DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] It should be noted that the multi-layer lifting device of the present application is mainly used to deal with the blockage of the conveyor belt in the centralized storage section of the cigarette transport channel. Before centralized storage, the cigarette cartons are delivered to the conveyor belt by separate machines in different places. Therefore, in the transportation area where the cigarette cartons are centralized for storage, the multi-layer lifting device of the present application can be used to deal with the blockage problem. When not in use, the multi-layer lifting device of the present application can be lowered, folded and placed on both sides of the aisle. When needed, it can be pushed to the blocked position through the aisle.

[0026] See also Figure 1-4 In order to solve the above problems, the utility model proposes a multi-layer lifting device, including a maintenance platform 1, multiple lifting components 2 and a moving component 3. The multiple lifting components 2 are stacked in a vertical direction, one of the lifting components 2 carries the maintenance platform 1, and the maintenance platform 1 is slidably connected to the lifting component 2 through the moving component 3, so that the maintenance platform 1 is hung between the equipment to be repaired and the lifting component 2.

[0027] In order to enable the multi-layer lifting assembly 2 of the present application to be freely moved to the blocked position for more flexible use and placement, the multi-layer lifting assembly 2 also includes a base plate 7 and sliding wheels 4. A plurality of sliding wheels 4 are arranged at the bottom of the base plate 7, and the base plate 7 always remains in a horizontal state. A plurality of groups of lifting assemblies 2 are arranged on the base plate 7 in a vertical direction, and each lifting assembly 2 is connected end to end. Specifically, the tail end of the lifting assembly 2 located at the bottom is connected to the base plate 7, and the top end of the lifting assembly 2 located at the bottom is connected to the tail end of another lifting assembly 2, and so on. A multi-layer lifting assembly 2 can be set, and the lifting assembly 2 located at the top is equipped with a maintenance platform 1, and the maintenance platform 1 is slidably connected to the lifting assembly 2 through the moving assembly 3, so that the maintenance platform 1 can slide horizontally along the direction of the moving assembly 3, so that the maintenance platform 1 can be hung between the equipment to be repaired and the lifting assembly 2, and the worker lying on the maintenance platform 1 can directly clear the blockage in the passage for transporting cigarettes.

[0028] It can be understood that the multi-layer lifting device of the present application can be provided with a corresponding number of lifting components 2 according to actual needs.

[0029] Exemplarily, a sliding wheel 4 can be provided at each of the four ends of the base plate 7 so that the base plate 7 always maintains a horizontal state, and two sets of lifting components 2 can be provided on the base plate 7, the tail end of the lifting component 2 located at the bottom is connected to the base plate 7, the top end of the lifting component 2 located at the bottom is connected to the tail end of the lifting component 2 located at the top, and the top end of the lifting component 2 located at the top is equipped with a maintenance platform 1, and the maintenance platform 1 is slidably connected to the lifting component 2 located at the top through the moving component 3. The maintenance platform 1 can be a wider long board, and guardrails can be provided around the maintenance platform 1 to improve safety. The maintenance platform 1 can be placed with some commonly used dredging tools, and in actual use, workers need to lie on the maintenance platform 1, so the size of the maintenance platform 1 can be designed to be suitable in combination with the overall structure of the multi-layer lifting device of the present application and the volume of an adult.

[0030] In order to enable the multi-storey lifting device of the present application to be placed still in the aisle when not in use, a locking member 41 is further provided on the sliding wheel 4 to lock the self-rotation of the sliding wheel 4 .

[0031] It is understandable that the locking member 41 can be a brake, a latch, etc., which can lock the rotation of the sliding wheel 4.

