Vertical circulating type article storage device

Abstract

A vertical circulating type article storage device comprises a plurality of columns of racks arranged in a base frame 5 side by side, after a first rack column is integrally lifted to a high position by a lifting mechanism, racks 1-2 at the non-top end of the first rack column are supported by a falling resisting mechanism, and then the rack 1-1 at the top end of the first rack column is moved to the top end of a second rack column along a guide rail through a top transverse moving mechanism; and the racks 1-3 at the bottom end of the second rack row are translated to the vacant positions at the bottom end of the first rack row by the bottom translating mechanism. And after the second rack row is released from descending resistance, the lifting mechanism integrally descends the second rack row where the racks 1-1 are located to a low position. The circulation step is carried out once or multiple times, and any rack can be lowered to the entrance of the bottom layer to pick up and send articles such as vehicles. The device is compact in structure, high in space utilization rate, beneficial to cost reduction, flexible in application, free of collapse risks, high in wind resistance and high in safety, and has the lower overall height in the non-operation period.

Description

Technical Field

[0001] This invention pertains to mechanical item storage technology, and particularly relates to multi-layer item storage technology with a vertical circulating transmission mechanism. Background Technology

[0002] Existing item storage technologies with vertical circulation mechanisms have the following drawbacks:

[0003] 1. Due to the limitations of the principle of the upper and lower rotating ends, a relatively wide space needs to be reserved between the left and right columns of storage units. The layer height of each column of storage units must be significantly greater than the unit height. The corner space outside the upper and lower rotating paths of the loop body cannot be used for item storage, which reduces the space utilization rate.

[0004] 2. A single loop can only have two columns of storage units. The number of columns of storage units arranged in a row can only be an even number, which cannot meet the requirements of 3 or 5 columns of units, thus limiting the flexibility of application and adaptability to the site.

[0005] 3. When applied to parking equipment, because the vehicle storage unit is rigidly connected to the circulation chain, it cannot detach from the garage at the entrance and cannot realize the function of picking up and dropping off vehicles from the garage to the road. It also cannot realize the function of the bottom vehicle storage unit descending to the bottom passage space to pick up and drop off vehicles. A single circulation group cannot open multiple vehicle storage units at the entrance at the same time for picking up and dropping off vehicles.

[0006] 4. When applied to parking equipment, the need for continuous circulation components necessitates the installation of a large, integrated steel frame structure. On-site installation requires heavy-duty cranes and suitable space, increasing manufacturing and on-site assembly complexity. Compared to other parking garage types with the same number of parking spaces, its overall project cost is higher.

[0007] 5. When used in parking equipment, its suspended car carrier has poor stability and is prone to swaying in windy weather, affecting safety.

[0008] 6. When applied to parking equipment, if the circulation chain breaks, it will cause a serious accident in which all parking units collapse simultaneously, and this is difficult to prevent.

[0009] 7. When applied to parking equipment, if the equipment is to be completely enclosed, an additional frame structure needs to be erected, which not only increases the footprint but also the project cost. Summary of the Invention

[0010] Referring to the accompanying drawings, to address the shortcomings of the prior art, this invention proposes a novel vertical circulating storage device for items.

[0011] Its characteristics are:

[0012] Its components include a base frame 5, and in the vertically penetrating shaft space within the base frame 5, there are at least two rows of racks arranged side by side, each row of racks including at least two racks 1 of uniform specifications arranged vertically aligned for storing items; the number of racks 1 in each row of racks is the same.

[0013] Includes a platform lifter 2; the platform lifter 2 is provided with a platform active lifter 24, and the platform 1 is provided with a platform passive lifter 14. The platform active lifter 24 of the platform lifter 2 can be connected to the platform passive lifter 14 of the platform 1 and drive the platform 1 to follow the platform active lifter 24 to rise and fall.

[0014] Each row of test benches can be moved between a low position and a high position by the test bench lifter 2;

[0015] The top shelf 1 of the higher shelf row is about one floor higher than the top shelf 1 of the lower shelf row; there is a space below the bottom of the higher shelf row that can accommodate one shelf 1.

[0016] Including multiple gantry drag devices 54 installed on the edge of the well space of the base frame 5, each gantry drag device 54 in an active state according to the control command can jointly prevent each non-bottom gantry 1 in the low-position gantry row and each non-top gantry 1 in the high-position gantry row from descending.

