Heavy duty stacker for containers

Abstract

The invention discloses a heavy duty stacker for containers. The heavy duty stacker comprises a stacker frame, a safety protection device, a loading platform, a container hooking and taking device, a lifting device, an operation driving device and an electrical control device, wherein the stacker frame comprises four upright posts, an upper cross beam and a lower cross beam; the safety protection device comprises a cargo state detection device, a broken rope protection device, a power outage protection device, a travel speed-limiting device, a detection and positioning device and a progression speed reduction, walking emergency stop and retreat speed reduction switch; the container hooking and taking device comprises a lower fork, a middle fork, an upper fork and a hooking and taking driving mechanism composed of a normally closed electromagnetic braking motor, a chain wheel and a chain; the lifting device comprises a speed reduction motor, a pulley group, a steel wire rope reel, an encoder and a steel wire rope; and the operation driving device comprises a motor, a driving wheel, a driven wheel and an encoder. The heavy duty stacker is reasonable in structural design, strong in operability, good in safety performance and good in stable performance, and can meet the loading demand of large containers at ports and docks, and be convenient for popularization.

Description

technical field [0001] The invention relates to a stacker, in particular to a container heavy stacker. Background technique [0002] The stacker is the key lifting and handling equipment in the automatic three-dimensional warehouse. Its function is to move the material from the entrance and exit of the roadway to the designated cargo compartment within a limited time, or to move the material from the designated cargo compartment to the designated compartment of the roadway. import and export. Whether the stacker can operate safely, reliably, stably, and efficiently is directly related to the success of the design of the entire three-dimensional warehouse system. The stacker is classified according to the scale, the height is below 10 meters for the low-level type, 10-20 meters for the middle-level type, and below 20 meters for the high-level type. According to the driving mode, it is divided into two types: the lower driving mode and the upper and lower driving mode. At p...

Problems solved by technology

At present, most of the stackers used in my country have a load capacity of about 0.5 tons to 5 tons, but in port terminals, there are often large containers that need to be stored in three-dimensional warehouses, and the existing stackers with a load capacity of 5 tons are far away. It cannot meet the needs of actual use. Moreover, the existing stacker cranes with large loads still have the disadvantages of low safety performance and poor stability performance, which seriously affect the efficiency of container access and cargo transportation. Sometimes It will also cause unnecessary economic losses due to the poor performance of the stacker, damage to the goods or delay in the transportation of the goods
