Abstract
Description
Technical Field
[0001] This invention relates to the field of belt conveyor technology, and more specifically to a sling belt conveyor system. Background Technology
[0002] Belt conveyors are friction-driven, continuous material transport systems. They offer advantages such as large conveying capacity, simple structure, easy maintenance, low cost, and versatility, and are widely used in metallurgy, coal mining, transportation, hydropower, and chemical industries. Belt conveyor systems typically have large spans, potentially crossing railways, highways, or valleys, making the construction of trestle bridges essential. Current technology often uses steel trusses as overhead structures to support the conveying mechanism, creating integrated belt conveyors, which are widely used in long-distance conveyor belt projects. However, steel trusses require a large number of steel beams, resulting in a complex structure and significant weight. Furthermore, current truss structures are mostly simply supported, requiring ground-mounted columns for support at intervals. This leads to significant deflection and deformation over large spans, making them unsuitable for scenarios involving large spans in mountainous areas or valleys, thus limiting their application. Summary of the Invention
[0003] In view of this, the present invention provides a sling belt conveyor system to solve the problems of complex truss structure, heavy weight and unsuitability for large span scenarios of belt conveyor systems.
[0004] This invention provides a sling conveyor system, comprising: at least two support sections; a sling assembly connected between two adjacent support sections, the sling assembly including multiple parallel slings; a plurality of support components connected to the sling assembly, the plurality of support components being spaced apart along the extension direction of the slings, each support component including a base beam and multiple tie rods, the base beam being horizontally arranged and perpendicular to the extension direction of the slings, each tie rod being connected between two adjacent slings or between the base beam and a sling to form a polygonal frame perpendicular to the extension direction of the slings; and a conveying mechanism extending along the extension direction of the slings, the conveying mechanism being located in the receiving space enclosed by the sling assembly and the support components and supported by the base beam.
[0005] Beneficial effects: By setting up a support unit to connect and support the sling assembly, and connecting the support assembly to the sling assembly, a conveying mechanism is set up in the accommodating space enclosed by the sling assembly and the support assembly, thus forming an integrated conveying system with a simple structure. The polygonal frame formed by the support assembly has good support capacity. The support assembly and the sling assembly are interconnected and support each other to form a stable structural system. At the same time, the base beam can provide stable support for the conveying mechanism, improving the stability of the entire system. Furthermore, the sling is a flexible component with strong load-bearing capacity, and the tie rod structure in the support assembly is simple, lightweight, and high-strength. Therefore, the support structure formed by the sling assembly and the support assembly is simple in construction, lightweight, and has strong overall rigidity, thus having a strong spanning capacity. It is suitable for large-span scenarios such as valleys with complex terrain or wide rivers, with a wide range of applications and low construction cost.
[0006] In one optional embodiment, the sling assembly includes: a crossbeam cable disposed at the top of the sling conveyor system; two stabilizing cables located below the crossbeam cable, the two stabilizing cables being disposed on both sides of the sling conveyor system along the width direction; and a bridge deck cable located below the stabilizing cables to support the base beam.
[0007] Beneficial effects: The crossarm and deck cables serve as load-bearing components to support the weight of the bridge deck. The stabilizing cables on both sides are used to bear the lateral wind load of the entire bridge deck system. On the other hand, they form a polygonal system with the crossarm and deck cables through the support components to stabilize and support the conveying mechanism and improve the stability of the system.
[0008] In one alternative embodiment, the plurality of tie rods includes two first tie rods and two second tie rods, the first tie rods being connected between the crossbeam and the stabilizing cable, and the second tie rods being connected between the stabilizing cable and the base beam, the base beam, the two first tie rods and the two second tie rods forming a pentagonal frame perpendicular to the extension direction of the sling.
[0009] Beneficial effects: The first tie rod fixes the relative distance between the crossarm cable and the stabilizing cable, and the second tie rod fixes the relative distance between the stabilizing cable and the base beam. At the same time, the base beam is fixed to the bridge deck cable, thereby achieving relative support and fixation between the suspender cable assembly and the support assembly. The pentagonal frame formed by the support assembly has good stability and good torsional resistance. The stabilizing cable, through the tie rod and the base beam, together with the crossarm cable and the bridge deck cable, forms a torsional stabilization system with a pentagonal cross section, improving the torsional resistance of the suspender cable conveyor system, thereby improving the system's stability and reducing the impact of lateral wind loads.