[0017] Includes a top-level platform translator 3 that can be moved along the guide rail, and the top platform 1 of the platform column in the high position can be translated by the top-level platform translator 3 and superimposed on the top of another platform column in the low position.

[0018] Includes a bottom platform translator 4 that can move along the track. The bottom platform 1 of the lower platform column can be translated by the bottom platform translator 4 and sent to the bottom empty space of the adjacent platform column.

[0019] The bottom platform 1 has been removed, and the platform array of the external platform 1 has been superimposed on the top platform 1, changing from a low position to a high position; the top platform 1 has been removed, and the platform array of the external platform 1 has been moved into the bottom platform 1, changing from a high position to a low position; when the platform array that has changed to a high position has each platform depressor 54 in a disabled state according to the control command, it can be lowered to a low position by the platform lifter 2.

[0020] Based on the aforementioned essential technical features, one further technical feature is:

[0021] It includes multiple platform lifters 2, and each of the platform columns performs lifting and lowering actions by means of one platform lifter 2;

[0022] The structure of the platform 1 includes platform side columns 11 connected around the platform base plate 15, and the top of the platform side columns 11 is connected to the platform top main beam 112.

[0023] The main beam 112 of the test stand is equipped with a test stand top guide rail 113; the bottom of the test stand 1 is equipped with a test stand bottom wheel 154.

[0024] When the top platform 1 of the high-positioned platform column is translated by the top platform translator 3, its platform bottom wheel 154 is supported by the rail surface of the platform top guide rail 113 of the platform 1 below it.

[0025] The top-level platform translator 3 translates along the top-level platform translator guide rail 10 set on the upper side of the base frame 5.

[0026] Based on the aforementioned essential technical features, the second further technical feature is:

[0027] It includes multiple platform lifters 2, and each of the platform columns performs lifting and lowering actions by means of one platform lifter 2;

[0028] The structure of the platform 1 includes platform side columns 11 connected around the platform base plate 15, and the top of the platform side columns 11 is connected to the platform top main beam 112; the platform top main beam 112 is provided with platform top support rollers 121; the bottom of the platform 1 is provided with platform bottom guide rails 153.

[0029] When the top platform 1 of the high-positioned platform column is translated by the top platform translator 3, the rail surface of its platform bottom guide rail 153 is supported by the platform top support wheel 121 of the platform 1 below it.

[0030] The top-level platform translator 3 translates along the top-level platform translator guide rail 10 set on the upper side of the base frame 5.

[0031] Based on the aforementioned essential technical features, the third further technical feature is...

[0032] The base frame 5 is provided with a vertical lifting guide column 513 on its side, and the platform lifting device 2 moves up and down along the lifting guide column 513.

[0033] The platform lifter 2 is provided with a top platform translator guide rail 10; the platform lifter 2 is equipped with the top platform translator 3 that translates along the top platform translator guide rail 10;

[0034] The active lifting body 24 of the platform is installed on the top platform translator 3. The top platform translator 3 can be moved laterally to change position in multiple adjacent platform columns, and the active lifting body 24 of the platform is connected to the passive lifting body 14 of the designated platform 1, so that the platform 1 can follow the active lifting body 24 to rise and fall.

[0035] Based on the aforementioned technical features, the further technical features are:

[0036] The top of the platform 1 is provided with a high-position passive lifting body 141, and the bottom of the platform 1 is provided with a low-position hanging body 143. When the top platform 1 of the platform column is lifted by the platform lifter 2, the low-position hanging body 143 of the non-bottom platform 1 in the platform column hooks the high-position passive lifting body 141 of the platform 1 below it, thereby lifting the entire platform column to a high position.

[0037] When a rack column is raised to a high position, the rack lowering bodies 13 of each rack column (excluding the top rack) are limited and supported by the rack lowering devices 54 that are in the active state. Before the rack column in the high position is about to descend, the rack lowering bodies 13 acting on the rack column are changed to an inactive state, releasing the support and lowering effect on the relevant racks. When the top rack column 1 in the high position is lowered by the rack lifter 2 by one floor height, the rack lowering bodies 13 of each rack column (excluding the bottom rack) that follow the top rack column 1 are limited and supported by the rack lowering devices 54 that are in the active state.

[0038] Based on the aforementioned technical features, the further technical features are:

[0039] The top-level platform translator 3 is located on top of the base frame 5 and translates along the top-level platform translator guide rail 10 located at the top edge of the base frame 5; the hollow space of the top-level platform translator 3, which has a frame structure, can accommodate the rising platform 1.

