[0001] This application relates to the field of lifting machinery systems, and more particularly to an anchoring device and a crane. Background Technology

[0002] A crane is a mechanical device used to lift and move heavy objects, and it is widely used in industries such as construction, manufacturing, transportation, and logistics. Among them, rail-mounted cranes are currently the most efficient lifting equipment for loading and unloading containers on cargo ships. They are usually erected on port terminals, and to prevent displacement due to strong winds, anchoring devices are usually designed at the bottom of the crane.

[0003] The anchoring device is fixed to the dock fixing components in the anchoring pit next to the crane to lock the crane in place.

[0004] However, in the existing technology, the method of fixing the crane's anchoring device to the dock's fixed components is cumbersome. Utility Model Content

[0038] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0039] As mentioned in the background section, a rail-mounted crane is a lifting device installed on rails, typically used in situations requiring the movement of heavy objects along a fixed path. Rail-mounted cranes operate on pre-laid rails, which can be on the ground or elevated. The rails provide a stable path of movement, ensuring the crane can operate precisely within a designated area. Guided by the rails, rail-mounted cranes can move heavy objects quickly and smoothly, making them suitable for frequent loading and unloading operations. Rail-mounted cranes are typically designed to span large work areas and can lift and move very heavy objects.

[0040] Rail-mounted cranes are commonly used at docks, which are typically located in coastal areas and are frequently affected by sea and land breezes. During the day, the land warms up faster, causing air to rise and increasing the winds blowing from the ocean to the land; at night, the land cools down faster, causing air to sink and increasing the winds blowing from the land to the ocean. This diurnal wind cycle results in stronger winds in dock areas.

[0041] Rail-mounted cranes are large and easily moved or slid due to strong winds. To prevent displacement, anchoring devices are typically designed at the bottom of the crane. Traditional anchoring devices consist of a single anchor plate on one side of the rail or single anchor plates on both sides. The anchoring pit on the dock is positioned by manually controlling the crane's stopping position, and then the anchor plate is manually lowered. This traditional anchoring device design is unsuitable for dock designs with double anchor holes on one side of the rail, and it is cumbersome and inefficient.

[0042] In view of this, this application provides an anchoring device and a crane, which are suitable for wharves with double anchoring holes on one side of the track. By operating the control components, multiple hooks can move simultaneously to achieve rapid locking or releasing, reducing the complexity and time of manual operation. Multiple hooks are connected to the wharf fixing components at the same time, providing stronger anchoring force, especially improving the stability of the crane under strong wind conditions. This design is applicable to different types of wharf fixing components, without requiring additional modifications to the wharf, and has greater adaptability.

[0043] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0044] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0045] refer to Figures 1-2 This application provides an anchoring device, including a housing 100, a plurality of hooks 200 and a control component 300.

[0046] The hook part 200 is movably mounted on the housing 100.

[0047] The control element 300 is disposed in the housing 100, and the output end of the control element 300 is connected to a plurality of hook parts 200 to drive the plurality of hook parts 200 to move closer or further apart from each other.

[0048] When the control component 300 is in the first state, the multiple hook parts 200 approach each other and can connect with the fixing component 01. When the control component 300 is in the second state, the multiple hook parts 200 move away from each other and the hook parts 200 disengage from the fixing component 01.

[0049] It is understood that the housing 100 is the main frame of the anchoring device, housing and protecting the internal components. The housing 100 provides structural support and provides an installation platform for the multiple hooks 200 and control components 300.

[0050] The hook part 200 is a movable component designed for mechanical connection with the fixed part 01 at the dock. The hook part 200 moves to connect or disconnect from the fixed part 01, ensuring the stable positioning of the crane on the track.

[0051] The control component 300 is a drive assembly whose output end is connected to multiple hook parts 200. The control component 300 drives the movement of the hook parts 200 to realize the locking and releasing functions of the anchoring device.

[0052] With the above setup, multiple hooks 200 can move simultaneously using the operation of the control unit 300, enabling quick locking or releasing and reducing the complexity and time of manual operation. Multiple hooks 200 are connected to the dock fixing unit 01 at the same time, providing stronger anchoring force, especially improving the stability of the crane under strong wind conditions. This design is applicable to different types of dock fixing units 01, without requiring additional modifications to the dock, making it more adaptable.

