"And / or" describes the association relationship of associated objects, indicating that three relationships can exist.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the relevant listed items.

[0044] See also Figures 1 to 6 The present application provides an overhead crane loading system, comprising a silo (not shown), a conveying device, and a material discharge device (not shown). The conveying device comprises a conveying pipeline and a compressed air treatment system (not shown). The compressed air treatment system generates compressed gas that transports the material in the silo to the material discharge device through the conveying pipeline. The compressed air treatment system may include multiple air compressors.

[0045] The delivery pipeline includes two delivery pipes 20 , a steering connection mechanism, and a second connection assembly 40 . The second connection assembly 40 is used to connect and communicate the steering connection mechanism and the delivery pipe 20 .

[0046] The steering connection mechanism includes multiple connecting tubes 100 and multiple first connecting assemblies 200. One of the first connecting assemblies 200 and one of the connecting tubes 100 are connected in a circular manner. That is, one first connecting assembly 200 is located between two adjacent connecting tubes 100 and connected to the two adjacent connecting tubes 100, and one connecting tube 100 is located between two adjacent first connecting assemblies 200 and connected to the two adjacent first connecting assemblies 200, thereby forming a conveying channel in series.

[0047] The first connecting assembly 200 includes a first connecting member 210 and a second connecting member 220. The first connecting member 210 includes a first tube body 211 and a first flange 212 and a second flange 213 connected to opposite sides of the first tube body 211. The first tube body 211 has a first connecting section that forms part of the conveying channel.

[0048] The second connecting member 220 includes a second tube body 221 and a third flange 222 and a fourth flange 223 connected to opposite sides of the second tube body 221 . The second tube body 221 has a second connecting section forming part of the conveying channel.

[0049] The first flange 212 and the fourth flange 223 are both used to connect to the connecting pipe 100, and the second flange 213 and the third flange 222 are connected so that the first connecting section and the second connecting section are connected, wherein the extension direction of the first connecting section and the extension direction of the second connecting section are set at an angle.

[0050] When the first connecting member 210 and the second connecting member 220 of the first connecting assembly 200 are connected to each other, the conveying direction of the conveying channel can be changed, thereby facilitating material loading. Furthermore, by interconnecting multiple connecting pipes 100 and multiple first connecting assemblies 200, a larger curvature can be achieved, thereby reducing friction and resistance of the material in the pipeline, improving material fluidity, and reducing the probability of material blockage at bends.

[0051] The pipeline system design implemented in the present application through multiple connecting pipes 100 and a first connecting component 200 can change the angle between the connecting pipes 100, thereby reducing the friction and resistance of the material in the pipeline. During the material transportation process, friction and resistance are often easily generated at the bends of the pipeline, affecting the flow speed and efficiency of the material. By increasing the bending curvature, the flow of materials in the pipeline can be smoother and energy loss can be reduced. By optimizing the bending curvature of the pipeline at the connection, pressure loss can be effectively reduced, and the stability and reliability of the system can be improved. It has multiple advantages such as reducing friction and resistance, reducing pressure loss, improving material fluidity, shortening feeding time and reducing the probability of blockage.

[0052] Among them, multiple connecting pipes 100 are connected through the first connecting component 200, and all are detachably connected by bolts, which has high flexibility and scalability. The number of connecting pipes 100 can be increased or decreased as needed, and the pipeline layout can be adjusted to adapt to different installation requirements.

[0053] The first flange 212 has a first opening connected to the first connecting section, and the second flange 213 has a second opening connected to the first connecting section. The first opening and the second opening are arranged at an angle. The second flange 213 has a third opening connected to the second connecting section, and the third flange 222 has a fourth opening connected to the second connecting section. The third opening and the fourth opening are arranged at an angle.

[0054] See also Figures 2 to 6The connecting pipe 100 includes a third pipe body 110 and a fifth flange 120 and a sixth flange 130 connected to opposite sides of the third pipe body 110. The fifth flange 120 and the sixth flange 130 of one connecting pipe 100 are connected to two first connecting assemblies 200 respectively.

