Simple emergent electrical control system of integrated excavator

Abstract

The invention relates to a simple emergent electrical control system of an integrated excavator. The simple emergent electrical control system is characterized in that an intelligent vacuum feeder switch is arranged on a control main path of the wire-incoming side of the integrated excavator, and simultaneously a spare gas probe is connected into the intelligent vacuum feeder switch; vacuum contactor attracting coils of an oil pump motor M1, a cutting motor M2 and a secondary conveying motor M3 connected into a control loop are respectively controlled by using a triple button, and the triple buttons use three closed button cores to respectively control start and stop of the three motors. The simple emergent electrical control system has the advantages that the principle is simple, the added equipment is more common in a mine institution, the performance is reliable, the site operation is easy, and the simple emergent electrical control system has basic protection functions. The simpleemergent electrical control system not only can be applied to EBZ260H type integrated excavators, but also can realize transformation on other types of integrated excavators in other manufacturers, and can meet the emergent use on site.

Description

technical field [0001] The invention relates to a simple emergency electric control system for fully mechanized excavators. Background technique [0002] The EBZ260H cantilever roadheader (remote control type) used in the mine is a new type of tunneling equipment with highly integrated and modular electrical control system, simple operation and remote control operation. The electronic control system of the fully mechanized excavator has relatively high technical content, especially EPEC controller faults and control circuit faults, which are difficult to find and deal with. Maintenance personnel need to have a high level of technology and take a long time to deal with them. In addition, the control system electrical Components are expensive. [0003] Once the electronic control system of the fully mechanized excavator fails to shut down during the cutting process, it cannot return to a safe place, which increases the safety hazards for maintenance personnel. In addition, d...

AI Technical Summary

Problems solved by technology

The EBZ260H fully mechanized excavator newly produced by Shanghai Chuangli provides an emergency remote control operation. The circuit of the emergency electric control system is complex, and it is necessary to ensure that multiple control power supplies and communication systems are intact. The most important thing is that it does not have basic electrical protection and gas protection. Electric lock and other functions
