ring 5 has two and is for example roughly semicircular body (the first noumenon 26 and secondBody 27), the first noumenon 26 is connected by being flexibly connected assembly with the second body 27, described activityCoupling assembling is arranged on the relative position of described the first hole 21. Referring to Figure 1B, Fig. 2 A, Fig. 2 B,This flexible connection assembly can comprise the first axle sleeve 122 of being arranged on the first noumenon 26 one end, be arranged onThe second axle sleeve 123 on second body 27 one end and connection the first axle sleeve 122 and the second axle sleeve 123Hinge axis 8, so that the first noumenon 26 and the second body 27 can rotate around hinge axis 8. Meanwhile, forThe first axle sleeve 122 is closely connected with the second axle sleeve 123, preferably, on snap ring 5 arrange firstThe quantity of axle sleeve 122 can be 1, and the quantity of the second axle sleeve 123 arranging on snap ring 5 can be 2Individual, and distance between two the second axle sleeves 123 is identical with the width of the first axle sleeve 122, so thatBetween one axle sleeve 122 and the second axle sleeve 123, can intersect chain connection, vice versa (, the first axleThe quantity of cover 122 can be 2, and the quantity of the second axle sleeve 123 can be 1). It is pointed out thatThose skilled in the art is known, and the present invention is not limited to this, as long as can be by the first noumenon 26 andThe connecting elements that two bodies 27 are flexibly connected mutually all can.
In this exemplary embodiment, wire fixture can comprise the first bolt being fixed on bonding 14 and the first nut 3 of matching with the external screw thread of the first bolt 4. Meanwhile, in order to make electric welding machine bonding bodyFirmly, preferably, the first bolt 4 is fixed on the junction of bonding 1 and snap ring 5 to entirety. In addition, alsoCan, below the first nut 3, pad 2 be set above electric welding machine wire 14, by tighteningOne nut 3 and apply downward power to pad 2, thus pad 2 is pressed in electric welding machine wire 14 tightlyBetween pad 2 and bonding 1.
In addition, according to another embodiment of the invention, for fear of conduction between snap ring 5 and bonding 1Thereby burn pipeline mother metal, can allow snap ring 5 there is certain flexible material and form by nonconducting,For example, can be formed by insulation hard rubber. Or snap ring 5 also can still be formed by metal material, butBetween snap ring 5 and bonding 1, use insulation to connect, for example, the portion being fixedly connected with bonding 1 of snap ring 5Divide and have insulator, bonding 1 is fixed on this insulator.
Below with reference to Fig. 3 and the concise and to the point electric welding machine bonding body of describing exemplary embodiment of the present invention of Fig. 4Bridging method.
With reference to Fig. 3, the securing member on snap ring 5 is being opened, snap ring 5 is fixed on to pipeline to be weldedOn 11 polyvinyl chloride anticorrosive coat 13, for avoiding bonding body at when welding pipeline mother metal of burning, snap ring 5Fixed position to meet the weld bond of welding that bonding 1 can touch pipeline to be welded 11 can (takeIron 1 is overlapped on weld bond, the weld bond of can only burning, and weld bond after burning can polish and repair;And if bonding 1 is overlapped on pipeline mother metal, burn pipeline mother metal this pipeline will scrap, and needDo over again, this is that inventor obtains through design and the thinking of novelty); Secondly, by the first plate washer 112On the second bolt 9 through the through hole on second baffle 114, and by the second nut 10 shackles 5;Again, electric welding machine wire 14 is arranged on for example, on (, being wrapped in) first bolt 4, then installs successivelyPad 2 and the first nut 3, fix electric welding machine wire 14 by tightening the first nut 3; Finally, toElectric welding machine energising, welds pipeline to be welded.
With reference to Fig. 4, its bridging method and Fig. 3's is similar, and difference is, the position that bonding 1 overlapsOn the weld bond also not welded, even if burn like this weld bond, the not weldering weld bond after burningStill can be soldered, can polish and repair when the time comes.
Unless have in addition contrary description, otherwise the description of feature or aspect is recognized in each embodimentFor being similar feature or the aspect being applicable in other embodiment.
For the object that promotes the understanding to principle of the present invention, to the preferred enforcement shown in accompanying drawingExample is illustrated, and has used specific language to describe these embodiment.
