Description

Technical Field

[0001] This utility model relates to the field of anti-sway support for forks, and more particularly to an anti-sway support mechanism for stacker crane forks. Background Technology

[0002] Stacker cranes are the core equipment in automated storage and retrieval systems (AS / RS) used for storing, retrieving, and handling goods.

[0003] In automated storage and retrieval systems (AS / RS) and intelligent warehousing systems, stacker cranes are core storage and retrieval equipment. The operational stability of their forks directly affects the efficiency and safety of goods storage and retrieval. The forks need to perform complex actions such as lifting, extending, and retracting to move goods at different heights and positions.

[0004] Existing anti-sway designs for stacker crane forks have limitations: some solutions only restrict displacement through a single guide structure (such as a simple guide rail or roller), but this is difficult to compensate for manufacturing and installation gaps, and the sway suppression effect is limited when facing impact loads. Therefore, an anti-sway support mechanism for stacker crane forks is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a stacker crane fork anti-sway support mechanism, which aims to improve the problem of limited buffering effect and easy swaying in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a stacker crane fork anti-sway support mechanism, comprising a lower fork body, a groove formed on the upper inner wall of the lower fork body, a connecting block slidably connected to the inner wall of the groove, a middle fork body fixedly connected to the upper side of the connecting block, an upper fork body slidably connected to the inner wall of the middle fork body, a stabilizing component provided on the upper side of the upper fork body, a slider elastically connected to the inner wall of the groove by a spring, a connecting post fixedly connected to the front side of the slider, a sliding plate fixedly connected to the front side of the connecting post, a through hole formed on the inner wall of the sliding plate, and a tank body fixedly connected to the inner wall of the lower fork body.

[0007] As a further description of the above technical solution:

[0008] The stabilizing component includes an anti-slip strip, which is snapped onto the inner right side wall of the upper fork. A limit block is elastically connected to the inner upper side wall of the upper fork via two springs.

[0009] As a further description of the above technical solution:

[0010] One end of the second spring is fixedly connected to the upper inner wall of the upper fork, and the other end of the second spring is fixedly connected to the lower side of the limiting block.

[0011] As a further description of the above technical solution:

[0012] The upper right side of the limiting block is inclined, and the outer wall of the limiting block is slidably connected to the upper inner wall of the upper fork.

[0013] As a further description of the above technical solution:

[0014] One end of the spring is fixedly connected to the inner wall of the slide groove, and the other end of the spring is fixedly connected to the front side of the slider.

[0015] As a further description of the above technical solution:

[0016] The slider is trapezoidal in shape and is slidably connected to the inner wall of the groove.

[0017] As a further description of the above technical solution:

[0018] The connecting column is slidably connected to the rear inner wall of the tank.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the sliding plate is slidably connected to the inner wall of the tank, and the diameter of the sliding plate is larger than the diameter of the connecting column.

[0021] As a further description of the above technical solution:

[0022] The upper side of the anti-slip strip is slightly higher than the upper side of the upper fork, and a horizontal groove is provided on the upper side of the anti-slip strip.

[0023] As a further description of the above technical solution:

[0024] The groove is a trapezoidal groove.

[0025] This utility model has the following beneficial effects:

[0026] 1. In this utility model, the matching structure of the trapezoidal groove and the trapezoidal slider restricts the lateral displacement of the connecting block. The damping-elasticity cooperative structure formed by the tank buffer and the spring effectively buffers the sliding impact of the connecting block, reduces the relative sway of the middle fork and the lower fork, and improves the accuracy and dynamic stability of the fork extension and retraction.

