Description

Technical Field

[0001] This application relates to the field of mechanical equipment technology, and in particular to a lifting mechanism. Background Technology

[0002] Elevators are common lifting equipment, mostly used on assembly lines. To meet different needs, the products being produced are frequently modified. If the products to be lifted are too large, the outer frame of the elevator also needs to be very large, resulting in excessive space occupation. Utility Model Content

[0003] This application provides a lifting mechanism to at least partially solve the technical problem of excessive space occupation caused by the lifting machine needing to lift excessively large products.

[0004] To achieve the above objectives, this application provides a lifting mechanism, comprising:

[0005] Multiple lifting components, with adjacent lifting components detachably connected;

[0007] In some embodiments, the lifting assembly includes a lifting assembly and a transmission assembly, the lifting assembly and the transmission assembly are connected by a drive, the transmission assemblies of two adjacent lifting assemblies are detachably connected, and the drive assembly is connected to at least one transmission assembly.

[0008] In some embodiments, the transmission assembly includes a first transmission member and a first transmission shaft;

[0009] The first transmission component is connected to the first transmission shaft and the lifting assembly respectively. Two adjacent first transmission shafts are detachably connected. The drive assembly is connected to at least one first transmission shaft and is used to drive the first transmission shaft to rotate.

[0010] In some embodiments, the lifting mechanism includes a universal joint that detachably connects two adjacent first drive shafts.

[0011] In some embodiments, the drive assembly includes a motor and a coupling, with the output of the motor connected to a first drive shaft via the coupling.

[0013] The second drive shaft and the first drive shaft are spaced apart along the first direction, and the first drive component is respectively connected to the first drive shaft and the second drive shaft.

[0014] The second and third drive shafts are spaced apart along the second direction, and the second drive component is connected to the second and third drive shafts respectively. The first direction intersects the second direction.

[0015] In some embodiments, the lifting component includes a plurality of second transmission members, which are spaced apart along a third direction. One second transmission member is connected to a third transmission shaft, and the third direction intersects with the first direction and the second direction, respectively.

[0016] In some embodiments, the lifting component includes a plurality of second transmission members, which are spaced apart along a third direction and are connected to a third transmission shaft. The third direction intersects the first direction and the second direction, respectively.

[0017] In some embodiments, the lifting mechanism includes a lifting carrier, which is mounted on a second transmission member, which drives the lifting carrier to move in a second direction.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0034] The applicant noted that hoists are common lifting equipment. Normally, a single hoist is driven by a motor, and its frame is also a single unit. In special cases, if the product to be lifted is too large, a larger hoist frame is required, resulting in excessive space occupation. Currently, hoists used in factories are mostly on assembly lines. To meet different needs, product changes are frequent, requiring corresponding modifications to the assembly line. Building an excessively large hoist specifically for producing a large product leads to significant waste of space and energy if smaller products are needed later. Conversely, if the initially built hoist is small but needs to be upgraded to a larger one, the entire frame needs to be rebuilt, resulting in waste.

[0035] In view of this, this application provides a lifting mechanism, including multiple lifting components 1 and a drive component 2, with adjacent lifting components 1 detachably connected; the drive component 2 is connected to at least one lifting component 1 and is used to drive at least one lifting component 1 to move. This application, by setting multiple lifting components 1 and arranging the drive component 2 on one lifting component 1, allows for lifting when the material to be lifted is large, as multiple lifting components 1 are connected by transmission, enabling lifting through a single drive component 2; when the material to be lifted is small, excess lifting components 1 are disassembled, and the remaining lifting components 1 are lifted through a single drive component 2. This configuration allows for rapid production line changeover, shortening equipment modification costs and timelines. The overall size of the lifting mechanism can be flexibly adjusted by increasing or decreasing the number of lifting components 1, effectively solving the space occupation problem caused by changes in product size in traditional lifting machines. Multiple lifting components 1 sharing a single power source reduces manufacturing costs and simplifies the maintenance process of the lifting mechanism.

[0036] The lifting mechanism of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can be combined with each other.

