Description
Technical field
The present invention relates to field of petroleum machinery, and in particular to a kind of petroleum pipeline welding line-up clamp.
Background technique
Controlling methodology of oil pipeline, i.e., for transporting the pipe-line system of petroleum and oil product, mainly by petroleum pipeline, oil transportation station
And other auxiliary phases close equipment composition, are that one of capital equipment of oil movement and storage industry and crude oil and oil product are main
Conveying equipment, compared with the railway and highway oil transportation that belong to land transportation mode, pipeline oil transportation has that freight volume is big, airtightness
Good, the features such as at low cost and safety coefficient is high.
Oil pipeline must use certain on-link mode (OLM) that could constitute a complete system.The connection type of pipeline is main
There are screw thread, welding and flanged joint three classes.Higher for pressure, the stringent route of sealing requirements is substantially all using the side of welding
Formula.Pipeline requires to use line-up clamp in advance when welding, and guarantees the precision that the position at two pipeline docking is stable and welds.
Common line-up clamp is divided into, external clamp and internal clamp, and structure is complicated that input cost is higher for internal clamp, and outer
Line-up clamp sexual intercourse is simply easy to use to be widely adopted.Although external clamp structure at present on the market is simple, on the one hand exist
There is certain blocking to the operation of welder in use process, another party not can be carried out and be adjusted axially, and the caliber of adaptation is also more single
One.
Chinese patent document CN106826080B disclose " a kind of pipeline welding external clamp ", it can be achieved that be adjusted axially and
The function of automatic welding, but the patented product there is also fixed ring fixed -pipings in actual use built on the sand, adjust ring
When caliber change is larger twisting adjust bolt time is longer, working efficiency is lower, rotating block is on gear ring due to being rubbed
The case where clashing existing Caton, shake, and then the problems such as influence welding quality.In addition to this, in that patent due to adjusting bolt
It is not synchronous rotary, is easy to appear the oil pipeline adjusted adjusted in ring to the end not at the center for adjusting ring, to make axial direction
Fine-tuning nut, due to the non-face of two sides bolt, and is influenced to be adjusted axially the longevity with connection screw thread by additional torque when adjusting
Life.
