Description

Technical Field

[0001] This utility model belongs to the field of port and dock equipment, specifically a windproof anchoring structure for cranes. Background Technology

[0002] Cranes, as core equipment in ports, docks, and large industrial settings, are widely used for loading, unloading, handling, and stacking heavy objects. Their performance and safety directly affect logistics efficiency and the stability of on-site operations. In daily operation, cranes typically rely on rails to move along the dock or site area to complete tasks. However, when cranes are stationary, especially under adverse weather conditions such as strong winds, storms, or typhoons, they are prone to slippage, displacement, or even tipping due to horizontal wind forces. Because cranes are large, relatively lightweight, and have a tall structure, the risk of slippage or tipping is extremely high when subjected to strong winds, easily leading to equipment damage, cargo loss, or even threatening personnel safety. Therefore, to ensure the stability of cranes when stationary, equipping them with efficient and reliable wind-resistant anchoring devices has become a crucial technical aspect in crane design and application.

[0003] Traditional wind-resistant anchoring methods typically involve pre-installing anchor seats near the dock tracks. These seats are fixed to the ground via embedded concrete foundations or steel structures. When the crane stops, anchor pins are inserted into the holes of the anchor seats to limit its movement. This method can, to some extent, resist the thrust of wind on the crane, thus preventing slippage accidents. However, this design has several significant drawbacks: First, the installation of anchor seats requires advance planning and design during dock construction, and must be pre-installed or reinforced in conjunction with the overall project. This not only increases the complexity and cost of the project but also places high demands on design and construction precision. Second, in existing docks or facilities, if additional anchor seats are required, large-scale modifications to the existing infrastructure are necessary, potentially involving costly projects such as track adjustments and foundation reconstruction, significantly impacting construction progress and operation. Third, due to the fixed nature of the anchor seats, the crane must be parked in a pre-set, fixed position, making it difficult to flexibly adjust the stopping position or adapt to different working conditions, thus limiting its usability. Utility Model Content

[0004] To address the problems of traditional windproof anchoring schemes being complex to construct, costly, and lacking flexibility, making it difficult to meet the diverse operating needs of modern cranes, this utility model provides a windproof anchoring structure for cranes.

[0005] This utility model is achieved through the following technical solution:

[0006] A crane windproof anchoring structure includes an anchoring frame, an anchoring insert, an anchoring plate, and a rail; the upper part of the anchoring frame is connected to the crane; the rail is a base mounting surface for mounting the anchoring plate; the anchoring plate is provided with anchoring holes; the anchoring insert is installed on the lower part of the anchoring frame and moves up and down relative to the anchoring frame to insert into the anchoring holes to restrict the horizontal movement of the crane.

[0007] A further improvement of this utility model is that the anchoring frame is welded to the crane.

[0008] A further improvement of this utility model is that the anchoring plate is provided in multiple sets, and each set is provided with two anchoring plates.

[0009] A further improvement of this utility model is that the anchor plate is provided with multiple bolt holes, and the multiple bolt holes are on the same horizontal line; the bolt holes are provided with anchor bolts to fix the anchor plate to the track.

[0010] A further improvement of this utility model is that it also includes a limit switch, which is disposed on the anchoring frame and used to detect the state of the anchoring insert and the anchoring plate.

[0011] A further improvement of this utility model is that it also includes a hook, which is disposed on the anchoring frame, and the anchoring plate moves upward and is fixed to the anchoring frame by the hook.

[0012] As can be seen from the above technical solution, the beneficial effects of this utility model are: This structure, by setting a vertically movable anchor plate within the anchor frame, in conjunction with the anchor plate and anchor holes on the track, achieves efficient wind-resistant limiting of the crane when it is stopped. It also features high flexibility, low construction cost, and high safety. Compared to traditional fixed anchor seats, this structure does not rely on complex infrastructure modifications, is suitable for various working conditions, and further enhances operational safety and convenience through limit switches and hook devices, significantly improving the stability and efficiency of the crane under adverse weather conditions.

