Description

Technical Field

[0001] The invention relates to the field of machinery, in particular to a storage and handling device, in particular to a stacking and lifting device for handling round steel pipes. Background Art

[0002] The storage and handling device for round steel pipes is mostly in the form of non-automatic flat storage, or in the form of stackers in combination with three-dimensional high-position storage. The storage process of round steel pipes in the prior art is as follows: a conventional flat fork stacker transports an empty pallet from the warehouse to the storage entry and exit position, and then sends it to the unloading position via the front-of-warehouse conveying system (double-chain conveyor line or RGV, AGV device). After the whole bundle of steel pipes is manually hoisted and placed on the pallet using the workshop crane, the belts are manually untied and the blank steel pipes are flattened. The fully loaded pallet is sent to the storage entry and exit position via the front-of-warehouse conveying system, and then sent to the designated cargo position in the warehouse by the stacker to complete the storage work. The prior art solution has the following defects: for one storage, the stacker needs to perform two displacement tasks (sending the empty pallet out of the warehouse and connecting the fully loaded pallet into the warehouse), and an additional pallet needs to be used as a carrier. The pallet occupies a large space. Combined with the tasks of material out of the warehouse and the empty pallet back to the warehouse in the later stage, the comprehensive storage area stacker's composite storage entry and exit capacity is about 15 pallets / hour, and the handling efficiency is low.

No pallets are required for storage in the warehouse, and the size of the cargo grid is designed based on the maximum diameter of the steel pipe. Take a 7-meter clear space workshop as an example: if the stacker in the prior art must use pallets to load steel pipes, 6 layers of storage cargo grids can be designed. The stacking lifting device of the present invention directly forks a whole row of steel pipes, and 9 layers of storage cargo grids can be designed, and the material storage density is increased by about 50%.
