Description

Technical Field

[0001] The invention belongs to the technical field of transportation equipment, and in particular relates to a horizontal pallet lifting transporter used in a stereoscopic warehouse. Background Art

[0002] With the rapid development of modern times, warehousing and logistics are increasingly pursuing efficiency. Modern warehousing is no longer an isolated link, but a part of supply chain management. It is closely linked to procurement, production, distribution and other links, supporting the optimization and coordination of the supply chain. Modern warehousing mostly uses stereoscopic warehouses, also known as high-rise shelf warehouses or automated stereoscopic warehouses. It is a modern storage facility. Its main feature is the use of high-rise shelves and automated handling equipment to store and retrieve goods to maximize the use efficiency of warehouse space and improve the speed and accuracy of logistics operations. Stereoscopic warehouses mostly use horizontal pallet handling robots to transfer goods. Compared with transmission forklifts, horizontal pallet handling robots have many advantages.

[0003] Horizontal pallet handling robots can be designed to work in narrow spaces, reducing the required aisle width, thereby increasing storage density and space utilization; horizontal pallet handling robots can be dispatched by a central control system and dynamically adjust task priorities based on real-time demand, while traditional forklifts require manual coordination and scheduling; horizontal pallet handling robots can collect large amounts of work data to help companies conduct data analysis, optimize logistics processes, and improve the transparency and efficiency of the overall supply chain, etc.

[0004] Although pallet handling robots have many advantages in high-bay warehouses, the driven horizontal pallet handling robots can only work on the same shelf level. In high-bay warehouses, a separate lifting device is required to transport the horizontal pallet handling robots to shelves at different heights so that the horizontal pallet handling robots can perform three-dimensional work. This invisibly reduces the working efficiency of the horizontal pallet handling robots and increases the design difficulty of high-bay warehouses. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a horizontal pallet lifting and transporting vehicle for a three-dimensional warehouse. The present invention can enable a horizontal pallet transporting robot to lift and lower on a three-dimensional shelf. There is no need to set up a lifting device separately, so that the horizontal pallet transporting robot can work across layers, thereby effectively improving the work efficiency of the horizontal pallet transporting robot.

(2) In the present invention, when the vehicle body reaches the designated partition position, the loading mechanism is placed on the partition, the loading mechanism enters under the pallet, the hydraulic lifting rod lifts and drives the top plate to rise vertically to lift the pallet, and then brings the pallet back to the top of the vehicle body. Finally, the hydraulic lifting rod contracts and drives the top plate to drop vertically to place the pallet on the vehicle body to achieve loading of the goods. The hydraulic lifting rod lifts and drives the top plate to rise vertically to lift the pallet on the vehicle body, and then drives the pallet to move to the partition. The hydraulic lifting rod contracts and drives the top plate to drop vertically to put the pallet down, and the loading mechanism returns to the vehicle body to achieve unloading of the goods onto the partition. The vehicle body can conveniently load and unload goods on partitions of different heights, effectively improving the working efficiency of the horizontal pallet handling robot.

[0037] like Fig.11 - Fig.14As shown, the climbing mechanism 5 is composed of a plurality of climbing gears 51 and a transmission chain 52. The climbing gears 51 are rotatably connected to the front side of the climbing plate 4, and the climbing gears 51 are connected by the transmission chain 52. The front side of the vehicle body mechanism 1 is rotatably connected to a first driving wheel 11, and the rear side of the vehicle body mechanism 1 is rotatably connected to a steering wheel 12.

[0041] Working principle: When the vehicle body 1 is working in a horizontal plane, the first driving wheel 11 rotates to drive the vehicle body 1 to move forward or backward, and cooperates with the steering wheel 12 to allow the vehicle body 1 to travel to a designated location; When the goods need to be loaded, the loading mechanism 2 can move to the front side of the vehicle body mechanism 1, and the loading mechanism 2 can enter under the pallet. The hydraulic jacking rod 23 is lifted to drive the top plate 24 to rise vertically to lift the pallet, and then the pallet is brought back to the top of the vehicle body mechanism 1. Finally, the hydraulic jacking rod 23 is retracted to drive the top plate 24 to drop vertically to place the pallet on the vehicle body mechanism 1. When unloading the goods, the hydraulic jacking rod 23 is lifted to drive the top plate 24 to rise vertically to lift the pallet, and then the pallet is moved to the front side of the vehicle body mechanism 1. The hydraulic jacking rod 23 is retracted to drive the top plate 24 to drop vertically to put the pallet down, and the loading mechanism 2 returns to the vehicle body mechanism 1, and the unloading of the goods is completed. When the vehicle body mechanism 1 is required to perform three-dimensional operation, the vehicle body mechanism 1 moves in front of the three-dimensional shelf 6, and the climbing plate 4 enters the climbing guide rail 61.

The hydraulic jacking rod 23 lifts and drives the top plate 24 to vertically lift the pallet, and then brings the pallet back to the top of the vehicle body 1. Finally, the hydraulic jacking rod 23 contracts and drives the top plate 24 to vertically descend and place the pallet on the vehicle body 1, thereby realizing the loading of the goods. The hydraulic jacking rod 23 is lifted to drive the top plate 24 to rise vertically to lift the pallet on the vehicle body mechanism 1, and then drives the pallet to move to the partition 62. The hydraulic jacking rod 23 is retracted to drive the top plate 24 to drop vertically to put the pallet down, and the loading mechanism 2 returns to the vehicle body mechanism 1 to unload the goods onto the partition 62. When it is necessary to descend, the first driving wheel 11 reverses to drive the climbing gear 51 to reverse, and the climbing plate 4 descends in the climbing guide rail 61 and then drives the vehicle body 1 to descend on the three-dimensional shelf 6; The control motor 33 drives the two locking plates 31 to approach each other, and the roller 311 is retracted into the climbing plate 4 to release the lock of the climbing plate 4, so that the vehicle body mechanism 1 can drive away from the three-dimensional shelf 6.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
