It releases or retracts, send offline roller-way 8 to transport rectangular casting blank 1 to cold to control hydraulic steel-drawing machine 7.
The course of work of the present invention:
After certain the one stream sending 1 arrival signal of rectangular casting blank of ejection roller way 2, hook steel machine 5 drives towards ejection roller way from standby position
2, suspension hook is in a high position at this time, is parked in by control system control hook steel machine 5 and takes base position, and hoist hook declines supreme hook position and takes base,
After taking base, hook bottom is promoted to higher than the base face position 100mm, lower one stream is driven towards and takes base position, hoist hook drops to low hook position
Base is taken, after taking base, is promoted to hook bottom higher than the base face position 100mm, there are slab, single in 5 height hook position of hook steel machine at this time
Base is taken to finish.
Instructed when control system issues, rectangular casting blank 1 need to carry out it is cold hook steel machine 5 is controlled by control system when sending offline,
Two pieces of rectangular casting blanks 1 are transported to above slab transfer 6 rack of cold bed.The first optoelectronic switch at slab transfer 6 rack of cold bed
When 24 signals are 0, indicate that at this moment 5 hoist hook of hook steel machine drops to low level, and two pieces of rectangular casting blanks 1 are placed on herein without slab 1
Slab is transferred on 6 rack of cold bed, and 5 hoist hook of hook steel machine exits, and rises to a high position, is driven towards and is taken base position next time, and waiting takes base;
Otherwise, hook steel machine 5 is in hook-shaped state under waiting.
When 24 signal of the first optoelectronic switch is 1 at slab transfer 6 rack of cold bed, expression has rectangular casting blank 1, slab herein
It transfers 6 lifting cylinder 17 of cold bed to stretch out, the rising of cold bed 6 is connected to slab 1, and then translation oil cylinder 20 stretches out.Lifting cylinder 17 retracts,
Cold bed 6 declines, and rectangular casting blank 1 is translate forward the long L1 of single step.Translation oil cylinder 20 retracts, and slab transfer cold bed 6 returns to original
A cycle is completed in position.Slab transfers 6 one circulation action order of cold bed: base-decline-return is transported in rising-translation.Consider
To the long L1 of single step less than two rectangular casting blanks 1 and column width W, it is therefore desirable to it is complete as one to translate two long L of single step
After translation motion, hook steel machine 5 carries out putting base again.
When needing that slab is cold to send offline, after hydraulic steel-drawing machine 7 receives the signal of the arrival of rectangular casting blank 1, oil cylinder 28 is released,
Rectangular casting blank 1 is pushed into a step-length L2 backward.There are three pusher dogs for setting on hydraulic steel-drawing machine 7, after pushing away steel three times, by square
Shaped cast base 1 is pushed to cold send on offline roller-way 8:
When it is cold send on offline roller-way detection device to detect that rectangular casting blank arrives when, it is cold that offline roller-way is sent to open, prepare defeated
Rectangular casting blank is sent, it is cold that offline second group of roller-way is sent to open for 6~7.6m scale base, it is conveyed with the speed of 60m/min to steel rolling
Rectangular casting blank, to it is cold send offline second group of roller-way rectangular casting blank to convey after, it is cold to send offline first group of roller-way and second group of roller
Road is synchronous to be opened, and equally conveys rectangular casting blank to steel rolling with the speed of 60m/min, and device detection rectangular casting blank to be detected is all defeated
Cold that offline roller-way is sent to stop after sending, hydraulic steel-drawing machine continues to push away base, cold to send offline roller-way for being greater than 7.6m scale base
It is all turned on, rectangular casting blank 1 is conveyed to steel rolling with the speed of 60m/min, send offline roller-way rectangular casting blank all to convey to cold
Bi Hou, cold that offline roller-way is sent to stop, hydraulic steel-drawing machine continues to push away base.
It is offline if necessary to the interim clamp of slab, send third optoelectronic switch 32 on offline roller-way 8 to detect that rectangle is cast when cold
When base 1 arrives, needs artificial judgment whether to integrate 4 rectangular casting blanks 1 offline, be packed together on hydraulic steel-drawing machine 7 at this time
4 rectangular casting blanks 1 hung by clamp and once hang away.It is more to need manually to be done when rectangular casting blank 1 needs interim offline
In advance, signal otherwise is transmitted without normal direction crane.