[0027] 2. In this utility model, the anti-slip strip increases the friction with the goods through the raised design and horizontal groove structure. The limiting block tightened by the spring ensures that the anti-slip strip is firmly installed. The double protection can prevent the goods from sliding and the anti-slip strip from loosening, avoid the goods from shaking and causing the forks to swing, and improve the safety of goods storage and retrieval.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-3This utility model provides an embodiment of a stacker crane fork anti-sway support mechanism, including a lower fork body 1, which is the bottom support component of the mechanism. The lower fork body 1 is fixed to the stacker crane loading platform. A sliding groove 6 is provided on the upper inner wall of the lower fork body 1. The sliding groove 6 is used to realize the sliding connection of the connecting block 2. The sliding groove 6 is a trapezoidal groove, which can improve the stability during sliding and prevent the connecting block 2 from shifting. The connecting block 2 is slidably connected to the inner wall of the sliding groove 6, and the connecting block 2 is used to connect the lower fork. The middle fork body 3 is fixedly connected to the upper side of the connecting block 2. The middle fork body 3 is the middle telescopic component of the fork. The upper fork body 5 is slidably connected to the inner wall of the middle fork body 3. The upper fork body 5 is the top telescopic component of the fork and is used to carry goods. A stabilizing component is provided on the upper side of the upper fork body 5. The stabilizing component is used to improve the stability of the upper fork body 5 when carrying goods and prevent shaking. A slider 7 is elastically connected to the inner wall of the slide groove 6 through a spring 11. The spring 11 can provide elastic force to make the slider 7 move. Block 7 has a reset function. The slider 7 is trapezoidal in shape, and its trapezoidal structure matches the trapezoidal groove of the slide 6, ensuring smooth and stable sliding. The slider 7 is slidably connected to the inner wall of the slide 6. One end of the spring 11 is fixedly connected to the inner wall of the slide 6, and the other end of the spring 11 is fixedly connected to the front side of the slider 7. A connecting post 10 is fixedly connected to the front side of the slider 7, which connects the slider 7 and the slide plate 9. The connecting post 10 passes through and slidably connects to the rear inner wall of the tank body 8. A sliding plate 9 is fixedly connected to the front side of the connecting column 10. The sliding plate 9 can slide inside the tank 8 and cooperate with the connecting column 10 to transmit force. The outer wall of the sliding plate 9 is slidably connected to the inner wall of the tank 8. The diameter of the sliding plate 9 is larger than the diameter of the connecting column 10, which can prevent the connecting column 10 from detaching from the tank 8 and play a limiting role. A through hole 12 is provided on the inner wall of the sliding plate 9. The through hole 12 is designed to allow the buffer solution to flow. The tank 8 is fixedly connected to the inner wall of the lower fork 1. The tank 8 contains the buffer solution.

[0036] Reference Figure 3 and Figure 4 The stabilizing component includes an anti-slip strip 4, which increases the friction between the cargo and the upper fork 5 to prevent the cargo from sliding. The upper side of the anti-slip strip 4 is slightly higher than the upper side of the upper fork 5. This design allows for more effective contact with the cargo and enhances the anti-slip effect. A horizontal groove is provided on the upper side of the anti-slip strip 4, which further increases the friction and improves the anti-slip performance. The anti-slip strip 4 is snapped onto the inner right side wall of the upper fork 5. A limit block 13 is elastically connected to the inner upper side wall of the upper fork 5 by a spring 14. The spring 14 provides elastic force to the limit block 13 to achieve the limiting function. The upper right side of the limit block 13 is inclined. The outer wall of the limit block 13 is slidably connected to the inner upper side wall of the upper fork 5. One end of the spring 14 is fixedly connected to the inner upper side wall of the upper fork 5, and the other end of the spring 14 is fixedly connected to the lower side of the limit block 13.

[0037] Working principle: When the stacker crane forks extend or retract, the middle fork 3 slides within the groove 6 of the lower fork 1 via the connecting block 2, while the upper fork 5 extends or retracts synchronously within the middle fork 3 to adjust the working range. During this process, the trapezoidal groove structure of the groove 6 matches the trapezoidal slider 7, which restricts the sliding direction of the connecting block 2, preventing lateral deviation and providing basic guiding stability for the extension and retraction of the middle fork 3.

[0038] When connecting block 2 slides, it compresses slider 7 in slide groove 6. Slider 7 pushes slide plate 9 within tank 8 via connecting post 10. Since tank 8 contains buffer solution, the buffer solution needs to flow through through hole 12 on slide plate 9 when slide plate 9 moves, creating a damping effect. At the same time, spring 11 undergoes elastic deformation due to compression by slider 7, accumulating restoring force. The damping effect and the elastic force of spring 11 work together to buffer the impact when connecting block 2 slides, reduce the relative sway between middle fork body 3 and lower fork body 1, and achieve dynamic stability during fork extension and retraction.

[0039] When the forks are carrying cargo, the stabilizing components on the upper fork body 5 come into play: the upper side of the anti-slip strip 4 is slightly higher than the upper fork body 5 and has a transverse groove, allowing it to directly contact the cargo and preventing it from sliding by increasing the friction of the contact surface; at the same time, the limiting block 13, under the elastic force of the second spring 14, pushes the anti-slip strip 4 upward to ensure that the anti-slip strip 4 is stably engaged in the upper fork body 5 and prevents it from loosening. The combination of these two components enhances the connection stability between the cargo and the upper fork body 5, preventing the cargo from swaying and causing the entire fork to sway.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
