(54) DEVICE TO STONE-CUTTING MACHINE FOR TIPPING

BLOCKS

one

The invention relates to a stone-cutting technique, in particular, to a backward stone-cutting machine for cutting large blocks of stone.

The famous stone cutting mgpina for cutting large blocks of stone, consisting of a wheel frame, a cart, a drive, cutting members and a rope with a hook for tipping the block. .

The disadvantage of this machine is the use of manual labor when placing a hook for tipping over the Propyl and holding it manually until the necessary tension of the rope.

It is also known a device for removing a cut stone from the bottom, mounted on an independent frame on rollers moving along the side of the track, characterized in that the device includes a gripping body in the form of a hook, snarling-pull cable system connected to the hydraulic cylinder and chain conveyor 2J.

The drawbacks of this device are the need for an additional entry trench for placing it at the beginning of the bottom, a large intensity and complexity of the design.

The purpose of the invention is to improve the quality of the sawed-off blocks and increase the productivity of the proposed device to a stone-cutting machine for tipping blocks.

This goal is achieved by the fact that the rotation mechanism is made in the form of a stop and a figure lever pivotally connected to it, installed with the possibility of rotation in a vertical plane, in addition, the traverse and the rotation mechanism are equipped with automatic control sensors, made in the form of stops

5 with contactors.

FIG. 1 shows the proposed device, a general view; in Fig. 2, section A-A in Fig. 1; in fig. 3 node I in FIG.

The device consists of a traverse 1, with a probe 2, mounted on a trolley of stone-cutting machine 3, a lifting lever 4, controlled by a hydraulic cylinder 5 and a turning mechanism

5 blocks, including stops b and a figured lever 7, the latter being pivotally fixed with the possibility of rotation in the plane perpendicular to the plane of the vertical longitudinal cut with the help of a hydraulic cylinder

8 and the hydraulic control sensors of the rotation mechanism of the blocks 9 and 10, including the stops 11 and the contactors 12.

The device works as follows.

When the crosspiece 1 is installed in its original position for the production of longitudinal vertical cutting 13, the mechanism for rotating the blocks is also installed above the line of the longitudinal vertical cutting, while the lever 4 is held by the hydraulic cylinder 5 in the upper position. When moving the traverse forward in the production of longitudinal cutting, the probe 2 slides on the surface of the ledge and when hit in the transverse cutting, turning under the action of the spring closes the contacts 12, resulting in a hydraulic actuator (not shown) receives the command and the hydraulic cylinder 5, turning the lever 4 around axis down in a vertical plane, inserts the closed ends of the stop 6 and the lever 7 into the cut 13, after which the probe 9 closes the contacts, the hydraulic actuator receives a command and actuates the hydraulic cylinder 8 (FIG. 4), which rotates the lever 7 and tilting block 14 is driven. At the end of the stroke of the lever 7, the contacts 10 are closed and the hydraulic actuator receives a command, as a result of which the hydraulic cylinder 8 rotates the lever 7,

and the hydraulic cylinder 5, the lever 4 to its initial positions. When tilting a block, the force acts only on the block and the ledge, without affecting the linearity of the movement of the machine itself.
