Description

A spring support and hanger testing device

Technical Field

The utility model relates to the technical field of spring support and hanger testing, in particular to a spring support and hanger testing device.

Background Art

The spring hanger is designed based on the principle of moment balance. Within the specified load displacement range, the load moment and spring moment are always balanced. Therefore, when the pipelines and equipment supported by the constant hanger are displaced, a constant support force can be obtained, and no additional stress will be brought to the pipelines and equipment. The constant hanger is generally used in places where displacement stress needs to be reduced, such as the boiler body of a power station, the suspended parts of the steam, water, smoke and air ducts and burners of a power plant, as well as petrochemical equipment and other places where displacement stress needs to be reduced.

At present, spring supports and hangers need to be inspected after production is completed, such as a detection device for a constant force spring support and hanger disclosed in Chinese patent application No. 202320821617.4. This patent relates to the technical field of constant force spring supports and hangers, and discloses a detection device for a constant force spring support and hanger, including a detection device, the detection device including: a base, on which a main shaft is arranged; a support frame, symmetrically arranged above the base and on both sides of the main shaft; a pressure sensor, arranged at the bottom end of the main shaft; a rangefinder, arranged on the other outer side of the lifting rod relative to the main shaft; a data recorder, arranged above the support platform; a constant force spring support and hanger, arranged on the base; a spring, arranged inside the constant force spring support and hanger; a support column, arranged at the bottom of the spring; a hanger connection structure, arranged at the top of the spring. At the same time, the device greatly improves the stability of the constant force spring support and hanger during detection by adding a fixing device to stabilize the positive force on the constant force spring support and hanger to be detected and adding a parallel sliding device.

Although the above patent can greatly improve the stability of the constant force spring hanger during detection by adding a fixing device to stabilize the positive force on the constant force spring hanger to be tested and adding a parallel sliding device, in actual use, the fixing device in the patent is relatively complicated, which makes its production and subsequent maintenance costs high, and the adjustment range of the fixing device is small, which makes it impossible to position some large-sized spring hangers, and thus makes it impossible to test them, thereby reducing the practicality to a certain extent.
