Abstract
Description
Technical Field
[0001] This application relates to the field of crane lifting equipment technology, and in particular to an inner guide plate for a lifting equipment. Background Technology
[0002] With the continuous expansion of economic globalization and international trade, container shipping plays an increasingly important role in global trade. Containers are used in large quantities, and container handling operations are becoming more and more frequent when retrieving containers. When the spreader is handling the container in the middle, it often bumps into the surrounding containers. There is currently no good solution for handling the inner container, so it needs to be improved. Utility Model Content
[0003] To improve the problem of frequent collisions with surrounding containers when the spreader is flipping and retrieving a container located in the middle, and to protect the structural safety of the container, this application provides an internal guide plate for the spreader.
[0004] The technical solution for the inner guide plate of the lifting device provided in this application is as follows: A spreader inner guide plate includes a guide plate mechanism disposed on the spreader. The spreader includes two crossbeams arranged along the length of a container and a connecting beam disposed at both ends of the crossbeams for connecting the two crossbeams. Both ends of the connecting beam extend beyond the adjacent crossbeams. The guide plate mechanism is disposed on the inner wall of the connecting beam extending beyond the crossbeams. The guide plate mechanism includes a base, a guide plate, a connecting rod, a crank, and a power component. The base is connected to the inner wall of the connecting beams. The guide plate is rotatably connected to the base. One end of the connecting rod is rotatably connected to the guide plate. The crank is rotatably connected to the end of the connecting rod away from the guide plate. The other end of the crank is rotatably connected to the end of the base away from the guide plate. The power component is disposed on the side wall of the base. The output shaft of the power component is connected to the hinge joint between the crank and the base. The power component is used to drive the crank to rotate.
[0005] By adopting the above technical solution, when the spreader grabs a container surrounded by other containers, the bottom of the guide plate will enter the container opening during the lowering process of the spreader. The guide plate acts as a guide, allowing the entire spreader to smoothly enter the container. This avoids the problem of frequently bumping into the surrounding containers when flipping and retrieving the container in the middle, thus protecting the structural safety of the container and the spreader. After the spreader is fully inside the container, the power unit is activated. Through the transmission relationship of the connecting rod and crank, the guide plate is rotated relative to the base, exposing the container lock on the spreader. After the lock contacts the container feet, it locks the container, and the container is lifted out. This allows for quick container flipping without removing the surrounding containers, greatly saving flipping time and improving work efficiency. Preferably, the base has a base plate on the side facing the connecting beam, and the base plate has a first fastener for fixing the base plate to the connecting beam.
[0006] By adopting the above technical solution, a detachable connection is formed between the guide plate mechanism and the connecting beam, which facilitates the quick installation or disassembly of the guide plate mechanism and improves the convenience of subsequent maintenance or replacement.
[0007] Preferably, the power component has a connecting plate on the side wall facing the crossbeam, and the connecting plate has a second fastener for fixing the connecting plate to the crossbeam.
[0008] By adopting the above technical solution, the power component can be connected to the crossbeam more stably, ensuring the stability of the power component when driving the crank to rotate.
[0009] Preferably, the top wall of the guide plate is provided with a relief groove, which covers the lower end of the connecting beam.
[0010] By adopting the above technical solution, the problem of collision between the guide plate and the connecting beam when the guide plate is in a vertical state can be effectively prevented, thereby effectively protecting the integrity and safety of the lifting equipment and the guide plate structure.
[0011] Preferably, the lower sidewall of the guide plate has a guide surface.
[0012] By adopting the above technical solution, the opening of the guide surface facilitates the bottom end of the guide plate to enter the container better, thus playing a guiding role and further improving the accuracy of the guide plate of this application.
[0013] Preferably, the base is bent, the top of the guide plate is hinged to the vertical section of the base, and the crank is hinged to the horizontal section of the base.
[0014] By adopting the above technical solution, the base is set in a bent shape, which facilitates the rotation of the guide plate, connecting rod and crank, and improves the smooth operation of the guide plate mechanism of this application.
[0015] Preferably, the base has a hollow interior, and the guide plate and crank are both hinged to the inner wall of the hollow structure of the base.
[0016] By adopting the above technical solutions, the base can be made lighter, thereby effectively reducing the weight of the overall lifting device and guide plate, reducing the burden on the lifting mechanism, improving safety, and saving production costs.
[0017] Preferably, the guide plate has a hollow interior, and the connecting rod is hinged to the inner wall of the hollow structure of the guide plate.
[0018] By adopting the above technical solutions, the guide plate can be made lighter, thereby effectively reducing the weight of the overall lifting equipment and guide plate, reducing the burden on the lifting mechanism, improving safety, and saving production costs.
