The invention discloses an obstacle crossing type hand fork lifter, which comprises a base frame and a transmission belt, vertical plates are fixedly connected to the front side and the rear side of the left side of the top of the base frame, and fixing blocks are fixedly connected to the front side and the rear side of the two sides of the bottom of the base frame; cross rods are mounted on the adjacent sides of the two fixing blocks in a penetrating manner; the structural design is reasonable, during transportation of workers, smooth pushing is conducted through crawler wheels and a transmission crawler belt, stability of triangular plates can be kept during pushing through fixed connection of the cross rods and the triangular plates, the situation that the triangular plates rotate, and the pushing effect of the workers is affected is avoided, and when the workers meet obstacles (such as deceleration strips and steps), a first servo motor can drive a double-shaft belt pulley to rotate, and when the double-shaft belt pulley rotates, a driven belt pulley and a sleeve rod are driven to rotate through transmission connection of a transmission belt, so that the triangular plates are driven to rotate, and an obstacle is climbed over.
本发明公开了手动叉车技术领域的一种越障式手动叉车,包括底座框架和传动皮带,所述底座框架顶部左侧的前后两侧均固定连接有竖板,所述底座框架底部两侧的前后两侧均固定连接有固定块,两个所述固定块相邻的一侧均贯穿安装有横杆;本发明结构设计合理,在工作人员运输时,通过履带轮与传动履带进行平缓的推动,且通过横杆与三角板的固定连接能够在推动时保持三角板的稳定性,避免三角板出现转动,影响工作人员推动的效果,在遇到障碍物时(如减速带、台阶等),通过设有的第一伺服电机能够带动双轴皮带盘进行转动,在双轴皮带盘转动时通过传动皮带的传动连接带动从动皮带盘和套杆进行转动,从而带动三角板进行转动,对障碍物进行翻越。
