Description

Technical Field

[0001] The present application relates to the technical field of logistics transmission equipment, and in particular, to a vertical lifting device for building logistics and a hospital logistics system. Background Art

[0002] Building logistics, especially hospital logistics, has significant characteristics: ① It is mainly composed of lightweight materials, and the weight of a single piece of cargo is not large, usually less than 5 kilograms; ② The timeliness requirement is high, and the faster the transmission speed, the better; ③ There is a "tidal phenomenon" in the quantity of freight, such as the delivery of large amounts of meals during meal times and the delivery of drugs to inpatient departments in the morning.

[0003] The diversity of building logistics systems is reflected in the size of transported items. For hospitals, smaller transport items are for sending samples and emergency medicines, larger transport items are for sending bedding, and the middle-sized transport items are mostly conventional medicines and substances. Hospital transport items are usually specialized for each profession, and it is not customary to replace small with large and unify the size. If only the logistics needs of some of the transported items are met, it will inevitably lead to the coexistence of multiple logistics systems. For example, there are now multiple transport systems coexisting in hospital logistics, such as pneumatic logistics systems, rail trolley systems, box logistics systems, and automatic guided vehicles, which leads to large hospital investment and low efficiency in item transport.

[0004] Therefore, it is necessary to develop and design a transmission device that can be compatible with the logistics needs of various transmission items in order to solve the problems existing in the existing hospital logistics system. Summary of the invention

DETAILED DESCRIPTION

[0066] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0067] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0068] According to a first aspect of the present application, a vertical lifting device for building logistics is provided.

[0069] Figure 1 FIG. 1 is a schematic diagram of a vertical lifting device according to an embodiment of the present application. Figure 1 The vertical lifting device includes a synchronous belt device 100 and a plurality of receiving devices 200.

[0070] The synchronous belt device 100 is arranged vertically, and the synchronous belt device 100 is equipped with at least one first synchronous belt 110 with a tooth surface located on the inner side and a smooth surface located on the outer side. The smooth surfaces of all the first synchronous belts 110 form a first side surface and a second side surface with a predetermined height in the vertical direction. It should be noted that the first side surface and the second side surface described in the embodiment of the present application are arranged on both sides of the first synchronous belt, and the first side surface and the second side surface are used to define the positions of the two sides of the first synchronous belt, rather than the transmission surface of the first synchronous belt. The synchronous belt portion located on the first side surface and the synchronous belt portion located on the second side surface have opposite transport directions. For example, on the first side surface, the movement direction of the first synchronous belt 110 is vertically upward, and on the second side surface, the movement direction of the first synchronous belt 110 is vertically downward; if the movement direction of the first synchronous belt 110 is vertically downward, on the second side surface, the movement direction of the first synchronous belt 110 is vertically upward.

[0071] A plurality of receiving devices 200 are arranged on the smooth surface of the first synchronous belt 110 at intervals along the vertical direction. Among them, the plurality of receiving devices 200 can be arranged only on the first side surface or only on the second side surface. In another possible implementation, the plurality of receiving devices 200 are arranged on the smooth surface of the entire first synchronous belt 110, that is, the receiving devices 200 are arranged on both the first side surface and the second side surface. The receiving devices 200 are configured with a hanging beam structure that can carry transmission loads 300 of various sizes.

[0072] In the above implementation process, the vertical lifting device uses a synchronous belt, which has a smooth surface and a tooth surface. The tooth surface structure of the synchronous belt makes the synchronous belt form a continuous lifting structure, and the smooth surface of the synchronous belt can be used to install the receiving device 200. The receiving device 200 has a mounting function, and is equipped with a hanging beam structure that can mount transmission loads 300 of various sizes. The setting of the hanging beam structure enables the vertical lifting device in this embodiment to be compatible with transmission loads of different sizes, so as to meet different transmission requirements and adapt to a wide range of scenarios.

[0073] In one implementation of the receiving device, the hanging beam structure configured by the receiving device is fixed to the spliced ​​smooth surface formed by the first synchronous belt by bolts, and the hanging beam structure is configured with a U-shaped hook or an L-shaped hook. Corresponding to the U-shaped hook or the L-shaped hook structure, the transmission load 300 is configured with a hanging structure that cooperates with the U-shaped hook or the L-shaped hook.