[0040] A lifting guide column 513 is provided on the lower side of the top platform translator 3; the platform lifting device 2 moves up and down along the lifting guide column 513; the platform lifting device 2 is provided with the platform active lifting body 24.

[0041] The passive lifting body of the platform is a low-position passive lifting body 142 of the platform 1 located on the lower side. When it is necessary to raise a designated platform column to a high position, the top platform translator 3 translates and aligns with and stops directly above a top platform 1 designated by the system. The platform active lifting body 24 of the rising platform lifter 2, with the help of the low-position passive lifting body 142 and the low-position hanging body 143, raises the platform 1 and the platform column to a high position as a whole.

[0042] Based on the aforementioned technical features, the further technical features are:

[0043] The top-level platform translator 3 is located on the upper part of the platform lifter 2 and translates along the top-level platform translator guide rail 10 located on the upper edge of the platform lifter 2; a lifter side column 21 is provided below the corner of the platform lifter 2, and a lifter guide column 513 is provided at the corner of the base frame 5.

[0044] The top-level platform translator 3 is equipped with an active lifting body 24. The platform lifter 2 moves up and down within a high and low range of a floor height by means of the lifter side column 21 along the lifter guide column 513 of the base frame 5.

[0045] When it is necessary to raise a designated row of platforms to a high position, the top platform translator 3 on the platform lifter 2 in the low position translates and aligns with and stops directly above the top platform 1 of a designated low-position platform row. The platform active lifting body 24, which rises with the platform lifter 2, raises the platform high-position passive lifting body 141, raising the entire platform row where the platform 1 is located to a high position.

[0046] When a rack is raised to a high position, and the rack lowering bodies 13 of each rack 1 (excluding the top rack) in the rack are limited and supported by the rack lowering device 54 in an active state, the connection between the low-position hanging body 143 of the top rack 1 and the high-position passive lifting body 141 of the rack 1 below it is released; then, the top rack 1 of the rack can be moved by the top rack translator 3 to be directly above the top rack 1 of another rack rack that is in a low position.

[0047] Based on the aforementioned technical features, the further technical features are:

[0048] At least one entrance side shifter 6 capable of supporting one of the platforms 1 is provided at the bottom of the base frame 5; the entrance side shifter 6 can be translated between a homing state and a side exit state; the entrance side shifter 6 in the homing state is located at the bottom of a platform row; the entrance side shifter 6 in the side exit state is located on the road surface outside the entrance of the base frame 5.

[0049] The bottom stiffener of the entrance side-moving frame 6, which performs lateral movement, passes through the pre-set gaps in the road surface slab outside the entrance;

[0050] When the platform 1 carried by the entrance side shifter 6 in the homing state is raised to a high position, the bottom platform 1 of the adjacent platform row can be moved into the entrance side shifter 6 by the bottom platform shifter 4.

[0051] When the entrance side shifter 6, which is in the homing state, carries the platform 1, the platform 1 can be moved by the bottom platform shifter 4 to the bottom empty space of the adjacent platform column at the higher position.

[0052] Compared with the various shortcomings of the prior art, the present invention has the following advantages:

[0053] 1. The required clearance between adjacent platforms in all directions is very small; when not in operation, the overall height of the device is only slightly higher than the top of the top platform. When not in operation, all platforms in the entire device are densely and neatly distributed in a matrix. Only during the short period of operation does the top of the base frame have platform components that are raised, lowered, and moved, resulting in high space utilization and good aesthetic appearance.

[0054] 2. The device can be applied in various situations using a matrix configuration with a minimum of 2 layers and 2 columns. When applied to parking equipment, the area of ​​two standard ground parking spaces can be increased to 4, 6, 8, or even more parking spaces; on an area of ​​3 ground parking spaces, the multi-column shared circulation mechanism can be used to increase to 6, 9, 12, or even more parking spaces, making each layer of the device an effective storage space, which can flexibly adapt to various small and scattered sites.

[0055] 3. Because the platform is an independent component and not rigidly fixed to the base frame and transmission mechanism, it can be temporarily moved to a space outside the base frame when needed via a transmission device. This not only meets the specific usage requirements of the goods entering and leaving the warehouse but also facilitates the maintenance and replacement of designated platforms. When applied to parking equipment, at vehicle entrances and exits, the vehicle-carrying platform can be moved to the road surface outside the warehouse using the entrance side shifter, thus facilitating vehicle entry and exit. Multiple entrances and exits can be opened on the ground floor of the same warehouse. Furthermore, a lifting device can be used to lower the platform at the bottom of the platform row to the lower passage space, facilitating the flow of vehicles entering and leaving the warehouse and reducing the footprint required for facilities outside the warehouse.

