The invention provides a mechanical auxiliary lifting device, and belongs to the technical field of intelligent cranes. The technical problem that an existing intelligent crane is poor in adaptabilityand cannot hoist some special objects is solved. A worm and gear reduction gearbox of the mechanical auxiliary lifting device is fixedly connected with a fixed plate, a guide rod fixed to the fixed plate is slidingly provided with a movable plate, a hook is fixed to the movable plate, a worm of the worm and gear reduction gearbox is fixedly connected with a first screw, the first screw is matchedwith a nut fixed to the movable plate, second screws are symmetrically arranged on the left side and the right side of the worm and gear reduction gearbox, the inner ends of the second screws are fixedly connected with a worm gear of the worm and gear reduction gearbox, movable pieces sleeving the outer ends of the second screws correspondingly are provided with limiting grooves or limiting holes, and limiting pieces are fixed on the left side and the right side of the fixed plate. By means of the mechanical auxiliary lifting device, vertical tensile force is converted into transverse supporting force or clamping force, objects not convenient to directly hang are conveniently hoisted, and the applicability of the intelligent crane can be easily improved.
本发明提供了一种机械式的辅助提升装置,属于智能吊技术领域。它解决了现有智能吊适应性较差,无法吊起一些特定的物件的技术问题。本机械式的辅助提升装置的涡轮蜗杆减速箱与固定板固连,固定板上固定的导向杆可滑动设置有活动板,活动板上固定有挂钩,涡轮蜗杆减速箱的蜗杆与第一螺杆固连,第一螺杆与活动板上固定的螺母配合,涡轮蜗杆减速箱的左右两侧对称设置有第二螺杆,第二螺杆的内端与涡轮蜗杆减速箱的涡轮固连,第二螺杆的外端部均套设的活动件上设有限位槽或限位孔,固定板的左右两侧固定限位件。本发明将竖向的拉力转化为横向的支撑力或夹持力,便于将不方便直接悬挂的物品吊起,有利于提高智能吊的适用性。
