Description

Technical Field

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

[0002] Building logistics, especially hospital logistics, has remarkable characteristics: ① mainly light substances, with the weight of a single piece of goods being small, usually less than 5 kilograms; ② high time limit requirements, and the faster the transmission speed, the better; ③ there is a "tidal phenomenon" in the freight volume, such as the distribution of a large number of meals during meal times and the distribution of drugs in the inpatient department in the morning.

[0003] The diversity of building logistics systems is reflected in the size of the transported items. For hospitals, the smaller transported items are sent inspection materials and emergency drugs, the larger transported items are sent bedding, and the medium-sized transported items are mostly conventional drugs and substances. Hospital transported items are usually specialized for each profession, and the practice of substituting large for small and having a unified size is not accepted in the habit. If only meeting the logistics needs of some of the transported items, it will inevitably lead to a situation where multiple logistics systems coexist. For example, there are currently multiple transmission systems coexisting in hospital logistics, such as pneumatic logistics systems, rail car systems, box-type logistics systems, automated guided vehicles, etc., which in turn lead to high hospital investment and low item transmission efficiency.

[0004] Therefore, it is necessary to research and develop a transmission device that can be compatible with the logistics needs of multiple transported items to solve the problems existing in the current hospital logistics system. Summary of the Invention

Detailed implementation manners

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0040] 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 claimed, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.

[0041] According to the first aspect of the present application, a vertical lifting device for building logistics is provided.

[0042] Figure 1 As shown in the structural schematic diagram of a vertical lifting device according to an embodiment of the present application. Refer to Figure 1 , the vertical lifting device includes a first vertical transmission device 100 and a second vertical transmission device 200.

[0043] The first vertical transmission device 100 includes at least two first synchronous belts 110 driven by the same driving device and spaced apart by a predetermined distance, and a plurality of first carrying mechanisms 120; at least two first synchronous belts 110 are arranged in parallel and form a first spliced synchronous belt loop having a predetermined height in the vertical direction; a plurality of first carrying mechanisms 120 are circumferentially spaced apart and arranged on the first spliced synchronous belt loop.

[0044] The second vertical transmission device 200 includes at least two second synchronous belts 210 driven by the same driving device and spaced a predetermined distance apart, and a plurality of second carrying mechanisms 220; at least two second synchronous belts 210 are arranged in parallel to form a second spliced synchronous belt loop having a predetermined height in the vertical direction; a plurality of second carrying mechanisms 220 are circumferentially spaced apart and arranged on the second spliced synchronous belt loop.

[0045] The first spliced synchronous belt loop and the second spliced synchronous belt loop are spaced a predetermined distance apart, and the first carrying mechanism 120 and the second carrying mechanism 220 at the same horizontal height form a carrying unit for carrying transmission loads of various sizes.

[0046] In the above implementation process, the first vertical transmission device 100 and the second vertical transmission device 200 adopt a synchronous belt structure. The synchronous belt has a smooth surface and a toothed surface. A plurality of synchronous belts are arranged at intervals to form a spliced synchronous belt loop with a vertical gap. The toothed surface structure of the spliced synchronous belt loop enables the synchronous belt to form a continuous lifting structure, and the smooth surface of the synchronous belt can be used for the installation of the first carrying mechanism 120 / second carrying mechanism 220. The first carrying mechanism 120 / second carrying mechanism 220 extends a predetermined length in the width direction of the smooth surface of the synchronous belt. The first carrying mechanism 120 / second carrying mechanism 220 can carry transmission loads 300 of different sizes. At the same time, at least two first synchronous belts 110 in the first vertical transmission device 100 are spaced apart, and the spacing distance can meet the installation of the first carrying mechanism 120 / second carrying mechanism 220 of different lengths, and thus can also meet the mounting of transmission devices of different sizes. When the first carrying mechanism 120 / second carrying mechanism 220 carries transmission loads of different sizes, the first carrying mechanism 120 and the second carrying mechanism 220 at the same horizontal height of the first vertical transmission device 100 and the second vertical transmission device 200 spaced a predetermined distance apart can form a carrying unit capable of carrying transmission loads of various sizes, so as to be applicable to different transmission requirements.

[0047] It should be noted that the transmission load 300 described in the embodiments of the present application can be either an item directly to be transmitted, or a packaging device for containing the item to be transmitted, or a transmission load 300 structure customized specifically for delivering items, etc.

