[0002] With the continuous growth of container throughput, in order to reduce the transportation cost of containers, container ships are constantly developing towards larger sizes, which requires ports to have higher assembly efficiency. Container safety, as a key loading and unloading equipment at container terminals, directly operates on ships and plays an important role in the overall loading and unloading efficiency of the terminal.

[0003] The lifting device of the container quay crane in the prior art is prone to top collision when the lifting height of the lifting rope is too high, and the anti-top collision effect is poor. In addition, the lifting device of the existing container quay crane has a certain safety hazard due to the excessively large inclination angle of the lifting rope. When the inclination angle of the lifting rope is too large, it is not convenient to alarm and remind the surrounding staff. A lifting device for a container quay crane is now invented to solve the above problems. Utility Model Content

A convex slide groove is opened on the top of the second rectangular frame 8 with the up-down direction as the depth direction and the front-back direction as the length direction. The end of the convex sliding block 13 is located inside the convex slide groove, and the convex sliding block 13 can slide along the length direction of the convex slide groove. The end of the buffer spring 14 is installed inside the convex slide groove. The bottom of the first rectangular frame 5 is respectively installed with a matching block 9, a damper 10 and a first contact switch 11, one side of the matching block 9 is rotatably connected to a support rod 12 through an axis rod, and one side of the support rod 12 is rotatably connected to a convex sliding block 13 through an axis rod. A buffer spring 14 is installed on one side of the convex sliding block 13, and a first contact block 15 is installed on the top of the second rectangular frame 8. The position of the first contact block 15 corresponds to the position of the first contact switch 11, and the position of the second contact block 22 corresponds to the position of the second contact switch 20. A first alarm 16 is installed in front of the connecting rod 4.

[0026] When in use, when lifting the container, the electric hoist 3 works to reel in the lifting rope 24. When the lifting block 25 on the lifting rope 24 abuts against the cylinder 18, the second rectangular frame 8 is subjected to an upward force, so that the distance between the first rectangular frame 5 and the second rectangular frame 8 becomes smaller, and the guide rod 7 moves along the length direction of the guide ring 6. The movement of the second rectangular frame 8 provides a component force in the lateral direction for the support rod 12, so that the support rod 12 rotates within a certain range.
