Description

Technical Field

[0001] The invention belongs to the technical field of load detection of hanging devices, and relates to a system and method for accurately detecting and debugging the load of a water-cooled wall hanging device. Background Art

[0002] Suspension devices (including constant force spring hangers, variable force spring hangers and rigid hangers, etc.) have been widely used in industries such as electricity and petrochemicals. Their actual load directly affects the service life and safe operation of the equipment. At present, the on-site load inspection of constant force spring hangers and variable force spring hangers is usually carried out by visually checking the theoretical load, and the inspection of the load of rigid hangers is usually carried out by roughly judging by manual shaking or attaching strain gauges to the hanger for load measurement and debugging. The traditional load debugging method relies on workers to directly debug the load adjustment nuts with the help of pipe clamps, etc. There is no dedicated system and method for on-site load detection and debugging, and there is no device for simultaneous detection and debugging of multiple sets of suspension device loads. Its disadvantages are as follows: (1) The theoretical load is visually inspected, and shaking the rigid hanger can only roughly judge the load, and the actual load cannot be accurately detected. (2) The measurement accuracy is greatly affected by temperature, humidity and patch quality when measuring with strain gauges, and the efficiency is extremely low. (3) The traditional method of adjusting the load of the hanging device is inefficient. Sometimes it takes several workers several days to debug a set. In particular, the design load of the furnace top header hanging device of the current mainstream 600MW and above units is usually tens of tons, which cannot even be adjusted using traditional methods. When forcibly using external force for debugging, it may even cause the load adjustment nut or the hanging rod thread to "slip", and the threaded hanging rod may break when it is excessively twisted. (4) When debugging multiple sets of hanging devices for the same furnace top header, since the actual loads of each hanging device affect each other, when debugging one by one, it is impossible to make the actual loads of each hanging device reach the design value at the same time. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and to provide a system and method for accurately detecting and debugging the load of a water-cooled wall hanging device.
