The electric shifter does not need to be adjusted towards the sickbed 15 as in the prior art, and the supporting beams 1-2 enter under the sickbed 15. Similarly, when a patient is suspended from the wheelchair 16, the wheelchair 16 may be located beside the two support beams 1-2 or the electric shifter, and does not necessarily have to be located between the two support beams 1-2. The invention utilizes the balance of the gravity center of the operator, and can ensure that the electric shifter can not topple over when the upright post 2 rotates. As shown in fig. 8, the controller 10 and the handrail 9 rotate along with the upright post 2, and when an operator stands on the people standing area 1-1-1, the controller 10 and the handrail 9 are still facing the operator, so that the operation is not inconvenient.

The specific implementation manner of the rotatable connection between the upright 2 and the base 1-1 can be various, and the invention is preferably as follows: the base plate 1 comprises upright post mounting sleeves 1-3 and upright post limiting discs 1-5, the base 1-1 is of a hollow structure, the base 1-1 comprises a base top plate 1-1-2, the upright post mounting sleeves 1-3 are connected with the base top plate 1-1-2, the upright posts 2 are inserted into the upright post mounting sleeves 1-3 and matched with the upright post mounting sleeves 1-3, the bottom ends of the upright posts 2 abut against the base top plate 1-1-2, the upright post limiting discs 1-5 are located in the base 1-1, and the upright post limiting discs 1-5 are attached to the base top plate 1-1-2 and connected with the upright posts 2.

The rotation angle of the column 2 only needs to be less than 180 °, so the column rotation driving device 11 can achieve the effect and has a simple structure.

The specific structure of the column rotation control device 12 can be various, and the present invention is preferably as shown in fig. 6: the upright post rotation control device 12 comprises a sound generating device, an unlocking device and two position sensors 12-1; when the upright post 2 rotates to enable the center of the suspension frame 4 to move outwards to be close to and correspond to the edge position of the chassis 1, the upright post driving post 11-2 corresponds to the position of the position sensor 12-1, the position sensor 12-1 locks the first electric telescopic rod 11-1 through a signal and starts the sound generating device, and the unlocking device can unlock the first electric telescopic rod 11-1. The unlocking means and the sound emitting means may be provided on the controller 10. The sling 14 is suspended from the sling 4, and the patient lies on the sling 14 with his own centre of gravity substantially on the axis of the sling 14. Therefore, when the center of the suspension frame 4 moves outwards to be close to and correspond to the edge position of the chassis 1, the sounding device prompts an operator to stand on the standing person area 1-1-1 to balance the gravity center, and therefore the operation is safe. After an operator stands on the person standing area 1-1-1, the unlocking device is operated to lock the first electric telescopic rod 11-1 in a contact mode, and then the first electric telescopic rod 11-1 can continue to drive the upright post 2 to rotate. Although the gravity center of the patient rotates to the outside of the chassis 1, the electric shifter cannot topple due to the balance effect of the self gravity of the electric shifter and the gravity of the operator.

The connection mode of the upper crossbeam 3 and the upright post 2 and the specific structure of the upper crossbeam lifting device 6 can be various, and the invention is preferably as follows: the upper beam 3 is connected with the upright post 2 through two beam guide devices 5, each beam guide device 5 comprises a beam guide rod 5-1 and a beam guide sleeve 5-2 sleeved on the beam guide rod 5-1, the two beam guide devices 5 are vertically arranged at intervals, the beam guide rod 5-1 is connected with the upright post 2, and the upper beam 3 is connected with the beam guide sleeve 5-2; the upper crossbeam lifting device 6 comprises a second electric telescopic rod 6-1, a first pulley 6-2, a second pulley 6-3 and a pull rope 6-4, the second electric telescopic rod 6-1 is vertically arranged in the upright post 2, the first pulley 6-2 is positioned right above the second electric telescopic rod 6-1, the second pulley 6-3 is positioned right above the upper crossbeam 3, the pull rope 6-4 bypasses the first pulley 6-2 and the second pulley 6-3, and two ends of the pull rope 6-4 are respectively connected with the second electric telescopic rod 6-1 and the upper crossbeam 3.

The upper cross beam 3 of the invention is vertical up and down without swinging, thus avoiding the unnecessary change of the angle of the patient in the lifting process of the upper cross beam 3. The upper beam 3 rises by means of the shortening of the second electric telescopic rod 6-1 to drive the pull rope 6-4 to pull. When the upper cross beam 3 descends, the second electric telescopic rod 6-1 extends, and the upper cross beam 3 descends by means of self gravity. The pull ropes 6-4 not only pull the upper beam 3, but also have the function of avoiding improving the stress of the beam guide device 5, greatly reduce the bending moment applied to the beam guide device 5, and are beneficial to ensuring the straightness of the beam guide device 5 after long-term use. Meanwhile, the pull rope 6-4 is positioned above the upper cross beam 3, so that the space below the upper cross beam 3 is not occupied, and the legs of a patient can be prevented from being touched.

Comparing fig. 2 and fig. 8, as shown in fig. 2, the suspension frame 4 is not rotatable, and when the patient is suspended, the suspension frame and the suspension belt 14 cannot be in the same direction as the sickbed 15, and the patient can be suspended only by manually adjusting the direction of the patient; as shown in fig. 8, the suspension rack 4 can be rotated, so that the patient direction does not need to be manually adjusted, and the suspension clamp 4 can be rotated to enable the suspension belt 14 to be in the same direction with the patient and the sickbed 15, so that the patient can be directly suspended. The suspension drive device 7 has the same principle as the column rotation drive device 11, and will not be described in detail here.

When the patient is lifted from the sickbed 15, the patient is in a lying posture; and when the patient is suspended from the wheelchair 16, the patient is in a sitting position. I.e. if the patient is displaced from the bed 15 to the wheelchair 16, the patient can preferably change from a lying position to a sitting position; otherwise, the patient is preferably able to change from a sitting position to a lying position.
