Description

Technical Field

[0001] This utility model relates to the technical field of port transportation and loading equipment for dry bulk cargo such as coal, and in particular to a rotary drag chain device for a ship loader chute. Background Technology

[0002] Qinhuangdao Port Coal Phase V Terminal, as a professional coal transportation terminal, is equipped with four ship loaders with a rated loading efficiency of 8000t / h. All four ship loaders are equipped with a chute loading mechanism, which consists of an eight-sided bucket, a chute platform, a slewing bearing, a chute, and a large shovel from top to bottom. The chute unloading mechanism of the ship loader is an important component, and its main function is to allow coal conveyed by the boom belt to enter the ship's hold and to achieve uniform loading of coal into all corners of the hold. As downstream equipment in the port's loading and unloading process, the ship loader is a very important link in the port's equipment. The continuous improvement of its operating capacity directly and greatly improves the port's loading efficiency.

[0003] With increasing environmental awareness, pollutant control during dry bulk cargo loading and unloading is receiving more and more attention. The mist cannons and sprinkler systems installed on ship loader chutes are commonly used environmental protection equipment, and ensuring their normal operation is a primary task. The environment of the pipelines in the ship loader chute is quite harsh. The chute houses mist cannons, mist cannon pipelines, sprinkler frames, sprinkler pipelines, shovel cylinders, hydraulic lines, and power cables. All components on the chute rotate synchronously with it. During rotation, the pipelines rub and scrape against the chute. In strong winds, they can become entangled in the mist cannons and sprinkler frames, causing pipeline breakage and equipment failure. Existing technology adds protective sleeves to the pipelines to enhance their wear resistance and tensile strength, reducing damage caused by direct friction and scraping between the pipelines and the chute and other components. However, as the chute rotates synchronously with the equipment, the protective sleeves continuously rub against the chute body, mist cannon supports, and other components. Even with wear-resistant materials, the surface of the protective sleeves will wear and crack quickly, requiring periodic disassembly and replacement, increasing operating costs. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a rotary cable chain device for a ship loader chute, aiming to improve the problem in the prior art where, when the chute rotates synchronously with the equipment, the protective sleeve continuously rubs against the chute body, mist cannon support, and other components. Even with wear-resistant materials, the surface of the protective sleeve will wear and crack quickly, requiring regular disassembly and replacement, increasing operating costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ship loader chute rotary drag chain device, comprising a chute platform, an outer frame of a drag chain mechanism installed inside the chute platform, an inner frame of a drag chain mechanism installed inside the outer frame of the drag chain mechanism, a chain body installed inside the inner frame of the drag chain mechanism, and an inner ring stop installed inside the chain body.

[0006] Furthermore, a cylinder is installed at the bottom of the chute platform, and the bottom of the outer wall of the inner frame of the cable chain mechanism is fixedly connected to the top of the outer wall of the cylinder.

[0007] Furthermore, the bottom of the outer wall of the outer frame of the cable chain mechanism is fixedly connected to the inner wall of the middle part of the chute platform, and the inner wall of the outer frame of the cable chain mechanism is rotatably connected to the outer wall of the inner frame of the cable chain mechanism.

[0008] Furthermore, the inner wall of the outer frame of the cable chain mechanism is fixedly connected to the outer wall of the chain body, and the other end of the outer wall of the chain body is fixedly connected to the outer wall of the inner frame of the cable chain mechanism.

[0009] This utility model has the following beneficial effects: In this invention, all pipelines on the cylinder are housed inside the chain, forming centralized protection for the pipelines. The pipelines are encased in the chain, preventing them from scraping or rubbing against external components during operation, thus avoiding equipment failure due to pipeline damage and reducing the equipment failure rate. The pipelines on the cylinder are arranged neatly inside the drag chain, with no scattered pipelines outside the chain, improving the machine's appearance. The chain provides a stable operating environment for the pipelines, reducing losses caused by external interference, extending the service life of the pipelines inside the chute drag chain, and lowering operating costs.
