Problems solved by technology

At present, there are few test devices and test methods for the static stiffness of pipeline supports, and there are the following limitations: 1. The general test device is only for testing specific sizes and types of pipeline supports, and is not universal; 2. The movement of the loading device Unstable and inaccurate test results; 3. It is not easy to install and disassemble, which is not conducive to mass testing

Abstract

The invention relates to a static stiffness testing device and testing method for a ship system pipeline support, comprising a main body frame, a loading device and a pipeline support and clamping device, the main body frame includes an upper fixing frame and a lower fixing seat arranged symmetrically up and down, and the The four guide columns at the four corners are connected; the loading device includes a screw, a sliding platform and a pressure head. The bottom of the sliding platform is connected, and the four corners of the sliding platform are socketed and connected with four guide columns, and slide up and down along the guide columns; the pipeline support and clamping device includes a tube support plate, a tube support gasket, a pipeline support and a The plate is arranged at the bottom of the pipeline, and the pipe support gasket is arranged on both sides of the pressure head to be symmetrical with the pipe support plate up and down, and connected by bolts. The invention is easy to operate, high in reliability and good in versatility.

Description

technical field [0001] The invention belongs to the technical field of water surface transportation, and in particular relates to a static stiffness test device and a test method of a ship system pipeline support. Background technique [0002] Pipeline supports are widely used in marine seawater systems, high-pressure air systems, and hydraulic system pipelines. The main functions are: 1. Support and fix pipelines; 2. Improve the vibration isolation performance of system pipelines and reduce pipeline vibration and noise. The static stiffness of the pipeline support refers to the ability of the support to resist deformation when it is under load. The static stiffness is an important index to measure the impact resistance and other mechanical properties of the pipeline support. At present, there are few test devices and test methods for the static stiffness of pipeline supports, and there are the following limitations: 1. Common test devices only test specific sizes and types ...
