Safe and efficient supporting device for oil and gas pipeline and oil and gas pipeline system

Abstract

The invention discloses a safe and efficient supporting device for an oil and gas pipeline and an oil and gas pipeline system. The safe and efficient supporting device comprises a supporting mechanismand a pipeline clamping assembly arranged at the top of the supporting mechanism. The supporting mechanism comprises a bottom supporting column, a top supporting column and a wedge transmission assembly. A step containing groove is formed in the bottom supporting column, and a spring is placed in the step containing groove. A locking part axially extends from the bottom edge of the top supportingcolumn. The wedge transmission assembly comprises a first wedge piece and a second wedge piece which are in wedge fit. The wedge transmission assembly has a locking position and an unlocking position. At the locking position, the wedge transmission assembly is located in the groove wall of the step containing groove. At the unlocking position, the top of the second wedge piece supports the bottomface of the top supporting column. According to the safe and efficient supporting device for the oil and gas pipeline and the oil and gas pipeline system, when a supporting foundation such as a stratum moves downwards, the supporting mechanism can be lengthened and still maintain certain supporting force, and therefore, the anti-seismic capacity for stratum downward movement is achieved.

Description

technical field [0001] The invention relates to oil and gas equipment, in particular to a safe and efficient support device for oil and gas pipelines and an oil and gas pipeline system. Background technique [0002] Pipeline transportation is second only to shipping for oil and gas transportation. For example, the oil and gas pipeline from Xinjiang to the mainland, and the oil and gas pipeline from Russia to Northeast China, etc., are important energy arteries in my country. [0003] In theory, the layout of oil and gas pipelines should avoid seismic zones. However, in reality, the layout of long-distance oil and gas pipelines is limited by the start and end points, terrain, maximum bending of pipelines, and even power transmission conditions. It is inevitable to pass through earthquakes. At this time, it is necessary to install an anti-vibration device for the supporting structure of the pipeline. For example, the application publication number is 201710906101.9, and the ap...

Problems solved by technology

[0004] The disadvantage of the existing technology is that when an earthquake occurs in the seismic zone, the ground supporting the pipeline device may be displaced, such as a certain degree of subsidence. The above-mentioned existing patents can only adjust the torsion of the pipeline caused by the vibration, but cannot adjust the ground It is not safe and efficient enough to adjust the downward movement
