Description

Technical Field

[0001] This utility model belongs to the technical field of gantry cranes, and in particular relates to a shipbuilding gantry crane. Background Technology

[0002] A shipbuilding gantry crane is a large lifting device specifically designed for the shipbuilding industry. It typically consists of gantry legs, a main beam, a trolley traveling mechanism, and a lifting system. Its core function is to achieve precise high-altitude lifting and relocation of hull sections and large components. Due to its large span and high lifting height, the crane must adapt to the dynamic operational needs of the complex environment of a shipyard.

[0003] Traditional shipbuilding gantry cranes face the following key problems in lifting operations: insufficient stability of cargo under gusts of wind. If a sudden gust of wind occurs during the lifting process, the cargo (such as ship sections) is prone to large swings due to the lack of dynamic fixing devices, which leads to a decrease in positioning accuracy and may even cause collision accidents. Existing technologies mostly rely on reinforcing the overall structure of the crane (such as adding counterweights) or anchoring it when stopped, which cannot suppress cargo swaying in real time during operation, seriously affecting work efficiency.

[0004] To address these issues, we provide a shipbuilding gantry crane. Utility Model Content

[0005] The purpose of this utility model is to provide a shipbuilding gantry crane that, through the cooperation of stabilizing components and anti-sway components, solves the problem of insufficient cargo stability and inability to suppress cargo swaying in real time during operation in existing gantry cranes under gust wind conditions, which seriously affects work efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a shipbuilding gantry crane, comprising outriggers, a main beam fixedly connected to the top of the outriggers, a trolley travel box slidably connected to the top of the main beam, a wire rope wound inside the trolley travel box, a hook fixedly connected to the bottom of the wire rope, a stabilizing component provided on one side of the main beam, the stabilizing component including a stabilizing rod provided on one side of the main beam, a stabilizing block slidably connected to the surface of the stabilizing rod, an extension block fixedly connected to one side of the stabilizing block, and an electromagnetic plate provided at the bottom of the extension block, and an anti-sway component provided at the bottom of the main beam, the anti-sway component including a vertical plate fixedly connected to the bottom of the stabilizing block, an anti-sway plate provided on one side of the vertical plate, and an anti-sway groove formed on one side of the anti-sway plate.

[0008] The present invention is further configured such that there are two stabilizing components, with the two sets of stabilizing components located on the front and rear sides of the main beam, respectively.

[0009] The present invention is further configured such that the three stabilizing rods are arranged in a group inside the stabilizing block, and the three stabilizing rods are arranged in a triangle. A stabilizing groove is provided inside the stabilizing block, and the stabilizing rods are located inside the stabilizing groove.

[0010] The present invention is further configured such that a first hydraulic cylinder is fixedly connected to the top of the extension block, the output end of the first hydraulic cylinder extends to the bottom of the extension block, and the output end of the first hydraulic cylinder is movably connected to the electromagnetic plate through a rotating shaft.

[0011] The present invention is further configured such that there are four electromagnetic plates, and connecting rods are fixedly connected to both sides of the trolley running box, with the other end of the connecting rods fixedly connected to the stabilizing block.

[0012] The present invention is further configured such that a second hydraulic cylinder is fixedly connected to the rear side of the vertical plate, the output end of the second hydraulic cylinder extends to the front side of the vertical plate, and the output end of the second hydraulic cylinder is fixedly connected to the anti-sway plate.

[0013] The present invention is further configured such that the anti-sway plate is U-shaped, the anti-sway groove is formed on the side of the anti-sway plate near the steel wire rope, and a rubber pad is fixedly connected inside the anti-sway groove.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model effectively suppresses the swaying of goods in gusts of wind through the synergistic effect of triangular stabilizing rods and electromagnetic plates. The three stabilizing rods arranged in a triangular pattern in the stabilizing component work in conjunction with the electromagnetic plate to fix the goods within 0.5 seconds, reducing the swaying amplitude. At the same time, the C-shaped anti-sway plate and the rubber pad dynamically wrap the steel wire rope in the anti-sway component, and are precisely limited by hydraulic drive, forming a dual anti-sway mechanism of "goods-steel wire rope".

