Description

Three-section type petroleum pipeline connecting device Technical Field The utility model relates to the technical field of petroleum pipeline connection, in particular to a three-section petroleum pipeline connection device. Background In the petroleum conveying process, the connection of petroleum pipelines is an important link, namely pipeline oil conveying is to convey crude oil from one place to another place through the oil conveying pipelines under pressure, and the purpose of the pressurization is to provide kinetic energy for the crude oil so as to overcome the geographical difference along the line and the pressure loss along the pipeline, and two major parts of oil conveying stations and lines are needed for realizing long-distance conveying of the crude oil; The existing mechanism generally fixes the pipeline through the tensioning assembly and the connecting assembly, and is inconvenient to detach and treat the independent pipeline when the pipeline is detached, changed and installed, so that the integral use of the device is affected. Through retrieving, the chinese patent with the bulletin number CN221237342U discloses a petroleum pipeline connecting device, this structure is with the help of the locating component in the mount pad, the pulling slide bar can drive the connecting band, and then make the swivel remove, promote the piece compression reset spring, meshing with the meshing wheel when the swivel removes, let meshing wheel and lead screw rotate, because of locating pin and lead screw thread fit, the locating pin just can withdraw, spacing alignment installation cavity spacing groove on the mounting disc this moment, loosen the slide bar after inserting the mounting disc, reset spring makes the locating pin stretch out and insert the locating hole, accomplish the mounting disc location, its advantage lies in pulling the slide bar just can install the mounting disc fast, and the condition that need two oil pipes of synchronous operation when the both sides locating component can avoid dismantling or change oil pipe prevents to appear operation confusion, effectively guarantee the smooth development of follow-up work, promote work efficiency. However, when the structure is in actual use, the reset spring is in a compressed and reset state for a long time, and is easy to cause fatigue failure, so that enough elastic force cannot be provided to enable the positioning pin to accurately extend out and be inserted into the positioning hole, and the overall stability is affected.
