Description

Technical Field

[0001] The invention belongs to the technical field of bulk material transportation and relates to a steel cable belt conveyor. Background Art

[0002] A steel cable belt conveyor uses a steel wire rope as the traction element and a conveyor belt as the load-bearing element. Steel cable belt conveyors offer advantages such as long conveyor distances, long belt life, and low power consumption. Steel cable belt conveyors are commonly used for material transportation and are widely used in mining, ports, metallurgy, chemical engineering, and other fields.

[0003] In existing technology, steel cable belt conveyors utilize steel wire rope tracks on both sides of the conveyor belt, leveraging the high strength and toughness of the steel wire rope to effectively improve the conveyor's load-bearing capacity and operational stability.

The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and the following embodiments and features in the embodiments can be combined with each other without conflict.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, the terms describing the positional 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 Figures 1 to 4, which is a steel cable belt conveyor provided by the present invention. A first roller 7 and a second roller 10 are respectively provided 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, and two annular traction steel 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; a plurality of belt trolleys 5 are arranged at intervals on the traction steel rope 3 and move synchronously with it, and each belt trolley 5 is provided with a supporting groove 19 for limiting the shape of the transmission belt 4; a reversing device 12 for changing the carrying relationship between the belt trolley 5 and the traction steel rope 3 is provided at the first roller 7 and the second roller 10. The reversing device 12 makes the belt trolley 5 upright or upside down on the traction steel rope 3 so that the supporting groove 19 of the belt trolley 5 always faces the transmission belt 4.

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

[0034] Furthermore, multiple tape trolleys 5 are mounted on the traction wire rope 3 at equal intervals along its length. The trolleys 5 synchronize their movement with the traction wire rope 3 via the annular grooves on the guide wheels 16, ensuring the smooth movement of the transmission belt 4 during transport. Each trolley 5 is equipped with a support groove 19, into which the transmission belt 4 rests. These grooves constrain the shape of the transmission belt 4, preventing deformation or displacement during operation. This design not only improves transport efficiency but also significantly extends the service life of the transmission belt 4.

[0035] Furthermore, a support trough 19 is provided on the base frame 20 of the tape trolley 5, and at least one clamping arm group is provided on two sides of the base frame 20 parallel to the conveying tape 4. Each clamping arm group includes two opposing clamping arms 13, each of which is hinged to the base frame 20, with its free end pivoting about a corresponding hinge point driven by its own weight. When the tape trolley 5 is positioned on the traction wire rope 3, the clamping arms 13 rotate away from the conveying tape 4 due to gravity, and the two clamping arms 13 are in an open position, allowing the conveying tape 4 to be stably placed in the support trough 19, ensuring stability and reliability during conveying. When the tape trolley 5 is suspended upside down on the traction wire rope 3, the clamping arms 13 rotate toward the conveying tape 4 due to gravity, and the two clamping arms 13 are in a closed position, allowing the conveying tape 4 to rest on the two clamping arms 13, preventing the conveying tape 4 from falling off when suspended upside down, 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 reduces manufacturing and maintenance costs.

[0036] Furthermore, 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 to the base frame 20 of the belt trolley 5. The annular groove on the guide wheel 16 closely mates with the traction wire rope 3, achieving seamless connection and synchronous movement between the two through physical engagement. This design not only simplifies the connection structure between the belt trolley 5 and the traction wire rope 3, but also greatly improves the operating 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 conjunction 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 provides a reversing device 12 at the first roller 7 and the second roller 10. The reversing device 12 can adjust the loading 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 a first spiral roller 15 is provided on both end faces thereof, and a spiral groove for winding the traction wire rope 3 is provided on the first spiral roller 15; after the traction wire rope 3 is wound on the first spiral roller 15, it is respectively wound to the corresponding first roller 7 or the second roller 10, 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 is provided at the bottom of the tape trolley 5 to cooperate with the reversing ring groove 18. The depth of the reversing ring groove 18 is less than the height of the reversing slider 17 to ensure that the reversing device 12 can lift the tape trolley 5. Specifically, when the tape trolley 5 moves above the reversing device 12, the reversing slider 17 engages with the reversing annular groove 18 to lift the tape trolley 5, allowing the traction wire rope 3 to disengage from the guide wheel 16, and the tape trolley 5 to rotate synchronously with the reversing device 12. When the tape trolley 5 rotates below the reversing device 12, the reversing slider 17 disengages from the reversing annular groove 18, and the tape trolley 5 falls toward the traction wire rope 3, causing the traction wire rope 3 to engage with the guide wheel 16, and the tape trolley 5 to move synchronously with the traction wire rope 3. This design ensures that the support groove 19 always faces the transmission belt 4, maintaining effective support and shape restriction for 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 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, second convoluted rollers 21 are also installed on either side of the first drum 7. These second convoluted rollers 21 are equipped with spiral grooves for winding the traction wire rope 3. The second convoluted rollers 21 are mounted on either side of the first drum 7, forming an integrated structure with the drum body. The surfaces of the second convoluted rollers 21 are machined with spiral grooves, allowing the traction wire rope 3 to be wound around them. When the first drum 7 rotates under the drive mechanism, the second convoluted rollers 21 rotate synchronously, driving the traction wire rope 3 and the transmission belt 4 to move continuously and smoothly. This structural design not only achieves efficient power transmission, namely, the rotational kinetic energy is directly transferred from the drum to the traction wire rope 3 and the transmission belt 4, reducing energy loss and improving transmission efficiency. Furthermore, the tight fit between the second convoluted rollers 21 and the traction wire rope 3 enhances the overall stability of the cable belt conveyor, effectively preventing the traction wire rope 3 from slipping or deflecting during transmission. Furthermore, the provision of the second convoluted rollers 21 facilitates maintenance and adjustment of the 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 acts directly 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 effect on the traction wire rope 3 and ensure the long-term stable operation of the conveyor.

[0044] Furthermore, idlers 6 are installed between the reversing device 12 and its corresponding first roller 7 and second roller 10. The primary function of the idlers 6 is to support and guide the conveyor belt 4 and traction wire rope 3, reducing direct contact between them and the rollers, thereby reducing wear and frictional resistance. The installation of idlers 6 helps improve the smoothness and efficiency of the conveyor's operation.

[0045] Furthermore, a tensioning device 9 is provided between the reversing device 12 and the first roller 7. The tensioning device 9 primarily adjusts the tension of the transmission belt 4, ensuring proper tension during operation. Proper tension helps prevent the transmission belt 4 from slacking or overstretching, thereby maintaining stable operation and extending its service life.

[0046] 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.
