Description

Self-opening internal-supporting lifting appliance

The technical field is as follows:

the utility model relates to a machining hoist specifically is related to the hoist of a processing thick short type tubular workpiece, especially is suitable for in the merry go round machine, immediately crouches the heavy tubulose part of machining center loading and unloading and remove the self-opening internal stay hoist of this type of work piece relevant.

Background art:

in machining, especially in workpieces machined by vertical lathes and vertical and horizontal machining centers, when large-hole rotary workpieces exist, the workpiece is loaded and unloaded, the workpiece is troublesome, a person who can move manually carries the workpiece, and a sling is used for the workpiece, so that the labor intensity of workers is high, and serious potential safety hazards exist.

The invention content is as follows:

the utility model aims to overcome above-mentioned shortcoming, provide a self-opening internal stay hoist, it can be steady safe promptly the work piece easily, remove the place that needs placed, reduce intensity of labour, avoided the injury to operating personnel.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the self-expanding internal-supporting lifting appliance comprises a lifting ring, an upper hinge joint, a hinged plate, a movable claw and a movable support which are matched with each other; the top of the upper hinge joint is fixed on the lifting ring, the bottom of the upper hinge joint is connected with one end of each of the hinge plates, the other end of each of the hinge plates is hinged with the upper end of each of the movable claws, the movable claws are hinged on the movable support, and the bottom of each movable claw is provided with an outward clamping jaw.

Furthermore, the number of the hinged plates is three, each group of the two hinged plates is three, one end of each group of the two hinged plates is hinged with the bottom of the upper hinged joint, the other end of each group of the two hinged plates is hinged with the upper end of the corresponding hinged claw, and the upper end of each hinged claw is clamped between the two hinged plates.

Furthermore, the hanging ring and the upper hinged joint are locked and fixed through welding or bolts.

Furthermore, the hinged parts are hinged by hinge pins to ensure flexible rotation.

Adopt above-mentioned technical scheme, the utility model is suitable for a work piece has the short heavy tube dish class part of through-hole and relative symmetry, and its innovation part just lies in relying on gravity and need not other auxiliary fixtures, just can reach reliable safe work piece of grabbing, and the operation is very simple nimble, seems simple, but its effectual industry difficult problem of having solved.

Description of the drawings:

the accompanying drawings, which are described herein, serve to provide a further understanding of the invention and constitute a part of this specification, and the exemplary embodiments and descriptions thereof are provided for explaining the invention without unduly limiting it. In the drawings:

FIG. 1 is a schematic perspective view of the present invention;

FIG. 2 is a schematic plan view of the present invention;

fig. 3 is a schematic structural diagram of the state of holding the workpiece according to the present invention.

The specific implementation mode is as follows:

in order to make the technical problem, technical solution and advantageous effects to be solved by the present invention clearer and more obvious, the following description of the present invention with reference to the accompanying drawings and embodiments is provided for further details. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1-3, for the embodiment of the present invention, the self-expanding internal-supporting hanger of the present invention utilizes the lever principle of the mechanism, including a hanging ring 1, an upper hinge joint 2, a hinged plate 3, a movable claw 4, a movable support 5, and a hinge pin 6; the upper part of the upper hinge joint 2 is fixed on the hanging ring 1, the bottom of the upper hinge joint 2 is respectively connected with one end of three groups of 3 hinge plates 3, the other end of the three groups of hinge plates 3 are respectively hinged with the upper ends of three movable claws 4, finally the three movable claws 4 are respectively hinged on the movable support 5, and all hinged parts are hinged by 8mm hinge pins 6, so that the rotation flexibility is ensured.

When the lifting appliance is operated and used, as long as the crane hook hooks the lifting ring 1, the whole lifting appliance is in a natural drooping and opening state, the movable claw 4 at the position of the movable support 5 can be slightly held by a hand to enable the movable claw 4 to be contracted to a size state of an inner hole of a workpiece 7 to be lifted, the movable claw 4 penetrates through the inner hole of the part, the movable claw 4 can be naturally opened after the hand is released, the claw 41 at the lower end of the movable claw 4 grasps the edge or the groove of the inner hole at the bottom of the workpiece 7, the upper end of the movable claw 4 and the hinged plate 3 are in a contracted state under the action of gravity of the workpiece and the self, and the workpiece is always clamped under the action of the lever, as shown.

The lifting appliance is suitable for short, short and heavy pipe disc type parts with through holes on workpieces, has the innovation point that the workpieces can be reliably and safely gripped only by means of gravity without other auxiliary accessories, and is very simple and flexible to operate.

While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood that the invention is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
