Known birotational tunneling shield unit /GeoHot/ (application No. 2009129575/03 /041190/ from 31.07.2009, Authors: leliuh B.F., Aksenov V., efremenkov A.B.). It is composed of three sections, arranged one after the other. Two front sections, starting from the bottom, mounted on the diaphragm by means of ball chasing. Ball shoulder straps made integral with a toothed crowns bevel gear. The diaphragm is mounted a rotational drive partitions. Crowns ball straps are in engagement with diametrically opposite sides with a leading bevel gears drives the rotation of the sections located on the diaphragm. Aperture with sections mounted on the front end of the beam. Beam its rear end mounted in the guide rails of the rear section, preventing its rotation, but permitting its movement along the axis of the rear section. The beam has an actuator associated with the rotational drive partitions. Beam is simultaneously the tray, which is transporting auger with drive.

On the outer surfaces of the front rotating sections of the spiral blades with a counter direction of winding. Before the screw blades and the elements mounted counter-rotating small Executive bodies with the drives.

On the front side of the diaphragm is mounted a hollow beam. On the front (face) of the end of the hollow beams náchod the tsya socket and loading the rotor blades. At the bottom of the cone rotor has openings G, located against sleeve small Executive bodies. The rotor is mounted on the beam in front of the socket and provided with a drive connected with the main Executive body. This actuator is connected with the frontal cone, which is part of the main Executive body.

The disadvantage of this birotational tunneling panel of the unit is a significant relief zakomornogo layer massif, rugged channels under the helical blade and the elements of counter-rotating, which reduces the resistance zakomornogo layer shear. It may result in jamming of the unit at the bottom and the development of an emergency.

This birotational tunneling shield unit is a prototype and similar.

The objective of the invention is the increased resistance zakomornogo layer of the mountain massif on the shift by reducing its notched channels.

This task is achieved by the parallel spacing of the axes of rotation of the two front sections at the distance of 50-100 mm higher than their overall diameter (figure 1). Thus, the front section are not one behind the other and next to each other. Hence the name - duplex. In this case, anywhere zakomornogo layer massif (perimeter) of manufacture will be cut channels only od the second section. In a longitudinal channels for elements of counter-rotating (as in themselves the elements of counter-rotating) no need, as the rear section and the entire tunnel will have an oval cross-section, the overlapping section of the two round front sections. This out-of-roundness and will prevent rotation. The front section is mounted on the supporting beams through ball straps on the diaphragms with the rotational drive of the sections in opposite directions. Ball shoulder straps made integral with a toothed crowns bevel gear. Rotation of synchronized sections. The beams of their rear ends are mounted in the guide rails of the rear section, preventing their rotation, but permitting their movement along the axis of the rear section. The beams have the drive associated with the rotational drive partitions. Each carrier beam is simultaneously the tray, which is transporting auger with drive.

On the front ends of the diaphragms are mounted hollow beams. On the front (face) of the end of the hollow beams are sockets and loading the rotor blades. On the conical bottom of each rotor has openings G, located against sleeve small Executive bodies. The rotor is mounted on a hollow beam in front of the socket and provided with a drive connected with the main Executive body. This drive is outinen with the frontal cone, which is part of the main Executive body. The main Executive bodies of drum mounted for rotation around its axis and around the axis of the section (figure 3).

On the rear section of the top and bottom (horizontal) and (vertical) is also mounted on the Executive bodies. They are geometrically complementary to the cross section of two circular tunnels to the oval. Mountain mass, separated by the Executive bodies of the front sections, augers on trays and hollow bearing beams is served in the rear section, where the scraper conveyor is connected with a mass of rock, separated by the Executive bodies of the rear section, in one thread and tray auger with drive, is derived from it.

On the outer surfaces of the front rotating sections of the spiral blades, with the eastbound direction of winding. In front of helical blades mounted small Executive bodies with the drives. Description duplex geocode illustrated by drawings:

figure 5 shows a section b-b In figure 1 duplex geocode.

Duplex GeoHot consists of three sections: two front sections 1 and 2 (figure 1)mounted on the supporting beams 3 and 4, with the possibility of rotation of the sections 1 and 2 in opposite directions by means of the rotational drive and the extension 5 and 6 (figure 2), and one of the rear section 7, on which the guides are mounted beams 3 and 4 with the possibility of longitudinal movement. On the outer surfaces of the front sections 1 and 2 rigidly fixed helical blades 8 and 9 with the opposite direction of winding, consistent with the direction of rotation of the front sections 1 and 2. Before each blade is mounted a small Executive body 10 with the actuator 11 and the screw 12 (Fig 1, 2). The front section 1 and 2 are mounted on the supporting beams 3 and 4 through the aperture 13 to the ball shoulder straps 14. In the center of the diaphragms 13 are mounted hollow beam 15 (2; 3), inside which is placed screws 16 to the actuators 17 and in the supporting beams 3 and 4 of the rear section 7 - screws 18 to the actuators 19 (Fig. 2, 4).

