Description

In the author's certificate No. 30240, a stone cutting machine from arrays, consisting of a vertical frame mounted on a trolley moved by means of track belts, is equipped. On this frame, the drills can be moved in the vertical direction, driven by engines. To cut the stones, use band saws with cutters, re-cast: through drills located in the holder along the vertical and horizon 1-side sides of the semi-frames, which are moved by two screws to move along the fixed frame. In the case of enacted movement, cutting of the back side of the stones with cutting saws occurs.

In the proposed modification of the machine for longitudinal vertical cuts, frames with rope or chain saws, or drills are used, and for working of saws or drills below the rail level on the carriage, guides are installed to move the common frame using a handwheel with a screw.

In the drawing of FIG. 1 depicts the view of the machine c6oky; FIG. 2 is a view from above; FIG. 3 is a front view of it; FIG. 4 is a side view of the mechanism with a chain saw for vertical, tangled, longitudinal cuts of the chain saw; FIG. same, front view; FIG. 5 side view of the maschina with. drills instead of saws; FIG. 6 same, view from above; FIG. 7 is the same, front view; FIG. 8 is a view of the mechanism with a drill for vertical longitudinal cuts.

The essence of the proposed mashina (Fig. 1-3) is as follows. Guides 2 are attached to the carriage 7 moving along the rails laid parallel to the ledge of the quarry, in which the frame 3 can be moved vertically using a handwheel with screw 4. The frame 3 is provided with a shaft 5, which is rotated by means of a shaft 6 connected by Hooke -one by its end with motor 7 and the other with said shaft 5. From the last shaft, rotation is transmitted using a pair of conical gears 8

(FIGS. 2, 3, 6 and 7) to the driving units 9, through which JO flexible or chain saws are thrown. Other supports of flexible or chain saws JO are guide blocks 7 /, the diameter of which is much smaller than the diameter of the leading blocks I, since the latter are usually found in the developed part of the rock, and blocks 7 / during movement of the carriage 7 in the direction of arrow A (Fig. 2 , 3, b, and 7) are in the channel made by the drill 72.

For vertical longitudinal cuts (in the direction of movement of the carriage) are mechanisms, one of which; Presented on fip 4. The essence of the work of this; The mechanism is as follows. From shaft 5, when the chain transmission J3 rotates, the shaft J4, on which the blocks 75 sit, gives movement to the flexible or chain saws 76, turns. The tension of the saw 76 is achieved by rotating the screw 7y acting on the block 78. To move the mechanism for vertical cut, the width of the latter should be a little more than the thickness of the mechanism.

FIG. 5, 6, and 7 depict a machine for the purpose of also cutting rock into a piece of stone, but the difference between this machine and that shown in FIG. 1, 2 and 3 is provided in another arrangement of the mechanism for vertical rod sawing. The essence of this ahajaizm is tsdm that for

Vertical cuts are used drill 79 (Fig. 5 and 8), rotated using a pair of bevel gears 20, and all the leading bevel gears sit on the same shaft 5 (Fig. 8).

In addition to horizontal and vertical longitudinal cuts, vertical transverse cuts are made in the massif; the latter are made by chain or JO JOH while lifting the frame when the cart 7 is stopped. A cross-cut operation can also be carried out by a stand-alone trolley similar to the cart 7. In this case, the frame J will carry only chain or flexible saws 70, or and finally, only drills that can move in the plane of the cross cut.

P, r eet and 3 about b ete n and

Modification of a stone cutting machine according to copyright testimony JVfe 30240, characterized in that for longitudinal vertical cuts there are frames with cable or chain saws J6 (Fig. 3 and 4), tensioned on pulleys 75 and J8, or J9 drills (Fig. 7 and 8), instead of ppl 76, for operating saws or drills below the level of the rails, guide carriages of the total frame 5 are installed on the carriage using the handwheel with screw 4 (Figs. 1, 2, 5 and 6).
