[0030] Please see Figure 1-6 This utility model provides a push-pull device for the dragging and pushing of a stacker crane, including a loading platform 13. A traction device 2 is slidably connected to the top side of the loading platform 13. A drive device 5 and an encoder 6 are installed at one end of the loading platform 13. The drive device 5 includes a drive motor, a sprocket, and a chain. The drive device 5 pulls the traction device 2 to move on the top of the loading platform 13 through the sprocket and chain structure. A pallet 1 is engaged with one end of the traction device 2. In use, by engaging the pallet 1 with one end of the traction device 2, the drive device 5 pulls the traction device 2 to move on the top of the loading platform 13, thereby moving the pallet 1 and achieving longitudinal placement of the pallet, effectively improving space utilization. The pallet 1 slides on the roller 4. The chain drive and the rolling structure of the channel steel wheel 10 within the channel steel 14 ensure the smooth movement of the traction device 2, thus ensuring... The smooth pulling of pallet 1 makes this device suitable for traction of longitudinally long goods, as well as other traction applications. When longitudinal length is required, it can be used for heavy-duty push-pull or light-duty synchronous belt drive applications, offering a wide range of applications and strong practicality. When high precision is required, the guide of the channel steel wheel 10 and channel steel 14 can be changed to a linear guide rail slider, making inbound and outbound processing more flexible. It effectively handles large and long workpieces, maximizing space utilization, and enabling efficient collaborative and networked operation. It boasts high scalability and flexibility, and different equipment combinations can achieve various intelligent applications such as whole-goods and small-quantity picking, temporary storage, and rapid replenishment. This invention is suitable for intelligent warehouses with long longitudinal pallet distances where conventional forks are unsuitable for picking and placing goods. It is primarily used in storage systems for large and long workpieces. It is adaptable to the integration of conveyor systems, WMS, and WCS systems to achieve intelligent management of dense storage. It can be used as peripheral equipment in automated warehouses or as an independent system. It can achieve linear push-pull picking and placing modes.

[0031] Further as Figure 1 , Figure 5 and Figure 6As shown, it is worth noting that the traction device 2 includes a traction frame 11. The bottom end of the traction frame 11 is rotatably connected to two shafts symmetrically distributed at both ends of the traction frame 11. Channel steel wheels 10 are fixed at both ends of the shafts. Two symmetrically distributed channel steels 14 are fixed at the top of the loading platform 13. The channel steels 14 are arranged along the length of the loading platform 13 and slide in cooperation with the channel steel wheels 10. In actual operation, in order to achieve flexible loading and unloading and simple and reliable structure, the traction device 2 is driven by a reducer to drive the sprocket. Its chain and chain adjusting screw are connected to the traction device. The channel steel wheels 10 are installed on the traction device 2 to ensure the smooth operation of the traction device 2. The traction device 2 is guided by the cooperation of the channel steel wheels 10 and the channel steels 14, instead of using a linear slide rail slider guide, which reduces cost and installation difficulty.

[0032] Further as Figure 4 As shown, it is worth noting that the top of the loading platform 13 is connected to a roller 4 that provides rolling support to the bottom surface of the pallet 1. There are multiple rollers 4, and they are evenly distributed. In order to address the problem of excessive longitudinal distance of the pallet 1 and heavy cargo, rollers 4 are installed at intervals on the loading platform 13 to support the pallet 1, so that the pallet 1 moves by rolling friction, which effectively reduces the frictional resistance of the pallet 1 and improves the smoothness of the pallet 1's movement.

[0033] Further as Figure 4 As shown, it is worth noting that the top of the loading platform 13 is rotatably connected with a guide roller 3 for guiding the pallet 1. There are multiple guide rollers 3 arranged in two rows, and the two rows of guide rollers 3 are symmetrically distributed on both sides of the traction device 2. In order to ensure that the pallet 1 is accurately guided into the middle position of the loading platform 13 due to the large longitudinal distance, the top of the loading platform 13 is equipped with guide rollers 3 to accurately guide the pallet 1 onto the loading platform 13.

