FIG. 1 shows a plot in plan; on ft. 2 - section A - A in FIG. 1; in fig. 3 is a view B in FIG. 2

The section contains a roller table 1 with rollers 2, a movable portal 3 is installed above the roller table, on rails 4 of which a carriage 5 is installed with a fire-fighting tool 6, between rollers 2 of roller table 1 is placed a lifting frame 7 with rails 8, which have a cart 9 with table 10 , equipped with a T-neck 11 in the tabletop, the shelves which are parallel to the Yush direction, 8 by its hole 12 in the wall, the reticle 13 and the collector 14, plate 15 is placed on the roller table 1, sample 16 is expressed on the table 10 15. On the side of the roller table 1 on Stir the flat table 10 and stalkivatel17 conveying traveler 8, np.w this table is a roller table 2 faces nizhe.urovn 1.

The dimensions of the rectangular part of the T-shaped notch 11 are larger than the maximum dimensions of the width and length of the sample 16.

The lifting frame / is equipped with a 1/1 water valve in the form of a hydraulic cylinder 19, levers 20 connected by a pull 21 mounted on racks 22, and the Trolley 9 is equipped with a & 23 actuator 23. In the roller table 1, exhaust boxes Lu- and 24 are located.

Works plot as follows.

Cutting the sample 16 can be carried out depending on the thickness of the sheet 15 in two ways.

In the first case, with relatively thin sheets, it can be realized; / 1ganie list inside its perimeter. In

the second case with thicker sheets,

It is not possible to burn a sheet and it is necessary to begin cutting the sample from the edge of the sheet.

In the first case, the work is as follows.

In the initial position, the cutting tool b is located above one angle of the rectangular part of the hole 11 in the table top of the receiving table 10 and in a predetermined position relative to the axes of the roller table 1. The reticle 13 provides control of the correct position and

subsequent movements.

 Coming on the longitudinal axis of the roller table 1. 15, the pulse from the front end of the end of the sensor (not shown) stops so that the place from which it must

The sample 16 is cut out above the hole 11 in the countertop of the receiving post 1C. After burning the holes in sheet 15, naminates. H move on the portal 3 carriages B with fire-fighting tool 6 and

the first (parallel to the axis of the roller of the roller table) is cut, the edge of the sample 16, When the cutting is completed, the movement stops. opening 5 and moving the gantry 3 with the cutting of the second side (parallel to the center axis of the roller table). Then the portal 3 stops and starts moving the carriage 5, only in the opposite direction, with the third face of the sample 16.

cuttings of the third face of sample 16, the carriage 5 stops and begins moving the carriages 9 with the receiving (table 10 by the stroke value, slightly less than the length of the largest sample. After moving the cart 9 with the receiving table 10 quarter (nb still cut through) the face 16 of the sample appears above the hole 11 in table 1, and sample 16 itself is above table 10. Then, by moving portal 3 (by returning

its initial position) is cut through the last, fourth side of the sample 16.

In the second case, the work is as follows.

The sample 16 is cut from the edge of the sheet 15 closest to the sample 16. In the initial position, the trolley 9 with the receiving table 10 is in a predetermined position relative to the longitudinal axis of the roller table 1, and the carriage 5 with fire-fighting tool 6 at the edge of the sheet 16 is above one of the shelves apertures 11 in the table top of the receiving table 10. In this case, the reticle 13 ensures control of the correct position and movement. The impulse 15 coming along the longitudinal axis of the roller table 1 from the front end stops so that the place of the sheet 15 from which the sample 16 is to be cut is above the rectangular part of the hole .11 in the table top of the receiving table 10. The movement of the carriage 5 with incision is next on sheet 15. After cutting to a predetermined length, the carriage 5 stops and starts moving the portal 3 with cutting the sample face 16. Then the portal 3 stops and again the carriage 5 moves, only in the opposite direction, cutting through the third Ani samples 16. Finished. cutting the third face, sample 16, the carriage 5 with the fire-fighting tool 6 stops, and the cart 9 with the receiving table 10 starts moving and, having made a move, But a value slightly less than the length of the largest sample 16 stops so that the fourth, not yet cut edge of the sample 16. renders with a hole 11 in the table top 10, and the sample 16 itself above the table 10.

Then, by moving portal 3 (returning it to its original position), the last, fourth edge of sample 16 is cut. Sample 16, separated from sheet 15, falls on table 10.

The size of the gap between the table top 10 and the sheet 15 is equal to or greater than the width of the cut, so that sample 16 does not get stuck in the cut hole of the sheet 15. When the hydraulic cylinder 19 is turned on, the frame 7 with the cart with the table 10 and the slag collector are lowered on it, and the sample 16 emerges from the hole in the sheet 15, the Drivem. 23, under the sheet 15, the cart 9 with the sample 16 rolls out along the guides 8 of the frame 7 from the zone of the rollers 2 of the roller table 1, then the sample 16 is removed from the table 10 by the interrupter 17 on the cart 18, which removes sample 16. for further processing weave, nalrimer, on the underground tone: nelyu in another span.

When cutting sample 16 through a T-shaped cutout 11, the sludge falls into the slag collector 14, and the combustion products (gases) are removed through the holes 12 in the walls of the table 10 by the ventilation boxes 24, while the rulers 13 prevent air from leaking and the area of the holes 12 It is selected taking into account the quantity of the formed combustion products and the power of the ventilation units.

Due to the fact that the removal of combustion products comes from a relatively small in volume chamber formed by the table 10 and the slag collector 14 while limiting the possibility of air leaks, the efficiency of ventilation with the same exhaust power is increased compared with the prototype.

The use of the proposed site eliminates manual labor during cutting and cleaning the sample due to the presence of a lifting frame with guides on which a cart with a table is placed. The removal of combustion products is ensured due to the presence of a T-shaped notch in the table top, where the combustion products (gases) are injected by pressure from a working gas-cutting tool, and holes in the wall of the table or char. which gases are removed by exhaust ventilation ducts.

The mentioned benefits improve the operating conditions of the site equipment. ,
