Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and more specifically to a tubular belt conveyor system. Background Technology

[0002] Pipe belt conveyors rely on friction to drive the conveyor belt, which is then forced into a cylindrical shape by spaced regular polygonal (usually hexagonal) idler rollers to transport materials. As exploitable resources continue to decrease and mining sites gradually expand underground or to high-altitude mountain areas, pipe belt conveyors are mainly used in long-span conveying projects.

[0003] Currently, conveyor belt conveyors typically employ a spatial truss system composed of steel structural members. The cross-section of this truss system is usually rectangular to support the conveyor belt. However, the steel structural truss involves a large number of steel members, resulting in a complex structure and significant weight. Consequently, it presents significant challenges for workers, including high labor intensity and difficult installation and operation. Summary of the Invention

[0004] In view of this, the present invention provides a tubular conveyor system to solve the problem of complex and heavy steel truss structure of tubular conveyor systems.

[0005] In a first aspect, the present invention provides a conveyor system comprising: at least two support sections; a cable assembly connected to the at least two support sections, the cable assembly comprising multiple cables arranged in parallel; several sets of support rod assemblies spaced apart along the extension direction of the cables, each set of support rod assemblies comprising multiple support rods connected end to end in sequence, each support rod being connected between two adjacent cables, each support rod being connected to a roller, the roller being rotatable relative to the support rod, the rollers on the multiple support rods forming an accommodating space; and a conveyor belt extending along the extension direction of the cables and located within the accommodating space formed by the rollers.

[0006] Beneficial effects: By connecting several strut assemblies to the cable assembly to form a flexible system to support the conveyor belt, the cables and struts support each other, resulting in a stable structure. The combination of cables and struts is simple in structure, lightweight, and has a high load-bearing capacity, making the entire system more capable of crossing. Furthermore, by directly installing idlers on the struts, the traditional PSK plate is eliminated, simplifying assembly, facilitating construction, reducing the amount of steel used in the entire system, further reducing the overall weight, decreasing the load on the support components, and extending the service life.

[0007] In one optional embodiment, the cable assembly includes: an upper stabilizing cable; a lower stabilizing cable connected to the support and located below the upper stabilizing cable; and two load-bearing cables connected to the support, the two load-bearing cables being located between the upper stabilizing cable and the lower stabilizing cable, and the two load-bearing cables being located on both sides of the line connecting the upper stabilizing cable and the lower stabilizing cable, so that the cross-section of the cable assembly is quadrilateral.

[0008] Beneficial effects: The cable assembly consists of four cables located at the four vertices of a quadrilateral. The quadrilateral structure is simple, requires fewer cables, is easy to lay out, and can achieve stable support.

[0009] In one optional embodiment, the strut assembly includes four struts, including two first struts and two second struts. One end of each first strut is connected to the upper stabilizing cable and the other end is connected to a load-bearing cable. One end of each second strut is connected to the lower stabilizing cable and the other end is connected to a load-bearing cable.

[0010] Beneficial effects: The first strut connects the upper stabilizing cable and the load-bearing cable, fixing their relative positions and transferring the force on the upper stabilizing cable to the load-bearing cable. The second strut connects the lower stabilizing cable and the load-bearing cable, fixing their relative positions and transferring the force on the lower stabilizing cable to the load-bearing cable. Thus, the upper and lower stabilizing cables are fixed through the load-bearing cable and strut assembly, and the force on the upper and lower stabilizing cables is transferred to the support, improving the stability of the cable assembly and strut assembly.

[0011] In one optional embodiment, the conveyor belt includes a carrying section and a return section with opposite conveying directions; two load-bearing cables are connected by a connecting plate, and idlers are provided on the upper and lower sides of the connecting plate. The idlers above the connecting plate and the idlers on the two first support rods form a first accommodating space to accommodate and support the carrying section, and the idlers below the connecting plate and the idlers on the two second support rods form a second accommodating space to accommodate and support the return section.

[0012] Beneficial effects: The conveyor belt is supported by a triangular flexible structure system consisting of cable assemblies, strut assemblies, and connecting plates. The structure is stable and the stress is reasonable. Furthermore, by directly installing idlers on the struts and connecting plates, the weight can be further reduced, materials can be saved, and construction difficulty can be reduced. The rolling contact between the conveyor belt and the idlers can also reduce friction, energy consumption, and costs.

[0013] In one optional embodiment, the conveyor system further includes a cable clamp, the cable clamp having a through portion and two connecting portions, the connecting portions being connected to the outside of the through portion and the two connecting portions being arranged at an included angle, a cable passing through the through portion, and each connecting portion being connected to a support rod.