[0032] See also Figure 1-3 The lifting assembly 2 specifically includes a lifting platform 21, a driving member 22 and a telescopic part 23. The lifting platform 21 is mounted on the telescopic part 23. The driving member 22 is connected to the telescopic part 23 by transmission, so that the telescopic part 23 drives the lifting platform 21 to rise and fall. When multiple sets of lifting assemblies 2 are provided, the telescopic part 23 of another set of lifting assemblies 2 is provided on the lifting platform 21 of one set of lifting assemblies 2. The telescopic part 23 includes a first plate 231 and a second plate 232. The center of the first plate 231 overlaps with the center of the second plate 232 and is rotatably connected at the overlap. The upper end of the first plate 231 and the lower end of the second plate 232 are respectively slidably connected to the structure in contact with the two. The lower end of the first plate 231 and the upper end of the second plate 232 are respectively rotatably connected to the structure in contact with the two. The driving member 22 is connected to one of the sliding ends of the telescopic part 23 by transmission, so that the telescopic part 23 drives the lifting platform 21 to rise. The upper end of the first plate 231 and the lower end of the second plate 232 are sliding ends.

[0033] Exemplarily, two groups of lifting assemblies 2 can be stacked on the bottom plate 7, the telescopic part 23 of the first group of lifting assemblies 2 is arranged on the lifting platform 21 of the second group of lifting assemblies 2, and the telescopic part 23 of the second group of lifting assemblies 2 is arranged on the bottom plate 7. Specifically, the upper end of the first plate 231 of the first group of lifting assemblies 2 can be slidably connected to the lifting platform 21 of the first group of lifting assemblies 2 through the slide rail 233; the lower end of the second plate 232 of the first group of lifting assemblies 2 can be slidably connected to the lifting platform 21 of the second group of lifting assemblies 2 through the slide rail 233. The lower end of the first plate 231 of the first group of lifting assemblies 2 is rotatably connected to the lifting platform 21 of the second group of lifting assemblies 2; the upper end of the second plate 232 of the first group of lifting assemblies 2 is rotatably connected to the lifting platform 21 of the first group of lifting assemblies 2. The upper end of the first plate 231 of the second group of lifting assemblies 2 is slidably connected to the lifting platform 21 of the second group of lifting assemblies 2 through the slide rail 233; the lower end of the second plate 232 of the second group of lifting assemblies 2 is slidably connected to the bottom plate 7 through the slide rail 233. Each first plate 231 and each second plate 232 is rotatably connected to each slide rail 233 through a slider. Each slide rail 233 is arranged in the horizontal direction, and each slider runs along the direction of the corresponding slide rail 233. The length of the slide rail 233 can be adaptively adjusted according to the actual application situation to ensure that the lifting platform 21 of each lifting assembly 2 can reach the required height. The driving member 22 of each lifting assembly 2 is arranged at the outer end of the slide rail 233, and the output end of the driving member 22 is transmission-connected with the slider at the lower end of the second plate 232. The fixed end of the driving member 22 of the first lifting assembly 2 is fixedly connected to the lifting platform 21 of the second lifting assembly 2; the fixed end of the driving member 22 of the second lifting assembly 2 is fixedly connected to the bottom plate 7. When the driving member 22 drives the lower end of the second plate 232 to slide toward the lower end of the first plate 231, the upper end of the second plate 232 rotates upward. Since the overlap of the first plate 231 and the second plate 232 is a rotation connection, the upper end of the first plate 231 rotates upward synchronously and slides toward the upper end of the second plate 232 along the direction of the slide rail 233. At the same time, the lower end of the first plate 231 and the upper end of the second plate 232 rotate accordingly, so that the telescopic part 23 is compressed from the horizontal direction; otherwise, the telescopic part 23 is stretched from the horizontal direction. When the telescopic part 23 is compressed from the horizontal direction, the telescopic part 23 lifts the lifting platform 21 and the maintenance platform 1 mounted on the lifting platform 21; when the telescopic part 23 is stretched from the horizontal direction, the telescopic part 23 puts down the lifting platform 21 and the maintenance platform 1 mounted on the lifting platform 21.

