Description

one

The invention relates to mining engineering and can be used in the construction of stone cutting machines with a working body in the form of a flexible cable.

The purpose of the invention is to increase the reliability and simplify the design of the feed mechanism of the rod of the working stand of the wire saw.

With the rod 21, the cam clutch 22 with the ratchet wheel 30, which is loosely mounted on the eccentric shaft 12, engages in engagement. From the generator 8, they are pulsed through the current input 25 and are applied to the winding 24 of the electromagnet and the electromagnet bore 26 is drawn. In this case, the pawl 27 mounted on the bark of the electromagnet rotates the ratchet wheel 30 and the clutch 22, which with the help of the rod 21

rods with guide element, common 10 drives the input shaft into rotation; in fig. 2 - a reducer with a pulse electromagnetic engine; in fig. 3 shows section A-A in FIG. 2

The feed unit of the rod carrying the guide member of the working stand of the wire saw includes a support column 1 with a notched gear 2, a collet clamp with clamps 3, a rod with a guide element 4, a carriage 5, a gearbox 6 with a pulse electromagnetic motor 7, a generator of 8 pulses, pinion gear 9 and handwheel 10. The casing 11 of the gearbox b contains an eccentric shaft 12, bristles 13 and 14, rims 15 and 16. The crown 16 is made integral with the output shaft 17, on

torus (eccentric shaft 12) and gears 13 and 14 run around rims 15 and 16. At the same time, due to the difference in the number of teeth of gears 13 and 14, the rim 16 is displaced relative to the rim 15. This ensures rotation of the output shaft 17 with the wheel gear 9, which is included into engagement with the rack and moves the carriage 5 with the rod 4 installed in the collet chuck 3 in the required direction.

The locking device 31 limits the return stroke of the ratchet wheel 30. During the absence of current in the electromagnet winding, the spring 28 returns the measles to its original position. Using generator 8

in which the creamer toothbrush is attached - 25 pulses change time between im 9. The eccentric shaft 12 has an axial hole a and a diametrical through groove b. A pin 18, a spring 19 and a screw stop 20 are installed in the axial hole a.

Pulsed electromagnetic motor 7 includes a housing 23 of an electromagnet, a winding 24 of an electromagnet with a current input 25, a measles 26 of an electromagnet with a dog 27 and a return spring 28.

A ratchet wheel 30 is freely mounted on the input shaft of the gearbox 29 inside the housing 29, and a locking device 31 is mounted outside the housing 29.

The device works as follows.

In order to feed the bar manually when setting up the working stand of the wire saw for sawing, it is necessary to disconnect the current input 25 from the generator 8 pulses and remove the cam sleeve 22 from the latch jJ with the ratchet wheel 30. Then, at the exit of the eccentric shaft 12, the handle 10 is attached and rotating the latter is provided with a boom with a guide element in the desired direction.

In this case, the pawl 27 mounted on the bark of the electromagnet rotates the ratchet wheel 30 and the clutch 22, which with the help of the rod 21

10 causes the input shaft to rotate and reduce the input shaft of the gearbox (eccentric shaft 12) and the gears 13 and 14 run around the rims 15 and 16. The difference in the number of gear teeth 13 and 14 causes the crown 16 to shift relative to the crown 15. This provides rotation of the output shaft 17 with the gear wheel 9, which engages with the rack wheel and moves the carriage 5 from the rod 4 installed in the collet clamp 3 in the required direction.