[0053] In practical applications, in the first state, the control unit 300 drives multiple hooks 200 to move closer together and connect with the dock fixing member 01 to achieve anchoring. In the second state, the control unit 300 drives multiple hooks 200 to move away from each other, disengaging from the dock fixing member 01 to achieve release.

[0054] Specifically, the hook part 200 has two parts, making the anchoring device suitable for wharf designs with double anchoring holes on one side of the track.

[0055] In some possible implementations, the anchoring device further includes a connecting rod 400, which is rotatably connected to the housing 100.

[0056] The first end of the connecting rod 400 is connected to the output end of the control component 300, and the second end of the connecting rod 400 is connected to the hook part 200. The output end of the control component 300 can drive the hook part 200 to rotate through the connecting rod 400.

[0057] It is known that the connecting rod 400 is rotatably connected to the housing 100 and has a first end and a second end. The design of the connecting rod 400 enables it to transmit the movement of the control element 300 to the hook part 200, thereby realizing the functions of anchoring and releasing.

[0058] The housing 100 provides a support mounting platform for the connecting rod 400. The connecting rod 400 is rotatably connected to the housing 100. The housing 100 allows the connecting rod 400 to move within a certain range, converting the movement of the control component 300 into the rotation of the connecting rod 400 on the housing 100 to drive the hook part 200.

[0059] Therefore, through the design of the connecting rod 400, the control component 300 can efficiently transmit the driving force to the hook part 200, realizing rapid anchoring and release operations. The structure is simple and the operation is more convenient. The rotating connection design of the connecting rod 400 ensures the precise movement of the hook part 200, improving the reliability and stability of the anchoring device under strong wind conditions. Through a reasonable power transmission path, the dependence on other complex mechanical structures is reduced, improving the reliability of the system.

[0060] In some possible implementations, the output end of the control element 300 is provided with an extension 500, which is rotatably connected to the connecting rod 400.

[0061] It is understood that the extension 500 allows the movement direction of the control member 300 to be changed to the connecting rod 400, thus enabling the control member 300 to drive the connecting rod 400 more flexibly and achieve precise movement of multiple hooks 200 simultaneously.

[0062] This can be seen as the connecting rod 400 transmitting the motion of the control element 300 through the extension 500 to the hook part 200, enabling it to rotate and achieve locking or releasing. In the first state, the control element 300 drives the connecting rod 400 through the extension 500, causing the multiple hook parts 200 to move closer to each other and connect with the dock fixing element 01 to achieve anchoring.

[0063] In the second state, the control unit 300 drives the connecting rod 400 through the extension 500, causing the multiple hooks 200 to move away from each other and disengage from the dock fixing member 01, thus achieving release.

[0064] By using the extension 500, the connection between the control element 300 and the connecting rod 400 becomes more flexible, adapting to different operating angles and positions, thus improving the operational flexibility of the anchoring device. The extension 500 ensures that the driving force of the control element 300 can be effectively transmitted to the connecting rod 400, thereby improving the movement accuracy and anchoring stability of the hook 200. This design is applicable to the fixing element 01 of the dock with double anchoring holes on one side of the track, without requiring additional modifications to the dock, making it more adaptable.

[0065] In some possible implementations, the control element 300 is disposed inside the plurality of hook portions 200.

[0066] There are multiple extensions 500, and the output end of the control unit 300 drives multiple connecting rods 400 to rotate relative to the housing 100 through multiple extensions 500.

[0067] It is known that the control element 300 is located inside the hook part 200, so that one control element 300 can more directly drive the movement of multiple hook parts 200, providing more efficient operation.

[0068] The hook part 200 is a movable component designed to be mechanically connected to the dock fixture 01. It can be connected to or disconnected from the fixture 01 by moving, ensuring the stable positioning of the crane on the track.

[0069] There are multiple extensions 500, which are connected to the output end of the control unit 300. The multiple extensions 500 enable the control unit 300 to drive multiple connecting rods 400 simultaneously, ensuring the synchronous movement of the hook part 200.

[0070] The connecting rod 400 transmits the motion of the control element 300 through the extension 500 to the hook part 200, enabling it to rotate and achieve locking or releasing.

