Abstract
Description
Technical Field
[0001] This utility model relates to the field of slag transportation technology, and more specifically, to a belt counterweight device for slag transportation. Background Technology
[0002] Belt conveyors are widely used in industrial production as a high-efficiency and continuous conveying device in the transportation of powdery or granular materials such as lithium slag. However, during long-term operation, belts are prone to loosening due to natural stretching and mechanical wear, leading to problems such as belt slippage, misalignment, and even shutdown, affecting the normal operation of the equipment and production efficiency.
[0003] To address the issue of belt slack, existing belt conveyors are typically equipped with tensioning devices, among which counterweight tensioning devices are widely used due to their simple structure and ease of maintenance. These devices generally connect counterweights to the guide roller support of the belt conveyor, utilizing the weight of the counterweights to apply a constant tension to the belt, thus maintaining belt tension. However, in practical applications, it has been found that existing belt conveyor counterweights are usually located in the pit area below the slag discharge port, and this arrangement has several problems. Because lithium slag is prone to dust generation or spillage during transport, some lithium slag leaks from the discharge port and falls into the counterweight pit. Lithium slag has a certain degree of corrosiveness and adhesion; its accumulation around the counterweight not only affects its normal operation but may also cause jamming, corrosion, and other malfunctions, reducing the equipment's service life.
[0004] Furthermore, because the counterweight itself occupies a certain amount of space, the area beneath and around it often becomes a blind spot for slag removal operations, making cleaning difficult. Currently, the main method of cleaning relies on manual entry into the pit for periodic cleaning. This not only increases the labor intensity of workers but also poses significant safety hazards when working under the counterweight, such as the risk of falling objects and mechanical injuries, which is detrimental to safe production management. Utility Model Content
[0005] The purpose of this utility model is to provide a belt counterweight device for slag transportation, which can effectively prevent lithium slag from entering the counterweight area while ensuring the tension of the belt conveyor.
[0006] This utility model is achieved through the following technical solution:
[0007] A belt counterweight device for slag transportation includes a frame, a fixed frame and a movable frame disposed at both ends of the frame, and a counterweight mechanism connected to the movable frame. The fixed frame and the movable frame are connected by a belt. The counterweight mechanism includes a wire rope, a guide rail, and a counterweight block. The guide rail is installed on the frame and located on the side of the movable frame away from the fixed frame. One end of the wire rope is fixedly connected to the movable frame, and the other end of the wire rope is wound around the outside of the guide rail and passes through the frame to be fixedly connected to the counterweight block.

[0028] Example 1
[0029] like Figures 1-4 As shown, this embodiment provides a belt counterweight device for slag transportation, including a frame 1, a fixed frame 2 and a movable frame 3 disposed at both ends of the frame 1, and a counterweight mechanism 5 connected to the movable frame 3. The fixed frame 2 and the movable frame 3 are connected by a belt 4. The counterweight mechanism 5 includes a wire rope 51, a guide rail 52, and a counterweight block 53. The guide rail 52 is installed on the frame 1 and located on the side of the movable frame 3 away from the fixed frame 2. One end of the wire rope 51 is fixedly connected to the movable frame 3, and the other end of the wire rope 51 is wrapped around the outside of the guide rail 52 and passes through the frame 1 and is fixedly connected to the counterweight block 53.
[0030] Moving the counterweight from below the conveyor belt to its end, and changing it from a suspended counterweight to a tensioned counterweight, prevents lithium slag from entering the counterweight area while maintaining conveyor belt tension. This facilitates mechanical cleaning of lithium slag leaking onto the ground, eliminates safety hazards during cleaning, reduces labor intensity, and improves cleaning efficiency. Specifically, counterweight block 53 is located at the end of the conveyor belt, with a certain distance between it and the belt 4. This prevents lithium slag on the belt 4 from falling into the counterweight area, enabling automatic cleaning of the counterweight area.
[0031] In one embodiment of this example, the fixed frame 2 includes a rectangular frame 21, which is connected to the machine frame 1 by bolts, and a roller 22 is provided on the top of the frame 21.
[0032] In one embodiment of this invention, the movable frame 3 includes a rectangular frame 31. A roller 32 is mounted on the top of the frame 31, and rollers 33 are arranged around the perimeter of the frame 31. The rollers 33 slide in contact with the frame 1. The belt 4 is connected to both the first roller 22 and the second roller 32. The frame 31 can be pulled by a counterweight 53, a guide rail 52, and a wire rope 51, thereby adjusting the distance between the frame 31 and the first frame 21 and achieving rapid tensioning of the belt 4.
[0033] In one embodiment of this invention, a fixed seat 34 is provided on the top of the frame 31 near the counterweight mechanism 5, and the wire rope 51 is sleeved on the fixed seat 34. The connection between the wire rope 51 and the fixed seat 34 facilitates the replacement of the wire rope 51.
[0034] In one embodiment of this invention, mounting bases 6 are provided on the top of the first frame 21 and the second frame 31, and the first roller 22 and the second roller 32 are rotatably connected to the mounting bases 6. Specifically, bearings can be used to achieve the connection.
[0035] In one embodiment of this invention, the movement direction of the counterweight 53 is perpendicular to the movement direction of the movable frame 3.
[0036] In one embodiment of this invention, a protective housing 54 is provided on the outside of the counterweight 53. The protective housing 54 can isolate the counterweight 53, preventing operators from entering the counterweight area and improving safety.
[0037] In one embodiment of this invention, the counterweight 53 includes a base plate 531 and a counterweight plate 532. The wire rope 51 is fixedly connected to the base plate 531, and the counterweight plate 532 is detachably connected to the base plate 531. The detachable design of the counterweight plate 532 and the base plate 531 allows for adjustment of the counterweight weight to accommodate different degrees of slack in the belt 4. Specifically, a slot is provided on the counterweight plate 532, and the wire rope 51 is secured within the slot, enabling a quick connection between the counterweight plate 532 and the base plate 531.
[0038] The working principle is as follows: Lithium slag is transported on belt 4. When the belt 4 experiences tension slack, the counterweight 53, guide rail 52, and wire rope 51 work together to pull frame 21, causing frame 21 to move away from frame 21 on the frame 1. Adjusting the distance between frame 21 and frame 21 achieves tensioning of belt 4. Furthermore, the number of counterweight plates 532 on counterweight 53 can be adjusted to regulate the pulling force of counterweight 53 on frame 21, thus adjusting the tension of belt 4.
[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
