    摘要: A long-wall mining machine has an operating chain entraining conveyor flights or mining tools and displaceable in a trough which can be provided with rows of sensors of an inductive proximity type responding to the chain and the tools and generating measurement pulse trains which are compared with setpoint pulse trains to signal functional parameters of chain operation. The sag of the chain is determined by a row of sensors and in response to the sag a chain-tension unit can be controlled.

    摘要: Toggle securing device for toggle joints of conveyor pans for chain conveyors, guide pans of winning machinery guides and the like with a securing plate which secures the toggle in its receiving pocket, laterally overlaps it at the end, can be introduced from the side into a respective insertion pocket by its two ends and can be caught in one of the two superimposed insertion pockets by a plastic pin which passes through a receiving hole in one end region of the securing plate and penetrates a locking orifice in the associated insertion pocket. In order to provide a securing plate for toggle joints, which can be used for toggle joints of known designs, either using a fixing sleeve or using a plastic pin as a securing element, the securing plate has a drive-in hole for a fixing sleeve at its other end region and is designed in such a way that it can be caught on the locking orifice of the insertion pocket either by means of the plastic pin or by means of the fixing sleeve after being rotated through 180.degree..

    摘要: A retraction mechanism for drawing a plough drive chain into a chain channel of a coal plough guide built onto the side of a scraper chain conveyor comprises a retraction slide which can be drawn through the chain channel and guided. The plough chain is connected to the slide which, via a chain section and a chain claw can be connected to an external traction drive, preferably to the scraper chain assembly of the scraper chain conveyor, so that the mechanism can draw the plough drive chain through the chain channel. The traction chain incorporates an overload clutch which limits the traction force. The clutch has two complementary parts one of which has a detent ball pressed by a prestressed spring into a detent recess of the other clutch part, so that the clutch is closed. A releasable lock or fixing device secures the detent ball in its released position.

    摘要: A gearing unit has an input shaft coupled via a gear train and a clutch to an output shaft which can propel a drive chain for a mineral winning machine or plough.The clutch is released by hydraulic pressure and a load sensor operates a valve device to release the clutch should an excessive load occur. The response of the hydraulic system is optimised by using a special fast-switching valve device and by maintaining a certain pressure in a release chamber of the clutch by circulating pressure fluid through the valve device when the clutch connects the drive to the output shaft. This pressure is lower than that necessary to release the clutch and the valve device rapidly switches to increase the pressure should an overload occur.
