Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a rapid positioning and grabbing device for a container gantry crane. Background Art

[0002] Container gantry cranes, specialized gantry cranes for container terminals, railway freight stations, and storage yards, typically consist of a gantry mechanism, a trolley mechanism, a spreader mechanism, and a lifting mechanism. The spreader and lifting mechanism are both mounted on the trolley mechanism, which is driven by a drive device to move the spreader and lifting mechanisms on the gantry mechanism. The lifting mechanism typically consists of a reducer, a drum, and a pulley block. The lifting mechanism is connected to the spreader and trolley mechanism via wire ropes, utilizing the drive of the trolley mechanism and the function of the lifting mechanism to achieve cargo lifting.

[0003] Most existing gripping devices use a pneumatic clamping method, which is convenient, takes a short clamping time, and has a high degree of automation. However, if pneumatics are used as the clamping power, the problems of elongation and recovery of wire ropes, air pipes, and wires must be solved at the same time. Cranes use rollers to recover wire ropes, air pipes, and wires. The three relatively independent rollers will make the crane's lifting mechanism complicated and are more likely to interfere with each other. Utility Model Content

[0004] In order to solve the problem that the existing gripping device uses pneumatics as the clamping power structure, which is relatively complex and prone to mutual interference; the purpose of the utility model is to provide a container gantry crane rapid positioning and gripping device.

[0006] Preferably, a symmetrically distributed first positioning plate is fixedly provided on the upper surface of the fixed plate, a rotating rod is rotatably provided on the first positioning plate, a rotating wheel is fixedly provided on the end of the rotating rod away from the first positioning plate, a positioning rod is fixedly provided at the eccentric part of the rotating wheel, a third connecting plate is rotatably provided on the positioning rod, a connecting rod is rotatably provided on the end of the third connecting plate away from the positioning rod, the connecting rod is penetrated and provided on the second fixed block, and the end of the connecting rod away from the third connecting plate is fixedly provided on the first fixed block.

A second bevel gear 24 is rotatably provided on the lower surface of the second positioning plate 23, and the two first bevel gears 22 are meshed with the second bevel gear 24; when the second bevel gear 24 rotates, it will drive the two first bevel gears 22 to rotate in different directions.

[0020] A first motor 25 is fixedly mounted on the upper surface of the second positioning plate 23 . The output shaft end of the first motor 25 is fixedly mounted on the second bevel gear 24 . The second bevel gear 24 can be driven by the first motor 25 .

[0021] A bidirectional screw 26 is provided on the two second fixing blocks 15 for common rotation.

[0023] The two ends of the fixing plate 1 are fixedly provided with symmetrically distributed second positioning blocks 31 ; the second positioning blocks 31 can assist in positioning the container.

[0024] Both ends of the bidirectional lead screw 26 are fixedly provided with symmetrically distributed limit blocks 32; the limit blocks 32 can prevent the first positioning block 27 from detaching from the bidirectional lead screw.

[0025] Working principle: When in use, the staff can move the grabbing device to the top of the container, and then move the grabbing device downward. When the grabbing device contacts the container, the staff can start the second motor 29. Because the fourth bevel gear 3 is fixedly provided at the end of the output shaft of the second motor 29, the two second fixed blocks 15 are provided with a bidirectional screw 26 that rotates together, the bidirectional screw 26 is provided with symmetrically distributed first positioning blocks 27 on the thread, and the bidirectional screw 26 is fixed with a third bevel gear 28. The third bevel gear 28 and the fourth bevel gear 3 are meshed with each other. Therefore, when the second motor 29 is working, it will drive the two first positioning blocks 27 to move toward the fixed plate 1, thereby positioning the container so that the container is directly below the grabbing device.

[0026] When the container is positioned, the staff can start the first motor 25. Because the second bevel gear 24 is fixedly provided on the end of the output shaft of the first motor 25, the upper surface of the fixed plate 1 is fixedly provided with a symmetrically distributed first positioning plate 16, and the first positioning plate 16 is rotatably provided with a rotating rod 17.

The second bevel gear 24 and the two first bevel gears 22 are meshed with each other. Therefore, when the first motor 25 is working, it will drive the two rotating wheels 18 to rotate in opposite directions. A positioning rod 19 is fixedly provided at the center, a third connecting plate 2 is rotatably provided on the positioning rod 19, a connecting rod 21 is rotatably provided on the end of the third connecting plate 2 away from the positioning rod 19, and the end of the connecting rod 21 away from the third connecting plate 2 is fixedly provided on the first fixed block 14, and symmetrically distributed second connecting plates 13 are rotatably provided at both ends of the first fixed block 14, the end of the second connecting plate 13 away from the first fixed block 14 is rotatably provided with the first connecting plate 12, and the end of the first connecting plate 12 away from the second connecting plate 13 is fixedly provided with a clamping block 11.
