Description

Technical Field

[0001] This application belongs to the technical field of conveying equipment, and specifically relates to a suspension belt conveyor. Background Technology

[0002] Belt conveyors are mechanical devices that can continuously transport materials. They are widely used in industries such as mining, power plants, and chemicals. They can be used for transporting bulk materials (such as coal and ore) or packaged goods in horizontal or inclined directions.

[0003] Currently, there are two common types of belt conveyors: one is a belt conveyor that uses steel structure legs for rigid support, and the other is a belt conveyor that uses steel cables for suspension. Suspended belt conveyors can adapt to uneven ground, so they can be used in a wider range of scenarios.

[0004] However, suspended belt conveyors are further divided into two types. One type has the conveyor frame suspended by steel cables from a suspension device, with the cables exerting an upward tension on the frame. Idler rollers are mounted on the frame. Because the frame is made of multiple sets of transversely and longitudinally extending steel sections, this type of belt conveyor has a high manufacturing cost and is not suitable for modular production. The other type has idler rollers directly suspended from the suspension device's cables. Although this eliminates the frame design, reducing the manufacturing cost and facilitating modular production, the height of the idler rollers depends on the sag of the connection point between the idler rollers and the cables. This causes multiple idler rollers connected to the cables to rise and fall with the cables, resulting in multiple idler rollers not being at the same height or the height difference between adjacent idler rollers not being consistent, further affecting the operational stability of the belt conveyor. Utility Model Content

[0005] This application provides a cable belt conveyor to solve at least one of the above-mentioned technical problems.

[0006] The technical solution adopted in this application is as follows:

[0007] A cable-stayed belt conveyor, comprising:

[0008] A suspension assembly, the suspension assembly including steel cables and a tower for supporting the steel cables;

[0009] A conveyor belt support assembly, wherein multiple sets of the conveyor belt support assembly are arranged at intervals, and each set of the conveyor belt support assembly includes a hanging support frame, a support structure provided on the hanging support frame, and a sling provided on the hanging support frame, wherein the end of the sling away from the hanging support frame is fixedly connected to the steel cable;

[0010] An adjustment structure is provided, in which the sling is connected to the suspension support frame, and the adjustment structure is capable of adjusting the distance between the sling and the suspension support frame.

[0011] By adopting the above technical solution, when assembling the large-span steel cable belt conveyor of this application, the tower is installed first, and then the steel cable is installed so that the steel cable is connected to the tower, and then the tower supports the steel cable. Then the conveyor belt support assembly is installed so that the end of the sling away from the hanging support frame is connected to the steel cable.

[0012] Because the support structure is connected to the hanging support frame, compared to the existing technology where the support structure is directly suspended from the steel cable, the hanging support frame can support the support structure, thereby increasing the stability of the support structure and ensuring the stable operation of the cable-stayed conveyor.

[0013] Furthermore, since the suspended support frame is connected to the steel cable via slings, the length of the slings can be adjusted to ensure that multiple suspended support frames are at the same height or that the height difference between two adjacent suspended support frames remains consistent. This allows multiple sets of support structures to be at the same height or that the height difference between two adjacent support structures remains consistent, thereby further ensuring the stable operation of the cable belt conveyor.

[0014] Furthermore, since the adjustment structure can adjust the distance between the sling and the suspension support frame, after the suspension support frame is connected to the steel cable via the sling, the height of the suspension support frame relative to the ground can be adjusted by adjusting the adjustment structure. This allows multiple conveyor belt support components to be adjusted to the same height or with equal height differences. Thus, the adjustment structure can be used to adjust the suspension support frame to overcome errors generated during installation. On the one hand, this reduces the installation difficulty of the suspension belt conveyor to a certain extent, thereby improving the assembly efficiency of the suspension belt conveyor. On the other hand, it facilitates the adjustment of the height of the suspension support frame.

[0015] Optionally, the end of the hanging support frame is provided with a connector, and the adjustment structure includes a pin passing through the connector, an adjustment rod passing through the pin, and an adjustment nut threadedly connected to the adjustment rod. The adjustment nut is located at the bottom of the pin, and the sling is connected to the top end of the adjustment rod.

[0016] By adopting the above technical solution, when adjusting the height of the hanging support frame, the adjusting nut is turned, which causes the adjusting nut and the adjusting rod to rotate relative to each other. At the same time, the adjusting nut moves along the axial direction of the adjusting rod, so that the pin shaft drives the hanging support frame to move along the axial direction of the adjusting rod under the action of the adjusting nut, thereby realizing the adjustment of the height of the hanging support frame.

[0017] In summary, adjusting the height of the hanging support frame only requires turning the adjusting nut, thus reducing the difficulty of adjusting the height of the hanging support frame.

[0018] Optionally, the connector extends along the plumb line and is perpendicular to the plane formed by the hanging support frame, and the pin is perpendicular to the connector.

[0019] By adopting the above technical solution, since the connecting part extends along the plumb line and is perpendicular to the plane formed by the hanging support frame, and the pin is set perpendicular to the connecting part, the hanging support frame can rotate around the pin in the conveying direction of the conveyor belt. This allows the hanging support frame to adjust itself according to the material on the conveyor belt, making the hanging support frame suitable for various working conditions, increasing the flexibility of the hanging support frame and further ensuring the stable operation of the suspension belt conveyor.

[0020] Optionally, the connector is provided with reinforcing plates located on both sides of the pin, and the projection of the reinforcing plates toward the connector at least covers the connection position between the connector and the top beam or the connector being connected to the top beam.

[0021] By adopting the above technical solution, since the reinforcing plate is located on the connector and the projection of the reinforcing plate toward the connector at least covers the connection position between the connector and the top beam, on the one hand, the reinforcing plate can increase the structural strength of the connector to ensure its service life; on the other hand, the reinforcing plate can also increase the connection strength between the connector and the top beam to a certain extent, avoiding the situation where the connector can deform in a direction away from the top beam, which would cause tearing at the connection position between the connector and the top beam, thereby ensuring the connection stability between the connector and the top beam.

[0022] Since the reinforcing plate is located on the connector and connected to the top beam, it increases the structural strength of the connector to ensure its structural strength, and also increases the connection stability between the connector and the top beam.

[0023] Optionally, the reinforcing plate is provided with a support plate, the pin passes through the support plate, and the adjusting rod is located between the connector and the support plate.

[0024] By adopting the above technical solution, since the pin is also inserted through the support plate, the support plate can support and limit the pin, thereby increasing the stability of the pin; and since the adjusting rod is located between the connector and the support plate, the pin can be subjected to force balance as much as possible, thereby further increasing the stability of the pin, and further increasing the stability of the hanging support frame.

[0025] Optionally, a U-shaped plate is provided at the top end of the adjusting rod, and the sling is connected to the U-shaped plate by fasteners.

[0026] By adopting the above technical solution, since one end of the sling is located inside the U-shaped plate and connected to the U-shaped plate by fasteners, the connection stability between the sling and the adjustment structure is increased on the one hand, and the installation difficulty of the sling is reduced on the other hand, thereby improving the assembly efficiency of the sling and thus improving the assembly efficiency of the belt conveyor.

