Description

Technical Field

[0001] This utility model belongs to the field of ship loaders, specifically relating to a material conveying structure and a ship loader for optimizing the material throwing method of a ship loader. Background Technology

[0002] In port cargo handling operations, ship loaders are one of the important pieces of equipment. Their main function is to transport materials from the dock to the ship's hold in order to complete the cargo loading process.

[0003] Currently, traditional ship loaders mainly consist of a boom conveyor, telescopic chute, tail car, traveling device, and pitching device. During the material throwing operation, the conveyor belt usually transports the material to the upper receiving position of the telescopic chute, and then the telescopic chute and the bend at its lower end throw the material into the ship's hold.

[0004] However, existing ship loaders still have certain shortcomings in use. Specifically, since existing ship loaders were initially designed to meet the loading needs of ships under 50,000 tons, the length of the telescopic chute is designed based on the theoretical height of such ships. However, in actual berthing, ships of 30,000 to 50,000 tons are often more than 5 meters higher than the wharf surface. Therefore, it is necessary to wait for low tide or add ballast water to adjust the ship's draft to ensure that the telescopic chute can be smoothly aligned with and moved between holds. As a result, there are problems such as excessively long shifting time and long downtime of the ship loader. At the same time, because the existing elbow throwing plate is set at a 60-degree arc, it is easy for the material to land too far away during the throwing process. This causes the telescopic chute to need to move frequently during hold-opening operations, which affects the operation efficiency and makes hold-opening time too long. Utility Model Content

[0005] The purpose of this invention is to address the problems of long alignment time and long loading time in the actual application of the material conveying structure configured in existing ship loaders. It proposes and designs a material conveying structure and ship loader to optimize the material throwing method of the ship loader. This structure can shorten the alignment time of the telescopic chute to reduce the downtime of the ship loader, and adjust the material throwing position at the bend to improve the loading efficiency of the entire ship loader.

[0006] To achieve the above objectives, on the one hand, this utility model provides a material conveying structure for optimizing the material throwing method of a ship loader, which includes a fixed support, an inner fixed chute installed on the fixed support, an outer movable chute vertically slidingly sleeved on the outer side of the inner fixed chute, a lifting drive mechanism between the outer movable chute and the inner fixed chute, the length of the outer movable chute being 5.8 meters, and an elbow hinged to the lower end of the outer movable chute, the two ends of the elbow being respectively set as a flat section and an arc section, and an opening and closing drive mechanism being installed between the flat section of the elbow and the outer movable chute, the length of the flat section of the elbow being 1.5 meters, one end of the arc section of the elbow being tangent to the flat section, and the central angle corresponding to the arc section of the elbow being 12.8°. At this point, on the one hand, this utility model can significantly shorten the length of the entire material conveying structure by shortening the outer movable chute by 0.8 meters, thereby ensuring that it can smoothly carry out the chamber operation without stopping and waiting; on the other hand, it can significantly shorten the length of the bend to reduce the time of material sliding on the flat section, thereby reducing the material drop position difference and improving the bend throwing distance.

[0007] Furthermore, the upper part of the inner fixed chute is horizontally rotatably mounted on a fixed support. A driven gear ring is fixedly mounted on the outer wall of the inner fixed chute, and the driven gear ring meshes with a driving gear. The driving gear is connected to a drive motor, which is fixedly mounted on the lower surface of the fixed support. In this configuration, the present invention can drive the inner fixed chute, the outer movable chute, and the elbow to rotate together via the drive motor, thereby changing the material throwing direction of the elbow. Moreover, compared to the existing technology where the rotary drive mechanism is located at the elbow, this structure not only reduces the pollution level of the entire drive structure, extending its service life, but also simplifies the installation structure of the elbow and the opening / closing drive mechanism, making it easier for workers to replace the elbow.

[0008] Furthermore, the outer wall of the inner fixed chute is provided with at least one sliding protrusion, and the outer wall of the outer movable chute is provided with at least one sliding groove. The sliding groove is vertically slidably connected to the corresponding sliding protrusion to ensure that the outer movable chute can slide smoothly relative to the inner fixed chute and to ensure that the outer movable chute can rotate horizontally together with the inner fixed chute.

[0009] Furthermore, an inductive switch is installed below the fixed support, which is electrically connected to the drive motor. A trigger is installed on the upper part of the outer movable chute, which can trigger the inductive switch. The cooperation between the trigger and the inductive switch ensures that the outer movable chute will not collide with the rotary drive mechanism.

[0010] Furthermore, the opening and closing drive mechanism includes a drive hydraulic cylinder. The cylinder body end of the drive hydraulic cylinder is hinged to the outer wall of the outer movable chute through a hinge seat, and the piston rod end of the drive hydraulic cylinder is hinged to the end of the elbow through a hinge seat. The opening and closing angle of the elbow is changed by the relative movement of the piston rod and the cylinder body inside the drive hydraulic cylinder.

[0011] Furthermore, a liner is laid on the surface of the elbow that comes into contact with the material, and the elbow is protected by the liner to reduce wear on the elbow during the collision with the material.

[0012] On the other hand, this utility model also provides a ship loader, which includes the above-mentioned material conveying structure for optimizing the material throwing method of the ship loader, and realizes the corresponding ship loading operation through the above-mentioned material conveying structure for optimizing the material throwing method of the ship loader.

