Description

Technical Field

[0001] This utility model belongs to the technical field of ship loading and unloading platforms, and in particular relates to a water level adaptive steel structure platform for loading and unloading operations of large-tonnage ships. Background Technology

[0002] Ship loading and unloading operations are the process of using tools and machinery to transfer goods from ships to dock yards or in the opposite direction. It involves key links in cargo transportation and mainly uses loading and unloading equipment to unload or load containers, bulk cargo, and other goods from ships. It requires the coordination of mechanical operations to ensure safe and efficient completion. During the operation of ships, there are some temporary loading and unloading platforms for ships to carry out temporary loading and unloading operations.

[0003] Most current temporary loading and unloading platforms are constructed by splicing steel structures. These steel structure platforms are mostly located in water. Since the water level is constantly changing, but the overall height of the steel structure platform is mostly fixed, when the water level is higher than the height of the steel structure platform, the steel structure platform will be submerged in water, making it unusable and reducing the utilization efficiency of the steel structure. To address this, a water level adaptive steel structure platform for loading and unloading operations of large-tonnage ships is provided. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the height of most current steel structure platforms cannot be changed according to water level changes, which easily leads to the steel structure platform becoming unusable after being submerged by water. Therefore, this utility model proposes a water level adaptive steel structure platform for loading and unloading operations of large-tonnage ships.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a water level adaptive steel structure platform for loading and unloading large-tonnage ships, comprising: a supporting steel frame, on the upper surface of which a fixed platform is fixedly installed; a lifting component, disposed on the lower surface of the fixed platform, for adjusting the platform cover according to the water level; and a stabilizing component, disposed on the lower surface of the lifting component, ensuring that the overall center of gravity of the platform remains unchanged while the platform height changes; wherein, the lifting component includes a sealing cover, the upper surface of which is fixedly connected to the lower surface of the fixed platform, and several hydraulic jacks are fixedly installed on the inner wall of the bottom surface of the sealing cover, one end of which extends beyond the upper surface of the fixed platform, the hydraulic jacks enabling the steel structure platform to change height, allowing the steel structure platform to be adjusted short distances according to different water levels.

[0006] As a further description of the above technical solution: A bearing platform is fixedly installed at one end of the hydraulic jack, and a damping shock absorber is fixedly installed on the side wall of the bearing platform. A rubber sleeve is fixedly installed at one end of the damping shock absorber. The rubber sleeve wraps around the damping shock absorber and one side of the bearing platform. The rubber sleeve and the damping shock absorber work together to reduce the impact force generated by the ship on the steel structure platform and improve the protection of the steel structure platform.

[0007] As a further description of the above technical solution: The stabilizing component includes a fixed cylinder, one end of which is connected to the lower surface of the sealing cover. A connecting rod is fixedly installed on the inner wall of the fixed cylinder, and a fixed sleeve is fixedly installed on one end of the connecting rod. The fixed sleeve limits the movement of the threaded column and the ball screw.

[0008] As a further description of the above technical solution: A threaded column is rotatably mounted on the inner wall of the bottom surface of the fixed cylinder. A counterweight is threaded onto the outer surface of the threaded column. The counterweight has a threaded hole inside that matches the threaded column. The threaded column is used to drive the counterweight to move.

[0009] As a further description of the above technical solution: A limiting rod is slidably installed on the inner wall of the counterweight. One end of the limiting rod is fixedly connected to the inner wall of the bottom surface of the fixed cylinder. The limiting rod limits the counterweight and prevents it from rotating with the threaded column, thus preventing it from moving up and down.

[0010] As a further description of the above technical solution: One end of the threaded post extends to the outer surface of the upper surface of the fixed sleeve, and a ball screw is fixedly installed at one end of the threaded post.

[0011] As a further description of the above technical solution: The outer surface of the ball screw is threaded with a screw seat, and the outer surface of the screw seat is fixedly mounted with a lifting sleeve. The upper surface of the lifting sleeve is fixedly connected to the lower surface of the bearing platform. Under the action of the screw seat inside the lifting sleeve, the ball screw converts the linear motion of the lifting sleeve into rotational motion, thereby enabling the ball screw to drive the threaded column to rotate.

[0012] As a further description of the above technical solution: The weight of the counterweight is the same as that of the bearing platform. The counterweight moves inside the fixed cylinder and is used to adjust the overall center of gravity of the steel structure platform, reducing the instability of the steel structure platform caused by changes in the height of the bearing platform.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, by setting up a lifting component, the bearing platform can be height adjusted under the action of hydraulic jacks, realizing that the overall height of the steel structure platform can be adaptively adjusted according to water level changes, further reducing the time the steel structure platform is underwater, ensuring the efficiency of the steel structure platform, reducing the impact on ship loading and unloading operations, and improving the practicality of the steel structure platform. When a ship collides with the steel structure platform, the rubber pad can reduce the damage caused by the steel structure platform to the ship. At the same time, in conjunction with the damping shock absorber, it can also effectively reduce the impact force generated by the ship on the steel structure platform, improving the protection of the steel structure platform itself.