[0056] 4. Since both the platform and the base frame are independent components, the manufacturing process facilitates the production, transportation, and on-site assembly of modular small parts. This allows for the first construction of the frame and installation of the lifting transmission mechanism, followed by the individual components being installed from the ground entrance onto the platform. The translation and lifting mechanism is then used to gradually fill the designated compartments, which is beneficial for convenient on-site operations and creates favorable conditions for reducing project costs.

[0057] 5. Because the base frame of the device can be assembled using rigid longitudinal and transverse frames, the beam and column components can not only be directly used to integrate the transmission mechanism, but also easily accommodate diagonal bracing components to form a reliable rigid frame. Furthermore, each load-bearing component provides reliable support for the platform. Even without enclosed fencing, the base frame provides strong outdoor wind resistance, thus achieving higher safety performance.

[0058] 6. Because the rigid structure of the lower platform provides secondary physical protection against fall for the upper platform in the event of accidental failure of the drop arrester, and...

[0059] The bottom platform is also supported by the ground, so no matter what malfunction occurs in the whole device, there will be no serious accident of multiple platforms falling and collapsing, which has a high degree of safety.

[0060] 7. When applied to parking equipment, fully enclosed or semi-enclosed wall panels can be directly installed between the outer beams and columns of the base frame.

[0061] No additional wall panel support frame is required. This not only reduces project costs but also does not increase the footprint of the base frame.

[0119] Embodiment 1 of the present invention is as follows Figures 4 to 7 As shown.

[0120] See Figure 7 This is a parking device for storing vehicles designed according to the basic principle of the vertical circulation storage device of the present invention. The device consists of a frame-type base frame 5, two split-type platform lifters 2, a split-type top-level platform mover 3, a bottom-level platform mover 4, and four platforms 1 for carrying vehicles.

[0121] Within the vertically connected shaft space of the base frame 5, there are two adjacent rows of racks arranged side by side. Each row of racks includes two vertically aligned racks 1 for storing vehicles.

[0122] like Figure 4 As shown, the platform 1 includes a platform base plate 15 for carrying vehicles. Four platform side columns 11 are provided at the front and rear ends of the left and right side beams 151 of the platform base plate 15. The tops of the two pairs of platform side columns 11 are respectively connected to the platform top main beam 112. The top surface of the platform top main beam 112 is provided with a platform top guide rail 113. A pair of platform bottom wheels 154, spaced 20 cm apart, are provided on the left and right sides of the bottom of the two platform base plate end beams 152. The top of the platform side columns 11 is equipped with guide wheels 122 that can be guided by the base frame columns. Passive platform lowering bodies 13 and passive lifting bodies 14 are respectively provided on the two sides of the top of the platform side columns 11.

[0123] The front section of the platform lifter 2, consisting of a front section and a rear section arranged symmetrically in opposite directions on the front and rear sides of the platform column, is as follows: Figure 5As shown. Below the lifting device side columns 21 with lifting guide wheels 211, which are connected to both ends of the lifting device crossbeam 251, are two swingable hook-shaped active lifting bodies 24, which are synchronously driven by the lifting body drive shaft 243. The front and rear parts are raised and lowered synchronously by the top lifting mechanism through the lifting rope chain 23.

[0124] See Figure 6 The base frame 5 consists of four corner columns 511 at the left and right corners and two central columns 512 at the top. Between the front and rear top crossbeams 53, there are left and right side beams 521 and a central beam 522. Between the corner columns 511 and the central columns 512, a lower crossbeam 532 and a lower side beam 523 connect. Two independently operating platform lifters 2-1 and 2-2 move up and down along lifter guide slots 513 located on the sides of the corner columns 511 and central columns 512, respectively.

[0125] The base frame 5 has two bottom-level translation rails 55 and two base frame bottom guide wheels 56 on the ground. The two synchronously operating bottom-level platform translation devices 4 with drive bodies 41 move laterally along the front and rear bottom-level translation rails 55 respectively.

