Multifunctional device for measuring adhesion force between dredging cutter teeth and clay and optimizing cutter teeth

Abstract

The invention relates to the field of dredging engineering in a water conservancy project, and discloses a multifunctional device for measuring the adhesion force between dredging cutter teeth and clay and optimizing the cutter teeth. The multifunctional device for measuring the adhesion force between the dredging cutter teeth and the clay and optimizing the cutter teeth comprises a water tank, aloading mechanism, a consolidated soil sample box, a drawing soil sample box, a drawing mechanism, a drawing and pressing sensor, a computer control system and the like. In the process of testing, thedrawing force is measured through the drawing and pressing sensor, and the real-time data acquisition is realized through the computer control system. According to the multifunctional device for measuring the adhesion force between the dredging cutter teeth and the clay and optimizing the cutter teeth, soil samples of different strengths can be prepared, the tangential adhesion force between dredging cutter tooth metal test plates and the clay under different overlying load, different running speed, different materials and different roughness and under the condition of atmosphere or immersionenvironment can be measured, and the real-time acquisition of data can be realized; and through determination results of different factor combinations, and main factors affecting the adhesion force between the dredging cutter teeth and the clay can be identified and the best combination reducing the adhesion force can be determined so as to guide the research and development and manufacture of new dredging cutter teeth.

Description

technical field [0001] The application relates to the field of dredging engineering in water conservancy engineering, in particular to a multifunctional device for measuring the adhesion force between dredging cutter teeth and clay and optimizing the cutter teeth. Background technique [0002] Dredging works have existed since ancient times. With the passage of time, dredging equipment has developed from simple manual tools in ancient times to now being replaced by machinery, such as dredgers. With economic development and social progress, the development of dredging technology and equipment is faced with the requirements of energy saving and environmental protection. [0003] At present, trailing suction dredgers are mostly used for dredging soft clay, while cutter suction dredgers are more suitable for dredging hard clay. Regardless of the type of clay, due to its cohesion, it will adhere to the tooth surface of the cutter tooth, resulting in increased cutting resistance,...

Problems solved by technology

However, at present, there is still a lack of practical and effective measurement methods at home and abroad, usually relying on engineering experience to design dredging cutter teeth, which has great blindness

In order to make up for the limitations of theoretical analysis, for the independent research and development of new dredging cutter teeth, it is urgent to combine simple and easy adhesion measurement tests for analysis. The key technology is how to simulate how to adjust the dredging cutter teeth at a certain depth The materials, surface roughness and cutting speed of the cutting teeth are used to reduce the adhesion between the cutting teeth and the clay. From the underwater dredging cutting teeth and clay adhesion measurement test, a new type of cutting tooth is developed. No such device has been found so far. report
