Description

Technical Field

[0001] This utility model relates to the field of warehouse automation equipment technology, and in particular to a stacker crane anti-collision block for use in the aisles of an automated warehouse. Background Technology

[0002] Automated storage and retrieval systems (AS / RS) are an important component of modern logistics warehousing systems. They achieve high-density storage and automated retrieval of goods through high-rise racks and automated aisle stacker cranes. The stacker cranes operate at high speeds in narrow aisles, responsible for accurately storing goods in designated locations on the high-rise racks or retrieving them from those locations.

[0003] During the operation of a stacker crane, due to control system failure, positioning deviation, or sudden abnormalities, the stacker crane body or its loading platform may exceed the normal operating range and collide at high speed with the warehouse rack at the end or bottom of the aisle. This collision force is enormous and can easily cause deformation or even damage to the warehouse rack structure, affecting the operational safety of the entire warehouse, and may also damage the stacker crane itself.

[0004] To mitigate such collisions, some warehouses in the present technology simply install some protective structures at the ends of the racks, such as solid rubber blocks or metal blocks. However, these simple protective structures are very rigid or have a short buffer stroke. They mainly rely on the hardness of the material itself to resist impact and lack an effective energy absorption and dissipation mechanism. When a stacker crane experiences a severe collision, most of the impact force is still directly transmitted to the main body of the rack, which cannot play a sufficient protective role and results in poor protection.

[0005] Therefore, this utility model proposes a stacker crane anti-collision block for use in automated warehouse aisles to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of rigid protective structure and lack of effective energy absorption and mitigation mechanism in the existing stacker crane anti-collision blocks, which result in poor buffering and energy absorption effect and insufficient protection of the warehouse rack, this utility model aims to provide a stacker crane anti-collision block with improved structure that can effectively solve the above problems for use in the aisles of automated warehouses.

[0007] This utility model provides a stacker crane anti-collision block for use in automated warehouse aisles, including a warehouse frame and a baffle plate sleeved at the bottom of the warehouse frame. The anti-collision block also includes an installation component disposed on the baffle plate and an energy-absorbing component disposed inside the baffle plate. The baffle plate has a slot for moving part of the energy-absorbing component. The energy-absorbing component includes an energy-absorbing plate, a push block and a spring. The push block is fixedly connected to one side of the energy-absorbing plate and is slidably disposed in the slot. The spring is disposed between the energy-absorbing plate and the baffle plate. The energy-absorbing plate is in contact with the warehouse frame under the elastic force of the spring. The installation component includes a locking block, a locking bolt and a nut. The locking block is locked inside the baffle plate. The locking bolt passes through the locking block and the warehouse frame in sequence. The nut is screwed onto the end of the locking bolt away from the locking block. In addition, the baffle plate also has several honeycomb holes.

[0008] Preferably, the honeycomb holes are through holes that penetrate the wall of the baffle plate. This through structure helps to deform more fully when subjected to impact in order to absorb energy.

[0009] Preferably, the energy-absorbing panel has a contact surface facing the rack, and this contact surface is flat. This flat design increases the contact area with the rack, making the fit tighter and more stable.

[0010] Preferably, the pusher protrudes from the side of the energy-absorbing plate. This protruding structure is used to engage with the slot on the baffle to achieve stable sliding guidance.

[0011] Preferably, the number of springs is several, and these springs are evenly arranged between the energy-absorbing plate and the baffle to ensure that the energy-absorbing plate is subjected to uniform force.

[0012] Preferably, the number of honeycomb holes is several, and these several honeycomb holes are arranged in an array along the length of the baffle to optimize the overall strength and energy absorption effect of the baffle.

[0013] Preferably, the baffle has an end away from the mounting components, which is attached to the rack, so that both ends of the baffle can be attached to the rack after installation, thus improving the installation stability of the overall structure.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model solves the problems of existing warehouse racks lacking effective protection and being easily damaged by stacker crane impacts by opening honeycomb holes on the baffle and setting an energy-absorbing component consisting of an energy-absorbing plate and a spring inside the baffle. It also solves the problems of poor buffering and energy absorption effect of traditional protective devices, achieving the technical effect of dual energy absorption and synergistic dissipation of collision force, thus improving the protection capability of the warehouse rack.

