Description
Technical Field
The utility model relates to a pinch roll complete device with a drive, and belongs to the technical field of steelmaking equipment.
Background
In the treatment process of the tail blank after continuous casting drawing and pouring, after the casting blank comes out of the last withdrawal and straightening machine, the roll table is affected by the on-site working condition, the driving rollers in the area from the roll table to the fire cutting machine are generally arranged less, a section of distance from the lower part of the fire cutting machine to the driving roller is longer, a small number of driving roller faults are encountered, the tail blank is difficult to be transported out of the area, only the crown block can be adopted to drag the casting blank out through a steel wire rope, and the like, so that the casting blank remained in the area is treated, the time and the labor are wasted, the temperature of the casting blank is higher, scalding risks exist for operators, the continuous casting downtime is longer in the treatment process, and the operation rate of continuous casting is seriously affected. In addition, if the situation that the installation precision of part of roller ways is not in place is caused, the head of the dummy ingot chain is required to be corrected by lifting the dummy ingot chain by a crown block, the dummy ingot feeding time is wasted, and if the dummy ingot chain is obviously deviated after continuous casting is started, the stream is required to be stopped and the production is interrupted; if the roller way conveying system is poor or the last withdrawal and straightening machine fails and cannot be driven under the condition of being capable of being pressed down, on one hand, the upward conveying of the dummy ingot chain is difficult, on the other hand, the dummy ingot chain after the dummy ingot is removed cannot be timely opened, and the continuous casting production is affected; if the phenomenon that the casting blank is immediately deviated due to the sudden damage of a bearing of an upper roller and a lower roller of an individual withdrawal and straightening machine occurs in the normal casting process of the casting blank, the emergency treatment is not timely, the top of the casting blank is dead, the flow is stopped, and the production is also interrupted immediately; if the withdrawal and straightening machine and the upward partial radian are not in place, the casting blank can deviate, and continuous production is affected seriously.
Disclosure of utility model
The utility model aims to solve the technical problem of providing the pinch roll complete device with the drive aiming at the prior art, which has the advantages of simple structure and convenient operation, so that a casting blank can be removed in time, time and labor are saved, and continuous production is ensured.
The utility model solves the problems by adopting the following technical scheme: a pinch roll complete device with drive comprises a rack, wherein pinch roll units are symmetrically arranged at an inlet of the rack, and can be relatively close to or relatively far away from each other so as to adjust the distance between the two pinch roll units; the two sides of the stand are symmetrically provided with water-cooling protection plates, and the water-cooling protection plates are arranged at the outlet of the pinch roll unit.
The pinch roll unit comprises pinch roll brackets, the pinch roll brackets are hinged to the frame, pinch rolls which are vertically arranged are arranged on the pinch roll brackets, two ends of each pinch roll are fixed on the pinch roll brackets through water-cooling bearing seats, a speed reducing motor which is vertically arranged is arranged below the pinch roll brackets, and the speed reducing motor is connected with a central shaft of each pinch roll through a disc spring group.
The two lateral surfaces of the stand are respectively provided with a horizontal oil cylinder, and the oil cylinders drive the corresponding pinch roll supports to rotate around the hinging points so as to drive the two pinch rolls to be relatively close to or relatively far away from each other.
The pinch roll is a water-cooled pinch roll, and the gear motor and the oil cylinder are both water-cooled.
Compared with the prior art, the utility model has the advantages that: the pinch roll complete device with the drive has the advantages of simple structure, convenience in operation, time and labor saving, and continuous production guarantee, and a casting blank can be removed in time.
Drawings
FIG. 1 is a schematic three-dimensional view of a belt-driven pinch roll unit according to an embodiment of the present utility model;
FIG. 2 is a three-dimensional schematic view of the other view of FIG. 1;
FIG. 3 is a top view of FIG. 1;
In the figure, a frame 1, a right water-cooling protection plate 2, a left water-cooling protection plate 3, a cylinder 4, a pinch roll support 5, a water-cooling bearing seat 6, a pinch roll 7, a speed reducing motor 8 and a disc spring group 9 are arranged.
Detailed Description
The utility model is described in further detail below with reference to the embodiments of the drawings.
As shown in fig. 1, 2 and 3, a pinch roll unit with driving function is provided in the lower roller region between the withdrawal and straightening machine and the fire cutting machine. The device comprises a rack 1, pinch roll brackets 5 are symmetrically arranged at the inlet of the rack 1, the pinch roll brackets 5 are respectively hinged with the rack 1, pinch rolls 7 which are vertically arranged are respectively arranged on the pinch roll brackets 5, and two ends of each pinch roll 7 are fixed on the pinch roll brackets 5 through water-cooling bearing seats 6. And a vertically arranged gear motor 8 is arranged below the pinch roll bracket 5 respectively, an output shaft of the gear motor 8 is fixedly connected with a rotating shaft of the pinch roll 7 through a disc spring group 9, the gear motor 8 drives the pinch roll 7 to run forward and backward, and then a casting blank can be removed in time. The two sides of the frame 1 are symmetrically provided with horizontal oil cylinders 4, and the extending ends of the oil cylinders 4 are fixedly connected with pinch roll brackets 5. The two oil cylinders 4 simultaneously drive the corresponding pinch roll supports 5 to drive the two pinch rolls 7 to be relatively close to or relatively far away from each other, so that the distance between the two pinch rolls 7 is adjusted, and the continuous casting billet production requirements of various specifications are met. The two sides of the frame 1 are symmetrically provided with water-cooling protection plates: the left water-cooling protection plate 3 and the right water-cooling protection plate 2 are arranged at the outlet of the pinch roll, so that high-temperature radiation to parts such as the stand 1 during continuous casting production is avoided, deformation of a steel structural member is prevented, and the service life of spare parts is prolonged.
