Description

Изобретение относится к черной металлургии и может быть использовано в прокатных цехах металлургических заводов для обслуживания подшипниковых узлов валков прокатных станов.The invention relates to ferrous metallurgy and can be used in rolling shops of metallurgical plants for servicing bearing assemblies of rolls of rolling mills.

Известен кантователь подшипниковых ⁵узлов прокатных валков, содержащий платформу, с двух противоположных сторон которой расположены вертикальные кантующие щеки, снабженные элемента— ми фиксирования подшипниковых узлов [1].Known tilt bearing ⁵ nodes of the rolling rolls, containing a platform, on two opposite sides of which are vertical turning cheeks equipped with elements for fixing the bearing assemblies [1].

Однако известный кантователь не обеспечивает быструю и удобную установку кантуемых узлов различных типоразмеров при минимальном количестве смен— ных крепежных деталей и приспособлений. Кроме того, сам кантователь занят на протяжении всего времени обслуживания подшипникового узла.However, the well-known tilter does not provide quick and convenient installation of canted knots of various sizes with a minimum number of replaceable fasteners and accessories. In addition, the tilter itself is busy throughout the entire service life of the bearing assembly.

Целью изобретения является увеличе— _мние типоразмера кантуемых подшипниковых узлов.The invention aims _m An increase of the size kantuemyh bearing assemblies.

Цель достигается тем, что каждая из щек установлена с возможностью го— ризонтального перемещения относительно платформ вдоль оси кантовки, а платформа выполнена в виде подъемного стола, снабженного опорной плитой, установленной с возможностью ее перемещения относительно стола в горизонтальной плоскости в направлении, перпендикулярном к горизонтальному перемещению щек кантователя.The goal is achieved in that each of the cheeks is installed with the possibility of horizontal movement relative to the platforms along the axis of the tilting, and the platform is made in the form of a lifting table equipped with a base plate installed with the possibility of its movement relative to the table in a horizontal plane in a direction perpendicular to horizontal movement tilter cheeks.

Подшипниковый узел 1, боковые поверхности которого имеют два отверстия А, устанавливают грузоподъемным средством, например краном, на опорную плиту 8. подъемно—опускающегося стола 3, находящегося в исходном нижнем положении. Включается привод 15 перемещения щек 12, которые выравнивают подшипниковый узел 1; подпружиненные штыри 16 при этом утопают в щеках 12. Приводом 10 совмещаются вертикальные, а приводом 7 горизонтальные оси отверстий А и штырей 16, причем последние, освобождаясь, входят в эти« отверстия.. Далее стол 3 опускается в исходное нижнее положение, а подшипниковый узел остается висеть на штырях 16, зажатый между щеками .12 и подготовленный к кантовке в любом направлении.Bearing unit 1, the side surfaces of which have two holes A, are installed by lifting means, for example, a crane, onto the base plate 8. of the lifting-lowering table 3, which is in the initial lower position. The drive 15 moves the cheeks 12, which align the bearing assembly 1; the spring-loaded pins 16 are buried in the cheeks 12. With the drive 10, the vertical and the axis 7 of the holes A and pins 16 are combined, the latter being released into these "holes. Next, table 3 is lowered to its original lower position, and the bearing assembly it remains to hang on pins 16, sandwiched between the cheeks .12 and prepared for tilting in any direction.

Known tilter bearing assemblies of rolling rolls, containing a platform, on two opposite sides of which are vertical tilting cheeks, equipped with fixing elements for bearing units IjlJ In addition, the tilter itself is occupied throughout the entire service time of the bearing assembly. The aim of the invention is to increase the size of the turning-in bearing units. The goal is achieved by the fact that each of the cheeks is mounted with the possibility of horizontal movement relative to the platforms along the axis of turning, and the platform is made in the form of a lifting table equipped with a support plate installed with the possibility of moving it relative to the table in a horizontal plane in a direction perpendicular to the horizontal plane. move cheeks tilter. Fig, 1 shows the proposed tilter; in fig. 2 - the same, end view. The tilter bearing units 1 consists of a frame 2, the platform of which is made in the form of lifting angle 3 on the rails 4. On the frame 2 there are two tilting levers 5 on independent hinges 6 having a common axis of rotation. Table 3 is located in the turning zone between the hinges 6 and is moved by the drive 7. Table 3 is provided with a support plate 8 placed on a roller separator 9 and connected to the drive 10, which provides movement of the plate 8 in a horizontal plane perpendicular to the axis of the hinges 6. Ry the chagas 5 are connected with a drive of their rotation, made tia four in pairs from the united cylinder 11, and equipped with cheeks 12 fixed on the guides 13 and the hubs 14 of the hinges 6. The cheeks are connected with the drive 15 and carry the mounting elements of the tangent bearing node 1 as sprung joints 1-6. In frame 2, for fixing the levers 5, there are placed the speed-strut 17. The tilter works as follows. . The bearing unit 1, the side surfaces of which have two openings A, is set by load-lifting media. by means of a crane, for example, on a base plate of a 8. lifting and lowering table 3, which is in its initial position. The actuator 15 moves the cheeks 12, which align with the hip unit 1; The spring-loaded pins 16 in this case are buried in the cheeks 12. The 1O actuator combines the vertical ones, and the 7 axes of the holes A and the pins 16 are combined by the actuator 7, the latter, being released, enter these holes. Then the table 3 descends to its initial lower position , and the CU bearing unit hangs on pins x 16, sandwiched between the cheeks 12 and prepared for turning in any direction. Depending on the direction of turnoff, a pair of cylinders 11 are included, located on one side of the axis (the second pair is idling). The node 1 scanned to 9O is weighed by the actuator 7 of table 3, and by means of 15, the cheeks 12 are retracted and the pins 16 are withdrawn from the opening A, Table 3 oiiyc "together, cf. the scaffold to the initial lower position.
