Description
Technical field
The invention belongs to hydraulic engineering gate lift technique field, it is related to a kind of dropproof locking device of grasping beam and locking side
Method.
Background technique
Power station travelling hoist is used to lift by crane the gate or trash rack of porous mouth, to avoid frequently assembling and disassembling sunpender, one
As be equipped with auto clawing beam.Weight hook type grasping beam is to be grabbed on small-sized gate or trash rack using a kind of more machine automatization
Beam, weight hook type grasping beam adjust the position of weight by operator to realize that it is de- that itself and gate (trash rack) are grabbed.
It mentions in front of the door, grasping beam is to separate with gate, at this time in dam facing, manually moves weight to right side, is in suspension hook and hangs down
Straight state, when auto clawing beam, which is transferred to, to be abutted against with the pin shaft on gate, the outer rim arc surface of suspension hook slips over the pin of gate lifting eye
Axis, suspension hook inclination continue to fall to suspension hook hook end, slip over pin shaft, suspension hook is returned to plumbness again and tangles gate.
When Xiamen, grasping beam tangles gate, and weight is pulled to left side, there is suspension hook in becoming to intermediate, inclined state
Gesture after gate is sling at this time, since the huge weight of gate presses suspension hook, causes suspension hook that cannot work as lock toward intermediate, inclined
Door is transferred to after ground sill, and suspension hook sheds load and just voluntarily deviates from outward.
After unhook process when from its Xiamen is it is found that gate transfers to ground sill, suspension hook is just voluntarily deviate from.If gate card
In gate slot, suspension hook also can voluntarily be deviate from, and gate plays pendulum at this time, may continue traveling downwardly again and fall gate slot, make
At accident.It in response to this, is zero in the output signal of load transducer currently, using the setting program in electric loop
When at once stop Xiamen, it is likely that just having broken off relations when load is zero, simultaneously because the inertia of lifting mechanism, grasping beam can
It can continue downslide a small distance, therefore using electrical control and unreliable.

Tightly.
In preferred scheme, the locking means of the dropproof locking device of grasping beam as described above, it includes the following steps:
S1 is mentioned in front of the door, and grasping beam is separated with gate, and weight is located at the right side of grasping beam, and suspension hook is in plumbness, not with gate dog
Even, the horizontal adjustment screw 32 on rolling mechanism 3 and suspension hook are contactless, and dropproof locking device does not work；
S2 mentions Men Suoding, and the first limiting slot 33 on roller beam 31 is corresponding with the spliced eye 13 of position-limited rack 1, by position-limit mechanism 5
It limits after plate 51 is inserted into spliced eye 13 and cooperates with the first limiting slot 33, the limited mouth 63 and limit plate 51 on lockplate 61
The cooperation locking of limiting stand 53；
S3 after gate is mentioned, before relaying tail gates, will mention a latch-release, pull up lockplate 61, disengage it from
With the cooperation of limit plate 51, then outside withdrawing position-limit mechanism 5, make to limit the disengaging of plate 51 and the first limit on roller beam 31
The cooperation of slot 33, roller beam 31 are in active state；
S4 connects gate, weight is pulled to the right side of grasping beam, and link mechanism drives the suspension hook of grasping beam two sides to middle shrinkage,
Grasping beam decline, suspension hook gradually pin shaft on gate when stop decline, then weight is pulled on the left of grasping beam, link mechanism band
The suspension hook of dynamic grasping beam two sides is gradually vertical, and the pin shaft hook on suspension hook and gate connects；
S5, Xiamen locking, the limit plate 51 and roller beam 31 of position-limit mechanism 5 are detached from, and are in no mating condition, are twitched lock upwards
Fixed board 61, by roller beam 31 to a Slideslip, after contradicting horizontal adjustment screw 32 and suspension hook, lockplate 61 falls and roller beam
The second limiting slot 34 on 31 cooperates locking；
S6, Xiamen latch-release, when grasping beam continue decline when, gate is contacted with ground sill, mandril along gate upward sliding with it is vertical
It adjusts screw 64 to contradict, is detached from lockplate 61 and cooperates with the second limiting slot 34 on roller beam 31, roller beam 31 is in activity
State.This method is simple to operate, the state of lockable lift hook unhooking or hook even, the state after locking in grasping beam lifting process
Stablize, is not easy maloperation, securely and reliably.
The dropproof locking device of grasping beam as described above, when installing and using, bearing block 4 and position-limited rack 1 and fixed frame 2 connect
It connects, rolling mechanism 3 passes through position-limited rack 1 and fixed frame 2 and bearing block 4 rolls and cooperates, position-limit mechanism 5 and 1 grafting of position-limited rack and rolling
