Description

Technical Field

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

[0002] With the rapid development of production technology, green and low-carbon has become an unavoidable theme. In this context, as an important link in industrial production, the energy consumption problem of bulk material conveying system in its operation process has become increasingly prominent, attracting widespread attention from both inside and outside the industry. In order to respond to the call for energy conservation and emission reduction, improve production efficiency and reduce operating costs, it is particularly important to develop new and efficient bulk material conveying systems.

[0003] As a new type of conveyor belt machine, the wheel-rail conveyor has shown great potential in the field of bulk material transportation due to its unique operating principle and structural design. The core of this model is to use a trolley to carry the conveyor belt, and use the power of the conveyor belt to drive the trolley to run on the track, so as to achieve fast and stable transportation of materials. This design not only improves the transportation efficiency, but also reduces energy consumption and environmental pollution, which is in line with the development trend of green and low-carbon.

[0004] As one of the important components of the wheel-rail belt conveyor, the performance and structure of the trolley have a crucial impact on the overall performance of the conveyor. However, in the prior art, the conveyor belt and the trolley are usually designed with their own independent circular motion trajectories. In order to facilitate the separation or combination of the conveyor belt and the trolley during operation, an open trolley and a transition-flipped conveyor belt are often used, and the separation and combination of the conveyor belt and the trolley are achieved by repeatedly flipping the conveyor belt. This structure also has a series of problems in the current production and transportation process.

[0005] There is a significant limitation in the current wheel-rail conveyor technology, especially at the critical position where the trolley changes direction at the head and tail. Specifically, the conveyor belt cannot return directly and smoothly to the support surface of the trolley at these positions. In order to overcome this technical obstacle, an extremely complex and long-extending turning mechanism must be designed and installed to ensure that the conveyor belt can be accurately repositioned to the support surface of the trolley after passing the turning point through multiple turnings, thereby maintaining the continuity and stability of the entire conveying system. However, this solution not only greatly 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 and shortens its normal service life; because the conveyor belt requires a long transition turning section to achieve re-combination with the trolley, the overall length of the conveyor is increased, occupying more production space, and bringing additional burdens to 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, an object of the present invention is to provide a trolley and a wheel-rail belt conveyor with the trolley, which can reduce equipment investment and extend the service life of the conveyor belt.

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

[0009] A trailer comprises a frame, wherein a support surface for supporting a conveyor belt is arranged on the frame, and the support surface is tilted at both ends along the width direction of the conveyor belt, and is in the shape of a groove with an opening facing a side away from the frame; and further comprises a rocker mechanism, one end of which is horizontally rotatably connected to the tilted end of the support surface, and when the rocker mechanism is rotated to a closed state, it forms a surrounding structure with the groove-shaped support surface.

[0010] Optionally, one end of the rocker mechanism close to the supporting surface is a rotating shaft end, and a toggle mechanism is also provided on the rotating shaft end; the toggle mechanism includes a toggle rod with one end vertically connected to the rocker mechanism, and a toggle wheel is provided at the other end of the toggle rod; the toggle rod and the toggle wheel are coaxially arranged.

[0011] Optionally, a limiting mechanism for limiting the rotation range of the rocker mechanism is provided on the rotating shaft end of the rocker mechanism.

[0012] Optionally, the rocker mechanism includes a first rocker and a second rocker respectively arranged at two raised ends of the support surface.

[0013] Optionally, a reset element is also provided on the rotating shaft end of the rocker mechanism.

[0014] Optionally, the frame is further provided with a first connecting mechanism for connecting adjacent frames.

[0015] A wheel-rail belt conveyor comprises a first roller and a second roller arranged side by side, and a conveyor belt arranged around the first roller and the second roller, any of the above-mentioned trolleys is arranged inside the ring of the conveyor belt, and wheel groups are arranged on both sides of the frame along the width direction of the conveyor belt; the trolley runs on the track through the wheel group, and the track comprises an upper running track and a lower running track parallel to the conveyor belt; a reversing mechanism connecting the upper running track and the lower running track is arranged at both ends of the track, and a groove rail matched with the toggle wheel is arranged around the outer side of the reversing mechanism, and the toggle wheel enters the groove rail and contacts the side wall of the groove rail, so that the toggle wheel drives the toggle rod and the rocker to rotate, thereby realizing the opening and closing of the rocker mechanism.

[0016] Optionally, the reversing mechanism comprises a 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 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 track is arranged on a support frame, and a second connecting mechanism is arranged on the outer side 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] The beneficial effects of the present invention are:

[0020] The invention eliminates the turning mechanism, avoids the wear of the conveyor belt caused by multiple turnings, and reduces the equipment investment cost.

[0021] The present invention can open or close the trolley as needed without the aid of additional power. On the one hand, it is convenient for the conveyor belt to be separated from the trolley as needed. On the other hand, it is convenient for the separated conveyor belt to be quickly returned to the trolley support surface as needed, so as to avoid the setting of a complex and long-distance turning mechanism, reduce equipment investment, and increase the service life of the conveyor belt.

