MOVABLE SUPPORT OF A PIPELINE Russian patent published in 2005 - IPC

FIELD: the invention refers to construction and used at building overhead pipelines.

SUBSTANCE: the movable support has a girth rail fixed on the foundation of the support, a lodgment, hinges with two degrees of freedom and poles with stiffening rings. The support has additionally two beams, two supporting sleeves and four regulation mechanisms. As hinges the heads of the dynamo measuring sensors with spherical supporting surfaces are used and as poles - two cylindrical columns whose upper faces are firmly connected with the foundation of the dynamo measuring sensors, and low faces - with the girth rail. The central parts of the beams are leaning through supporting sleeves on spherical surfaces of the heads of the dynamo measuring sensors, the edges of the beams are connected travellingly and symmetrically relatively to the supporting sleeves with a lodgment with the help of the regulation mechanisms. At changing of the designed height of the support's edge the load on the dynamo measuring sensors changes and correspondently the variable output signal from the sensors which passes through control apparatus and enters the input of the regulation mechanism whose electric engine through a reduction gear rotates the regulation propellers until restoration of the load on the support to standard magnitude corresponding to the designed position of the support.

EFFECT: increases reliability of the pipeline and that is achieved by the way of remote control of the height of the support for conservation of the designed position of the pipeline.
