Description

Technical Field

[0001] This utility model relates to the field of workpiece storage and transportation technology, and in particular to a lifting basket for a hoist. Background Technology

[0002] To save storage space and reduce the difficulty of accessing and retrieving workpieces, the concept of automated warehouses has been further developed. Automated warehouses typically have storage racks. To move or retrieve workpieces onto or from the racks, they also include a hoist that works in conjunction with the racks. The hoist consists of a frame, a lifting mechanism, and a basket. The basket carries a pallet containing the workpieces. Under the action of the lifting mechanism, the basket can move up and down on the frame, thereby lifting the workpieces to different heights.

[0003] However, existing hoists are only suitable for storage racks with powered connection structures and are difficult to connect with storage racks without powered connection structures, thus limiting their applicability. Utility Model Content

[0004] The purpose of this utility model is to provide a basket for a hoist that can solve the problems of hoists being difficult to connect with storage racks without power connection structures and having a limited range of applications.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A hoist basket includes a mounting bracket and a sprocket drive assembly. The sprocket drive assembly includes a drive sprocket, a driven sprocket, a drive chain, a connecting drive component, and a material hook. The drive sprocket and the driven sprocket are rotatably mounted on the mounting bracket at intervals along a horizontally positioned first direction. The connecting drive component is connected to the drive sprocket. The drive chain is wound around the drive sprocket and the driven sprocket, and both ends of the drive chain are connected to the material hook to form a closed loop. The material hook is used to hook a material tray.

[0007] Optionally, the material hook includes a connecting part and a hooking part. The connecting part is connected to the drive chain, and one end of the hooking part is connected to the connecting part, while the other end extends along the first direction and has a hook groove.

[0008] Optionally, the drive chain is a double-row chain.

[0009] Optionally, two sprocket drive assemblies are provided at intervals along a second direction on the mounting bracket, the second direction being a horizontal direction perpendicular to the first direction.

[0010] Optionally, the drive sprockets of the two sprocket drive assemblies are connected via the same shaft.

[0011] Optionally, the sprocket drive assembly further includes a proximity sensor that is communicatively connected to the connecting drive component. The proximity sensor is used to monitor the position of the material hook, and the mounting bracket is provided with the proximity sensor on both sides along the first direction.

[0012] Optionally, the lifting basket for the elevator further includes a support assembly, the height of which is the same as the height of the conveying surface of the drive chain.

[0013] Optionally, the support assembly includes a roller seat and driven rollers, the roller seat is fixedly mounted on the mounting bracket, and a plurality of driven rollers are rotatably mounted on the roller seat at intervals along the first direction.

[0014] Optionally, the lifting basket for the hoist further includes two guide components symmetrically arranged on the mounting bracket along the second direction. Each guide component includes a sliding seat and a first guide wheel set. The sliding seat is fixedly arranged on the mounting bracket, and the two sets of first guide wheel sets are rotatably arranged on the sliding seat at intervals to cooperate in clamping the frame of the hoist. Each first guide wheel set includes at least two first guide wheels arranged at intervals along the vertical direction.

[0015] Optionally, the guide assembly further includes a second guide wheel disposed on the sliding seat, the second guide wheel being disposed between the two sets of the first guide wheel sets and the rotation axis of the second guide wheel being perpendicular to the rotation axis of the first guide wheel.

[0016] The beneficial effects of this utility model are as follows: The drive chain in the hoist basket of this utility model can reciprocate along a first direction under the action of the connecting drive component. The material pull hook can engage with the limiting groove on the material tray, and then pull the material tray along with the drive chain to move away from the initial position to the target position until the material tray is transferred to the target position. Then the basket descends, and the material pull hook can disengage from the material tray. The above-mentioned hoist basket can pick up and place workpieces on both storage racks with and without a power connection structure, making the hoist more adaptable and compatible. Moreover, by using the material pull hook to connect the two ends of the drive chain, it is equivalent to saving one link of the drive chain, making the structure more compact, the connection between the material pull hook and the drive chain tighter, and the structural strength higher.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0026] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0029] refer to Figures 1-5 As shown, an embodiment of this utility model proposes a lifting basket for a hoist, including a mounting bracket 1 and a sprocket drive assembly 2. The sprocket drive assembly 2 is mounted on the mounting bracket 1 and includes a driving sprocket 25, a driven sprocket 26, a drive chain 21, a connecting drive component 22, and a material hook 23. The driving sprocket 25 and the driven sprocket 26 are each connected by a rotating shaft along a horizontally positioned first direction (…). Figure 1 and Figure 2 The drive chain 21 is rotatably mounted on the mounting bracket 1 in the X direction (i.e., the direction of material transfer). The drive component 22 is connected to the drive sprocket 25 to drive the drive sprocket 25 to rotate. The drive chain 21 is wound around the drive sprocket 25 and the driven sprocket 26. Both ends of the drive chain 21 are connected to the pull hook 23 to form a closed loop. The pull hook 23 can pull the material pallet by engaging with the limiting groove set on the material pallet where the workpiece is located.

[0030] The drive chain 21 in the aforementioned hoist basket can reciprocate along a first direction under the action of the connecting drive component 22. The material hook 23 can engage with the limiting groove on the material tray, and then pull the material tray along with the drive chain 21 to move away from the initial position to the target position until the material tray is transferred to the target position. Then the basket descends, and the material hook 23 can disengage from the material tray. It can be understood that this process can be either transferring the material tray from the hoist basket to the storage rack for storing workpieces, or removing the workpiece from the storage rack. With the setting of the sprocket transmission assembly 2, the aforementioned hoist basket can pick up and place workpieces on both storage racks with and without a powered connecting structure, making the hoist more adaptable and compatible. Moreover, by using the material hook 23 to connect the two ends of the drive chain 21, it is equivalent to saving one drive chain link of the drive chain 21, making the structure more compact, and the connection between the material hook 23 and the drive chain 21 is tighter, resulting in higher structural strength.

