Spring bracket allowing on-spot adjustment

Abstract

The present invention relates to field adjustable spring brackets. The top sliding pair is installed on the top of the bracket on the spring bracket, and the top sliding pair provides support for the pipe bracket and the pipe; the bottom surface of the upper bracket of the spring bracket is provided with a vertically downward lower sleeve, and the lower bracket of the spring bracket It is arranged under the upper bracket of the spring bracket, and the top surface of the lower bracket of the spring bracket is provided with a vertically upward upper sleeve, the lower sleeve is set on the upper sleeve, and the working spring is arranged in the upper sleeve. The upper end of the spring is pressed against the bottom surface of the upper bracket of the spring bracket, and the upper end of the working spring is pressed on the upper surface of the upper bracket of the spring bracket; the upper bracket of the spring bracket and the lower bracket of the spring bracket are adjusted by a load preload value adjustment mechanism Connected, the upper bracket of the spring bracket and the lower bracket of the spring bracket can move up and down relative to each other. The invention has simple structure, ingenious design, more reliable performance than similar spring brackets, more convenient construction and installation, and the actual working performance is more consistent with the design requirements, thereby ensuring the long-term safe operation of the pipeline.

Description

technical field [0001] The invention relates to supporting parts of a pipeline equipment supporting device, in particular to a field adjustable spring bracket. Background technique [0002] At present, in order to ensure the safe use of high-temperature and high-pressure pipelines and solve the problem of weight loss caused by the vertical displacement of high-temperature and high-pressure pipelines, spring brackets are generally used for high-temperature and high-pressure pipeline equipment brackets to support pipelines and meet the vertical thermal displacement requirements of high-temperature and high-pressure pipelines , but it mainly has the following defects: [0003] (1) The spring preload in the existing spring bracket must be completed in the equipment manufacturer, and the preloaded spring cannot be adjusted according to the site conditions at the construction site. [0004] (2) Due to the large deviation between the calculated weight of the pipeline design and th...

AI Technical Summary

Problems solved by technology

[0003] (1) The spring preload in the existing spring bracket must be completed in the equipment manufacturer, and the preloaded spring cannot be adjusted according to the site conditions at the construction site

[0004] (2) Due to the large deviation between the calculated weight of the pipeline design and the design position of the pipeline support and the construction environment on site, there is a large deviation between the calculated preload value of the existing spring bracket design and the preload value actually required on site, and there are potential safety hazards in pipeline operation

[0005] (3) Long-term operation of high-temperature and high-pressure pipelines and pipeline vibration during pipeline operation cause the spring in the spring bracket to lose part of the elasticity of the spring over time, and there are potential safety hazards in pipeline operation

[0006] (4) The spring preload in the existing spring bracket must be completed in the equipment manufacturer. Due to various reasons such as equipment transportation and installation, the positioning pin of the spring bracket is easy to fall off, and the spring bracket cannot be preloaded and restored on site. The construction only preloads the spring symbolically according to experience, so that the spring preload design value is quite different from the actual required preload value, and the pipeline has hidden dangers in safe operation
