Abstract

The invention relates to a pipeline support hanger used in a thermodynamic system, and belongs to the technical field of support hangers. The invention aims to provide a support hanger with a function of "gradually increasing load when a hanging point moves upwards". The support hanger comprises lifting lugs, a frame body, a lever, the hanging point, a main shaft, a lower limit, an adjustable connecting rod, a counter weight, a sliding block and a horizontal limit, wherein rigid components are connected into a connecting rod mechanism through a lower pair. The connecting rod mechanism utilizes the lever principle, and the change of the length of a long arm in the movement process of a lever generates the effect of increasing the load of the support hanger, so that the function that the load is gradually increased when the hanging point moves upwards is achieved; and the length of the adjustable connecting rod can be adjusted within a certain range, and the function that the load change rate is adjustable is achieved. The support hanger can be used for controlling pipe system sinking, improving pipeline deformation, optimizing pipe system stress state and the like.

Description

technical field [0001] The invention belongs to the technical field of support and hangers, and in particular relates to a pipeline support and hanger used in a thermal system. Background technique [0002] There are various thermal pipelines in thermal systems (such as thermal power generation, petrochemical, metallurgical, etc.), including steam pipelines, steam-water pipelines, etc. The support and hanger is an important part of the pipeline system, including various components or devices used to bear the load, limit the displacement, control the vibration, and transfer the load to the bearing structure (civil foundation, etc.). The safe and stable operation of various thermal pipelines is of great significance. [0003] At present, the commonly used supports and hangers in thermal systems include variable force spring supports (hereinafter referred to as spring hangers), constant force spring support hangers (hereinafter referred to as constant hangers), rigid support h...
