Description

Technical Field

[0001] This invention relates to the field of container equipment technology, and in particular to a centralized wind protection system for container equipment. Background Technology

[0002] Container quay cranes (commonly known as port quay cranes or container cranes) are specialized equipment used for loading and unloading containers at port terminals. To ensure the safe and stable operation of container quay cranes under various environmental conditions and to improve the overall efficiency and safety of port operations, the equipment is typically equipped with windproof and anchoring devices. The anchoring devices are generally fixed to the lower crossbeam on the sea or land side of the container quay crane, or to the side below the crane's traveling mechanism. They take the form of anchor plates or anchor pins and are used to horizontally anchor the quay crane against wind loads when it is not in operation.

[0003] In conventional wind protection solutions for container equipment, during storms, windproof cables are typically fixed to pre-buried cable pits in the ground to resist the upward force generated by the storm. Current technology generally configures windproof cables such that for the wind protection needs of a single piece of equipment or two adjacent pieces of equipment, each windproof cable is connected to a cable pit to achieve uplift resistance. However, in actual engineering projects, some terminals failed to reserve enough cable pits during the initial planning, resulting in insufficient independent cable pits for each or every two pieces of equipment when multiple pieces of equipment need to be added later. Modifying existing terminals not only involves high civil engineering costs and a long construction period but also severely impacts normal ship unloading operations. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a centralized wind protection device, system and construction method for container equipment.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: An embodiment of the present invention provides a centralized wind protection system for container equipment, comprising: At least three container units are arranged side by side, with the two outermost units being end units and at least one unit between the end units being intermediate units; The end device is equipped with windproof cables for fixing to the ground foundation; The end device is also provided with a first force transmission component; The intermediate device is equipped with a second force transmission component; The first force transmission component and the second force transmission component are interlocked in the horizontal direction and form a vertical force-bearing surface cooperation. When a storm generates an upward force, the upward force of the intermediate device is transmitted to the first force transmission component through the second force transmission component, and the upward force is transmitted to the ground foundation through the end device and its windproof cable.

[0006] The first force transmission component is a first L-shaped top block, which is fixed to the end device and has its free end bent downward; the second force transmission component is a second L-shaped top block, which is fixed to the intermediate device and has its free end bent upward.

[0007] Further configured, the first L-shaped top block has an arc-shaped surface at the bend, the second L-shaped top block has an arc-shaped surface at the bend, and the upper surface of the free end of the second L-shaped top block and the lower surface of the free end of the first L-shaped top block are in contact after installation to form an S-shaped top block structure.

[0008] The device is further configured such that the first L-shaped top block is elongated and continuously disposed along the side wall of the end device, and the second L-shaped top block is elongated and continuously disposed along the side wall of the intermediate device.

[0009] The design further specifies that the contact surface between the first L-shaped top block and the second L-shaped top block is a plane, and the normal direction of the plane is parallel to the vertical direction, thereby transmitting the upward pulling force in the vertical direction.

[0010] The first force transmission component is a recessed block disposed inside the end device, and the second force transmission component is a protrusion disposed on both sides of the intermediate device; the protrusion is inserted into the recessed block to form a concave-convex mating structure.

[0011] A further configuration is that the concave block is elongated and continuously disposed along the side wall of the end device, and the protrusion is elongated and continuously disposed along the side wall of the intermediate device.

[0012] A further configuration is that the inner wall of the concave block is an inclined surface, and the convex block is provided with an inclined surface adapted to the inclined surface.

[0013] Secondly, the present invention provides a construction method for a centralized windproof system for container equipment, as detailed below: Includes the following steps: Step 1: Move the outermost end device using the bottom wheel assembly and secure it to the ground cable pit using the windproof cable on it; Step 2: Move the intermediate device next to the end device so that the second force transmission component on the intermediate device and the first force transmission component on the end device form a mutually interlocking contact in the vertical direction; Step 3: When encountering a storm, the upward force on the intermediate equipment is transmitted to the end equipment through the mating surface of the second force transmission component and the first force transmission component, and is borne by the windproof cables of the end equipment, thereby achieving centralized wind protection. Thirdly, the present invention provides a container equipment, specifically as follows: The container equipment, as an intermediate or end device, is applied in the centralized windproof system of the container equipment. The container equipment is equipped with a first force transmission component or a second force transmission component for transmitting upward force with adjacent equipment.

