Groove wall gripper, method for operating groove wall gripper, and underground construction method
The invention relates to a groove wall gripper and a method for operating a groove wall gripper. The groove wall gripper comprises a support-type guide frame; a connecting device for suspending the groove wall gripper at the upper end region of the guide frame; and two gripper shovels arranged at the lower end region of the guide frame and each pivotable about shovel pivot bearings between an openreceiving position for receiving soil material and a closed position in which the gripper shovels rest against each other so as to enclose the received soil material. According to the invention, in order to pivot the gripper shovels, an inner shovel pivot bearing is arranged on at least one bearing carriage which is mounted on the guide frame so as to be displaceable between a lower carriage position and an upper carriage position; furthermore, the gripper shovels are each connected to the guide frame via at least one hinge bar.
本发明涉及一种槽壁抓夹器和一种用于运行槽壁抓夹器的方法，该槽壁抓夹器带有：支架式的引导框架；用于把槽壁抓夹器悬挂在引导框架的上端部区域处的连接设备；和两个抓夹器铲，其布置在引导框架的下端部区域处，并且相应可围绕铲摆动轴承在用于接纳土壤材料的张开的接纳位置与闭合位置之间摆动，在该闭合位置中抓夹器铲彼此贴靠，以便包围所接纳的土壤材料。根据本发明设置成，为了使抓夹器铲摆动，把内部的铲摆动轴承布置在至少一个轴承滑架处，该轴承滑架在下面的滑架位置与上面的滑架位置之间可移动地支承在引导框架处；并且，抓夹器铲相应经由至少一个铰接杆与引导框架连接。
