Abstract

The utility model relates to a six-claw clamping crane, which comprises a threaded hanging post, a lower connecting disc, an upper connecting disc and a plurality of claw bars, wherein the top of the threaded hanging post is provided with a hanging hook, the claw bars are uniformly distributed around the upper connecting disc and the lower connecting disc, the lower ends of the claw bars are provided with outwards extending parts, the lower connecting disc is dynamically positioned at the lower end part of the hanging post, the upper connecting disc is matched with the threaded section of the hanging post through screw threads, the upper end parts of the claw bars are hinged on the upper connecting disc, the middle parts of the claw bars are hinged with a support rod, and the other end of the support rod is hinged on the lower connecting disc. In the operation, the opening and closing action of the claw bars uniformly distributed around the hanging post can be realized only through rotating the hanging post, the claw bars are reasonably supported on the tire ring steel wire arranged at a tire blank opening through the outwards extending parts arranged at the lower ends of the claw bars, and the rubber part stress in other positions is avoided. The six-claw clamping crane has the characteristics of reasonable structure, ingenious design, uniform stress distribution, light weight and flexibility and is simple to operate, when a large-scale tire blank with the weight being 3t is hung, the deformation quantity is very little, the operation can be completed only in 10 minutes, and the quality and the efficiency of the production process can be effectively ensured through the use of the clamping crane.

Description

A kind of six pawl cards hang

Technical field:

The utility model relates to a kind of six pawl cards of using in order to lifting tyre rim steel ring and hangs.

Background technology:

Tire production process needs mobile frequently tire base to different station, finishes corresponding operation.For giant tire, often to finish moving of tire by mechanical equipment, hang and grab lack of standardization or deflection, very easily cause mass defects such as the distortion of tire semifinished product mouth, starved.How a kind of special-purpose hanging device is provided, promptly becomes the object of the utility model research.

Summary of the invention:

But the purpose of this utility model is uniform and six pawl cards synchronous on-off of a kind of a plurality of claw bar radials of design hangs.

Technical solutions of the utility model are achieved in that a kind of six pawl cards hang, and it is characterized in that comprising screw thread davit, following the binding dish and the last binding dish of a top band suspension hook and are distributed on the claw bar that upper and lower binding dish complex root lower end on every side has the outreach part; Following binding dish dynamicpositioning is in the davit bottom, and last binding dish cooperates with davit thread segment spiral; The claw bar upper end is hinged on the binding dish, the middle part is hinged with a strut bar, and the other end of this strut bar is hinged on down on the binding dish.During operation, only need the rotation davit, be evenly distributed on its claw bar on every side and can realize opening and closing movement, the outreach part of mat claw bar lower end rationally is supported on the steel bead wire of tire semifinished product mouth, avoids other rubber position, position stressed.

Described davit top is fixed with an operation board, handled easily, and more laborsaving.

Described outreach part is an inclination sole that is welded on the claw bar bottom, and this inclination pin outer end is an arc structure, closes with tire semifinished product tone, reduces the stressed deflection of tire base.

The utlity model has rational in infrastructure, design ingenious, stressedly is evenly distributed, simple to operate, light and handy flexible characteristic, rotate by davit, realize claw bar folding degree scalable, can accurate and effective catch the steel bead wire position in fetus rim of the mouth, and can make things convenient for rapidly and unload; The claw bar outreach part becomes arc structure, and is suitable with tire semifinished product mouth radian, effectively avoids taking place because of stressed rim of the mouth out-of-round phenomenon; Weigh 3 tons large-scale fetus of lifting, deflection is few, only needs 10 fens clock times to finish, and the use that this card hangs can effectively guarantee the quality and the efficient of production process.

Description of drawings:

Below in conjunction with concrete legend the utility model is described further:

The 43-arc structure

The specific embodiment:

See figures.1.and.2, six pawl cards hang, and it comprises davit 1, last binding dish 2, following binding dish 3 and claw bar 4; Davit 1 top has a suspension hook 11, top is fixed with an operation board 12, and davit 1 outside face has thread segment 13; Last binding is coiled 2 spirals and is engaged on this thread segment 11, and binding is coiled 3 dynamicpositioning in the davit bottom down; 4 one-tenth of complex root claw bars be evenly distributed on upper and lower

binding dish

2,3 around, claw bar 4 upper ends are hinged on the binding dish 2, the middle part is hinged with a strut bar 41, the other end of this strut bar 41 is hinged on down on the binding dish 3.During operation, rotary manipulation dish 12, under the driving of davit thread segment 13, last binding dish 2 can produce dipping and heaving; If it descends, claw bar 4 can drive complex root claw bar 4 and outwards open synchronously under the cooperation of strut bar 41; If 2 upward movements are coiled in last binding, under strut bar 41 tractions, claw bar 4 closes synchronously.

Described claw bar 4 lower ends have an outreach part 42, and this outreach part 42 is for being welded on an inclination sole of claw bar 4 bottoms, and this inclination pin outer end is an arc structure 43, avoids damaging steel bead wire.

Claims

1. a pawl card hangs, and it is characterized in that comprising screw thread davit, following the binding dish and the last binding dish of a top band suspension hook and is distributed on the claw bar that upper and lower binding dish complex root lower end on every side has the outreach part; Following binding dish dynamicpositioning is in the davit bottom, and last binding dish cooperates with davit thread segment spiral; The claw bar upper end is hinged on the binding dish, the middle part is hinged with a strut bar, and the other end of this strut bar is hinged on down on the binding dish.