[0016] 2. This utility model solves the problems of inconvenient installation of traditional protective devices, gaps between the push block and the baffle slot, and easy displacement or warping during collision by using a spring to keep the energy-absorbing plate in contact with the silo frame after installation. It also achieves the technical effects of convenient installation, stable structure and tight fit, ensuring that the anti-collision baffle can stably play a buffering role when subjected to impact.

[0024] 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.

[0025] Please refer to Figures 1 to 5 This utility model provides a stacker crane anti-collision block for aisles in automated warehouses, which aims to solve the problems in the prior art where the warehouse frame 1 lacks a dedicated anti-collision structure, making it susceptible to damage from stacker crane collisions, and the poor buffering and energy absorption effect of existing protective devices.

[0026] like Figure 1 As shown, a stacker crane anti-collision block for an automated warehouse aisle is installed on a rack 1, which is a shelf in the automated warehouse aisle. The anti-collision block includes a baffle 2, which is fitted onto the bottom of the rack 1. The anti-collision block also includes an installation component 5 installed on the baffle 2 and an energy-absorbing component 3 installed inside the baffle 2.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the baffle 2 has a slot for moving part of the energy absorption component 3. The baffle 2 also has several honeycomb holes 4, which are through holes that penetrate the wall of the baffle 2. The baffle 2 has another end away from the mounting component 5, which is attached to the frame 1.

[0028] Reference Figure 3 , Figure 4 and Figure 5 The energy-absorbing component 3 includes an energy-absorbing plate 301, a pusher block 302, and a spring 303. The pusher block 302 is fixedly connected to one side of the energy-absorbing plate 301. The pusher block 302 is slidably disposed in the slot and protrudes from the side of the energy-absorbing plate 301. The spring 303 is disposed between the energy-absorbing plate 301 and the baffle 2. There are several springs 303. The energy-absorbing plate 301 adheres to the bin frame 1 under the elastic force of the spring 303. The energy-absorbing plate 301 has a contact surface facing the bin frame 1, and the contact surface is a plane.

[0029] Reference Figure 1 The mounting component 5 is used to lock the baffle 2 to the bin frame 1. The mounting component 5 includes a locking block 502, a locking bolt 501, and a nut 503. The locking block 502 is locked inside the baffle 2. The locking bolt 501 passes through the locking block 502 and the bin frame 1 in sequence. The nut 503 is screwed onto the end of the locking bolt 501 away from the locking block 502.

[0030] The energy-absorbing assembly 3 includes an energy-absorbing plate 301, a pusher block 302, and a spring 303. The pusher block 302 is fixedly connected to one side surface of the energy-absorbing plate 301, and the structure of the pusher block 302 protrudes from the side surface of the energy-absorbing plate 301. The energy-absorbing plate 301 has a contact surface facing the shelf 1. The contact surface is flat to ensure stable contact with the surface of the shelf 1. There are several springs 303. One end of these springs 303 abuts against the inner side surface of the energy-absorbing plate 301, and the other end abuts against the inner wall of the baffle 2.

[0031] Meanwhile, a corresponding slot is provided on the baffle 2 for the movement of part of the energy absorption component 3. In the assembled state, the push block 302 slides in the slot. This sliding fit structure provides precise guidance and limit for the reciprocating movement of the energy absorption plate 301 in the baffle 2 along the length direction parallel to the bin frame 1. When subjected to external impact, the energy absorption plate 301 will move inward to compress the spring 303, converting the impact kinetic energy into the elastic potential energy of the spring 303.

[0032] In addition, as another energy-absorbing structure, the baffle 2 is also provided with several honeycomb holes 4. These honeycomb holes 4 are through holes that penetrate the wall of the baffle 2. When the baffle 2 is subjected to a huge impact force, the structure of the honeycomb holes 4 will deform, and absorb and dissipate a large amount of collision energy through the buckling deformation of the material. This combination of dynamic spring 303 buffer energy absorption and static structural deformation energy absorption ensures that the impact force can be effectively resolved under collisions of different intensities, thereby improving the protection capability of the warehouse frame 1.

