Abstract
The invention relates to an advancing tailpiece of a continuous belt conveyor system used in the mining industry. The advancing tailpiece is supported by telescopic booms extending from a support structure rising from the base of a tow car. The telescoping booms are pivotally connected to the support structure and the advancing tailpiece. The advancing tailpiece further includes a mechanical arm pivotally connected to the advancing tailpiece and having a telescopic boom. Carrying idler assemblies are loaded on the mechanical arm which is used to position the carrying idler assembly for attachment to an intermediate conveyor section of the continuous belt conveyor.
Claims14
An advancing tailpiece used in the mining industry, the advancing tailpiece to be supported by a support vehicle, the support vehicle having a support structure, the advancing tailpiece comprising:
- a frame;
- a means for positioning carrying idler assemblies within the frame, the positioning means includes a boom, the boom having a first end and a second end;
- means for angularly moving the boom through a horizontal plane and a vertical plane, the angular movement means coupling the first end of the boom to the frame;
- means for temporarily cradling a carrying idler assembly, the temporary cradling means located at the second end of the boom, whereby during advancement of the tailpiece, the boom is capable of movement to a first position, in which the temporary cradling means extends at least partially outside the frame to receive a carrying idler assembly, and through the vertical plane and horizontal plane to a second position, in which the cradling means extends within the frame and is lowered with respect to the frame.
