摘要:
A method and device for drilling and setting adhesive anchor bolts close to the mine face during the cutting operation of a tunneling or mining machine which is capable of being displaced on a traveling mechanism and includes a cutting cylinder or cutting head rotationally mounted on a cantilever arm pivotable in a vertical direction, and optionally in a horizontal direction. The method is carried out in a manner where the substantially horizontal forward movement of the cantilever arm at break-in cutting is detected and a signal is generated during break-in cutting to block commencement of a working cycle for drilling and anchoring. A controller (16) for excavation of material on the mine face is networked with a controller (15) for actuation of the anchor drilling and setting device (10) via radio, electrical or optical lines (17).

In a track chain running gear (2) for mining machines (1), in particular heading machines, including at least one running gear case (5) and a track chain running around the running gear case (5) and formed by a multiplicity of chain links (3) articulately connected to one another, the running gear case (5), on its side facing the roadway, carries sliding plates (6) that form contact surfaces for the chain links (3) running along them, wherein the chain links (3), on their sides facing the sliding plates (6), carry wear plates (7) whose projecting surfaces cooperate with the contact surfaces of the sliding plates (6). In a chain link (3) for a track chain running gear (2), the chain link (3), on its side facing the sliding plates (6) of the running gear case (5), carries wear plates (7) whose projecting surfaces cooperate with the contact surfaces of the sliding plates (6). In a method for producing chain links (3) of a track chain running gear (2) wear plates (7) are inserted into a casting die for the chain link (3), and the chain link (3) is subsequently produced by casting, wherein the wear plates (7) inserted in the casting die are cast around such that the wear plates (7) project beyond the surface of the chain link (3) after the casting procedure.

摘要:
A device for detachable electrical connection of a contact pin to a sheet metal component. According to this invention, a durable conducting connection of the contact pin to the sheet metal component may be achieved, whereby the sheet metal component has at least one perforation, in which a sleeve for a contact element is housed in an electrically-conducting manner, enclosing a spring element. The contact pin is housed in the sleeve by the spring element in the assembled position and the contact pin and the sleeve are electrically connected to the sheet metal component by the spring element. This arrangement has a particularly high current-carrying capacity as a result of the spring arrangement housed in the sleeve.
摘要:
A head or bottom element of a component support, having guide rails arranged side-by-side and aligned in an insertion direction for receiving a printed circuit board of a plug-in module, wherein the guide rails are formed by one-piece guide elements of the head or bottom element. The guide elements can be formed of two rows of several guide strips per guide rail, each of which extends in the insertion direction, which strips are punched out of a plate-shaped head or bottom element and are projectingly beveled in the direction toward an underside of the head element or a top of the bottom element. A distance of the guide strips of the guide rails is matched to the thickness of the printed circuit boards of the plug-in modules. The head or bottom element forms guide paths for the printed circuit boards of the plug-in modules between the rows of guide strips of the guide rails. The production of the head or bottom element is not only simplified, but is also made cheaper, and furthermore the possibility of contacting the head or bottom element with the printed circuit boards is increased.

A cooling arrangement with a housing for receiving electronic printed circuit boards or plug-in modules, and with an air-conditioning device which is connected via a coolant-conducting feed line and a return-flow line with at least one electronic component, to be cooled, on the respective printed circuit board or the plug-in module. The feed line is coupled with at least one component feed line assigned to the electronic component. The return-flow line is coupled with at least one component return-flow line assigned to the electronic component. The printed circuit board or the plug-in module has an area for fitting electronic components and a coupling area for coupling the feed line with the component feed line and for coupling the return-flow line with the component return-flow line.
