摘要： A hydraulic control system for use with double-acting shifting rams in a mine working.The system has a pump for supplying pressure fluid and main and return feed lines or conduits connected to the pump and laid along the working. An adjustable pressure-regulating device or devices serves to provide fluid at variable pressure in a further feed line or conduit.Each ram has its working chambers connected to a control device which is in turn connected to the main and further feed lines or conduits and to the return line or conduit. The devices can each be set to various positions to operate the rams in order to extend one of the rams its associated device is set to connect the working chamber used for extension (having the larger piston working surface area) to the further feed line or conduit, and to connect the other working chamber used for retraction (having the smaller piston working surface area) to the to the main feed line or conduit. With the aid of the pressure-regulating device or devices the force of the ram can then be controlled.

摘要： A longwall mineral mining installation has a conveyor and a plurality of roof support units positioned side-by-side on the goaf side of the conveyor. Each roof support unit has a roof shield having an advanceable shield extension. Each unit has a first hydraulic ram for extending its shield extension, and a second hydraulic ram for advancing the conveyor. The extension of each first ram is controlled in dependence upon the retraction of one of the second rams (either the second ram of the same unit or that of an adjacent unit). This control is effected by controlling the supply of pressurized hydraulic fluid to the first rams. In one embodiment this is carried out by a control valve which has a spring-loaded plunger which engages with a series of equispaced cams on the movable cylinder of the associated second ram. In another embodiment, the piston rods of the rams are provided with series of equispaced magnets. The cylinders of the rams are provided with sensors, which sense the magnets and generate control signals. A control box is provided to direct the control signals to control valves associated with the rams, so that the first rams are extended by the same distance as that through which the second rams are retracted.

摘要： A hydraulic control system, particularly for controlling the operation of roof support props of a mine working, employs control devices operated manually to feed pressure fluid to the working chambers of the props to effect extension or retraction thereof. A two-state valve device is operated when the props are extended to ensure that the correct setting pressure is established. This valve device has a control piston which is actuated to cause the device to establish independent connection between the main fluid pressure line and the associated working chambers of the props charged with fluid by the initial operation of the control devices. The connection established by the valve device is maintained even if the control devices break connection between the chambers and the pressure line. When the correct setting pressure is reached, a further control piston of the valve device is actuated to break the connection established by the valve device ready for the next operative cycle.

摘要： A roof support unit for a longwall mineral mining installation has a roof shield supported above a floor sill. A first hydraulic ram is provided for advancing the roof support unit. The roof shield is provided with a forward extension which is advanceable by means of a second hydraulic advance ram. A hydraulic control arrangement, which includes the two hydraulic advance rams is provided for controlling the advance of the roof shield extension in dependence upon the working stroke of the first hydraulic advance ram. The control arrangement is such that the amount of hydraulic fluid supplied to one of the pressure chambers of the second hydraulic advance ram is dependent upon the amount of hydraulic fluid expelled from one of the pressure chambers of the first hydraulic advance ram during the working stroke of the first hydraulic advance ram.

摘要： A hydraulic coupling device is connected to a multi-line hose comprising a plurality of hydraulic lines housed within a flexible sheath. The coupling device comprises a cylindrical nut, a plurality of plug pins housed within the nut, and means for holding the plug pins within the nut. The plug pins are each connectible to a respective line of the hose. The holding means comprises a holding disc, a retaining disc, and a sleeve. The sleeve is connected to the sheath of the multi-line hose. Each of the plug pins is provided with a pair of longitudinally-spaced collars which define therebetween a peripheral groove. The retaining disc is provided with a respective aperture for each of the plug pins. Each of the apertures has a diameter which is slightly greater than the diameter of one of the collars of the associated plug pin. The holding disc is provided with a plurality of radial slots. The peripheral groove of each plug pin engages within a respective radial slot of the holding disc. The collars of each plug pin are positioned on opposite sides of the holding disc, thereby limiting relative longitudinal movement of that plug pin relative to the holding disc. Said one collar of each plug pin is positioned within the associated aperture of the retaining disc.