[0048] In a possible implementation manner, the first spliced synchronous belt loop and the second spliced synchronous belt loop are arranged at the same height and aligned, and are spaced a predetermined distance apart in the horizontal direction; the first spliced synchronous belt loop and the second spliced synchronous belt loop have the same speed but opposite directions of rotation.

[0049] The first spliced synchronous belt loop and the second spliced synchronous belt loop are arranged with a vertical offset, and the part where the first spliced synchronous belt loop and the second spliced synchronous belt loop are aligned vertically constitutes the vertical transmission channel of the vertical lifting device. When the first spliced synchronous belt loop and the second spliced synchronous belt loop are arranged at the same height and aligned, the first vertical transmission device 100 and the second vertical transmission device 200 can form the longest vertical transmission channel in the vertical direction by using the two spliced synchronous belt loops, making the smooth surfaces of the spliced synchronous belt loops be utilized to the greatest extent and saving the manufacturing cost. The first spliced synchronous belt loop and the second spliced synchronous belt loop have the same speed but opposite rotation directions. The first carrying mechanism 120 and the second carrying mechanism 220 at the same horizontal height can support both sides of the transmission load 300 respectively. Therefore, the transmission of the transmission load 300 during the vertical lifting process will be more stable.

[0050] Figure 2 FIG. is a schematic structural diagram of another vertical lifting device shown according to an embodiment of the present application. Refer to Figure 2 , the second spliced synchronous belt loop is located at a predetermined position inside the first spliced synchronous belt loop. The smooth surfaces of the first spliced synchronous belt loop and the second spliced synchronous belt loop are parallel, of equal width and opposite to each other, and the first spliced synchronous belt loop and the second spliced synchronous belt loop have the same speed and rotation direction.

[0051] In the above implementation process, the first spliced synchronous belt loop is located at a predetermined distance outside the second spliced synchronous belt loop, that is, the first spliced synchronous belt loop and the second spliced synchronous belt loop form two vertical transmission channels. The widths of the two vertical transmission channels in the horizontal direction can be the same or different. When the widths of the two vertical transmission channels in the horizontal direction are the same, that is, the vertical central planes of the first spliced synchronous belt loop and the second spliced synchronous belt loop coincide, the same size requirements for the transport loads on both sides are provided. When the widths of the two vertical transmission channels in the horizontal direction are different, the vertical transmission channel with a smaller width can accommodate a transmission load with a smaller size, and the vertical transmission channel with a larger width can accommodate a transmission load with a larger size. Therefore, a wider range of size requirements can be met.

[0052] The first spliced synchronous belt loop and the second spliced synchronous belt loop have the same rotation direction and rotation speed. Then, the carrying units formed by the first carrying mechanism 120 and the second carrying mechanism 220 at the same horizontal height in each vertical transmission channel can support both sides of the transmission load 300 respectively. Therefore, the transmission of the transmission load 300 during the vertical lifting process will be more stable. In this structural mode, the first spliced synchronous belt loop and the second spliced synchronous belt loop can simultaneously form two vertical transmission channels, so it has a relatively large carrying capacity.

[0053] In a possible implementation manner, Figure 2In the vertical lifting device shown, the circumferences of the first spliced synchronous belt loop and the second spliced synchronous belt loop are both integer multiples of M, where M is the length of the synchronous belt section corresponding to a predetermined number of teeth, and one or more load-carrying units are installed within the synchronous belt section; the circumference of the first spliced synchronous belt loop is KM more than the circumference of the second spliced synchronous belt loop, and K is an integer greater than or equal to 2.

[0054] In a possible implementation manner, in the structure where two vertical transmission channels are simultaneously formed by the first spliced synchronous belt loop and the second spliced synchronous belt loop, in each vertical transmission channel, the starting point and the ending point of each synchronous belt section in the first spliced synchronous belt loop are set to be at the same height and aligned with the starting point and the ending point of each synchronous belt section in the second spliced synchronous belt loop, and the intervals of the load-carrying units within the two synchronous belt sections that are aligned at the same height are regular in the vertical direction. For example, if one load-carrying unit is set in a synchronous belt section of the first spliced synchronous belt loop, then one load-carrying unit is also set in the synchronous belt section of the second spliced synchronous belt loop that is aligned with it at the same height. If three load-carrying units are set in a synchronous belt section of the first spliced synchronous belt loop, then three load-carrying units are also set in the synchronous belt section of the second spliced synchronous belt loop that is aligned with it at the same height, and the two groups of three load-carrying units are aligned at the same height. It should be noted that the first spliced synchronous belt loop can be divided into multiple synchronous belt sections of different lengths, and the number of load-carrying units in each synchronous belt section may not be the same. The division criterion of the second spliced synchronous belt loop is the same as that of the first spliced synchronous belt loop.