[0022] The support frame of the present invention and the device installed thereon can be hung on the cable through the second connecting mechanism (i.e., the hanging ear). By adopting the cable hanging method, it is no longer necessary to set up a separate corridor, which can further reduce the total equipment investment.

[0023] The trailer coupling rope of the present invention can also be used as a traction rope under the action of the driving device to drive the trailer to make reciprocating rotational motion together with the conveyor belt supported on the trailer. In this way, the role of the trailer coupling rope can be fully utilized and the requirements for the strength of the conveyor belt can be further reduced.

The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting the present invention. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0042] See also Figures 1 to 11 , is a trolley 5, including a frame 51, on which a support surface for supporting a conveyor belt 3 is provided, the support surface is tilted at both ends along the width direction of the conveyor belt 3, and is in the shape of a groove with an opening facing the side away from the frame 51; and also includes a rocker mechanism 53, one end of the rocker mechanism 53 is rotated along the horizontal plane of the frame 51 and connected to the tilted end of the support surface, and when the rocker mechanism 53 is rotated to a closed state, it forms a surrounding structure with the groove-shaped support surface. In the load-bearing section where the belt conveyor is located above, the groove-shaped support 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, etc., and in the return section where the belt conveyor is located below, the groove-shaped support surface of the trolley 5 opens downward, and the rocker of the enclosed structure plays a role in supporting the return conveyor belt 3.

[0043] When the rocker mechanism 53 rotates to the maximum angle, the groove-shaped support surface is completely open, so that the conveyor belt 3 can completely leave the trailer 5, or return to the trailer 5. The rocker mechanism 53 includes a first rocker 531 and a second rocker 532 respectively arranged at two tilted ends of the support surface. In some embodiments of the present invention, the first rocker 531 and the second rocker 532 are symmetrically arranged.

[0044] The frame 51 is also provided with a first connection mechanism 40, which is locked by a connection rope 4 to connect the first connection mechanism 40 of the frame 51 of the adjacent trailer 5. When there are a plurality of trailers 5, they are connected to form a trailer 5 group. The frame 51 is provided with a wheel group 52 along the width direction of the conveyor belt 3. In some embodiments of the present invention, the first connection mechanism 40 is in the form of a hanging ear. In actual applications, the form of the first connection mechanism 40 can be adjusted as needed.

[0045] One end of each rocker close to the supporting surface is a rotating shaft end, and the other end is a free end.

[0046] A limiting mechanism is arranged on the rotating shaft end of each rocker to limit the rotation range of the rocker; wherein the limiting mechanism comprises a first stopper and a second stopper respectively arranged on both sides of the rotation range of the rocker.

[0047] A toggle mechanism 55 is also provided on the rotating shaft end of each rocker to drive the rocker to rotate around it. The toggle mechanism 55 includes a toggle rod 551 with one end vertically connected to the rocker mechanism 53, and a toggle wheel 552 is provided at the other end of the toggle rod 551; the toggle rod 551 and the toggle wheel 552 are coaxially arranged. After passively rotating, the toggle wheel 552 drives the toggle rod 551 to rotate around its axis, and the toggle rod 551 drives the rocker to rotate horizontally around its rotating shaft end to leave its closed state.

[0048] A reset element 54 is also provided on the rotating shaft end of each rocker so that the rocker mechanism 53 always tends to return to the closed state. Figure 7 In some embodiments of the present invention, the reset element 54 is preferably a torsion spring.

[0049] 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 many times before it can be re-combined at 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.

[0050] like Figures 1 to 11As shown, a wheel-rail belt conveyor comprises a first roller 1 and a second roller 2 arranged side by side, and a conveyor belt 3 arranged around the first roller 1 and the second roller 2, any of the above-mentioned trolleys 5 are arranged inside the annular ring of the conveyor belt 3, and wheel groups 52 are arranged on both sides of the frame 51 along the width direction of the conveyor belt 3; the trolley 5 runs on the track 7 through the wheel group 52, and the track 7 comprises an upper running track 71 and a lower running track 72 parallel to the conveyor belt 3, wherein the upper running track 71 is located in the load-bearing section, and the lower running track 72 is located in the return section, and the upper running track 71 and the lower running track 72 are arranged in pairs in parallel; as shown Figure 5 , 6 As shown, a reversing mechanism 6 is provided at both ends of the track 7 to connect the upper running track 71 and the lower running track 72. A groove rail 9 matching with the toggle wheel 552 is provided around the outer side of the reversing mechanism 6. The toggle wheel 552 enters the groove rail 9 and contacts the side wall of the groove rail 9, so that the toggle wheel 552 drives the toggle rod 551 and the rocker to rotate, and the first rocker 531 and the second rocker 532 move away from or close to each other, so as to realize the opening and closing of the rocker mechanism 53. The track 7 can adopt a steel rail structure or a steel cable structure. Each toggle wheel 552 corresponds to a groove rail 9, so two groove rails 9 are provided around the outer side of each reversing mechanism 6.

