[0020] The present invention will be further described below with reference to the accompanying drawings. A lifting tool for a container ship hatch cover includes a frame 1, with a connecting part 2 on the upper end face of the frame for connection with lifting equipment, and a plurality of locks 3 on the lower end face of the frame for detachable connection with a container. It also includes an intermediate shaft 4, rotatably connected to the frame; an operating part 41 located on the circumferential outer wall of the intermediate shaft for manual operation to drive the intermediate shaft to rotate; a transmission rod 5 that moves back and forth when the intermediate shaft rotates; levers 51 located at both ends of the transmission rod; and movable grooves 31 located on the upper end face of the locks, with part of the levers extending into the movable grooves and driving the locks to rotate when the transmission rod moves back and forth. The operating principle of the locks is the same as existing technology, i.e., the locks rotate and the locking tongue extends into the insertion hole on the container to achieve locking, and then the lifting tool is lifted by the lifting equipment. The feature of this application is that the rotation of the intermediate shaft can drive the movement of multiple locks, at least two, and generally four. The two levers at both ends of the transmission rod are for simultaneously driving two locks. The connecting part can be a connecting plate with connecting holes.

[0021] In this embodiment, as shown in the figure, the frame includes two horizontal tubes 11, and the transmission rod is disposed inside the horizontal tubes. The horizontal tubes are arranged perpendicularly to the intermediate shaft, and the horizontal tubes are provided with circular holes for rotatable installation of the intermediate shaft.

[0022] In this embodiment, as shown in the figure, a shaft hole 111 is provided on the wall of the horizontal tube. The lock is rotatably connected to the shaft hole, and a locking tongue 32 is provided on the lock extending out of the shaft hole. Part of the lock is inside the horizontal tube, and part is outside the horizontal tube. The part outside the horizontal tube is provided with a locking tongue for connecting to the insertion hole on the container.

[0023] In this embodiment, as shown in the figure, the lock located inside the horizontal tube has a movable groove. Specifically, the movable groove can be formed by providing an annular wall on the upper end face of the lock, and placing the movable groove within it.

[0024] In this embodiment, as shown in the figure, one end of the intermediate shaft is rotatably connected to one of the horizontal tubes, and the other end is rotatably connected to another horizontal tube.

[0025] In this embodiment, as shown in the figure, a crank 41 is provided on the intermediate shaft, and a short shaft 42 is provided on the crank; a connecting plate 55 is provided on the circumferential outer wall of the transmission rod, and a long groove 551 is provided on the connecting plate. The short shaft extends into the long groove and cooperates with the long groove. When the intermediate shaft rotates, it drives the crank to rotate. One end of the crank is provided with a short shaft, which drives the mounting plate to move back and forth (there will be some up and down movement, which does not affect the operation, as there is space between the bottom of the lever and the bottom inner wall of the movable groove). The mounting plate drives the transmission rod to move back and forth, and the lever contacts the lateral inner wall of the movable groove, causing the lock to rotate. The lever and the transmission rod can be connected by welding or other methods. The crank can be installed on the axial outer wall of the intermediate shaft with screws.

[0026] In this embodiment, as shown in the figure, the operating part is a triangular plate-shaped structure.

[0027] In this embodiment, as shown in the figure, the frame further includes a middle plate 15, which is disposed below the operating part to limit the rotatable angle of the operating part.

[0028] In this embodiment, as shown in the figure, there are two transmission rods, which are respectively located on both sides of the intermediate shaft.
