Description

Technical Field

[0001] The utility model relates to the technical field of conveying, in particular to a deviation prevention mechanism for a long-distance belt conveyor. Background Art

[0002] Belt conveyor, also known as belt conveyor, is a widely used continuous transportation machinery. Its working principle is based on friction drive, that is, the traction force is transmitted through the friction between the driving roller and the conveyor belt, so that the conveyor belt and the materials on it can be transported from the feeding point to the unloading point along the predetermined conveying route.

[0003] Belt conveyors are widely used in various fields of industry. To ensure the stable operation of belt conveyors, they are usually adjusted during installation and commissioning by means of tail rollers, counterweights, and self-aligning brackets. However, since belt conveyors are generally installed outdoors, the friction on the back of the belt will be reduced due to weather conditions (such as rain), which will cause the belt conveyor to deviate. Even indoors, the friction will be affected by the mixing of materials on the back of the belt, which will also cause the belt to deviate. Therefore, when installing a belt conveyor, roller brackets with self-aligning functions will be installed in sections, and the brackets are generally equipped with more than two anti-deviation vertical rollers. These two anti-deviation rollers have a very simple structure, are easy to disassemble and assemble, and have low cost, so they are widely used, but they also have the following disadvantages: Since the roller wall is only 2.75mm, the roller is very easy to be damaged when the belt conveyor deviates. Since the distance between the roller and the belt conveyor is very close, in order to ensure safety, maintenance work is not allowed when the belt conveyor is running. Therefore, if the roller needs to be replaced, the belt conveyor must be stopped, which will be very troublesome for some companies that require continuous production. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a long-distance belt conveyor anti-deviation mechanism, which has a simple structure and at least two vertical rollers are installed at the same deviation correction position. When a vertical roller is damaged during operation, a new vertical roller can be quickly switched to support the belt without stopping the machine for processing.

[0005] The utility model discloses a long-distance belt conveyor anti-deviation mechanism, comprising a bracket with rollers; both sides of the bracket are rotatably mounted with a rotating shaft, the rotating shaft is provided with a middle part of a fixed frame, and at least two vertical rollers are rotatably mounted on the end of the fixed frame;

[0006] It also includes a driving mechanism, which is used to drive the rotating shaft to rotate.

[0007] As a preferred solution of the utility model, both ends of the vertical roller are rotatably connected with sliders, the sliders are slidably connected to the fixing frame, and the sliders are fixedly connected to the fixing frame through a locking piece.

[0008] As a preferred solution of the utility model, the driving mechanism includes a gear arranged on the rotating shaft, a bearing seat arranged on the bracket, the bearing seat is rotatably connected to a screw rod, and the screw rod is threadedly connected to a moving plate;

[0009] The movable plate is slidably connected to the bracket, and the movable plate is provided with a rack meshing with the gear;

[0010] A hand wheel is installed at the end of the screw rod.

[0011] As a preferred solution of the utility model, the driving mechanism further comprises a nut threadably connected to the screw rod.

DETAILED DESCRIPTION

[0023] 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.

[0024] 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.

[0025] 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

[0026] Reference Figure 1-Figure 4 This embodiment provides a long-distance belt conveyor anti-deviation mechanism, including a bracket 2 with a roller 1; a rotating shaft 3 is rotatably installed on both sides of the bracket 2, and the axis of the rotating shaft 3 is perpendicular to the plane where it is located. The rotating shaft 3 is provided with a middle portion of a fixed frame 4. More specifically, the fixed frame 4 is two connecting plates, and the two connecting plates are fixedly connected to the rotating shaft 3. At least two vertical rollers 5 are rotatably installed at the end of the fixed frame 4. In this embodiment, two vertical rollers 5 are provided, and the two vertical rollers 5 are arranged in a circular array with the axis of the rotating shaft 3 as the axis;

[0027] It also includes a driving mechanism, which is used to drive the rotating shaft 3 to rotate;

[0028] In this embodiment, during normal use, the vertical rollers 5 are provided to prevent the belt from running off track. When one of the vertical rollers 5 is damaged, the shaft 3 is rotated by the driving mechanism, and the two vertical rollers 5 revolve around the axis of the shaft 3, so that the spare vertical rollers 5 are automatically rotated to the working position, which greatly shortens the maintenance time and improves the continuous operation capacity and production efficiency of the transmission system. After the damaged vertical roller 5 rotates to the side away from the conveyor belt, the maintenance worker can perform maintenance, which greatly increases the distance between the maintenance worker and the belt conveyor, and improves the safety of the maintenance work.

