Description

Technical Field

[0001] The present invention relates to the technical field of logistics transportation, and more specifically, to a walking type hydraulic combination platform. Background Art

[0002] Logistics refers to the whole process of planning, implementing and managing the transportation, storage and distribution of raw materials, semi-finished products, finished products or related information from the place of production to the place of consumption of goods in order to meet the needs of customers at the lowest cost and with high efficiency. Modern logistics is a product of economic globalization and an important service industry that promotes economic globalization. In the logistics process, sometimes it is necessary to move goods in a warehouse to another area.

[0003] In order to facilitate the loading and unloading of goods by large transport vehicles, existing large logistics warehouses have steps on the edge of the warehouse. There is a height difference between the steps and the ground, which is the distance between the logistics vehicle compartment and the ground. Due to the existence of the steps, when transferring goods between local warehouses, two steps need to be performed: going down the steps and going up the steps, which greatly reduces the efficiency of goods transfer. If logistics vehicles are used for transfer, due to the short distance between warehouses, not only is there little space for logistics vehicles to operate, but the efficiency of goods transfer is also reduced. Summary of the invention

[0004] In view of the above problems, the present invention provides a walking hydraulic combination platform, which has a first fixed frame and a second fixed frame respectively installed in the areas where two warehouses are located. The first fixed frame and the second fixed frame cooperate with steps. A transport connection part composed of a number of transport platforms that can be lifted up and down in the vertical direction is used to be spliced ​​with the first fixed frame and the second fixed frame to form a cargo transportation line to facilitate the transfer of cargo between warehouses.

[0005] The technical solution adopted by the present invention is: to provide a walking hydraulic combination platform, including a first fixed frame and a second fixed frame arranged relatively to each other and a transportation connection part, there is a spacing between the first fixed frame and the second fixed frame, the transportation connection part is composed of a plurality of transportation platforms that can be lifted up and down, the two ends of the transportation connection part are free ends, and the two free ends of the transportation connection part after rising are respectively spliced ​​with the first fixed frame and the second fixed frame to form a cargo transportation line.

The distance between the first fixed frame 1 and the second fixed frame 2 is the road for vehicles to travel. The two ends of the transport track 9 laid on the road surface extend to the directions of the first fixed frame 1 and the second fixed frame 2 respectively. The first transport platform 3 with a lowered height is accommodated in the bottom space of the first fixed frame 1, and the second transport platform 4 with a lowered height is accommodated in the bottom space of the second fixed frame 2. When goods need to be transferred between the two warehouses, the controller controls the two motors 64 to work, and the two moving mechanisms 6 respectively drive the first transport platform 3 and the second transport platform 4 to move toward each other.
