Description

Technical Field

[0001] This application belongs to the technical field of belt conveyor equipment, specifically relating to a suspended idler device for a 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 is directly supported by steel structure legs, and the other is a belt conveyor that is suspended by a suspension device. 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 divided into two types. One type has the conveyor frame suspended by steel cables from a suspension device, so that the cables exert an upward tension on the frame. Idler rollers are installed on the frame. Because the frame is made of multiple sets of transverse and longitudinally extending steel sections, the manufacturing cost of this type of belt conveyor is high and it is not convenient for modular production. The other type has idler rollers directly suspended from the suspension device's cables. Although this eliminates the frame design, reduces the manufacturing cost of the belt conveyor, and achieves the effect of facilitating modular production, the stability of its idler rollers is poor, which in turn affects the stability of the belt conveyor. Utility Model Content

[0005] This application provides a suspended idler device for belt conveyors, which reduces the manufacturing cost of belt conveyors and facilitates modular production of belt conveyors while ensuring the stability of belt conveyors.

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

[0007] A suspended idler roller device for a belt conveyor, comprising:

[0008] The idler frame includes a top beam, a first connecting beam connected to the top beam, and a second connecting beam connected to the top beam. The top of the top beam is provided with a hoisting position, and the first connecting beam and the second connecting beam are both located at the bottom of the top beam and are spaced apart from each other.

[0009] An idler assembly, one end of which is connected to the first connecting beam and the other end of which is connected to the second connecting beam;

[0010] A sling, one end of which is connected to the hoisting position.

[0011] By adopting the above technical solution, when assembling a belt conveyor with the suspended idler device of this application, the bracket is assembled first, and then the end of the sling away from the hoisting position is connected to the steel cable of the suspension device so that the steel cable of the suspension device applies an upward pulling force to the suspended idler device. After all the suspended idler devices are installed, the conveyor belt is assembled so that the suspended idler devices support the conveyor belt.

[0012] Because the suspended idler device in this application includes an idler frame, one end of the idler assembly is connected to the first connecting beam of the idler frame, the other end of the idler assembly is connected to the second connecting beam of the idler frame, and the sling is connected to the hoisting position located on the top beam, compared with the prior art solution of directly suspending the idler on the steel cable, the idler frame can support the idler assembly, thereby increasing the stability of the idler assembly, ensuring the stable operation of the belt conveyor, and thus increasing the stability of the belt conveyor.

[0013] Furthermore, compared to the prior art where the frame is suspended by steel cables, the suspended roller device in this application eliminates the design of longitudinal beams, thereby reducing the amount of structural steel used in the belt conveyor and thus reducing the production cost of the belt conveyor. At the same time, the suspended roller device is a separate module, which facilitates the modular production of the belt conveyor.

[0014] In addition, since the idler roller assembly is located below the top beam, the rain cover can also be installed on the top beam, making it easier to install the rain cover.

[0015] Optionally, at least two hoisting positions are provided, each located at one end of the top beam;

[0016] Alternatively, at least one hoisting position may be provided and located in the middle of the top beam.

[0017] By adopting the above technical solution, since there are at least two hoisting positions located at both ends of the top beam, the connection points between the suspended roller device and the suspension device are increased, thereby increasing the stability of the suspended roller device and further ensuring the stable operation of the belt conveyor.

[0018] Since there is at least one hoisting position located in the middle of the top beam, the number of connection points between the suspended roller device and the suspension device is reduced, thereby improving the assembly efficiency of the belt conveyor and reducing the production cost of the belt conveyor.

[0019] 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;

[0020] Alternatively, the top beam may be a curved beam structure that protrudes in a direction away from the location of the idler roller assembly.

[0021] 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 idler roller assembly is located below the first side beam and the second side beam, so as to ensure that a conveying space can be formed between the idler roller assembly and the top beam, thereby reducing the generation of dust while ensuring the conveying space.

