Description

Technical Field

[0001] The invention relates to a pipe support device in the field of shipbuilding, and in particular to a deformation measuring device and method for a PI type pipe support. Background Art

[0002] In order to further improve the acoustic stealth performance of ships, the newly developed PI pipe bracket has been widely designed and used in new products. As the main means to suppress the vibration transmission of system pipelines, the installation quality of the pipe bracket is particularly important.

[0003] The PI type pipe bracket adopts the structure of rubber pads and shock absorbers. Compared with the traditional elastic support, its structure has undergone significant changes. The original measurement tools and measurement methods are no longer applicable to the PI type pipe bracket. In order to ensure that the installation performance of the PI type pipe bracket meets the requirements of ship acoustic construction, it is urgent to detect the deformation of the installed PI type pipe bracket to ensure that its vibration reduction and isolation effect is maximized.

[0004] Therefore, how to measure the deformation of the PI-type pipe support while ensuring its installation quality and monitoring its use effect has become an urgent problem to be solved. Summary of the invention

[0005] In order to ensure that the installation performance of the PI type pipe support meets the requirements of ship acoustic construction, the present invention provides a deformation measurement device and method for the PI type pipe support. The method measures the distance between the lower edge of the lower clamp of the pipe support and the upper edge of the base twice to calculate the height deformation of the pipe support, thereby solving the technical problem that the deformation of the installed PI type pipe support cannot be detected.

[0006] The solution adopted by the present invention to solve the technical problem is: A deformation measuring device for a PI type pipe support comprises a magnetic base with a T-shaped structure design and a magnetic function at the bottom for providing installation and support; a digital telescopic ruler fixedly arranged at the upper end of the magnetic base; a rubber damper sleeved at the telescopic junction of the digital telescopic ruler; a limit screw assembled on the bottom side wall of the digital telescopic ruler for controlling the telescopic length thereof; a push pulley assembled on the side wall of the digital telescopic ruler and arranged on the upper part of the rubber damper; and a measuring ejector pin assembled on the top of the digital telescopic ruler.

[0007] In order to further solve the technical problem to be solved by the present invention, the present invention provides a method for using a deformation measuring device of a PI type pipe support, comprising the following steps: Step 1. Determine the rooting position and space of the pipe support, ensure that the welding of the base structure or angle steel of the pipe foot and the hull support structure for the rooting of the pipe foot is completed before the damping installation, and install the pipe support at the corresponding pipe foot. The pipe support is in an unfastened state and is not subject to external force; Step 2. Place the measuring device on the mounting pad of the pipe support, and make the magnetic base adsorb to the mounting pad, push the push pulley to move the measuring ejector pin upward, and when the measuring ejector pin moves to the lower clamp of the pipe support, control the measuring ejector pin to slide back and forth along its lower edge for calibration; Step 3. When the measuring pin is at the lowest point, tighten the limit screw, read the value displayed on the panel of the digital telescopic ruler, that is, the distance between the lower edge of the lower clamp of the pipe support and the upper edge of the base, and record it as the measured height H1; Step 4. Install the pipeline into the pipe support and tighten it effectively to ensure that the pipe support is installed tightly. After standing for 24 hours according to the technical requirements, read the value displayed on the panel of the digital telescopic ruler again, that is, the distance between the lower edge of the clamp under the pipe support and the upper edge of the base, and record it as the measured height H2; Step 5. Calculate the change in measured height ∆H=|H1-H2|, record it as the height deformation of the pipe support, and compare it with the rated deformation of this type of pipe support in the technical requirements. If the deformation exceeds the tolerance, an adjustment pad can be made and replaced at the adjacent pipe support to ensure that the deformation of the pipe supports on the system pipeline meets the technical requirements.

[0008] Positive effects: The present invention adsorbs a magnetic base on the installation pad of the pipe support, fixes a digital telescopic ruler on the upper end of the magnetic base, sets a rubber damper at the telescopic junction of the digital telescopic ruler, assembles a limit screw and a push pulley on the side wall of the digital telescopic ruler, and assembles a measuring ejector pin on the top of the digital telescopic ruler. By measuring the distance between the lower edge of the clamp under the pipe support and the upper edge of the base twice before and after the installation of the pipeline, the height deformation of the pipe support is calculated, and the deformation detection of the installed PI type pipe support is realized. This device is simple and convenient to operate, easy to disassemble and maintain, and avoids repeated measurement of deformation, thereby ensuring the installation effect of the PI type pipe support and effectively improving the efficiency of shipbuilding. It is suitable for use as a deformation measurement device and method for a PI type pipe support. BRIEF DESCRIPTION OF THE DRAWINGS
