Outside ", " side " etc. is only direction and position with reference to annexed drawings.Therefore, the direction and position term used is to illustrate
And understand the present invention, rather than to limit the present invention.
Embodiment:
As depicted in figs. 1 and 2, the present invention provides a kind of anti-over-discharge devices of bridge crane wirerope, including wirerope
Reel 1, the inner wrap of the cable drum 1 has several circle wirerope 2, and is provided in the underface of cable drum 1
One end of driving box 3, the wirerope 2 is fixed on cable drum 1, and the other end is along the vertical cutting of cable drum 1
Line freely hangs down, and the driving box 3 is internally provided with left-handed axis 4 and dextrorotation axis 5, and in the vertical side of 3 front surface of driving box
To several rectangular apertures 6 are provided with, rectangular aperture 6 plays the role of limit, the left-handed axis 4 and the vertical placement of dextrorotation axis 5,
And left-handed axis 4 and dextrorotation axis 5 being equidistant to 3 front surface of driving box, the top of the left-handed axis 4 are connected with the first driving electricity
Machine 7 drives left-handed axis 4 to turn left, and the surface of left-handed axis 4 is provided with several left-handed bars 8, and the left-handed bar 8 passes through square
Shape opening 6 stretches out driving box 3, and left-handed bar 8 is respectively positioned on wirerope 2 and hangs down the right side of part, the top connection of the dextrorotation axis 5
There is the second driving motor 9, driving dextrorotation axis 5 turns right, and the surface of dextrorotation axis 5 is provided with several dextrorotation bars 10, described
Dextrorotation bar 10 stretches out driving box 3 by rectangular aperture 6, and dextrorotation bar 10 is respectively positioned on wirerope 2 and hangs down the left side of part.
As depicted in figs. 1 and 2, the left-handed bar 8 and dextrorotation bar 10 are respectively perpendicular to left-handed axis 4 and dextrorotation axis 5, and left-handed
Bar 8 and dextrorotation bar 10 are arranged alternately in the vertical direction, so that left-handed bar 8 and dextrorotation bar 10 hang down part perpendicular to wirerope 2,
And prevent left-handed bar 8 and dextrorotation bar 10 from touching mutually when rotating, while the direction of 2 pulling force of wirerope being enable more frequently to change
Become, improve stop effect, the left-handed bar 8 is respectively positioned on same perpendicular, and the dextrorotation bar 10 is respectively positioned on same vertical flat
On face, and the distance between 10 place perpendicular of dextrorotation bar and left-handed 8 place perpendicular of bar are straight slightly larger than wirerope 2
Diameter, so that left-handed bar 8 and dextrorotation bar 10 will not interfere the tenesmus of wirerope 2, the left-handed bar 8 and adjacent dextrorotation bar 10 when initial
Between vertical distance be equal so that the direction of 2 pulling force of wirerope uniformly changes, prevent wirerope 2 because of sudden change pulling force
And damage, the left-handed bar 8 and dextrorotation bar 10 are equal in length, and left-handed bar 8 and dextrorotation bar 10 stretch out the length of driving box 3
Equal to twice that 2 vertical portion of wirerope assigns to 3 distance of driving box, so that wirerope 2 is located in left-handed bar 8 and dextrorotation bar 10
Between, when preventing left-handed bar 8 and dextrorotation bar 10 from rotating, wirerope 2 is detached from, the left-handed bar 8 to 6 left end of rectangular aperture it is horizontal away from
From horizontal distance of the dextrorotation bar 10 to 6 right end of rectangular aperture is equal to, so that the maximum angle phase that left-handed bar 8 and dextrorotation bar 10 rotate
Together, the top of the left-handed bar 8 and dextrorotation bar 10 is provided with barrier plate 11, and wirerope 2 is prevented to be detached from left-handed bar 8 and dextrorotation bar
10, the width of the rectangular aperture 6 is slightly larger than the diameter of left-handed bar 8 and dextrorotation bar 10, and the length of rectangular aperture 6 is equal to left-handed
Axis 4, dextrorotation axis 5 arrive twice of 3 front surface distance of driving box, enable left-handed bar 8 and dextrorotation bar 10 without hindrance in rectangle
Rotation in opening 6, and the maximum angle that left-handed bar 8 and dextrorotation bar 10 rotate prevents left-handed bar 8 and dextrorotation bar close to 45 degree
10 encounter dextrorotation axis 5 and left-handed axis 4.
As shown in Figure 1 to Figure 3, which makes when cable drum 1 is due to inertia over-discharge wirerope 2, the first driving
Motor 7 drives left-handed axis 4 to turn left, and the second driving motor 9 driving dextrorotation axis 5 turns right, and makes left-handed axis 4 and dextrorotation axis 5
On left-handed bar 8 and dextrorotation bar 10 rotate respectively while to the left and to the right, intersect pull wirerope 2 fold to the left and to the right, directly
The both ends of rectangular aperture 6 are encountered respectively to left-handed bar 8 and dextrorotation bar 10 and are stopped, so that the wirerope 2 of over-discharge will not be to tenesmus
Fall so that cargo do not exceed it is pre- put range, simultaneously because the means of stop wirerope 2 do not force prevent, repeatedly change
The direction for becoming 2 pulling force of wirerope enables the steady soft stopping tenesmus of wirerope 2, makes wirerope 2 will not be due to larger friction
Damage, improves the service life of wirerope 2.
In conclusion the main characteristic of the invention lies in that:
(1) present invention is by being arranged driving box in the underface of cable drum, the left-handed axis of setting and dextrorotation in driving box
Axis, and several left-handed bars and several dextrorotation bars are respectively set on left-handed axis and dextrorotation axis, left-handed bar is respectively positioned on wirerope and hangs down
Partial right side, dextrorotation bar is respectively positioned on wirerope and hangs down the left side of part, so that when cable drum is due to inertia over-discharge steel wire
When rope, left-handed bar and dextrorotation bar rotate respectively while to the left and to the right, and wirerope is pulled to fold to the left and to the right, so that over-discharge
Wirerope will not fall downwards, so that cargo does not exceed and pre- puts range.
(2) present invention pulls wirerope by the way that several left-handed bars and several dextrorotation bars are arranged to the left and to the right respectively, so that
The means of stop wirerope do not force to prevent, and the direction of lineoutofservice signal pull is varied multiple times, and keep wirerope steady soft
The stopping of sum drops, and damage wirerope will not because of larger friction, improves the service life of wirerope.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
Benefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claims