[0027] Optionally, the end of the hanging support frame is provided with a connector, the adjustment structure includes a hydraulic cylinder, the piston rod of the hydraulic cylinder is connected to the connector, the cylinder body of the hydraulic cylinder has a rod chamber and a rodless chamber, and the rod chambers of multiple hydraulic cylinder bodies are interconnected.

[0028] By adopting the above technical solution, for horizontal conveying operations of cable belt conveyors, if the height of one support structure differs from that of other support structures, the support structure at the higher position will experience greater pressure compared to the others during material transport. Since the rod chambers of multiple hydraulic cylinders are interconnected, the support structure at the higher position will move downwards under the pressure difference. This causes the piston rod of the hydraulic cylinder corresponding to the higher support structure to move downwards, displacing some hydraulic oil and allowing it to enter the rod chambers of other hydraulic cylinders. This increases the amount of hydraulic oil in the rod chambers of the other cylinders, causing their piston rods to drive their corresponding suspension supports and support structures upwards. This ensures that all support structures are at the same height and experience the same stress, thus extending the service life of the cable belt conveyor and reducing its failure rate.

[0029] In the case of inclined conveying of materials by a cable belt conveyor, if the height of a certain support structure is higher than its required height, the height difference between this support structure and its adjacent support structures will differ from the height difference between other adjacent support structures. This will cause the support structure at the higher position to experience greater pressure compared to other support structures during material transport. Since the rod chambers of multiple hydraulic cylinders are interconnected, the support structure at the higher position will move downwards under the pressure difference. This causes the piston rod of the hydraulic cylinder corresponding to the higher support structure to move downwards, displacing some hydraulic oil from that cylinder and allowing it to enter the rod chambers of other hydraulic cylinders. This increases the amount of hydraulic oil in the rod chambers of the other hydraulic cylinders, causing their piston rods to drive their corresponding suspension supports and support structures upwards. Ultimately, this ensures that all support structures are at the same height and experience the same stress, thus extending the service life of the cable belt conveyor and reducing its failure rate.

[0030] In addition, if the material distribution on the conveyor belt is uneven during material transport, each conveyor belt support component adjusts its height via a hydraulic cylinder according to the pressure it receives, in order to distribute and reduce the pressure it receives, thereby extending the service life of the suspension belt conveyor.

[0031] This application, by setting up hydraulic cylinders and making the rod chambers of multiple hydraulic cylinders interconnected, enables the conveyor belt support assembly to dynamically adjust according to the distribution of materials on the conveyor belt, thereby making the force on the conveyor belt support assembly more uniform and extending the service life of the suspension belt conveyor.

[0032] Optionally, it also includes a connection component, which includes a flexible connector extending longitudinally, the flexible connector being connected to the tower and sequentially connected to a plurality of the hanging support frames.

[0033] By adopting the above technical solution, since the flexible connectors connect multiple hanging support frames in sequence, the design of longitudinal beams is omitted compared with the existing frame-setting scheme, thereby greatly reducing the amount of steel used and thus greatly reducing the production and manufacturing cost of the suspension belt conveyor. At the same time, it also reduces the installation difficulty of the suspension belt conveyor, thereby increasing the safety of the suspension belt conveyor during installation.

[0034] Furthermore, because the flexible connector is attached to the tower, it can stably connect multiple suspended support frames together, thereby increasing the stability of the suspended support frames and further ensuring the stable operation of the cable belt conveyor. Moreover, due to the flexibility of the flexible connector, compared with the existing frame-based solution, the self-adjustment capability of the suspended support frames is greatly improved, allowing each suspended support frame to be appropriately adjusted according to the operating conditions, further ensuring the stable operation of the cable belt conveyor and extending its service life.

[0035] Optionally, the hanging support frame includes a top beam, a first connecting beam disposed at the bottom of the top beam, and a second connecting beam disposed at the bottom of the top beam. The first connecting beam and the second connecting beam are spaced apart. One end of the support structure is connected to the first connecting beam, and the other end of the support structure is connected to the second connecting beam.

[0036] By adopting the above technical solution, since the hanging support frame includes a top beam, a first connecting beam and a second connecting beam, the structural design of the hanging support frame is simplified while ensuring the structural strength of the hanging support frame, thereby reducing the amount of steel used in the hanging support frame and further reducing the production and manufacturing cost of the suspension belt conveyor.

[0037] Optionally, the top beam includes a first side beam and a second side beam arranged at an angle to the first side beam, the first connecting beam being connected to the first side beam, and the second connecting beam being connected to the second side beam;

[0038] Alternatively, the top beam may be a curved beam structure that protrudes toward the side opposite to the supporting structure.

[0039] By adopting the above technical solution, since the first side beam and the second side beam are set at an angle, and the first connecting beam is connected to the first side beam and the second connecting beam is connected to the second side beam, the conveyor belt support assembly is located below the first side beam and the second side beam. This ensures that the conveying space formed between the conveyor belt support assembly and the top beam is large enough, avoiding the situation where the conveying capacity of the conveyor belt is affected due to the small space between the top beam and the conveyor belt support assembly, thereby ensuring the conveying efficiency of the belt conveyor.

[0040] Because the top beam is a curved beam structure that protrudes away from the direction where the conveyor belt support assembly is located, the conveying space formed between the top beam and the conveyor belt support assembly is large enough. This avoids the situation where the conveyor belt conveying capacity is affected due to the small space between the top beam and the conveyor belt support assembly, thereby ensuring the conveying efficiency of the belt conveyor.

[0041] Optionally, the hanging support frame further includes a first reinforcing beam located outside the first connecting beam and a second reinforcing beam located outside the second connecting beam. The two ends of the first reinforcing beam are respectively connected to the first connecting beam and the top beam, and the two ends of the second reinforcing beam are respectively connected to the second connecting beam and the top beam.

[0042] By adopting the above technical solution, since the first reinforcing beam is located outside the first connecting beam and the second reinforcing beam is located outside the second connecting beam, the first and second reinforcing beams can avoid the conveyor belt support assembly and the material being conveyed by the conveyor belt, so as to ensure the conveying capacity of the conveyor belt and thus ensure the conveying efficiency of the belt conveyor.

[0043] Since the two ends of the first reinforcing beam are connected to the top beam and the first connecting beam respectively, the top beam, the first reinforcing beam and the first connecting beam can form a triangle together to increase the connection stability of the first connecting beam and the top beam, thereby ensuring the support effect of the hanging support frame on the conveyor belt support assembly, and thus ensuring the stability of the conveyor belt support assembly.

[0044] Since the two ends of the second reinforcing beam are connected to the top beam and the second connecting beam respectively, the top beam, the second reinforcing beam and the second connecting beam can form a triangle together to increase the connection stability between the second connecting beam and the top beam, thereby ensuring the support effect of the hanging support frame on the conveyor belt support assembly, and thus ensuring the stability of the conveyor belt support assembly.

