    A device for replacement is known. rolls, in which the grip, located at the end of the moving rod, is made in the form of an open top slot for receiving the rolls I1}. The closest to the invention to the technical essence and the achieved result is a device for replacing the conical intermediate rolls in the multi-roll rolling stand by their axial movement, containing a movable rod, at the end of which the grip 23 is located. A disadvantage of the known devices is the difficulty of servicing due to the possible re-rolling of rolls. The purpose of the invention is to facilitate the maintenance of the device. The goal is achieved by the fact that in the device for replacing the tapered intermediate rolls in the multi-roll rolling stand by axial movement, containing a moving rod, at the end of which there is a gripper, made in the form of an open top bowl for receiving the rollers, the gripper is adapted for lateral movement perpendicular to the direction of movement of the and is equipped with a lateral displacement hydraulic cylinder, the body of which is an integral part of the gripper, and the piston is fixed to the shifting rod by means of a guide element, the gripper for two rolls being made common. FIG. 1 shows a multi-roll rolling stand, side view; in fig. 2 - intermediate roller with a device for replacing the rolls; in fig. 3 - the device at the time of fixing them an intermediate roll; in fig. “- the same, top view. The device for replacing the tapered intermediate rolls contains a moving rod 1, driven from the hydraulic cylinder 2. At the end of the rod 1, a guide 3 is fixed, with which the piston 5 of the hydraulic cylinder 6, which is in contact with the sliding surface 7 of the guide 3, is rigidly connected by means of the bar C. On the one side of the hydraulic cylinder 6, a grip 8 is attached, made in the form of a double bowl on top to receive intermediate rolls 9 through the bearing unit 10, having a groove 11. The device operates as follows. Before laying the new intermediate rolls 9, the hydraulic cylinder 6 is in the lower position. The rolls 9 are placed in the cage, due to the hydraulic cylinder 2, the rod 1 is extended, and the rollers 9 are aligned relative to each other in the axial direction, after which the hydraulic cylinder 6 transversely moves the gripper 8 and inserts it into the groove 11 of the bearing assembly 10. During installation of the rolls 9 In the cage by the hydraulic cylinder 2, their vertical position is carried out by the hydraulic cylinder 6. After installation of the rolls 9, the gripper 8 is lowered, released from the engagement with the groove 11 and removed by the rod 1 from the cage. The operations described above can be controlled by air from a control panel 99. 4 The invention facilitates the installation of intermediate rollers and thus reduces the time for their replacement. The invention The device for replacing tapered intermediate rolls in a multi-roll rolling stand by their axial movement, containing a shifting rod, at the end of which there is a gripper, made in the form of an open bowl for receiving the rollers, which, in order to facilitate maintenance, made with the possibility of lateral movement, perpendicular to the direction of movement of the shifting rod, and provided with a hydraulic cylinder of lateral movement, the body of which is an integral part ahvata, a piston rod fastened to pass through the guide member, wherein two rolls zahaat made common.
