Embodiment Construction
[0042] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the protection scope of the present invention can be more clearly defined.
[0043] like figure 1 Shown is a method for controlling the fine excavation operation of a high flatness grab ship foundation trench provided by the present invention.
[0044] Its specific technical solutions are as follows:
[0045] A control method for precise excavation of a foundation groove of a high-flatness grab ship, the method comprises the following steps:
[0046] 1) Check whether each control device is running normally during the test operation;
[0047] 2) The excavation positioning is realized through the plane positioning module and the tide level positioning module respectively;
[0048] 3) Underwater mud depth measurement is ...

The invention relates to a control method for the precise excavation operation of a high-flatness grab bucket ship foundation groove; the grab bucket crane installed at the rotation center of the crane is equipped with first positioning devices respectively installed on the top of the grab bucket crane to detect the real-time excavation position of the grab bucket. The second positioning device for the rotation angle of the swing arm and the coordinates of the rotation center, and the third positioning device for detecting the real-time position of the dredger and the angle of the ship installed on the top of the ship's bridge, so as to correspond to a plurality of sensors located at different positions. Realize the accuracy requirements of different positions; calculate the real-time elevation H of the current water surface of the ship in real time through the tide level positioning module, so as to accurately calculate the depth difference between the grab bucket and the mud layer below the water surface; The dredging operation is carried out according to the relationship, so that the dredging accuracy can be adjusted according to the corresponding depth deviation under different opening angles.
Description
technical field [0001] The invention relates to the technical field of grab ship control, in particular to a control method for the fine excavation operation of a high flatness grab ship foundation groove. Background technique [0002] Compared with other types of dredgers, the grab ship has the advantages of simple equipment, less wear parts of the dredger, and lower ship cost. However, the level of plane positioning, tide level positioning and excavation control during the excavation process of the grab dredger is still low, and the excavation flatness is poor. Therefore, it is urgent to improve the control accuracy of the existing grab dredger during the operation, so as to improve the flatness of the trench, reduce the waste of infrastructure excavation, and shorten the construction period. SUMMARY OF THE INVENTION [0003] In order to solve the above-mentioned defects and deficiencies in the prior art, the present invention provides a control method for the precise e...
