Problems solved by technology
[0003] The purpose of the present invention is to provide a horizontal misalignment device for double 40-foot container spreaders, so as to solve the problem of placing the containers on the two container trucks at the same time when there is a left-right deviation when the two container trucks are parked. Accurately lift or place the container hoisted by two spreaders on the two container trucks accurately

Embodiment Construction
[0018] see Figure 1 to Figure 4 As shown, the double 40-foot container spreader has a sea-side spreader upper frame 1 and a land-side spreader upper frame 7, and the two opening and closing mechanisms 4 are arranged across the sea-side spreader upper frame 1 and the land-side spreader upper frame 7, The opening and closing mechanism 4 is composed of two connecting rods, that is, the first connecting rod 4a and the second connecting rod 4b are hinged through the pin shaft 4c, and a double-headed oil cylinder 17 is respectively hinged with the first connecting rod 4a and the second connecting rod 4b. , the separation and closing mechanism 4 controls the separation and closing of the upper frame 1 of the sea-side spreader and the upper frame 7 of the land-side spreader. When the upper frame 1 of the sea-side spreader and the upper frame 7 of the land-side spreader need to be misaligned in the direction of the horizontal position, it will be realized by a horizontal misalignment ...

The invention aims to design a horizontal dislocation device for racking double 40-foot container spreaders. A sea-side horizontal dislocation oil cylinder is set up on the sea-side spreader, one end of which is hinged on the sea-side fixed seat through a pin shaft, and the other end is connected to the sea-side fixed seat through a pin. The shaft is hinged on the swivel arm of the sea-side rotating seat; similarly, the land-side spreader upper frame is also provided with a land-side horizontal dislocation cylinder, one end of which is hinged on the land-side fixed seat through a pin shaft, and the other end is hinged on the land-side through a pin shaft. on the swivel arm of the swivel base. The upper frame of the sea-side spreader and the upper frame of the land-side spreader are connected across the first link and the second link which are hinged with two head pin shafts. The present invention can accurately and quickly lift containers on two misplaced container trucks, or accurately place containers hoisted by two spreaders on the two misplaced container trucks. The device has the advantages of simple structure and easy operation. The advantages of flexibility, convenience and reliability, and improved work efficiency.
Description
technical field [0001] The invention relates to a double 40-foot container spreader for a port crane, in particular to a horizontal dislocation device for the spreader. Background technique [0002] At present, a set of hoisting mechanisms 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. In order to further achieve high working efficiency, a set of hoisting mechanism is adopted to connect two spreaders and lift two 40-foot containers (four 20-foot containers) at the same time. When a container truck has a left-right deviation when parking (that is, the two trucks are not aligned), how to accurately place the container hoisted by the two spreaders on the container truck, or how to accurately place the containers on the two container trucks at the same time lift. Contents of the invention [0003] The purpose of the present invention is to provide a hori...
