Description
Technical field
The present invention relates to underground job construction equipment field, specifically a kind of steel wire rope automatic tensioning tight knot for grab bucket
Structure.
Background technology
Impact Bucket Grab is during rigidity layer is rushed and dug, when moment on earth is dug in punching, screen resilience and moving system inertia because
Under the collective effect of element, steel wire rope often will produce slack and undisciplined and rebound phenomena, to make to be wrapped on reel originally suddenly
Remaining steel wire rope be subjected to displacement, loosen phenomenon, and in this way, when subsequent recovery steel wire rope, be easy for leading to steel wire rope
Arrange the generation of problem of misalignment.
Invention content
It is an object of the invention to overcome drawbacks described above, provide it is a kind of can avoid steel wire rope because grab bucket impact generate it is anti-
Elastic force and the automatic tension device of relaxation.
In order to achieve the above object, the invention is realized in this way：
A kind of steel wire rope automatic tension structure for grab bucket, including overhead traveling crane, the steel wire rope of traction grab bucket and fixed steel wire rope
One end of reel, steel wire rope is wound on reel, and the other end lifts grab bucket after bypassing day roof；Further include swelling device ontology,
The swelling device ontology is arranged on overhead traveling crane；The other end of steel wire rope bypasses the top of overhead traveling crane after swelling device ontology；It should
Swelling device is originally swing mechanism, when steel wire rope is led to steel wire rope looseness by the bounce that Impact Bucket Grab operation generates,
It is rotated by the rocking arm of swelling device to make steel wire rope keep tensioner state.
The described steel wire rope automatic tension structure for grab bucket, swelling device ontology include sliding bottom, compressed spring,
Rocking arm and wire rope guide wheel；Wherein, rocking arm center is rotatablely connected in sliding bottom, and compressed spring is arranged in the side of rocking arm, steel
Cord guide wheel is separately positioned on the both ends of rocking arm, and when steel wire penetrating swelling device is penetrated simultaneously at the top of a side guide wheel respectively
It is pierced by from the bottom of another side guide wheel；The top of compressed spring is located at the lower section of steel wire rope, when steel wire rope relaxes suddenly, compression
Spring jacks up and jacks up steel wire rope upwards simultaneously upwards.
The steel wire rope automatic tension structure for grab bucket, further includes spring base, nut and drawstring；Compressed spring is set
Upper spring seat is set on sliding bottom and covers, nut fixes drawstring with spring base and rocking arm respectively, in this way, spring base, compression
Spring and rocking arm form an elastics wing mechanism.
The present invention is by above-mentioned design, by the way that flexible swelling device ontology is arranged, has bullet by setting
Property swing swelling device ontology, in normal condition, the guide wheel in swelling device ontology is suppressed by steel wire rope, when steel wire rope because
For grab bucket impacting rebound power and moment become slack and undisciplined when, the spring base in swelling device ontology bounces to make to shake rapidly upward
Arm rotation is jacked up steel wire rope by guide wheel upwards, and such steel wire rope is still able to keep tensioner in the moment of impact grappling fixture landing
State, to avoid steel wire rope from generating wrong row's phenomenon on reel.
Description of the drawings
Fig. 1 is the standby mode schematic diagram of this Tensioning structure.
Fig. 2 is the working state schematic representation of this Tensioning structure.
Fig. 3 is the structural schematic diagram of swelling device ontology in this Tensioning structure.
Fig. 4 is the stereoscopic schematic diagram of this Tensioning structure.
Specific implementation mode
It is further illustrated the present invention below by way of specific embodiment.
As shown in Figure 1, Figure 2 and Figure 4, a kind of steel wire rope automatic tension structure for grab bucket, including overhead traveling crane 1, traction are grabbed
The reel of the steel wire rope 2 of bucket and fixed steel wire rope 2, one end of steel wire rope 2 are wound on rope drum, and the other end is around 1 top of overhead traveling crane
Lifting grab bucket afterwards；Further include swelling device ontology 3, which is arranged on overhead traveling crane 1；The other end of steel wire rope 2 is worn
Cross the top around overhead traveling crane 1 after swelling device ontology 3；The swelling device ontology 3 is elastics wing structure, when steel wire rope 2 by
Bounce that Impact Bucket Grab operation generates and when leading to steel wire rope looseness, rotated by the rocking arm 33 of swelling device to make steel wire rope
2 keep tensioner state.
As shown in figure 3, the steel wire rope automatic tension structure for grab bucket, swelling device ontology 3 includes sliding bottom
Seat 31, compressed spring 32, rocking arm 33 and wire rope guide wheel 34；Wherein, 33 center of rocking arm is rotatablely connected in sliding bottom 31, compression
Spring 32 is arranged in the side of rocking arm 33, and wire rope guide wheel 34 is separately positioned on the both ends of rocking arm 33, and steel wire rope 2 is filled across tensioner
It is to penetrate from the top of a side guide wheel 34 and be pierced by from the bottom of another side guide wheel 34 respectively when setting ontology；The top of compressed spring 32
Portion is located at the lower section of steel wire rope 2, and when the relaxation suddenly of steel wire rope 2, compressed spring 32 jacks up that rocking arm 33 is made to rotate upwards, therefore
Guide wheel 34 jacks up steel wire rope 2 upwards.
The steel wire rope automatic tension structure for grab bucket further includes spring base 35, nut 36 and drawstring 37, compression
Spring 32 is arranged on sliding bottom 31 and covers upper spring seat 35, and nut 36 consolidates drawstring 37 with spring base 35 and rocking arm 33 respectively
It is fixed, in this way, spring base 35, compressed spring 32 and rocking arm 33 form an elastics wing mechanism.
The present invention is by above-mentioned design, by swelling device ontology of the setting with elastics wing, in normal condition,
Guide wheel in swelling device ontology is suppressed by steel wire rope, when steel wire rope because grab bucket impacting rebound power and moment becomes slack and undisciplined
When, the spring base in swelling device ontology bounces that rocking arm rotation is made to jack up steel wire rope upwards by guide wheel rapidly upward,
Such steel wire rope is still able to keep tensioner state in the moment of impact grappling fixture landing, to avoid steel wire rope from being generated on reel
Mistake row's phenomenon.