[0126] Two top-level platform translators 3 with swivelable clamp-type drive bodies 35 move synchronously along the top-level translator guide rails 10 set on the top crossbeams 53 of the front and rear base frames. Swingable hook-shaped platform decelerators 54 are provided below the front and rear ends of the left and right base frame top side beams 521 and the base frame top middle beam 522.

[0127] See Figure 7 The base frame 5 contains two rows of test benches, each row consisting of upper and lower benches 1. When the test bench rows are in the lower position, the passive lifting bodies 13 of the upper benches 1-2 and 1-3 are hooked by the swingable hook-shaped bench lifting devices 54 of the base frame 5. The bench bottom wheels 154 of the lower benches 1-1 and 1-4 are supported by the bottom bench translation guide rail 57. When the left bench row needs to be raised to the higher position, the active lifting body 24 of the left bench lifter 2-1 hooks the passive lifting body 14 of the lower bench 1-1, causing the bench 1-1 to rise. The gradually rising top guide rail 113 of the lower bench 1-1 supports the bench bottom wheel 154 of the other bench 1-2 above it, causing the passive lifting body 13 of the bench 1-2 to disengage from the bench lifting device 54. When the bottom platform 1-1 is raised by one floor, its passive anti-fall body 13 is hooked by the platform anti-fall device 54 to prevent it from falling.

[0128] See Figure 8 , continuing Figure 7During operation, the two side columns 11 of the high-level platform 1-2, supported by the platform top guide rail 113 of the platform 1-1 which has been raised to the top level, can be clamped by the clamp-type drive body 35 of the top-level platform translator 3 and moved by the top-level platform translator 3 to directly above the right platform column. During this period, the bottom platform 1-4 of the right platform column can be moved to the left by the bottom-level platform translator 4 to the empty space below the left platform column.

[0129] See Figure 9 , continuing Figure 8 During operation, after the shifted platform 1-2 is completely moved onto the platform top guide rail 113 of the top platform 1-3 of the right platform column, the active lifting body 24 of the right platform lifter 2-2 supports the passive lifting body 14 of the original top platform 1-3 of the right platform column. Then, the platform lowering device 54 immediately releases the restriction on the lowering of this platform 1-3, allowing the platform lifter 2-2 to lower the right platform column to a low position, and allowing the platform lowering device 54 to support the new top platform 1-2 and prevent it from descending.

[0130] like Figure 9 As shown, if the system requires, when the right platform column descends, the left platform column can also be simultaneously lifted to a high position by the left platform lifter 2-1 to continue the next cycle.

[0131] The operation process of this embodiment is described in [reference]. Figure 1 . Figure 1 The eight sub-diagrams shown schematically illustrate the process of exchanging positions between the two top platforms A and B and the two bottom platforms C and D. If this diagram illustrates a four-car parking system, assuming a single-step lateral movement takes 10 seconds and a single-step lifting takes 20 seconds, lowering platform A to the lower level would take no more than 50 seconds.

[0132] Example 2 Figure 10 , Figure 11 As shown.

[0133] Based on Example 1, add one column to the left and one layer upwards to create a parking device with 9 spaces. The transmission mechanism needs to be configured according to... Figure 11 As shown, the platform lifter 2 is modified to have two sets of active lifting bodies 24, one upper and one lower, making it a composite mechanism that can simultaneously lift the upper and lower platforms 1. Furthermore, an additional lower side beam 523 and a lower middle beam 524 of the base frame are required, along with platform drop devices 54 installed at their ends. Since each platform row includes three platforms, to improve the efficiency of the electromechanical system, this embodiment provides a counterweight 8 for each set of platform lifters 2.

[0134] The operation process of this embodiment is described in [reference]. Figure 2 , Figure 2The eight sub-diagrams shown schematically illustrate the process of the two top platforms A and C descending to the two ends of the bottom layer. Clearly, any one or two platforms 1 in the three platform columns can be continuously descended to any one or two positions on the bottom layer using alternating cyclic operations, simultaneously opening the entrance to pick up and drop off vehicles.

[0135] Example 3 Figure 12 , Figure 13 As shown.

[0136] This is a parking device designed according to the principles of this invention.