[0055] In an implementation scheme of the load-carrying unit, refer to Figure 1 , the first load-carrying mechanism 120 is fixed to the smooth surface of the first spliced synchronous belt loop by bolts, and the first load-carrying mechanism 120 is configured with a U-shaped or L-shaped hook; the second load-carrying mechanism 220 is fixed to the smooth surface of the second spliced synchronous belt loop by bolts, and the second load-carrying mechanism 220 is configured with a U-shaped or L-shaped hook, and the transmission load is configured with a hanging structure that cooperates with the U-shaped or L-shaped hook and can realize the hanging of the transmission load.

[0056] It should be noted that the first load-carrying mechanism 120 and the second load-carrying mechanism 220 in this application can be a single U-shaped hook structure or an L-shaped hook, or a combined structure of a long strip-shaped plate beam and a U-shaped hook. Refer to Figure 3 , one side wall of the U-shaped hook 121 is fixed to the long strip-shaped plate beam 122, and the other side wall is used to support the transmission load. In the implementation manner of this application, the long strip-shaped plate beam 122 is only exemplary. Any structure that can be fixedly connected to the smooth surface of the first spliced synchronous belt loop or the smooth surface of the second spliced synchronous belt loop, and can also fix the U-shaped hook 121 or the L-shaped hook falls within the protection scope of this application.

[0057] Figure 4Schematic structural diagram of a vertical lifting device shown according to an embodiment of the present application. Figure 5 is Figure 4 Partial structure diagram of the vertical lifting device shown. Figure 4 and Figure 5 Another implementation of the load-bearing unit is shown in, see Figure 4 and Figure 5 , the first load-bearing mechanism 120 includes a first hanging beam 123, a first hook group 124 and a second hook group 125 rigidly connected to the first hanging beam 123; the first hanging beam 123 extends along the bandwidth direction of the first spliced synchronous belt loop and is fixed on the smooth surface of the first spliced synchronous belt loop; the first hook group 124 and the second hook group 125 are separated by a predetermined distance in the bandwidth direction of the first spliced synchronous belt loop, and both extend a predetermined length in the direction perpendicular to the length of the first hanging beam 123. The first hook group 124 can be one hook or a plurality of hooks arranged in sequence in the direction perpendicular to the length of the first hanging beam 123. Correspondingly, the second hook group 125 can be one hook or a plurality of hooks arranged in sequence in the direction perpendicular to the length of the first hanging beam 123.

[0058] The second load-bearing mechanism 220 includes a second hanging beam 223, a third hook group 224 and a fourth hook group 225 rigidly connected to the second hanging beam 223; the second hanging beam 223 extends along the bandwidth direction of the second spliced synchronous belt loop and is fixed on the smooth surface of the second spliced synchronous belt loop; the third hook group 224 and the fourth hook group 225 are separated by a predetermined distance in the bandwidth direction of the second spliced synchronous belt loop, and both extend a predetermined length in the direction perpendicular to the length of the second hanging beam 223. The third hook group 224 can be one hook or a plurality of hooks arranged in sequence in the direction perpendicular to the length of the second hanging beam 223. Correspondingly, the fourth hook group 225 can be one hook or a plurality of hooks arranged in sequence in the direction perpendicular to the length of the second hanging beam 223.

[0059] The hooks in the first hook group 124 and the hooks in the second hook group 125 are arranged opposite to each other. The hooks in the third hook group 224 and the hooks in the fourth hook group 225 are arranged opposite to each other, the first hook group 124 and the third hook group 224 are aligned, the second hook group 125 and the fourth hook group 225 are aligned, and the first hook group 124, the second hook group 125, the third hook group 224 and the fourth hook group 225 jointly carry a transmission load. In the above setting, by adjusting the spacing between the first hook group 124 and the second hook group 125, and the spacing between the third hook group 224 and the fourth hook group 225, transmission loads of different sizes can be accommodated, enhancing the adaptability of the vertical lifting system.

