Abstract

The embodiment of the invention provides a connecting device for dual hanger top racks, and a crane and relates to the technical field of hoisting equipment. The connecting device for the dual hanger top racks comprises a first hanger top rack, a second hanger top rack and a mechanical hand connecting mechanism, wherein two ends of the mechanical hand connecting mechanism are connected to the first hanger top rack and the second hanger top rack, respectively. The mechanical hand connecting mechanism comprises a first arm frame and a second arm frame which are mutually hinged, wherein the first arm frame and / or the second arm frame can be moved in a telescopic manner so as to realize at least two types of different relative motion of the first hanger top frame and the second hanger top frame. The mechanical hand connecting mechanism has a large extending length, can be folded and has a large adjustment scope. Adjacent containers on the same layer can be assembled and disassembled with conventional dual 40-foot hanger top racks; containers can be assembled and disassembled alternately; containers on different layers can be assembled and disassembled; flexibility is high; and efficiency of the crane can be greatly increased.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a double-sling upper-frame connecting device and a crane. Background technique [0002] At present, the loading and unloading of double 40-foot containers mostly uses the container spreader connection device for operation. Specifically, the sea-side and land-side spreaders are connected and combined by 8 or 10 oil cylinders to realize various loading and unloading of double 40-foot containers. Working conditions, when realizing various actions, rely on the electrical control system to detect and control the cylinder movement in real time to ensure the synchronization of the same action and prevent damage to the structure and cause failure. [0003] Since the hanger loading and connecting device of the existing structure can only load and unload containers on the same floor and adjacent positions, the flexibility is poor and the working conditions are limited.
