A drive station for a mineral mining installation employs a plough box containing a chain wheel around which a drive chain for a mineral winning machine, such as a plough, is entrained. The chain wheel is supported on a shaft rotatably supported by bearings in a casing or housing fitted to the plough box. An access opening in the plough box enables the chain wheel to be fitted onto or removed from the shaft and a collar of the casing engages on a fitting ring inside the opening which locates the plough box and the casing or housing. The ring has a radial projection which extends into a pocket adjoining the access opening and a pair of pins which employ strain gauges engage on the ring projection to provide electrical signals indicating the tension in the upper and lower runs of the chain.

Arrangement for determining the tension in a chain used in a mineral

A transfer station between a scraper-chain face conveyor and a scraper-chain roadway conveyor in a mine working has a frame for guiding the scraper-chain assemblies of the conveyor so that material discharges from the face conveyor to the roadway conveyor. The frame has a pair of spaced-apart side walls with identical connecting blocks fitted to their exteriors. The connecting blocks have pockets for receiving couplers and depressions which form bearing half-shells for a support for a drum around which the scraper-chain assembly of the roadway conveyor passes. The connecting blocks on each side wall can connect with connecting blocks of the drum support or with connecting blocks on an endmost ramp pan of the roadway conveyor so that the pan and the drum support can be interchanged in position.

Transfer station assembly for scraper-chain conveyors

Apparatus for determining the tension in a chain, for example, has a pair of bearings in a housing mounting a shaft for rotation. The shaft bears a chain wheel. The bearing nearest the chain wheel is fixed in the housing while the opposite bearing is fitted into a floating ring which bears on the ends of a pair of bolts incorporating strain gauges.

Apparatus for determining the tension in a chain or the like

A plough drive employs a plough box mounted face to face on a side plate or intermediate plate of a machine frame of a scraper-chain conveyor. A rotatable chain wheel is disposed in the box for driving a chain coupled to the plough. A chain stripper seats in a pocket in the box and is locked therein. The stripper can be withdrawn laterally from the pocket. The stripper is connected to an adjustable annular collar on the casing of a gearing unit which drives the chain wheel and is detachably secured to the side of the box remote from the frame. The gearing unit and stripper can thus be withdrawn together laterally from the box and the chain wheel can likewise be withdrawn laterally via an aperture in the side of the box remote from the frame.
