Description

Technical Field

[0001] This invention relates to the field of stacker crane technology, specifically to an automated high-speed stacker crane with an emergency stop buffer function. Background Technology

[0002] Stacker cranes are a type of cargo storage and retrieval equipment used in automated warehouses. They achieve efficient and precise cargo handling through mechanical structures and are the core equipment of automated warehouses. They are mainly used to move back and forth between warehouse aisles to realize cargo storage and retrieval operations.

[0003] A Chinese invention with application publication number CN118515097B discloses a high-speed bin stacker, including a base box, a vertical frame fixedly connected to the top of the bottom of the base box, a sliding seat slidably sleeved on the outside of the vertical frame, a support plate fixedly installed on one side of the sliding seat, and guide rails fixedly connected to the front and rear sides of the bottom of the base box; a drive mechanism is used to drive the sliding seat to lift and lower, and a counterweight mechanism is used to adjust the center of gravity position of the base box.

[0004] However, the inventors discovered that in actual use, when the stacker crane stops suddenly, adjusting the position of its counterweight only through the base has little effect on the goods that have moved to the top. Based on this, we proposed an automated high-speed stacker crane with an emergency stop buffer function. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies. By providing a platform on one side of the vertical rail, a buffer plate is slidably mounted on the platform, and an electromagnetic induction device is installed between the buffer plate and the platform. A load-bearing box is located on the other side of the vertical rail, containing a counterweight. A linkage component is installed inside the vertical rail. When the stacker crane stops suddenly, the goods on the platform will generate an impact force due to inertia, causing the electromagnetic induction device to disconnect. As the buffer plate slides on the platform, the counterweight moves in the opposite direction under the drive of the linkage component, balancing the forward impact force of the goods, preventing the stacker crane from tipping over, and ensuring the stability of the goods.

[0006] To address the aforementioned technical problems, the present invention adopts the following technical solution:

[0007] An automated high-speed stacker crane with an emergency stop buffer function includes a base, a vertical rail fixedly connected to the top of the base, a platform slidably disposed on one side of the vertical rail, a buffer plate slidably disposed on the platform, an electromagnetic induction between the buffer plate and the platform, a load-bearing box disposed on the other side of the vertical rail, a counterweight disposed inside the load-bearing box, and a linkage component disposed inside the vertical rail, the linkage component being used to drive the buffer plate and the counterweight to move relative to each other or move away from each other.

[0008] As a preferred embodiment, the linkage assembly includes a first slide groove disposed inside the vertical rail, a movable block slidably disposed within the first slide groove, a rotating shaft rotatably disposed within the movable block, a gear fixedly disposed on the rotating shaft, and a first rack and a second rack respectively disposed at the upper and lower ends of the gear and meshing with the gear.

[0009] As a preferred embodiment, the first rack is fixedly connected to the lower end face of the buffer plate, and the second rack is fixedly connected to the upper end face of the counterweight.

[0010] As a preferred embodiment, the lower end of the counterweight is evenly distributed with rotating wheels, and a track is provided inside the load-bearing box, in which the rotating wheels roll and move.

[0011] As a preferred embodiment, the outer surface of the vertical rail is provided with two parallel sliding grooves, and the platform and the load-bearing box are respectively slidably disposed in the sliding grooves.

[0012] As a preferred embodiment, the upper surface of the platform is provided with a T-shaped groove, and the lower end face of the buffer plate is provided with a T-shaped protrusion, the T-shaped protrusion being slidably disposed within the T-shaped groove.

[0013] As a preferred embodiment, the movable block is provided with support rods at both its upper and lower ends, and the support rods are fixedly connected to the platform and the load-bearing box, respectively.

[0014] As another preferred embodiment, a lead screw is provided through the platform, and a drive motor is provided at the upper end of the vertical rail, the drive motor being used to drive the lead screw to rotate.

[0015] The beneficial effects of this invention are:

[0016] In this invention, the buffer plate and the counterweight are linked together. When the stacker crane stops suddenly, the cargo on the platform will generate an impact force due to inertia, causing the electromagnetic induction to disconnect. When the buffer plate slides on the platform, the counterweight moves in the opposite direction under the drive of the linkage component, balancing the forward impact force of the cargo, preventing the stacker crane from tipping over and ensuring the stability of the cargo.

