Detailed Description

As shown in fig. 1 to 4, the lifting gripper comprises a connecting portion 1, and two ends of the connecting portion 1 are respectively provided with a gripping portion 2.

In the specific implementation, the connecting part 1 on the clamping claw is connected to the lifting device through a steel rope. And when carrying out slab or steel sheet and shifting, establish earlier the cover with clamping part 2 on the slab that is located the upper strata, then connecting portion 1 upward movement under overhead hoist's drive to at the in-process of motion, clamping part 2 accomplishes and carries out the centre gripping to slab both sides and upper and lower wall and fix, until shift the slab to corresponding position department, overhead hoist places the slab and places the department at slab placement, and place the centre gripping of back clamping part 2 unclamping the slab when the slab.

The connecting portion 1 comprises a connecting middle plate 11, a connecting seat 10 is arranged at the upper end of the connecting middle plate 11, and the connecting seat 10 is convenient for the steel cable on the lifting device to be connected and fixed.

Clamping part 2 includes a pair of diaphragm 20, be located inboard diaphragm 20 and install in connecting middle plate 11, be equipped with well piece 22 between the diaphragm 20, be equipped with limit shaft 21 between the diaphragm 20 both ends, a plurality of spring pins 23 have been worn on well piece 22, the upper end of spring pin 23 all overlaps and is equipped with spring 24, the lower extreme of spring pin 23 is equipped with fly leaf 25, the both sides of fly leaf 25 all are equipped with curb plate 26, be equipped with square post between the both ends of curb plate 26, all overlap on the limit shaft 21 and be equipped with centre gripping rectangular plate 27, the spacing hole 28 of slant has all been seted up on centre gripping rectangular plate 27 upper portion, the upper end in the spacing hole 28 of slant extends to the outside slope, horizontal rectangular hole 29 has all been seted up to the lower part of centre gripping rectangular plate 27, limit shaft 21 all wears in the spacing hole 28 of slant, square post all wears horizontal rectangular hole 29, centre gripping rectangular plate 27 downwardly extending ground is equipped with downwardly extending arm 31, the lower welt 32 is equipped with perpendicularly inwardly extending ground to the lower extreme of downwardly extending arm 31. The lower liner plate 32 is wedge-shaped, and the inner side thereof is a small end. The side plate 26 is provided with two rotating projections 33 extending upward at both ends, the rotating projections 33 at the same end are hinged with a lower push-down inclined plate 35, the inner wall of the lower part of the clamping rectangular plate 27 is provided with a push arm 30, and the inner end of the push arm 30 acts on the lower push-down inclined plate 35, so that the lower end of the lower push-down inclined plate 35 acts on the steel plate. Spring pieces 34 are mounted on the back side of the lower inclined push plate 35, middle baffles 36 are mounted on the spring pieces 34, and the middle baffles 36 are arranged between the side plates 26.

When slab clamping transfer is carried out, an operator firstly sets each lower liner plate 32 between two slabs, then the lifting device drives the clamping part 2 to move upwards, and when the lower liner plate moves upwards, the connecting middle plate 11 drives the transverse plate 20 to move upwards, when the transverse plate 20 moves upwards, the side shaft 21 acts on the inclined limiting hole 28, so that the clamping rectangular plate 27 moves inwards along the horizontal rectangular hole 29, the clamping rectangular plate 27 moves inwards, the lower liner plate 32 penetrates through a gap between the slabs until the inner wall of the lower extension arm 31 acts on the side wall of the slab, when the clamping rectangular plate 27 moves inwards, the inner side end of the pushing arm 30 acts on the lower inclined plate 35, so that the lower inclined plate 35 rotates downwards around a hinged point until the lower end of the lower inclined plate 35 acts on the upper side of the slab, paired clamping is completed at the moment, and then lifting transfer operation of the slab is carried out.

The spring plate 34 is arranged to tilt upward when the transfer is completed and the push-down sloping plate 35 loses the acting force of the push-up arm 30, so that the slab can be clamped and transferred again conveniently.

Wherein, the setting of spring 24, when shifting the completion back, when the gripper jaw loses ascending pulling force, spring 24 will make curb plate 26 downstream to will drive centre gripping rectangular plate 27 downstream when curb plate 26 downstream, and when centre gripping rectangular plate 27 downstream, will make centre gripping rectangular plate 27 keep away from each other under the direction of the spacing hole 28 of slant, and finally realize cancelling the centre gripping of slab.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and it is obvious that those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
