The utility model discloses a universal clamp device used as a suspending and unloading tool for square metal compacts. The utility model is characterized in that a switching shaft (3) travels through an awl disk (9); a balance ring (8) and a switching base (4) are connected with a suspending rod (2) and a suspending ring (1); a clamp claw (13) is connected with a pin shaft (15) and a clamp base (7) by a link plate (16); a link rod (10) is connected with the clamp base (7) by a pin shaft (11); a pin shaft (12) is fixed on the link rod (10); a switching pin (5) is arranged in a pin hole of the switching base (4); a pressure ring (6), the switching base (4) and the clamp base (7) are fixed together by screw bolts and screw nuts after the pressure ring (6) is sheathed. The utility model has compact structure and no direction, and only needs one person. The utility model can automatically complete suspending and unloading at high temperature and at normal temperature.

Description

Universal clamp device

The utility model be a kind of be used for the square metal base hang the instrument of unloading automatically.It belongs to metallurgical industry and hangs and unload technical field.

At present, the instrument of unloading that hangs that China hangs in the field of unloading in metallurgical industry has several, hangs the instrument of unloading directivity is arranged but all exist, and hanging the scene of unloading need have artificial adjustment direction, labour intensity is big, work situation is abominable, and fatal accident and complex structure easily take place, bulky, operate loaded down with trivial detailsly, efficient is low, the cost height.

The purpose of this utility model just provides a kind of above-mentioned existing problems that overcome, and is simple in structure, volume is little, easy to operate, safe and reliable, efficient is high, the universal caliper unit that cost is low.

The utility model is achieved in that specifically by suspension ring (1), suspension rod (2), opens and closes axle (3), opens and closes seat (4), opens and closes pin (5), pressure ring (6), pincers seat (7), balance ring (8), awl dish (9), gangbar (10), bearing pin (11,12,15), a chela (13), alloy is inserted (14) and connecting panel parts such as (16) are formed.

Switching axle (3) passes awl dish (9), balance ring (8), switching seat (4) and suspension rod (2), suspension ring (1) and links together.Alloy is inserted (14) welding-on on chela (13).Chela (13) links together with pincers seats (17) by connecting panel (16) and bearing pin (15), gangbar (10) is connected the pin-and-hole interior cover upper press ring (6) that clamps seat (7) seat (4) and with bolt, nut pressure ring (6), switching seat (4) and pincers (7) is fixed together with bearing pin (11), promptly form a universal clamp of integral body.

The whole universal clamp of the utility model is a circular tower shape, and pincers seat (7) circumference evenly has the individual chela position-limited trough of odd number (as: 7,9,11,13,15) (groove is several to be decided according to the size of universal clamp specification).A chela (13) is arranged in each position-limited trough, open and close five of seat (4) circumference uniform distributions and open and close pin (5), open and close axle (3) and divide upper and lower two sections, the lower surface of upper end and hypomere the upper surface all have the zig-zag enclosed slot, opening and closing axle (a 3) hypomere has five axially to open and close grooves.Opening and closing groove can slide along opening and closing pin (5).Open and close every upper and lower the reciprocatingly sliding once of axle (3), under the effect that opens and closes pin (5), open and close axle (3) and rotate 36 ° automatically.When switching pin (5) is in switching position, groove a place (Fig. 2), open and close axle (3), a balance ring (8), awl dish (9) and all locate upper/lower positions, gangbar (10) round end portion down rotates at the action of gravity lower edge of balance ring (8) bearing pin (11), bearing pin (12) on the gangbar (10) promptly forces chela (13) outwards to open, fall chela this moment to metal base, pincers seats (a 7) chela (13) on every side just has three to be equicrural triangle and to fall in the metal base both sides, all the other chelas no longer are subjected to the control of bearing pin (12) by metal base jack-up.When crane affects suspension ring (1), suspension rod (2), opens and closes when moving on axle (3), the awl dish (9), opening and closing pin (5) is in switching groove b place (Fig. 2) elongated slot, no longer work, gangbar (10) round end portion is rotated down around bearing pin (11) under the effect of awl dish (9), bearing pin (12) on the gangbar (10) promptly forces three chelas to draw in inwards, metal base is clamped sling.When slinging again after the metal base of slinging falls again, open and close pin (5) and be in the position, a place (Fig. 2) that opens and closes groove again, all chelas are all got back to whole open virgin states again, finish the one-period operation.

Fig. 1 is the utility model scheme drawing.

Fig. 2 opens and closes axle (3) to go up switching groove expansion scheme drawing.

Advantage of the present utility model:

1. universal clamp is a circular tower shape, and uniform multijaw around the clamp block is non-directional, arbitrarily clamp is dropped on the metal base, ensures three chelas and is isosceles triangle base is clamped, and unloading is rapid, the efficient height. And the clamp of at present domestic all uses has directionality, and need are manually adjusted direction during clamping, labour intensity is big, and environment is abominable, and personal injury easily takes place.

2. universal clamp has adopted the automatic shutter form, falls and can clamp for the first time, falls and can unclamp for the second time, and the crane workman is simple to operate, and unloading is rapid. And at present, the clamp of domestic use divides unloading system, clamping system and release system, needs compound operation, complicated operation, and efficient is low, easily meets accident.

3. this universal clamp is reasonable in design, compact conformation, and volume is little, and main parts size all adopts the high-quality steel and through respective handling, suspension clamp is firm, safe and reliable, long service life.

4. this universal grip finger welding-on has the heat-resistance abrasion-resistance alloy piece, often wet all capable of hoisting the unloading of high humidity, and comformability is strong and wide.And the magnetic force that uses at present hangs and unloads the unsuitable high-temperature operation of device.

5. this universal clamp has become series of products, and is complete in specifications, good manufacturability.70% parts can be convenient to maintenance by exchanging, and manufacturing cost and use cost is low.
