Description

one

The invention relates to the field of extraction of i blocks of block stone.

i Known stone-cutting machines with thermal burners for cutting out granite blocks, consisting of a rail carriage frame, racks, traverses with three thermal burners attached to it, a reciprocating mechanism and a device for adjusting the position of a thermal tool on the vertical; However, the use of such machines is very limited, since most of the rocks, including granites, are weakly destroyed by the high-temperature gas jet.

In order to eliminate the noted deficiency and improve the process of cutting out blocks from an array, a stone-cutting machine is offered, on the traverse of which between thermal burners on the same line with them there are installed drill heads & for example, a punch type, and the device for moving the crosshead is made in the form of supporting and power cylinders with pistons, each of which

I is attached at one end to the top of the pillars, and at the other end to the traverse, with a reversing drive with an external gear gear mounted on the cross-cutting machine,

and on the track set regulatory stops. An air collector is installed in the proposed stone cutting machine to ensure constant parameters of the working mixture.

FIG. 1 shows a stone-cutting machine, a general view; in fig. 2 - also, side view; in fig. 3 - control circuit of pneumatic cylinders.

Stone cutting machine consists of a carriage 1 of frame structure, two racks 2, movable crosshead 3 with thermal burners 4 fixed on it and drill heads 5 with drills 6, clamps 7, two supporting 8 and two power 9 cylinders with pistons 1O and 11 and stationary beams 12, rigidly fastening the clamps 7. The carriage 1 is mounted on the track 13 moves between the adjusting stops 14. The movement of the carriage

reciprocating and provided by automatic switching / reversing drive 15, consisting of an electric device, a gearbox and a chain transmission, which causes the gear 16, which is in engagement with the rack rail 17 rigidly parallel to the track, to rotate. 18 and the control panel 19. The burners 4 mounted on the stone-cutting machine are not different in design from the benzone-air burners. However, other types of burners can be used (kerosene-oxygen, oxygen, and d.). Holes 5 use perforators, hammers or similar devices. Moreover, the number of drill heads should be less than the number of go, reels. The control circuit of cylinders 8 and 9 includes pressure gauges 2O, pressure control 21 and control valves 22. A safety valve 23 is included in the control system of the cylinders 8, providing a constant pressure on the piston of the cylinder 8, supporting only a movable one; traverse 3. Last Heo6xpflHMp iyifl; n 4J working conditions: brown heads, especially in case of fracture of fractured and non-native rocks. The work of a stone-cutting machine is carried out as follows. In a quarry, at the mining site, the rail track on which the stone-cutting machine is installed is mounted, connected to the power grid, pneumatic network and to the gas pipeline. At the same time, the track must be set so that the working tool of the machine (thermal burners and drill heads) move along the intended cut line. all tools to the upper starting position. In this position, in the drilling head 5, the drills 6 with crowns are set / sewed and the burner 4 is ignited. When work 1X) the reel is brought out 1 and 4 mode, the valve 22 of cylinder 9 opens. the drill bits 6 into the rock along the cutting line, after which the drill heads 4 and the drive 15 are put into operation. Then the machine, moving along the cut line, will act on the rock by thermal heating and mechanical cleavage, as a result rock layer. The reciprocating movement of the machine will provide o6jga3OBaHH e slots needed .. depths In a similar way, slots along the cut line can be obtained from all sides of the detachable block, after which the block is removed from the bottom. The natural fractures of the massif should be taken into account when choosing the direction of cuts. The subject matter of the invention 1 is a stone-cutting machine comprising a carriage, a frame, a reciprocating mechanism along a track, a post, a traverse with thermal burners, an actuator and a device for shifting the cross bar, which even cutting contours and expansion of the field of application, the stone-cutting machine is made with drill heads, for example, perforator ones, mounted on the traverse between the thermal burners, and the device for moving the traverse is on a support and power tsilindoov with pistons, each of which one end flax prikrep to the upper rack, and another - to the cross member. 2. The cutting machine according to claim 1, that is, that the drive is turned out to be eversive with the external gear six, and the track is made with adjustable stops. 3. A stone cutting machine according to claim 1, such that, in order to ensure the constant parameters of the working mixture, an air collector is installed on it.