[0017] In summary, this equipment has advantages such as stable center of gravity and buffer function, and is especially suitable for the field of stacker crane technology. Attached Figure Description

Detailed Implementation

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figures 1 to 8 As shown, an automated high-speed stacker crane with an emergency stop buffer function includes a base 1. A vertical rail 2 is fixedly connected to the top of the base 1. A platform 3 is slidably arranged on one side of the vertical rail 2. A buffer plate 4 is slidably arranged on the platform 3. An electromagnetic induction device 5 is arranged between the buffer plate 4 and the platform 3. A load-bearing box 6 is arranged on the other side of the vertical rail 2. A counterweight 7 is arranged inside the load-bearing box 6. A linkage component 8 is arranged inside the vertical rail 2. The linkage component 8 is used to drive the buffer plate 4 and the counterweight 7 to move relative to each other or move away from each other.

[0031] like Figures 2 to 5As shown, the linkage component 8 includes a first slide groove 81 disposed inside the vertical rail 2, a movable block 82 slidably disposed within the first slide groove 81, a rotating shaft 83 rotatably disposed within the movable block 82, a gear 84 fixedly disposed on the rotating shaft 83, and a first rack 85 and a second rack 86 respectively disposed at the upper and lower ends of the gear 84 and meshing with the gear 84. The first rack 85 is fixedly connected to the lower end face of the buffer plate 4, and the second rack 86 is fixedly connected to the upper end face of the counterweight block 7.

[0032] In this embodiment, the first rack 85 moves to drive the gear 84 to rotate, which in turn drives the second rack 86 to move in the opposite direction, causing the counterweight 7 under the second rack 86 to move in the opposite direction to the buffer plate 4.

[0033] like Figure 6 As shown, the lower end of the counterweight 7 is evenly distributed with rotating wheels 71, and the load-bearing box 6 is provided with a track 61, and the rotating wheels 71 roll and move within the track 61.

[0034] It is worth mentioning that the counterweight 7 is relatively heavy, and it slides within the track 61 via the rotating wheel 71, which facilitates the movement of the counterweight 7.

[0035] like Figure 7 As shown, the outer surface of the vertical rail 2 is provided with two parallel sliding grooves 21, and the platform 3 and the load-bearing box 6 are respectively slidably disposed in the sliding grooves 21.

[0036] like Figure 8 As shown, the upper surface of the platform 3 is provided with a T-shaped groove 31, and the lower end face of the buffer plate 4 is provided with a T-shaped protrusion 41. The T-shaped protrusion 41 is slidably disposed in the T-shaped groove 31.

[0037] like Figure 3 As shown, the movable block 82 is provided with support rods 87 at both the upper and lower ends, and the support rods 87 are fixedly connected to the platform 3 and the load-bearing box 6 respectively.

[0038] It is worth mentioning that, through the setting of the support rods 87 at both ends, the platform 3 moves synchronously, driving the moving block 82 and the load-bearing box 6 to move synchronously.

[0039] like Figure 7 As shown, a lead screw 22 is installed through the platform 3, and a drive motor 23 is installed at the upper end of the vertical rail 2. The drive motor 23 is used to drive the lead screw 22 to rotate.

[0040] In this embodiment, the drive motor 23 drives the lead screw 22 to rotate, the platform 3 is limited within the vertical rail 2, and the platform 3 moves longitudinally within the vertical rail 2.

[0041] The work process is as follows:

[0042] Start the drive motor 23, drive the lead screw 22 to rotate, and drive the platform 3 to move longitudinally within the vertical rail 2. Through the connection of the support rod 87, the moving block 82 and the load-bearing box 6 move synchronously.

[0043] When the stacker crane stops suddenly, the buffer plate 4 carrying the load will generate an impact force due to inertia. When this impact force is greater than the attraction force of the electromagnetic induction 5, the first rack 85 drives the buffer plate 4 to move forward, drives the gear 84 to rotate, drives the second rack 86 to move in the opposite direction, and drives the counterweight 7 under the second rack 86 to move in the opposite direction to the buffer plate 4.

[0044] When the inertial force disappears, the first rack 85 will retract with the buffer plate 4, and the attraction force of the electromagnetic induction 5 will cause the buffer plate 4 to re-attach to the platform 3.

[0045] Of course, those skilled in the art should understand that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple. The term "a" should not be understood as a limitation on the quantity.

[0046] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art under the technical guidance of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
