The technical field

The invention relates to the design of mobile drilling rigs used in the construction for drilling vertical and / or horizontal wells for various purposes.

Prior art

Mobile drilling rigs, providing drilling wells for various purposes widespread. Typically, this specialized installations for drilling, for example, vertical wells. For example, the Italian Apageo Segelm" produced relatively small machines "Apafor 22" and "Apafor 30" for drilling (see the prospectus of the company, Russia, 1997) under construction. Also known drilling rigs company ATLAS COPCO and many others, including installation, for U.S. patent No. 4068728 (UNITED STELL Cor.), 1978, However, these machines are highly specialized to perform other works are not intended, and used in a different capacity can not.

However, a small construction firm, with quantitatively limited fleet of construction equipment, interested in minimizing the Park production equipment and therefore the universality of the application of the individual vehicles of the Park.

On the other hand, is known for the multipurpose municipal construction machine, for example, type MKSM-800 (Kurgan plant), pumas-500, 600 and 1000 (which of elegantimoda), BOBCAT-500 and 600 firm "CLARK" (prspct firm, Brussels, 1983), machines GEHLMAX Champion" and others that can perform a whole range of construction works for which demand exists on any construction site.

In these machines the main (power) is the hydraulic running gear, functionally and structurally very close to the bulk hydraulic suspension rig for U.S. patent No. 4068728 (UNITED STELL Cor.), 1978, which allows the use of machines of this type as the base chassis for the drilling rig and to solve the task.

Thus as the closest analogue we offer drilling rig should take the rig for U.S. patent No. 4068728 (UNITED STELL Cor.), 1978

General and essential features of the proposed drilling rig and famous for U.S. patent No. 4068728 (UNITED STELL Cor.), 1978 are: basic chassis truck with a frame, propulsion stroke of the right and left sides, volume hydraulic drive with hydraulic motors drive the propellers, mounted on the frame of the undercarriage through suspension frame feeder with drive mechanisms rotating drill rod along the axis of the bore with hydraulic motors drives these mechanisms.

Disclosure of inventions

The aim of the invention is to create a structure of self is the first installation for drilling vertical and / or horizontal wells, the maximum possible power loading at the base of the undercarriage of universal application, which can be used in the production of other works in the construction site that may significantly increase equipment utilization and reduce the time of his return.

This hinged drilling equipment and the base machine must be structurally linked, and above all energy, schematic and layout capabilities, while providing security during operation of the machine.

Given that in the above-mentioned multi-purpose construction machines hydraulic running gear, as mentioned above, the drilling rig consists of two large drives (right and left side), consisting of an adjustable pump and hydraulic motor each, to achieve the purpose, features: - drilling rig for holding the vertical and / or horizontal wells, including basic driving a cart with a frame, propulsion stroke of the right and left sides, volume hydraulic pumps and hydraulic motors drive the propulsion of the right and left sides, established through the mechanism of the suspension frame feeder with drive mechanisms rotating drill rod along the axis of the bore with hydraulic motors drives these mechanisms, to provide a Parking brake mechanism control, and the hydraulic motor drives the rotation of the drilling rod and the fur is ISM its supply to be connected to the pumps of the right and left sides parallel to the hydraulic motors of the propulsion drives, through a two-position spools connected with the control mechanism of the Parking brakes.

It is also proposed mechanism control Parking brakes to perform the braking hydraulic cylinders and valve management, with a two-position valve to perform with hydraulic control, and the entrances to the camera control valve to connect the mains input to hydraulic brake cylinders Parking brake.

To ensure that, in addition to drilling vertical wells, drilling possibilities and(or) horizontal wells (for anchorage of walls to a minimum height from the bottom of the pit) the mechanism of the suspension rig is invited to perform in the form of a hinge with hydraulic tilt cylinder frame feeder, chetyrehzvennoy, anchor link which is transverse beam.

To allow horizontal drilling from either side of the base of the undercarriage features a frame feeder pin in the intermediate guide lever mechanism of the suspension with the possibility of its longitudinal movement, and a transverse beam of the suspension mechanism to perform symmetrical relative to the longitudinal plane of symmetry of the undercarriage.

The proposed schematic and layout solution allows to realize the goal, as much as what extent to use the energy capabilities of the underlying machine and to ensure safe operation of the drilling rig.