[0022] Because the top beam is a curved beam structure that protrudes away from the direction where the idler roller assembly is located, a conveying space can be formed between the top beam and the idler roller assembly, which reduces dust generation while ensuring the conveying space.

[0023] Optionally, the idler frame further includes a first reinforcing beam and a second reinforcing beam. The first reinforcing beam is located outside the first connecting beam, and one end of the first reinforcing beam is connected to the top beam, while the other end of the first reinforcing beam is connected to the first connecting beam. The second reinforcing beam is located outside the second connecting beam, and one end of the second reinforcing beam is connected to the top beam, while the other end of the second reinforcing beam is connected to the second connecting beam.

[0024] 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 contact with the idler assembly and the material being conveyed by the conveyor belt, thereby ensuring the conveying capacity of the conveyor belt and thus ensuring the conveying efficiency of the belt conveyor.

[0025] 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 roller frame on the roller assembly, and thus ensuring the stability of the roller assembly.

[0026] 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 roller frame on the roller assembly and thus ensuring the stability of the roller assembly.

[0027] Optionally, the sling is connected to the hoisting position via an adjustment structure, which can adjust the distance between the sling and the hoisting position.

[0028] By adopting the above technical solution, since the sling is connected to the hoisting position through the adjustment structure, and the adjustment structure can adjust the distance between the sling and the hoisting position, after the suspended idler roller device is installed on the suspension device, the height of the idler roller assembly relative to the ground can be adjusted by adjusting the adjustment structure. This allows multiple suspended idler roller devices suspended on the suspension device to be adjusted to the same height or with equal height differences. On the one hand, this reduces the difficulty of suspending the suspended idler roller device to a certain extent, thereby improving the assembly efficiency of the belt conveyor. On the other hand, it facilitates the adjustment of the suspended idler roller device.

[0029] At the same time, it can also adapt to the changes in the angle between the idler frame and the sling caused by the force during inclined conveying by adjusting the relative rotation between the adjustment structure and the idler frame.

[0030] Optionally, the adjustment structure includes a pin connected to the hoisting position, an adjustment rod passing through the pin, and an adjustment nut threaded 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.

[0031] By adopting the above technical solution, when adjusting the height of the idler frame, the adjusting nut is turned, causing 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, thereby causing the pin to drive the idler frame to move along the axial direction of the adjusting rod under the action of the adjusting nut, so as to realize the adjustment of the height of the idler frame. When adjusting the position of the idler frame, only the adjusting nut needs to be turned, thus reducing the difficulty of adjusting the position of the idler frame.

[0032] Optionally, the top beam is provided with a connecting plate that forms the hoisting position. The connecting plate extends along the direction of the plumb bob and is perpendicular to the plane formed by the roller frame. The pin passes through the connecting plate and is perpendicular to the connecting plate.

[0033] By adopting the above technical solution, since the connecting plate constitutes the hoisting position and the pin passes through the connecting plate, the connection difficulty between the pin and the hoisting position is reduced, and the connection stability between the pin and the hoisting position is increased. Furthermore, since the connecting plate extends along the plumb line and is perpendicular to the plane formed by the idler frame, and the pin is set perpendicular to the connecting plate, the idler frame can rotate around the pin in the conveying direction of the conveyor belt. This allows the idler frame to adjust itself according to the material conditions on the conveyor belt, thereby making the idler frame suitable for various working conditions and increasing the flexibility of the idler frame.

[0034] Optionally, the connecting plate is provided with reinforcing plates located on both sides of the pin shaft, and the projection of the reinforcing plates toward the connecting plate at least covers the connection position between the connecting plate and the top beam, or the reinforcing plates are connected to the top beam.

