为避免因升降平台液压缸的推力过大导致液压缸的直径过大,在同样安装尺寸起程角减小,减小安装尺寸能有效的加大起程角,因此选用两个直径小的液压缸代替一个直径大的液压缸,并确定液压缸的类型与结构。
To avoid Zhejiang lifting platform hydraulic cylinder thrust is too large hydraulic cylinder diameter is too large, the same dimensions departure angle decreases, reducing the installation size can effectively increase the departure angle, so use two small diameter cylinder instead of a large diameter cylinder, and to determine the type and structure of the hydraulic cylinder.

升降平台在两相对剪叉臂间与液压缸活塞杆受力支点处,焊接一个连接杆增强剪叉臂整体刚度,升降台运行的过程,控制剪叉臂因压力不均滑行不同步,使升降台升降保持平衡。液压缸的安装位置不同,行程、推力以及起程角均不同,因此液压缸的安装位置非常重要,其安装的最佳位置就是在满足使用要求的前提下,使得液压缸的推力最小。通过比较找出最合适设计要求的设计方案,进行结构设计。在满足升降平台结构设计的基础上对受力较大的零构件进行强度计算和刚度校核,验证是否满足设计要求。
Zhejiang lifting platform between opposing scissor arm and the piston rod force at the fulcrum, solder a connecting rod to enhance the overall stiffness of the scissor arm, lifting process running, the control arm scissors glide out of sync due to uneven pressure, make lifts lift balance. Installation position of the hydraulic cylinder, stroke, thrust and departure angles are different, so the installation position of the hydraulic cylinder is very important, the best place to install it is to meet the requirements under the premise of making the hydraulic cylinder thrust is minimized. By comparison to identify the most appropriate design requirements design, structural design. Zhejiang lifting platform to meet the structural design on the basis of a larger force of zero means strength calculation and stiffness Verification, Validation meets the design requirements.

    导轨式升降机里运用比较普遍的是导轨式升降机。这是一款用途很广的高空作业设备。它和别的升降机的区别就是它的导轨链条式结构,这也是它的优势所在。因为这样的导轨结构保证普通升起和下降都是很稳定的,不像其它结构的升降机有摇晃的感觉,特别是载物比较...
