Description

Technical Field

[0001] This utility model belongs to the field of material conveying technology, and relates to a bidirectional cableway belt conveyor. Background Technology

[0002] With the development of modern production, green and low-carbon practices have become the theme of our time. The investment and energy consumption issues arising from the operation of bulk material conveying systems have attracted widespread attention in the industry. Conventional belt conveyors can meet the requirements of green transportation, but they suffer from high initial investment, high operating resistance, and high operating costs, which are not conducive to reducing the bulk material logistics transportation costs for enterprises. Wheel-rail belt conveyors have large carrying capacity and low operating resistance, but under current technological conditions, they suffer from high operating noise and limited wheel-rail lifespan. Doppelmayr's cableway-type wheeled sidewall belt conveyor has high adaptability to terrain, but it requires a special conveyor belt with pulleys. Therefore, a new type of cableway-type belt conveyor that combines the characteristics of cableway conveyor technology and ordinary belt conveyor technology is needed. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a bidirectional cableway conveyor with the characteristics of high terrain adaptability, small footprint, low investment and operating costs, and the ability to realize bidirectional transportation.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A bidirectional cableway belt conveyor, comprising a conveying device, a drive device, and a circulating cableway system;

[0006] The conveying device includes a head roller, a tail roller, and a conveyor belt, which is wound around the head roller and the tail roller and overlaps to form a closed loop.

[0007] The drive device is located on the side of the head roller to drive the conveying device.

[0008] The circulating cableway system is located in the middle of the conveyor belt and includes a head detour device, a tail detour device, and several hangers. The head detour device and the tail detour device are connected by two parallel support cables. The tops of the hangers are slidably connected to the support cables by pulleys, and the bottoms are hooked to the underside of the conveyor belt, so that the conveyor belt is suspended from the support cables by the hangers and moves along the support cables by the hangers.

[0009] Optionally, in the bidirectional cableway conveyor according to the present invention, the head detour device is a horizontally arranged head detour wheel, the tail detour device is a horizontally arranged tail detour wheel, and the carrying cable is connected to the circumference of the head detour wheel and the tail detour wheel; the head detour wheel is also provided with a detour wheel drive device to drive the head detour wheel to rotate.

[0010] Optionally, according to the bidirectional cableway belt conveyor of the present invention, the circulating cableway system further includes a fixed bearing track, which is connected between the bearing cable and the head detour wheel and the tail detour wheel respectively, and the end of the fixed bearing track closer to the bearing cable is higher than the end farther from the bearing cable to form a height difference.

[0011] Optionally, in the bidirectional cableway conveyor according to the present invention, the fixed bearing track includes an integrally formed straight section and an arc section, the arc section being connected to the circumference of the head detour wheel and the tail detour wheel respectively, and the straight section being connected between the arc section and the bearing cable.

[0012] Optionally, in the bidirectional cableway conveyor according to the present invention, the extension line of the carrying cable is tangent to the circumference of the head detour wheel and the tail detour wheel.

[0013] Optionally, according to the bidirectional cableway belt conveyor of the present invention, the circulating cableway system further includes connecting cables, and several hangers are connected by the connecting cables to form an integral suspension structure.

[0014] Optionally, in the bidirectional cableway conveyor according to this utility model, the spacing between two adjacent hangers is equal.

[0015] Optionally, according to the bidirectional cableway conveyor of the present invention, the conveying device further includes a redirecting roller group, wherein a head redirecting roller and a tail redirecting roller are arranged parallel to each other on the side of the head roller and the tail roller.

[0016] The redirecting roller assembly is respectively disposed between the head roller and the head redirecting roller, and between the tail roller and the tail redirecting roller. The conveyor belt is sequentially wound around the head roller, the tail roller, the head redirecting roller, and the tail redirecting roller via the redirecting roller assembly, so that the conveying device forms two conveying channels with different conveying directions.

[0017] Optionally, according to the bidirectional cableway conveyor of the present invention, the conveying device further includes a set of ordinary idlers, which is located between the head roller, the head redirecting roller and the head detour device, and between the tail roller, the tail redirecting roller and the tail detour device, and is located on the underside of the conveyor belt to support the conveyor belt.

