Abstract: The present invention relates to the field of coal mine underground auxiliary transportation equipment, and particularly relates to an overhead monorail driving unit group realizing mechanical fast power distribution. The overhead monorail driving unit group realizing mechanical fast power distribution includes a rail, wherein the rail is connected with driving portions, carrying trolleys and a hoisting beam, the hoisting beam is disposed in a middle position of the driving portions and the carrying trolleys, and the driving portions, the carrying trolleys and the hoisting beam are connected through driving portion short pull rods, frame-shaped pull rods and driving portion long pull rods.

Abstract: The present invention discloses an anchor supporting intelligent device, belonging to the field of electromechanical devices for fully mechanized working faces. The device includes four parts of net supporting systems, anchoring systems, ground supporting systems and power and turning systems. The net supporting system is installed above the ground supporting system. The anchoring system is installed below a main beam and a middle main beam in the net supporting system through screws. The ground supporting system is installed below the main beam and the middle main beam in the net supporting system to provide support for the whole device. Two ends of the power and turning system are respectively connected with the main beam and the middle main beam in the net supporting system in a mode of pin connection.

Abstract: The present invention discloses electromechanical equipment integrating functions of anchor protection and supporting, including a suspension support system, a power system, an advanced support system, a subsidiary transport system and an anchoring robot system. The suspension support system is fixed on a top end of a coal mining tunnel through an anchor rod to provide support for the system. The power system is mounted at a tail end of a system main beam in the suspension support system. The advanced support system is mounted at a front end of the system main beam in the suspension support system. The subsidiary transport system is mounted on the system main beam in the suspension support system at a rear side of the advanced support system. The anchoring robot system is mounted on the system main beam in the suspension support system between the power system and the subsidiary transport system.

Abstract: A magnetic piston shoe pair for an axial piston pump and the motor includes: pistons, coil suites, piston shoes and a swash plate, wherein the interior of the coil suite is a closed coil; the bearing surface that the end surface of the swash plate abuts the piston shoe is provided with micro-molding holes; the micro-molding holes are hemispherical; the back surface of the swash plate is provided with a primary iron core and two secondary iron cores; the iron cores are wound with coil; the coil is connected to an external alternating current power supply. When the pump/motor is working, the coil is energized to generate a magnetic field, thereby adsorbing the piston shoe on the swash plate. Meanwhile, the coil suite generates an inductive magnetic field.
