Description
Technical field
The utility model relates to metallurgical steel rolling equipment field, particularly a kind of cooling bed steel-feeding roller-way drive unit.
Background technology
In metallurgy bar, section bar continuous production line, walking beam cooler equipment is absolutely necessary visual plant.In cooling bed device, the parts of most critical are cooling bed steel-feeding elevating apron plate and upper steel rider road.The effect of cooling bed steel-feeding roller-way is by the rolled piece of finisher rolling after Double Dimension Flying Shears segmentation, at high speeds two, front and back rolled piece is realized high-speed separation, avoids rolled piece to knock into the back.This roller-way length is generally at 60 meters about-120 meters, and roll spacing is 1.2 meters, and roller quantity is generally at 50-100 root, and each roller adopts separate electrical motor transmission.Rolling mill practice requires the accurate transmission between 12m/s-22m/s of this section of roller line speed.
At present, for realizing the precision of roller-way transmission, have employed motor output shaft and the direct coupled mode of roller-way, as shown in Figure 1, defect below existing cooling bed steel-feeding roller-way drive unit exists in production real process in 2: what 1) carry due to this roller-way is high temperature rolled piece, and rolled piece temperature reaches 800 DEG C about-1000 DEG C, motor and rolled piece distance very near, motor is in hyperthermia radiation environment, causes machine operation bad environments; Roller-way both directly contacted with rolled piece simultaneously, directly connected again with motor, and the heat of high temperature of rolled piece is directly transmitted to motor position by roller-way (roller-way is that metal makes), causes motor burning serious, both affects production, and turn increased equipment operating cost.2) upper steel rider road very easily weares and teares in process of production, changes very frequent; Steel rolling operation is a kind of consecutive production operation, and for ensureing rhythm of production, the time changing roller is very short, and for ensureing fast roll changing, new roller spare part must be deposited with motor integral is standby, causes spare parts consumption to be worth too high, adds production cost significantly.
Summary of the invention
The purpose of this utility model will overcome the above problems exactly, there is provided one can meet the accurate transmission requirement of cooling bed steel-feeding roller-way, the drive unit in roller-way driving motor service life can be improved again, significantly reduce the cooling bed steel-feeding roller-way drive unit of production cost simultaneously.
The technical solution of the utility model is achieved in that a kind of cooling bed steel-feeding roller-way drive unit, and it comprises roller, roller bed frame, bracing or strutting arrangement, driving motor; Roller and bracing or strutting arrangement are assembled into one, and by two bearings, roller is fixed in roller bed frame by flange by bracing or strutting arrangement; Be characterized in: bracing or strutting arrangement output sleeve is equipped with synchronous pulley, driving motor is arranged on the pivoting support that is positioned at below synchronous pulley; Lower synchronous pulley is sleeved on the output shaft of motor, and synchronous belt is tightly placed on synchronous pulley and lower synchronous pulley.
The utility model changes motor position, makes motor away from the working environment of hyperthermia radiation, conduction, improves electrical machinery life; Select toothed belt transmission mode, ensured that transmission accuracy meets technological requirement; Change current spare part confined state, reduce the cost producing spare part.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of existing cooling bed steel-feeding roller-way drive unit.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is that the A of Fig. 2 is to schematic diagram.
In figure: 1---high temperature rolled piece; 2----roller; 3---roller bed frame; 4---bracing or strutting arrangement; 5---upper synchronous pulley; 6---synchronous belt; 7---lower synchronous pulley; 8---motor; 9---pivoting support.
Specific embodiments
Upper steel rider road altogether 50-100 root roller, this programme illustrates for wherein 1 roller.
From Fig. 2 and Fig. 3, columniform high temperature rolled piece 1 is by the rotation conveying (linear velocity is 12m/s-22m/s) at a high speed of roller 2, and roller 2 and bracing or strutting arrangement 4 are assembled into one, by two bearings, rotation.Roller 2 is fixed in roller bed frame 3 by flange by bracing or strutting arrangement 4.Bracing or strutting arrangement output sleeve is equipped with synchronous pulley 5.
Driving motor 8 is arranged on pivoting support 9, and motor 8 center of gravity is deflected downwardly pivoting support 9 pin joint, can realize utilizing gravity tensioning synchronous belt 6 by which.
Lower synchronous pulley 7 is sleeved on the output shaft of motor 8, and synchronous belt 6 is tightly placed on synchronous pulley 5 and lower synchronous pulley 7, and motor 8 passes through synchronous belt 6 by power transmission to roller 2, driven roller 2 High Rotation Speed conveying high temperature rolled piece 1.
Motor position is arranged in the below away from rolled piece by this device, and motor does not directly connect with roller simultaneously, and the temperature radiation of high temperature rolled piece significantly reduces motor impact, and the heat of rolled piece can not be directly transferred on motor.For realizing the precision of roller line speed transmission, adopting toothed belt transmission mode, ensure that motor is delivered to the speed of roller-way error free.Timing Belt is a kind of engaged transmission, although Timing Belt is elastomer, but because the carrying rope wherein bearing load has the characteristic of not extending under a stretching force, therefore energy retainer belt pitch is constant, make band and wheel teeth groove energy correct engagement, realize the Synchronous Transmission without slippage, obtain accurate gearratio, ensure that the high controllability of roller-way transmission speed precision.In addition, because Timing Belt makes nonslipping Synchronous Transmission, therefore there is higher transmission efficiency, generally can reach 0.98, have obvious energy-saving effect.If adopt other modes, such as Chain conveyer, V-belt transmission etc., can not reach above effect simultaneously.
This device adopts motor+synchronous belt type of drive, eliminates motor and roller associated mode, changes the harsh environments of motor, in turn ensure that the exact controllability of roller-way transmission speed simultaneously.This device changes the position of motor, makes motor away from the harsh environments of hyperthermia radiation, high temperature conduction, drastically increases the service life of motor.
