Description

The invention relates to mining, mainly coal, and is intended to maintain sections of the conveyor pitch of the conveyor at the level of the soil in the intersection zone of the average drift by a lava (three-way coal mining technology).

Known supporting devices are designed to maintain the drive of the conveyor at the soil level of lavas adjacent to the upper and lower drifts (two-way coal mining technologists), made in the form of a lining support table, including a frame with jacks and anchor, connected to the frame by rigid attachments, which adjusts the position of the conveyor drive at the lava soil level by removing or installing rigid spacers (l

However, these devices are designed to operate in the extraction of coal by two-liner technology and do not provide for the support of the conveyor grating at the soil level of the upper and lower parts of the lava adjacent to the middle drift of the three-liner coal mining technology.

The closest in technical essence and the achieved result

The invention is a device for supporting the pan-and-pitch conveyor with a three-line coal mining technology, comprising a frame made of longitudinally and transversely installed beams for locating the grating pillar and cable layer and hydropatron. At the same time, the device has a table guide, a platform

10 traveling jacks, thrust jacks, table lifting stands, distance ski, hydraulic locks, remote control. Nor and the system hydrostart 2.

However, this device does not ensure the adaptability of the conveyor pitch to the unevenness of the soil hypsometry of the end sections of the upper and lower parts of the lava adjacent to the drift road, since

20 visual fixation and fixation of a manometer. Heights of irregularities, changes in soil hypsometry, and ycTcages of the struts and hydraulic jacks on this sort of change are extremely difficult in mine conditions. As a result, the sections of the conveyor railing of the conveyor bend toward the undercutting of the drift soil or are squeezed out by a pin and hydroracks upward along an arcuate path. therefore, harvesters, when they are removed from the lava on the middle drift, are hacked into the soil or roof. The aim of the invention is to ensure the self-adaptability of the grate pitch of the conveyor to the soil hypsometry of the end sections of the lava adjacent to the middle drift. This goal is achieved by the fact that the device for supporting the pan-and-pitch conveyor with a three-piece mining technology-coal, containing the painy beams installed longitudinally and transversely, to accommodate the pan-grating sections and the cable spreader and hydraulic chassis, is fitted with a frame mounted on the longitudinally mounted beams of the frame. - a submersible shield and thrust panels mounted on transversely mounted frame beams, and the frame is equipped with additional beams connected to the lattice cTa sections and conveyor and cable layer. FIG. 1 shows a section A-A in FIG. 2 (device diagram, general view in Fig. 2 - view B in Fig. 1. The proposed device contains additional beams 1, 2 and 3 (Fig. 1 supported by ends on the soil 4 end sections of the upper 5 and lower b (Fig. 2 parts lavas, which are mounted on sections 7 (Fig. 1) of the pan-tilt stand of the conveyor 8 and sections 9 of the cable-laying machine 10 and connected to longitudinally mounted beams 11. Beams 11 are supported on transversely installed beams 12 and by means of kerchiefs 13 -dispore t g 14, 15 and 16 are articulated in a frame. Hydrojacks 17 through a rod-and 18 are connected to t-gami 19 20, on which a stop shield 21 is installed. In this case, the protective-immersion shield 20 is movably mounted on longitudinally mounted beams 11. The thrust plates 2 mounted on transversely mounted beams 12, hydropatrons 23 are ridden in lateral exposures 24 of the soil 4 of the average drift 25. On the beams 11, an adapter plate 26 is installed to ensure free passage of workers from one part of the lava to another.The beam 3 is provided with windows to accommodate the attachment points 27 for mounting hydraulic jacks for moving the armored support sections (not shown), and beam 2 includes a horizontally mounted support and two vertical supports 28 and 29 (FIG. 1), on one of which the guide support 30 of the combine is placed on. The device operates as follows. Initial position. The device is installed between the spacers of the support mating, located on the middle drift 25. At the same time, the end sections of the additional beams 1, 2 and 3 and connected to these sections of the section 7 of the grid station of the conveyor 8 and section 9 of the cable layer 10 are supported on the soil 4 end sections of the upper 5 and nizhia 6 parts of lava. Additional beams 1, 2 and 3, beams 11 and 12, interconnected by means of kerchiefs 13 and spacers t 14, 15 and 16 into the frame, ensure reliable support of the grate stand of the conveyor 8 and the combine after it has reached the middle drift 25 at ground level the end sections of the upper 5 and lower 6 parts of the lava. The barrier and submersible shield 20 is extended beyond the bottom line, the hydraulic jacks 17 are open, the shields 22 are unfolded by hydraulic cartridges 23 to the lateral exposures 24 of the middle drift soil 25 and prevent their rupture and outflow of soil rocks. At the same time, the shields 22 keep the device and, consequently, the occasional positioning of the conveyor 8 with the cable layer 10 from sliding towards the lower part of the lava. After the withdrawal of combines. For example, from the lower part 6 of the lava to the lower drift, and from the upper part 5 of the lava to the middle drift, 25 hydraulic jacks for moving the sections of the lava support make frontal movement of the conveyor, and together with. The device is moved by the step of moving to the surface of the clearing flank. The device is then moved by hydraulic jacks of the end sections of the lateral support or hydraulic jacks of the berm sections of the support pair without loss of contact of the spacer shields 22 with lateral exposures 24 of the soil drift 25. The removal of combines from the lower part 6 of the lava to the middle drift 25, and from the upper part 5 of the lava to the upper drift, the front movement of the conveyor and supporting device repeats. In the initial position and during the movement, the end sections of the beams 1, 2 and 3 and the sections 7 of the conveyor pitch are connected with their own weight, the weight of the coal and lump. The pressing end 4 of the upper 5 and lower 6 Parts of the lava is copied their irregularities, i.e. self-adapting to irregularities and changes in hypsometry without a person participating in this process, as well as mechanisms in the form of spacer-supporting hydraulic, mechanical and other devices. In the event that the withdrawal of combines on the middle drift 25 is accompanied by coal and roof rock outfalls at the end sections of the lava, then the mass falling out into the middle drift 25 of the hearth accumulates on the protective-submersible shield 20, which, according to the measure of necessity, is moved by means of hydraulic jacks 17 to the right. In the process of moving the containment shield 20 to the right, the stop shield 21 moves the accumulated rock mass to the conveyor and loads it onto the conveyor, after which the hydraulic jacks 17 return to the initial position and the loading cycle of the rock mass repeats as it accumulates on the indicated shield.

The proposed device ensures reliable maintenance of the conveyor panning at the soil level of the end sections of the lava adjacent to the middle drift, and its self-adaptability to unevenness and changes in the soil hypsometry of these sections; operation of the device in the middle drifts with different depths of the lower demolition, collection and mechanical loading on the conveyor of rock mass that fell out on the end sections of the lava; Keeping the conveyor pans from sliding down due to the spreading of spacer shields to the lateral outcrops of the middle drift J improves working conditions and increases the safety of workers when carrying out assembly and dismantling works on the middle drift, as well as transporting equipment to the lava and back by introducing into the construction - submersible and transitional shields.
