crew Jack, Trapezoidal/Ball Screw Lifter, Self-Locking Lifting Platform for Automation

The SWL/SJB series screw jack is a basic lifting and adjusting component that converts rotary motion into linear motion. With a core structure of worm gear + screw nut, it enables load lifting, pushing, translating, and tilting. Supporting capacities from 100kg to 120t (up to 500t for heavy-duty models) and precision up to ±0.1mm, it is available in trapezoidal screw (self-locking) and ball screw (high-efficiency) configurations. Widely used in industrial automation, metallurgy, mining, construction, stage, medical and food industries, it can be used alone or synchronized in multiple units.

产品定义及工作原理

螺旋千斤顶（也称蜗轮蜗杆升降机）是一种基本的升降调节装置，它将旋转运动转换为直线运动。其核心结构为蜗轮蜗杆+螺母，由电机或手轮驱动。蜗杆旋转带动蜗轮蜗杆减速并放大扭矩，然后蜗轮蜗杆带动螺母旋转，推动螺杆做直线运动（或者螺杆固定不动，螺母移动），从而实现负载的提升、推动、平移和倾斜等动作。

🛠️核心结构与主要类型

  1. 电源端可选电动（电机）或手动（手轮）驱动模式
  2. 还原机制主流型蜗轮蜗杆传动（自锁性强、噪音低、安装方便）；可选齿轮传动（效率高、速度快、需要配置制动器）
  3. 驱动副：
    • 梯形螺杆：滑动摩擦，自锁防止脱落，成本低，效率25%-40%
    • 滚珠丝杠：滚动摩擦，效率高达92%-98%，精度高，无自锁，成本较高
  4. 螺杆运动类型：
    • 螺杆运动方式：螺母固定、螺杆伸缩、大行程
    • 螺母移动类型：螺杆固定、螺母提升、长度短、刚性高

👍 性能特点

  • 紧凑结构体积小、重量轻、安装灵活，适用于空间受限的场景
  • 强大的承载能力标准承载能力2.5-120吨，重型定制可达500吨，满足工业重载需求。
  • 精确定位精度高达±0.1mm，适用于精密调节应用
  • 安全自锁梯形螺杆具有断电自锁功能，可防止负载坠落，从而提高安全性。
  • 多单元同步支持2/4/8台设备同步运行，实现稳定、平稳、无抖动的升降平台运行。

⚠️ 注意事项

  • 梯形螺杆效率低，不适合长时间高速连续运行；应根据占空比使用。
  • 滚珠丝杠不具备自锁功能，需要制动器或制动电机来防止负载滑动。

📌 典型应用

  • 工业自动化生产线升降平台、工装定位、机床Z轴、同步升降平台
  • 冶金/采矿：炉门提升、闸门开启/关闭、重物顶升、矿山设备调整
  • 施工/舞台舞台升降机、灯架调节器、升降机、建筑设备
  • 医疗/食品：医院病床升降、包装机高度调节、食品设备定位
