It realizes continuous transportation of materials from one place to another through friction drive. Belt conveyor has the characteristics of simple structure, easy use, long conveying distance, large conveying capacity and easy maintenance.

[0003] In the prior art, the rollers on both sides may be damaged and need to be replaced. Conventional roller brackets are all integrated structures. The rollers need to be lifted up 50mm-60mm before they can leave the roller groove. This means that before removing the rollers, the conveyor belt needs to be manually lifted up a certain distance. Since the conveyor belt is usually long and heavy, it takes a lot of effort to lift it a certain distance. Especially for heavy and long-distance conveyor belts, the labor intensity of the workers is extremely high, which can easily lead to excessive physical exhaustion. Utility Model Content

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0029] Reference Figure 1 , Figure 3 and Figure 5This embodiment provides a support for a mining belt conveyor roller 2, including a support frame 1 and two rollers 2, the two rollers 2 are respectively located on both sides of the support frame 1, and the two rollers 2 are symmetrically and tilted, so that the conveyor belt supported by them is V-shaped, which plays a role of conveying; rotating frames 3 are rotatably installed on both sides of the support frame 1, and roller grooves are provided on both sides of the rotating frame 3, and the two ends of the rollers 2 are respectively installed in the two roller grooves; and a driving mechanism for driving the rotating frame 3 to rotate is also included;

[0030] When in use, the angle of the rotating frame 3 is controlled by the driving mechanism, so that the roller 2 on the rotating frame 3 supports the conveyor belt. If the roller 2 needs to be replaced, the rotating frame 3 and the roller 2 are rotated when the driving mechanism is operated. After rotating to a certain angle, there will be a certain distance between the roller 2 and the conveyor belt. At this time, the roller 2 can be manually taken out of the roller groove. Compared with the prior art, there is no need to manually lift a part of the conveyor belt, which reduces the physical burden of the staff and avoids the safety risks caused by manually lifting the conveyor belt. In addition, the angle of the rotating frame 3 and the roller 2 is accurately controlled by the driving mechanism, so that the roller 2 can quickly break away from the state of contact with the conveyor belt, which greatly speeds up the replacement speed of the roller 2, reduces the downtime for maintenance, and improves production efficiency.

[0031] As a preferred embodiment of the present invention, refer to Figure 1 , Figure 3 and Figure 5 Two bearing seats 4 are arranged on both sides of the support frame 1. The two bearing seats 4 are arranged along the width direction of the conveyor belt. The two bearing seats 4 are rotatably installed with a rotating shaft 5. The rotating shaft 5 is also arranged along the width direction of the conveyor belt. One end of the rotating frame 3 is lower and the other end is higher, so that the roller 2 is inclined. When the rotating shaft 5 rotates, the rotating frame 3 is driven to rotate around the axis of the rotating shaft 5. The rotating frame 3 and the rotating shaft 5 are fixed together by welding;

[0032] When in use, when the rotating shaft 5 rotates, the rotating frame 3 and the roller 2 are driven to rotate around the axis of the rotating shaft 5. After rotating a certain angle, the roller 2 is separated from the conveyor belt, and then the roller 2 is removed.

[0033] As a preferred embodiment of the present invention, refer to Figure 2 and Figure 4 The driving mechanism includes a gear 6 arranged at one end of the rotating shaft 5, the gear 6 is connected to the rotating shaft 5 by a key connection, and a moving mechanism is arranged on the outer bearing seat 4. A rack 7 is arranged at the output end of the moving mechanism, and the rack 7 is meshed with the gear 6; the moving mechanism includes a screw rod 8 rotatably connected to the bearing seat 4, the screw rod 8 is threadedly connected to a moving plate 9, the rack 7 is arranged on the moving plate 9, and the rack 7 is fixedly connected to the moving plate 9. When the moving plate 9 moves, the rack 7 is driven to move;

