Description

Technical Field

[0001] The invention belongs to the technical field of indoor medical logistics transportation, and in particular relates to an indoor medical logistics transportation robot. Background Art

[0002] Due to the limitations of the usage methods of indoor medical logistics handling robots, they will face a variety of usage situations when carrying medical logistics, but not limited to the one proposed below. More specifically, especially for medical logistics, there are different types of items, and the specifications of the items are also different. Since the size of the part of the handling robot that supports medical logistics items is fixed, it can carry smaller items, but it cannot fully support larger items, which can easily cause the center to be unstable, and then cause rollover, and in severe cases, damage the items.

[0003] In addition, due to the limitation that handling robots are mainly used for medical logistics handling work indoors, conventional handling robots mainly rely on gravity to confine items to their supporting parts. Due to the large flow of people inside the hospital, when carrying items, they are very likely to stop suddenly or cause accidental collisions due to obstacles in front, causing items to fall from the handling robots. Therefore, it will not only have a certain impact on the transportation of items, but also easily cause accidental damage.

[0004] Combining the above two points of view, it is found that it is difficult to avoid the above problems at the same time when the existing indoor medical logistics handling robots on the market are in use, and even if they can be solved, they need to be connected to external devices, which makes it impossible to achieve the desired effect. Therefore, we propose an indoor medical logistics handling robot that can support and transport medical logistics items of different specifications and limit the position of items when in use.

[0014] By adopting the above technical solution, an extension component is set up, and the driving gear is engaged with the teeth, so that the driving wheel can drive the extension frame to move, so that the extension frame can drive the extension plate in and out or move out of the interior of the fixed plate, thereby expanding the supporting area and achieving the effect of flexible use.

[0015] The present invention is further configured as follows: the stabilizing assembly includes a U-shaped frame, the U-shaped frame is bolted to the surface of the extension plate, the bottom of the U-shaped frame is bolted to the telescopic member, the bottom of the telescopic member is bolted to a mounting plate, the bottom of the mounting plate is bolted to a stabilizing wheel, the surface of the telescopic member is sleeved with a stabilizing spring, and the top and bottom of the stabilizing spring are bolted to the connecting plate and the U-shaped frame respectively.

[0016] By adopting the above technical solution, by setting up a stabilizing component, the stabilizing wheel can be in contact with the ground when the extension component is extended, so that the contact area between the main body of the transport robot and the ground can be increased. At the same time, when the ground is uneven, the stabilizing wheel can always be in contact with the ground under the action of the telescopic part and the stabilizing spring, thereby ensuring the stability of the main body of the transport robot during movement.

Under the connection of the first connecting tube, the second connecting tube and the third connecting tube, the cavities in different areas can be evacuated. Therefore, on the one hand, it can avoid the disadvantages of evacuating all the internal cavities of the frame body, which causes reduced exhaust efficiency and long exhaust time. On the other hand, multiple areas are isolated and sealed from each other, and certain areas are selected for adsorption and fixation, which better avoids the problem of increased energy consumption.

[0025] The present invention is further configured as follows: the tops of the first annular baffle plate and the second annular baffle plate are in close contact with the bottom of the adsorption cover plate, a support plate is welded to the inner wall of the frame body, the adsorption cover plate is bolted to the frame body through the support plate, a seal is bonded to the bottom of the adsorption cover plate, and the seal is in close contact with the support plate.

On the other hand, multiple areas are isolated and sealed from each other, and certain areas are selected for adsorption and fixation, which better avoids the problem of increased energy consumption. Under the action of the branch pipe 36, the vacuum state in the frame body 31 can be quickly released, which facilitates the separation of the items from the adsorption cover 32.

[0055] like Fig.10As shown, the partition 34 includes a first annular partition 341 and a second annular partition 342, the first annular partition 341 and the second annular partition 342 are welded to the inside of the frame body 31, and the diameter of the first annular partition 341 is smaller than that of the second annular partition 342, the front side of the first annular partition 341 is connected to a first connecting pipe 343, the front side of the first connecting pipe 343 passes through the inside of the second annular partition 342, the front side of the second annular partition 342 is connected to a second connecting pipe 344, the right side of the inner wall of the frame body 31 is connected to a third connecting pipe 345, the front sides of the first connecting pipe 343, the second connecting pipe 344 and the third connecting pipe 345 are all connected to the multi-channel The first connecting tube 343, the second connecting tube 344 and the third connecting tube 345 are connected to each other, so that the interior of the frame body 31 can be divided into a plurality of adsorption areas, and the areas can be connected to the corresponding adsorption holes 33. Under the connection of the first connecting tube 343, the second connecting tube 344 and the third connecting tube 345, the cavities in different areas can be evacuated. Therefore, on the one hand, it can avoid the disadvantages of evacuating all the internal cavities of the frame body 31, which will reduce the exhaust efficiency and prolong the exhaust time. On the other hand, the multiple areas are isolated and sealed from each other, and some areas are selected for adsorption and fixation, which can better avoid the problem of increased energy consumption.

[0056] like Fig. 9 and Fig.10 As shown, the tops of the first annular baffle 341 and the second annular baffle 342 are in close contact with the bottom of the adsorption cover plate 32, a support plate 5 is welded to the inner wall of the frame body 31, the adsorption cover plate 32 is bolted to the frame body 31 through the support plate 5, a seal 6 is bonded to the bottom of the adsorption cover plate 32, and the seal 6 is in close contact with the support plate 5. By setting the support plate 5, it is convenient to fix the adsorption cover plate 32, and by setting the seal 6, the connection between the adsorption cover plate 32 and the frame body 31 can be sealed to avoid leakage.

[0057] Brief description of the use process: When supporting items, the frame body 31 is connected to the handling robot body 1 through the external lifting structure, so that the frame body 31 can drive the adsorption cover plate 32 to contact the bottom of the item, and select the corresponding adsorption area according to the specifications of the item. When adsorbing smaller items, the air in the cavity of the first annular partition plate 341 can be extracted through the vacuum pump 38 through the exhaust pipe 37, the multi-channel valve 35 and the first connecting pipe 343, and the item is adsorbed on the adsorption cover plate 32 under the action of the adsorption hole 33. When the item is larger or bulky, repeat the above steps. The second connecting tube 344, the second annular partition 342 and the third connecting tube 345 are selected to gradually expand the adsorption area. During the transportation process, instead of relying solely on gravity to fix the items, this can prevent the items from falling due to sudden stops due to obstacles in front or due to other people accidentally touching the items, thereby ensuring the safety of medical logistics transportation. When the adsorption needs to be released, the vacuum pump 38 can be stopped and the branch pipe 36 can be opened to quickly release the vacuum state in the frame body 31, making it easier to separate the items from the adsorption cover 32.