[0035] By adopting the above technical solution, since the reinforcing plate is located on the connecting plate and the projection of the reinforcing plate toward the connecting plate at least covers the connection position between the connecting plate and the top beam, on the one hand, the reinforcing plate can increase the structural strength of the connecting plate to ensure the service life of the connecting plate. On the other hand, the reinforcing plate can also increase the connection strength between the connecting plate and the top beam to a certain extent, avoiding the situation where the connecting plate can deform in a direction away from the top beam, which would cause tearing at the connection position between the connecting plate and the top beam, thereby ensuring the connection stability between the connecting plate and the top beam.

[0036] Since the reinforcing plate is located on the connecting plate and connected to the top beam, it increases the structural strength of the connecting plate to ensure its structural strength, and also increases the connection stability between the connecting plate and the top beam.

[0037] Optionally, a support plate is provided on the side of the reinforcing plate away from the connecting plate. The support plate is arranged parallel to and spaced apart from the connecting plate. The pin passes through the support plate, and the adjusting rod is located between the connecting plate and the support plate.

[0038] By adopting the above technical solution, since the pin shaft passes through the support plate at the same time and the adjusting rod is located between the connecting plate and the support plate, the pin shaft can be balanced by force, thereby increasing the stability of the pin shaft and ensuring the stability of the roller frame.

[0039] Optionally, one end of the top of the adjusting rod is provided with a U-shaped plate with an opening facing away from the adjusting rod, and one end of the sling is located inside the U-shaped plate and connected to the U-shaped plate by fasteners.

[0040] 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.

[0041] Optionally, the top beam, the first connecting beam, and the second connecting beam are all provided with U-shaped rope clips for the longitudinal steel wire rope to pass through.

[0042] By adopting the above technical solution, since the top beam, the first connecting beam and the second connecting beam are all equipped with U-shaped rope clamps for longitudinal steel wire ropes to pass through, multiple suspended roller devices suspended on the suspension device can be connected together by longitudinal steel wire ropes passing through the U-shaped rope clamps, so as to avoid the situation where multiple suspended roller devices can swing relative to each other in the longitudinal direction, thereby ensuring the stability of the belt conveyor.

[0043] Optionally, the idler assembly includes multiple idlers arranged in two rows, wherein one row of idlers is staggered with the other row of idlers, or the multiple idlers are arranged in one row.

[0044] By adopting the above technical solution, since multiple idlers are arranged in two rows and the two rows of idlers are staggered, each idler can be made larger to ensure the support effect on the conveyor belt, reduce running resistance, and at the same time, to a certain extent, increase the installation space of the idlers to facilitate the installation of the idlers.

[0045] Since multiple idlers are arranged in a row, the force balance of the idler frame in the vertical direction can be achieved by setting the central axis of the multiple idlers on the plane where the idler frame is located, so as to facilitate the stability of the idler frame.

[0046] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0047] 1. The suspended idler roller device of this application includes an idler roller frame, an idler roller assembly, and a sling. The idler roller frame includes a top beam, a first connecting beam connected to the top beam, and a second connecting beam connected to the top beam. A hoisting position is provided at the top of the top beam. The first and second connecting beams are both located at the bottom of the top beam and are spaced apart. One end of the idler roller assembly is connected to the first connecting beam, and the other end of the idler roller assembly is connected to the second connecting beam. One end of the sling is connected to the hoisting position. Therefore, compared with the prior art solution of directly suspending the idler roller on a steel cable, the idler roller... The frame supports the idler assembly, thereby increasing the stability of the idler assembly and ensuring the stable operation of the belt conveyor. Compared with the existing technology where the frame is suspended from the steel cable by wire rope, the suspended idler device in this application eliminates the longitudinal beam design, thereby reducing the amount of structural steel used in the belt conveyor and thus reducing the production cost of the belt conveyor. At the same time, the suspended idler device is a separate module, which facilitates the modular production of the belt conveyor.

[0048] 2. The lifting positions in this application are provided at least two and are located on both sides of the top beam, thereby increasing the connection points between the suspended roller device and the suspension device, so as to increase the stability of the suspended roller device and further ensure the stable operation of the belt conveyor.