[0016] 2. This invention breaks through efficiency bottlenecks through a real-time response system. The stabilizing and anti-sway components are linked by hydraulic drive and intelligent control, and can be automatically activated when triggered by gusts of wind, without interrupting the hoisting process. It is especially suitable for coastal environments with high wind frequencies.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0025] Please see Figures 1-4 This utility model relates to a shipbuilding gantry crane, comprising outriggers 1, a main beam 2 fixedly connected to the top of the outriggers 1, a trolley travel box 3 slidably connected to the top of the main beam 2, a wire rope 4 wound inside the trolley travel box 3, a hook 5 fixedly connected to the bottom of the wire rope 4, and a stabilizing component on one side of the main beam 2. The stabilizing component includes a stabilizing rod 6 on one side of the main beam 2, a stabilizing block 7 slidably connected to the surface of the stabilizing rod 6, an extension block 8 fixedly connected to one side of the stabilizing block 7, and an electromagnetic plate 9 at the bottom of the extension block 8. Through the stabilizing component, the stabilizing block 7 slides along the stabilizing rod 6 and is linked with the trolley travel box 3 through a connecting rod 14, ensuring that the stabilizing component moves synchronously with the lifting point during the lifting process. To maintain dynamic balance, the four electromagnetic plates 9 at the bottom of the extension block 8 are driven by the first hydraulic cylinder 13, which can quickly press down onto the surface of the goods and be energized to attract them. The goods are fixed within 0.5 seconds after a gust of wind is triggered, reducing the swing amplitude. The bottom of the main beam 2 is equipped with an anti-sway component, which includes a vertical plate 10 fixedly connected to the bottom of the stabilizing block 7, an anti-sway plate 11 set on one side of the vertical plate 10, and an anti-sway groove 12 opened on one side of the anti-sway plate 11. With the anti-sway component, the anti-sway plate 11 has an anti-sway groove 12 on the side near the steel wire rope 4. The second hydraulic cylinder 15 pushes the anti-sway plate 11 to move, so that the steel wire rope 4 is embedded in the groove. The friction damping of the rubber pad suppresses the lateral swing. Example

[0026] Please see Figures 1-4Based on Example 1, two stabilizing components are used, located on the front and rear sides of the main beam 2 respectively. These two sets of stabilizing components stabilize the front and rear sides of the hoisted workpiece. Three stabilizing rods 6 are arranged in a triangular formation inside the stabilizing block 7. A stabilizing groove is provided inside the stabilizing block 7, and the stabilizing rods 6 are located within this groove. The triangular arrangement of the stabilizing rods 6 enhances their support strength and improves the stability of the stabilizing block 7 during movement. A first hydraulic cylinder 13 is fixedly connected to the top of the extension block 8, with its output end extending to the bottom of the extension block 8. The output end of the first hydraulic cylinder 13 is movably connected to an electromagnetic plate 9 via a rotating shaft. The first hydraulic cylinder 13 is used to push the electromagnetic plate 9 up and down. There are four electromagnetic plates 9. Connecting rods 14 are fixedly connected to both sides of the trolley running box 3. The other end of the connecting rod 14 is fixedly connected to the stabilizing block 7. The connecting rods 14 are used to fix the trolley running box 3 and the stabilizing block 7. When the trolley running box 3 moves, the stabilizing block 7 moves synchronously. A second hydraulic cylinder 15 is fixedly connected to the rear side of the vertical plate 10. The output end of the second hydraulic cylinder 15 extends to the front side of the vertical plate 10. The output end of the second hydraulic cylinder 15 is fixedly connected to the anti-sway plate 11. The second hydraulic cylinder 15 is used to push the anti-sway plate 11 to move towards the wire rope 4. The anti-sway plate 11 is U-shaped. The anti-sway groove 12 is opened on the side of the anti-sway plate 11 near the wire rope 4. A rubber pad is fixedly connected inside the anti-sway groove 12. The wire rope 4 enters the anti-sway groove 12 to reduce the swaying amplitude of the wire rope 4.

[0027] The working principle of this utility model is as follows: the trolley travel box 3 lowers the hook 5, the hook 5 lifts the goods, and during the lifting process, the control system of the gantry crane is connected to the weather monitoring system of the construction area. When the weather monitoring system detects gusts of wind around the construction area, the control system promptly triggers the stabilization component and the anti-sway component.

[0028] The first hydraulic cylinder 13 drives the electromagnetic plate 9 to move downward, so that the bottom of the electromagnetic plate 9 contacts the object being hoisted. Since the electromagnetic plate 9 is designed with a rotating shaft, it can be attached to the top of the object being hoisted. When the electromagnet is energized, it magnetically attracts the cargo. The cargo is fixed by the magnetic attraction of the four electromagnetic plates 9, which reduces the swaying amplitude of the cargo when gusts of wind blow.

[0029] The second hydraulic cylinder 15 drives the anti-sway plate 11 to move towards the wire rope 4, so that the wire rope 4 enters the anti-sway groove 12. The anti-sway plate 11 can limit the wire rope 4 and reduce the sway amplitude of the wire rope 4, thereby reducing the sway amplitude of the hoisted object. After the gust of wind passes, the first hydraulic cylinder 13 and the second hydraulic cylinder 15 reset, and the hoisting work can be carried out again.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
