Tool for crushing coke

摘要

The invention relates to a tool for crushing coke, and includes a housing 2 that, in an operating state, is fastened to a drill rod, and in which is arranged at least one cutting nozzle 10 for cutting and a drilling nozzle 9 for drilling coke by means of a water jet, and a control for supplying water flowing through the housing 2 under pressure for drilling or cutting, wherein the control for switching the tool 1 from a drilling mode to a cutting mode and vice versa includes a control device 7 that is rotatable about a longitudinal axis of the housing 2 to switch the tool 1, wherein the drilling or cutting mode is set depending on the angular position of the control device 7. To obtain a clear understanding of whether the tool 1 is in drilling or cutting mode, at least one position element 38, 39 is arranged on the control device 7 that displays the angular position of the control device 7 in the drilling and/or cutting mode of the tool 1 through a window 18 in the housing 2.

1. A tool for crushing coke, comprising:
a housing (2) that, in an operating state, is fastened to a drill rod, and in which
at least one cutting nozzle (10) for cutting and a drilling nozzle (9) for drilling coke by a water jet, anda control for supplying water flowing through the housing (2) under pressure for drilling or cutting is arranged,wherein a control for switching the tool (1) from a drilling mode to a cutting mode and vice versa comprises a control device (7) that is rotatable about a longitudinal axis (A) of the housing (2) to switch the tool (1),wherein the drilling or cutting mode is set depending on angular position of the control device (7), wherein at least one position element (38, 39) is arranged on the control device (7) that displays the angular position of the control device (7) in the drilling and/or cutting mode of the tool (1) through a window (18) in the housing (2), wherein two position elements (38, 39) are arranged on the control device (7) that are different from each other and offset from each other at an angle, of which a first position element (38) is assigned to the display of the angular position of the control device (7) in the drilling mode of the tool (1), and a second position element (39) is assigned to the display of the angular position of the control device (7) in the cutting mode (1).
