摘要： A roof support, suitable for use in mines, includes a roof-engageable canopy comprising a main portion and an extension portion pivotally-connected to the main portion. Actuator means is carried by the main portion and arranged to effect sliding movement of a wedge member. This member has a wedging face which is co-operable with a complementary face formed on a part of the extension portion which projects substantially beyond the pivotal connection of the extension portion to the main portion and in the direction towards the actuator means. The sliding movement of the wedge member effects tilting of the extension portion with respect to the main portion.

摘要： A roof cap assembly of a roof support mechanism includes a main cap having extension bearing portions at its front end, a forward cap which is pivotally attached at its rear end to the extension bearing portions of the main cap, and two supporting cylinders connected between the main cap and the forward cap at spaced apart locations across their widths and so as not to extend therebelow. The supporting cylinders include a housing containing twin pistons and an adjustable pressure transmitter is provided for each supporting cylinder and is constructed to increase the pressure in the pressure chambers therein when the pressure of the pressure medium supplied thereto exceeds a minimum set value.

摘要： A roof support, suitable for use in mines, includes a roof-engageable canopy which comprises a main portion and an extension portion having a pivotal connection to the main portion. Actuator means is carried by the main portion. A wedge member, which is operable by the actuator means, is disposed between, and is engageable with, the main portion and a part of the extension portion projecting substantially beyond the said pivotal connection towards the actuator means. The wedge member is adapted arcuately to be movable by the actuator means and such arcuate movement effects tilting of the extension portion with respect to said main portion.

摘要： To increase the height of operation of a shield type roof support an attachment is fitted to the floor sill or to each of a pair of spaced-apart floor skids. The attachment has side walls with bores for receiving pivot pins used to link the attachment to the floor sill or skid and to guide levers connected to the goaf shield. A transverse body extends between the side walls and defines a socket for forming part of a ball-and-socket joint connecting the attachment to a hydraulic prop. The side walls of the attachment have under surfaces which rest on a support surface of the skid or sill near the working face.

摘要： A roof support suitable for use in mines comprises a main roof-supporting structure, a cantilever carried by the structure, an actuator and a link member through the intermediary of which the actuator is connected to one end portion of the cantilever for moving the cantilever between retracted and extended positions. The end portion of the cantilever has projections which come into engagement with an abutment when, upon advancing movement of the actuator, the cantilever reaches its fully extended position. The abutment and projections are so shaped that when they are in engagement they form pivot means about which the cantilever can be tilted. The link member is so formed and so connected to the cantilever that upon further advancing movement of the actuator the cantilever is caused to tilt about the pivot means into a roof-supporting position.

摘要： A mine roof support has a main roof bar which is pivotably connected to an auxiliary forwardly-extendible bar. At least one piston and cylinder unit serves to swing the auxiliary bar about the main bar to bring the auxiliary bar into a roof-contacting position aligned with the main bar or into a stowed position beneath the main bar or into some intermediate position. One or more pivotable guide levers connect the auxiliary bar to the piston and cylinder unit. A guide member is also connected to the unit and slidably locates in longitudinal guideways formed in ribs or the like at the underside of the main roof bar.

摘要： A mine roof support unit has a mechanism for adjusting the angular position of an auxiliary cap relative to a main cap, the auxiliary cap and the main cap forming the roof cap of the mine roof support unit. The auxiliary cap is connected to the main cap by a first pivot joint. The cap-positioning mechanism comprises a hydraulic ram and a lever acting between the main cap and the auxiliary cap. The auxiliary cap is provided with an extension arm projecting from the first pivot joint towards the main cap. One end portion of the lever is connected to the arm by a second pivot joint, and the other end of the lever is connected to a block attached to the piston rod of the ram by a third pivot joint. The cylinder of the ram is attached to the main cap.

A piston and cylinder unit serves to swing the auxiliary bar about the main bar to bring the auxiliary bar into a roof-contacting position aligned with the main bar or into a stowed position beneath the main bar or into some intermediate position. Pivotable guide members connect between the main and auxiliary bars respectively and a pivot joint linked to the piston and cylinder unit.
