Description

Technical Field

[0001] This utility model relates to ship equipment installation structures, specifically to a bracket for temporary fixing and support of ship equipment during ship construction and equipment installation. Background Technology

[0002] In shipbuilding and equipment loading operations, temporary supports are core components that support equipment such as power units and navigation radars. However, existing technologies have significant defects and are difficult to adapt to the industry's demand for high efficiency and low cost.

[0003] First, the reuse rate is extremely low. Most of the current mainstream brackets are disposable structures welded on-site. After the equipment is installed, they need to be cut and dismantled. A single 10,000 TEU container ship can scrap 5-8 tons of steel. In addition, the weld marks need to be ground and repaired for corrosion protection. The processing time for a single ship exceeds 30 hours. Dozens of specifications also need to be customized to adapt to different equipment, resulting in high inventory and recycling costs.

[0004] Secondly, the lack of shock absorption and protection results in inadequate equipment protection. During loading, the impact of hoisting can easily scratch equipment or displace precision components; during sea trials, hull vibrations of 2-8Hz are directly transmitted through rigid supports, causing loosening of equipment bolts and drift in instrument accuracy (such as increased pointing error in navigation radar). A few supports with spring-loaded cushioning can only withstand small vertical impacts, with a vibration attenuation rate ≤40%, which fails to meet the vibration control standards for precision equipment.

[0005] Finally, they suffer from insufficient adaptability and stability, resulting in low efficiency. Traditional supports need to be designed individually for each piece of equipment, leading to frequent replacements and work interruptions; they also rely on welding skills, and welding defects can easily cause the supports to tilt; lacking a precise positioning structure, the installation of a single set takes more than 2 hours, hindering the efficiency of loading onto ships. Summary of the Invention

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a temporary support for ship loading and fixing with a multi-level buffer and shock-resistant structure. This support has good versatility, strong buffer and shock absorption performance, is easy to install and disassemble and has a high reusability.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] This utility model discloses a temporary support frame for ship loading and fixing with a multi-level buffer and seismic resistance structure, comprising: multiple support units with identical structures and spaced apart front and rear, each support unit comprising:

[0009] H-beam embedded parts, wherein the H-beam embedded parts are welded to the hull;

[0010] The upper base is fixedly connected to the H-beam steel embedded part;

[0011] An upper buffer device, comprising an upper metal housing, which is welded and fixed to an upper base, and an upper spring installed inside the upper metal housing, the upper end of which is fixed to the inner top wall of the upper metal housing;

[0012] The adjustment unit includes an adjustable threaded rod, the upper side of which is fixedly connected to an upper spring. An adjustable threaded sleeve is threadedly connected to the adjustable threaded rod, and an upper flange is fixed to the bottom of the adjustable threaded sleeve.

[0013] The lower buffer device includes a lower metal shell, the top wall of which is welded and fixed to the bottom wall of the lower flange, the upper flange and the lower flange are fixedly connected to form a lower base, and a lower spring is installed inside the lower metal shell, the upper end of which is fixed to the inner top wall of the lower metal shell.

[0014] The fine-tuning unit includes a fine-tuning threaded rod, the upper side of which is fixedly connected to a lower spring. A fine-tuning threaded sleeve is threadedly connected to the adjustable threaded rod, and the bottom of the fine-tuning threaded sleeve is fixedly connected to the upper half ring of a replaceable clamp.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model is used to adapt to the installation and fixing of pipelines of different heights and diameters on ships. By setting corresponding support units, it can flexibly adapt to various types of pipelines and has strong versatility. The buffer component effectively improves the buffering and shock absorption performance, copes with the vibration of ship operation and the impact of pipeline installation, and protects the pipeline and support structure.

[0020] H-beam embedded part 1, wherein the H-beam embedded part is welded to the hull;

[0021] The upper base 2 is fixedly connected to the H-beam steel embedded part 1. Preferably, the upper base and the embedded part are fixedly connected by bolts. The H-beam steel embedded part and the upper base are made of heavy metal materials. The H-beam steel embedded part is used to provide the top support foundation for the bracket, and the upper base serves as the bottom foundation component of the bracket, supporting the entire bracket and pipeline.

[0022] The upper buffer device 3 includes an upper metal shell, which is welded and fixed to the upper base. An upper spring is installed inside the upper metal shell, and the upper end of the upper spring is fixed to the inner top wall of the upper metal shell.
