Grab device and method for operating grab device
The invention relates to a method for operating a grab device with a carrier device and a rope grab arranged thereon, comprising a grab frame which is held on the carrier device via a holding rope, at least two grab shovels which are pivotably mounted at a lower end of the grab frame between a closed position and an open position, and an operating device, the invention relates to a carrier device having a handling rope for swinging a grab shovel, the handling rope being guided by the carrier device to a handling device, and the carrier device having a driven first rope winch for holding the rope and a driven second rope winch for handling the rope, wherein the carrier apparatus has a lower structure and an upper structure with a cantilever, which is rotatably mounted thereon about a vertical axis, on which the rope grab is mounted in a vertically adjustable manner, and wherein the rope grab is lowered into the soil by means of a holding rope with an opened grab shovel in order to form a groove in the soil in the removal step, in order to remove and accommodate soil material, the grab shovel is closed, the rope grab is pulled from the soil by means of the holding rope and swings into an emptying position by rotating the superstructure, where the grab shovel is opened to give accommodated soil material, and then the rope grab is moved back into the soil trough for repeating the removal step. According to the invention, a control device is provided, by means of which the rotation of the superstructure into the emptying position and the opening and closing of the grab shovel in order to give the soil material or the rotation of the superstructure from the emptying position back to the soil trough are automatically controlled.
本发明涉及一种用于运行带有载体器械和布置在其处的绳索抓斗的抓斗装置的方法，其具有抓斗框架，其经由保持绳索保持在载体器械处，至少两个抓斗铲，其在抓斗框架的下端处可摆动地支承在关闭位置和打开位置之间，和操纵设备，其带有用于摆动抓斗铲的操纵绳索，其中操纵绳索由载体器械引导至操纵设备，且载体器械具有用于保持绳索的经驱动的第一绳索绞盘和用于操纵绳索的经驱动的第二绳索绞盘，其中载体器械具有下部结构和带有悬臂的在其上可转动地围绕竖直轴线支承的上部结构，在其处绳索抓斗可竖直调整地支承，其中为了在移除步骤中在土壤中形成槽绳索抓斗以打开的抓斗铲借助于保持绳索下降到土壤中，为了移除和容纳土壤材料抓斗铲关闭，绳索抓斗借助于保持绳索从土壤拉动且通过旋转上部结构摆动到排空位置，在其处抓斗铲打开以给出容纳的土壤材料，且紧接着绳索抓斗为了重复移除步骤运动回到土壤槽中。根据本发明，设置有控制设备，利用其自动控制上部结构至排空位置的旋转和抓斗铲为了给出土壤材料的打开和关闭或上部结构由排空位置回到土壤槽的旋转。
