Vertical constant force spring hanger

Abstract

The invention discloses a vertical constant force spring hanger which comprises a horizontally-arranged base. The base is cylindrical. The base is internally of a cavity structure. A spring pressing plate is sleeved with the base. The upper end face of the spring pressing plate extends upwards to be provided with a plurality of spring pressing columns. A pressing plate is arranged on the upper end face of the base. The lower end face of the pressing plate extends downwards to be provided with a plurality of sleeve columns. Spring holes are formed in the sleeve columns along the length direction. The spring pressing columns are arranged in the spring holes in a sleeved manner from bottom to top. A spring is arranged at the portion, above each spring pressing column, inside the corresponding spring hole. A middle plate is arranged at the upper end of the pressing plate. A suspension arm base is arranged at the upper end of the middle plate. A rotatable suspension arm is arranged on the suspension arm base. A connecting rod is connected to the lower end of the suspension arm. The connecting rod sequentially penetrates the suspension arm base, the middle plate, the pressing plate and the spring pressing plate from top to bottom. A locking nut is arranged at the portion, below the spring pressing plate, of the connecting rod.

Description

technical field [0001] The invention relates to a hanger, in particular to a vertical constant force spring hanger. Background technique [0002] The constant force spring hanger is designed according to the principle of moment balance. Under the allowable load displacement, the load moment and spring moment are always in balance. For pipelines and equipment supported by a constant hanger, a constant support force can be provided when displacement occurs, so that no additional stress will be brought to the pipeline equipment. The precision requirements are high, so the performance of the constant force hanger is difficult to control. In the existing technology, the patent number is: 201320486066.7, and the patent name is "seat type constant force spring hanger". Although its structure has good control performance, its structural shortcomings Still outstanding: 1. After a long time of use, due to the lack of spring force points and uneven force, the spring is deformed, the s...

For pipelines and equipment supported by constant hangers, a constant support force can be provided when displacement occurs, so that no additional stress will be brought to the pipeline equipment. The precision requirements are high, so the performance of the constant force hanger is difficult to control. In the existing technology, the patent number is: 201320486066.7, and the patent name is "seat type constant force spring hanger". Although its structure has good control performance, it has structural shortcomings. Still outstanding: 1. After a long time of use, due to the lack of spring force points and uneven force, the spring is deformed, the service life is short, and the replacement is frequent, which increases the cost; 2. The structure needs to be raised as a whole when replacing the spring , and then replace it, the operation is complicated and difficult, time-consuming and labor-intensive, and increases the cost
