Description

Technical Field

[0001] The utility model relates to the field of constant force spring brackets, in particular to a constant force spring bracket. Background Art

[0002] Constant force spring supports are generally used for suspended parts such as steam, water, smoke, air ducts and burners in boilers and power plants, as well as places where such supports are needed in the petroleum and chemical industries, to avoid dangerous bending stress and adverse stress transfer in the pipeline system. Constant force spring supports are designed based on the principle of moment balance. Under the permitted load displacement, the load moment and spring moment always remain balanced. For pipelines and equipment supported by constant suspension, constant support force can be provided when displacement occurs, so no additional stress is brought to the pipeline equipment. When the thermal displacement of a suspension point in the pipeline system is greater than 12mm, it is advisable to use constant suspension to support it, so as to avoid dangerous bending stress and adverse stress transfer in the pipeline system.

[0003] There are various types of constant force spring brackets. The existing bottom-fixed constant force spring bracket needs to be installed and fixed with multiple sets of bolts to maintain the stability of the constant force spring bracket during use. However, when the constant force spring bracket needs to be replaced or removed for maintenance, it is inconvenient to install and disassemble, which will affect work efficiency. Therefore, we make improvements to this and propose a constant force spring bracket. Utility Model Content