[0137] See Figure 12 Unlike Embodiment 1, in this embodiment, each main beam 112 of the platform 1 is equipped with five evenly distributed platform top support rollers 121, and platform bottom guide rails 153 with their rail surfaces facing downwards are installed at the front and rear ends of the platform bottom plate 15. Multiple parallel platform bottom stiffening plates 155 are arranged at equal intervals between the platform bottom guide rails 153. The top two sides of the platform side columns 11 are respectively provided with a platform passive slumping body 13 and a notch-shaped passive lifting body 14. A sunshade 115 is installed on the top of the platform 1. Top-level platform translation linkage bodies 156 are installed at the middle of both ends of the platform bottom plate 15.

[0138] See Figure 13 This embodiment installs as follows Figure 11 The platform lifter 2 shown is lifted using a lifting rod 7. The platform bottom guide rail 153 of the platform 1-1, which is raised to the top of the base frame, is supported by the platform top support rollers 121 of the two platforms 1 below it, and is connected and moved by the drive body 35 of the top platform translator and the top platform translation linkage body 156. The right side of the bottom layer of the base frame 5 is set as a vehicle access port. The bottom of the base frame 5 is provided with three rows of base frame bottom guide rollers 56 extending from the bottom of the base frame 5 to the right to the road surface outside the vehicle access port. These rollers are used to support and guide the platform bottom guide rail 153 and platform bottom stiffening plate 155 of the bottom platform 1-2, which is driven by the bottom platform translator 4. The platform 1-2 can be moved out of the bottom of the base frame and enter the road surface outside the vehicle access port to pick up and drop off vehicles.

[0139] Example 4 Figure 14 As shown.

[0140] Expanding upon Example 3 by adding a row of racks creates a three-row, three-layer side-exit vertical circulation storage device as shown in the figure. The top rack 1-2, raised to a higher position, can be moved to the top of a designated rack row using the top rack translator 3 to complete the circulation operation. The rightmost rack 1-1 at the bottom of the base frame 5 can be moved into the road surface in front of the vehicle entrance / exit to pick up and drop off vehicles 9. When the bottom rack 1-2 at the bottom of the base frame 5 of the leftmost rack row needs to be moved out of the vehicle entrance / exit, the middle rack row and the right rack row can be raised to a higher position first to make way for the bottom passage.

[0141] Example 5 Figure 15 , Figure 16 As shown.

[0142] This embodiment is a 9-car parking device with three rows of parking platforms designed according to the principles of the present invention. Unlike the previous embodiments, the circulation direction in this embodiment is the same as the length direction of the vehicle 9. The platform top guide rail 113 is located on the top left and right sides of the platform 1. Two pairs of platform bottom wheels 154 are respectively installed at both ends of the outer side beams 151 of the platform base plate.

[0143] See Figure 16 The split-type platform lifters 2 are located in the lifter guide slots 513 on the left and right sides of the base frame 5. The platform base wheels 154 of the top platform 1-1, which is raised to the highest position, can move horizontally along the platform top guide rails 113 of the three platforms 1 below it. Each pair of platform base wheels 154, arranged at 30 cm intervals, helps to smoothly pass through the structural separation zone between the platform top guide rails 113 below. The platform 1 located at the bottom can receive and store vehicles from the rear vehicle entrance at the bottom of the base frame 5. Through cyclic transport operations, any vehicle 9 can be transported to the front exit of the base frame 5 and drive straight out.

[0144] Example 6 Figure 17 , Figure 18 As shown.

[0145] Based on Embodiment 5, the vehicle entrance / exit in this embodiment is located in the middle of the right side of the bottom layer of the base frame 5. The bottom platform 1 can be moved horizontally to a position within the vehicle entrance, such as... Figure 18 The vehicle is moved from the entrance side-shifting frame 6 to the road surface outside the vehicle entrance. The bottom reinforcement beam 63 of the side-shifting frame between the side-shifting frame side beams 62 of the entrance side-shifting frame 6 can pass through the floor gap 58 outside the base frame exit along the track. The two sections of bottom platform translation guide rail 57 on the side-shifting frame side beam 62 of the entrance side-shifting frame 6 after entering the warehouse are connected to the fixed bottom platform translation guide rail 57 at the front and rear to allow the platform 1 to enter and exit the entrance side-shifting frame 6. Because the bottom translation guide rail 55 is divided in the middle by the side-shifting track of the entrance side-shifting frame 6, independent bottom platform translation devices 4 are respectively set on the front and rear sections of the bottom translation guide rail 55, and the platform 1 is driven to translate into and out of the entrance side-shifting frame 6 through the bottom platform translation linkage 157 in the middle of the front and rear ends of the platform base plate 15.

