Background technique
For shearing type lifter when decline is close to extreme lower position, oil cylinder angle is based on level, and machine dramatic decrease leads to machine
Judder, which occurs, for device upper cover can also generate violent collision and sound if machine upper cover is in contact with machine bed plate at this time
It rings.The service life of machine is not only influenced in this way, moreover it is possible to generate noise pollution, or even have the danger for falling vehicle.
Shearing type lifter designs the angle of oil cylinder so space is limited when extreme lower position to lift the vehicle of low chassis
The diameter of very little, oil cylinder is also limited, and jacking capacity is difficult to guarantee.
Summary of the invention
It is an object of the invention to overcome above-mentioned technical deficiency, one kind is provided and steadily declines and reduces cutting for oil cylinder load
Formula lifting machine decline buffering and rising servomechanism.
The technical issues of the utility model solves, used technical solution is: a kind of shearing type lifter decline buffering and
Rise servomechanism, including pedestal, lifting mechanism seat C is housed in the left end of pedestal, is equipped with and cuts at the both ends of lifting mechanism seat C
Arm, is equipped with central axis at the center for cutting arm, and lifting mechanism D, lifting mechanism E are housed in the two sides of central axis；Cut the upper end dress of arm
There is upper axis, upper axis both ends are actively equipped with upper roller；Upper roller is slidably connected with the slideway that hoistable platform is fixed below；Lifting machine
The right end and sliding axis connection of structure E, sliding axle is on sliding block, and sliding block is slidably connected with pedestal, and two are cut above the right side of arm
It is fixed with lifting mechanism connecting plate D；It is fixed with lifting mechanism connecting plate E below on the right side of two lifting mechanism E；It is characterized in that lifting
Mechanism E inside middle portion board connective axis is flexibly connected with connecting plate A, and axis is flexibly connected with booster on the right end oil cylinder of connecting plate A, is helped
Fill on center shaft to power device central movable, the right end of booster is fixed with ground roll wheel shaft, the both ends of ground roll wheel shaft actively
Equipped with Ground roller；Booster is flexibly connected with the piston rod end of hydraulic cylinder with axis on oil cylinder.
The utility model has the beneficial effects that connecting plate and booster are formed by angle when utility model decline buffering
It is gradually increased, the steady decline of machine is realized by this process；When rising power-assisted, on lifting machine is since extreme lower position
When rising, lifting force is provided jointly by hydraulic cylinder and booster, reduces the load that hydraulic cylinder is born.

Specific embodiment
Embodiment a kind of shearing type lifter decline buffering and rises servomechanism, including pedestal 20 referring to attached drawing, the bottom of at
The left end of seat 20 is equipped with lifting mechanism seat C22, at the both ends of lifting mechanism seat C22 equipped with arm 8 is cut, is equipped at the center for cutting arm 8
Central axis 6 is equipped with lifting mechanism D9, lifting mechanism E25 in the two sides of central axis 6；The upper end of arm 8 is cut equipped with upper axis 14, upper axis
14 both ends are actively equipped with upper roller 17；The slideway 15 that upper roller 17 is fixed below with hoistable platform 13 is slidably connected；Lifting machine
The right end of structure E25 is connect with sliding axle 24, and sliding axle 24 is on sliding block 23, and sliding block 23 is slidably connected with pedestal 20, and two are cut
The right side of arm 8 is fixed on lifting mechanism connecting plate D26；It is fixed with lifting mechanism connecting plate below on the right side of two lifting mechanism E25
E27；It is characterized in that being flexibly connected with board connective axis 4 with connecting plate A1 in lifting mechanism E25 inside middle portion, the right end oil of connecting plate A1
Axis 5 is flexibly connected with booster 2 on cylinder, is mounted on central axis 6 to 2 central movable of booster, the right end of booster 2 is fixed with ground
Roller shaft 3 is actively equipped with Ground roller 7 at the both ends of ground roll wheel shaft 3；The piston rod end of booster 2 and hydraulic cylinder 10 is used
Axis 5 is flexibly connected on oil cylinder.
It is respectively arranged with upper sweep 11 at the both ends of hoistable platform 13, end face is fixed with hoistable platform seat 12；It is left in pedestal 20
Saddle 21 under arm are cut outside being fixed in the two sides at end, cut saddle 21 under arm outside and are flexibly connected with lifting mechanism seat C22, dress among right side
There are lock rack gear 19 and safe lock set 18, right end end is equipped with limit plate 16.
The working principle of the utility model is:
Decline buffering: the cavity of resorption adapter tube of hydraulic cylinder 10 is slowly drained the oil, and decrease speed is controlled, when machine is dropped to away from ground
When 195mm, Ground roller 7 is contacted with the generation of pedestal 20 and is slowly slided from left to right along pedestal 20, while board connective axis 4 is along even
The movement of plate A1 from left to right.With the decline of machine, connecting plate A1 is formed by angle with booster 2 and is gradually increased, until rising
Drop platform 13 drops to minimum altitude.The steady decline of machine is realized by this process.
Rise power-assisted: when hoistable platform 13 is begun to ramp up from extreme lower position, 10 cavity of resorption of hydraulic cylinder is taken over into high pressure oil,
Ground roller 7 slowly slides from right to left along pedestal 20, while board connective axis 4 is along the sliding from right to left of connecting plate A1.This
The lifting force of process is provided jointly by hydraulic cylinder 10 and booster 2, so reducing the load that hydraulic cylinder 10 is born.With
The rising of hoistable platform 13, connecting plate A1 be formed by angle with booster 2 and be gradually reduced, until board connective axis 4 slides into connecting plate
When A1 left end, Ground roller 7 starts to be detached from pedestal 20, and the lifting force of hoistable platform 13 is provided by hydraulic cylinder 10 completely, and this
When hydraulic cylinder 10 angle increased to completely can be with lifting force required for load.