[0051] The track 7 is arranged on the support wheel 81 of the support frame 8. The cross section of the support frame 8 is rectangular. The support wheel 81 is arranged on the inner side of the support frame 8 near the wheel set 52; Figure 1 , 2 As shown, several support frames 8 are sequentially arranged along the running direction of the conveyor belt 3. A second connecting mechanism 82 is arranged on the outside of each support frame 8. 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 is provided with 4 ears; the hanging ears are connected to the hanging ears by cables 10, so that several support frames 8 arranged side by side are connected as a whole; correspondingly, when each support frame 8 is provided with 4 hanging ears, 4 cables 10 are also provided. The supporting fixed end of the cable 10 belongs to the existing conventional technology, and therefore, it will not be further described in this embodiment. The number of support frames 8 can be increased, decreased, and adjusted according to the length of the conveyor.

[0052] The reversing mechanism 6 includes a reversing wheel 61 parallel to the axial direction of the first roller 1, and a first arc track 62 and a second arc track 63 are arranged in sequence around the outer side of the reversing wheel 61. The upper running track 71 is connected to the first arc track 62 through the transition track 12, and the lower running track 72 is connected to the second arc track 63 through the transition track 12. A short roller 13 is arranged at the bottom of the reversing mechanism 6, and the short roller 13 and the rocker mechanism 53 of the trolley 5 jointly support the conveyor belt 3 in the return section of the conveyor belt 3.

[0053] Since two tracks 7 are arranged side by side along the width direction of the conveyor belt 3, each track 7 needs to be equipped with a reversing wheel 61, so two reversing wheels 61 are coaxially arranged. A roller 14 is coaxially arranged between the two reversing wheels 61, and a connecting rope 4 is arranged around the outer side of the roller 14. The upper connecting rope 4 is connected to the trolley 5 of the load-bearing section, and the lower connecting rope 4 is connected to the trolley 5 of the return section; the rotation of the roller 14 can drive the trolley 5 on the connecting rope 4 to move.

[0054] The conveyor belt 3 is provided with a first tensioning device 17; the connecting rope 4 is provided with a second tensioning device 18, and the tension of the conveyor belt 3 and the connecting rope 4 is adjusted by the tensioning device to achieve a balanced and tensioned state.

[0055] A first driving device 15 for driving the drum to rotate is also provided.

[0056] 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 to protect against wind and rain and limit the scattering of transported materials.

[0057] The working process of the present invention is as follows: the wheel-rail belt conveyor drives the first roller 1 through the first driving device 15 to drive the conveyor belt 3 to move. Different from the traditional belt conveyor, the conveyor belt 3 is carried by a trolley 5 in the middle section. The trolleys 5 are connected front and back in sequence through the connecting rope 4 to form a trolley 5 group. The conveyor belt 3 passes through the trolley 5 group in sequence and drives the trolley 5 group to move along the track 7 by static friction. The trolley 5 is provided with a rocker mechanism 53 that can rotate around an axis perpendicular to the support surface of the trolley 5.

[0058] When the load-bearing section runs to the return section, the rockers are moved closer to each other under the action of the reset element 54, forming a closed state, and the conveyor belt 3 is wrapped in the surrounding structure of the trailer 5. Specifically, in the load-bearing section, the groove-shaped support surface of the frame 51 carries the conveyor belt 3; in the return section, the closed rocker mechanism 53 carries the conveyor belt 3.

[0059] 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 realizing the separation of the conveyor belt 3 and the trolley 5. Specifically, at the reversing mechanism 6, as the track 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, and 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.

[0060] 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 groove rail 9 until finally forming a closed state, so that the conveyor belt 3 returns to the trolley 5. Specifically, at the reversing mechanism 6, as the track 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, and the rockers on both sides gradually approach each other until finally forming a closed state. Accordingly, the conveyor belt 3 in the return section gradually transitions from being supported only by rollers to being supported jointly by short rollers 13 and the rockers in the closed state, and finally transitions to being supported only by the rockers on both sides.

[0061] Similarly, when the trolley 5 moves from the return section to the reversing section, the rockers gradually move away from each other and finally form an open state, realizing the process of separation of the conveyor belt 3 and the trolley 5, and its working process is similar to the working 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 closer to each other and finally form a closed state, realizing the process of the conveyor belt 3 returning to the trolley 5, and its working process is similar to the working process of the trolley 5 moving from the rear reversing section to the load-bearing section. Therefore, they are not repeated here.

[0062] Example 1

[0063] The roller 14 and the two reversing wheels 61 remain relatively stationary and cannot rotate relative to each other.

[0064] Example 2

[0065] like Fig.11 As shown, in some embodiments of the present invention, a second driving device 16 is also included for driving the roller 14 of the connecting rope 4 to rotate. The roller 14 is coaxial with the reversing wheel 61. The reversing wheel 61 cannot rotate, but the roller 14 can rotate relative to the reversing wheel 61. The second driving device 16 drives the roller 14 to rotate, thereby driving the trolley 5 to move, thereby solving the problem that the conveyor belt 3 alone cannot fully drive the trolley 5 to move under certain working conditions.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. 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 solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the present invention.
