摘要: A coal plough has an elongate plough body which is provided with cutters at each end. The plough body is supported at each of its two ends, by a flat narrow skid on a plate of a plough guide. The skids constitute wear-resistant members and are connected to the plough body in a readily replaceable manner. The skids are so shaped that they guide the plough in the lower zone of the plough guide, and establish connection between the plough and the plough drive chain.

摘要: Mining apparatus comprises a longwall conveyor and tensioning means for tensioning the conveyor in its longitudinal direction. The tensioning means is constituted by a plurality of hydraulic tensioning rams, each of which is mounted, in use, by means of pivot joints at each end thereof directly between the conveyor and a respective roof support unit of a roof support assembly. Each tensioning ram extends at an acute angle to the longitudinal axis of the conveyor. The tensioning rams are positioned in two groups, one in each end zone of the conveyor.

摘要: A plough guide is composed of sections built onto the runs of channelling of a scraper chain conveyor. Behind a covering comprising covering hoods pivotable on joints, there are chain guide channels for the plough chain separated by spacers. Underneath each covering hood there is a robust guide beam which forms part of a lower guide for the plough. Each guide beam of solid rolled section is provided at each of its two ends with a recess into which is welded a stout bearing plate which on a level with the spacers. The bearing plates are equipped with open journal bearings for hinge pins positioned at the foot of the covering hood. The hinge pins are integral with hinge pieces, which are welded into recesses at the two ends of the covering hood.

摘要: The pans of a scraper-chain conveyor have a plough guide at one side. The pans are connected together at said one side with the aid of coupling pieces engaged in pockets in the side walls of the pans. Each coupling piece is pivotably fitted to a plate-like securing element which serves as a handle to enable the coupling piece to be inserted into or removed from the pockets. The securing element can be swung down into further pockets formed in the plough guide to lock the coupling piece in place.

摘要: A coal wining plough in a longwall working employs adjustable floor cutters mounted on curved carriers displaced in guideways on the body of the plough. Wedges abut on the upper ends of the carriers and are moved by hydraulic piston and cylinder units to set the position of the floor cutters and define the cutting level adopted by the plough. The units are operated with the aid of valves which respond to an electronic control device. Command signals from a remote control station are transmitted as by a radio to the plough to set up the electronic control device. Sensors on the plough provide electrical signals representing the position of the interface between the coal face and the floor and these signals are transmitted back to the control station. In a control sequence the plough runs along the seam and the sensor(s) provide signals relayed to the control station which also receives signals representing the distance moved by and/or the position of the plough. On a succeeding run the control station provides the control of the leading floor cutter in accordance with a control program.

摘要: A guide for mineral mining machines is composed of assemblies each secured to the mineral face side of a conveyor. The assemblies have angle plates secured to the side walls and structures formed with spacers separating upper and lower passages for a drive chain. Covers are detachably and pivotably mounted to the structures. The covers can be secured in a closed position covering the upper passage or swung outwardly to an open position on push-in hinge joints formed at their lower regions by interengaging components of the covers and the structures. The hinge joints have complementary projections and recesses which interengage when the covers are closed.

摘要: A mineral mining plough for use in asymmetric ploughing, and movable to and fro alongside a conveyor, has a plough body provided with cutter means at its two ends. A first cutter means is arranged to win material when the plough is on the uphill run (that is to say when the plough moves in the opposite direction as the conveyor). A second cutter means is arranged to win material when the plough is on the downhill run. The second cutter means is mounted on the plough body for vertical movement relative to the plough body. This enables the second cutter means to be swung out of its working position (on the downhill run) to lie in a rest position (on the uphill run) in which it is in the path of travel of the first cutter means. This vertical movement of the second cutter means results in a plough of shorter length than known asymmetric ploughs.

摘要: Apparatus is disclosed for controlling the position of a mineral mining machine such as a plough, movable along guide means such as a scraper-chain conveyor with a guide on one side. The apparatus employs piston and cylinder units coupled between the guide means and connecting devices pivoted to the guide means. A ball-and-socket joint is provided between each of the units and the associated connecting device.Elongate beams are interconnected at one end and are mounted via a head piece and a swivel joint to each connecting device. These beams are pivoted and guided at their other ends on roof support structures so that the units can operate to tilt the guide means about the pivot axes between the connecting devices and the guide means to thereby control the position of the machine.