[0034] The movable plate 9 is slidably connected to the bearing seat 4;

[0035] The moving mechanism also includes a bevel gear 2 10 arranged at the end of the screw rod 8, the bevel gear 2 10 is connected to the screw rod 8 by a key connection, and a support shaft 11 rotatably mounted on the bearing seat 4, the support shaft 11 is arranged parallel to the rotating shaft 5, and the support shaft 11 is provided with a bevel gear 3 12 meshing with the bevel gear 2 10, and a hand wheel 13 is arranged at the end of the support shaft 11, the hand wheel 13 and the bevel gear 3 12 are both connected to the support shaft 11 by a key connection, and the direction of the bevel gear 2 10 and the bevel gear 3 12 is converted so that the hand wheel 13 faces the outside of the conveyor belt. When operating the moving mechanism, the hand wheel 13 can be controlled on the outside of the conveyor belt to control the angle of the rotating frame 3, so that the operator has more space to implement;

[0036] During use, when it is necessary to adjust the angle of the rotating frame 3, the user is on the outside of the conveyor belt, and rotates the handwheel 13 to drive the screw rod 8 to rotate. Since the screw rod 8 is threadedly connected to the movable plate 9, and the movable plate 9 is slidably connected to the bearing seat 4, the rotating handwheel 13 drives the movable plate 9 and the rack 7 to move. Since the rack 7 is meshed with the gear 1 6, the gear 1 6, the rotating shaft 5, the rotating frame 3 and the roller 2 all rotate. Moreover, due to the threaded transmission, the angle of the rotating frame 3 has a certain self-locking property after the adjustment is completed, which makes the adjustment more convenient.

[0037] As a preferred embodiment of the present invention, refer to Figure 6 The rotating shaft 5 is fixed with a fixing portion 14, and a limiting portion 1 is provided on one side of the bearing seat 4 close to the fixing portion 14;

[0038] The limiting part 1 includes a connecting part 15 arranged on the bearing seat 4, and the connecting part 15 is threadedly connected with an adjusting part 16;

[0039] A second limiting portion is disposed on one side of the bearing seat 4 close to the fixing portion 14, and the first limiting portion and the second limiting portion are located on both sides of the rotating shaft 5 respectively;

[0040] The second limiting part includes a second connecting part 17 disposed on the bearing seat 4, and the second connecting part 17 is threadedly connected with a second adjusting part 18;

[0041] The first limiting part and the second limiting part are both steel plates, and both are fixed to the bearing seat 4 by welding. Figure 6As shown, at this time, the roller 2 is in the working position, the fixing portion 14 contacts the end of the adjusting portion 16, and the adjusting portion 16 serves to limit the rotating frame 3. In order to prevent the rotating frame 3 from rotating too much and causing the roller 2 to be separated from the roller groove, the relative position of the adjusting portion 18 and the connecting portion 17 is adjusted so that when the fixing block contacts the adjusting portion 18, the rotating frame 3 cannot continue to rotate, and at this time the roller 2 cannot be separated from the roller groove under the action of gravity.

[0042] As a preferred embodiment of the present invention, refer to Figure 2 The screw rod 8 is threadedly connected with a nut 19, and there are two nuts 19, and the two nuts 19 are respectively located on both sides of the movable plate 9. Since the conveyor will vibrate during operation, in order to prevent the screw rod 8 from rotating, when the roller 2 is in working state, the nut 19 is rotated to make the nut 19 contact with the movable plate 9, thereby preventing the screw rod 8 from rotating.

[0043] As a preferred solution of the utility model, the adjusting part 16 and the adjusting part 2 18 are both screws, and the screws are threaded with nuts 20. Since the conveyor will vibrate during operation, in order to prevent the screw 8 from rotating, when the roller 2 is in working state, the nut 20 is rotated so that the nut 20 contacts the connecting part 15 or the connecting part 2 17, thereby preventing the screw from rotating.

[0044] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
