Description

The invention relates to mechanical assembly work and may find application for disassembling the assembly of large-sized products, for example, in the repair of household units for drying flax N of other agricultural crops.

The purpose of the invention is the expansion of technological capabilities by providing assembly - disassembly of products such as furnace units.

The drawing shows the proposed device, a General view.

The stand contains a base 1, fixed on the foundation with anchor bolts. On the base I, the support 2 is fixed, along the guides of which the console 3 moves in the vertical direction under the action of the hydraulic cylinder 4, and in the horizontal plane under the action of the power cylinder 5. On the console 3 there is a washer b with connecting elements (bolts) and a centering mechanism made in the form of a lever 7 with a roller 8 controlled by a hydraulic cylinder 9. On the base 1 there is also installed a trolley 10 having an electromechanical drive and moving on wheels along the console 3 on which there are two carriages P, s adjustable supports 12. Ka-move in the direction perpendicular to the direction of the Telle movement, screw pairs and independently of each other.

The stand works as follows

The covered large-sized part 13 is mounted on supports 12. The console 3 is mounted by the hydraulic cylinder 4 along the axis of the part 13. The trolley 10 is moved to the left on the console 3 until the flange of the part 13 touches the shabby 6. The cup is bolted with the part 13. The speed bracket 7 is set to contact of the roller 8 with the inner surface of the part 13. The console 3 together with the part 13 fixed on it under the action of the hydraulic cylinder 4 rises up after h

The Yu truck moves to the extreme right. Adjustable supports 12 are installed in a position corresponding to the details of a larger diameter.

Mr. unit.

a large, large piece .14, Part 13, mounted on the console 3, is positioned along the axis of the part 14. The cart 10 moves to the left on the console 3 until the part 13 is fully inserted inside the part 14, while keeping in mind the relative position the latter and, if necessary, centering using hydraulic cylinders 4 and 9 and moving the carriages 11 in a horizontal plane. The final centering of the bolts welded into the connecting flange 15 relative to the openings of the flange 16 is achieved by moving the right carriage 11 and changing the position of the lever 7.

When centering is achieved, under the action of the ram 5, the bolts are inserted into the holes and all connections fixing the relative position of the parts 13 and 14 are tightened. The bolts connecting the washer 6 to the part 13 are screwed off, the lever 7 is lowered to the lower position and the car 10 s the assembled bulky product is rolled back to the right extreme position.

The product is disassembled in reverse order.

The use of a prototype wall –– while repairing the TAU-0.75 furnace units — reduces the labor intensity of the disassembly and assembly work by more than 2.5 times, and such operations as removing the combustion chamber from the exchanger and heat exchanger from the housing and its reverse, do not deviate from safety requirements. The development of the stand makes it possible to organize the repair of heating units, and to get a national-economic effect of more than 1000 rubles. on each. repaired
