Изобретение относитс к горной про . мьгашенности, в частности к устройствам дл бурени скважин.;This invention relates to a mining pro. obstacles, in particular to devices for drilling wells .;

Известен буревой станок, включающий раму, направл ющие, в которых смонтирован подвижный вращатель, жестко соединенные с нижней траверсой, а поисковые скалки - с верхней траверсой. При этом поисковые скалки смонтированы в направЛ5ПОШИХ и соединены с нижней траверсой при помощи цилиндров выдвижени , а по ски скалок взаимосв заны с вращателем и имеют одинаковый профиль с поверхност ми направл ющих ft.There is a known borax machine, which includes a frame, guides, in which a movable rotator is mounted, rigidly connected to the lower crosshead, and search rods - from the upper crosshead. At the same time, the search rods are mounted in the direction of the FLOW and connected to the lower traverse by means of extension cylinders, and by skipping the rollers are interconnected with the rotator and have the same profile with the surfaces of the guides ft.

К недостаткам этого станка относитс небольща величина хода непрерывной подачи, котора ограничена длиной направЛ5ПОЩИХ и скольз щих по ним втулок вращател . Увеличение хода цилиндров выдвижени при неизменном транспортном габарите станка приводит к увеличению длины втулок вращател ,The disadvantages of this machine include the small size of the continuous feed stroke, which is limited by the length of the guide and the sliding sleeves of the rotator. An increase in the stroke of the extension cylinders with a constant machine envelope leads to an increase in the length of the sleeves of the rotator,

Наиболее близким к предлагаемому по технической сущности и достигаемому результату вл етс буровой станок, включающий податчик, переднюю и заднюю траClosest to the proposed technical essence and the achieved result is a drilling machine, including feeder, front and rear tracts

версы с закрепленными в них штоками силовых цилиндров, вращатель, св занный с корпусами силовых цилиндров, шгоки которых закреплены в передней траверсеГз. Недостатки известного станка заключаютс в сложности конструкции и больших транспортных габаритах.Versions with rods of power cylinders fastened in them; a rotator associated with the housings of the power cylinders, which are clamped in the front traverse. The disadvantages of the known machine are the complexity of the design and large transport dimensions.

Цель изобретени - уменьшение транспортных габаритов и упрощение конструкции .The purpose of the invention is to reduce the transport dimensions and simplify the design.

Claims

15 front and rear crossheads with power cylinder rods fixed in them, a rotator connected to power cylinder bodies whose rods are fixed in the front cross bar, rods fixed in the front cross bar, are made in the form of power cylinders in which the pistons of the rods fixed in erdney traverse. The drawing shows a drilling rig c saHOK, longitudinal section. The drilling machine has a frame that is made of the rear I and the front 2 engraver, with which the guides 3 are very rigidly connected in the form of power tsipindra, whose bolts are fixed in the rear traverse I. In the guides 3 there is a rolling pin 4, which is a piston cylinder. A rotator 5 with a drilling tool 6 is mounted on the outer surfaces of the guides 3. A feed hydraulic cylinder 7 is fixed on the upper traverse I, the rod of which is connected to; the rotator 5- Rolling pins 4 are made in the form of 8 extensions of hydrocladder, the rods of which are connected to the rear cross-bar I. The axial force developed by the feed cylinder 7 is equal to the total force developed by the extension cylinders 8; The drilling rig works as follows,; An axial axially lugging drilling tool 6 is initially created on the face by a feed cylinder 7. At the same time, the rotator 5 by the drilling tool 6 is mixed in the direction 3 of the movable crosshead I from the upper position to the horizontal, i.e., by the stroke of the cylinder 7. traverse 1 and guides 3 and cylinder 7 fixed on it. The initial axial pressure on the bottom can be created on 8 extensions. In this case, the supply hydraulic head 7 is activated after operation. The elevator of the rotator 5 with the drilling tool 6 is carried out in reverse order. To reduce the auxiliary time by accelerating the movement of the rotator with the tool, it is advisable for. feed and feed hydraulic extensions use separate hydraulic pumps. The proposed drilling machine implementation will allow to increase the continuous feed stroke while reducing the machine envelope size, since the rotator can move here along the guides, along with them. The invention The boring machine, which includes a feeder, a front and rear crosshead with rods of power cylinders fixed in them, a rotator associated with power tsiperndor hinges, Shto1si which are fixed in the front crossmember, and that , in order to reduce transport dimensions and simplify compxuKii, the rods fixed in the front traverse are made in the form of power cylinders in which the pistons of the rods fixed in the rear traverse are placed.