[0049] 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, thereby placing the idler assembly below the first and second side beams to ensure that a conveying space can be formed between the idler assembly and the top beam. While ensuring the conveying space, the generation of dust is reduced, and the conveying efficiency of the belt conveyor is guaranteed. Attached Figure Description

[0062] Reference Figures 1 to 4 A suspended idler device for a belt conveyor is disclosed, comprising an idler frame 1, an idler assembly 2, and a sling 3. The idler frame 1 includes a top beam 11, a first connecting beam 12 connected to the top beam 11, and a second connecting beam 13 connected to the top beam 11. A hoisting position is provided at the top of the top beam 11. The first connecting beam 12 and the second connecting beam 13 are both located at the bottom of the top beam 11 and are spaced apart. One end of the idler assembly 2 is connected to the first connecting beam 12, and the other end of the idler assembly 2 is connected to the second connecting beam 13. One end of the sling 3 is connected to the hoisting position.

[0063] When assembling a belt conveyor with the suspended idler device described in this application, the suspension device is assembled first, and then the end of the sling 3 away from the hoisting position is fixedly connected to the steel cable of the suspension device so that the steel cable of the suspension device applies an upward tension to the suspended idler device. After all the suspended idler devices are installed, the conveyor belt is assembled so that the suspended idler devices support the conveyor belt.

[0064] Since the suspended idler device in this application includes an idler frame 1, one end of the idler assembly 2 is connected to the first connecting beam 12 of the idler frame 1, the other end of the idler assembly 2 is connected to the second connecting beam 13 of the idler frame 1, and the sling 3 is connected to the hoisting position provided on the top beam 11, compared with the prior art scheme of directly suspending the idler on the steel cable, the idler frame 1 can support the idler assembly 2, thereby increasing the stability of the idler assembly 2, so as to ensure the stable operation of the belt conveyor, and thus increasing the stability of the belt conveyor.

[0065] Furthermore, compared to the prior art where the frame is suspended by steel cables, the suspended roller device in this application eliminates the design of multiple longitudinal beams, thereby reducing the amount of structural steel used in the belt conveyor and thus reducing the production cost of the belt conveyor. At the same time, the suspended roller device becomes a separate module, which facilitates the modular production of the belt conveyor.

[0066] In addition, since the idler roller assembly 2 is located below the top beam 11, the rain cover can also be installed on the top beam 11 to facilitate the installation of the rain cover.

[0067] This application does not specifically limit the structure of the sling 3. Preferably, the sling 3 is a structure made of steel wire rope to reduce the production cost of the belt conveyor and ensure the connection stability between the suspended roller device and the suspension device. In other embodiments, the sling 3 may also be a circular chain or other structure capable of suspending the roller frame 1 to the suspension device.

[0068] This application does not specifically limit the structure of the top beam 11, the first connecting beam 12, and the second connecting beam 13. Preferably, refer to Figure 1 and Figure 2 The top beam 11 is made of I-beam to ensure its structural strength. The first connecting beam 12 and the second connecting beam 13 are both angle steel to ensure their structural strength and reduce the manufacturing cost of the belt conveyor. In other embodiments, the top beam 11 can also be C-shaped steel or other types of steel, and the first connecting beam 12 and the second connecting beam 13 can also be C-shaped steel, H-shaped steel, or other types of steel.

[0069] This application does not specify the number or location of the hoisting positions, and any of the following implementation methods can be adopted:

[0070] Implementation Method 1, in this implementation method, refer to Figure 1 and Figure 2 At least two hoisting positions are provided, located at both ends of the top beam 11, thereby increasing the connection points between the suspended roller device and the suspension device, increasing the stability of the suspended roller device, and further ensuring the stable operation of the belt conveyor.

[0071] Preferably, there are two hoisting positions, one of which is located at one end of the top beam 11 and the other is located at the other end of the top beam 11.

