Abstract

The utility model discloses a lifting tool for lifting a cylinder casting. The lifting tool comprises a lifting tool main body formed by assembling two lifting hooks in a crossing way. When in use, the lifting tool is lifted on a crane, the claw parts of the two lifting hooks of the lifting tool firmly grasp the lifted cylinder casting and are automatically locked by utilizing the principle of downward gravity in design, so that the heavier the casting is, the larger the self-locking force is, thereby avoiding the phenomenon of falling-off of the casting during lifting and ensuring the safety. The lifting tool has the advantages of simple manufacture, high safety factor, flexible and convenient operation, etc.

Description

A kind of suspender of handling cylinder block casting

Technical field

The utility model is fit to the handling to various cylinder block castings, belongs to the handling suspender.

Background technology

In the process of manufacture of cylinder block, the handling work of foundry goods is absolutely necessary, and at present, all adopts in the handling of cylinder block at curved one of reinforcing bar one end and colludes the handling of carrying out foundry goods.Its shortcoming is: foundry goods lacks foolproof in the handling process, is easy to generate and drops, and damages foundry goods, and has potential safety hazard.

Summary of the invention

The purpose of this utility model has been to provide a kind of safe foundry goods hoist tool, utilize the downward principle of gravity, success realizes the self-locking of foundry goods in the handling process, utilize the principle of work of pliers, in handling foundry goods process,, utilize the step in cylinder hole to hang with two cylinder holes of two pawl clamping foundry goods, by the self-locking that hits pay dirk of foundry goods self gravitation, thereby improve foundry goods at handling process safe coefficient.

Technical solution of the present utility model is such, comprises suspension hook, hinge pin, inhibiting device, iron chains, and particularly the suspension hook top connects iron chains, and there is hinge pin suspension hook and suspension hook pawl junction, between suspension hook handle and the handle inhibiting device are arranged.

Suspension hook is two hooks, and hook is that pliers is hook-shaped.

The utility model has the advantages that: attractive in appearance, generous, can the various serial cylinder blocks of handling, and on various article that other are fit to, make simple, safety factor is high, flexible operation, convenience etc.

Description of drawings

Fig. 1 is that the integral structure of the utility model suspender is installed assembly structure figure.

Fig. 2 is a suspension hook front view of the present utility model.

Fig. 3 is that cutaway view is looked on a suspension hook of the present utility model left side.

Among Fig. 1～Fig. 3: suspension hook (1), hinge pin (2), inhibiting device (3), iron chains (4).

The specific embodiment

Most preferred embodiment of the present utility model is such, further specifies this hanger structure and using method below in conjunction with accompanying drawing.With reference to accompanying drawing, suspension hook (1) is two scissors-like hooks, utilize the interface point between principle two hooks of pliers to have hinge pin (2) hinged, folder hands over the position that inhibiting device (3) is arranged between the handle of suspension hook (1) and the handle, suspension hook (1) top connects iron chains (4), and iron chains (4) is hung and tightly is linked on crane or the wall wall.During use, (1) two on the suspension hook of usefulness suspender, the suspension hook pawl is caught non-conterminous two the cylinder holes of cylinder block, uses crane lifting foundry goods.In the lifting process, the distance that the suspension hook pawl utilizes the gravity of self to dwindle two pawl till the clamping foundry goods, in the process that foundry goods is sling, is utilized the drop-down suspender of weight of foundry goods self, further forms a kind of self-locking device, guarantees the safety of handling process.

Claims (2)

1. the suspender of a handling cylinder block casting, comprise suspension hook, hinge pin, inhibiting device, iron chains, it is characterized in that suspension hook (1) top connects iron chains (4), there is hinge pin (2) suspension hook (1) and suspension hook pawl junction, and inhibiting device (3) is arranged between suspension hook (1) handle and the handle.

2. according to the suspender of the described a kind of handling cylinder block casting of claim 1, it is characterized in that suspension hook (1) is two hooks, hook is that pliers is hook-shaped.
