DEVICE FOR TRENCHLESS INSTALLATION OF UTILITIES Russian patent published in 2011 - IPC E21B7/26 E02F5/18 

FIELD: construction.

SUBSTANCE: device comprises a base, a guide hingedly connected with the base, which is installed with the possibility of rotation in the vertical plane and fixation in intermediate positions, a mechanism of guide rotation, a carriage with the possibility of its displacement along the guide, a spinner for driving a roller shaft by means of a set of driving rods, a mechanism to move a carriage and comprising a planetary gear, comprising a master gear, a carrier, a set of satellites mounted in the carrier, and a central wheel engaged with the master wheel by means of satellites, at the same time the torque is taken off via driving rods to the roller shaft either from the master gear or from the carrier, besides, the mechanism to move the carriage is arranged in the form of a chain gear in accordance with the circuit of the carriage travel doubling, at the same time the device is additionally equipped with the mechanism of the guide rotation in the horizontal plane arranged as a flange joint, and the mechanism to rotate the guide in the vertical plane is arranged as a screw-nut. The master gear of the planetary reducer of the spinner is arranged as hollow and is mounted on a hollow driving shaft, the drive of which is carried out from the hollow gear, installed on the hollow shaft with its drive from the gear drive. Driving rods to the roller are pulled through the hollow shaft and are connected with the mechanism of torque transmission at the roller shaft by means of a flange installed on the driving hollow shaft or on the carrier of the planetary reducer.

EFFECT: expansion of the field of application of the proposed device in city constrained conditions, reduced labour intensity and cost of works.
