Description

[0002] The constant force spring hanging device is widely used in the domestic and foreign energy industry, mainly applied to hanging the pipeline or equipment with large thermal displacement. Since the weight of the equipment is constant in the installation state and the working state, the output load of the constant force spring hanging device for hanging the pipeline or equipment is required to be constant. In theory, the load of the constant force spring hanging device is constant whether it is downward displacement or upward displacement. However, due to the manufacturing reasons and the long-term performance decline, there is a large deviation between the actual load and the design value of the constant force spring hanging device in the installation state, the working state and the conversion process from the installation state to the working state. Especially in the conversion process from the installation state to the working state, the actual output load of the constant force spring hanging device is in a changing state, and there is a large deviation between the actual load output value and the design value in the working state. The above load deviation value will increase the stress state of the equipment and affect the safe operation of the equipment. In addition, since the constant force spring hanging device is suspended in the air, it is difficult to accurately measure the vertical displacement.

[0003] In order to avoid the safety hazards caused by the load deviation of the constant force spring hanging device and facilitate the observation of the thermal displacement of the pipeline or equipment, an intelligent spring hanging device is needed to display the actual output load and displacement of the constant force spring hanging device in the installation state, the working state and the conversion process from the installation state to the working state in real time, so as to facilitate the real-time inspection and evaluation of the state of the constant force spring hanging device by the inspection personnel and provide a basis for accurate load debugging on site.
