rig. 110 The invention relates to equipment for rolling mills of metallurgical plants, namely, devices for transferring (changing) rolls and rolling stands. A device for handling with partial use of a workshop crane is known. This device contains guides, which are a continuation of the supporting surfaces of the slab, and for the wind-driven hydraulic cylinder. During the mill operation, the new cage is installed by crane on the mentioned guides. The replaceable cage of the short-stroke hydraulic cylinders is advanced from the mill line by the amount necessary to separate the work rolls from the spindles of the drive, after which the spindle is removed by a crane. A new stand of long stroke hydrocyliidrome is moved along the guides to the mill line before the joining of its work rolls with the spindles of the drive 1. The closest to the proposed technical essence is the device for handling the stands, containing the mechanisms of transverse and longitudinal (relative to length, rolling) movement of the stands. This device is provided with a transfer trolley, which is installed parallel to the rolling line with the possibility of moving from a hydraulic cylinder to a turn exceeding the width of the cage. On the platform of the trolley there are stands for replaceable and new stands with guides that are aligned with the guides of the working line. The lateral movement of the stand, which is installed directly in the working line. The rod of this hydraulic cylinder is closed to the stand through a quick-disconnect hydraulic connection. The new cage is installed on one of the stands of the platform of the trolley with a crane during the operation of the mill. After stopping the mill, the replaceable stand of the long stroke hydraulic cylinder slides out of the line of the mill to the trolley platform, the cylinder of the hydraulic cylinder opens with the replaceable stand, the trolley is displaced in the longitudinal direction by more than the width of the stand. In this case, the new stand is installed exactly along the axis of the working line. The rod of the long stroke hydraulic cylinder closes with a new cage, and in its reverse direction, along the guides, the new cage is turned on to the workplace. The replaceable stand is removed from the platform stand of the trolley by the crane after the start of mill 2. However, installing the same trolley of the replaceable and new stands complicates the design of the cart, increases its intensity, and also increases the drive power and the cost of its movement. The purpose of the invention is to reduce the size and weight of the trolley of the mechanism for longitudinal movement during transshipment, mainly of large-size stands, due to the possibility of installing one group of stands on it. This goal is achieved. In a known device comprising a driving carriage of a mechanism for longitudinal movement of stands, a mechanism for transversely Moving one (replaceable or new) group of stands, and also a stand for an intermediate installation of one of the groups of stands, preferably a new one for an intermediate installation. it is stationary behind the mechanism of the longitudinal movement of the stands in the zone of action of the mechanism of the lateral movement of the stands. To simplify the construction, the mechanism for the lateral movement of the stands is made in the form of a trolley with grippers set above the size of the stands. FIG. 1 shows a device for transferring a group of stands to a general view; in fig. 2 same plan view; in fig. 3 shows section A-A in FIG. 1. The device consists of a mechanism for transverse movement of the stands, made in the form of a rolling line of the rack 1 located perpendicularly, on the guides of which a driving carriage 2 with grippers is mounted 3. The mechanism for longitudinal movement of the stands is made in the form of a driving carriage 4 mounted on rails located parallel to the line of rolling below the floor level. Under the overpass 1, the stands 5 of the trolleys 4 are placed stationary for stands 6, 7 and 8, 9, which are in working position connected to the drive 10. The device operates as follows. Before transferring the replaceable stands 6 and 7, the cart 2 is moved along the rails of guideway 1 on the LINE) rolling and is gripped and under the stands 6 and 7 of the hooks 3. After that, the cart 2 is moved to the longitudinal movement line and the stands 6 and 7 are mounted on the platform carts 4. Then cart 4 with stands 6 and 7 are displaced along rails beyond the envelope of rack 1, and cart 2 is moved to stand 5, where new stands 8 and 9 prepared for work are lifted by hooks 3, transported to the Rolling line and lowered onto plitoviny. The cart 4 is moved under the overpass 1, and the cart 2 is moved to the line of the longitudinal movement mechanism, where the grippers 3 lift the interchangeable stands 6 and 7. from the cart 4 and transport them to the stand 5. Any one of the stands in operation can be replaced in the described above order individually.
