Description
Technical field
The utility model belongs to large-scale backhoe ship raising equipment technology field, more particularly to a kind of large-scale backhoe ship steel stake
The fixing device of hoist rope head.
Background technology
Steel wire rope can be caused in the stress concentration at fag end position by being presently used for the common pressure head method of steel wire rope tail end fixation,
When steel wire rope bears excessive load, it is easy to produce failure damage at fag end position.
In practical engineering application, the problem of stress concentration of steel wire rope head never has good solution, usually makees
Method be the steel wire rope for selecting more high standard to reduce the harm of steel wire rope head stress concentration, cause a series of problems, such as of high cost.
The content of the invention
The utility model provides a kind of large-scale backhoe ship steel stake raising to solve technical problem present in known technology
The fixing device of steel wire rope head.
The purpose of this utility model be to provide it is a kind of have it is simple in structure, it is cheap, be used for big load work in steel wire rope
Condition is in use, the pulling force of fag end fixing end can be significantly reduced, the large-scale backhoe ship steel stake raising steel for the features such as reducing use cost
The fixing device of cord head.
The fixing device scheme of the utility model is mainly the reel devised for lay winding wire ropes, and the reel is by both sides
Side plate supports, and to prevent the steel wire rope on reel from slack rope occurs, pressing plate is set on side plate.Steel wire rope is wound necessarily on reel
After the number of turns (3~5 circle), fag end end is fixed at otic placode.
The characteristics of steel wire rope head fixing device of the utility model meaning, is to wind on reel by steel wire rope certain
The number of turns (3~5 circle) significantly reduces the pulling force of fag end fixing end, reduces the influence that fag end stress concentration integrally uses steel wire rope,
Under identical stress, the steel wire rope with changing higher intensity can be not required to without considering fag end stress concentration.
The fixing device of the large-scale backhoe ship steel stake hoist rope head of the utility model is adopted the technical scheme that：
A kind of fixing device of large-scale backhoe ship steel stake hoist rope head, its main feature is that：Large-scale backhoe ship steel stake raising
The fixing device of steel wire rope head includes rope drum and otic placode, and rope drum is made of intermediate winding drum, side plate supported on both sides, and otic placode is used for
End is fixed after steel wire rope is wound in intermediate winding drum.
The fixing device of the large-scale backhoe ship steel stake hoist rope head of the utility model can also take following technical measures：
The fixing device of the large-scale backhoe ship steel stake hoist rope head, its main feature is that：In the support side plate of reel
Pressing plate is provided with, for preventing from being wrapped in the steel wire rope looseness in intermediate winding drum.
The fixing device of the large-scale backhoe ship steel stake hoist rope head, its main feature is that：Otic placode is equipped with fixing axle, uses
End is fixed by fixing axle after steel wire rope winds 3~5 circles in intermediate winding drum.
The utility model has the advantages and positive effects of：
The fixing device of large-scale backhoe ship steel stake hoist rope head is as a result of the brand-new technical side of the utility model
Case, compared with prior art, the utility model have the advantages that simple in structure, cheap, are used for big load work in steel wire rope
For condition in use, the pulling force for significantly reducing fag end fixing end significant can be reduced, reduction steel wire rope head stress concentration is overall to steel wire rope
The influence used, under identical operating mode, without considering steel wire rope head stress concentration, can not need to change the steel wire rope of higher specification, reduce
Use cost.

Embodiment
For that can further appreciate that the utility model content of the utility model, feature and effect, the following examples are hereby given, and
Attached drawing is coordinated to describe in detail as follows：
Refering to attached drawing 1.
Embodiment 1
A kind of fixing device of large-scale backhoe ship steel stake hoist rope head, including rope drum and otic placode, rope drum is in
Between reel 1, side plate supported on both sides 2 form, otic placode 3 is equipped with fixing axle, after winding 3~5 circles in intermediate winding drum 1 for steel wire rope
End is fixed by fixing axle.
Pressing plate 4 is provided with the support side plate 2 of reel, for the steel wire rope looseness for preventing from being wrapped in intermediate winding drum 1.
The present embodiment specific implementation process：
The present embodiment is used for the fixing device of large-scale backhoe ship steel stake hoist rope head, and primary structure includes intermediate winding drum
1st, both sides roll support side plate 2, steel wire rope head fix otic placode 3, steel wire rope pressing plate 4.Specific implementation process：
After load cable winds 3~5 circles in intermediate winding drum 1, steel wire rope head is fixed at otic placode 3, to prevent reel
On steel wire rope there is slack rope situation, set pressing plate 4 that the steel wire rope on reel is fixed in support side plate 2.
The present embodiment is simple with the structure, cheap to wait good effect.It is used for big load operating mode in steel wire rope
In use, the pulling force of fag end fixing end can be significantly reduced, reduce the influence that steel wire rope head stress concentration integrally uses steel wire rope,
Under identical operating mode, the steel wire rope of higher specification without considering steel wire rope head stress concentration, can not be needed to change, reduces use cost.
