Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, and in particular to a telescopic belt conveyor that can be flexibly adjusted. Background Technology

[0002] In modern industrial production and logistics transportation, belt conveyors, as core equipment for material conveying, are widely used in various scenarios such as mining, warehousing and logistics, and port transportation. Their ability to flexibly adjust the conveying distance according to the actual usage scenario, as well as to maintain stable tension and reliability during operation, directly affects production efficiency and equipment lifespan.

[0003] Existing belt conveyors have significant shortcomings in practical applications. Traditional belt conveyors mostly employ a fixed-length design, which often fails to quickly and flexibly adjust the belt length to meet varying transportation needs, such as adjusting the conveying distance in different work sites or changing the conveying path due to production process variations. Furthermore, during belt conveyor operation, existing tensioning and support structures cannot achieve dynamic and coordinated adjustment. The tensioning device struggles to adjust the tension in real time according to changes in belt length, and the support structure cannot provide stable support for the belt. This makes the belt prone to slackness, slippage, and even deviation or deformation during transportation, reducing the belt conveyor's operating efficiency, increasing the equipment failure rate, and shortening its service life. To address these technical problems, this application proposes a flexibly adjustable telescopic belt conveyor. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flexible, adjustable telescopic belt conveyor. This conveyor utilizes a hydraulic rod to control the sliding of a trolley within a guide rail, and a motor-driven double-ended threaded rod to adjust the slider position, enabling flexible extension and retraction of the transmission belt length. This allows for rapid adjustment of the conveying distance to adapt to different transportation needs, improving versatility and flexibility. Simultaneously, the tension roller and support roller work together to ensure the belt maintains appropriate tension and stability during extension and retraction, preventing slackness, slippage, and misalignment, significantly improving operating efficiency, reducing failure rates, and extending equipment lifespan.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A flexible adjustable telescopic belt conveyor includes a base. Two trolleys are arranged on the top side of the base. One end of each trolley is connected to the middle of the base via a telescopic assembly for controlling the movement of the trolley. A drive roller is rotatably connected to the other end of each trolley. A slide rail is fixedly connected to the middle of the bottom side of the trolley. Two sliders are slidably connected to the bottom side of the slide rail. The two sliders are connected to each other via a moving assembly. A connecting rod is rotatably connected to the bottom side of each slider. A support frame is rotatably connected to the bottom end of the connecting rod. A tension roller is rotatably connected to the inner wall of the support frame. A transmission belt is arranged between the two drive rollers.

[0007] Furthermore, the telescopic assembly includes a fixing block fixedly connected to the middle of the top side of the base, and a hydraulic rod is provided on the outer wall of the fixing block. The driving end of the hydraulic rod is fixedly connected to one end of the trolley.

[0008] Furthermore, the moving component includes a double-threaded rod rotatably connected to the bottom side of the slide rail, the slider being threadedly connected to the outer wall of the double-threaded rod, and a second motor being mounted on the bottom side of the trolley via a fixing bracket, the drive end of the second motor being fixedly connected to the outer wall of the double-threaded rod.

[0009] Furthermore, a telescopic rod is fixedly connected to the bottom side of the trolley, and the bottom end of the telescopic rod is fixedly connected to the top side of the support frame.

[0010] Furthermore, a support roller is rotatably connected to the top side of the trolley, and the support roller is disposed on the inner wall of the top side of the transmission belt.

[0011] Furthermore, the bottom outer wall of the tension roller is disposed on the bottom inner wall of the transmission belt to control the tension of the transmission belt.

[0012] Furthermore, a motor is mounted on the outer wall of the other end of the trolley via a fixing frame, and the driving end of the motor is fixedly connected to the outer wall of the drive roller.

[0013] Furthermore, a guide rail is fixedly connected to the top side of the base, and the bottom side of the trolley is located inside the guide rail.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the belt conveyor controls the sliding of the trolley within the base guide rail via a hydraulic rod, and adjusts the position of the slider by driving a double-headed threaded rod with a motor, thus achieving flexible extension and retraction of the transmission belt length. This allows the belt conveyor to quickly adjust the conveying distance according to actual usage scenarios, adapting to different transportation needs and improving the versatility and flexibility of the equipment.

