Description

Technical Field

[0001] The invention belongs to the technical field of material transportation and relates to a wheel-rail belt conveyor with a movable running rail. Background Art

[0002] With the rapid development of production technology, green and low-carbon development has become an unavoidable theme. Against this backdrop, the energy consumption of bulk material conveying systems, a crucial component of industrial production, has become increasingly prominent, attracting widespread attention both within and outside the industry. To address the call for energy conservation and emission reduction, improve production efficiency, and reduce operating costs, the development of new, efficient bulk material conveying systems is crucial.

[0003] As a new type of belt conveyor, the wheel-rail conveyor demonstrates tremendous potential in bulk material conveying thanks to its unique operating principle and structural design. The core of this machine is a trolley that carries the conveyor belt, which is then driven by the belt's power to move along the track, enabling rapid and stable material transport. This design not only improves conveying efficiency but also reduces energy consumption and environmental pollution, aligning with the development trend of green and low-carbon development.

[0004] As a key component of a wheel-rail belt conveyor, the performance and structure of the trolley crucially impact the overall performance of the conveyor. However, existing technologies typically design the conveyor belt and trolley with independent, circular motion paths. To facilitate the separation and connection of the conveyor belt and trolley during operation, an open trolley and a transitional, flipping conveyor belt are often used. This structure, which repeatedly flips the conveyor belt, allows the trolley to separate and connect. However, this structure presents a number of problems in current production and transportation processes.

[0005] The current wheel-rail conveyor technology has a significant limitation, especially at the critical locations where the trolleys reverse direction. Specifically, the conveyor belt cannot return directly and smoothly to the trolley's support surface at these locations. To overcome this technical obstacle, an extremely complex and long-reaching turning mechanism must be designed and installed. Through multiple turnings, the conveyor belt can be accurately repositioned to the trolley's support surface after passing the turning point, thereby maintaining the continuity and stability of the entire conveying system. However, this solution not only significantly increases the initial investment cost of the equipment, but also because the conveyor belt needs to undergo multiple turning actions during operation, this undoubtedly increases the energy consumption and wear of the conveyor belt, shortening its normal service life; because the conveyor belt requires a long transition turning section to achieve re-connection with the trolley, the overall length of the conveyor is increased, occupying more production space, and placing an additional burden on the company's production operations.

[0006] Therefore, there is an urgent need for a technical solution that can solve the problems existing in the above-mentioned prior art. Summary of the Invention

[0007] In view of this, the object of the present invention is to provide a wheel-rail belt conveyor with a movable running rail, which can realize a variety of driving modes of the trolley, give full play to the performance of each component of the conveyor, reduce the strength requirement of the conveyor belt, and reduce equipment investment.

[0008] In order to achieve the above object, the present invention provides the following technical solutions:

When the trolley runs from the running rail to the reversing mechanism, the toggle mechanism enters the groove rail and contacts its side wall to rotate, driving the rocker mechanism to rotate, thereby realizing the opening and closing of the trolley.

[0011] Optionally, the trolley includes a frame, which is provided with a supporting surface for supporting a conveyor belt, and the supporting surface is tilted at both ends along the width direction of the conveyor belt, forming a groove-shaped opening facing a side away from the frame; the rocker mechanism includes a first rocker and a second rocker respectively provided at the two tilted ends of the supporting surface; one end of each rocker is horizontally rotated and connected to the tilted end of the supporting surface, and when the first rocker and the second rocker are rotated close to each other to a closed state, they form a surrounding structure with the groove-shaped supporting surface; wheel groups are provided on both sides of the frame along the width direction of the conveyor belt, and the trolley runs on the running rail through the wheel groups.

[0012] Optionally, the frame is further provided with a first connecting mechanism for connecting adjacent frames.

[0013] Optionally, one end of the rocker mechanism close to the supporting surface is a rotating shaft end, and the toggle mechanism is arranged at the rotating shaft end; the toggle mechanism includes a toggle rod with one end vertically connected to the rocker mechanism, and the other end of the toggle rod is provided with a toggle wheel; the toggle rod and the toggle wheel are coaxially arranged; when the trolley runs from the running rail to the reversing mechanism, the toggle wheel enters the groove rail and contacts its side wall and rotates, driving the toggle rod and the rocker to rotate, thereby realizing the opening and closing of the trolley.

[0014] Optionally, a limiting mechanism for limiting the rotation range of the rocker mechanism is provided on the rotating shaft end of the rocker mechanism; the limiting mechanism includes a first stopper and a second stopper respectively provided on both sides of the rotation range of the rocker mechanism.

[0015] Optionally, a reset element is further provided on the rotating shaft end of the rocker mechanism.