[0074] Figure 2 FIG. 1 is a schematic diagram of a vertical lifting device according to an embodiment of the present application. Figure 2 The synchronous belt device includes at least two first synchronous belts, and adjacent first synchronous belts are spaced a predetermined distance apart in a width direction of the first synchronous belts. Figure 2 The structure of two synchronous belts is used for explanation.

[0075] The receiving device 200 includes a first hanging beam 210 , a first group of hooks 220 and a second group of hooks 230 rigidly connected to the first hanging beam 210 .

[0076] The first hanging beam 210 extends along the width direction of the first synchronous belt surface and is fixed on the first side surface or the second side surface. In this embodiment, on the annular synchronous belt formed by the two first synchronous belts, the first hanging beams 210 are arranged on the surface of the two first synchronous belts at equal intervals in the circumferential direction.

[0077] The first set of hooks 220 and the second set of hooks 230 are separated by a predetermined distance in the direction of the width of the first synchronous belt surface, and both extend by a predetermined length in a direction perpendicular to the length of the first hanging beam 210. The first set of hooks 220 and the second set of hooks 230 are used to mount the transmission load. The hooks in the first set of hooks 220 and the second set of hooks 230 can be U-shaped hooks or L-shaped hooks, and correspondingly, a mounting structure that cooperates with the U-shaped hooks or the L-shaped hooks is provided on the transmission load.

[0078] It should be noted that the present application does not specifically limit the specific structure of the hooks in the first group of hooks 220 and the second group of hooks 230, and any structure that can achieve the hanging of the transmission load 300 falls within the protection scope of the present application.

[0079] In the above implementation process, when the transmission load is transported, the transmission load is hung on the first set of hooks 220 and the second set of hooks 230 and is located between the two first synchronous belts, and the transmission load is transmitted in the vertical direction during the synchronous movement of the two synchronous belts. Since the transmission load is carried by the two sets of hooks and is arranged at both ends of the transmission load, the structural combination of the first hanging beam 210 and the first set of hooks 220 and the second set of hooks 230 can bear a larger transmission load weight and better accommodate the carrying requirements of various transmission items.

[0080] In one possible implementation, see Figure 2 The receiving device further includes a third group of hooks 240 and a fourth group of hooks 250. The first group of hooks 220 and the third group of hooks 240 are arranged in a mirror image with respect to the horizontal center plane of the first hanging beam 210; the second group of hooks 230 and the fourth group of hooks 250 are arranged in a mirror image with respect to the horizontal center plane of the first hanging beam 210.

[0081] In the above implementation process, when located on the first side, the first group of hooks 220 and the second group of hooks 230 in a receiving device are used to carry the transmission load. When rotating to the second side with the first synchronous belt, the second group of hooks 230 and the fourth group of hooks 250 in the receiving device are used to carry the transmission load. The hanging beam structure in this structure can carry the transmission load on both the first side and the second side while being compatible with transmission loads of different sizes, thereby realizing bidirectional vertical continuous transmission of the transmission load and improving the transmission capacity.

[0082] In one possible implementation, see Figure 1 The receiving device includes a first upper hanging beam 260 and a first lower hanging beam 270. The first upper hanging beam 260 and the first lower hanging beam 270 extend a predetermined length in the direction of the width of the first synchronous belt surface, and the two are separated by a predetermined distance in the vertical direction. The first upper hanging beam 260 is rigidly connected to a fifth group of hooks 261, and the first lower hanging beam 270 is rigidly connected to a sixth group of hooks 271.

[0083] The relationship between the first upper hanging beam 260, the first lower hanging beam 270 and the transmission load is configured such that the fifth group of hooks 261 and the sixth group of hooks 271 are oriented in opposite directions, and the vertical interval between the fifth group of hooks 261 and the sixth group of hooks 271 is smaller than the height of the transmission load.

[0084] When at the first side, the first upper hanging beam 260 is used to carry the transmission load, and the sixth group of hooks 271 is used to support the lower part of the transmission load. When the receiving device moves to the second side, the first lower hanging beam 270 is used to carry the transmission load, and the fifth group of hooks 261 is used to support the lower part of the transmission load.