[0010] In one optional embodiment, the conveying mechanism includes: a support frame connected to the base beam; a roller frame and a roller assembly, the roller frame being fixed to the support frame and the roller assembly being rotatably disposed on the roller frame; and a conveyor belt disposed on the roller assembly and in rolling contact with the roller assembly, the conveyor belt being adapted to move along the extension direction of the sling.
[0011] Beneficial effects: The support frame supports the idler frame, the idler frame supports the idler assembly, and the idler assembly supports the conveyor belt, thus supporting the conveyor belt. Furthermore, the rolling contact between the conveyor belt and the idler assembly reduces the friction during the conveyor belt's operation, thereby reducing the driving force required to move the conveyor belt, thereby reducing energy consumption and costs.
[0012] In one optional embodiment, the sling conveyor system further includes: a longitudinal beam parallel to the sling, the longitudinal beam being disposed on the base crossbeam, and the support frame being disposed on the longitudinal beam.
[0013] Beneficial effects: The base beam supports the longitudinal beam, which in turn provides support for the support frame. The support columns of the support frame are indirectly connected to the base beam through the longitudinal beam, thus the base beam provides support for the support frame, resulting in good stability. Furthermore, since the extension direction of the longitudinal beam is the same as and continuous with the extension direction of the sling conveyor system, the spacing between two adjacent support frames can be customized according to the needs of the sling conveyor system, offering high flexibility.
[0014] In one optional embodiment, the sling conveyor system further includes: a fixed connector and an elastic connector, the fixed connector being fixed to the base beam, and the elastic connector passing through the fixed connector and the longitudinal beam in sequence to connect the fixed connector and the longitudinal beam.
[0015] Beneficial effects: The fixed connector is fixedly connected to the base crossbeam and to the longitudinal beam, thus achieving the connection between the longitudinal beam and the base crossbeam through the fixed connector. Furthermore, the longitudinal beam and the fixed connector are elastically connected through the elastic connector, achieving an indirect elastic connection between the longitudinal beam and the base crossbeam. On the one hand, this can reduce the direct static load transmitted to the base crossbeam by the support frame fixedly connected on the longitudinal beam. On the other hand, it can weaken the mutual influence between the mechanical vibration or wind-induced vibration generated during the operation of the conveying mechanism and the wind-induced vibration of the cable-stayed bridge deck, prevent resonance, and improve the safety of the system.
[0016] In one optional embodiment, the support includes: an anchor post adapted to be fixedly connected to the foundation; a fixing frame including a main rod assembly and a strut assembly, the main rod assembly forming a tetrahedral structure, the bottom surface of the tetrahedral structure being fixed to the upper end of the anchor post, and each of the two vertices of the bottom surface of the tetrahedral structure near the cable assembly being connected to a stabilizing cable, and the top end of the tetrahedral structure being connected to the crossbeam cable; the strut assembly including four struts, the first end of each strut being connected to a vertex of the tetrahedral structure, and the second ends of each strut intersecting at a point inside the tetrahedral structure; and a ground anchor beam, arranged along the width direction and fixedly connected to the anchor post, the ground anchor beam including a first ground anchor beam and a second ground anchor beam, along the extension direction of the cable, the first ground anchor beam being located on the side near the cable assembly, and the second ground anchor beam being located on the side away from the cable assembly and located at the top of the anchor post, the bridge deck cable being connected to the first ground anchor beam, and the fixing frame being fixedly connected to the second ground anchor beam.
[0017] Beneficial effects: The anchor posts, fixing frames, and ground anchor beams are fixedly connected to each other, forming a stable support structure. The anchor posts are fixedly connected to the foundation, ensuring the stability of the connection between the support structure and the foundation. The tetrahedral main rod assembly forms the basic framework of the fixing frame. The tetrahedral structure is stable and has high strength. The strut assembly is supported inside the tetrahedral structural frame, further enhancing the strength and stability of the fixing frame, thus ensuring that the fixing frame can provide reliable support for the crossarm and stabilizing cables. The ground anchor beam is fixedly connected to the anchor posts, which on the one hand enhances the strength and stability of the anchor posts, and on the other hand provides stable support for the bridge deck cables. Thus, the entire support structure connects and supports the cable assembly, ensuring the stability of the cable assembly connection and bearing the load transmitted from the cable assembly, improving the reliability of the cable belt conveyor system.
