Hereinafter, the most step by step work process is described.
Step 1) upset lifting linear actuator elongation, the first swing arm drives hinged channel bar, channel bar band
Dynamic the first telescopic pole being attached thereto shortens, and tailgate bearing plate overturns enabling, the second scalable support simultaneously
Bar shortens under the drive of tailgate bearing plate.Along with the gradually elongation of upset lifting linear actuator, all right one way or the other stretch
Contracting strut reaches firmly to support 1 position (the shortening stroke end of telescopic pole is no longer shortened), and upset is lifted
Rising linear actuator then to extend, the first swing arm drives channel bar, and dead slot stroke walked by channel bar, and no longer driving can
Telescopic strut shortens.Until upset lifting linear actuator is elongated to lift linear actuator consistent, tailgate
Upset door opening process in upper position completes.
Step 2) shortening Tong Bu with lifting linear actuator of upset lifting linear actuator, tailgate bearing plate (or
Person and goods) decline under gravity, until the thick end in contact ground of tailgate bearing plate, decline process
Complete.Upset lifting linear actuator and lifting linear actuator then shorten, tailgate load-bearing thickness of slab end with
Ground contacts, it is impossible to decline again, and two telescopic poles can not shorten in hard 1 position that supports, so, and tail
Plate bearing plate (or and goods) with the hinge of tailgate bearing plate with telescopic pole is under gravity
Rotating shaft, in lower inclined position, until the tip of tailgate bearing plate contacts with ground, completes tilting procedure.
Step 3) under turn on position, rising and closing the door is lower inclined position, declines and the inverse mistake of door opening process
Journey, does not repeats them here.
Step 4) cargo platform is less than tailgate bearing plate tilting procedure under the first loading position altitudes
As follows, tailgate is when the first loading position, and upset lifting linear actuator shortens, and now tailgate is closed the door
Action, when tailgate bearing plate carries out closing the door certain angle scope (such as 60--80 degree), stopping is closed the door dynamic
Make, next perform door opening action, along with the gradually elongation of upset lifting linear actuator, two scalable supports
Bar shortens to hard 2 positions that support, until the contacting of platform tip and cargo platform.Upset lifting straight line performs
Device continues elongation, and swing arm drives channel bar, and dead slot stroke walked by channel bar, no longer drives telescopic pole to shorten.
Until upset lifting linear actuator is elongated to lift linear actuator consistent, cargo platform is less than tailgate height
In the case of degree, the tilting procedure in the first loading position completes.After loading and unloading, just carry out door-closing operation
Can realize closing the door.
By described stroke groove, described first telescopic pole and described second telescopic pole can be carried