[0016] Optionally, the reversing mechanism includes a second reversing wheel parallel to the axial direction of the first roller, and a first arc-shaped track and a second arc-shaped track are sequentially arranged around the outer side of the second reversing wheel.

[0017] Optionally, the upper running track is connected to the first curved track via a transition track, and the lower running track is connected to the second curved track via a transition track.

[0018] Optionally, the running rail is arranged on a support frame, and a second connecting mechanism is provided on the outside of the support frame, which is connected to the second connecting mechanism through a cable, so that several support frames arranged side by side are connected as a whole.

[0019] Optionally, a first reversing wheel is further included, and the running rail is wound around the first reversing wheel, and the reversal of the running rail is achieved by the rotation of the first reversing wheel.

[0020] The beneficial effects of the present invention are:

[0021] At present, the tracks of existing wheel-rail belt conveyors can only provide load-bearing function, while the present invention provides a wheel-rail belt conveyor with a movable running rail. The running rail drives the running rail to perform a cyclic reciprocating rotational motion under the action of the first roller and the second roller, and then the running rail can drive the trolley to move along the running rail through friction; in the second case, the conveyor belt performs a cyclic reciprocating rotational motion under the action of the first roller and the second roller, and the conveyor belt can also drive the trolley to move along the running rail through friction; in the third case, the frames of several trolleys are connected by a connecting rope to form a trolley group, and under the drive of the third drive device and the action of the third roller, the connecting rope drives the trolley group to move on the running rail.

[0022] The present invention provides a variety of power drive modes, which can not only drive the trolley to move through the conveyor belt, but also drive the trolley to move through the running rails or connecting ropes, thereby achieving the purpose of transporting materials with the conveyor belt and giving full play to the performance of each component of the conveyor. Therefore, it can further reduce the strength requirements of the conveyor belt and reduce equipment investment.

[0037] See also Figures 1 to 7, is a wheel-rail belt conveyor with a movable running rail, comprising a first roller 19, a first drum 1, a second drum 2, and a second drum 20 arranged side by side in sequence, a conveyor belt 3 arranged around the first drum 1 and the second drum 2, and a running rail 7 arranged around the first roller 19 and the second roller 20; the running rail 7 comprises an upper running rail 71 and a lower running rail 72 parallel to the conveyor belt 3; a retractable trolley 5 is provided within the annular interior of the conveyor belt 3, and the trolley 5 runs on the running rail 7. The running rail 7 is wound around a first reversing wheel 22, and the direction of the running rail 7 is reversed by the rotation of the first reversing wheel 22. In some embodiments of the present invention, the running rail 7 may be a cable structure such as a wire rope or a steel cable.

[0038] The wheel-rail belt conveyor also includes a reversing mechanism 6 respectively overlapped with the upper running rail 71 and the lower running rail 72, and an arc-shaped groove rail 9 arranged around the outside thereof; the trolley 5 is provided with a toggle mechanism 55 and a rocker mechanism 53 connected to the toggle mechanism 55, and the toggle mechanism 55 drives the rocker to rotate around it; when the trolley 5 runs from the running rail 7 to the reversing mechanism 6, the toggle mechanism 55 enters the groove rail 9 and contacts its side wall and rotates, driving the rocker mechanism 53 to rotate, thereby realizing the opening and closing of the trolley 5.

[0039] The upper running rail 71 is located in the load-bearing section, and the lower running rail 72 is located in the return section. The upper running rail 71 and the lower running rail 72 are parallel to each other and arranged in pairs. The single-side running rail 7 is composed of the upper running rail 71, the lower running rail 72 and the reversing mechanism 6 to form a closed-loop structure.

[0040] The reversing mechanism 6 includes a second reversing wheel 61 axially parallel to the first roller 1. A first curved track 62 and a second curved track 63 are sequentially arranged around the outer side of the second reversing wheel 61. The two curved tracks are parallel and arranged in pairs, so the second reversing wheels 61 are also arranged coaxially side by side in pairs. A third roller 14 is coaxially disposed between the two coaxially arranged second reversing wheels 61, and a connecting rope 4 is arranged around the outer side of the third roller 14. In some embodiments of the present invention, the third roller 14 and the second reversing wheel 61 remain relatively stationary and cannot rotate relative to each other. In other embodiments of the present invention, the third roller 14 and the second reversing wheel 61 can rotate relative to each other. In this case, the reversing wheels cannot rotate, but the third roller 14 can rotate relative to the second reversing wheel 61, thereby driving the trolley 5 to move, solving the problem that the conveyor belt 3 alone cannot fully drive the trolley 5 under certain working conditions.

[0041] The upper running track 71 is connected to the first curved track 62 via the transition track 12, and the lower running track 72 is connected to the second curved track 63 via the transition track 12. A short roller 13 is provided at the bottom of the reversing mechanism 6. The short roller 13 and the rocker mechanism 53 of the trolley 5 jointly support the conveyor belt 3 during the return section of the conveyor belt 3.