[0014] Beneficial effects: By threading a cable through the through part of the cable clamp and connecting each connection part to a strut, a cable and two struts are simultaneously connected to the same cable clamp, a stable connection between the cable and the struts is achieved, thereby ensuring the reliability of the connection between the strut assembly and the cable assembly and ensuring the stability of the entire system. Furthermore, the two connection parts are set at an angle, which can ensure that the angle between the two struts connected to the same cable remains unchanged, further ensuring the stability of the triangular system.

[0015] In one optional embodiment, the conveyor system further includes: an anchor clamp, the anchor clamp being U-shaped, the anchor clamp including two oppositely arranged side plates and a base plate connecting the two side plates, the base plate having a first connecting hole for the support rod to pass through; the side plates having a second connecting hole, and the connecting part having a third connecting hole, the second connecting hole and the third connecting hole being connected by a first connector to connect the anchor clamp and the cable clamp.

[0016] Beneficial effects: By setting the side plate and the connecting part to be connected through the first connecting piece, the anchor clamp and the cable clamp are fixedly connected. The anchor clamp and the support rod are connected by passing through the first connecting hole on the bottom plate. Thus, through the cooperation of the anchor clamp and the cable clamp, the support rod and the cable are stably connected. The connection is stable, easy to operate and low in cost.

[0017] In one optional embodiment, the conveyor system further includes: a walkway support member, the axis of which is perpendicular to the extension direction of the cable, the walkway support member being fixedly connected to the cable clamp on the lower stabilizing cable, and the walkway support member being provided with a walkway extending along the extension direction of the cable.

[0018] Beneficial effects: By setting up a fixed connection between the walkway support and the cable clamp on the lower stabilizing cable, the connection between the walkway support and the lower stabilizing cable is realized. The lower stabilizing cable provides force to the walkway support, ensuring the stability of the walkway support, and thus ensuring the stability of the walkway set on the walkway support.

[0019] In one optional embodiment, the conveyor system further includes a support base, which is fixedly connected to the support portion, and the load-bearing cable is connected to the support base.

[0020] Beneficial effects: By fixing a support seat on the support part and connecting the load-bearing cable through the support seat, a fixed connection between the load-bearing cable and the support part is achieved. The support seat has good stability and high connection reliability, ensuring stable support of the load-bearing cable by the support part and improving the stability of the system.

[0021] In one alternative embodiment, the conveyor system further includes an anchor fixedly connected to the support and corresponding to the lower stabilizing cable to connect the lower stabilizing cable to the support.

[0022] Beneficial effects: By connecting the anchors set on the support to the lower stabilizing cable, the lower stabilizing cable is fixed on the support. The support provides tension to the lower stabilizing cable, and the force on the lower stabilizing cable is transmitted to the support through the anchors, keeping the lower stabilizing cable fixed in position and stable under force, thereby ensuring the structural stability of the flexible system composed of the cable assembly and the strut assembly.

[0023] In one alternative embodiment, the conveyor system further includes a photovoltaic module, the photovoltaic module comprising a photovoltaic panel disposed around the outside of the strut assembly.

[0024] Beneficial effects: The photovoltaic panels are installed on the outside of the support rod assembly to form a closed structure, which prevents materials on the conveyor belt from flying into the surrounding environment, thus meeting environmental protection requirements. In addition, the photovoltaic panels can also be used to convert solar energy into electrical energy. The electrical energy is connected to the circuit of the conveyor system through the circuit components of the photovoltaic modules, providing power for the operation of the conveyor system through photovoltaic power generation, saving additional enclosure color panels.

Detailed Implementation

[0048] 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.

[0049] Traditional conveyor belt systems typically employ a spatial truss system composed of steel structural members. PSK (Platelet-Style Kilted Frame) panels are installed on the steel truss as a supporting structure to support the conveyor belt. These PSK panels are made of spliced ​​angle steel or stamped steel plates. Figure 1As shown, the PSK plate 10 of the tubular conveyor system has a rectangular plate structure with two holes suitable for threading the tubular conveyor belt. Six idlers 310 are arranged circumferentially around each hole on the PSK plate, and the space enclosed by the six idlers 310 is used to accommodate and support the tubular conveyor belt. Traditional tubular conveyor trestle bridges require extensive on-site splicing of steel structural members during construction. After the main truss is assembled, the maintenance structure is installed, making the process cumbersome and inefficient. The aforementioned conveyor belt system has the following problems: The PSK plates are spliced ​​from angle steel or integrally stamped from steel plates, resulting in complex construction processes, numerous components, long construction periods, large personnel requirements, and difficulty in cost control; the number of 310 idlers is large, requiring 12 310 idlers per PSK plate, leading to high prices; the spanning capacity is limited, with a maximum span of 30m for the small truss scheme and 90m for the large truss scheme, resulting in high costs, large steel consumption, heavy lifting weights, and significant construction difficulties and inconvenience; subsequent maintenance costs are high, as paint, belts, and idlers are consumables, and the more components there are, the higher the maintenance costs.

