Abstract

The utility model belongs to the field of hoisting machinery and is especially suitable for hoisting and transporting multi-specification steel flat blanks. The utility model mainly solves the problem of quick hoisting of the multi-specification steel flat blanks. The utility model comprises a hanging-hoisting part, a hoisting arm part, a loose hoisting self-locking part, and a hook foot size-adjustable movable part, wherein, the loose hoisting self-locking part is composed of a coupling plate hinge 13, a coupling plate hand ring 14 and a positioning plate 15; the hook foot size-adjustable movable part is composed of a connecting sleeve 5, a fixing pin 3 and a reinforcing bolt 6. The utility model has the advantages of simple structure, low cost, and convenient operation. The utility model is suitable for the continuous production operation of the frequent change of the specification of the hoisted steel flat blanks.

Description

Fast Adjustable S. A. plate slab hoisting pincers

The utility model belongs to the lifting machine field, is specially adapted to many gauge steel of handling slab.

At present, the normally used hoisting pincers of handling plate slab hangs the partial sum arm by extension partly to be formed, and hangs the hanging part branch and comprises big ring, chain and unload clasp that arm comprises cross bar hook pin, cross bar axle, cross bar yoke plate.Its length of boom is fixed, and cross bar and hook pin are connected as a single entity, and the clamp size is non-adjustable.When the handling plate slab, be suspended on the suspension hook of crane encircling greatly, with artificial method cross bar hook pin drawn back and clamp plate slab, suspension hook rises, utilize lever principle to clamp plate slab and transport to the desired position, again with manually cross bar hook pin being unclamped handling, the put procedure of finishing the handling plate slab.This method handling efficient is low, speed is slow, dimensions is single, can not realize the rhythm of production of continuous high speed, and it be unable to do without manual operations, and safety factor is low, causes easily and falls.

The purpose of this utility model is to be to provide a kind of adjustable plate slab hoisting pincers of S. A. that the plate slab specification is frequently changed in handling that adapts to.

The purpose of this utility model is achieved in that

Fast Adjustable S. A. plate slab hoisting pincers, it comprises that original extension hangs partial sum arm part, hang the hanging part and divide by unloading clasp, chain and big ring and form, arm partly comprise by cross bar axle, cross bar yoke plate, cross bar hook pin, left and right hook pin and on bracelet form; By the cross bar axle, cross bar and cross bar yoke plate form hinge shape, it comprises that also pine hangs the active part of self-locking partial sum hook pin size adjustable, pine hangs from latching segment to be made up of yoke plate hinge, yoke plate bracelet and locating plate, the yoke plate bracelet is fixed on the yoke plate hinge, and locating plate is fixed on the cross bar, and the active part of hook pin size adjustable is made up of adapter sleeve, fixator pins and strengthening stud, adjustment hole is arranged on the adapter sleeve, and adapter sleeve is fixed on the cross bar by strengthening stud; In the left and right insertion adapter sleeve, with the adjustment hole internal fixation in the fixator pins insertion adapter sleeve, several adjustment holes are arranged on the adapter sleeve, look the length variations of handling and set several specifications, hook pin size is by the decision of plate slab thickness, and the combination of arm, adapter sleeve, hook pin can be changed to the plier groups of various sizes; Yoke plate hinge head has crotch, can hook locating plate;

The utility model has increased size adjustment function and self-locking property, realize that by the crane man operation automatic pine hangs, need not increase new engine installation, make lifting job efficient, safe and reliable, simple in structure, cost is low, easy to operate, be applicable to the frequent continuity production operation of the higher and blank specification of frequency transposing.

Below in conjunction with drawings and Examples the utility model is described further:

Fig. 1 is a structural representation of the present utility model;

Structural representation when Fig. 2 is the separation of the utility model hook pin;

As shown in the figure, the hook heads on the yoke plate hinge 13 is hooked locating plate 15, and clamp keeps open configuration.When hanging thing clamp is placed on the handling blank portable yoke plate bracelet 14 and makes yoke plate hinge 13 throw off locatings plate 15, the crane lifting, chain 11 rises, and cross bar 9 rises simultaneously, and by cross bar axle 7, cross bar 9 and cross bar yoke plate 8 are hinged to pincer.Left and right hook pin 1 becomes to making the hook pin tightly to embrace blank toward interior contraction.Blank hangs and is placed into position side following time, and chain 11 unclamps, and cross bar 9 lies in and hangs on the thing, and left and right hook pin 1 unclamps, and the steel plate blank also leaves the unhook gap.When chain 11 rises once more is that the hook heads of yoke plate hinge 13 is hooked locating plate 15, and this moment, clamp recovered open configuration, realizes automatic loose metal action.