[0018] In one optional embodiment, the fixing frame further includes: a web member assembly comprising six web members, each web member being connected between a support rod and a main rod on the bottom surface of the tetrahedral structure, the six web members being connected end to end in sequence to form a hexagonal structure; and corner braces, the corner braces being disposed near the vertices of the tetrahedral structure and connecting two adjacent main rods.
[0019] Beneficial effects: By setting web members as supports between the struts and the main rods, the deformation of the struts and the main rods is reduced. The hexagonal structure formed by the six web members has good stability and is not easily deformed, ensuring the fixation of the relative positions between the struts and the main rods. By setting corner braces near the vertices of the tetrahedral structure to support the two adjacent main rods, the structural strength at the vertices of the fixing frame is strengthened, thereby further enhancing the stability of the fixing frame and improving the reliability of the system.
[0020] In one optional embodiment, the cable assembly further includes: a crossarm cable, which is formed by the crossarm cable passing over the top of the fixed frame and extending downward at an incline, with one end of the crossarm cable away from the fixed frame being fixedly connected to the anchor post; a stabilizing cable, which is formed by the stabilizing cable passing over the top of the fixed frame and extending downward at an incline, with one end of the stabilizing cable away from the fixed frame being adapted to be fixedly connected to the foundation; and a bridge deck cable, which is formed by the bridge deck cable passing over the second ground anchor beam and extending downward at an incline, with one end of the bridge deck cable away from the second ground anchor beam being adapted to be fixedly connected to the foundation.
[0021] Beneficial effects: The top of the fixed frame serves as the turning support point for the crossarm cable, the top of the bottom surface of the fixed frame serves as the turning support point for the stabilizing cable, and the second ground anchor beam serves as the turning support point for the bridge deck cable. By setting up a fixed connection between the crossarm cable and the anchor post, a fixed connection between the crossarm cable and the anchor post is achieved, thereby achieving a fixed connection between the crossarm cable and the foundation. At the same time, by setting up a fixed connection between the stabilizing cable and the foundation, a fixed connection between the stabilizing cable and the foundation is achieved. By setting up a fixed connection between the bridge deck cable and the foundation, a fixed connection between the bridge deck cable and the foundation is achieved, thereby achieving a fixed connection between the suspender cable assembly and the foundation. This provides sufficient tension to the suspender cable, ensuring that the suspender cable is in a stable tensioned state, and thus provides a stable force for the support assembly and the conveying mechanism, ensuring the stability of the suspender cable conveyor system.
[0022] In one optional embodiment, the sling conveyor system further includes: a plurality of cable steering joints, the number of which is equal to and corresponds one-to-one with the number of slings, the cable steering joints being fixed to the support to fix the slings and change the extension direction of the slings.
[0023] Beneficial effects: The cable steering knuckle can fix the relative position of the sling and the support, ensuring a stable connection of the sling to the support and preventing it from detaching from the support. It can also be used to change the extension direction of the sling so that the sling tilts downward, thus facilitating connection with the foundation and making it easy to use.

Detailed Implementation
[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0041] Belt conveyor systems can transport materials along a specific conveyor line, forming a material transport process from the initial feeding point to the final unloading point. They can transport both loose materials and packaged items.
[0042] The following is combined Figures 1 to 13 The following describes embodiments of the present invention.
[0043] According to an embodiment of the present invention, a sling conveyor system is provided, comprising: at least two support parts 1, a sling assembly, a plurality of support components 3, and a conveying mechanism 4. The sling assembly is connected between two adjacent support parts 1 and includes multiple slings arranged in parallel. The plurality of support components 3 are connected to the sling assembly and are spaced apart along the extension direction of the slings. Each support component 3 includes a base beam 301 and a plurality of tie rods. The base beam 301 is horizontally arranged and perpendicular to the extension direction of the slings. Each tie rod is connected between two adjacent slings or between the base beam 301 and a sling, forming a polygonal frame perpendicular to the extension direction of the slings. The conveying mechanism 4 extends along the extension direction of the slings and is located within the accommodating space enclosed by the sling assembly and the support components 3 and is supported by the base beam 301.
[0044] The sling conveyor system of this embodiment connects and supports the sling assembly by setting a support part 1, and the support part 3 is connected to the sling assembly. The conveyor mechanism 4 is set in the accommodating space enclosed by the sling assembly and the support part 3, thus forming an integrated conveyor system with a simple structure. The polygonal frame formed by the support part 3 has good support capacity. The support part 3 and the sling assembly are interconnected and support each other to form a stable structural system. At the same time, the base beam 301 can provide stable support for the conveyor mechanism 4, which improves the stability of the entire system. Furthermore, the sling is a flexible component with strong load-bearing capacity. The tie rod in the support part 3 has a simple structure, light weight, good flexibility and high strength. Therefore, the support structure formed by the sling assembly and the support part 3 has a simple construction, light weight and strong overall rigidity, thus having a strong spanning capacity. It is suitable for large-span scenarios such as valleys with complex terrain or wide rivers, with a wide range of applications and low construction cost.
