Machine heading "TATIANA" - a device designed to create the required mining types and sizes of machines for doing tunneling mates, capital and support, horizontal, ascending and descending cylindrical openings and arched section with a high rate of penetration 500-1000 RM/month.

In the eighties the average annual sinking shafts of the main and auxiliary openings in the USSR, actual and planned, was 50-70 p.m., the sinking of 150 m or more was considered high-speed penetration, for it turned out titles, orders, medals, securities (cars) gifts.

Conducting patent research, the author did not find any significant changes in the structures of tunneling devices and fundamentally new approaches to the management of tunnel works, so the average speed (planned) rose up to 70-100 m Plasma EN 2008121462, 2008116368, laser, fusion ("MOLE") penetrations in the future, mechanized same penetration not yet exhausted all its possibilities.

Now, in the age of mechanization and automation, offers many inventions to increase the rate of penetration, CJSC "Donetsk coal" Novocherkassk Polytechnic Institute proposes to increase the rate of penetration drilling and blasting method EN 2048715, design institutes offer at Uchenie swept roadheaders, such as CCP, RSCC, 4PPT-2, EN 94033685, even with two working bodies and measured including carriers EN 2039244, equipping tool on the desktop authority hydroshock mechanisms EN 2034986, 2004126848. For working driving large cross sections, we offer a shield large diameter installation swept harvesters at different levels of the shield EN 2011831.

DONGIPROUGLEMASH developed tunnel complex "SOYUZ-19". Russia becomes tunnel complexes U.S. firms "ROBBINS" and German company "HERRENKNECHT" (the world's largest machine for tunneling cyclic action). All these rotor, around the cylindrical section of the face, the complexes are very complex, bulky, bulky, power-consuming, difficult to manage, with great efforts of the head on the bottom and very expensive devices.

The modern idea is EN 2008116368, 2008121462 offering to produce the driving of using plasma melting designed to generate breed using melt to fill sabotoge space, casting poles, etc

Similar in approach to solving problems sinking mines is EN 2023153, Fig.2, with eccentric bushings for the design of the generation profile. Design 1, 2 are not able to keep the direction and stable contact of the rotor with the bottom breast due to ease of construction, d is I the example of the CCP and 4PPT - 2 Kopeysk plant, with hard contact of the working body with the bottom jump to bottom, as grasshoppers, lost direction and contact with the bottom, and 1 on the working body require a lot of effort to disassemble slaughter, and caterpillars device because of its ease will slide over the ground and tear of the belt fails, the control mechanism and drive caterpillars due to the lack of rigidity of the location of the harvester dynamics, complex kinematics of transmitting rotation from the motor to the carrier and rotors. There are many proposals devices: SU 99832, 123111, and others, but they all have certain disadvantages listed above.

The closest to solving the problems of penetration is SU 1694909 using a three-beam crawler, advanced kinematics of the working body, but has disadvantages; the planetary working body in two disk perpendicular to the axis of generation, large slip angles of the cones and the increase in energy costs, complex and costly system of special boot device boot Central auger destroyed the breed.

The present invention is directed to a compact, simple in construction, disassembly and Assembly, maintenance, reduced load on the working face, reliability and cost of the device.

The technical result consists in increasing the productivity of the device is Ista, the increase in the rate of sinking up to 500-1000 RM/month.

In the rotary working body across the cross-section generation is attended by all tools (cutters, milling cutter) and require increased effort on the face, great weight, good traction with the ground, roof, sidewalls and high-power propulsion complex on the face continuously or cyclically. The design of these working bodies provides for the slip angles of the cones from 3 to 12 degrees depending on the speed of rotation of the working rotor and drove, and it is already planned increased wear of the cones, bearings and, consequently, increasing energy consumption.

