The invention relates to the drilling technique, namely the mobile drilling agreg the water, maintenance (oil, gas).

Mobile units, lifts and installations are driven by internal combustion engine - diesel or gasoline and are divided into two groups on the drive.

The first group of units is the drive mechanisms for drilling and perform round-trip works only from a running internal combustion engine of the vehicle chassis on which the unit is mounted. This unit universal-drive can't be, because it has a single motor drive systems, installation and car, and if it stop, stop all the mechanisms.

The second group of units is driven more by the internal combustion engine mounted on a common platform mechanisms of the drilling rig. This engine operates independently of the driving of the internal combustion engine of the vehicle chassis and is the only drive of the drilling rig. This unit universal-drive is not considered, because when you stop the main engine engine chassis cannot operate the drilling rig, because the kinematic scheme of the unit is not turned on.

The units driven by the internal combustion engine of the vehicle chassis Il is e failure of a single drive-internal combustion engine stops all installation and maintenance of all works. Often stop leads to complex emergencies and large financial costs.

Known mobile drilling installation comprising a base chassis with power unit and transmission, the drilling mast with rod carrying a drilling tool mounted on the mast block, hook suspension and winch with rope (see and.with. The USSR 160482, IPC E 21 In 7/02, 1963).

A disadvantage of the known device is the complexity of construction hoist, due to the separate part of the rope.

The closest in technical essence and the achieved result of the claimed unit is a mobile repair the drilling rig, which includes a self-propelled vehicle base, for example a truck, on a platform which is mounted pole with a pulley system, drawworks, mechanical main drive mechanisms, hydraulic drive auxiliary, front and rear hydraulic outriggers.

A characteristic feature of the unit is that it is supplied mounted on a transport base additional adjustment platform mounted on the rear outriggers (see RF patent 2162133, IPC E 21 In 7/02, bull. 2, 2001).

Defects in the Assembly of the prototype is the lack of universitara allowed to operate the unit in the presence of a source of electricity (mobile diesel-generator power plant or industrial grid).

The problem is solved by the characteristics specified in the claims, in common with the prototype, such as mobile repair the drilling rig, including a self-propelled vehicle base, for example a truck, on a platform which is mounted rig with a drilling system, drawworks, mechanical drive of mechanisms, which include the rotor and drawworks, hydraulic auxiliary drive mechanisms and hydraulic outriggers, and distinctive essential features, such as the basic mechanisms of cell repair of the drilling rig is made with the possibility of a drive from the engine of a self-propelled vehicle base, which is kinematically through the transfer case, the box changes gear and cardan transmission associated with the transfer gear basic mechanisms and equivalent from a reversible direct current motor mounted on the platform in front of the rig winch, which is kinematically connected with the transfer drive gear drawworks and rotor.

The combination of characteristics of both known and new allows you to create universal-drive mobile repair the drilling rig. The above distinctive prisni. The use of the proposed combination of essential distinctive features in the prior art was not found, therefore the proposed solution meets the patentability criteria of "novelty". One set of new essential features with common, well-known provides a solution to the problem is obvious to experts in the field of technology and demonstrates compliance of the claimed technical solution to the patentability criterion of "inventive step".

The present invention is specifically illustrated by the following examples of the invention, which illustrate but do not limit the scope of use of the invention.

The invention is illustrated by the following drawings.

In Fig. 1 shows a General view of the unit of Fig.2 is a kinematic diagram of the unit.

Mobile repair the drilling rig includes a self-propelled vehicle base 1 (Fig. 1), such as a truck chassis BAZ-69096 or vehicles were modernized. On the platform 2 of the transport base 1 is mounted rig with 3 pulley system 4, drawworks 5, the mechanical actuator 6 of the basic mechanisms of the unit (winch, rotor, and other), the hydraulic actuator 7 auxiliary fur is revnum the direct current motor 9, mounted on the platform 2 in front of the drill winch 5. The engine 9 is kinematically associated with the transfer gear 10 drive drawworks 5 and rotor (Fig.2).

