In order to be able to determine the location and/or position of at least one plant component even in the case of a dynamic mineral mining process, the at least one detection unit (25) includes an image sensor, by way of which at least four object points (21), which are at a predetermined spacing to each other and are detectable within the optical wavelength range, of at least one measuring object (20) associated with one of the plant components, are detected. Using the evaluation system, the position and/or location of the plant component can be determined from the projection of the object points detected by way of the image sensor.
Intrinsically safe connection unit with a network interface for intrinsically safe appliances in explosion-risk areas, having a housing 14, a voltage supply connection 12, plug connection 11 for connecting an intrinsically safe appliance via a transmission cable, and a decoupling circuit. For allowing even a multiplicity of network subscribers to be connected in the explosion-risk area with less wiring complexity, a plurality of plug connections 11A, 11B of the same type are provided as network interface, each being preceded by a separate decoupling circuit, and the voltage supply connection 12 builds a central feed connection with separate supply cores 13A, 13B, 13C for each plug connection 11A, 11B, 11C, each having at least two plug contacts 21 for data communication and at least two plug contacts 22 for supplying power to the connectable appliances via the transmission cable. The invention relates also to a Controller and a network interface for use therewith.
The invention relates to plug-in modules for controllers of mobile working machines, having a housing (11), a connection plug (17), electronics boards (21, 22, 23) and at least one plug socket (25) for connecting actuators or sensors. In order to provide a plug-in module, being usable in onboard controllers of a mobile working machine and being also suitable for use with a wide variety of actuators or sensors, according to the invention, the housing (11) consists of a box with a front, rear and side walls (12, 13, 14) as well as a base plate (15) comprising a cutout (16) for the connection plug (17), and in that the electronics boards are forming a board box (24) by connecting two end boards (21, 23) and two side boards (22), with the board box (24) being arranged in the interior (19) of the housing (11), and with the plug socket (25) being mechanically coupled to the housing (11) by means of a strain-relief clip (30).
The invention relates to a shield canopy for a shield-type support for underground mining, comprising a canopy plate (2) and a supporting structure (5) being welded on below the canopy plate (2) and having a plurality of longitudinal spars which extend from a rear canopy region (1A) up to a front canopy region (1B). In order to provide a shield canopy which can be produced at less cost and with lower weight and at the same time has a higher bending resistance than the known structures, the invention proposes that at least two of the longitudinal spars consist of section struts (6; 16) which are provided with a top section flange (7; 17) and a web (9; 19) running perpendicularly to said top section flange (7; 17), and in that the canopy plate (2) and the section struts (6; 16) are angled upwards in the front canopy region (1B).
E21D 23/04 - Structural features of the supporting construction, e.g. linking members between adjacent frames or sets of propsMeans for counteracting lateral sliding on inclined floor
In the transfer station (10) according to the invention, a holder plate (19) is arranged on a carcass (16) of the drive (17) for the longwall conveyor in the transfer region between a longwall conveyor (12) and a drift conveyor (13) in the region of a drive (17) for the longwall conveyor, wherein the drift conveyor is connected to the longwall conveyor so as to perform limited pivoting motions relative to the longwall conveyor. Said holder plate is provided with a bearing holder (21), in which a special connecting channel element (22) of the drift conveyor (13) is mounted so as to move pivotably relative to the longwall conveyor (12) or the drive (17) thereof about a pivot axis (26) defined by the bearing holder (21). The design has the special advantage that the pivot bearing is easily accessible and must transmit only low forces that result substantially from the charging of the drift conveyor.
