The whole suspension arm is high in stability and safety.

Description

Crane arm rack structure

Technical field

The utility model relates to weight-lifting equipment technical field, especially crane arm rack structure.

Background technology

Deck crane, is the large deck machinery of one on ship, and it is a kind of equipment of ship loading and unloading goods.

Deck crane of the prior art, rope luffing crane for ship, its arm, in the time of off working state, needs level to shelve, to guarantee that arm can significantly not rock when the wind and waves; Conventionally it is upper end position in dichotomous arm that the arm adopting is shelved, can not completely stable fixing arm in the time shelving fixing arm, particularly running under the inclement weather conditions such as wind and waves, arm rocks obvious,, there is potential safety hazard in the safety that has a strong impact on boats and ships and personnel.

Utility model content

The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of crane rational in infrastructure arm rack structure, thereby improves the stability that arm is shelved under off working state, and safety is good.

The technical scheme that the utility model adopts is as follows:

A kind of crane arm rack structure, comprise lower shelf, the top of described lower shelf is provided with upper shelf by adapter sleeve, the top of described upper shelf is provided with the tiger's jaw of arc-shaped structure, in described tiger's jaw, place arm nose, a side that is positioned at shelf is also welded with connecting panel, is bolted lock one end on described connecting panel, and the other end of described lock is by the eye plate locking of key and arm nose.

Further improvement as technique scheme:

Described lower shelf is welded on ship deck;

On described lower shelf, be welded with reinforced rib;

On described lower shelf, interval is provided with step plate;

Described lower shelf and upper shelf all adopt solid drawn pipe;

Described rubber pad is high oil resistant, resistant material.

The beneficial effects of the utility model are as follows:

The utility model compact conformation, reasonable, easy for installation, conventionally the effect of design arm shelf, can effectively solve the arm of rope luffing crane for ship in the time of off working state, level is shelved fixing unstable, under the inclement weathers such as wind and waves, produce and rock more greatly, affect a difficult problem for boats and ships and personal security and problem that the arm nose that designs need to coordinate with it.Because arm nose can be put into arm shelf completely, and the eye plate of arm nose can be connected and fixed by key, lock and arm shelf, stability, the safety of whole arm are strengthened greatly, farthest reduced arm and rocked under the inclement weather environment such as wind and waves.

Fig. 2 is the right elevation of Fig. 1.

Wherein: 1, arm nose; 2, key; 3, rubber pad; 4, tiger's jaw; 5, lock; 6, bolt; 7, connecting panel; 8, upper shelf; 9, adapter sleeve; 10, lower shelf; 11, reinforced rib; 12, step plate.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As depicted in figs. 1 and 2, the crane of the present embodiment arm rack structure, comprise lower shelf 10, the top of lower shelf 10 is provided with upper shelf 8 by adapter sleeve 9, the top of upper shelf 8 is provided with the tiger's jaw 4 of arc-shaped structure, the interior placement arm of tiger's jaw 4 nose 1, and a side that is positioned at shelf 8 is also welded with connecting panel 7, on connecting panel 7, by bolt 6 fixing lock 5 one end, the other end of lock 5 is the eye plate locking with arm nose 1 by key 2.

Lower shelf 10 is welded on ship deck.

On lower shelf 10, be welded with reinforced rib 11.

On lower shelf 10, interval is provided with step plate 12.Thereby open and lock being connected of arm shelf and arm nose 1 for personnel climbing to locking 5 positions;

Lower shelf 10 and upper shelf 8 all adopt solid drawn pipe.

Arm nose 1 is arranged on tiger's jaw 4 by rubber pad 3, and rubber pad 3 is high oil resistant, resistant material.Rubber pad 3 plays the effect of buffering, damping.

The utility model uses reliable, working stability.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
