Drive self-propelled drilling rig located on the back of a mud pump (not pevka h, the ramp rises on the ready rack 29.Undercarriage is self-propelled drilling rig operates on the principle of the rolling roller 5 on rolling beam 4 (Fig. 4,5,6). Perform the movement of the power cylinders 7, 8 are placed on the four block-modules hydrobiidae, arranged in parallel in the longitudinal ribs of the platform 1. The rods of the power cylinders 7, 8 are connected with the rolling beams 4. Block-modules hydrobiidae move in pairs - two outer and two medium. In Fig. 5 and 6 show the initial position before driving. When the support plate 10 on the ground does not rely on (Fig. 5), the hydraulic cylinders 7 is able to move only rolling beams 4 by 6 lifts. This cycle of movement is called preparation. The average block-modules 3 (Fig. 6) rely on the ground and when the reciprocating action of the operating cycle, movement mechanisms 8, respectively, move the platform to a distance equal to the length of their stems. The change in direction, turn the rotary device 11 under the influence of the power cylinder 9 and the lift 12 (Fig. 4,7). All 6 lifts go up, i.e., the average block-modules 3 and at block modules 2 does not rest on the ground. The platform is based on Soglasovanija job designing the installation. To overcome boggy paths must be provided on the support plates 10 pin spring 13 connected to the grid of the cable 14.The rotation of the rotor 15 perform through hinged to the platform four bilateral power cylinders 17, pivotally connected by a rod with gear flywheels 16 (Fig. 3) Lifting operations are performed upside-down hydraulic telescopic lifts 19 enshrined in glasses-the conductors 26. Lifts 19 are interconnected by a beam 27, which is fixed swivel 28 and the beam 18 (Fig. 1, 2). On the side of the hydraulic telescopic lift 19 fixed cantilever beam 20, which, through the turntable 23, fixed telescopic boom of hydrocrane 21, on the end where the automatic connector key drill pipe 22. In the area of automatic connector key drill pipe, on the Foundation 24, a candlestick 25. Moving drill pipe and drill stem between the candlestick 25 and the rig is running in automatic mode.The invention allows to reduce the cost of drilling, to mechanize the flow of drilling pipes and to increase productivity.
