Abstract
The utility model discloses a crystallizer width adjustment device, which comprises a guide rod (1), wherein one end of the guide rod (1) is connected with a narrow crystallizer back plate (2) which is fixed with a narrow crystallizer copper plate (9), and the other end thereof penetrates into a sleeve pipe (4) fixed on a narrow water tank (3); the sleeve pipe (4) is internally provided with a screw rod (5), one end of the screw rod (5) is provided with a double-nut pretension planet roller nut (6), the double-nut pretension planet roller nut (6) is connected with the end surface of the guide rod (1) by a lock bolt (7), and the other end of the screw rod (5) is connected with a screwed transmission device (8) arranged on the narrow water tank (3). The utility model has the advantages of simple structure, short transmission chain, high transmission and position precision and precise self-locking.
Description
Technical field
The utility model relates to the Width adjusting device of a kind of conticaster crystallizer, particularly a kind of conticaster crystallizer.
Background technology
Crystallizer is a kind of visual plant in the conticaster, and after molten steel entered crystallizer, cooling formed the base shell, adjusts the width of crystallizer simultaneously by Width adjusting device, with the strand of cast different in width.
At present, in steel production in China enterprise, the mechanical Width adjusting device of the many employings of the crystallizer Width adjusting device of conticaster, though this Width adjusting device is feasible, but because the driving-chain of this class Width adjusting device is long, make that the precision of each transmission mechanism is low, self-locking and braking power deficiency makes that the on-line width adjustment positioning accuracy is low and the phenomenon that width drifts about occurs in casting cycle.
The utility model content
The purpose of this utility model just provides a kind of transmission and the high crystallizer Width adjusting device of positioning accuracy.
The purpose of this utility model is to realize by such technical scheme: a kind of crystallizer Width adjusting device, comprise guide post, one end of guide post is connected with the narrow limit crystallizer backboard that narrow limit copper plate of crystallizer is fixed, the other end penetrates in the sleeve pipe that is fixed on the water tank of narrow limit, in sleeve pipe, be provided with leading screw, an end that it is characterized in that described leading screw is provided with double nut pretension planetary roller nut, double nut pretension planetary roller nut is connected with the end face of guide post by check bolt, and the other end of described leading screw is connected with helicoidal gear on being arranged on narrow limit water tank.
In order to make helicoidal gear possess auto-lock function, helicoidal gear is provided with brake, and described brake is a disk brake.
When assembling, apply a pretightning force for earlier double nut pretension planetary roller nut, eliminate the gap between this nut and the leading screw, do transmission of no gap and the location that just can realize between leading screw and the double nut pretension planetary roller nut like this.
The utility model is work like this: the helicoidal gear that drives by motor reducer drives the leading screw rotation, the leading screw that rotates promotes double nut pretension planetary roller nut and moves on leading screw, the double nut pretension planetary roller nut that moves promotes guide post and moves forward or backward with the narrow limit crystallizer backboard that guide post connects, and has realized the online accurate adjusting of crystallizer width.After adjustment was finished, disk brake on the helicoidal gear and the brake on the motor reducer were braked simultaneously, had produced a braking moment, made the accurate self-locking of Width adjusting device.
The utlity model has compact conformation, the short advantage of driving-chain, simultaneously, it also has following advantage:
1. gapless transmission has improved transmission accuracy, also makes the precision of Width adjusting device when the location be improved simultaneously, has realized the accurate transmission and the location of crystallizer width;
2. the generation of brake force makes the accurate self-locking of Width adjusting device, the drift that has occurred when having prevented casting.
In a word, the utility model can be implemented in line and transfers wide accurate transmission and location, and the accurate self-locking of Width adjusting mechanism prevents that Width adjusting mechanism from drift occurring when casting, can be widely used on the crystallizer with mechanical Width adjusting device.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Embodiment 1: as shown in Figure 1, a kind of crystallizer Width adjusting device, comprise guide post 1, one end of guide post 1 is connected with the narrow limit crystallizer backboard 2 that narrow limit copper plate of crystallizer 9 is fixed, the other end penetrates in the sleeve pipe 4 that is fixed on the narrow limit water tank 3, in sleeve pipe 4, be provided with leading screw 5, one end of described leading screw 5 is provided with double nut pretension planetary roller nut 6, double nut pretension planetary roller nut 6 is connected with the end face of guide post 1 by check bolt 7, and the other end of described leading screw 5 is connected with helicoidal gear 8 on being arranged on narrow limit water tank 3.Leading screw 5 in this example and helicoidal gear 8 are for being wholely set, and wherein, helicoidal gear 8 is provided with brake.Brake in this example adopts disk brake.
Described helicoidal gear, disk brake and double nut pretension planetary roller nut are now to sell product on the market.
Claims (2)
1. crystallizer Width adjusting device, comprise guide post (1), one end of guide post (1) is connected with the narrow limit crystallizer backboard (2) that narrow limit copper plate of crystallizer (9) is fixed, the other end penetrates in the sleeve pipe (4) that is fixed on the narrow limit water tank (3), in sleeve pipe (4), be provided with leading screw (5), it is characterized in that: an end of described leading screw (5) is provided with double nut pretension planetary roller nut (6), double nut pretension planetary roller nut (6) is connected with the end face of guide post (1) by check bolt (7), and the other end of described leading screw (5) is connected with helicoidal gear (8) on being arranged on narrow limit water tank (3).
