In order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of actual products. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

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.

[0032] See also Figure 1 to Figure 4, which is a steel cable belt conveyor provided by the present invention. The first roller 7 and the second roller 10 are respectively arranged at both ends of the steel cable belt conveyor. The annular transmission belt 4 is wound on the first roller 7 and the second roller 10. Two annular traction wire ropes 3 are respectively wound on the first roller 7 and the second roller 10 and arranged on both sides of the transmission belt 4 to form a stable conveying channel; multiple tape trolleys 5 are arranged on the traction wire rope 3 at intervals and move synchronously with it, and each tape trolley 5 is provided with a supporting groove 19 for limiting the shape of the transmission belt 4; the first roller 7 and the second roller 10 are both provided with a reversing device 12 for changing the carrying relationship between the tape trolley 5 and the traction wire rope 3, and the tape trolley 5 is placed upright or hung upside down on the traction wire rope 3 through the reversing device 12, so that the supporting groove 19 of the tape trolley 5 always faces the transmission belt 4.

[0033] In order to further enhance the structural stability of the steel cable belt conveyor, the present invention arranges traction steel wire ropes 3 in parallel on both sides of the transmission belt 4. The two traction steel wire ropes 3 are also wound in a ring-shaped manner on the first roller 7 and the second roller 10 to form a parallel structure with the transmission belt 4, which not only enhances the overall bearing capacity of the steel cable belt conveyor, but also effectively prevents the transmission belt 4 from deviating during operation by dispersing the force.

[0034] Furthermore, a plurality of tape carriages 5 are installed at equal intervals along the length direction of the traction wire rope 3. The tape carriages 5 keep synchronous movement with the traction wire rope 3 through the annular groove on the guide wheel 16, thereby ensuring the stability of the transmission tape 4 during the transportation process. Each tape carriage 5 is provided with a supporting groove 19, and the transmission tape 4 is placed in the supporting groove 19. The supporting groove 19 limits the shape of the transmission tape 4 to prevent it from being deformed or offset during operation. This design not only improves the transportation efficiency, but also significantly extends the service life of the transmission tape 4.

[0035] Furthermore, the supporting groove 19 is arranged on the bottom frame 20 of the tape trolley 5, and at least one clamping arm group is arranged on the two sides of the bottom frame 20 parallel to the transmission tape 4, and each clamping arm group has two clamping arms 13 distributed opposite to each other, and each clamping arm 13 is hinged to the bottom frame 20, and its free end pivots around the corresponding hinge point driven by its own gravity. When the tape trolley 5 is placed on the traction wire rope 3, the clamping arm 13 rotates in the direction away from the transmission tape 4 due to the action of gravity, and the two clamping arms 13 are in an open state, so that the transmission tape 4 can be placed stably in the supporting groove 19, ensuring the stability and reliability during the conveying process. When the tape trolley 5 is hung upside down on the traction wire rope 3, the clamping arm 13 rotates in the direction close to the transmission tape 4 due to the action of gravity, and the two clamping arms 13 are in a closed state, so that the transmission tape 4 is placed on the two clamping arms 13, preventing the transmission tape 4 from falling off in the upside-down state, thereby improving the safety of the conveying system. Since the clamping arm 13 rotates by its own gravity, no additional driving device or complex control system is required, which makes the structure of the entire steel cable belt conveyor simpler and the manufacturing and maintenance costs lower.

[0036] Furthermore, in order to ensure the synchronous movement of the belt trolley 5 and the traction wire rope 3, the present invention also adds a guide wheel 16 on the bottom plate frame 20 of the belt trolley 5. The annular groove on the guide wheel 16 is closely matched with the traction wire rope 3, and the seamless connection and synchronous movement between the two are achieved through physical clamping. This design not only simplifies the connection structure of the belt trolley 5 and the traction wire rope 3, but also greatly improves the operation efficiency and stability of the conveyor.

[0037] Figure 5 The structural diagram of the reversing device of the steel cable belt conveyor provided by the present invention is shown below in combination with Figure 5 The reversing device 12 will be further described.

[0038] Furthermore, if Figure 5 As shown, in order to solve the adaptability problem of the tape trolley 5 in different operating positions and directions, the present invention sets a reversing device 12 at the first roller 7 and the second roller 10. The reversing device 12 can adjust the carrying relationship between the tape trolley 5 and the traction wire rope 3, and realize the flexible switching of the tape trolley 5 from the upright state to the inverted state. Specifically, the reversing device 12 is a columnar body, and the first spiral roller 15 is respectively provided on the two end surfaces thereof, and the first spiral roller 15 is provided with a spiral groove for winding the traction wire rope 3; the traction wire rope 3 is wound on the first spiral roller 15 and then wound to the corresponding first roller 7 or the second roller 10 respectively, and the reversing device 12 is driven by the traction wire rope 3 to rotate synchronously with the first roller 7 and the second roller 10.

