Method for rectifying cushion block for supporting asphalt tank, and measuring tool

Abstract

The invention provides a method for rectifying a cushion block for supporting an asphalt tank. The method comprises the following steps: marking at least one position at each of four corners of the first surface of the cushion block as a measuring point; placing the cushion block on the bottom of the asphalt tank, and maintaining the distance between the cushion block and the bottom plate of the asphalt tank at a basic value H1; placing measuring tools at respective measuring points, and obtaining, by the measuring tools, the vertical distances H2 between the cushion block and the bottom plateof the tank at respective measuring points; subtracting the basic value H1 from the measured vertical distances H2 to obtain the thicknesses H required to be machined at the corresponding positions on the cushion block; milling the four corners of the cushion block according to the thicknesses H and inspecting the quality of the milled cushion block. The method can rapidly inspect the cushion block for supporting the asphalt tank, improves the labor efficiency of workers, shortens shipbuilding period, improves the technical level of the construction of a asphalt ship, and can reduce the rejection rate of the cushion block, reduces cost loss, and creates economic benefits.

Description

Technical field [0001] The invention relates to a method for correcting a cushion block used for supporting an asphalt tank and a measuring tool. Background technique [0002] The entire asphalt tank of the asphalt ship is in a suspended state, and the weight of the entire tank is supported by several supporting blocks in the enclosure. The medium transported inside the asphalt tank has a high temperature, and the tank body is heavy in contact with the supporting blocks. The quantity and area directly affect the stress status of the "ULEPSI" polymer thermal insulation support pad at the bottom. How to ensure that the contact number of the support pad and the overall contact area are obviously increased. [0003] After the asphalt tank is hoisted into the cabin, the original technology is to measure the number of internal diameter micrometers or vernier calipers, and then calculate the processing thickness of the support pads through conversion. After the support pads are installed,...

AI Technical Summary

Problems solved by technology

The main disadvantages of this technology are: the output accuracy of the support pad is not high, the amount of measurement data is large, some positions are dead angles, the measurement tools cannot be measured accurately, the speed of measurement data is slow, the efficiency is low, and the amount of rework is large; the support pad After installation, check the clearance height between the support pad and the bottom of the tank through the light transmission of the inspection rod, and cannot obtain effective data record analysis, cannot clearly and clearly judge whether the inspection is qualified, and cannot improve the effective data analysis for the later improvement of the project
