Description

Technical Field

[0001] This utility model relates to the field of stacking equipment technology, and in particular to a side-impact resistant heavy-duty stacking equipment. Background Technology

[0002] Stacker cranes are core equipment in automated warehousing systems used for storing, retrieving, and handling goods. They enable precise positioning and retrieval of goods on high-rise racks, featuring high automation and high operating efficiency, and are widely used in logistics warehousing, manufacturing, and other fields. Heavy-duty stacker cranes, on the other hand, are stacking equipment designed for goods with large load-bearing capacity and special dimensions. They have higher structural strength and load-bearing capacity far exceeding that of ordinary stacker cranes, and can meet the stacking needs of heavy industrial materials such as steel and large mechanical parts. They play an important role in scenarios with stringent load-bearing requirements, such as metallurgy and heavy machinery manufacturing.

[0003] In modern intelligent warehousing operations, stacker cranes are the core of efficient goods storage, retrieval, and transportation; however, their operation poses significant safety hazards. In narrow aisle spaces, forklifts, AGVs, and other transport equipment are prone to side collisions with high-speed stacker cranes due to operational errors, blind spots, or improper path planning during overlapping operations. These collisions not only deform the stacker crane's outer shell but also damage precision components such as guide wheels and encoders, causing operational jams, positioning errors, and even system shutdowns. Furthermore, during rapid lifting and lateral movement of the stacker crane, if the pallet's anti-slip properties are poor or the goods are not securely fixed, goods can easily slide and tip over due to inertia. This not only damages goods but also can cause falling debris to block tracks, leading to secondary accidents and seriously threatening the safety and efficiency of warehousing operations. Therefore, a side-impact resistant heavy-duty stacker crane is proposed to address these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a side-impact resistant heavy-duty stacking equipment, which aims to improve the problem of the stacker crane being easily hit from the side and the goods falling off the loading platform during operation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a side-impact resistant heavy-duty stacking equipment, including a stacker crane, two cargo plates are provided on the outside of the stacker crane, an anti-collision component is provided on the outside of the stacker crane, and an anti-slip component is provided inside the cargo plates;

[0006] The anti-collision assembly includes two protective plates. Multiple fixing blocks are fixedly connected to the outer side of the protective plates. A damper is fixedly connected to the outer side of each fixing block. A spring is fixedly connected to the outer side of each fixing block. Multiple fixing blocks are fixedly connected to the outer side of the protective plates. A connecting rod is rotatably connected to the outer side of each fixing block. A support rod is rotatably connected to the outer side of the connecting rod. A spring is fixedly connected between two support rods on the same side. Multiple fixing seats are fixedly connected to the outer side of the stacker crane. A guide rod is fixedly connected between two fixing seats on the same side.

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

[0008] The anti-slip component includes a baffle, a gear fixedly connected to the bottom of the baffle, limit rods rotatably connected to both sides of the gear, a rotating rod fixedly connected inside the cargo plate, a cylinder fixedly connected inside the cargo plate, a fixed rod fixedly connected to the output end of the cylinder, and a rack fixedly connected to the outside of the fixed rod, the rack meshing with the gear.

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

[0010] The spring is set on the outside of the damper, and the end of the spring away from the fixed block is fixedly connected to the outside of the stacker crane.

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

[0012] The spring is sleeved on the outside of the guide rod.

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

[0014] The support rod is slidably connected to the outside of the guide rod.

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

[0016] The gear is rotatably connected to the outside of the rotating rod, and the limiting rod is fixedly connected to the outside of the rotating rod.

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

[0020] The fixing rod is slidably connected inside the cargo plate, and the rack is slidably connected inside the cargo plate.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when an impact occurs, the protective plate is the first to come into contact with the impacting object, generating a tendency to displace towards the stacker crane. This displacement causes the fixed block one to slide, while simultaneously compressing the spring one, converting the impact kinetic energy into elastic potential energy for initial buffering. The damper, through an energy dissipation mechanism, converts the vibration energy into heat energy, weakening the vibration. At the same time, the protective plate drives the fixed block two, which, through the connecting rod and support rod, transmits the impact force to the spring two. The guide rod constrains the directional movement of the support rod, and the spring two disperses the impact force through compression and stretching, realizing the gradual conversion of impact energy and the dispersion and buffering of impact force, effectively protecting the main body of the stacker crane and its internal precision components, and ensuring the continuity of warehousing operations.

