Variable disc spring support and hanger correction device

Abstract

The invention discloses a variable disc spring support and hanger correction device. The variable disc spring support and hanger correction device comprises a top plate (7), a first supporting leg (8) and a second supporting leg (9), wherein the first supporting leg (8) and the second supporting leg (9) are vertically arranged on the two sides of the lower end of the top plate (7). The height of the first supporting leg (8) is smaller than that of the second supporting leg (9). An ejection mechanism (11) is arranged on the lower end face of the first supporting leg (8). A through hole (12) is formed in the center of the top plate (7). According to the variable disc spring support and hanger correction device, through the arrangement of the ejection mechanism, the supporting legs and the top plate which cooperate with one another, the deformation quantity of a variable disc spring set is adjusted conveniently and fast.

Description

technical field [0001] The invention belongs to the technical field of mechanical maintenance of electric power, petroleum, chemical pipelines and electrified railway catenary systems, and in particular relates to a variable disc spring support and hanger correction device. Background technique [0002] In electric power, metallurgy, chemical industry, petroleum and other industries, the suspension parts such as steam, water, smoke, wind, coal pipes and burners or other structures will generate displacement stress when heated and expanded during use. Influenced by the impact, it is necessary to increase the variable spring hanger for energy absorption, and its applicable load range is 200-500000N. [0003] The variable spring support hanger has many obvious defects: it is not only large in size, heavy in weight, and inconvenient to install and arrange; it is also difficult to supply super long and large spring materials; the production process is complicated, and the labor i...

Problems solved by technology

[0003] The variable spring support hanger has many obvious defects: it is not only large in size, heavy in weight, and inconvenient to install and arrange; it is also difficult to supply super long and large spring materials; the production process is complicated, and the labor intensity of workers is high; Inherent characteristics, thus resulting in an uneconomical product structure

During the adjustment process, the small-load variable disc spring hanger can be adjusted by adjusting the position of the limit screw to adjust the deformation of the variable disc spring group so that the force on the hanger is normal; however, for large-tonnage variable disc spring hangers Due to the large load under the boom (up to 50 tons), limited space and inconvenient operation, it is extremely difficult or even impossible to manually adjust the limit screw on site.
