The invention relates to a standing-driving type electric carrier and a lifting mechanism thereof, the lifting mechanism comprises a frame, a pallet fork mechanism, a lifting oil cylinder configured to drive the pallet fork mechanism to move up and down relative to the frame, the lifting oil cylinder has an adjusting angle inclined in the vertical direction, and a connecting rod mechanism comprising a swing rod and a long connecting rod, the first hinged end of the swing rod is hinged to the frame, the second hinged end of the swing rod is hinged to the pallet fork frame, the third hinged end of the swing rod is hinged to one end of the long connecting rod, and when the pallet fork mechanism moves up and down, the pallet fork frame drives the swing rod to push or pull the long connecting rod, so that the load wheel assembly at the front end of the long connecting rod is switched between a first state and a second state. According to the scheme, the front load wheel set of the pallet fork is driven to stretch out or retract while the pallet fork is controlled to ascend and descend through the driving mechanism, and production and control are easy.
本发明涉及一种站驾式电动搬运车及其起升机构,起升机构包括车架,货叉机构,起升油缸,配置为驱动货叉机构相对于车架上下运动,所述起升油缸具有在竖直方向上倾斜的调节角度,连杆机构,包括摆杆和长连杆,摆杆的第一铰接端与车架铰接,摆杆的第二铰接端与货叉架铰接,摆杆的第三铰接端与长连杆的一端铰接,在货叉机构上下运动的同时,货叉架带动摆杆推动或拉动长连杆,使长连杆前端的负载轮总成在第一状态和第二状态之间切换。本方案通过一组驱动机构控制货叉升降的同时带动货叉前负载轮组伸出或缩进,且生产及控制简单。
