Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of storage equipment, especially a storage device. BACKGROUND

[0002] The storage device is a basic unit of the storage equipment for realizing temporary storage of materials. Specifically, the storage device can be a fixed storage device placed in a predetermined station or workshop, or a transfer storage device installed on a movable chassis. For materials with low cleanliness requirements or low safety requirements, an open or semi-closed storage device can be used for material storage. For materials with high cleanliness requirements or high safety requirements, a closed storage device is required for storage. Specifically, a side door is provided on one side of the storage device, which can be opened and closed. When the material needs to be stored or taken out, the side door is opened. After the storage is completed or the material is completely taken out, the side door is closed. Common side doors mainly include a translational structure and a rotating hinged structure. Among them, the translational side door structure is simple and easy to control, so it is widely used. The translational side door in the prior art is usually driven by a linear module to open or close the side door. A stroke control module is configured to control the stroke of the side door translation. For example, a travel switch, when the side door moves to the position and touches the travel switch, the side door stops.

[0003] However, the prior art has the disadvantage that when the travel switch fails, the side door cannot receive the control signal after moving to the position, causing the linear module to continue driving the side door to move and causing interference and even the risk of colliding with the storage device. Although a limiting piece can be used to limit it, such as a limiting block at the end of the guide rail. Although this method can alleviate the consequences of the impact problem to some extent, it still has certain risks, such as damage to the driving mechanism of the linear module.

Among them, door body 20 is used to open or close storage box body 1.Lifting follower 21 is used to obtain external force driving to realize the lifting of door body 20.For this embodiment, both sides of door body 20 are equipped with one lifting follower 21, so that door body 20 is evenly driven by external force, and stable lifting is realized.

[0031] Referring to Figure 1 And Figure 2As shown, the driving assembly 3 is arranged on the storage box 1. The driving assembly 3 is used to provide stable external force for the lifting door assembly 2 to realize the lifting of the lifting door assembly 2. Specifically, the driving assembly 3 includes a driving motor 30 arranged on the storage box 1, and a first rotating shaft 31 connected with the output end of the driving motor 30. Wherein, the two ends of the first rotating shaft 31 are horizontally arranged on the storage box through a bearing with seat. The bearing with seat herein is defined as the first bearing with seat 55. As a preferred embodiment, the output end of the driving motor 30 is further provided with a shaft coupling 32. The first rotating shaft 31 is connected with the output end of the driving motor 30 through the shaft coupling 32.

[0032] The lifting assembly 4 is connected with the driving assembly 3. Specifically, the lifting assembly 4 includes a lifting traction member 40 connected with the driving assembly 3. And the lifting traction member 40 is further connected with the lifting door assembly 2. For this embodiment, the lifting assembly 4 is provided with two groups, which are arranged on the two sides of the storage box 1 respectively. And the lifting traction member 40 of each group of the lifting assembly 4 is connected with the lifting follower 21 on the two sides of the door body 20 respectively. Through the driving of the driving assembly 3, the lifting traction member 40 can be circularly moved along the height direction of the storage box 1, so as to make the lifting door assembly 2 lift along the storage box 1.

[0033] In this embodiment, the lifting door assembly 2 is connected with the lifting traction member 40 through the lifting chain 43. When the first lifting gear 41 is driven to rotate, the lifting chain 43 is circularly moved, so as to drive the lifting traction member 40 to circularly move along the height direction, thereby driving the lifting door assembly 2 to lift. Figure 2 As shown, each group of the lifting assembly 4 further includes a first lifting gear 41, a second lifting gear 42 and a lifting chain 43. The first lifting gear 41 and the second lifting gear 42 of each group of the lifting assembly 4 are arranged along the height direction and rotatably arranged on the same side of the storage box 1. The lifting chain 43 is wound around the first lifting gear 41 and the second lifting gear 42 to form a ring-shaped transmission structure. The lifting door assembly 2 is connected with the lifting chain 43 through the lifting traction member 40. Thus, when the first lifting gear 41 is driven to rotate, the lifting chain 43 is circularly moved, so as to drive the lifting traction member 40 to circularly move along the height direction, thereby driving the lifting door assembly 2 to lift. Therefore, the first lifting gear 41 is in transmission connection with the driving assembly 3.

[0034] The storage device in this embodiment further includes a transmission assembly 5. The transmission assembly 5 includes a first transmission gear 51 and a second transmission gear 52 rotatably arranged on the storage box 1, and a transmission chain 53 wound around the first transmission gear 51 and the second transmission gear 52. Wherein, the first transmission gear 51 is connected with the driving assembly 3 to obtain power input. Specifically, the first transmission gear 51 is coaxially connected with the first rotating shaft 31 of the driving assembly 3. The second transmission gear 52 is coaxially connected with the first lifting gear 41. When the driving motor 30 drives the first transmission gear 51 to rotate through the first rotating shaft 31, the first transmission gear 51 drives the second transmission gear 52 to rotate through the transmission chain 53, thereby realizing the rotation of the first lifting gear 41.

