The invention discloses a weight lifting device, and belongs to the technical field of lifting equipment. The device comprises a bottom cylinder, a stud and a lever. The bottom cylinder comprises a base, a cylinder body and a screw barrel, and the stud comprises a stud rod, a clamping seat and a jacking table; the clamping seat is arranged in the cylinder body, an external thread on the stud rod is meshed with an internal thread on the screw barrel, and the jacking table is located above the screw barrel; and a supporting rod hole is formed in the stud rod, and a three-way bearing mechanism jointly formed by a center bearing, an upper radial bearing and a lower radial bearing on the jacking table is arranged on the jacking table of the stud. A round cover top becomes a new jacking table above the jacking table, and in addition, fine adjustment devices are further arranged on the base. The lifting device has the beneficial effects that a linear lifting manner and a spiral rising structure are adopted, so that lifting force can be amplified by multiple times, and the lifting device can bear the gravity of a relatively large object; the three-way bearing mechanism can enable the new jacking table to be in close contact with a supported object, and the new jacking table cannot rotate along with the rotation of the stud rod; and the device is convenient to carry, simple to operate and suitable for wide application.

    一种重物抬升装置,属于升降设备技术领域,包括底缸、螺柱和杠杆;其中底缸包括底座、缸体和螺筒,螺柱包括柱杆、卡座和顶台;卡座设置在缸体中,柱杆上的外螺纹与螺筒上的内螺纹互相齿合,顶台位于螺筒的上方;柱杆上设有支杆孔,螺柱的所述顶台上设有由心向轴承、上径向轴承和下径向轴承在顶台上共同构成的三向轴承机构;并且其中圆盖顶成为顶台上方的新顶台,另外所述底座上还设有微调装置,其有益效果是采用直线升降方式和螺旋上升结构,可以成多倍放大抬升力并能够承受比较大的物体重力;三向轴承机构可使新顶台与被台物体紧密接触,而不会随柱杆的旋转而旋转;便于携带,操作简单,适合广泛应用。