[0050] The following is combined Figures 2 to 20 The following describes embodiments of the present invention.

[0051] According to an embodiment of the present invention, a conveyor belt system is provided, comprising: at least two support parts 1, a cable assembly 2, a plurality of strut assemblies 3, and a conveyor belt. Specifically, the cable assembly 2 is connected to at least two support parts 1, and the cable assembly 2 includes multiple cables arranged in parallel; the plurality of strut assemblies 3 are spaced apart along the extension direction of the cables, each strut assembly 3 includes multiple struts connected end to end in sequence, each strut is connected between two adjacent cables, and idler rollers 310 are connected to the struts. The idler rollers 310 are rotatable relative to the struts, and the idler rollers 310 on the multiple struts form an accommodating space; the conveyor belt extends along the extension direction of the cables and is located in the accommodating space formed by the idler rollers 310.

[0052] The conveyor system of this embodiment uses a flexible system composed of several strut assemblies 3 connected to the cable assembly 2 to support the conveyor belt. The cables and struts support each other, resulting in a stable structure. The combination of cables and struts is simple in structure, lightweight, and has a high load-bearing capacity, making the entire system more capable of crossing. Furthermore, by directly installing idler rollers 310 on the struts, the traditional PSK plate is eliminated, simplifying assembly and construction. This also reduces the amount of steel used in the entire system, further reducing the overall weight, decreasing the load on the support part 1, and extending its service life.

[0053] It should be noted that the support part 1 is fixed to the ground, and the cable assembly 2 and the strut assembly 3 are preferably connected to the top of the support part 1. There are at least two support parts 1, and the cable assembly 2 is connected to at least two support parts 1. Specifically, the specific number of support parts 1 can be set according to the site conditions, and three or more support parts 1 can also be set. One end of each strut is connected to a cable and the other end is connected to another cable, that is, the strut is supported between two adjacent cables. The plane formed by the strut assembly 3 is perpendicular to the extension direction of the cable. The cable and the strut mutually restrain and support each other, forming a stable flexible system. The extension direction of the cable is the extension direction of the conveyor belt system. The cable structure is a structural system in which the cable is the main load-bearing component. The cable is generally made of high-strength material. Compared with the traditional steel structure, the cable structure has the advantages of saving materials, strong spanning capacity, light weight, and reasonable stress distribution. The load-bearing capacity of the cable material is higher, more than 5 times that of steel. Finished cables are easy to purchase, do not need to be painted, and have a long service life.

[0054] Specifically, the support unit 1 includes two support columns 101 and a support beam. The two support columns 101 are spaced apart along the width direction of the conveyor system. The support beam connects the two support columns 101, resulting in a stable structure and good support force. Here, the width direction refers to... Figure 5 The "width direction" indicated by the middle arrow is perpendicular to the extension direction of the conveyor belt system.

[0055] Specifically, the cable is a flexible component with a high load-bearing capacity. For example... Figure 20 As shown, the cable consists of high-strength steel wire 210, galvanized coating 220, inner sheath 230, outer sheath 240, and rubber 250 from the inside out. The inner sheath 230 and outer sheath 240 are made of high-density polyethylene (HDPE).

[0056] In one embodiment, the cable assembly 2 includes an upper stabilizing cable 201, a lower stabilizing cable 202, and two load-bearing cables 203. The lower stabilizing cable 202 is connected to the support portion 1 and located below the upper stabilizing cable 201; the two load-bearing cables 203 are connected to the support portion 1, located between the upper stabilizing cable 201 and the lower stabilizing cable 202, and respectively located on both sides of the line connecting the upper stabilizing cable 201 and the lower stabilizing cable 202, so that the cross-section of the cable assembly 2 is quadrilateral. The cable assembly 2 includes four cables, which are located at the four vertices of the quadrilateral. The quadrilateral structure is simple, requires fewer cables, is easy to arrange, and can achieve stable support. Preferably, the cross-section of the cable assembly 2 is rhomboid. Here, "upper" refers to... Figure 2 The middle arrow points in the direction of "up"; "down" refers to... Figure 2 The direction indicated by the middle arrow is "down".