[0018] Optionally, according to the bidirectional cableway conveyor of the present invention, the conveying device further includes a cantilever idler group, which is located between the ordinary idler group and the head detour device and the tail detour device, and is located on the lower side of the conveyor belt, so as to avoid interference between the hanger and the ordinary idler group.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1) This utility model fully combines the characteristics of belt conveyor technology and cableway conveyor. A circulating cableway system is set between the head and tail rollers of the belt conveyor. The conveyor belt runs under the action of the drive device. When it moves to the middle, it cooperates with the circulating cableway system to drive the hanger to move along the carrying cable through the pulleys set on it, thereby realizing the conveying of the material carried on the conveyor belt. It has the advantages of small footprint, low initial investment cost, low conveying resistance and low operating cost.

[0021] 2) Compared with existing technologies, the conveyor belt of this utility model can be an ordinary conveyor belt. A circulating cableway system is set up on the basis of the original belt conveyor, which reduces the design and performance requirements of the conveyor belt.

[0022] 3) The conveyor belt of this utility model is redirected by multiple sets of redirecting rollers, so that the conveyor of this utility model can achieve bidirectional transportation without changing the transportation direction.

[0023] 4) The conveyor of this utility model adopts a cableway in the middle section, and the conveyor belt is suspended and supported by a circulating water cableway system. There is no need to set up a separate corridor in the middle transportation section, which can further reduce the total investment.

[0038] Example 1:

[0039] Please see Figures 1 to 7 As shown, this is a bidirectional cableway conveyor.

[0040] It includes a conveyor, a drive unit 1, and a circulating cableway system 5.

[0041] The conveying device includes a head roller 2, a tail roller 3, and a conveyor belt 4. The conveyor belt 4 is wound around the head roller 2 and the tail roller 3 and overlaps to form a closed loop.

[0042] The drive unit 1 is located on the side of the head roller 2 to drive the conveyor.

[0043] The circulating cableway system 5 is located in the middle of the conveyor belt 4, including a head detour device 9, a tail detour device 10, and several hangers 6. The head detour device 9 and the tail detour device 10 are connected by two parallel load-bearing cables 7. The tops of the several hangers 6 are slidably connected to the load-bearing cables 7 by pulleys 61, and the bottoms are hooked to the underside of the conveyor belt 4, so that the conveyor belt 4 is suspended from the load-bearing cables 7 by the hangers 6 and moves along the load-bearing cables 7 by the hangers 6.

[0044] like Figures 1-7As shown, the bidirectional cableway belt conveyor drives the head roller 2 to move the conveyor belt 4 through the drive device 1. At the head and tail sections of the conveyor, the conveyor belt 4 is supported by idler rollers, just like a conventional belt conveyor. However, in the middle section, the conveyor belt 4 is no longer supported by idler rollers, but by the hanger 6 suspended from the carrying cable 7. When the conveyor belt 4 moves, the static friction between it and the hanger 6 drives the hanger 6 to rotate counterclockwise horizontally along the carrying cable 7 through the pulley 61 set on it, thereby realizing the conveying of the material carried on the conveyor belt 4.

[0045] This utility model fully combines the characteristics of belt conveyor technology and cableway conveyor. A circulating cableway system 5 is set between the head and tail rollers 3 of the belt conveyor. Under the action of the drive device 1, the conveyor belt 4 drives the hanger 6 to move along the carrying cable 7 through the pulley 61 set on it, thereby realizing the conveying of the material carried on the conveyor belt 4. It has the advantages of saving space, low initial investment cost, low conveying resistance, and low operating cost.

[0046] Furthermore, the head detour device 9 is a horizontally arranged head detour wheel 15, and the tail detour device 10 is a horizontally arranged tail detour wheel 16. The carrying cable 7 is connected to the circumference of the head detour wheel 15 and the tail detour wheel 16. The head detour wheel 15 is also provided with a detour wheel drive device 17 to drive the head detour wheel 15 to rotate. In this embodiment, the head detour wheel 15 and the tail detour wheel 16 are located on the same horizontal line. Based on the original belt conveyor being able to drive the hanger 6 to move, this utility model also drives the head detour wheel 15 or the tail detour wheel 16 to rotate through the detour wheel drive device 17. Moreover, the rotation direction of the head detour wheel 15 should be consistent with the direction of the belt conveyor driving the hanger to move, thereby reducing the friction force from the hanger 6 on the conveyor belt 4 and ensuring the effective transport of the belt conveyor at the position of the central circulating cableway system 5.

