Description

Technical Field

[0001] This utility model belongs to the technical field of dry bulk cargo port transportation and loading equipment, and relates to an anti-spillage structure suitable for the tail car of a vertical ship loader with small curvature and large angle of inclination. Background Technology

[0002] In the loading of dry bulk cargo, ship loaders are common large-scale dry bulk cargo loading equipment. Due to the high investment cost of wharves, and the fact that the length of the ship loader's tail car directly affects the investment in civil engineering foundations, the tail car of a typical ship loader is relatively short. This results in the center of curvature of the curve connecting the horizontal section of the belt conveyor to the tail car being directly above the belt, with a small curvature, and the tail car having a large inclination angle.

[0003] When this type of vertical, low-curvature, high-angle tail car belt conveyor is running unloaded or lightly loaded, it cannot rely on the gravity generated by the belt and material load (if present) to press the belt against the idlers. Instead, the tension in the belt tends to lift it away from the idlers. When the loading section of the conveyor belt approaches the tail car of a low-curvature, high-angle ship loader, the lack of trough support can lead to material spillage. This spillage is common at coal loading terminals. Due to the large investment in ship loaders and the complex structure of the tail car, as well as the limited space on site, it is crucial to design a spillage prevention structure suitable for the vertical, low-curvature, high-angle tail car of a ship loader. This can not only effectively reduce cargo loss for customers and improve the environmental quality of coal ports, but also reduce the labor costs required to clean up spilled coal. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a spill prevention structure suitable for the tail car of a vertical ship loader with small curvature and large angle of inclination.

[0005] The technical problem solved by this utility model is achieved through the following technical solution: A spill prevention structure suitable for the tail car of a ship loader with small vertical curvature and large inclination angle is characterized by comprising a belt pressure pulley and an anti-overflow component. The spill prevention structure is installed at the transition position between the horizontal section and the inclined section of the ship loader belt, forming a belt transition section. A belt pressure pulley is pressed onto the upper part of both the front and rear ends of the belt transition section, and an anti-overflow component is provided on the two outer sides of the belt pressure pulley along the belt length direction.

[0006] Furthermore, the pressure roller includes a bearing frame, a wheel axle, side pressure plates and a middle pressure plate. Bearing frames are symmetrically installed on the frames at both ends of the belt. A wheel axle is rotatably installed between the two bearing frames. A middle pressure plate is fixed in the middle of the wheel axle. Side pressure plates are spaced apart at both ends of the middle pressure plate.

[0007] Furthermore, the cross-section of the central pressure strip is circular, and the cross-section of the edge pressure strip is tapered with a narrow outer side and a wide inner side.

[0008] Furthermore, the overflow prevention assembly includes mounting columns, mounting beams, an overflow prevention plate, a first overflow prevention skirt, and a second overflow prevention skirt. Mounting columns are installed on the frame on both sides of the belt. Two parallel transverse adjustment holes are provided at the upper end of the mounting columns. The mounting beam is installed on the transverse adjustment holes by screws and nuts. A connecting plate is provided at the front end of the mounting beam. An overflow prevention plate connection hole is provided on the connecting plate. The overflow prevention plate includes a vertical section and an inclined section. A vertical adjustment hole is provided on the vertical section. The vertical adjustment hole is connected to the overflow prevention plate connection hole by screws and nuts. The first overflow prevention skirt is installed on the inner side of the inclined section of the overflow prevention plate along its slope. The second overflow prevention skirt is installed vertically on the outer side of the inclined section of the overflow prevention plate by a bracket.

[0009] The advantages and positive effects of this utility model are: This spill prevention structure, applicable to the tail car of a ship loader with a small vertical curvature and a large angle of inclination, provides effective trough-shaped support for the belt transition section of the tail car. When the belt is lifted under light load, it allows material to come into contact with the pressure pulley, and any resulting splashing material is contained within the double-layered spill prevention components, effectively reducing spillage. This device successfully solves the material spillage problem in the tail car area of ​​a ship loader with a small vertical curvature and a large angle of inclination. Attached Figure Description

Detailed Implementation

[0012] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings: An anti-spillage structure suitable for the tail car of a vertical ship loader with small curvature and large angle of inclination, its innovation lies in: including a pressure roller 1 ( Figure 1The diagram shows a belt pressing plate of a belt pressing pulley and an anti-overflow component 2. The anti-overflow structure is installed at the transition position from the horizontal section to the inclined section of the ship loader belt 4. This transition position forms a belt transition section. Belt pressing pulleys are pressed onto the upper part of both the front and rear ends of the belt transition section. Anti-overflow components are provided on the two outer sides of the belt pressing pulleys along the belt length direction.

[0013] The pressure pulley includes a bearing frame, a wheel axle, side pressure plates 11, and a central pressure plate 12. Bearing frames are symmetrically mounted on the frame 3 at both ends of the belt. A wheel axle is rotatably mounted between the two bearing frames. A central pressure plate is fixedly mounted in the middle of the wheel axle. Side pressure plates are spaced apart at both ends of the central pressure plate. The groove between the side pressure plates and the central pressure plate forms a material passage groove. By designing the pressure pulley as a rotatable structure, friction between it and the material and the belt is reduced, extending the service life of both the belt and the pressure pulley. Figure 1 As shown, the edge pressing strip tail plate structure serves to press the belt together.

[0014] like Figure 4 As shown, the cross-section of the central pressure plate is circular, and the cross-section of the side pressure plate is a tapered structure that is narrow on the outside and wide on the inside. The slope of this tapered structure is consistent with the slope of the side idler roller 13. When the belt is lifted under light load, the two sides of the belt can still maintain an inclined state under the action of the pressure roller, ensuring that the material is centered.

[0015] Material diverted by the belt pulley can be prevented from overflowing through the anti-overflow assembly. The anti-overflow assembly includes mounting columns 6, mounting beams 7, anti-overflow plates 8, a first anti-overflow skirt 10, and a second anti-overflow skirt 9. Mounting columns are installed on the frame on both sides of the belt. Two parallel transverse adjustment holes are provided at the upper end of the mounting columns. The mounting beam is installed in the transverse adjustment holes using screws and nuts. A connecting plate is provided at the front end of the mounting beam, and an anti-overflow plate connection hole is provided on the connecting plate. The anti-overflow plate includes a vertical section and an inclined section. A vertical adjustment hole is provided in the vertical section, which is connected to the anti-overflow plate connection hole using screws and nuts. The first anti-overflow skirt is installed on the inner side of the inclined section of the anti-overflow plate along its slope, and the second anti-overflow skirt is vertically installed on the outer side of the inclined section of the anti-overflow plate via a bracket 5.

[0016] The first spill guard is made of ultra-high molecular weight polyethylene, which can effectively block direct impact and splashing impact of materials under light loads, preventing materials from overflowing from the edges. The second spill guard is made of canvas flat tape, which has a certain degree of flexibility and can effectively block splashing impact of materials, preventing bouncing materials from overflowing from the edges.

[0017] During installation, the position of the spill prevention plate can be adjusted according to the site conditions to ensure effective cooperation between the first and second spill prevention skirts and the belt.
