摘要:
A road milling machine having a milling roller with a plurality of chisels. A signal receiving unit is assigned to a machine component which is directly or indirectly involved in the milling process or to another machine component. The signal receiving unit detects an operating condition of the machine component and is connected to a signal emitting unit. An optical detecting device may be assigned to the road milling machine, whereby operations are made easier and the milling pattern is optimized.

A self-drilling connection anchor (10) includes an anchor tube (11), a drilling head (13) provided at the first end (12) of the anchor tube (11), an inner tube (15) arranged in the anchor tube (11) and having an interior space (16) for receiving an ejectable mass (30), a first axial, with respect to the longitudinal axis (L) defined by the anchor tube, opening (18) provided in a region of the second free end (14) that communicates with the interior space (16) of the inner tube (15), at least one outlet opening (20) provided in a region of the drilling head (13), and at least one second radial, with respect to the longitudinal axis (L), opening (19) provided in the region of the free second end (14) and communicating with the at least one outlet opening (20) via an intermediate space (17) formed between the anchor tube (11) and the inner tube (15).
摘要:
An adapter (21) for a self-drilling, chemically anchorable fastening element (11) is described, having a shank (12) with a first end (13) on which a drill bit head (16) is provided, and with a second, free end (14), the second end (14) of the shank (12) being provided with a threadlike outer profile (15). The adapter (21) which may be placed on the second, free end (14) of the shank (12) has an external engagement device on one end for a rotary tool receptacle of a drill which is to be used, a base section provided on the other end at a distance from the engagement means, and a hollow cylindrical connecting sleeve section which connects the base section and the engagement device. The connecting sleeve section has a threadlike inner profile which corresponds to the threadlike outer profile (15) on the shank (12). The adapter (21) is formed by a first element part (22) and a second element part (32) which are detachably connected to one another via a clutch device (41).
摘要:
A separate drilling head has a distal end which contacts the material to be drilled, and a proximal end which is attached to a drive mechanism. The drive mechanism drives the separate drilling head into the material. The separate drilling head is forcelockingly secured in a thin-walled hollow anchor tube, and the separate drilling head includes a hard metal cutter element, and a substantially axially-oriented, axial stop shoulder at the proximal end that passes into a circumferentially closed, outer cone.

An adaptor for setting a self-drilling, chemically anchorable, fastening element (5) includes a rotor member (21) rotatably supported in the adaptor housing (36) and having at its opposite ends (23,25) respectively, a coupling section (24) for connecting the rotor member (21) with a drilling tool (8) for joint rotation therewith, and a coupling receptacle (26) for fixedly receiving a free end (6) of the fastening element (5). Support elements (52,53) are provided in one of two housing parts (41,51) for rotatably supporting the rotor member (21). Sealing elements (42), which are provided in another housing part (41), for a connection channel section (32) that connects a connection opening (37) in the housing (36) for the ejection medium (4) with a feeding channel (31) in the rotor member (21).
