Description

Technical Field

[0001] This utility model belongs to the field of belt deflection prevention technology, specifically relating to a device for preventing deflection of a curved belt used for transporting sintered ore. Background Technology

[0002] Currently, curved belt conveyors are widely used in the transportation of sintered ore in sintering workshops. These belts are typically narrow (e.g., 800mm) and long (e.g., circumference up to 640 meters). Under no-load or heavy-load conditions, due to uneven belt tension distribution, asymmetrical material distribution, equipment installation errors, and foundation settlement, curved belts are prone to large swaying and uneven stress on both sides, leading to belt misalignment. Frequent misalignment not only affects transportation efficiency and equipment stability but also accelerates belt wear, increases maintenance frequency, seriously affects the continuity and safety of sintering production, and may even pose equipment damage and personnel safety hazards.

[0003] Although some anti-deviation devices exist in the existing technology, such as self-aligning idlers and vertical roller limiters, their structures often cannot adapt well to the unique tension and curvature changes of curved belts, and their anti-deviation effect is limited. Especially in long-distance, high-curvature curved belt systems, the problem of deviation is still difficult to solve fundamentally. Therefore, we propose an anti-deviation device for curved belts used in sintering ore transportation. Utility Model Content

[0004] To address the limited effectiveness of existing anti-deviation devices mentioned in the background section, particularly the persistent problem of deviation in long-distance, high-curvature curved conveyor belt systems, this invention provides an anti-deviation device for curved conveyor belts used in sintering ore transportation.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sinter ore transport arc belt anti-deviation device, comprising a support frame, a conveyor belt and a gantry frame, wherein a conveyor frame is fixedly connected to the inner side of the upper part of the support frame, and belt drive wheels are installed at both ends inside the conveyor frame, and a conveyor belt is sleeved on the outside of the belt drive wheels;

[0006] A gantry frame is installed above the conveying frame. A slot is opened on the inner side of the gantry frame, and a telescopic plate is movably installed in the slot. Support rods are fixed at both ends of the gantry frame, and mine car wheels are installed on the inner side of the support rods through a central shaft.

[0007] As a preferred embodiment of the anti-deviation device for the arc conveyor belt for sintered ore transportation according to this utility model, a positioning bolt is installed at the connection between the gantry frame and the telescopic plate, and the gantry frame and the telescopic plate are fixed by the positioning bolt.

[0008] As a preferred embodiment of the anti-deviation device for the arc conveyor belt used in sintering ore transportation according to this utility model, the gantry frame is welded from channel steel, and the width of the gantry frame can be adjusted by telescopic plates.

[0009] As a preferred embodiment of the anti-deviation device for the arc conveyor belt for sintering ore transportation according to this utility model, positioning rods are fixed at both ends of the middle part of the gantry frame, and telescopic columns are connected below the positioning rods. Support columns are movably connected below the telescopic columns.

[0010] In a preferred embodiment of the anti-deviation device for the arc conveyor belt used in sintering ore transportation according to this utility model, the telescopic column forms a telescopic structure with the support column, and the support column is fixed to the support frame by bolts.

[0011] As a preferred embodiment of the anti-deviation device for the arc conveyor belt for sintering ore transportation according to this utility model, the mine car wheels are symmetrically arranged above the two sides of the conveyor belt, and a set of mine car wheels is set every 10 meters along the length of the conveyor belt, for a total of 8 sets.

[0012] As a preferred embodiment of the anti-deviation device for the arc belt used in sintering ore transportation according to this utility model, the mine wheel is in close contact with the surface of the conveyor belt, and the gantry, support rod and mine wheel are all made of high temperature resistant and wear-resistant materials.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: By combining the gantry structure with the adjustable telescopic plate and the mine wheel, the device can effectively adapt to the uneven tension distribution of the curved belt in the curvature variation section. By loosening the positioning bolts to adjust the width of the gantry, the mine wheel can accurately fit the belt surface with different curvatures, widths and tensions, overcoming the defect of poor adaptability of traditional devices to curved sections. By adopting a multi-group distributed layout, the evenly distributed mine wheels form a continuous and stable mechanical constraint system on both sides of the belt. Through multi-point synergy, the deviation phenomenon is fundamentally suppressed, preventing the limited anti-deviation effect of existing anti-deviation devices, especially the problem of deviation that is difficult to fundamentally solve in long-distance, high-curvature curved belt systems.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1-4 As shown;

[0023] A device for preventing deviation of a sintered ore transport arc belt includes a support frame 1, a conveyor belt 3, and a gantry frame 4. A conveyor frame 2 is fixedly connected to the inner side of the upper part of the support frame 1. Belt drive wheels 8 are installed at both ends inside the conveyor frame 2, and the conveyor belt 3 is sleeved on the outside of the belt drive wheels 8. A gantry frame 4 is set above the conveyor frame 2. A slot 14 is opened on the inner side of the gantry frame 4. A telescopic plate 9 is movably installed in the slot 14. Support rods 5 are fixed at the lower ends of the gantry frame 4. Mining wheel wheels 6 are installed on the inner side of the lower part of the support rods 5 through a central shaft 7.

