The specific embodiment

The utility model roll bending reversal hanger is to realize like this, the roll bending reversal hanger is to be made of rotation and clamp two parts, see Fig. 1, clamp part: clamping motor 1 and gear reducer 2 are assemblied in the fixed clamp 3, moving caliper 10 is sleeved on fixed clamp 3 outsides, by leading screw 4, screw 9 makes moving caliper 10 link to each other with fixed clamp 3, in the termination of leading screw 4 end cap 11 is set, fixed clamp slide block 6 and moving caliper slide block 8 are installed in respectively on fixed clamp 3 and the moving caliper 10, retracing spring 5 links to each other with moving caliper 10 with fixed clamp 3 and moving caliper slide block 8 with fixed clamp slide block 6, the pulling force of retracing spring 5 equals the weight of 1.2～1.4 times of slide blocks, is provided with three row's straight line needle rollers and forms linear roller bearing 7 between slide block and caliper; The opening that forms between moving caliper slide block 8 and the fixed clamp slide block 6 constitutes jaw.Fig. 1 is the situation of the perpendicular volume of clamp gripping, during operation jaw is inserted into the wall thickness of roll bending, and wherein fixed clamp slide block 6 is inserted in the hole of roll bending.Start clamping motor 1,, the jaw of clamp is dwindled by gear reducer 2, leading screw 4, screw 9 transmissions, the wall thickness of jaw contact and clamping roll bending, when gripping power reaches certain value, the electrical apparatus control system action, clamping motor 1 stops rapidly and brakes.This moment, clamp was initial gripping power to the gripping power of roll bending.When hanging perpendicular volume, because jaw is in the friction coefficient between roll bending much larger than slide block and the friction coefficient between caliper, hoisting crane is mentioned the roll bending reversal hanger, having under the condition of initial gripping power, friction force can make roll bending glide along fixed clamp 3 and moving caliper 10 together with fixed clamp slide block 6 and moving caliper slide block 8, because moving caliper 10 and fixed clamp 3 are formed a wedge shape down in the fastening of leading screw 4 and screw 9, increase along with the increase of sliding force to the downslide gripping power more, until roll bending is picked up.To be flipped finishing hangs the appointed place with roll bending, transfers the roll bending reversal hanger roll bending is landed, and under the combined action of the wedge shape counter-force of gripping power and retracing spring 5, clamp returns to initial position, and crawl clamping motor 1 is opened jaw, can unload clamp.

See Fig. 2, rotating part: counterweight 12, sprocket wheel 13, shackle 16, retarder 17 are installed on the bracing frame 15, output shaft on the retarder 17 is contained in the hole of sprocket wheel 13, can be relative to rotating with bracing frame 15, chain assemblies 14 is contained on the sprocket wheel 13, and be meshed with the nest eye of sprocket wheel 13, two end points below it and two end points of clamp are hinged.Should be definite like this on the clamp with two end points of chain assemblies 14 pivotallys attached, no matter be horizontal roll or perpendicular volume, must guarantee that all the center of gravity of clamp and roll bending is positioned at the centre of two chain assemblies 14 line of centers extended lines, and determine the position of clamp two-end-point according to mentioned above principle.

See Fig. 3, roll bending reversal hanger lifting horizontal roll figure, when hanging horizontal roll, after the horizontally mounted horizontal roll of grip finger, start clamping motor 1 and clamp roll bending, make jaw an initial gripping power be arranged, when hoisting crane is sling horizontal roll roll bending, the component owing to do not glide, this moment, roll bending and fixed clamp slide block 6, moving caliper slide block 8 did not glide; After roll bending rotation clamp began rotation, roll bending began to glide together with fixed clamp slide block 6 and moving caliper slide block 8, and approaching more perpendicular volume, and many more gripping powers that glide are big more.After hoisting crane is sling the roll bending reversal hanger of clamping roll bending roll bending is risen in the air, the output shaft on the retarder 17 drives sprocket wheel 13 and rotates, and an end of chain extends an end to be shortened, and the clamp below driving rotates together with roll bending.When just changeing then the roll bending reversal hanger make perpendicular volume be turned into horizontal roll, otherwise then for horizontal roll is turned into perpendicular volume, behind half-twist, press limit switch, limit switch moves, and makes retarder 17 stop clamp and stops the rotation.Unload clamp, clamp returns to original position under the combined action of the counter-force of wedge shape gripping power and retracing spring 5, opens clamp and unloads roll bending, and a handling rotary course finishes.
