- Tool condition monitoring device for monitoring the wear condition of a mining tool or a group of mining tools, here in the form of individual reamers 112, groups of several scraper knives 115 and pairs of cutting rollers 118, which in this embodiment have a number of the individual mining tools or groups of mining tools has associated carrier parts.
- the carrier parts are from individual
- Excavation tools or groups of excavation tools structurally separate and spatially spaced and releasably connected to the cutter arms 106 as part of a frame assembly of the cutter wheel 103.
- the carrier parts are designed as intermediate plates 121, each assigned to a scraper 112, as one type of intermediate part, intermediate strips 124, each assigned to a group of peeling knives 115, as a further type of intermediate part, and carrier bolts 127 arranged between two cutting rollers 118.
- Fig. 2 shows in a schematic rear view on the one hand a section of the cutting wheel 103 in the area of a cutting arm 106 and on the other hand further components of the Tool condition monitoring device according to the illustrated embodiment. From the illustration according to FIG. 2 it can be seen that the reamers 112 arranged radially on the outside are connected to a frame structure 203 of the relevant cutting arm 106 via an intermediate plate 121 .
- the intermediate plate 121 is three, exposed in Fig. 2 shown pipe connections 206 of the tool condition monitoring device with a line connection boxes 209 of
- Tool condition monitoring device connected, which in turn via a hose 212 of the tool condition monitoring device with an interconnection box 215 of
- Tool condition monitoring device is connected.
- the or each interconnection box 215 in turn is connected via an encapsulated cable harness 224 of the tool condition monitoring device to a transmitting unit 230 having a transmitting antenna 227
- Tool condition monitoring facility in Connection by means of which signals from the tool condition monitoring device can be fed wirelessly via a radio link 233 to a receiving unit 239 of the tool condition monitoring device that has a receiving antenna 236 .
- the receiving unit 239 in turn is wireless or wired to a data processing unit 242 of
- FIG. 3 shows a perspective view of a section of the radially outer edge area of a cutting arm 106 of the cutting wheel 103 shown in Fig. 1. It can be seen from the illustration in Fig. 3 that the radially outer reamers 112, which are here made of multiple parts, in a direction of rotation of the cutting wheel 103 are designed in the shape of a circular arc, for example over a circular arc segment of about 90 degrees, and are connected via the intermediate plate 121 to the frame structure 203 of the
- a base plate 303 welded to the frame structure 203 is arranged between the intermediate plate 121 and the frame structure 203
- Line connection boxes 209 which is arranged in the illustration of FIG. 3 under a base plate cover 306 accommodates.
- the line hose 212 explained with reference to FIG. 2 is installed in a hose channel 309 to protect against external influences
- Fig. 3 there are a number of protruding in the direction of advance and approximately centrally on the front of the cutting arm 106 in
- Fig. 4 shows a perspective view of the mutually structurally connected as a unit, forming a reamer monitoring module arrangement of the intermediate plate 121, the pipe connections 206, the line connection boxes 209, the line hose 212, a
