Description

DEVICE FOR ASSEMBLY AND DISASSEMBLY OF ROLLING ROLLS

The device relates to mechanical assembly production and is intended for installation and dismantling of rolling rolls with pillows and bearings.

A device for assembling and disassembling the rolls 1 comprising a bed, in which a lifting table with a hydraulic drive is fixed, as well as annular hydraulic jacks mounted on the neck of the roll when pressing the bearings.

The disadvantage of this device is the large size and weight of the lifting table and the bed, the complexity of the design and difficult access when servicing the mechanisms of the table. Moreover, the presence of removable ring hydraulic jacks installed between the necks of the roll does not allow constructively simplifying the bed and the lifting table.

A device for assembling and disassembling the rolls 2, the design of which is taken as a prototype.

containing a lifting table mounted on the bed for installing a roll with cushions, as well as grips for roll cushions, and movable calipers with wrenches.

The disadvantage of this device is the large size and weight of the lifting table and the bed, the complexity of the design and difficult access when servicing the mechanisms of the table.

In addition, the arrangement of the table and the drive cylinder in a separate frame on the bed requires a table exhibition during installation.

The problem solved by the proposed utility model is to simplify the design, facilitate maintenance and installation by eliminating the middle part of the device.

This problem is solved as follows.

In a known device for assembling and disassembling rolling rolls comprising a lifting table mounted on a bed with a drive in the form of a hydraulic cylinder for installing a roll with pillows, as well as grips for roll pillows and movable calipers with wrenches, ACCORDING TO THE OFFER

the bed is made of two parts, and the lifting table is made in the form of two autonomous lifting supports mounted on the corresponding parts of the frame, the distance between which does not exceed the length of the roll barrel, and the hydraulic cylinders for lifting the supports are located in vertical bores at the ends of the frame parts.

Figure 1 of the drawing shows a General view of the proposed device.

The device consists of a frame made of two parts 1, 2, on the ends of which, facing each other in vertical bores 3, hydraulic cylinders 4, 5 are mounted, connected with bearings 6, 7 for rolls 8. On the parts of the frame 1, 2, rails 9 are mounted with wrenches 10, moving from hydraulic cylinders 11.

The distance between the supports 6, 7 does not exceed the length of the barrel roll 8.

The device operates as follows.

Before assembling the roll with the pillows, the supports 6, 7 are raised by the hydraulic cylinders 4, 5 to the upper position, the pillows are mounted on the slide 9, allotted to the extreme position.

Then, a roll is laid on the supports 6, 7 by a crane, after which they are lowered and centered with the axis of the pillows. The slide 9 with cushions and wrenches 10 is moved by hydraulic cylinders 11 to the supports 6, 7, the cushions are put on the neck of the roll and the wrenches 10 tighten the nuts and fix the pillows on the roll.

This design eliminates the middle part of the bed and the lifting table, which allows to reduce their size and provides free access to the hydraulic cylinders of the lifting supports and to their guides for maintenance.

The small size of the guides of the lifting supports allow them to be performed with high accuracy, reduce the gaps, distortions of the supports and the resistance when lifting them. The location of the supports and hydraulic cylinders in the bores of the frames excludes their exhibition during installation.
