Embodiment Construction

[0026] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] see figure 1 As shown, the present invention provides a grab level excavation control method of a dredger, comprising the following steps:

[0028] Step S1. Set the opening degree sensor and the depth sensor on the grab bucket of the dredger;

[0029] Step S2. Based on the opening degree sensor and the depth sensor, the bucket tooth movement position information of the grab bucket is obtained, wherein the bucket tooth movement position information includes the depth parameter and the opening degree parameter of the bucket tooth of the grab bucket;

[0030] Step S3. Based on the spatial motion model of the bucket teeth, calculate the motion position coordinates of ...

Abstract

The invention provides a grab bucket horizontally dredging control method and system for a dredger. The grab bucket horizontally dredging control method for the dredger comprises the following steps that bucket tooth moving position information of a grab bucket is obtained based on an opening degree sensor and a depth sensor; a bucket tooth moving position coordinate of the next moving state of the grab bucket is calculated based on a bucket tooth spatial movement model; and movement of the grab bucket is controlled based on the obtained bucket tooth moving position coordinate of the next moving state of the grab bucket. According to the grab bucket horizontally dredging control method for the dredger, the bucket tooth spatial state of the grab bucket is obtained through the opening degree sensor and the depth sensor, the bucket tooth moving position coordinate of the next moving state of the grab bucket is calculated and obtained through the bucket tooth spatial movement model, and according to the obtained coordinate position, an operator controls movement of the grab bucket, so that the horizontally dredging function of the grab bucket is achieved.

Description

technical field [0001] The present invention relates to the technical field of dredging engineering, and more particularly, to a control method and system for grab level dredging of a dredger. Background technique [0002] At present, for the horizontal excavation function of grab dredgers at home and abroad, there are not only SKK's mature hydraulic torque converter drive + disc brake system grab bucket tooth movement scheme, but also the inverter drive scheme being developed by universities. However, for some large grab dredgers with non-standard design and construction, they do not have the function of horizontal dredging, and special custom-made dredging operation control equipment is used. Large-scale equipment transformation is risky. [0003] Therefore, how to realize the visual display of the dredging trajectory in the virtual bucket tooth space of the grab bucket to guide the crew to manually complete the horizontal excavation construction process to improve the ex...