Installation of the working bodies of the rotors on the sleeves was taken at an angle significantly reduces the axial load. Imparting rotation to the lower cage and the rotor, the counter force destruction slaughter will try to move, to turn the harvester, but by connecting to the load the second (large) drove with his rotors, the opposing forces of the first led will be fully compensated and will only require efforts on the destruction of rocks by wave rotors. Because of the small rotors drove in the work involved 50% of the working tools, the burden on them will be 0-MAX-0, and the load value will be small. The large rotors drove participates 1/4 tsp bits, which is too small the load is. Weight, relatively small by design, machine and effort podemcrane blocks wheels enough to strictly consistent rotation with selsyns were taken with rotors that spin, are screwed into the bottom step of tilting the rotors to maintain the stability of the machine, to create efforts for its movement and to compensate for the load on the working face, it is sufficient to work on horizontal, descending and rising workings, even on vertical lines (trunks). Due to the hydraulically operated ball connection of the two housing parts has the ability to change the direction of the penetration up-down, right-left, to develop a pair workings of high velocity drilling, to make a u-turn machines on the pair in the shortest possible time.

The proposed device free from the above drawbacks and has a number of advantages, as he has taken all subsequent processes and is left:

1. Development of the breed.

2. Issuance of destroyed rocks from the bottom.

3. Protection of operating personnel from dripping rocks from the roof.

4. The design profile is set to sweep bemovie cutters.

The benefits.

1. The compact size.

2. The simplicity and ease of construction.

3. Maintainability, reliability. Simple and reliable kinematics of the interrelated parts and components.

4. Agility, the ability to work the s on the slopes and steeply dipping formations. To do u-turns on the pair in the shortest possible time.

5. Snap manipulators (drills, punches).

6. Low energy consumption.

7. A small value.

This technical result is achieved by the fact that the tunneling machine includes an Assembly housing 7 with ball hydraulically operated connection 6 assembled on the housing carrier 3 and 4 rotors 1 and 2 with hydraulic drives, chain conveyor, block 5 motor and tank wheels with hydraulic cylinders and jacks for installation of the machine along the axis of generation, to create a more rigid contact the front of the housing with the side surface generation, reduce vibration from the rotors, mobile blocks the front of the case are established tank rubber wheels on the rear of the chassis are mounted wheels with road tyres, inflated porous rubber (micropore under pressure for the tires. To ensure rigidity of the device (spontaneous slip on the slope, the repair of any unit of the wheels, conducting mates) each part of the body is equipped with 5 blocks of wheels, each with its drive through a worm gear, the thrust jacks are equipped with HPA - hydropneumatic batteries with automatic support a given pressure. To protect the staff, there are special is poddomkratit valve 10 of the roof.

To start the machine in operation assemble it in the open space in front of a specially designed input parameters required rough framing and the size of the machine, make the connection for all communications, produce test units and mechanisms, then the machine power feed is served in the log output. After the supply device to the chest of the face include a pumping station to supply hydraulic rotors 1, 2, led 3, 4, chain conveyor (the drawing is not specified), running blocks wheels 5 mounted on axes 9 at the point of intersection of the axis with the diameter profile of the cylinder 8, and slowly injected into the bottom breast working body, then include the machine in the required modes of operation. The working body at a constant, controlled selsyns filing screwed into the bottom, the design of the arched profile of the cross section by moving the outer rotors on directing a large drove on copier installed in front of a large planet carrier, figure 2 shows the angular position 2* outer rotors, the final design of the corners is bemovie cutters. Broken rock is removed the chain conveyor located at the bottom of the device between the bottom blocks of the wheels. Between the rows of blocks wheels in roof space overlaps poddomenami flaps overlap 10 to protect the service staff is tons of dripping rocks from the roof. The rear part of the housing required in the first place, to create rigidity to the lightweight construction, maintain good contact of the working body with a bottom, distribution of significant efforts by the filing of the face between the blocks of the wheels, preventing rotation of the wheels and increased wear. For the construction of mates have rigid coupling of the device with the ground and the roof, because during the construction of the pairing is the break in the axis of the housing to constructively laid maximum value at the point hydraulically operated ball joint 6, and one side will leave contact with the device to remain in contact will be soil - roof - 1 sidewall front portion of the chassis, and full contact of the second part and so on, than due to the installation of 5 units of wheels on each side of the hull, and, secondly, on the rear of the case possible location of the hardware of the device, as well as equipment for conducting attachment.

For the implementation of the reversal device is disassembled ball joint, and because each part has its own managed move, the rear part 7 of the first makes a turn and goes in pair, then the same procedure, the front part 7; produce hitch parts, connect the oil system running to the oil pump greater productivity, and the device its course is delivered in a new fence is.