[0045] Optionally, the top beam, the first connecting beam, and the second connecting beam are all equipped with U-shaped rope clips, and the flexible connector is threaded through the U-shaped rope clips.

[0046] By adopting the above technical solution, since the flexible connector is threaded through the U-shaped rope clamp, the flexible connector can be fixedly connected to the hanging support frame using the U-shaped rope clamp, thereby increasing the connection stability between the flexible connector and the hanging support frame, and also increasing the stability between two adjacent hanging support frames; since the top beam, the first connecting beam and the second connecting beam are all equipped with U-shaped rope clamps, multiple flexible connectors can be used to connect the hanging support frame, thereby increasing the number of connection points of the hanging support frame through the flexible connectors, and further increasing the stability of the hanging support frame.

[0047] Optionally, the cable-stayed conveyor may further include a flexible protective cover that extends longitudinally and is sequentially connected to a plurality of the top beams.

[0048] By adopting the above technical solution, since the flexible protective cover extends longitudinally and connects multiple top beams in sequence, the flexible protective cover is located on top of the support structure. This allows the flexible protective cover to protect the conveyor belt that supports the support structure, preventing rainwater from falling directly onto the conveyor belt and wetting the materials. At the same time, the flexible protective cover can also play a role in wind protection for the materials being conveyed by the conveyor belt, reducing the possibility of materials being scattered by the wind, thereby ensuring the conveying efficiency of the suspension belt conveyor.

[0049] Optionally, the top beam is a curved beam structure, at least one end of the curved beam structure is provided with a fixing member, the fixing member has a receiving groove, and the top of the flexible protective cover is provided with a corrugated elastic rod extending longitudinally, the side of the corrugated elastic rod extending into the receiving groove.

[0050] Alternatively, the top of the flexible protective cover is provided with multiple fixing strips at intervals, and the fixing strips are fixedly connected to the top beam.

[0051] By adopting the above technical solution, the corrugated elastic rod is fixed by extending its side into the receiving groove. Since the corrugated elastic rod is located at the top of the flexible protective cover, it not only allows for the fixation of the flexible protective cover, reducing the difficulty and improving the fixing efficiency, but also provides upward support, increasing the stability of the flexible protective cover and preventing it from moving up and down due to uneven material distribution on the conveyor belt. This, in turn, increases the service life of the flexible protective cover to some extent.

[0052] Since the fixing strip is located at the top of the flexible protective cover and is fixedly connected to the top beam, it not only achieves the fixation of the flexible protective cover and increases its stability, but also reduces the difficulty of fixing the flexible protective cover.

[0053] Optionally, the suspension assembly further includes a swing frame for supporting the steel cable and a stabilizing cable connected to the tower. The bottom end of the swing frame is hinged to the ground, and the stabilizing cable is connected to the top end of the tower and can fix the top end of the swing frame.

[0054] By adopting the above technical solution, since one end of the swing frame is hinged to the ground and the stabilizing cable can fix the top end of the swing frame, the bending or tearing at the connection point with the ground caused by the rigid connection between the swing frame and the ground is avoided. At the same time, using the stabilizing cable to fix the swing frame increases the stability of the swing frame and reduces the difficulty of fixing it. In addition, since the tower is large in volume and heavy, it is necessary to build a concrete connection seat at the installation location of the tower. However, by adding swing frames with smaller volume and weight, the number of towers can be reduced, which further reduces the production and manufacturing cost of the suspension belt conveyor. Furthermore, since the swing frame has lower requirements for the foundation and concrete connection seat, the installation cost of the suspension belt conveyor can also be reduced.

[0055] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0056] 1. The suspension belt conveyor of this application includes a suspension assembly, a conveyor belt support assembly, and an adjustment structure. The suspension assembly includes a steel cable and a tower for supporting the steel cable. Multiple sets of conveyor belt support assemblies are arranged at intervals. Each set of conveyor belt support assemblies includes a hanging support frame, a support structure provided on the hanging support frame, and a sling provided on the hanging support frame. The end of the sling away from the hanging support frame is fixedly connected to the steel cable. The sling is connected to the hanging support frame through adjustment, and the adjustment structure can adjust the distance between the sling and the hanging support frame. Compared with the prior art scheme of directly suspending the support structure on the steel cable, this allows the hanging support frame to support the support structure, thereby increasing the stability of the support structure and ensuring the stable operation of the suspension belt conveyor. This also ensures that multiple hanging support frames are at the same height or that the height difference between two adjacent hanging support frames is consistent, thus ensuring that multiple sets of support structures are at the same height or that the height difference between two adjacent sets of support structures is consistent, further guaranteeing the stable operation of the suspension belt conveyor.

[0057] 2. The suspended support frame in this application includes a top beam, a first connecting beam located at the bottom of the top beam, and a second connecting beam located at the bottom of the top beam. The first connecting beam and the second connecting beam are spaced apart. One end of the support structure is connected to the first connecting beam, and the other end of the support structure is connected to the second connecting beam. This simplifies the structural design of the suspended support frame while ensuring its structural strength, thereby reducing the amount of steel used in the suspended support frame and further reducing the production cost of the suspension belt conveyor.

[0058] 3. The top beam in this application includes a first side beam and a second side beam arranged at an angle to the first side beam. A first connecting beam is connected to the first side beam, and a second connecting beam is connected to the second side beam. This allows the conveyor belt support assembly to be located below the first and second side beams, ensuring that the conveying space formed between the conveyor belt support assembly and the top beam is large enough. This avoids the situation where the conveyor belt conveying capacity is affected due to the small space between the top beam and the conveyor belt support assembly, thereby ensuring the conveying efficiency of the belt conveyor.

[0074] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0075] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0079] Reference Figures 1 to 12 A suspension belt conveyor is disclosed, comprising a suspension assembly, a conveyor belt support assembly, and an adjustment structure 4. The suspension assembly includes a steel cable 11 and a tower 12 for supporting the steel cable 11. Multiple sets of conveyor belt support assemblies are arranged at intervals. Each set of conveyor belt support assemblies includes a hanging support frame 21, a support structure 22 provided on the hanging support frame 21 for supporting the conveyor belt, and a sling 23 provided on the hanging support frame 21. The end of the sling 23 away from the hanging support frame 21 is fixedly connected to the steel cable 11. The sling 23 is connected to the hanging support frame through the adjustment structure 4, and the adjustment structure 4 can adjust the distance between the sling and the hanging support frame 21.

[0080] It is understood that at least two towers 12 are provided at intervals, and steel cables 11 are fixedly connected to the top of multiple towers 12 so that the towers 12 can support the steel cables 11; the suspension belt conveyor also includes a conveyor belt, which passes through multiple support structures 22 in sequence and is located above the support structures 22 so that multiple conveyor belt support components support the conveyor belt.

[0081] When assembling the large-span steel cable 11 belt conveyor of this application, the tower 12 is installed first, and then the steel cable 11 is installed so that the steel cable 11 is connected to the tower 12, and then the tower 12 supports the steel cable 11. Then the conveyor belt support assembly is installed so that the end of the sling 23 away from the hanging support frame 21 is connected to the steel cable 11.

