Description

Technical Field

[0001] The invention relates to a spring bracket, in particular to an intelligent spring bracket system with convenient load adjustment. Background Art

[0002] Spring supports are important load-bearing equipment for pipelines, tanks, valves, pumps and rotating machinery in power plants. Their load and displacement directly affect the safe operation of the equipment. Since spring supports do not require a large space for installation and suspension structure, spring supports are widely used. Due to their own structural characteristics, traditional spring supports often have skewed and stuck supports. When the load of the spring support deviates from the design value, it is usually necessary to rotate the support with simple tools to roughly adjust the load. Its disadvantages are as follows: (1) When the equipment supported by the spring support is not at the center of the support or horizontal thermal displacement occurs, the support of the spring support is very easy to become unstable and skew. Even if it is corrected, it will still be skewed after the working conditions change. (2) Due to its own structural reasons and small space, the load adjustment accuracy is low, and the adjustment is extremely difficult and inefficient. Especially when the load of the spring support is large, it is almost impossible to adjust it using traditional methods. (3) The spring bracket load is measured by attaching strain gauges. The measurement accuracy is greatly affected by temperature, humidity and the quality of the gauges, and the efficiency is extremely low. The spring bracket needs to be unloaded when the strain gauge is measured, but it cannot be unloaded when hot, so the hot load cannot be detected. Other on-site load detection devices are all for suspension hangers. Currently, there is no equipment to perform load detection on spring brackets on site, let alone spring brackets that can accurately monitor load and displacement in real time and rate the results.
