Abstract

The invention discloses a dual-locking flange positioner used for the welding alignment of a flange and a pipeline, consisting of a positioning device and a dual-locking device; when the positioning of the flange is carried out, without the aligning and adjusting operation of the parallel surface and coaxiality of the flange, the quality can be ensured and the positioning is quick and exact; when the dual-locking flange positioner is used, the flange is firstly sheathed on the end of the pipeline; a positioning shaft is inserted into the pipeline; the pipe end pushes against a flange tensioning block; the flange is then leaned on a positioning plate; a driving wheel is pulled by a ratchet wrench so as to lead the pipeline tensioning block to expand the pipeline; the ratchet wrench can quickly and easily move on a rear pulling rod; the ratchet wrench is rotated to lead the rear pulling rod to pull a rear conical column so as to lead the flange tensioning block to expand the flange; the flange parallel surface and coaxiality positioning is completed; therefore, the labour force is saved by 50 percent and the working efficiency is improved by more than 10 times.
本发明公开了一种用于法兰和管道焊接找正的双锁紧法兰定位器,由定位装置和双锁紧装置组成,完成法兰定位时,不对法兰的平行面、同轴度进行找正调整操作,就能保证质量、快速准确定位,使用双锁紧法兰定位器时,先把法兰套在管道端,再把定位轴插入管道内,是管端顶住法兰张紧块,然后把法兰靠住定位板,用棘轮扳手扳动传动轮使管道张紧块张紧管道,棘轮扳手能够快速容易的移动到后拉杆上,转动棘轮扳手使后拉杆拉动后锥柱,使法兰张紧块张紧法兰,法兰平行面、同轴度定位完成,节省劳动力50%,提高工效10多倍。