[0019] In summary, this application includes at least one of the following beneficial technical effects: 1. When the spreader grabs a container surrounded by other containers, the bottom of the guide plate will enter the container opening during the lowering process of the spreader. The guide plate will guide the spreader to enter the container smoothly, thus avoiding the problem of bumping into the surrounding containers when retrieving the container in the middle. This protects the structural safety of the container and the spreader. 2. Once the spreader is fully inside the container, the power unit starts, and through the transmission relationship of the connecting rod and crank, it drives the guide plate to rotate relative to the base, thereby exposing the container lock on the spreader. After the lock contacts the container feet, it locks the container and lifts it out. This allows for quick container flipping without having to move surrounding containers, thus greatly saving flipping time and improving work efficiency. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.
[0027] This application discloses an inner guide plate for a lifting device. (Refer to...) Figure 1 and Figure 2 The spreader 1 includes guide plate mechanisms 2 located at the four corners of the spreader 1. In this embodiment, the spreader 1 includes two crossbeams 11 arranged along the length of the container and connecting beams 12 located at both ends of the crossbeams 11 for fixing the two crossbeams 11. The crossbeams 11 and the connecting beams 12 are fixedly connected by welding. Both ends of the connecting beams 12 extend beyond the crossbeams 11. The guide plate mechanism 2 is located on the inner wall of the portion of the connecting beams 12 that extends beyond the crossbeams 11.
[0028] Reference Figure 2 , Figure 3 and Figure 4 The guide plate mechanism 2 includes a base 21, a guide plate 22, a connecting rod 23, a crank 24, and a power component 25. The base 21 is bent and includes a vertical section and a horizontal section. A base plate 211 is welded to the side wall of the vertical section of the base 21. A first fastener 212 is provided on the base plate 211. The first fastener 212 is used to fix the base plate 211 to the connecting beam 12. In this embodiment, the first fastener 212 includes a flat washer and a bolt. The guide plate mechanism 2 is fixed to the connecting beam 12 by a detachable connection, which improves the installation or disassembly efficiency.
[0029] Reference Figure 2 and Figure 3 The base 21 has a hollow interior. The guide plate 22 is located below the base 21. The top of the guide plate 22 is hinged to the inner wall of the hollow structure of the vertical section of the base 21 via a shaft. The top wall of the guide plate 22 has a clearance groove 221. When the guide plate 22 is not rotating relative to the base 21, the clearance groove 221 covers the bottom wall and inner wall of the connecting plate 251. The lower side wall of the guide plate 22 has a guide surface 222 to guide the guide plate 22 when it enters the container. In this embodiment, the size of the rectangle formed at the bottom of the guide plate 22 is smaller than the size of the container.
[0030] Reference Figure 3 , Figure 4 and Figure 5 The guide plate 22 has a hollow interior. One end of the connecting rod 23 is hinged to the hollow inner wall of the guide plate 22, and the crank 24 is hinged to the other end of the connecting rod 23. The other end of the crank 24 is hinged to the inner wall of the horizontal section of the base 21. The power component 25 is located on the outer wall of the horizontal section of the base 21. In this embodiment, the power component 25 is a motor, and its output shaft is connected to the hinge point between the crank 24 and the base 21 to drive the crank 24 to rotate, thereby driving the guide plate 22 to rotate through the transmission of the connecting rod 23.
[0031] Reference Figure 2 and Figure 5A connecting plate 251 is provided on the side wall of the power component 25 facing the crossbeam 11. A second fastener 252 is provided on the connecting plate 251 to fix the power component 25 to the side wall of the crossbeam 11, thereby improving the stability of the power component 25 during operation. In this embodiment, the second fastener 252 includes a flat washer and a bolt, and the power component 25 is fixed to the crossbeam 11 by a detachable connection, thereby improving the installation or disassembly efficiency.
[0032] The implementation principle of the guide plate inside the spreader in this embodiment is as follows: When the spreader 1 grabs the container surrounded by other containers, during the lowering process of the spreader 1, the bottom end of the guide plate 22 will enter the container opening. The guide plate 22 plays a guiding role, allowing the entire spreader 1 to smoothly enter the container. This avoids the problem of frequently bumping into the surrounding containers when flipping and retrieving the container in the middle, thus protecting the structural safety of the container and the spreader 1. After the spreader 1 is completely inside the container, the power component 25 is activated. Through the transmission relationship between the connecting rod 23 and the crank 24, the guide plate 22 is rotated relative to the base 21, thereby exposing the container lock on the spreader 1. After the lock contacts the container feet, it locks the container and lifts it out. This allows for quick flipping without removing the surrounding containers, greatly saving flipping time and improving work efficiency.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