[0045] It should be noted that the extension direction of the cable is the same as the extension direction of the conveyor belt system. The support part 1 is fixed on the foundation, and the sling assembly and support assembly 3 are preferably connected to the top of the support part 1. Preferably, there are two support parts 1, and the sling assembly is connected between the two support parts 1. Of course, three or more support parts 1 can be set according to the site conditions. The foundation can be a horizontal ground, a hillside, a rock, etc. One end of each tie rod of the support assembly 3 is connected to a sling and the other end is connected to another sling or the base beam 301. The sling assembly is used to install and fix the support assembly 3. At the same time, the polygonal frame formed by the support assembly 3 also restricts the relative position between the slings. The slings and the support assembly 3 restrain and support each other, forming a stable flexible system. The slings are generally made of high-strength materials. Compared with traditional steel structures, the sling assembly has the advantages of light weight, strong spanning capacity, high load-bearing capacity, and reasonable stress distribution.
[0046] Preferably, the base beam 301 is made of H-beam steel, which has high strength, good stability and is readily available; the tie rod is made of steel, which has high strength and good stability.
[0047] In one embodiment, the sling assembly includes: a crossarm cable 201, a stabilizing cable 202, and a bridge deck cable 203. The crossarm cable 201 is positioned at the top of the sling conveyor system; the stabilizing cable 202 is located below the crossarm cable 201, and there are two stabilizing cables 202, positioned on either side of the sling conveyor system along its width; the bridge deck cable 203 is located below the stabilizing cable 202 to support the base beam 301. The base beam 301, the conveying mechanism 4, and other components mounted on the base beam 301 constitute the bridge deck of the entire system. The crossarm cable 201 and bridge deck cable 203 act as load-bearing components to support the weight of the bridge deck. The stabilizing cables 202 on both sides serve to bear the lateral wind load of the entire bridge deck system and, through the support assembly 3, form a polygonal system with the crossarm cable 201 and bridge deck cable 203 to stably support the conveying mechanism 4 and improve the system's stability. Here, "top" refers to the section along the width of the sling conveyor system. Figure 1 The middle arrow points to the end in the direction of "up"; "down" refers to the end in that direction. Figure 1 The direction indicated by the middle arrow is "down"; the width direction refers to... Figure 1 The middle arrow points to the "width direction".
[0048] Specifically, the crossarm cable 201, the stabilizing cable 202, and the bridge deck cable 203 are all connected to the support part 1. The crossarm cable 201 is connected to the top of the support part 1, and the distance between the two bridge deck cables 203 is less than the distance between the two stabilizing cables 202.
[0049] In one embodiment, the multiple tie rods include two first tie rods 302 and two second tie rods 303. The first tie rods 302 are connected between the crossbeam 201 and the stabilizing cable 202, and the second tie rods 303 are connected between the stabilizing cable 202 and the base beam 301. The base beam 301, the two first tie rods 302 and the two second tie rods 303 form a pentagonal frame perpendicular to the extension direction of the sling. The first tie rod 302 fixes the relative distance between the crossarm cable 201 and the stabilizing cable 202, and the second tie rod 303 fixes the relative distance between the stabilizing cable 202 and the base beam 301. At the same time, the base beam 301 is fixed on the bridge deck cable 203, thereby realizing the relative support and fixation between the cable assembly and the support assembly 3. The pentagonal frame formed by the support assembly 3 has good stability and good torsional resistance. The stabilizing cable 202, through the tie rod and the base beam 301, together with the crossarm cable 201 and the bridge deck cable 203, forms a torsional stabilization system with a pentagonal cross section, which improves the torsional resistance of the cable belt conveyor system, thereby improving the stability of the system and reducing the impact of lateral wind load.
