Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, specifically to an assembly platform for installing large ship components. Background Technology

[0002] A ship is a man-made means of transportation that primarily operates in water. Civilian ships are generally called boats, military ships are called warships, and small boats are called vessels or dinghies; collectively, they are called ships or dinghies. Internally, they mainly include interior space, supporting structures, and drainage structures, and have a propulsion system that utilizes external or internal energy. Externally, they are generally streamlined envelopes that help overcome fluid resistance. Materials are constantly updated with technological advancements; early materials included natural materials such as wood, bamboo, and hemp, while modern materials are mostly steel, aluminum, fiberglass, acrylic, and various composite materials. In current shipbuilding processes, the stern propeller and rudder are mostly positioned and installed using a gantry crane, with manual or pneumatic hoists used to pull the propeller or rudder. This method is labor-intensive, time-consuming with cranes, has low positioning accuracy, and low work efficiency, and can no longer meet the industry's requirements for improving shipbuilding efficiency, shortening the shipbuilding cycle, and increasing shipbuilding precision. However, existing ship installation platforms have poor top protection and cause strong visual fear among workers; the hydraulic system of the installation platform has an externally mounted cable encoder, which is prone to damage or wire breakage; the hydraulic cylinder of the hydraulic system is set up separately, which has the problem of radial sway; during the movement of the installation platform, there is no safety sensing device, and it cannot stop or alarm in time when there are obstacles.

[0032] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Specific implementation method one: See Figures 1-10This embodiment describes a specific assembly platform for installing large ship components. The platform includes a platform trolley, a rudder mounting bracket, and a propeller mounting bracket. The rudder mounting bracket and propeller mounting bracket are installed sequentially on the platform trolley according to the ship component installation sequence for assembly. The platform trolley includes a base and four sets of main lifting cylinder systems 1. The main lifting cylinder systems 1 are installed at the four corners of the base, and wheel structures are provided at the bottom of each system. When rudder blades need to be installed, the rudder mounting bracket is installed on the base of the platform trolley. When propeller blades need to be installed, the rudder mounting bracket is removed from the platform trolley, and the propeller mounting bracket is installed on the base of the platform trolley.

[0034] The rudder mounting frame includes a main body, several rudder lifting cylinders 2, and two sets of rudder mounting platform guardrails 4. The rudder lifting cylinders 2 are located inside the main body of the rudder mounting frame. The main body of the rudder mounting frame is a telescopic frame structure. The lower end of the rudder lifting cylinder 2 is connected to the bottom of the main body of the rudder mounting frame, and the top end of the rudder lifting cylinder 2 is connected to the upper part of the main body of the rudder mounting frame. The rudder lifting cylinders 2 drive the upper part of the main body of the rudder mounting frame to rise and fall. The rudder mounting platform guardrails 4 are symmetrically arranged on the top of the main body of the rudder mounting frame.

[0035] The propeller mounting frame includes a main body, several propeller assembly platform lifting cylinders 5, and a propeller assembly platform guardrail 6. The propeller assembly platform lifting cylinders 5 are located inside the main body of the propeller mounting frame and drive the upper part of the main body of the propeller mounting frame to rise and fall. The propeller assembly platform guardrail 6 is located on the top of the main body of the propeller mounting frame.

[0036] The platform trolley main lifting cylinder system 1 includes an outer cylinder 7, an inner cylinder 8, and a hydraulic cylinder 9. The bottom of the inner cylinder 8 is equipped with a wheel structure, the outer cylinder 7 is fitted on the outside, and the hydraulic cylinder 9 is installed inside. The lower end of the hydraulic cylinder 9 is bolted to the bottom of the inner cylinder 8 through a connecting flange 14, and the upper flange is connected to the top of the outer cylinder 7. The outer cylinder is connected to the base, and a ram structure is provided between the outer cylinder 7 and the inner cylinder 8.

[0037] The slide structure includes several outer cylinder guide slides 10 and several inner cylinder guide slides 11. Two outer cylinder guide slides 10 are provided on each inner wall of the outer cylinder 7, and the outer cylinder guide slides 10 are fixed to the inner wall of the outer cylinder 7 by bolts. A guide groove 12 is formed between the two outer cylinder guide slides 10. One inner cylinder guide slide 11 is provided on each outer wall of the outer cylinder 7, and the inner cylinder guide slide 11 is embedded in the guide groove 12. The slide structure can effectively limit the stroke direction of the hydraulic cylinder 9, reduce the radial swing of the hydraulic cylinder 9, make the platform lifting process more stable, have better straightness, and will not produce side tilting or other problems.

[0038] The hydraulic cylinder 9 is equipped with an encoder. By embedding the encoder in the hydraulic cylinder 9, the problem of damage or breakage of external wire encoders can be avoided during use. It is also not affected by sea winds or other factors that could cause inaccuracy. Furthermore, it enables precise position control in the control system with an accuracy value of ≤1mm.

[0039] The rudder mounting platform guardrail 4 and propeller assembly platform guardrail 6 are equipped with several perforated plates 13.

The perforated plates 13 are 1300mm high. Perforated plates are not installed at the handrail positions of the guardrails to avoid the edges of the perforated plates 13 scratching workers.

[0040] The platform trolley, rudder mounting bracket, and propeller mounting bracket are equipped with obstacle avoidance sensors at the center, high, and low positions around their perimeter. The control system can effectively ensure that when the obstacle avoidance sensors detect obstacles during the vehicle's movement, the vehicle will stop in time within a safe distance. This installation effectively avoids safety accidents, especially ensuring the safety of personnel. The obstacle avoidance sensors can be infrared or lidar type.

[0041] In summary, the assembly platform for installing large ship components described in this utility model reduces visual dizziness caused by installing perforated plates 13 on the guardrail, while also reducing the possibility of objects falling from heights. By embedding the pull-rope encoder inside the hydraulic cylinder 9, the encoder is protected from environmental influences, avoiding inaccurate accuracy issues and the problems of easy damage and breakage of pull-rope encoders. The assembly platform for installing large ship components described in this utility model also features a sliding ram structure between the inner cylinder 8 and outer cylinder 7 of the hydraulic system, limiting the sliding between them and reducing the radial sway of the hydraulic cylinder 9. This ensures a smoother platform lifting process with better straightness and prevents lateral tilting. Furthermore, the assembly platform for installing large ship components described in this utility model incorporates obstacle avoidance sensors around the platform. The control system effectively ensures that when obstacles are detected by the sensors during vehicle movement, the platform stops promptly within a safe distance, thus effectively preventing accidents and ensuring personnel safety.