[0082] Since the support structure 22 is connected to the hanging support frame 21, compared with the prior art where the support structure 22 is directly suspended from the steel cable 11, the hanging support frame 21 can support the support structure 22, thereby increasing the stability of the support structure 22 and ensuring the stable operation of the cable belt conveyor.

[0083] Furthermore, since the suspended support frame 21 is connected to the steel cable 11 via the sling 23, the length of the sling 23 can be adjusted so that multiple suspended support frames 21 are at the same height or the height difference between two adjacent suspended support frames 21 remains consistent. This allows multiple sets of support structures 22 to be at the same height or the height difference between two adjacent sets of support structures 22 to remain consistent, thereby further ensuring the stable operation of the cable belt conveyor.

[0084] Furthermore, since the sling 23 is connected to the suspension support frame 21 through the adjustment structure 4, and after the suspension support frame 21 is connected to the steel cable 11 through the sling 23, the height of the suspension support frame 21 relative to the ground can be adjusted by adjusting the adjustment structure 4. This allows multiple conveyor belt support components to be adjusted to the same height or with equal height differences. Thus, the adjustment of the suspension support frame 21 by the adjustment structure 4 can overcome the errors generated during the installation process. On the one hand, this reduces the installation difficulty of the suspension belt conveyor to a certain extent, thereby improving the assembly efficiency of the suspension belt conveyor. On the other hand, it facilitates the adjustment of the height of the suspension support frame 21.

[0085] This application does not specifically limit the structure of the sling 23. Preferably, the sling 23 is a structure made of steel wire rope to reduce the production cost of the suspension belt conveyor and ensure the connection stability between the conveyor belt support assembly and the steel cable 11. In other embodiments, the sling 23 may also be a circular chain or other structure capable of suspending the conveyor belt support assembly from the steel cable 11.

[0086] This application does not impose specific limitations on the adjustment structure 4, which can be any of the following embodiments:

[0087] Implementation Method 1, in this implementation method, refer to Figures 2 to 5The end of the hanging support frame 21 is provided with a connector 231. The adjustment structure 4 includes a pin 41 passing through the connector 231, an adjustment rod 42 passing through the pin 41, and an adjustment nut 43 threadedly connected to the adjustment rod 42. The adjustment nut 43 is located at the bottom of the pin 41, and the sling 23 is connected to the top end of the adjustment rod 42.

[0088] It is understandable that the adjusting rod 42 is provided with external threads so that the adjusting nut 43 can be threadedly connected to the adjusting rod 42.

[0089] When adjusting the height of the hanging support frame 21, the adjusting nut 43 is turned, which causes the adjusting nut 43 to rotate relative to the adjusting rod 42. At the same time, the adjusting nut 43 moves along the axial direction of the adjusting rod 42, thereby causing the pin 41 to drive the hanging support frame 21 to move along the axial direction of the adjusting rod 42 under the action of the adjusting nut 43, so as to achieve the adjustment of the height of the hanging support frame 21.

[0090] In summary, when adjusting the height of the hanging support frame 21, only the adjusting nut 43 needs to be turned, thus reducing the difficulty of adjusting the height of the hanging support frame 21.

[0091] This application does not specifically limit the structure of connector 231; preferably, refer to... Figures 2 to 6 The connector 231 is a plate-like structure welded to the end of the suspension support frame 21 to increase the connection stability between the connector 231 and the top beam 211 and reduce the manufacturing difficulty of the suspension support frame 21. In other embodiments, the connector 231 may also be a U-shaped rod or other structure located at the end of the suspension support frame 21.

[0092] Preferably, at least one side of the adjusting nut 43 is provided with a stop protrusion located on the side of the pin 41, so that when the adjusting nut 43 abuts against the pin 41, the stop protrusion cooperates with the side stop of the pin 41 to limit the adjustment nut 43, so as to prevent the adjusting nut 43 from rotating relative to the adjusting rod 42 under non-human action, thereby increasing the stability of the hanging support frame 21.

[0093] It should be noted that the adjusting nut 43 is provided with a stop protrusion located on the side of the pin 41. Therefore, when the adjusting nut 43 is rotated, an upward thrust needs to be applied to the hanging support frame 21 first, so that the hanging support frame 21 drives the pin 41 to move upward, thereby separating the stop protrusion from the pin 41, so that the adjusting nut 43 can rotate.

[0094] Furthermore, refer to Figures 2 to 5The connector 231 extends along the plumb line and is perpendicular to the plane formed by the hanging support frame 21. The pin 41 is perpendicular to the connector 231, which allows the hanging support frame 21 to rotate around the pin 41 in the conveying direction of the conveyor belt. This allows the hanging support frame 21 to adjust itself according to the material on the conveyor belt, making it suitable for various working conditions, increasing the flexibility of the hanging support frame 21 and further ensuring the stable operation of the suspension belt conveyor.

[0095] It should be noted that a pin 41 retaining ring is provided on the pin 41 to limit the pin 41 and prevent the pin 41 from disengaging from the connecting plate.

[0096] Furthermore, refer to Figures 2 to 5 The connector 231 is provided with reinforcing plates 232 located on both sides of the pin 41. The projection of the reinforcing plates 232 toward the connector 231 at least covers the connection position between the connector 231 and the top beam 211.

[0097] It is understandable that there are two reinforcing plates 232, each of which is fixedly connected to the connector 231 by welding, and the reinforcing plate 232 is located on the side of the connector 231 away from the top beam 211.

[0098] Since the reinforcing plate 232 is provided on the connector 231, and the projection of the reinforcing plate 232 toward the connector 231 at least covers the connection position between the connector 231 and the top beam 211, on the one hand, the reinforcing plate 232 can increase the structural strength of the connector 231 to ensure the service life of the connector 231. On the other hand, the reinforcing plate 232 can also increase the connection strength between the connector 231 and the top beam 211 to a certain extent, avoiding the situation where the connection position between the connector 231 and the top beam 211 is torn due to the deformation of the connector 231 in the direction away from the top beam 211, thereby ensuring the connection stability between the connector 231 and the top beam 211.

[0099] Of course, in order to increase the connection stability between the connecting frame and the top beam 211, a reinforcing plate 232 can be provided on the side of the connecting piece 231 facing the top beam 211. One side of the reinforcing plate 232 is fixedly connected to the connecting piece 231 by welding, and the other side of the reinforcing plate 232 is fixedly connected to the top beam 211 by welding. This increases the structural strength of the connecting plate to ensure the structural strength of the connecting piece 231, and also increases the connection stability between the connecting piece 231 and the top beam 211.

[0100] Furthermore, refer to Figures 2 to 5The reinforcing plate 232 is provided with a support plate 233, and the pin 41 passes through the support plate 233. The adjusting rod 42 is located between the connector 231 and the support plate 233.

[0101] It is understandable that the support plate 233 is located between the two reinforcing plates 232, and both ends of the support plate 233 are fixedly connected to the two reinforcing plates 232 by welding.

