Abstract

The invention relates to the mining industry, in particular to equipment for the extraction of blocks of natural stone. The goal is to reduce the cost of work on the extraction of blocks by reducing the consumption of free abrasive and water, while at the same time increasing the reliability of the stone-cutting machine. It contains a chassis with a drive for moving it. On the undercarriage there are guiding pulleys for the sawn cable and the drive of the working element with the engine. The latter is made in the form of a kinematically connected shaft with the flywheel attached to the shaft ends. The working body is made in the form of a piece of saw rope, the ends of which are fixed on the outer end surface of the corresponding flywheel. The ends of the saw rope are diametrically opposite and at the same distance from the longitudinal axis of the shaft. When the shaft rotates, the sawn rope reciprocates and produces a cut in the array. The feed force of the working body is provided by moving the chassis of the stone-cutting machine. 2 Il. sl C

Description

The invention relates to equipment for the extraction of blocks of natural stone.

A known underground stone-cutting machine for cutting and removing blocks, including a drive, a slab, guides, a column with a slider installed on it with a cutting head in the form of a face milling tool and a rear cutter with suction of sawmill waste. lifting points and lifting jacks.

A disadvantage of the known machine is the complexity of the design.

Also known is a cable-cutting machine, which includes a chassis with a drive for moving it, a working member in the form of a length of saw rope, guide pulleys for the saw rope located on the running gear and a drive of the drive member with a motor.

The disadvantages of this machine are the interaction of the saw rope with the drive pulley, which leads to wear of both the pulley and the saw rope, as well as the high consumption of free abrasive and water due to their cutting out of the kerf.

The purpose of the invention is to reduce the cost of block mining operations by reducing the consumption of free abrasive and water.

while improving the reliability of the machine.

The goal is achieved by the fact that in a stone-cutting machine containing a chassis with a drive for moving it, the working body is in the form of a cut of the saw rope, the guide pulleys for the saw rope are located on the running gear, and the drive of the working member with movement is driven with the possibility of rotation of the shaft and flywheels coaxially fixed to the ends of the shaft, while the ends of the cut of the saw rope are fixed on the outer end surface of the corresponding flywheel and are diametrically opposite the same distance from the longitudinal axis of the shaft, the shaft being kinematically connected with the engine.

FIG. 1 shows the proposed rope-stone-cutting machine, side view; in fig. 2 - the same, top view.

A cable-cutting machine consists of a trolley 1 with a drive 2, on which a drive 3 is installed, a drive shaft 4 with flywheels 5 at the ends, a fastener 6 for the saw rope 7, guide pulleys 8, a control console 9. In addition, in FIG. 1 and 2 shows the cuts 10 in the array 11 and the cut blocks 12,

Kanatna stone carving machine works as follows.

After cutting vertical cuts, for example, machine KNKM-1 in the cuts 10, the sawn line 7 is put into operation. After that,

they drive the cable saw drive and trolley travel. A saw rope 7 fixed to the flywheels 5, reciprocating through the guide pulleys 8, saws a stone in the horizontal plane.

The use of the proposed invention will allow the sawing of rocks in an inclined mine working, reduces wear of the saw rope and pulley of a stone-cutting machine, and also reduces the consumption of free abrasive and water.

Formula of iso-reteni

Stone cutting machine, including a chassis with a drive for its movement, a working body in the form of a segment of the saw rope, guiding pulleys for the saw rope located on the chassis

and a drive of a working body with an engine, about the fact that, in order to reduce the cost of work on the extraction of blocks by reducing the consumption of free abrasive and water while increasing the reliability of its work, the drive of the working body is made in the form of shaft installed with the possibility of rotation and coaxially mounted on the ends of the shaft flywheels, while the ends of the segment of the saw rope are fixed on the outer end surface of the corresponding flywheel and are located diametrically opposite to the same distance from the longitudinal th axis of the shaft, with the shaft kinematically

associated with the engine.
