The specific embodiment
The embodiment of pipe butt joint apparatus described in the utility model is described below with reference to the accompanying drawings.Those of ordinary skill in the art can recognize, in the situation that not departing from spirit and scope of the present utility model, can to described embodiment, revise by various mode.Therefore, accompanying drawing is illustrative with being described in essence, rather than for limiting the protection domain of claim.In addition, in this manual, accompanying drawing draws not in scale, and identical Reference numeral represents identical part.
Fig. 1 is side view, from a direction, shows the pipe butt joint apparatus described in an embodiment of the present utility model; Fig. 2 is side view, from another direction, shows the pipe butt joint apparatus Fig. 1.As depicted in figs. 1 and 2, the pipe butt joint apparatus 100 described in an embodiment of the present utility model comprises the first counterpart part 10 and the second counterpart part 20.
The first counterpart part 10 comprises the first counterpart watts 11, first handle 12 and socket portion 13, wherein, the first counterpart watts 11 is for semi-circle tubular and offer the first welding window 111, first handle 12 is fixed on a straight flange of the first counterpart watts 11, and 13, socket portion is fixed on another straight flange of the first counterpart watts 11.
The second counterpart part 20 comprises the second counterpart watts 21, second handle 22 and tongue portion 23, wherein, the second counterpart watts 21 is for semi-circle tubular and offer the second welding window 211, second handle 22 is fixed on a straight flange of the second counterpart watts 21, and 23, tongue portion is fixed on another straight flange of the second counterpart watts 21.
The internal diameter of the internal diameter of the first counterpart watts 11 and the second counterpart watts 21 is identical, and more bigger than the external diameter of two pipelines for the treatment of butt welding, therefore, when the first counterpart watt the 11 and second counterpart watts 21 fastens, two pipe rings treating butt welding can be embraced, thereby make this two accurate counterparts of pipeline.
In socket portion 13 and tongue portion 23, at least one is curved shape.For example, in the present embodiment, tongue portion 23 is bending.Tongue portion 23 can insert in socket portion 13.When tongue portion 23 inserts in socket portion 13, for example, if (apply suitable power in opposite directions on first handle 12 and second handle 22, the grip of operating personnel's hand), can there is slight strain in socket portion 13 and tongue portion 23, thereby two straight flanges of two straight flanges that can make the first counterpart watts 11 and the second counterpart watts 21 are distinguished involutory.
Fig. 3 is side view, shows the use state of the pipe butt joint apparatus 100 described in the present embodiment; Fig. 4 is the partial enlarged drawing of circle part in Fig. 3.As shown in Figure 3 and Figure 4, when 100 pairs of two pipelines 200 of pipe butt joint apparatus described in using the present embodiment carry out butt welding, first make the first counterpart part 10 of pipe butt joint apparatus 100 and watt the 11 and second counterpart of the first counterpart on the second counterpart part 20 watts 21 around two pipelines 200 treating butt welding, and in the socket portion 13 that tongue portion on the second counterpart part 20 23 is inserted on the first counterpart part 10, then the first handle 12 on the first counterpart part 10 and the second counterpart part 20 and second handle 22 are applied to power F (for example grip of operating personnel's hand) in opposite directions, so that there is slight deformation in socket portion 13 and tongue portion 23, so, two straight flanges of the first counterpart watt the 11 and second counterpart watts 21 fasten respectively, thereby tightly fasten two pipelines 200 to be welded, make its accurate counterpart.Last by the second welding window 211 (referring to Fig. 1) in the first welding window 111 (referring to Fig. 1) in the first counterpart watts 11 or the second counterpart watts 21, carry out pipeline welding operation again.
In the present embodiment, when two straight flanges of the first counterpart watt the 11 and second counterpart watts 21 fasten respectively, first handle 12 and second handle 22 also combine.Yet the utility model is not limited to this.
Fig. 5 is side view, shows the use state of the pipe butt joint apparatus described in another embodiment of the present utility model.As shown in Figure 5, when the first counterpart watt the 11 and second counterpart watts 21 fastens, between first handle 12 and second handle 22, also can be certain angle, for example be greater than 0 °, be less than an angle of 45 °, facilitate like this welding job personnel to hold, and conveniently first handle 12 and second handle 22 are applied to grip.
In addition, although do not illustrate in the accompanying drawings, but the end at first handle 12 and second handle 22 can also be provided with a pair of corresponding securing member, when two straight flanges of two straight flanges of the first counterpart watts 11 and the second counterpart watts 21 are involutory respectively, by this, to securing member, can make first handle 12 and the fastening combination of second handle 22, thereby the pipeline 200 of counterpart the relative changing of the relative positions can not occur while guaranteeing welding, can reduce the fatigue strength of operating personnel's hand simultaneously.
Known from description above and practice, the pipe butt joint apparatus that the utility model provides is simple in structure easy-to-use, when the small-bore pipeline of solid matter is carried out to butt welding, only need be by the first counterpart part of this pipe butt joint apparatus and the first counterpart on the second counterpart part watt and the second counterpart watt around the pipeline for the treatment of butt welding, then tongue portion on the second counterpart part is inserted in the socket portion on the first counterpart part and to first handle and second handle on the first counterpart part and the second counterpart part and applies power in opposite directions, the grip of hand for example, can make the first counterpart watt and the second counterpart watt fastening, thereby make the accurate counterpart of pipeline to be welded, last by the welding window in the first counterpart watt and the second counterpart watt, can carry out welding operation again.Said process can complete rapidly easily, thereby, pipe butt joint apparatus described in the utility model is specially adapted to the small-bore pipeline of a large amount of solid matters to carry out butt welding, can effectively improve butt welding of pipelines efficiency and welding precision and reduce staff's labour intensity.
Should be noted that in the utility model, those of skill in the art can carry out various improvement, distortion and combination on the basis of above-described embodiment, and these improve, are out of shape and combine also all within protection domain of the present utility model.Should be understood that above-mentioned specific descriptions are just used for illustrating the utility model, protection domain of the present utility model is limited by appended claims and equivalent thereof.
