Description
Technical field
This utility model relate to a kind of mat formation under water pipeline time the auxiliary equipment that uses, specifically a kind of pipe flange docking stopping means.
Background technology
Polluter smoking pipeline is the important component part of city sewage treatment works; for improving the disposing capacity of coastal cities sewage, protection marine resources and environment, promote the sustainable development of marine economy; alleviating the sewage pollution to marine environment, polluter smoking pipeline is progressively developed to deep-sea by shallow sea.
Key element crucial when pipeline under water docks is intended to the flange installing pipeline section and pipeline section to be installed to align, and the method for prior art typically uses duration, and efficiency is low, costly.
Utility model content
Problem to be solved in the utility model is to provide a kind of pipe flange Fast Installation stopping means, both can adjust axiality and the flange bolt centerline deviation of abutted flange, can guarantee that again the high efficiency installing/dismounting of device.
For solving above-mentioned technical problem, pipe flange Fast Installation stopping means of the present utility model, including the Cornu Caprae seu Ovis limiting plate on the flange end face of dismountable butt end being arranged on and installing pipeline section, described Cornu Caprae seu Ovis limiting plate is fixedly installed, towards the side of end, the latch that at least two position matches with flange bolt hole, the opposite side of described Cornu Caprae seu Ovis limiting plate arranges two symmetrical fixing axles, it is respectively provided with screw on fixing axle, screws with the fixing bolt mated with screw and withstand pipeline；This device also includes the locating shaft on the flange end face of dismountable butt end being arranged on pipeline section to be installed, described locating shaft is fixing connects gripper shoe, gripper shoe arranges, towards the side of end, the latch that at least two position matches with flange bolt hole, screw is set on locating shaft, screws with the fixing bolt mated with screw and withstand pipeline.
When underwater flange connects, loop wheel machine hangs holds up pipeline section to be pacified slowly to be close to pacify pipeline section, and after making locating shaft overlap with Cornu Caprae seu Ovis bifurcation mouth, slowly pasture hooks and makes flange automatic capturing.Installing locating shaft at pipeline section abutted flange to be pacified, make spacing bearing pin sink in spacing Cornu Caprae seu Ovis by loop wheel machine lifting, it is ensured that flange docking level, bolt hole axle center is corresponding, accelerates bolt and interts retention efficiency.Weld latch on Cornu Caprae seu Ovis limiting plate, can dock with flange bolt hole, be allowed to be locked on flange, will not double swerve.Being welded and fixed axle on Cornu Caprae seu Ovis limiting plate, fixing axle is provided with screw and bolt, is possible to prevent limiting plate up and down after tightening.Fixing connection gripper shoe on locating shaft, it is also possible to fix with pipeline section and flange in the same way.
Described Cornu Caprae seu Ovis limiting plate is divided into left and right two panels, and on two panels Cornu Caprae seu Ovis limiting plate, two latches of difference, two panels Cornu Caprae seu Ovis limiting plate is respectively provided with fixing axle.Cornu Caprae seu Ovis limiting plate is into two pieces can more easily be dismantled.
Described fixing bolt arranges dismountable steel plate with the position of pipeline section joint.
After using such structure, pipe flange Fast Installation stopping means of the present utility model, can install with pipeline section and flange very easily, can quickly dismantle after being finished, can the levelness of high efficiency adjustment abutted flange and left-right deviation, connect for underwater flange bolt and rigid platform is provided, improve bolt to wearing speed.
