ASSEMBLY DEVICE Russian patent published in 2006 - IPC E21D13/04 E21D23/00 

FIELD: mining industry, particularly underground mineral mining, namely to connect powered roof support sections, to assembly lava conveyer and cutter-loader of component parts.

SUBSTANCE: device comprises base, rotary column and roof beam. Gripper pad is installed on the base. Rotary column is connected with telescopic boom by boom lifting hydrocylinder. End boom with load-gripping means is connected to the first end thereof. The device is also provided with hydrocylinders adapted to move and lift the device. The base has beams of box-type cross-sections, which may slide in side cavities of base frame by two moving hydrocylinders. The beams are pinned to holders provided on front beam ends and on upper plane of the base. Orifices for boom lifting hydrocylinder pinning are formed on both beam sides. Upper beam plane is used as support surface adapted to drive rollers secured in holders of the base during movement thereof.

EFFECT: increased speed of support section assemblage, possibility of autonomous assembly device movement inside assembly chamber of mine without auxiliary winch and puller usage and, as a result, reduced industrial injuries.
