Description

Automatic shutter coil of strip clamp

Technical field

The utility model relates to a kind of coil of strip and hangs the improvement of getting clamp, and specifically a kind of automatic shutter coil of strip clamp is applicable to that hanging of medium-width strip volume get.

Background technology

At present, middle broadband band steel spreader adopts large-scale clamp mostly, comprise that jig arm, power folding blocking device and hanging apparatus constitute, the deficiency that this large-scale clamp exists is: complex structure, not easy to operate, cost is high, weight big (more than at least 5 tons), difficult in maintenance, and shipment need be used fork truck during clamp, waste time and energy, increase use cost.In addition, for general user, consumption is few, and the land used dispersion, and need with the wheeled crane lifting, and be not suitable for this moment lifting with large-scale clamp again, therefore, inapplicable general user.

Summary of the invention

The purpose of this utility model is to provide a kind of deficiency that overcomes the large-scale clamp of present use, and clamp is in light weight, simple in structure, stable performance, be convenient to make, use cost is low, convenient transportation, can directly be contained in the automatic shutter coil of strip clamp that uses on the crane, this automatic shutter coil of strip clamp, be not only applicable to the big user of consumption, and more be applicable to the general user that consumption is little.

For reaching above purpose, the technical scheme that the utility model adopted is: this automatic shutter coil of strip clamp, by a left side, right binding clip, a left side, right pincers handle, a left side, right torque arm, arm constitutes, left side binding clip is an one with right pincers handle, constitute " L " shape, right binding clip is an one with left side pincers handle, constitute oppositely " L " shape, a left side, right pincers handle is connected and fixed by the pincers axle, a left side, the upper end of right pincers handle and a left side, the lower end of right torque arm is respectively by corresponding bearing pin captive joint, a left side, the upper end of right torque arm is connected with the lower end of arm by same turning cylinder, suspension ring are also established in upper end at arm, it is characterized in that turning handle welding in the right torque arm, are provided with lock shaft on Zola's arm, pass through automatic shutter plate on the turning cylinder captive joint, the upside of automatic shutter integrated circuit board lock shaft on Zola's arm in the end of turning handle.The utility model is also implemented by following measure: described automatic shutter plate, by plate body, lock slots, pin shaft hole, oblique fan-shaped turning block constitutes, lock slots is located at the downside of plate body, the position of lock slots is with when the lock shaft on Zola's arm is stuck in the lock slots, can make a left side, distance between the right binding clip just in time snaps in the thickness of coil of strip and is advisable, oblique fan-shaped turning block is fixed on the plate body of lock slots upside by corresponding rotating shaft, the radius length of the outer edge of oblique fan-shaped turning block is consistent to the distance of plate body lower edge with corresponding rotating shaft, the radius length of the inside edge of oblique fan-shaped turning block equals the diameter sum of the lock shaft of corresponding rotating shaft to the distance of plate body lower edge and the Zola's arm, pin shaft hole is fixed by the handle that turns that penetrates in turning cylinder and the right torque arm, when hanging coil of strip work, suspension hook by crane hangs in the suspension ring of arm upper end, after slinging, with a left side, right binding clip is put on the coil of strip, a because left side, the locking distance of right binding clip with can snap in coil of strip in, be advisable in the outside, so, a binding clip is inserted in the coil of strip, another binding clip is on the coil of strip outer wall, a because left side, the action of gravity of right binding clip, continuing toward transferring a left side, during right binding clip, the upper edge of coil of strip just pushes a left side, the lower end of right pincers handle, a left side, just outwards open the upper end of right pincers handle, the handle that turns in the right torque arm just spurs the automatic shutter plate, make lock shaft skid off the lock slots of automatic shutter plate plate body downside laterally, simultaneously, oblique fan-shaped turning block rotates under the effect of self gravitation, the bottom surface of oblique fan-shaped turning block just is on the mouth of lock slots, at this moment, because the suspension hook of crane can stop to transfer, but the arm of hanging oneself again, a left side, right torque arm just spurs a left side, right pincers handle, the handle that turns in the right torque arm promotes the automatic shutter plate, lock shaft on Zola's arm is along sliding in the automatic shutter plate bottom side, during lock slots on sliding to the automatic shutter plate, because the effect that oblique fan-shaped turning block bottom surface stops, lock shaft can not enter lock slots, just continue along sliding in the automatic shutter plate, thereby make a left side, right binding clip is held coil of strip tightly, the coil of strip handling to the transfer car(buggy) after, transfer suspended wall, a left side, right torque arm is opened once more, make a left side, right binding clip opens, at this moment, lock shaft on Zola's arm is sliding outward, when sliding to the inside edge of oblique fan-shaped turning block, because its inside edge is longer, lock shaft just promotes oblique fan-shaped turning block and outwards rotates, leave the lock slots on the automatic shutter plate, when the lock shaft on Zola's arm snaps in the lock slots on the automatic shutter plate, a left side, right binding clip deployed position locking, at this moment, the left side of can slinging smoothly, right binding clip hangs next coil of strip again; Also establish fixing anti-skidding fixture block in the inboard of left binding clip, movable anti-skidding fixture block is fixed in inboard at right binding clip by bearing pin, on the clamping face of fixing anti-skidding fixture block and movable anti-skidding fixture block, be equipped with anti-skidding line, its effect: the one, the thickness of clamping coil of strip is finely tuned, the 2nd, increase the clamping friction force.

The beneficial effects of the utility model are: compare with the large-scale clamp of present use, need not to add in addition actuating unit, in the whole process that dress hangs, realize the automatic shutter of jaw fully by the mechanism performance of self, therefore, make structure optimization, reasonable, simple, easy to operate, and productive costs is low, usage charges are low, can increase work efficiency, not be only applicable to the big user of consumption, more be applicable to the general user that consumption is little.