[0018] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0019] like Figure 1-3 As shown, this utility model discloses a windproof anchoring structure for a crane, including an anchoring frame 1, an anchoring insert 2, an anchoring plate 3, and a track 8. The upper part of the anchoring frame 1 is connected to the crane to support the entire anchoring system and provide displacement for the anchoring insert 2. To ensure the stability of the anchoring frame 1, it is connected to the crane by welding in this embodiment. In use, the anchoring insert 2 moves up and down via a hydraulic cylinder, an electric drive device, or a manual rope pull device. The hydraulic cylinder or electric drive device is installed on the upper part, side, or other position of the anchoring frame 1 that does not affect its function. The manual rope pull device is a backup solution, which can be used to manually move the insert plate up and down in special circumstances. The track 8 serves as the base mounting surface for installing the anchoring plate 3 to ensure the stability and anti-slip capability of the anchoring system. The anchoring plate 3 is provided with anchoring holes 4, which cooperate with the insertion part of the anchoring insert 2 to limit the horizontal slippage of the crane when the anchoring insert 2 is lowered into place. Anchor plate 2 is installed at the lower part of anchor frame 1 and moves up and down relative to anchor frame 1 via a slide rail. When inserted into anchor hole 4, it limits the movement of the crane. When the crane stops, the drive device lowers anchor plate 2 into anchor hole 4, fixing the crane in place through the limiting function of anchor plate 3. When the crane starts running, anchor plate 2 is pulled up to a predetermined position, disengaging from anchor hole 4, thus releasing the limiting function. This structure effectively limits horizontal slippage when the crane stops, ensuring the stability and safety of the crane, while releasing the limiting function during operation to ensure normal operation.

[0020] Multiple sets of anchor plates 3 are provided, with two anchor plates 3 in each set. These two anchor plates 3 are arranged parallel to each other on both sides of the track 8 to improve the stability and anti-slip capability of the anchoring system. During the lowering of the anchor plates 2, the two anchor plates 3 are simultaneously inserted into the corresponding anchor holes 4 on the track 8, forming multi-point support and ensuring the stability of the anchoring system. The parallel arrangement of the anchor plates 3 also disperses the force, enhancing wind and anti-slip capabilities, making it particularly suitable for strong winds and complex operating environments. Multiple bolt holes are also provided on the anchor plates 3, all on the same horizontal line for easy installation and fixing. Anchor bolts 5 are installed in the bolt holes to fix the anchor plates 3 to the track 8, thus forming a stable anchoring foundation. During installation, the anchor plates 3 are tightened to the track 8 by passing the anchor bolts 5 through the bolt holes, ensuring the stability of the anchor plates 3. By using multiple fixing points, the anchor plate 3 is prevented from loosening or shifting during long-term use, ensuring the reliability of the anchoring device. The anchor plate 3 in this structure is innovatively designed, unlike traditional independent anchor plates. It combines the function of a track clamping plate, achieving a dual function of anchoring and track fixing after modification. Specifically, the anchor plate 3 not only retains the function of the traditional track clamping plate for fixing the track, but also adds anchoring holes 4, allowing it to work with the anchoring insert 2 when the crane is stopped, forming a reliable limiting structure. The anchor plate 3 is used to fix the track 8, firmly fixing it to the foundation through multiple bolt holes and anchoring bolts 5. The added anchoring holes 4 provide additional anchoring and limiting function under wind force. Furthermore, the anchor plate 3 can directly replace the existing track clamping plate, eliminating the need for large-scale construction of the dock or track infrastructure, facilitating installation and maintenance, and is suitable for new or renovated sites.

[0021] The system also includes a limit switch 6, which monitors the status of the anchoring plate 2 in real time to ensure the safety and reliability of the anchoring system during operation or shutdown. In this embodiment, the limit switch 6 is equipped with a photoelectric sensor or proximity sensor to detect the positioning status of the anchoring plate 2. The limit switch 6 is equipped with a signal output port, which is connected to the crane's control system via a cable or wireless module to achieve real-time transmission of status signals. When the anchoring plate 2 is lowered into the anchoring hole 4, the limit switch 6 immediately sends a "lock" signal to the crane control system, indicating that the anchoring plate 2 is fully in place, the crane is locked, and operation cannot begin. Conversely, when the anchoring plate 2 is pulled up and disengaged from the anchoring hole 4, the limit switch 6 triggers an "unlock" signal, allowing the crane to resume operation. Through signal detection by the limit switch 6, the anchoring system is safely locked when the crane is stopped and can be quickly unlocked when the crane is running, avoiding the risks caused by misoperation.

[0022] Hook 7 is installed on anchor frame 1 and is used to fix anchor plate 2 to anchor frame 1 when it is pulled up to a predetermined position. When the crane is running, after anchor plate 2 is pulled up by the drive device, it is mechanically fixed to anchor frame 1 by hook 7, thereby ensuring that anchor plate 2 is in a safe position. The function of hook 7 is to prevent anchor plate 2 from sliding down unexpectedly due to external force or mechanical vibration during operation, and further ensure the safety of operation.

[0023] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