[0034] The specific superposition method of the two sets of lifting components 2 includes:

[0035] As a feasible implementation, the lifting platforms 21 of the two lifting components 2 are arranged in parallel with non-overlapping centers, and the telescopic parts 23 corresponding to the two lifting components 2 are not arranged on the same straight line, which may cause the structure of the multi-layer lifting device to be unstable.

[0036] As a preferred embodiment, the lifting platforms 21 of the two lifting assemblies 2 are arranged in parallel and overlapped at the centers, and the telescopic parts 23 corresponding to the two lifting assemblies 2 are arranged on the same straight line, so that the structure of the multi-layer lifting device is more stable.

[0037] See also Figure 1 and Figure 3 In order to improve the stability of the lifting platform 21 and the maintenance platform 1 mounted on the lifting platform 21 during lifting, the lifting component 2 is coaxially provided with multiple sets of telescopic parts 23.

[0038] For example, two sets of telescopic parts 23 can be coaxially arranged at both ends of the lifting platform 21, and the driving parts 22 of the two sets of lifting components 2 synchronously drive the corresponding telescopic parts 23 to extend and retract, so that the lifting platform 21 can be lifted and lowered more stably. The heights of the two sets of telescopic parts 23 are always consistent, and they extend and retract synchronously, so that the lifting platform 21 always maintains a horizontal state. When multiple sets of lifting components 2 are arranged, the axes of the telescopic parts 23 on the same side are arranged on the same straight line.

[0039] In actual use, only a single-layer maintenance platform 1 is provided, and it is impossible to clear the multi-layer cigarette transport channel at the same time.

[0040] See also Figure 1-3 In order to solve the above-mentioned problems arising in the actual application process, in a specific embodiment of the present application, each lifting component 2 is equipped with a maintenance platform 1, and the bottom plate 7 is also equipped with a maintenance platform 1, and each maintenance platform 1 is slidably connected to the structure that fits each maintenance platform 1 through a moving component 3, and each maintenance platform 1 will not interfere with the extension and retraction of the telescopic part 23.

[0041] Exemplarily, two groups of lifting assemblies 2 may be stacked, the upper end of the bottom plate 7 is connected to the tail end of the telescopic portion 23 of the first group of lifting assemblies 2, and the second group of lifting assemblies 2 is carried on the lifting platform 21 of the first group of lifting assemblies 2. Specifically, the tail end of the telescopic portion 23 of the second group of lifting assemblies 2 is connected to the lifting platform 21 of the first group of lifting assemblies 2. A maintenance platform 1 may be provided on both the bottom plate 7 and the two lifting platforms 21, and each maintenance platform 1 does not interfere with the operation of the lifting assemblies 2. A maintenance platform 1 slightly smaller in size than the lifting platform 21 may be provided on the lifting platform 21 of the first group of lifting assemblies 2, a maintenance platform 1 with a width smaller than the width of the telescopic portion 23 may be provided on the lifting platform 21 of the second group of lifting assemblies 2, and the lifting platform 21 of the second group of lifting assemblies 2 does not interfere with the extension and retraction of the telescopic portion 23, and a maintenance platform 1 having the same size as the maintenance platform 1 provided on the second group of lifting assemblies 2 may be provided on the bottom plate 7.

[0042] It is understandable that the size of the maintenance platform 1 can be adaptively adjusted according to actual application conditions, so that the maintenance platform 1 does not interfere with the lifting and lowering of the telescopic parts 23.

[0043] It should be noted that, except for the topmost maintenance platform 1 , the width of the remaining maintenance platforms 1 is smaller than the distance between the slide rail 233 and the fixed end on the same side, in order to avoid interference with the structure of the telescopic portion 23 .

[0044] It is understandable that the driving member 22 can be a driving motor, a cylinder, etc., which can achieve pushing and pulling back the sliding end.

[0045] See also Figure 1 and Figure 3 In order to improve the stability of the lifting platform 21 and the maintenance platform 1 mounted on the lifting platform 21 during lifting, the lifting component 2 is coaxially provided with multiple sets of telescopic parts 23.

