RU99114935A - TUBULAR CONVEYOR WITH HANGING TAPE - Google Patents

Claims (3)

1. A tubular conveyor with a hanging tape, including a support frame (stand) with closed guides fixed on both sides of the conveyor, made in the form of single pipes and enveloping the drive and end drums, and an endless conveyor belt, on the sides of which roller suspensions are evenly fixed with the possibility of their movement along the guides, characterized in that at the places of folding of the tape into the pipe of its side from the side of the working surface they are closed to each other and bent towards the side to ensure reliable closure eyes belt surface with a radius of curvature defined by the relation:

where r is the radius of the limb of the sides of the tape, m;
E _n - the elastic modulus of the tape, MPa;
t is the thickness of the tape, m;
G _-1 - the endurance of the tape, MPa. 2. A tubular conveyor with a hanging tape according to claim 1, characterized in that in the places of rolling the tape into the pipe, the radius of curvature is determined by the ratio:

where R is the radius of the conveyor pipe, m;
In - the width of the tape, m;
r is the radius of the bend of the tape, m;
π is a transcendental number equal to 3.141;
α is the angle defining the radius of the bend of the tape, rad;
L _n - the width of the zone of overlap of the sides of the tape, m 3. A tubular conveyor with a hanging tape according to claims 1 and 2, characterized in that in the places where the tape is rolled into a pipe, the distance between the tube guides is determined by the ratio:
L _on = 2 (R + A) • sinβ,
where L _on is the distance between the axial lines of the guides, m;
A is the distance from the lining on the tape at the place of attachment of the roller suspension to the axial line of the tubular guide, m;
β is the angle defining the distance between the axial lines of the tubular guides, degrees.