Self-propelled vehicle base 1 includes a motor 11 (YAMZ 8424.10 power 450 HP) gearbox 12, through which the shaft 13 is connected with the transmission power take-off 14. PTO 14 through the intermediate shaft 15 is connected to the gearbox with transfer case 16 drive pumps, through the shaft 17 with gear handout 10 drive drawworks 5 and the rotor 18. Gearbox transfer case 10 via the output shaft 19, sprocket, Z=31, Z=18, chain drive 20 is connected with the lifting shaft 21 of the winch 5. Output shaft transfer gear 10 through the clutch 22 and the drive shaft 23 through an angular gear 24 is connected with the rotor 18 universal-drive.

The direct current motor 9 type P2-450-48 LULZ (500 kW) through the coupling 24, the sprocket Z=15, Z=30 and chain drive 25 emergency actuator 26 is connected to the gearbox with transfer case 10 of the drive drawworks 5 and the rotor 18. The shaft 21 of the winch 5 is a brake 27 auxiliary hydraulic. The shafts 23 are intermediate support 28. Hoist towers 3 contains tartally drum 29.

Mobile repair drilling rig operates as follows: the power station, and it is through the pneumatic coupler 24 and chain drive 25 with a sprocket Z=30, Z=15 transmits rotation and the necessary power to the gearbox transfer case 10. Gearbox transfer case 10 through the output shafts 19 and driveline transmits rotation and torque on the sprocket Z=15 and Z=18, from these stars power chain transmission is transmitted to the lifting shaft 21 winch 5 plants for the production of the necessary tripping and maintaining the drill string in weight. From transfer gearbox 10 via the coupling 22 cardan transmission 23 power into gear corner 24 which through the drive transmission 23 actuates the rotor 18 of the drilling rig. All mechanisms, the actuator described above, the direct current motor 9 equivalent can operate from a diesel engine 11 of the drive chassis 1. The engine 11 through the transfer case 12 and the box changes gear 14 through the drive transmission 15 actuates a gear transfer case 10, which may be tantamount to operate from direct current motor 9. Further, the transmission of power from the diesel engine 11 is performed according to the scheme described above in the case of the drive of the drilling rig from electr the Gata. The unit became universal-drive because the kinematic diagram of the diesel engine introduced reversible DC motor with braking and adjustable from zero to nominal speed. The motor included in the scheme, diesel drive unit actuates all the mechanisms of the machine, operates independently of the propelling motor of the vehicle chassis and is powered by the energy produced by the diesel generator mobile power plant or a commercial power supply, located a short distance from the drilling and repair work. The versatility of electro-diesel drive installation is that in the event of a power outage, failure of the drive motor included in the kinematic scheme of a universal-drive actuator, immediately starts up the engine of the vehicle chassis and performs all the functions of the direct current motor. Stop drilling or development does not occur. Accidents and costs because of the drive are excluded.

Universal-drive mobile unit has a number of advantages over commercially available units with motor inside the I DC if necessary, you can perform all kinds of work at the minimum speed of the motor, this will substantially secure the execution of complex of works on liquidation of accidents in drilling and complications wells, because the speed of the direct current motor can be adjusted from zero to maximum. The internal combustion engine is permitted to operate at 500-1200 rpm, and from 0 to 500 rpm in General cannot work.

The second advantage is that the unit is much easier to maintain and operate under severe low temperature conditions of Siberia and the Arctic, because the motor does not require pre-heating and maintain the required temperature during operation, which is necessary for the internal combustion engine.

The third advantage is that the unit when working on the drive from the electric motor does not require fueling diesel fuel or gasoline, and in a polar - only Arctic fuel and costly lubricants, different in winter and summer maintenance.

The fourth and one of the major advantages is the ecological purity universal-drive mobile unit during operation of the motor. No zamazuchennoy site and the contamination of the atmosphere with exhaust gases yle="text-align:center; margin-top:2mm;">Claims