[0146] Example 7 Figures 19 to 24 As shown.

[0147] This is a double-layer, double-row parking device designed according to the present invention.

[0148] The structure of platform 1 is as follows Figure 19As shown, its passive lifting body 14 is divided into a high position and a low position. The high position passive lifting body 141 is located on the outer sides of both ends of the main beam 112 at the top of the platform, and the low position passive lifting body 141 is located on the outer side of the lower part of the side column 11 of the platform. The passive slumping body 13 of the platform is located at the front and rear ends of the side beam 151 of the bottom plate of the platform.

[0149] See Figures 20 to 22 The platform lifter 2 extends laterally to the front and rear ends of the left and right platform columns. The top platform translator 3 is installed inside the platform lifter 2 and moves along the top platform translator guide rail 10 set inside the platform lifter 2 to the front and rear ends of the left and right platform columns, and rises and falls with the platform lifter 2. The active lifting body 24 is set on both sides of the top platform translator 3 and is divided into a high-position active lifting body 241 and a low-position active lifting body 242. The lifting channel of the platform lifter 2 is set inside the middle column 512 of the base frame. A telescopic platform lowering device 54 is set inside the bottom end of the middle column 512 of the base frame, and the remaining platform lowering devices 54 are set inside both ends of the lower beam 523 of the base frame.

[0150] See Figure 23 When the top-level platform translator 3 lifts the left platform column, the high-level active lifting body 241 supports the low-level passive lifting body 142 of the upper platform, and the low-level active lifting body 242 supports the high-level passive lifting body 141 of the lower platform.

[0151] See Figure 24 When the left platform column is raised to its highest position, the lower platform 1-2 of the left platform column is supported by the extended platform lowering device 54. The upper platform 1-1, supported by the high-position active lifting body 241, moves to the top of the right platform column following the right-moving top platform shifter 3. Simultaneously, the bottom platform 1-3 of the right platform column is moved to the empty space on the left by the bottom platform shifter 4, thus completing one cycle of the equipment.

[0152] Example 8 Figures 25 to 28 As shown.

[0153] This is a double-layer, double-row parking device designed according to the present invention.

[0154] The structure of its platform 1 is shown in the figure. Figure 25 The platform base plate side beam 151 has perforated passive descent bodies 13 on its front and rear outer sides, and a low-position hanging body 143 at its end. The concave bottom end of the platform side column 11 has a low-position passive lifting body 142, the outer side of its top has a platform top hanging wheel 123, and the inner side has a high-position passive lifting body 141. In the same platform row, the low-position hanging body 143 of the upper platform 1-1 hooks the high-position passive lifting body 141 of the lower platform 1-2. Above the middle of the main beam 112 of the platform top is a bottom platform translation linkage body 157.

[0155] See Figure 26 The upper part of the top-level platform translator 3 is a hollow top frame structure formed by the top-level platform translator side beams 37 and the top-level platform translator crossbeams 34. The top-level platform translator's traveling wheels 36 are installed at the four corners of the top frame. The top-level platform translator's side columns 33 are located near the lower part of the four corners of the top frame. The inner side of the top-level platform translator's side columns 33 is provided with a lifting guide groove 513. The split-type platform translator 2 is installed between the front and rear pairs of top-level platform translator side columns 33. The left and right ends of the lifting crossbeam 251 of the platform translator 2 are provided with active lifting bodies 24.

[0156] See Figure 27 The top-level platform translator 3 moves left and right along the top-level translator guide rail 10 on the front and rear base frame top crossbeams 53 of the base frame 5. Telescopic platform sag devices 54 are installed at the front and rear ends of the lower side beam 523 and the lower middle beam of the base frame. The split-type bottom-level platform translator 4 moves along the bottom-level translator guide rail 55 located inside the lower crossbeam 532 of the base frame. The edge of the bottom-level platform translation guide rail 57 serves as the bottom-level platform translation guide rail 57.

[0157] See Figure 28 The platform top hanger 123 of platform 1-3 at the bottom of the right platform column is supported by the bottom platform translation guide rail 57. When the left platform column needs to be raised to a higher position, the top platform translation device 3 translates to the left and aligns with the upper platform 1-1 of the left platform column, allowing the active lifting body 24 of the platform lifter 2 to hook the low-position passive lifting body 142 of platform 1-1 and lift it upward. At the same time, the high-position passive lifting body 141 of the lower platform 1-2 is hooked by the low-position hanging body 143 of the upper platform 1-1 and lifted. The upper platform 1-1, raised to a higher position, is translated to the right by the top platform translation device 3. The bottom platform translation linkage body 157 of platform 1-3 at the bottom of the right platform column is clamped by the drive body 41 of the bottom platform translation device and translated.

