Description

Construction Machinery and Method for Controlling a Construction Machine The present invention relates to a construction machine to which a ground work tool in the form of a hydraulic or cable-type grab is attached or is to be attached, and a method for controlling such a construction machine. When performing civil engineering or other excavation work, for example, for the construction of foundation elements such as foundation piles or diaphragm walls, the specific control of the construction machinery used to perform these tasks (particularly those equipped with or intended to be equipped with ground work tools in the form of hydraulic or cable-type grabs) depends on the geological characteristics of the construction ground. For this reason, ground profiles are generally generated for the construction site, at least for larger construction projects. These ground profiles represent the layered structure of various types of ground that are distinguished from other types of ground in terms of the composition of ground materials, particularly in relation to structure, specifically physical properties. Ground profiles are generated to determine the ground profile of the construction site, for example, based on drill cores obtained through test drillings. Knowledge of the ground profile of the construction site is essential from an economic perspective, as the structure of the ground determines the cost of excavation. For example, excavation of construction sites with a high proportion of rock materials is more complex than that of sites with sand, gravel, and/or clay layers, as it proceeds slowly and results in greater tool wear. However, depending on the geology of the construction site, the ground profile can vary significantly even within locally limited areas. These variations generally consist of changes in the thickness of individual ground layers and changes in the rock horizon. In this invention, it is assumed that the physical properties of the ground, such as hardness, density, shear resistance (rolling), and cohesion, vary depending on the ground layer. Consequently, to optimize the processing of the soil layer, specific machine parameters that must be applied to construction machinery for the processing of construction work must be adjusted and appropriate values selected. Until now, these adjustments have been performed manually for each individual parameter. This is time-consuming due to the extensive adjustment options for actuation devices attached to or intended to be attached to construction machinery that can be used to insert ground work tools into the ground to be worked on, and requires the appropriate expertise and extensive experience of operating personnel to perform the best possible adjustments. Although there are support systems in construction machinery control systems that reduce the burden on machine operators and enable faster adjustment and control processes by automating monotonous or repetitive tasks through programs with predefined steps, certain processing operations cannot be fully automated and machine operators still need to make decisions. This is particularly relevant to grab aids (for hydraulic or cable grabs). Here, different parameters may need to be selected or applied for individual ground layers. These machine parameters, which the control unit of a construction machine applies to the operating unit to control the processing operation on the operating unit, include, for example, the drop height of the ground work tool, the closing cycle of the grab shells, the closing force of the grab shells, the closing speed of the grab shells, the degree of filling of the grab shells, the number of repetitions of the closing cycle, or, in the case of ground work tools such as hydraulic or cable grabs which may be drilling grabs, continuous basement wall grabs, or pile grabs, the number of drops. FIG. 1 is a perspective view of the construction machine of the present invention. In the following, the present invention is described in more detail using a preferred exemplary embodiment of a construction machine schematically shown in a single drawing. The construction machine (10) of the present invention according to FIG. 1 may have a mobile carrier device (12) having a crawler chassis as an undercarriage (14). An upper carriage (16) having an operator's cab (17) may be mounted on the undercarriage (14) so as to be rotatable about a vertical axis of rotation. A control device including an input device for the machine operator is preferably located within the operator's cab (17). A boom arm (18) can be articulated to an upper structure (16) so as to be pivotable about a horizontal axis. A retaining cable (24) equipped with deflection pulleys can be guided in the head (20) of the boom arm (18), and at the end of the retaining cable, a ground work tool (30) designed here, exemplarily as a cable grab (31), can be attached together with a grab frame (32) and lower grab blades (34).