[0071] Therefore, by setting multiple extensions 500, the control element 300 can simultaneously drive multiple connecting rods 400, realizing the synchronous movement of multiple hooks 200, which significantly improves the operating efficiency; the control element 300 is set on the inner side of the hook 200, so that the driving force can be transmitted to the hook 200 more directly, which improves the reliability and stability of the anchoring device under strong wind conditions.

[0072] refer to Figure 4 In some possible implementations, the output end of the control element 300 can extend and retract in the vertical direction, and the output end of the control element 300 is provided with a common section 600, which is connected to the extension 500.

[0073] It is known that the vertical telescopic function of the control component 300 allows the control component 300 to adjust the position of its output end more flexibly, thereby controlling the hook part 200 to meet the anchoring requirements.

[0074] The common section 600 provides a unified connection structure, enabling multiple extensions 500 to achieve synchronous drive through the common section 600, thus simplifying the structural design.

[0075] The extension 500 transmits the movement of the control element 300 from the common section 600 to the connecting rod 400, thereby driving the multiple hook parts 200.

[0076] Specifically, the angle between the hook parts 200 is greater than 90°, therefore the angle between the extension parts 500 on the common section 600 is also greater than 90°.

[0077] The common section 600 transmits the vertical up-and-down movement of the control component 300 to the extension 500, causing the extension 500 to drive the first end of the connecting rod 400 to move.

[0078] The control component 300 is pulled downwards, and since part of the connecting rod 400 is rotatably connected to the housing 100, the connecting rod becomes a lever structure. When the first end of the connecting rod 400 is pressed down, the second end of the connecting rod 400 is tilted upwards, thereby causing the hook part 200 to lift upwards and disengage from the fixing component 01.

[0079] Conversely, when the control component 300 shortens upward, the first end of the connecting rod 400 lifts upward, and the second end of the connecting rod 400 presses downward, thereby causing the hook part 200 to press downward and be fixed after contacting the fixing component 01.

[0080] In this way, the vertical telescopic function of the control component 300 enables the hook part 200 to adapt to changes in the hook angle, improving the flexibility and adaptability of operation; the introduction of the common section 600 simplifies the connection method of multiple extension parts 500, reduces structural complexity, and improves the reliability of the system; the synchronous drive of multiple extension parts 500 is achieved through the common section 600, ensuring the synchronous movement of the hook part 200 and improving the stability of the anchoring device under strong wind conditions.

[0081] It should be noted that the control unit 300 can use a hydraulic cylinder, which uses the pressure of hydraulic fluid to drive the piston to move, thereby realizing the extension and retraction of the output end. The hydraulic cylinder provides powerful force and precise control, making it suitable for heavy-duty and high-precision applications.

[0082] The control unit 300 can also use an electric linear actuator. The electric linear actuator drives a screw or gear mechanism through an electric motor to achieve linear motion. The electric linear actuator is easy to control and integrate, and is suitable for systems that require electrical control.

[0083] The control element 300 can also be a cylinder. The cylinder uses compressed air to drive the piston to move, realizing the extension and retraction of the output end. The cylinder has a fast response and is suitable for light-load and fast-acting applications. As long as the control element 300 can realize the extension and retraction of the output end in the vertical direction, the embodiments of this application do not impose too many restrictions on the type of control element 300.

[0084] In some embodiments, the extension 500 and the common segment 600 are integrally formed. The extension 500 and the common segment 600 are designed as a single structural unit, eliminating the connection interface between components. This integral design improves the strength and rigidity of the structure and reduces loosening or failure that may occur due to connection interfaces.

[0085] When two hook parts 200 are present, the extension part 500 can extend to both sides through the bottom position of the common section 600, and the extension part 500 connects to the two connecting rods 400 respectively. This design ensures that the two hook parts 200 can move synchronously, realize symmetrical anchoring operation, and improve the stability of operation.

[0086] In some possible implementations, the connecting rod 400 has a rotating shaft 410, the connecting rod 400 is rotatably connected to the housing 100 via the rotating shaft 410, the rotating shaft 410 is fixedly connected to the housing 100, and the distance between the first end of the connecting rod 400 and the rotating shaft of the connecting rod 400 is less than or equal to the distance between the second end of the connecting rod 400 and the rotating shaft of the connecting rod 400.

[0087] It is known that the design of the connecting rod 400 enables it to rotate on the fulcrum of the rotating shaft 410, thereby transmitting the motion of the control element 300 to the hook part 200.

