The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of outer contra-aperture device of pipeline that can adjust the pipeline section spacing that the utility model embodiment provides comprises a double-ring mouth of pipe centering fastener and a double-ring pipeline section spacing regulator.Double-ring mouth of pipe centering fastener comprises two parallel beckets 1, width between two beckets 1 is 40cm, and two beckets 1 are two semicircle open architectures, and an end is connected by bearing 3, other end opening, opening two ends are provided with the latch segment 4 that is complementary.Two becket 1 inner rings evenly are provided with parallel fixed block 2, fixed block 2 is the fixed block of rectangle for the cross section, and the quantity of fixed block 2 is the 8-10 piece, in the present embodiment, fixed block 2 is set to 10, and the interior circular diameter that fixed block 2 surrounds equals the overall diameter of the body of required centering.Double-ring pipeline section spacing regulator comprises two parallel beckets 5, two 5 of beckets evenly are provided with parallel bolt 6, the quantity of bolt 6 is 4-8, in the present embodiment, bolt 6 is set to 4, every bolt 6 long 60mm, two beckets 5 are two semicircle open architectures, one end is connected by bearing 7, other end opening, the opening two ends be provided with can clamping buckle piece 8.
A kind of operation principle that can adjust the outer contra-aperture device of pipeline of pipeline section spacing that the utility model embodiment provides is: two beckets 5 with double-ring pipeline section spacing regulator are enclosed within two sections tube section ends that need centering respectively, snapping buckle piece 8 makes two beckets 5 be held in the mouth of pipe end of two sections pipeline sections respectively, by the spacing of tightening up and release bolt 6 is adjusted between two beckets 5, thereby drive two sections pipeline sections and move fore-and-aft distance between the mouth of pipe of adjusting two pipeline sections, the requirement of weld width when satisfying welding.Then double-ring mouth of pipe centering fastener is enclosed within on the double-ring pipeline section spacing regulator, the outer wall of the two sections pipeline sections of fixed block 2 contacts on the double-ring mouth of pipe centering fastener becket 1, apply fastening strength by a thousand pieces of gold top or fastening bolt at latch segment 4 places, because the diameter of a circle that fixed block 2 inner surfaces on the becket 1 are surrounded is consistent with the external diameter of two sections pipeline sections, therefore when the latch segment 4 of double-ring mouth of pipe centering fastener constantly tightens up, fit the gradually surface of two sections pipeline sections of the inner surface of fixed block 2, the mouth of pipe of two sections pipeline sections is finally finished horizontal centering.
A kind of outer contra-aperture device of pipeline that can adjust the pipeline section spacing that the utility model embodiment provides, the requirement of weld width in the time of not only can satisfying in the engineering the needs of scene welding body centering and welding, and this device also has simple in structure, with low cost, characteristics such as easy to carry, simple to operate.
It should be noted last that, the above specific embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to example, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