[0029] As a preferred solution of the utility model, both ends of the vertical roller 5 are rotatably connected with a slider 6, the slider 6 is slidably connected to the fixing frame 4, and the slider 6 and the fixing frame 4 are fixedly connected by a locking member 7. In this embodiment, the locking member 7 is a screw. In order to improve the fixing effect, a single slider 6 is provided with two screws, and the screws are threadedly connected to the slider 6. When the slider 6 is moved to a suitable position, the screws are tightened to keep the slider 6 and the fixing frame 4 fixed;

[0030] More specifically, the fixing frame 4 is provided with a long notch 17, and the slide block 6 slides in the long notch 17. Figure 2 and Figure 4 As shown, one end of the long notch 17 is connected to the end of the fixing frame 4. After the locking member 7 is released, the slider 6 can be quickly separated from the fixing frame 4, so that the vertical roller 5 can be quickly removed and then replaced with a new vertical roller 5.

[0031] In this embodiment, by adopting the sliding connection design between the slider 6 and the fixing frame 4 and using the locking member 7, when the vertical roller 5 needs to be replaced, the slider 6 can be quickly moved along the long notch 17 by simply loosening the screw, thereby easily removing the old vertical roller 5 and installing a new vertical roller 5. This design greatly simplifies the replacement process and shortens the maintenance time.

[0032] As a preferred solution of the utility model, the driving mechanism includes a gear 8 arranged on the rotating shaft 3, the gear 8 is connected to the rotating shaft 3 by a key connection, a bearing seat 9 is arranged on the bracket 2, the bearing seat 9 is fixedly connected to the bracket 2, the bearing seat 9 is rotatably connected to a screw rod 10, and the screw rod 10 is threadedly connected to a moving plate 11; the moving plate 11 is slidably connected to the bracket 2, and the moving plate 11 is provided with a rack 12 meshing with the gear 8; a hand wheel 13 is installed at the end of the screw rod 10; the driving mechanism also includes a nut 14 threadedly connected to the screw rod 10, and the nuts 14 are at least two, and the nuts 14 are distributed on both sides of the moving plate 11;

[0033] In this embodiment, the screw rod 10 is driven to rotate by manually rotating the hand wheel 13, thereby pushing the movable plate 11 and the rack 12 to slide along the bracket 2. Since the gear 8 is meshed with the rack 12, the rotating hand wheel 13 can make the rotating shaft 3, the fixed frame 4 and the vertical roller 5 rotate around the axis of the rotating shaft 3, so that the spare vertical roller 5 can be quickly rotated to the working position. At least one nut 14 is distributed on both sides of each movable plate 11. After the position of the vertical roller 5 is adjusted, the nut 14 is tightened to make it contact with the movable plate 11. This design can effectively prevent the screw rod 10 from rotating during the stopping process. When the vertical roller 5 supports the conveyor belt, the angle between the vertical roller 5 and the conveyor belt remains unchanged, thereby improving the stability and reliability of the entire system.

[0034] As a preferred solution of the utility model, a positioning line 15 is provided on one side of the bracket 2 close to the roller 1;

[0035] The rotating shaft 3 is provided with a pointer 16 corresponding to each of the vertical rollers 5. The pointer 16 is fixedly connected to the rotating shaft 3 and is located directly below the middle position of the roller 1. The pointer 16 is arranged along the radial direction of the rotating shaft 3. When the vertical roller 5 is in the working position, the pointer 16 corresponding to the vertical roller 5 is facing the positioning line 15.

[0036] In this embodiment, the pointer 16 rotates with the rotating shaft 3. When the pointer 16 corresponding to the vertical roller 5 is facing the positioning line 15, the vertical roller 5 is in the working position. By aligning the pointer 16 with the positioning line 15, the operator can intuitively and quickly determine whether the vertical roller 5 is in the correct working position. This method simplifies the alignment process and reduces improper installation caused by human judgment errors.

[0037] As a preferred solution of the utility model, both ends of the central axis of the vertical roller 5 are rotatably connected to the slider 6 through bearings. The bearings provide precise central support for the vertical roller 5, ensuring that the vertical roller 5 maintains the correct axial and radial positions during rotation, which is crucial to maintaining the smooth operation of the conveyor belt and preventing deviation.

[0038] 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.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
