Limit downslide amount Δ sj equals the distance between induced signal switch 4 and the following induced signal switch 5.The length of described inductor 2 should be able to be sensed the signal of induced signal switch 4 and following induced signal switch 5 at least simultaneously.Described upward induced signal switch 4, the position inductive switch 8 that allows to glide are connected with instrument joystick 7 with operation switch 6 with following induced signal switch 5 and interlock; Operation switch 6 is provided with change poles, crust breaking, mulch, drags for slag instrument shelves and zero-bit shelves; When operation switch 6 was positioned at the instrument gear of working, last induced signal switch 4 was as upper limit control, and following induced signal switch 5 is as up deceleration control, and the position inductive switch 8 that allows to glide lost efficacy; When operation switch 6 was positioned at the instrument shelves of not working, last induced signal switch 4 detected control as gliding, and following induced signal switch 5 is as end position control, and the position inductive switch 8 that allows to glide is effective; The zero-bit shelves are lock catch.
Principle of work of the present invention and working process
Its principle as shown in Figures 2 and 3, Fig. 2 is that inductor is positioned at the scheme drawing that allows the downslide scope; Fig. 3 is the scheme drawing that inductor is lower than end position.This device can allow the permission downslide amount Δ sy that slides into setting under the instrument, when the position inductive switch 8 that promptly allows to glide sends signal, or (Δ t=Δ ss ÷ v during the downslide time Δ t that sets, Δ ss is actual downslide amount, v is a slip velocity), send signal and (the downslide amount Δ s time corresponding that promptly the slides into setting down) back of delaying time the Δ t time automatic and instrument lifting drive give a signal and warning by the last induced signal switch 4 that is arranged on the instrument, make actuating device obtain behind the signal automatic lift instrument is resetted (promptly go up induced signal switch 4 signal is arranged), if the limit downslide position (as shown in Figure 3) that instrument continues to slide into down setting occurs, then descend induced signal switch 5 to send signal and report to the police and make actuating device obtain behind the signal automatic lift instrument is resetted (promptly go up induced signal switch 4 signal is arranged), and stop the big of overhead traveling crane automatically, carriage walking.The auto alarm purpose is that overhaul as early as possible in the prompting workshop.The present invention overcomes instrument that prior art exists and glides and overhead traveling crane will take place and mechanical collision case danger takes place in upper part of the electrolytic cell mechanism.
During concrete enforcement, inductor 2 is set on instrument movable part 1; Induced signal switch 4 and following induced signal switch 5 are set on instrument fixed guide part 3, allow an inductive switch 8 that glides, operation switch 6 (power tool change-over swith) and instrument joystick 7 are set on overhead traveling crane control wheel (or remote controller), and the length of inductor 1 should be able to be sensed two signals of induced signal switch 4 and following induced signal switch 5 at least simultaneously.The residing mode of operation of instrument at last induced signal switch 4 and following induced signal switch 5 corresponding places different and play the part of different roles: when operation switch 6 is transformed into the instrument of work at present, last induced signal switch 4 is the up slow down switch of inductor 2 as induced signal switch under the upper limit position switch of inductor 25, and the position inductive switch that allows to glide lost efficacy; When operation switch 6 was transformed into the instrument of non-work at present, last induced signal switch 4 became the downslide detector switch of inductor 2, induced signal switch 5 becomes the limit downslide detector switch of inductor 2 down, and the position inductive switch that allows to glide is effective; Promptly go up induced signal switch 4 and following induced signal switch 5 and allow to glide the signal of position inductive switch and the tool operation interlocking of signals of operation switch 6.Its course of action is as follows:
When operation switch 6 does not switch to the tool operation at induced signal switch 4 and following induced signal switch 5 places (being transformed into other arbitrary power tool), the then last induced signal switch 4 on the instrument, following induced signal switch 5 and allowing this tool operation interlocking of signals of position inductive switch 8 and operation switch 6 that glides, this at present induced signal switch 5 as the limit downslide detector switch of inductor 2, go up the downslide detector switch of induced signal switch 4 as inductor 2, the position inductive switch 8 that allows to glide is effective.When not having induced signal between last induced signal switch 4 and the inductor 2, specification tool begins to glide, pick up counting this moment, delay time to behind the time Δ t (i.e. correspondence setting automatic lift downslide amount required time of Δ s shown in Figure 2) that sets, time delayed signal and 7 pairs on tool operation bar by last induced signal switch 4 should be interlocked by instrument rising operation signal, send this instrument automatic lift reset signal and report to the police, make actuating device obtain behind the signal automatic lift instrument reset (promptly go up induced signal switch 4 signal is arranged).The method of Δ t if need not delay time and use allow the to glide method of position inductive switch 8 of fixed installation instead, then when not having induced signal between last induced signal switch 4 and the inductor 2, specification tool begins to glide, when allowing a downslide position inductive switch 8 to send signal, signal and 7 pairs on tool operation bar by signal switch 8 should be interlocked by instrument rising operation signal, send this instrument automatic lift reset signal and report to the police, make actuating device obtain behind the signal automatic lift instrument reset (promptly go up induced signal switch 4 signal is arranged).
Allow to illustrate that reset attachment breaks down below the downslide amount Δ sy if occur sliding under the instrument continuation setting, need overhaul (as shown in Figure 3) device.When under inductor 2 continues, sliding to down induced signal switch 5 positions (limit downslide position), following induced signal switch 5 sends signal alarm, the automatic lift instrument resetted (promptly go up induced signal switch 4 signal is arranged) after simultaneously actuating device obtained signal, and the large and small garage that stops overhead traveling crane is automatically walked.The auto alarm purpose is that overhaul as early as possible in the prompting workshop.
