Actuating unit drives two drive links 8 by transmission component, and then drives all synchronous axial systems of pivotal support arm 7,
Lifting frame 9 is driven to rise or fall with this, roller-way 10 rises or falls with lifting frame 9.
The lifting principle of above-described embodiment：When technological requirement roller-way 10 rises to certain altitude, actuating unit passes through biography
Dynamic component drives two synchronization actions of drive link 8, and then drives all synchronous axial system certain angles of pivotal support arm 7, sees Fig. 2 institutes
Show, drive lifting frame 9 to rise to certain altitude with this, roller-way 10 rises with lifting frame 9 is synchronous；When technological requirement roller-way 10
When dropping to certain altitude, actuating unit drives all synchronous backwards of pivotal support arm 7 to turn an angle, and makes roller-way 10 steady
Decline.
Above-mentioned the present embodiment is using at least four pivotal support arms for being evenly distributed on roller-way opposite sides and synchronous axial system
7, realize the steady lifting of roller-way 10；Just because of the synchronism of all pivotal support arms 7 is good, fast response time is easy to adjust, from
And roller-way 10 is set to lift steadily.Further, since the top of lifting frame 9 and all pivotal support arms 7 is rotatedly connected, with lifting frame
The stability that the connected roller-way 10 of frame 9 lifts is stronger.
Need to drive two synchronization actions of the drive link for being distributed in roller-way opposite sides 8 in view of actuating unit, thus it is dynamic
Force mechanisms are located at the middle of roller-way opposite sides, and actuating unit has a motor 2 and two are coaxially disposed and court respectively
The output shaft extended to roller-way opposite sides, two output shafts are connected with motor 2, and above-mentioned transmission component includes two symmetrically
The sub- transmission component of roller-way opposite sides is arranged on, the output shaft, sub- transmission component and drive link 8 positioned at homonymy are sequentially connected.
This structure advantageously reduces the output torque of actuating unit, has both met technological requirement and in turn simplify roller-lifting mechanism in itself
Structure.
In order that actuating unit dismounting, maintenance simplicity, actuating unit also include reductor 3, motor 2 and reductor 3
It is connected, reductor 3 has two above-mentioned output shafts.When motor 2 is run, two output shaft synchronous rotate, and two
Output shaft drives the principle of drive link 8 identical by corresponding sub- transmission component.
Specifically, reductor 3 is helical gear reduction gear of bevel gear, and its meshing performance is good, vibration is low, noise is small, transmission is flat
Surely.Motor 2 is synchronous motor：First, synchronous motor can under very low power frequency operation, small volume, efficiency high.Again
Person, the stabilization of speed of synchronous motor, reliability is high, meets the requirement of the present embodiment high-precise synchronization driving.Finally, its unit
What capacity hardly limited by, can accomplish very high power, and overload capacity is strong.
In order to simplify the structure of above-mentioned sub- transmission component, transmission efficiency is improved, as shown in figure 3, every sub- transmission component bag
Include power transmission shaft 4, crank 5 and pull bar 6, one end of power transmission shaft 4 and coaxial connected and its other end of corresponding output shaft and crank 5
One end be vertically connected, the other end of crank 5 is connected by pull bar 6 with corresponding drive link 8.Because the present embodiment is located at respectively
The structure and its driving principle of roller-way opposite sides are identical, now only with roller-way side explanation：The output shaft and power transmission shaft of reductor 3
4 end flange is connected, and the other end of power transmission shaft 4 is also to be vertically connected by one end of flange connection and crank 5, crank
5 other end is connected by self-lubricating rod end spherical plain with one end of pull bar 6, and the other end of pull bar 6 is also to pass through self-lubricating
Spherical plain bearing rod end is connected with one end of drive link 8, and the both ends of drive link 8 are respectively by self-lubricating rod end spherical plain with being located at
All pivotal support arms of this side of roller-way turn 7 and are connected.As another preferable connected mode, the other end of pull bar 6 passes through
The lower end that self-lubricating rod end spherical plain and a pivotal support arm turn 7 is hinged, the pivotal support arm turn 7 lower end again with drive link
8 one end is hinged, more stable using this connected mode, transmission.Specific transmission process is as follows：First, the output of reductor 3
Axle rotates；Secondly, power transmission shaft 4 is with output shaft rotation；Furthermore crank 5 rotates around the axis of power transmission shaft 4；Then, crank 5 passes through drawing
Bar 6 drives drive link 8；Then, the synchronous axial system of pivotal support arm 7 of the same side；Finally, lifting frame 9 is in pivotal support arm 7
Lifted under synchronous axial system.Because roller-way 10 is arranged on lifting frame 9, roller-way 10 is raised or lowered to lifting frame 9
Setting height.
In order to accurately control the stroke that roller-way 10 lifts, if as shown in figure 4, the periphery of at least one power transmission shaft 4 is provided with
The metal sensor block 11 of dry circumference array, base are provided with and rotated with all metal sensor blocks 11 on same power transmission shaft 4
Corresponding inductive switch 12.As a kind of more excellent design, above-mentioned power transmission shaft 4 includes coaxially connected long power transmission shaft and short pass and moved
Axle, long power transmission shaft are coaxially connected with corresponding output shaft, and one end of short pass moving axis and crank 5 is vertically connected, and the two of short pass moving axis
End is connected by bearing block with base 1, radial vibration during short drive axis can be so avoided, so as to improve inductive switch
12 with the induction precision of metal sensor block 11.Wherein, above-mentioned long power transmission shaft is a kind of Cardan shaft, can eliminate assembling
Error and reduction parts vibrate the influence to transmission efficiency.
Specifically, the central angle of adjacent metal sensor block 11 is 180 degree.Exported when motor 2 is driven by reductor 3
Axle rotates forward 180 degree, and power transmission shaft 4 rotates forward 180 degree with output shaft.When inductive switch 12 detects metal sensor block 11 i.e.
Sender is carved, motor 2 stops operating and waited into next action at once.Now, roller-way 10 rises to certain altitude
(see Fig. 2).If it is intended to making roller-way 10 drop to original height, restart motor 2, motor 2 passes through reductor 3
Drive output shaft to reversely rotate 180 degree, roller-way 10 drops to original height (see Fig. 1).As a kind of more excellent design, sensing
Switch 12 is a kind of proximity switch, and it has reliable in action, stable performance, frequency response is fast, application life is long and anti-interference energy
The advantages that power is strong, and also there is waterproof, shockproof, corrosion-resistant, do not influenceed by the environment of roller-way 10.
To sum up, the utility model is using at least four rotation supports for being evenly distributed on roller-way opposite sides and synchronous axial system
Arm, realize the lifting action of roller-way；The synchronism of all pivotal support arms is good, and fast response time is easy to adjust, so that roller-way
Lifting steadily.So the utility model effectively overcomes various shortcoming of the prior art and has high industrial utilization.
