摘要： 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.

摘要： A scraper unit for a scraper-chain assembly is composed of a scraper and a clamping strap which define beds for receiving one or more chain links. The clamping strap is fixed to the scraper with the aid of nuts and bolts and one or more pivot joints formed between the strap and the scraper ensure that when the nuts are tightened onto the bolts, the clamping strap pivots on the scraper to clamp the chain link or links into position.

摘要： The invention employs pressure and displacement sensors for the automatic monitoring and adjustment of the pre-tension of endless belts, in the form of chains or the like, which sensors determine the pressure in the cylinder space and the movement of the piston of the tensioning cylinder, and the measuring signals from which sensors are evaluated by an electronic evaluation and actuation unit. In this respect the evaluation and actuation unit calculates from the measuring signals the changes in pressure which occur over a predetermined partial stroke of the piston of the tensioning cylinder, wherein these changes in pressure reflect the state of tension of the chain belt. When the chain tension is incorrect, the evaluation and actuation unit can therefore control the tensioning cylinder so that the optimum chain tension is set automatically.

摘要： Apparatus for tightening and releasing nuts on screw-threaded studs to fit or release a cover on a pressure vessel employs several devices for subjecting each of the studs to tension to clamp the stud whilst the nut is rotated thereon. Each device has a passage for receiving one of the studs and a threaded sleeve engaged thereon. An hydraulic piston and cylinder unit subjects the sleeve to tensile force and likewise the stud coupled thereto. Also in the passage there is a sensor which has spring biased relatively movable components for engaging on a head of the stud and on a system of rods providing a reference. The sensor is suspended in the passage and provides an indication of the strain imposed on the stud by the hydraulic unit.

摘要： A mineral mining installation has a plough guided for movement along a scraper-chain conveyor. Roof supports are connected to the conveyor with the aid of shifting mechanisms which employ boom-type guide linkages designed to co-operate with a compact controller to adjust the tilt of the conveyor and the cutting horizon of the plough. The controller employs a plate-like guide block guided for up and down motion at the goaf side of the conveyor. An hydraulic piston and cylinder unit is disposed alongside the goal side of the conveyor and pivots a cranked lever to raise or lower the guide block. The guide block is coupled to a headpiece of an associated one of the boom linkages so that the motion of the guide block is transferred to the headpiece.

摘要： Apparatus for automatically inserting and removing screw-threaded elements into and from threaded bores of a pressure vessel to fit or detach a cover employs a screw-clamping device with a carrier ring supporting individual mechanisms for each screw-threaded element. Each mechanism employs a pair of parallel hydraulic piston and cylinder units with their cylinders supported for sliding on a flat surface of the carrier ring and their piston rods linked to a pressure bridge which brace on a shoulder of a screw-threaded sleeve fitted onto the associated screw-threaded element. The entire mechanisms is displaceably adjustable relative to the carrier ring predominantly in a radial direction relative to a common pitch circle for all the screw-threaded elements.

摘要： A mobile machine for use in opencast mining employs a chassis with endless tracks and the chassis has outriggers projecting laterally outwardly from the tracks. A hopper supported by one outrigger receives raw ore material excavated by another machine or machines. The raw ore material passes from the hopper to a screen arrangement with superimposed oscillating screens which sieve the material to separate the finer mineral ore product from the coarser spoil. The mineral ore product which passes through the screens is transferred by a multi-stage conveyor extending perpendicularly to the tracks to a separate conveyor laid on the floor of the working alongside a path of movement of the machine. The spoil is transferred with another conveyor to the inlet of a jib which extends laterally outwardly from the tracks opposite the hopper. The jib itself has a conveyor which transports the spoil along the jib which then discharges the spoil onto a dump.

摘要： The pans of a scraper-chain conveyor are interconnected with a dog-bone type connector which fits into laterally open shaped pockets in the side walls of the pans. A projection on one of the ends of the connector engages in a recess closed off from the side access while a projection at the opposite end of the connector is locked in place with a swivelled-in locking plate. The plate fits into compartments in the side wall of the associated pan. The plate carries a resilient pin at one end which fits into recesses in one of the compartments while the opposite end of the plate has a tongue which snaps into a recess in the base of the opposite compartment.
