Description

Technical fields:

[0001] This utility model belongs to the field of coal coking production, and in particular relates to a coal loading box conveying device for high-sulfur coal blending and coking experiments. Background technology:

[0002] In the coal coking industry, the impact of high-sulfur coal at different addition ratios on the coking process is crucial. A scientifically sound coal blending scheme can reduce the sulfur content in coke while maintaining or improving its quality indicators, such as cold strength and hot performance, to meet the stringent requirements of modern blast furnace smelting. Furthermore, the appropriate addition ratio of high-sulfur coal in coking is significant for improving resource utilization efficiency and reducing environmental pollution.

[0003] To ensure the proper addition of high-sulfur coal in coking blends, relevant coking experiments need to be conducted before production begins to obtain relevant data. Small coke ovens are commonly used equipment in laboratories. Before the experiment, the prepared coal needs to be placed into a coal charging box, and a small manual forklift is used to transfer the heavier coal charging box to the convex lifting platform of the small coke oven. Once ready, the convex lifting platform raises the coal charging box and extends it into the furnace of the small coke oven, which has an opening at the bottom, for high-temperature heating. However, in actual operation, because the forks of the small manual forklift directly lift the coal charging box, the coal charging box is not stable enough during movement and is prone to falling, causing deformation or damage to the coal charging box. Moreover, the coal charging box cannot be accurately placed on the convex lifting platform, requiring repeated adjustments, which is time-consuming and labor-intensive. When adjusting the position of the coal charging box, the forks of the small manual forklift are prone to hitting the convex lifting platform, thereby damaging the small coke oven and affecting the normal progress of the coking experiment. Summary of the Invention:

[0004] The purpose of this utility model is to provide a coal loading box conveying device for high-sulfur coal blending and coking experiments, and to overcome the shortcomings of the above-mentioned prior art, effectively solving the existing problem of unstable coal loading box transfer.

[0005] The present invention relates to a coal loading box conveying device for high-sulfur coal blending and coking experiments, comprising a frame-shaped trailer made of three angle steels, with hooks installed on both horizontal arms of the frame-shaped trailer, and the width of the groove of the frame-shaped trailer being the same as the width of the coal loading box.

[0006] Furthermore, the notch width of the frame-shaped bracket is the same as the convex top width of the small coke oven lifting platform.

[0007] Furthermore, the hook is right-angled.

[0008] Furthermore, the width of the hook's slot is the same as the width of the forklift's forks.

[0009] Furthermore, chamfers are provided at the outer ends of both cross arms of the frame-shaped bracket.

[0010] The beneficial effects of this utility model are: the frame-shaped trolley can place the coal box stably and accurately on the small coke oven lifting platform, saving time and effort, and preventing the coal box from falling during transportation and movement, thus ensuring the normal progress of coking experiments.

[0014] Figure 4 This is a usage state diagram of the main view of this utility model;

[0015] In the picture, 1 is a frame-shaped bracket, 2 is a hook, 3 is a small coke oven lifting platform, and 4 is a coal loading box. Detailed implementation method:

[0016] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings:

[0017] like Figures 1 to 4 As shown, the coal loading box conveying device for high-sulfur coal blending and coking experiments includes a frame-shaped tractor 1 spliced ​​from three angle steels. Hooks 2 are installed on both horizontal arms of the frame-shaped tractor 1. The width of the groove in the frame-shaped tractor 1 is the same as the width of the coal loading box 4. The width of the notch in the frame-shaped tractor 1 is the same as the width of the convex top of the small coke oven lifting platform 3. The hooks 2 are right-angled. The width of the hanging groove of the hooks 2 is the same as the width of the forklift forks. Chamfers are provided at the outer ends of both horizontal arms of the frame-shaped tractor 1.

[0018] Specifically, the frame-shaped bracket 1 can be used to place the coal box 4 stably and accurately on the small coke oven lifting platform 3.

[0019] In actual use, the coal loading box 4 is first placed on the frame-shaped bracket 1. The angle steel frame-shaped bracket 1 ensures that the two right-angled sides of the frame-shaped bracket 1 fit tightly against the side and bottom walls of the coal loading box 4. Furthermore, the width of the groove in the frame-shaped bracket 1 is the same as the width of the coal loading box 4, allowing the coal loading box 4 to be placed more stably within the frame-shaped bracket 1 without moving. Then, the experimental coal is placed into the coal loading box 4 according to the technical requirements. After preparation, the forks of the small manual forklift are inserted into the hooks 2, and the frame-shaped bracket 1 and the coal loading box are then connected. 4. Lifting: When the forklift moves, the width of the hook 2's groove is the same as the width of the forklift's forks, making the frame-shaped trailer 1 more stable when moving. When the coal box 4 is lifted to the small coke oven lifting platform 3, the notch of the frame-shaped trailer 1 is the same as the width of the convex top of the small coke oven lifting platform 3, so that the frame-shaped trailer 1 can be quickly and accurately inserted into the convex top of the small coke oven lifting platform 3. After the coal box 4 is placed steadily, the forklift's forks are lowered to leave the experimental area. At this time, the small coke oven lifting platform 3 is raised to allow the coal box 4 to extend into the furnace of the small coke oven to complete the heating.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
