摘要： A shield support, suitable for use in mines, comprising a floor-engaging structure which includes two sledge or like elements disposed side-by-side and spaced apart one from the other, a roof-engageable canopy, a shield mounted for pivotal movement with respect to the canopy and extendable and contractible prop means, carried by said elements, which are operable to adjust the height of the canopy. A pivotal guide linkage for supporting the shield from said elements includes links which are so connected to those elements and to the shield that the elements are rigidly coupled together only through the intermediary of those links and the shield.

摘要： A shield roof support has a sole plate, at least one roof or heel plate and a hydraulic element supporting the roof plate from the sole plate. The hydraulic supporting element includes a piston-cylinder actuator mounted inside the sole plate and extending along the longitudinal axis thereof, the movable element of the actuator being connected to one arm of an angle lever pivoted on a horizontal axis on the sole plate and having its other arm pivotally connected to the roof plate, the angle between the two arms of the lever preferably being adjustable. The lever transforms the force-action line of the actuator from the horizontal direction to the vertical direction. Thrust means on the longer arm of the lever are pivotally connected to the roof plate at a fulcrum, and a locking actuator is interconnected between the roof plate and the longer arm of the lever. A second piston-cylinder actuator extending longitudinally of the sole plate is operable to advance the sole plate relative to the working face of a mining operation, for example.

摘要： A roof support employs an hydraulic piston and cylinder unit as an adjustment device between the goaf shield and the roof-engaging structure. The cylinder unit is mounted to the shield with the aid of a bearing body defining a cup receiving a spherical end of the cylinder. The body also has recesses accessible via offset openings in which journals projecting from the cylinder are located. Locking pieces detachably fitted to the shield block the openings to retain the journals therein yet permit easy assembly and dismantling of the unit.

摘要： A mine support assembly is composed of separate floor-engaging sills each supporting one or more telescopic props and a goaf shield pivotably connected to a roof cap. The props can be extended or retracted to raise or lower the roof cap. The shield is divided into a common upper section and lower parts each pivotably connected to the upper section and to a respective associated one of the floor sills. Levers are pivotably connected between the sills and the upper section of the goaf shield and serve with the lower shield parts as a guide means ensuring the roof cap is raised or lowered without appreciable horizontal displacement. The floor sills and lower shield parts are respectively spaced apart and a shifting ram is connected to the floor sills via a transverse yoke pivotably connected to the forward end regions of the sills. The ram is located in a space between the sills and is connected at its rear end to a cross piece guided in the sills and connected to bars which extend along the space between the sills to form a cantilever beam connected directly or indirectly to a longwall conveyor.