On the front (face) of the end beams 15 are mounted in the sockets 20 and loading the rotor 21 with blades 22 (figure 3). The rotor 21 is connected to the rotational drive 23, mounted on a hollow beams 15 in front of the sockets 20. The actuators 23 are connected with the main Executive bodies 24 and 25, with the possibility of rotation around the axis of the beam 15 (magic cube MOV is e-filing) and around its own axis (cutting motion). These actuators are connected with nose cones 26 relating to the chief Executive bodies 24 and 25. In the rear section 7 is mounted screw 27, which is connected with a gear 28 on the sleeve 29.

On the frontal surface of the rear section 7 at the top and bottom horizontally and center vertically are the Executive bodies of the rear section 30, 31, 32 (figure 5). Between the Executive bodies 30, 31, 32 of the rear section and the screw 27 is mounted scraper conveyor 33.

Duplex GeoHot works as follows.

All work duplex geocode technologically divided into three operations that must first be done in a certain order, following this description, and further in accordance with the necessity.

First operation: full duplex GeoHot Assembly or agregate delivered on a prepared pad mounted (going) and is installed close to the breast of the face. The beams 3 and 4 must be drawn into the rear section 7. Included drives 23 chief Executive bodies 24, 25, with a frontal cone 26, small Executive bodies 10 of the front sections 1 and 2 with transporting augers 12 (within sections 1 and 2), 16 (hollow beams 15), 18 (in the supporting beams 3 and 4) and 27 (in the rear section 7), and scraper conveyor 33. Included drives 5 and 6, rotation and extension of the front sections 1 and 2, synchronized with vydvigaemsya beams 3 and 4. Synchronization is necessary for cutting in a mountain array of channels with a pitch of the helical surface is equal to the step of winding of the spiral blades 8 and 9. The first operation ends when the front section 1 and 2 will cut about a quarter turn.

Mountain mass, separated by the Executive bodies 10, 24, 25 and 26 of the front sections 1 and 2, falls down, which is chosen by the blades 22 of the rotating loading of the rotor 21, is lifted them up until the pitch angle of the blades 22 will exceed the friction angle of the rock mass of the material of the blades. Then she slips into the socket 20 and augers 16, 18, 27 and scraper conveyor 33 is removed from the duplex geocode.

The second operation consists of the elevation of the rear section 7 to the front sections 1 and 2 until it touches the chest slaughter Executive bodies 30, 31, 32 of the rear section 7. When this synchronization is disabled, the front section 1 and 2 stop. Work drives rotation and extension 5 and 6 only pulling up the rear section 7 to the front sections 1 and 2. The drives are small, chief Executive and Executive bodies of the rear section off, drives off all of the screws and scraper conveyor.

The third operation is the standard operation mode. All Executive bodies: 10, 24, 25, 26, 30, 31 and 32, augers: 12, 16, 18, 27 and scraper conveyor 33, actuators: 5, 6, 11, 17, 19, 23 and 28, synchronously rotate the front behold the tion 1 and 2.

The rock mass is removed from the duplex geocode the same way as in the first operation.

Technical result: duplex GeoHot allows you to get in the mountain massif oval tunnel, convenient for the many needs in engineering and urban planning.

On sukantara layer cut only one spiral groove and only half of the circumference and a longitudinal groove, for elements of counter-rotating, non-existent, as there are no elements of counter-rotating. In addition, if specified in figure 1 the direction of rotation of the sections of the friction force on the outer surfaces of sections 1 and 2 cause the components, upward, which reduces the friction force from the weight of the sections. In the opposite direction of rotation of the front sections 1 and 2 with the axes of the main Executive bodies significantly reduced structural loads due to the subtraction of torque, which will allow it to reduce its weight and cost of power.

Duplex GeoHot, consisting of three sections: two front, starting from the bottom, mounted on support beams with the actuator by means of ball chasing serrated crowns bevel gear which engages with the leading bevel gears drives the rotation of the sections located on the diaphragms, which are mounted on the front ends of the supporting beams to the actuators, and each carrier b is the left main coronary artery with actuator mounted in the guide rails of the rear section, with the possibility of extension, and inside the carrier beams mounted auger, with a separate drive, the outer surfaces of the front rotating sections are helical blade with a counter direction of winding; and before each blade mounted small Executive authorities with an individual actuators and sleeves with screws, and in the center of the diaphragms are mounted hollow beam, in which are mounted screws with actuators, with the front - face end of the hollow beams, mounted sockets and loading the rotors with the drives connected to the main Executive bodies of the front sections and the actuators and the Executive bodies of the rear section are located on its front wall outside: top and below is horizontally and center vertically, with scraper conveyor, tray and screw with the drive located behind the front wall of the inside of the rear section.