[0072] In the second embodiment, at least one hoisting position is provided and located in the middle of the top beam 11, thereby reducing the number of connection points between the hanging roller device and the suspension device, thus improving the assembly efficiency of the belt conveyor and reducing the production cost of the belt conveyor.

[0073] Preferably, there is one hoisting position, and the hoisting position is located at the middle position along the length of the top beam 11.

[0074] Of course, in other embodiments, there may be three hoisting positions, with two hoisting positions located at the two ends of the top beam 11 and the other hoisting position located in the middle of the length of the top beam 11, to increase the connection stability between the suspended roller device and the suspension device; or there may be more than three hoisting positions.

[0075] This application does not impose specific limitations on the structure of the top beam 11, which can adopt any of the following embodiments:

[0076] Implementation Method 1, in this implementation method, refer to Figure 1 and Figure 2 The top beam 11 includes a first side beam 111 and a second side beam 112 arranged at an angle to the first side beam 111. A first connecting beam 12 is connected to the first side beam 111, and a second connecting beam 13 is connected to the second side beam 112. This allows the idler roller assembly 2 to be located below the first side beam 111 and the second side beam 112, ensuring that a conveying space can be formed between the idler roller assembly 2 and the top beam 11. While ensuring the conveying space, dust generation is reduced, and the conveying efficiency of the belt conveyor is guaranteed.

[0077] It is understood that one end of the first side beam 111 is fixedly connected to one end of the second side beam 112, and the first side beam 111 and the second side beam 112 are inclined downwards in a direction that is far away from each other.

[0078] In the second embodiment, the top beam 11 is a curved beam structure that protrudes in the direction away from the idler assembly 2, thereby forming a conveying space between the top beam 11 and the idler assembly 2. While ensuring the conveying space, the generation of dust is reduced, and the conveying efficiency of the belt conveyor is guaranteed.

[0079] Preferably, the top beam 11 is arched to ensure a large conveying space between the top beam 11 and the idler roller assembly 2.

[0080] In a preferred embodiment, refer to Figure 1 and Figure 2 The roller frame 1 also includes a first reinforcing beam 14 and a second reinforcing beam 15. The first reinforcing beam 14 is located outside the first connecting beam 12, and one end of the first reinforcing beam 14 is connected to the top beam 11, while the other end of the first reinforcing beam 14 is connected to the first connecting beam 12. The second reinforcing beam 15 is located outside the second connecting beam 13, and one end of the second reinforcing beam 15 is connected to the top beam 11, while the other end of the second reinforcing beam 15 is connected to the second connecting beam 13.

[0081] It should be noted that the outer side of the first connecting beam 12 refers to the side of the first connecting beam 12 that is away from the second connecting beam 13, and the outer side of the second connecting beam 13 refers to the side of the second connecting beam 13 that is away from the first connecting beam 12.

[0082] Since the first reinforcing beam 14 is located outside the first connecting beam 12 and the second reinforcing beam 15 is located outside the second connecting beam 13, the first reinforcing beam 14 and the second reinforcing beam 15 can avoid contact with the idler assembly 2 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.

[0083] Since the two ends of the first reinforcing beam 14 are connected to the top beam 11 and the first connecting beam 12 respectively, the top beam 11, the first reinforcing beam 14 and the first connecting beam 12 form a triangle, thereby increasing the connection stability between the first connecting beam 12 and the top beam 11, thus ensuring the support effect of the roller frame 1 on the roller assembly 2, and thus ensuring the stability of the roller assembly 2.

[0084] Since the two ends of the second reinforcing beam 15 are connected to the top beam 11 and the second connecting beam 13 respectively, a triangle is formed between the top beam 11, the second reinforcing beam 15 and the second connecting beam 13, thereby increasing the connection stability between the second connecting beam 13 and the top beam 11, thus ensuring the support effect of the roller frame 1 on the roller assembly 2, and thus ensuring the stability of the roller assembly 2.

