Description

Technical Field

[0001] This utility model relates to the field of stacker crane technology, and more specifically, to a stacker crane anti-sway device. Background Technology

[0002] In modern logistics warehousing systems, automated storage and retrieval systems (AS / RS) have become the mainstream development direction of the warehousing industry due to their high space utilization and rapid cargo storage and retrieval capabilities. Stacker cranes, as the core equipment of AS / RS, undertake the tasks of vertical lifting and horizontal handling of goods. Stacker cranes are a type of warehousing equipment (see material handling machinery), and are divided into two types: bridge stacker cranes and aisle stacker cranes (also known as aisle cranes). Among them, aisle stacker cranes are widely used due to their high transportation efficiency and fast movement speed.

[0003] Existing stacker cranes operate at high speeds during actual use. They are used to transfer and stack goods by controlling the lifting platform to move up and down and driving the loading platform to move horizontally. The loading platform of existing stacker cranes has a flat plate structure on top, which makes the goods on the stacker crane prone to swaying and shaking during the movement of the stacker crane. In severe cases, this may cause the goods to fall off the stacker crane and be damaged. Therefore, an anti-sway device for stacker cranes is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a stacker crane anti-sway device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stacker crane anti-sway device, comprising a lifting platform and a loading platform that moves back and forth on the top of the lifting platform. The lifting platform is used to realize the vertical lifting of the loading platform, and the loading platform is responsible for carrying goods and moving them in the horizontal direction. The two constitute the basic platform for the stacker crane to handle goods. Limiting strips are symmetrically arranged on both sides of the loading platform at the top of the lifting platform. Limiting side plates are symmetrically arranged on opposite sides of the two limiting strips. A first electric push rod is symmetrically fixedly connected to opposite sides of the two limiting side plates. The output end of the first electric push rod is connected to a pressing plate. Activating the first electric push rod controls the movement of the pressing plate, which can clamp and limit the material that moves between the two limiting side plates.

[0006] A stabilizing rod is fixedly connected to one side of the extrusion plate, a buffer plate is provided on one side of the extrusion plate, and multiple springs are fixedly connected to one side of the buffer plate. The stabilizing rod improves the stability of the movement of the limiting side plate, and the buffer plate and springs work together to buffer the movement during clamping, thus avoiding rigid collisions that could damage the loading platform and the goods.

[0007] The loading platform has symmetrically arranged limit grooves at both ends of its top. A threaded rod is located in the middle of each limit groove, and a self-locking motor is installed at one end of the threaded rod. Moving plates are symmetrically arranged at both ends of the loading platform's top. Limit sliders are fixedly connected to the bottom of each moving plate, and a fixed box is fixedly connected to the top of each moving plate. A baffle is rotatably connected to the top of the fixed box, and an angle drive mechanism is located in the middle of the fixed box. By activating the self-locking motor to control the rotation of the threaded rod, the fixed box can be driven by the limit sliders to move the baffle. This multi-functional mechanism can limit the movement of materials on both sides, improving the stability of material movement and preventing swaying. Activating the angle drive mechanism can also control the rotation of the baffle, facilitating adjustment of its position.

[0008] Preferably, the upper and lower ends of the buffer plate are inclined, and the two ends of the spring are fixedly connected to the walls of the extrusion plate and the buffer plate, respectively. Through the cooperation of the buffer plate and the spring, the extrusion clamping can be buffered.

[0009] Preferably, the two buffer plates are arranged on opposite sides of the two extrusion plates, the stabilizing rod passes through the limiting side plate and is fixedly connected to the limiting plate, the limiting side plate and the limiting strip are both fixed on the lifting platform, and the material can be clamped and fixed by the extrusion plate driving the buffer plate to move.

[0010] Preferably, the limiting slider is adapted to the limiting slide groove, the limiting slider is disposed in the middle of the limiting slide groove, the threaded rod passes through the limiting slider and is threadedly connected to the limiting slider, and by rotating the threaded rod, the limiting slider can be controlled to drive the moving plate to move, so as to facilitate the adjustment of the position of the baffle.

[0011] Preferably, the angle driving mechanism includes a gear fixed to the end of a rotating shaft at one end of the baffle, the gear being disposed in the middle of the fixed box, and a rack being disposed on one side of the gear, the rack and the gear meshing together.

[0012] Preferably, limit blocks are symmetrically fixedly connected to both ends of one side of the rack, and a fixed block is fixedly connected to the side of the rack away from the fixed block. A second electric push rod is provided on one side of the fixed block. The second electric push rod is fixed to the top of the moving plate. Activating the second electric push rod controls the fixed block to drive the rack to move. Through cooperation with gears, the baffle can be rotated and the angle of the baffle can be adjusted. During the operation of the stacker crane, the angle of the baffle can be adjusted according to the horizontal movement direction of the loading platform to block and limit the goods, thereby suppressing the swaying of the goods.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model first controls the extrusion plate to drive the buffer plate to limit the material on both sides by starting the first electric push rod, which can improve the stability of two of the materials. Then, by starting the second electric push rod, the baffle is rotated in sequence, and the self-locking motor is started to control the baffle to extrude and limit the material on the other two sides, which can realize the limitation of the material on all four sides, improve the stability of the material on the top of the loading platform, improve the stability of the material during high-speed movement, avoid swaying, and improve the stacking and rotation effect.

