The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but never in any form the utility model is limited, and any conversion of doing based on the utility model, all falls into the utility model protection domain.
As shown in Fig. 1 ~ 5, the utility model comprises PLC system 9, mechanism's upper limit sensor, HBC remote controller 3 and electric whistle 4, the load module of described PLC system 9 is connected with mechanism upper limit sensor, and output module is connected with electric whistle 4, and DNB module is connected with HBC remote controller 3.
Described mechanism's upper limit sensor comprises crust breaking sensor 5,1# anode sensor 6,2# anode sensor 7 and drags for slag sensor 8.
Described mechanism's upper limit sensor is inductive pickoff, is arranged at the upper limit position of crust breaking, anode and dragveyer structure.
The DNB module of described PLC system 9 is connected with cart frequency converter 1.
The DNB module of described PLC system 9 is connected with rolling cart frequency converter 2.
Described HBC remote controller 3 is parallel with one another with cart frequency converter 1 and rolling cart frequency converter 2.
Described PLC system 9 is connected with Hydraulic Station actuation signal.
Described electric whistle 4 is arranged in overhead traveling crane OPS.
principle of work of the present utility model and working process:
Principle of work of the present utility model: utilize PLC system, whether at upper limit position, sensor feedback signal imports PLC load module into by the each instrument of Sensor monitoring in crust breaking, anode and the installation of dragveyer structure upper limit position; Detect remote controller signal simultaneously; the receptor of HBC Digiplex is by D net and plc communication; judge whether certain instrument is not or not people is normal running in the time of upper limit position; distinguish and make command adapted thereto through PLC; finally by PLC output module, instruction is communicated on each actuating unit to detection alarm and operation protection that implementation tool glides.
Working process of the present utility model:
One, when starting overhead traveling crane, moves HBC Digiplex while controlling operation, the load module of PLC sends and detects the upper limit sensor of instruction to crust breaking, anode, dragveyer structure, position signal is fed back to load module by sensor, if crust breaking, anode, dragveyer structure are all at upper limit position, PLC sends move to the large dolly frequency converter of overhead traveling crane, and overhead traveling crane moves; If a certain mechanism is not in the upper limit, PLC sends detection instruction to HBC Digiplex, whether distinguish the mechanism at the non-upper limit position of operation, if so, PLC sends move to the large dolly frequency converter of overhead traveling crane, and overhead traveling crane moves, if not, the output module of PLC sends the interval alarm command of a second to the electric whistle of overhead traveling crane, does not send overhead traveling crane move, and overhead traveling crane is static.
If two overhead traveling cranes are in the time using certain instrument, after stagnating in short-term, and now the instrument select switch of the projector of HBC Digiplex is beaten on the tool mechanism of non-upper limit, for reminding operative employee to have tool mechanism not at upper limit position, PLC control program will be after the upper limit sensor parallel connection of all mechanisms the startup of the upper Hydraulic Station of series connection again, and stop add the time delay of 3min on Hydraulic Station starts after.Be tool mechanism attonity in 3min, just the Hydraulic Station of startup stops automatically, as long as now have any instrument not at upper limit, the output module of PLC sends the interval alarm command of a second to the electric whistle of overhead traveling crane, limits the movement of overhead traveling crane simultaneously.
Three, consider that overhead traveling crane stops the not used time, the projector of HBC Digiplex cuts out, with the PLC of overhead traveling crane without communication, main startup is closed, overhead traveling crane is irremovable, can not bump, and does not now need to report to the police, so the open contact of main startup in the series connection below of PLC control program, the used time does not report to the police so just to have realized overhead traveling crane.When the projector of HBC Digiplex starts, set up after communication with PLC, while starting main startup preparation mobile overhead crane operation, PLC load module detects that arbitrary mechanism is not or not the time of upper limit position, output module just sends the interval alarm command of a second to the electric whistle of overhead traveling crane, limits the movement of overhead traveling crane simultaneously.
The beneficial effects of the utility model:
One, in the time that downslide in various degree appears in the part instrument of overhead traveling crane, can remind overhead traveling crane operative employee in the very first time, avoid the generation of accident.
Two, avoid overhead traveling crane operative employee in the time instrument not being risen to upper limit, just to intend moving other mechanisms or start overhead traveling crane and the human accident that causes.
Three,, in the time that instrument glides, overhead traveling crane operative employee can judge that certain mechanism glides accurately, has improved the accuracy that operative employee reports for repairment.