[0085] Figure 3It is a schematic structural diagram of a vertical lifting device according to an embodiment of the present application. Figure 4 for Figure 3 The structural diagram of the receiving device in the structure shown in FIG. Figure 3 and Figure 4 The receiving device includes a second upper hanging beam 510, a second lower hanging beam 520 and two receiving frames 530. The second upper hanging beam 510 and the second lower hanging beam 520 are arranged at intervals in the vertical direction, and both extend a predetermined length in the width direction of the smooth surface of the synchronous belt device 100. The two receiving frames 530 are arranged at a predetermined distance in the width direction of the smooth surface. When the first synchronous belt rotates to the top of the synchronous belt device, the receiving frame 530 can rotate relative to the second upper hanging beam and the second lower hanging beam, and the three do not interfere with each other during the rotation of the receiving frame. The transmission load is carried by the two receiving frames 530.

[0086] In a possible implementation, the second upper hanging beam 510 and the second lower hanging beam 520 are circular steel columns, and the second upper hanging beam 510 and the second lower hanging beam 520 are fixed to the spliced ​​smooth surface formed by the first synchronous belt 110 by bolts.

[0087] Each receiving frame 530 includes a first receiving rod 531, a second receiving rod 532 and a first connecting rod 533. The length of the first receiving rod 531 is greater than the sum of the lengths of the second receiving rod 532 and the first connecting rod 533. The first receiving rod 531 is hinged to the second lower hanging beam 520. The second receiving rod 532 is hinged to the second upper hanging beam 510 and the hinge position is located directly above the first receiving rod 531. One end of the first connecting rod 533 is hinged to the first receiving rod 531, and the other end is hinged to the second receiving rod 532.

[0088] In one embodiment, when located on the first side, the center line of the connection position of the first supporting rod 531 and the second lower hanging beam 520, the center line of the connection position of the second supporting rod 532 and the second upper hanging beam 510, the center line of the second supporting rod 532 and the first connecting rod 533, and the center line of the first supporting rod 531 form a right triangle.

[0089] The two receiving frames 530 are configured such that: when located at the first side, the second receiving rod 532 and the first connecting rod 533 are arranged horizontally, and the second receiving rod 532 and the first connecting rod 533 are both provided with a seventh set of hooks 534 for hanging and transmitting the load 300. The first receiving rod 531 is in an inclined upward state. When rotating to the top of the synchronous belt device 100 with the first synchronous belt 110, the first connecting rod 533 can rotate relative to the first receiving rod 531 and the second receiving rod 532 and prevent the two from interfering during the rotation of the first receiving rod 531 and the second receiving rod 532. And when located at the second side with the first synchronous belt 110, the first receiving rod 531, the first connecting rod 533 and the second receiving rod 532 are all in an inclined downward state.

[0090] In the above implementation process, the two receiving frames 530 only use the hooks on the two second receiving rods 532 to vertically lift or lower the transmission load 300 when they are on the first side. During the vertical movement, the gravity of the transmission load 300 is applied to the hooks, and the first connecting rod 533 will have a tendency to rotate downwardly toward the second receiving rod 532 under the gravity of the transmission load 300. The first connecting rod 533 is tilted downward toward the second receiving rod 532, and the end of the first connecting rod 533 connected to the first receiving rod 531 will exert a tendency to tilt upward on the first receiving rod 531, so the first receiving rod 531 plays a role in supporting the first connecting rod 533. At the same time, since the first connecting rod 533 has a tendency to tilt inward, it plays a role in preventing the transmission load 300 placed on the second receiving rod 532 from sliding outward, so the transmission load 300 has a higher stability in the vertical lifting process. At the same time, by adjusting the spacing of the receiving frames in the hanging beam structure, transmission loads of different sizes can be compatible in a vertical transmission channel.

[0091] In one possible implementation, Figure 5 for Figure 4 See the front view of the receiving device shown. Figure 4 The synchronous belt device 100 includes four first synchronous belts 110, which are arranged at intervals and aligned with each other to form a spliced ​​surface with a gap in the middle. There are three vertical gaps in the spliced ​​surface. Two first receiving rods 531 are hinged to the second lower hanging beams 520 at the positions of the two gaps near the two sides of the three vertical gaps.

[0092] In the above implementation process, the smooth surface of the first synchronous belt 110 forms a first side surface and a second side surface with a predetermined height in the vertical direction. If the first side surface moves vertically upward, the other side surface moves vertically downward. The receiving device can lift the transmission load 300 when the portion of the first synchronous belt 110 located on the first side surface moves vertically upward, and when the portion located on the second side surface moves vertically downward, it cannot lift the transmission load 300 and is in an unused state.

