Description

12456922

The invention relates to the mining industry along the oil pipe 4 into the cavity of hydroline, in particular to devices for cylinder 2 moves the rod 5, and after drilling holes in rocks, it allows the shaft 11 and coupling 12 in the sidewalk to drill a single drilling hole. (from right to left). In this shaft, without replacing it with another longer moment of operation of the drill bit, the borax rod as the hole is deepened. 5, the rod 11 is fed aside

The purpose of the invention is to increase the production due to the movement of the rod 5, and due to

the drilling rate by reducing the movement of the sleeve 12 relative to this

time for auxiliary operations of the trickle through the thread because

intercepting the drill shtangi. coupled coupling nut 15 is coupled with the tailor FIG. 1 proposed drill (pro-th combo drill rod.

a partial cut along the axis of the chuck and hydro- When the rod 11 contacts the cylinder bore with the rod) in the initial position, an axial force arises on it, which also intercepts the rod 13 and acts on the bearing 13 and spring the chuck and its chuck 14, squeezing it until the rocker returns to its original position from the drilled-horn contact with the nut 15, and the drill hole doesn’t disengage from the half of the muzzle during the reverse rotation; in fig. 2 - the same position 16.

when drilling after the first stroke of the brush, after disconnecting the coupling half 16 with its length, the cable 15, the latter stops rotating with the spring 14, as a result the drill for drilling rocks of the drilling rod 11, jn, rotates from the rotational drive 1 and feed, guides with half coupling 16, is moved to cylinder 2 with oil lines 3 and 4, empty only by moving rod 5 of body 5 with internal right thread. This position of the drill corresponds to a fight along its entire length, outer over-fig. 2

The piston 6 is rigidly fixed after drilling the hole to the depth, the ramie support 7, located in the longitudinal groove of the rod 5 (its leftmost protective casing 8 with the possibility of its placement in Fig. 2), it returns

moving along this casing, for holding-to the starting position (fig. 1) by

no stem from possible rotation of the working fluid in a hydrocyon with two slots, rigidly connected bolt 2 through the oil pipe 3. At the same time, the gear 10, the drill rod 11 merges on the rod 11 and changes its direction with longitudinal slots that enter into the opposite direction as under the action pruoednie with the slots of the cartridge, camlock 14, and under the action of resistive coupling 12, rigidly connected to the tail end of the bottom and closes the clutch 12, resulting in the rod with the possibility of uncoupling the nut 15 rotates together with the drill during drilling under the action of the axial rod 11 and moves together

It is necessary to force the rod or clutch after this rod to the side, not to mollify the wave from the hole at the moment of interception of the drill rod. This is how it was pulled from the drilled Shpurovodits interception of the drill rod 11 after
