Formula.
The steel wire rope folding and unfolding course of work of the present apparatus：
Under locking state is original state, original state, the state of the reel 4-1 on stretcher 4 is：Stretcher stringing knot
When two reel 4-1 of structure are located at vertical position one on the other, the whirlpool spring 4-6 in the resistance rotation structure of stretcher 4 is in tensioning state,
Elastic deformation amount is located in bottom plate stopper slot 1-8 close to maximum, spacer pin 9, between total collection wire loop 8 and collection wire loop central shaft 11-7
Whirlpool spring 10 be in maximum distortion state, the spring between guide rod fixed seat 1-2 and the guide pad 7-2 of preloader base the 3rd
7-5 is in extended state, now tensioned on whole steel wire rope, and the tension force on steel wire rope is equal to the elastic force of whirlpool spring 10, less than steel
The maximum tension that cord is likely to occur；Steel wire rope is in the lock state under original state, and lock mode is prevented always by stopper slot
Collect the rotation of wire loop and then prevent the generation of unwrapping wire behavior, while the horizontal component that steel wire rope is produced by roll position is not enough to
Whirlpool spring 4-6 elastic force is overcome so that stringing structure rotates so that steel wire rope is in the state of " self-locking " with reel.
When hydraulic support, which is produced, moves frame behavior, through hydraulic support on the steel wire rope of straightness detection mechanism can be with shifting
Frame and there is the increased demand of rope length, because steel wire rope is in the lock state under original state, when rope length increase demand generation and
When actually locking due to steel wire rope without that can increase again, the tension force on rope can increase and increased impulsive force is larger so that steel
The horizontal direction component that cord is produced by reel 4-1 positions is more than resistance of the rotation stop plate 4-5 arc surfaces to reel, so as to
Drive the stringing structure of stretcher to be rotated around rotating shaft 4-3, and then cause stretcher stringing structure to be in new state：Stringing structure
Two reel 4-1 be located at same level, the steel wire rope on reel 4-1 now nearest apart from tension detector 3 to tension force
The distance of the line outlet of detector 2 is far smaller than the distance of the two under original state, so now steel wire rope is in instantaneous relaxation shape
Tension force is reduced on state, steel wire rope；Again because the lineoutofservice signal pull and the elastic force of whirlpool spring 10 that total collection wire loop 8 is subject under original state belong to
In opposing force, therefore when tension force is reduced on steel wire rope, the elastic force of whirlpool spring 10 can drive total collection wire loop 8 to reversely rotate, i.e., along pine
Line direction rotates, because the one sides reversely rotated along collection wire loop 8 of the stopper slot 1-8 on bottom plate 1-1 are in slope, therefore spacer pin master
Body bottom 9-3 hemisphere can the elastic force of whirlpool spring 10 effect under " cunning " go out stopper slot 1-8, while guide rod fixed seat 1-2 with
The guide pad 7-2 of base the 3rd spring 7-5 can pull preloader 7 to be moved to the direction away from stretcher 3, the lock of total collection wire loop 8
Determine state to be broken, and then the function of free unwrapping wire can be realized.
When rope capacity meet hydraulic support produce move frame displacement when required increased sufficient length when, now steel wire rope
Generally in relaxed state, when the rotation that the angular transducer on total collection wire loop 8 detects total collection wire loop 8 stops, this
When total collection wire loop 8 can be driven to rotate forward by controller controlled motor drive mechanism 11, because total collection wire loop 8 is located at preloader
On 7, preloader 8 can be moved along the 4th guide rod 1-3, and take-up is started so ought always collect wire loop 8 and be rotated around central shaft 11-7
When, total collection wire loop 8 is not only rotated, while always collection wire loop 8 can be moved along the 4th guide rod 1-3 to the direction of stretcher 4 until pacifying
Hemisphere mounted in the spacer pin bottom part body 9-3 of total collection wire loop 8 enters in stopper slot 1-8, so as to always collect the rotation meeting of wire loop 8
Stopped operating due to the spacing of spacer pin 9.After always collection wire loop 8 stops the rotation again, return motor 6 drives stringing structure
4-3 is rotated around the shaft, and the reel 4-1 for the plate 4-2 right-hand members that connect with the heart is slipped into rotation stop plate 4-5 arc structure again, i.e. stringing structure
Two reel 4-1 positions be changed into being located in vertical plane one on the other from being located in the same horizontal plane again, stretcher by
This completes secondary tensioning function.
Above-mentioned is exactly the take-up of the present apparatus and loose ends process；
Following process is total collection wire loop 8 for take-up and the processing method of unwrapping wire：
During take-up, motor-driven mechanism 11 drives total collection wire loop 8 to overcome between collection wire loop central shaft 11-7 and total collection wire loop 8
The acting rotation of whirlpool spring 10, now preloader 7 acted in the horizontal direction by spring 7-5 pulling force and steel wire rope tension, motor
Drive mechanism 11, which drives total dynamic collection wire loop 8 to rotate, can make it that the tension force on steel wire rope is increasing, when more than spring 7-5 pulling force
Afterwards, preloader 7 can drive total collection wire loop 8 to be moved along the 4th guide rod 1-3 to the direction of stretcher 4, and this process, which belongs to, to be overcome
Spring does work, so the tensile force on rope can gradually increase；Because the pilot hole of preloader 7 is matched somebody with somebody with the 4th guide rod 1-3 for gap
Close, so preloader 7 can overcome spring 7-5 pulling force to be moved to the direction of stretcher 4 under the traction of steel wire rope.When preloader 7
When driving total collection wire loop 8 to move near stopper slot 1-8, the spacer pin 9 on especially total collection wire loop enters after stopper slot 1-8,
Because stopper slot 1-8 plays position-limiting action to the rotation of spacer pin 9, therefore the total collection wire loop 8 being connected with spacer pin 9 also stops turning
It is dynamic；The tension force that now tensile force on steel wire rope is equal on the elastic force of whirlpool spring 10, steel wire rope has been able to reach certain numerical value,
Certain potential energy is accumulated on whirlpool spring 10 so that when motor-driven mechanism 11 is stopped, total collection wire loop 8 can be in steel wire simultaneously
The state of the lower holding geo-stationary of the elastic force effect of upper pulling force and whirlpool spring 10 of restricting, this process is referred to as pretension process.
During unwrapping wire, because stretcher 4 can first be acted under steel wire rope suddenly increased pulling force, the tensile force on steel wire rope
Can rapidly decline due to the action of stretcher, its reason be in two states before and after stretcher 4 reel 4-1 extreme higher positions with
The line outlet distance of tension detector 3 changes, and can increase rope capacity, and tension force declines；Due on the spring of whirlpool 10 drawing
Power is equal with the lineoutofservice signal pull before declining, therefore when steel wire rope upper pulling force declines, total collection wire loop 8 horizontal direction force is uneven,
Therefore total collection wire loop 8 can be reversely rotated under the drive of whirlpool spring 10, because stopper slot 1-8 domatic design can always to collect wire loop
Spacer pin 9 in 8 can only be inverted when being in stopper slot 1-8, therefore total collection wire loop 8 is reversely rotated under the drive of whirlpool spring 10, thrust
Pin 9 can whiz stopper slot 1-8.Simultaneously to remote under spring 7-5 pulling force effects of total collection wire loop 8 on the 4th guide rod 1-3
The direction motion of tight device 4, domatic design can equally cause thrust pin 9 to be easier to leave from stopper slot 1-8；Leave after stopper slot
1-8 total its rotary motion of collection wire loop 8 is under no restraint, therefore can discharge length of steel rope according to the demand of hydraulic moving stand
Degree.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