[0047] Furthermore, the circulating cableway system 5 also includes a fixed support track 14, which is connected between the support cable 7 and the head detour wheel 15 and the tail detour wheel 16 respectively. The end of the fixed support track 14 closer to the support cable 7 is higher than the end farther away from the support cable 7 to form a height difference.

[0048] according to Figure 2 and Figure 5As shown, when the gantry 6 moves to a position close to the head detour wheel 15, a fixed bearing rail 14 is provided at the head detour wheel 15 to allow the gantry 6 to separate from the conveyor belt 4 and continue moving along the head detour wheel 15. The fixed bearing rail 14 overlaps with the bearing cable 7 at its ends, allowing the gantry 6 to smoothly transition from moving along the bearing cable 7 to moving along the fixed bearing rail 14. Furthermore, in this embodiment, the two ends of the fixed bearing rail 14 have a certain height difference. Compared to the end of the fixed bearing rail 14 furthest from the bearing cable 7, the end of the fixed bearing rail 14 closer to the bearing cable 7 is higher. This ensures that as the gantry 6 moves along the fixed bearing rail 14, its height decreases as the height of the fixed bearing rail 14 decreases, until the gantry 6 can completely detach from the conveyor belt 4 and will not interfere with the conveyor belt 4 when rotating along the fixed bearing rail 14. Similarly, the working process of the conveyor in other transition sections of the circulating cableway system is similar and will not be described further.

[0049] Furthermore, due to the presence of the fixed bearing track 14, the bottom of the hanger 6 can be configured as a hook-shaped structure. When the hanger 6 is located on the bearing cable 7, the hook-shaped structure at the bottom can hook the conveyor belt 4 to prevent the conveyor belt 4 from detaching from the hanger 6. As the conveyor belt 4 continues to transport, after passing through the fixed bearing channel, the bottom of the hanger 6 and the conveyor belt 4 move away from each other. The highest point of the hook-shaped structure at the bottom of the hanger 6 should be less than the height difference of the fixed bearing track 14, thereby ensuring that the hook-shaped structure at the bottom of the hanger 6 can detach from the bottom of the conveyor belt 4 and, with the rotation of the head detour wheel 15 or the tail detour wheel 16, enter the next suspension of the conveyor belt 4.

[0050] Furthermore, the fixed load-bearing track 14 includes an integrally formed straight section 141 and an arc-shaped section 142. The arc-shaped section 142 is connected to the circumference of the head detour wheel 15 and the tail detour wheel 16, respectively, and the straight section 141 is connected between the arc-shaped section 142 and the load-bearing cable 7. In implementation, since the fixed load-bearing track 14 is an integral structure, the arc-shaped section enables the transition transport between the straight section 141 and the head detour wheel 15 or the tail detour wheel 16. Moreover, the center of the arc of the arc-shaped section should be located at the same point as the center of the head detour wheel 15 or the tail detour wheel 16, thereby facilitating the assembly between the arc-shaped section and the head detour wheel 15 or the tail detour wheel 16.

[0051] Furthermore, the extension line of the load-bearing cable 7 is tangent to the circumference of the head detour wheel 15 and the tail detour wheel 16, so as to fix the load-bearing rail 14 to connect the load-bearing cable 7 to the head detour wheel 15 or the tail detour wheel 16, and avoid mismatch at the connection, which would cause the sliding of the hanger 6 to be obstructed.

[0052] Furthermore, the circulating cableway system 5 also includes connecting cables 8, through which several hangers 6 are connected to form an integral suspension structure. In implementation, the hangers 6 are connected into a single structure via the connecting cables 8. When one hanger 6 slides, it will cause all hangers 6 to move synchronously via the connecting cables 8, and all hangers 6 will move at essentially the same speed. Combined with the head detour wheel 15 drive device 1 and the conveyor belt 4, the entire hanger 6 operates stably on the load-bearing cable 7, avoiding speed differences between individual hangers 6.