[0088] The rotating shaft 410 is fixedly connected to the housing 100 and serves as the fulcrum for the rotation of the connecting rod 400. The rotating shaft 410 provides a fixed axis of rotation, allowing the connecting rod 400 to rotate freely on it, thereby driving the hook part 200.

[0089] The housing 100 provides fixed support for the rotating shaft 410 and provides a structural frame for the entire anchoring device.

[0090] The design of the distance between the first end of the connecting rod 400 and the rotating shaft 410 of the connecting rod 400 and the distance between the second end of the connecting rod 400 and the rotating shaft 410 of the connecting rod 400 enables the connecting rod 400 to generate a larger torque when rotating, thereby improving the operating efficiency and stability of the anchoring device.

[0091] By optimizing the distance relationship between the rotating shaft 410 on the connecting rod 400, a larger torque can be generated on the hook part 200 under the same output force of the control component 300, achieving more efficient anchoring and release operations; the rotation design of the connecting rod 400 ensures the precise movement of the hook part 200, improving the reliability and stability of the anchoring device under strong wind conditions; through reasonable distance design, the dependence on other complex mechanical structures is reduced, improving the reliability of the system.

[0092] In some possible implementations, the connecting rod 400 is provided with an adjustment structure 700.

[0093] The hook part 200 is connected to the second end of the connecting rod 400 via the adjusting structure 700, and the distance between the hook part 200 and the second end of the connecting rod 400 is adjustable.

[0094] It is understood that the connecting rod 400 is connected to the hook part 200 through the adjusting structure 700, which is equivalent to changing the length of the hook part 200, allowing for precise adjustment of the position of the hook part 200, and avoiding the need to replace the entire hook part 200 due to an unsuitable length.

[0095] The introduction of the adjustment structure 700 allows the length of the hook part 200 to be adjusted according to actual needs, adapting to different anchoring requirements and improving operational flexibility. The design of the adjustment structure 700 simplifies the adjustment process of the hook part 200, reduces the complexity of manual operation, and improves operational efficiency.

[0096] refer to Figure 3 In some possible implementations, the adjustment structure 700 includes a first adjustment part 710, which is threadedly connected to the connecting rod 400, and the end of the first adjustment part 710 away from the connecting rod 400 is connected to the hook part 200.

[0097] And / or, the adjustment structure 700 includes a second adjustment part 720, which is threadedly connected to the hook part 200, and the end of the second adjustment part 720 away from the hook part 200 is connected to the connecting rod 400.

[0098] It is known that the first adjustment part 710 is threadedly connected to the connecting rod 400, and the first adjustment part 710 allows the length of the end of the connecting rod 400 near the hook part 200 to be adjusted to adapt to different anchoring requirements.

[0099] Specifically, the first adjustment part 710 and the second adjustment part 720 are adjacent to each other, and the first adjustment part 710 and the second adjustment part 720 are fixedly connected at the junction.

[0100] The second adjustment part 720 is threadedly connected to the hook part 200. The second adjustment part 720 allows the length of the end of the hook part 200 near the connecting rod 400 to be adjusted to meet different anchoring requirements.

[0101] The first adjustment part 710 is threadedly connected to the connecting rod 400 and the second adjustment part 720 is threadedly connected to the hook part 200. The lengths of both the end of the connecting rod 400 near the hook part 200 and the end of the hook part 200 near the connecting rod 400 can be adjusted simultaneously.

[0102] If the threads of the first adjusting part 710, the connecting rod 400, and the hook part 200 of the second adjusting part 720 are in the same direction (e.g., both are right-hand threads), then when the first adjusting part 710 and the second adjusting part 720 are rotated, the length of the connecting rod 400 outside the first adjusting part 710 and the length of the hook part 200 outside the second adjusting part 720 will increase or decrease simultaneously. This design is suitable for situations where it is necessary to increase or decrease the distance between the two ends simultaneously.

[0103] If the threads of the first adjusting part 710 are opposite to those of the connecting rod 400 and the hook part 200 (e.g., one is a right-hand thread and the other is a left-hand thread), then when the first adjusting part 710 and the second adjusting part 720 are rotated, the length of the connecting rod 400 outside the first adjusting part 710 and the hook part 200 becomes longer, and the length outside the second adjusting part 720 becomes shorter; or the length of the connecting rod 400 outside the first adjusting part 710 and the hook part 200 becomes shorter, and the length outside the second adjusting part 720 becomes longer. This design is suitable for situations where it is necessary to simultaneously increase the distance at one end and decrease the distance at the other end.

