Description

Multidirectional deflection preventing device for spring support and hanger Technical Field The utility model belongs to the field of petrochemical industry, relates to a spring support and hanger technology, and in particular relates to a multidirectional deflection preventing device for a spring support and hanger. Background The pipeline support and hanger is an important component of a pipeline system and has the functions of bearing pipeline load, limiting pipeline displacement, controlling pipeline vibration and the like. The spring support and hanger is an important pipeline bearing support and hanger and has wide application in petrochemical equipment. Due to the effect of thermal expansion and contraction, the pipeline supporting and hanging part and the structural supporting part can generate relative thermal displacement in the vertical direction. In this case, a spring hanger is selected to support the load of the pipe. The spring support and hanger utilizes the load deformation characteristics of elastic support elements such as a cylindrical spiral spring, a disc spring and the like to support a pipeline with vertical relative thermal displacement, so that the problem of void or overload of the pipeline is prevented, the stress of the pipeline and equipment is controlled within a reasonable range, and the guarantee is provided for the safe operation of the pipeline, the equipment and the device. In the practical application process, when the pipeline and the spring support and hanger move horizontally and relatively, the load column is subjected to the friction force in the horizontal direction besides the pipeline load in the vertical direction, and the friction force generates a rotation moment on the load column, so that the load column is deflected. The greater the pipe load, the greater the horizontal displacement, the lower the deflection capability of the spring hanger itself, and the greater the likelihood of deflection of the load column. Deflection of the spring hanger load post is a common problem. The deflection of the load column can cause deflection, distortion and abrasion of the elastic element, the spring support and the hanger are blocked and even fail, the output load of the spring support and the hanger deviates from a design value, and the stress state of the pipeline is unpredictably changed, so that the safe operation of the pipeline and equipment is affected.
