Technical Field

[0001] This utility model belongs to the field of conveyor belt lifting technology, specifically a double-arm conveyor belt lifting robot. Background Technology

[0002] In modern industrial production, conveyor belts, as efficient and continuous material transport equipment, are widely used in many fields, such as manufacturing, logistics and warehousing, food processing, and mining. They enable large-scale, long-distance material transport, greatly improving production efficiency and reducing labor costs. However, when conveyors are used for extended periods, the idler rollers need to be replaced, thus requiring the conveyor belt to be supported.

[0003] However, most existing conveyor belt lifting methods rely on manual labor, resulting in low lifting efficiency. Furthermore, existing lifting devices can only be used with supports of the same width, limiting their application range. To address these issues, this invention designs a dual-arm conveyor belt lifting robot. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a dual-arm conveyor belt lifting robot, which effectively solves the problems mentioned in the background art.

A main roller is provided at the top of each roller bracket, and side rollers are provided at the left and right ends of the main roller. Each conveyor frame has a bracket at its top, with a connecting strip fixed to the inner side of the left bracket and a positioning rod fixed to the inner side of the right bracket. Two movable shafts are fixed to the left side of the positioning rod, with the left end of each movable shaft slidably connected to the connecting strip. A movable rod is fixed to the inner side of each bracket, and a lifting rod is fixed to the inner side of each movable rod.

A movable frame is fixed to the inner side of each adapter plate and each positioning plate, and a movable wheel is rotatably connected inside each movable frame.

[0006] Preferably, each conveyor frame has a support rod fixed at its bottom, a controller fixed on the left side of the left end of the bracket, a power supply fixed on the top of the controller, a main idler bracket fixed on the top of the idler bracket, the main idler bracket and the main idler inside the main idler bracket are rotatably connected by a rotating shaft, side idler brackets are fixed at both ends of the main idler bracket, each side idler bracket and the side idler inside the side idler bracket are rotatably connected by a rotating shaft, and a conveyor belt is frictionally connected to the top of the main idler.

[0007] Preferably, each bracket has a support plate fixed at its lower end, a stabilizing wheel rotatably connected inside each support plate, each stabilizing wheel being in close contact with the conveyor frame at its bottom, the bottom of each bracket being fixedly connected to the moving frame, a moving wheel motor rotatably connected inside each moving wheel at its front end, each moving wheel motor being fixedly connected to the moving frame at its outer side, and an adapter rod fixed at the top of each positioning plate, each adapter rod being fixedly connected to the adapter plate at its top.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention connects to a motor that drives the main connecting gear to rotate, which in turn drives the front connecting auxiliary gear to rotate, which in turn drives the chain to rotate, which in turn drives the rear connecting auxiliary gear to rotate, which in turn drives the two connecting nuts to rotate, which in turn drives the two moving shafts to move.

This allows for the clamping of conveyor belts of varying thicknesses, expanding the overall applicability of the device and ensuring effective clamping, lifting, and accurate lifting.

[0013] This invention uses a positioning plate to position the bottom moving frame. The device uses stabilizing wheels to ensure the stability of the support. At the same time, the moving wheel motor can drive the moving wheel to rotate, so that the entire device can move along the conveyor frame, thereby improving the degree of automation. In addition, the device uses an adapter rod to change the distance between the adapter plate and the positioning plate, thereby adapting to conveyor frames of different thicknesses, thus further improving the application range of the entire device.