[0039] In order to enable the reversing device 12 to lift the tape trolley 5, the reversing device 12 can be arranged between the upper traction wire rope 3 and the lower traction wire rope 3, and a reversing ring groove 18 is provided on the cylindrical surface of the reversing device 12. In addition, a reversing slider 17 cooperating with the reversing ring groove 18 is also provided at the bottom of the tape trolley 5, and the depth of the reversing ring groove 18 is less than the height of the reversing slider 17, so as to ensure that the reversing device 12 can lift the tape trolley 5. Specifically, when the belt trolley 5 moves to the top of the reversing device 12, the reversing slider 17 is embedded in the reversing annular groove 18 to lift the belt trolley 5, so that the traction wire rope 3 is disengaged from the guide wheel 16, and the belt trolley 5 rotates synchronously with the reversing device 12; when the belt trolley 5 rotates to the bottom of the reversing device 12, the reversing slider 17 is disengaged from the reversing annular groove 18, and the belt trolley 5 falls to the traction wire rope 3, so that the traction wire rope 3 is clamped on the guide wheel 16, and the belt trolley 5 moves synchronously with the traction wire rope 3. This design ensures that the supporting groove 19 always faces the transmission belt 4, and can maintain effective support and shape restriction of the transmission belt 4 even during the reversing process, thereby further improving the stability and reliability of the conveying process.

[0040] Figure 6 The structural schematic diagram of the first roller of the steel cable belt conveyor provided by the present invention is shown below. Figure 6 The structure of the first roller 7 will be further described.

[0041] Furthermore, if Figure 6 As shown, the second spiral roller 21 is also provided on both sides of the first drum 7, and the second spiral roller 21 is provided with a spiral groove for winding the traction wire rope 3. The second spiral roller 21 is installed on both sides of the first drum 7 to form an integrated structure with the drum body. The surface of the second spiral roller 21 is processed with a spiral groove, and the traction wire rope 3 can be wound on the second spiral roller 21. When the first drum 7 rotates under the drive of the driving device, the second spiral roller 21 will also rotate synchronously, thereby driving the traction wire rope 3 and the transmission belt 4 to move continuously and smoothly. This structural design not only realizes the efficient conversion of power transmission, that is, the rotational kinetic energy can be directly transmitted from the drum to the traction wire rope 3 and the transmission belt 4, reducing energy loss and improving transmission efficiency. At the same time, due to the close fit between the second spiral roller 21 and the traction wire rope 3, the overall stability of the steel cable belt conveyor is also enhanced, and the slippage or deviation of the traction wire rope 3 during the transmission process is effectively prevented. In addition, the setting of the second spiral roller 21 also provides convenience for the maintenance and adjustment of the steel cable belt conveyor. During actual use, if the tension of the traction wire rope 3 needs to be replaced or adjusted, the operator can easily install, disassemble or adjust the traction wire rope 3 through the second spiral roller 21 without large-scale disassembly of the entire steel cable belt conveyor, thereby greatly reducing maintenance costs and downtime.

[0042] In some embodiments, third spiral rollers (not shown in the figure) are also provided on both sides of the second drum 10 , and the traction wire rope 3 is wound on the third spiral rollers so that the traction wire rope 3 moves synchronously with the transmission belt 4 .

[0043] Furthermore, in order to drive the operation of the entire steel cable belt conveyor, the present invention is equipped with a driving device. The driving device directly acts on the first roller 7 or the second roller 10, and drives the overall movement of the transmission belt 4 and the traction wire rope 3 by rotating the driving roller. In addition, the frame system of the steel cable belt conveyor can include a first roller frame 8, a middle frame 2 and a second roller frame 11, and the above components together constitute a stable support system for the steel cable belt conveyor. The first roller 7 and the driving device can be arranged on the first roller frame 8, the second roller 10 is arranged on the second roller frame 11, the first roller frame 8 and the second roller frame 11 are connected by a load-bearing wire rope 1, and the middle frame 2 is suspended on the load-bearing wire rope 1. Among them, a wire rope support frame 14 is also installed at intervals on the middle frame 2 to further enhance the support for the traction wire rope 3 and ensure the long-term stable operation of the conveyor.

[0044] Furthermore, rollers 6 are provided between the reversing device 12 and the corresponding first roller 7 and second roller 10. The main function of the rollers 6 is to support and guide the transmission belt 4 and the traction wire rope 3, reduce the direct contact between them and the rollers, and thus reduce wear and friction resistance. The provision of rollers 6 helps to improve the running stability and efficiency of the conveyor.

[0045] Furthermore, a tensioning device 9 is provided between the reversing device 12 at the first roller 7 and the first roller 7. The main function of the tensioning device 9 is to adjust the tension of the transmission belt 4 to ensure that it maintains appropriate tension during operation. Appropriate tension helps prevent the transmission belt 4 from slackening or overstretching, thereby maintaining its stable operation and extending its service life.

[0046] 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.
