Abstract
The utility model discloses a lazy arm nose structure of a crane. The lazy arm nose structure comprises a lazy arm, wherein a seamless tube is arranged at the middle position of the head of the lazy arm; a beam channel is welded on the outer circumferential surface of the seamless tube; one end of the beam channel is welded at the head of the lazy arm while the other end of the beam channel is welded on the outer circumferential surface of the seamless tube; a sealing plate is arranged at the end part of the seamless tube; flat steel is welded inside the sealing plate; an ocular plate is welded outside the sealing plate; a mounting hole is formed in the ocular plate. The problem that a lazy arm of a crane of a wire rope luffing ship is unstably horizontally arranged and fixed in a non-working state, and greatly shakes in severe weathers such as strong wind and big waves so as to affect the safety of the ship and people is effectively avoided by the action of the seamless tube at the middle position of the head of the lazy arm. A lazy arm nose can be completely put into a shelf, and the ocular plate can be connected and fixed with the shelf, so that the stability and the safety of the overall lazy arm are greatly improved, and the shaking of the lazy arm in bad weather conditions such as strong wind and big waves can be alleviated to the maximal extent.
Description
Technical field
The utility model relates to weight-lifting equipment technical field, especially arm nose structure for crane.
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.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides arm nose structure for a kind of crane rational in infrastructure, 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:
Arm nose structure for a kind of crane, comprise arm, described arm head midway location is provided with seamless tube, on the outer circumference surface of described seamless tube, is welded with channel-section steel, one end of described channel-section steel is welded on arm head position, and the other end of described channel-section steel is welded on the outer circumference surface of seamless tube; The end that is positioned at seamless tube is provided with shrouding, and the internal welding of described shrouding is connected to band steel, and the outside weldings eye plate of described shrouding, has mounting hole on described eye plate.
Further improvement as technique scheme:
Described seamless tube is welded in arm head midway location;
The diameter of described shrouding is identical with the diameter of seamless tube.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, reasonable, easy for installation, by the effect of seamless tube is installed at arm head midway location, effectively avoided 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.Arm nose can be put into shelf completely, and eye plate can be connected and fixed with shelf, and the stability of whole arm, safety are strengthened greatly, has farthest reduced arm and has rocked under the inclement weather environment such as wind and waves.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Wherein: 1, arm; 2, seamless tube; 3, channel-section steel; 4, band steel; 5, shrouding; 6, eye plate; 7, mounting hole.
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, arm nose structure for the crane of the present embodiment, comprise arm 1, arm 1 head midway location is provided with seamless tube 2, on the outer circumference surface of seamless tube 2, be welded with channel-section steel 3, one end of channel-section steel 3 is welded on arm 1 head position, and the other end of channel-section steel 3 is welded on the outer circumference surface of seamless tube 2; The end that is positioned at seamless tube 2 is provided with shrouding 5, and the internal welding of shrouding 5 is connected to band steel 4, and the outside weldings eye plate 6 of shrouding 5, has mounting hole 7 on eye plate 6.
The diameter of shrouding 5 is identical with the diameter of seamless tube 2.
The design of the utility model channel-section steel 3, for strengthening fixedly seamless tube 2.
The design of the utility model shrouding 5, for dustproof and fixedly eye plate 6 effects.
The design of the utility model band steel 4, stressed for strengthening eye plate 6.
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.