[0015] 2. This utility model also uses a buffer plate and spring to buffer the load during clamping, avoiding damage to the loading platform and goods caused by rigid collisions. The stabilizing rod can improve the stability of the extrusion plate movement. By activating the second electric push rod, the fixed block can be controlled to drive the rack to move, which can control the gear to drive the baffle to rotate, making it easy to adjust the baffle angle. The moving distance of the rack is limited by the limiting block, which is convenient for driving adjustment and does not affect the normal movement of the loading platform.

[0016] In summary, through the interaction of the above-mentioned multiple functions, it is possible to limit the movement of materials around their perimeter, improve the stability of materials on the top of the loading platform, enhance the stability of materials during high-speed movement, prevent swaying, and improve the stacking and rotation effect.

[0024] As attached Figure 1-5 The stacker crane anti-sway device shown includes a lifting platform 1 and a loading platform 2 that moves back and forth on the top of the lifting platform 1. The lifting platform 1 is used to realize the vertical lifting of the loading platform 2, and the loading platform 2 is responsible for carrying goods and moving in the horizontal direction. The two constitute the basic platform for the stacker crane to handle goods. Limiting strips 3 are symmetrically arranged on both sides of the loading platform 2 at the top of the lifting platform 1.

[0025] A stabilizing rod 7 is fixedly connected to one side of the extrusion plate 6, a buffer plate 8 is provided on one side of the extrusion plate 6, and multiple springs 9 are fixedly connected to one side of the buffer plate 8. The stabilizing rod 7 improves the stability of the movement of the limiting side plate 4, and the buffer plate 8 and springs 9 work together to buffer the movement during clamping, thus avoiding rigid collisions that could damage the loading platform 2 and the goods.

[0026] The loading platform 2 has symmetrically arranged limit grooves 10 at both ends of the top. A threaded rod 11 is provided in the middle of the limit groove 10. A self-locking motor is provided at one end of the threaded rod 11. A movable plate 12 is symmetrically arranged at both ends of the top of the loading platform 2.

A baffle 16 is rotatably connected to the top of the fixed box 14. An angle drive mechanism is provided in the middle of the fixed box 14. By starting the self-locking motor to control the rotation of the threaded rod 11, the fixed box 14 can be driven by the limit slider 13 to drive the baffle 16. This multi-functional mechanism can limit the other two sides of the material, improve the stability of the material movement process, and play a role in preventing swaying movement. By starting the angle drive mechanism, the rotation of the baffle 16 can be controlled, making it easy to adjust the position of the baffle 16.

[0027] As attached Figure 1-5As shown, the upper and lower ends of the buffer plate 8 are inclined, and the two ends of the spring 9 are fixedly connected to the walls of the extrusion plate 6 and the buffer plate 8, respectively. The two buffer plates 8 are set on opposite sides of the two extrusion plates 6. The stabilizing rod 7 passes through the limiting side plate 4 and is fixedly connected to the limiting plate. The limiting side plate 4 and the limiting strip 3 are both fixed on the lifting platform 1. The limiting slider 13 is adapted to the limiting slide groove 10. The limiting slider 13 is set in the middle of the limiting slide groove 10. The threaded rod 11 passes through the limiting slider 13 and is threadedly connected to the limiting slider 13.

[0028] As attached Figure 1-5 As shown, the angle drive mechanism includes a gear 15 fixed to the end of a rotating shaft at one end of the baffle 16. The gear 15 is located in the middle of the fixed box 14. A rack 17 is provided on one side of the gear 15, and the rack 17 meshes with the gear 15.

A second electric push rod 20 is provided on one side of the fixed block 19. The second electric push rod 20 is fixed to the top of the moving plate 12. Activating the second electric push rod 20 controls the fixed block 19 to drive the rack 17 to move. Through cooperation with the gear 15, the baffle 16 can be rotated and its angle adjusted. During the operation of the stacker crane, the angle of the baffle 16 can be adjusted according to the horizontal movement direction of the loading platform 2 to block and limit the goods, thereby suppressing the swaying of the goods.

[0029] It is worth noting that the structure that drives the loading platform 2 to move on top of the lifting platform 1 is existing technology, which is often driven by the cooperation of chains and gears, and is used to move goods.

[0032] At this time, the first electric push rod 5 is activated to control the extrusion plate 6 to drive the buffer plate 8 to extrude and limit the material. At the same time, the second electric push rod 20 is activated to control the baffle 16 to rotate in sequence, so that the baffle 16 is located on the other two sides of the goods. Then, the self-locking motor is activated to control the baffle 16 to extrude and limit the material on both sides in sequence. This can achieve clamping and limiting of the material around its perimeter, improve the stability of the material movement, avoid swaying, and improve the use effect.