[0050] Specifically, one end of the first tie rod 302 is connected to the crossbeam 201 and the other end is connected to a stabilizing cable 202; one end of the second tie rod 303 is connected to a stabilizing cable 202 and the other end is connected to the end of the base beam 301 near the stabilizing cable 202; the support assembly 3 is arranged in a pentagonal frame with the first tie rod 302, the second tie rod 303, the base beam 301, the second tie rod 303, and the first tie rod 302 connected end to end in sequence; two first tie rods 302 are connected to the crossbeam 201 at the same time, and one first tie rod 302 and one second tie rod 303 are connected to a stabilizing cable 202 at the same time.
[0051] In one embodiment, the conveying mechanism 4 includes a support frame, a roller frame, a roller assembly, and a conveyor belt 407. The support frame is connected to the base beam 301; the roller frame is fixed to the support frame, and the roller assembly is rotatably mounted on the roller frame; the conveyor belt 407 is mounted on the roller assembly and rolls in contact with the roller assembly, and the conveyor belt 407 is adapted to move along the extension direction of the sling. The support frame supports the roller frame, the roller frame supports the roller assembly, and the roller assembly supports the conveyor belt 407, thus providing support for the conveyor belt 407. Furthermore, the rolling contact between the conveyor belt 407 and the roller assembly reduces the friction during the conveyor belt 407's operation, thereby reducing the driving force required to move the conveyor belt 407, thus reducing energy consumption and cost. It should be noted that the conveying mechanism 4 includes a carrying section 410 and a return section 420. The carrying section 410 and the return section 420 extend in parallel directions but move in opposite directions. The belt 407 carries the material 409 and runs continuously on the idlers on the idler frame. The idlers are preferably rubber idlers. The idler assembly includes at least two idlers, and the axis of the idlers is perpendicular to the moving direction of the belt 407.
[0052] Specifically, the support frame includes support columns 401 and support beams 402. The support columns 401 are positioned above and connected to the base beams 301. Each base beam 301 has two support columns 401, spaced apart along its width. The support beams 402 are positioned between the two support columns 401 and fixedly connected to them. There are two support beams 402, spaced apart vertically. The overall structure of the support frame is a portal frame. The idler frame includes a first idler frame 403 and a second idler frame 404. The first idler frame 403 is fixedly mounted on the upper support beam 402, and the second idler frame 404 is fixedly mounted on the lower support beam 402. The idler assembly includes a first idler assembly 405 and a second idler assembly 406. The first idler assembly 405 is disposed on a first idler frame 403, and the second idler assembly 406 is disposed on a second idler frame 404. Both the first idler assembly 405 and the second idler assembly 406 support a conveyor belt 407.
[0053] Preferably, the roller frame is made of bent steel plate and is fixed to the support beam 402 by bolts. The support beam 402 is fixed to the support column 401 by welding or bolts.
[0054] Preferably, the carrying section 410 is located above the return section 420, the conveyor belt 407 supported on the first idler assembly 405 is the carrying section 410, and the conveyor belt 407 supported on the second idler assembly 406 is the return section 420. The conveyor belt 407 can also be replaced by a belt.
[0055] Preferably, the first idler frame 403 is a triangular idler frame, and the carrying section 410 is supported by the triangular idler frame; the second idler frame 404 is a bilateral idler frame, and the return section 420 is supported by the bilateral idler frame.
[0056] Preferably, a rain cover 408 is provided above the support frame. The rain cover 408 extends along the extension direction of the tape 407 to cover the tape 407 and the material 409 on it, so as to prevent the material 409 from getting wet by rain or splashing.
[0057] In one embodiment, the sling conveyor system further includes a longitudinal beam 5, which is parallel to the sling and mounted on a base crossbeam 301. A support frame is mounted on the longitudinal beam 5. The base crossbeam 301 supports the longitudinal beam 5, which in turn provides support to the support frame. The support columns 401 of the support frame are indirectly connected to the base crossbeam 301 via the longitudinal beam 5, thus providing support force to the support frame with good stability. Furthermore, since the extension direction of the longitudinal beam 5 is the same as and continuous with the extension direction of the sling conveyor system, the spacing between adjacent support frames can be arbitrarily customized according to the requirements of the sling conveyor system, offering high flexibility. It should be noted that the load of the conveying mechanism 4 is applied to the longitudinal beam 5 through the support columns 401. Preferably, the support frame is evenly distributed along the extension direction of the sling conveyor system to ensure uniform stress on the longitudinal beam 5, thereby achieving coordination and coupling of the sling bridge deck deformation and ensuring the safe operation of the conveyor belt 407.
[0058] Specifically, the extension direction of the longitudinal beam 5 is perpendicular to the axis of the base beam 301 and the axis of the support beam 402 in the support frame.