[0016] 2. In this invention, the coordinated action of the tension roller and the support roller ensures that the transmission belt maintains appropriate tension and stability throughout the extension and retraction process. The tension roller dynamically adjusts the belt tension to prevent slackness or slippage, while the support roller provides stable support for the belt, preventing it from shifting or deforming during transport. This significantly improves the operating efficiency of the belt conveyor, reduces the failure rate, and extends the service life of the equipment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3This utility model provides an embodiment of a flexible adjustable telescopic belt conveyor, comprising a base 1, two trolleys 2 on the top side of the base 1, a fixed block 6 fixedly connected to the middle of the top side of the base 1, a hydraulic rod 7 on the outer wall of the fixed block 6, the driving end of the hydraulic rod 7 fixedly connected to one end of the trolley 2 for controlling the movement of the trolley 2, a drive roller 4 rotatably connected to the other end of the trolley 2, a slide rail 8 fixedly connected to the middle of the bottom side of the trolley 2, two sliders 9 slidably connected to the bottom side of the slide rail 8, a double-ended threaded rod 10 rotatably connected to the bottom side of the slide rail 8, the sliders 9 threadedly connected to the outer wall of the double-ended threaded rod 10, a second motor 11 mounted on the bottom side of the trolley 2 via a fixed frame, the driving end of the second motor 11 fixedly connected to the outer wall of the double-ended threaded rod 10, a connecting rod 12 rotatably connected to the bottom side of the sliders 9, a support frame 13 rotatably connected to the bottom end of the connecting rod 12, a tension roller 14 rotatably connected to the inner wall of the support frame 13, and a transmission belt 16 between the two drive rollers 4;

[0024] Specifically, in actual use, to meet different usage needs, the hydraulic rod 7 can be activated to control the trolley 2 to slide within the guide rail at the top of the base 1. When the trolley 2 moves, the distance between the two drive rollers 4 located on it will decrease accordingly. Subsequently, the motor 11 is activated to drive the double-headed threaded rod 10 to rotate, thereby controlling the two sliders 9 to slide on the outer wall of the slide rail 8, so that the distance between the two sliders 9 can be brought closer or farther. By rotating the connecting rod 12 between the support frame 13 and the sliders 9, the height of the support frame 13 and the tension roller 14 can be changed, ensuring that the bottom side of the tension roller 14 is always tightly attached to the bottom inner wall of the transmission belt 16. In this way, when the distance between the two trolleys 2 is shortened, the transmission belt 16 can always maintain an appropriate tension between the two drive rollers 4, thereby realizing the flexible extension and retraction adjustment of the belt conveyor. During use, the support roller 3 provides support for the transmission belt 16, and at the same time, the rotating support roller 3 at one end of the trolley 2 can also guide the transmission belt 16. When the motor 5 is started, the drive roller 4 rotates, which in turn controls the sliding of the transmission belt 16, thereby realizing the conveyor function of the belt conveyor.

[0025] Reference Figures 1-3 A telescopic rod 15 is fixedly connected to the bottom side of the trolley 2. The bottom end of the telescopic rod 15 is fixedly connected to the top side of the support frame 13. A support roller 3 is rotatably connected to the top side of the trolley 2. The support roller 3 is set on the inner wall of the top side of the transmission belt 16. The outer wall of the bottom side of the tension roller 14 is set on the inner wall of the bottom side of the transmission belt 16 to control the tension of the transmission belt 16. A motor 5 is installed on the outer wall of the other end of the trolley 2 through a fixed frame. The drive end of the motor 5 is fixedly connected to the outer wall of the drive roller 4. A guide rail is fixedly connected to the top side of the base 1. The bottom side of the trolley 2 is set inside the guide rail.

[0026] Specifically, the tension of the transmission belt 16 and the telescopic function of the belt conveyor are controlled by the sliding of the trolley 2 within the guide rail, in conjunction with the extension and retraction of the telescopic rod 15 and the position adjustment of the tension roller 14. Simultaneously, the support roller 3 provides stable support for the transmission belt 16, ensuring it remains flat during transport. The motor 5 drives the drive roller 4 to rotate, further enabling the sliding of the transmission belt 16 and completing the material transport task. This allows for flexible adjustment of the belt conveyor length to adapt to different working scenarios and transport requirements. Furthermore, the synergistic effect of the tension roller 14 and the support roller 3 ensures that the transmission belt 16 maintains appropriate tension and stability at all times, improving the belt conveyor's operating efficiency and reliability, reducing the failure rate, and extending the equipment's service life.

[0027] Working principle: In actual use, when the device needs to be extended or retracted to meet usage requirements, the hydraulic rod 7 can be activated to control the sliding of the trolley 2 within the guide rail on the top side of the base 1. At this time, the distance between the two drive rollers 4 located on the trolley 2 is brought closer. Then, the double-headed threaded rod 10 is rotated by starting the motor 11, which controls the sliding of the two sliders 9 on the outer wall of the slide rail 8, thus bringing the distance between the two sliders 9 closer or farther. The rotation of the connecting rod 12 between the support frame 13 and the sliders 9 will drive the height of the support frame 13 and the tension roller 14 to be adjusted. The bottom side of the tension roller 14 is always in contact with the inner wall of the bottom side of the transmission belt 16, ensuring that the transmission belt 16 maintains sufficient tension between the two drive rollers 4 when the distance between the two carriages 2 is shortened, thereby realizing the flexible extension and retraction adjustment of the belt conveyor. In actual use, the support roller 3 provides support for the use of the transmission belt 16. At the same time, the support roller 3 rotating at one end of the carriage 2 guides the transmission belt 16. Starting the motor 5 drives the drive roller 4 to rotate, which controls the sliding of the transmission belt 16 to achieve the conveying effect of the belt conveyor.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