[0053] For example, as mentioned above, the fixed support track 14 has a certain height difference. The hangers 6 moving from high to low will gain additional acceleration due to their own gravity, while the hangers 6 moving from low to high will decelerate due to their own gravity, and may even be unable to effectively transition from the fixed support track 14 to the support cable 7. This situation will cause the hangers 6 to accumulate on the head detour wheel 15 or the tail detour wheel 16, requiring the subsequent hangers 6 to be pushed and squeezed in the sliding direction one by one, which seriously affects the normal operation of the conveyor belt 4. However, the connecting cable 8 in this utility model connects all the hangers 6 into a whole, which can effectively solve this problem.

[0054] Furthermore, the spacing between two adjacent hangers 6 is equal. In implementation, setting hangers 6 with equal spacing, combined with the connecting cable 8, makes the overall suspension of the conveyor belt 4 by the hangers 6 relatively stable, avoiding local dents in the conveyor belt 4 or even material falling off the conveyor belt 4 due to excessive spacing between hangers 6.

[0055] Example 2:

[0056] Then according to Figures 1 to 3 ,as well as Figure 7 As shown, the conveying device also includes a redirecting roller assembly 11, with a head redirecting roller 12 and a tail redirecting roller 13 arranged parallel to each other on the sides of the head roller 2 and the tail roller 3.

[0057] The redirecting roller assembly 11 is respectively set between the head roller 2 and the head redirecting roller 12, and the tail roller 3 and the tail redirecting roller 13. The conveyor belt 4 is wound around the head roller 2, the tail roller 3, the head redirecting roller 12 and the tail redirecting roller 13 in sequence through the redirecting roller assembly 11, so that the conveying device forms two conveying channels with different conveying directions.

[0058] Specifically, such as Figure 7The diagram shows the connection between the redirecting roller assembly 11 and the head roller 2. The conveyor belt 4 is wound around another set of conveying channels by multiple sets of pulleys 61. Since both sets of conveying channels use the same conveyor belt 4 and the conveying direction of the conveyor belt 4 is constant, the conveyor belt 4 in this invention can achieve bidirectional conveying. That is, in this embodiment, the material can be moved from one end of the head roller 2 to one end of the tail roller 3, or the material can be moved from one end of the tail redirecting roller 13 to one end of the head redirecting roller 12, and the conveying speed of the two conveying channels is the same.

[0059] Furthermore, in the circulating cableway system 5 of this utility model, the two supporting cables 7 are located on the upper side of the two sets of conveying channels respectively, and the hanger 6 can suspend the conveyor belts 4 on the two sets of conveying channels, so that the overall force of the circulating cableway system 5 is more balanced, avoiding the problem of easy damage or tilting due to force on one side. At the same time, it also avoids the cost problem of traditional two independent conveying channels, which make it difficult to ensure consistent conveying speed and require multiple sets of drive equipment.

[0060] Furthermore, the conveying device also includes a set of ordinary idler rollers 19, which is located between the head roller 2, the head redirecting roller 12 and the head detour device 9, and between the tail roller 3, the tail redirecting roller 13 and the tail detour device 10, and is situated below the conveyor belt 4 to support it. This invention reduces the need for ordinary idler roller sets 19 by using a circulating cableway system 5, thus mitigating the large footprint of traditional belt conveyors. However, the stability at the positions of the head roller 2 and the tail roller 3, which are analogous to the ends of a bridge structure, should be improved.

[0061] Furthermore, such as Figure 5 As shown, the conveying device also includes a cantilevered idler assembly 18, which is located between the ordinary idler assembly 19 and the head detour device 9 and tail detour device 10, and is situated below the conveyor belt 4 to avoid interference between the hanger 6 and the ordinary idler assembly 19. The difference from the ordinary idler assembly 19 is that the cantilever structure (extending 30%-50% in length than the ordinary idler assembly 19) shifts the idler support point outward, creating a geometric interference avoidance space. This increases the minimum safe clearance between the hanger 6 and other components and the running track of the conveyor belt 4 from 20mm in the traditional structure to over 80mm, ensuring that the bottom of the hanger 6 can completely detach from the conveyor belt 4 and, with further sliding, enter the circumference of the head detour wheel 15 or the tail detour wheel 16.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
