An intelligent pitching hydraulic system and control method of an intelligent stacker-reclaimer

Abstract

The invention discloses an intelligent pitching hydraulic system and a control method for an intelligent stacker-reclaimer. The intelligent pitching hydraulic system includes a mobile phone and a computer cloud, a PLC control system, a hydraulic system and pipelines, an intelligent hydraulic fault diagnosis system, and an intelligent emergency automatic processing system. , the system includes the main control oil circuit for controlling the pitching mechanism of the stacker-reclaimer and the automatic switching backup oil circuit, and the accumulator storage backup function after power loss; the locking oil circuit for the pitching mechanism; the main control oil circuit for failure of the main pump and the control pump Oil circuit and locking oil circuit are automatically switched to control the oil circuit; hydraulic failure cannot automatically restore the automatic locking function of the faulty oil cylinder; fault analysis is fed back to the mobile terminal to facilitate data analysis and remote operation. The invention achieves the production requirement by remotely intelligently controlling the speed and the pitch angle of the pitch oil cylinder.

Description

technical field [0001] The invention relates to the field related to the pitching hydraulic system of a raw material stacker-reclaimer, in particular to an intelligent pitching hydraulic system and a control method of an intelligent stacker-reclaimer.

Problems solved by technology

[0002] The stacker-reclaimer is widely used in the raw material yards of mines, ports, steel mills and chemical enterprises to transport ore, coal, coke and other bulk materials. Wheel device, cantilever belt device, running device, slewing device, pitching hydraulic system, lubrication system and other parts, equipment operators can operate in manual, semi-automatic, and manual operation of the machine side unit, through the continuous development of the stacker and reclaimer At present, intelligent unmanned operation and intelligent remote operation have been realized. In the process of intelligent stacking and reclaiming, the hydraulic pitching system encounters problems and must be shut down to wait for processing. The equipment has been unmanned for a long time, and the specific failure phenomenon and failure point are not clear. It is necessary for the maintenance personnel to judge the problem and solve the problem before starting the automatic reclaiming, which will affect the production and operation of the whole unit. If the hydraulic system fails, no one on site will confirm and deal with it in time during the intelligent reclaiming process, resulting in serious accidents such as the rise or fall of the cantilever.
