Description

Technical Field

[0001] The utility model relates to the technical field of supports and hangers, in particular to an adjustable constant-force spring support and hanger. Background Art

[0002] Constant force spring hangers (hereinafter referred to as constant hangers) are designed according to the principle of moment balance. Under the permissible load displacement, the load moment and spring moment are always balanced. For pipelines and equipment supported by constant hangers, constant supporting force can be provided when displacement occurs, so no additional stress is brought to the pipeline equipment. Constant hangers are generally used in places where displacement stress needs to be reduced, such as the suspended parts of power plant boiler bodies, steam, water, smoke, air ducts and burners in power plants, as well as places where such support is required in the petroleum and chemical industries. When the thermal displacement of a hanging point in the pipeline system is greater than 12mm, it is advisable to use constant hangers for support to avoid dangerous bending stress and adverse stress transfer in the pipeline system.

[0003] The prior art has the following deficiencies: the prior art application number 201821742868.9 of “a constant force spring hanger” includes “a shell, a working spring is arranged in the shell, a plurality of fixed shafts penetrating the shell and communicating with the interior are fixedly arranged on one side wall of the shell, a movable shaft sleeve is connected to the inner thread of the fixed shaft, a hollow working shaft is fixedly arranged in the movable shaft sleeve, a transparent magnet sheet is fixedly arranged at one end of the hollow working shaft located inside the shell, a fixing plate for closing the hollow working shaft is fixedly arranged at one end of the hollow working shaft located outside the shell, a plurality of light sources are arranged on the other side wall of the shell, and a light sensor electrically connected to a control computer is fixedly arranged on the fixing plate and located inside the hollow working shaft”;

[0004] The fixing hole size of the fixed lifting ring of the above-mentioned equipment is usually fixed and difficult to adjust. It is often more suitable for fixing pipes of a certain diameter and is difficult to fix pipes of different diameters. The convenience of adjusting the size of the fixing hole of the fixed lifting ring of the constant force spring support hanger can be further improved. In addition, the fixed lifting ring of the existing constant force spring support hanger usually does not have a structure to buffer the force generated by the vibration of the pipe body when in use. The fixing bolts between the hanger and the fixed lifting ring are easily loosened due to the influence of the vibration force of the pipe for a long time, thereby affecting the installation stability of the fixed lifting ring.