[0034] Further as Figure 1 , Figure 5 and Figure 6 As shown, it is worth noting that an end support plate 12 is fixed to one end of the traction frame 11. There are two end support plates 12, and the two end support plates 12 are symmetrically distributed. A traction shaft 8 is fixed to both end support plates 12. A hook that engages with the traction shaft 8 is fixed to the front end of the pallet 1. There are two hooks, and the two hooks are symmetrically distributed. In order to realize the picking and placing of the pallet 1, the front end of the pallet 1 is equipped with double hooks, and the traction device 2 is equipped with a shaft. When picking up or placing goods, the shaft on the traction device 2 is hooked into the hook of the pallet 1, so that the pallet 1 rolls and rubs on the roller 4, making picking and placing flexible.

[0035] Further as Figure 1 As shown, it is worth noting that a detection plate 7 is fixed on the outer side wall of the traction frame 11.

[0036] Further as Figure 4 As shown, it is worth noting that bearings are installed at both ends of the idler roller 4, and the two ends of the idler roller 4 are rotatably connected to the side wall of the loading platform 13 through the bearings.

[0037] Further as Figure 2 As shown, it is worth noting that a thin rubber sleeve is fitted onto the surface of the traction shaft 8; during operation, the thin rubber sleeve effectively increases the engagement friction between the traction shaft 8 and the hook on the tray 1, thereby improving the stability of the engagement.

[0038] Further as Figure 2 and Figure 3 As shown, it is worth noting that the traction shaft 8 has two grooves 15 on its side, and the two grooves 15 are symmetrically distributed. In actual operation, the hook on the tray 1 is inserted into the groove 15, thereby limiting the hook through the groove 15, effectively improving the connection stability between the hook and the traction shaft 8, and reducing the left and right sway of the tray 1 when it is pulled and moved, thus improving the stability of the movement of the tray 1.

[0039] Further as Figure 2 and Figure 3 As shown, it is worth noting that rubber rings 16 are fixed on both sides of the groove 15, and the cross-section of the rubber rings 16 is elliptical. In actual operation, the rubber rings 16 elastically compress the hooks on the tray 1, thereby further improving the stability of the hooks and the traction shaft 8.

[0040] In summary: The traction device 2 is moved on the top of the loading platform 13 by the drive device 5, thereby moving the pallet 1 and achieving longitudinal placement of the pallet, effectively improving space utilization. The pallet 1 slides on the rollers 4. To accommodate large longitudinal distances of the pallet 1 and heavy loads, rollers 4 are installed at intervals on the loading platform 13 for support, making the pallet 1 move by rolling friction, effectively reducing the frictional resistance of the pallet 1 and improving the smoothness of its movement. The chain drive and the rolling structure of the channel steel wheel 10 within the channel steel 14 ensure the smooth movement of the traction device 2, thus ensuring the smooth pulling of the pallet 1. This device is suitable for traction of longitudinally long loads and can also be used in other traction applications. When the longitudinal length of the load is required, it can be used for heavy-duty push-pull or light-duty simultaneous loading. In applications involving belt drives, the application range is wide and the practicality is strong. When the precision requirements are too high, the guide of the channel steel wheel 10 and the channel steel 14 can be changed to the guide traction of the linear guide rail slider, making the inbound and outbound processing capacity more flexible. It can handle large and long workpieces with flexible handling and make full use of space. The thin rubber sleeve effectively increases the engagement friction between the traction shaft 8 and the hook on the tray 1, improving the engagement stability. The hook on the tray 1 is engaged in the groove 15, thereby limiting the hook through the groove 15, effectively improving the engagement stability between the hook and the traction shaft 8, and reducing the left and right sway of the tray 1 when it is pulled and moved, improving the movement stability of the tray 1. The rubber ring 16 provides elastic compression to the hook on the tray 1, thereby further improving the engagement stability between the hook and the traction shaft 8.
