First rotating shaft 11, second rotating shaft 14, the 3rd rotating shaft 22 and 23 pivotally attached underframe 9 of the 4th rotating shaft, the arm 19 of turning right, first balancing pull rod 16 and tong arm 7 are formed first parallel-crank mechanism, the outer tong arm 13 of the 6th rotating shaft 25, the 5th rotating shaft 24, the 4th rotating shaft 23 and 26 pivotallys attached of the 7th rotating shaft, the arm 20 of turning left, tong arm 7 and second balancing pull rod 27 have been formed second parallel-crank mechanism, in order to make above-mentioned two parallel-crank mechanisms keep between first rotating shaft 11, second rotating shaft 14 and the 7th rotating shaft 26, synchronous plate 15 being housed synchronously.
Turn left at two and between arm 20 and two tong arms 7 mechanism for opening/closing 6 to be housed, after clamping coil of strip, the perpendicular volume of single armed suspender carries out when mobile, mechanism for opening/closing 6 upward movements break away from the lock be fixed on the tong arm 7, and the effect by leverage makes outer tong arm 13 and internal clamp port 21 withstand coil of strip tightly.After the perpendicular volume of single armed suspender moves on to preposition with coil of strip, mechanism for opening/closing 6 moves downward, and the tapered end of T-shape is stuck on the lock that is fixed in tong arm 7, then upward movement, suspender is in open state puts down coil of strip, and the perpendicular volume of single armed suspender is finished a lifting action.
In order to catch coil of strip better, outer jaw assembly 12 is equipped with in the lower end of outer tong arm 13, and an internal clamp port 21 is equipped with in the lower end of underframe 9.
Principle of work
The perpendicular volume of this single armed suspender is when overhead traveling crane is sling suspender, make it be in open state, as the perpendicular volume of single armed suspender is in closure state when slinging, can be by the decline suspender, make its kiss the earth, the tapered end of mechanism for opening/closing 6 will move down, because the restriction of spiral chute, tapered end meeting half-twist, make down " T " the tapered end bottom of type hooks lock, at this moment suspender just is in open state, starting overhead traveling crane makes suspender run to the top of vertical steel coils, slowly fall, the internal clamp port 21 of suspender is entered in the internal diameter of coil of strip, continue to fall, no longer bear the deadweight of suspender up to overhead traveling crane, at this moment the suspender pulsation-free is placed on the coil of strip, simultaneously because the effect of gravity, the height of suspender is in reducing gradually, tapered end up to mechanism for opening/closing 6 touches the lock bottom, tapered end is half-twist under the double action of gravity and spiral chute, fall " T " tapered end of type breaks away from lock, start overhead traveling crane, the left connecting rod 4 of suspender, the leverage that right connecting rod 5 and left and right sides connecting lever are formed draws in gradually, left and right sides connecting lever pivots, the inwardly motion of connecting lever bottom, the left and right sides, by tong arm 7, the arm 19 of turning right, first parallelogram lindage that the underframe 9 and first balancing pull rod 16 are formed drives internal clamp port 21 levels and inwardly moves, by tong arm 7, the arm 20 of turning left, second parallelogram lindage that the synchronous plate 15 and second balancing pull rod 27 are formed drives outer jaw assembly 12 and inwardly moves, the outer diametric plane and the aperture surface that make outer jaw assembly 12 on the outer tong arm 13 and the internal clamp port 21 on the underframe 9 clamp vertical steel coils respectively, this moment, the center of gravity of suspender also moved to the coil of strip center of gravity, the center of gravity of suspender and coil of strip is overlapped substantially, it hitch continues upward movement, coil of strip is picked up by pulsation-free, overhead traveling crane is reached the desired location, it hitch slowly falls, behind the coil of strip kiss the earth, spreader height descends gradually, left and right sides connecting lever drives internal clamp port 21 and outer jaw assembly 12 outwards moves, suspender is the clamping coil of strip no longer, and it is no longer stressed up to the sky hitch to continue to fall.The tapered end of mechanism for opening/closing 6 once more since the effect half-twist of gravity and spiral chute fall " T " tapered end of type is hooked on the lock once more.Upwards start overhead traveling crane, suspender is sling under open state.Finish lifting job one time.
Above described only be to the mode of operation of the perpendicular volume of single armed suspender and the description of principle; be not that design of the present utility model and scope are limited; do not breaking away under the prerequisite of the present utility model; various modification and improvement that engineering staff in this area make the technical solution of the utility model all should fall into protection domain of the present utility model, and the technology contents that the utility model is asked for protection will be as the criterion all to be documented in right.
