Specific embodiment
The present invention can be used for the automatic clutch operation in various occasion lifting process, davit (1) and the connection lifting of (8) upper end
Connection weight under mechanism, base plate (5), when weight is lowered into ground by elevating mechanism, suspension ring (4), suspension ring (6) stop fortune
Dynamic, whole lowering or hoisting gear continues to decline a little distance to suspension hook (3), suspension hook (7) correct position in suspension ring, now slide block
(22) near the position of travel switch (18), motor (12) is then allowed to rotate forward operation in circuit control system, by tooth
Wheel transmission drives the motion of positive and reverse return feed screw nut, and slide block (22) is with slide block (31) away from motion, driving lever (27) thereon and driving lever
(34) as slide block is away from motion, until promoting suspension hook (7) to cause suspension hook rotation to progressively disengage suspension ring with the top of suspension hook (3)
(6) with suspension ring (4), during disengaging, when slide block (22) touches travel switch (23), the signal that travel switch is produced passes through
Circuit control system makes motor shut down, because motor stops having certain self-locking moment, so suspension hook one
It is straight to keep heeling condition, then davit is risen into certain altitude, therefore suspension hook suspension ring successfully separate, when needing separated weight again
It is secondary that as long as the hoisting ring device of connection weight is placed on into correct position under suspension hook, davit is dropped at the position before rising when lifting,
Motor reversion is allowed to run, now slide block (22), slide block (31) run in opposite directions from extreme position, driving lever (27), driving lever (34)
Suspension hook top is progressively disengaged, suspension hook screws under gravity suspension ring, when slide block (22) touches limit switch (18), stepping electricity
Machine stops operating, and now suspension hook suspension ring are combined and finished, and elevating mechanism can be by heavy lift.Whole crampon suspension ring automatic clutch
Device can be used in automatic production line, and structure is safe and reliable, scene can Unmanned operation, save manpower, work efficiency is significantly
Improve.
