SU55092A1 - Machine with circular saws located in vertical and horizontal planes for cutting out paving blocks from arrays - Google Patents

Description

The proposed machine is intended for cutting stone blocks from rock massifs, for example, talc-magnesite stone used as refractories, directly in the bottom, and equipped with circular saws for this, located in both vertical and horizontal planes.

It differs from the already known machines of this kind in that, in order to support the paving stones during operation from the collapse, a special supporting disk is mounted on the horizontal shaft of vertical saws and, moreover, a frame with slots for the passage of vertical circular saws is mounted on the machine bracket. and supporting disk.

The accompanying drawing shows schematically an exemplary embodiment of the proposed machine, with FIG. 1 shows a front view thereof; FIG. 2 at the side, FIG. 3 - in the plan.

On three ramps / wheels, there is a rivet frame 2, on which a motor of the closed type 3 is mounted, which drives the transmission shaft 4, on which three cylindrical gears 5, 6 are seated. 7. Gear 5 interlocks with gear wheel 8, which sits on a horizontal shaft 9, and sets in motion through a pair of bevel gears 10 and 11 two circular saw blades 12, mounted on a vertical shaft 13 at a small distance from each other and cutting to a certain depth along the whole front of work.

A vertical shaft 13 is fixed at the end of the movable frame 14, on which a horizontal shaft 9 is placed. The frame 14 is fixed in the frame 15 and. has mobility in the horizontal plane using the handwheel 16, which achieves precise regulation of the horizontal cut when the discs are worn.

The gear 6 engages a spur gear 17 mounted on a shaft 5 and interlocks with a parasitic spur gear 19 mounted on the lever 20. The gear 19 engages a gear 21 rotating horizontal

shaft 22, on which four circular saws 23 are mounted at some distance from each other, cutting in a vertical plane along the whole front of work.

On the horizontal shaft 22, another disk 2 is fastened, which serves to support the paving stones from the dam during the working process. To avoid settling paving stones on the thickness of the cut horizontal discs during operation is the frame 25, attached to the bracket 2o. The frame has slots for passing the saws 23 and the vertical disk 24 and goes simultaneously to the horizontal cut. When discs are worn, the regulation of the vertical cut to a certain depth is achieved by using the handwheel 30 by lowering or raising the bearings 27 in the frame 28 attached to the channel beams 29.

The machine moves along a narrow rail track along the bottom by means of a winch, rotated from the transmission shaft 4 through gear 7, coupled with a cylindrical gear gear 31, which rotates the worm gear 32. the gear 37 mounted on the shaft 38. In addition to the latter, gears 38, 39, 40 are seated on the 3S shaft, which makes it possible to obtain different speeds of advancement of the machine during operation.

The cutting speed is adjusted by lowering or raising the handle # / and the handwheel 42.

A drum 43 is mounted on the shaft 36, to which a rope 44 is attached with one CBOHJVI end. To avoid stopping the motor and breaking parts of the machine during operation, when it encounters stronger rocks, a friction clutch 45 is mounted on the same shaft with the drum; rope gives slippage.

To prevent the machine from tilting during operation, it is supplied from the front and rear side with guide rollers 46 moving along the edges of the rails. The machine is set at an angle to the horizon.

The subject matter of the invention.

A machine with circular saws located in vertical and horizontal planes for cutting out paving blocks from arrays, characterized in that in order to keep the pavement during sawing from collapse, a disk 24 is mounted on the horizontal shaft 22 of the vertical saws 23 and on the bracket 26 The frame 25 is reinforced with slots for the passage of the saws 23 and the disk 24.