[0014] 2. In this utility model, by setting a stabilizing component, when the bearing platform is adjusted up or down, the counterweight and the bearing platform move in opposite directions with the cooperation of components such as ball screw, lifting sleeve, threaded column and limit rod. This achieves the function of minimizing the change in the center of gravity distance of the steel structure platform after the height of the steel structure platform changes, and further ensures the overall stability of the steel structure platform before and after the height change.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] In specific implementation, such as Figures 1-4 As shown, this utility model provides a technical solution: a water level adaptive steel structure platform for loading and unloading large-tonnage ships, including a supporting steel frame 1, on which a fixed platform 2 is fixedly installed; a lifting component 3, disposed on the lower surface of the fixed platform 2, for adjusting the platform cover according to the water level; and a stabilizing component 4, disposed on the lower surface of the lifting component 3, ensuring that the overall center of gravity of the platform remains unchanged while the platform height changes; wherein, the lifting component 3 includes a sealing cover 32, the... The upper surface of the sealing cover 32 is fixedly connected to the lower surface of the fixed platform 2. Several hydraulic jacks 35 are fixedly installed on the inner wall of the bottom surface of the sealing cover 32. One end of each hydraulic jack 35 extends to the outside of the upper surface of the fixed platform 2. A bearing platform 31 is fixedly installed on one end of each hydraulic jack 35. A damping shock absorber 33 is fixedly installed on the side wall of the bearing platform 31. A rubber sleeve 34 is fixedly installed on one end of each damping shock absorber 33. The rubber sleeve 34 wraps around one side of the damping shock absorber 33 and the bearing platform 31.

[0022] When the steel structure platform is in use, the height of the bearing platform 31 can be adjusted upwards or downwards according to the changes in water level, under the action of several hydraulic jacks 35, so that the bearing platform 31 and the water level are in a suitable position. When the ship approaches the bearing platform 31, the outer surface of the ship collides with the rubber sleeve 34. At this time, the damping shock absorber 33 and the rubber sleeve 34 work together to buffer the impact force generated by the ship on the bearing platform 31. Then, after the ship is docked and stabilized, loading and unloading can be carried out. This realizes the function of the bearing platform 31 to adaptively adjust according to the water level. At the same time, the rubber sleeve 34 and the damping shock absorber 33 can reduce the impact force generated by the ship on the steel structure platform and improve the protection of the steel structure platform.

[0023] like Figures 3-4As shown, the stabilizing component 4 includes a fixed cylinder 41, one end of which communicates with the lower surface of the sealing cover 32. A connecting rod 48 is fixedly installed on the inner wall of the fixed cylinder 41, and a fixed sleeve 47 is fixedly installed on one end of the connecting rod 48. A threaded post 42 is rotatably installed on the inner wall of the bottom surface of the fixed cylinder 41. A counterweight 46 is threadedly installed on the outer surface of the threaded post 42. The counterweight 46 has a threaded hole inside that matches the threaded post 42. A limit rod 43 is slidably installed on the inner wall of the counterweight 46. One end of the limiting rod 43 is fixedly connected to the inner wall of the bottom surface of the fixed cylinder 41. One end of the threaded column 42 extends to the outer surface of the upper surface of the fixed sleeve 47. A ball screw 44 is fixedly installed at one end of the threaded column 42. A screw seat is threaded on the outer surface of the ball screw 44. A lifting sleeve 45 is fixedly installed on the outer surface of the screw seat. The upper surface of the lifting sleeve 45 is fixedly connected to the lower surface of the bearing platform 31. The weight of the counterweight 46 is the same as the weight of the bearing platform 31. The counterweight 46 is displaced inside the fixed cylinder 41.

[0024] During the upward or downward movement of the bearing platform 31, the bearing platform 31 will drive the lifting sleeve 45 to move synchronously. At this time, the lifting sleeve 45 will drive the screw seat to move on the outer surface of the ball screw 44. Under the action of the thread, the linear motion of the lifting sleeve 45 is converted into the rotational motion of the ball screw 44, thereby causing the ball screw 44 to rotate. At this time, the ball screw 44 will drive the threaded column 42 to rotate under the limit of the fixed sleeve 47. As the threaded column 42 rotates, under the action of the threaded hole, the counterweight 46 moves upward or downward in the fixed cylinder 41 under the limit of the limit rod 43. When the bearing platform 31 moves upward, the counterweight 46 will move towards the bottom of the fixed cylinder 41. Conversely, when the bearing platform 31 moves downward, the counterweight 46 will move towards the top of the fixed cylinder 41. The weight of the counterweight 46 is the same as that of the bearing platform 31. Therefore, when the two move in opposite directions, the overall center of gravity of the steel structure platform does not change, thus ensuring the stability of the steel structure platform.

[0025] Working Principle: During use, the steel structure platform can adjust the height of the bearing platform 31 upwards or downwards according to water level changes, using several hydraulic jacks 35. This ensures the bearing platform 31 is in a suitable position relative to the water level. During the upward or downward movement of the bearing platform 31, the lifting sleeve 45 moves synchronously. The lifting sleeve 45 then moves the screw seat on the outer surface of the ball screw 44. Under the action of the thread, the linear motion of the lifting sleeve 45 is converted into the rotational motion of the ball screw 44, causing it to rotate. This rotation of the ball screw 44 then drives the threaded column 42 to a fixed position. Under the limit of sleeve 47, the counterweight 46 rotates. As the threaded column 42 rotates, under the action of the threaded hole, the counterweight 46 moves up or down in the fixed cylinder 41 under the limit of the limit rod 43. When the bearing platform 31 moves upward, the counterweight 46 moves to the bottom of the fixed cylinder 41. Conversely, when the bearing platform 31 moves downward, the counterweight 46 moves to the top of the fixed cylinder 41. When the ship approaches the bearing platform 31, the outer surface of the ship collides with the rubber sleeve 34. At this time, the damping shock absorber 33 and the rubber sleeve 34 cooperate to buffer the impact force generated by the ship on the bearing platform 31. Then, after the ship is docked and stabilized, the loading and unloading can be carried out.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
