Embodiment
Be described further below technical scheme, but claimed scope be not limited to it is described.
As shown in Figure 1,2,3, 4, a kind of adaptive pull rope mechanism, including bolt 1, pressing plate 2, spring 3, push rod 4, guide way
5th, pressing plate 2 is fixed on the top of push rod 4 by fixed seat 6 and wedge joint 9, bolt 1；Guide way 5 is hollow circular cylinder, bottom
Outside disc-shaped extension, outside are wrapped up by spring 3；Guide way 5 is fixed in fixed seat 6, and push rod 4 passes through guide way 5 and wedge shape
Joint 9 is connected；Spring 3 is compression spring, and one end is peaked on pressing plate 2, and the other end peaks at the bottom of guide way 5；Wedge joint 9
On be fixed with steel wire rope 91.
Also include baffle plate 92, roller reversal valve 8, check valve 10 and Winch motor 11, baffle plate 92 is fixed on wedge joint 9
On, roller reversal valve 8 is arranged in fixed seat 6, there is reversing valve core 81 on roller reversal valve 8, and baffle plate 92 can be with wedge joint 9
Motion triggers reversing valve core 81.
Roller reversal valve 8 is normally closed type two-position three way magnetic valve, and the interface 3 of roller reversal valve 8 connects Winch motor 11
Positive oil circuit, check valve 10 is provided with interface 2, hydraulic oil only flows out from interface 2, and interface 1 connects hydraulic oil tank, capstan winch horse
The reverse oil circuit of 11 reached is connected to hydraulic oil tank by the port of export of check valve 10.Normally closed type two-position three way magnetic valve is powered
When, interface 2 leads to interface 1, and interface 3 is closed, and now, hydraulic oil forward direction enters Winch motor 11, and Winch motor 11 rotates forward；Power-off
When, interface 2 is closed, and interface 1 leads to interface 3, and hydraulic oil is back to interface 1 by interface 3, do not entered in Winch motor 11, is twisted
Table motor is stopped.When hydraulic oil is redirected back into, due to the blocking effect of check valve 10, hydraulic oil is directly entered capstan winch horse
Reach, drive its reversion to realize and receive steel wire rope.
Also include locating shaft 7, locating shaft 7 connects as one wedge joint 9 and push rod 4.
The both sides of fixed seat 6 are provided with guide slot 61 along pushrod movement direction, and locating shaft 7 is arranged in guide slot 61.It is fixed to set
To groove 61, wedge joint 9 can be made to be moved along predetermined direction, prevented in motion process because vibrations and shake of machinery etc.
Factor is tightened up steel wire rope 91 to it and had an impact, and effectively prevents the generation of security incident.
Length of the length of the guide slot 61 less than spring 3 when non-loaded.
The length of the guide slot 61 is more than length when spring 3 is in most compressed state.The length of guide slot 61 should
It is long between it can produce the distance of effective push in spring 3, the motion of wedge joint 9 can be caused long, no spring 3
Still there is the possibility of motion during active force, the safety of engineering machinery is impacted；It is too short such as setting, then it can make spring 3
Not up to extreme position when just limit the motion of wedge joint 9, reduce the effective length of adaptive tense wire rope 91, influence just
Normal Engineering Task.
Roller reversal valve 8 is installed in fixed seat 6 with the direction of motion of the baffle plate 92 along push rod 4, fortune of the baffle plate 92 along push rod 4
During dynamic direction motion, reversing valve core 81 can be triggered.Reversing valve core 81 can not be triggered when moving to extreme position such as baffle plate 92, then
The rotation for stopping Winch motor 11 can be led to not, now, spring 3 is in extreme position, pressing plate 2 can not be produced and pushed away
Power, continue the retractable operation of steel wire rope 91, disorder cable phenomenon easily occurs and causes the safety of engineering machinery to receive and has a strong impact on.
Length of the distance of baffle plate 92 and reversing valve core 81 less than spring 3 when non-loaded, maximum compression is in more than spring 3
Length during state.When wedge joint 9 is moved, the distance of baffle plate 92 and reversing valve core 81 should be such that spring 3 locates all the time
In impaction state, and spring 3, not when having thrust to pressing plate 2, baffle plate 92 should trigger reversing valve core 81, whole so as to ensure
Mechanism is in the state of stop motion, prevents the generation of disorder cable phenomenon.
During work, spring 3 is lifted by push pressing plate 2 to push rod 4, and a upward power is provided for wedge joint 9,
Because steel wire rope 91 is fixed in wedge joint 9, so pretightning force is provided for steel wire rope 91, once pine occurs for steel wire rope 91
Dynamic, in the presence of this pretightning force, steel wire rope 91 is moving upward, and steel wire rope gap caused by because of loosening eliminates, it is therefore prevented that
The appearance of disorder cable, meanwhile, wedge joint 9 drives baffle plate 92 to move, when the limit tension position of spring 3 is reached, gear
Plate 92 touches the reversing valve core 81 on roller reversal valve 8, changes the flowing of hydraulic oil, Winch motor 11 is stopped, prevent
It is unexpected to occur.In addition, by reverse delivery hydraulic pressure oil, control Winch motor 11 is inverted, it is possible to achieve steel wire rope 91 is packed up
Action.
The present invention makes steel wire rope attach pretightning force at any time at work, kept away by way of setting spring on guide way
Exempted from because steel wire rope pretightning force deficiency and caused by disorder cable phenomenon, greatly promote the operating efficiency of engineering machinery, extend steel
The service life of cord, and by setting maximum pretension distance, can prevent from unexpectedly occurring, add the peace of engineering machinery
Quan Xing.In addition, mechanism of the present invention is relatively simple, can be used in enterprising exercise of a variety of engineering machinery using steel wire rope, using model
Enclose wide.
