For pipes and equipment supported by constant hanging, a constant supporting force can be provided when displacement occurs, so that no additional stress is brought to the pipe equipment. However, the existing detection device cannot effectively detect the performance of the constant force spring support and hanger, and the position stress influence of the constant force support and hanger is very easy to deviate during detection, so that experimental data are greatly influenced, and the detection effect is greatly reduced.
According to the constant force spring support and hanger spring elasticity detection device disclosed in the Chinese patent publication No. 215952908U, when the constant force spring support and hanger spring elasticity detection device is used, a spring to be detected is placed in a placing groove, then a rotary protective cover and the placing groove are closed, then a rotary buckle drives a rubber pad and the protective cover to be clamped, then a servo motor is started to drive a rotary disc to rotate, so that a short column drives the end part of a driving rod to rotate around the servo motor, the driving rod drives the driving rod to move back and forth in the placing groove, the driving rod drives a pressure sensor and a push plate to compress the spring back and forth, and accordingly data of the spring elasticity is obtained from the pressure sensor 5.
However, the device needs to take down the spring in the constant force spring support and hanger to detect the spring effect in the constant force spring support and hanger during the use, and the constant force spring support and hanger only needs to balance the spring force of the internal spring and the load force of the support and hanger to play the role of the constant force spring yellow support and hanger, and the device needs to be connected with a hanger at the tail end of the support and hanger to achieve moment balance for use during the actual use, so that the bearing force of the whole constant force spring support and hanger needs to be detected. The device can not measure the whole experimental data of the constant force spring support and hanger, and the spring is not effectively fixed during detection, and the form of the spring can be changed under the action of external force so as to influence the experimental data.