[0085] This application does not specifically limit the structure of the first reinforcing beam 14 and the second reinforcing beam 15. Preferably, both the first reinforcing beam 14 and the second reinforcing beam 15 are angle steel, so as to reduce the production cost of the roller frame 1 while ensuring the structural strength of the first reinforcing beam 14 and the second reinforcing beam 15. In other embodiments, the first reinforcing beam 14 and the second reinforcing beam 15 can also be other types of steel such as H-beams, C-beams, or steel pipes.

[0086] This application does not specifically limit the connection method between the first reinforcing beam 14 and the first connecting beam 12, or the connection method between the second reinforcing beam 15 and the second connecting beam 13. Preferably, the first reinforcing beam 14 is fixedly connected to the first connecting beam 12 by bolt pairs, and the second reinforcing beam 15 is also fixedly connected to the second connecting beam 13 by bolt pairs. This ensures the stability of the connection between the first reinforcing beam 14 and the first connecting beam 12 while facilitating the assembly of the first reinforcing beam 14, and also ensures the stability of the connection between the second reinforcing beam 15 and the second connecting beam 13 while facilitating the assembly of the second reinforcing beam 15. In other embodiments, the first reinforcing beam 14 can also be fixedly connected to the first connecting beam 12 by welding, and the second reinforcing beam 15 can also be fixedly connected to the second connecting beam 13 by welding.

[0087] This application does not specify the connection method between the first reinforcing beam 14 and the second reinforcing beam 15 and the top beam 11. Preferably, the bottom of the top beam 11 is welded with a mounting plate 114 corresponding to the first reinforcing beam 14 and the second reinforcing beam 15, and both the first reinforcing beam 14 and the second reinforcing beam 15 are fixedly connected to their corresponding mounting plates 114 by bolt pairs. In other embodiments, the first reinforcing beam 14 and the second reinforcing beam 15 are also fixedly connected to the top beam 11 by welding.

[0088] This application does not specifically limit the connection method between the first connecting beam 12 and the second connecting beam 13 and the top beam 11. Preferably, the bottom of the top beam 11 is welded with a fixing plate 113 corresponding to the first connecting beam 12 and the second connecting beam 13. The first connecting beam 12 and the second connecting beam 13 are fixedly connected to their corresponding fixing plates 113 by bolt pairs. This ensures the connection stability between the first connecting beam 12 and the second connecting beam 13 and the top beam 11, while reducing the production difficulty of the roller frame 1. It also allows the first connecting beam 12 and the second connecting beam 13 to generate slight wobbling with the top beam 11, so as to avoid the rigid connection between the first connecting beam 12 and the second connecting beam 13 and the top beam 11, which would cause tearing at the connection position. This increases the connection stability between the first connecting beam 12 and the second connecting beam 13 and the top beam 11.

[0089] In a preferred embodiment, refer to Figures 1 to 4The sling 3 is connected to the hoisting position via the adjusting structure 4. The adjusting structure 4 can adjust the distance between the sling 3 and the hoisting position. After the suspended roller device is installed on the suspension device, the height of the roller assembly 2 relative to the ground can be adjusted by adjusting the adjusting structure 4. This allows multiple suspended roller devices suspended on the suspension device to be adjusted to the same height or with equal height differences. This reduces the difficulty of suspending the suspended roller device to a certain extent, thereby improving the assembly efficiency of the belt conveyor. It also facilitates the adjustment of the suspended roller device. At the same time, the relative rotation between the adjusting structure and the roller frame can be used to adapt to the angle change between the roller frame and the sling caused by the force during inclined conveying.

[0090] This application does not specifically limit the adjustment structure 4; preferably, refer to... Figures 1 to 4 The adjustment structure 4 includes a pin 41 connected to the hoisting position, an adjustment rod 42 passing through the pin 41, and an adjustment nut 43 threaded to the adjustment rod 42. The adjustment nut 43 is located at the bottom of the pin 41, and the sling 3 is connected to the top end of the adjustment rod 42.

