Problems solved by technology

[0020] A "lock the ground conveyor" button or switch must be installed on the console of the stacking crane to complicate the control circuit of the stacking crane
[0021] Due to the above-mentioned shortcomings in the existing interlocking protection technology of stacking cranes and ground conveyors, its use effect is still not ideal

Embodiment Construction

[0039]Embodiment of the present invention: all use signal transmission line (5) on the control signal input end of the program controller PLC system (2) of the control ground conveyer (1) operation of each section in the carbon block transfer station of existing production workshop Connect to a detection switch (3), the detection switch (3) can adopt inductive proximity switches, mechanical travel switches or various photoelectric switches sold on the market, so that the program controller PLC system (2) can receive After the detection switch (3) detects the signal of an object, it sends a locking signal to the ground conveyor (1) controlled by it, prohibiting the operation of the ground conveyor (1); and when the stacking crane (4) completes the work After leaving the top of the ground conveyor (1), the detection switch (3) returns to its original state because it has not detected the stacking crane, and the action signal of returning to the original state is sent to the progr...

Abstract

The present invention discloses a stacking overhead crane and ground conveyer interlocking protecting method. Said method includes the following steps: using detection switch to detect stacking overhead crane position over the ground coveyer which is controlled by program controller PLC system, transferring the action signal of detection switch to the program controller PLC system of working station to which said ground conveyer is belonged, according to said signal said program controller PLC system can lock said ground conveyer to stop its operation. All the í‹lockingíŒ and í‹releasingíŒ operations can be automatically implemented by PLC system.

Description

Technical field: [0001] The invention relates to a method and device for interlocking protection between a stacking crane and a ground conveyor, in particular to prevent the equipment from being damaged due to the false start of the ground conveyor when the stacking crane picks up and puts carbon blocks on the ground conveyor. The invention discloses a method and device for interlocking protection of stacking cranes and ground conveyors damaged by hanging collisions, and belongs to the technical field of interlocking protection of stacking cranes and ground conveyors. Background technique: [0002] At present, in the electrolytic aluminum production industry, there are carbon block transfer stations between the roasting, forming and assembly sections of the anode carbon plant to store and transfer the anode carbon blocks used or produced by each section. Each section has a carbon block conveyor running on the ground to enter the carbon block transfer station, and the transpo...