[0033] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0034] As a preferred embodiment, to improve the energy absorption efficiency of the structure, the honeycomb holes 4 are through holes penetrating the wall of the baffle 2. This through-type structure makes the hole walls more prone to buckling deformation when subjected to impact, thereby dissipating more energy.

[0035] In a preferred embodiment, to optimize the overall strength and energy absorption ratio of the baffle 2, the number of honeycomb holes 4 is several, and these several honeycomb holes 4 are arranged in an array along the length direction of the baffle 2.

[0036] In a preferred embodiment, to ensure uniform force distribution on the energy-absorbing plate 301, a plurality of springs 303 are used, which are evenly distributed between the energy-absorbing plate 301 and the baffle 2.

[0037] In a preferred embodiment, to ensure stable contact with the rack 1, the energy-absorbing plate 301 has a contact surface facing the rack 1. This contact surface is flat. This flat design increases the contact area with the rack 1, resulting in a tighter fit under the action of the spring 303 and a more uniform transmission of impact force during collision.

[0038] In a preferred embodiment, to facilitate the sliding guide of the slot, the push block 302 protrudes from the side of the energy-absorbing plate 301. This protruding structure is adapted to and embedded in the slot on the baffle 2, allowing the push block 302 to slide stably within the slot, thereby driving the energy-absorbing plate 301 to move smoothly.

[0039] In a preferred embodiment, to improve the stability of the installation, the baffle 2 has an end away from the mounting component 5, which is also in close contact with the bin frame 1. This means that when the baffle 2 is fitted onto the bottom of the bin frame 1, both ends of the baffle 2 are in contact with the bin frame 1. Together with the mounting component 5 in the middle, a stable support structure is formed to prevent the baffle 2 from warping or shifting during a collision.

[0040] Working principle: When installing the anti-collision block, first pull the push block 302 of the energy-absorbing component 3. Since the push block 302 is slidably set in the slot of the baffle 2, this pulling action will drive the energy-absorbing plate 301, which is fixedly connected to the push block 302, to move synchronously, thereby compressing the spring 303 set between the energy-absorbing plate 301 and the baffle 2, providing installation space for the baffle 2 to be fitted onto the bottom of the bin frame 1. After fitting the baffle 2 onto the bottom of the bin frame 1 and making sure that the other end away from the installation component 5 is in contact with the bin frame 1, release the push block 302. 2. Once the tension is released, the spring 303 begins to reset. The elastic force of the spring 303 pushes the energy-absorbing plate 301 to move in the opposite direction until the contact surface of the energy-absorbing plate 301 facing the bin frame 1 is tightly attached to the bin frame 1. Then, the installation component 5 is used for final locking, the locking block 502 is locked in the baffle 2, and the locking bolt 501 is passed through the locking block 502 and the bin frame 1 in sequence. Finally, the nut 503 is screwed onto the end of the locking bolt 501 away from the locking block 502. At this time, the entire anti-collision block is firmly installed on the bin frame 1.

[0041] When a stacker crane in the aisle accidentally hits the anti-collision block, the impact force first acts on the baffle 2. At this time, the anti-collision block dissipates the collision energy through two synergistic mechanisms. On the one hand, the honeycomb holes 4 on the baffle 2 undergo structural deformation or buckling under the impact force, absorbing and dissipating a portion of the collision energy through material deformation. On the other hand, the remaining impact force is transferred to the energy-absorbing component 3, forcing the energy-absorbing plate 301 to overcome the preload of the spring 303 and move inward. The push block 302 slides synchronously in the slot. The movement of the energy-absorbing plate 301 compresses the spring 303, efficiently converting the kinetic energy of the collision into the elastic potential energy of the spring 303, thus achieving buffering and energy absorption. Through the dual action of the structural energy absorption of the honeycomb holes 4 and the buffering and energy absorption of the spring 303 in the energy-absorbing component 3, the collision force of the stacker crane is effectively dissipated, reducing the final impact force transmitted to the warehouse rack 1, thereby solving the problem of the warehouse rack 1 being easily damaged by collision in the prior art.