[0014] The beneficial effects of this invention are as follows: This invention utilizes a mechanical force transmission structure between devices to create a collaborative force-bearing system. It shifts the reliance on ground-based cable anchors to the force transmission path within the equipment cluster. End containers are secured by cables, while intermediate containers, through force transmission components and S-shaped or concave-convex block structures, precisely transmit vertical upward forces from the intermediate to the end devices. This changes the traditional isolated force-bearing mode of "single machine, single anchor," forming a collaborative force-bearing system. Multiple devices are connected through the force transmission structure to jointly resist the upward forces generated by storms. Without modifying the wharf, affecting operations, or increasing civil engineering costs, this invention solves the problem of limited equipment additions due to insufficient initial planning by utilizing the equipment's own structure and the mechanical coordination between devices. Simultaneously, it achieves reliable transmission of upward force resistance and system synergy. Attached Figure Description

[0022] Example 1: In a typical embodiment of the present invention, a centralized wind protection system for container equipment is provided.

[0023] Traditional wind protection solutions for container equipment are essentially an "infrastructure-oriented" model, meaning that the uplift resistance of each piece of equipment is highly dependent on whether there are enough pre-installed cable anchor points on the ground, resulting in a rigid "one-to-one" binding relationship between the equipment and the infrastructure. This model reveals significant shortcomings in adaptability when faced with insufficient initial planning at the terminal and subsequent equipment upgrades. This application breaks through this mindset by proposing a new "equipment collaboration-oriented" wind protection concept—through mechanical force transmission structures between equipment, multiple pieces of equipment form a synergistic force-bearing system, shifting the dependence on uplift resistance from "ground anchor points" to "force transmission paths within the equipment cluster." This conceptual shift provides a completely new solution for wind protection technology for port equipment. To achieve reliable transmission and system coordination of upward pulling force, an S-shaped top block structure or a concave-convex block structure is used to accurately transmit the vertical upward pulling force from the intermediate device 2 to the end device 1. The force transmission path is clear and well-defined, avoiding coupling interference of horizontal forces, resulting in an ideal structural stress state that facilitates engineering calculations and safety assessments.

[0024] System-wide collaborative uplift resistance: This system changes the traditional isolated force-bearing mode of "single machine and single anchor" and forms a collaborative force-bearing system of equipment clusters. Multiple devices are connected as one through the force transmission structure to jointly resist the uplift force generated by the storm. This allows the limited windproof cable resources to be used in a concentrated manner. The overall uplift resistance is not weakened by the absence of cables in the intermediate device 2, and the system redundancy and reliability are improved.

[0025] High reliability of force transmission structure: The force transmission component (L-shaped top block) is integrated with the equipment body, with no additional vulnerable connecting parts or moving parts. The force transmission path is stable and reliable under storm conditions, with excellent maintenance-free performance, and is suitable for the harsh environment of long-term outdoor operation of port equipment.

[0026] Example 1: Provides a centralized wind protection system for L-shaped top block container equipment, referring to Figure 1 , Figure 2 and Figure 5It includes three container quay cranes arranged side by side. The two on the far left and far right are end cranes 1, and the one in the middle is the middle crane 2.

[0027] Two windproof cables 6 are respectively installed on the lower crossbeam on the landside of each end device 1. One end of the windproof cable 6 is fixedly connected to the body of the end device 1, and the other end is connected to the cable pit 7 pre-embedded in the ground through a shackle. The end device 1 is also equipped with a first force transmission component 3, which is a first L-shaped top block 31 made of high-strength steel. It is long and strip-shaped and is continuously welded and fixed along the entire length of the side wall of the end device 1. The first L-shaped top block 31 includes a vertical section connected to the side wall of the device and a horizontal section that bends downward at its free end. The bend is set as an arc surface to eliminate stress concentration.

[0028] The intermediate equipment 2 is equipped with a second force transmission component 4, which is a second L-shaped top block 32. It is also made of high-strength steel, is long and strip-shaped, and is continuously welded and fixed along the entire length of both side walls of the intermediate equipment 2. The second L-shaped top block 32 includes a vertical section connected to the side wall of the equipment and a horizontal section that bends upward at its free end. The bend is also set as an arc surface.

[0029] During installation, first, move the left end device 1 to the predetermined position using the bottom wheel assembly 5, and securely connect its windproof cable 6 to the ground cable pit 7. Then, move the middle device 2 next to the left end device 1, aligning the second L-shaped top block 32 on the right side of the middle device 2 with the first L-shaped top block 31 on the right side of the left end device 1. Continue moving the middle device 2, gradually extending the upper surface of the free end of the second L-shaped top block 32 below the lower surface of the free end of the first L-shaped top block 31. Since both top blocks have curved surfaces at their bends, these surfaces act as guides during installation, allowing the two top blocks to smoothly engage.

