Abstract
The utility model relates to a single-double container conversion device of container spreader, which is arranged on the middle portion of a spreader fixed mount, and comprises an electric system device, a hydraulic system device and a pair of hoisting mechanisms, wherein each hoisting mechanism comprises a hoisting oil cylinder, a hoisting beam, a rotary pin oil cylinder, a middle locking mechanism, a single-container limit switch and a double-container limit switch, wherein on end of the hoisting oil cylinder is connected with the spreader fixed mount, and the other end thereof is connected with the hoisting beam which is connected with the spreader fixed mount through a pin shaft, the middle locking mechanism is arranged on the hoisting beam, the rotary pin oil cylinder is connected with the middle locking mechanism, and the other end of the rotary pin oil cylinder is fixed on a hosting beam retaining plate which is integrated with the hoisting beam. The single-double container conversion device not only can load and unload a single container, but also can simultaneously load and unload two 20-inch containers, increases the loading and unloading efficiency, and has flexible operation and more adaptability.
Description
Technical field
The utility model relates to container handling crane tool field, especially relates to a kind of two case transfer devices of list of container spreader.
Background technology
At present the container spreader of each big harbour carries out container crane when unloading, usually suspender can only hang one by one freight container and unload, and can waste production time like this, can not faster carry out hanging of freight container and unload, taken the length of the halt of boats and ships, influenced stevedoring efficient at the harbour.
Summary of the invention
The purpose of this utility model is the above-mentioned shortcoming at prior art, and a kind of two case transfer devices of list of container spreader are provided.
The technical scheme that realizes the utility model above-mentioned purpose is: the two case transfer devices of the list of container spreader, be arranged on the middle part of suspender fixed mount, include the electric system device, hydraulic system and a pair of derricking gear, each derricking gear includes elevating ram, hanging beam, the oil cylinder of shipping and reselling on another market, middle latch mechanism, single case limit switch and two case limit switch, one end of elevating ram is connected with the suspender fixed mount, the other end links to each other with hanging beam, hanging beam links to each other with the suspender fixed mount by bearing pin, hanging beam is provided with middle latch mechanism, the oil cylinder of shipping and reselling on another market links to each other with middle latch mechanism, the other end be fixed on hanging beam be on the hanging beam adapter plate of one.
The two case transfer devices of the list of described container spreader, elevating ram all adopts bearing pin to be connected with suspender fixed mount and hanging beam, and the oil cylinder of shipping and reselling on another market adopts bearing pin to be connected with middle latch mechanism.
The utility model has the advantages that: solved the difficult problem that existing suspender elevator machinery can not load and unload two 20 feet freight container simultaneously, all functions with common single case, double-box hanger one, and maintenance is than being easier to, frame mode is fairly simple, the trouble point is few, fault is checked easily, does not waste production time, improves the handling efficiency of harbour.
Description of drawings
View when Fig. 1 is the two case of the utility model lifting;
Fig. 2 is the view of the utility model when lifting by crane single case;
Among the figure, 1 is the suspender fixed mount, and 2 is elevating ram, and 3 is hanging beam, and 4 are the oil cylinder of shipping and reselling on another market, and 5 is middle latch mechanism, and 6 is single case limit switch, and 7 is two case limit switches, and 8 is bearing pin, and 9 is the hanging beam adapter plate, and 10 is the electric system device, and 11 is hydraulic system.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model:
The two case transfer devices of the list of container spreader, be arranged on the middle part of suspender fixed mount 1, include electric system device 10, hydraulic system 11 and a pair of derricking gear, each derricking gear includes elevating ram 2, hanging beam 3, the oil cylinder 4 of shipping and reselling on another market, middle latch mechanism 5, single case limit switch 6 and two case limit switch 7, one end of elevating ram 2 is connected with suspender fixed mount 1, the other end links to each other with hanging beam 3, hanging beam 3 links to each other with suspender fixed mount 1 by bearing pin 8, hanging beam can rotate around bearing pin 8, hanging beam 3 is provided with middle latch mechanism 5, the oil cylinder 4 of shipping and reselling on another market links to each other with middle latch mechanism 5, the other end be fixed on hanging beam 3 on the hanging beam adapter plate 1 of one.Electric system device 10 control controlled hydraulic system devices 11, and act on a pair of derricking gear simultaneously.Single case limit switch 6 and two case limit switch 7 have detecting device.Elevating ram 2 all adopts bearing pin to be connected with suspender fixed mount 1 and hanging beam 3, and the oil cylinder 4 of shipping and reselling on another market adopts bearing pin to be connected with middle latch mechanism 5.After increasing the utility model on the single box hanger of routine, except finishing the lifting of conventional single box hanger, can also lift by crane two 20 feet empty van simultaneously, improve operating efficiency.When two 20 feet empty vans of lifting, as Fig. 1, effect by electric system device 10 controlled hydraulic system devices 11, the piston rod of elevating ram 2 stretches out, hanging beam 3 rotates around bearing pin 8 and descends, this moment, two case limit switches 7 detected signal, and latch mechanism 5 opened and closed the lock action during the oil cylinder 4 of shipping and reselling on another market can drive; When the single case of lifting, as Fig. 2, effect by electric system device 10 controlled hydraulic system devices 11, the piston rod withdrawal of elevating ram 2, hanging beam 3 rotates around bearing pin 8 and lifts, this moment, single case limit switch 6 detected signal, and oil cylinder 4 akinesias of shipping and reselling on another market are carried out crane lifting service by the lifting part of the single box hanger of routine.