[0042] The trolley 5 includes a frame 51 , which is provided with a support surface for supporting the conveyor belt 3 . The support surface is tilted at both ends along the width of the conveyor belt 3 , forming a groove-like shape with its opening facing away from the frame 51 . The rocker mechanism 53 includes a first rocker 531 and a second rocker 532 , respectively disposed at the two tilted ends of the support surface. One end of each rocker is horizontally connected to the tilted end of the support surface. When the first rocker 531 and the second rocker 532 rotate toward each other to a closed state, they form a surrounding structure with the groove-like support surface. Wheel assemblies 52 are provided on both sides of the frame 51 along the width of the conveyor belt 3 , and the trolley 5 travels on the running rails 7 via the wheel assemblies 52 . In some embodiments of the present invention, the first rocker 531 and the second rocker 532 are arranged symmetrically.

[0043] In the load-bearing section where the belt conveyor is located above, the groove-shaped supporting surface of the trolley 5 opens upward, and the enclosed structure can effectively prevent the conveyor belt 3 carried on the trolley 5 from being blown out of the trolley 5 by strong winds. In the return section where the belt conveyor is located below, the groove-shaped supporting surface of the trolley 5 opens downward, and the rocker of the enclosed structure serves to support the return conveyor belt 3.

[0044] The frame 51 is also provided with a first coupling mechanism 40. The first coupling mechanism 40 of the frame 51 of an adjacent trailer 5 is locked by a coupling rope 4 to connect the two. When multiple trailers 5 are provided, they are connected to form a group of trailers 5. In some embodiments of the present invention, the first coupling mechanism 40 is in the form of a hook. In actual application, the form of the first coupling mechanism 40 can be adjusted as needed.

[0045] The rocker mechanism 53 has one end near the support surface as the rotating shaft end, and the other end as the free end. A toggle mechanism 55 is located at the rotating shaft end. The toggle mechanism 55 includes a toggle lever 551, one end of which is vertically connected to the rocker mechanism 53, and a toggle wheel 552 at the other end. The toggle lever 551 and toggle wheel 552 are coaxially arranged. Upon contact and passive rotation, the toggle wheel 552 drives the toggle lever 551 to rotate about its axis, which in turn drives the rocker 551 to rotate horizontally about its rotating shaft end, releasing it from its closed state. Each toggle wheel 552 corresponds to a grooved track 9, so two grooved tracks 9 are arranged around the outside of each reversing mechanism 6.

[0046] When the trolley 5 moves from the running rail 7 to the reversing mechanism 6, the toggle wheel 552 enters the groove rail 9 and contacts its side wall, causing it to rotate, driving the toggle lever 551 to rotate around its axis. The toggle lever 551 drives the rocker to rotate horizontally around its rotation axis end, causing the two rockers to move closer to or away from each other, thereby opening and closing the trolley 5. When the rocker mechanism 53 rotates to the maximum angle, the grooved support surface is completely open, allowing the conveyor belt 3 to completely separate from the trolley 5 or return to the trolley 5.

[0047] A limit mechanism is provided on the rotating shaft end of the rocker mechanism 53 to limit the rotation range of the rocker mechanism 53; the limit mechanism includes a first stopper and a second stopper respectively provided on both sides of the rotation range of the rocker mechanism 53. A reset element 54 is also provided on the rotating shaft end of the rocker mechanism 53 to ensure that the rocker mechanism 53 always has a tendency to return to the closed state. The closed state is as follows: Figure 6 In some embodiments of the present invention, the reset element 54 is preferably a torsion spring.

[0048] The openable and closable trolley 5 helps the conveyor belt 3 to be quickly separated or combined with the trolley 5 as needed, thereby avoiding the problem that the conveyor belt 3 needs to be turned over multiple times before it can be re-combined in the appropriate position, effectively shortening the length of the turning transition section of the conveyor belt 3, increasing the service life of the conveyor belt 3, and reducing equipment investment.

[0049] The track is set on the support wheel 81 of the support frame 8. The cross-section of the support frame 8 is rectangular, and the support wheel 81 is set on the inner side of the support frame 8 near the wheel group 52. Several support frames 8 are sequentially arranged along the running direction of the conveyor belt 3. A second connecting mechanism 82 is set on the outer side of each support frame 8. The second connecting mechanism 82 is connected to the second connecting mechanism 82 by a cable 10, so that several support frames 8 arranged side by side are connected as a whole. In some embodiments of the present invention, the second connecting mechanism 82 is a hanging ear, which is symmetrically arranged on the two outer sides of the support frame 8, and there are four hanging ears. Correspondingly, there are also four cables 10. The support and fixed end of the cable 10 belongs to the existing conventional technology and is therefore not further described in this embodiment.

