Description

In the known machines for cutting directly from a rock of the correct shape, equipped with a series of endless chainsaws moving in vertical and horizontal directions, the inventor proposes to use a rod with teeth or cones attached to the saw planes at right angles to the saw planes. for rotation thrown by endless chain saws through them, and for horizontal and vertical movements of the cutting device - a device consisting of a carriage, moved and opus tangency gear, coupled to the rack through a chain transmission to the handwheel.

In FIG. 1 shows a perspective view of a car; FIG. 2 is a side view of the front of the cutting device; FIG. 3 is a partial view from above.

The proposed machine for cutting directly from the rock of regular-shaped stones consists of a bed 1 supported on the base 2 of angular iron, and for the lateral movement of the machine the base 2 has two pairs of wheels b, sitting on common

axles, and for translational movement, two wide wheels 7. For the transition from lateral movement of the machine to the translational wheel 7, they are connected to the base 2 by levers 8, which are connected by pairs of rods 9 with screws 10, by rotation of which the levers 8 are driven from an inclined position in close to vertical, and, therefore, lowering the wheels 7 on the floor, you can lift the whole car with wheels 6 upwards. The rotation of the screws 10 is carried out by the handwheel 14, which is connected by a chain gear 12 to the shaft 13, and the latter, in turn, by a chain gear 11 with a screw 10. The machine is oriented by a guide beam 15 with a fixture for abutment into side walls consisting of 16 with the fists 17 and the lever 18, when shifted, the fists 17. The beam 15 is enclosed by an angled iron 19, fastened at right angles to the angular iron 20 of the base 2. The bed 1 is provided with a frame 21 of the angled iron with rollers 22 and guides brackets 23, suspended oh on chains 24 from the pulling toothed wheel 25 at the top and bottom of the drive toothed wheel 26. The latter sit in pairs on axle x27, rotated with handwheel 28 via chain drives 29 and 30. Frame 21 is connected to carriage 5, which has a cutting part at one end and 31 (motor) counterweight at the other. In the middle, approximately et center of the carriage of the carriage 5, there are wheels 32 moving along the underside of the corner of the frame 21, and through the slots of the brackets 23 passes the shaft 33, on each side of which there is a roller 34 rolling along the notch and a gear 35 engaging the toothed rail 36, the straight parts of which are connected by half of a circle. The shaft 33 rotates with the aid of the handwheel 37 with a chain drive 38.

The cutting part 4 consists of a channel 39 with brackets 40 fixed on it, which are connected at the ends

- with an asterisk 42, bearings 41 (FIG. 2), which carry a chain 43 of one form or another, and in their center there is an opening for securing the rollers 44 C, respectively, with a treated cutting surface. On the channel 39 in bearings there is a shaft 45 with gears 46 and a gear 47, connected by a chain 48 with a motor 31,

To operate the machine, the frame 21 is lowered to the lower position with a carriage 5, the last handwheel 37 moves forward, and the cutting part 4 cuts into the rock, the cutter section 44 of the lower surface of the stone. Upon reaching the desired recess, a vertical movement is provided to the carriage and the rear (by means of the cones) and lateral (cutting wheels, T1 mi) stone surfaces are separated. Then the carriage y is stopped and she moves back and

separates the upper surface of the stone, and in order to prevent the separation of the stone, the rail is laid in time in the lower slot. The stones remain in place and the kerfs continue from the bottom up, with the carriage changing its inclination before the last stone by tilting the shaft 33 into the lower slots of the bracket 23, which makes it possible to produce the upper kerf above the frame. The machine is then lowered onto the transverse wheels, shifted to the side and the new cuts begin again from the bottom, and the stones that were cut before are removed. Then, the machine goes back, moves forward the width of the stone, re-fixes itself with an emphasis on the ceiling, and then the beam 15 is released and moves forward.

The subject matter of the invention.

1. A machine for cutting directly from a rock of regular shape, having a series of endless chainsaws that can move both vertically and horizontally, using a rod with teeth or cones 44, which is located at right angles to the planes of saws, reinforced in asterisks 42 brought into rotation by endless chainsaws thrown over them 43.

2. In the machine specified in clause 1, a device for communicating horizontal and vertical movements to the cutting device, consisting of a carriage 5, movable and lowered by means of a rack 35, engaged with a gear rack 36 by means of a chain transmission 38 and a flywheel 37.
