Background technique

Electric lift is a device used in hospitals to move patients with reduced mobility, such as safe transfer of paralyzed, injured legs and feet between beds, wheelchairs, seats, and toilets.

As shown in Figure 1, the existing electric lift usually includes a chassis, a column, an upper beam, an upper beam lifting device and a suspension frame. The chassis includes a base and two support beams connected to the front end of the base. The bottom of the base and the support beam are Rollers are provided, the column is connected with the base, the upper beam is connected with the column, the upper beam lifting device can drive the upper beam to rise and fall, and the suspension frame is connected with the upper beam. Electric lifts are used with slings. Take moving a patient from a hospital bed to a wheelchair as an example, first lay the sling flat on the hospital bed, then manually move the patient to the sling, then hang the sling on the suspension frame, and then raise the upper beam, Then move the electric lift until the patient is aligned with the wheelchair, lower the upper beam, and place the patient and the sling on the wheelchair.

CN109431719A discloses an electric lift machine, the structure of which is similar to the above electric lift machine, and the working mode is basically the same as that of the above electric lift machine.

The disadvantages of the existing electric lift machine are: 1. As shown in Figure 2, when the patient is hoisted from the hospital bed, the existing electric lift machine needs to face the hospital bed, and the support beam enters under the hospital bed, so that the suspension frame and the suspension belt can be located on the hospital bed. directly above, thereby suspending the patient. In hospital wards, the gap between the bed and the bed is usually not large, and there are many items placed under the bed. It is very inconvenient to adjust the position of the electric lift, and it often takes a lot of time and effort to adjust to the above position. As shown in Figure 3, lifting the patient from the wheelchair is similar, only if the wheelchair is located between the two support beams, not if it is next to the electric lift. 2. The suspension frame cannot be rotated. In the state shown in Figure 2, the patient on the electric lift is facing the width of the bed, while lying on the bed requires the patient to face the length of the bed. Therefore, it is necessary to manually adjust the patient's position when hoisting. inconvenient. 3. The lifting method of the upper beam of most existing electric lifts is that the electric telescopic rod drives the upper beam to swing as shown in Figure 1, which will cause the suspension frame to swing and cause the patient's angle to change unnecessarily. 4. The angle of the suspension frame cannot be adjusted; when the patient is transferred between the hospital bed and the wheelchair, it is necessary to switch between the sleeping position and the sitting position, and the angle of the suspension frame cannot be adjusted, which makes the posture switching inconvenient. 5.

Detailed ways

The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

As shown in Figures 4 to 7: the electric lift includes a chassis 1, a column 2, an upper beam 3, an upper beam lifting device 6 and a suspension frame 4. The chassis 1 includes a base 1-1 and is connected to the front end of the base 1-1. The two supporting beams 1-2, the column 2 is connected with the base 1-1, the upper beam 3 is connected with the column 2, the upper beam lifting device 6 can drive the upper beam 3 to rise and fall, and the suspension frame 4 is connected with the upper beam 3; also includes The column rotation driving device 11 and the column rotation control device 12, the column 2 can rotate around its own axis, the column rotation driving device 11 can drive the column 2 to rotate, and the two ends of the base 1-1 have standing areas 1-1-1; The rotation control device 12 can prompt the operator to stand in the standing area 1-1-1, so as to avoid the over-shift of the center of gravity of the electric lift machine caused by the rotation of the upright 2, which may lead to overturning.

In addition to the above structure, the electric lift of the present invention should also be the same as the existing electric lift, and conventionally have parts such as handrail 9, controller 10, rollers 1-4 and batteries. The operator can move the electric lift manually by holding the handrail 9. The controller 10 is used to control the operation of each electric component, and various control components such as control switches and buttons are provided on the controller 10 . Both the handrail 9 and the controller 10 are connected to the upright column 2 . The rollers 1-4 are connected to the base 1-1 and the support beam 1-2 to facilitate the movement of the electric lift. The battery is arranged in the base 1-1 to supply power to each electrical device.

