Disk spring hanger with three guide posts and limiting function

Abstract

The invention discloses a disk spring hanger with three guide posts and a limiting function, comprising a bottom plate, wherein the bottom plate is connected with the lower ends of the guide posts, a pressing plate is sleeved on the upper parts of the guide posts, the upper end parts of the guide posts above the pressing plate are in threaded connection with guide post nuts, a center hole is arranged in the central position of the pressing plate, a disk spring is arranged between the pressing plate and the bottom plate; the guide posts are in threaded connection with a limiting nut below the pressing plate, the pressing plate and the bottom plate are disk-shaped, the three guide posts are distributed uniformly along the circumferential direction. The invention has the advantages of capable of position limit in pre-operational test, material saving, low cost, and the like.

Description

technical field [0001] The invention relates to a variable disc spring support hanger, especially a disc spring hanger with three guide columns and a limit function, which is mainly used in the hoisting and fixing of industrial pipelines or equipment in electric power, chemical industry and other industries. Where there is thermal displacement in the vertical direction and the thermal displacement changes with the load. Background technique [0002] At present, hangers are often used to fix and lift industrial pipelines or equipment in industries such as electric power and chemical industry. The existing hanger structure has a base plate, which is connected to the lower end of the guide column, and the upper part of the guide column is equipped with a pressure plate. The upper end of the upper guide column is threadedly connected with a guide column nut, and a disc spring is arranged between the pressure plate and the bottom plate. The central parts of the pressing plate an...

AI Technical Summary

Problems solved by technology

For the hanger of this structure, since the pressure plate and the bottom plate are square plates, and the four guide columns are located at the four corners, under the same specification, the material consumption is large, the processing amount is large, and the cost is high; Most of the pipelines or equipment need to be tested by hydraulic pressure or overload before operation. At this time, no displacement is required. Since the existing hanger has no limit parts, displacement will inevitably occur during the hydraulic pressure or overload test. Experiments make a difference
