Supporting assembly for steam pipeline

Abstract

The invention provides a supporting assembly for a steam pipeline. The supporting assembly is installed between the steam pipeline sleeved with a heat preservation layer and a support column and comprises a fixed base, supporting plates and a plurality of fixed rods, and the fixed base, the supporting plates and the fixed rods are of an integrally-formed structure; the heat preservation layer is in cooperative lap joint with the interior of the arc surfaces of the upper ends of the supporting plates, the fixed rods are connected to the upper ends of all the supporting plates, and a measuring device is inserted into the fixed rods and comprises a measuring rod, a linkage rod, a distance measuring rod and a distance measuring sensor; a rotary rod is inserted in the column, the linkage rod ishinged to the rotary rod, a magnetic block is fixedly installed on the linkage rod and is in attraction connection with the distance measuring rod, the column is provided with a distance measuring blind hole, the distance measuring sensor is installed at the hole bottom of the distance measuring blind hole, the end, away from the linkage rod, of the distance measuring rod is cooperatively inserted in the distance measuring blind hole, the distance measuring sensor is utilized for monitoring the thermal deformation of the steam pipeline in real time, and the phenomenon of pipeline falling caused by thermal deformation is avoided.

Description

technical field [0001] The invention relates to the technical field of steam pipeline detection, in particular to a steam pipeline support assembly. Background technique [0002] In the steam production site, since the temperature of the steam transported is above 100°C, the transportation pipeline is in a high-temperature environment for a long time, and thermal deformation will occur after a long period of use, especially at the bend of the pipeline, where thermal stress and Bending stresses cannot offset each other, and the degree of deformation is higher. The transportation pipeline is usually spliced ​​with seamless steel pipes to form a steam pipeline network. The deformation of the pipeline will cause the center of gravity of the steam pipeline to shift. This shift process exists at a higher place, and the relevant staff is not easy to find out. Therefore, the distance measuring sensor is often used to monitor the deformation of the steam pipeline in real time. When t...

[0002] In the steam production site, since the temperature of the steam transported is above 100°C, the transportation pipeline is in a high-temperature environment for a long time, and thermal deformation will occur after a long period of use, especially at the bend of the pipeline, where thermal stress and Bending stresses cannot offset each other, and the degree of deformation is higher. The transportation pipeline is usually spliced ​​with seamless steel pipes to form a steam pipeline network. The deformation of the pipeline will cause the center of gravity of the steam pipeline to shift. This shift process exists at a higher place, and the relevant staff is not easy to find out. Therefore, the distance measuring sensor is often used to monitor the deformation of the steam pipeline in real time. When the distance measuring sensor is used Fitted with steam pipes, its own plastic shell is affected by high temperature and is easily damaged by melting, which poses a certain safety hazard
