Problems solved by technology

[0003] The laser deflection meter on the market, it uses the image sensor to directly receive the light signal to complete the deflection measurement, but the existing projection measurement system also has its shortcomings, mainly in the small measurement range, generally used as the PSD light receiving device of the light receiving device The length of the chip is only a few centimeters, and the cost of structural improvement to expand its measurement range is quite expensive, so the cost of this method is relatively high. Although it can meet the needs of field engineering, its unit price is as high as hundreds of thousands, and the frequency of use is very low.

Abstract

The invention discloses a device and method for detecting the deflection of a main engine of a marine diesel engine. The device for detecting the deflection of the main engine of the marine diesel engine comprises line fixing and pulling frames fixed to the two ends of an engine base of the main engine of the diesel engine, equal altitude blocks, a steel wire rope and a measurer, wherein a tensioner is arranged on one line fixing and pulling frame, a tension regulator is arranged on the other line fixing and pulling frame, one end of the steel wire rope is connected through the tensioner, the other end of the steel wire rope regulates the tension of the steel wire rope to a specified value through the tension regulator, then the deflection of the main engine of the marine diesel engine is measured, and whether the deflection of the main engine is within a control range is judged to detect whether the main engine meets requirements. The deflection of the main engine of the marine diesel engine is measured through the combination of the measurer commonly seen in the market, the tensioner and the tension regulator fixed on the line fixing and pulling frames, the two equal altitude blocks and the steel wire rope, detection accuracy is high, cost is low, and the device for detecting the deflection of the main engine of the marine diesel engine is suitable for being widely used by shipbuilding enterprises.

Description

technical field [0001] The invention relates to a ship detection device and method, in particular to a detection device and a detection method for detecting the deflection of a main engine of a marine diesel engine. Background technique [0002] The marine diesel engine is the heart of the ship, it is very important to the navigation and safety of the ship. The installation quality of marine diesel engines has always been the key point of concern for marine engineers. If the installation of marine diesel engines is not done properly, it will leave a safety hazard to the ship's navigation. [0003] The laser deflection meter on the market, it uses the image sensor to directly receive the light signal to complete the deflection measurement, but the existing projection measurement system also has its shortcomings, mainly in the small measurement range, generally used as the PSD light receiving device of the light receiving device The length of the chip is only a few centimeter...
