摘要： A multi-functional connector is arranged for connecting a functional drill element to a drill head, such as an extendable cylinder of a drill head. The multi-functional connector includes a first connecting element having a first receptacle, a second connecting element having a second receptacle, and a retainer element having a retainer opening. The first receptacle has at least two driving surfaces for transferring a torque in a first direction, the second receptacle has at least two driving surfaces for transferring a torque in a first direction and in a second, opposite direction, and the retainer element has at least one retaining section to prevent a movement of a second functional drill element relative to the second connecting element in a retracting position of the second functional drill element.

摘要： A cutter assembly for an undercutting machine for cutting a rock workface and a method of assembling a cutter assembly is provided. The cutter assembly includes a shaft mountable on the machine with one end extending from the machine, and a cutter device arranged in connection to the extended end of the shaft. The cutter device is connected releasably and rotationally rigid to the shaft with a locking arrangement. The locking arrangement includes a first locking device arranged to transfer substantially axial loads, and a second locking device arranged to transfer substantially radial loads.

摘要： The invention relates to an extendable cylinder (10), in particular an extendable cylinder for a drill head (2000), a drill head comprising an extendable cylinder, and a method of operating a drill head. The extendable cylinder comprises a shaft (100) with a shaft ring volume (101) between an inner part (110) and an outer part (120) of the shaft; a piston (200) with a piston ring volume (201) between an inner part (120) and an outer part (220) of the piston; the piston being moveable with respect to the shaft along a longitudinal axis (LX); a proximal end of the outer part of the piston being arranged between the inner and outer part of the shaft; and a distal end of the inner part of the shaft being arranged between the inner and outer part of the piston; and wherein the extendable cylinder is extendable and/or retractable along the longitudinal axis.

摘要： The present disclosure relates to an extendable apparatus, such as an extendable apparatus for a drill head, a drill head including an extendable apparatus, and a method of operating a drill head. The extendable apparatus includes a base section, a drive section, an extension section, and a functional section. The base section and the drive section are moveable with respect to the extension section and the functional section along a longitudinal axis. The drive section and the functional section are rotationally rigidly coupled to each other. The base section and the extension section are rotationally rigid coupled to each other, and the drive section and the functional section are rotationally moveably coupled to the extension section.
