Abstract:

A swing drive assembly for use with a mining shovel having a frame rotatable relative to a base, wherein the swing drive assembly is fixed to the frame and engages a ring gear fixed to the base to rotatably drive the mining shovel frame relative to the mining shovel base. The assembly includes a swing girder having a top wall and bottom wall joined by a back wall. At least one strut having a top end extends upwardly from the top wall, and an attachment point is proximal said strut top end for fixing the swing drive assembly to the frame. At least one attachment point is proximal one end of the top wall, and at least one attachment point is proximal an opposing end of the top wall, wherein the girder is fixable to a mining shovel frame at each of the attachment points. Preferably, each attachment point is fixed to the mining shovel frame with at least one bolt. Most preferably, the swing girder is mounted to the frame, and hangs below the frame to engage the ring gear.

US Classification:

37396, 37401, 701 50, 318803

Abstract:

A dragline excavating machine includes a gearless direct drive AC drive motor for driving each of the hoist and the drag drums in the system. The gearless AC motor is driven using a digital system which receives AC power from the utility system rectifies the power using active front end circuits, and converts the resultant DC to a frequency controlled AC using an inverter circuit. The resultant AC signal is employed to drive the gearless AC motor, resulting in reduced harmonic distortion, unity or leading power factor, and increased efficiency, reduced operating costs, and reduced mean time between failure.

US Classification:

37445, 414726

Abstract:

A dipper assembly includes a dipper, a dipper door, ands a closure mechanism. The dipper door is pivotally linked relative to the dipper, and has a closed position in which the dipper door closes the open bottom. The closure mechanism has a lock position and an unlock position, and is fixed relative to the dipper and linked to the dipper door. In the lock position, the closure mechanism holds the dipper door in the closed position. In the unlock position, the closure mechanism allows the dipper door to swing away from the closed position.

US Classification:

91420, 91421, 91461

Abstract:

A crowd control mechanism for a power shovel includes an extendible dipper handle having an extended position and a retracted position. A double acting hydraulic cylinder having a an extendible ram has one of the cylinder and the ram fixed to the dipper handle and the other of the cylinder and the ram is stationary relative to the dipper handle. At least one of the cylinder and the ram have at least one of a blind end port and a rod end port, and at least one of the cylinder and the ram have the other of the blind end port and the rod end port, wherein hydraulic fluid flowing into the cylinder through the blind end port urges the ram toward an extended position to extend the dipper handle, and hydraulic fluid flowing into the rod end port urges the ram toward a retracted position to retract the dipper handle. Hydraulic fluid flowing into and out of the cylinder is controlled by one or more pilot operated poppet valves. A spool valve is disposed in a pilot line controlling at least one of the pilot operated poppet valves, and the spool valve controls the flow of fluid into the pilot line to control the at least one pilot operated poppet valve as opposed to a spool valve directly controlling the flow of hydraulic fluid into and out of the cylinder.

International Classification:

E02F003/04

US Classification:

037/411000

Abstract:

A mining shovel including a base and a frame rotatably mounted above the base. An upper member is fixed to the frame, and a lower member is fixed to said base. The lower member is engaged with the upper member to transfer horizontal forces between the upper and lower members, wherein the upper member is rotatably slidable relative to the lower member, and the lower member is axially slidable relative to the upper member. A bushing is interposed between said upper and lower members.

Inventors:

Carl D. Gilmore - South Milwaukee WI, US

International Classification:

E02F 3/30

US Classification:

414690

Abstract:

A crowd assembly () for a power shovel () includes a saddle block () adapted for pivotal connection to the shovel boom (). A tubular dipper handle () is slideably supported by the saddle block. A hydraulic actuator () has a cylinder () and a piston rod () that is outwardly extendable from one end of the cylinder. One of the cylinder or the piston rod is fixed to the dipper handle and the other one is attached to the saddle block. The cylinder and the piston rod are within the tubular dipper handle which is able to slide longitudinally over the cylinder. A guide bushing () extends around the one end of the cylinder and engages an interior surface of the dipper handle. The guide bushing thereby supports that end of the cylinder and inhibits hydraulic actuator from deflecting within the dipper handle when the piston rod is extended from the cylinder.

Abstract:

A sealed hydraulic tank system for a mining shovel () includes an upper tank () and a lower tank (). An air bladder () system is coupled to the upper tank to exchange air between the tank system and the bladder. The tanks include baffles () which filter the hydraulic fluid and which direct fluid flow along an elongated path to allow for de-aeration of the oil in the tank.

Abstract:

A mining shovel () includes a hydraulic system comprising a plurality of fixed displacement pumps () driven by a variable speed motor (), and a tank () system comprising an upper return tank and a lower supply tank (). A cylinder manifold () is connected to the pump control manifold (), and includes a directional control valve for directing the extend and retract functions of the cylinder (), while accepting fluid flow in a single direction from the pump control manifold. The single direction flow allows for the use of smaller fluid conduits (), such that the hose providing a high pressure supply can be comparatively smaller than the return hose ().