[0057] Specifically, two load-bearing cables 203 are connected to the support part 1. After being connected to the support parts 1 located at both ends of the conveyor belt system, the load-bearing cables 203 extend downwards to the foundation surface and are anchored to the gravity anchor block 110. Furthermore, by applying a pre-tension to the load-bearing cables 203, the load-bearing cables 203 are fixed and tensioned, thereby ensuring the stability of the cable assembly 2. The lower stabilizing cable 202 is connected to the support part 1, which further improves the reliability of the connection between the cable assembly 2 and the support part 1 and improves the stability of the cable assembly. The upper stabilizing cable 201 is connected to the load-bearing cables 203 through the strut assembly 3, thereby fixing the upper stabilizing cable 201.

[0058] In one embodiment, the strut assembly 3 includes four struts, including two first struts 301 and two second struts 302. One end of each first strut 301 is connected to the upper stabilizing cable 201 and the other end is connected to a load-bearing cable 203. One end of each second strut 302 is connected to the lower stabilizing cable 202 and the other end is connected to a load-bearing cable 203. The first strut 301 connects the upper stabilizing cable 201 and the load-bearing cable 203, and is used to fix the relative position between the upper stabilizing cable 201 and the load-bearing cable 203, and to transfer the force on the upper stabilizing cable 201 to the load-bearing cable 203. The second strut 302 connects the lower stabilizing cable 202 and the load-bearing cable 203, and is used to fix the relative position between the lower stabilizing cable 202 and the load-bearing cable 203, and to transfer the force on the lower stabilizing cable 202 to the load-bearing cable 203. Thus, the upper stabilizing cable 201 and the lower stabilizing cable 202 are fixed by the load-bearing cable 203 and the strut assembly, and the force on the upper stabilizing cable 201 and the lower stabilizing cable 202 is transferred to the support part 1, thereby improving the stability of the cable assembly 2 and the strut assembly 3. It should be noted that the length of the strut is fixed. By connecting the strut between the two cables, the connection and support of the two cables are achieved, ensuring that the position of each cable in the cable assembly 2 remains unchanged, improving the stability of the structure. In addition, the strut is lightweight, which helps to reduce the overall weight of the conveyor belt system.

[0059] Specifically, the upper stabilizing cable 201 is connected to the load-bearing cable 203 via the first support rod 301. The internal force of the upper stabilizing cable 201 is transmitted to the load-bearing cable 203 through the support rod. Since the load-bearing cable 203 is stably connected to the support part 1, the upper stabilizing cable 201 can be fixed by the cooperation of the load-bearing cable 203 and the first support rod 301. After the upper stabilizing cable 201 is connected to the support rod assembly 3 located at both ends of the conveyor belt system, it extends downwards to the foundation surface and is anchored to the gravity anchor block 110, thus achieving the stabilization of the upper stabilizing cable. Further tightening and fixing of cable 201 improves the stability of cable assembly 2; the lower stabilizing cable 202 is connected to the load-bearing cable 203 through the second support rod 302, and both ends of the lower stabilizing cable 202 are connected to a support part 1 to ensure the stability of the lower stabilizing cable 202. Furthermore, when the number of support parts 1 is N, where N is greater than 2, the lower stabilizing cable 202 is divided into (N-1) segments, each segment is located between two adjacent support parts 1 and both ends of the segment are connected to a support part 1, where N is a positive integer greater than or equal to 2.

[0060] In one embodiment, the conveyor belt includes a carrying section 401 and a return section 402 with opposite conveying directions; two load-bearing cables 203 are connected by a connecting plate 530, and idlers 310 are provided on the upper and lower sides of the connecting plate 530. The idlers 310 above the connecting plate 530 and the idlers 310 on the two first support rods 301 form a first accommodating space to accommodate and support the carrying section 401, and the idlers 310 below the connecting plate 530 and the idlers 310 on the two second support rods 302 form a second accommodating space to accommodate and support the return section 402. By setting a connecting plate 530 between the two load-bearing cables 203, the connecting plate 530 and the two first support rods 301 are connected end to end to form a triangle, and the connecting plate 530 and the two second support rods 302 are connected end to end to form a triangle. That is, the connecting plate 530 divides the quadrilateral formed by the four support rods and four cables into two triangles, forming a stable triangular system. The triangular space formed between the two first support rods 301 and the connecting plate 530 accommodates the load-bearing section 401, and the triangular space formed between the two second support rods 302 and the connecting plate 530 accommodates the return section 402. The conveyor belt is supported by a triangular flexible structure system composed of the cable assembly 2, the support rod assembly 3, and the connecting plate 530. The structure is stable and the force is reasonable. Furthermore, by directly setting idler rollers 310 on the support rods and the connecting plate 530, the weight can be further reduced, materials can be saved, and construction difficulty can be reduced. The rolling contact between the conveyor belt and the idler rollers 310 can also reduce friction, reduce energy consumption, and reduce costs. It should be noted that the carrying section 401 and the return section 402 extend in parallel directions but move in opposite directions.