[0050] A top cover 11 is provided on the side of the support frame 8 away from the conveyor belt 3. The top cover 11 covers the tops of several support frames 8, plays a role in shielding against wind and rain and limiting the scattering of transported materials. The number of support frames 8 can be increased or decreased and adjusted according to the length of the conveyor.

[0051] The running rail 7 is equipped with a first tensioning device 21, which tensions the running rail 7. The conveyor belt 3 is equipped with a second tensioning device 17, which tensions the conveyor belt 3. The connecting rope 4 is equipped with a third tensioning device (not shown in the drawings), which tensions the connecting rope 4. The tensioning devices adjust the tension of the conveyor belt 3, running rail 7, and connecting rope 4 to achieve a balanced and tensioned state.

[0052] The first roller 19 is equipped with a first driving device 23 for driving its rotation, and the first drum 1 is equipped with a second driving device 15 for driving its rotation; the third roller 14 is equipped with a third driving device (not shown in the figure) for driving its rotation.

[0053] The working process of the present invention is briefly described as follows:

[0054] The wheel-rail belt conveyor drives the first roller 1, which in turn drives the conveyor belt 3, via a third drive unit (not shown). A trolley 5 supports the conveyor belt 3 in its middle section. The trolleys 5 are connected in sequence by connecting ropes 4 to form a trolley group 5. The conveyor belt 3 passes through the trolley group 5, and static friction drives the trolley group 5 along the track. The trolleys 5 are equipped with a rocker mechanism 53 that can rotate about an axis perpendicular to the support surface of the trolley 5.

[0055] When the load-bearing section moves to the return section, the rockers move closer to each other under the action of the reset element 54, forming a closed state, wrapping the conveyor belt 3 within the surrounding structure of the trailer 5. Specifically, in the load-bearing section, the grooved support surface of the frame 51 supports the conveyor belt 3; in the return section, the closed rocker mechanism 53 supports the conveyor belt 3.

[0056] When the trolley 5 moves from the load-bearing section to the reversing section, the rocker mechanism 53 provided on the trolley 5 gradually moves away from each other under the action of the groove rail 9, forming an open state, and separating the conveyor belt 3 from the trolley 5. Specifically, at the reversing mechanism 6, as the trajectory of the groove rail 9 changes, the toggle wheel 552 on the rocker mechanism 53 contacts the side wall of the groove rail 9 and rotates, thereby driving the rockers on both sides to rotate. The rockers on both sides move away from each other, realizing the opening of the trolley 5, and then the conveyor belt 3 separates from the trolley 5 and continues to move forward.

[0057] When the trolley 5 moves from the reversing section to the return section, the rocker mechanism 53 provided on the trolley 5 gradually approaches each other under the action of the grooved rail 9 until it finally forms a closed state, allowing the conveyor belt 3 to return to the trolley 5. Specifically, at the reversing mechanism 6, as the trajectory of the grooved rail 9 changes, the toggle wheel 552 on the rocker mechanism 53 contacts the sidewall of the grooved rail 9 and rotates, thereby driving the rockers on both sides to rotate. The rockers on both sides gradually approach each other until they finally form a closed state. Accordingly, on the return section, the conveyor belt 3 gradually transitions from being supported solely by rollers to being supported jointly by the short rollers 13 and the closed rockers, and finally to being supported solely by the rockers on both sides.

[0058] Similarly, when the trolley 5 moves from the return section to the reversing section, the rockers gradually move away from each other, eventually forming an open state, achieving separation of the conveyor belt 3 from the trolley 5. This process is similar to the process of the trolley 5 moving from the load-bearing section to the reversing section. When the trolley 5 moves from the reversing section to the load-bearing section, the rockers gradually move toward each other, eventually forming a closed state, achieving return of the conveyor belt 3 to the trolley 5. This process is similar to the process of the trolley 5 moving from the rear reversing section to the load-bearing section. Therefore, no further description will be given.

[0059] Specifically, in Example 1, the conveyor belt 3 rotates back and forth under the action of the first roller 1, and the conveyor belt 3 drives the trolleys 5 along the running rails 7 through friction. In Example 2, the running rails 7 rotate back and forth under the action of the first roller 19, and the running rails 7 drive the trolleys 5 along the running rails 7 through friction. In Example 3, the connecting rope 4 rotates back and forth under the action of the third roller 14, and the connecting rope 4 connects the connecting structure of each trolley 5, thereby driving the group of trolleys 5 to move along the running rails 7. In Example 4, the conveyor belt 3, running rails 7, and connecting rope 4 cooperate with each other to drive the trolleys 5 along the running rails 7.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions, which should all be included in the scope of the claims of the present invention.