[0093] In order to further improve the lifting efficiency of the receiving device, the present application also provides a bearing frame structure on the first side and the second side, that is, the entire smooth surface of the first synchronous belt 110 can transmit the load 300.

[0094] Figure 6 Schematic diagram of a receiving device according to an embodiment of the present application. Figure 6 The receiving device 200 includes a second upper hanging beam 510 , a second lower hanging beam 520 and two receiving frames 530 .

[0095] Each receiving frame includes a third receiving rod 535 , a fourth receiving rod 536 and a second connecting rod 537 .

[0096] One end of the fourth receiving rod 536 is rotatably connected to the second lower hanging beam 520, and the other end is rotatably connected to one end of the second connecting rod 537. One end of the third receiving rod 535 is rotatably connected to the second upper hanging beam 510, and the other end is rotatably connected to a section of the second connecting rod 537. Both ends of the second connecting rod 537 are hinged to the ends of the third receiving rod 535 and the fourth receiving rod 536, respectively. The fourth receiving rod 536 is equipped with an eighth set of hooks 570, and the third receiving rod 535 is equipped with a ninth set of hooks 580;

[0097] The two supporting frames are configured as follows: when located on the first side, the third supporting rod 535 and the second connecting rod 537 are used to suspend the fourth supporting rod 536, the fourth supporting rod 536 is horizontally arranged or inclined upward relative to the horizontal direction, and the eighth group of hooks 570 of the two fourth supporting rods 536 are used to receive and transmit loads; and when rotating to the second side with the first synchronous belt, the fourth supporting rod 536 and the second connecting rod 537 are used to suspend the third supporting rod 535, the third supporting rod 535 is horizontally arranged or inclined upward relative to the horizontal direction, and the ninth group of hooks 580 of the two third supporting rods 535 are used to receive and transmit loads 300.

[0098] In a possible implementation, the third support rod 535 and the fourth support rod 536 of the support frame 530 are of equal length. When located at the first side, the center line of the connection position of the third support rod 535 and the second lower hanging beam 520 and the connection position of the fourth support rod 536 and the second upper hanging beam 510, the center line of the fourth support rod 536 and the second connecting rod 537, and the center line of the third support rod 535 form a right triangle. When located at the second side, the center line of the connection position of the third support rod 535 and the second lower hanging beam 520 and the connection position of the fourth support rod 536 and the second upper hanging beam 510, the center line of the third support rod 535 and the second connecting rod 537, and the center line of the fourth support rod 536 form a right triangle.

[0099] In the above implementation process, the third supporting rod 535 and the fourth supporting rod 536 adopt an equal length structure, and there is no special requirement for the center of gravity of the transmitted load. When carrying a larger or heavier transmission load, the vertical lifting device still has high stability.

[0100] See also Figure 7 , assuming that the length of the third receiving rod 535 is B, the connection length of the fourth receiving rod 536 and the second connecting rod 537 is C, the length of the center line between the connection position of the third receiving rod 535 and the second lower hanging beam 520 and the connection position of the fourth receiving rod 536 and the second upper hanging beam 510 is A, the length of the fourth receiving rod 536 is c1, the length of the second connecting rod 537 is c2, C=c1+c2, and the area enclosed by A, B, and C in the receiving frame 530 is S. If the third receiving rod 535 in the receiving frame 530 is horizontally arranged on the first side and the fourth receiving rod 536 is horizontally arranged after rotating to the second side, since A and S are fixed values, according to B=(S 2 -H 2 ) / 2S, B=c1. That is, the length of the third receiving rod 535 is the same as the length of the fourth receiving rod 536. This arrangement allows the third receiving rod 535 to be horizontally arranged on the first side and the fourth receiving rod 536 to be horizontally arranged behind the second side.

[0101] In a possible implementation, the second upper hanging beam 510 and the second lower hanging beam 520 are U-shaped beams; the bottom of the U-shaped beam is fixedly connected to the smooth surface. A fixing seat is provided inside the U-shaped beam, and the third receiving rod 535 and the fourth receiving rod 536 are both pivotally connected to the fixing seat through a rotating shaft.

[0102] In the above implementation process, the second upper hanging beam 510 and the second lower hanging beam 520 are U-shaped beams, and the grooves of the U-shaped beams can directly provide installation space for the fixing seat, and the third receiving rod 535 can be rotatably connected to the second lower hanging beam 520 through only one fixing seat, and the fourth receiving rod 536 can be rotatably connected to the second upper hanging beam 510 through only one fixing seat. Therefore, the connection structure has the advantages of simple structure and reduced production cost.

