Description
Technical field
The utility model relates to field of metallurgical equipment, particularly a kind of driving-chain rupture protection system that is applicable to the tower kink of driving upper set of the continuous process for producing line of tower kink band steel.
Background technology
The band continuous process for producing line of steel (galvanized wire, annealed wire etc.) is not only wanted to satisfy production technology and is handled the requirement that must not be interrupted continuously; Simultaneously, also want to satisfy the requirement that the user improves output and quality day by day.As unloading when operation volume carrying out coiling machine, can not shut down because of process section, equipment---the kink of storage band need be arranged, thereby kink is one of essential equipment of the band continuous process for producing line of steel.
Kink has tower (vertical) and horizontal two kinds of arrangement forms, and tower kink is big because of vertical layout, cover amount, take up an area of advantage such as little is widely used in being with the continuous process for producing line of steel.According to the diverse location of transmission system, transmission system is positioned at the driving upper set that is called of its upper side, and what transmission system was positioned at device bottom is called the tower kink of transmission underneath type.Mostly the tower kink of driving upper set is pure chain drive, and control accuracy does not receive the influence of steel wire rope distortion, and is because of more stable control performance, more in practical applications.
At present, the driving chain arrangement form of the tower kink of driving upper set: mostly driving chain is 4, and minority is 2, and a tip node of each chain is evenly arranged on the movable roll vehicle frame, walk around driven sprocket, drive sprocket after, the other end directly is connected on the balancing weight.
This transmission arrangement form has a serious defective: because 4 chains are difficult to adjust to equal in length, thereby unbalance stress is easy to make certain root chain stressed bigger.In case certain root chain ruptures; Movable roll car unbalance stress; Fracture, the movable roll car operation that can cause all the other chains de-orbit and gross distortion or balancing weight single-ended stressed moment accident such as fall take place; Cause kink to move, kink is directly scrapped under the serious situation, thereby causes the long-term stopping production of whole production line.
The utility model content
The purpose of the utility model is in order to overcome the deficiency on the driving-chain arrangement in the prior art, a kind of tower kink driving-chain fracture protective device to be provided, even the situation of certain bar driving-chain fracture takes place; Still can guarantee that the movable roll car can stable operation a period of time; Be unlikely to damage the kink main equipment, so that operator's on-call maintenance, behind the replacing chain; Can resume production, causality loss is reduced to minimum.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of tower kink driving-chain fracture protective device; Which comprises at least motor that is fixed on the frame and the reduction box that is connected with drive of motor through shaft coupling; It is characterized in that: the both sides output axle head of reduction box respectively is connected with a drive sprocket assembly pulley; Many chains all are that an end is connected with the movable roll car, and the other end is connected to counterweight through driven sprocket, drive sprocket assembly pulley after turning to; The center at movable roll car two ends respectively is connected with a protection rope simultaneously, and the other end of two protection ropes is connected to the center at counterweight two ends respectively after follow-up pulley, drive sprocket assembly pulley turn to; Between movable roll car and stationary roll device, store the band steel,, realize the change of looper cover amount along with the up-down of movable roll car.
Be connected through four chains between described movable roll car and the counterweight; The frame place is connected with four driven sprockets; Output axle head in reduction box both sides respectively is connected with a drive sprocket assembly pulley, an end of four chains be connected uniformly the movable roll car around, after the other end of four chains turns to through four driven sprockets earlier; Each two drive sprocket assembly pulley turns to through the reduction box both sides again, finally is connected to the two ends of counterweight.
Described from four movable sprockets be connected the movable roll car around directly over frame.
Each drive sprocket assembly pulley at described reduction box two ends be positioned at the counterweight two ends directly over, and be in same horizontal level with driven sprocket.
The frame place respectively is fixed with a follow-up pulley directly over the center, described movable roll car two ends.
In each drive sprocket assembly pulley that connects of described reduction box both sides output axle head, near the drive sprocket assembly pulley in the outside be positioned at center, counterweight two ends directly over, and be in same horizontal level with follow-up pulley
Described protection rope is steel wire rope.
The beneficial effect of the utility model is: chain no longer is the unique element that connects movable roll car and counterweight in this protective device; When motor when decelerator drives the drive sprocket assembly pulley; Along with the up-down of chain, the also oscilaltion of movable roll car, thus realize dashing cover, putting cover and move of kink; Simultaneously, because a protection rope has respectively been set up at two ends, steel wire rope is also along with chain is synchronized with the movement; But stressed minimum, just bear less pretightning force, in case certain root chain ruptures; The movable roll car can produce slight fluctuations, protects the load-bearing immediately of restricting, and makes movable roll car center stress balance; The movable roll car will even running, will avoid counterweight single-ended stressed moment accident such as fall to take place.
