The invention relates to rolling production, namely, devices for Assembly and disassembly of pillows rolls.

Known stand for disassembly and Assembly of rolls with bearings (pillow), sostojashie is led by the rotation of the auxiliary drive. However, due to the lack of offline travel drive trucks pillows and availability of manual operations hitch - recepce truck wrenches with trucks pillows stand has low productivity and narrow technological capabilities. (Chub E. F. Oversized pillows rolling. M; mechanical engineering, 1976, S. 239).

Known stand containing a movable frame with a platform for mounting the shaft, coaxially guides located on both sides of the movable frame carrying the movable sled with the gripping elements in the form of cylinders, and the carriage with hydraulic cylinders mounting and Dismounting of pillows and wrenches, are equipped with two shoulders hinge arms for gripping nuts [1].

However, this stand has limited technological capabilities, as provided by Assembly and disassembly of pillows rolls only one size.

The purpose of the invention is to create a stand with advanced technological capabilities at the expense of Assembly and disassembly of pillows of various sizes.

To do this, stand for the Assembly and disassembly of pillows rolls, comprising a movable frame, coaxially guides, supporting mobile platforms with clamps, and the soup is AMI for gripping nuts, equipped with hydraulic cylinders capture nuts, rods are placed in the cylinders mounting and Dismounting of pillows, made hollow, and is equipped with control bushings; interacting with two shoulders articulated levers made spring-loaded, each of the wrenches are equipped with valves and spring-loaded stops interacting with the control sleeve, with the movable platform with clamps supplied with hydraulic cylinders move performed a multi-way, and the tabs are cylinders made as well multi-way.

In addition, the kinematic connection of each of the valves with the control sleeve is made in the form of a rocker arm communicating at one end with a wing, and the other with the control sleeve by means of a spring-loaded stops.

In Fig. 1 shows the stand; Fig. 2 is a view along arrow a in Fig. 1.

The stand is composed of a movable frame 1, coaxially of the guides 2, located on both sides of the moving frame and movable bearing platforms 3 with 4 tabs, hydraulic cylinders 5 and calipers 6 cylinders 7 mounting and Dismounting of the cushions 8 and wrenches 9, equipped with two shoulders hinge arms 10 for gripping nuts 11.

The kinematic connection of each of the valves 16 with the control sleeve 15 is made in the form of a rocker arm 18 that communicates at one end with a wing, and the other with the control sleeve by means of a spring-loaded stop 17.

For lifting and lowering the platform provides for a combined actuator, consisting of a hydraulic cylinder 19 and the motor 20 with the gear pair and the anchor nut. In addition, the movable platform 3 with the tabs 4 are supplied by the hydraulic cylinders 21 movements made multi-way, and the tabs 4 are rods of the hydraulic cylinders 5, also performed a multi-way.

For movement of the carriage 6 with wrenches 9 provided by the hydraulic cylinders 22 and to rotate the ratchets 9 - motors 23.

For mounting and Dismounting of the pillow 8 is provided with the thrust 24 with holes, rigidly United with wrenches 9.

Stand dismantling support roll works as follows. Roll in what atom, to the axis of the clamps 4, made in the form of cylinders 5, mounted on the platform 3, coincident with the axes of the holes to grip on the pillow 8.

The hydraulic cylinder 19 gland platform rises until it stops in a barrel roll. From the motor 20 through the tubular couple of anchor nut rises until it stops in the roll barrel to reset the pressure in the hydraulic cylinder 19 of the lifting frame.

Calipers 6 wrenches 9 under the action of hydraulic cylinders 22 are moved toward the axis of the moving frame to contact the ends of the cylinders 7 installation and dismantling of pillows with the ends of the roll.

Under the action HZ 12 by diversion of his rod back is the coverage of the nut teeth two shoulders of the levers 10. Included drives 23 wrenches 9 and the teeth of the levers 10 are in the slots of the nuts 11. Enables the actuator 23 of rotation of the ratchets 9 on breakout and nuts 11 go with thread roll inward wrenches 9.

When the extension rod of the hydraulic cylinder 12 and the impact of the control sleeve 15 on the two shoulders of the hinge spring arms 10 is the release of the nuts 11 on the coverage of these levers, and the feedback control sleeve 15 on the spring-loaded lugs 17 is sinking the last and closing STV is S="ptx2">

Calipers 6 wrenches 9 HZ and 12 are discharged from the axis of the movable frame 1 in a position in which the same axis clamps 4 cylinders 5 and the axis of the rod holes 24 calipers 6. The latter is provided with automation.

The cylinders 5 tabs 4 are inserted into holes pillows 8 through the corresponding holes of the rods 24.

For Assembly - disassembly pillows back-up rolls of various sizes are used multi-way hydraulic cylinders, providing a different length depending on the sizes of the progress of the clamps 4, made in the form of cylinders 5.

Next, select the stroke of the hydraulic cylinders 7, and then the hydraulic cylinders 22 move the calipers. After returning multi-cylinders 21 3 platforms together with removed from the roll pillows 8 in the source, far from the position of the moving frame are 4 tabs from the holes of the cushions 8 and rod 24 by retracting cylinders 5, freeing the latter.

The cylinders 21 of the moving platform 3 is made of a multi-way to achieve the same purpose - maintenance of rolls of various sizes.

Calipers 6 wrenches 9 discharged by the hydraulic cylinders 22 from 3 platforms in Isha disassembly and Assembly, or after inspection are used for Assembly with peretochennym roller.

The design of the stand provides automation of technological operations. The support roll Assembly with pillows is in the reverse sequence.

The introduction of the proposed technical solution will solve the problem of maintenance of pillows rolls of various sizes.
