Abstract

Use: driving of horizontal workings. SUMMARY OF THE INVENTION: The front boom is provided with interconnected by means of gears with conical chisel cutters. The cutters are located in a vertical plane parallel to the axis of the boom. The distance between the axes of the mills is equal to twice the diameter of the mills. The frame is provided with mounted on its guides with the ability to move the portal support element. The supporting element is designed as a hinged parallelogram with folding means and platforms for placing concrete-water and drilling rigs on them. 5 il.

Description

The invention relates to construction and mining, and is intended to intensify the processes of penetration of horizontal mine workings in rocks of medium strength with the provision of their fastening by sucker rod and concrete reinforcement.

Tunneling machines for these purposes are known, for example, combine 4PP-2M of the Yasinovatsky Machine Works 1,

The lack of a combine - limited opportunities for the destruction of hard rock and relatively low productivity.

The closest in technical essence (prototype) is a combine for driving horizontal workings 2.

The combine includes a running gear, a feeder, a conveyor with a loading and unloading device, a rotary turret with a telescopic boom and a cutting rock-destroying body, and also guides on the frame of the combine with back boom mounted on them with a rock-destroying organ in the form of a screw with its own drive .

The disadvantage of the prototype is the limited capacity for the destruction of strong layers of rocks and relatively low productivity. The aim of the invention is the expansion of operational capabilities due to the intensification of the processes of penetration, the expansion of the zone of destruction and the range of rock strength.

The goal is achieved by a technical solution, in which the front boom is equipped with conical cutter mills, which are interconnected by means of gears, located in a vertical plane parallel to the boom axis, the distance between the axes of which is equal to

the military diameter of the mills, and the frame — mounted on its guides, with the possibility of moving the portal support element in the form of a hinged parallelogram with folding means and platforms for accommodating them to the concrete pipe and drilling machines.

The novelty of the claimed combine is the equipment of the front boom interconnected by means of gears with cone cutters located in a vertical plane parallel to the axis of the boom, the distance between which is equal to twice the diameter of the cutters, as well as the equipment of the guides of the combine frame with hinged folding betonovod and drilling machines. These same signs are significant, because achieve the objectives of the invention. Installing an additional swiveling rear boom with a hammer allows you to expand the range of the strength of the rocks being destroyed.

Figures 1, 2 and 3 depict a combine; FIGS. 4 and 5 show possible damage patterns of a slaughter.

The advantages of the proposed combine are:

- expansion of technological capabilities by equipping the rear boom with a drummer, and the front one - with several conical cutters connected with each other with gears, which expand the area of the downhole;

-expansion of the range of the fortress of destroyed rocks;

-the ability to perform, in the process of sinking, work on the sprinkling of the concrete and the installation of the rod support;

- significant economic efficiency.

Arranged the proposed combine as follows.

On a self-propelled chassis 1 with outriggers 2, a frame 3 with a feeder 4 and conveyors 5 and 6 is placed, a turning turret 7 on which the front telescopic boom 9c is fixed by a drive 10 with a central head 11, and additional heads 12 and 13, as well as tapered cutters 14-16, the axes of which are parallel to the axis of the boom. Additional heads are attached to the central head by means of mounting flanges 17 and provided with a gear 18 for imparting rotation to the shafts 19. Hydrocylin is provided for turning together with the turret boom ry 10. The support 21 is placed, which is reinforced in the rear upper portion of the frame

a breaking arrow 22 with drives 23 and 24 of its lifting and breaking.

At the front end of the rear boom 25 is mounted a holder 26 with a reinforced

there is a hydraulic hammer 27 with a rock-breaking chisel 28. Hydraulic cylinders 29 and 30 are provided for turning the hydraulic hammer. For turning the boom 22 away from the axis of the combine, a turning circle is provided

0 31 with hydraulic cylinder 32 turns. The carriage circle 31 is placed on the longitudinal guides 33 in the upper part of the frame 3. On the guides 33 with the aid of rollers 34 by means of paired articulated parallelolelograms 35 with braces 36, the scaffold 37 is strengthened. The layer of concrete sprinkles on the working arch is indicated by pos.38, the anchor fastening is posed .39, drilling equipment for drilling holes under anchor bolt 0 pos.40. The contours of the passable development are indicated by pos. 41 (see Fig. 4), traces of the introduction of taper mills are indicated by 42, and the inclined movement path of the set of mills is pos. 43 (see Fig. 5) horizontal

The 5 slots left by the cutters on the bottom are designated pos.44, the pillars between the slots are pos.45, the slots left by the cutters when turning the boom are denoted pos.46. The heading machine works as follows.

Using a self-propelled chassis 1, the combine is fed into the bottom of the passable output and the outriggers 2 are installed. Then, using the hydraulic cylinders 8 and 20, the boom 9 is set to the position required for operation and all the cutters are driven into the bottom (position 42), after which moving the boom to the side, made slots 43 and 44 with pillars 45 between them,

0 which, if necessary, can be destroyed by the hammer 27. With a chisel 28 on the rear boom 22. When moving the front boom along an inclined trajectory, the thickness is changed

5 formed pillars and when moving the boom at an angle of 45 ° you can get a smooth face, because pillars will be cut with cutters, because the distance between the axes of adjacent mills is equal to twice their diameter.

0 At a meeting of strong interlayers of the rock, as well as for processing the top of the bottom, a rear boom with a hammer 27 equipped with a chisel 28 is put into operation, moving the boom to the desired bottom point.

5 If it is necessary to perform concrete sprinkling and installation of roof bolting, they are carried out from the scaffolding 37, which on their rollers 34 can be moved to the face zone. Drill rigs 40 are provided for drilling holes in anchor bolts. The broken rock is loaded with feeder 4 to conveyors 5 and 6 and further to vehicles (not shown).