[0030] When the free end of the second L-shaped top block 32 is fully inserted below the first L-shaped top block 31, the upper surface of the second L-shaped top block 32 and the lower surface of the first L-shaped top block 31 form a surface contact fit, at which point the two top blocks form an S-shaped top block structure 33. Following the same steps, the second L-shaped top block 32 on the left side of the right end device 1 and the middle device 2 are fitted together, and the windproof cable 6 of the right end device 1 is fixed to the ground cable pit 7.

[0031] When a storm generates an upward pulling force, the intermediate device 2 is subjected to this force. This force first acts on the body of the intermediate device 2 and is transmitted through the device structure to the second L-shaped top block 32. Since the upper surface of the second L-shaped top block 32 is in close contact with the lower surface of the first L-shaped top block 31, the upward pulling force is transmitted through this contact surface to the first L-shaped top block 31, and then to the body of the end device 1. After being subjected to the upward pulling force, the end device 1 transmits the force to the ground cable pit 7 through the windproof cable 6, and the ground foundation 8 bears the final upward pulling force.

[0032] During this process, the contact surface of the two L-shaped top blocks is a plane, and the normal direction of this plane is parallel to the vertical direction. Therefore, it only transmits the upward pulling force in the vertical direction and does not generate a horizontal component force. The arc-shaped surface design ensures that the force is evenly distributed at the bend, avoids stress concentration, and ensures the structural strength and long-term reliability of the force transmission component.

[0033] Example 2: This embodiment provides a bump-and-contour centralized windproof system, referencing... Figure 3 , Figure 4 and Figure 5 It includes four container quay cranes arranged side by side. The two outermost cranes are end cranes 1, and the two cranes between the end cranes 1 are intermediate cranes 2.

[0034] Each end device 1 is equipped with two windproof cables 6 for fixing to the ground cable pit 7. A first force transmission component 3, which is a recess 41, is provided on the inner wall of the end device 1. The recess 41 is made of high-strength steel, is elongated, and continuously extends along the entire length of the inner wall of the end device 1. The inner cavity of the recess 41 is open, and its inner wall surface is a slope 43, forming a guide slope 43.

[0035] Second force transmission components 4, which are protrusions 42, are provided on both side walls of the intermediate device 2. The protrusions 42 are also made of high-strength steel, are elongated, and are continuously arranged along the entire length of both side walls of the intermediate device 2. The shape of the protrusions 42 matches the inner cavity shape of the concave block 41, and inclined surfaces that are adapted to the inner inclined surfaces 43 of the concave block 41 are provided on both sides.

[0036] During installation, first move the left end device 1 to the predetermined position and fix its windproof cable 6 to the ground cable pit 7. Then move the first intermediate device 2 next to the left end device 1, aligning the protrusion 42 on the left side of the intermediate device 2 with the concave block 41 on the right side of the end device 1. Slowly move the intermediate device 2 so that the protrusion 42 gradually inserts into the concave block 41. Since the inner wall of the concave block 41 is a slope 43, and the protrusion 42 is provided with a corresponding slope 43, the slope 43 acts as a guide during insertion, guiding the protrusion 42 smoothly into the inner cavity of the concave block 41.

[0037] After the protrusion 42 is fully inserted into the concave block 41, the inclined surface of the protrusion 42 and the inclined surface 43 of the concave block 41 are tightly fitted together, forming a surface contact fit. Following the same steps, the second intermediate device 2 is fitted with the first intermediate device 2 in a concave-convex fit, then the right end device 1 is fitted with the second intermediate device 2 in a concave-convex fit, and finally the windproof cable 6 of the right end device 1 is fixed to the ground cable pit 7.

[0038] When a storm generates an upward force, both intermediate devices 2 are simultaneously subjected to an upward force. The upward force of each intermediate device 2 is transmitted through the device body to the protrusions 42 on both sides. The protrusions 42, through their contact with the inclined surfaces 43 of the concave blocks 41, transmit the upward force to the concave blocks 41 of the adjacent devices, and then gradually to the end devices 1 at both ends. The end devices 1 transmit the final upward force to the ground cable pit 7 through the windproof cables 6.

[0039] During this process, the inclined surface 43 mating structure not only ensures the reliable transmission of the upward pulling force, but also generates a self-locking effect, making the fit between the convex and concave blocks tighter and preventing them from disengaging due to vibration or external forces. The elongated, continuously arranged convex and concave blocks form a continuous mating surface along the length of the equipment sidewall, resulting in uniform stress distribution, high load-bearing capacity, and strong overall system reliability.