[0061] Preferably, the triangle formed by the connecting plate 530 and the two first support rods 301, and the triangle formed by the connecting plate 530 and the two second support rods 302 are symmetrical about the connecting plate 530, which has good stability and is easy to process. In this case, the quadrilateral formed by the four support rods connected end to end in sequence is a rhombus.

[0062] Preferably, the lengths of the connecting plate 530, the first support rod 301, and the second support rod 302 are all equal, so that the first triangle formed by the connecting plate 530 and the two first support rods 301, and the second triangle formed by the connecting plate 530 and the two second support rods 302, are both equilateral triangles. Figure 8 The interior angles θ1, θ2, and θ3 of the first triangle shown are all 60°, and the interior angles θ4, θ5, and θ6 of the second triangle are all 60°. Both the carrying section 401 and the return section 402 are cylindrical. The equilateral triangles exhibit good symmetry, resulting in more reasonable force distribution and better stability. It is understood that, as an alternative implementation, the length of the connecting plate 530 can also be unequal to the length of the support rod. The triangle is then isosceles, meaning θ2 and θ3 are equal but not equal to θ1, and θ5 and θ6 are equal but not equal to θ4. The specific design can be tailored to the requirements of the carrying section 401 and the return section 402. In this case, a triangular stable system can still be formed without affecting the stability of the conveyor system.

[0063] Preferably, the connecting plate 530 is a steel plate, which has high strength, good stability and is readily available.

[0064] Preferably, a roller 310 is provided on each of the upper and lower sides of the connecting plate 530, and the number of rollers 310 provided on each support rod is one. Then, the first triangle formed by the connecting plate 530 and the two first support rods 301 supports the bearing section 401 through three rollers 310, and the second triangle formed by the connecting plate 530 and the two second support rods 302 supports the return section 402 through three rollers 310.

[0065] In one embodiment, the conveyor system further includes a cable clamp 5, which includes a through portion 501 and two connecting portions 502. The connecting portions 502 are connected to the outside of the through portion 501, and the two connecting portions 502 are arranged at an included angle. A cable passes through the through portion 501, and each connecting portion 502 is connected to a strut. By passing a cable through the through portion 501 of the cable clamp 5 and connecting each connecting portion 502 to a strut, a cable and two struts are simultaneously connected to the same cable clamp 5, achieving a stable connection between the cable and the struts. This ensures the reliability of the connection between the strut assembly 3 and the cable assembly 2, and guarantees the stability of the entire system. Furthermore, the included angle between the two connecting portions 502 ensures that the included angle between the two struts connected to the same cable remains unchanged, further guaranteeing the stability of the triangular system. It should be noted that the extending direction of the connecting portion 502 is in the same direction as the axis of the strut.

[0066] like Figures 11 to 12 The diagram shows a structural schematic of cable clamp 5 (hereinafter referred to as the first cable clamp). The first cable clamp is used to connect the upper stabilizing cable 201 to the two first support rods 301, or to connect the lower stabilizing cable 202 to the two second support rods 302. The included angle between the two connecting parts 502 of the first cable clamp is the included angle θ1 between the two first support rods 301 or the included angle θ4 between the two second support rods 302.

[0067] Specifically, the cable clamp 5 includes a first cable clamp portion 510 and a second cable clamp portion 520. The first cable clamp portion 510 and the second cable clamp portion 520 are assembled to form the cable clamp 5. The first cable clamp portion 510 and the second cable clamp portion 520 each have an arc-shaped segment arranged opposite to each other. After the first cable clamp portion 510 and the second cable clamp portion 520 are spliced, the two arc-shaped segments together form a circular through portion 501. The first cable clamp portion 510 and the second cable clamp portion 520 are each provided with a corresponding fourth connecting hole 504. After the first cable clamp portion 510 and the second cable clamp portion 520 are spliced, the relative fixation of the first cable clamp portion 510 and the second cable clamp portion 520 is achieved by inserting the second connector 505 into the fourth connecting hole 504. During the installation of cable clamp 5, the first cable clamp 510 is first hung on the cable from one side, and then the second cable clamp 520 is installed from the other side of the cable. The first cable clamp 510 and the second cable clamp 520 clamp the cable together. Then, the second connector 505 is passed through the fourth connecting hole 504 on the second cable clamp 520 and the first cable clamp 510 in sequence and fixed to achieve a fixed connection between the first cable clamp 510 and the second cable clamp 520. The first cable clamp 510 and the second cable clamp 520 are assembled to form cable clamp 5, and the cable clamp 5 is connected to the cable.