[0023] 2. In this utility model, when the cargo anti-slip mechanism is activated, the cylinder outputs driving force to push the fixed rod to slide, causing the rack to move linearly on the cargo plate slide rail. The rack meshes with the gear, converting the linear motion into rotational motion. The gear drives the coaxial baffle to rotate around the rotating rod. The gear's non-full-tooth structure precisely controls the baffle's rotation angle, making it stably upright. The upright baffle forms a physical barrier, achieving precise rotation and uprighting of the baffle, forming a physical protective barrier, effectively preventing cargo from sliding and tipping over during transportation, and ensuring the safe operation of warehousing and logistics equipment.

[0030] 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.

[0031] Reference Figures 1-4 This utility model provides an embodiment of a side-impact resistant heavy-duty stacking equipment, including a stacker crane 1. Two cargo pallets 2 are arranged on the outside of the stacker crane 1. Anti-collision components are arranged on the outside of the stacker crane 1, and anti-slip components are arranged inside the cargo pallets 2. The stacker crane 1 is used to store, retrieve, and transport goods in an automated warehousing system. The two cargo pallets 2 form a loading platform, which is a platform for the stacker crane 1 to carry goods. The anti-collision components reduce the risk of the stacker crane 1 being hit from the side by buffering the impact force, and the anti-slip components are used to prevent goods from falling off the cargo pallets 2.

[0032] The anti-collision assembly includes two protective plates 3. Multiple fixing blocks 4 are fixedly connected to the outer side of the protective plates 3. A damper 5 is fixedly connected to the outer side of fixing block 4. A spring 6 is fixedly connected to the outer side of fixing block 4. Multiple fixing blocks 7 are fixedly connected to the outer side of fixing block 7. A connecting rod 8 is rotatably connected to the outer side of the connecting rod 8. A support rod 9 is rotatably connected to the outer side of the connecting rod 8. A spring 11 is fixedly connected between two support rods 9 on the same side. Multiple fixing seats 19 are fixedly connected to the outer side of the stacker crane 1. A guide rod 10 is fixedly connected between two fixing seats 19 on the same side. The protective plate 3, as the first contact component in a collision, directly bears the external impact force and transmits the force to the subsequent buffer structure. Simultaneously, it can disperse and resist impact to a certain extent, protecting the main body of the stacker crane 1. The fixing blocks 4 serve as a connection, providing mounting points for the springs 6 and dampers 5. Upon impact, the damping material or structural characteristics of the damper 5 are utilized. The impact vibration is attenuated, reducing the impact force on the main body of the stacker crane 1 and achieving buffering and vibration reduction. Spring 6 absorbs impact energy by means of the elastic deformation of the spring. It compresses and deforms to store energy during impact and then slowly releases it to buffer the instantaneous impact force and protect the equipment structure. It mainly plays a buffering role when the protective plate 3 is impacted. Fixed block 7 plays a connecting and limiting role, restricting the range of motion of the connecting rod 8 to ensure orderly force transmission. The connecting rod 8 transmits the impact force and transmits the force borne by the protective plate 3 to the support rod 9 and the spring 11 buffer component, so that the force is transmitted in an orderly manner between the various structures and works together to play a buffering role. The support rod 9 plays a supporting and auxiliary force transmission role. The fixed seat 19 is used to stably fix the guide rod 10 on the outside of the stacker crane 1. The guide rod 10 provides guidance for the spring 11, ensuring that the spring 11 and the support rod 9 deform and reset in a preset direction during impact, maintaining the stability of the buffer structure and ensuring the buffering effect.

[0033] The anti-slip component includes a baffle 12, with a gear 15 fixedly connected to the bottom of the baffle 12. Limiting rods 14 are rotatably connected to both sides of the gear 15. A rotating rod 13 is fixedly connected inside the cargo plate 2, and a cylinder 18 is fixedly connected inside the cargo plate 2. A fixing rod 17 is fixedly connected to the output end of the cylinder 18, and a rack 16 is fixedly connected to the outside of the fixing rod 17. The rack 16 meshes with the gear 15. The baffle 12 is the component that directly acts on the cargo. By flipping itself, it prevents the cargo from sliding or tipping over, physically restricting the cargo's position and preventing it from falling off. It is the actuator of the anti-slip component. The gear 15, by meshing with the rack 16, converts the linear motion of the rack 16 into its own rotational motion, thereby driving the baffle. 12 flips over. Limiting rod 14 is used to limit the movement range of gear 15 to prevent excessive rotation or positional deviation. Rotating rod 13 provides rotational support for baffle 12 and is the shaft for baffle 12 to achieve flipping action. Cylinder 18 serves as a power source, outputting linear thrust or pull force to drive rack 16 to perform linear motion, providing power for the entire anti-fall mechanism. The start and stop of the action and speed adjustment are realized through pneumatic control. Fixing rod 17 plays a fixing and supporting role, providing an installation reference for the transmission components of gear 15 and rack 16, ensuring the relative stability of the positions of each component, and ensuring the meshing accuracy and reliability of gear 15 and rack 16. Rack 16 has a partial tooth segment structure, used to limit the rotation range of gear 15.

