Abstract

The utility model relates to an overturning connecting rod mechanism provided with a safe locking device, which can be applied to molten steel transportation operation of a steel plant, aiming at solving the problem that a connecting rod mechanism under a steel teeming ladle easily falls off from an ear base. The utility model provides the overturning connecting rod mechanism provided with the safe locking device, the connecting rod mechanism is arranged under the steel teeming ladle, the upper end of the connecting rod mechanism is hung on the ear base of the steel teeming ladle, a hole is penetrated on the connecting rod mechanism just under the ear base, and the hole is internally provided with the locking device. The overturning connecting rod mechanism solves the problem of safety accidents caused by the connecting rod mechanism which drops off in suspension transportation of an empty tank, thus having simple and reliable structure and convenient use, fully ensuring the connecting rod mechanism not to automatically exit from a pin hole, greatly improving the using safety and being beneficial to popularization and application.

Description

The linkage of tumbling of band safe locking device

Technical field:

The utility model is used for the molten steel hauling operation of steel mill, is specifically related to a kind of linkage of tumbling.

Background technology:

In the production operation of steelshop, the key equipment of its molten steel accumulating all adopts ladle 1.For remaining slag in the bucket is removed, need by crane auxiliary hook 5 it to be carried out 180 ° and tumble by the bag linkage that turns over that is provided with at the bottom of the bucket.The linkage of tumbling that extensively adopts is rod hinge connection form (as shown in Figure 1) at present, the B point is the hinge that floats among the figure, it act as and turns over folding and it being hung on the ear seat 2 of jar arm 4, turn over plucking, hanging by crane auxiliary hook 5 and finish of jar arm, its maximum characteristics are to need not ground staff's operation to link up with.

But there is a potential safety hazard in this mechanism, promptly when ladle (slack tank) when the allocation and transportation process descends (this moment auxiliary hook not on the suspension hook gudgeon 3) if below unsteady hinge B place, collide other object, the inertia force that the ladle deadweight produces in owing to descend with because of collision an external force that makes progress of turning over jar arm 4 and being subjected to is constituted a pair of action and reaction power, under the effect of this power, turn over jar arm 4 and will move up and break away from ear seat 2 and landing, and whole linkage (pull bar 6, turn over jar arm 4) the nearly 3m of length of run, quality reaches 1t, and, will cause serious consequence to personnel and equipment with fixedly hinge A revolution.

The utility model content:

At the linkage of the present ladle below problem of landing from the ear seat easily, the utility model provides a kind of linkage of tumbling that can strengthen safety coefficient greatly.

Described purpose is achieved by the following scheme:

A kind of linkage of tumbling with safe locking device, described linkage is installed in the below of ladle, and the upper end of described linkage is suspended on the ear seat of ladle, bores a hole on the linkage under the ear seat, and locking device is set in the hole.

Described locking device comprises bearing pin, is fixed with two on the described bearing pin and avoids its position block of deviating from the hole, and the location link stopper is welded on the bearing pin by spring catch, is fixed with handle in the termination of described bearing pin.

Being shaped as of the hole of being worn on the described linkage, contacting an end with handle is elongated hole, is used for passing through for position block; The other end is a circular port, is used for the supply and marketing axle and passes through.

The utility model has solved the problem that causes security incident in the slack tank handling because of the linkage landing, described simple and reliable for structure, easy to use, guaranteed that fully linkage can not withdraw from pin-and-hole automatically, improved the security of using greatly, therefore be beneficial to and apply.

Wherein, fixing hinge A, the hinge B that floats, ladle 1, ear seat 2, suspension hook gudgeon 3 turns over jar arm 4, hole 4-1, crane auxiliary hook 5, locking device D, pull bar 6, bearing pin 7, handle 8, position block 9, spring catch 10.

The specific embodiment:

Elaborate the utility model preferred embodiment below in conjunction with accompanying drawing.

The described linkage of tumbling of present embodiment is installed in the below of ladle, with reference to Fig. 2, Fig. 3, linkage is by being articulated in the pull bar 6 that B orders and turning over jar arm 4 and form, one end of pull bar 6 is hinged on the bottom of ladle 1, turn over jar arm 4 the upper end be suspended on the ear seat 2 of ladle 1, the innovative point of this patent is, deviate from from ear seat 2 for fear of turning over jar arm 4, at the 4-1 that bores a hole on jar arm 4 that turns under the ear seat, locking device D is set in the 4-1 of hole, can not deviate from the ear seat even can guarantee like this to turn over when jar arm 4 moves on the external force because of meeting yet, thereby improve safety in utilization.

With reference to Fig. 4-Fig. 7, the structure of locking device D comprises bearing pin 7, bearing pin 7 is passed in the hole 4-1 that turns over jar arm 4, like this, runs into when moving on the external force when turning over jar arm 4, and bearing pin 7 promptly can be blocked by ear seat 2, deviates from the ear seat thereby avoid turning over jar arm 4.The termination of bearing pin 7 is fixed with handle 8, installs with convenient.Be fixed with position block 9 on bearing pin 7, position block 9 is two, is used to limit bearing pin 7 in the lateral attitude of turning on jar arm 4, and purpose is to avoid bearing pin 7 to drop out in the hole.In order to increase the bonding strength between position block 9 and the bearing pin 7, the location link stopper can be welded on the bearing pin 7 by spring catch 10.

Aforementioned locking device penetrates in the hole of linkage for convenience, the shaped design that linkage can be bored a hole is, contacting an end with handle is elongated hole, the other end is a circular port, and the long axis direction of elongated hole should be level, when using, only need with this device aim at elongated hole direction insert put in place after again dextrorotation turn 90 degrees and get final product.

Present embodiment is the protection domain that the exemplary illustration of this patent is not limited it; those skilled in the art can also carry out the part to it and change; the short of spiritual essence that exceeds this patent all is considered as the replacement that is equal to this patent, all within the protection domain of this patent.