[0102] Since the pin 41 is also inserted through the support plate 233, the support plate 233 can support and limit the pin 41, thereby increasing the stability of the pin 41. Furthermore, since the adjusting rod 42 is located between the connector 231 and the support plate 233, it can balance the force on the pin 41 as much as possible, thereby further increasing the stability of the pin 41 and further increasing the stability of the hanging support frame 21.

[0103] Preferably, the support plate 233 and the connector 231 are arranged parallel to each other at intervals, so that the pin 41 can also be perpendicularly inserted into the support plate 233.

[0104] This application does not specify the connection method between the sling 23 and the adjusting rod 42. Preferably, refer to... Figures 2 to 5 A U-shaped plate 421 is provided at the top end of the adjusting rod 42. The sling 23 is connected to the U-shaped plate 421 by fasteners. This increases the connection stability between the sling 23 and the adjusting structure 4, and reduces the installation difficulty of the sling 23, thereby improving the assembly efficiency of the sling 23 and thus improving the assembly efficiency of the belt conveyor.

[0105] Preferably, the sling 23 is located inside the U-shaped plate 421 so that the bottom end of the sling 23 is subjected to balanced force.

[0106] In other implementation examples, a fixing ring may be provided at the end of the adjusting rod 42 away from the pin 41, and the steel cable 11 is fixedly connected to the fixing ring by interlocking rings.

[0107] This application does not specifically limit the structure of the fastener. Preferably, the fastener is a pin with an R-shaped retaining pin, so as to reduce the difficulty of connecting the sling 23 and the U-shaped plate 421 while ensuring the stability of the connection. In other embodiments, the fastener can also be a bolt pair or other structures that can connect the sling 23 and the U-shaped plate 421.

[0108] This application does not specifically limit the connection method between the adjusting rod 42 and the U-shaped plate 421. Preferably, the adjusting rod 42 is fixedly connected to the U-shaped plate 421 by welding to increase the connection stability between the adjusting rod 42 and the U-shaped plate 421. In other embodiments, the adjusting rod 42 is a bolt, which passes through the U-shaped plate 421 so that the bolt head of the adjusting rod 42 and the U-shaped plate 421 stop and engage in the vertically downward direction.

[0109] Implementation Method Two: In this implementation method, refer to... Figure 6 The end of the hanging support frame 21 is provided with a connector 231. The adjustment structure 4 includes a hydraulic cylinder 44. The piston rod of the hydraulic cylinder 44 is connected to the connector 231. The cylinder body of the hydraulic cylinder 44 has a rod chamber and a rodless chamber. The rod chambers of multiple hydraulic cylinders 44 are interconnected.

[0110] It is understandable that the rod chambers of multiple hydraulic cylinders 44 located on the same side of multiple hanging support frames 21 are interconnected, and the rod chambers of multiple hydraulic cylinders 44 located on the other side of multiple hanging support frames 21 are interconnected.

[0111] In the case of horizontal conveying of a cable belt conveyor, if the height of one support structure 22 is different from that of other support structures 22, the support structure 22 at the higher position will experience greater pressure compared to the others during material transport. Since the rod chambers of multiple hydraulic cylinders 44 are interconnected, the support structure 22 at the higher position will move downwards under the pressure difference. This causes the piston rod of the corresponding hydraulic cylinder 44 to move downwards, displacing some hydraulic oil and allowing it to enter the rod chambers of other hydraulic cylinders 44. This increases the amount of hydraulic oil in the rod chambers of the other hydraulic cylinders 44, causing their piston rods to drive their corresponding suspension support frame 21 and support structures 22 upwards. This ensures that all support structures 22 are at the same height and experience the same force, thus extending the service life of the cable belt conveyor and reducing its failure rate.

[0112] In the case of inclined conveying of materials by a cable belt conveyor, if the height of a certain support structure 22 is higher than its required height, the height difference between this support structure 22 and its adjacent support structures 22 will be different from the height difference between other adjacent sets of support structures 22. This will cause the support structure 22 at the higher position to experience greater pressure compared to other support structures 22 during material conveying. Since the rod chambers of multiple hydraulic cylinders 44 are interconnected, the support structure 22 at the higher position will move downwards under the pressure difference. This causes the piston rod of the hydraulic cylinder 44 corresponding to the higher-positioned support structure 22 to move downwards, so that some of the hydraulic oil in this hydraulic cylinder 44 is squeezed out and enters the rod chamber of other hydraulic cylinders 44. Ultimately, this increases the amount of hydraulic oil in the rod chamber of other hydraulic cylinders 44, causing the piston rod of the other hydraulic cylinders 44 to drive their corresponding hanging support frame 21 and support structure 22 to move upwards. This ensures that all support structures 22 are at the same height and that all support structures 22 are subjected to the same force, thereby ensuring the service life of the cable belt conveyor and reducing the failure rate of the cable belt conveyor.

[0113] In addition, if the material distribution on the conveyor belt is uneven during material transport, each conveyor belt support component adjusts its height through hydraulic cylinder 44 according to the pressure it receives, so as to distribute and reduce the pressure it receives and extend the service life of the suspension belt conveyor.

[0114] This application sets up hydraulic cylinders 44 and makes the rod chambers of multiple hydraulic cylinders 44 interconnected, so that the conveyor belt support assembly can be dynamically adjusted according to the distribution of materials on the conveyor belt, so that the force on the conveyor belt support assembly is more uniform, thereby extending the service life of the suspension belt conveyor.

[0115] It should be noted that the rod chamber refers to the oil chamber located at the bottom of the piston inside the cylinder body when the hydraulic cylinder 44 is arranged vertically and the piston rod is located at the bottom of the cylinder body, while the oil chamber located at the top of the piston is the rodless chamber; the rod chambers of multiple hydraulic cylinders 44 are interconnected through pipelines. The hydraulic cylinder 44 in this application does not need to be equipped with an oil tank and a hydraulic oil pump, and it is regulated by the hydraulic oil stored in the pipelines and rod chambers.

[0116] In addition, since the multiple hanging support frames 21 in this application can be dynamically adjusted according to the distribution of materials on the conveyor belt, the reliability of the suspension belt conveyor is improved, thereby greatly reducing the failure rate of the suspension belt conveyor. As a result, the suspension belt conveyor in this application can eliminate the design of the pedestrian walkway suspended by the steel cable 11, thereby further reducing the production and manufacturing cost of the suspension belt conveyor and improving the efficiency of its installation.

[0117] This application does not specifically limit the relationship between the rodless chambers of the multiple hydraulic cylinders 44, which can also be interconnected, and can also be directly connected to the air after the internal hydraulic oil is emptied.

[0118] This application does not specify the connection method between the piston rod and the connecting member 231. Preferably, the piston rod is fixedly connected to the connecting member 231 by a bolt pair, so that the piston rod and the connecting member 231 are relatively fixed while allowing relative rotation between them. In other embodiments, the piston rod can also be connected to the connecting member 231 by other fixing structures.

[0119] In other implementation examples, the solutions of implementation example 1 and implementation example 2 can be combined so that the conveyor belt support component can be adjusted automatically as well as manually; or, the adjustment structure 4 can be a tensioning screw buckle.

