Abstract

The invention provides a pile leg positioning pin hole grinding trolley and a grinding method thereof. The trolley is adsorbed to the inner surface of a pile leg positioning pin hole through adsorbing coils installed in front and rear driving wheels of the grinding trolley, the front and rear driving wheels rotate due to the adsorbing coils, a pressure adjusting coil on the lower portion of the grinding trolley is controlled through a control unit and a sensor so that pressure of a grinding wheel and pressure on the inner surface of the positioning pin hole can be adjusted and controlled all the time, a motor drives the grinding wheel to achieve grinding, and the grinding trolley is driven by the driving wheels to finish grinding the inner surface of the whole positioning pin hole. Full-automatic and high-precision grinding is achieved, labor is saved, production efficiency is improved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a trolley for grinding positioning pin holes of pile legs and a grinding method thereof. Background technique [0002] With the aggravation of energy shortage and the increasing shortage of wind farm land resources, offshore wind power generation has become a new direction for the development of wind power generation in the world today. Compared with the installation of onshore wind turbines, the installation of offshore wind turbines is more technically difficult. The wind power operation ship is the core technology of offshore wind farm construction. Realize the interaction between plugging piles, pile legs and seabed foundation, propping the hull out of the sea, and providing a stable working platform for offshore operations and wind turbine installation. Therefore, the construction of the pile leg structure is very important. In order to ensure the fit and posi...
