Problems solved by technology

In the common lifting device, the sliding column and the fixed column are rigidly connected by the screw in the lifting device. When the sliding column is raised, the offset weight will generate an overturning moment, which will cause the screw to bend. Long-term use under this working condition will cause Make the lead screw bend, "suffocate", and produce abnormal noise

Embodiment 1

[0025] like figure 1 As shown, a hoisting device used under heavy conditions includes a frame 10 and a lifting part 20 that is movable up and down relative to the frame 10, and the frame 10 is provided with a fixed part 11 and a floating part 12. The fixed part 11 is fixedly connected to the frame 10, the floating part 12 and the fixed part 11 form a ball joint fit, and the lifting part 20 is slidably arranged on the floating part 12 along the up and down direction, and between the lifting part 20 and the floating part 12 A driving member for driving the lifting part 20 to move up and down relative to the floating part 12 is provided. The lifting part 20 of the present invention is used to connect the carrying member and drive the carrying member to realize the lifting action. When the weight on the carrying member is in a biased state for a long time, the lifting part 20 will produce a slight inclination. For this reason, the present invention uses the floating part 12 Set t...

Embodiment 2

[0030] like Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, two groups of guide rails 251 and sliders 252 are arranged symmetrically with respect to the lead screw to ensure that the force on both sides of the floating part 12 is even.

Embodiment 3

[0032] A medical examination bed, comprising the lifting device for use under partial weight conditions, and a bed surface, the bed surface is connected with the lifting part 20 . Specifically, one bed surface can be used with multiple lifting devices at the same time to ensure stable and reliable support.

Abstract

The invention belongs to the field of medical apparatuses, and particularly relates to a lifting device for a biasing-weight condition and a medical examination bed. The lifting device comprises a rack and a lifting part movably arranged up and down relative to the rack, the rack is provided with a fixed part and a floating part, the fixed part is fixedly connected with the rack, and the floatingpart and the fixed part are in spherical hinge cooperation; the lifting part is slidably arranged on the floating part in the up-down direction, and a driving member for driving the lifting part to move up and down relative to the floating part is arranged between the lifting part and the floating part. According to the lifting device, the floating part is utilized for arranging a pivot of the driving member of the lifting part on the rack to be a floating-type structure, even if the lifting part tilts, the pivot cannot cause bending moment to the driving member of the lifting part, and therefore, it is ensured that the driving member of the lifting part runs normally. Besides, the lifting device for the biasing-weight condition and the medical examination bed can also be suitable for solving the problems of bending of drive systems caused by unevenness of gaps among sliding pillars and fixed pillars due to processing, making, installing and other factors under a non-biasing-weight condition.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a lifting device and a medical examination bed used under heavy conditions. Background technique [0002] Weight lifting devices are widely used in the manufacturing industry. In our common medical device field, due to the different heights of patients, treatment or imaging equipment (that is, offset weights) is required to move up and down to a designated position for treatment or imaging. In the common lifting device, the sliding column and the fixed column are rigidly connected by the screw in the lifting device. When the sliding column is raised, the offset weight will generate an overturning moment, which will cause the screw to bend. Long-term use under this working condition will cause Make the lead screw bend, "suffocate", and produce abnormal noise. Contents of the invention [0003] The object of the present invention is to provide a lifting device and a ...
