Embodiment Construction

[0018] Please refer to Figs. 1 to 3, the double 40-foot container spreader of the present invention is equipped with a closing and separating device whose structure is that the head ends of the two connecting rods 4a and 4b are hingedly connected by the pin shaft 7a, while the connecting rods 4a and 4b The middle section is hingedly connected with a double-headed oil cylinder 3 through pin shafts 7b and 7c, so that the two connecting rods 4a, 4b and a double-headed oil cylinder 3 form an isosceles A-shape; wherein, the connecting rod 4a is connected with the sea-side spreader through the pin shaft 7d. The swivel seat 2 on the upper frame 1 is hinged, and the connecting rod 4b is hinged to the swivel seat 5 on the upper frame 6 of the landside spreader through the pin shaft 7e, thereby forming a closing and separating device. The closing and separating device is set across between the upper frame 1 of the sea-side spreader and the upper frame 6 of the land-side spreader, and two...

Abstract

The invention relates the combining and separating unit used for double 40 feet sling, which is installed between sea side sling and earth side sling. The device has two connecting bars, the end of the two connecting bar are connected with each other by pin bearing, and the middle of them is connected with a double-end hydro-cylinder; the first rotation seat is installed on sea side sling, and the second rotation seat is installed on earth side sling; the first connecting bar is connected with the first rotation seat by pin bearing, and the second connecting bar is connected with the second rotation seat by pin bearing. The expansion and contraction motion of combining and separating unit realizes the combining and separating of two slings. The device possesses the advantages of simple structure, flexible, convenient and reliable combining and separating, and improving the efficiency.

Description

technical field [0001] The invention relates to a closing and separating device for putting on double 40-foot container spreaders. Background technique [0002] At present, a set of lifting mechanism of a port crane connected to a spreader can only lift one 40-foot container (two 20-foot containers) at a time, which restricts the improvement of production efficiency. The object of loading and unloading is one container on the ship, a truck It is a car. In order to further achieve efficient work efficiency, it is necessary to use a set of hoisting mechanisms to connect two spreaders and simultaneously lift two 40-foot containers (four 20-foot containers) at a time. Two 40-foot containers on the loading and unloading ship At this time, due to different ships, the spacing between the boxes is different, and the spacing between the two boxes on the deck and in the cabin of the same ship is also different; when two trucks are loaded and unloaded on the dock, the spacing between ...
