Spring hanger capable of improving output rigidity and design method thereof

Abstract

The invention discloses a spring hanger capable of improving output rigidity and a design method thereof. The spring hanger comprises an upper end plate, a cylinder, a lower end plate, a spring pressing plate, an upper spring, a lower spring, a hexagonal head bolt, a turnbuckle and a positioning pin, wherein the upper end plate is fixed at a top opening of the cylinder; the lower end plate is fixed at a bottom opening of the cylinder; the spring pressing plate is positioned in the cylinder; the upper spring is positioned between the upper end plate and the spring pressing plate; the lower spring is positioned between the lower end plate and the spring pressing plate; the lower end of the hexagonal head bolt penetrates through the middle part of the spring pressing plate to connect with theupper end of the turnbuckle; the lower end of the turnbuckle penetrates through the lower end plate to extend out of the cylinder; a lug plate is arranged at the top of the upper end plate; multipleholes are formed in the side wall of the cylinder; and the positioning pin penetrates through the holes to insert in a groove hole in the outer peripheral surface of the spring pressing plate. The spring hanger and the design method thereof can improve the output rigidity of the spring hanger under the preconditions of not changing spring materials and not increasing the spring diameter and the outer diameter, and can satisfy the mounting demands in narrow space. In addition, the spring hanger with nonstandard output rigidity can be designed through a method of combining the upper spring withthe lower spring, so that the design and manufacturing costs and time of the spring hanger with nonstandard rigidity are greatly saved.

Description

technical field [0001] The invention belongs to the field of mechanical equipment manufacturing, and relates to a spring hanger capable of improving output stiffness and a design method thereof. Background technique [0002] At present, some equipment or pipelines in the energy industries such as electric power and petrochemical industry need high-rigidity spring hangers to hang, and the outer diameter and diameter of the built-in springs are generally large, so it is difficult to manufacture; spring hangers with built-in high-rigidity springs still exist It cannot be installed in a small space and other problems, causing greater installation and production troubles. In addition, in industrial production, the inner spring is generally a standard part produced according to the corresponding sequence. If the stiffness of the required inner spring is not in the standard sequence under special circumstances, non-standard design and manufacture must be carried out, which greatly ...

Problems solved by technology

[0002] At present, some equipment or pipelines in the energy industries such as electric power and petrochemical industry need high-rigidity spring hangers to hang, and the outer diameter and diameter of the built-in springs are generally large, so it is difficult to manufacture; spring hangers with built-in high-rigidity springs still exist Unable to install in a narrow space and other problems, causing greater installation and production troubles

In addition, in industrial production, the inner spring is generally a standard part produced according to the corresponding sequence. If the stiffness of the required inner spring is not in the standard sequence under special circumstances, non-standard design and manufacture must be carried out, which greatly increases the manufacturing cost and time.
