Abstract
The invention relates to a locking system for a multi-functional crown block anode wrench for aluminium electrolysis. The locking system adopts the structure that a locking cylinder is arranged on the sliding rail of a wrench sliding plate of the multi-functional crown block anode wrench, and is controlled by a normally-closed type single electronic control pneumatic electromagnetic directional valve, wherein the electromagnetic directional valve is controlled by a PLC control system. In the case of disorderly shutdown and shutdown caused by human reasons or power off of an air compressor on the crown block, the locking system can lock the anode wrench, thereby preventing the anode wrench from falling off to smash the upper structure of an electrolyzer or other parts in an electrolytic plant, further improving the security of the crown block and ensuring safety electrolysis production.
Description
Technical field
The present invention relates to a kind of used for aluminium electrolysis multifunction crane anode spanner locking and fastening system.
Background technology
Safety is the prerequisite of producing, and also is the basis of all working.Equipment safety management work must be adhered to bringing in constant renewal in and transform, and improves the principle of safety method level, and the safety hazard in the abatement apparatus operational process is guaranteed company property and personal safety timely and effectively.Cloud aluminium company electrolysis one 186KA of factory manufacturing line ECL multifunction crane spanner mainly is fixed on upper limit to it by the high-pressure blast that Air compressor provides; In case Air compressor is in stopped status (disorderly closedown, artificially shutdown or car load power down shutdown), spanner will glide under the effect of its deadweight.The height of spanner lower end has been lower than the upper end of anode rod on pot superstructure upper end, the pallet at this moment.Therefore, the defective of this overhead traveling crane anode spanner existence in design is:
1. when using the partial function of overhead traveling crane, Air compressor need not be started and just work can be carried out; For the energy-conservation and artificial running that stops Air compressor; Spanner will be in low level because deadweight is glided so; The security risk that causes bumping against the anode on pot superstructure or the pallet in the overhead traveling crane operational process increases, and the operation easier of operating personal is increased.
2. Air compressor fault or car load power down in the overhead traveling crane use; The capital causes Air compressor out of service, if this moment rolling cart work on the electrolytic bath or anode tray above, spanner all can glide and bump against the anode on pot superstructure or the pallet; Exist very big potential safety hazard (spanner can take place bump against electrolytic bath; Cause the serious modification of spanner, the electrolytic bath airduct severs, and cylinder hits equipment breakdowns such as distortion).
Summary of the invention
When solving artificial shutdown, Air compressor fault or car load power down; No high-pressure blast is supplied with the spanner cylinder; Spanner can glide under the effect of its deadweight and the security hidden trouble that brings; The present invention provides a kind of multifunction crane anode spanner locking and fastening system, effectively avoids and overhead traveling crane collision accident, improves the safety that overhead traveling crane uses operation.
Technical scheme of the present invention is: multifunction crane anode spanner locking and fastening system is on the slide rail of the wrench sliding panel of multifunction crane anode spanner, the locking cylinder to be set; The locking cylinder is controlled by the single ecp solenoid directional control valve of a closed type, and this change-over valve is controlled with the PLC control system.
In case Air compressor is artificially shut down, when Air compressor disorderly closedown or car load power down are shut down, the PLC output module is a non-output signal, the electromagnetic valve dead electricity, and cylinder piston rod stretches out the locking spanner automatically under the spring force effect.
Use the safety control of the multifunction crane anode spanner that the present invention carried out transforming to reach good result, no matter be that Air compressor is artificially shut down, when Air compressor disorderly closedown or car load power down are shut down, spanner all can lock automatically, can not glide.The height of locking back spanner all is higher than the height of anode on pot superstructure and the pallet; Do not solved when overhead traveling crane anode spanner has locking and fastening system and shut down the potential safety hazard that anode bumps against on downslide and pot superstructure and the pallet, improved the safety that overhead traveling crane uses operation because of Air compressor.The transformation of the multifunction crane anode spanner during the present invention both can be used for having used at present also can be used for the new production multifunction crane the present invention is used for the anode spanner.

Among Fig. 4, X001-master starts input, the starting of X002-Air compressor, and the X003-spanner rises input; Input falls in the X004-spanner, and Y001-master starts output, Y002-electromagnetic switch valve coil; Y003-spanner output per litre, output falls in the Y004-spanner, B3-Air compressor starting relay.
The specific embodiment
Like Fig. 3, shown in 4; Multifunction crane anode spanner locking and fastening system of the present invention is that locking cylinder 7 is set on the slide rail 8 of the spanner sliding panel 6 of multifunction crane anode spanner; Locking cylinder 7 is controlled by the single ecp solenoid directional control valve 12 of a closed type; The single ecp solenoid directional control valve 12 of closed type is connected on the wind regime pipeline, and this change-over valve is controlled with the PLC control system.As shown in Figure 2; In case Air compressor is artificially shut down, when Air compressor disorderly closedown or car load power down are shut down; The PLC output module is a non-output signal, the switching-over of electromagnetic valve dead electricity, the quick air draft of cylinder vent window; Lean on cylinder rear end spring to promote in the locking hole of piston rod insertion spanner sliding panel 6 the locking spanner.
On the slide rail of the wrench sliding panel of multifunction crane anode spanner, the locking cylinder is set; With Air compressor open or the status signal that stops as the incoming signal of PLC, after treatment as output signal output, the single ecp solenoid directional control valve of a closed type is switched on or is cut off the power supply control; Thereby connect or stop to get into the wind regime of locking cylinder vent window; When realizing that Air compressor is in starting state, piston rod withdrawal locking cylinder, spanner can lift work; When Air compressor was in stopped status, piston rod stretched out the locking cylinder and inserts in the locking hole of spanner sliding panel 6, and the locking spanner does not glide it because of deadweight.