[0040] Example 3: This embodiment provides a construction method for a centralized wind protection system for container equipment, applicable to scenarios where the initial planning of the terminal lacks sufficient cable pit locations and multiple container units need to be added later. This method requires no modification to the terminal ground; system installation can be completed simply by moving the equipment and engaging the force transmission components.

[0041] The specific steps are as follows: Step 1: Positioning and fixing of end device 1 First, based on the actual distribution of the 7 cable pits at the dock, the placement of the end devices 1 is determined. The two outermost end devices 1 are moved to their predetermined positions along the track using the bottom wheel set 5. After the end devices 1 are in place, the pre-installed windproof cables 6 on them are connected to the ground cable pits 7. The ends of the windproof cables 6 are fixed to the anchor points in the cable pits 7 using shackles, and the cable preload is adjusted to the design value to ensure that the end devices 1 can withstand the expected upward pull.

[0042] Step 2: Installation of intermediate equipment 2 and engagement of force transmission components Move the first intermediate device 2 to the side of the end device 1 via the bottom wheel set 5, aligning the second force transmission component 4 on the intermediate device 2 with the first force transmission component 3 on the end device 1 in the horizontal direction. Slowly move the intermediate device 2 so that the second force transmission component 4 gradually embeds into the first force transmission component 3. During the embedding process, observe the relative positions of the force transmission components or use the guide structure to ensure that the two form a vertical force-bearing surface fit.

[0043] If an L-shaped top block structure is used, the upper surface of the free end of the second L-shaped top block 32 extends below the lower surface of the free end of the first L-shaped top block 31 until the two are completely fitted together. If a concave-convex block structure is used, the protrusion 42 is fully inserted into the concave block 41 until the inclined surface of the protrusion 42 is tightly fitted with the inclined surface 43 of the concave block 41. Following the same steps, the remaining intermediate devices 2 are installed in sequence, ensuring that the force transmission components between adjacent devices are fully engaged.

[0044] Step 3: System Acceptance and Windproof Application After installation, check the fit of each force transmission component to ensure that the contact surfaces are tightly fitted without any obvious gaps. In the event of a storm, the upward force on the intermediate device 2 is transmitted to the end device 1 through the mating surfaces of the second force transmission component 4 and the first force transmission component 3, and is borne by the windproof cable 6 of the end device 1, thus achieving centralized wind protection. After the storm, if disassembly is required, the operation can be performed in reverse order: remove the intermediate device 2, disengage the force transmission components, and the device will return to its independent state.

[0045] This construction method requires no excavation or modification of the wharf surface, avoiding any impact on normal wharf operations from civil construction. The entire installation process involves only the movement of equipment and the engagement of force transmission components, making it simple to operate, time-saving, and quick to complete during berth downtime. This method is suitable for wharfs built in phases or with gradually added equipment, demonstrating good engineering adaptability and economic efficiency.

[0046] Example 4: An example provides a container equipment, as detailed below: When the container equipment is used as end equipment 1, two windproof cables 6 are installed on the lower crossbeam on the sea side or land side of the equipment for fixing to the ground cable pit 7. The windproof cables 6 are made of high-strength steel wire rope, with one end hinged to the equipment body through a lug plate, and the other end equipped with a shackle for easy connection to the anchor point in the cable pit 7.

[0047] A first force transmission component 3 is provided on the inner wall of the equipment. This first force transmission component 3 can adopt an L-shaped top block or a concave block 41 structure as needed. When using an L-shaped top block, the first L-shaped top block 31 is elongated and continuously welded and fixed along the entire length of the inner wall of the equipment. Its free end is bent downwards, and an arc-shaped surface is provided at the bend. When using a concave block 41 structure, the concave block 41 is also continuously elongated, and its inner wall surface is a slope 43, forming a guide slope 43.

[0048] When the container equipment is used as intermediate equipment 2, the equipment does not need to be equipped with windproof cables 6, but second force transmission components 4 need to be installed on both side walls. The second force transmission component 4 matches the first force transmission component 3 and adopts an L-shaped top block or protrusion 42 structure.

[0049] When using an L-shaped top block, the second L-shaped top block 32 is elongated and continuously arranged along the entire length of both side walls of the equipment, with its free end bent upwards and an arc-shaped surface at the bend. When using a protrusion 42 structure, the protrusion 42 is elongated and continuously arranged, its shape matching the inner cavity of the concave block 41, and inclined surfaces on both sides adapted to the inclined surface 43 of the concave block 41.

[0050] The container equipment, as intermediate equipment 2 or end equipment 1, is applied in the centralized windproof system of the container equipment. The container equipment is equipped with a first force transmission component 3 or a second force transmission component 4 for transmitting upward pulling force to adjacent equipment.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
