Description
Technical Field
[0001] The utility model relates to the technical field of supports and hangers, in particular to an easy-to-maintain constant-force spring support and hanger. Background Art
[0002] The support and hanger is designed based on the principle of moment balance. Within the specified load displacement range, the load moment and spring moment are always balanced. Therefore, when the pipelines and equipment supported by the constant hanger are displaced, a constant supporting force can be obtained, and no additional stress will be brought to the pipelines and equipment. The constant hanger is generally used in places where displacement stress needs to be reduced, such as the boiler body of a power station, the suspended parts of the steam, water, smoke and air ducts and burners of a power plant, as well as petrochemical equipment and other places where displacement stress needs to be reduced.
[0003] The existing constant force spring hanger is mainly adjusted by the internal spring when in use. After the device has been used for a long time, the internal spring is easily damaged and cannot meet the use requirements. The spring needs to be replaced and maintained, but the existing maintenance method mainly adopts overall replacement, which increases the cost of use. Therefore, it is necessary to design an easy-to-maintain constant force spring hanger. Utility Model Content
