Detailed Description
As shown in fig. 1-4, a structure for preventing a steel wire rope of a movable pulley of a large-scale hoisting device from disengaging from a groove comprises a bracket 1, wherein the bracket 1 is of an arc-shaped structure, and one side surface of a concave surface of the bracket 1 is in sliding fit with the outer surface of the movable pulley 2; the bracket 1 is connected with the shield 4 by an adjusting bolt 3.
Preferably, the bracket 1 can be broken from the middle by a seamless steel pipe and bent into a shape fitting the outline of the pulley; the length of the steel wire rope is slightly larger than the half circumference of the movable pulley 2, and when the steel wire rope 7 falls too much, the steel wire rope 7 can be supported to prevent groove falling.
Preferably, the concave side of the bracket 1 is of an inward-bent arc-shaped groove 11 structure, and the arc-shaped groove 11 is in contact fit with the arc surface of the movable pulley 2.
Preferably, the outer surface of the bracket 1 is provided with three through holes which are distributed at intervals of 90 degrees; the outer surfaces of the through holes are connected with M20 hexagon nuts as bracket nuts 51.
Preferably, the shield 4 is a hollow cylindrical structure; the outer surface of the shield 4 is provided with three through holes which are distributed at intervals of 90 degrees; the outer surfaces of the through holes are connected with 20 hexagon nuts serving as shield nuts 52; the bracket nut 51 on the surface of the bracket 1 is connected with the shield nut 52 on the surface of the shield 4 through the M20X 60 adjusting bolt 3.
Preferably, the shield 4 is sleeved outside the movable pulley 2 and the bracket 1; the outer surface of the shield 4 is provided with a plurality of threading holes 6 with the aperture of 20mm, and the steel wire rope 7 which rounds the outer surface of the movable pulley 2 passes through the threading holes 6.