[0103] Figure 8 FIG. 1 is a schematic diagram of another structure of a receiving device according to an embodiment of the present application. Figure 8 , the second upper hanging beam 510 and the second lower hanging beam 520 are cylindrical cross bars. The second upper hanging beam 510 and the second lower hanging beam 520 are both provided with a rotating rod 540. The rotating rod 540 can rotate relative to the second upper hanging beam 510 / the second lower hanging beam 520. The third receiving rod 535 of each receiving frame 530 is fixedly connected to the rotating rod 540 on the second lower hanging beam 520, and the fourth receiving rod 536 is fixedly connected to the rotating rod 540 on the second upper hanging beam 510.

[0104] If the third receiving rod 535 is directly mounted on the second upper hanging beam 510 and the fourth receiving rod 536 is directly mounted on the second lower hanging beam 520, the second upper hanging beam 510 and the second lower hanging beam 520 are cylindrical cross bars, which are fixedly connected to the smooth surface of the synchronous belt. When the first synchronous belt 110 is a single synchronous belt, a part of the arc surface of the cylindrical cross bar is in fixed contact with the synchronous belt, so the cylindrical cross bar cannot be fixedly connected to the third receiving rod 535 / the fourth receiving rod 536. When the first synchronous belt 110 is a plurality of synchronous belts arranged at intervals to form a synchronous belt structure, there is no fixed connection between the gaps between adjacent synchronous belts and the cylindrical cross bar, so the gaps can be used to connect to the third receiving rod 535 / the fourth receiving rod 536. Since the setting position of the gap is limited, the setting position of the third receiving rod 535 / the fourth receiving rod 536 is also limited. In the above implementation process, there is a certain gap between the rotating rod 540 and the second upper hanging beam 510 / the second lower hanging beam 520, and the gap can reserve the installation gap between the third receiving rod 535 and the fourth receiving rod 536 and the rotating rod 540. The third receiving rod 535 / the fourth receiving rod 536 is arranged on the rotating rod 540, and the installation position is no longer limited. Therefore, the arrangement of the rotating rod 540 allows the third receiving rod 535 / the fourth receiving rod 536 to flexibly select the installation position.

[0105] It should be noted that, in the above-mentioned embodiments of the present application, there is no specific limitation on the implementation method of the hinge connection between the third supporting rod 535 and the second lower hanging beam 520, and the hinge connection between the fourth supporting rod 536 and the second upper hanging beam 510. Any hinge method that can realize the rotation of the third supporting rod 535 relative to the second lower hanging beam 520, and the rotation of the second supporting rod 532 relative to the second upper hanging beam 510 falls within the protection scope of the present application.

[0106] Fig. 9 Schematic diagram of a receiving device according to an embodiment of the present application. Fig. 9 The supporting frame 530 includes a fifth supporting rod 538 and a sixth supporting rod 539 .

[0107] One end of the sixth receiving rod 539 is rotatably connected to the second lower hanging beam 520, and the other end is rotatably connected to one end of the fifth receiving rod 538. One end of the fifth receiving rod 538 is rotatably connected to the second upper hanging beam 510, and the other end is rotatably connected to a section of the sixth receiving rod 539; the sixth receiving rod 539 is provided with a tenth set of hooks 590 and an eleventh set of hooks 591 facing opposite directions in the vertical direction.

[0108] The two supporting frames are configured as follows: when located on the first side, the fifth supporting rod 538 is used to suspend the sixth supporting rod 539, the sixth supporting rod 539 is set horizontally, and the tenth group of hooks 590 of the two sixth supporting rods 539 are vertically upward for receiving and transmitting loads; and when rotating to the second side with the first synchronous belt, the fifth supporting rod 538 is used to support the sixth supporting rod 539 obliquely upward, the sixth supporting rod 539 is set horizontally, and the eleventh group of hooks 591 of the two sixth supporting rods 539 are vertically upward for receiving and transmitting loads.

[0109] In the above implementation process, the receiving frame only uses two receiving rods to mount the transmission load, has a simple structure, is not prone to failure during the transfer process, and has the advantages of being simple and reliable.