[0091] 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.

[0092] When adjusting the height of the idler frame 1, the adjusting nut 43 is turned, causing 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 idler frame 1 to move along the axial direction of the adjusting rod 42 under the action of the adjusting nut 43, so as to realize the adjustment of the height of the idler frame 1. This makes it possible to adjust the position of the idler frame 1 simply by turning the adjusting nut 43, thus reducing the difficulty of adjusting the position of the idler frame 1.

[0093] 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 adjusting 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 roller frame 1.

[0094] 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 roller frame 1 first, so that the roller frame 1 drives the pin 41 to move upward, thereby separating the stop protrusion from the pin 41, so that the adjusting nut 43 can rotate.

[0095] Furthermore, refer to Figures 1 to 4 The top beam 11 is provided with a connecting plate 115 that forms a hoisting position. The connecting plate 115 extends along the plumb line and is perpendicular to the plane formed by the roller frame 1. The pin 41 passes through the connecting plate 115 and is perpendicular to the connecting plate 115.

[0096] It is understandable that the connecting plate 115 is fixedly connected to the top beam 11 by welding. After one end of the pin 41 passes through the connecting plate 115, a pin retainer needs to be installed on the pin 41 to limit the pin 41 and prevent the pin 41 from separating from the connecting plate 115.

[0097] Since the connecting plate 115 forms a lifting position and the pin 41 passes through the connecting plate 115, the connection difficulty between the pin 41 and the lifting position is reduced, and the connection stability between the pin 41 and the lifting position is increased. Furthermore, since the connecting plate 115 extends along the plumb line and is perpendicular to the plane formed by the idler frame 1, and the pin 41 is set perpendicular to the connecting plate 115, the idler frame 1 can rotate around the pin 41 in the conveying direction of the conveyor belt. This allows the idler frame 1 to adjust itself according to the material on the conveyor belt, thereby making the idler frame 1 suitable for various working conditions and increasing the flexibility of the idler frame 1.

[0098] Furthermore, refer to Figures 1 to 4 The connecting plate 115 is provided with reinforcing plates 116 located on both sides of the pin 41. The projection of the reinforcing plates 116 toward the connecting plate 115 at least covers the connection position between the connecting plate 115 and the top beam 11.

[0099] It is understandable that there are two reinforcing plates 116, each of which is fixedly connected to the connecting plate 115 by welding, and the reinforcing plate 116 is located on the side of the connecting plate 115 away from the top beam 11.

[0100] Since the reinforcing plate 116 is located on the connecting plate 115, and the projection of the reinforcing plate 116 toward the connecting plate 115 at least covers the connection position between the connecting plate 115 and the top beam 11, on the one hand, the reinforcing plate 116 can increase the structural strength of the connecting plate 115 to ensure the service life of the connecting plate 115. On the other hand, the reinforcing plate 116 can also increase the connection strength between the connecting plate 115 and the top beam 11 to a certain extent, avoiding the situation where the connecting plate 115 can deform in a direction away from the top beam 11, which would cause tearing at the connection position between the connecting plate 115 and the top beam 11, thereby ensuring the connection stability between the connecting plate 115 and the top beam 11.

[0101] Of course, in order to increase the connection stability between the connecting plate 115 and the top beam 11, a reinforcing plate 116 can be provided on the side of the connecting plate 115 facing the top beam 11. One side of the reinforcing plate 116 is fixedly connected to the connecting plate 115 by welding, and the other side of the reinforcing plate 116 is fixedly connected to the top beam 11 by welding. This increases the structural strength of the connecting plate 115 to ensure its structural strength, and also increases the connection stability between the connecting plate 115 and the top beam 11.

[0102] Furthermore, refer to Figures 1 to 4 A support plate 117 is provided on the side of the reinforcing plate 116 away from the connecting plate 115. The support plate 117 is arranged parallel to and spaced apart from the connecting plate 115. The pin 41 passes through the support plate 117. The adjusting rod 42 is located between the connecting plate 115 and the support plate 117, which can balance the force on the pin 41, thereby increasing the stability of the pin 41 and ensuring the stability of the roller frame 1.