[0031] refer to Figure 4As shown, in this embodiment, the material hook 23 includes a connecting part 231 and a hooking part 232. The connecting part 231 is connected to the drive chain 21. One end of the hooking part 232 is connected to the connecting part 231, and the other end extends along the first direction. The hooking part 232 has a hook groove 233 at the end away from the connecting part 231. The side wall of the groove away from the connecting part 231 of the hook groove 233 acts as a claw to cooperate with the limiting groove on the material tray to hook the material tray. The hooked material tray can contact the bottom of the groove 233. Compared with setting the material hook 23 directly as an L-shape, the tilt of the material tray can be reduced while ensuring the connection strength between the material hook 23 and the drive chain 21. The workpiece on the material tray is less likely to slide on the material tray.

[0032] To further improve the stability of the connection between the pull hook 23 and the drive chain 21, the drive chain 21 adopts a double-row chain. Furthermore, to make efficient use of the space on the mounting bracket 1, two driven sprockets 26 are provided, located on opposite sides of the drive sprocket 25 along the first direction. The connecting drive component 22 connected to the drive sprocket 25 is located on the mounting bracket 1. Specifically, the sprocket transmission assembly also includes tension wheels 27. Tension wheels 27 are provided on opposite sides of the drive sprocket 25 along the first direction, and the tension wheels 27 and the drive sprocket 25 are located on the inner and outer sides of the chain, respectively. The distance between the two tension wheels 27 in the first direction is adjustable to adjust the tension of the drive chain 21.

[0033] refer to Figure 2 As shown, the sprocket drive assembly 2 is mounted on the mounting bracket 1 along the second direction ( Figure 1 and Figure 2 Two sprockets are spaced at intervals in the Y direction to improve stability when transferring material pallets. Specifically, to improve the consistency of movement between the two sprocket drive assemblies 2, the drive sprockets 25 of the two sprocket drive assemblies 2 are connected by the same shaft. The connecting drive 22 can be a servo motor, and the second direction is a horizontal direction perpendicular to the first direction.

[0034] In this embodiment, the sprocket drive assembly 2 further includes a proximity sensor 24 communicatively connected to the connecting drive component 22. The proximity sensor 24 is used to monitor the position of the material hook 23. The mounting bracket 1 is provided with proximity sensors 24 on both sides along the first direction. The two proximity sensors 24 correspond to the starting position and the ending position of the material hook 23, respectively. When one of the proximity sensors 24 senses the material hook 23, the connecting drive component 22 drives the drive sprocket 25 in the reverse direction, causing the drive chain 21 to move in the reverse direction. The starting position and the ending position refer to the extreme positions of the material hook 23 on opposite sides of the drive chain 21 in the first direction. When the material hook 23 is in one extreme position, the center of gravity of the material pallet can be completely transferred to the mounting bracket 1. When it is in the other extreme position, the center of gravity of the material pallet can be completely transferred to the storage rack.

[0035] To further improve the stability of material pallet transfer and reduce the load on the connecting drive component 22, the hoist basket also includes a support component 3. The support surface of the support component 3 is at the same height as the conveying surface of the drive chain 21. When the material pallet moves with the drive chain 21, it abuts against the support surface of the support component 3, and the support component 3 can support the material pallet.

[0036] In this embodiment, the support assembly 3 includes a roller seat 31 and driven rollers 32. The roller seat 31 is fixedly mounted on the mounting bracket 1, and multiple driven rollers 32 are rotatably mounted on the roller seat 31 at intervals along a first direction. The horizontal plane where the highest point of the driven rollers 32 is located is the support surface to support the material pallet. Because the driven rollers 32 are in rolling contact with the material pallet, the wear on the material pallet is small, and the service life of the material pallet is long. Specifically, the driven rollers 32 are disposed between two sprocket drive assemblies 2. In other embodiments, the support assembly 3 can also be a smooth-surfaced support plate, which will not be described in detail here.

[0037] refer to Figure 5 As shown, the hoist basket also includes two guide components 4, which are respectively disposed on both sides of the mounting bracket 1 along the second direction to improve the stability of the hoist basket during lifting and lowering. (Reference) Figure 4 As shown, the guide assembly 4 includes a sliding seat 41 and a first guide wheel set. The sliding seat 41 is fixedly mounted on the mounting bracket 1. Two sets of first guide wheels are rotatably mounted on the sliding seat 41 at intervals in the horizontal direction to form a clamping space for the frame 10 of the hoist. Each first guide wheel set includes at least two first guide wheels 42 that are spaced apart in the vertical direction. The third direction is the vertical direction.

[0038] Furthermore, the sliding seat 41 also includes a second guide wheel 43 disposed on the sliding seat 41. The second guide wheel 43 is positioned between the two sets of first guide wheels, and the rotation axis of the second guide wheel 43 is perpendicular to the rotation axis of the first guide wheel 42. The second guide wheel 43 also makes rolling contact with the frame 10. Thus, the first guide wheel sets and the second guide wheel 43 are respectively in contact with three sides of the frame 10, resulting in higher stability. Specifically, two second guide wheels 43 are also spaced apart in the third direction. For example, the rotation axis of the first guide wheel 42 extends along the second direction, and the rotation axis of the second guide wheel 43 extends along the first direction.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