[0110] In a more preferred embodiment, see Figure 8 , both ends of the second upper hanging beam 510 and both ends of the second lower hanging beam 520 are provided with rollers 600. Correspondingly, the vertical lifting device also includes a first track 550 and a second track 560. The first track 550 is arranged on both sides of the first side surface, and the rollers at both ends of the second upper hanging beam 510 and the rollers at both ends of the second lower hanging beam 520 located on the first side surface are both rollingly matched with the first track 550. The second track 560 is arranged on both sides of the second side surface, and the rollers at both ends of the second upper hanging beam 510 and the rollers at both ends of the second lower hanging beam 520 located on the second side surface are both rollingly matched with the second track 560.

[0111] In the above implementation process, the second upper hanging beam 510 and the second lower hanging beam 520 rotate with the first synchronous belt 110. When on the first side of the first synchronous belt 110, the second receiving rod 532 and the second connecting rod 537 are used to suspend the first receiving rod 531. The weight of the transmission load 300 and the weight of the two receiving frames 530 both act on the second upper hanging beam 510. When the load of the transmission load 300 is large, the second upper hanging beam 510 is subjected to a large downward inclined pulling force. Since the synchronous belt is a belt-shaped structure with a certain degree of flexibility, when subjected to the downward inclined pulling force, the part of the synchronous belt where the second upper hanging beam 510 is installed will tend to deviate outward from the synchronous belt movement trajectory, and then the second upper hanging beam 510 drives the synchronous belt to warp outward. If the second upper hanging beam 510 warps outward, the two first receiving rods 531 in the two receiving frames will have a tendency to tilt downward, and the transmission load 300 will be at risk of slipping. On the second side of the first synchronous belt 110, correspondingly, the second lower hanging beam 520 is tilted outward, and the two second receiving rods 532 in the two receiving frames have a tendency to tilt downward. Therefore, rollers are arranged at both ends of the second upper hanging beam 510 and the second lower hanging beam 520, and the first track 550 and the second track 560 are arranged on both sides of the synchronous belt device 100. The rollers roll in the first track 550 and the second track 560. The first track 550 and the second track 560 define the running tracks of the rollers, thereby defining the two ends of the second upper hanging beam 510 and the two ends of the second lower hanging beam 520 to tilt outward, thereby avoiding the risk of the transmission load 300 slipping.

[0112] In addition, the higher the setting height of the vertical lifting device, the greater the flexural deformation of the synchronous belt, the greater the exciting force of high-speed operation, and the more unstable the load. The hanging beam structure in the receiving device connects all the synchronous belts together, which can offset the exciting force of the asynchronous synchronous belts to a certain extent, and the setting of the pulley, the first track and the second track can further restrain the vibration of the synchronous belt. From the above analysis, it can be seen that the design of the hanging beam structure, rollers, the first track and the second track can greatly improve the stability of the vertical lifting device.

[0113] In each embodiment of the synchronous belt device 100 including the first synchronous belt 110, the synchronous belt device 100 further includes a second synchronous belt 120. Fig. 9 The second synchronous belt 120 and the first synchronous belt 110 are arranged on the same driving shaft and are arranged on both sides of the first synchronous belt 110. The receiving device 200 is fixedly connected to the smooth surface of the first synchronous belt 110 and the smooth surface of the second synchronous belt 120.

[0114] In the above implementation process, the second synchronous belt 120 and the first synchronous belt 110 are driven by the same driving device, and the receiving device 200 is fixedly connected to the first synchronous belt 110 and the second synchronous belt 120. When the first synchronous belt 110 is broken or damaged, the second synchronous belt 120 can support the receiving device 200 to continue to move. When the second synchronous belt 120 is broken or damaged, the first synchronous belt 110 can support the receiving device 200 to continue to move, that is, the first synchronous belt 110 and the second synchronous belt 120 are mutually anti-breaking safety devices to prevent the synchronous belt from breaking and causing the transmission device such as the transmission load 300 to fall.

[0115] In the vertical lifting device provided with the second synchronous belt 120, various structures of the second upper hanging beam 510, the second lower hanging beam 520 and the receiving frame 530 mentioned above can also be applied.

[0116] According to the second aspect of the present application, a hospital logistics system is also provided, which includes a vertical lifting device for building logistics of any structure as described above.

[0117] It should be noted that the present application does not make any specific limitation on the implementation method of the lifting load beam and the receiving device 200. The use of a synchronous belt in the present application is only a preferred embodiment. The use of flexible alternatives such as chains and steel cables to implement the present application should be included in the protection scope of the present application.
