Description

i

The invention relates to the black metallurgy and is intended for use in steelmaking when servicing steel-teeming ladles with slide gates.

A device is known which comprises a hydraulic cylinder, the through rod of which serves as a guide for moving in the vertical direction the hinge links with a platform for fastening.

When servicing bucket with slide. gates, the link on which there is a platform is brought under the gate. The bolt is disconnected from the bucket, using the hydraulic cylinder, lowering the links with the bolt and diverting the valve to the operating zone of the crane, which is used to remove the bolt. Then install a new valve with a crane. The operations of putting the slide on the bucket are performed in the reverse order.

It is also known a device for preparing a bucket with slide gates, containing a vertical column with rotating supports, in which guides are located, connected through a bracket to a cylinder of vertical movement, the rod of which is pivotally connected to the slide and carriage with the supporting platform 2.

A disadvantage of the known devices is the duration of servicing the bucket due to the fact that it is necessary for the crane to first remove the worn gate and then only a new one can be delivered. This requires additional space to install more devices in order to ensure timely bucket preparation. In addition, when the valve is mounted on the bucket, the vertical movement is connected by hinge links with the valve, which also impairs the maintenance of the bucket.

five

The purpose of the invention is to reduce the preparation time of the bucket.

This goal is achieved by the fact that the device is equipped with a movable rack.

0 consisting of a frame on which stops are fixed for fixing the slide gate and one of the support links, while on the hydraulic cylinder rod there is an additional area for opening the slide.

FIG. 1 shows schematically the device, a general view; in fig. 2 the same in terms of.

Claims (2)

The device consists of a vertical column 1 and a support 2 mounted on it with hinge links 3 and 4, a hydraulic cylinder 5 fixed at the end of a hinge link 4. The rod of a hydraulic cylinder 5 ends with a pad b. The structure, the device also includes a mobile rack 7 ,. the frame of which is fitted with stops 8 for fixing ™ poydonov 9 with slide gates and 10 without closures, stops 11 are for fixing the hinge link 4. The working fluid from hydraulic drive 12 is supplied to cylinder 5 through pipelines and sleeves 13 and 14. For performing the operation by about Serving the bucket, the latter is installed on Stand 15. The operation of the device is as follows. On the movable rack 7, one pallet 9 with slide gates is installed, and the other 10 is installed without gates. With the help of stops 8 pallets fixed with on the rack. Then, the casting ladle with used slide gates (shown on the figures with thin lines; mounted on stand 15 with a crane. Support 2 with hinged links 3 and 4 is turned around column 1 so that the axis of the hydraulic cylinder 5 coincides with the axis of the shutter on the bucket. The hydraulic drive is turned on 12, approach the platform 6 under; the gate valve and knock out a wedder holding it on the ladle. Then the shutter is lowered a little, the whole system is expanded relative to column 1, the hinge link 4 is inserted into the notch on the pallet 10 and the shutter is lowered until When removing the hinge link 4 from the bottom of the pan, it rests against the stop 11, and the rack moves to such a position that it is possible to install a second waste into the tray:. Shutter. When the hinge link 4 is removed from under the pallet 10 after the second spent valve has been installed on it, it rests on another stop, 11 and moves the rack further, then the support 2, links 3 and 4 with the hydraulic cylinder 5 are turned to remove the new valve from the pallet. When the shutter is removed, the link 4 is in contact with the stop 11 and moves the rack. The bolt is hung on the bucket in the reverse order of its removal. After installing the valves on the bucket, it is removed from the stand 15 and sent for further processing. The pallet 10 with waste valves is removed from the rack, and in its place another pallet is installed with new valves. At the same time, the pallet 10 with new closures is on the other side of the rack. Then another bucket is placed on the stand with the used shutters, and the operations are repeated. The use of this device allows to reduce the time for installation of new valves on the bucket, to reduce the number of crane operations associated with the supply and cleaning of the valves to the bucket, to simplify the design of the device, which allows you to have fewer devices in return, and to improve service of the buckets. Claims An apparatus for preparing a bucket with a slide gate, comprising a column on which a support with hinged links is mounted, and a hydraulic cylinder, characterized in that, in order to shorten the preparation time of the bucket, it is equipped with an installed: - movable rack consisting of from the frame on which the stops for fixing the slide gate and one of the support links are fixed, while a pad for placing the shutter is installed on the cylinder of the hydraulic cylinder.
