[0025] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0026] This utility model provides a belt conveyor drive device for belt conveyors, which is beneficial to improving transmission efficiency, reducing transmission loss, having a reliable structure, and being convenient for later assembly, disassembly and maintenance.
[0027] Please combine Figure 1The belt conveyor drive unit includes a permanent magnet motor 1, a coupling 2, a drive drum 5, a head frame 6, and a backstop 8. The permanent magnet motor 1 is connected to the coupling 2, the coupling 2 is connected to the drive drum 5, and the drive drum 5 is connected to the backstop 8. The permanent magnet motor 1, coupling 2, drive drum 5, and backstop 8 are all located on the same axis. The drive drum 5 is rotatably mounted on the head frame 6. In this belt conveyor drive unit, the permanent magnet motor 1 is connected to the drive drum 5 through the coupling 2, resulting in high transmission efficiency, reduced power loss, and improved assembly and disassembly efficiency and convenience. Since the belt conveyor is inclined upwards, there is a tendency for it to reverse direction when stopped; the backstop 8 prevents this reverse slippage and reduces safety hazards.
[0028] Optionally, a limiting plate 9 is also included, which limits the backstop 8. The limiting plate 9 can be fixed to the frame or any carrier. The limiting plate 9 is connected to the outer ring of the backstop 8. It can be understood that the backstop 8 includes an outer ring, an inner ring, and a locking element. The locking element includes, but is not limited to, a wedge or a spring. The inner ring is rigidly connected to the roller shaft of the drive roller 5, and the inner ring will rotate synchronously with the drive roller 5. The outer ring is a fixed end, used to connect with the limiting plate 9 to achieve reverse limiting. Its anti-reverse and limiting principle is roughly as follows: When the drive roller 5 is operating normally, if it rotates in the forward direction, the inner ring drives the locking element to rotate with it. At this time, the locking element, such as the wedge, is not locked between the inner and outer rings, and the backstop 8 does not interfere with power transmission, only rotating freely or remaining stationary with the inner ring. When the drive roller 5 attempts to reverse due to load (such as material gravity or inertia), the inner ring rotates in the opposite direction, and the locking element, such as the wedge, is instantly locked between the inner and outer rings under friction or spring action, forming a rigid lock. Because the limiting plate 9 fixes the outer ring, it can prevent the inner ring from continuing to reverse, thereby preventing the drive roller 5 and the conveyed material from slipping backward. In this way, the backstop 8 can prevent slippage and reduce safety hazards.
[0029] Optionally, the coupling 2 is equipped with a protective cover 3. The protective cover 3 can prevent foreign objects from falling into the coupling 2, improve the reliability of the coupling 2 operation, reduce the risk of failure, and help extend the service life of the coupling 2.
[0030] Optionally, coupling 2 can be a serpentine spring coupling 2 or a hydraulic coupling 2. In this embodiment, coupling 2 is a serpentine spring coupling 2. Serpentine spring coupling 2 has good elastic buffering effect; the serpentine spring can absorb impact, reduce vibration, and protect the motor and drive drum 5. It can also allow for certain installation deviations (such as radial, angular, and axial deviations), reducing the equipment installation accuracy requirements. In addition, serpentine spring coupling 2 has a simple structure, small size, light weight, low manufacturing cost, and is convenient for disassembly and maintenance.
[0031] Optionally, the drive roller 5 can be ceramic-coated to improve its wear resistance and reduce maintenance workload. Of course, in some embodiments, the drive roller 5 can also be rubber-coated; this is not specifically limited here.
[0032] Optionally, the drive roller 5 has a roller shaft, on which a speed sensor 10 is mounted. The speed sensor 10 can detect the rotational speed of the drive roller 5 in real time, and adjust the rotational speed of the drive roller 5 by adjusting the speed of the permanent magnet motor 1 through the controller. By detecting the rotational speed of the drive roller 5, it is possible not only to determine whether the drive roller 5 is slipping, but also to intelligently adjust the drive speed, thereby realizing intelligent adjustment of the conveyor's conveying capacity, improving transmission efficiency, and reducing energy consumption.
[0033] It should be noted that the speed sensor 10 can have various structural forms, such as Hall effect, capacitive, magnetoelectric or photoelectric speed sensors 10, as long as they can detect the rotational speed of the transmission roller 5 in real time, no specific limitation is made here.
[0034] Optionally, the roller shaft is connected to the head frame 6 via bearings 7. In this embodiment, the roller shafts at both ends of the drive roller 5 are connected to the head frame 6 via bearings 7, ensuring balanced force and smooth rotation. The head frame 6 provides support and load-bearing for the drive roller 5. The radial runout of the drive roller 5 during operation meets industry standard requirements.
[0035] Optionally, the permanent magnet motor 1 is provided with a mounting base 4. The mounting base 4 is used to support and fix the permanent magnet motor 1. It should be understood that the permanent magnet motor 1 is driven to one or both ends of the transmission drum 5. That is, the permanent magnet motor 1 can be installed on the left side of the transmission drum 5, such as... Figure 1 As shown. Alternatively, in some embodiments, the permanent magnet motor 1 may also be installed on the right side of the transmission drum 5, or the permanent magnet motor 1 may be installed on both sides of the transmission drum 5 to provide more sufficient power, which is not specifically limited here.
[0036] This utility model provides a belt conveyor, including a belt conveyor drive device as described in any of the foregoing embodiments. A belt is fitted onto a drive drum 5 to realize material conveying or power transmission. In this embodiment, the permanent magnet motor 1 is of high power; for example, a permanent magnet motor 1 with a power greater than or equal to 315kW can be used in a wide-width belt conveyor. Wide-width belt conveyors have large conveying capacities and require relatively large driving power.
[0037] The belt conveyor drive device and belt conveyor provided in this embodiment of the utility model have the following beneficial effects, including: In this belt conveyor drive unit, the permanent magnet motor 1 is connected to the drive drum 5 via a coupling 2, eliminating the need for transmission components such as a reducer. This results in high transmission efficiency, reduced power loss, and improved assembly and disassembly efficiency and convenience. A backstop 8 is included to prevent slippage during upward tilting transport, reducing safety hazards. The structure is relatively simple, with high assembly and disassembly efficiency and easier maintenance. A speed sensor 10 monitors the rotational speed of the drive drum 5 in real time, and the speed of the drive drum 5 is adjusted by regulating the speed of the permanent magnet motor 1 via a controller. Monitoring the rotational speed of the drive drum 5 not only determines whether it is slipping but also allows for intelligent adjustment of the drive speed, enabling intelligent regulation of the belt conveyor's conveying capacity, improving transmission efficiency, and reducing energy consumption. Furthermore, this belt conveyor drive unit is quick to assemble and disassemble, has a compact structure, and occupies little space.
[0038] The belt conveyor provided in this embodiment of the utility model includes the belt conveyor drive device described above, which has a simple structure, high transmission efficiency, and is safe and reliable.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Any modifications, equivalent substitutions, improvements, etc., should be included within the protection scope of this utility model.
