Description

Technical Field

[0001] The utility model relates to the technical field of pipeline fixing, in particular to a fixing device for an oil transportation pipeline. Background Art

[0002] Petroleum transportation, one of the components of fossil energy transportation, includes crude oil transportation and refined oil transportation. If the crude oil is imported, it is transported from the exporting country to the importing country's terminal by large tankers, and then transported to the refinery through pipelines. If it is produced domestically, it is distributed to refineries through pipelines, and refined oil is first distributed from the refinery to various oil depots, mainly by pipeline transportation, but also by railways, inland waterways, and automobiles. It is then distributed to users by oil depots, mainly relying on oil tanker transportation.

[0003] The existing authorized patent number is CN 218378308 U, which is a fixing device for an oil transportation pipeline. The fixing device includes a limit plate fixedly connected to the upper surface of a bracket and a detachable oil pipeline connected to one end of a cross pipe by bolts. The inner wall of the limit plate is clamped with a retractable support, and the surface of the support is sleeved with a spring that can laterally absorb shock. One end of the support is fixedly connected to a limitable clamping plate, and the lower surface of the clamping plate is fixedly connected to a supportable limit ring.

[0004] The above equipment has a reasonable structure. Through the arrangement of the bracket, pillar, spring and limit ring, the construction personnel can fasten the limit ring to the surface of the oil pipeline through the tightening column, the bracket can be pressed against the ground, and the supporting effect is good. The pipeline will produce certain vibrations during operation, and the pillar can move left and right inside the limit plate. The spring is located between the limit plate and the clamping plate, which is beneficial to reduce the vibration generated by the oil pipeline during oil transportation, and has a good shock absorption effect. At the same time, it is also convenient for construction personnel to install and use it, and the fastening effect is good and the installation efficiency is high. However, through the arrangement of the bracket, pillar, spring and limit ring, the construction personnel can fasten the limit ring to the surface of the oil pipeline through the tightening column, the bracket can be pressed against the ground, and the supporting effect is good. However, the placement height of the existing fixing device for oil transportation pipelines is difficult to adjust, which can affect the connection of the oil transportation pipeline. In special environments, the oil transportation pipeline needs to adjust the height for connection. Utility Model Content
