Detailed Description

In order to make the objects, technical solutions and advantages of the present disclosure more clear, the present disclosure is further described in detail by referring to the following examples. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In an exemplary embodiment, and with particular reference to fig. 1-3, a lift support apparatus of the present disclosure for supporting a first object, a support platform, such as an upper tie plate 1, the upper tie plate 1 having a support surface, such as an upper surface of the upper tie plate 1, the upper surface of the upper tie plate 1 being substantially planar in shape, the shape defining a plane, i.e., the upper surface of the upper tie plate 1 lies in a first plane, the upper surface of the upper tie plate 1 being adapted to carry the first object to be supported; of course, the plate-like support table is merely exemplary, as long as any form of support table having a substantially planar support surface is optional, e.g., the upper surface of the support table is substantially planar for placement of the first object, while the lower surface may be arcuate or other complex shape. A base, such as a lower tie plate 5, for supporting the support means; other forms of base are also optional, such as semi-circular, or fixed by spikes inserted into the ground. The actuating device, such as the lifting motor 8, the lifting motor 8 can extend and retract linearly along the first direction, and the movement of the extending and retracting motor 8 drives the upper connecting plate 1 to move away from or close to the lower connecting plate 5; other forms of actuating means are also optional, such as hydraulic pumps, or transmission forms such as chains, racks, etc. according to the actual stroke, as long as the upper link plate 1 can be driven to move linearly away from or close to the lower link plate 5 in the first direction, i.e. to move telescopically. Wherein, the included angle between the first plane and the first direction is more than 0 degree and less than 90 degrees.

The direction of the telescopic movement of the actuator means, i.e. the first direction, is important, the first direction being neither parallel nor perpendicular to the first plane, and the angle being greater than 0 degrees and smaller than 90 degrees. Thus, when the brake moves the support table away from or close to the base, the motion can be decomposed into a motion parallel to the first plane and a motion perpendicular to the first plane (i.e., a direction along the normal of the first plane), so that the motion can be closer to and/or farther away from the target object in two dimensions. Referring particularly to fig. 1-2, the upper surface of the upper tie sheet 1 is located in a horizontal plane, and the direction perpendicular to the upper surface of the upper tie sheet 1 is the direction of gravity. Illustratively, the target object is at the left side of the support assembly depicted in FIGS. 1-2 and is at a height approximately the same as the height of the upper surface of the upper tie plate 1 when the support assembly is raised in FIG. 1. Like this, under elevator motor's drive, go up the in-process that even board 1 risees, on the one hand, prolong the direction of gravity and be close the target object, on the other hand, prolong the horizontal direction and also be close the target object, under simple linear motion drives, strutting arrangement drives first object and has been close the target object in two dimensions. It is therefore important that the first plane and the first direction enclose an angle of more than 0 degrees and less than 90 degrees. In an exemplary embodiment, the angle between the first plane and the first direction is greater than 30 degrees and less than 85 degrees, or greater than 60 degrees and less than 80 degrees, or greater than 30 degrees and less than 70 degrees. The included angle can be calculated, and after the distance that the upper connecting plate 1 needs to move in the horizontal direction and the distance that the upper connecting plate needs to move in the vertical direction are obtained, the included angle can be easily calculated according to the distance.

In an exemplary embodiment, and referring particularly to fig. 1-2, lift motor 8 is coupled to upper link plate 1 at a first point, upper hinge 7, and lift motor 8 is coupled to lower link plate 5 at a second point, lower hinge 9, with upper hinge 7 and lower hinge 9 being positioned in a line in a first direction of motion of lift motor 8, and the telescoping motion of lift motor 8 varies the distance between upper hinge 7 and lower hinge 9 to move upper link plate 1 away from or toward lower link plate 5. The hinged connection is exemplary, and other mechanical fastening means are optional, such as welding, riveting, and the like.

In an exemplary embodiment, and with particular reference to fig. 1-4, further includes at least one support sleeve disposed about lift motor 8 for movement with the telescoping movement of lift motor 8. The supporting sleeve is used as an appearance piece, so that the exposure of the lifting motor 8 is avoided, and meanwhile, the safety is also ensured. The support cover includes: the first supporting sleeve, namely the inner supporting sleeve 2, is connected with the upper connecting plate 1 and moves along with the upper connecting plate 1; the second supporting sleeve, namely the middle supporting sleeve 3, is sleeved with the inner supporting sleeve 2 and arranged to surround the inner supporting sleeve 2; the supporting device also comprises a fixed sleeve 4 which is connected with the lower connecting plate 5 and is sleeved with the middle supporting sleeve 3 to surround the middle supporting sleeve 3. The fixed sleeve 4 does not move along with the telescopic motion of the lifting motor 8, but also surrounds the lifting motor 8, so that the exposure of the lifting motor 8 is avoided. The number of the supporting sleeves is arbitrary and depends on the lifting amplitude and the design of the appearance of the lifting device.

When the elevator motor moves to a first position, such as the raised position shown in fig. 1, a first portion of the inner support sleeve 2 is located in the middle support sleeve 3 and a third portion of the middle support sleeve 3 is located in the fixed sleeve 4; when the lifting motor 8 is moved to a second position, for example the lowered position shown in fig. 2, the second portion of the inner support sleeve 2 is located in the middle support sleeve 3 and the fourth portion of the middle support sleeve 3 is located in the fixed sleeve 4, obviously the first portion is smaller than the second portion and the third portion is smaller than the fourth portion.

