The invention relates to the mining industry, and is intended for drilling of deep wells on the mainland and on the shelves. The invention consists in that the driving device, the installation is made of four block-modules hydrobiidae, arranged in parallel in the longitudinal ribs of the platform rotator is placed in the middle of one of the ribs, the rotor is constructed with hinged crown with the possibility of rotation by means of the four gear wheels, pivotally connected with two-way rods of the power cylinders, hinged to the platform, in the center of the platform above the rotor in glasses-conductors vertically installed made parallel and inverted telescopic hydraulic lifts are interconnected by a beam fixed on a swivel, on the side of the plane lift fixed cantilever beam, through which the turntable is fixed telescopic boom of hydrocrane, at the end of which is placed an automatic connector key drill pipe, in which is installed a candlestick. The invention allows to increase productivity and to provide increased procedimento for drilling deep wells on the mainland and on the shelves, namely, self-propelled drilling rigs.

The closest analogue in relation to the claimed invention is the patent of the USSR 1838565 A3, class E 21 In 7/02, 1993, according to which the self-propelled drilling rig includes a platform with the traction device and placed in the center of the platform, the rotor, the movement mechanism and the telescopic hydraulic lifts for the implementation of the tripping operation.

The disadvantage of the prototype are: unsafe method tripping operation performed by the winch, with the possible breakage of the cable; limited travel on the road.

The purpose of the invention to eliminate the above mentioned disadvantages, to reduce the cost of drilling, to mechanize the flow of drilling pipes, to increase productivity and to improve the patency of the installation.

This goal is achieved by the fact that self-propelled drilling rig, comprising a platform with the traction device and placed in the center of the platform, the rotor, the transfer mechanism, telescopic hydraulic lifts for the implementation of the tripping operation, while the undercarriage is made of four block-modules hydrobiidae, arranged in parallel in the longitudinal registi, on rolling beam fixed lifts with base plate, a transfer mechanism mounted between ribs and made in the form of a cylinder, and its piston rod is connected with the rolling beam, for changing the direction of travel, the installation has a rotary device that is placed in the middle of one of the ribs, the housing and rolling beam rotator is curved along the curve formed by the radius drawn from the center vertical axis of the lift, mounted on the side plane of the platform, to the rotary device, and the rotor is constructed with hinged crown with the possibility of rotation by means of the four gear wheels, pivotally connected with two-way rods of the power cylinders, hinged to the platform, in the center of the platform, above the rotor, in glasses-conductors vertically and parallel installed upside-down telescopic hydraulic lifts are interconnected by a beam fixed on a swivel, on the side plane of the telescopic hydraulic lift fixed cantilever beam, which, through the turntable, fixed telescopic boom of hydrocrane, at the end of which the size of the file posted on the block mud pump and includes a pump and a regulating unit, connected by pipeline with hydromechanically.

The invention is illustrated by drawings, in which: - Fig. 1 - type self-propelled drilling rig front - Fig. 2 - type self-propelled drilling rig side - Fig. 3 - type self-propelled drilling rig top - Fig. 4 - way device for self-propelled drilling rig, - Fig. 5 - section a-A (Fig. 1), - Fig. 6 - section b-B (Fig. 1), - Fig. 7 is a view of the rotator of self-propelled drilling rig side - Fig. 8 is a diagram increase the area of support for self-propelled drilling rig for the passage of the marshes tundra.

Self-propelled drilling rig includes a platform 1 with a driving device (Fig. 1) and placed in the center of the rotor 15 (Fig. 3), the transfer mechanism, telescopic hydraulic lifts 19 for the implementation of the tripping operation. Undercarriage is made of four block-modules hydrobiidae, arranged in parallel in the longitudinal ribs 2 and 3 (Fig. 4, 5, 6) of the platform 1, each of which contains a rolling beam 4 (Fig. 4, 5, 6) placed between the rollers 5. The ribs on rolling beam 4 is fixed lifts 6 with base plate 10. The transfer mechanism 7 and 8 secured between the ribs and made in the form of a cylinder, and its piston rod (Fig. 4, 7), which is placed at the middle of one of the ribs, the housing and rolling beam rotator 11 is curved along the curve formed by the radius drawn from the center vertical axis of the lift 12 with a support platform mounted on the side plane of the platform, to the rotary device, and the rotor 15 is articulated by the crown with the possibility of rotation by means of the four gear wheels 16 (Fig.3), pivotally connected with two-way rods of the power cylinders 17, hinged to the platform. In the center of the platform, above the rotor, in glasses-conductors 26 (Fig.1, 2) vertically mounted performed parallel and inverted telescopic hydraulic lifts 19 (Fig. 1, 2, 3) interconnected beam 27 (Fig.1) on which are fixed wedlug 28. On a side plane of a telescopic hydraulic lift fixed cantilever beam 20 (Fig.1, 2, 3), through which the turntable 23 mounted telescopic boom of hydrocrane 21, on the end where the automatic connector key drill pipe 22, which has a candle holder 25 (Fig. 3). 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.