As shown in FIG. 8, the present invention is moved to the side of the hospital bed 15, and the suspending frame 4 and the suspending belt 14 can be positioned directly above the hospital bed 15 by rotating the upright column 2, thereby suspending the patient. There is no need to adjust the electric lift towards the bed 15 as in the prior art, and the support beams 1-2 go under the bed 15. Likewise, when the patient is hoisted on the wheelchair 16, the wheelchair 16 may be located beside the two support beams 1-2 or the electric lift machine, and does not necessarily need to be located between the two support beams 1-2. The present invention utilizes the operator to balance the center of gravity, which can ensure that the electric lift will not fall over when the upright column 2 rotates. As shown in FIG. 8 , the controller 10 and the armrest 9 rotate with the upright column 2. When the operator stands on the standing area 1-1-1, the controller 10 and the armrest 9 still face the operator, which will not cause inconvenience to the operation. .

There are various specific implementations for the rotatable connection between the column 2 and the base 1-1. The present invention is preferably as follows: the chassis 1 includes a column mounting sleeve 1-3 and a column limit plate 1-5, and the base 1-1 is a hollow structure. The base 1-1 includes the base top plate 1-1-2, the column installation sleeve 1-3 is connected with the base top plate 1-1-2, the column 2 is inserted into the column installation sleeve 1-3 and cooperates with the column installation sleeve 1-3, the column 2 The bottom end abuts on the base top plate 1-1-2, the column limit plate 1-5 is located in the base 1-1, and the column limit plate 1-5 is attached to the base top plate 1-1-2 and connected to the column 2. The upright post 2 is inserted into the upright post installation sleeve 1-3 and cooperates with the upright post installation sleeve 1-3 so that the upright post 2 can be rotated. The distance between the column limit plate 1-5 and the bottom surface of the column 2 should match the thickness of the base top plate 1-1-2, and a gasket can be used between the two to ensure the distance. The column limit plate 1-5 and the column 2 Fastener connections are available.

The specific structure of the column rotation driving device 11 can be various, and the present invention is preferably as shown in FIG. 6 : the column rotation driving device 11 is located in the base 1-1, and the column rotation driving device 11 includes a column driving column 11-2 and a first electric motor. The telescopic rod 11-1, the column drive column 11-2 is connected with the column limit plate 1-5, the center of the column drive column 11-2 is separated from the center of the column 2, and the first electric telescopic rod 11-1 is connected to the base 1-1 It is hinged with the column drive column 11-2. The rotation angle of the column 2 only needs to be less than 180°, so the above-mentioned 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 column rotation control device 12 includes a sounding device, an unlocking device and two position sensors 12-1; 4. When the center moves out to the position corresponding to the edge of the chassis 1, the column drive column 11-2 corresponds to the position of the position sensor 12-1. The signal of the position sensor 12-1 locks the first electric telescopic rod 11-1 and activates the sounding device to unlock the The device can unlock the first electric telescopic rod 11-1. The unlocking device and the sounding device may be provided on the controller 10 . The suspension belt 14 is hung on the suspension frame 4 , and the patient is lying on the suspension belt 14 , and the patient's own center of gravity is basically located on the axis of the suspension belt 14 . Therefore, when the center of the suspension frame 4 is moved out to the position corresponding to the edge of the chassis 1, the sounding device will prompt the operator to stand on the standing area 1-1-1 to balance the center of gravity. After the operator stands on the standing area 1-1-1, the operator operates the unlocking device to contact the locking of the first electric telescopic rod 11-1, and then the first electric telescopic rod 11-1 can continue to drive the column 2 to rotate. Although the patient's center of gravity rotates out of the chassis 1, the electric lift will not tip over due to the balance between its own gravity and the operator's gravity.

The connection mode of the upper beam 3 and the column 2 and the specific structure of the upper beam lifting device 6 can be various, and the present invention is preferably as follows: the upper beam 3 is connected with the column 2 through two beam guides 5, and the beam guide 5 includes a beam guide rod. 5-1 and the beam guide sleeve 5-2 set on the beam guide rod 5-1, the two beam guide devices 5 are arranged vertically and at intervals, the beam guide rod 5-1 is connected with the column 2, and the upper beam 3 is guided with the beam The sleeve 5-2 is connected; the upper beam lifting device 6 includes a second electric telescopic rod 6-1, a first pulley 6-2, a second pulley 6-3 and a pulling rope 6-4, and the second electric telescopic rod 6-1 is vertical Straightly arranged in the column 2, the first pulley 6-2 is located directly above the second electric telescopic rod 6-1, the second pulley 6-3 is located directly above the upper beam 3, and the pulling rope 6-4 bypasses the first pulley 6- 2 and the second pulley 6-3, the two ends of the pulling rope 6-4 are respectively connected with the second electric telescopic rod 6-1 and the upper beam 3.

