Description
Technical field
The utility model relates to cold rolling mill equipment, relates in particular to a kind of milling train broken belt draw-gear, is used for quick traction milling train fracture belt steel.
Background technology
In the cold continuous rolling production accident, the milling train broken belt is a Common Accidents, occurs directly to cause milling train to be shut down after the broken belt accident, and operating rate descends, and therefore the processing requirements for the broken belt accident is rapid, efficient.At present, when milling train generation broken belt, common processing method is: 1) operating personnel enters frame, and two people cooperate, and are pulled out from roll gap by the band steel that will rupture in both sides; 2) will be with steel to pull out a segment distance after, cut open with electrical shear, the band steel that will downcut is again hauled out from frame; 3) repeat above-mentioned steps, until remove the band steel of breaking portion clean.
In above-mentioned operation process, because the position between frame is narrower, and there are the equipment such as guide board platform, calibrator, working space is narrow and small, tape steel effect of weight again, the rice number of once resecting is very limited, generally only has about 0.8 meter.Take common 3-4 frame broken belt as example, the band steel of fracture part generally can reach 12 meters to 15 meters, needs to use the driven shearing cutting broken belt partly could be removed for more than 10 times, and processing speed is slow, and labour intensity is larger.In addition, it also is typical man-machine in conjunction with operation that broken belt is processed, and the belt steel thickness of cold rolling unit is generally less than 1mm, some thin gauge strip thickness even below 0.3mm, limit section is very sharp, adopts the method for manually cutting, carrying very easily to cause incised wound, has higher potential safety hazard.
The prior art existing problems:
1, the use driven shearing will be lower with the method efficient of carrying after the steel segmentation cutting, process length consuming time, and labour intensity is large;
2, operation narrow space between frame, the steel edge portion cutting edge is sharp, very easily causes security incident during processing.
Summary of the invention
The purpose of this utility model is to provide a kind of milling train broken belt draw-gear, can behind broken belt, as early as possible the band steel that ruptures in the frame be cleaned out, and reduce operating personnel's input, the minimizing personnel with contact reduction potential safety hazard when improving processing speed with steel.
For achieving the above object, the technical solution of the utility model is:
A kind of milling train broken belt draw-gear, it comprises, and brace summer is installed in rolling-mill housing memorial archway top, and the brace summer lower surface is offered guide groove along its length; Telescopic arm is the Multi-section retractable structure, and its upper end is slidedly arranged in the guide groove of described brace summer lower surface, moves along guide groove; Batch arm, the one end pivoting is connected in described telescopic arm lower end minor details, comprises, the upper and lower bar that batches arranges up and down at interval, on to batch bar be hollow structure, and establish the oil gun interface, the lower surface is offered some through holes along its length, establishes some compact heaps in the through hole; Be used for driving the turning handle that batches that batches the arm rotation, be connected in and batch the outer end that arm is positioned at described telescopic arm lower end minor details.
Further, road wheel or slide block are established in described telescopic arm upper end, and are slidedly arranged in the guide groove of described brace summer lower surface with this.
Again, also comprise a rotating shaft, be arranged at described telescopic arm lower end minor details, the described upper and lower bar that batches of arm that batches is connected in rotating shaft one end, and the described turning handle that batches is connected in the rotating shaft other end.
In addition, the utility model also comprises securing rod, and its top rotatably is arranged on the brace summer, and the spacing stop pin of telescopic arms lower end minor details is established in the lower end.
During normal production, telescopic arm shrinks, and whole device is in the off-line position.When milling train generation broken belt, the rotation lock rationed marketing, put down telescopic arm, make device enter online position, oil gun pressure release, the oil gun interface oil gun of plugging into, injection liquid force feed in the cavity that batches arm, compact heap protrudes under the hydraulic oil effect and batches bar, under batch bar and the band steel compressed under cooperating, turning handle is batched in rotation, will be with steel to pull out and roll; After broken belt batches end, telescopic arm is followed away groove release frame, will be with the disposable removing of steel, return to normal production.
The beneficial effects of the utility model
The utility model utilization will be batched behind the broken belt band head clamping with the devices for taking-up of chute, can the disposable whole windings of band steel with all fractures in the frame gets up and cleans out.Compare with original broken belt processing method, save the repeatedly cutting steel plate operation that many people cooperate, avoided the people and contacted with the direct of steel, whole operation process only needs one, two people to finish basically, reduce labour intensity when improving operating efficiency, also significantly reduced the hazards of operation process.
