Abstract
The invention relates to a device for sinking a vertical borehole, more particularly a shaft, an extraction borehole in a deposit body, or a foundation borehole in the ground, with at least one excavating tool for excavating material from the bottom of the borehole, with an at least one conveyance means arranged in the active region of the at least one excavating tool for conveying away from the borehole material excavated from the bottom, with a machine frame on which at least two bracing elements are arranged for locking the device in the borehole during boring, with at least one means for vertically raising and lowering the boring device in the borehole and with at least one drive for rotating the excavation tool.
Claims22
A drilling device for sinking a vertical borehole, including a shaft, an extraction borehole in a deposit body, or a foundation borehole in the ground, comprising:
- at least one excavating tool configured to excavate material at a bottom of the borehole;
- at least one conveying element, arranged in the active region of the at least one excavating tool, configured to discharge material excavated at the bottom out of the borehole;
- a machine frame on which at least two bracing elements for locking the device in the borehole during drilling are arranged;
- at least one element configured to vertically raise and lower the drilling device in the borehole, and;
- at least one drive configured to rotate the excavating tool
- wherein the element configured to vertically raise and lower the drilling device in the borehole is a strand-jack system comprising at least one jack unit with at least one cylinder and with at least one strand or a strand bundle per jack unit, said strand or strand bundle being connected to the machine frame.
