A chain arm saw electrical control system

Abstract

The invention discloses an electrical control system for a chain arm saw, which relates to the field of electrical control systems. The electrical control system includes: a PLC control module, a chain speed pulse module electrically connected to the PLC control module, a swing arm angle encoder, and a walking speed pulse module. Module, swing arm speed pulse module and human-machine interface module, through the pulse signal induced by the chain speed pulse module, swing arm angle encoder, walking speed pulse module and swing arm speed pulse module, and under the logic operation of the PLC control module , calculate the linear velocity value of the chain and chain arm saw walking and the angular velocity value of the chain arm swing, and control the walking of the chain arm saw and the swing action of the chain arm through the PLC control module, provide compensation displacement, and control the chain arm saw to walk at a slow speed During the slow swing cutting process, the chain arm is always in contact with the cutting surface, and the chain arm realizes no dead angle feeding, which solves the dead angle problem in the stone cutting process, improves the stone yield, and avoids the waste of resources.

Description

Technical field [0001] The present invention relates to the field of electrical control systems, specifically referring to a chain arm saw electrical control system. Background [0002] The current orbital chain arm cutting machine, its control system adopts conventional low-voltage electrical components combination control, does not have programmable functions, so the circuit is complex and cumbersome, rich in functions, and upgradeable. In addition, all the current orbital arm sawing machines, there is no tool compensation, there is a problem of cutting dead angles, causing trouble to on-site construction, but also causing waste of resources. [0003] Moreover: the current chain sawing machine circuit control system used in mines is mainly controlled by conventional buttons and instrument electrical components, and the control function simply displays a single data, and the stone mine dust is large, the water vapor is heavy, and the button electrical components are easy to accu...

Problems solved by technology

[0002] The current track-type chain arm cutting machine, its control system adopts the combination control of conventional low-voltage electrical components, does not have programmable functions, so the circuit is complex and cumbersome, and the functions are rich and scalable.

In addition, all current track-type arm-type sawing machines do not have feed compensation, and all have the problem of cutting dead angles, which causes troubles for on-site construction and wastes resources.

[0003] Moreover: the chain sawing machine circuit control system currently used in mines is mainly controlled by conventional buttons and instrument electrical components. It is easy to accumulate dust or rust, causing failure and affecting the production efficiency of the equipment