[0038] ReferenceFigure 2 and Figure 3 This application provides a lifting mechanism, including multiple lifting components 1 and a drive component 2. Adjacent lifting components 1 are detachably connected. The drive component 2 connects to at least one lifting component 1 and drives the at least one lifting component 1 to move. By setting multiple lifting components 1 and arranging the drive component 2 on one lifting component 1, when the material to be lifted is large, the multiple lifting components 1 are connected, allowing lifting to be achieved by a single drive component 2. When the material to be lifted is small, the excess lifting components 1 are disassembled, and the remaining lifting components 1 are lifted by a single drive component 2. This configuration allows for rapid production line changeover, shortening equipment modification costs and timelines. The overall size of the lifting mechanism can be flexibly adjusted by increasing or decreasing the number of lifting components 1, effectively solving the space occupation problem caused by changes in product size in traditional lifting machines. Multiple lifting components 1 sharing a single power source reduces manufacturing costs and simplifies the maintenance process of the lifting mechanism.

[0039] In some embodiments, refer to Figure 3 The lifting assembly 1 includes a lifting component 10 and a transmission component 11, which are connected by a drive mechanism. The transmission components 11 of two adjacent lifting assemblies 1 are detachably connected. A drive component 2 connects to at least one transmission component 11. It can be understood that the lifting assembly 10 is directly responsible for the lifting function of materials, while the transmission component 11 acts as a transitional transmission element, enabling linkage between adjacent lifting assemblies 1. Specifically, one transmission component 11 is connected to both the lifting assembly 10 and the drive component 2, and the remaining transmission components 11 can be connected to the transmission component 11 equipped with the drive component 2. This ensures that power is stably transmitted from the drive component 2 to each lifting assembly 10, avoiding energy loss and synchronization errors that may result from multi-stage transmission. Adjacent lifting assemblies 1 can be quickly connected or disconnected through adjacent transmission components 11. Lifting assemblies 10 can be added or removed without adjusting the drive system, thus quickly completing production line changeovers and shortening equipment modification costs and cycles.

[0040] In some embodiments, refer to Figure 4 The transmission assembly 11 includes a first transmission member 110 and a first transmission shaft 111. The first transmission member 110 is connected to both the first transmission shaft 111 and the lifting assembly 10. Two adjacent first transmission shafts 111 are detachably connected. The drive assembly 2 is connected to at least one first transmission shaft 111 and is used to drive the first transmission shaft 111 to rotate. The first transmission member 110 includes a transition chain, a first main sprocket, and a first auxiliary sprocket. Rotation of the first transmission shaft 111 can drive the first main sprocket to rotate. The first main sprocket drives the first auxiliary sprocket through the transition chain. The first auxiliary sprocket is disposed on the lifting assembly 10, thereby realizing the drive assembly 2 to drive the transmission assembly 11 and the lifting assembly 10.

[0041] In some embodiments, refer to Figure 6 The lifting mechanism includes a universal joint 3, which detachably connects two adjacent first drive shafts 111. The connection of adjacent first drive shafts 111 via the universal joint 3 allows for a certain degree of axial deflection and displacement, reducing the alignment accuracy requirements during assembly. When adding or removing lifting components 1, simply disconnecting or connecting the universal joint 3 is sufficient to align the first drive shafts 111, eliminating the need for precise calibration and significantly shortening equipment adjustment time. Furthermore, the flexible connection characteristics of the universal joint 3 can compensate for axial deviations caused by frame deformation or installation errors, avoiding additional stress that may result from rigid connections and extending the service life of the drive shafts and bearings. The universal joint 3 can be replaced independently, reducing maintenance costs.

[0042] In some embodiments, refer to Figure 6 The drive assembly 2 includes a motor 20 and a coupling 21. The output end of the motor 20 is connected to the first drive shaft 111 via the coupling 21. The motor 20 directly drives the first drive shaft 111 through the coupling 21, reducing energy loss in intermediate transmission links and ensuring efficient power transmission to the transmission assembly 11 and the lifting assembly 10. The coupling 21 can buffer the impact of the motor 20 starting and stopping or sudden load changes, reducing mechanical vibration and extending the service life of the equipment. As a standardized component, the coupling 21 is easy to replace and can be replaced individually without affecting the motor 20 or the first drive shaft 111, reducing maintenance difficulty and cost.

[0043] In some embodiments, refer to Figure 4 and Figure 5 The lifting assembly 10 includes a second transmission member 100, a second transmission shaft 101, and a third transmission shaft 102. The second transmission shaft 101 and the first transmission shaft 111 are spaced apart along a first direction X. The first transmission member 110 is connected to the first transmission shaft 111 and the second transmission shaft 101 respectively. The first transmission member 110 includes a transition chain, a first main sprocket, and a first auxiliary sprocket. The rotation of the first transmission shaft 111 can drive the first main sprocket to rotate. The first main sprocket drives the first auxiliary sprocket through the transition chain. The first auxiliary sprocket is located on the second transmission shaft 101, thereby driving the second transmission shaft 101 to rotate.

