[0033] 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.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a portable support device for replacing conveyor roller frames, including a base 1. A limiting plate 9 is fixedly connected to the top of the base 1, and a fixing block 10 is fixedly connected to the top of the base 1. The base 1 provides support for the limiting plate 9 and the fixing block 10, enabling them to operate stably. A connecting plate 11 is rotatably connected to the outer periphery of both ends of the fixing block 10. A push plate 12 is rotatably connected to the middle of the other end of the connecting plate 11. The fixing block 10 provides support for the connecting plate 11, enabling it to support the push plate 12, thus allowing the push plate 12 to operate stably. A bidirectional threaded rod 13 is threadedly connected to the middle of the push plate 12, and a connecting plate 2 14 is rotatably connected to the outer periphery of the other end of the push plate 12. The push plate 12 provides support for the bidirectional threaded rod 13, enabling it to operate stably. Rotating the bidirectional threaded rod 13 allows the push plate 12 to move, thereby driving the connecting plate 11 to move.

[0035] A fixing block 15 is rotatably connected to the middle of the other end of the connecting plate 14. A base plate 16 is fixedly connected to the top of the fixing block 15. The push plate 12 provides support for the connecting plate 14, enabling it to work stably and move. This causes the connecting plate 14 to move the fixing block 15, which in turn moves the base plate 16, thus supporting the belt conveyor's sleeve and making the replacement of the idler rollers more convenient. A telescopic mechanism is installed in the middle of the base 1. The telescopic mechanism allows the length of the base 1 to be adjusted in time according to the width of the belt conveyor, so that the idler roller replacement device can be stably placed on the frame of the belt conveyor. The telescopic mechanism includes an extension component, an auxiliary component, and a positioning component. The extension component includes a telescopic rod 2, which is slidably connected to the middle of the base 1. A baffle 4 is fixedly connected to the end of the telescopic rod 2. The auxiliary component includes an auxiliary slider 3, which is fixedly connected to the outside of the telescopic rod 2. The baffle 4 provides a limiting effect for the base 1, making the base 1 stable. The telescopic rod 2 is fixedly mounted on the frame of the belt conveyor. An auxiliary slider 3 provides auxiliary limiting for the telescopic rod 2, ensuring a more stable fixation during movement and support. This allows for better support of the idler roller changing device. A positioning hole 5 is provided on the outer side of the telescopic rod 2. The positioning assembly includes a positioning block 7, which is fixedly connected to the outer side of the base 1. A positioning rod 6 is slidably connected to the center of the positioning block 7. The positioning rod 6 and the positioning hole 5 are interlocked. A spring 8 is installed inside the positioning block 7, providing support for the positioning rod 6 for stable operation. The positioning hole 5 and the positioning rod 6 work together to lock the telescopic rod 2, preventing displacement during operation. The spring 8 provides a reset function for the positioning rod 6, allowing it to return to its original position after movement. Through the cooperation of the various structures in the telescopic mechanism, the length of the base 1 can be adjusted in a timely manner according to the width of the belt conveyor, enabling the idler roller changing device to adapt to belt conveyors of different widths and making idler roller replacement more convenient.

[0036] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5A support plate 17 is rotatably connected to the middle of the base plate 16. A rotating shaft 23 is fixedly connected to the middle of the other end of the support plate 17. A fixed plate 18 is rotatably connected to the outer periphery of the rotating shaft 23. The fixed plate 18 and the support plate 17 are connected by the rotating shaft 23 to form a whole, thereby enabling better operation. A sliding groove 19 is provided on the top of the fixed plate 18. A limit rod 20 is slidably connected to the middle of the fixed plate 18. The limit rod 20 can move inside the fixed plate 18 through the sliding groove 19. A spring 22 is provided inside the fixed plate 18. A limit hole 21 is provided on the inner wall of the base plate 16. The limit rod 20 and the limit hole 21 are engaged with each other. The cooperation of the limit rod 20 and the limit hole 21 enables the fixed plate 18 to be adjusted. The system is locked to prevent displacement during operation and ensures stable operation. Spring 22 allows the limit rod 20 to move and then reset. A connecting post 24 is installed in the middle of the support plate 17, with a connecting block 25 fixedly connected to the bottom of the connecting post 24. A compression spring 26 is sleeved around the outer periphery of the connecting post 24, and an auxiliary plate 27 is fixedly connected to the top of the connecting post 24. The cooperation of the connecting post 24, connecting block 25, and compression spring 26 allows the auxiliary plate 27 to reset. A socket 29 is provided at the top of the support plate 17, and a pin 28 is fixedly connected to the bottom of the auxiliary plate 27. The cooperation of the pin 28 and the socket 29 fixes the auxiliary plate 27, preventing displacement during operation.

[0037] Working principle: When adjusting the length of the base 1, the positioning rod 6 can be pulled to disengage it from the positioning hole 5, thus releasing the lock on the telescopic rod 2. At this time, the baffle 4 can be pulled to move the telescopic rod 2. When the base 1 is adjusted to the appropriate length, the positioning rod 6 is released and the spring 8 pushes it to reset, thereby engaging with the positioning hole 5 and locking the telescopic rod 2, thus fixing the adjusted length.

[0038] By rotating the bidirectional threaded rod 13, the push plate 12 is moved, which in turn moves the connecting plate 11, causing it to rotate along the fixed block 10. At the same time, the push plate 12 moves the connecting plate 14, causing it to rotate along the fixed block 15 and move the fixed block 15. The fixed block 15 then moves the base plate 16, thereby supporting the belt of the conveyor belt.

[0039] When the support area of ​​the belt is increased, the limiting rod 20 can be moved by pushing it, thereby disengaging it from the limiting hole 21 and releasing the lock on the fixing plate 18. At this time, the support plate 17 can be pulled to rotate along the base plate 16, thereby moving the fixing plate 18. When it reaches the designated position, the spring 22 pushes the limiting rod 20 to move, locking it with the limiting hole 21, thereby locking the fixing plate 18 and the support plate 17. At this time, the auxiliary plate 27 is pulled, moving the connecting column 24 and the connecting block 25. The movement causes the compression spring 26 to extend and deform, while the auxiliary plate 27 drives the pin 28 to move, thus disengaging it from the insertion hole 29. At this time, the auxiliary plate 27 can be rotated. When rotated to the designated position, the compression spring 26 pushes the connecting block 25 to move, the connecting block 25 drives the connecting column 24 to move, the connecting column 24 drives the auxiliary plate 27 to move, and the auxiliary plate 27 drives the pin 28 to engage with the insertion hole 29, thereby fixing the position of the auxiliary plate 27, thereby increasing the support area of ​​the belt, and making the replacement of the idler roller more convenient.

[0040] 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.