In the exemplary embodiment of fig. 1-4, the support sleeve located above is smaller and the support sleeve located below is larger and surrounds the support sleeve above. Alternatively, the upper support sleeve may be larger and the lower support sleeve smaller, with the upper support sleeve surrounding the lower support sleeve.

In an exemplary embodiment, see in particular fig. 4, the connection between the inner support sleeve 2 and the intermediate support sleeve 3, and/or between the intermediate support sleeve 3 and the fixed sleeve 4, is by means of linear guides extending in a first direction and/or support wheels rolling in the first direction. I.e. between the inner support sleeve 2 and the middle support sleeve 3, and/or between the middle support sleeve 3 and the fixed sleeve 4, are supported by linear guide rails and rollers, and are controlled by linear brakes. Illustratively, the inner support sleeve 2, the middle support sleeve 3 and the fixed sleeve 4 are substantially quadrangular in shape, and linear guides are located between respective edges of a first side (i.e., an upper side in fig. 4) of the inner support sleeve 2, the middle support sleeve 3 and the fixed sleeve 4, specifically, one outer linear guide 10 is located between the middle support sleeve 3 and the fixed sleeve 4, and one inner linear guide 10 is located between the inner support sleeve 2 and the middle support sleeve 3. And the support wheels are located between the corresponding sides of the other side (i.e., the lower side in fig. 4) of the opposite side of the first side of the inner support sleeve 2, the middle support sleeve 3 and the fixed sleeve 4, specifically, the two rolling support wheels 11 and the rolling support wheel seat 12 are located between the middle support sleeve 3 and the fixed sleeve 4, and the two rolling support wheels 11 and the rolling support wheel seat 12 are located between the inner support sleeve 2 and the middle support sleeve 3. The number and position of the linear guide rails and the support wheels are optional, for example, one support wheel is arranged on the upper side, two linear guide rails are arranged on the lower side, or one support wheel is added on each of the left side and the right side.

In an exemplary embodiment, referring particularly to fig. 1, a manual release shaft 6 is also included, the manual release shaft 6 manually controlling the movement of the upper tie plate 1 away from or toward the lower tie plate 5 in the event of a failure of the lift motor 8. In actual use, there is a failure of lift motor 8, in which case manual release shaft 6 can be used to control the movement of upper link plate 1, which is useful particularly in restoring the reset condition. For example, the lowered state shown in fig. 2 is a reset state, and when the upper link plate 1 is raised to the raised state shown in fig. 1, the lift motor 8 is deactivated, and at this time, the manual release shaft 6 can be used to lower the upper link plate 1 to the reset state, thereby facilitating the first object to be separated from the upper link plate 1.

In one exemplary embodiment, further comprising: and the second direction movement device controls the upper surface of the upper connecting plate 1 to move along a second direction, and the second direction is vertical to the normal of the first plane. In the embodiment shown in fig. 1-3, the first plane is a horizontal plane and the second direction is a horizontal direction. The second direction moving means (not shown) is used to control the upper surface of the upper link plate 1 to move further in the horizontal direction, although the upper surface of the upper link plate 1 is already closer to the target object in the horizontal direction during the extension movement of the lift motor 8 in the first direction, the approach may still be insufficient, and the upper surface of the upper link plate 1 is still required to approach the target object further, even to extend into the inside of the target object.

In one exemplary embodiment, and with particular reference to fig. 1-3, there is provided a medical apparatus comprising: a medical examination apparatus having an accommodation space; a support device; when the lifting motor 8 moves to drive the upper connecting plate 1 to move away from or close to the lower connecting plate 5, the upper connecting plate 1 correspondingly moves close to or away from the accommodating space in the second direction, and the second direction is perpendicular to the normal of the first plane. In the exemplary embodiment, the medical examination apparatus is the target object, and is located at the left side in fig. 1, the upper surface of the upper link plate 1 is located at the horizontal plane, and the telescopic motion of the lifting motor 8 in the supporting device drives the upper link plate 1 to approach the medical examination apparatus. This approach is not only in the height direction but also in the horizontal direction. For example, the examination device may be a CT or MRI, in which case, the first object is a patient or an animal to be examined, when the first object is moved to the highest position by the upper connecting plate 1, the patient or the animal to be examined needs to be further fed into the examination cavity of the CT or MRI, and the upper surface of the upper connecting plate can be further moved along the horizontal direction by the second direction moving device, so as to drive the patient or the animal to be examined into the examination cavity of the CT or MRI. In the embodiment, the supporting device is used as a diagnosis bed, and the horizontal stroke can be compensated while the supporting device is lifted, so that the efficiency is improved, the motor power is reduced, the movement noise is reduced, the cost is reduced, and the service life is prolonged.

According to the scheme provided by the disclosure, the inclined pushing and multi-sleeve supporting structure with different angles can be adopted according to different requirements, the structure is compact and simple, parts are easy to machine and form, the manufacturing is simple, the cost is low, the bearing capacity is improved, the stability is improved, and the movement noise is reduced.
