Embodiment Construction

[0035] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the implementation of the present invention. example, not all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0036] With the continuous development of large-scale machinery and equipment mechanization and automation technology, fewer or even unmanned stackers and reclaimers is a future development trend, and the mechanization and automation of stackers and reclaimers is a necessary condition for realizing this trend. Against the background above, the present invention ...

Abstract

The invention discloses a stacker-reclaimer pitching hydraulic system, a close loop control system and a control method. The system comprises a main loop for controlling the stacker-reclaimer suspension arm pitching mechanism to move, a hydraulic control check valve control loop for providing inverse opening pressure to a hydraulic control check valve, and a manual control loop for supplying power to the system when the system is power-off or has fault. According to the stacker-reclaimer pitching hydraulic system, the close loop control system and the control method, the design requirement is achieved through controlling the speed of the pitching hydraulic cylinder and the vertical displacement of the suspension arm to make sure that the stacker-reclaimer can operate highly efficiently, stably and reliably.

Description

technical field [0001] The invention relates to the field of bucket-wheel stacker-reclaimer mechanical equipment, in particular to a stacker-reclaimer pitch hydraulic system, a closed-loop control system and a control method. Background technique [0002] The stacker-reclaimer is a track-type loading and unloading machine that uses the bucket wheel to continuously take materials and then uses the belt conveyor of the equipment itself to continuously stack materials. It is mainly composed of bucket wheel mechanism, slewing mechanism, pitching mechanism, cart traveling mechanism, tail car, belt conveyor and upper steel structure and other components; among them, the pitching mechanism of the stacker-reclaimer includes two types of mechanical and hydraulic, hydraulic The type pitching mechanism is widely used because of its small structure, flexible configuration, reliable operation, and convenient assembly. [0003] The schematic diagram of the connection between the pitching...
