Description

Aggregates are known for mechanized mining of salt from the faces, spreading out at an angle of repose, mounted on a platform and having a loosening drum, located on the side of the platform.

The described wide-grip downhole aggregate for salt extraction differs from the known ones in that it consists of two disk actuators, which, by means of a winch, carry out reciprocating movement along the truss, hydraulic jacks for shifting and unfastening the truss, as well as a conveyor for transporting broken salt to the trolleys.

Such an embodiment of the wide grip aggregate makes it possible to increase salt production from one bottom and to increase labor productivity.

FIG. i depicted are described; wide-grip unit in the plan; in fig. 2 is a section along the line A-A in FIG. one.

The wide-hole bottomhole assembly consists of two executive bodies: 1 combines 2 3 types КР (without bar and loader) or К8Н (without upper breaker bar), which have increased diameter blades and increased cutting speed; carrier truss having an inclined part 4, located on the bottom, and horizontal - 5, mounted on the downhole scraper conveyor 6; a bend winch 7 and the feeding part 8 of the D-2 combine; hydraulic jacks 9 and 10 for moving the carrier truss and hydraulic jacks 11 and 12 for supplying the downhole conveyor with the carrier farm and the combines forward.

The inclined part of the carrying truss is assembled from separate sections and is a steel structure consisting of parallel guideways 13 and connecting strips 14. The upper end of the inclined part of the truss is fastened by a hydraulic jack - a sturdy 15 between the roof of the working and the inclined bottom of the breast.

The addition of salt by the aggregate is performed as follows. When the engine feed part 8 is turned on, for example, a right-hand combine 3 mounted on a farm, the rope 16 moves along the guide / BBepJf, destroying the bottom of his chest with his executive body by an amount of overhang of 0.1 m. position, the engine of the feeding part 5 is reversed and the hydraulic jack 17 of the combine is activated, lowering the front part of the combine together with the actuator by 0.1 m. The combine moves under its own weight to remove the salt strip to the lowest position and the horizontal part 5 of the farm. After that, the truss jacks 9 and 40 are moved to the left by the amount of gripping and the stand 15 is fastened between the roof and the face. The right harvester removes lanes until the farm is at a distance equal to the capture value of the left harvester 2 from the leftmost position. After this, combine 3 is installed on a horizontal platform and, having re-chained the cable 16, start working with the left combine 2, moving it with jacks until the truss is at a distance equal to the capture value of the combine 3 from the extreme right position. Supply of downhole conveyor with farm and combine Produced by hydraulic jacks 11 and 12, the rods of which abut anchor racks 18 and fix it in the development of self-braking wedges 19. Simultaneously with the movement of the conveyor, the U-shaped section of railway track 20 moves to its frame. Salt destroyed by gravity enters the downhole conveyor 5, from which it is discharged into trolleys 21.

To keep the combine on the truss, in the event of a rope break, the latter is attached to the paraschine 22, the lever of which, when rotated, abuts against the bottom or the truss. In addition, in order to prevent cable breakage, an electrical interlock is provided in the control circuit of the combine and feed section 8. The combine feed motors, downhole conveyor and oil station 23 are controlled remotely from the control panel 24. In addition to remote control of the feed motor, it is reversed and The JMoryT is stopped by a limit switch mounted on the feed part 5, which is activated by pressing its arm 25 arm of any combine (when it is at the extreme erhnem position. Stop the flow of the engine part is performed limit switch 26 which is triggered by acting on its arm 25 kronschteyna any harvester present in the lowermost position.

The reverse of the jack 10 is carried out manually with the help of a pawl mounted on the end of the jack rod, which abuts against the tides 27 located on the aboy conveyor 6 when the truss is in one of the extreme positions.

Subject invention

Wide-scale downhole aggregate for mechanized extraction of salt from faces located obliquely at an angle of repose, characterized in that, in order to mechanize the extraction of salt, increase labor productivity and increase the load on the bottom, the unit consists of two disk executive bodies of combines that can be returned back by means of a winch -accessive traffic along the farm; hydraulic jacks for shifting and unfastening the truss; as well as a conveyor for transporting chipped salt to the trolleys.