[0103] It is understandable that the support plate 117 is located between the two reinforcing plates 116, and both ends of the support plate 117 are fixedly connected to the two reinforcing plates 116 by welding.

[0104] This application does not specify the connection method between the sling 3 and the adjusting rod 42. Preferably, refer to... Figures 1 to 4 One end of the adjusting rod 42 has an opening in a U-shaped plate 421 facing away from the adjusting rod 42. One end of the sling 3 is located inside the U-shaped plate 421 and is connected to the U-shaped plate 421 by fasteners. This increases the connection stability between the sling 3 and the adjusting structure 4, and reduces the installation difficulty of the sling 3, thereby improving the assembly efficiency of the sling 3 and thus the assembly efficiency of the belt conveyor. In other embodiments, the end of the adjusting rod 42 away from the pin 41 can also be provided with a fixing ring, and the steel cable is fixedly connected to the fixing ring by interlocking rings.

[0105] This application does not specify the structure of the fastener; see reference... Figure 3 Preferably, the fastener is a pin with an R-shaped locking pin, which reduces the difficulty of connecting the sling 3 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 3 and the U-shaped plate 421.

[0106] This application does not specify 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 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 make a stop engagement in the vertically downward direction.

[0107] In other embodiments, the adjustment structure 4 may also be a tightening screw buckle, with one end of the tightening screw buckle connected to the hoisting position and the other end of the tightening screw buckle connected to the steel cable, and the hoisting position is formed by a U-shaped rod fixedly connected to the top beam 11.

[0108] In a preferred embodiment, refer to Figure 1 and Figure 2 The top beam 11, the first connecting beam 12, and the second connecting beam 13 are all equipped with U-shaped rope clips 121 for longitudinal steel wire ropes to pass through. This allows multiple suspended roller devices suspended on the suspension device to be connected together by the longitudinal steel wire ropes passing through the U-shaped rope clips 121, thereby preventing multiple suspended roller devices from swinging relative to each other in the longitudinal direction and ensuring the stability of the belt conveyor.

[0109] It is understandable that each U-shaped rope clamp 121, together with its corresponding top beam 11, first connecting beam 12 or second connecting beam 13, forms a closed space for the wire rope to pass through.

[0110] It should be noted that after the longitudinal wire rope passes through the U-shaped rope clamp 121, the nut of the U-shaped rope clamp 121 can be tightened so that the U-shaped rope clamp 121 clamps the wire rope. The longitudinal wire rope connecting multiple suspended roller devices is connected to the steel structure support tower of the suspension device to achieve longitudinal fixation of the suspended roller device.

[0111] In a preferred embodiment, the idler assembly 2 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, reduce running resistance, and also increase the installation space for the idlers to facilitate their installation.

[0112] Of course, in other embodiments, multiple idlers are arranged in a row, and the force balance of the idler frame 1 in the vertical direction can be achieved by setting the central axis of the multiple idlers on the plane where the idler frame 1 is located, so as to facilitate the stability of the idler frame 1.

[0113] It is understood that the idler assembly 2 also includes a frame, the idler is installed on the frame, one end of the frame is fixedly connected to the first connecting beam 12, and the other end of the frame is fixedly connected to the second connecting beam 13. When multiple idlers are arranged in a row, the frame is directly fixedly connected to the first connecting beam 12 and the second connecting beam 13. When multiple idlers are divided into two rows, the frame is provided with two units corresponding to the two rows of idlers, and the two rows of idlers are located on both sides of the first connecting beam 12 and the second connecting beam 13 respectively. The first connecting beam 12 and the second connecting beam 13 are both provided with angle steel, and the two frames are located at both ends of the two angle steels and fixedly connected to the angle steels.