[0120] In a preferred embodiment, the cable-stayed conveyor further includes a connecting assembly, which includes a flexible connector 31 extending longitudinally, the flexible connector 31 being connected to the tower 12 and sequentially connected to a plurality of hanging support frames 21.

[0121] Understandably, the end of the flexible connector 31 is fixedly connected to the tower 12 to increase the stability of the flexible connector 31.

[0122] It should be noted that the longitudinal direction mentioned in this application refers to the direction in which one of two adjacent towers 12 faces the other tower 12; that is, the longitudinal direction refers to the conveying direction of the conveyor belt.

[0123] Meanwhile, the flexible connector 31 connects multiple hanging support frames 21 in sequence. Compared with the existing frame-setting scheme, the design of the longitudinal beam is omitted, which greatly reduces the amount of steel used and thus greatly reduces the production and manufacturing cost of the suspension belt conveyor. It also reduces the installation difficulty of the suspension belt conveyor, thereby increasing the safety of the suspension belt conveyor during installation.

[0124] Furthermore, since the flexible connector 31 is connected to the tower 12, it can stably connect multiple hanging support frames 21 together, thereby increasing the stability of the hanging support frames 21 and further ensuring the stable operation of the cable belt conveyor. Moreover, since the flexible connector 31 is flexible, compared with the existing frame-setting scheme, it greatly improves the self-adjustment capability of the hanging support frames 21, so that each hanging support frame 21 can be appropriately adjusted according to the operating conditions, thereby further ensuring the stable operation of the cable belt conveyor and extending its service life.

[0125] Furthermore, since the support structure 22 is located on the hanging support frame 21, and multiple hanging support frames 21 are connected together by flexible connectors 31, the conveyor belt support components can be produced as separate modules. When assembling the cable belt conveyor, the number of conveyor belt support components can be increased or decreased according to the construction site conditions, so that the cable belt conveyor is no longer constrained by the frame, thereby increasing the flexibility of the cable belt conveyor.

[0126] This application does not specifically limit the structure of the flexible connector 31. Preferably, the flexible connector 31 is a steel wire rope to ensure the connection stability of two adjacent suspension support frames 21, while reducing the production and manufacturing cost of the suspension belt conveyor. In other embodiments, the flexible connector 31 can also be a circular chain or other flexible component capable of connecting multiple suspension support frames 21 together.

[0127] This application does not specifically limit the structure of the hanging support frame 21; preferably, refer to... Figure 2 and Figure 3 The hanging support frame 21 includes a top beam 211, a first connecting beam 212 located at the bottom of the top beam 211, and a second connecting beam 213 located at the bottom of the top beam 211. The first connecting beam 212 and the second connecting beam 213 are spaced apart. One end of the support structure 22 is connected to the first connecting beam 212, and the other end of the support structure 22 is connected to the second connecting beam 213.

[0128] Since the suspension support frame 21 includes a top beam 211, a first connecting beam 212 and a second connecting beam 213, the structural design of the suspension support frame 21 is simplified while ensuring the structural strength of the suspension support frame 21, thereby reducing the amount of steel used in the suspension support frame 21 and further reducing the production and manufacturing cost of the suspension belt conveyor.

[0129] This application does not specifically limit the structure of the top beam 211, the first connecting beam 212, and the second connecting beam 213. Preferably, the top beam 211 is an I-beam to ensure its structural strength, and the first connecting beam 212 and the second connecting beam 213 are both angle steels to ensure their structural strength and reduce the manufacturing cost of the belt conveyor. In other embodiments, the top beam 211 can also be a C-shaped steel or other steel profile, and the first connecting beam 212 and the second connecting beam 213 can also be C-shaped steel, H-shaped steel, or other steel profiles.

[0130] This application does not specifically limit the structure of the top beam 211, which can adopt any of the following embodiments:

[0131] Example 1, in this example, refers to Figure 2 and Figure 3 The top beam 211 includes a first side beam 216 and a second side beam 217 arranged at an angle to the first side beam 216. A first connecting beam 212 is connected to the first side beam 216, and a second connecting beam 213 is connected to the second side beam 217. This allows the conveyor belt support assembly to be located below the first side beam 216 and the second side beam 217, ensuring that the conveying space formed between the conveyor belt support assembly and the top beam 211 is large enough. This avoids the situation where the conveyor belt conveying capacity is affected due to the small space between the top beam 211 and the conveyor belt support assembly, thereby ensuring the conveying efficiency of the belt conveyor.

[0132] It is understandable that the top beam 211 is a structure formed by splicing the first side beam 216 and the second side beam 217, and the first side beam 216 and the second side beam 217 are fixedly connected. The first side beam 216 and the second side beam 217 are inclined downwards in a direction that is far away from each other.

[0133] This application does not specify a particular method for fixing the first side beam 216 and the second side beam 217. Preferably, the first side beam 216 and the second side beam 217 are fixedly connected by welding to increase the stability of the connection. In other embodiments, plate-like structures are provided at the ends of the first side beam 216 and the second side beam 217 that are close to each other. The two plate-like structures are fixedly connected by bolts to achieve a fixed connection between the first side beam 216 and the second side beam 217.

[0134] Example 2, in this example, refer to Figure 7 The top beam 211 is a curved beam structure that protrudes toward the side opposite to the support structure 22, which makes the conveying space between the top beam 211 and the conveyor belt support assembly large enough. This avoids the situation where the conveying capacity of the conveyor belt is affected due to the small space between the top beam 211 and the conveyor belt support assembly, thereby ensuring the conveying efficiency of the belt conveyor.

[0135] Understandably, the top beam 211 is an integral structure to ensure its structural strength and reduce the number of components required for assembly, thereby reducing the production and manufacturing cost of the large-span steel cable 11 belt conveyor.

[0136] Preferably, the top beam 211 is arched to ensure a large conveying space between the top beam 211 and the conveyor belt support assembly.

[0137] In a preferred embodiment, refer to Figure 2 and Figure 3The hanging support frame 21 also includes a first reinforcing beam 214 located outside the first connecting beam 212 and a second reinforcing beam 215 located outside the second connecting beam 213. The two ends of the first reinforcing beam 214 are respectively connected to the first connecting beam 212 and the top beam 211, and the two ends of the second reinforcing beam 215 are respectively connected to the second connecting beam 213 and the top beam 211.

[0138] It should be noted that the outer side of the first connecting beam 212 refers to the side of the first connecting beam 212 that is away from the second connecting beam 213, and the outer side of the second connecting beam 213 refers to the side of the second connecting beam 213 that is away from the first connecting beam 212.

[0139] Since the first reinforcing beam 214 is located outside the first connecting beam 212 and the second reinforcing beam 215 is located outside the second connecting beam 213, the first reinforcing beam 214 and the second reinforcing beam 215 can avoid the conveyor belt support assembly and the material being conveyed by the conveyor belt, so as to ensure the conveying capacity of the conveyor belt and thus ensure the conveying efficiency of the belt conveyor.