[0024] In this implementation plan: by combining the gantry frame 4 structure with the adjustable telescopic plate 9 and the mine wheel 6, the device can effectively adapt to the uneven tension distribution of the curved belt in the curvature variation section. By loosening the positioning bolts 10 to adjust the width of the gantry frame 4, the mine wheel 6 can accurately fit the belt surface with different curvatures, widths and tensions, overcoming the defect of poor adaptability of traditional devices to curved sections. By adopting a multi-group distributed layout, the evenly distributed mine wheel 6 forms a continuous and stable mechanical constraint system on both sides of the belt edge. Through multi-point synergy, the deviation phenomenon is fundamentally suppressed.

[0025] In an optional embodiment, a positioning bolt 10 is installed at the connection between the gantry frame 4 and the telescopic plate 9, and the gantry frame 4 and the telescopic plate 9 are fixed by the positioning bolt 10.

[0026] In this implementation plan, the gantry frame 4 and the telescopic plate 9 are fixed by positioning bolts 10, which makes the width adjustment operation simple and reliable, and ensures the rigidity and stability of the entire anti-deviation device structure during operation, thereby providing continuous and stable anti-deviation pressure.

[0027] In an optional embodiment, the gantry 4 is welded from channel steel, and the width of the gantry 4 can be adjusted by telescopic plate 9.

[0028] In this implementation plan: the gantry frame 4 is welded from channel steel, which is sturdy and has strong resistance to deformation. It can withstand various loads under the transportation conditions of sintered ore. The gantry frame 4 can be flexibly adjusted by telescopic plate 9 to adapt to different specifications of conveyor belt 3, which greatly enhances the versatility and applicability of the device.

[0029] In an optional embodiment, positioning rods 11 are fixed at both ends of the middle part of the gantry frame 4, and telescopic columns 12 are connected below the positioning rods 11. Support columns 13 are movably connected below the telescopic columns 12. The telescopic columns 12 and the support columns 13 form a telescopic structure, and the support columns 13 are fixed to the support frame 1 by bolts.

[0030] In this implementation plan, the telescopic structure consisting of positioning rod 11, telescopic column 12 and support column 13 can conveniently adjust the overall working height of gantry frame 4, so that the mine car wheel 6 can accurately fit the surface of conveyor belt 3 with different tension or different wear conditions, always maintain the best pressure contact, and ensure the anti-deviation effect.

[0031] In an optional embodiment, the mine car wheels 6 are symmetrically arranged above the two sides of the conveyor belt 3, with a set of mine car wheels 6 arranged every 10 meters along the length of the conveyor belt 3, for a total of 8 sets.

[0032] In this implementation plan: the mine car wheels 6 are symmetrically arranged above the two sides of the conveyor belt 3, which can mechanically constrain and correct the belt deviation trend from both sides at the same time. A distributed layout of 8 groups is set every 10 meters along the belt length direction, which can form a continuous and uniform limiting effect on the long-distance curved belt, effectively preventing the occurrence of local or overall deviation.

[0033] In an optional embodiment, the mine wheel 6 is in close contact with the surface of the conveyor belt 3, and the gantry 4, support rod 5 and mine wheel 6 are all made of high-temperature resistant and wear-resistant materials.

[0034] In this implementation plan: the mine wheel 6 is in close contact with the surface of the conveyor belt 3, ensuring the effective transmission of anti-deviation force and timely suppressing the belt deviation tendency. The gantry 4, support rod 5 and mine wheel 6 are all made of high temperature and wear-resistant materials, enabling the device to withstand the high temperature and wear characteristics of sintered ore, significantly extending its service life under harsh working conditions and reducing the frequency of maintenance and replacement.

[0035] Working principle:

[0036] A gantry frame 4 is installed above the curved conveyor belt 3. The gantry frame 4 is fixed to the support frame 1 by the support column 13 at its lower part. The gantry frame 4 is provided with telescopic plates 9 on both sides. The width of the gantry frame 4 can be changed by adjusting the positioning bolts 10 to adapt to conveyor belts 3 of different widths.

[0037] The gantry frame 4 is provided with a positioning rod 11 in the middle, which is connected to a telescopic column 12 and a support column 13. By adjusting this structure, the height of the entire gantry frame 4 can be adjusted so that the mine car wheel 6 below it is pressed against the surface of the belt. The mine car wheel 6 is symmetrically arranged above the two sides of the belt and is installed on the support rod 5 through the central shaft 7.

[0038] When the belt is running, the mine car wheel 6 is in close contact with the belt surface and applies a certain downward pressure to form a lateral constraint on the belt, preventing it from deviating to one side. Multiple sets of this device are arranged at 10-meter intervals along the length of the belt, for a total of 8 sets, forming a continuous and stable limiting effect to ensure that the belt can maintain centering even in curved sections.

[0039] Both the gantry frame 4 and the mine car wheel 6 are made of wear-resistant alloy materials, which are resistant to high temperature and wear, and are suitable for sinter transportation conditions.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
