Technical field:
The present invention relates to a kind of stacking overhead travelling crane and ground reclaimer interlocking protecting method and device; particularly a kind of when preventing that stacking overhead travelling crane from taking, putting the charcoal piece on floor conveyor; because of the floor conveyor error starting causes the bad stacking overhead travelling crane of hanging equipment clashing and breaking and ground reclaimer interlocking protecting method and device, belong to stacking overhead travelling crane and ground reclaimer interlocking protecting technical field.
Background technology:
At present, in the Aluminum Electrolysis Production industry, all be provided with charcoal piece transfer station between the workshop sections such as the roasting of its anode charcoal ink factory, moulding and assembling, to store and to transport the anode carbon block of each workshop section's production use or output.Each workshop section all has the charcoal piece conveyor of operation on the ground to enter charcoal piece transfer station, the carrying of charcoal piece in charcoal piece transfer station then mainly relies on the stacking overhead travelling crane that moves above the floor conveyor and carries out, and entering the conveyor of charcoal piece transfer station, each workshop section carries out interlocked control by the programming controller PLC control system of each workshop section, after certain conveyor was carried that the work of one group of charcoal piece is finished and be out of service, corresponding system promptly sent sound and light signal notice stacking overhead travelling crane and comes to take, put the charcoal piece.Stacking overhead travelling crane is come this conveyor top and is stretched out anchor clamps and takes, puts in the charcoal piece operation process, and floor conveyor is answered the No starting operation, otherwise conveyor will cause device damage with stacking overhead travelling crane anchor clamps generation hook.Therefore, when stacking overhead travelling crane on certain conveyor during idle job, stacking overhead travelling crane should send " locking " signal to the PLC system of this conveyor of control, this conveyor No starting of interlocking, after stacking overhead travelling crane was finished this subjob and left, interlocking signal was removed, and this conveyor could start operation.
At present, stacking overhead travelling crane in the prior art generally adopts " the signal trolley transmits locking signal ", " overhead traveling crane and ground control system install wireless remote controller additional and transmit locking signal " and " utilizing higher-order of oscillation switch to send and the reception locking signal " three kinds of modes to the interlocking of floor conveyor, and the shortcoming of the principle of work of these three kinds of modes and existence is as described below in the prior art:
The signal trolley transmits " locking " signal:
Set up the special signal trolley along stacking overhead travelling crane walking track, when needs locking floor conveyor, on the stacking overhead travelling crane control stand, press " locking floor conveyor " button or switch by the stacking overhead travelling crane driver, electric signal is sent to the PLC system of corresponding workshop section through the signal trolley.There is following shortcoming and defect in this mode:
In same charcoal piece transfer station, the many treads conveyor that connects each workshop section is often arranged, stacking overhead travelling crane locking is wherein during a conveyor, can not influence other conveyor work, therefore every conveyor all must be equipped with the signal trolley separately, add the power trolley of stacking overhead travelling crane, then the One's name is legion of trolley causes construction investment increase, maintenance workload to strengthen.With one 100 meters long charcoal piece transfer stations (general charcoal piece transfer station length is all more than 100 meters) is example, signal trolley of every increase, and palpus increase equipment and erected cost are 40,000 yuan approximately, and " locking " signal of both every tread conveyor must spend 40,000 yuan.
When stacking overhead travelling crane fulfil assignment leave certain conveyor after, the stacking overhead travelling crane driver needs to remove " locking floor conveyor " button or switch, floor conveyor could startup work.When being busy with one's work, the stacking overhead travelling crane driver often forgets ring off signal, and floor conveyor always can not be started, and has a strong impact on production efficiency.
Must on the stacking overhead travelling crane control stand, install " locking floor conveyor " button or switch, make the stacking overhead travelling crane operation circuit complicated.
Overhead traveling crane and ground control system install wireless remote controller additional and transmit " locking " signal:
The wireless remote control emitter is installed on stacking overhead travelling crane, wireless remote control receiving device is installed on the ground.When needs locking floor conveyor, on the stacking overhead travelling crane control stand, press " locking floor conveyor " button or switch by the stacking overhead travelling crane driver, electric signal is passed through the receiving trap that the wireless remote control emitter is sent to ground, deliver to the PLC system of corresponding workshop section again by receiving trap.There is following shortcoming and defect in this mode:
Every stacking overhead travelling crane of wireless remote controller must be provided with a cover, and every cover expense 2～30,000 yuan causes construction investment increase, maintenance workload to strengthen.
When stacking overhead travelling crane fulfil assignment leave certain conveyor after, the stacking overhead travelling crane driver needs to remove " locking floor conveyor " button or switch, floor conveyor could startup work.When being busy with one's work, the stacking overhead travelling crane driver often forgets ring off signal, and floor conveyor always can not be started, and has a strong impact on production efficiency.
When wireless remote controller is installed, must on the stacking overhead travelling crane control stand, install " locking floor conveyor " button or switch, make the stacking overhead travelling crane operation circuit complicated.
In same charcoal piece transfer station, dispose many stacking overhead travelling cranes and floor conveyor, then many cover wireless remote controllers are worked simultaneously, easily produce mutually and disturb, and make " locking " signal malfunction or motionless, easily cause equipment and personal injury.
Utilize higher-order of oscillation switch to send and reception " locking " signal:
A higher-order of oscillation emission switch is installed on stacking overhead travelling crane, is connected " locking floor conveyor " button or switch on the control stand.By every tread conveyor, higher-order of oscillation receiving key is installed in the position of the higher-order of oscillation emission switch on the corresponding overhead traveling crane, is connected to the PLC system of corresponding workshop section.When needs locking floor conveyor, also contraposition is accurate by the stacking overhead travelling crane driver overhead traveling crane to be parked in this conveyor top, press " locking floor conveyor " button or switch on the control stand then, " locking " signal is sent to the PLC system of the corresponding workshop section in ground through higher-order of oscillation switch.There is following shortcoming and defect in this mode:
When stacking overhead travelling crane fulfil assignment leave certain conveyor after, the emitting head of higher-order of oscillation switch and receive no longer alignment of head, the disconnection of " locking " signal.But if the stacking overhead travelling crane driver forgets releasing " locking floor conveyor " button or switch, then stacking overhead travelling crane is every all can make it be " locked " through a tread conveyor to stop once.Gently then have a strong impact on production efficiency, heavy then equipment and personal injury easily take place.
This mode requires the stacking overhead travelling crane contraposition very accurate, and the head that transmits and receives of higher-order of oscillation switch is alignd.If contraposition has deviation slightly, gently then " locking " signal can't transmit, and will be heavy then slightly go here and there and cause signal interruption owing to the stacking overhead travelling crane position in the stacking overhead travelling crane operation process, and equipment and personal injury very easily take place.
Higher-order of oscillation switch emitting head is installed on the overhead traveling crane, is given a shock with the overhead traveling crane walking, and failure rate is very high.
Must on the stacking overhead travelling crane control stand, install " locking floor conveyor " button or switch, make the stacking overhead travelling crane operation circuit complicated.
