Description

A kind of anti-run-off device of horizontal loop
Technical field
The utility model is related to a kind of anti-run-off device of horizontal loop, belongs to mechanical field.
Background technology
The stainless cold rolling mill 4# cold lines unit of Taiyuan Iron and Steel Co. is designed by German Sundwig over contracts, is configured with entry loop 2, is gone out Mouth kink 2, smooth small kink 1.Due to design problem, since operation of going into operation, unit had occurred up to a hundred kinks and taken off Hook phenomenon, especially entry loop unhook phenomenon are frequent.Run-off is caused to cause steel belt deviation because kink breaks off relations, the quality volume caused Million are crossed with equipment fault maintenance cost.Under the tissue of an inspection person, ten remainders are improved for the set hooking systems, but From the point of view of later stage service condition, effect is not it is obvious that unhook run-off phenomenon or the irregular outburst of meeting.By analysis for many years Come dolly unhook phenomenon and the at that time data such as corresponding set amount curve, speed of travel, it has been found that when each dolly breaks off relations, kink set Amount is in dolly easily unhook hidden danger region(When dolly upper arm is in the hook band of position by machine, kink holds toward complex transformation set amount Easily cause dolly unhook), the state, which is in, hooks critical condition, in the case where dolly is not tangled completely, suddenly change row Walk direction and cause unhook.
Dolly upper arm is in hook evolution set amount by machine, belongs to critical point problem, the unhook phenomenon can not pass through machine The complete radical cure of tool transformation.So we change a kind of angle, it is considered to cause dolly not occur after breaking off relations using a kind of band brake apparatus Run-off, a series of problems, such as also would not producing failure, quality.
The content of the invention
The utility model provides a kind of anti-run-off device of horizontal loop, is caused using a kind of band brake apparatus after dolly unhook not Can occur run-off, fundamentally solve the steel belt deviation run-off phenomenon occurred after loop trolley breaks off relations, and current dolly can be reduced Hazards during being rushed to repair after unhook;On the other hand dolly unhook phenomenon can be found in time using recoil simulator, it is to avoid mistake Go to find the serious consequence caused by evening.
The technical solution adopted in the utility model is:
A kind of anti-run-off device of horizontal loop, band brake apparatus, the band-type brake are provided between kink wheel and positioning upper arm Device includes linking arm, arc band-type brake piece, and linking arm fixing end is connected with trolley body, and fixing end is carried and shipped and resell on another market, linking arm Movable end is connected with dolly positioning upper arm by spring, and band-type brake piece is located at below linking arm, and radian and the work of arc band-type brake piece Cover wheel laminating.
In said apparatus, it is bolted between the band brake apparatus and loop trolley.
In said apparatus, the gap of the band-type brake piece and kink wheel is 0 ~ 3mm, and linking arm end is provided with regulating bolt, By the gap for the connection adjustment band brake apparatus for positioning wall built-up and regulating bolt.
In said apparatus, position is linked up with by machine proximity switch is installed, proximity switch is the auxiliary inspection of the anti-run-off device Device is surveyed, after dolly breaks off relations, can be detected in time.
Principle of the present utility model:1. install mechanical band brake apparatus additional on each recursion car wheel, broken off relations using dolly The difference in height of front and rear upper arm, makes unhook car wheel be in locking state, it is impossible to freely to walk;2. position and extension are linked up with by machine Proximity switch is installed in the preceding appropriate location of hook, and this group of proximity switch is only corresponding with the recursion dolly matched, when loop length is big Whether when a certain value, certain dolly should be in hook status, using proximity switch signal the dolly can be detected in extension Hook-shaped state, if unhook phenomenon occurs for dolly, can feed back to process(ing) cell by the signal very first time;3. it is in locking state The recursion dolly of unhook, because positioning upper arm is in appropriate height, when above dolly reversion, two dollies can be made voluntarily extensive State is hooked again.
The beneficial effect that the utility model is brought:The apparatus main body is that dolly adds a sleeve locking apparatus, is fundamentally solved The steel belt deviation run-off phenomenon that certainly loop trolley occurs after breaking off relations, and the danger during being rushed to repair after current dolly breaks off relations can be reduced Factor;The program is respectively provided with versatility for all similar kinks.
The utility model is described further with reference to the accompanying drawings and examples.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model use state schematic diagram.
1 is trolley body in figure, and 2 be that dolly positions upper arm, and 3 be to be linked up with by machine, and 4 be band brake apparatus, and 5 be linking arm, and 6 are Band-type brake piece.
Embodiment
Embodiment:
As illustrated in fig. 1 and 2, the anti-run-off device of a kind of horizontal loop, is provided between kink wheel and dolly positioning upper arm 2 Band brake apparatus 4, the band brake apparatus 4 includes linking arm 5, arc band-type brake piece 6, and the fixing end of linking arm 5 is connected with trolley body 1, And fixing end, with shipping and reselling on another market, the movable end of linking arm 5 is connected with dolly positioning upper arm 2 by spring, and band-type brake piece 6 is located at linking arm 5 Lower section, and the radian of arc band-type brake piece 6 fits with kink wheel.
In said apparatus, it is bolted between the band brake apparatus and loop trolley.
In said apparatus, the gap of the band-type brake piece and kink wheel is 0 ~ 3mm, and linking arm end is provided with regulating bolt, By the gap for the connection adjustment band brake apparatus for positioning wall built-up and regulating bolt.
In said apparatus, position is linked up with by machine proximity switch is installed, proximity switch is the auxiliary inspection of the anti-run-off device Device is surveyed, after dolly breaks off relations, can be detected in time.
Specifically preparation method is:Band brake apparatus is installed on each dolly of kink, before and after being hooked with above dolly The difference in height of upper arm is positioned, the opening and closing of band-type brake are realized.It is between dolly under normal hook state, band-type brake is opened;It is small State after unexpected break off relations, band-type brake closure occur for car.Special instruction:Under band-type brake closure state, dolly can not walk, treat the dolly with Above dolly recovers after hook state, and band-type brake is opened, so using this structure it is possible to prevente effectively from run-off phenomenon occurs in dolly.
The clearance adjustment method of band brake apparatus:According to kink wheel itself and positioning upper arm relative distance band-type brake customized, So that when positioning upper arm is fallen, band-type brake piece is fitted with wheel excircle;When positioning upper arm is lifted(The dolly and above dolly are extensive State is hooked again), band-type brake piece has about 3mm gaps with wheel excircle, and the gap can suitably be adjusted by regulating bolt at upper arm.
It is expected that economic benefit explanation:
1. it is annual to save because the quality volume loss that kink run-off is caused converts into about 100,000 yuan or so;
2. the annual dolly spare part loss saved because kink run-off is caused, steel wire rope lose about 150,000 yuan or so;
3. annual about 20 hours fault times of reduction, about 1500 tons of yield is increased, for 200 yuan of benefits per ton, often Year can increase by 200 yuan × 1500 tons=300,000 yuan of benefit;
4. the repairing of attendant, maintenance cost after kink breaks off relations are reduced.
About 600,000 yuan of total cost.