[0034] Spring 6 is fitted on the outside of damper 5. The end of spring 6 away from fixed block 4 is fixedly connected to the outside of stacker 1. When there is an impact, spring 6 first elastically deforms to buffer, and damper 5 synchronously dampens the vibration. Spring 6 is fixedly connected to stacker 1, which can stabilize the force transmission path.

[0035] Spring 2 11 is sleeved on the outside of guide rod 10. When stacker crane 1 is running or is impacted, spring 2 11 deforms along guide rod 10 to absorb horizontal impact force. Guide rod 10 provides guidance to prevent spring 2 11 from deviating, ensure buffer stability, and avoid damage to the bottom structure due to impact.

[0036] The support rod 9 is slidably connected to the outside of the guide rod 10. The support rod 9 is used to maintain the stability of the stacker crane 1; at the same time, it participates in the force distribution and transmission to avoid local stress concentration.

[0037] Gear 15 is rotatably connected to the outside of rotating rod 13, and limiting rod 14 is fixedly connected to the outside of rotating rod 13. Spring 11 drives gear 15 to rotate around rotating rod 13, thereby causing baffle 12 to flip. Limiting rod 14 is fixed on rotating rod 13 to limit the rotation range of gear 15 and baffle 12, ensuring that baffle 12 moves within the preset angle of blocking goods and preventing excessive rotation failure.

[0038] The baffle 12 is rotatably connected inside the cargo platform 2. With the help of the rotatable connection, the baffle 12 can rotate around the rack 16. When the goods are being transported, it can be laid flat without interference, and when it is necessary to prevent it from falling, it can be erected to block the way. The rotatable connection allows the baffle 12 to flexibly switch its posture to adapt to different needs of handling and protection in warehousing operations.

[0039] The fixed rod 17 is slidably connected inside the cargo plate 2, and the rack 16 is slidably connected inside the cargo plate 2. The rack 16 is driven by the cylinder 18 and slides linearly along the inner track of the cargo plate 2.

[0040] Working principle:

[0041] When an impact occurs, the protective plate 3 first contacts the impacting object and tends to displace towards the stacker crane 1. This displacement drives the damper 5 to slide through the fixed block 4, while simultaneously compressing the spring 6, converting some of the impact kinetic energy into elastic potential energy, thus achieving initial buffering. The damper 5 then converts the vibration energy into heat energy through an energy dissipation mechanism, effectively attenuating the vibration amplitude. At the same time, the protective plate 3 drives the fixed block 7 to move synchronously. Through the linkage mechanism of the connecting rod 8 and the support rod 9, the impact force is transmitted to the spring 11 in an orderly manner. The guide rod 10 provides directional motion constraint for the support rod 9. When the equipment shakes due to the impact, the support rod 9 slides along the guide rod 10, and the spring 11 disperses and buffers the impact force at the bottom and sides through compression or stretching. Through the synergistic effect of the multi-stage buffering system, the composite vibration reduction structure composed of the spring and the damper 5 significantly weakens the impact force, effectively protecting the main structure and internal precision components of the stacker crane 1, ensuring stable operation of the equipment and continuity of warehousing operations.

[0042] When the cargo anti-slip mechanism is triggered, cylinder 18, as a power source, outputs driving force to push fixed rod 17 to slide along a predetermined track, which in turn drives rack 16 to move linearly on the internal slide rail of cargo plate 2. The gear tooth structure of rack 16 meshes with gear 15 to form a transmission. Through mechanical transmission conversion, the linear motion is converted into the rotational motion of gear 15. Gear 15 is coaxially connected to baffle 12. Its rotation drives baffle 12 to rotate around rotating rod 13 inside cargo plate 2 to achieve a flipping action. In terms of design, gear 15 adopts a non-full gear tooth structure to precisely control the rotation angle of baffle 12 and ensure that it can stand stably. After standing, baffle 12 effectively restricts the tendency of cargo to slide and tip over during transportation by physically blocking it, forming a reliable protective barrier, thereby realizing the function of preventing cargo from falling off and ensuring transportation safety, and providing mechanical guarantee for the stable operation of warehousing and logistics equipment.
