1one

Изобретение относитс к буровой технике и может быть использовано дл бурени скважин под буронабивные сваи.The invention relates to a drilling technique and can be used for drilling wells for bored piles.

Известно устройство дл бурени скважин под буронабивные сваи, включающее базовую машину, на стреле которой подвешен электропривод с буровым инструментом, укрепленный на колонне, соединенной посредством каретки со стабилизатором, снабжен ным плитой с полой стойкой, при этом каретка установлена с .возможностью осевого перемещени относительно колонны fl .A device for drilling wells for bored piles is known, including a base machine, on the boom of which an electric drive with a drilling tool is suspended, mounted on a column connected by a carriage with a stabilizer, equipped with a plate with a hollow stand, and the carriage is installed with axial displacement relative to the column fl.

Недостатком этого устройства вл етс низка производительность труда при сооружении буронабивных свай.A disadvantage of this device is low productivity in the construction of bored piles.

Наиболее близким по технической сущности и достигаемому результату к изобретению вл етс устройство дл бурени скважин, включающее базовую машину со ctpeлoй, на которой подвешен привод,штанга с рабочим органом , установленна соосно в. стаби-; лизаторе, кондуктор, имеющий направл ющие и соединенный посредством фиксаторов с переходником 2 jThe closest in technical essence and the achieved result to the invention is a device for drilling wells, including a base machine with a directional drive, on which a drive is suspended, a rod with a working body, installed coaxially in. stable; lizator, jig, having guides and connected by means of clamps with an adapter 2 j

Недостатком этого устройства вл етс низка производительность труда из-за больших затрат времени на перестановку кондуктора и закреплени его анкерами.The disadvantage of this device is low labor productivity due to the time consuming to relocate the conductor and fasten it with anchors.

Целью изобретени вл етс повы10 шение производительности труда при строительстве скважин.The aim of the invention is to increase labor productivity in the construction of wells.

Claims

This goal is achieved by the fact that in the device including the base machine with the boom on which the drive is hung, the bar with the working body is installed coaxially in the stabilizer, the jig having the wrong bars and connected by means of retainers to the adapter guides the jigs in the form of a screw blade, and the latches are made in the form of a hook and a plate with a groove in which the hook is placed so that it can be rotated, with the plate attached to the jig and the hook on the adapter. FIG. 1 shows the device, the total bid; in fig. 2 - node 1 in figure 1; in fig. 3 section aa in FIG. 2, the jig is suspended on the boom); in fig. 4 - the same (immersion of the conductor in the ground and drilling); in figure 5. the same C before removing the conductor) On the boom 1 of the base machine 2, a drill stand consisting of water 3 with a current collector, a 5 square cross section stabilizer with an emphasis 6, a boom 7 with a working member 8, and an adapter 9 and a coil 10 1C with a helical blade 11, the direction of which is opposite to the direction of rotation of the working body 8 during drilling. The adapter 9 interacts with the stabilizer 5 by means of a hole 12 of square section, and with the conductor 10 by means of clamps, each of which consists of a hook 13 and a plate with a groove C, In the position when the drilling rig is suspended above the ground, there is a gap between the adapter 9 and the conductor 15. The drive is powered by a cable 16. The device operates as follows. The base machine 2 combines the axis of the working body with the axis of the well, and the drill is lowered onto the ground surface, while the gap 15 is eliminated, and the hook 15 leaves the hook with neither the 1L plate. The actuator 3 is turned on and the torque from the rod 7 is transmitted to the working member 8. The torque is sensed by the stabilizer 5 and the adapter 9, which is rotated and through the back side of the hook 13 and the plate transmits the torque to the conductor 10 (Fig. (). Conductor helical blade 11 It sinks into the ground. Since its resistance to immersion is much greater than the resistance to cutting of the soil by the working body, the axial recess of the conductor stops, and the working body 8 under the influence of the weight of the drill rod deepens Thus, the conductor secures the wellhead from collapsing and acts as a stabilizer of the actuator from the reactive moment. After filling the working body with soil, its rotation is stopped, and the entire drilling rig is lifted to the surface to unload the working body. After the well has been driven to a predetermined depth, the actuator 3 is switched to reverse rotation, the adapter 9 is rotated to its original position, the hook .13 acts on the plate AND, and the conductor is unscrewed from ground. The drilling rod is raised up, while the hook 13 enters the groove of the plate H, thus fixing the jig 10 with the adapter 9SFIG.Z). The use of a conductor in the device, equipped with a screw blade and a clamp made in the form of a hook and a plate t with a groove, allows the well to be drilled and the conductor installed at the same time, and the conductor does not need to be fixed with anchors, which increases the productivity of the wells. The invention is a device for drilling wells, including a base machine with an arrow on which a drive is suspended, a bar with a tool, mounted coaxially in a stabilizer, a jig having guides and connected by means of clamps with an adapter, characterized in that labor by reducing the time and to rearrange the conductor, the conductor guides are made in the form of a helical blade, and the latches are made in the form of a hook and a plate with a groove in which the hook is placed With this turn, pLastina is attached to the jig and hook to the adapter.
