The specific embodiment
Referring to Fig. 1～shown in Figure 7: a kind of jack type external clamp, it includes: first ring flat-plate 1 and second ring flat-plate 2, in one side of this first ring flat-plate 1 and second ring flat-plate 2 rotating shaft 3 that is hinged is installed, be provided with 4 school circle briquettings 4 at first ring flat-plate 1 and second ring flat-plate 2 inboards, be that 4 plug weldings of high-ranking officers' circle briquetting are in notch 18, on another side of first ring flat-plate 11, be welded with a sleeve pipe 14, in this sleeve pipe 14, placed a transverse axis 15, sleeve pipe 14 is stretched out at the two ends of this transverse axis 15, on the two ends of transverse axis 15, hang with two link plates 6, be welded with a base plate 7 in the bottom of two link plates 6, base plate 7 is provided with hydraulic jack 16; Being connected with a lower platen 5 on another side of second ring flat-plate 2, is that lower platen 5 plug weldings are connected in the open slot 8, and the upper end of described hydraulic jack 16 is in the bottom of lower platen 5.
Side at first ring flat-plate 1 is provided with inner bolt hole 11, respectively weld a block plate 13 in the both sides of second ring flat-plate 2, and screw 12 outside on two block plates 13, being respectively equipped with, described rotating shaft 3 penetrates described inner bolt hole 11 and outer screw 12, and a side of first ring flat-plate 1 and second ring flat-plate 2 is hinged.
Be provided with 4 school circle chock open slots 9 at first ring flat-plate 1 and second ring flat-plate 2 inboards.During use, can in school circle chock open slot 9, insert school circle chock 17,, reach and correct the concentrically ringed purpose of the mouth of pipe by the extruding of 17 pairs of pipe ends of school circle chock.
The quantity of school circle briquetting 4 and school circle chock open slot 9 can increase according to actual conditions, but its sum should be even number and is uniformly distributed along the circumference.
In order to alleviate the weight of the utility model external clamp, the uniform lightening hole 10 that is cut with on first ring flat-plate 1 and second ring flat-plate 2, its diameter and quantity can be grasped flexibly according to actual conditions.
Before the counterpart, will polish flat and rounding off in the spiral weld of pipe end or the straight weld 30mm scope earlier.This is stuck on the side pipe mouth mouthpart, with the opposite side pipe insert adjust the counterpart gap after, lift second ring flat-plate 2 of mouthpart, lower roof plate 5 on second ring flat-plate 2 is withstood on the hydraulic jack 16, will be thereby start jack to second ring flat-plate jack-up of mouthpart, by the circle briquetting of the school on the mouthpart 4 extruding mouths of pipe being reached the purpose of school circle; If only the position that does not still reach requirement with the extruding of school circle briquetting can reach requirement by squeezing into steel school circle chock 17 from school circle chock open slot 9.
