Description

A multi-purpose scraper-type ship loading and unloading machine

Technical Field

The present application relates to the technical field of bulk material loading and unloading, and in particular to a multi-purpose buried scraper type integrated loading and unloading ship machine.

Background Art

With the vigorous development of global trade, bulk cargo terminals, as important nodes for cargo transshipment, have become important indicators for measuring the competitiveness of terminals in terms of operational efficiency, environmental protection performance and automation level. Currently, domestic and foreign bulk cargo terminals are undergoing a transformation and upgrading from traditional to large-scale, efficient, green and intelligent. Especially in grain bulk cargo terminals, due to their large cargo flow and high transshipment frequency, the performance requirements for equipment are more stringent.

The traditional material transfer and dock transshipment system mainly relies on cranes to grab materials from large ships into hoppers, and then transport them to ship loaders through belt conveyor systems for loading operations. Although this system meets the basic needs of material transfer to a certain extent, it has exposed many shortcomings during actual operation. For example, materials are easily scattered during the process of crane grabbing materials, resulting in serious dust pollution in the dock area, which does not meet the environmental protection requirements of modern docks.

In the relevant technologies, with the prohibition of water transshipment and the increase in the demand for dock transshipment, the demand for professional bulk material unloading and loading transshipment equipment or all-in-one machines (with environmentally friendly and efficient characteristics) has become more and more urgent. Therefore, the traditional material transfer and dock transshipment system can no longer meet the needs of the development of modern docks, and there is an urgent need to find a more efficient and environmentally friendly material transfer solution.

According to the extension and retraction of its piston rod, the first boom 2 is pushed or pulled to pitch. The first boom 2 will be lifted or lowered accordingly to adjust its angle relative to the horizontal plane. During the process of the boom pitching, the operator needs to monitor the angle and position of the boom in real time to ensure that it reaches the expected pitch angle. After reaching the required pitch angle, the pitch cylinder 133 is stopped and the position of the boom is fixed;

Start the swing arm oil cylinder 52, and the output end of the swing arm oil cylinder 52 begins to generate thrust or pulling force (depending on the direction in which the vertical scraper 3 needs to swing). When the swing arm oil cylinder 52 is working, the vertical scraper 3 will swing around the hinge point until the vertical scraper 3 swings to a predetermined position. The operator stops the operation of the swing arm oil cylinder 52 through the control system, and the output end of the swing arm oil cylinder 52 stops generating thrust or pulling force, and the vertical scraper 3 remains in the new position, ready for subsequent material conveying work;

The head bucket 23 of the gantry scraper 8 is aligned with the material receiving port of the wharf belt conveyor, ready for subsequent material transportation work;

The material is first transported from the dock or yard to the arm scraper 4 through the vertical buried scraper 3. The material continues to be transported forward in the arm scraper 4. After reaching the end thereof, the material enters the buffer silo 15 through the central trough 14, and finally enters the gantry scraper 8 from the discharge end of the buffer silo 15. The material continues to be transported forward, and finally passes through the loading belt telescopic barrel 23, falls into the belt conveyor of the dock, and is finally loaded into the yard warehouse;

When the "ship loading" mode is selected, the position of the first boom 2 is adjusted, and the two driving motors 73 are started at the same time. The rotation of the driving motor 73 will drive the small driving gear 72 to rotate, and the two driving small driving gears 72 are meshed with the rotating large gear 71, driving the rotating large gear 71 to rotate, and the unloading rotating column 6 will also rotate accordingly, and finally drive the first boom 2 to rotate to point to the target position, and start the pitch cylinder 133. According to the extension and retraction of its piston rod, the first boom 2 is pushed or pulled to pitch. The first boom 2 will be lifted or lowered accordingly to adjust its angle relative to the horizontal plane. During the process of the boom pitching, the operator needs to monitor the angle and position of the boom in real time to ensure that it reaches the expected pitch angle. After reaching the required pitch angle, the pitch cylinder 133 is stopped and the position of the boom is fixed;

Start the swing arm oil cylinder 52, and the output end of the swing arm oil cylinder 52 begins to generate thrust or pulling force (depending on the direction in which the vertical scraper 3 needs to swing). When the swing arm oil cylinder 52 is working, the vertical scraper 3 will swing around the hinge point until the vertical scraper 3 swings to a predetermined position. The operator stops the operation of the swing arm oil cylinder 52 through the control system, and the output end of the swing arm oil cylinder 52 stops generating thrust or pulling force, and the vertical scraper 3 remains in the new position, ready for subsequent material conveying work;

Through the loading slewing mechanism 20, the second boom 17 can be rotated in the horizontal direction to ensure that the boom belt conveyor 9 can accurately align with the loading position. Once the loading position is determined, the loading pitch mechanism 18 starts to work, and the servo motor 181 drives the winding drum 182 to rotate, controls the retraction and release of the wire rope 183, and accurately adjusts the pitch angle of the second boom 17 to ensure that the boom belt conveyor 9 can effectively transport the materials to the interior;

The material is first transported from the dock or yard to the arm scraper 4 through the vertical buried scraper 3. The material continues to be transported forward in the arm scraper 4. After reaching the end thereof, the material enters the buffer silo 15 through the central trough 14, and finally enters the gantry scraper 8 from the discharge end of the buffer silo 15. The material is further transported forward to the transition scraper 21, and is transferred through the transition scraper 21. The material enters the arm belt conveyor 9 through the ship loading rotary chute 22, and the material is transported to the ship loading telescopic barrel 10, and finally thrown into the cabin by the ship loading throwing spoon 11;

Through the arrangement of vertical buried scrapers 3, arm scrapers 4, gantry scrapers 8, etc., a continuous and efficient material conveying system is formed, which effectively transfers materials from one place to another, reduces the interruption and waiting time in the traditional loading and unloading process, greatly improves work efficiency, can adapt to different work scenes and needs, improves the versatility and adaptability of the equipment, and adopts buried scraper conveying method to reduce the scattering and dust of materials in the conveying process, which is beneficial to environmental protection. The all-in-one machine integrates multiple functions such as unloading, loading, entering the yard or warehouse, etc., and realizes multiple operations through one device, which greatly saves space and cost. Compared with the traditional material conveying line system, the all-in-one machine has a smaller investment, but more comprehensive functions, higher cost performance, and adopts a compact structural design to reduce the footprint, so that it can be well used even when the dock space is compact.