[0104] Specifically, the first adjustment part 710 and the second adjustment part 720 are rotatably connected.

[0105] The thread direction of the first adjusting part 710 and the connecting rod 400 and the hook part 200 of the second adjusting part 720 can be unrestricted. The first adjusting part 710 and the second adjusting part 720 can be rotated respectively according to the required length of the connecting rod 400 outside the first adjusting part 710 and the length of the hook part 200 outside the second adjusting part 720.

[0106] Through the design of the first adjustment part 710 and the second adjustment part 720, the adjustment structure 700 can flexibly adjust the length of the hook part 200 and thus adjust the position of the hook part 200 to adapt to different anchoring requirements; the dual adjustment method of the adjustment structure 700 (the first adjustment part 710 and the second adjustment part 720) enables the anchoring device to adapt to the dock fixing parts 01 in different positions, improving the adaptability of the system; the threaded connection design simplifies the adjustment process of the hook part 200, reduces the complexity of manual operation, and improves operating efficiency.

[0107] refer to Figure 3 In some embodiments, the adjustment structure 700 further includes a positioning pin 730, which passes through the first adjustment part 710 and / or the second adjustment part 720, and is used to lock the position of the hook part 200 within the first adjustment part 710 and / or the second adjustment part 720.

[0108] Specifically, the locating pin 730 is threadedly connected to the first adjusting part 710 and / or the second adjusting part 720.

[0109] By using the positioning pin 730, the hook part 200 can be prevented from moving within the first adjustment part 710 and / or the second adjustment part 720 after the length of the hook part 200 is adjusted.

[0110] In some possible implementations, housing 100 includes an upper housing 110 and a lower housing 120, which are detachably connected.

[0111] It is known that the housing 100 provides protection and support for the internal components, while its detachable design facilitates maintenance and repair.

[0112] Specifically, the control component 300 passes through the inner cavities of the upper housing 110 and the lower housing 120. The cross-section of the inner cavity of the lower housing 120 gradually increases along the extension and retraction direction of the control component 300. The side of the lower housing 120 has an equipment opening for extending the hook part 200.

[0113] The detachable design of the upper housing 110 and the lower housing 120 eliminates the need to disassemble the entire housing 100 when maintenance or replacement of internal components is required, simplifying the operation process and improving maintenance efficiency. The detachable design allows the housing 100 to adapt more flexibly to different working environments and needs, facilitating adjustments and upgrades to the device. By dividing the housing 100 into the upper housing 110 and the lower housing 120, the assembly and disassembly process of the device is simplified, reducing the complexity of manual operation.

[0114] In practical applications:

[0115] The rotating adjustment structure 700 adjusts the length of the hook part 200 to fit the position of the fixing part 01, and the positioning pin 730 is tightened.

[0116] Initial state: Before the anchoring operation is performed, the control component 300 is in the second state, and the multiple hooks 200 are far apart from each other and are in a state of being detached from the dock fixing component 01.

[0117] Anchoring process initiation: Control unit 300 is activated. The operator activates control unit 300 through the control system, switching it from the second state to the first state, and control unit 300 shortens. The output end of control unit 300 transmits driving force through extension 500, driving connecting rod 400 to rotate within housing 100. The first end of connecting rod 400 lifts upward, and the second end presses downward. The rotation of connecting rod 400 causes hook parts 200 to move closer together, gradually contacting and connecting with the dock fixing member 01 until hook parts 200 are securely connected to fixing member 01.

[0118] Release Anchoring: The operator switches control element 300 back to the second state, and control element 300 extends. Control element 300 drives connecting rod 400 to rotate in the opposite direction via extension 500. This rotation of connecting rod 400 within housing 100 causes the first end of connecting rod 400 to press downwards and the second end to lift upwards. The rotation of connecting rod 400 causes multiple hooks 200 to move away from each other. Hooks 200 disengage from dock fixing element 01, releasing the crane.

[0119] This application provides a crane, including lifting machinery and the above-described anchoring device.