[0059] Preferably, the longitudinal beam 5 is a box beam, which has high structural stability and is suitable for supporting other components.
[0060] In one embodiment, the sling conveyor system further includes a fixed connector 601 and an elastic connector 602. The fixed connector 601 is fixed to the base crossbeam 301, and the elastic connector 602 passes through the fixed connector 601 and the longitudinal beam 5 in sequence to connect the fixed connector 601 and the longitudinal beam 5. The fixed connector 601 is fixedly connected to the base crossbeam 301 and to the longitudinal beam 5, thus achieving the connection between the longitudinal beam 5 and the base crossbeam 301. Furthermore, the longitudinal beam 5 and the fixed connector 601 are elastically connected through the elastic connector 602, achieving an indirect elastic connection between the longitudinal beam 5 and the base crossbeam 301. This reduces the direct static load transmitted from the support frame fixedly connected to the longitudinal beam 5 to the base crossbeam 301, and also weakens the interaction between the mechanical vibration or wind-induced vibration generated during the operation of the conveyor mechanism 4 and the wind-induced vibration of the sling bridge deck, preventing resonance and improving the safety of the system.
[0061] Specifically, the longitudinal beam 5 is a box beam, and the fixed connector 601 is an angle steel connector. Along the width direction, one angle steel connector is provided on each side of the box beam. The short leg of the angle steel connector is welded to the base crossbeam 301, and the long leg is connected to the longitudinal beam 5 via an elastic connector 602. Preferably, the elastic connector 602 is a damping spring. Damping springs have a simple structure, good damping effect, and are inexpensive.
[0062] It should be noted that the sling assembly, support assembly, and conveyor mechanism 4 are all suspended in the air. The main lateral load borne by the entire system is the wind load perpendicular to the running direction of the conveyor belt 407. The conveyor mechanism 4, which is suspended in the air, is extremely sensitive to wind loads, especially in canyon and river areas, where it is greatly affected by canyon winds. Structural wind vibration safety is one of the most important aspects of belt conveyor system engineering. Traditional belt conveyor systems, when crossing wide valleys or rivers, generally use wind-resistant suspension systems with a large angle to the horizontal plane or truss structures with high rigidity to ensure that the conveyor mechanism can withstand wind loads. However, due to terrain and other reasons, the arrangement of wind-resistant cables and truss structures is difficult. In contrast, the sling belt conveyor system of this embodiment not only has a large span, but also has a simple structure, is safe and reliable, easy to implement, and has low construction costs.
[0063] In one embodiment, the support 1 includes: an anchor post 110, a fixing frame 120, and a ground anchor beam. The anchor post 110 is adapted to be fixedly connected to the foundation; the fixing frame 120 includes a main rod assembly and a strut assembly. The main rod assembly forms a tetrahedral structure, the bottom surface of which is fixed to the upper end of the anchor post 110, and each of the two vertices near the cable assembly on the bottom surface of the tetrahedral structure is connected to a stabilizing cable 202, and the top of the tetrahedral structure is connected to a crossbeam cable 201; the strut assembly includes four struts 122, the first end of each strut 122 being connected to a vertex of the tetrahedral structure, and each strut 122... The second end intersects at a point inside the tetrahedral structure; the ground anchor beam is set along the width direction and fixedly connected to the anchor post 110. The ground anchor beam includes a first ground anchor beam 131 and a second ground anchor beam 132. Along the extension direction of the suspender cable, the first ground anchor beam 131 is set on the side close to the suspender cable assembly, and the second ground anchor beam 132 is set on the side away from the suspender cable assembly and located at the top of the anchor post 110. The bridge deck cable 203 is connected to the first ground anchor beam 131, and the fixing frame 120 is fixedly connected to the second ground anchor beam 132. Anchor posts 110, fixing frames 120, and ground anchor beams are fixedly connected to each other, forming a structurally stable support part 1. The anchor posts 110 are fixedly connected to the foundation, ensuring the stability of the connection between the support part 1 and the foundation. The tetrahedral main rod assembly forms the basic frame of the fixing frame 120. The tetrahedral structure is stable and has high strength. The strut assembly is supported inside the tetrahedral frame, further strengthening the strength and stability of the fixing frame 120, thus ensuring that the fixing frame 120 can provide reliable support for the crossarm cable 201 and the stabilizing cable 202. The ground anchor beam is fixedly connected to the anchor posts 110, strengthening the strength and stability of the anchor posts 110 and providing stable support for the bridge deck cable 203. This achieves the connection and support of the entire support part 1 for the cable assembly, ensuring the stability of the cable assembly connection and bearing the load transmitted from the cable assembly, thus improving the reliability of the cable belt conveyor system. Here, "top" and "upper end" both refer to the section along... Figure 1 The middle arrow points to the end in the direction of "up"; the base of the tetrahedron refers to the side along... Figure 1 The side facing the direction indicated by the middle arrow "down". When the sling conveyor system is set in a valley or river, the fixing frame 120 is set on both sides of the valley or river.
