Изобретение относитс к области горной промышленности и может быть применено при бурении пшуров под анкерную крепь.The invention relates to the field of the mining industry and can be applied when drilling holes for anchor bolts.

Известно устройство дл бурени восстающих шпуров, состо щее не трубчатых колонок, по которым, перемещаетс каретка при движении вниз расположенных в колонках поршней, соединенных с кареткой тросом .A device is known for drilling of recurring holes, consisting of non-tubular columns, through which the carriage moves when moving downwardly located in the columns of the pistons connected to the carriage by a cable.

Недостатком этого устройства вл етс нсзсзмохсйость бурени шпуров на liuiitiyKj длину штанги.A disadvantage of this device is the improper drilling of holes for liuiitiyKj rod length.

Наиболее близкой по технической сущности вл етс установка дл бурени шпуров под анкерную крепь, .включающа телескопические трубы, каретку, вьтолненную с возможностью перемещени по трубе, сверло с приводом подачи с помощью каната , который закреплен в нижней части выдвижной трубы, навравл ющие ролики в верхней части неподвижной трубы, снабженной опорной п той .The closest to the technical essence is the installation for drilling holes for anchor bolts, including telescopic tubes, a carriage that can be moved along the tube, a drill with a feed drive using a rope fixed in the lower part of the retractable tube, roll rollers in the upper part of the fixed pipe, provided with a support p.

Недс)статком этой установки вл етс Невозможность бурени шпуров :на полную длину штанга в выработках различной вы сотой.The statistics of this installation is the impossibility of drilling holes: for the full length of the rod in the workings of various heights.

Целью изобретени вл етс обеспечение возможности бурени шпуров на полнуй длину штанги в выработках различной высоты с одновременным созданием необходимого распора.The aim of the invention is to provide the possibility of drilling holes for the full length of the rod in the workings of different height while creating the necessary thrust.

Это достигаетс тем, что в верхней и , нижней част х выдвижной трубы установки дл бурени шпуров под анкерную крепь установлены направл ющие ролики.This is achieved in that the guide rollers are installed under the anchor bolt in the upper and lower parts of the extendable pipe of the drilling installation.

На фиг. 1 изображена предложенна установка, общий вид; на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows the proposed installation, a general view; in fig. 2 is a section A-A in FIG. one.

Claims

The installation contains a stationary cylindrical tube 1, a free entrance to the schU (about the inside of the tube 2 (telescopic tubes) along which the carriage 3 moves with a drive 4, the drive has a feed drum 5 on which a rope 6 is wound, covering rollers 7-9 mounted on a retractable tube 2, and the roller 10, located in the upper part of the fixed pipe 1, the free end of the rope is rigidly fixed to the lower end of the pipe 2, the drill rod 11 is inserted into the spindle of the drive, passing through the sealing ring of the dust collector 12. Elliptical flange 13 fyk The pipe operates as follows: The initial installation of the device, which is in a vertical position, occurs under the action of the weight of the drive, which creates tension on the rope 6. When considering the equilibrium of the movable pipe, it is clear that the forces acting on the tube from the roller 9 side are equal and oppositely directed, and therefore they balance each other. But since the tube 2 is additionally exerted by an additional force from the rope pipe fixed to the bottom end, which is upwards, the installation starts between the roof and the soil with a force equal to the tension of the rope 6. The supply of the drill rod to the wagon in the proposed installation occurs by pushing the drive with the rod along a fixed rope, which senses the force of spinning of the drill string from the bottom and automatically ejects installation in the excavation. As the driven carriage moves along a retractable pipe that has constant contact with the roof, the hole is always drilled to the same depth (well. The latter will precisely control the depth of the drill hole when the working height is changed and use the full length of the drill rod to drill labor costs and auxiliary operations that were manually performed in previously applied installations are eliminated. Formula of the Invention The installation for drilling holes under anchor bolts, including telescopic tubes, carriage, filled with the ability to move along a pipe, a drill with a feed drive using a rope fixed in the lower part of the retractable pipe, and guide rollers in the upper part of the non-extension pipe equipped with a support heel, in order to enable the drilling of bore holes on the full length of the shtangi in the workings of different height with the simultaneous creation of the necessary thrust, the guide rollers are installed in the upper and lower parts of the sliding pipe.