[0068] Preferably, each connecting part 502 is provided with a fourth connecting hole 504, and there are multiple fourth connecting holes 504. The arrangement direction of the multiple fourth connecting holes 504 on the same connecting part 502 is parallel to the axis of the through part 501.

[0069] Preferably, the second connector 505 is a bolt, with the shank of the bolt passing through the fourth connecting hole 504. The head of the bolt abuts against the side of the second cable clamp 520 away from the first cable clamp 510. The nut is slipped onto the bolt from the side of the first cable clamp 510 away from the second cable clamp 520 and tightened, thereby fixing the first cable clamp 510 and the second cable clamp 520. The bolt connection has high strength, high reliability and low cost.

[0070] like Figures 13 to 14 The diagram shows another structural schematic of cable clamp 5 (hereinafter referred to as the second cable clamp). The second cable clamp is used to connect a load-bearing cable 203 with a first support rod 301 and a second support rod 302. The basic structure of the second cable clamp is similar to... Figures 11 to 12 The first cable clamp shown is the same, but the difference is that the angle between the two connecting parts 502 of the second cable clamp is larger. This angle is the angle between the first support rod 301 and the second support rod 302, that is, the sum of θ2 and θ5, or the sum of θ3 and θ6.

[0071] Specifically, the included angle between the two connecting parts 502 of the cable clamp 5 can be customized according to the included angle between two adjacent support rods, which is suitable for conveyor belts with different pipe diameters.

[0072] Specifically, the first clamping part 510 of the second cable clamp is located on the side of one load-bearing cable 203 away from the other load-bearing cable 203, and the second clamping part 520 is located on the side of one load-bearing cable 203 close to the other load-bearing cable 203. Correspondingly, the connecting plate 530 is connected to the second clamping parts 520 of the two oppositely arranged second cable clamps. After the cable clamps 5 are installed, a stable triangle can be formed between the connecting plate 530 and the support rod. The structure is stable and easy to assemble.

[0073] Preferably, the connecting plate 530 and the second cable clamp 520 are integrally formed, resulting in high structural strength, good stability, and ease of processing. It is understood that, as an alternative implementation, the connecting plate 530 can also be fixed to the second cable clamp 520 by welding or other methods.

[0074] Preferably, the width of the connecting plate 530 is equal to the width of the cable clamp 5, which facilitates processing and installation. Here, the width refers to the dimension of the cable clamp 5 along the cable axis.

[0075] In one embodiment, the conveyor system further includes: anchor clamps 6, such as... Figures 15 to 17 As shown, the anchor clamp 6 is U-shaped and includes two opposing side plates 601 and a base plate 602 connecting the two side plates 601. The base plate 602 has a first connecting hole 603 for the support rod to pass through. The side plates 601 have a second connecting hole 604, and the connecting part 502 has a third connecting hole 503. The second connecting hole 604 and the third connecting hole 503 are connected by a first connecting piece 605 to connect the anchor clamp 6 and the cable clamp 5. The connection between the side plates 601 and the connecting part 502 via the first connecting piece 605 achieves a fixed connection between the anchor clamp 6 and the cable clamp 5. The support rod passes through the first connecting hole 603 on the base plate 602 to connect the anchor clamp 6 and the support rod. Thus, through the cooperation of the anchor clamp 6 and the cable clamp 5, a stable connection between the support rod and the cable is achieved, resulting in good connection stability, convenient operation, and low cost.

[0076] It should be noted that after the support rod passes through the first connecting hole 603, it is then fixed from the inside of the anchor clamp 6 by the fixing member 606 to prevent the support rod from coming out of the first connecting hole 603. Specifically, the end of the support rod has external threads, and the fixing member 606 is a nut. After the end of the support rod passes through the first connecting hole 603, the nut is screwed onto the support rod from the inside of the anchor clamp 6. The outer diameter of the nut is larger than the diameter of the first connecting hole 603. Both ends of the support rod have external threads. By screwing a nut onto each end of the support rod, the support rod is limited. The inside of the anchor clamp 6 refers to the space enclosed by the two side plates 601 and the bottom plate 602. The third connecting hole 503 and the fourth connecting hole 504 on the connecting part 502 are spaced apart and do not interfere with each other. Specifically, the third connecting hole 503 is located on the side of the fourth connecting hole 504 away from the through part 501, ensuring that when the anchor clamp 6 and the cable clamp 5 are engaged, the anchor clamp 6 will not interfere with the second connecting member 505.

[0077] Specifically, the base plate 602 is located at one end of the side plate 601, and the two side plates 601 are integrally formed with the base plate 602.

[0078] Preferably, the first connector 605 is a bolt, which has high strength, low price and is easy to operate.

