Abstract
A jib shelf structure for a crane includes a lower shelf; the top of the lower shelf is equipped with an upper shelf through a connecting sleeve; the top of the upper shelf is equipped with a tiger's mouth in an arc structure; a jib nose is placed inside the tiger's mouth; one side of the upper shelf is welded with a connecting plate; and the connecting plate is fixed to one end of a lock through a bolt end and the other side of the lock is locked with an eye plate of the jib nose through a key. As the usual role of the design of the jib shelf, the jib nose can be placed completely into the jib shelf, and the eye plate of the jib nose can be connected and fixed with the jib shelf through the key and the lock, so that the stability and security of the whole jib are greatly improved, and the shaking of the jib in strong wind, big waves and other harsh weather conditions is reduced by the maximum.
Description
Technical field
The present invention relates to weight-lifting equipment technical field, especially crane arm rack structure.
Background technology
Deck crane, is a kind of large deck machinery 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, when 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 fixedly arm when shelving fixedly 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.
Summary of the invention
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 solution adopted in the present invention 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 locks by the eye plate of key and arm nose.
Further improvement as technique scheme:
On described lower shelf welding and 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.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, reasonable, easy for installation, conventionally the effect of design arm shelf, can effectively solve the arm of rope luffing crane for ship when 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.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
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 invention 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 locks by key 2 and the eye plate of arm nose 1.
On lower shelf 10 welding and ship deck.
On lower shelf 10, be welded with reinforced rib 11.
On lower shelf 10, interval is provided with step plate 12.Thereby to locking 5 positions, open and lock being connected of arm shelf and arm nose 1 for personnel climbing;
Rubber pad 3 is high oil resistant, resistant material.Rubber pad 3 plays the effect of buffering, damping.
The present invention uses reliably, working stability.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
