Constant support and hanger

Abstract

The invention discloses a constant support and hanger which comprises a shell, a pull rod assembly, a locking device and a load assembly. The load assembly comprises an upper pull rod and a lower pull rod, a longitudinal counter bore is formed in the lower end of the upper pull rod, inner threads are arranged in the longitudinal counter bore, outer threads are arranged on the periphery of the lower pull rod, the upper pull rod and the lower pull rod are connected to form a whole through the threads, a first transverse through hole and a second transverse through hole are transversely formed in the bore wall of the longitudinal counter bore in the radial direction, the center line of the first transverse through hole and the center line of the second transverse through hole are both perpendicular to the center line of the longitudinal counter bore, and an included angle alpha is formed between the center line of the first transverse through hole and the center line of the second transverse through hole and is an obtuse angle. Grooves corresponding to the first transverse through hole and the second transverse through hole respectively are formed in the peripheral face of the upper end of the lower pull rod. When connection is carried out, transverse rods are inserted into the first transverse through hole and the second transverse through hole respectively, and one end of each transverse rod is inserted into the corresponding groove. The constant support and hanger is convenient to use and firm in connection.

Description

technical field [0001] The invention relates to a support and hanger, in particular to an anti-corrosion and wear-resistant constant force spring support and hanger. Background technique [0002] The constant force spring hanger is designed according to the principle of moment balance. Under the allowable load displacement, the load moment and spring moment are always in balance. For pipelines and equipment supported by constant force spring hangers, when displacement occurs, it can provide a constant supporting force, so it will not bring additional stress to pipeline equipment. Constant force spring supports and hangers are generally used in places where displacement stress needs to be reduced, such as power plant boiler bodies, suspension parts such as steam, water, smoke, air pipes and burners in power plants, and such supports are required in petroleum and chemical industries. The place. [0003] A traditional constant force support and hanger includes a housing, a p...

AI Technical Summary

Problems solved by technology

[0003] A traditional constant force support and hanger includes a housing, a pull rod assembly, a locking device and a load assembly. The load assembly is arranged vertically, and the load assembly includes a pull rod, which is an integral component. The constant force support hanger of this structure cannot be adjusted in length because the pull rod is an integral component, so it is inconvenient to use
