The loading wheel lifting device comprises a vehicle body, a pallet fork frame arranged on one side of the vehicle body and a fork arm arranged on one side of the pallet fork frame, a loading wheel assembly is hinged to one side of the interior of a groove in the lower portion of the fork arm, a mounting base is arranged on the other side of the pallet fork frame, and a first connecting rod is hinged to the interior of the mounting base; a foot lifting hydraulic cylinder is hinged to the middle of the first connecting rod, the telescopic end of the foot lifting hydraulic cylinder is connected with a loading wheel assembly through a second connecting rod, the loading wheel assembly comprises a third connecting rod hinged to one side of the fork arm, a loading wheel is arranged in the third connecting rod, and one end of the second connecting rod is hinged to the third connecting rod. The foot lifting hydraulic cylinder is controlled to retract, so that the second connecting rod is pulled, the third connecting rod is driven to rotate with the hinge point as the center, the loading wheel is lifted, the high-position lifting state and the low-position lifting state of the loading wheel are achieved, the structure principle is extremely simple, the occupied space is small, and the space in a vehicle body is not occupied.
本发明公开了一种用于托盘车的负重轮提升装置,包括车体、设置在车体一侧的货叉架以及设置在货叉架一侧的叉臂,叉臂的下部凹槽内部一侧铰接链接有负重轮组件,货叉架的另一侧设置有安装座,安装座内铰接有第一连杆,第一连杆的中部铰接链接有抬脚液压缸,抬脚液压缸的伸缩端通过第二连杆连接负重轮组件,负重轮组件包括铰接链接叉臂一侧的第三连杆,第三连杆内设置有负重轮,第二连杆的一端铰接第三连杆。通过控制抬脚液压缸进行回缩动作,从而拉动第二连杆,带动第三连杆以铰接点为中心转动,来实现负重轮提升,实现其高位抬升和低位抬升状态结构原理及其简单,占用空间小,且不占用车体内空间。
