Description

I,.

The invention relates to the mining industry, and mvjeHHO, to the tunneling machines with planetary executive bodies.

The planetary executive body of the sinking combine is known, including the carrier with the rays and the daskamn and the turning mechanism 13.

The disadvantage of such executive bodies is the lack of reliability and the high energy intensity of the process.

The closest solution in terms of the technical essence and the achieved result is a planetary test unit of the tunnel machine, including a disk drive, a turntable with a rack-and-pinion mehaviam with hydraulic jacks 12. The disadvantage of this planetary executive body is God’s energy intensity of the cylinder.

The inventive chain is to reduce the energy intensity of the destruction process.

The goal is achieved by the fact that the platform and included are equipped with interacting with each other, respectively, horizontal and vertical bevel gears.

On ф G. 1 - planetary executive body, side view; on r. 2 - the same, vkd from above in fig. 3 - the same, front view; in fig. 4 shows the disengagement grid of the executive cftraacMi in FIG. 5 section A-A / g. 1.

The executive consists of drove 1, beams 2 and 3 with a 4-bed bottom; Chambers 4 and 5, engines 6 and 7 which are rotated by rotation. Shski is equipped with tools 8 and blades 9 that reject broken coal on the augers of the loading body. The carrier is driven from the hydraulic jacks, the rods 1O and 11 of which are hinged to the frame 12

0, and the cylinders 13 and 14 are fed into each other in opposite directions along dovetail-type guides.

The spindles have toothed racks 15 and 1 b, each with sectors T1 and 18 of platform 19, on the turn shaft of which a bevel gear 20 is installed, transmitting torque to the carrier through gear 21. On the turn shaft of the platform there is also a sector 22 with cams 23 and 24, Impact operation on the tilting boat 25.

The executive body of the tunneling machine works as follows.

Disks 4 and 5, continuously rotating around their axes, have also forward movement. account of the rotation of the carrier 1. Thus, the incisors mounted on the disks 4 and 5 make a planetary movement. After the driver reaches one of the extreme positions, the gold shk of the hydrofilter 25 is shifted by the cam of the rotary sector 22, thereby changing the direction of movement of the cylinders of the hydraulic jacks and drove 1 to the opposite of the original one. With the approach drove 1 to another extreme position. The relocation of the rotary pistol 25 and the change in the direction of movement of the cylinders of the hydraulic jacks and the rotation of the carrier takes place again. Then the work of the executive organ is repeated in the described system.

The executive body provides the most efficient of all known coal or rock cutting schemes - by crossing cuts. Cross cutting allows to reduce the specific energy consumption for the destruction of the face. Processing by the specified organ can be performed both with continuous feeding of the combine to the bottom, and with periodic feeding of the combine to the extreme positions of the carrier.
