Description

Boulder cutting machines are known to be mounted on a carriage moving along the rails, with circular saws and using calipers to allow the saw carriers to move in horizontal and vertical directions. The proposed shell cutting machine consists of three sections mounted on a common platform moving along rails. Each section consists of a caliper with circular saws and an electric motor. Suportov through screws and hovich-. They allow you to manually move the saws perpendicular to the track and upwards. All saws on all sections (caliper) are disk saws; the first section carries a rear saw with an axle on which cutters (cones) are mounted; the second section is equipped with two horizontal saws; the third section carries intermediate horizontal saws, with the middle saw set obliquely to produce a wide cut for shaft passage. There are no saws for vertical cutting.

platforms for moving the machine to the rock; FIG. 5 is the same, front view.

The machine (Fig. 1-3) consists of a movable platform 7j on which on the plate, in the form of a Suaort, there are three sections of the machine A, B, C, having a direct movement across the carriage stroke by means of screws 2, 3 and 4, which are would bed each section.

Section A consists of a circular saw 5, a shaft 6, a bearing 7, a lifting screw 8, a pulley 9, a driving pulley JO and a support bracket. The saw 5 is driven by an electric motor 12 mounted separately on the platform / by means of a pair of bevel gears / 5 and gear wheels 14 and 75. The latter sits tightly on the shaft 16 and rotates the JO screw, which through the belt drive / 7 and pulley 9 drives the Saw 5, mounted on shaft 6.

Section B consists of a vertical shaft fs, at the ends of which are mounted circular saws J9 and J9a, pulleys 20,21, 21a, 22, electric motor 23 and support bracket 24. Saws 19 and 19a are driven from motor 23 via a belt drive 24 and pulleys 20, 21, 21a

and 22. The shaft 18 with saws 19 and / Pa, when transporting the entire installation, is lifted from the manual action of the steering wheel 25, the screw 25, the screw wheel 27 and the rail 28, cut into the sleeve. Upon final installation of the saw, the vertical shaft 18 is clamped

29B is a section through the lower end of the caliper bracket sleeve 24..

Section C consists of a vertical shaft 30, three circular saws 31, 31 (1 and 31b, a vibrating pair of bevel gears 32, a shaft 33, pulleys 34 and 35, a motor 36 and a support bracket 37. Shaft

30s with saws. 31, 31a, and 31b are driven from electric motor 36 through pulleys 34 1 and 35 by means of a belt drive and a pair of bevel gears 32. The middle disc saw 31a is set obliquely, so that, with i vibrating rotation, it produces a ditch in the rock equal in height to the diameter of the shaft b, for its passage. In addition, for cleaning the ditch on the shaft 6 is still wearing the cutter 38.

The working filed of saws is produced automatically from the motor / 2, through bevel gears J3 of the worm gear in the box 9 (gear reducer of a pair of gear wheels (, star gear / k41 a, chain 42,

the shaft of the carriage and two pairs of tapered gears 44 and 45.

PI.Ch does not have vertical cuts. Means for approaching the machine with the platform to the rock is an ordinary platform e rails 46 (Fig. 4 and 5), which is installed on two slopes of small rollers 7, rolling along rails 48 laid slightly below pa6o% ix rails 49.

Redmet and inventions.

A shell cutting machine mounted on a trolley moving along a track with circular saws, using calipers that allow brackets carrying the saws to move in horizontal and vertical directions, characterized in that three sections A, B C (Figs. 1, 2 and 3) with three calipers, with a disk plate 5 on the L-section supor, with saws 19 and 19a on the J5 section supor and with 30, 31a and 31b saws on the C-section sup, and on the saw axis 5 cutters 38 are mounted, and the saw 31a is mounted obliquely to hold more its wider the cut, dopuskyyuschego shaft passage 6 with aligning 9schimi kerf cutters 38.
