Abstract

Usage: in drum mills for grinding materials. SUMMARY OF THE INVENTION: The device comprises a support 1 that guides 1 on the power cylinders and a support frame 4 mounted on them with rollers 7. The shoes 6 are mounted on the support frame 4. The guides 1 are arranged perpendicular to the axis of rotation of the mill. One end of each rail is equipped with a hinge support 3. 1 cf f-crystals, 2 ill.

Description

The invention relates to devices for dismounting the shoes of large-sized sliding supports, e.g. rotary grinding drum supports.

A device for dismounting heavy shoes of large-sized sliding supports is known, comprising guides supported on a lifting device, which in turn are supported by special supporting vehicles, by means of which the shoes move along the guides in the direction of the mill.

A disadvantage of this device is: the use of large production areas; increasing labor costs for disassembling the adjacent drum assemblies located along the axis of the mill and hindering the dismounting of the shoes by their movement along rails; cumbersome design, especially when using supports with a distributed load on the shoes, where the shoes are more than one on each side

drum, and for their dismantling required guides for each shoe.

The aim of the invention is to reduce the metal consumption and save production space.

The goal is achieved by the fact that, in a device for dismounting the shoes of large-sized slide bearings of drum mills, consisting of guides supported on power cylinders, rollers mounted on them and a support frame on which the shoes are mounted perpendicular to the axis of rotation of the mill mounted on a support frame. One end of each rail is provided with a pivot bearing.

Fig. 1 schematically shows a device for dismantling heavy shoes of large-sized sliding supports; figure 2 - section aa in figure 1.

The device has guides 1 located perpendicular to the axis of rotation of the mill (drum mill

1 is represented by a dash-dotted line) and rests on one side on the power cylinders 2, on the other - on the hinge support 3. On the support frame 4 mounted on the hinge support 5 and serving to distribute the load from the support shoes 6, on which the turn is supported by a drum mill, there are rollers 7.

The device works as follows.

In the elevated position of the drum, the power cylinder 2 raises the thrust guide-1 supported by the hinge support 3 until it comes into contact with the rollers 7 mounted on the support frame 4 and lifts the rollers with the frame until frame 4 is free from the hinge support 5. Then, by driving the rollers 7, the frame 4 is moved along the guide 1 in the direction perpendicular to the axis of rotation of the drum.

The advantages of the solution are that the device is simple in construction, it requires half as many power cylinders, besides along two guides

it is possible to remove several shoes at once, which makes it possible to apply this device on supports with a distributed load. Economy ts production area, since the device is more compact, and when dismounting the shoes using the device, it is not necessary to disassemble the assemblies adjacent to the drum.
