The utility model discloses a solve the technical scheme that above-mentioned technical problem adopted and be: the outer sides of two stock rails of the automatic rerailing device of the mine car are fixed together with two guide rails through gap irons, the inner sides of the stock rails are fixed together with a rhombic rail through the gap irons, a rhombic rail-aiding rerailing layer made of round steel is welded on the rail surface of the rhombic rail in a distributed mode, the rail surface of the rhombic rail-aiding rerailing layer is 20mm higher than the rail surface of the stock rails and the rail surface of the guide rails, the whole rerailing device is arranged at the position of about 20m straight rails on the bottom of each station shunting turnout of a 600mm gauge inclined roadway rail, and the low end of the rerailing device faces the direction of coming cars of the.

The utility model has the advantages that: due to the adoption of the novel automatic re-rail technical design, the defects of long time, low efficiency and insufficient safety guarantee for manually processing the upper track of the mine car are effectively overcome, the automatic re-rail of the derailed vehicle is realized when the derailed vehicle runs to the re-rail device, the consumption of re-rail materials is reduced, the labor intensity of workers is reduced to a certain extent, the personal safety is ensured, the re-rail time is shortened, and the transportation efficiency is greatly improved.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows:

as shown in figure 1, the outer sides of two stock rails 1 of the automatic rerailing device of the mine car are fixed with two guide rails 2 through gap irons 3, the inner sides of the stock rails 1 are fixed with diamond-shaped rails 4 through the gap irons 3, diamond-shaped rail-side rerailing layers 5 made of round steel are distributed and welded on the rail surfaces of the diamond-shaped rails 4, the rail surfaces of the diamond-shaped rail-side rerailing layers 5 are 20mm higher than the rail surfaces of the stock rails 1 and the rail surfaces of the guide rails 2, the whole rerailing device is arranged at the upper part of a 20m straight track of each yard bottom branch turnout of a 600mm gauge inclined roadway track, and the lower end of the rerailing device faces the direction of coming of.

As shown in figure 1, two stock rails 1 of the automatic rerailing device of the mine car are made of steel rails and are arranged in a bilateral symmetry mode to guide the inner wheel of the derailed mine car to lift and rerail, and the distance between the stock rails and a diamond-shaped rail 4 in the middle is kept to be 50 mm.

As shown in figure 1, two guide rails 2 of the automatic rerailing device of the mine car are made of steel rails and are arranged in a bilateral symmetry mode, the upper end and the lower end of each guide rail 2 are bent outwards to form an included angle of 13-15 degrees with a stock rail 1, the direction of wheels of the mine car is limited, and the wheels and the stock rail 1 are kept at a distance of 50mm from each other.

As shown in figure 1, the gap iron 3 of the automatic rerailing device of the mine car is made of steel plates and is arranged in a bilateral symmetry mode, the left stock rail 1, the right stock rail 2 and the diamond-shaped rail 4 are fixed together through bolts to form a rail groove for guiding the inner wheel of the derailing mine car to transversely move and reraile, and the distance between the lateral stock rail 1, the guide rail 2 and the diamond-shaped rail 4 is kept to be 50 mm.
