Double-spring balancing type combined vibration damping support-hanger

Abstract

The invention relates to a dual-spring balance integrated damping hanger, which can uses small spring to produce large product, with better vibration resistance function and the shock proof function of damper. It can be used in the support device and the heat tube of fire power plant, oil and chemical industries, to replace the constant force spring hanger.

Description

Technical field: [0001] The invention relates to a dual-spring balanced combined vibration-reducing and damping support and hanger. The structural type not only has the function of a spring support and hanger, but also has good vibration-reduction and damping functions. Background technique: [0002] The spring support hanger is used for the suspension and support of the boiler body of the power plant and the steam, water, smoke and wind transmission pipelines of the power plant. It is also widely used in petroleum, chemical and other industries, and the damper is used for the spring support The system suspended or supported by the frame can eliminate various unexpected vibrations generated by the absorption system and play a role of safety protection. For a long time, the two products with different functions have been used independently in their respective scopes. [0003] However, with the needs of industrial development and the renewal of design concepts, the pipeline sy...

Problems solved by technology

[0004] In the spring manufacturing industry, two small springs with the same energy storage use much less material than one large spring, and the processing is simple. The larger the spring, the thicker the steel wire diameter is, and the hardness difference between the inside and the outside is large during heat treatment. It can be inversely proportional to the weight, but even so, the vast majority of manufacturers in the support and hanger industry only use larger springs or use the technology of large springs and small springs when producing large support and hangers (ITT, GB10181). As far as the author knows, a German company in the world has an example of using two springs of the same specification in parallel (single-turn frame). From the other side, it is reflected that the materials and production processes are the same, and the performance of each spring is relatively discrete, which is exactly the same. It is difficult to match the performance of the two springs. For example, the patent 200410065669.5 has the conditions to use two springs in parallel, but it is useless. Maybe the machining error is much smaller than the error of the spring performance.
