FIELD: mining. ^ SUBSTANCE: device for supply of flexible communications to working members of drilling machine includes flexible communications installed in the limit stop so that flexible communications of rotary head are located mirror-like in relation to flexible communications of the feed and are connected to rotary head and to the feed from one point. At that, flexible communications of rotary head are located in upper half of the device, and flexible communications of the feed are located in lower part of the device with possibility of their being folded and unfolded spirally at various speed, i.e. flexible communications of the feed are folded in folding area of flexible communications of rotary head. This decision allowed increasing the working travel of rotary head relative to working travel of the feed by two times without increasing the sizes of flexible communications. Limit stop directs folding-unfolding process of flexible communications strictly in one direction by means of its frame. At that, flexible communications of rotary head have the length which is not less than 1.5 of the frame length of drilling machine, and flexible communications of the feed have the length which is not less than 0.75 of the frame length of drilling machine. ^ EFFECT: possible transfer of optimum amount of energy carrier in order to ensure the required traction force to rotary head and feed, decreasing the dimensions of this device. ^ 2 cl, 3 dwg |