[0079] In one embodiment, the conveyor belt system further includes: a walkway support 7, the axis of which is perpendicular to the extension direction of the cable; the walkway support 7 is fixedly connected to the cable clamp 5 on the lower stabilizing cable 202; and a walkway 701 extending along the extension direction of the cable is provided on the walkway support 7. By fixing the walkway support 7 to the cable clamp 5 on the lower stabilizing cable 202, the walkway support 7 is connected to the lower stabilizing cable 202. The lower stabilizing cable 202 provides force to the walkway support 7, ensuring the stability of the walkway support 7, and thus ensuring the stability of the walkway 701 provided on the walkway support 7. It should be noted that the walkway 701 is provided on both sides of the conveyor belt along the width direction to facilitate workers walking and inspecting on the walkway 701. Here, the width direction refers to... Figure 8 The "width direction" indicated by the middle arrow is... Figure 5 The "width direction" indicated by the middle arrow is in the same direction.

[0080] Preferably, the walkway support component 7 is a steel round tube, which has good stability, strong support force, and is easy to install.

[0081] Specifically, each set of strut assemblies 3 is connected to a walkway support 7 at its lower end. Cable clamps 5, connected to the lower stabilizing cable 202, are welded to the walkway support 7. The cable clamps 5 clamp the lower stabilizing cable 202, thus ensuring the walkway support 7 is stably connected to the lower stabilizing cable 202. Furthermore, both ends of the lower stabilizing cable 202 are fixed to the support portion 1, and the lower stabilizing cable 202 is fixedly connected to the load-bearing cable 203 via the second strut 302. Therefore, the walkway support 7 remains stable. Preferably, the walkway support 7 has a groove, and a portion of the cable clamp 5 is embedded in and welded to the groove, further improving the stability of the connection between the walkway support 7 and the cable clamp 5.

[0082] It should be noted that the plane of walkway 701 is lower than the upper end of support column 101. There is a height difference between walkway 701 and support column 101 at the connection point. Therefore, ladders 702 are installed on both sides of support column 101 along the extension direction of the cable to ensure the continuity of the walkway and provide convenient conditions for inspection. Among them, ladders 702 are steel ladders, which have high strength and good stability.

[0083] In one embodiment, outer railings 901 are also provided at both ends of the walkway support 7 along the width direction. The outer railings 901 are perpendicular to the plane of the walkway support 7 to protect the walkway 701 and ensure the safety of the staff. A first support beam 102 extending along the width direction is provided at the top of the support column 101. The outer railings 901 are also provided at both ends of the first support beam 102 along the width direction, which also serve as a safety protection function.

[0084] In one embodiment, the walkway support 7 is further provided with a cable tray 703 and a fire water pipe 704. The cable tray 703 is used to support cables and provide power for the operation of the conveyor belt system, while the fire water pipe 704 is used to ensure fire safety.

[0085] In one embodiment, the conveyor system further includes a support base 810, which is fixedly connected to the support portion 1, and a load-bearing cable 203 is connected to the support base 810. By fixing the support base 810 to the support portion 1 and connecting the load-bearing cable 203 through the support base 810, the support base 810 supports the load-bearing cable 203, thus achieving the connection between the load-bearing cable 203 and the support portion 1. The support base 810 has good stability and high connection reliability, ensuring stable support of the load-bearing cable 203 by the support portion 1 and improving the stability of the system.

[0086] Specifically, the support part 1 has two support columns 101, which are spaced apart along the width direction. A first support beam 102 is connected between the two support columns 101. The first support beam 102 is located at the top of the support column 101. The support seat 810 is fixedly connected to the first support beam 102 to ensure the continuity of the load-bearing cable 203 when it passes through the support part 1.

[0087] In one embodiment, the support base 810 includes a saddle body 801 and a top cover 802. The saddle body 801 is fixedly connected to the first support beam 102. The top cover 802 is disposed at the upper end of the saddle body 801 and is detachably connected to the saddle body 801. The upper end of the saddle body 801 is provided with a groove, which is suitable for accommodating the load-bearing cable 203. The top cover 802 covers the opening end of the groove to prevent the load-bearing cable 203 from coming out of the groove. The upper cover 802 and the saddle 801 are connected by a third connector 803, preferably a bolt, to achieve a detachable connection between the upper cover 802 and the saddle 801. The axial filling of the load-bearing cable 203 in the groove is filled with filler 805 to ensure a tight fit between the load-bearing cable 203 and the groove, thereby ensuring the relative fixation between the load-bearing cable 203 and the support seat 810. The filler 805 is preferably rubber, which has good elasticity and is beneficial to protect the load-bearing cable 203 from wear. Preferably, the lower end of the groove is arc-shaped, and the diameter of the circle corresponding to the arc is equal to the outer diameter of the load-bearing cable 203, so that the load-bearing cable 203 is just fitted into the groove.

