Abstract
The utility model relates to a two-piece shearing hydraulic lifting platform synchronous lifting mechanical device which makes the right and left piece platforms of the two-piece shearing hydraulic lifting platform lift synchronously and reliably. The synchronous rack gears are respectively hinged at one end of the inner side of each lower roller shaft of the two piece platforms; a ganged gear is supported in the middle by a belt seat outer sphere ball bearing; the bilateral synchronous rack gears are respectively engaged with the ganged gear; the synchronous rack gears slide in the rack gear sliding bush which always constrains the synchronous rack gears and the ganged gear from engaging. The rigid synchronizing mechanism comprising the synchronous rack gear and the ganged gear guarantees the dependable synchronous lifting of the right and left piece platforms of the two-piece shearing hydraulic lifting platform; Because the mechanical structure is arranged between the right and left piece shearing forks, the mechanism isn't influenced by the hydraulic system or the element performance. The rigid synchronizing mechanism restraints simultaneously the sinking phenomenon caused by the leakage of the hydraulic system and has simple structure and lower cost.

(2) utilize the control of oil cylinder embedded position sensor closed loop control system synchronously
About two platforms the built-in sensors oil cylinder is set respectively, test left and right sides piston motion elongation increment immediately and signal is sent into computing machine carry out relatively its error of computing, thereafter the instruction control electro-hydraulic proportional flow valve is regulated flow separately, reaches the purpose that adjusting piston is synchronized with the movement.The control convenience synchronized operation more exactly of this scheme is equipped with difficulty but cause the housing structure lengthening to cause, and has influence on required stroke behind the oil cylinder built-in sensors,
(3) utilize horizontal outer sensor closed loop control system control synchronously
The place is provided with a rectilinear transducer respectively at the horizontal travelling wheel of left and right sides bridging, measures the synchronous error of left and right sides travelling wheel, signal is passed to after the Computing control electro-hydraulic proportional flow valve regulate flow, reaches the synchronous purpose of control.But motion and control relation more complicated.
(4) utilize vertical outer sensor closed loop control system control synchronously
Position transduser is placed in the vertical surface of table top stroke, directly test journey error, and feed back to flow valve and adjust flow and control synchronously.When the straight line position transduser extended in the lifting table total travel, installation can feel to have certain difficulty, under some condition even will be difficult for realizing.Therefore, can take improved mode again, promptly the table top straight-line motion is converted to gyroscopic movement by the steel wire pulley of having mercy on, thereby again by the control of rotary encoder test error synchronously.
Above-mentioned (2), (3), that (4) scheme is applied to many bay-lift synchro control is respond well, and all has successful examples.But for the bay-lift of separate unit biplate structure, cost exceeds in luxury very much.And, to about two platforms test its kinematic error respectively and feed back to actuating unit again and regulate, under the dynamic frequency condition with higher, table top is subjected to the influence of transient error all the time and is stressed.Therefore, its limitation is all arranged.