[0060] In a possible implementation, see Figure 4, the first bearing mechanism 120 further includes a fifth hook group 126 and a sixth hook group 127; the fifth hook group 126 and the sixth hook group 127 are arranged mirror-symmetrically with respect to the horizontal center plane of the first hanging beam 123 relative to the first hook group 124 and the second hook group 125. The second bearing mechanism 220 further includes a seventh hook group 226 and an eighth hook group 227; the seventh hook group 226 and the eighth hook group 227 are arranged mirror-symmetrically with respect to the horizontal center plane of the second hanging beam 223 relative to the third hook group 224 and the fourth hook group 225.

[0061] In the above implementation, the first hook group 124 and the second hook group 125 located below the first hanging beam 123, and the third hook group 224 and the fourth hook group 225 located below the second hanging beam 223 carry a transmission load 300 in a vertical transmission channel. When the bearing unit rotates into the second vertical transmission channel along with the first spliced synchronous belt loop and the second spliced synchronous belt loop, the first hook group 124 and the second hook group 125 are located above the first hanging beam 123, the third hook group 224 and the fourth hook group 225 are located above the second hanging beam 223, the fifth hook group 126 and the sixth hook group 127 are located below the first hanging beam 123, and the seventh hook group 226 and the eighth hook group 227 are located below the second hanging beam 223, so that a bearing unit has the bearing capacity in both vertical transmission channels, greatly increasing the carrying capacity of the vertical lifting device.

[0062] Figure 6 It is a partial structural schematic diagram of a vertical lifting device shown according to an embodiment of the present application. Refer to Figure 6 and Figure 1 , a third synchronous belt 130 is further provided at the adjacent position of each first synchronous belt 110; the third synchronous belt 130 is driven by the driving device of the first synchronous belt 110. A fourth synchronous belt 230 is further provided at the adjacent position of each second synchronous belt 210; the fourth synchronous belt 230 is driven by the driving device of the second synchronous belt 210.

[0063] In the above implementation process, the third synchronous belt 130 and the first synchronous belt 110 are driven by the same driving device, that is, the third synchronous belt 130 and the first synchronous belt 110 together form the first spliced synchronous belt loop, and the first carrying mechanism 120 is fixedly connected to the first spliced synchronous belt loop. When the first synchronous belt 110 breaks or is damaged, the third synchronous belt 130 can support the first carrying mechanism 120 to continue moving. The fourth synchronous belt 230 and the second synchronous belt 210 are driven by the same driving device, that is, the fourth synchronous belt 230 and the second synchronous belt 210 together form the second spliced synchronous belt loop, and the second carrying mechanism 220 is fixedly connected to the second spliced synchronous belt loop. When the second synchronous belt 210 breaks or is damaged, the fourth synchronous belt 230 can support the second carrying mechanism 220 to continue moving. That is, the first synchronous belt 110 and the third synchronous belt 130 are anti-break safety devices for each other, and the second synchronous belt 210 and the fourth synchronous belt 230 are anti-break safety devices for each other, thereby preventing the transmission load 300 and other transmission devices from falling due to the breakage of the synchronous belt.

[0064] Figure 7 FIG. is a schematic structural diagram of a vertical lifting device provided with rollers according to an embodiment of the present application. Refer to Figure 7 , rollers 400 are provided at both ends of the first carrying mechanism 120 and both ends of the second carrying mechanism 220. Correspondingly, the vertical lifting device further includes a first track 500 and a second track 600.

[0065] The first track 500 is arranged on both sides of the first spliced synchronous belt loop; the rollers at both ends of the first carrying mechanism 120 always rollingly cooperate with the first tracks 500 on both sides when rotating with the first spliced synchronous belt loop. The second track 600 is arranged on both sides of the second spliced synchronous belt loop; the rollers at both ends of the second carrying mechanism 220 always rollingly cooperate with the second tracks 600 on both sides when rotating with the second spliced synchronous belt loop.

[0066] In the above implementation process, rollers are provided at both ends of the first carrying mechanism 120 and both ends of the second carrying mechanism 220, the first track 500 is arranged on both sides of the first spliced synchronous belt loop, and the second track 600 is arranged on both sides of the second spliced synchronous belt loop. The rollers roll in the first track 500 and the second track 600, and the first track 500 and the second track 600 define the running track of the rollers, thereby limiting the outward warping of both ends of the first carrying mechanism 120 and both ends of the second carrying mechanism 220, avoiding the risk of the transmission load 300 slipping, improving the safety of the vertical lifting device, and also enabling a larger applicable range of the load of the transmission load 300 in the vertical lifting device.
