Control method of electric drive of excavator bucket opening

FIELD: electrical engineering. SUBSTANCE: invention relates to electrical engineering and is intended for use on quarry excavators to improve the reliability of the excavator bucket opening mechanism when loading rock. In electric DC drive by means of setting device 17 angular speed setting equal to rated angular speed of electric motor is always set. In the initial moment of the drive operation, a restriction corresponding to the cable pulling current is installed in the controlled limitation unit 11. When control button 7 in unit 11 is switched on, maximum current limitation value is set. As a result, current and electromagnetic motor torque proportional to it increase sharply. This results in withdrawal of retainer 23 and opening of bottom 22 of bucket 24 of excavator. Current of armature winding 16 is increased up to value exceeding moment of resistance of mechanism holding retainer 23. Sharp reduction of load and, hence, current of electric motor is performed after pulling of retainer 23. Bottom 22 of ladle 24 opens under action of content and rock is unloaded. At that, electric drive only winds cable 20 on drum 19 at low load. When the current reaches the threshold level specified by threshold element 2, a constraint corresponding to the pull-up current of the cable is set in the controlled limitation unit 11. EFFECT: loading of excavator bucket bottom opening mechanism takes place only when retainer is pulled. 1 cl, 2 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 701 674 C1 (51) МПК E02F 9/20 (2006.01) E02F 3/43 (2006.01) E02F 3/46 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК E02F 9/20 (2019.05); E02F 3/43 (2019.05); E02F 3/46 (2019.05) (21)(22) Заявка: 2019100806, 10.01.2019 (24) Дата начала отсчета срока действия патента: (73) Патентообладатель(и): Общество с ограниченной ответственностью Компания "Объединенная Энергия" (RU) Дата регистрации: 30.09.2019 (56) Список документов, цитированных в ...

Control system for mining machine

A mining machine (100) such as a mining shovel includes a digging assembly (130) having an upward extending boom (122) and a dipper arm (134) generally horizontally supported by the boom (122) and configured to crowd toward and retract from a vertical bank (104) at a mine site. To determine if the dipper assembly (130) strikes the bank (104), an electronic controller (200) can calculate a calculated crowd force (272) based in part on a crowd motor torque (266) associated with a crowd motor (162), a crowd speed (264) of the dipper assembly (130), and an inertia parameter (274). If the calculated crowd force (272) exceeds a predetermined first crowd threshold (282), the electronic controller (200) can register an impact event (284). In further aspects, the electronic controller (200) can execute a force modification function (290) to modify the crowding forces and a speed reduction function (300) to reduce the crowd speed.

MOTORIZATION ASSEMBLY CAPABLE OF DEPLOYING A TRACTION FORCE, IMPLEMENTATION OF THE ASSEMBLY FOR THE MOTORIZATION OF AN ARTICULATED ARM AND ASSOCIATED METHOD

L'invention concerne un bras articulé comportant un premier membre relié par une articulation pivotante autour d'un axe à un deuxième membre, ledit bras articulé étant motorisé par un ensemble de motorisation comportant : - au moins deux dispositifs moteurs, - chaque dispositif moteur étant monté sur le premier membre et comportant une sangle de traction inextensible reliant un point d'attache sur le premier membre à un point d'attache sur le deuxième membre, - chaque dispositif moteur comportant au moins deux moyens pousseurs configurés pour exercer une poussée transversale sur la sangle de traction inextensible, et - un organe de commande apte à faire fonctionner les moyens pousseurs des dispositifs moteurs selon une séquence prédéterminée, la tension exercée sur les sangles inextensibles permettant le pivotement du deuxième membre autour de l'axe. The invention relates to an articulated arm comprising a first member connected by an articulation pivoting about an axis to a second member, said articulated arm being motorized by a motorization assembly comprising: - at least two motor devices, - each motor device being mounted on the first limb and comprising an inextensible traction strap connecting an attachment point on the first limb to an attachment point on the second limb, - each motor device comprising at least two pusher means configured to exert a transverse thrust on the inextensible traction strap, and - a control member capable of operating the pusher means of the motor devices according to a predetermined sequence, the tension exerted on the inextensible straps allowing the pivoting of the second member around the axis.

Dragline excavating machine with direct drive hoist

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.

Controlling a digging operation of an industrial machine

Systems, methods, devices, and computer readable media for controlling a digging operation of an industrial machine that includes a dipper and a crowd drive. A method includes determining an acceleration associated with the industrial machine, determining a crowd retract factor based on the acceleration, comparing the crowd retract factor to a threshold crowd retract factor, setting a crowd speed reference and a crowd retract torque for the crowd drive for a period of time based on the comparison of the crowd retract factor to the threshold crowd retract factor.
