摘要:
A network infrastructure for mobile machines which are usable in explosive areas, having inherently safe participants and not inherently safe network participants the latter being arranged in pressure-resistant housings. The machine has at least one controller for actuating at least one not inherently safe participant. In order to provide a network infrastructure which avoids the drawbacks of the prior art, the machine has, outside the pressure-resistant housing for the first controller, at least one second, inherently safe controller for actuating at least one inherently safe participant, wherein the first controller forms a data distributor for a plurality of not inherently safe participants and the second controller forms a data distributor for a plurality of inherently safe participants, and wherein the first data distributor and the second data distributor are linked via an electrically decoupled data communication link.
摘要:
A method and apparatus for determining the position and/or situation of installation components of a mineral mining installation which has as installation components at least one face conveyor for removing mined material, one shield-type support for keeping a face open, pushing devices for pushing the face conveyor and the shield-type support in active operation, an extracting machine which can be moved along the face conveyor, and a drift conveyor, the position and situation of at least one installation component being determined by a measuring system having a detection unit with measurement sensor and the detection unit decoupled from the movement of the extracting machine, can be or is moved to and fro between two points of the guiding system along at least one installation component at the face such as, e.g. the face conveyor, by a separate guiding system 21; a mining installation relating to the same.
摘要:
A plug-in module for controllers of mobile working machines, having a housing, a connection plug, electronics boards and at least one plug socket for connecting actuators or sensors. The housing being formed by a box with a front, rear and side walls as well as a base plate comprising a cutout for the connection plug, and in that the electronics boards are forming a board box by connecting two end boards and two side boards, with the board box being arranged in the interior of the housing, and with the plug socket being mechanically coupled to the housing by a strain-relief clip.

摘要:
A control device (10) for electro-hydraulic support frames with a casing (11) accommodating a circuit, several plug-in connectors (20) accessible from outside the casing (11) for the connection of control leads, and with actuating control elements (13) connected to the circuit. The control elements (14, 15, 16, 17, 18) are grouped together in several exchangeable modules (27), accommodated in the casing (11), which are connected to the circuit and to each other by plug-in connecting elements (30) when installed in the casing (11). The modules (27) are exchangeable independently of each other. The operating keys of a keyboard (16) and/or an indicator unit (18) can be combined in one operating module (28), which can be removed from the casing (11). The actual control of the control device in the casing (11) and operation of the support frame is permitted to continue during the exchange of the operating module (28).
