Pattern description

The subject of the utility model is the track rail of a mining floor-mounted railway, especially a heavy-duty and heavy-duty mining floor rack railway. In mining, standard U-sections or I-sections with a height of 180 mm, especially for racked racks, which, due to the installed power of the rails and their weight, are often reinforced with transverse or at least sectional longitudinal ribs, as utility model PL - W.114592, giving the rail tracks the character of a box-like structure in the cross-section. Such reinforcement of the railroads is technically defective due to the long welds influencing the shape of the railroad, and it is expensive and it is difficult to use trims to prevent the railroad from falling off the railroad if the floor is uneven.

The conducted tests and observations allowed to determine the optimal shape of the running rail, ensuring the correct and failure-free operation of the queue due to the railway track.

The running rail according to the pattern of the mining floor rail is a standard height I-section, the width of the transverse flanges, the thickness of the web and the thickness of the transverse flanges are a function of the height, so the width of the shelves is 0.75-0.85 of the height of the rail, preferably 0.77, the thickness of the web and the thickness of the shelves is 0.075-0.09 for the height of the rail, preferably 0.088 for the thickness of the web and 0.079 for the thickness of the shelves.

Such a shape of the rail ensures optimal rail strength in mining conditions without the need for reinforcements and allows for collision-free use of chucks.

The track rail in the pattern of the mining floor railway is shown in the cross-section in the attached drawing.

The running rail of the mining floor railway is a section with a cross-section I-section, and the individual sections interconnected form a two-track railway track, while the I-section rail with a height H has a width S of shelves 1 equal to S = (0.75-0.85) 1- 1, and the web 2 and the flanges 1, respectively, have the thicknesses G and F measured at a distance of 1/4 of the width S of the flaps 1 equal to G, F = (0.075-0.09) H, preferably S = 0.77H, G = 0.088H and F = 0.079H.