[0044] In some embodiments, refer to Figure 4 and Figure 5The second drive shaft 101 and the third drive shaft 102 are spaced apart along the second direction Y. The second drive member 100 connects the second drive shaft 101 and the third drive shaft 102. The first direction X intersects the second direction Y. The first drive member 110 extends along the first direction X, which can be horizontal or inclined relative to the horizontal direction. The second drive member 100 extends along the second direction Y, which can be vertical or inclined relative to the vertical direction. It is understood that the second drive shaft 101 is positioned at a lower position, and the third drive shaft 102 is positioned at a higher position. The second drive member 100 includes a lifting chain, a second main sprocket, and a second auxiliary sprocket. The second main sprocket is located on the second drive shaft 101, and the second auxiliary sprocket is located on the third drive shaft 102. Rotation of the second drive shaft 101 drives the second main sprocket to rotate. The second main sprocket drives the second auxiliary sprocket through the lifting chain, and the second auxiliary sprocket drives the third drive shaft 102 to rotate. The multi-point meshing characteristic of chain drives further disperses the load, reduces local stress concentration, and thus extends the service life of sprockets and chains.

[0045] In some embodiments, refer to Figure 6 The lifting assembly 10 includes multiple second transmission components 100, which are spaced apart along a third direction Z. Each second transmission component 100 is connected to a third transmission shaft 102. The third direction Z intersects with the first direction X and the second direction Y. The multiple second transmission components 100 form a chain drive system arranged parallel to each other along the third direction Z, distributing the lifting force to multiple points. This arrangement avoids the off-center load problem that may occur with single-chain drives, ensuring that the lifting assembly 10 remains horizontal during material lifting, and is suitable for lifting needs of large-sized or asymmetrical loads.

[0046] In other embodiments, multiple second transmission components 100 are connected to a third transmission shaft 102, forming a chain drive system arranged parallel to each other along the third direction Z, thus distributing the lifting force to multiple points. This configuration avoids the off-center load problem that may occur with single-chain drives, ensuring that the lifting assembly 10 remains horizontal during material lifting, and is suitable for lifting needs of large-sized or asymmetrical loads.

[0047] In some embodiments, refer to Figure 2 The lifting mechanism includes a lifting carrier 4, which is mounted on a second transmission component 100. The second transmission component 100 drives the lifting carrier 4 to move in the second direction Y. The lifting carrier 4 is connected to the lifting chain of the second transmission component 100 through a multi-point fixing method. When the lifting chain rotates, it can drive the lifting carrier 4 to move along the second direction Y, thereby realizing the lifting of materials on the lifting carrier 4.

[0048] In some embodiments, refer toFigure 1 and Figure 2 The lifting mechanism comprises multiple main frames 5, with a lifting component 1 mounted on each main frame 5. Each lifting component 1 uses an independent main frame 5. When the material to be lifted is large, the main frames 5 of multiple lifting components 1 can be spliced ​​together, and adjacent lifting components 1 are connected by a drive mechanism, enabling lifting via a single drive component 2. When the material to be lifted is small, the excess main frames 5 and the lifting components 1 within them can be disassembled, and the remaining lifting components 1 are lifted via a single drive component 2. This configuration allows for rapid production line changeover, shortening equipment modification costs and timelines. The overall size of the lifting mechanism can be flexibly adjusted by increasing or decreasing the number of lifting components 1, effectively solving the space occupation problem caused by changes in product size in traditional lifting machines. It also improves the modularity and deployment flexibility of the lifting mechanism.

[0049] In some embodiments, the lifting mechanism includes a plurality of bearing seats 6; the lifting assembly 1 is rotatably connected to the main frame 5 via the bearing seats 6. Specifically, refer to Figure 2 and Figure 3 The lifting assembly 1 includes a lifting assembly 10 and a transmission assembly 11. The transmission assembly 11 includes a first transmission shaft 111, and the lifting assembly 10 includes a second transmission shaft 101 and a third transmission shaft 102. The first transmission shaft 111, the second transmission shaft 101, and the third transmission shaft 102 are rotatably connected to the main frame 5 via bearing seats 6. The first transmission shaft 111, the second transmission shaft 101, and the third transmission shaft 102 are fixed to the main frame 5 via independent bearing seats 6, which optimizes the stability and ease of maintenance of the lifting mechanism.
