Description

Technical Field

[0001] This invention belongs to the technical field of lifting devices, and particularly relates to a lifting device for container ships. Background Technology

[0002] Container ships are vessels specifically designed for transporting standardized containers. Their design and function revolve around the efficient loading, transport, and unloading of containers. Most light industrial manufactured goods are well-suited for container transport, and their relatively low cost and relatively high transport quality make them irreplaceable in the global logistics industry. Due to the large volume of goods they carry, container ships require specialized lifting equipment for loading and unloading, such as quay cranes and gantry cranes. Workers need to use cranes to lift containers from the ship one by one and then place them in designated locations. Depending on the type of contents and country of origin, operators need to place them in different areas of the yard. In addition, there are also occasional customs inspections. Containers from the same batch may need to be placed in different areas of the yard. Currently, in most cases, ground operators use walkie-talkies to remind crane operators where to place the containers in the yard. During the operation, the operators are directed by the operators. Therefore, if the operator or the operator makes a mistake or loses focus, the operator may unload the container in the wrong location, which will affect the normal progress of subsequent loading and unloading operations.

[0003] To address this issue, we propose a container ship lifting device. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a container ship lifting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A container ship lifting device includes a crane, a boom installed in the crane, an indicator plate installed in the boom, a plurality of indicator lights installed on the indicator plate, each of the indicator lights being controlled by a controller located at the bottom of the indicator plate, a plurality of bearings provided on the indicator plate, each bearing located outside a corresponding indicator light, a transparent cover installed on the top of the bearing, a light-shielding sheet installed on the side wall of the transparent cover, the indicator lights located inside the transparent cover, a servo motor installed at the bottom of the indicator plate, and a rotation mechanism for driving the transparent cover to rotate installed at the output end of the servo motor.

[0006] Preferably, the area of ​​the light-shielding sheet occupies one-quarter of the area of ​​the transparent cover, the light-shielding sheet is a bright reflective sheet, and the top of the transparent cover is provided with a dome.

[0007] Preferably, the rotating mechanism includes a turntable, an eccentric rod, a hollow rod, a push rod, several rotating rods, several swing rods, several connecting shafts, several drive bevel gears, and several transmission bevel gear rings. The turntable is located at the output end of the servo motor. The eccentric rod is eccentrically mounted on the top of the turntable. The hollow rod is vertically mounted at one end of the push rod and is located inside the hollow rod. Several rotating rods are rotatably connected to the side wall of the push rod. The controller controls the rotation of several rotating rods. A fixed plate is installed at the bottom of the indicator plate. Several connecting shafts pass through the side wall of the fixed plate. Several swing rods are fixedly connected to several connecting shafts. A groove is opened on the side wall of the swing rod, and the rotating rod is located in the groove. The other end of the connecting shaft is fixedly connected to the side wall of the drive bevel gear. The transmission bevel gear ring is fixedly connected to the bottom of the bearing and meshes with the drive bevel gear.

Detailed Implementation

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0014] like Figure 1 - Figure 4 As shown, a container ship lifting device includes a crane 1, a boom 2 installed in the crane 1, an indicator plate 3 installed in the boom 2, and several indicator lights 4 installed on the indicator plate 3. The indicator lights 4 are controlled by a controller 5. The color of the indicator lights 4 can be customized, preferably a bright color such as orange or red. The controller 5 is located at the bottom of the indicator plate 3. Several bearings 6 are provided on the indicator plate 3, each bearing 6 located outside the corresponding indicator light 4. A transparent cover 7 is installed on the top of the bearing 6, and a light-shielding sheet 9 is installed on the side wall of the transparent cover 7. The indicator lights 4 are located inside the transparent cover 7. The area of ​​the light-shielding sheet 9 occupies one-quarter of the area of ​​the transparent cover 7. The light-shielding sheet 9 is a bright reflective sheet. A dome is provided on the top of the transparent cover 7. When the transparent cover 7 rotates, the light-shielding sheet 9 causes the indicator lights 4 to flash, making it easier to attract the operator's attention and further guiding the operator.

[0015] A servo motor 8 is also installed at the bottom of the indicator plate 3. A rotation mechanism for driving the transparent cover 7 to rotate is installed at the output end of the servo motor 8. The rotation mechanism includes a turntable 10, an eccentric rod 11, a hollow rod 12, a push rod 13, several rotating rods 14, several swing rods 15, several connecting shafts 16, several drive bevel gears 17, and several transmission bevel gear rings 18. The turntable 10 is located at the output end of the servo motor 8. The eccentric rod 11 is eccentrically installed on the top of the turntable 10. The hollow rod 12 is vertically installed at one end of the push rod 13. The push rod 13 is slidably connected to the bottom of the indicator plate 3. The eccentric rod 11 is located inside the hollow rod 12. The hollow rod 12 has a long strip-shaped hole inside. The length of the hole is twice the distance from the eccentric rod 11 to the center of the turntable 10. When the turntable 10 rotates, the eccentric rod 11 will drive the hollow rod 12 and the push rod 13 to reciprocate along the axial direction of the push rod 13, thereby driving the transparent cover 7 to rotate.

[0016] Several rotating rods 14 are rotatably connected to the side wall of the push rod 13. The controller 5 controls the rotation of the rotating rods 14. A fixed plate 19 is installed at the bottom of the indicator plate 3. Several connecting shafts 16 pass through the side wall of the fixed plate 19. Several swing rods 15 are fixedly connected to the connecting shafts 16. A groove 20 is opened on the side wall of the swing rod 15. The rotating rod 14 is located in the groove 20. The groove 20 is located at the lower end of the swing rod 15. The end of the groove 20 facing the servo motor 8 is open. The orientation of the groove 20 needs to be consistent with the rotation direction of the rotating rod 14, so that the rotating rod 14 can easily leave or enter the groove 20. The other end of the connecting shaft 16 is fixedly connected to the side wall of the drive bevel gear 17. The transmission bevel gear ring 18 is fixedly connected to the bottom of the bearing 6. The transmission bevel gear ring 18 meshes with the drive bevel gear 17. When the swing rod 15 drives the drive bevel gear 17 to rotate, it can drive the transmission bevel gear ring 18 and the transparent cover 7 to rotate together. This can attract the operator's attention and prevent rain and snow from accumulating on the transparent cover 7 in rainy or snowy weather.

[0017] The working principle is as follows: First, the ground control personnel transmit the location information of the container to the controller 5. The controller 5 then controls the corresponding number of indicator lights 4 to light up. At the same time, the controller 5 also controls the corresponding number of rotating rods 14 to rotate into the groove 20. Then, the servo motor 8 is started. The rotation of the servo motor 8 drives the turntable 10 to rotate. The eccentric rod 11 set on the turntable 10 drives the hollow rod 12 and the push rod 13 to reciprocate. This causes the rotating rod 14 set on the side wall of the push rod 13 to drive the swing rod 15 to swing back and forth. The connecting shaft 16 set on the side wall of the swing rod 15 drives the drive bevel gear 17 to rotate. The transmission bevel gear ring 18 meshing with it drives the bearing 6 to rotate. The transparent cover 7 set on the top of the bearing 6 will rotate, which serves to indicate to the operator.

[0018] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