In the present invention, the upper beam 3 is vertically up and down without swinging, which can avoid unnecessary changes in the patient's angle during the lifting and lowering of the upper beam 3 . The rise of the upper beam 3 relies on the shortening of the second electric telescopic rod 6-1 to drive the pull rope 6-4 to pull. When the upper beam 3 is lowered, the second electric telescopic rod 6-1 is extended, and the upper beam 3 is lowered by its own gravity. In addition to pulling the upper beam 3, the pull rope 6-4 also has the function of avoiding improving the force of the beam guiding device 5, greatly reducing the bending moment of the beam guiding device 5, which is beneficial to the long-term use of the beam guiding device 5 and still ensuring the straightness. At the same time, the pulling rope 6-4 is located above the upper beam 3, does not occupy the space below the upper beam 3, and can avoid touching the patient's leg.

In order to adjust the patient's direction conveniently, the electric lift machine includes a suspension frame driving device 7, and the suspension frame driving device 7 includes a third electric telescopic rod 7-4, a suspension frame connecting rod 7-1, and a suspension frame upper limit plate 7 -2.

The suspension frame driving device 7 can drive the suspension frame 4 to rotate. Comparing Fig. 2 and Fig. 8, as shown in Fig. 2, the suspension frame 4 cannot be rotated. When hoisting, the suspension frame and the suspension belt 14 cannot be in the same direction as the hospital bed 15, and the patient needs to be manually adjusted to suspend the patient; as shown in Fig. 8 , the suspension frame 4 can be rotated, so there is no need to manually adjust the direction of the patient, and the suspension clip 4 can be rotated so that the suspension belt 14 is in the same direction as the patient and the bed 15, so that the patient can be directly suspended. The principle of the suspension frame driving device 7 is the same as that of the column rotation driving device 11 , which will not be repeated here.

When the patient is suspended from the hospital bed 15, the patient is in a lying position; and when the patient is suspended from the wheelchair 16, the patient is in a sitting position. That is, if the patient is moved from the hospital bed 15 to the wheelchair 16, the patient can preferably change from the lying position to the sitting position; otherwise, the patient can preferably change from the sitting position to the lying position. In order to realize the above transformation, the suspension frame 4 of the present invention comprises an upper suspension frame 4-1, a lower suspension frame 4-2 and a fourth electric telescopic rod 4-3, the upper suspension frame 4-1 is connected with the upper beam 3, and the suspension The lower hanging frame 4-2 is hinged with the upper hanging frame 4-1, the fourth electric telescopic rod 4-3 is hinged with the upper hanging frame 4-1 and the lower hanging frame 4-2, and the fourth electric push rod can drive the lower hanging frame 4-2. Rack 4-2 swings. The angle of the patient on the suspension belt 14 can be adjusted by swinging the lower suspension frame 4-2, so as to substantially realize the angle of the patient, that is, the attitude change.

In order to facilitate the storage of the electric lift, the present invention is further improved as follows: the electric lift includes a fifth electric telescopic rod 8 and a sixth electric telescopic rod 13, the support beams 1-2 and the upper beam 3 are telescopic beams, the fifth The electric telescopic rods 8 are arranged in one-to-one correspondence with the supporting beams 1-2, the fifth electric telescopic rod 8 is connected in parallel with the corresponding supporting beams 1-2, and the fifth electric telescopic rods 8 can drive the corresponding supporting beams 1-2 to expand and contract, The sixth electric telescopic rod 13 is connected with the upper beam, and the sixth electric telescopic rod 13 can drive the upper beam 3 to expand and contract. The support beam 1-2 and the upper beam 3 are extended during use, and the support beam 1-2 and the upper beam 3 are shortened during storage to save storage space.