[0055] The outer wall of the second flange 213 is connected to a ring-shaped limit block 214, and the outer wall of the third flange 222 is provided with a limit groove 224 adapted to the limit block 214. The limit block 214 is inserted into the limit groove 224, allowing the second flange 213 to rotate relative to the third flange 222.

[0056] The embodiment of the present application also includes multiple resistance-increasing components, each comprising a spring 310 and a resistance-increasing member 320 connected to one end of the spring 310. The third flange 222 defines a plurality of spring slots 225 spaced apart circumferentially about the limiting slot 224, the spring slots 225 communicating with the limiting slot 224. The spring 310 is positioned within the spring slot 225, with one end connected to the sidewall of the spring slot 225, allowing at least a portion of the resistance-increasing member 320 to extend into the limiting slot 224. The outer circumferential surface of the limiting block 214 defines a plurality of positioning slots adapted to mate with the resistance-increasing member 320.

[0057] In this embodiment, by the mutual cooperation between the set limit block 214 and the limit groove 224, the second flange 213 and the third flange 222 can rotate relative to each other, thereby realizing the adjustment of the direction and angle of the second flange 213 and the third flange 222, and then the angle between the two adjacent connecting pipes 100 can be adjusted, and the resistance-increasing member 320 is able to abut against the positioning groove under the elastic force of the spring groove 225, thereby increasing the friction between the second flange 213 and the third flange 222, reducing the probability of relative rotation between the first tube body 211 and the second tube body 221, and improving the stability between the two adjacent connecting pipes 100.

[0058] One end of the resistance increasing member 320 is spherical. When the first tube 211 and the second tube 221 rotate, the resistance increasing member 320 is squeezed and automatically contracts into the spring groove 225 .

[0059] See also Figure 1 The delivery pipe 20 includes a fourth pipe body 21 and a seventh flange 22 connected to one end of the fourth pipe body 21. The second connection assembly 40 includes a bellows 42 and an eighth flange 41 and a ninth flange 43 connected to opposite sides of the bellows 42.

[0060] Please refer to 7. The outer wall of the eighth flange 41 is connected to a plurality of first mounting blocks 44 distributed in a circular shape and at equal intervals. The outer wall of the ninth flange 43 is connected to a plurality of second mounting blocks 47 distributed in a circular shape and at equal intervals. The outer end of the first mounting block 44 is fixedly connected to a screw rod 45. The screw rod 45 passes through the second mounting block 47. The outer sleeve of the screw rod 45 is provided with two nuts 46. The two nuts 46 are respectively abutted against the two sides of the second mounting block 47.

[0061] In this embodiment, the position of the ninth flange 43 can be restricted and fixed by the provided nut 46 and screw 45, thereby limiting the telescopic length of the bellows 42, thereby enabling active fine-tuning according to the installation positions of the two conveying pipes 20, and further adjusting the pipeline layout to adapt to different installation requirements.

[0062] In addition, there are two second connecting assemblies 40 for connecting the two delivery pipes 20 with the connecting pipe 100 .

[0063] Working principle: First, the first connecting assembly 200 is installed between two adjacent connecting pipes 100 by bolts. During this process, the second flange 213 and the third flange 222 can be rotated by the mutual cooperation of the set limit block 214 and the limit groove 224, and the direction and angle of the second flange 213 and the third flange 222 can be adjusted, thereby completing the combination of multiple connecting pipes 100, and then the combined connecting pipe 100 is connected to the second connecting assembly 40 by bolts. Subsequently, by changing the distance between the eighth flange 41 and the ninth flange 43, the bellows 42 is stretched and contracted, and the position of the ninth flange 43 can be restricted and fixed by the nut 46 and the screw 45, so that active fine-tuning can be performed according to the installation position of the two conveying pipes 20. Finally, the two second connecting assemblies 40 are respectively connected to the two conveying pipes 20 to achieve communication between the two conveying pipes 20, thereby realizing the feeding of the alumina overhead crane.
