Description

(54) TRAINING MACHINE

I

The invention relates to mining machines intended to undermine the swelling of the soil in the mine workings equipped with rail tracks and main conveyors.

A known machine for cleaning the haulage and drainage grooves, comprising a chassis with a conveyor system, one conveyor with a paddle scraper mounted on the carriage on the guide, and the other conveyor is designed to clean the groove D. LY, cleaning track 1.

However, this machine can not produce undermining of the soil under railroad rails MI and trunk conveyors, as well as to carry out the drainage groove.

The closest to the proposed invention in terms of technical drying and the achieved result is a device for undermining the soil of the tracks, including a platform, an actuator with a drive and a curved cutting bar, a feed part, a conveyor and rail grippers 2.

The aim of the invention is to reduce the time of transfer of the machine to the working and transport position and to ensure the possibility of working on demolishing the soil of two road workings and the soil under the conveyors.

This is achieved by the fact that the platform is equipped with hydraulic jacks and a swinging arm, which have pivotal arms at the ends connected by pins with an actuator actuator.

A feed part, one of the levers being pivotally connected by a hydraulic jack with a rocker arm hub, which is connected with a hydraulic jack with a bracket equipped with a transverse movement mechanism, and the conveyor is made with a drum equipped with

cutters, and is provided with a hydraulic jack for longitudinal movement of the actuator drive and a hydraulic jack with a ski, which changes the angle of inclination of the conveyor axis to the working soil.

FIG. 1 shows a car, side view; in fig. 2 - the same, top view; in fig. 3 section A-A in FIG. 2; in fig. 4 is a section BB in FIG. 2; in fig. 5 - the same, front view.

Patching machine consists of feed part 1, engine 2, gear 3 cutting 1; aunt with a curved cutting bar 4 connected by a scraper conveyor 5 by means of four supporting skis 6, a cutting drum 7, which is an integral part of the conveyor 5, a supporting ski with a hydraulic jack 8 of the actuator 9, a hydraulic jack 10 shifting the actuator fixed at one end on the gear 3 of the executive organ and the other on the conveyor 5, pivoting levers 11 and 12 interconnected by a hinge 13 and secured with pins 14 on the gearbox 3 of the actuator and the feed part 1 and at the ends of the rocker arm 15, closed heated on the arm 16, a hydraulic jack 17 for lifting the machine fixed on the hub of the swinging rocker, 15, a hydraulic jack 18 adjusting the position of the rocker fixed on the bracket 16 and the hub of the rocker arm 15, a gear-drive mechanism 19 of lateral movement mounted on the carriage 20 of the bracket 6, fixing axis 21, a guide frame 22 mounted on the platform 23, hydraulic jacks 24 lifting the platform fixed pivotally on the platform 23, rails EH grippers 25 also pivotally fixed on the platform 23, the rail 26.

Works traversing machine} as follows.

Rail grippers 25 are closed at the heads of rail 26, the locking axle 21 is lifted and the mechanism 19 is turned on, by which the machine (engine actuator, feeding part with conveyor) moves along the guides of the bed 22 of the platform 23 in the direction of the output unit, where the manna is lowered onto the ground. And And 12 with the help of the hydraulic jack 17. Then, turning on hinges, the hydraulic jacks 24 of the platform lift are mounted on the ground. The platform 23 and the spike-rail grid are lifted by hydraulic jacks 24 and 17. At the end of the ascent, the pelvic rail grid (lays out the cages) is placed under the rail-rail grid and the hydraulic bar is placed in the gearbox 3 of the cutting organ , raise the jacks 24, release the grippers 25 and set them in the transport position. Then, a hydraulic jack 8 with a supporting ski and a hydraulic jack 18 for adjusting the position of the crustal 15 takes the position of the conveyor 5 at an angle relative to the soil when the cutting member is engaged with the feed part and the notch of the bent bar 4 begins with the cutting drum 7.

Upon reaching a predetermined depth and flattening to a horizontal position of the conveyor 5, the executive body 3 with the engine 2, feed part 1 and supporting skis 6 moves towards the middle of the conveyor 5 so that the working branch of the cutting chain is located behind the cutting drum 7.

With the end of the operations listed above, the maschina is ready for demolishing the soil.

The machine is moved to the transport position in reverse order.

The transportation of the broken rock mass from under the slot-rail grid is carried out by the cutting chain of the cutting bar 4 to the conveyor 5. In addition, the same mass conveyor 5 transports the hot mass, which is beaten off by the cutting drum 7.

Connecting the actuator to the platform by means of a swinging rocker, equipped with a mechanism of lateral movement, allows you to quickly move the machine into the working-position and transport without any assembly and repair;

The fact that the conveyor has a cutting drum makes it possible to reduce the loading of the broken rock mass and to re-enter the gutter.

The implementation of the rocker arm 15 by swinging the floating position of the hydraulic jack 17 and the presence of the hydraulic jack 8 with the ski at the conveyor allows you to cut, flatten the machine without transferring horizontal forces to the platform.

The fact that the platform of hydraulic jacks for lifting 24 grippers of the rail 25 allows, in combination with the hydraulic jack 17 for lifting the maschina, to lift the slot-rail grill and transfer the cutting drum 4 to the working position without prior notching.

In addition, the proposed machine design permits work to be carried out by demolishing the soil in two track workings and the soil under the belt and other conveyors.