[0046] Exemplarily, two sets of telescopic parts 23 may be coaxially arranged at two ends of the lifting platform 21 , and the telescopic parts 23 may be synchronously driven to be telescoped, so that the lifting platform 21 can be stably lifted and lowered.

[0047] In actual use, the maintenance platform 1 set on the bottom plate 7 can only slide horizontally and cannot be raised or lowered. When the passage at the bottom layer and other high-level passages need to be repaired at the same time, it is impossible to cooperate with multiple workers to clear all the tracks at the same time.

[0048] See also Figure 1-3 In order to solve the above problems in actual use, a power member 5 is provided between each sliding wheel 4 and the bottom plate 7, and each power member 5 synchronously drives the bottom plate 7 to rise and fall, thereby raising and lowering the maintenance platform 1 mounted on the bottom plate 7. The lifting range of the power member 5 can be adaptively adjusted according to the actual use situation.

[0049] It is understandable that the power member 5 can be a driving motor, a cylinder, etc., as long as it can achieve synchronous lifting and lowering of the base plate 7.

[0050] See also Figure 1-3 The moving assembly 3 includes a moving part 31 and a moving rail 32. Multiple moving parts 31 are arranged at the bottom of the maintenance platform 1. Corresponding to the position of each moving part 31, multiple parallel moving rails 32 pointing to the outside of the lifting platform 21 are arranged, so that the maintenance platform 1 slides along the direction of the moving rails 32.

[0051] As an implementable embodiment, the movable member 31 can be in a snap-fit ​​shape, and the movable rail 32 can be a raised rail adapted to the movable member 31. The movable member 31 and the movable rail 32 are slidably connected. Four movable members 31 can be arranged at the four ends of the bottom of the maintenance platform 1, and the maintenance platform 1 always maintains a horizontal state. Each movable member 31 is arranged in the middle, and two parallel movable rails 32 are arranged corresponding to the position of each movable member 31, and the movable rails 32 are arranged perpendicular to the telescopic part 23. The coverage area of ​​the movable rail 32 does not interfere with the setting area of ​​the telescopic part 23, so that the maintenance platform 1 can be pushed out from the bottom of the telescopic part 23, and the pushed-out end of the maintenance platform 1 can be hung on the channel to be cleared.

[0052] As a preferred embodiment, the movable member 31 can be wheel-shaped, and the movable rail 32 can be a groove adapted to the movable member 31. Four movable members 31 can be arranged at the four ends of the bottom of the maintenance platform 1, and the maintenance platform 1 always maintains a horizontal state. Each movable member 31 is arranged in the middle, and two parallel movable rails 32 are arranged corresponding to the position of each movable member 31, and the movable rails 32 are arranged perpendicular to the telescopic part 23. The coverage area of ​​the movable rails 32 and the setting area of ​​the telescopic part 23 do not interfere with each other, so that the maintenance platform 1 can be pushed out from the bottom of the telescopic part 23, and the pushed-out end of the maintenance platform 1 can be hung on the channel to be cleared.

[0053] It should be noted that the movable member 31 of the movable assembly 3 is arranged at the bottom of the maintenance platform 1, which will increase the height of the maintenance platform 1. Therefore, it is necessary to ensure that the maintenance platform 1 provided with the movable member 31 will still not affect the telescopic movement of each telescopic part 23. Specifically, when the telescopic part 23 is at the lowest point, the lowest point here can adjust the length of the slide rail 233 according to the folding degree of the telescopic part 23 actually required. When the lower end of the second plate 232 runs to the outer end of the slide rail 233, the telescopic part 23 is at the lowest point. At this time, the maintenance platform 1 provided with the movable member 31 does not contact each telescopic part 23. Therefore, the height of the movable member 31 can be adaptively adjusted according to the actual situation. At the same time, the telescopic range of the telescopic part 23 can also be adjusted by changing the length of the slide rail 233, so as to adapt to the height of the movable member 31 and the maintenance platform 1, and ensure that the telescopic part 23 will not collide with the maintenance platform 1 when it is at the lowest point.

