The invention relates to the technical field of forklift platforms, and discloses a forklift platform lifting improvement device which comprises a bottom plate, a containing groove penetrating through the bottom wall face of the bottom plate is formed in the end, away from a push plate, of the top wall face of the bottom plate, and four circumferentially-distributed fixing frames are fixedly installed on the bottom wall face of the bottom plate; and a cross-shaped connecting frame is arranged at the bottom of the bottom plate. According to the invention, the elasticity of the buffer spring is utilized to limit the moving speed of the extension rod and the connecting rod, so that the situation that the connecting rod and the extension rod are suddenly blocked in movement due to too high moving speed of the connecting rod and the extension rod is avoided; the pressurizing springs are fixedly connected to the wall faces of the sides, away from each other, of the two limiting blocks in the containing frame, when the connecting rods and the extending rods contract towards the interior of the containing frame, the movement speed of the limiting blocks is limited through the elasticity of the pressurizing springs, and the situation that the limiting blocks are blocked when the limiting blocks return to the original positions is avoided.

    本发明涉及叉车平台技术领域,且公开了一种叉车平台的升降改进装置,包括底板,底板的顶部壁面远离推板的一端开设有贯穿底板底部壁面的容纳槽,底板的底部壁面固定安装有四个圆周分布的固定架,底板的底部设置有呈“十”字形的连接架。本发明中,利用缓冲弹簧的弹性,对延伸杆和连接杆的移动速度进行限制,避免连接杆和延伸杆移动速度过快,导致连接杆和延伸杆的移动出现突然卡顿的情况发生,通过在容纳框内部的两个限位块上相远离的一侧壁面均固定连接上增压弹簧,当连接杆和延伸杆向容纳框的内部收缩时,利用增压弹簧的弹性限制限位块的移动速度,避免限位块在恢复至原位时出现卡顿的情况发生。
