[0024] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0025] like Figure 1 As shown, this specific embodiment provides a conveyor belt roller replacement tool, including a supporting rod 1 and two lifting assemblies. The lifting assemblies are detachably provided at both ends of the supporting rod 1. The lifting assemblies include a lifting rod 2 and a lifting mechanism. The lifting rod 2 is detachably connected to the supporting rod 1. The lifting mechanism includes a protective shell 3. A driving assembly is provided in the protective shell 3. The driving assembly can drive the lifting rod 2 to move upward. The lifting mechanism also includes a hook 4. The hook 4 is provided on the protective shell 3 and can be hung on the conveyor belt guardrail.

[0026] This specific embodiment achieves the raising of the conveyor belt by pulling up to lift the conveyor belt. The supporting rod 1 only needs to establish a connection with the lifting rod 2. Compared with the existing technology, there is no need to wait for the supporting rod 1 to extend, which saves the time of adjusting the length of the supporting rod 1, significantly shortens the time of lifting the conveyor belt, and improves the efficiency of replacing rollers.

[0027] like Figure 1 As shown, in order to achieve a quick connection between the supporting rod 1 and the lifting rod 2, in this specific embodiment, a lifting ring 12 is provided at the lower end of the lifting rod 2, and the supporting rod 1 can pass through the lifting ring 12. The supporting rod 1 can establish a connection with the lifting rod 2 by passing through the two lifting rings 12. When the lifting rod 2 moves upward, the supporting rod 1 can be pulled to drive the conveyor belt to lift; in order to prevent the supporting rod 1 from slipping off the lifting ring 12 after the bow deformation under the action of the conveyor belt, anti-slip caps 103 are provided at both ends of the supporting rod 1, and the anti-slip caps 103 can abut against the lifting ring 12.

[0028] like Figure 2 and Figure 3As shown, in order to achieve the driving and reliable position locking of the lifting rod 2, in this specific embodiment, the driving assembly can adopt the following structure: the driving assembly includes a transmission gear 5, a driving ratchet 6 and a driving shaft 7. The transmission gear 5 is rotatably arranged in the protective shell 3, and the transmission gear 5 is meshed with the rack on one side of the lifting rod 2. The transmission gear 5 is coaxially arranged with the driving ratchet 6 through the driving shaft 7. The driving ratchet 6 is meshed with the non-return pawl 8 and the driving pawl 9 respectively. The driving shaft 7 is rotatably arranged inside the protective shell 3 through a bearing. The non-return pawl 8 is rotatably provided on the inner wall of the protective shell 3 through a pin shaft. The non-return pawl 8 is connected to the inner wall of the protective shell 3 by a spring 13. The driving pawl 9 is also rotatably provided on the inner wall of the protective shell 3 through a rotating shaft. The driving pawl 9 can toggle the driving ratchet 6 for unidirectional rotation. The rotating shaft extends out of the protective shell 3 and is provided with a handle 11. When the rotating shaft drives the driving pawl 9 to rotate, the driving When the lifting rod 2 needs to be lowered, the unlocking rod 2 is pulled upward, and the non-return pawl 8 overcomes the action of the spring 13 and rotates upward and no longer brakes the driving ratchet 6, so that the driving ratchet 6 can reverse with the transmission gear 5; in this specific embodiment, the driving shaft 7 and the driving ratchet 6 are an integrated structure, and the driving shaft 7 is key-connected to the transmission gear 5.

[0029] like Figure 1 As shown, in this specific embodiment, the supporting rod 1 includes a middle part 101, and the two ends of the middle part 101 are respectively threadedly connected with an adjustment part 102, and the end of the adjustment part 102 is provided with an anti-slip cap 103; after such arrangement, the length of the supporting rod 1 can be adjusted, and it can adapt to conveyor belts of various widths, thereby increasing the scope of use of this tooling.

[0030] In this specific embodiment, the hook 4 is an L-shaped structure and can be hung downward on the guardrail crossbar located on the upper part of the conveyor belt. A guide groove is provided in the protective shell 3, and a slider is provided on one side of the lifting rod 2, and the slider can move along the guide groove.

[0031] The working process of this conveyor belt roller replacement tool is as follows:

[0032] Put the support rod 1 under the conveying belt, both ends into the lifting ring 12, the hook 4 is hung on the guardrail of the conveying belt, both sides are driven simultaneously by rotating the handle 11 drive shaft 7 (if necessary, the protective shell 3 can be pressed, to avoid the hook 4 is taken up), the lifting rod 2 rises, drive the support rod 1 to rise, in turn drive the conveying belt to rise, until the appropriate position is reached; after replacing the supporting roller is completed, pull up to unlock the pull rod 10 to achieve unlocking, if necessary (the conveying belt is small in weight), push down the lifting rod 2, and lower the conveying belt.

[0033] From the above specific embodiments, the utility model has the following beneficial effects:

[0034] 1. By adopting the form of lifting the conveying belt to realize the conveying belt lifting, the support rod 1 only needs to establish the connection with the lifting rod 2, and no waiting for the elongation of the support rod 1 is needed, compared with the prior art, the time for adjusting the length of the support rod 1 is saved, the time for lifting the conveying belt is obviously shortened, and the efficiency of replacing the supporting roller is improved;

[0035] 2. The lifting ring 12 is used to realize the sleeve connection of the lifting rod 2 and the support rod 1, the connection efficiency of the lifting rod 2 and the support rod 1 is improved, and the time for lifting the conveying belt is further shortened;