[0140] Since the two ends of the first reinforcing beam 214 are connected to the top beam 211 and the first connecting beam 212 respectively, the top beam 211, the first reinforcing beam 214 and the first connecting beam 212 can form a triangle together, thereby increasing the connection stability between the first connecting beam 212 and the top beam 211, thus ensuring the support effect of the hanging support frame 21 on the conveyor belt support assembly, and thus ensuring the stability of the conveyor belt support assembly.

[0141] Since the two ends of the second reinforcing beam 215 are connected to the top beam 211 and the second connecting beam 213 respectively, the top beam 211, the second reinforcing beam 215 and the second connecting beam 213 can form a triangle together, thereby increasing the connection stability between the second connecting beam 213 and the top beam 211, thus ensuring the support effect of the hanging support frame 21 on the conveyor belt support assembly, and thus ensuring the stability of the conveyor belt support assembly.

[0142] This application does not specifically limit the structure of the first reinforcing beam 214 and the second reinforcing beam 215. Preferably, both the first reinforcing beam 214 and the second reinforcing beam 215 are angle steel, so as to reduce the production cost of the hanging support frame 21 while ensuring the structural strength of the first reinforcing beam 214 and the second reinforcing beam 215. In other embodiments, the first reinforcing beam 214 and the second reinforcing beam 215 can also be other types of steel such as H-beams and C-beams.

[0143] This application does not specifically limit the connection method between the first reinforcing beam 214 and the first connecting beam 212, or the connection method between the second reinforcing beam 215 and the second connecting beam 213. Preferably, the first reinforcing beam 214 is fixedly connected to the first connecting beam 212 by bolt pairs, and the second reinforcing beam 215 is also fixedly connected to the second connecting beam 213 by bolt pairs. This ensures the stability of the connection between the first reinforcing beam 214 and the first connecting beam 212 while facilitating the assembly of the first reinforcing beam 214, and also ensures the stability of the connection between the second reinforcing beam 215 and the second connecting beam 213 while facilitating the assembly of the second reinforcing beam 215. In other embodiments, the first reinforcing beam 214 can also be fixedly connected to the first connecting beam 212 by welding, and the second reinforcing beam 215 can also be fixedly connected to the second connecting beam 213 by welding.

[0144] This application does not specify the connection method between the first reinforcing beam 214, the second reinforcing beam 215, and the top beam 211. Preferably, refer to... Figure 2 and Figure 3 At the bottom of the top beam 211, mounting plates 218 are welded to the first reinforcing beam 214 and the second reinforcing beam 215. Both the first reinforcing beam 214 and the second reinforcing beam 215 are fixedly connected to their corresponding mounting plates 218 by bolt pairs. In other embodiments, the first reinforcing beam 214 and the second reinforcing beam 215 are also fixedly connected to the top beam 211 by welding.

[0145] This application does not specifically limit the connection method between the first connecting beam 212, the second connecting beam 213, and the top beam 211. Preferably, refer to... Figure 2 and Figure 3 The bottom of the top beam 211 is welded with a fixing plate 219 corresponding to the first connecting beam 212 and the second connecting beam 213. The first connecting beam 212 and the second connecting beam 213 are fixedly connected to their corresponding fixing plates 219 by bolt pairs. This ensures the stability of the connection between the first connecting beam 212 and the second connecting beam 213 and the top beam 211, while reducing the production difficulty of the hanging support frame 21. It also allows the first connecting beam 212 and the second connecting beam 213 to have slight shaking with the top beam 211, so as to avoid the rigid connection between the first connecting beam 212 and the second connecting beam 213 and the top beam 211, which would cause tearing at the connection position. This increases the connection stability between the first connecting beam 212 and the second connecting beam 213 and the top beam 211.

[0146] This application does not specify the number of slings 23 in each conveyor belt support assembly. Preferably, each conveyor belt support assembly has two slings 23, which are respectively connected to both ends of the top beam 211 along its length. Two steel cables 11 are provided, with one sling 23 connected to one steel cable 11 and the other sling 23 connected to the other steel cable 11. This increases the stability of the suspension support frame 21 while reducing the manufacturing cost of the suspension belt conveyor. In other embodiments, each conveyor belt support assembly may have only one sling 23, and also one steel cable 11; or each conveyor belt support assembly may have multiple slings 23, with multiple steel cables 11 corresponding to multiple slings 23.

[0147] In a preferred embodiment, refer to Figure 2 and Figure 3 The top beam 211, the first connecting beam 212, and the second connecting beam 213 are all equipped with U-shaped rope clips 230. Flexible connectors 31 are threaded through the U-shaped rope clips 230, thereby using the U-shaped rope clips 230 to fix the flexible connectors 31 to the hanging support frame 21, increasing the connection stability between the flexible connectors 31 and the hanging support frame 21, and also increasing the stability between two adjacent hanging support frames 21. Since the top beam 211, the first connecting beam 212, and the second connecting beam 213 are all equipped with U-shaped rope clips 230, multiple flexible connectors 31 can be used to connect the hanging support frame 21, increasing the number of connection points of the hanging support frame 21 through the flexible connectors 31, thereby further increasing the stability of the hanging support frame 21.

[0148] It should be noted that the U-shaped rope clips 230 on the multiple hanging support frames 21 are set one-to-one so that the flexible connector 31 is connected to each hanging support frame 21 in a straight line.

[0149] In a preferred embodiment, refer to Figures 7 to 11 The suspension belt conveyor also includes a flexible protective cover 5, which extends longitudinally and is connected to multiple top beams 211 in sequence. The flexible protective cover 5 is located on top of the support structure 22, so that the flexible protective cover 5 can protect the conveyor belt supported by the support structure 22 to prevent rainwater from falling directly onto the conveyor belt and wetting the material. At the same time, the flexible protective cover 5 can also play a role in wind protection for the material being conveyed by the conveyor belt to a certain extent, so as to reduce the material being scattered by the wind, thereby ensuring the conveying efficiency of the suspension belt conveyor.

[0150] This application does not specifically limit the structure of the flexible protective cover 5. Preferably, the flexible protective cover 5 is a rainproof cloth to ensure the protective effect of the flexible protective cover 5 on the materials on the conveyor belt, while also reducing the production and manufacturing cost of the suspension belt conveyor. In other embodiments, the flexible protective cover 5 may also be a rainproof plastic film.

[0151] In this embodiment, the structure of the top beam 211 and the fixing method of the flexible protective cover 5 are not specifically limited, and any one of the following embodiments can be adopted:

[0152] Example 1, in this example, refers to Figure 8 and Figure 9 The top beam 211 is a curved beam structure, and at least one end of the curved beam structure is provided with a fastener 511. Each fastener 511 has a receiving groove. The top of the flexible protective cover 5 is provided with a corrugated elastic rod 51 extending longitudinally, and the side parts of the corrugated elastic rod 51 extend into the receiving groove.

