METHOD OF TURNING AND MOVING LARGE SIZE EQUIPMENT IN UNDERGROUND LIMITED SPACES AND DEVICE THEREFOR

摘要

The invention is directed to provide turning and moving large size equipment in underground spaces. The technical efficiency is characterized in that equipment arranged on a platform is moved into a turning chamber, the platform is connected with a support beam by a traction rope via stationary block with a hoist and an expansion member, the support beam is fastened opposite a transport tunnel, then the hoist is actuated and turn the equipment to the moment when the longitudinal axis of the expansion element, the traction rope and the longitudinal axis of the platform make a straight line, then the hoist is disconnected, the platform is stopped in an intermediate position, the traction rope end is disconnected from the platform and the expansion element end is disconnected from the support beam, a fixing point of the stitionary block is changed and then the rope end and the expansion member are reconnected with the platform, thus making a next turn. Turn operation is repeated the required number of times to a full platform turn to 90°.