The best option of carrying out the invention

The rig consists of a base chassis (figure 1, 3 - 6), 25 which can be applied, for example multi-purpose municipal construction machine MKSM-800, frame 1, jet 2 stroke (tracked or wheeled), the driving motor of the machine (not shown), volume hydraulic drive (2) with pump units 3 and motor 4 drive propulsion of the right and left side of the Parking brake 5, and mounted drilling equipment (1, 3-6), as part of a frame of the sheet feeder 6, the drive mechanisms of the rotator 7 and drive feeder 8 drill rod (not shown). The frame of the feeder unit 6 mounted on the cross beam 9 of the suspension mechanism, through which the clamp device of the base of the machine is mounted on the boom 10 working equipped with the I basic machine. Thus, the mechanism of the suspension is made in the form of a hinge with hydraulic cylinder 20 of the tilt frame of the sheet feeder 6, chetyrehzvennoy formed by the pivoting arm 21 and the cylinder 20, a support link which is transverse beam 9.

The drive rotator 7 and the drive of the feeder unit 8 uses the hydraulic motors 11 and 12. The motors 11 and 12 (figure 2) is connected to the pump 3 volumetric hydraulic actuators of the right and left sides parallel to the hydraulic motors 4 drive of the respective propulsion through the dip spools 13, connected with the control mechanism of the Parking brakes 5 directly, or through the mechanism of the remote control. In this case, the control mechanism Parking brake 5 is, for example, with the valve 14 controls the brake hydraulic cylinders 15, and the on-off valve 13 are performed with cameras hydraulic control, and the entrances to the camera control spools are connected by roads with entrance to hydraulic brake cylinders 15 Parking brake 5.

As a means of ensuring the sustainability of the rig and security in the drilling rig is equipped with rear jacks 16 and front outriggers 17 and a valve 18 (2) management (including hydraulic cylinders 19 of the front outriggers).

To combine maybe the ti drilling (variant) vertical and(or) horizontal wells (for anchorage of walls of the pits at a minimum height from bottom), the frame of the sheet feeder 6 is fixed in the intermediate guide lever pivoted lever 21 with the possibility of longitudinal movement of the frame by a hydraulic cylinder 22, and the transverse beam is made symmetrical with respect to the longitudinal plane of symmetry of the undercarriage.

The cylinders 20 and 22, and the hydraulic cylinders 16 and 19 through the respective spools 18 and valve 23 is connected to 5 of the auxiliary pump 24 of the hydraulic system work equipment basic machine.

Self-propelled drilling rig operates as follows.

After installation on the source position for drilling vertical or horizontal wells included manual Parking brake (disc 14, figure 2), the installation hung on the rear support jacks 16 and front outriggers 17 (cylinders 19). This propulsion 2 (wheels) fades away and detached from the supporting surface, and instead of hydraulic motors 4 stroke pumping units 3 hydraulic suspension on the Parking brakes 5 connect the motors drives the rotator 11 and the sheet feeder 12 drill rod. Control speed and feed when drilling is carried out by modulation of the pumping units 3 turn the machine base through existing it management systems.

The transition to move (to a new initial position) preceded the surge is of the machine, the rise of the pillars of the jacks 16 and outriggers 17, mandatory disinhibition engines 2 stroke with simultaneous automatic connection to the pumping units 3 engines 4 stroke and off through the spools 13 hydraulic motors of rotation 11 and the feeder 12 drill rod. This eliminates the possibility of accidental activation of the stroke of the machine during drilling, and Vice versa - enabling mechanisms drilling during the movement of the machine.

The structure of the suspension is mounted drilling equipment provides for the connection of the transverse beams and shafts 10 by staff of the clamp device, which enables easy connection and disconnection of the drilling equipment from the base of the machine and replacing it with a different work equipment for performing other works.

When dismantling mounted drilling equipment line "drainage", "pressure", "discharge", between the base chassis of the truck and mounted drilling equipment, disconnect and lock valves, built-in quick-release connection of highways (figure 2, Ref. 25). Industrial applicability, thereby providing the maximum possible power to weight ratio of the rig when using as the base of the undercarriage of the machine of universal application, and maintaining the possibility of application in the production of other operations in the conditions of the same construction site, that significantly increases equipment utilization and reduces the time of his return.