[0035] In a further embodiment, the drive assembly 3 further comprises a one-way bearing coaxially arranged with the first rotating shaft 31. The first transmission gear 51 is coaxially connected with the first rotating shaft through the one-way bearing. The one-way bearing is defined as the first one-way bearing 54. This arrangement ensures that the first transmission gear 51 rotates in one direction, thereby enabling the lifting assembly 4 to move in one direction, and further enabling the lifting traction 40 to move in one direction, preventing the lifting door assembly 2 from reversing during the lifting process, and improving the safety of the lifting door assembly 2 during the lifting process.

The seat bearings are defined as the second seat bearings 57. The second seat bearings 57 are mounted on the storage box 1. The second transmission gear 52 is coaxially connected with the second rotating shaft 56. The first lifting gear 41 is also coaxially connected with the second rotating shaft 56. Preferably, the second transmission gear 52 and the first lifting gear 41 are fixedly connected with the second rotating shaft 56. Therefore, when the first transmission gear 51 rotates, the second transmission gear 52 is driven to rotate through the transmission chain 53, thereby synchronously rotating the second rotating shaft 56 and the first lifting gear 41.

[0037] As mentioned above, the lifting assembly 4 in the present embodiment can be provided in two sets. Therefore, the two first lifting gears 41 of the two sets of lifting assemblies 4 are coaxially arranged at both ends of the second rotating shaft 56. In this way, the two sets of lifting assemblies 4 can be synchronously lifted, thereby keeping the lifting door assembly 2 stable during the lifting process.

The connecting portion 211 is provided with a mounting hole, and the door body 20 is fixedly connected with the connecting portion 211 through a fastening bolt.​

[0039] For how the traction block is connected with the lifting chain 43, the embodiment will be further described. In combination with Figure 3 and Figure 4 , the lifting assembly 4 further comprises a chain link connector 44 connected with the lifting chain 43. The traction block of the lifting traction 40 is connected with the lifting chain 43 through the chain link connector 44. For the lifting chain 43, it comprises a plurality of chain units, and the chain link connector 44 in the embodiment is connected between two chain units. Specifically, the chain link connector 44 comprises a chain link body 440, and a chain link pin 441 and a chain link fixing portion 442 connected with the chain link body 440. Among them, the chain link body 440 is installed on the traction block through the chain link fixing portion 442. The chain link body 440 is connected with the lifting chain 43 through the chain link pin 441.

[0040] Referring to Figure 2 and Figure 3 , in a further embodiment, during the circulation movement of the lifting chain 43, the lifting traction 40 has a high point position and a low point position; when the lifting traction 40 rises to the high point position, the lifting door assembly 2 closes the storage box body 1; when the lifting traction 40 rises to the low point position, the lifting door assembly 2 opens the storage box body 1. In order to solve the imbalance problem of the lifting traction 40 at the highest point position and the lowest point position, especially the imbalance problem at the highest point, in the embodiment, the aforementioned high point position and low point position have certain setting requirements, specifically, the angle between the high point position and the first lifting gear 41 rotation shaft axis and the vertical direction is kept at about 5°. Of course, for the low point position, the angle between the low point position and the second lifting gear 42 rotation shaft axis and the vertical direction is kept at about 5°.

[0041] In combination with Figure 3 , in a further embodiment, the lifting assembly 4 further comprises a third rotation shaft 45 and a second one-way bearing 46 connected with the third rotation shaft 45. The third rotation shaft 45, the second one-way bearing 46 and the second lifting gear 42 are coaxially connected. In this way, the second lifting gear 42 can only rotate in one direction, avoiding the door body 20 from moving in the opposite direction due to power loss during lifting, thereby reducing the risk of operation safety.

[0042] As a preferred embodiment, the storage device further comprises a guide assembly 6, which comprises a guide rail 60 arranged on the storage box body 1 in the height direction, and a sliding block 61 slidingly connected with the guide rail 60, the sliding block 61 being connected with the lifting door assembly 2.

[0043] In conclusion, the storage device provided in the embodiment can drive the lifting traction member 40 to move circularly along the height direction through the driving assembly 3, so as to drive the lifting door assembly 2 to lift to realize the opening and closing of the storage box 1. Since the lifting traction member 40 can naturally form a high point and a low point during the movement, the closing and opening of the lifting door assembly 2 are corresponded, the storage device of the utility model does not need to be provided with a limiting mechanism, so as to simplify the structure of the storage device, and the problem of interference or impact can be avoided, so as to avoid the damage of the structure of the driving assembly, effectively reduce the safety risk, and make the opening and closing control process of the lifting door assembly 2 more simple.