[0013] As can be seen from the above technical solutions, this utility model has the following advantages:

[0014] 1. This utility model can shorten the length of the entire material conveying structure by significantly shortening the outer movable chute by a certain length, thereby ensuring that it can be smoothly operated in the hopper without stopping and waiting;

[0015] 2. This utility model can significantly shorten the material slippage time on the flat section by shortening the bend of a certain length, thereby reducing the material drop position difference and improving the bend throwing distance;

[0016] 3. By placing the rotary drive mechanism below the fixed support, this utility model can not only reduce the degree of pollution of the entire drive structure and extend the service life of the entire rotary drive structure, but also simplify the installation structure of the elbow and the opening and closing drive mechanism, making it easier for workers to replace the elbow.

[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Example 1

[0022] like Figure 1 As shown, this embodiment provides a material conveying structure for optimizing the material throwing method of a ship loader. It includes a fixed support 10 that can be fixedly installed on the ship loader. The fixed support 10 has a mounting hole in the middle, and an inner fixed chute 9 is horizontally rotatably installed at the mounting hole through a rotating mounting structure such as a bearing. The upper end of the inner fixed chute 9 passes through the fixed support 10 and is equipped with a receiving funnel. The receiving funnel is connected to the belt conveyor of the ship loader to realize the material receiving action.

[0023] The lower end of the inner fixed chute 9 passes through the fixed support 10 and is sequentially arranged from top to bottom as a rotary drive mechanism and an outer movable chute 7. The rotary drive mechanism includes a driven gear ring 8 fixedly installed on the outer wall of the inner fixed chute 9. The driven gear ring 8 meshes with a driving gear 3. The driving gear 3 is connected to a drive motor 1, and the drive motor 1 is fixedly installed on the lower surface of the fixed support 10.

[0024] The outer movable chute 7 is vertically slidably installed on the outside of the inner fixed chute 9, and a lifting drive mechanism is provided between the outer movable chute 7 and the inner fixed chute 9. Specifically, in this embodiment, the lifting drive mechanism can be a winch and a wire rope, that is, a winch is provided on the upper part of the inner fixed chute 9, a wire rope is provided on the outside of the outer movable chute 7, and the end of the wire rope is wound on the winch's shaft, thereby realizing the relative movement between the outer movable chute 7 and the inner fixed chute 9 through the movement of the winch and the wire rope. Furthermore, in order to ensure that the outer movable chute 7 can slide smoothly vertically along the length of the inner fixed chute 9 and rotate horizontally with the inner fixed chute 9, this embodiment also provides at least one sliding protrusion on the outer wall of the inner fixed chute 9 and at least one sliding groove on the outer wall of the outer movable chute 7, and makes the sliding groove vertically slidably connected to the corresponding sliding protrusion, thereby ensuring that the outer movable chute 7 can slide smoothly vertically relative to the inner fixed chute 9 and that the outer movable chute 7 can rotate horizontally together with the inner fixed chute 9.

[0025] To prevent the outer movable chute 7 from colliding with the rotary drive mechanism, in this embodiment, an inductive switch 2 is installed below the fixed support 10 and electrically connected to the drive motor 1. A trigger 4 is installed above the outer movable chute 7, enabling the trigger 4 to activate the inductive switch 2. The interaction between the trigger 4 and the inductive switch 2 constrains the outer movable chute, preventing it from colliding with the rotary drive mechanism. Alternatively, a mechanical hard-limiting structure can also be used.

[0026] Meanwhile, the outer movable chute 7 is 5.8 meters long and can be obtained directly by cutting off the upper part of an existing outer movable chute 7 from top to bottom. An elbow 5 is hinged to the lower end of the outer movable chute 7, with the two ends of the elbow 5 being a flat section and an arc section, respectively. An opening and closing drive mechanism 6 is installed between the flat section of the elbow 5 and the outer movable chute 7. The opening and closing drive mechanism 6 includes a driving hydraulic cylinder, and the cylinder body end of the driving hydraulic cylinder is hinged to the outer wall of the outer movable chute 7 via a hinge seat. The piston rod end of the driving hydraulic cylinder is hinged to the end of the elbow via a hinge seat. Furthermore, the length of the planar section of the elbow 5 is 1.5 meters, and it can be obtained by cutting off a portion of the existing elbow 5 from top to bottom; one end of the arc section of the elbow 5 is tangent to the planar section, and the central angle corresponding to the arc section of the elbow 5 is 12.8°; a liner is laid on the surface of the elbow 5 that is used to contact the material, and the elbow 5 is protected by the liner to reduce the wear of the elbow 5 during the collision and contact with the material.

[0027] Based on this, when using this embodiment, on the one hand, the length of the entire material conveying structure can be shortened by significantly reducing the length of the outer movable chute 7, thereby increasing the boom tilt angle of the ship loader by 4°, ensuring smooth docking operations without the need for downtime; on the other hand, the material slippage time on the flat section can be reduced by significantly shortening the length of the bend 5, thereby reducing the material drop position difference and improving the throwing distance of the bend 5. Simultaneously, by placing the rotary drive mechanism below the fixed support 10, the degree of contamination of the entire drive structure can be reduced, thus extending the service life of the entire rotary drive structure.

[0029] This second embodiment provides a ship loader, which includes the material conveyor structure described in the first embodiment for optimizing the material throwing method of the ship loader, and realizes the corresponding ship loading operation through the material conveyor structure described above for optimizing the material throwing method of the ship loader.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
