The rings can be retracted into the grooves 18 of the disks 10, 11. The drum 4 rotates in the direction of the traffic flow, crushing elements 5 oversized pieces of rock. 2 Il. SL CO CA: 00 00 oo 00

Description

The invention of Otos GTS to the executive bodies of crushers installed in the openings of mines, and can be used in mining ores.

The purpose of the invention is to increase reliability and reduce the complexity of installation and disassembly in cramped conditions.

FIG. 1 shows the executive body, sectional view in FIG. 2, the stage of mounting the executive body.

The operating unit comprises a frame 1 with supports 2 and 3, a drum 4 with crushing elements 5 and a drive 6. Each of supports 2 and 3 has cantilevered support shafts 7 and 8. The drum 4 is made in the form of three discs - central 9 and two lateral 10 and 11 and of the stub shaft 12. Shafts 7, 8 and 12 can be slotted, keyed or other design with the possibility of transmitting torque. The side disks 10 and 11 are mounted simultaneously on the input shaft 12 and the supporting shafts 7 and

8 accordingly. Between disks 10,

9 and 11 are spaced segments or half-rings (segments) 13, on which rings 14 are attached. The latter are connected to segments 13 by a detachable connection, such as screw 15. On the opposite side, side disks 10 and 11 abut against supports 2 and 3 of frame 1, for example internal rings of rolling bearings through spacers 16 and 17 "At the ends of the side discs 10 and 11J facing the central disk 9, grooves 18 are made in which rings 14 can be placed.

The assembly (assembly) of the executive body is carried out as follows.

A central disk 9 is mounted on the input spline shaft 12, then disks 10 and 11 are successively mounted on both sides of the shaft. Rings 14 are inserted into the grooves 18 of these disks. Assembly of the disks with the shaft is inserted into the crusher coaxially with the supporting shafts 7 and 8 (FIG. 2). The disks 10 and 11 are moved apart to the sides and thus partially mounted on the supporting shafts 7 and 8. Then, spacer segments, 13, are inserted between the side 10 and 11 and the central 9 disks, which are removed from falling out of the rings 14,

with the grooves 18. The rings 14 on the segments 13 are fastened with screws 15. The dismantling of the actuator is carried out in the reverse order. The screws 15 are removed from the rings 14. The latter are pushed into the grooves 18 of the lateral discs 10 and 11, after which the segments 13 are removed. The lateral discs 10 and 11 are displaced to the central disc 9. At the same time, all the discs 9, 10 and 11 are on the stub shaft 12 .. Drum 4 is removed from the frame 1.

The executive body works as follows.

Rotation from the drive 6 through the support shaft 8 is transmitted through the side disc 11 to the support shaft 12, and from there to the discs 9 and 10. The segments 13, compressed between the discs 9, 10 and 11 and fixed by the rings 14, rotate together with the discs 9, 10 and 11. In the case of the use of an executive body in crushers of a downhole conveyor, the rotation of the drum 4 has a coordinated direction with the conveyor flow. The oversized coal pieces, which fall under the drum 4, are crushed by crushing elements 5 to a predetermined size, and the smaller coal pieces pass unhindered through the crusher.

In the event of a failure of one of the disks, only this disk is replaced, the others are not changed. At the same time, the transportation of discs is greatly simplified compared to the transportation of the entire drum of large shaft crushers.

The invention makes it possible to increase the reliability and reduce the laboriousness of mounting and dismounting the actuator in cramped downhole conditions.
