Description

Technical Field

[0001] The utility model relates to the technical field of spring hangers, in particular to a vertical constant-force spring hanger. Background Art

[0002] The constant force spring hanger is designed according to the principle of moment balance. Under the allowable load displacement, the load torque and spring torque are always balanced. For the pipes and equipment supported by the constant hanger, it can provide a constant supporting force when displacement occurs, so it will not bring additional stress to the pipe equipment. The constant force spring hanger uses the elastic force of the spring to support the object, but in actual operation, the spring of the constant force spring hanger will not only be subjected to vertical pressure but also to horizontal extrusion, causing the spring to be subjected to lateral displacement during actual use. Therefore, when the spring is compressed, the middle section of the spring is prone to bending and deformation in any non-vertical direction in the front, back, left and right, thereby affecting the accuracy of the vertical constant force spring hanger, and then causing the spring to be easily damaged due to extrusion and deformation during use, which is not convenient for long-term use of the constant force spring hanger, and when the spring needs to be replaced, it is difficult for workers to conveniently load and unload the spring hanger.

In addition, the outer side surfaces of the main spring 5 are slidingly connected to the inner side surfaces of the shell 3 and the side surfaces of the fixed column 6, respectively, which can effectively prevent the middle section of the main spring 5 from bending and deforming in any non-vertical direction when being squeezed, thereby improving the accuracy of the vertical constant force spring hanger, and the scale lines opened on the surface of the fixed column 6 are also convenient for workers to confirm the weight of the heavy object in real time. When the main spring 5 needs to be replaced, first remove the bolts between the shell 3 and the shell cover 10 and the limit plate 8, and then remove the shell cover 10, the limit plate 8, the fixed column 6, the movable plate 2 and the main spring 5 in turn, thereby effectively reducing the difficulty for workers to replace the main spring 5 and improving the efficiency of replacing the main spring 5.