[0158] Compared to ground-based tracks, the elevated bottom-level platform translation rail 57 is easier to manufacture and install, as it does not rely on a ground foundation.

[0159] Example 9 Figure 29 As shown.

[0160] Based on Example 8, this example adds layers to form a parking device with three layers and three columns of nine parking platforms. For this purpose, an additional layer of beam components and corresponding platform deceleration devices 54 are required, along with a set of bottom-layer platform translators 4.

[0161] Example 10 Figures 30 to 34 As shown.

[0162] The structure of its platform 1 is shown in the figure. Figure 30The front and rear platform bottom plate end beams 152 are equipped with low-position hanging bodies 143 on both sides. The bottom surfaces of both ends of the platform top main beam 112 serve as passive descent bodies 13. The inner sides of both ends of the platform top main beam 112 are equipped with passive lifting bodies 14, the outer sides of both ends are equipped with platform top hanging wheels 123, and the middle upper part is equipped with a bottom platform translation linkage body 157.

[0163] For the construction of the top-level platform translation device 3, please refer to [link / reference]. Figure 31 The left and right ends of the front and rear top-level platform translator crossbeams 34, which are connected by the side beams 37 of the top-level platform translator, are provided with traveling wheels 36 that are synchronously driven by the main shaft 38 of the top-level platform translator, and the outer side is provided with an active lifting body 24.

[0164] See Figure 32 The lifting beam 251 and the lifting longitudinal beam 252 together form the top frame structure of the platform lifting device 2, with a lifting device side column 21 located below the dead angle. The traveling wheels 36 of the top platform translator move along the top platform translator guide rail 10 above the lifting beam 251. The lifting power of the platform lifting device 2 comes from a lifting system consisting of two sets of synchronously driven lifting rope chains 23 on the left and right sides. Figure 33 As shown, the fixed end of the rope chain 23 is fixed below the end of the top side beam 521 of the base frame. The lifting device side column 21 slides vertically in the inner guide groove of the corner column 511 of the base frame.

[0165] See Figure 34 The active lifting body 24 of the top-level platform translator 3, which rises with the platform lifter 2, lifts the passive lifting body 14 of the platform 1-1 at the top of the left platform column, raising the platform 1-1. The passive lifting body 14 of the lower platform 1-2 is hooked by the low-position hanging body 143 of the upper platform 1-1 and raised to a high position. Then, the bottom of its platform top main beam 112 is supported by the extended platform lowering device 54. Subsequently, the top-level platform translator 3 moves the platform 1-1 to the upper part of the right platform column. The platform top hanging wheel 123 of the bottom platform 1-3 of the right platform column is supported by the suspended bottom platform translation guide rail 57. Its bottom platform translation linkage body 157 is clamped and pushed to the left empty position by the drive body 41 of the bottom platform translator, which translates along the suspended bottom platform translation guide rail 55.

[0166] Example 11 Figure 35 As shown.

[0167] Based on Example 10, this example adds layers to form a parking device with three layers, three columns, and nine parking platforms. To achieve this, an additional layer of beam components and corresponding platform decelerators 54 are required, along with a set of bottom-layer platform translators 4 to allow simultaneous movement of two platforms 1.

[0168] The top of the platform lift 2 in Examples 10 and 11 is suitable for being fitted with a complete canopy that can provide shade and rain protection.

[0169] The vehicle entrances and exits in the above embodiments clearly have the space and conditions to install safety roller shutters. Guardrails conforming to specifications can also be installed between the columns at the bottom of the base frame 5. The solutions shown in each embodiment can all be arranged in a parallel, interconnected manner, depending on the site conditions.

[0170] If required by the application environment, it can also be like Figure 36 As shown, an elevated ground-level passageway is constructed, equipped with a simple lifting platform 57 with a ground-level platform sliding guide rail 57. This platform 1 is lowered to the ground level of the ground-level passageway to directly receive and transport vehicles. The remaining space in the ground-level passageway is used to arrange driveways for entering and exiting the warehouse and pedestrian walkways. This layout clearly helps save equipment footprint and improves space utilization.