[0054] In actual use, after the end of the maintenance platform 1 is hung on the passage to be repaired, since the movable member 31 is in a slidable state, the maintenance platform 1 may slide during the unblocking process, resulting in position displacement, and the failure to fix the position of the maintenance platform 1 may also pose a safety hazard.

[0055] See also Figure 1-4 Specific solutions include:

[0056] As a first possible implementation, a stopper 33 for locking the moving member 31 is provided on the moving member 31. When the moving member 31 is in a buckle shape, a latch, a knob, etc. can be provided as the stopper 33 to abut the moving member 31 against the moving rail 32, thereby limiting the sliding of the moving member 31; when the moving member 31 is in a wheel shape, a brake, a latch, etc. can be provided as the stopper 33 to lock the self-rotation of the moving member 31. However, locking the moving member 31 only by increasing the sliding friction or limiting the self-rotation may still cause the moving member 31 to translate in the moving rail 32.

[0057] As a second possible implementation method, a plurality of baffles that are evenly spaced and perpendicular to the movable rail 32 are arranged at the bottom of the maintenance platform 1. The setting area of ​​the baffles does not interfere with the setting area of ​​the movable part 31. The height of the baffles is smaller than the spacing between the maintenance platform 1 and the structure it is fitted with. The spacing between adjacent baffles is adapted to the width of the channel to be cleared, and can be adaptively adjusted according to actual conditions so that the baffles can be blocked by the side panels of the channel to be cleared, thereby buckling the maintenance platform 1 between the channel to be repaired and the lifting assembly 2.

[0058] As a third possible implementation method, a plurality of limit plates 61 parallel to the movable rails 32 are arranged at the bottom of the maintenance platform 1, and the setting areas of the limit plates 61 do not interfere with the setting areas of the movable parts 31. A plurality of evenly spaced limit grooves 62 are arranged on the limit plates 61, and the width of the limit grooves 62 is adapted to the thickness of the side plates of the channel to be cleared, and the spacing between the limit grooves 62 is adapted to the width of the channel to be cleared, so that the maintenance platform 1 is fixed between the channel to be repaired and the lifting assembly 2 through the limit grooves 62.

[0059] As a preferred embodiment, the first embodiment is used in combination with the second embodiment or the third embodiment to perform double locking on the maintenance platform 1 to improve safety.

[0060] See also Figure 5 When the multi-layer lifting device of the present application is used, a corresponding number of multi-layer lifting devices can be set according to the number of channels in use. The specific dredging steps include:

[0061] First, determine the blockage position and height of the passage 8 to be cleared, push the multi-layer lifting device 9 of the present application placed in the aisle 10 to the side of the blockage, and determine the height of the maintenance platform 1 using the multi-layer lifting device 9 of the present application according to the height of the blockage. For example, when the blockage is in the second passage, the maintenance platform 1 of the multi-layer lifting device 9 of the present application on the second floor can be selected, or the lifting platform 21 of the multi-layer lifting device 9 of the present application on the first floor can be used, as long as the height is appropriate; when there are multiple blockages and they are not at the same height, the lifting components 2 of the multi-layer lifting device 9 of the present application can be adjusted separately, and each maintenance platform 1 can be matched one by one with each blockage. After determining the maintenance platform 1 whose height is to be adjusted, one operator is asked to climb onto the maintenance platform 1 first, and then another operator is asked to raise the height of the corresponding maintenance platform 1 to the height of the blockage by adjusting the lifting assembly 2. Then, the operator lying on the maintenance platform 1 uses the lifting platform 21 as a fulcrum to slide the maintenance platform 1 out, and hangs the maintenance platform 1 between the passage to be dredged and the lifting assembly 2, and locks the moving parts 31. Finally, the operator can dredge the blockage on the maintenance platform 1.
