Description

Technical Field

[0001] The utility model relates to the technical field of container lifting, in particular to a port container crane. Background Art

[0002] In port transportation, goods are usually loaded into containers, and then the containers are lifted onto cargo ships or trucks. However, since containers are rectangular in shape, they are not easy to lift during the lifting process. Therefore, holes are usually opened on the four corners of the containers to facilitate lifting. However, existing gantry cranes can only lift containers of specific sizes. For lifting containers of other specifications, since the force points are not at the four corners, the force is unbalanced during the lifting process and the stability is not strong.

[0003] Patent CN219526001U proposes a port container gantry crane. Through the arrangement of a suspension frame, a sliding hole, an adjusting rod, a baffle, an electric push rod, a U-shaped frame, a limiting sleeve, a positioning handle, a locking handle, a lifting rope and a hook, the staff can turn the locking handle according to the size of the suspended object, start the electric push rod, and the electric push rod drives the baffle to move, so that the distance between the baffles can be adjusted, and then the positioning handle is loosened to make the limiting sleeve slide on the U-shaped frame, so that the spacing between adjacent hooks on the same side can be adjusted, so that the position of the four hooks can be adjusted to match the size of the hoisted object, and objects of different specifications can be hoisted more stably.

[0004] In the above scheme, the front-to-back and left-to-right spacing of the hook can be adjusted to meet the needs of lifting containers of different sizes. However, since the suspension frame of the device is fixed, after the container is lifted, it cannot be transported to the truck. The vehicle needs to move to the bottom of the raised container to complete the transfer of the container, which affects the efficiency of the subsequent transportation of the container. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide a port container crane to solve the problems raised in the above-mentioned background technology. The utility model has a novel structure. Containers of different sizes can be suspended by adjusting the spacing between four sets of hooks through the lifting assembly, and the containers are lifted and hoisted by the winding seat. Subsequently, the rotating frame is rotated from a vertical state to a horizontal state, and the movable frame moves outward, driving the lifting assembly and the container to move outward, so as to facilitate their transportation to the transfer vehicle, thereby improving the lifting efficiency of the container.

[0006] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a port container crane, comprising a fixed frame, a mobile frame is provided at the front end of the fixed frame, and a pulley is installed at the bottom of the mobile frame, two sets of winding seats are installed on the top of the fixed frame, and the winding shaft in the winding seat is connected by an axle rod transmission, a traction rope is wound on the winding shaft of the winding seat, a lifting component is provided inside the fixed frame, and the lifting component includes a transverse frame, two sliders are symmetrically slidably connected inside the transverse frame, and a first plug rod is slidably inserted in one side of the slider, and a second plug rod is slidably inserted in the other side of the slider, and the directions of the first plug rod and the second plug rod are opposite, and the ends of the first plug rod and the second plug rod away from the transverse frame are fixed with a lifting rope, and a hook is fixed at the bottom of the lifting rope, and rotating frames are rotatably installed on both sides of the fixed frame through bearings, and the transverse frame slides along the rotating frame.

[0007] Furthermore, the lifting assembly also includes a bidirectional electric push rod, and the bidirectional electric push rod is fixed on both sides of the top of the cross frame, and the two extended ends of the bidirectional electric push rod are fixed to the slider.

[0008] Furthermore, the outer end of the transverse frame is fixedly connected to the movable frame via a connecting frame, and the outer ends of the first plug rod and the second plug rod are both slidably mounted with sliding frames.

[0009] Furthermore, a connecting block is slidably installed inside the rotating frame, and the other side of the connecting block is rotatably connected to the outer wall of the transverse frame through a bearing.

[0010] Furthermore, a second motor is fixed to the outer end of the fixing frame at a position corresponding to the rotating frame, and the output end of the second motor is fixedly connected to the rotating frame, and the bottom of the traction rope is fixed to the rotating frame.

[0011] Furthermore, the fixing frame is correspondingly fixed with a first motor, and the output end of the first motor is fixedly connected to the winding shafts of the two sets of winding seats.