[0088] Preferably, the saddle body 801 is provided with stiffening ribs 804 to enhance the strength of the saddle body 801. Specifically, the dimensions of the support base 810 are designed according to the diameter of the cables.

[0089] In one embodiment, the conveyor system further includes an anchor 820, which is fixedly connected to the support 1 and corresponds to the lower stabilizing cable 202 to connect the lower stabilizing cable 202 to the support 1. By connecting the lower stabilizing cable 202 with the anchor 820 on the support 1, the lower stabilizing cable 202 is fixed on the support 1. The support 1 provides tension to the lower stabilizing cable 202, and the force on the lower stabilizing cable 202 is transmitted to the support 1 through the anchor 820, maintaining the fixed position and stress stability of the lower stabilizing cable 202, thereby ensuring the structural stability of the flexible system composed of the cable assembly 2 and the strut assembly 3.

[0090] Specifically, a second support beam 103 is connected between the two support columns 101. The second support beam 103 is located below the first support beam 102 and corresponds to the height of the lower stabilizing cable 202. An anchor 820 is connected to the second support beam 103, and the lower stabilizing cable 202 is connected to the second support beam 103 through the anchor 820.

[0091] Specifically, the number of support parts 1 is N, and the lower stabilizing cable 202 includes (N-1) segments, each of which is connected to a second support beam 103 at both ends by anchors 820. Wherein, N is greater than or equal to 2.

[0092] In one embodiment, the conveyor system further includes a photovoltaic module, comprising a photovoltaic panel, which surrounds the outside of the strut assembly 3. The photovoltaic panel surrounds the outside of the strut assembly 3, forming a closed structure to prevent materials on the conveyor belt from being blown into the surrounding environment, thus meeting environmental protection requirements. Furthermore, the photovoltaic panel can be used to convert solar energy into electrical energy. This electrical energy is connected to the circuitry of the conveyor system via the photovoltaic module's circuitry, providing power for the operation of the conveyor system and saving on additional enclosure panels. It is understood that when the conveyor system does not require enclosure, the photovoltaic module may not be necessary.

[0093] Compared with traditional conveyor belt bridges, the conveyor belt system of this embodiment has the following advantages:

[0094] 1. The conveyor system of this embodiment uses steel columns + flexible cables + struts to replace the traditional conveyor bridge. The cables have higher load-bearing capacity, better stability, simpler structural system, 50% fewer structural components, reduced load on the support part, and the overall steel consumption can be further optimized. It is lighter, has stronger crossing ability, and the span can reach about 150m. It can adapt to different complex environments such as mountains and rivers, and follow the slope. It solves the problem of insufficient crossing ability of traditional steel structure bridges.

[0095] 2. In this embodiment, the conveyor system of the pipe conveyor bears the vertical load of the structure through two load-bearing cables 203, and the horizontal load is transferred to the foundation through gravity anchor blocks 110. The force transmission path is reasonable, the force is more reasonable, materials are saved, and the cost is reduced.

[0096] 3. The cable assembly 2, strut assembly 3, and connecting plate 530 form a triangular flexible structure system, which simplifies the force distribution. Utilizing the stability of the triangle, the structure is subjected to more reasonable force, improving system stability. Furthermore, replacing the PSK plate 10 with a strut reduces steel consumption and weight. The number of idler rollers 310 is reduced from the traditional 12 to 6. With fewer idler rollers 310, the friction between the conveyor belt and the idler rollers 310 is reduced, saving energy. The reduction in the number of components makes better use of space, saves materials, and lowers costs.

[0097] 4. The connection nodes between components such as cables and struts, as well as the connection between cables and support part 1, are all bolted together on the construction site, which improves the degree of assembly, reduces construction procedures, facilitates operation, and shortens the construction period.

[0098] 5. By setting up photovoltaic modules around the strut assembly 3, the conveyor belt system can simultaneously transport materials and generate photovoltaic power. The photovoltaic panels can not only generate photovoltaic power, but also have a sealing effect, increasing revenue, saving energy and protecting the environment. In addition, the photovoltaic modules have been tested in wind tunnels and have good wind resistance. There is no need to consider the safety of the modules themselves during the structural calculation process, and no additional sealing protection measures are required during transportation and hoisting. This helps to speed up construction and save costs.

[0099] 6. The cable structure eliminates the need for regular repainting of steel structures to prevent corrosion, making it more convenient and reducing future maintenance costs.

[0100] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