[0064] Specifically, the fixing frame 120 is fixedly connected to the foundation via anchor posts 110, and the anchor posts 110 are integrated with the ground anchor beam to provide stable support for the slings. For example... Figure 3 As shown, in a cross-section perpendicular to the extension direction of the sling, the cross-section of the fixing frame 120 is similar to the cross-section formed by the crossbeam 201 and the stabilizing cable 202, exhibiting a tripod structure with good stability. The main rod assembly and the strut assembly in the fixing frame 120 form a stable support system, improving the reliability of the support connection between the support part 1 and the sling assembly, and enhancing the load-bearing capacity of the support part 1.
[0065] In one embodiment, the fixing frame 120 further includes a web member assembly and corner braces 124. The web member assembly includes six web members 123, each web member 123 connected between a support rod 122 and a main rod 121 on the bottom surface of the tetrahedral structure. The six web members 123 are connected end to end to form a hexagonal structure. The corner braces 124 are located near the vertices of the tetrahedral structure and connect adjacent main rods 121. By setting web members 123 between the support rods 122 and the main rods 121 as supports, the deformation of the support rods 122 and the main rods 121 is reduced. The hexagonal structure formed by the six web members 123 has good stability and is not easily deformed, ensuring the fixation of the relative positions between the support rods 122 and the main rods 121. By setting corner braces 124 near the vertices of the tetrahedral structure to support adjacent main rods 121, the structural strength at the vertices of the fixing frame 120 is strengthened, thereby further enhancing the stability of the fixing frame 120 and improving the reliability of the system. Specifically, one end of the web member 123 is fixedly connected to a support rod 122 and the other end is fixedly connected to a main rod 121.
[0066] Preferably, the fixing frame 120 further includes a connecting rod 125. One end of the connecting rod 125 is fixedly connected to the main rod 121 except for the main rod 121 on the bottom surface of the tetrahedron, and the other end is fixedly connected to the intersection of the second ends of each support rod 122 inside the tetrahedron structure, thereby providing support between the main rod 121 and the support rod 122, further strengthening the structural strength of the upper part of the fixing frame 120 and enhancing the stability of the fixing frame 120.
[0067] In one embodiment, the cable assembly further includes: a crossarm cable 204, a stabilizing cable 205, and a bridge deck cable 206. The crossarm cable 204 is formed by the crossarm cable 201 passing over the top of the fixed frame 120 and extending downward at an incline, with one end of the crossarm cable 204 away from the fixed frame 120 fixedly connected to the anchor post 110; the stabilizing cable 205 is formed by the stabilizing cable 202 passing over the top of the fixed frame 120 and extending downward at an incline, with one end of the stabilizing cable 205 away from the fixed frame 120 adapted to be fixedly connected to the foundation; the bridge deck cable 206 is formed by the bridge deck cable 203 passing over the second ground anchor beam 132 and extending downward at an incline, with one end of the bridge deck cable 206 away from the second ground anchor beam 132 adapted to be fixedly connected to the foundation. The top of the fixed frame 120 serves as the turning support point for the crossarm cable 201, the top of the bottom surface of the fixed frame 120 serves as the turning support point for the stabilizing cable 202, and the second ground anchor beam 132 serves as the turning support point for the bridge deck cable 203. By setting the crossarm cable 204 to be fixedly connected to the anchor post 110, the crossarm cable 201 and the anchor post 110 are fixedly connected, thereby achieving a fixed connection between the crossarm cable 201 and the foundation. At the same time, by setting the stabilizing cable 205 to be fixedly connected to the foundation, the stabilizing cable 202 and the foundation are fixedly connected. By setting the bridge deck cable 206 to be fixedly connected to the foundation, the bridge deck cable 203 and the foundation are fixedly connected, thereby achieving a fixed connection between the cable assembly and the foundation. This provides sufficient tension to the cable, ensuring that the cable is in a stable tensioned state, and thus provides a stable force to the support assembly 3 and the conveying mechanism 4, ensuring the stability of the cable belt conveyor system.