[0028] When using this device, the operator places the bracket 2 on both sides of the conveyor frame 1. Then, the operator places one of the positioning plates 305 and the adapter plate 307 at the outer end of the conveyor frame 1. The controller 201 then controls the adapter rod 306 at this end to retract, causing the positioning plate 305 to move closer to the adapter plate 307. This makes the moving wheel 303 at this end fit tightly against the conveyor frame 1. Furthermore, the controller 201 controls the connecting motor 507 to operate, thereby driving the connecting main gear 506 to rotate, which in turn drives the front connecting secondary gear 504. The rotation of the chain 505 causes the rear connecting gear 504 to rotate, which in turn causes the two moving shafts 501 to move. This causes the positioning rod 5 to move to the left, bringing the right-end bracket 2 closer to the right-end conveyor frame 1. When the right-end positioning plate 305 and the right-end adapter plate 307 are close to the right-end conveyor frame 1, the controller 201 controls the right-end adapter rod 306 to make the right-end moving wheel 303 press tightly against the conveyor frame 1, thereby increasing the usability of the entire device. At this time, the stabilizing wheel 301 prevents the bracket 2 from... The support 2 is tilted to ensure its stability. At this time, the controller 201 controls the two moving wheel motors 304 to operate, thereby driving the moving wheels 303 to rotate. This allows the support 2 to move along the conveyor frame 1, ensuring accurate lifting. When it moves to the desired conveyor belt lifting position, the controller 201 controls the moving rod 6 to extend or retract, thereby driving the lifting rod 601 to extend or retract, which in turn drives the clamping rod 603 to move. Furthermore, the extension or retraction of the clamping rod 603 drives the 604 to move. At this time, the controller 201 can... The lifting camera 602 monitors the lifting situation. Furthermore, the controller 201 controls the track 704 to rotate the positioning block 703, ensuring lifting accuracy. The controller 201 also controls the clamping rod 702 to move the main clamping plate 7 along the track 704, changing the distance between the main clamping plate 7 and the auxiliary clamping plate 701 to accommodate conveyor belts 401 of different thicknesses, thus clamping the conveyor belt 401. Finally, the controller 201 controls the lifting rod 601 to operate again, thereby lifting the conveyor belt 401.

[0029] The working process of this utility model is as follows: When using this device, the operator places the bracket 2 on both sides of the conveyor frame 1. At this time, the operator places one of the positioning plates 305 and the adapter plate 307 on the outer end of the conveyor frame 1. Then, the controller 201 controls the adapter rod 306 at this end to retract, so that the positioning plate 305 moves closer to the adapter plate 307, thereby making the moving wheel 303 at this end fit tightly against the conveyor frame 1. Further, the controller 201 controls the connecting motor 507 to work, thereby driving the connecting main gear 506 to rotate, thereby driving the front end... The connecting gear 504 rotates, thereby driving the chain 505 to rotate, which in turn drives the rear connecting gear 504 to rotate, thereby driving the two moving shafts 501 to move. This causes the positioning rod 5 to move to the left, bringing the right-end bracket 2 closer to the right-end conveyor frame 1. When the right-end positioning plate 305 and the right-end adapter plate 307 are close to the right-end conveyor frame 1, the controller 201 controls the right-end adapter rod 306 to make the right-end moving wheel 303 press tightly against the conveyor frame 1, thereby increasing the usability of the entire device. At this time, the stabilizing wheel 301 can prevent... To prevent the support 2 from tipping over and ensure its stability, the controller 201 controls the two moving wheel motors 304 to operate, thereby driving the moving wheels 303 to rotate. This allows the support 2 to move along the conveyor frame 1, ensuring accurate lifting. When the support reaches the desired conveyor belt lifting position, the controller 201 controls the moving rod 6 to extend or retract, thereby driving the lifting rod 601 to extend or retract, which in turn drives the clamping rod 603 to move. Furthermore, the extension or retraction of the clamping rod 603 drives the 604 to move. At this point, the controller 201 can... The lifting camera 602 monitors the lifting situation. The controller 201 further controls the track 704 to rotate the positioning block 703, ensuring lifting accuracy. The controller 201 then controls the clamping rod 702 to move the main clamping plate 7 along the track 704, changing the distance between the main clamping plate 7 and the auxiliary clamping plate 701 to accommodate conveyor belts 401 of different thicknesses, thus clamping the conveyor belt 401. Finally, the controller 201 controls the lifting rod 601 to operate again, thereby lifting the conveyor belt 401.