[0153] Since the side of the corrugated elastic rod 51 extends into the receiving groove, the corrugated elastic rod 51 is fixed. The corrugated elastic rod 51 is located at the top of the flexible protective cover 5. On the one hand, the corrugated elastic rod 51 can fix the flexible protective cover 5, thereby reducing the difficulty of fixing the flexible protective cover 5 and improving the fixing efficiency. On the other hand, the corrugated elastic rod 51 can also provide support in the upward direction to increase the stability of the flexible protective cover 5 and avoid the situation where the flexible protective cover 5 moves up and down under the action of airflow due to uneven distribution of materials on the conveyor belt. This, in turn, increases the service life of the flexible protective cover 5 to a certain extent.

[0154] It should be noted that when installing the corrugated elastic rod 51, the side of the flexible protective cover 5 is inserted into the receiving groove so that the corrugated elastic rod 51 can fix the side of the flexible protective cover 5 to the fixing member.

[0155] When the included angle between two adjacent segments of the corrugated elastic rod 51 is small, fixing members 511 can be provided at both ends of the curved beam structure so that the same curved beam structure can fix both sides of the corrugated elastic rod 51; when the included angle between two adjacent segments of the corrugated elastic rod 51 is large, fixing members 511 only need to be provided at one end of the curved beam structure, and the fixing members 511 on the two adjacent hanging support frames 21 are respectively located on both sides of the corrugated elastic rod 51.

[0156] Example 2, in this example, refer to Figure 10 and Figure 11The top beam 211 is also a curved beam structure. Multiple fixing strips 52 are spaced apart on the top of the flexible protective cover 5. The fixing strips 52 are fixedly connected to the top beam 211, which on the one hand realizes the fixation of the flexible protective cover 5, increases the stability of the flexible protective cover 5, and on the other hand reduces the difficulty of fixing the flexible protective cover 5.

[0157] This application does not specifically limit the shape of the fixing strip 52. Preferably, the shape of the fixing strip 52 is adapted to the shape of the top beam 211 to further increase the fixing stability of the fixing strip 52 on the flexible protective cover 5. In other embodiments, the fixing strip 52 can also be a straight strip structure, and the fixing strip 52 is elastic so that the fixing strip 52 can fit against the flexible protective cover 5 and fix the flexible protective cover 5.

[0158] This application does not specify a particular number of fixing strips 52. Preferably, the number of fixing strips 52 is the same as the number of hanging support frames 21, and the fixing strips 52 are arranged one-to-one with the top beam 211 to increase the number of fixing points for the flexible protective cover 5, thereby further increasing the stability of the flexible protective cover 5. In other embodiments, the number of fixing strips 52 may be less than the number of hanging support frames 21. For example, a fixing strip 52 may be provided on the top of one of two adjacent hanging support frames 21 to reduce the manufacturing cost of the cable belt conveyor.

[0159] This application does not specify the method of fixing the fixing strip 52 to the top beam 211. Preferably, the fixing strip 52 is fixed to the top beam 211 by screws, so as to reduce the difficulty of fixing the fixing strip 52 and increase the connection stability between the fixing strip 52 and the top beam 211. In other embodiments, the fixing strip 52 can also be fixed to the top beam 211 by bolts.

[0160] In other embodiments, both ends of the flexible protective cover 5 in the width direction are provided with through holes corresponding to the top beam 211, and a connecting rope is provided at the top of the flexible protective cover 5. The two ends of the connecting rope pass through the corresponding through holes and are fixedly connected to the top beam 211 to fix the flexible protective cover 5; or, the top of the flexible protective cover 5 is provided with a mesh structure of other shapes such as rhombus, grid, or scale (e.g., Figure 12 As shown in the figure, this is to fix the flexible protective cover 5. In this embodiment, the top beam 211 can be a curved beam structure or the structure mentioned above composed of the first side beam 216 and the second side beam 217.

[0161] In a preferred embodiment, refer to Figure 1 and Figure 7The suspension assembly also includes a swing frame 13 for supporting the steel cable 11 and a stabilizing cable 14 connected to the tower 12. The bottom end of the swing frame 13 is hinged to the ground, and the stabilizing cable 14 is connected to the top end of the tower 12 and can fix the top end of the swing frame 13.

[0162] It is understandable that the hinge axis of the swing frame 13 is set perpendicular to the length direction of the stabilizing cable 14 so that the stabilizing cable 14 can fix one end of the top of the swing frame 13 under the action of the tower 12.

[0163] Since the bottom end of the swing frame 13 is hinged to the ground, and the stabilizing cable 14 can fix the top end of the swing frame 13, the bending or tearing at the connection point with the ground caused by the rigid connection of the swing frame 13 to the ground is avoided. At the same time, using the stabilizing cable 14 to fix the swing frame 13 increases the stability of the swing frame 13 and reduces the difficulty of fixing the swing frame 13. In addition, since the tower 12 is large in volume and heavy, a concrete connecting seat needs to be built at the installation location of the tower 12. However, by adding the swing frame 13, which is smaller in volume and weight, the number of towers 12 can be reduced. This further reduces the production cost of the suspension belt conveyor. Furthermore, since the swing frame 13 has lower requirements for the foundation and concrete connecting seat, the installation cost of the suspension belt conveyor can also be reduced.

[0164] This application does not impose specific restrictions on the hinged connection method between the swing frame 13 and the ground. Preferably, a hinge seat is pre-embedded in the ground, and the swing frame 13 is hinged to the hinge seat to achieve the hinged connection between the swing frame 13 and the ground. In other embodiments, the swing frame 13 can also be hinged to the ground by using other methods of pre-embedded hinge shafts in the ground.

[0165] This application does not impose specific limitations on the supporting structure 22; however, preferred options are as follows: Figure 2 and Figure 6 The support structure 22 includes multiple idlers arranged in two rows, with one row of idlers staggered with the other row. This allows each idler to be made larger to ensure support for the conveyor belt and also increases the installation space for the idlers, making it easier to install them.

[0166] Of course, in other embodiments, multiple idlers are arranged in a row, and the force balance of the hanging support frame 21 in the plumb direction can be achieved by setting the central axis of the multiple idlers on the plane where the hanging support frame 21 is located, so as to facilitate the stability of the hanging support frame 21.

[0167] Understandably, the support structure 22 also includes a frame, with the rollers installed on the frame. One end of the frame is fixedly connected to the first connecting beam 212, and the other end of the frame is fixedly connected to the second connecting beam 213. When multiple rollers are arranged in a row, the frame is directly fixedly connected to the first connecting beam 212 and the second connecting beam 213. When multiple rollers are divided into two rows, the frame is provided with two rollers corresponding to the two rows of rollers. The two rows of rollers are located on both sides of the first connecting beam 212 and the second connecting beam 213, respectively. Angle steel is provided on both the first connecting beam 212 and the second connecting beam 213. The two frames are located at the two ends of the two angle steels and are fixedly connected to the angle steels.

[0168] In other embodiments, the support structure 22 may also include a trolley that travels on the flexible connector 31 to support the conveyor belt.

[0169] For any parts not mentioned in this application, existing technologies may be used or referenced.

[0170] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0171] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