[0068] Preferably, the crossarm stay cable 204 is anchored to the anchor post 110, the stabilizing stay cable 205 is anchored to the foundation, and the bridge deck stay cable 206 is anchored to the foundation using anchors 140. This anchoring method provides high reliability and strong load-bearing capacity. When the cable-stayed conveyor system is used in a valley, the stabilizing stay cable 205 and the bridge deck stay cable 206 are anchored to the slopes on both sides of the valley.
[0069] Preferably, the crossbeam cable 201 is split into two strands after passing over the top of the fixed frame 120, forming two crossbeam stay cables 204, and the two crossbeam stay cables 204 are respectively anchored to an anchor post 110.
[0070] In one embodiment, the sling conveyor system further includes a plurality of cable steering joints 7, the number of which is equal to and corresponds one-to-one with the number of slings. The cable steering joints 7 are fixed to the support portion 1 to secure the slings and change their extension direction. The cable steering joints 7 fix the relative position of the slings to the support portion 1, ensuring a stable connection between the slings and the support portion 1 and preventing them from detaching from the support portion 1. They also change the extension direction of the slings, causing them to tilt downwards for easier connection to the foundation and convenient use.
[0071] Specifically, a cable steering joint 7 is provided at the top of the fixed frame 120. After passing through the cable steering joint 7, the crossarm cable 201 tilts downward to form a crossarm stay cable 204, which is anchored to the top of the anchor post 110. On the bottom surface of the fixed frame 120, a cable steering joint 7 is provided at each of the two vertices near the stabilizing cable 202. Each stabilizing cable 202 is connected to a cable steering joint 7. After passing through the cable steering joint 7, the stabilizing cable 202 tilts downward to form a stabilizing stay cable 205, which is anchored in the rock foundation 902 behind the third ground anchor beam 133. The anchor 140 used for anchoring is located below the ground line 901. Two cable steering joints 7 are provided on the first ground anchor beam 131. Each bridge deck cable 203 is connected to a cable steering joint 7. After passing through the cable steering joint 7, the bridge deck cable 203 tilts downward to form a bridge deck stay cable 206, which is anchored in the rock foundation 902 behind the first ground anchor beam 131.
[0072] Specifically, the cable steering knuckle 7 includes a fixing plate 701 and a limiting plate 702. The fixing plate 701 is fixedly connected to the support part 1, and the limiting plate 702 is fixedly connected above the fixing plate 701. There are two limiting plates 702, which are spaced apart along the width direction. The sling is clamped between the two limiting plates 702 to limit the sling along the width direction and prevent the sling from jumping off.
[0073] Preferably, the fixing plate 701 is constructed as an upwardly convex arc-shaped plate to facilitate the turning of the sling, ensure the smoothness of the sling turning, and reduce wear on the sling; the limiting plate 702 is constructed with a stiffening plate 703 to strengthen the structural strength of the limiting plate 702 and improve the reliability of the cable turning joint 7.
[0074] In one embodiment, the sling conveyor system further includes a walkway 801, which extends along the extension direction of the sling and is disposed on the base beam 301 and located on both sides of the conveyor mechanism 4 in the width direction, so as to facilitate inspection by the staff.
[0075] In one embodiment, the sling conveyor system further includes guardrails 802, which are arranged at both ends of the base beam 301 along the width direction to protect the walkway 801 and ensure the safety of the staff.
[0076] The sling-type conveyor system of this embodiment forms a pentagonal anti-torsional system by connecting crossbeams 201, stabilizing cables 202, bridge deck cables 203, tie rods, and base beams 301. The support sections 1 at both ends enable the sling-type conveyor system to resist horizontal wind loads and improve the lateral and vertical bearing capacity of the structure, providing a new way to solve the wind resistance safety problem of belt conveyor systems in canyon terrain conditions. The sling-type conveyor system, composed of conveyor belts 407, portal frame, base beams 301, prestressed slings, anchoring devices, and other components, enables the belt conveyor system to cross large-span valleys and rivers. The sling-type conveyor system can cross areas with complex terrain or where it is inconvenient or impossible to construct support sections 1. It is safe, reliable, simple in construction, and easy to implement. It avoids the use of more steel legs and foundations, thus avoiding damage to the mountain ecological environment. It is a green material conveying system that reduces upfront project investment, has low maintenance costs during operation, and improves the economic benefits of the project.
