(54) DRILLING MECHANISM

I

The invention relates to the mining industry, in particular to the feeding mechanisms of drilling machines.

A well-known mechanism is a pit drill rig, including longitudinal guides, hydraulic cylinder, traverse and slider | 11.

The disadvantage of the mechanism is a large dlc.

The most blizkimi to the technical essence and the achieved result to the proposed is the drilling machine feed mechanism, including longitudinal guides, hydraulic cylinder, valuable polyenact and traverse, made in vnde osn with asterisks | 2. .

A disadvantage of the mechanism is the difficulty of installation and disassembly.

The purpose of the invention is to simplify installation and dismantling.

The goal is achieved by the fact that the traverse is made with cylindrical supports mounted in sliders that are mounted in longitudinal guides. FIG. I shows the mechanism of the inn, vnd above; in fig. 2 - the same, etc. on the side

on fng. 3 is a section A-A in FIG. Iv and FIG. 4 - section BB in fng. 3, in FIG. 5 - Sechenne BB in fng. 3

The feed mechanism includes a frame 1, the upper part of which is equipped with a carriage

 2, on which the rotator is mounted (e is shown). On the sides of the frame, there are made longitudinal guides 3, in which the sliders 4 of the traverse 5 are installed. The mechanism of the drive force of the rail is 6

, on the traverse 7. On the traverse 5 on the subassemblies 8, there are two asterisks 9, which are fired by the chain 10 of the forward stroke, and an asterisk 11, which is fired by the chain 12 of the reverse stroke. The ends of these chains are fastened on one side to KapetKe 2, and on the other in frame 1.

ts Thus, a polyspast system consisting of motionless eves is obtained; 13 n 14 n daughters 9 n movable, 2 traverse n n 10, 12, with a front end equal to 2. The end of chains 10 is connected to frame 1 by means of viitst 15. On traverse 5, 16 is made to connect it with utah com 7 through the figured hole 17. Traver sa nest shistirannk 18, and in supports M mounted clamps 19, included in fixing holes 20. which correspond to the installation of the hydraulic cylinder 6 and its operation during reciprocating rod 7. Traverse 5 is discharged as an axis with movable asterisks of a polyspast indricheskimi supports 21 slides. The mechanism works as follows. When pressure is applied to the piston cylinder of the hydraulic cylinder 6, the rod 7 moves the yoke 5 backward (in Figs. I and 2 upwards) of the chain 10 of the forward stroke and moves the carriage 2 forward (in Figures I and 2 - down). Due to the fact that the end of the chain 10 connected to the screw 15 is fixed when moving the movable sprockets 9, its other end moves by an amount twice as large as the stroke of the rod 7, but with a reinforcement being twice as small. Thus, the carriage (forward) stroke of the carriage 2 is carried out. With this movement, the return chain 12 without an amplifier rolls on the sprocket 11, preparing the polyspast system for the carriage reverse travel, which occurs when pressure is fed into the rod cavity of the hydraulic cylinder 6. Rod 7 moves the yoke 5 forward (in Fig. 1 and 2 - down) H chain 12 reverse moves the carriage 2 backward (in Fig. 1 and 2 - up). Chains to freely roll over movable sprockets 9. Different directions of rotation of movable sprockets 9 and 11 are provided by mounting them on bearings 8. Removing the feed mechanism of hydraulic cylinder 6 without disturbing the stability of the circuits is as follows. The key for the hexagon 18 of the yoke 5 is rotated around its axis until the flats 16 are parallel to the grooves of the figured hole 17 in the rod 7. This position is fixed by the locking pin 19 through the hole 20 in the support of the traverse. After the combined baldness and grooves, the hydraulic cylinder 6 is raised so that the shaped holes 17 of the bald faces 16. and then removed from the mechanism. Application of the proposed mechanism allows to simplify installation and dismantling works. The invention The mechanism for supplying a drilling machine, including longitudinal guides, hydraulic cylinder, chain polyspast, traverse, made in the form of an axis with sprockets, characterized in that, in order to simplify installation and dismantling works, the traverse is made with cylindrical supports installed in sliders mounted in longitudinal guides.
