Above-mentioned active reel is identical with diameter from movable reel, and when same rotational speed, the linear velocity of two winding drum is identical, the rope of folding and unfolding just equal in length.Steel rope the active reel with from movable reel around to identical, and the wiring reference position is the same, but initial wiring asynchronism(-nization): when the active reel when full, just begun to twine from movable reel.Like this when initiatively reel is put rope,, thereby realize the pressure folding and unfolding of steel rope from movable reel wiring just in time.
Above-mentioned double-drum synchronous hoister, its actuating unit comprises HM Hydraulic Motor and planetary reducer, and the clutch end of HM Hydraulic Motor and the power intake of planetary reducer join, and the takeoff output termination of planetary reducer is reel initiatively.
Above-mentioned double-drum synchronous hoister, its frame is the rectangular box open frame, is welded with steel plate, is the main body frame of this winch, other parts all are fixed on the frame, form an integral body.
Above-mentioned double-drum synchronous hoister, it initiatively offers well-regulated drum rope groove on the reel, and drum rope groove is used rule row rope with the rope winding jib that is arranged on the frame.Above-mentioned rope winding jib comprises presses rope roller, lever and extension spring; Press the rope roller to be arranged on the initiatively below of reel; Its two ends are connected with the middle part of two levers respectively; One end of lever is fixed on the frame, and the other end of lever is connected with the bottom of extension spring, and the upper end of extension spring is fixed on the frame.
Above-mentioned double-drum synchronous hoister, it offers well-regulated drum rope groove from movable reel, and drum rope groove is used rule row rope with the rope winding jib that is arranged on the frame.Rope winding jib comprises presses rope roller, lever and extension spring; Press the rope roller to be arranged on below from movable reel; Its two ends are connected with the middle part of two levers respectively; One end of lever is fixed on the frame, and the other end of lever is connected with the bottom of extension spring, and the upper end of extension spring is fixed on the frame.
Above-mentioned rope winding jib adopts lever principle; In advance that rope processing device is required precompressed compression is stored in the extension spring, and the predetermincd tension of extension spring, is being pressed under the rope roller pressure in pressing on the rope roller through the lever amplification; Steel rope twines along drum rope groove; Do not apply and force under the external force situation, steel rope can not be jumped out from grooving, and this has just played the effect of regular row's rope.
Above-mentioned double-drum synchronous hoister, it is equipped with the measure speed gears of the usefulness that tests the speed from movable reel, and measure speed gears and measurement mechanism join, and measurement mechanism is connected with controller through Hall element.Measure speed gears mainly is for measurement mechanism provides pulse, and according to number of pulses, counting machine can be measured the angle of reel rotation, handles through series of computation, just can on telltale, directly show folding and unfolding rope length and speed.
Double-drum synchronous hoister of the present invention compared with prior art, the beneficial effect that is produced is:
1) bitubular synchronization structure has been realized bitubular high-precise synchronization folding and unfolding rope, has satisfied the requirement of stake construction equipment technical development.
2) be provided with the rope winding jib that rule is arranged rope usefulness, disorder cable, folded rope phenomenon in winch folding and unfolding rope process, can not occur, thereby guaranteed the service life of steel rope and the precision of folding and unfolding rope.
3) be provided with speed measuring device, can very accurately measure winch folding and unfolding rope length, but detection at any time folding and unfolding rope speed and length have satisfied piling machinery to the automation control requirement of transition.
